Medicare Risk Arrangement and Use and Outcomes Among Physician Groups.
JAMA Netw Open
January 2025
America's Physician Groups, Washington, DC.
Importance: Many physician groups are in 2-sided risk payment arrangements with Medicare Advantage plans (at-risk MA). Analysis of quality and health resource use under such arrangements may inform ongoing Medicare policy concerning payment and service delivery.
Objective: To compare quality and efficiency measures under 2 payment models: at-risk MA and fee-for-service (FFS) MA.
Assessment of Long-Term Cultivated In Vitro Willow Clones according to Chromosomal Analysis.

Voronezh State University, Voronezh, Russia.
Creation and long-term in vitro maintenance of valuable genotype collection is one of the modern approach to conservation of valuable gene pool of woody plants. However, during prolonged cultivation, genetic variability of cells and tissues may accumulate and lead to the loss of valuable characteristics of parental plants. It is therefore important to assess the genetic (including cytogenetic) stability of collection clones.

Layered sulfide crystals are suitable hosts for lithium and sodium ions in batteries. In this study, new layered lithium titanium sulfide (LTS) crystals were grown in a sealed silica tube using a LiS self-flux at 800-950 °C. X-ray diffraction (XRD) analysis results indicated the formation of a new sulfide phase with higher symmetry in the Li-Ti-S system.

Small
January 2025
Key Laboratory of Aerospace Materials and Performance (Ministry of Education) School of Materials Science and Engineering, Beihang University, No.37 Xueyuan Road, Beijing, 100191, P. R. China.
A reasonable construction of hollow structures to obtain high-performance absorbers is widely studied, but it is still a challenge to select suitable materials to improve the low-frequency attenuation performance. Here, the FeO@C@NiO nanoprisms with unique tip shapes, asymmetric multi-path hollow cavity, and core-shell heteroepitaxy structure are designed and synthesized based on anisotropy and intrinsic physical characteristics. Impressively, by changing the load of NiO, the composites achieve strong absorption, broadband, low-frequency absorption: the reflection loss of -55.

January 2025
Jayhawk Athletic Performance Laboratory-Wu Tsai Human Performance Alliance, Department of Health, Sport and Exercise Sciences, University of Kansas, Lawrence, KS 66045, USA.
Objectives: The purpose of this study was twofold: (a) to profile body composition and physical fitness characteristics of collegiate American football starters and (b) to examine differences in key performance indicators across position groups. These indicators included select measures of body composition, joint kinematics, as well as muscular strength and power.
Methods: Sixteen National Collegiate Athletic Association (NCAA) Division-II American football athletes (age: 22.
