Microsoft Announces Windows Mobile 6.5 (PhysOrg.com) — Sidekick users have been without some of their services for days, and have just been told by the company, T-Mobile, that for some users their data may be lost forever due to a server error at Microsoft subsidiary, Danger. Citation: Sidekick’s lost data gone for good (2009, October 12) retrieved 18 August 2019 from https://phys.org/news/2009-10-sidekick-lost-good.html T-Mobile has published an apology to affected users for what is turning out to be one of the most spectacular failures in cloud computing. The massive data loss also suggests entrusting personal data to the cloud may not be as safe as users have been led to believe. The loss of services and data was caused by a disruption to services, but details are sketchy.The problems began last week with a massive outage at Danger. Many Sidekick users lost access to their key data, because almost all the data is stored in the cloud, with no copy on the device itself. On Saturday, Microsoft admitted that any data it had not yet recovered is almost certainly permanently lost.T-Mobile has offered to compensate affected users with a free month of services, but neither T-Mobile, nor Microsoft have revealed how many users have been affected. Users who have lost their data would need to rebuild it themselves, but many have not backed up their data since they believed it was safe. Data affected includes contact lists, calendar details, personal information and photographs.T-Mobile is warning users not to power off their Sidekick device, to reset it, or to remove the battery or allow the battery to go flat. If they do, they will lose any remaining personal data they currently have in their device, since the data that was backed up on the Danger servers has been lost.Another update from T-Mobile and Microsoft on the current state of the repairs is expected to be issued today.© 2009 PhysOrg.com Explore further This document is subject to copyright.

Honda Motors has always imagined the future in its automobile designs and technology. But this year, Honda’s imagination has come up with a design, a technology, and an extremely cool-looking, practical vehicle that millions of folks would buy right now, if given the opportunity. Combining Honda’s engineering with European design (Italian, no less) and you’ve got a winner in the 3R-C.Unfortunately, Honda’s 3R-C is a concept car… a three-wheeled concept car, a trike… and most auto bloggers in the know agree that it will never be built. If that is so, it’s really a pity. Citation: The Honda 3R-C: Designed For The NOW (2010, March 1) retrieved 18 August 2019 from https://phys.org/news/2010-03-honda-3r-c.html Honda Introduces All-New Insight Dedicated Hybrid Concept Vehicle at Paris Motor Show Honda 3R-C Concept (Image: Honda) The 3R-C is an all electric trike with its lithium battery stored low under the chassis for vehicle stability. The thick door-like sides are high, offering a nice separation between the driver and the front end of another vehicle, as well as a shield from wind and water. And if frontal protection from the elements is needed, the 3R-C’s canopy, which covers the vehicle when not in use, becomes a windshield.And, unlike your friendly neighbor’s motorcycle, the 3R-C doesn’t make noise. When you want to buzz to the store and back, no one really has to know your comings and goings. Oh yes, you also get more than a basket for your groceries. The Honda trike has a lockable trunk in front of the driver’s seat, which is more than handy when you need to make multiple shopping stops. And, of course, you can lock up the driver’s seating compartment with the canopy.In U.S. cities with plenty of public transportation available and high-occupancy vehicle (HOV) lanes that offer speed inducement from the suburbs to the city, as of the last published census report, still 77 percent of commuters drive to work alone. In the states, HOV lanes have been around since the 1980’s and usership is still embarrassingly low. This document is subject to copyright.

Journal information: Physical Review Letters © 2012 Phys.org More information: Unconventional Josephson Effect in Hybrid Superconductor-Topological Insulator Devices, Phys. Rev. Lett. 109, 056803 (2012) DOI:10.1103/PhysRevLett.109.056803AbstractWe report on transport properties of Josephson junctions in hybrid superconducting-topological insulator devices, which show two striking departures from the common Josephson junction behavior: a characteristic energy that scales inversely with the width of the junction, and a low characteristic magnetic field for suppressing supercurrent. To explain these effects, we propose a phenomenological model which expands on the existing theory for topological insulator Josephson junctions.Physics Viewpoint: An Extraordinary Josephson Junction Citation: Researchers find unusual behavior in Josephson junction superconductor-topological insulator devices (2012, August 1) retrieved 18 August 2019 from https://phys.org/news/2012-08-unusual-behavior-josephson-junction-superconductor-topological.html Explore further (Phys.org) — Researchers at Stanford have been investigating the special properties of a Josephson junction when constructed as hybrid superconducting-topological insulator devices and have found what appears to be some unconventional behavior. In their paper published in Physical Review Letters, they describe how in applying a superconductor-topological insulator to a Josephson junction, the diffraction that occurs appears to differ from theoretical theories.

Long predicted but never observed: A new kind of quantum junction A Josephson junction is where a device is made that allows, theoretically, for an infinite electrical current to flow. This should be possible because superconductors, by their very name, conduct electricity so well that no energy is lost when electrons pass through them. To construct a Josephson junction, researchers couple two superconductors together with a weak link between them. What is interesting about the construction of such a device though, is when the two superconductors have different phase shifting properties which cause a phase shift in the electrons as they pass through. What’s more if a magnetic field is applied, than that can cause a phase shift as well.In this new research, the team applied a superconducting form of aluminum on top of a bit of bismuth selenide, which is a topological insulator. To create a Josephson junction, they left a little gap between the two and then applied a magnetic field and a small amount of current.In measuring the results, they were surprised to find that the diffraction that occurred due to the phase shift didn’t correspond to the conventional Fraunhofer pattern as expected. Instead they found that the valleys were higher, which they suggest could have been due to the size area of the junction being smaller. But they also found that the shape of the curve itself was different. Together the unconventional results suggest that something else is at work in the junction and the team suggests that it might just be due to the emergence of particles that show a remarkable similarity to Majorana fermions – charge neutral particles (fermions) that are their own antiparticles.This new work goes a long way towards proving that Majorana fermions really can be created using superconductors, thus proving the theories true, and if that is the case, then actual devices should be able to be built that create and manipulate them at will, opening the door to all manner of applications that until now have existed only in science fiction stories.
(Phys.org) —Last month, researchers reported the creation of the first primitive brain-like structures made from human stem cells. To create the complex morphology of these cerebral organoids, cells within a proliferating neuroectodermal layer were converted into so-called radial glial precursors (RGPs), which then rough out the basic floor plan of the cerebrum. As seen in the image above, the migrating and replicating RPGs span the thickness of the telencephalon in a normally developing brain, and provide a scaffolding for later arriving cells to subsequently migrate on themselves. A new paper published in Cell describes how the division of RPGs is tightly controlled by the location of the nucleus as it is motored about between the poles of the extended cell. The authors expand upon earlier work detailing the precise cytoskeletal couplers which power these translocations in specific directions, and ultimately piece together how these motor proteins, specifically dynein, are harnessed by nuclear pore complexes. Once this motor-nuclear mating occurs, migration in the apical direction (in this context, apical is towards the ventricle and basal is towards the surface) is initiated followed by subsequent entry into mitosis.

Explore further © 2013 Phys.org Journal information: Cell While the nucleus undergoes dramatic restructuring throughout the cell cycle, the individual pore complexes themselves are among the longest-lived protein structures in the cell. Together with a few other kinds of proteins, like the collagens, or specific histones, they can maintain their structure over the lifetime of the organism itself. In their latest research, the researchers were able to identify a number of proteins that inhibited the recruitment of dynein to the pore complex using a technique known as RNA interference (RNAi). The particular form of the technique they employed here made use of more stable RNA known as shRNA, for short hairpin. By injecting these inhibitors directly in utero, at embryonic day 16 rats, they then looked at the effects on RGP cells in living slices of tissue from embryonic day 20.The researchers found that the interfering RNAs arrested the cells in the G2 phase of the cycle. By rebuilding and adding supplementary dynein proteins, and targeting them to the nuclear pore, this effect could be rescued. The specially modified dynein dramatically increased the number of RGP cells found at the ventricular surface. The authors suggest that the amount of dynein recruited to the nuclear envelope region was therefore sufficient to overcome the opposing forces generated kinesin-3 which are responsible for basal nuclear migration during the G1 phase.The authors observed that the centrosomes remained at the ventricular surface during the periods of nuclear foraging to the basal pial layer (pia is the membranous covering of the brain). Their findings that the motor complex is instead associated with the nucleus in the RGP cells represents an uncommon mechanism. Why this mechanism of tightly coupled migration and mitotic entry evolved is currently unknown but the authors speculate that ectopic cell divisions must somehow interfere with proper neurogenesis.Nuclear migration to the ventricular surface provides direct access to the centrosomes which are assembling the mitotic spindle, and also to additional cues that appear to specify cell fate. The exact orientation of this spindle apparatus has emerged as an important regulator of cell fate, and the subsequent migration of neural and glial progeny. Further exploration of this system may give additional clues about the mechanisms that ultimately specify the size and particular geometry of the cortex.

The antenna has a 68 cm parabolic dish reflector and a low noise block (LNB). According to the paper, LNB receives the radio signal from the satellite reflected by the dish and amplifies it. There is also a set-top box that powers the satellite finder and the LNB. Satellite finder is used for orienting satellite dishes towards geostationary satellites. “We have used a commercially available analog satellite finder (GC SF-02). Such a device acts as a square law detector and is used to read directly the intensity,” the team wrote in the paper. Citation: Students develop an affordable everyday radio telescope (2016, February 2) retrieved 18 August 2019 from https://phys.org/news/2016-02-students-everyday-radio-telescope.html Arduino Uno is a microcontroller board with a 10 bit analog to digital converter. It enables digitizing the intensity from the satellite finder at 10Hz sampling rate. The tool is connected to a personal computer.The students emphasize that their radio telescope, assembled from commonplace items, is an affordable and a versatile instrument to demonstrate the working of a radio telescope and to provide crucial hands-on experience with radio astronomy tools. It goes without saying that one of the main advantages of their instrument is its low cost.”In India, this telescope cost was less than $75. However, it is highly dependent on rates of components available at your place,” Agarwal said.The project also leaves a lot of space for future improvements. For instance, an increase in sensitivity would offer the opportunity to look at many other sources than just the sun. “All-sky visibility maps can be generated at a rudimentary level that would make one familiar with a bigger part of the radio sky,” the team concluded. (Phys.org)—A team of undergraduates from the Indian Institute of Science Education and Research (IISER) at the College of Engineering in Trivandrum, India, has designed and constructed a portable college-level radio telescope for amateur radio astronomers. The students have developed a radio telescope and also data analysis tools that are affordable for schools and colleges, combining low cost and ubiquitous accessibility of resources needed to build these instruments. The team described the project in details in a paper published online on Jan. 12 on the arXiv pre-print server. “The telescope is dedicated to amateur radio astronomers ranging from high school students to college graduates,” Devansh Agarwal, one of the co-authors of the paper, told Phys.org.While large radio telescopes are needed to detect radio waves from astronomical sources, the students have shown that a small one could also make great discoveries in the field of radio astronomy. A small radio telescope designed by the team was able to measure the brightness temperature of the sun. The scientists also demonstrated the usefulness of their telescope by detecting point sources such as Saturn and extended sources such as the galactic arm of our home galaxy Milky Way.The team revealed that by performing drift scans, the brightness temperature of the sun was calculated to near 10,000 K with a maximum error of 3.23 percent. Sources like Saturn and the galactic arm were confirmed by correlating the time of arrival of the source signal in the field of view of the telescope with the predicted times via free, open-source planetarium software called Stellarium, based on the team’s pointing. The flux received from the sources was calibrated against the standardized data from various geostationary satellites.Agarwal notes that their radio telescope reached expectations when studying the sun and also works very well when detecting other astronomical sources.The radio telescope designed by IISER students consists of a satellite antenna, a satellite signal meter called ‘satellite finder’ and a microcontroller board named Arduino Uno.

DOI: 10.1056/NEJMicm1501197AbstractA human sneeze can eject droplets of fluid and potentially infectious organisms. The image sequence captures, in increments of 20 msec, the emission of a sneeze cloud produced by a healthy person. The sneeze was produced naturally, without the introduction of additives, colorants, or contaminants for visualization. High-speed video (Video 1, normal speed; Video 2, slowed down by a factor of 67), recorded at 1000 frames per second, shows a turbulent cloud that consists of hot and moist exhaled air, mucosalivary filaments and drops, and residues from droplet evaporation (nuclei). The ejection lasts up to 150 msec (top row) and then transitions into a freely evolving turbulent puff cloud (middle and bottom rows). The largest droplets rapidly settle within 1 to 2 m away from the person. The smaller and evaporating droplets are trapped in the turbulent puff cloud, remain suspended, and, over the course of seconds to a few minutes, can travel the dimensions of a room and land up to 6 to 8 m away.

DOI: 10.1056/NEJMicm1501197 Explore further Humans sneeze because the body becomes aware of a foreign substance in the sinuses and reacts by forcefully expelling them. Unfortunately, bacteria and viruses can be expelled along with other material in cloud matter which can then be inhaled by other people in the area—causing them to become infected with a disease. In order to better understand what happens during a sneeze, Bourouiba and her team enlisted the assistance of several volunteers—each agreed to being photographed during the act of sneezing.Viewing the results at normal and high speed revealed that there was more going on than expected. First, the researchers found that there were many kinds of movements, such as swirls and eddies. Second, they found that there was a wide range of droplet sizes—some relatively large and some very small. They also found that the cloud formed by a sneeze was very much impacted by the environment in which it occurred—air movement, humidity levels and temperature all had an impact on not only the size of the cloud, but its shape and duration. Most surprisingly of all, perhaps, was the finding that the tiniest droplets could remain suspended in the air for up to several minutes under the right conditions, and could travel as far as several feet. This meant, the researchers explain, that one person sneezing in a room could potentially infect every other person in that room.The goal of the experiments, the researchers note, is to better understand what happens with sneeze clouds in places like hospitals so that changes can be made to reduce their size and duration. While research continues, they suggest that everyone sneeze into their elbows rather than directly into the air around them or into their hands. The objective should be to slow the droplets by causing them to collide with some object, such as a sleeve. (Phys.org)—A team of researchers at MIT led by Lydia Bourouiba has discovered some new properties of sneeze clouds by photographing them with high speed cameras and then studying the footage. In their paper published in the New England Journal of Medicine, the researchers note that the physics of a sneeze cloud are more complicated than might be expected from such a simple event.

The blowout turned the sand in the area to quicksand, and a drilling rig sank and disappeared into the ground. After a period of time, the area was converted into a park. But now, the area is back in the news, because the researchers with this new effort have discovered that the site is still leaking methane. NAM has also been in the news of late due to recent evidence implicating the company as the cause of small earthquakes impacting Groningen, a province just north of the former gas field.The researchers made the discovery while looking into the environmental impact of shale gas production, including its possible contamination of groundwater. To learn more, they began testing well water in and around the park and the farmland that surrounds it. They report finding abnormally high levels of methane in the water and that its isotopic composition (its chemical signature) was very similar to that of the gas reservoir, suggesting that methane is leaking from cracks made below the surface as part of natural gas drilling operations a half-century ago.The methane gas emissions do not present a health hazard, the researchers note, because methane is regularly cleared from drinking water as part of normal processing. But it could pose a problem if the gas accumulates in a building or structure—that could result in an explosion. But that, too, is unlikely, they further report, because the amount of gas being emitted drops quickly as distance from the site increases. More information: Gilian Schout et al. Impact of an historic underground gas well blowout on the current methane chemistry in a shallow groundwater system, Proceedings of the National Academy of Sciences (2017). DOI: 10.1073/pnas.1711472115AbstractBlowouts present a small but genuine risk when drilling into the deep subsurface and can have an immediate and significant impact on the surrounding environment. Nevertheless, studies that document their long-term impact are scarce. In 1965, a catastrophic underground blowout occurred during the drilling of a gas well in The Netherlands, which led to the uncontrolled release of large amounts of natural gas from the reservoir to the surface. In this study, the remaining impact on methane chemistry in the overlying aquifers was investigated. Methane concentrations higher than 10 mg/L (n = 12) were all found to have δ13C-CH4 values larger than −30‰, typical of a thermogenic origin. Both δ13C-CH4 and δD-CH4 correspond to the isotopic composition of the gas reservoir. Based on analysis of local groundwater flow conditions, this methane is not a remnant but most likely the result of ongoing leakage from the reservoir as a result of the blowout. Progressive enrichment of both δ13C-CH4 and δD-CH4 is observed with increasing distance and decreasing methane concentrations. The calculated isotopic fractionation factors of εC = 3 and εD = 54 suggest anaerobic methane oxidation is partly responsible for the observed decrease in concentrations. Elevated dissolved iron and manganese concentrations at the fringe of the methane plume show that oxidation is primarily mediated by the reduction of iron and manganese oxides. Combined, the data reveal the long-term impact that underground gas well blowouts may have on groundwater chemistry, as well as the important role of anaerobic oxidation in controlling the fate of dissolved methane. A team with members from several institutions in the Netherlands has found that the area around a site where a gas explosion occurred in 1965 is still emitting methane gas from the ground into the air. In their paper published in Proceedings of the National Academy of Sciences, the group describes their study of the area and the degree of hazard the gas leak poses.

Kolkata: A Cafe Coffee Day (CCD) outlet in Salt Lake was robbed by four miscreants in broad daylight on Monday.Just after the cafe was opened in the morning, four miscreants entered and tied the on-duty service boy Suvankar Ghosh. It was alleged that one of the miscreants took Ghosh on gunpoint so that he did not raise an alarm. According to police sources, Ghosh said around 10:20 am he opened the cafe and was preparing to start the day and welcome customers. Within a few minutes, four persons entered the cafe and surrounded him. One of them took out a gun and pointed it towards his forehead threatening to kill if he raised an alarm.

While two were busy with the service boy, the other two were standing guard. After tying Ghosh, the miscreants opened the cash box and took out the money — approximately Rs 18,000 and fled. A few minutes later, Ghosh managed to untie himself and immediately called the area manager Sumit Singh and narrated the whole incident. Singh called the zonal business head Md Sarfaraz and took Ghosh in a conference call. During the call, Sarfaraz told Singh to reach the cafe at the earliest. He also directed Ghosh to dial 100 and call the police. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed”Ghosh was crying.

Kolkata: The Mamata Banerjee government will witness an expansion on Thursday with four new faces being inducted into it.The new ministers will be sworn in during a function at Raj Bhavan at 1.30 pm. Governor K N Tripathi will conduct the oath of secrecy. Four MLAs who are likely to become ministers are Tapas Roy, Sujit Bose, Ratna Ghosh and Dr Nirmal Maji. Once these MLAs are inducted, the number will go up to 44. Four ministers have been dropped since the second term of the TMC in office after winning the 2016 Assembly elections. They are Sovan Chatterjee, Abani Joardar, James Kujur and Chudamani Mahato. Also Read – Rain batters Kolkata, cripples normal lifeThe decision to expand the ministry is to reduce the burden on some ministers and better the functioning of the state government. For example, Firhad Hakim looks after the Urban Development and Municipal Affairs department along with Fire and Emergency Services. He is also the Mayor. Moloy Ghatak looks after Law, Labour and Public Health Engineering departments. Aroop Biswas also looks after three departments, namely Sports, Youth Affairs and Public Works (PWD) Department. Sukumar Hansda is likely to be appointed as the Deputy Speaker in the West Bengal Legislative Assembly which fell vacant following the death of Haider Aziz Safwi. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedTo improve the administrative work of the respective departments, Chief Minister Mamata Banerjee has been holding regular administrative review meetings in the districts since she came to power in 2011. These meetings give an opportunity to the officials working in the districts to interact with the Chief Minister and other senior bureaucrats directly including the Chief Secretary which helps to resolve local issues. Also, the MLAs get a chance to talk to the Chief Minister over the ongoing projects and place their demands if any. If they are justified, Banerjee is often found taking up immediate measures and on many occasions, has asked the concerned Principal Secretary or the Additional Chief Secretary to resolve the matter. Of the four MLAs likely to be inducted, Tapas Roy, MLA from Baranagar is the deputy chief whip. He is associated with the government functioning for many years. Sujit Bose, MLA from Salt Lake, is well known for his organisational capabilities while Nirmal Maji is the president of the State Medical Council and chairman of Rogi Kalyan Samity of Calcutta Medical College and Hospital. In the next three years, there will be three elections. The Lok Sabha election will be held in 2019 followed by the Kolkata Municipal Corporation (KMC) polls in 2020 and then the Assembly election in 2021. Hence, the Chief Minister is leaving no stone unturned and wants to complete all the pending work on time.
