The study, analyzing measurements of the supermassive black hole mass function, was carried out by two Australian cosmologists: Chas A. Egan from the Australian National University in Canberra, and Charles H. Lineweaver from the University of NSW in Sydney. Their results indicated the entropy at the current cosmic event horizon is much greater than the entropy of the interior of the universe, and the total cosmic entropy is about 100 times greater than previous calculations.Entropy increases as the number of ways the system can be arranged microscopically without changing the external appearance increases. Egan used the example of hot water being poured into a cold bath. Before the hot and cold water meet they are separate and orderly and the system has low entropy. When the hot and cold water are well mixed, the entropy is high and no heat flow between the two is possible.Egan and Lineweaver found the collective entropy of the supermassive black holes was around 100 times higher than expected. Since these black holes contribute more to the entropy in the universe than anything else, the results imply that the entire cosmic entropy is also a 100 times greater than earlier estimates.Previous calculations of the cosmic entropy assumed the presence of a 10 million solar-mass black hole at the center of each galaxy, and the entropy was calculated using an estimated average mass. Egan and Lineweaver had access to more recent data that gave them the range of supermassive black hole masses rather than an average. Egan said the study revealed a smaller number of larger supermassive black holes contribute much more to the entropy than previously believed.The universe has much lower entropy than is theoretically possible, and this is still true, even with the new calculations. This is just as well because the entropy of the universe must be below the maximum theoretical value or life and other complex phenomena will cease to exist. As the entropy gradually increases it will eventually approach the theoretical maximum, a state many physicists have called the heat death of the universe. The new calculation takes the universe a little closer, but it is still only a billionth of a billionth of the maximum.Not every scientist agrees that the higher entropy takes the universe closer to heat death. Ned Wright of the University of California in Los Angeles, for example, suggests the entropy is locked inside the supermassive black holes, and so the rest of the universe has lower entropy and is therefore further away from heat death.More information: The paper was published online at arXiv.org.via Sciencenews.org© 2009 PhysOrg.comlast_img read more

Lithiumair batteries high energy density could extend range of electric vehicles

first_img(PhysOrg.com) — For today’s electric vehicles that run on lithium-ion batteries, one of the biggest downsides is the limited range between recharging. Over the past several years, researchers have been working on an alternative battery called a lithium-air battery. These batteries could significantly increase the range of electric vehicles due to their high energy density, which could theoretically be equal to the energy density of gasoline. Explore further A lithium-air battery developed at MIT. Image credit: Patrick Gillooly/MIT. More information: via: IEEE Spectrum Citation: Lithium-air batteries’ high energy density could extend range of electric vehicles (2011, February 1) retrieved 18 August 2019 from https://phys.org/news/2011-02-lithium-air-batteries-high-energy-density.html At the fall meeting of the Materials Research Society in Boston, Ming Au, a scientist from the Savannah River National Laboratory in Aiken, S.C., said that no other known battery has as high of an energy density as lithium-air batteries. Researchers estimate that these batteries could hold 5-10 times the energy of lithium-ion batteries of the same weight, and twice the energy for the same volume.Lithium-air batteries have an anode made of lithium and an “air cathode” made of a porous material that draws in oxygen from the surrounding air. When the lithium combines with the oxygen, it forms lithium oxide and releases energy. Since the oxygen doesn’t need to be stored in the battery, the cathode is much lighter than that of a lithium-ion battery, which gives lithium-air batteries their high energy density.At the meeting, Au said that his research group has demonstrated a coin-sized rechargeable lithium-air battery with a current density of 600 mAh/g, which is much higher than the current densities of 100 to 150 mAh/g of lithium-ion batteries. But one of the biggest challenges facing lithium-air batteries is their limited number of charge/discharge cycles. Whereas lithium-ion batteries can be recharged more than 100,000 times, Au’s lithium-air battery can be recharged only about 50 times. Although single-use lithium-air batteries are already being used, for example to power hearing aids, electric vehicles require batteries that can be recharged thousands of times.The biggest problem with recharging lithium-air batteries is that it’s very difficult to convert the lithium oxide back into lithium. Currently, researchers can do this only by using catalysts, and even then some of the lithium oxide cannot be converted because it builds up in the battery. Researchers also face challenges in speeding up the recharging process and in keeping water vapor out of the oxygen, since lithium reacts violently with water.At the meeting, Au said that rechargeable lithium-air batteries would probably not be commercially available for several years, noting that lithium-ion batteries were first proposed in the 1970s but not commercialized until 1997. (Lithium-air batteries were first demonstrated in the mid-‘90s.) Au added that a “big investment from the government or some corporation” would have to be secured for developing a commercial product. © 2010 PhysOrg.com This document is subject to copyright.

Makers of infamous BigDog robot unveil human version PETMAN w video

first_img Interestingly, the robot wasn’t made to scare anyone, or even to go into battle. It was designed to mimic the way human soldiers move so as to test army clothes for use in hazardous environments, i.e. chemical warfare. In addition to moving like a human being, it also simulates breathing and sweats when made to do a lot of work, like running and doing pushups. Because of its purpose, the engineers at Boston Dynamics haven’t yet completed a neck and head, which means PETMAN (Protection Ensemble Test Mannequin) has nothing on his shoulders but a blinking red light. And speaking of lights. He, or it, also has an eerie blue glow going on behind his chest plate. Not sure why, but it absolutely adds to the scariness of the big guy.

Boston Dynamics, makers of the BigDog robot that can haul stuff around for the military has released a video of PETMAN, a human version that looks like a combination of the Terminator and a Cylon from Battlestar Galactica. Maybe even scarier is the fact that it walks like John Wayne; just enough attitude to let you know he’s not someone to be messed with. © 2011 PhysOrg.com PETMAN is just under six feet tall, and weighs close to 180 pounds, which is what you get if you average the height and weight of the average human American soldier. He’s also tethered, which softens the fear factor a bit, but not really all that much when it is recalled that BigDog was tethered when first seen on video too.Boston Dynamics was founded by some really smart people from MIT, and it’s funding for most of its projects such as this one ($26.3 million) come from the U.S. Defense Department, e.g. DARPA. And while the DoD maintains that it’s reason for paying for the creation of PETMAN is to test uniforms, it’s hardly likely that it’s interest will remain there indefinitely as it’s hard to ignore the emotional reaction that most people experience upon viewing the video. Seeing it in person, weaponized, on the battlefield, likely would inspire a new level of terror in enemy combatants and could conceivably lead to changes in the ways unconventional wars are fought.

Nanoscale MRI being developed

first_img(Phys.org)—Two independent groups of scientists in the U.S. and Germany have reduced magnetic resonance imaging (MRI) down to the nanoscale, which may enable them in the future to non-destructively detect and image small molecules such as proteins at room temperature and pressure. Previously, nanoscale imaging was only possible at extremely low temperatures and pressures. Journal information: Science MRI works through detecting weak electromagnetic fields produced by the nuclei of atoms such as hydrogen within the molecules being studied, and the collective resonance of these fields. It is able to image structures without destroying them, which makes it useful for scanning bodies, but its relatively low sensitivity has up to now restricted its use on the small scale to chemicals with volumes measured in micrometers at best.Two papers published in the journal Science describe the research done by the two separate groups, which both used dark spots, or nitrogen-vacancy (NV) defects, on the surface of diamonds. Diamond is inert magnetically because it consists entirely of carbon atoms bonded covalently, and there are no free electrons. However, there can be imperfections such as NVs, in which a single carbon is replaced by a nitrogen atom, adjacent to a vacancy in the lattice where a carbon atom is missing. The NVs have a free electron, which gives it unique magnetic properties, and it is these properties the two research teams exploited.The first team, led by Daniel Rugar and John Mamim of the Almaden Research Center in San Jose, California, used diamond dark spots to detect weak magnetic fields in materials near the diamond surface. Rugar’s group synthesized extremely pure diamond with NV centers close to the surface and overlaid it with a polymer 60 nanometers thick. They then applied an oscillating magnetic field. Dr. Rugar explained that when you shine green light on the dark spots they fluoresce in red, and the brightness depends on the NV center’s magnetic state. External magnetic fields in the vicinity can affect the spin of the NV center electron, which in turn affects the brightness of the fluorescent red.The second team, led by Friedemann Reinhard of the University of Stuttgart, also used nitrogen-vacancy defects on extremely pure samples of synthesized diamond, but they used them to record the NMR spectra of a range of chemicals placed on the surface of the diamond. Dr. Reinhard said their method was more passive than the methods used by Rugar’s team, but this makes it a little easier to implement.The research is important because it is difficult to determine protein structures conventionally, which involves expressing and purifying the proteins and then crystallizing them. Being able to take an MRI image would simplify the process and enable the structures of all proteins to be worked out. At the moment the research of both teams is at a “proof of principle” level, according to Rugar’s team, and more research is needed before the techniques can be used to image molecules.

We demonstrated the use of an individual, near-surface nitrogen-vacancy (NV) center in diamond as a sensor to detect proton NMR in an organic sample located external to the diamond. Using a combination of electron spin echoes and proton spin manipulation, we showed that the NV center senses the nanotesla field fluctuations from the protons, enabling both time-domain and spectroscopic NMR measurements on the nanometer scale.2.

Its detection volume consisted of only 104 nuclear spins with a net magnetization of only 102 statistically polarized spins.center_img © 2013 Phys.org Citation: Nanoscale MRI being developed (2013, February 1) retrieved 18 August 2019 from https://phys.org/news/2013-02-nanoscale-mri.html ‘Critical baby step’ taken for spying life on a molecular scale Explore furtherlast_img read more

Researchers find easy way to deposit metal nanoparticles on a surface using

first_img Coating noble metal nanoparticles with silica © 2015 Phys.org This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. More information: Mechanochemical Activation and Patterning of an Adhesive Surface toward Nanoparticle Deposition, J. Am. Chem. Soc., 2015, 137 (5), pp 1726–1729. DOI: 10.1021/ja507983xAbstractMechanical pulling of adhesive tape creates radicals on the tape’s surface. These radicals are capable of reducing metal salts to the corresponding metal nanoparticles. In this way, the mechanically activated tape can be decorated with various types of nanoparticles, including Au, Ag, Pd, or Cu. While retaining their mechanical properties and remaining “sticky,” the tapes can exhibit new properties derived from the presence of metal nanoparticles (e.g., bacteriostaticity, increased electrical conductivity). They can also be patterned with nanoparticles only at selective locations of mechanical activation. Journal information: Journal of the American Chemical Society Adding metal nanoparticles to a surface offers a way to confer properties onto it that would not be present otherwise—allowing rubbers to conduct electricity, for example. But, getting metal nanoparticles to adhere to desired products oftentimes involves a lot of time, effort or money (not to mention hazardous waste byproducts) which can detract from its usefulness. In this new effort, the researchers found that common, inexpensive sticky tape provides an opportunity for adding nanoparticles to a surface in a simple, clean way.The researchers note that unspooling sticky tape from its roll causes bonds within the tape polymer to break which results in radicals forming on its surface—radicals that are attracted to metal nanoparticles. That meant, all they had to do was create a liquid solution with nanoparticles in it, drop a length of sticky tape into it and let it soak for awhile. The nanoparticles bonded with the radicals causing them to adhere, forming a layer on the tape material made of the nanoparticles, and that imbued the sticky tape with the attractive properties of the metal nanoparticles.Using this method, the team created sticky tape strips with gold nanoparticles to increase electrical conductivity, copper to allow it to be used as a fungicide and silver to allow for use as an antibiotic. They noted that their process did not cause a reduction in stickiness, which meant the tape could still be applied to another surface, adding to its desirable attributes. Also they noted that the technique could be adapted to tapes not on a roll by using physical pressure to release the radicals. As one example, they placed a length of sticky tape into a bath of silver nitrate for a few hours—it turned yellow-orange, indicating that the silver in the bath had indeed formed a layer on the tape. (Phys.org)—A combined team of researchers from Northwestern University in the U.S. and Bilkent University in Turkey has found that ordinary Scotch tape can be used to create a metal nanoparticle surface. In their paper published in the Journal of the American Chemical Society, the team describes how they used ordinary sticky tape to create the surfaces and why it worked so well.

New Research From Psychological Science

first_imgUsing a Psychopharmacogenetic Approach To Identify the Pathways Through Which — and the People for Whom — Testosterone Promotes AggressionShawn N. Geniole, Tanya L. Procyshyn, Nicole Marley, Triana L. Ortiz, Brian M. Bird, Ashley L. Marcellus, Keith M. Welker, Pierre L. Bonin, Bernard Goldfarb, Neil V. Watson, and Justin M. Carré Racial Bias in Perceptions of Size and Strength: The Impact of Stereotypes and Group DifferencesDavid J. Johnson and John Paul Wilson Testosterone seems to increase aggression in men with certain personality characteristics, such as high dominance and low self-control, and this effect may be enhanced when those men also have a specific characteristic in their androgen receptor (AR) gene, this research suggests. Participants were men between 18 and 40 years old who completed personality questionnaires and provided a mouthwash sample for DNA extraction. In a task to measure the effects of testosterone on aggression, they were given either testosterone or placebo and were told they would play a game against a player who was in another room (this player was fictitious). In the game, participants received points exchangeable for money by repeatedly pressing a key on the keyboard, but those points could be stolen by the other player; when points were stolen, participants could respond by stealing points from the other player, but the stolen points would not be exchangeable for money. Choosing to steal points caused harm to the other player without any benefit for the participant and was thus used as a measure of aggression. Testosterone promoted aggression during the game among participants with high-risk personality profiles for aggression (high dominance, low self-control, and independent self-construal). This effect was enhanced among men who had more efficient AR genes, related to fewer cytosine-adenine-guanine repeats in the AR gene. These men also reported experiencing more pleasure but not anger during the aggression, which can indicate involvement of reward-related neurotransmitters (i.e., dopamine) on the heterogeneous effects of testosterone on aggression. Race influences judgments of size and strength, but those judgments are primarily based on objective physical features (e.g., bicep circumference), this research suggests. College students estimated other college students’ strength by looking at their full-body photos. Both groups included Asian, Black, and White students. Men with larger bicep circumference and more upper body strength were rated as stronger, but race also affected the ratings: Black men were perceived as stronger than White men, and Asian men were perceived as weaker than White men. The same pattern was obtained for women. Raters’ race and gender did not affect their ratings. In a second experiment, in which participants also rated height, a similar pattern of effects was obtained, and Asian men and women were rated as shorter than Black and White men and women. These results indicate that race impacts judgments of strength, but it does not necessarily decrease accuracy, as some biases derive from physical differences between groups, such as height (e.g., Asian men are on average shorter than White and Black men, and therefore race may reflect an actual physical difference). However, in the absence of individuating information, race may bias decisions more. This research may inform how we think about social issues such as police use of force —­ officers can use lethal force only when a person is a threat, so misjudgments of strength and size based on race may lead to the wrongful use of lethal force. center_img Reactivation of Previous Experiences in a Working Memory TaskGi-Yeul Bae and Steven J. Luck Recent experiences can have a large and automatic impact on the way we perceive and act on current events, even when those previous experiences are irrelevant for the current ones. Bae and Luck investigated whether these influences occur (a) because the past experiences change the synaptic connections among neurons and indirectly influence the way the current information is processed or (b) because the current events trigger an active representation of the previous experience, which directly impacts current processing. The researchers recorded event-related potentials (ERPs) while participants estimated stimuli orientations. On each trial, participants saw a teardrop-shaped stimulus and, after it disappeared, adjusted the orientation of a similar stimulus to match the orientation of the preceding one. Because the ERP data provided temporal information as well as the scalp distribution of brain activation, they allowed the researchers to decode previous-trial activation (due to a given stimulus orientation) from current-trial activation (due to a new orientation). Decoding of previous-trial activation began shortly after the current-trial stimulus was shown, which indicated that the current stimulus reactivated a representation of the previous trial, even though it was now irrelevant. Participants also tended to report orientations biased away from the orientation on the previous trial. Current events may thus trigger an active representation of previous events, potentially explaining how recent past experiences influence current processing.last_img read more

Indian chefs go gaga over mustard oil

first_imgMustard oil has been used for centuries as a food additive and remains a staple in a majority of Indian homes. Incorporating mustard oil into your daily diet is known to protect against heart disease. The oil is rich in monounsaturated fats and polyunsaturated fats, both of which help lower bad cholesterol and raise good HDL cholesterol hence maintaining one’s cholesterol balance, which in turn leads to healthy cardiac functioning. “Mustard oil also works well as an antibacterial, antiviral and antifungal agent and can help fight bacterial infections in the digestive system,” said Executive Chef Arun Sundararaj. Also Read – Add new books to your shelf”From the taste point of view, mustard oil is an acquired taste for most people. Although pungent in character, mustard oil brings tremendous flavours to any dish. I believe that there is no ingredient that comes close to it – mustard oil has a unique texture to it. At the Taj Mahal Hotel, New Delhi, we use mustard oil in dishes such as Mustard Prawns and Bhatti Murgh,” he said.At the same time, Sundararaj adds, “It is recommended that one does not use mustard oil as the sole medium for cooking and instead uses a combination of different oils depending on the dish you are cooking. Mustard oil has a high smoking point and as a result, is ideal for deep frying.” Also Read – Over 2 hours screen time daily will make your kids impulsiveExecutive Chef Sonu Koithara had a similar take on the benefits from the health and palate point of view of cooking in mustard oil.Noting that mustard oil has culinary as well as therapeutic uses, Koithara said, “It has an edge over other oils due to the optimum ratio of omega-3 and omega-6 fatty acids and its low content of saturated fats. It contains about 60 per cent monounsaturated fats (MUFA), as well as polyunsaturated fats (PUFA), and saturated fats. These fatty acids are considered ‘good fats’.” He also pointed to research which suggests that mustard oil has strong cancer-fighting properties and that it contains ample amounts of linolenic acid, which when converted to omega-3 fatty acid, helps prevent cancers.”Mustard oil also benefits the heart as it contains rich amounts of MUFA and PUFA as well as omega-3 and omega-6 fatty acids. These good fats lower the risk of developing heart diseases and is also a very powerful natural stimulant and improves digestion and appetite by stimulating digestive juices,” Koithara explained.Umesh Verma, DGM at Puri Oil Mills Ltd said, “Mustard oil is the preferred choice of generations of chefs across traditional Indian cuisine spanning Kashmir, Punjab and West Bengal as it bring alive the flavour of food.””Indians like to carry the taste of India to whichever country they move to – and find ingenious ways to track down their favourite brands in those countries. We keep hearing of our mustard oil being available in the US and in various European cities. It’s a great feeling.”Are there any foods that particularly lend themselves to being cooked in mustard oil?The oil is one of the best-suited for Indian homes because of its versatility, Sundararaj said, adding it complements Indian spices and beautifully brings out the flavours of our food.”While mustard oil complements both vegetarian and non-vegetarian ingredients, dishes such as pickles of all kinds taste best when made in mustard oil. In addition, mustard oil can be used as a salad dressing along with lemon and honey.”Also there are many Bengali fish preparations like sarson bata maach, paturi fish and other dishes like mangsho (mutton), murgir jhol (chicken) are best enjoyed when cooked in mustard oil,” he said.For, Koithara, the use of mustard oil in Bengali food “is immense and it absolutely complements the Bengali palate. Foods like Shorshe bata ilish and Chingri bhapa are delicacies that cannot do without the generous use of mustard oil”.Any other thoughts they’d like to share on the subject?”There are some ingredients that can never be replaced in the Indian kitchen and mustard oil is one such essential because of its unique and pungent flavour,” Sundararaj said.Pointing to mustard oil’s immense health benefits, Koithara said it is very good during winter as it produces body heat and protects the body from cold.”For this reason, people in Rajasthan use mustard oil on their bodies during winter to keep the skin supple and themselves healthy. Additionally, mustard oil has been used extensively as a cure for cold and cough for decades,” he added.last_img read more

Whats wrong with Cam Newton saying hell be the greatest ever

first_imgCam Newton published a video commentary on ThePlayersTribune.com today titled “In My Mind”, which he directed and produced (we’re not talking “Man on Wire” here, more like Skype with a filter). In the video, he talked about a number of things, including a healthy dose of his favorite topic, himself.When discussing NFL career goals, Cam said exactly what you would expect Cam to say, “There’s no doubt in my mind that I will, and want to be, the greatest football player to ever to play this game.”There it is. Should he lie?Critics wasted no time in roasting Cam for coming off like self-absorbed jerk, while his fans say it shows the cockiness that makes him great. Par for the course for the NFL MVP.“I will and want to be the greatest football player to ever play this game.”Inside the mind of @CameronNewton. pic.twitter.com/AZq4tBzKqT— The Players’ Tribune (@PlayersTribune) August 31, 2016Today on Speak for Yourself, Colin and Jason were asked whether the video came off as over-the-top cocky, or displayed the confidence you expect from a transcendent talent.Colin said he’s not crazy about the video, but if given the choice between a confident QB or a scared one, he’ll take confident.“I don’t love it, but I’d rather see confidence than fear. And some of these young quarterbacks, you see Jared Goff, don’t feel like they’re ready for it.”Jason said he’s all-in on Cam, but wasn’t buying the video and thought it lacked self awareness.“Coming off the way he ended that Super Bowl, I wanted to hear a guy talking about the team. I think 34 times in that video he says “I”. I think 7,8 times he says “we”. I think he talks about “me” and “my” a lot. It was all about Cam.”Cam is the definition of the polarizing superstar. Love him or hate him, you’ll watch him either way.“Cam Newton’s ego fits his ability. Kaepernick’s ego does not” @ColinCowherd on Cam’s braggadocios video post. pic.twitter.com/3HHr6vVa93— Speak For Yourself (@SFY) August 31, 2016last_img read more

Kevin Durant joining the Warriors wasnt the easy way out

first_imgKevin Durant joining the Warriors wasn’t the easy way outKevin Durant is sitting atop the basketball world after winning his first title and securing the MVP. It’s impossible to say that Durant made the wrong decision to leave Oklahoma City and join the Warriors.Even though critics view KD’s move as taking the path of least resistance to a title, Colin thinks it was courageous because he knew he would get killed for joining a 73-win team, but trusted his instinct to pursue opportunity instead. The easy thing would have been to stay in Oklahoma City. It’s hard to argue he was wrong, after a legacy cementing Finals.In the end, KD’s story is a typical American story of moving to a better situation is what America is all about.LeBron and KD did what many of you have, or will do, repeatedly in your life. It is completely un-American to not embrace what Kevin Durant did.” Guests:Chris Broussard – FS1 NBa Analyst is in-studio to discuss the impact of the Warriors win on the NBA; if Paul George to the Cavs would even the competitive balance against Golden State; and why LeBron won’t leave Cleveland, yet.Damon Bruce – Bay area radio host joins the show to talk Warriors’ dominance; why they can last, and why Klay Thompson will remain content with his role on Golden State.Jim Jackson – FS1 NBA Analyst and 14-year NBA veteran is in-studio to explain why dynasties aren’t bad for the NBA and why people don’t really want competitive balance.Rob Parker – FS1 Analyst is in-studio to explain why LeBron will never be the G.O.A.T. and why his Finals losses are a permanent blemish. LeBron James didn’t hurt his legacy in the Finals, he helped itThe Cavs suffered their second Finals loss to the Warriors, and even though LeBron averaged a helthy triple double in the series, the Warriors endless fire power was ultimately too much to overcome.Today, critics are saying that the Finals loss diminishes his legacy, but he was unquestionably the best player on the floor, for either team, in his 14th year. In Jordan’s 14th year, he was leading the Wizards to a sub .500 record.LeBron isn’t even close to being done yet, and looks to have several peak years left. When it’s all said and done, Jordan’s 6 for 6 Finals record will be the only thing Jordan has over James.“LeBron’s the greatest overall basketball player I’ve ever seen.”last_img read more

When Your Product Design Makes Your Customers Feel Smart

first_img Opinions expressed by Entrepreneur contributors are their own. 4 min read March 28, 2014 This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now Users love products and services that make them feel smarter. The more efficiently they can spend their valuable attention, time and money, the smarter they feel. The smarter that users feel when interacting with your product, the more they love it. We call this the smart-user theorem.Strong examples of the smart-user theorem in action abound. Facebook and Instagram save users time by enabling them to connect and share with friends and family quickly and efficiently. Similarly, apps have become popular and ubiquitous, partly because of their availability to fulfill virtually any need or task. Related: The Secret to Successful Product Design? Simplicity.The simplicity of the interface and the entire value chain on the iPad, the ease of planning a trip on Expedia via a mobile device or using Dropbox to store files — these are more examples that offer powerful guiding principles for enterprises as they engage customers with their products and services.Taking this a step further, analyzing customers’ behavior can quantify the time, attention or effort required to engage with a business’ products and services and bring about a new understanding of the user experience. This awareness, in turn, arms businesses with strategies to fine-tune their products and services to be more efficient, streamlined and intuitive.If enterprises carefully evaluate and optimize their products and services to make their users “smarter,” they will be rewarded with loyalty, engagement and a higher transactional value.Related: What Really Fosters Innovation (Infographic)User investments: attention, time and money. There are three types of “capital” that customers invest in your products and services: attention, time and money. First, users turn their attention to your messages, advertisements and product communications. They interpret and internalize your message to inform their next steps.Consumers also spend time thinking about, searching for, discovering, deciding to access, learning about and using your products and services; it’s safe to assume that they spend the same amount of time learning about your competition. Finally, there’s the money part. This one’s pretty obvious: Users pay you for your products and services.The attention, time and money model provides a framework to optimize the design of the end-to-end user experience. Maximizing the value of the attention, time and money spent by users on your products and services can be achieved through a combination of baselining and experimentation.Baselining involves breaking up the product-usage flow into logical stages and measuring the time and attempts it takes users to move through it. In addition, the consumer’s reliance on certain information and features should be analyzed to understand whether they encourage a person to move to the next stage in the flow.Experimentation is the stage whereby, through the use of data analysis or customer interviews, product problems can be identified. Hypotheses are developed and then tested through changes in the product flow until the desired goals are met.Big data’s role in smarter interactions and smarter users. Users save attention, time and money as a result of personalized and customized messages, which enable them to find the right tools to satisfy their needs quickly at the right cost. Creating these messages and products requires capabilities that the processing of Big Data can easily provide. This can involve the following types of analyses:1. User-environment analysis, in which information is collected about the environment where users interact with the product or service.2. User-profile analysis, whereby information is collected about consumers and their characteristics such as gender, age, likes and dislikes.3. User-interaction analysis, in which data is collected about users’ activities and behaviors as they interact with a product along the customer journey.4. User modeling, whereby data is collected and modeled to represent the behavior of a segment or cohort of users. The analyses and subsequent correlations are used to optimize the messages delivered to users according to their environment, profile and behavior patterns, as well as their stage in the customer journey.As users receive personalized messages and information that enable them to be smarter by helping them complete their tasks faster, more inexpensively and with less attention, the overall value realized from the product or service increases. This leads to higher productivity for the user, higher and sustained engagement with the product or service, a customer who feels smarter and, in the end, greater value for your enterprise.  Related: The Ultimate Test: Turning Your Cool Idea Into a Great Product Enroll Now for Freelast_img read more

Meet the College Students Who Are Driving the Future of Bitcoin

first_img Pangman is unmistakably impressed with everything Gardner and his peers have accomplished so far. “I feel like I’m a coach recruiting the national team for the Olympics,” he says. “And I found my star point guard.”He envisions the college clubs serving as feeder programs for the professional world of Bitcoin companies. The Bitcoin economy has a market cap of $5.8 billion, and last year startups in the space received nearly $100 million in venture capital in the U.S. alone.Related: The Secret Entrepreneurial Lessons of a Liberal Arts Education”Colleges are fantastic petri dishes for any kind of experiment,” says Pangman, who recently added Bloch and Gardner to the Bitcoin Foundation’s education committee. For his part, he’s waiting for the foundation’s board to approve a grant proposal he submitted that would fund a broad university outreach program. He wants to build a network of faculty, especially outside of the computer science and engineering departments where enthusiasm for Bitcoin might be expected. A peer-reviewed academic journal for cryptocurrency research, he says, “is in the offing as well.” 12 min read Bitcoin has filled that void. It is a technology that Gardner believes could lead to the betterment of millions of lives. As a global transaction network, it could be used for remittances — the practice of workers, usually recent immigrants, sending a portion of their pay back home to their families in another country. Remittances are a $550 billion industry, according to the World Bank. Established international money transmitters Western Union and MoneyGram charge fees as high as 10 percent for some amounts and destinations.Related: 50 Insane Facts About Bitcoin (Infographic)One the other hand, all-in-one Bitcoin companies like Coinbase offer the ability to buy and sell bitcoins for fiat currency, store them in a cloud-hosted wallet and send and receive them from others. At most, users pay a 1 percent fee for transactions. (A payments industry insider recently confided to me that legacy money transmitters like Western Union and MoneyGram are seriously concerned about Bitcoin.)”I think it’s an incredibly democratizing technology,” Gardner says. “All of a sudden, people who have come to America for the American Dream, and are trying to support their family back in Kenya, and are driving a taxi in New York, and who don’t want to give 9 percent of their hard-earned cash to Western Union — Bitcoin allows them to do that. That alone is a worthy cause for me to pursue.”But that potential wasn’t immediately apparent to Gardner. Like many people, he first heard of Bitcoin in connection with Silk Road, the online black market which the FBI shut down last fall and which has since been resurrected under new management. Curious, he visited the site and poked around, but didn’t buy anything. “Nothing I really want to get myself arrested for,” he thought.Related: How to Negotiate for What You WantBy the fall of 2013, however, some of Gardner’s more tech-savvy friends were telling him to buy bitcoins. He had doubts about its real value, but it sounded like easy money. His aunt had taught him the basic precepts of investing; he had been buying stocks for years. If Bitcoin was a bubble, it was one he could ride with a fair amount of confidence.Moreover, he began to be convinced that the shutdown of Silk Road that October would lead to a surge in Bitcoin’s value. He traded a few thousand dollars for bitcoins when the digital currency was worth about $140. He sold when the price went above $1,000.So far, so profit. But Gardner wasn’t willing to commit myself to understanding the technology behind this weird speculative commodity. Not yet. A major revolution BitcoinImage credit: zcopley via Flickr Opinions expressed by Entrepreneur contributors are their own. His tune changed when he transferred to the University of Michigan in January. His roommate, Kinnard Hockenhull, is involved in a Bitcoin startup, and the other man was thrilled to have a sounding board.Fired up by Hockenhull, Gardner began to read more about Bitcoin. The more he read, the more aware he became of its possible applications as a commodity, a currency and a transaction network. Meanwhile, he was obsessively reading Malcolm Gladwell’s book Outliers in advance of a scheduled Jan. 27 appearance by the author in Ann Arbor. He was particularly fascinated by Gladwell’s analysis of the fact that 14 of the richest people who ever lived were all Americans born within a nine-year period in the middle of the 19th century. Evidently they were born late enough to foresee the Industrial Revolution, the building of the railroads and the rise of Wall Street, but not so late that they weren’t able to capitalize on these events. A similar pattern emerged in the early days of the personal computer revolution, and again at the dawn of the commercial Internet.Related: How the World’s Richest Nations Are Regulating Bitcoin”Every single day, I would read this Gladwell chapter, and I would read a bit more about Bitcoin,” Gardner says.Finally, at 2 a.m. on the night before Gladwell was scheduled to speak, Gardner was struck with the realization that Bitcoin may represent yet another watershed moment. “Holy shit, this may be it,” he thought. “This is one of those major revolutions.”From that moment, he was hooked. He became active in the Bitcoin club at the University of Michigan, which is how he found himself on Feb. 5 on a videoconference call with Bloch, Elitzer and three other guys, members of the Bitcoin clubs at MIT and Stanford. Before long, they were agreeing to launch the CCN, with Michigan as its head chapter. Physical BitcoinImage credit: antanacoins via Flickr Since he was 11, Gardner has been determined to leave the world better than he found it. He grew up the sort of person on whom global warming weighs heavily. He had always assumed the future held for him a life of public service, a career in politics. The son of a leading expert in Confucianism, he discovered Sun Tzu’s The Art of War in high school and it came as a revelation.Things flowed naturally from there: At Bard College, where he was an honors student, he built his own major, political strategy — blending elements of political studies, economics, psychology and military strategy. For the last of these, he obtained special permission to take classes at West Point, the military academy.Related: Why College Students Need to Be Entrepreneurial With Their CareersIn the fall of 2013, he joined the campaign of Maura Healey, who was running for attorney general of Massachusetts. And that’s where his life plan went sideways. Although Gardner believed Healey was the best candidate and deserved to win, he soon became disgusted with the role of money in politics, with the sheer amount of time that has to be spent raising funds rather than shaping policy, and he left.For the first time in years, he didn’t know what the future held. “There was this void in my life, where I wondered how I was going to change the world,” he says.center_img The sky is the limit Bitcoin accepted hereImage credit: acroll via Flickr The network came out of stealth mode on March 25, announcing itself in a guest post for Bitcoin advocate Ryan Selkis’s email newsletter. “At the CCN, we plan to relentlessly promote the spread of Bitcoin and related technologies like a megachurch pastor on Sunday morning cable,” the founders wrote.The response from universities around the world has surprised even them. The network already counts some 16 established member clubs — among them Harvard and the University of Pennsylvania — with some two dozen more in the works, including clubs in China, Australia and Europe. The parent organization intends to provide “educational resources, administrative documents, marketing materials and regional contacts that might be needed for a college student to start a crypto club at their school,” Gardner and Bloch wrote in their March 25 announcement.Related: What Business Schools Don’t Teach Students But ShouldGardner is in the final stages of filing for 501(c)(3) status for the CCN, and he has decided on a big initiative for chapters in 2014: getting their universities to accept Bitcoin donations. There is a precedent: Earlier this year, Nicolas Cary, the chief executive of Blockchain, made a gift of $10,000 in bitcoins to the University of Puget Sound, his alma mater. But that was a one-time thing, Cary says, and he had a hell of a time making it happen. The school had no policy for handing digital currency gifts. In the end, administrators set up an account with BitPay, a payment processor, to accept the funds.Gardner already knows what such a process would look like at the University of Michigan. Donors would be able to make Bitcoin gifts in two ways: either through a Coinbase-powered widget on the Michigan site (if they had a Coinbase account), or by sending bitcoins directly from the digital wallet of their choice to the university’s own wallet address. The bitcoins in each transaction would be instantly converted into dollars in order to shield the university from Bitcoin’s infamous price volatility. Coinbase already provides this service for Overstock and other retailers.Before settling on Coinbase, Gardner spoke with representatives of BitPay and Circle. All three were interested, he says. “This could eventually lead to tuition payments and the like in Bitcoin, which would be massive. So there’s a lot on the line for them.” The betterment of millions Meanwhile, startups — including, quite possibly, some fostered by CCN clubs — will be working to make it possible to use Bitcoin, both the currency and the protocol, without understanding the underlying tech in all of its complexity. After all, how many casual smartphone users actually grasp the inner workings of the magic brick in their hand?If that can happen, the sky will be the limit for Bitcoin adoption. “In the short term it may not live up to the full hype, but in the long term, Bitcoin does for money and transactions what the Internet did for communication. It sets it free,” Elitzer says. “We can’t fully predict where that’s going to go. But you’ve got to respect its potential, at least, to change the world.”Related: Guess What: Going to College Still Pays If he is nervous about the upcoming meeting, Jeremy Gardner doesn’t show any sign of it.Today, Gardner and a friend, Daniel Bloch, will be sitting down with senior administrators in the development office at the University of Michigan to discuss what it would take to process university donations in Bitcoin. If the administration likes what they have to say, Michigan may soon become the first major university to accept Bitcoin gifts.Gardner, a 22-year-old junior and recent transfer from Bard College, is a co-founder with Bloch of the College Cryptocurrency Network, a burgeoning association of Bitcoin clubs on campuses nationwide. In its first weeks, the network has already attracted important mentors, among them Will Pangman, who sits on the education committee of the Bitcoin Foundation. Circle, a well-funded cryptocurrency startup, wants to be a corporate sponsor. The meeting this week in Ann Arbor will be an early milestone marking a whirlwind two months since CCN’s founding.It will also be a sign that the full impact of Bitcoin has yet to be felt; indeed, that entire user bases remain to be tapped. “People are calling Bitcoin the money of the Internet,” Gardner says. “I think it’s going to the Internet of money.”Related: IRS Will Tax Bitcoin, Says It’s Not CurrencyGardner isn’t alone in that thought. In fact, The Economist said as much in a recent issue. And despite some negative headlines this year, a growing number of investors are acting accordingly. Last month, Bitcoin startups Circle, Kraken and Xapo announced a combined $42 million in new funding. Venture capitalist Marc Andreessen pledged recently to invest hundreds of millions more in the Bitcoin space, on top of the $50 million his firm, Andreessen Horowitz, has already sunk in. Also last month, San Francisco-based hedge fund Pantera Capital announced the formation of a new $147 million fund for investments in digital currencies and related startups.But even as venture capitalists, institutional investors and hedge funds begin to pour Scrooge McDuckian sums of money into this nascent ecosystem, an even stronger indication that Bitcoin has a future may lie on college campuses.At first blush, student groups would seem a strange barometer of the future durability of a breakthrough technology. But think of how Facebook started at Harvard and spread to universities around the country, becoming a private club for college kids long before it opened up to everyone else. Then, too, think of which demographic propelled Snapchat to a multi-billion-dollar valuation.Related: 6 Bitcoin Basics for Beginners”The younger generation is always more open to adopting new technologies and new paradigms,” says Dan Elitzer, a first-year MBA student at the Massachusetts Institute of Technology and CCN’s regional director for New England. “If Bitcoin is going to be successful in the broader world, it’s going to be successful on college campuses earlier than we see it in most other communities.”For years, youthful enthusiasm for new technology has been translating into huge windfalls for entrepreneurs and savvy investors. Ironically, this means that the key to Bitcoin’s future may rest not with the investors themselves but with people like Jeremy Gardner. April 8, 2014last_img read more

Encryption on iPhones Facebook Apparently Petrified the NSA

first_img Hear from business owners and CEOs who went through a crippling business problem and came out the other side bigger and stronger. Stronger encryption in Apple’s iPhones and on websites like Facebook has “petrified” the U.S. government because it has made it harder to spy on communications, Glenn Greenwald, the writer who first reported on Edward Snowden’s stolen files, told CNBC.Former National Security Agency (NSA) contractor Edward Snowden caused major shockwaves around the world in 2013 when he unveiled the surveillance body’s wide ranging spying practices, which included regularly attempting to snoop of data held by major technology companies.Glenn Greenwald, the man who helped Snowden publish the documents, said that Silicon Valley companies have bolstered the encryption on their products, thereby making it harder for governments to eavesdrop.”They (Apple) are now starting to put serious encryption technologies in their new iPhones in their new releases and this has really petrified governments around the world,” Greenwald told CNBC in an interview at tech fair CeBIT in Germany.Apple, Google, Facebook and Yahoo are some of the major companies that have been in the spotlight after Snowden’s revelations. Information from the Snowden documents released earlier this month detailed how the CIA had been trying for a decade to crack the security in Apple’s products. And last year, Yahoo revealed that it was threatened with a $250,000 per day fine if it didn’t hand over data to the NSA.The tech giants have been taking major steps to make sure their communications are safe from spying, a move Greenwald – who won a Pulitzer prize for his reporting on the topic – said was motivated by the fear of losing customers rather than care for data privacy.”I don’t…(think) they suddenly care about privacy,” Greenwald said.”If…you’re a Facebook executive or an Apple executive, you’re extremely worried that the next generation of users…are going to be vulnerable to the pitch from Brazilian, and Korean and German social media companies where they advertise and say don’t use Facebook and Google because they’ll give your data to the NSA.” 2 min read Problem Solvers with Jason Feifer This story originally appeared on CNBC March 19, 2015 Listen Nowlast_img read more

first_imgOpera 46.0 is out: find out what is new by Martin Brinkmann on June 22, 2017 in Opera – Last Update: June 22, 2017 – 32 commentsOpera Software released Opera 46.0 on June 22, 1017 to the Stable channel brings along with it stability improvements and quality improvements.Opera states that the release  is the second stage of the Reborn project, a project to improve the look and feel of the Opera browser.Opera users can use the browser’s automatic update functionality to download and install the Opera 46.0 update, or download it directly from the Opera website.A click on Menu > About Opera runs a manual update check in the browser. If the new version is detected, it will be downloaded and installed automatically.Opera 46.0The first major release after Opera Reborn introduces a number of improvements, visually, usability-wise, and functionality-wise.The Speed Dial page, the New Tab Page of the Opera browser, received several improvements in the new Opera browser version.Users who use the dark theme without wallpapers will notice that Speed Dial itself is now dark as well. Opera Software cooperated with industry artists to bring a new set of custom wallpapers to the browser.You can set those with a click on the customize button on the Speed Dial page, and the selection of one of the available wallpapers there.Some backgrounds are animated, but there is no indication right now to highlight that in the selection menu.Opera 46.0 ships with stability improvements. According to Opera Software, Opera 46.0 will crash 35% less on average per user than the previous stable version Opera 45.0. This was achieved by fixing crashes, memory leaks, and glitches that impaired the user experience.Another new feature is support for animated PNG files. The format has risen to some prominence, largely thanks to Apple introducing the APNG format in iOS 10 iMessage applications. What’s particular interesting about this is that Opera Presto, used by the classic Opera 12 browser, supported the format already.Opera 46.0 uses Chromium 59 as its core. The new Chromium release introduced several new technologies, among them expensive background tabs throttling to improve battery life and browsing performance by limiting the access of background tabs to resources.Other improvements mentioned in the changelog:Videopopout support live videos nowNew View in Bookmarks option to Bookmarks pop up.If you import bookmarks from other browsers, those that were on the bookmarks toolbar of the source browser are now placed on Opera’s Bookmarks Toolbar as well.Bookmarks sync using Chromium’s sync protocol.opera://plugins redirects to opera://settings?section=plugins now.

first_imgVivaldi 2.0 Web Browser launches by Martin Brinkmann on September 26, 2018 in Internet – Last Update: September 26, 2018 – 53 commentsVivaldi Technologies AS launched the much anticipated Vivaldi 2.0 web browser on September 26, 2018 to the public.The third major release of Vivaldi after the initial beta version of the web browser and Vivaldi 1.0 in 2016 marks a new milestone for the company that is led by the former Opera CEO Jon von Tetzchner.Tip: We have updated our review of the Vivaldi web browser to reflect all recent changes up to version 2.0. In this guide, I’ll be looking at major features only.Vivaldi 2.0 is a milestone release especially if you compare it to version 1.0 released in 2016. The new version incorporates all the changes that updates introduced since 2016 and all the latest changes made to the browser since the release of version 1.15.While that means lots of new features and improvements, especially for users who don’t use version 1.15 or another recent version, it means that users who run a recent version of Vivaldi won’t see lots of changes when their version gets updated to version 2.0.Vivaldi 2.0Vivaldi 2.0 supports a large number of features and improvements that were not part of Vivaldi 1.0. Existing Vivaldi installations should pick up the update to version 2.0 automatically. Users can initiate a manual check for updates by selecting Vivaldi > Help > Check for updates.Downloads are also provided on the official website.Major new features and improvements include Sync functionality, the introduction of Delta updates, and new user interface and feature customization options.SyncVivaldi Technologies AS introduced Sync capabilities recently in the Vivaldi browser. Sync functionality was a much requested user feature next to a Mail client and mobile versions of Vivaldi. While the latter two have not been released yet, Sync is integrated.Sync is rather easy to set up in the Vivaldi browser. What you need to do is the following:Open the Vivaldi Sync settings by loading the following internal resource: vivaldi://settings/sync/. You may also click on the cloud icon in the status bar if it is displayed to open the resource directly.If you don’t have a Vivaldi account yet, select “Create an Account” and follow the instructions on-screen to create a new account.Type your Vivaldi username and password to log in and enable Sync functionality.Vivaldi users may sync a variety of data bits including passwords, bookmarks, settings, extensions, or notes. Sync in Vivaldi uses end-to-end encryption and no third-party servers.Customization ImprovementsCustomization is Vivaldi’s greatest strength in my opinion. It is a main distinguishing factor when compared to Chrome or Microsoft Edge, and even browsers that support a good degree of customization options as well such as Firefox or Opera.A look at the unique display of the Browsing History page is all that is needed to highlight that Vivaldi is different — and in a good way.The page displays a calendar, statistics and offers lots of useful options to users. Want to search across the entire history, display the pages of any given day, or check when you used the browser in a month? You can do that on that page and a lot more.Users who want just the core information get that as well. Just open the sidebar and select the History panel there to display the browsing history in the way all other browsers display it (chronologically).What else is new?Vivaldi’s Tab Tiling feature, which allows you to display multiple sites in a single tab, supports easy resizing of tiles now to adjust the size of any site displayed as a tile.Set the minimum width for the active tab in vivaldi://settings/tabs/New Welcome Page that acts as an introduction to Vivaldi and some of its features.Web Panels, the option to add any website as a panel in Vivaldi’s sidebar, may float now so that they are displayed on-top of the actual loaded webpage.New Window sidebar panel to improve tab management. Easy tab reordering using drag and drop, and tab loading.Notes sidebar panel supports markdown.Downloads sorting.Native screen capturing built-in.Custom Speed Dial thumbnails.Delta updates to reduce the size of updates and to deliver updates faster to users.Themes can be scheduled, e.g. switch to a dark theme at night and a light theme at day.Tab Cycling features a list viewer. Note that you need to enable the Tab Cycler and the list view mode by loading vivaldi://settings/tabs/.Here is a video that Vivaldi published to celebrate the launch of Vivaldi 2.0.Closing wordsThe Vivaldi web browser has come a long way since the release of the first preview version and first stable version in 2016.The team, as small as it is when you compare it to development teams of Firefox, Chrome, or Microsoft Edge, improved Vivaldi in numerous meaningful ways and managed to create a browser that is pleasantly different thanks to the wealth of personalization options and switches it supports.While there is certainly still work to be done, think mobile clients for a true cross-platform experience, Vivaldi is offering one of the greatest experience on the desktop already thanks to the browser’s huge list of customization options, personalization features, and other features that the team integrated natively.I’m already exited what the team has in Store for Vivaldi 3.0.Now You: What is your take on Vivaldi 2.0?SummaryArticle NameVivaldi 2.0 Web Browser launchesDescriptionVivaldi Technologies AS launched the much anticipated Vivaldi 2.0 web browser on September 26, 2018 to the public.Author Martin BrinkmannPublisher Ghacks Technology NewsLogo Advertisementlast_img read more
