Citation: ECOtality Inc. and car2go team up to bring charging infrastructure to San Diego (2011, July 14) retrieved 18 August 2019 from https://phys.org/news/2011-07-ecotality-car2go-team-infrastructure-san.html The program, which is being put into place in the San Diego metropolitan area, will consist of a fleet of about 300 smart fortwo electric drive vehicles, making it the largest single fleet of electric vehicles in the United States to date. There are expected to be roughly 1000 charging stations deployed in the metro area as part of the project. Jonathan Read, the CEO of ECOtality, had this to say about the project, “Innovative car-sharing programs like car2go’s service are pivotal to encouraging the mainstream adoption of electric vehicles. As we deploy approximately 1,000 Blink charging stations in the San Diego region as part of The EV Project, we are creating the robust public infrastructure necessary for car2go’s program to succeed. Together, we will show that EVs are a perfect fit for the lifestyle of San Diego drivers.”The project is expected to begin late in 2011. Data collected from this first city will be used to understand how consumers use electric vehicles and better understand charging patterns. This data will be used in the roll out of a larger scale program. At an undisclosed point in the future ECOtality hopes to be able to put out a network of 14,000 commercial and residential charging stations in 18 major cities in the United States. The project is partially funded by the U.S. Department of Energy through a federal stimulus grant as part of the American Recovery and Reinvestment Act.

EBay to power new data center with fuel cells Sean James, one of the authors, blogged earlier this week about the paper and Microsoft’s overall initiative. “Based on our models detailed in the paper,” he said, “we show how integrating a small generator with the IT hardware significantly cuts complexity by eliminating all the electrical distribution in the grid and data center.” James is senior research program manager, Global Foundation Services (the engine that powers Microsoft’s cloud services). The paper, he said, describes “how we are taking an unconventional approach to power a data center entirely by fuel cells integrated directly into the server racks.”The study, he remarked,” explores how to collapse the entire energy supply chain, from the power plant to the server motherboard, into the confines of a server single cabinet.” James cited key advantages of fuel cells, saying they are clean, reliable and well suited for small form-factor applications. While there is still a CO2 waste stream, the output is significantly lower and cleaner than other power generation technologies, he added. “In the new datacenter design approach outlined in our paper, chemical energy is first converted to direct current electrochemically and sent a few feet to the server power supply.” James also noted that the cost of fuel cells will drop as the fuel cell industry matures, especially small form factor fuel cells for automotive and IT applications.At this stage, however, he recognizes that such an initiative is not without challenges. “Deep technical issues remain, such as thermal cycling, fuel distribution systems, cell conductivity, power management, and safety training that needs to be further researched and solutions developed. But we are excited about working to resolve these challenges. This is only the early stages in our exploration of this concept.” Explore further Citation: Microsoft is exploring data centers powered by fuel cells (2013, November 15) retrieved 18 August 2019 from https://phys.org/news/2013-11-microsoft-exploring-centers-powered-fuel.html More information: www.globalfoundationservices.c … the-server-rack.aspxresearch.microsoft.com/pubs/203898/FCDC.pdf (Phys.org) —Fuel cell powered data centers may not be ready today but Microsoft is exploring the idea in a vision of data centers that one day can get out from under reliance on the electricity grid. Microsoft has released a paper discussing the fuel cell-based data center power distribution system. “No More Electrical Infrastructure: Towards Fuel Cell Powered Data Centers” is authored by Ana Carolina Riekstin, Sean James, Aman Kansal, Jie Liu, and Eric Peterson. The authors said that “If the FCs are placed close to power consumption units, at the servers or racks, we can completely eliminate the power distribution system in the data center, including the power backup generation system. So, no data center wide electrical infrastructure is required.” © 2013 Phys.org This document is subject to copyright.

The scientists, A. T. Costa, et al., from institutions in Brazil, Ireland, Singapore, and the US, have published their paper on graphene origami in a recent issue of EPL.”While bandgap opening and spin-polarized currents are two separate features contained in the wish list of every graphene researcher, we have identified a way that might tick both boxes at once,” coauthor Mauro Ferreira, Associate Professor at Trinity College Dublin, told Phys.org.Since the bandgap is an energy range where no electron states exist, opening a bandgap in graphene transforms it from a conducting material to a semiconducting material. Semiconducting graphene would be more useful, and could have particularly interesting applications for spintronics devices, which exploit the electron’s quantum mechanical property of spin in addition to its property of electric charge. One reason that graphene is a promising spintronics material is that, compared to other materials, it has an extremely small spin-orbit interaction (SOI). This means that its spin interacts very little with its orbital motion, and so spin dissipation is practically negligible in graphene. As a result, information stored in graphene’s spin can be retained for considerably longer times than in other materials. A small SOI also means that the information can travel over long distances with very little loss.Although a small SOI has many advantages, here the scientists wanted to increase the SOI in parts of graphene because doing so is necessary for opening a bandgap. Recent research has demonstrated that SOI is enhanced when graphene is mechanically bent. Here, the researchers theoretically showed that a 2D graphene sheet molded into periodic ridges and troughs has an enhanced SOI in the curved regions.Increasing the SOI is half of the process to inducing a bandgap; the other half is applying a magnetic field. As the researchers explain, the SOI and magnetic field complement each other in such a way that both quantities must be enhanced to induce a bandgap. The magnitude of the bandgap is ultimately determined by the smaller of these two quantities.One way that a magnetic field can be applied is by doping the graphene with magnetic atoms. Doping is also another way to enhance SOI, so the whole process could potentially be achieved by doping with the right adsorbants. This method has some advantages compared to previous attempts to open up a bandgap in graphene. So far, previous methods have failed to produce technologically relevant semiconducting graphene for several reasons, including that the bandgap size is too small and that disorder emerges into the system. The researchers here predict that the new method may overcome these difficulties and finally achieve useful semiconducting graphene.The second important effect of the new method—that it spin-polarizes the current—means that the electrons’ spins are aligned in the same direction. This feature is particularly important for engineering spintronics devices. In their current study, the researchers showed that the new process can be easily realized by depositing graphene sheets on a substrate with periodic trenches. In the future, they plan to perform measurements on the resulting graphene’s electrical properties. “While we have good experimental control on how the graphene sheets are folded, to measure the transport properties of such origami-like structures remains challenging,” Ferreira said. “The next step is to adapt some of the transport measurement techniques to deal with the structures in this new geometry.” Journal information: Europhysics Letters (EPL) © 2013 Phys.org.

In a new study, scientists have theoretically shown that a bandgap can be opened in graphene by folding 2D graphene sheets origami-style and exposing them to a magnetic field. In addition to opening up a bandgap, this method also produces spin-polarized current in the graphene sheets, making them attractive for spintronics applications.

In their paper published in Proceedings of the Royal Society B: Biological Sciences, the team describes how they captured over 500 of the snakes and tested them to determine how they survived being so long at sea without access to fresh water. Pelamis Platurus. Credit: Aloaiza/Wikipedia The yellow-bellied sea snake lives primarily in the sea, which means it has to get all of its food and water from the ocean. The problem is, unlike sea turtles, it doesn’t have the ability to simply drink sea water and filter out all the salt. Instead, it survives, the researchers in this new effort report, by not drinking at all for months at a time. Living as it does off the coast of Costa Rica, the snake is dependent on fresh water from rainfall, but only during the rainy season—the fresh water sits for a time atop the heavier saltwater below, the snake surfaces and swallows it, bloats up and then doesn’t have to drink again for months. The trick is in surviving severe dehydration—the team found some specimens lost up to 18 percent of their body mass while waiting for rain.The researchers discovered this unique ability by capturing and examining specimens in their labs, caught at different times of the year. To test for thirstiness, the snakes were put in fresh water tanks. To assess how much water they were storing, several were weighed, then killed and baked in ovens to remove all the water held inside them, then weighed again. Some were also dissected.The researchers found that the snakes do have some ability to eliminate salt—small glands around their tongues expel salt taken in during eating, or to remove some salt from the fish they eat. The glands were nowhere near efficient enough to allow the snakes to drink saltwater however, thus, their refusal to do so. They also found that the snakes’ skin prevented salt from being absorbed into their bodies.The researchers also noted that the snakes’ technique for surviving at sea makes it particularly vulnerable to changes in its environment such as less frequent rainfall. This, they suggest might reveal why it is that scientists have been finding that sea snake populations are declining as global warming causes changes to rain patterns across the globe.

Here, we demonstrate a paradigm shift for the widely distributed pelagic sea snake, Hydrophis (Pelamis) platurus, which dehydrates at sea and spends a significant part of its life in a dehydrated state corresponding to seasonal drought. Snakes that are captured following prolonged periods without rainfall have lower body water content, lower body condition and increased tendencies to drink fresh water than do snakes that are captured following seasonal periods of high rainfall. These animals do not drink seawater and must rehydrate by drinking from a freshwater lens that forms on the ocean surface during heavy precipitation. The new data based on field studies indicate unequivocally that this marine vertebrate dehydrates at sea where individuals may live in a dehydrated state for possibly six to seven months at a time. This information provides new insights for understanding water requirements of sea snakes, reasons for recent declines and extinctions of sea snakes and more accurate prediction for how changing patterns of precipitation might affect these and other secondarily marine vertebrates living in tropical oceans.
(Phys.org) —Although organic materials are often used as semiconductors, such as in organic LEDs and organic transistors, organic materials that have an electrical conductivity as high as that of metals are still very scarce. One problem with developing organic metals is that there is a tradeoff in terms of their crystalline structure: a high crystallinity is required for high conductivity, but is detrimental to the materials’ processability.

Armao, IV, et al., at the University of Strasbourg in France, have demonstrated a way to overcome this problem by developing a new class of organic materials that are highly conductive yet very soft and flexible. When irradiated with a light pulse, the material reorganizes its molecules to correct structural defects. The new material can therefore be assembled with low crystallinity and then transformed via a light pulse into a material with high electrical conductivity.”Historically, electronic devices have been developed with inorganic materials such as doped silicon, copper, silver, etc.,” Nicolas Giuseppone, professor at the University of Strasbourg, told Phys.org. “These materials come from limited natural resources which are expensive to extract and process before even being suitable for manufacturing. Additionally, a big problem we have is electronic waste, as many of the inorganic materials used in electronics are quite toxic for the environment, and recycling these materials is difficult and expensive. Organic metals provide an alternative material which is cheaper, easier to produce, and environmentally friendly. In addition to replacing inorganic materials in the electronic devices we currently use, we may be able to create devices with novel properties and architectures through a combination of synthetic modification (at the molecular level) as well as control over the supramolecular organization (at the bulk level).”The new material is a one-dimensional supramolecular polymer composed of stacks of molecular units called tris-amide triarylamines (TATA). Although these organic nanowires may originally suffer from the same structural defects as other organic materials, the application of a relatively low-energy light pulse can correct misalignments of the TATA stacks, essentially giving the polymers the ability to self-heal. The results showed that light irradiation increased the conductivities of the suparmolecular polymers by up to four orders of magnitude, reflecting the effectiveness of the photoinduced supramolecular self-optimization. The study marks the first demonstration of supramolecular polymers that achieve electronic, magnetic, and optical signatures similar to those measured in the best conjugated polymers. “I would say the greatest significance is (a) the ability to demonstrate metallic properties in a supramolecular system without the need to crystallize the material or resort to other processing techniques, (b) the demonstration that supramolecular systems, i.e. ensembles of molecules which are non-covalently bound, can possess characteristics found in conjugated polymers, (c) the ability to remotely trigger the healing mechanism and doping process with light, which creates a responsive material, and (d) the demonstration of a novel error correction mechanism driven by supramolecular polaron diffusion (charge-transfer interactions) within the assembled structures,” Giuseppone said.Highly conductive organic metals could have a variety of novel applications in organic electronics due to their advantages of being lightweight, low cost, and disposable. Applications include transparent electrodes, printed electronic circuits, thermoelectric materials, and memory devices. “Future research plans include both applications of these materials in devices as well as further research into their fundamental properties,” Giuseppone said. “In terms of applications, we are working towards incorporation of these organic assemblies as metallic interconnects for electronic circuitry, testing the efficacy of these materials in solar cells as well as trying to develop means for controlled vertical device architecture. Our fundamental work involves manipulation of optical and plasmonic fields as well as further elucidation and control over the conduction properties.” (b-d) Images of the organic metal, TATA, are shown with different imaging techniques.

How a change in slope affects lava flows (Phys.org)—A team of researchers with Dresden University of Technology in Germany has apparently solved the riddle of why lava sometimes forms into hexagonal towers as it cools. In their paper published in Physical Review Letters, the team describes how they put together a computer model that ultimately showed how such shapes can form. © 2015 Phys.org Citation: Computer model solves the riddle of why lava sometimes forms into hexagons (2015, October 14) retrieved 18 August 2019 from https://phys.org/news/2015-10-riddle-lava-hexagons.html Scientists and other people have been amused, piqued and inspired by some of the geometric shapes that come about as lava cools—Devils Tower in Wyoming, for example, or Giant’s Causeway in Northern Ireland, both feature cooled lava in the form of hexagonal structures. Upon seeing them, most wonder how they could have come about—after all, most things in nature are random, or perhaps round. Hexagons seem like they could come about only due to intervention by us humans. Now it appears, the team in Germany has cracked the riddle of how nature could have made it happen.It is all about heat differential and the way cracks form, the team reports. They made these discoveries by building a model very similar to those used by engineers to build bridges or aircraft parts. It allowed them to account for the characteristics of the lava, both when it was hot, and as it cooled. That allowed them to see that after some bit of lava stopped flowing, as it cooled, the inner parts cooled faster than the outer parts, leading to shrinkage and the formation of cracks adjacent to one another, which meant they formed at 90 degree angles. Then as the lava cooled even more and more shrinkage occurred, the cracks made their way down into the lava below which was still solidifying—that forced the cracks to grow larger, forcing the angle between them to change to approximately 120 degrees, which occurred because it was the point at which the largest amount of energy was released—and it is also, of course, the same angle degree found in hexagonal structures.The hexagonal structure were then maintained as the lava cooled down to ambient temperatures and the shape was persevered—meanwhile, the same process occurred around it, causing the creation of other lava formations that looked very nearly just like it.

Lett. 115, 154301 – Published 7 October 2015. dx.doi.org/10.1103/PhysRevLett.115.154301ABSTRACTBasalt columns with their preferably hexagonal cross sections are a fascinating example of pattern formation by crack propagation. Junctions of three propagating crack faces rearrange such that the initial right angles between them tend to approach 120°, which enables the cracks to form a pattern of regular hexagons. To promote understanding of the path on which the ideal configuration can be reached, two periodically repeatable models are presented here involving linear elastic fracture mechanics and applying the principle of maximum energy release rate. They describe the evolution of the crack pattern as a transition from rectangular start configuration to the hexagonal pattern. This is done analytically and by means of three-dimensional finite element simulation. The latter technique reproduces the curved crack path involved in this transition.

Taking turns to respond to each other is a key part of conversation and babies learn the technique at around six months of age, long before infants know much about language, says a new study.The speed of response white taking turns — about 200 milliseconds on average, about the same time as it takes to blink — is astonishing when we appreciate the slow nature of language encoding: it takes 600ms or more to prepare a word for delivery, the study said. Also Read – ‘Playing Jojo was emotionally exhausting’This implies a substantial overlap between listening to the current speaker and preparing our own response. In human infants, turn-taking is found in the ‘proto-conversations’ with caretakers.These infant-caretaker interactions are initially adult-like in terms of how fast infants can respond. But as they develop into more sophisticated communicators, infants’ turn-taking abilities slow down, likely due to both learning more and more complex linguistic structures, and having to find a way to squeeze these into short turns, said researcher Stephen Levinson from Max Planck Institute for Psycholinguistics in the Netherlands. Levinson reviewed new research on turn-taking, focusing on its implications for how languages are structured and for how language and communication evolved. Also Read – Leslie doing new comedy special with NetflixHe pointed out that turn-taking is common not only across unrelated cultures and language, the patter is also exhibited in all the major branches of the primate family – partly innate and partly learned in some monkeys, just as with human infants. Even our nearest cousins the great apes take alternating turns in gestural communication, despite having a less complex vocal channel. All of this suggests that humans may have inherited a primate turn-taking system, Levinson said.This may have started out as a gestural form of communication, as with the other great apes, then later (about one million years ago) became one primarily expressed through the vocal channel, the study noted. The findings appeared in the journal Trends in Cognitive Sciences.
In view of fostering the uniqueness of Indian art and culture, the Legends of India – a non-profit organisation takes the privilege of organising ‘Baithak’, which will induce a direct interactive session with Ustad Aashish Khan and spectators.

This April, love will linger in the erotic colours of charming bodies when Ramli Ibrahim, a celebrated Malaysia dancer and Odissi exponent will perform a unique contemporary Odissi presentation at Kamani auditorium on April 6 at 7 pm. ‘Amorous Delight: A case of possession by love’, organised by Shriram Bharatiya Kala Kendra and Sutra Foundation depicts the delight and frustrations, the sensuous charms and mad intoxication, the anguish of union-separation of the complex gamut of the sense of belonging and not belonging, found in this human obsession, called Love, in an intense poetic language of the body. Also Read – Add new books to your shelf With dance composition and artistic direction by Meera Das and Ramli Ibrahim – Amorous Delight – derives its inspiration from ‘Amarushataka’, the ninth century anthology of hundred Sanskrit couplets, all based on ‘shringara rasa’ in which love lingers in the erotic contours of charming bodies. The ‘Amarushataka’ had been illustrated by Indian chitrakars (traditional painters) over centuries from different parts of India. The visual images rendered in palm-leaf (pothi) of the medieval ‘Sharanakula’ palm leaf master (his name was never known) of Nayagarh district, Odisha, were some of the most beautiful and artistic of these rare illustrations. Also Read – Over 2 hours screen time daily will make your kids impulsiveShobha Deepak Singh, Director, Shriram Bharatiya Kala Kendra, says, “The work is refreshingly different and sufficiently ‘controversial’ to tickle everyone’s senses and curiosity. The focus is on the ability of the dancers to impart a sensuous atmosphere evoking the subtle nuances of love and its many splendored settings. The work is contemporary within the matrix of traditional subject matter and Odissi.”What makes this staging particularly exciting is the added creative input of Dato’ Sri Bernard Chandran, Malaysia’s fashion mogul and designer to the region’s celebrities, royalty and high society mavens, who will be giving the production an alluring new look in terms of its costume design. The lighting design by Sivarajah Natarajan invites the audience to a ravishing visual feast of the highest order. As a teacher of Bharatanatyam and Odissi, Ramli has groomed some of the finest dancers, who have emerged from Malaysia and at the same time placed Indian classical dance in the context of the Malaysian experience. As Artistic Director of Sutra Dance Theatre, which he started in 1983, Ramli Ibrahim has always envisioned his creativity as a holistic universal experience, one that transcends all cultural boundaries. Says Ramli Ibrahim, “True to the spirit of creativity, ‘Amorous Delight’ points to a creative eclectic future while reflecting (but not absconding from) the past. The intimate, intense and timeless visions of love have continually inspired painters to express themselves in literature, visual and performing arts since ancient times.” With no systematic story-line of the lover and the beloved; in each rendition, the verses of Amarushataka allude to new images of the pleasures and sorrows of love in its multitude of shades and settings. Each lyrical poem, complete in itself, enshrines in cameo-like images of various fleeting emotions, moods and attitudes, couched in language and imagery, which conjure up magical voluptuous beauty and charm.
The age at which a young woman experiences her first menstruation is associated with the age at which her son experiences puberty, according to a latest research.While it has been known for some time that mothers’ age at puberty is associated with their daughters’, much less was known about the link with their sons’ age at puberty. The findings, published in the journal Human Reproduction, suggested that mothers who reported having their first menstrual bleed earlier than their peers had sons with signs of puberty starting earlier than their peers.

For every occasion, picking the perfect ensemble with jewellery and make-up that accentuates the outfit is they key to stand out. Experts give some tips: Pair busy patterns with subdued jewellery: If the outfit has a busy print or textures, ensure that it is paired with simple jewellery. Solid watches, earrings and bracelets go a long way. The focus should be on simplicity – a small pendant, diamond studs, and a simple bracelet is enough to make an outfit look complete. Also Read – Add new books to your shelfHighlight your face with statement earrings: Match your earrings to your face shape and put on a pair of statement earrings to bring out your best facial features. For example, women with heart-shaped faces should consider earrings that are wider at the bottom for a balanced look. If your face has an oval shape, triangular earrings and studs will showcase your cheekbones. Illuminate your skin tone with jewellery that complements it: Gold tones go well with darker hair, while silver illuminates most natural tones. White gold and gems that are purple, blue and red pair nicely with cooler skin tones. Warmer skin tones go well with orange, yellow and green gemstones, as well as with yellow metals. Also Read – Over 2 hours screen time daily will make your kids impulsiveColour coordination: For a complete look, it is imperative to coordinate the colour of the jewellery pieces based on the outfit. White pearls match well with blue and green outfits. Purple clothes should be paired with green emeralds or gold-toned jewellery. Diamonds can be coordinated with any look, and black jewellery makes a neutral outfit look spectacular. Make your eyes pop: If there’s a time to get over your fear of colourful eye shadows and eyeliners, it is now. They sound intimidating but are actually really easy to use. Switch your trusted black winged liner with a coloured one or add a pop of colour in the inner corners of the eye. If you really want to make a statement, use a bright colour under the bottom lash line. Build up your mascara: Build up coats of mascara to get the right amount of volume on your lashes. It’s the easiest way to fake the false eyelash look. Always curl your lashes before applying mascara. If you’re feeling particularly colourful this festive season, try coloured mascara with a matching eyeshadow. Add flush to your cheeks: To make your face look vibrant and fresh, use a generous amount of blush. Cheek tints are the best way to add that dewy glow, but if you want more saturated colour, layer it with a powder blush and set. Add highlighter for the glow: Sweep the right amount of highlighter on to the high points of your face to give you that radiant glow. The right shade of highlighter depends on your skin tone. If your skin tone is deep, use a gold highlighter, and if your skin tone is light, use a pearly gold or pink highlighter. Make a statement with your lip colour: Festivals are the perfect occasions to make a statement with luscious lip colours. Pick up bright reds and pinks and go bold. Top it up with a metallic or shimmery gloss for fresh and pouty lips.
Regardless of the confusion surrounding when the Strong firing will happen, there’s little doubt that he’s done in Austin, even with a pricey $10 million contract buyout in place.Jim Harbaugh and Urban Meyer ruined it for everyone. Harbaugh and Meyer’s overnight Houdini turnaround jobs at Michigan and Ohio State have severely shortened the patience level, and raised the expectations of major programs mired in downturns and mediocrity. Patience is a word that no longer exists in the modern college football vernacular.Charlie Strong seems like a genuinely nice, likeable person, and a great mentor. No matter how nice and likeable you are, at a program like Texas, winning is all that matters. The Longhorns are 5-6 on the year, and Strong’s 16-20 record in three seasons as head coach just isn’t good enough.If Strong is fired, the logical choice to replace him would appear to be Houston head coach Tom Herman, who will be the hottest offseason college football coaching commodity since his mentor Urban Meyer left Utah. The rumor mill is already violently swirling.Herman has Texas recruiting ties, and would inherit several of Strong’s highly ranked recruiting classes. The pieces are in place to win immediately in Austin. He better. Ask Charlie Strong what happens if you don’t. Charlie Strong’s tenure as head coach of the Texas Longhorns was already on life support. Saturday’s embarrassing 24-21 loss to 2-9 Kansas, and the sight of goalposts meeting their demise in Lawrence, should be enough to force Texas to pull the plug on the Strong era. Advertisement The timing of that decision has been a source of confusion, largely thanks to “reports” with “sources” on Twitter that stated Texas had fired Strong immediately following the game. According college football insiders Pat Forde and Bruce Feldman, the Twitter reports of his firing are inaccurate. Shocking, Twitter was wrong.I’m told report of Charlie Strong already being fired is not accurate. Those conversations have not been had at this point, per source.— Bruce Feldman (@BruceFeldmanCFB) November 20, 2016 I am told by multiple sources this report is incorrect. Strong has not been fired. Tomorrow is another day, of course, but not now. https://t.co/0eRT6hQwpD— Pat Forde (@YahooForde) November 20, 2016

Mastodon makes music as powerful, as intimidating and as heavy as the prehistoric beast that lends the group its name. Formed in Atlanta in 1999, Mastodon–lead guitarist/vocalist Brent Hinds, drummer/vocalist Brann Dailor, bassist/vocalist Troy Sanders and guitarist Bill Kelliher–is at the forefront of a generation of bands expanding heavy metal beyond its headbanging roots into new realms of sonic complexity and thematic daring.With the recording industry now a lumbering dinosaur facing extinction of its own, Mastodon’s most recent album, 2011’s The Hunter, extends the quartet’s high-concept sensibilities beyond the music–their 2004 album, Leviathan, drew inspiration from the novel Moby-Dick, while 2009’s Crack the Skye charted the adventures of a quadriplegic hero who learns the art of astral projection–into its packaging. The move is intended to steer fans away from simply downloading or sharing digital files and instead purchasing the vinyl or CD release.Related: Three Key Business Investments to Make in 2012″For a band like Mastodon, a lot of fans want something extra–it’s up to the labels and up to the bands to figure out new and exciting ways for them to want to purchase the music,” Dailor says.Mastodon commissioned artist A.J. Fosik to create a sculpture depicting the head of a mythical, bull-like creature for The Hunter’s cover art, then teamed with Paris-based Total Immersion, an Augmented Reality (AR) software and solutions developer with offices in Los Angeles, to build an interactive 3-D experience that uses the listener’s smartphone or computer camera to transpose the sculpture’s head over their own, mirroring their movements in real time.”We’re always keen on doing something innovative–we like to go as far as we can,” Dailor says. “We knew [AR] was something new and different. It had the potential to be cool, but we weren’t sure how to implement it. In the end, it was an obvious choice to make the Hunter head the head of a person. It was the coolest thing we could do.”Related: Seven Essential Apps for Your Sales TeamAR technologies can do a lot of cool things, especially for small businesses. AR-based mobile applications essentially translate the digital experience to the offline world, overlaying contextual information on top of live video streams. For example, a shopper could enter a brick-and-mortar retailer, hold their phone in front of an item and access location-specific product details, prices, store discounts and customer reviews. Consumers could even “try on” the latest fashions or watch step-by-step instructional videos on how to install a new appliance.”AR can transform passive consumers into active consumers,” says Total Immersion co-founder and CEO Bruno Uzzan. “It has the potential to disrupt any kind of market.”In addition to Mastodon, Total Immersion has worked on AR development projects for clients such as Paramount Pictures, Cartoon Network and Dior. The startup also offers a suite of licensed D’Fusion solutions that enable software developers to build their own AR experiences for smartphones, tablets, PCs and even connected TVs; its D’Fusion Mobile product touts a 3-D rendering engine and facial recognition tools optimized for next-level mobile commerce experiences.Related: The Best iPhone Apps for Business Productivity”It’s a no-brainer that AR will be used in many activities,” Uzzan says. “This is where the world is going.”Total Immersion’s innovations certainly struck a chord with Mastodon. “Nobody else has done anything like this, and it ended up being cheaper than a lot of the hands-on, tangible promotional ideas we were discussing,” Dailor says. “We’re excited to be a part of [AR] and we’re looking forward to seeing where it goes from here. I hope more bands pick up on it–that’s the only way it will grow. But it’s cool to be the first.” This story appears in the January 2012 issue of .

Email marketing can help businesses keep in touch with customers and prospects. But there’s a big difference between simply adding people to your contacts list and running a savvy campaign that drives traffic to your website and generates sales.Here are some tips to help you maximize the power of your email marketing:1. Split test your opt-in forms.Split testing can be a powerful tool in the online marketer’s arsenal. You can test different variables on your website and in your marketing campaigns to determine which combinations will generate the most email subscriptions.For example, if you can’t decide where to place your opt-in form on your website, or what color to use for your “Sign Up Now” button, a split test can pit various choices against each other and determine a statistically significant winner.To get started with split testing, consult your email management program’s help section. Most top-tier list management programs — including Aweber, MailChimp, iContact and ConstantContact — offer split testing as a default function.Related: What’s Hot and What’s Not in Content Marketing2. Split test broadcast messages.Your “broadcast messages” also can be useful candidates for split testing. These are the messages you send spontaneously, unlike scheduled follow-up emails that go out at a set time.Because broadcast messages usually announce timely information such as product launches and sales promotions, it can be important to make them as effective as possible. Consider split testing both the subject line and call to action in your broadcast messages.Even small improvements in open and click-through rates can make a significant difference in the ROI for your email marketing.Related: What You Need to Know About YouTube’s New Analytics Program3. Survey your customers.One of the greatest benefits of having customers’ email addresses is the market research potential. For example, if you’re trying to decide whether to stock Brand X or Brand Y, you don’t need to rely on gut instinct. Set up a survey and use email to ask customers for their feedback. You also can gather demographic data about them through these surveys.4. Help now and sell later.Too many people approach email marketing as yet another opportunity to make their sales pitch. But that’s often a shortsighted view.Instead, use your email messages to provide helpful information and deepen your customer relationships. As customers come to rely on you as an industry expert, you will likely see a corresponding increase in sales.5. Segment your lists.When composing a marketing message, which do you think will be more effective: a one-size-fits-all pitch that promotes the same product regardless of the customer’s purchase history? Or one that offers promotions for products the customer bought most recently?The better you can tailor your email marketing messages to specific customers, the more effective your promotions will likely be. The key lies in email list segments — groups of subscribers who have a certain characteristic in common. For example, you could create segments for subscribers who have spent a certain amount of money with your company, or who open every single message you send.The specific segments that work best will vary by business and industry. But by experimenting with different types of segmenting and targeting, you can make your messages more interesting and relevant to subscribers and, consequently, more likely to result in sales.Related: Chris Brogan on Cultivating Visibility6. Regularly scrub your lists. Email list subscribers who no longer open your messages are wasting your time and money. Because most list management programs bill by the number of email addresses, it’s important to take time each month to “scrub” your list and remove people you’ve fallen out of touch with.You can use the search function in your email management program to identify subscribers who haven’t opened a message in a given period of time, such as the last two months, and who were added to your list before that “scrub” time. Keeping your list clean will help ensure that it’s as effective as possible. Opinions expressed by Entrepreneur contributors are their own.

Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Opinions expressed by Entrepreneur contributors are their own. The power of big data is enormous, but so is the stress of trying to tap it for all it’s worth. We now produce data in staggering amounts, and marketers aren’t always sure what to do with it or how to sift through the resulting mass of information.Visual.ly, a self-described marketplace for visual content, has created an infographic with McKinsey that shows marketers can harness big data to increase the effectiveness of their campaigns and improve their companies’ bottom lines. That’s good news because, as the infographic reports, 72 percent of chief executives say marketers are rarely able to explain how much business the money they spend will generate.Related: IBM to Open Up Jeopardy Winner Watson’s ‘Brain’ for EveryoneConsumers today produce most of the data that marketers need. For example, 42 percent of European consumers conduct web searches on their mobile devices while shopping in brick-and-mortar stores. And 61 percent of consumers worldwide use digital tools as part of their “purchase journey” — whether it be for research, comparison shopping, buying, reviewing or discussing their purchase on social media after the fact. A 10-year study of companies across multiple industries showed that harnessing this data led to a 5 percent increase in productivity and a 6 percent increase in profits.But there’s a long way to go. In a survey, chief marketing officers said 63 percent of projects do not use marketing analytics to inform decisions.Check out the infographic below and stay ahead of the pack.Click to Enlarge+ 2 min read November 21, 2013 Growing a business sometimes requires thinking outside the box.

Register Now » Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals The synchronized ballet of traffic light adjustments that turned Los Angeles into a parking lot, helping Mark Wahlberg and Charlize Theron escape with an armored truck full of cash in The Italian Job, is no longer the stuff of Hollywood legend.The tech behind it is already rolling on the installation trucks of companies like Silver Spring Networks, which is snapping up municipal contracts from Copenhagen to California, installing smart street lights and utility meters that beam data back to headquarters, enabling energy savings and reducing costs.The 15-year-old company is using a planned community under construction near Denver to demonstrate how a smart street light network can do everything from offering free Wi-Fi to alerting motorists when a parking space opens up. Theoretically, the lights could be the target of an Italian Job-style hack, too, but that’s not likely, according to Silver Spring CEO Mike Bell.”We take a common sense approach to security,” he said in an interview at CES on Wednesday. There are 25 million Silver Spring sensors all over the world, and their military-grade security standards offer a good starting point, although Bell acknowledged that the security practices of some municipalities and other partners are sometimes deficient.”From a public good perspective, our devices offer the minimum level of security you should have,” he said. In other words, it’s more likely that a breach would occur in the network of a utility company or local government than as a result of a lone hacker roaming the streets with a laptop.Those weak links, among many other reasons, is why “it’s always easier if you’re in first,” according to Bell. The company has seen success in Paris, where every street light uses its sensors, and New York City, where Con Edison is about to replace all of its customers’ existing gas and electricity meters with smart ones. But communities engineered from the ground up for secure connected devices, like the planned Pena Station near the Denver airport, will be a crucial proving ground.Pena’s street lights will have controllable smart LED lights, offer Wi-Fi access, sense temperature and air quality and use cameras for public safety and parking management. If a bulb is about to burn out, the city will automatically be notified, eliminating costly inspections. Assuming all goes well, the lights will expand across Denver via a partnership between Silver Spring and Panasonic. Part of what makes Silver Spring’s expansion easier than, say, the rollout of 5G is that its sensors communicate on unlicensed radio spectrum. That means no waiting for spectrum auctions, a nice benefit during tumultuous times for the Federal Communications Commission.As for Los Angeles, though, Silver Spring likely won’t be expanding there: the city already signed a contract for smart streetlights with Philips. 3 min read

This story originally appeared on PCMag 2 min read Elon Musk is at it again this week with news of yet another business venture in yet another futuristic field of research. He’s given us electric cars, a company dedicated to space exploration, is working on clean energy tech and is building a tunnel, but now he wants to connect our brains directly with computers.Musk’s latest venture is called Neuralink. It’s a medical research company whose technology is called “neural lace.” Very few details are known, but according to The Wall Street Journal, neural lace will allow individuals to directly communicate with a computer without the need for a physical interface.Long Neuralink piece coming out on @waitbutwhy in about a week. Difficult to dedicate the time, but existential risk is too high not to.— Elon Musk (@elonmusk) March 28, 2017As Musk’s tweet suggests, we’re set to hear a lot more about Neuralink next week from the website Wait But Why.The new venture is being privately funded by Musk and hopes to perfect neural lace for use by humans. What it boils down to is a series of electrodes implanted in our brain which then allows a wireless link to computers. Thoughts, and therefore information, can then be uploaded and downloaded as desired. It’s a process Business Insider describes as allowing “humans to achieve higher levels of cognitive function,” and it would act like an AI layer within our brains.It sounds as though neural lace would allow for the quick uploading of new information without the need to learn it (just like in The Matrix, but without the physical link in your neck!). Achieving that also means figuring out how our brains store information so as to upload it in the correct format.One key question that will hopefully get answered next week is: how many years will we be waiting to have neural lace installed? Are we talking less than a decade or multiple decades? Register Now » Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals
