Objective: To assess the impact of a planned research gap year (RGY) on match outcomes and research productivity among urology residency applicants in the context of the highly competitive urology specialty and the new pass/fail format for the USMLE Step 1 exam.

Methods: We conducted an IRB-approved analysis of applicants to our program during the 2022-2023 and 2023-2024 application cycles. Data on demographics, medical school rank, having a home urology program, USMLE Step 1 scores, and ERAS research entries were collected.

The leaf economics spectrum (LES) characterizes a tradeoff between building a leaf for durability versus for energy capture and gas exchange, with allocation to leaf dry mass per projected surface area (LMA) being a key trait underlying this tradeoff. However, regardless of the biomass supporting the leaf, high rates of gas exchange are typically accomplished by small, densely packed stomata on the leaf surface, which is enabled by smaller genome sizes. Here, we investigate how variation in genome size-cell size allometry interacts with variation in biomass allocation (i.

Patients undergoing metabolic and bariatric surgery (MBS) can improve outcomes through a physically active lifestyle. Despite ongoing research, clinical recommendations for physical activity (PA) are not fully developed. For this review, 39 articles representing 24 randomized clinical trials satisfied inclusion criteria.

Endosymbiotic bacteria have a wide range of impacts on host physiology, behavior, metabolism, endurance, and mobility. Recent work found some endosymbionts also impact host sleep duration and quality. These effects may increase as flies age and endosymbiont titers increase.

We detail scientific and engineering advances which enable the controlled spalling and layer transfer of single crystal 4H silicon carbide (4H-SiC) from bulk substrates. 4H-SiC's properties, including high thermal conductivity and a wide bandgap, make it an ideal semiconductor for power electronics. Moreover, 4H-SiC is an excellent host of solid-state atomic defect qubits for quantum computing and quantum networking.
