New theory and understanding of how liquid nano-jets breakup into dropletsComputer simulations of molecules show how droplets from a "nano-tap" would differ from those produced by a household tap 1 million times largerResearchers at the University of Warwick have re-written the classical 19th century text-book theory of breakup to capture dominant nanoscale physicsApplications are to emerging 21st century nano-technologies: next generation ink-jet printing, drug delivery, and lab-on-chip devices that diagnose infections and diseases in situDroplets emanating from a molecular "nano-tap" would behave very differently from those from a household tap 1 million times larger - researchers at the University of Warwick have found.This is potentially crucial step for a number of emerging nano technologies, e.g., manufacture of nano-sized drug particles, lab-on-chip devices for in situ diagnostics, and 3D printers capable of nanoscale resolution.
Smartish system has a good stab at prioritizing patients, has problems deciding what's critical, thoArtificially intelligent software can help slash the wait times for patients anxious to see the results of their X-ray scans, it is claimed.Long waiting times are the bane of hospitals worldwide.And, so, researchers from the King’s College London and the University of Warwick in old Blighty believe they can alleviate the X-ray results backlog by using a mixture of computer vision and natural language processing techniques.Essentially, trained software looks at someone's X-ray scan and suggests whether they should be seen immediately and given their results, or made to wait in a queue with others, based on how serious their condition is.“The increasing clinical demands on radiology departments worldwide has challenged current service delivery models, particularly in publicly-funded healthcare systems,” said Giovanni Montana, coauthor of the research published in Radiology and a professor at Warwick, earlier this week.
OAK BROOK, Ill. - An artificial intelligence (AI) system can interpret and prioritize abnormal chest X-rays with critical findings, potentially reducing the backlog of exams and bringing urgently needed care to patients more quickly, according to a study appearing in the journal Radiology.The number of exams can create significant backlogs at health care facilities."Currently there are no systematic and automated ways to triage chest X-rays and bring those with critical and urgent findings to the top of the reporting pile," said study co-author Giovanni Montana, Ph.D., formerly of King's College London in London and currently at the University of Warwick in Coventry, England.Deep learning (DL), a type of AI capable of being trained to recognize subtle patterns in medical images, has been proposed as an automated means to reduce this backlog and identify exams that merit immediate attention, particularly in publicly-funded health care systems.The radiologic reports were pre-processed using Natural Language Processing (NLP), an important algorithm of the AI system that extracts labels from written text.For each X-ray, the researchers' in-house system required a list of labels indicating which specific abnormalities were visible on the image.
New research has found that a novel Artificial Intelligence (AI) system can dramatically reduce the time needed to ensure that abnormal chest X-rays with critical findings will receive an expert radiologist opinion sooner, cutting the average delay from 11 days to less than 3 days.Chest X-rays are routinely performed to diagnose and monitor a wide range of conditions affecting the lungs, heart, bones, and soft tissues.Researchers from WMG at the University of Warwick, working with Guy's and St Thomas' NHS Hospitals, extracted a dataset of half million anonymised adult chest radiographs (X-rays) and developed an AI system for computer vision that can recognise radiological abnormalities in the X-rays in real-time and suggest how quickly these exams should be reported by a radiologist.In the process of building the AI system, the team developed and validated a Natural Language Processing (NLP) algorithm that can read a radiological report, understand the findings mentioned by the reporting radiologist, and automatically infer the priority level of the exam.The research team, led by Professor Giovanni Montana, Chair in Data Science in WMG at the University of Warwick, found that normal chest radiographs were detected with a positive predicted value of 73% and a negative predicted value of 99%, and at a speed that meant that abnormal radiographs with critical findings could be prioritised to receive an expert radiologist opinion much sooner than the usual practice.The results of the research are published today, 22nd January 2019 in the leading journal Radiology in a paper entitled "Automated triaging and prioritization of adult chest radiographs using deep artificial neural networks."
Radiologists are drowning in x-rays.The electromagnetic scans account for a whopping 40 percent of all diagnostic imaging worldwide, and in the U.K. alone, there are an estimated 330,000 x-rays at any given time that have waited more than a month for a report.Fortunately, artificial intelligence (AI) promises to shrink the backlog substantially.In a new study published in the journal Radiology, scientists at the University of Warwick describe a system that can automatically prioritize x-rays, picking out scans in urgent need of attention.“Currently there are no systematic and automated ways to triage chest x-rays and bring those with critical and urgent findings to the top of the reporting pile,” Giovanni Montana, who coauthored the study, said in a statement.The researchers sourced a database of 470,388 adult chest x-rays that had been stripped of identifying information and annotated.
A genetic mutation that causes abnormalities in adolescent's brains can predict Schizophrenia later in life according to researchers from the University of WarwickThe amount of gray matter on the brain is associated to the gene mutationNew methods to prevent schizophrenia can now be developedSchizophrenia could be caused by a genetic mutation that causes a structural abnormality in the brain during adolescence.Therefore testing for the gene SLC39A8, and brain scans for schizophrenia could predict whether or not someone will develop it - researchers at the University of Warwick have found.Abnormal brain development in adolescence is associated with adult mental illness.
Astronomers using the ALMA telescope have discovered an oddly tilted planet-forming disk within a double binary star system, a configuration that up until this point only existed in theory.Quadruple star systems featuring two binary pairs are nothing unusual, nor is the discovery of a surrounding protoplanetary disk – a ring of gas and dust that gradually congeals to form planets.A star system located 146 light-years from Earth, called HD 98800, has all these things, but as new research published today in Nature Astronomy reveals, this system features an exceptionally strange protoplanetary disk.The pair on the inside, called BaBb, are in close proximity to each other, around 1 AU, which is the average distance from the Earth to the Sun.But never mind the outer pair – it’s the inner pair and its surrounding disk that’s interesting.Normally, a protoplanetary disk rests along the same plane as the orbital plane of its binary star hosts.
Eventually, the sun will cool off and become a giant crystal floating through space.It's not a bizarre science fiction plot, but the takeaway of new scientific research published this week in the journal Nature.You may have heard that billions of years down the road the sun will swell to a ravenous red giant star that will eventually swallow Earth.But long after our planet has been ended, the sun will shrink to a cool white dwarf star and then slowly solidify into a massive white crystal, the study says.That's a lot of bling wasted on the empty vacuum of space."All white dwarfs will crystallize at some point in their evolution, although more massive white dwarfs go through the process sooner," Pier-Emmanuel Tremblay from the University of Warwick's Department of Physics in the UK explained in a statement.
Around 3 billion people worldwide currently drink or smoke - new research could help in both the prevention and treatment of alcohol and nicotine substance abuse.In new research the areas of the brain that are different in those who smoke and those who drink have been identified: the tendency to drink alcohol is associated with increased connectivity of brain networks associated with reward processing; and the tendency to smoke is associated with low connectivity of systems that respond to not receiving rewards.These differential tendencies to alcohol and nicotine consumption can even be detected in young people before much drinking or smoking has started, thanks to new research led by the University of Warwick.Academics at the University of Warwick have found that low functional connectivity of the lateral orbitofrontal cortex that is associated with the tendency to smoke is associated with increased impulsiveness - which may contribute to the tendency to smoke.A new study by Professor Jianfeng Feng, Professor Edmund Rolls from the Department of Computer Science at the University of Warwick, in collaboration with Dr. Wei Cheng from Fudan University, China, examined the neural mechanisms underlying two key types of substance use behavior, smoking and drinking.In 2000 participants they found that smokers had low functional connectivity in general, and especially in the lateral orbitofrontal cortex, a region of the brain associated with impulsive behavior.
- Just one night of disturbed sleep means you are less capable to control posture and balance the day after- A single bad night sleep decreases your chance of controlling posture according to researchers at the University of Warwick, who have used state of the art sensors to monitor sleep and balance- Implications could be that older people who have had a bad night sleep are the most at risk of a fall- Innovative solutions of how to prevent imminent falls can now be researchedDisturbances during sleep decreases capability to control posture and balance according to researchers from the Department of Engineering and Warwick Medical School at the University of Warwick who have an article published today in Scientific Reports.This is the first study demonstrating the relationship between disrupted sleep and the reduced capability to control posture and balance, and it could pave the way to new interventions to prevent falls in later life, should the results be confirmed by other studies on older adults.
In particular, it increased the probability that a non-aligned voter would decide to vote for candidate Trump by at least five percentage points, according to the results of the study.On the other hand, "the results show that Clinton did not manage to increase support among her potential natural voters nor boost their participation in the elections.Unfortunately, we do not have the necessary data to be able to understand why it worked for Trump and not for Clinton", two of the authors of the paper point out, Ángel and Rubén Cuevas, researchers from the UC3M Telematics Engineering department.This disparity shows there are other variables to consider in addition to the presence of social media.Specifically, political micro-targeting was particularly effective when based on ideology, gender or educational level, much less so when based on race or age."Our results show that learning about politics on Facebook does not make voters more informed, but does make them less likely to change their voting choice, which is very in line with the concept of political polarisation.
New Rochelle, NY, October 22, 2018--Board games can engage patients in play and fantasy, and by enabling face-to-face interaction, can help educate patients on health-related knowledge and behaviors.A new systemic review and meta-analysis of trials assessing the outcomes achieved using board games in children through older adults is published in Games for Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers.Click here to read the full-text article free on the Games for Health Journal website through November 22, 2018.Andrea Gauthier, University of Toronto (Mississauga, Canada), Pamela Kato, Kim Bul, Ian Dunwell, and Petros Lameras, Coventry University (Coventry, U.K.), and Aimee Walker-Clarke, University of Warwick (Coventry, U.K.) coauthored the article entitled "Board Games for Health: A Systematic Literature Review and Meta-Analysis."The article evaluated 21 studies of non-digital board games, the majority of which used education to increase health-related knowledge and behaviors.The goal of the systemic review and meta-analysis was to answer two main questions: what kinds of board games targeting medical and health-related outcomes have been evaluated in the literature; and what has been the overall impact of the board games on health-related outcomes?
Developing and testing new steel alloys will be up to 100 times faster, allowing new products to reach the market more quickly, thanks to £7 million of funding announced today for a new "virtual factory" being developed by Swansea University, in partnership with Tata Steel and WMG, at the University of Warwick.It is indispensable for national infrastructure such as transport, communications and energy, and for high-tech 21st century industries, from energy-positive buildings to wind turbines and electric vehicles.Swansea University, Tata Steel and WMG, at the University of Warwick, which have a long history of collaboration on steel research, have won funding from the Engineering and Physical Sciences Research Council (EPSRC), through the Prosperity Partnership initiative, to tackle this problemTheir solution is to combine physical testing and computational modelling to rapidly assess hundreds of small-scale samples, covering areas such as strength, electrical and mechanical properties, as well as durability and resistance to corrosion.The difference this new approach will make is enormous:100 samples can be tested in the time it currently takes to test one

His reasoning was simple: the networks undermine democracies in ways that cannot be fixed with software updates, he said.In each, they analyzed the local community by any variable that seemed relevant.This asymmetry of passion makes it appear as if refugees have less support than they actually do, which in turn inspires more people to gang up against them.Here are Taub and Fisher again:German internet infrastructure tends to be localized, making outages isolated but common.Or it can tweak its distribution mechanisms to minimize overall user engagement with Facebook, which would also reduce the amount of ad money it collects.

Synthetic reproductions of antifreeze proteins found in polar fish can be used to cryopreserve - or 'freeze' - bacteriaRevolutionary approach is more effective than current industry standardThe findings could radically improve storage and transportation of human organs, food and medicine - and advance laboratory researchThe survival mechanisms of polar fish have led scientists at the University of Warwick to develop of a revolutionary approach to 'freeze' bacteria.Researchers from the Department of Chemistry and Warwick Medical School have established a way to cryopreserve (or 'freeze') a broad range of bacteria using synthetic reproductions of the natural antifreeze proteins found in polar organisms.They found that adding the protein mimics slows ice crystal growth and stops them destroying the bacteria cells.
Einstein's theory of general relativity has passed its toughest-ever test with flying colors, a new study reports.General relativity, which the great physicist proposed in 1916, holds that gravity is a consequence of space-time's inherent flexibility: Massive objects distort the cosmic fabric, creating a sort of well around which other bodies orbit.[Einstein's Theory of Relativity Explained (Infographic)]Researchers have confirmed the equivalence principle many times on Earth — and, famously, on the moon.In 1971, Apollo 15 astronaut David Scott dropped a feather and a hammer simultaneously; the two hit the gray lunar dirt at the same time.(On Earth, of course, the feather would flutter to the ground much later than the hammer, having been held up by our atmosphere.)
A recently released research paper shows the age-old adage about saying something nice is true, even in the modern era, and especially with an unconventional president.University of Warwick researchers Karsten Müller and Carlo Schwarz found evidence that suggests Donald Trump’s tweets about Islam have led to an increase in anti-Muslim hate crimes over the past few years.Using the FBI’s hate crime database, the pair first took a wide view of any recorded hate crime between 1990 and 2016, before limiting the scope of the search to hate crimes against Muslims after Trump took office.The number of these crimes not only increased under Trump, it’s the highest number in recorded history, including the months following 9/11 under the Bush administration.The data also showed a strong statistical correlation between the number of Trump’s tweets about Islam, and an uptick in crimes in the days and weeks that followed.“To be clear, we do not claim that Donald Trump himself causes hate crimes out of thin air,” Carlo Schwarz, a doctoral student who worked on the study, told The Daily Beast.
First ever detailed pictures of conjugated polymers - which conduct electricity and are highly sought after - captured with novel visualisation technique developed by University of WarwickNew approach realises Richard Feynman's famous remark that it would be very easy to make an analysis of any complicated chemical substance; all one would have to do would be to look at it and see where the atoms are"Polymers need alternating pattern of "A" monomer & smaller "B" monomer (ABAB), but the researchers discovered surprising gaps & defects in polymer structure - an ABBA patternThe first ever detailed pictures of the structure of conjugated polymers have been produced by a research team led by Professor Giovanni Costantini at the University of Warwick.The ability of these polymers to conduct electricity makes them highly sought after, but until now they could also be described as extremely camera shy as there has been no easy means to determine their structure.The new technique allows researchers not only to determine it but to actually clearly see it with their own eyes.
