  • Ultrafast and coupled: Atomic vibrations in the quantum material boron nitride

    Materials consisting of a few atomic layers display properties determined by quantum physics. In a stack of such layers, vibrations of the atoms can be triggered by infrared light. New experimental and theoretical work shows that atomic vibrations within the layers of hexagonal boron nitride, the so-called transverse optical phonons, couple directly to motions of…

  • Autonomous driving: Saving millions in test kilometers

    Researchers have developed a method to validate test drives through highly realistic driving simulation studies and to substantially simplify the approval process for automated driving systems. New regulation as initial spark Recently, because the first global regulation for Automated Lane Keeping Systems (ALKS) has been in force since the beginning of 2021. This law resolves…

  • Mathematical model developed to prevent botulism

    Food producers can use a mathematical model to ensure their products do not cause botulism. For refrigerated products, the guidelines for controlling Clostridium botulinum indicate that the water contained in the products should have a salt content of at least 3.5%. Unfortunately, this hampers efforts to develop salt-reduced products, even though such products would benefit…

  • Mathematical model predicts effect of bacterial mutations on antibiotic success

    Scientists have developed a mathematical model that predicts how the number and effects of bacterial mutations leading to drug resistance will influence the success of antibiotic treatments. Their model, described today in the journal eLife, provides new insights on the emergence of drug resistance in clinical settings and hints at how to design novel treatment…

  • Machine learning can help slow down future pandemics

    Artificial intelligence could be one of the keys for limiting the spread of infection in future pandemics. In a new study, researchers have investigated how machine learning can be used to find effective testing methods during epidemic outbreaks, thereby helping to better control the outbreaks. In the study, the researchers developed a method to improve…

  • Mathematical modeling to identify factors that determine adaptive therapy success

    Researchers report results from their study using mathematical modeling to show that cell turnover impacts drug resistance and is an important factor that governs the success of adaptive therapy. Cancer treatment options have increased substantially over the past few decades; however, many patients eventually develop drug resistance. Physicians strive to overcome resistance by either trying…

  • Computational medicine: Moving from uncertainty to precision

    An innovative partnership takes aim at medicine down to the individual level by applying state-of-the-art computation to medical care. An innovative partnership at The University of Texas at Austin takes aim at medicine down to the individual level by applying state-of-the-art computation to medical care. «Medicine in its essence is decision-making under uncertainty, decisions about…

  • Mathematical constructions of COVID virus activity could provide new insight for vaccines, treatment

    Mathematical constructions of the action of SARS-CoV-2 and its multiple spikes, which enable its success at infecting cells, can give vaccine developers and pharmaceutical companies alike a more precise picture of what the virus is doing inside us and help fine tune prevention and treatment. Mathematical construction enables examination of the activity of individual virus…

  • Mathematicians build an algorithm to ‘do the twist’

    Mathematicians have developed an algorithm to decipher the rotational dynamics of twisting particles in large complex systems from the X-ray scattering patterns observed in X-ray photon correlation spectroscopy experiments. These experiments — designed to study the properties of suspensions and solutions of colloids, macromolecules, and polymers — have been established as key scientific drivers to…

  • Mathematical models and computer simulations are the new frontiers in COVID-19 drug trials

    Researchers are using computer models to simulate COVID-19 infections on a cellular level which allows for virtual trials of drugs and vaccines, opening the possibility of pre-assessment for drug and vaccine efficacy against the virus. The models allow for virtual trials of drugs and vaccines, opening the possibility of pre-assessment for drug and vaccine efficacy…
