Dyotropic Rearrangement of Hypervalent Iodine Species: Migrative Heterofunctionalization of Quaternary Carbons

ABSTRACT Phenonium intermediates are almost universally invoked to account for 1,2‐aryl migration processes in reactions that exploit in situ‐generated hypervalent iodine(III) leaving groups. Here, we demonstrate that such transformations can instead proceed through a previously...

Ridge Regression Outperforms Optimal Hard Sample-PC Selection in High-Dimensional Isotropic Gaussian Models

We study response-guided selection of sample principal components in isotropic Gaussian linear models with dimension proportional to sample size. Under an exact-cardinality constraint, we derive the risk-minimizing rule among coordinatewise binary selectors based on each sample e...

MitigatingSO2 Poisoning Effect in ElectrochemicalCO2 Reduction with Transition-Metal Single-Atom MolecularCatalysts

Abstract The electrochemical CO2 reduction reaction (CO2RR) offers a promising approach for converting captured CO2 into valuable chemicals and fuels. However, CO2 streams from industrial sources often contain SO2 impurities, which compromise the performance and stability of many...

Visualizing Environments: Toward A Natural History of Science Communication

To illustrate how environmental aesthetics shape present-day science communication pedagogy, this article situates contemporary science communication in the context of the American environmental writing tradition, drawing from the field reporting techniques of William Bartram as...

Course of Portal Hypertension and Its Prognostic Impact After Liver Transplantation

ABSTRACT Background While portal hypertension (PH) typically resolves after liver transplantation (LT), persistence of PH may affect post‐transplant outcomes. We assessed the evolution of PH after LT and its impact on adverse outcomes. Methods We recorded clinical, laboratory, an...

Passive surveillance of infectious bursal disease virus circulating in Egyptian chicken flocks in 2025

Abstract Infectious bursal disease virus (IBDV) causes severe immunosuppression diseases in poultry, resulting in substantial economic losses for the global poultry industry. This study aimed to characterize circulating IBDV strains in Egyptian chicken flocks and assess their pot...

Self-Resetting Synaptic Device toward Low-Power NeuromorphicVision Systems

Abstract Integrating photodetection and optoelectronic synaptic functions into a single device is critical for neuromorphic vision systems. However, such integration typically relies on continuous external biasing and electrical reset pulses for weight regulation, incurring signi...

The Curl Spectrum on Non-Orientable Geometry: Sector Doublets, Vanishing Helicity, and Beltrami Pairs

The spectral theory of the curl operator on closed 3-manifolds is a developed and active field — but exclusively on oriented manifolds, because the definition of curl requires an orientation. This article opens the non-orientable column using the sector calculus. The key is a one...

A causal variational worldline action for modified inertia: the rapidity gap

VERSION 3 CHANGES. The substantive one CORRECTS both earlier versions. (1) The circular-orbit relation was wrong. v1 and v2 both asserted that on a circular orbit |a| is constant and so the acceleration dependence contributes no additional radial force. It does: ahat = a/|a| ROTA...

The effect of context based cooperative problem solving approach on students’ engagement in mathematics learning

This study examined the effect of a context-based cooperative problem-solving instructional approach on students' engagement in mathematics learning. The study involved 166 grade nine students and four teachers from four governmental secondary schools in Addis Ababa. Three treatm...

Learning Along the Way: Novice Teachers’ Reflections on Developing Critical Race Praxis in Urban Schools

This qualitative study investigates how former teacher candidates, trained in critical race inquiry as undergraduates, conceptualize and enact race consciousness and racial literacy in their early years of in-service teaching. Grounded in Critical Race Praxis and Racial Literacy,...

Predicting Structural Progression‐Free Survival After Surgery for Medullary Thyroid Carcinoma

ABSTRACT Introduction Medullary thyroid cancer (MTC) is an aggressive tumor for which surgery is the only curative treatment. However, after surgery, some patients may experience persistence/recurrence. It is important to identify the prognostic factors that may affect structural...

The Incidence of Sensorineural Hearing Loss Diagnoses in People with and without Parkinson's Disease

Abstract Background Parkinson's disease (PD) and sensorineural hearing loss (SNHL) are both prevalent conditions among older adults. Although increasing number of studies have investigated SNHL as a risk factor for PD, it is not well known how diagnosed PD affects the likelihood...

The Frostyverse

The Frostyverse is a narrative-driven conceptual toy universe and proposed computational research program. It explores whether one discrete elastic grid could provide an intuitive common architecture for matter, radiation, gravity, electromagnetism, confinement, structural decay,...

Projected Manifestation of Topological Break: A Unified Yuanxian Reading of the Tunguska Event, Climate Imbalance, Geological Catastrophes and Plagues

Yuanxian Theory defines the cosmos as a closed self-referential living organism (T64). Continuity of the T64 closed chain depends on local nodes continuously producing TCSC fixed-point confirmation signals. When a local node long fails to form an effective self-referential closed...

Symmetry-EnabledCoexistence of Linear and NonlinearHall Responses in Mn2NSF Janus MXene

Abstract The controlled realization of simultaneous linear and nonlinear Hall responses within a single material platform remains a central challenge in quantum geometric transport. Here, using first-principles density functional theory in conjunction with maximally localized Wan...

Robust Nonvolatile Memory and Synaptic Emulation via Dual‐Mode Modulation in ReS 2 /h‐BN/Ta 2 NiSe 5 Floating‐Gate Device

ABSTRACT The integration of optical sensing with neuromorphic computing offers a promising pathway to overcome the von Neumann bottleneck in data‐intensive artificial intelligence applications. However, realizing robust nonvolatile storage with synergistic electrical and optical...

Biobased Fibrous Films Enabling Synergistic Thermal Conduction and Radiative Cooling for Personal Thermal Management

Abstract Personal thermal management materials are increasingly in demand under intensifying outdoor heat exposure and global warming. However, simultaneously achieving efficient radiative cooling, rapid thermal conduction, mechanical flexibility, and sustainability within a simp...

Genetic Predisposition and Pharmacological Effects Shape the Divergent Effects of Type 2 Diabetes on Atherosclerosis

Abstract Type 2 diabetes mellitus (T2D) increases the risk of atherosclerotic diseases, including coronary artery disease (CAD), but decreases that for abdominal aortic aneurysm (AAA), forming an intriguing diabetes-atherosclerosis paradox. We investigate how genetic underpinning...

Adjusting to becoming parents by adoption: a systematic review of qualitative research through thematic synthesis

Research highlights the varying experiences individuals have when seeking to become parents for the first time or wishing to extend their existing family through adoption. This review synthesizes qualitative literature on these experiences. Nine papers were analyzed using themati...
