Published What is the best way to group students? Math model
(via sciencedaily.com) Researchers have developed a new approach that uses math to determine the best ways to group individuals to maximize learning. Their work has broad implications in education, as well as in economics, music, medicine, and sports.
Published The way you talk to your child about math matters
(via sciencedaily.com) 'You're so smart!' -- This encouraging response may actually do more harm than good to children's math performance, according to a new study. The study found that encouraging children with responses related to their personal traits or innate abilities may dampen their math motivation and achievement over time.
Published Pioneering mathematical formula paves way for exciting advances in health, energy, and food industry
(via sciencedaily.com) A groundbreaking mathematical equation has been discovered, which could transform medical procedures, natural gas extraction, and plastic packaging production in the future.
Published Push, pull or swirl: The many movements of cilia
(via sciencedaily.com) Researchers know about many of cilia's roles, but not exactly how they beat in the first place. A new mathematical model aims to uncover the secret to cilia's beating motions.
Published Researchers use computer modeling to understand how self-renewal processes impact skin cell evolution
(via sciencedaily.com) Scientists have used mathematical and computer modeling to demonstrate the impact of skin homeostasis on driver and passenger mutations.
Published Mixing things up: Optimizing fluid mixing with machine learning
(via sciencedaily.com) Fluid mixing is an important part of several industrial processes and chemical reactions. However, the process often relies on trial-and-error-based experiments instead of mathematical optimization. While turbulent mixing is effective, it cannot always be sustained and can damage the materials involved. To address this issue, researchers have now proposed an optimization approach to fluid mixing for laminar flows using machine learning, which can be extended to turbulent mixing as well.
Published Safe havens for cooperation
(via sciencedaily.com) Whether networks with a high level of cooperation emerge in a community depends on how quickly individuals leave -- for example, because they are exploited by others. Researchers investigated this problem by modeling a well-known cooperation game. They consider a spatial network, where players can relocate between different patches if they judge the local conditions to be unfavorable.
Published Ultracold atoms dressed by light simulate gauge theories
(via sciencedaily.com) Researchers have used the coldest systems in the universe to realize in the laboratory gauge theories, key models of modern physics that describe the fundamental forces of Nature and the behavior of complex quantum materials.
Published Researchers discover major roadblock in alleviating network congestion
(via sciencedaily.com) Researchers discovered that congestion control algorithms designed to ensure multiple users sending data over a network do so fairly are actually unable to avoid situations where some users are hogging all the bandwidth.
Published Optical imaging of dynamic interactions between molecules in a cell
(via sciencedaily.com) Researchers develop the 'photoswitching fingerprint analysis'. A unique technology that for the first time allows the analysis of molecular processes and the regulation of individual proteins in living cells with sub-10 nm spatial resolution. The application ranges from biological to medical research.
Published New model predicts how temperature affects life from quantum to classical scales
(via sciencedaily.com) A new theory explains how every process depends on temperature. This theory could help researchers make accurate predictions in a range of areas, including biological responses to climate change, the spread of infectious diseases, and food production.
Published Go with the flow: New findings about moving electricity could improve fusion devices
(via sciencedaily.com) Researchers have found that updating a mathematical model to include a physical property known as resistivity could lead to the improved design of doughnut-shaped fusion facilities known as tokamaks.
Published Advocating a new paradigm for electron simulations
(via sciencedaily.com) Researchers improve a widely used simulation method for high-performance computing clusters.
Published A new model sheds light on how we learn motor skills
(via sciencedaily.com) Researchers have developed a mathematical model of motor learning that reflects the motor learning process in the human brain. Their findings suggest that motor exploration -- that is, increased variability in movements -- is important when learning a new task. These results may lead to improved motor rehabilitation in patients after injury or disease.
Published Sniffing out your identity with breath biometrics
(via sciencedaily.com) Researchers have developed an artificial 'nose' that can identify individuals from their breath. Built with a 16-channel sensor array that can detect different compounds found in a person's breath, the olfactory sensor system has the potential to become another option in the biometric security toolkit. Combined with machine learning, the 'artificial nose' was able to authenticate up to 20 individuals with an average accuracy of more than 97%.
Published Sensor imperfections are perfect for forensic camera analysis
(via sciencedaily.com) In a project aimed at developing intelligent tools to fight child exploitation, computer scientists have developed a system to analyze the noise produced by individual cameras. This information can be used to link a video or an image to a particular camera.
Published Math model predicts efficacy of drug treatments for heart attacks
(via sciencedaily.com) Researchers used mice to develop a mathematical model of a myocardial infarction. The new model predicts several useful new drug combinations that may one day help treat heart attacks, according to researchers.
Published New, highly tunable composite materials--with a twist
(via sciencedaily.com) Mathematicians have found that they can design a range of composite materials from moiré patterns created by rotating and stretching one lattice relative to another. Their electrical and other physical properties can change --s ometimes quite abruptly, depending on whether the resulting moiré patterns are regularly repeating or non-repeating.
Published Radio waves for the detection of hardware tampering
(via sciencedaily.com) Up to now, protecting hardware against manipulation has been a laborious business: expensive, and only possible on a small scale. And yet, two simple antennas might do the trick.
Published Bluetooth signals can be used to identify and track smartphones
(via sciencedaily.com) A team of engineers has demonstrated for the first time that the Bluetooth signals emitted constantly by our mobile phones have a unique fingerprint that can be used to track individuals' movements.
