(Phys.org) -- University of Japan researchers have worked on a camera system that tracks fast-moving objects in realtime, automatically keeping fast moving objects centered. The system can track fast-moving objects with high accuracy, called “amazing.” A video demo has been made that reveals their success. This is a pan-tilt system that keeps an object at the center of the field. The researchers started work based on a challenge they recognized in the broadcast of major sports events such as the World Cup and games at the Olympics, where videos that are powerful and of the highest quality are in demand. http://phys.org/news261589950.html Technology Sun, 15 Jul 2012 16:52:46 EST news261589950 With the Atlantic hurricane season officially beginning this month, the Office of Naval Research (ONR) is pursuing a number of projects to help Navy forecasters and meteorologists around the world predict storms better. http://phys.org/news258288868.html Space & Earth Thu, 07 Jun 2012 11:54:38 EST news258288868 As voters increasingly rely on websites of presidential primary candidates for news, they run a risk because candidates' online attacks are not vetted through traditional "watchdog journalists" and other gatekeepers to determine accuracy or fairness, according to a study by Baylor University researchers. http://phys.org/news258050471.html Other Sciences Mon, 04 Jun 2012 17:41:19 EST news258050471 Marking another remarkable collaborative effort, ESA and NASA met up over the Arctic Ocean this week to perform some carefully coordinated flights directly under CryoSat orbiting above. The data gathered help ensure the accuracy of ESA’s ice mission. http://phys.org/news252832193.html Space & Earth Thu, 05 Apr 2012 08:10:05 EST news252832193 Field measurements in the spectacular blue ice region of Antarctica not only provide confidence in the accuracy of ESA’s CryoSat mission, but have also shown that this part of the ice sheet has increased in height. http://phys.org/news252316403.html Space & Earth Fri, 30 Mar 2012 08:53:35 EST news252316403 (PhysOrg.com) -- Researchers from the NIST Center for Nanoscale Science and Technology and the NIST Material Measurement Laboratory have demonstrated that a simpler technique for calibrating lateral sensitivity in an atomic force microscope (AFM) agrees with an earlier method developed at NIST to within 5 %. http://phys.org/news252231031.html Nanotechnology Thu, 29 Mar 2012 09:10:57 EST news252231031 Nagoya University researchers and Fujitsu Ltd. have developed technology they say can analyze suspicious phone conversations and detect bank transfer scams with a high degree of accuracy. http://phys.org/news252149112.html Technology Wed, 28 Mar 2012 11:00:02 EST news252149112 Inspired by the work of psychologists who study the human face for clues that someone is telling a high-stakes lie, UB computer scientists are exploring whether machines can also read the visual cues that give away deceit. http://phys.org/news251981558.html Technology Mon, 26 Mar 2012 11:52:48 EST news251981558 The faster a clock ticks, the more precise it can be. Due to the fact that lightwaves vibrate faster than microwaves, optical clocks can be more precise than the caesium atomic clocks which presently determine time. The Physikalisch-Technische Bundesanstalt (PTB) is even working on several of such optical clocks simultaneously. The model with one single ytterbium ion caught in an ion trap is now experiencing another increase in accuracy. At PTB, scientists have succeeded in exciting a quantum-mechanically strongly "forbidden" transition of this ion and – in particular – in measuring it with extreme accuracy. The optical clock based on it is exact to 17 digits after the decimal point. The results are published in the current edition of the scientific journal Physical Review Letters. http://phys.org/news250517615.html Physics Fri, 09 Mar 2012 12:13:49 EST news250517615 (PhysOrg.com) -- A study team at the University of Buffalo, State University of New York, is working on video analysis software to analyze eye movements to spot liars. So far, they say their results show that their software can spot liars with a promising level of accuracy. Their claim is based on their study using 40 people. Their system correctly identified who was telling the truth and who was lying 82.5 percent of the time. http://phys.org/news250403710.html Technology Thu, 08 Mar 2012 05:40:01 EST news250403710 (PhysOrg.com) -- Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider purchasing. For scientists, reducing uncertainty is a no less important goal, though in the weird realm of quantum physics, the term has a more specific meaning. http://phys.org/news249480424.html Physics Sun, 26 Feb 2012 13:00:01 EST news249480424 Thrombin plays a key role in various pathologies of the haemostatic system. Overexpression of thrombin can result in thrombosis, whereas its underexpression might lead to haemophilia. Therefore, accurate monitoring of thrombin activity is crucial for determining the proper treatment of a given patient, as this correlates with the ability of blood to coagulate. A tool for monitoring the activity of thrombin over time is the so-called thrombin generation test (TGT). http://phys.org/news249220505.html Chemistry Thu, 23 Feb 2012 11:55:43 EST news249220505 On a recent blustery afternoon, scientists gathered on a rooftop at the Georgia Tech Research Institute (GTRI) to observe two atmospheric electric field-mill devices monitor the buildup of electrical charge in nearby clouds. The larger device was a commercial model costing about $5,000. The smaller one, built by five Georgia high-school students using a coffee can, electrical components and a motorcycle battery, cost about $200. http://phys.org/news247912894.html Technology Wed, 08 Feb 2012 08:42:07 EST news247912894 Spacecraft must operate with utmost precision when conducting landing maneuvers on other planets, or docking to a space station. To ensure they do not drift off course, imaging sensors collect a fl ood of data that are analyzed in real time. Researchers at the Fraunhofer Institute for Computer Architecture and Software Technology FIRST have engineered a system based on multicore technologies that allow spacecraft to be piloted and positioned with pinpoint accuracy. It can be seen at the embedded world trade show in Nuremberg from February 28 to March 1, 2012. http://phys.org/news247306078.html Technology Wed, 01 Feb 2012 08:20:01 EST news247306078 Heisenberg's Uncertainty principle is arguably one of the most famous foundations of quantum physics. It says that not all properties of a quantum particle can be measured with unlimited accuracy. Until now, this has often been justified by the notion that every measurement necessarily has to disturb the quantum particle, which distorts the results of any further measurements. This, however, turns out to be an oversimplification. In neutron experiments carried out by professor Yuji Hasegawa and his team at Vienna University of Technology, different sources of quantum uncertainty can now be distinguished, validating theoretical results by collaborators from Japan. The influence of the measurement on the quantum system is not always the reason for uncertainty. Heisenberg's arguments for the uncertainty principle have to be revisited – the uncertainty principle itself however remains valid. The results have now been published in the journal Nature Physics. http://phys.org/news246019189.html Physics Tue, 17 Jan 2012 10:40:39 EST news246019189 Most people remember listening to the official UK top 40 singles chart and watching the countdown on Top of the Pops, but can science work out which songs are more likely to 'make it' in the chart? New research has looked at whether a song can be predicted to be a 'hit'. http://phys.org/news243318121.html Technology Sat, 17 Dec 2011 04:22:30 EST news243318121 Peer review of scientific research is an essential component of research publication, the awarding of grants, and academic promotion. Reviewers are often anonymous. However, a new study by researchers at the Johns Hopkins Bloomberg School of Public Health found that greater cooperation between reviewer and author can improve accuracy of the review. Their study is published in the Nov. 9 edition of the journal PLoS ONE. http://phys.org/news240066806.html Other Sciences Wed, 09 Nov 2011 17:00:08 EST news240066806 (PhysOrg.com) -- For almost sixty years, the world has considered the atomic clock the gold standard for keeping time. Its accuracy is such that it drifts by only about four seconds over a period of about thirteen and a half billion years (about the time since the Big Bag is thought to have occurred). Now it appears a new more accurate way to measure time might be on the horizon. Corey Campbell at the Georgia Institute of Technology and five of his colleagues have teamed together to describe in their paper pre-published on arXiv, how a more accurate nuclear clock might be devised. http://phys.org/news240051821.html Physics Wed, 09 Nov 2011 09:40:01 EST news240051821 A team of computer scientists, physicists, and physicians at Harvard have developed a simple yet powerful method of visualizing human arteries that may result in more accurate diagnoses of atherosclerosis and heart disease. http://phys.org/news238948539.html Technology Thu, 27 Oct 2011 15:35:54 EST news238948539 New information on the role of insoluble dust particles in forming cloud droplets could improve the accuracy of regional climate models, especially in areas of the world that have significant amounts of mineral aerosols in the atmosphere. A more accurate accounting for the role of these particles could also have implications for global climate models. http://phys.org/news237726723.html Space & Earth Thu, 13 Oct 2011 12:12:20 EST news237726723 The study on single-nucleotide resolution structural variations (SVs) of an Asian and African genome was published online in Nature Biotechnology. This study was performed by BGI (previously known as the Beijing Genomics Institute), the largest genomics organization in the world, and demonstrates that whole genome de novo assembly could serve as a new solution for developing a more comprehensive SV map of individuals. http://phys.org/news230805656.html Biology Mon, 25 Jul 2011 10:30:01 EST news230805656 Scientists have shown that soccer players with superior ability in areas such as passing accuracy or sprint speed do not necessarily achieve better overall performance on the pitch. http://phys.org/news228713307.html Other Sciences Fri, 01 Jul 2011 04:41:19 EST news228713307 A student writing an essay for their teacher may be tempted to plagiarize or leave facts unchecked. A new study shows that if you ask that same student to write something that will be posted on Wikipedia, he or she suddenly becomes determined to make the work as accurate as possible, and may actually do better research. http://phys.org/news226054452.html Other Sciences Tue, 31 May 2011 09:54:29 EST news226054452 (PhysOrg.com) -- DLR, an aerospace agency based in German, has modified its flagship robot, known as the Rollin’ Justin, in order to make it into a lean, mean, catching machine. The Rollin’ Justin's modifications allow the machine to catch balls that are thrown in its direction with an accuracy rate of about 80%. The Rollin’ Justin's robots accuracy rating is better than the average uncoordinated human. It is certainly better than this reporters accuracy rate. It is not as good as say, a Major League Baseball player, but then again most of us cannot say that we are as good as the pros either. Considering they also have near unlimited stamina, at least until the battery runs out, it may be a great partner for the standard game of catch, or for the position behind the batter. http://phys.org/news223303954.html Electronics Fri, 29 Apr 2011 13:52:47 EST news223303954 A team of researchers from Concordia University has developed an effective new technique to determine the authorship of anonymous emails. Tests showed their method has a high level of accuracy – and unlike many other methods of ascertaining authorship, it can provide presentable evidence in courts of law. Findings on the new technique are published in the journal Digital Investigation. http://phys.org/news218809615.html Technology Tue, 08 Mar 2011 12:31:01 EST news218809615 Consumers may place a high value on information to predict their future health, and may be willing to pay out of pocket to get it. In a national survey conducted by researchers at Tufts Medical Center, roughly 76% of people indicated that they would take a hypothetical predictive test to find out if they will later develop Alzheimer's disease, breast or prostate cancer, or arthritis. On average, respondents were willing to pay $300 to $600, depending on the specific disease and the accuracy of the test. http://phys.org/news213617761.html Medicine & Health Fri, 07 Jan 2011 10:16:20 EST news213617761 An Italian research team confirmed that the scoring system for Wilson's disease (WD) provides good diagnostic accuracy with 93% positive and 92% negative predictive values, respectively in children with mild liver disease. In asymptomatic children, a urinary copper excretion above 40 μg/24 hours was suggestive of WD, however the penicillamine challenge test (PCT) did not provide an accurate diagnosis in this patient subset. Results of the study appear in the December issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases (AASLD). http://phys.org/news210345094.html Medicine & Health Tue, 30 Nov 2010 14:10:02 EST news210345094 Researchers at Mount Sinai School of Medicine have found that the naturally-occurring hormone oxytocin selectively improves social cognitive abilities for less socially proficient individuals, but has little effect on those who are more socially proficient.
