Real-World Versus Centers for Medicare and Medicaid Services Estimates of Pediatric Retinal Detachment Repair Times

Purpose: To compare real-world pediatric retinal detachment (RD) repair times with the Centers for Medicare and Medicaid Services (CMS) estimates for complex RD surgeries. Methods: A cross-sectional survey was performed of complex pediatric RD perioperative times from pediatric r...

Linking social attention to reproductive state and future reproduction in female monkeys

Abstract The demands of complex social life are thought to drive the evolution of cognition in primates. One important approach to testing this hypothesis is to assess if variation in psychological processes impacts an individual’s fitness outcomes, but this can be challenging in...

Generalized Nonlinear Bayesian Pulsar Timing with ENTERPRISE

Abstract We use the Bayesian methods in the ENTERPRISE package to examine the fully general parameterization of pulsar timing models in tandem with noise. We investigate four pulsars, PSRs J1600–3053, J2043+1711, J0740+6620, and J1640+2224, through the lens of Bayesian timing. We...

In vitro evaluation of pH, calcium ion release and interfacial characterization of calcium silicate–based and epoxy resin–based sealers

Abstract This in vitro study evaluated the physicochemical properties and interfacial behavior of four calcium silicate–based sealers (CSBS) compared to an epoxy resin–based sealer. Specimens were prepared under standardized conditions, and pH and calcium (Ca 2+ ) ion release wer...

Improving the Hydrophilicity of the Drugs Paclitaxel, Violacein, and Tetrandrine Using Carbon-Based Quantum Dots

Carbon-based quantum dots and their nitrogen- and sulfur-doped derivatives were used as platforms to improve the aqueous solubility for Paclitaxel, Violacein and Tetrandrine, drugs with known high partition coefficients (Log P). Paclitaxel, Violacein and Tetrandrine showed a sign...

Characterization of prokaryotic communities in Guánica State dry forest caves using 16S ribosomal RNA gene amplicon sequencing

Prokaryotic diversity across four caves and a guano-enriched pond (mud) in Guánica State Dry Forest was characterized using 16S ribosomal RNA gene amplicon sequencing. Microbial profiling varies across the limestone rock formations and dry cave environment, revealing distinct sub...

Research Progress on Thermal Runaway and Thermal Management of Lithium‐Ion Batteries

ABSTRACT Thermal safety remains a critical barrier to the large‐scale deployment of lithium‐ion batteries. This review summarizes recent progress along the full chain from failure onset to system‐level protection. At the single‐cell level, coupled exothermic reactions—SEI decompo...

Interrogating the future of Puerto Rican studies

Puerto Rico has received renewed international attention over the past decade, propelled by a series of compounding disasters. From journalists and academics to activists and global music icons suc...

Crystallizationfor Manufacturing in Microgravity;Are We There Yet?

Abstract Crystallization in microgravity has been extensively investigated because of its potential to enhance crystal quality compared to terrestrial conditions. While early efforts were primarily directed toward single-crystal growth for structural studies, increasing attention...

Integrative Transcriptional and Chromatin Analyses Reveal Enhancer-Mediated Regulatory Programs Driving Breast Cancer Metastasis

Abstract Breast cancer metastasis remains the leading cause of disease-related mortality, yet the regulatory mechanisms enabling tumor cells to adapt to distant tissue environments remain poorly defined. Here, we generated a multi-omic resource integrating transcriptomic (RNA-seq...
