Published Using math to better treat cancer
(via sciencedaily.com) Researchers have identified a new method for scheduling radiation therapy that could be as much as 22 percent more effective at killing cancer cells than current standard radiation treatment regimens.
Published Moral behavior pays off
(via sciencedaily.com) Coupling two approaches of game theory can shed light on how moral norms evolve.
Published Mathematicians explain how some fireflies flash in sync
(via sciencedaily.com) A new study by mathematicians shows that math borrowed from neuroscience can describe how swarms of these unique insects coordinate their light show, capturing key details about how they behave in the wild.
Published Unveiling the dimensionality of complex networks through hyperbolic geometry
(via sciencedaily.com) Original source Reducing redundant information to find simplifying patterns in data sets and complex networks is a scientific challenge in many knowledge fields. Moreover, detecting the dimensionality of the data is still a hard-to-solve problem. A new article presents a method to infer the dimensionality of complex networks through the application of hyperbolic geometrics, which capture the complexity of relational structures of the real world in many diverse domains.
Published Mathematical modeling suggests U.S. counties are still unprepared for COVID spikes
(via sciencedaily.com) Original source America was unprepared for the magnitude of the pandemic, which overwhelmed many counties and filled some hospitals to capacity. A new study suggests there may have been a mathematical method, of sorts, to the madness of those early COVID days.
Published Music class in sync with higher math scores -- but only at higher-income schools
(via sciencedaily.com) Music and arts classes are often first on the chopping block when schools face tight budgets and pressure to achieve high scores on standardized tests. But it's precisely those classes that can increase student interest in school and even benefit their math achievement, according to a new study.
Published Number-crunching mathematical models may give policy makers major headache
(via sciencedaily.com) Policy makers assume that adding more detail to mathematical models will produce more accurate predictions, but that's not always the case, a new study shows.
Published Predicting risk of aneurysm rupture
(via sciencedaily.com) Predicting the rupture of aneurysms is crucial for medical prevention and treatment. As aspect ratio and size ratio increase and an aneurysm expands, the stress applied against the aneurysm walls and the time blood spends within it increase. This leads the probability of rupture to rise. Researchers develop a patient-specific mathematical model to examine what aneurysm parameters influence rupture risk prior to surgery. Computed tomography scans are fed into the model, which reconstructs the geometry and blood flow of the aneurysm. It then uses equations to describe the fluid flow, generating information about the blood vessel walls and blood flow patterns.
Published Study shows how math, science identity in students affects college, career outcomes
(via sciencedaily.com) Two researchers have published a study that asked students if they see themselves as a math or science person, then followed up with them several times in following years. Results showed those who said yes in ninth grade were much likelier to major in STEM subjects and work in related fields after college. The results show the importance of helping students have positive math and science experiences early and could be a way to help address equity gaps in STEM.
Published As few as 1 in 5 COVID cases may have been counted worldwide, mathematical models suggest
(via sciencedaily.com) Mathematical models indicate that as few as one in five cases of COVID-19 which occurred during the first 29 months of the pandemic are accounted for in the half billion cases officially reported.
Published Mathematics enable scientists to understand organization within a cell's nucleus
(via sciencedaily.com) Researchers have developed a new mathematical technique to begin to understand how a cell's nucleus is organized. They hope this understanding will expose vulnerabilities that can be targeted to reprogram a cell to stop cancer or other diseases.
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.
