According to FootPath’s company, Path Intelligence, based in Portsmouth in the UK, the technology is able to locate a person’s position to within a few meters. The antennas capture the unique identification number of the shopper’s phone. The data is fed to a processing center where the data is audited and undergoes statistical analysis. The shopper-flow information is continuously updated At any time, shopping center management can access the data via the Path Intelligence web-based reporting system. Retailers and mall management have long been excited about capturing drill-down data to support decisions about optimal inventory, position in the mall, staffing, and customer demographics. For the industry, this is one more survival data tool. For mall management, knowing more about their shopper traffic is their lifeblood. People’s patterns of movement can give them a better opportunity to profit and keep drawing in traffic by ensuring a better so-called “shopping experience.” They are eager to know if shoppers from store A go to store B, and how long a shopper remains in any one store. They also get a handle on which stores are being ignored altogether.Management at both malls say that personal data is not at risk, as personal data is not tracked. Signs posted around the malls will give visitors the opportunity to shut off their phones.Sucharita Mulpuru, retail analyst at Forrester Research, has said that as more retailers move to roll out this kind of technology, the scenario will have to be for them to ask customers to opt in, not opt out. In retail stores, counting people has already been in use through the implementation of various technologies such as infrared beams, computer vision and thermal imaging. Path Intelligence launched with the idea of bringing online analytics to the offline world. The company wanted to close the information gap about offline customer movements. They sought to provide retail clients with a richer level of information so that they were not just getting people counts but also retail analysis.

Molecules on a string, and why size isn’t the only thing that matters for data storage Explore further (Phys.org) — One of the more frustrating problems in studying space and the universe is the fact that it’s made up of mostly hydrogen molecules that in the cold confines of space, are impossible to see. Perhaps even more frustrating is that researchers have known for some time that if they could get a handle on H2-CO molecules, they could very well get a better idea of how hydrogen molecules are organized because they come about when the two elementary molecules interact. Unfortunately, because the spin or rotation existent in such molecules is greater than the vibration produced by its components, the spectral images produced have been very nearly impossible to decipher. Now however, a team of researchers has figured out a way to interpret such images using sophisticated computer calculations and have written a paper describing their results and have had it published in the journal Science. Citation: Shedding light on an interstellar gas: Researchers derive theoretical spectrum of H2-CO (2012, June 15) retrieved 18 August 2019 from https://phys.org/news/2012-06-interstellar-gas-derive-theoretical-spectrum.html More information: Theory Untangles the High-Resolution Infrared Spectrum of the ortho-H2-CO van der Waals Complex, Science 1 June 2012: Vol. 336 no. 6085 pp. 1147-1150. DOI: 10.1126/science.1221000ABSTRACTRovibrational spectroscopy of molecules boasts extremely high precision, but its usefulness relies on the assignment of spectral features to corresponding quantum mechanical transitions. In the case of ortho-H2-CO, a weakly bound complex abundant in the interstellar medium (although not yet observed there), the rather complex spectrum has been unexplained for more than a decade. We assigned this spectrum by comparison with a purely ab initio calculation. For most lines, agreement to within 0.01 centimeter−1 between experiment and theory was achieved. Our results show that the applicability of rovibrational spectroscopy can be extended with the assistance of high-accuracy quantum mechanical computations. © 2012 Phys.Org H2-CO molecules come about when hydrogen molecules (H2) and carbon monoxide molecules (CO) interact; past researchers have found that their interaction is weak, with the resulting molecule acting more like a duel molecule than a separate new one. Once the two molecules combine they wind up with one of two kinds of spin around the two nuclei: aligned in the same direction, known as an “ortho” state, or not, known as a “para” state. The new molecule also has an internal vibration of course. In this new research, the team studied H2-CO molecules in their “ortho” state because more of them are generally seen in space.What intrigues space researchers though is evidence that H2-CO molecules come about in space when the two elementary molecules meet, which by inference would lead scientists to the H2 that they actually want to study.Sadly, trying to decipher the spectral signature of H2-CO has been stymied by the fact that such molecules have the peculiar property of having their vibrations overrun their spin, which is what researchers look for when studying imagery from space. Because of this, researchers have not been able to use H2-CO to study just H2. Now however, it appears that work by a team of researchers using sophisticated calculations on a computer to find the precise quantum mechanical alterations that each atom in the new molecule has undergone, has resulted in findings that match the properties of H2-CO, thereby giving researchers a better picture of how vibration and spin work within the molecules, which, by extension, should give researchers studying the far reaches of space a much better idea of what to look for.

(Phys.org) —University of Pennsylvania robotics teams are at it again, this time coming up with a robot that aggressively expands the range of how many moves can be made to successfully cross rough terrain full of climbing and leaping challenges. Aaron M. Jonson, and D. E. Koditschek from the University of Pennsylvania’s Kod *lab (a subsidiary of the school’s GRASP Lab) presented their research, “Toward a Vocabulary of Legged Leaping,” at ICRA 2013 in Germany. The video of their device in motion, showing gymnastic-style feats, recently made the rounds of tech sites. The authors also won attention in being one of five finalists for Best Student Paper Award. ICRA stands for the IEEE International Conference on Robotics and Automation. IEEE Spectrum notes that the researchers have progressed toward an X-RHex Light, or XRL, which weighs 6.7 kilograms (14.8 pounds) and has a body length of 51 centimeters (20 inches). The robot has six C-shaped legs, actuated by motors. X-RHex can cross a variety of terrains, including asphalt, grass, sand, mud, and rocks.) RHex began as part of a large DARPA funded consortium. A variety of RHex platforms have been developed ever since.Their “legged-leaping” paper, details their work. “We exhibit on a RHex robot some of the most interesting ‘words’ formed by these achievable path sequences, documenting unprecedented levels of performance and new application possibilities that illustrate the value of understanding and expressing this vocabulary systematically.”Complex hurdles, they wrote, may require special leap capabilities, and that is their focus. They explain further:: “We have presented the space of legged transitions from complete rest to full ﬂight as generated by combinatorial mixtures of various hybrid dynamical systems indexed by the cells of a “ground reaction complex.” They see the value of this exploration as affording new behaviors that “extend the range of terrains that the RHex robot can negotiate.” Explore further Citation: The RHex takes a leap at robotics conference (w/ Video) (2013, May 10) retrieved 18 August 2019 from https://phys.org/news/2013-05-rhex-robotics-conference-video.html XRL robot uses tail for easy landing on springy feet (w/ Video)
A CAD image of the ELI-HAPLS laser. (Phys.org) —Representatives for Lawrence Livermore National Laboratory (LLNL) have announced that researchers and engineers there have been hard at work constructing a “High Repetition-Rate Advanced Petawatt Laser System” (HAPLS)—a laser unlike anything else ever built. The new laser once finished will be transported to Dolní Břežany near Prague, site of the European Union’s Extreme Light Infrastructure (ELI) called ELI Beamlines This document is subject to copyright.

ELI Beamlines is to become for lasers what CERN has been for particle accelerators—a facility for the world’s best scientists to conduct leading edge experiments—it will house some of the most powerful and advanced lasers ever built. Among that collection will be HAPLS, a laser that produces rapidly flickering (10 per second) beams, each just 30 femtoseconds in duration at 30 joules a shot—100 times more powerful than LLNL’s most powerful laser to date—with peak power greater than 1 petawatt. In so doing it will be capable of generating secondary sources of radiation and speeding up charged particles. That will make it ideally suited for an enormous variety of research applications—from biology to physics and medicine—even to materials science. Scientists also envision a whole host of industrial research applications as well.Scientists around the world are expected to be drawn to ELI Beamlines to use the lasers to test theories regarding the cosmos—to emulate what happens with pulsars, for example or to gain more understanding of how matter behaves inside of different stars—all possible because the energy from the short bursts of laser light will be on par with such massive energy producers, if only for a very short period of time. HAPLS is also considered as a possible blueprint for the construction of nuclear fusion facilities some time in the distant future.ELI Beamlines is projected to come online in 2017 and to go into full operation the year after, offering scientists unprecedented access to extraordinarily powerful lasers—what they learn as a result could have far reaching implications well into the future.

Study redefines ecological model: Competition among species can cause geographical isolation Opossums are omnivore marsupials that include 103 known species, sometimes referred to as New World opossums to separate them from cousins living in and around Australia where they are known as possums (they are known by that name in most parts of the southern U.S. as well). Generally a docile animal (known for playing dead when threatened), and sometimes mistaken for really big rats, they have a reputation as a loners, keeping to themselves as they forage. But now, it appears that at least one species engages in gregarious denning, the researchers with this new effort report.Anecdotal evidence of opossums suggests they typically avoid others of their kind (and others of other kinds as well) preferring to keep to themselves. They have been known to hiss when encountering other opossums or other animals.To learn more about the animals, the researchers went out into the field and set up 312 artificial nests in an Atlantic Forest site in Rio de Janeiro, making for rather easy observation of the animals throughout all stages of their lives. They study, conducted over an eight year span included 17,127 observations of opossums in their nests. The team reports that they found ten instances where there were multiple opossums using the same den without being hostile to one another and where there was no sexual activity going on either. They also found one instance where thirteen opossums were living in one nest with members from three different age groups.The team also found that because of the gregarious denning, it appears likely that opossums might engage in social nest building and even pair bonding before mating. They do acknowledge that their results might have been impacted by the nests being artificial in nature—some of the nests were much bigger than those found in nature, and might have contributed to the social behavior of the opossums.

Anecdotal reports suggest that additional interactions occur, including den sharing by a few individuals, usually siblings. Here, we report novel observations that indicate opossums are more social than previously thought. These include nest sharing by males and females of Marmosa paraguayana, Gracilinanus microtarsus and Marmosops incanus prior to the onset of the breeding season and without signs of sexual activity; this is taken to indicate early pair-bonding matching and cooperative nest building. We also recorded den sharing among recently weaned siblings of Didelphis aurita and Caluromys philander. In addition, we observed 13 individuals of Didelphis albiventris representing three age classes resting without agonistic interactions in a communal den. These are the first reports of gregarious behaviour involving so many individuals, which are either unrelated or represent siblings from at least two litters, already weaned, sharing the same den with three adults. Sociality in opossums is probably more complex than previously established, and field experimental designs combining the use of artificial nests with camera traps or telemetry may help to gauge the frequency and extent of these phenomena.

A common, low-stakes living-room scenario: A couple is trying to decide on a movie to watch. There’s an option one-half of the relationship is thrilled about, but the other has already seen it. On those grounds, it’s ruled out. In one experiment, O’Brien and his research team approached people near an exhibit on genetics at Chicago’s Museum of Science and Industry, asking them to rate how much they enjoyed the exhibit and how much they think they’d enjoy perusing it again. While the subjects tended to predict that the exhibit would be less fun the second time around, the ones who did another walkthrough at the researchers’ request rated it roughly as enjoyable as the first. In other words, the museumgoers, as a group, underestimated how much they would like doing the same thing twice. Read the whole story: The Atlantic But a new study suggests that this notion that having already seen it—or read it, done it, visited it—automatically precludes a second go-around might be mistaken. Repeating something, it turns out, “may turn out to be less dull than people think,” writes Ed O’Brien, the author of the study and a behavioral-science professor at the University of Chicago’s Booth School of Business.

Authorities in France seized the passports of six alleged French jihadists who were planning to depart to fight in Syria, the first time this anti-terrorism measure has been used, interior minister Bernard Cazeneuve said on Monday. The ability to seize passports and identity cards of those suspected of imminent departure abroad to wage jihad was one of the key measures of an anti-terrorism bill passed by parliament in November. “Today these six administrative bans on leaving the country have been signed, another 40 are in preparation,” Cazeneuve told reporters outside the interior ministry. “We wanted this measure … because if French people leave to commit actions in Iraq and Syria, upon their return they represent an even greater danger for the national territory and risk committing wide-scale terrorist acts.”
Australia will get a historical perspective of India’s visual art heritage associated with the Ramayana, as the National Museum is lending it 101 miniature paintings on the celebrated epic for an exhibition.The National Gallery of Australia (NGA) in Canberra will next month receive NM’s set of Rama-Katha collection that features varied-style miniature paintings done between the 17th and 19th centuries. Pooled in from India’s northern, central and eastern territories, the grand body of artwork will be on display in the 1967-founded National Gallery of Australia (NGA) for three months from May 22. Also Read – ‘Playing Jojo was emotionally exhausting’Australian Minister for Foreign Affairs Julie Bishop, while announcing this formally here today amid a meeting with India’s Minister of Culture and Tourism Mahesh Sharma, stressed the need for collaborative efforts between nations to promote heritage.“We must be undertaking more such endeavours,” added the minister, who later visited NM and viewed the Rama-Katha series.Sharma noted that the upcoming exhibition strove to re-kindle global interest in Indian miniature paintings, particularly those to the great epics of the country.
