From pole parameters to line shapes and branching ratios.

Eur Phys J C Part Fields

June 2024

Helmholtz-Institut für Strahlen- und Kernphysik and Bethe Center for Theoretical Physics, Universität Bonn, 53115 Bonn, Germany.

Resonances are uniquely characterized by their complex pole locations and the corresponding residues. In practice, however, resonances are typically identified experimentally as structures in invariant mass distributions, with branching fractions of resonances determined as ratios of count rates. To make contact between these quantities it is necessary to connect line shapes and resonance parameters.

Background: The field of artificial intelligence (AI)-based patient-specific quality assurance (PSQA) for volumetric modulated arc therapy (VMAT) faces challenges in terms of developing general models across institutions due to the prevalence of multi-institution data collection and multivariate heterogeneity. Building a general model that is capable of handling diverse multi-institution data is critical for enabling large-scale integration and analysis.

Purpose: This study aims to develop a star generative adversarial network (StarGAN) and transformer-based hybrid classification-regression PSQA framework to address unification of heterogeneous data from different institutions.

Article Synopsis
  • Since 2019, SARS-CoV-2 has mutated, leading to various pandemic and epidemic waves that involve changes in its spike protein, which is key for the virus's entry into cells.
  • Researchers studied the spike proteins from variants BA.2.86 and JN.1, discovering structures where ACE2 receptor binds to the spike protein in both up and down conformations.
  • Their findings suggest that the down-conformation of the receptor-binding domain (RBD) is an important intermediate state that helps facilitate the virus's entry, with specific mutations like K356T impacting infectivity and resistance to neutralizing antibodies.

  • A study analyzed the outcomes of chronic total occlusion (CTO) percutaneous coronary interventions (PCI) specifically in patients with anomalous coronary arteries (ACA) from a large dataset of over 14,000 patients between 2012 and 2023.
  • Among 14,470 CTO procedures, only 36 (0.24%) were performed on patients with ACA, who displayed similar baseline characteristics to those without ACA, but had more complicated lesions, requiring longer procedures and greater contrast volume.
  • Despite the increased complexity, ACA patients achieved similar procedural success rates to non-ACA patients, with no major adverse cardiac events reported in the ACA group, indicating a favorable outcome for CTO PCI in

Article Synopsis
  • Single-vehicle crashes, particularly those caused by speeding, lead to more fatalities and serious injuries than other crash types, making it essential to study their causes.
  • The research utilizes data from the National Highway Traffic Safety Administration between 2016 and 2018 and employs machine learning models like XGBoost and Random Forest, along with a mixed logit model, to analyze factors influencing driver injury severity.
  • Key factors identified include driver demographics, reckless driving, restraint usage, roadway characteristics, environmental conditions, vehicle types, crash scenarios, and specific time periods, highlighting the need for better driving behavior and roadway design to reduce speeding and related injuries.

Division of Systems Virology, Department of Microbiology and Immunology, The Institute of Medical Science, The University of Tokyo, Tokyo, Japan.

Due to the incessant emergence of various SARS-CoV-2 variants with enhanced fitness in the human population, controlling the COVID-19 pandemic has been challenging. Understanding how the virus enhances its fitness during a pandemic could offer valuable insights for more effective control of viral epidemics. In this manuscript, we review the evolution of SARS-CoV-2 from early 2022 to the end of 2023-from Omicron BA.

Center for Research and Education in Special Environments, Exercise and Nutrition Department, University at Buffalo, Buffalo, NY 14214, USA.

It is unclear if following a vegetarian diet affects muscle recovery after exercise-induced muscle damage (EIMD). Sixteen vegetarians (VEG) and sixteen mixed dieters (MIX) performed a vertical jump, quadriceps femoris maximal isometric, and isokinetic concentric strength tests prior to and five days following the EIMD protocol. The quadriceps muscle was injured by performing eccentric contractions.

Magnetocaloric effect of topological excitations in Kitaev magnets.

Nat Commun

August 2024

Kavli Institute for Theoretical Sciences, University of Chinese Academy of Sciences, Beijing, 100190, China.

Traditional magnetic sub-Kelvin cooling relies on the nearly free local moments in hydrate paramagnetic salts, whose utility is hampered by the dilute magnetic ions and low thermal conductivity. Here we propose to use instead fractional excitations inherent to quantum spin liquids (QSLs) as an alternative, which are sensitive to external fields and can induce a very distinctive magnetocaloric effect. With state-of-the-art tensor-network approach, we compute low-temperature properties of Kitaev honeycomb model.

The independent effects of hydrostatic pressure and hypercapnic breathing during water immersion on ventilatory sensitivity and cerebrovascular reactivity.

Am J Physiol Regul Integr Comp Physiol

October 2024

Department of Exercise and Nutrition Sciences, Center for Research and Education in Special Environments, University at Buffalo, Buffalo, New York, United States.

Head-out water immersion (HOWI) induces ventilatory and hemodynamic changes, which may be a result of hydrostatic pressure, augmented arterial CO tension, or a combination of both. We hypothesized that the hydrostatic pressure and elevated CO tension that occur during HOWI will contribute to an augmented ventilatory sensitivity to CO and an attenuated cerebrovascular reactivity to CO during water immersion. Twelve subjects [age: 24 ± 3 yr, body mass index (BMI): 25 ± 3 kg/m] completed HOWI, waist water immersion with CO (WWI + CO), and WWI, where a rebreathing test was conducted at baseline, 10, 30, and 60 min, and postimmersion.
