Acute Effects of Unplanned and Planned Hop-Landing Training on Neurocognitive Function and Knee Biomechanics.

Orthop J Sports Med

January 2025

School of Sport, Rehabilitation, and Exercise Sciences, University of Essex, Wivenhoe Park, Colchester, Essex, United Kingdom.

Background: Athletes with decreased baseline neurocognitive function may experience noncontact anterior cruciate ligament (ACL) injury in unanticipated athletic situations. Many ACL injury prevention programs (IPPs) focus on improving closed-skill movements (eg, planned landing). However, the more open-skill movements (eg, unplanned reactive movements) required in unpredictable sports scenarios are commonly absent from ACL IPPs, and the acute effects of open-skill training on neurocognitive function remain unclear.

Background: Individuals with serious mental illness (SMI) have disproportionately high rates of criminal legal system involvement. For many, this becomes a repeated cycle of arrest and incarceration. Treatments that address symptoms of mental illness are a critical component of the continuum of services for people with SMI in the legal system; yet on their own, psychiatric treatments have not been successful at reducing criminal legal system involvement for this population.

Generative Bayesian Computation for Maximum Expected Utility.

Entropy (Basel)

December 2024

Volgenau School of Engineering, George Mason University, 4400 University Drive, MSN 5D3, Fairfax, VA 22030, USA.

Generative Bayesian Computation (GBC) methods are developed to provide an efficient computational solution for maximum expected utility (MEU). We propose a density-free generative method based on quantiles that naturally calculates expected utility as a marginal of posterior quantiles. Our approach uses a deep quantile neural estimator to directly simulate distributional utilities.

P-selectin glycoprotein ligand-1 (PSGL-1), a mucin-like surface glycoprotein, is primarily expressed on lymphoid and myeloid cells. PSGL-1 has recently been identified as an HIV restriction factor, blocking HIV infectivity mainly through virion incorporation that sterically hinders virion attachment to target cells. PSGL-1 also inhibits HIV Env incorporation into virions.

Revolutionizing Methane Transformation with the Dual Production of Aromatics and Electricity in a Protonic Ceramic Electrocatalytic Membrane Reactor.

ACS Appl Mater Interfaces

January 2025

Department of Hydrogen and Electrochemistry, Idaho National Laboratory, Idaho Falls, ID 83415, United States.

Article Synopsis
  • Using a protonic ceramic electrocatalytic membrane reactor, methane is converted into higher-value chemicals like benzene with high efficiency and minimal emissions.
  • The system achieved a 15.6% methane conversion rate and an 11.4% benzene yield, which outperform traditional thermochemical methods by 15.7% and 16.0%, respectively.
  • The reactor also effectively removes hydrogen, maintaining stable operation for 45 hours and allowing for catalyst regeneration, presenting a promising solution for reducing carbon impact in chemical processing.

Immune events such as infection, vaccination, and a combination of the two result in distinct time-dependent antibody responses in affected individuals. These responses and event prevalence combine non-trivially to govern antibody levels sampled from a population. Time-dependence and disease prevalence pose considerable modeling challenges that need to be addressed to provide a rigorous mathematical underpinning of the underlying biology.

Kinetics and Optimality of Influenza A Virus Locomotion.

Phys Rev Lett

December 2024

Chan Zuckerberg Biohub-San Francisco, 499 Illinois Street, San Francisco, California 94158, USA.

Influenza A viruses (IAVs) must navigate through a dense extracellular mucus to infect airway epithelial cells. The mucous layer, composed of glycosylated biopolymers (mucins), presents sialic acid that binds to ligands on the viral envelope and can be irreversibly cleaved by viral enzymes. It was recently discovered that filamentous IAVs exhibit directed persistent motion along their long axis on sialic acid-coated surfaces.
