Analysis of birefringence modulation performance in RM-embedded CO-polymer waveguides

Uncontrolled birefringence causes measurement errors and signal distortion in high-precision optical systems, yet existing modulation methods suffer from complex fabrication or poor stability. Polymer waveguides serve as low-cost, flexible alternatives to traditional lithium niob...

Error Estimates of an Exponential Wave Integrator for the Nonlinear Schrödinger Equation with Singular Potential

Abstract. In this paper we analyze a first-order exponential wave integrator (EWI) for the nonlinear Schrödinger equation (NLSE) with a singular potential that is locally in [Formula: see text], which might be locally unbounded. A typical example is the inverse power potential su...

A Normal Map-Based Proximal Stochastic Gradient Method: Convergence and Identification Properties

Abstract. The proximal stochastic gradient method ([Formula: see text]) is one of the state-of-the-art approaches for stochastic composite-type problems. In contrast to its deterministic counterpart, [Formula: see text] has been found to have difficulties with the correct identif...

MultifunctionalSingle-Transistor Architecture Enabledby Nonvolatile Band Rearrangement in 2D Ferroelectric Tunneling Junction

Abstract A defining challenge for next-generation nanoelectronics is integrating diverse functionalities within a single device while strictly minimizing power consumption. Two-dimensional (2D) ferroelectrics, with their atomic-scale nonvolatility, offer a promising platform for...

Gestational Diabetes Mellitus: Recurrence and Future Type 2 Diabetes Risk Across Racial and Ethnic Groups

OBJECTIVE Despite rising diabetes prevalence among women, data on long-term diabetes risk following gestational diabetes mellitus (GDM), particularly its recurrence, remain limited, especially for Asian women. This study examined associations among GDM, its recurrence, and subseq...

Charge-ResonancePolymerization at Donor–AcceptorInterfaces Enables Large-Area Organic Magnetic Membranes

Abstract Electron acceptors such as tetracyanoquinodimethane (TCNQ) and its fluorinated analogue F4TCNQ are foundational to charge-transfer and doping chemistry. At interfaces formed by deposition of these acceptors onto donor substrates, reduced anionic species can naturally coe...

Multimodal Bioinspired Self‐Healing Composites Enabling Durable and High‐Efficiency Wearable Perovskite Light‐Emitting Diodes

ABSTRACT Wearable and flexible optoelectronic devices are rapidly advancing toward human‐interactive applications. However, their operational lifespan is often limited by mechanical damage, interface delamination, and environmental influences. Existing encapsulation methods provi...

Cannabinoids suppress chemotherapy- and ionizing radiation-induced apoptosis of glioblastoma cells

Abstract Cancer patients are increasingly exposed to cannabinoids, the bioactive molecules produced by the Cannabis sativa La. plant. This trend is being driven by several factors: expanding cannabis legalization, FDA approval of select cannabinoids for the treatment of seizures...

Experimental causal inference from measurements alone in the presence of spatial and temporal quantum correlations

The causal structure of a set of events specifies which events influence which others. Determining this structure, known as causal inference, is a fundamental task in science. Reset-style intervention is commonly used to determine causal structure in classical scenarios. However,...

Associations of carboxypeptidase A1 and gamma-glutamyltransferase 1 genotypes with refractory functional dyspepsia: a potential link to pancreatic pathophysiology and refractory dyspepsia

Background and Aims This study aimed to investigate the associations between SNPs in CPA1, GGT1, and SPINK1 genes and the clinical characteristics of refractory FD including clinical symptoms, pancreatic enzyme abnormalities, and exocrine pancreatic function.Methods 97 Patients w...

Correlated insulator Moiré bolometer

Light incident on an insulator is generally not expected to turn it into a metal without invoking intense ultrafast excitation that leads to transient structural transitions. Here we show that magic-angle twisted bilayer graphene tuned to half filling of the moiré band provides a...

Atomic High-Spin Cobalt Unlocks Reversible Multi-Electron Transfer Chemistry for Superb Aqueous Zn-Mn Batteries

Abstract To settle inherent irreversible phase transition and motivate re-dissolution of deposited “dead” MnO 2 without acid and redox mediator addition, we introduced atomic-dispersed Co atoms with high-spin state into layered MnO 2 , denoted as Co–MnO 2 , via an in situ topolog...

A tutorial on fitting flexible meta-analytic models with structural equation modeling in R

Abstract There are various statistical models with different features and assumptions in meta-analysis. Popular models include the fixed-effect (or common effect), random-effects, and mixed-effects models. Apart from these models, several alternative models, such as the multiplic...

Spin-quenching cobalt center for efficient ammonia synthesis derived from oxide mixology

The spin polarization plays a critical role in heterogeneous catalysis by influencing the properties of active sites and thereby altering catalytic performance. However, precise construction of active sites with well-tuned spin states remains challenging. Here we demonstrate to m...

Artificial intelligence-enabled insights into dietary modifications driving the progression from metabolic dysfunction-associated steatotic liver disease to hepatocellular carcinoma

Dietary patterns represent a major modifiable risk factor contributing to metabolic dysfunction-associated steatotic liver disease (MASLD), which can lead to insulin resistance, inflammation, gut dysfunction and hepatic steatosis. Diet-induced animal models have become essential...

Phenotypes of painful TMDs and bruxism based on clinical, psychosocial and somatosensory features: a cluster analysis

To identify pain phenotypes among individuals with bruxism and painful temporomandibular disorders (TMD) by integrating clinical, psychosocial, and somatosensory variables. This cross-sectional observational study included 54 adults who self-reported and were clinically assessed...

Age-Associated Patterns of Cardiovascular Risk and Disease Phenotypes Across Diverse Care Settings: The GLOB-cAGE Consortium

Reported prevalence of cardiovascular disease (CVD) risk factors and phenotypes varies widely. In multi-cohort analyses, such variation reflects population risk, care setting, and data capture. We harmonized baseline data from four analytic cohorts (N=54,188, aged ≥50 years) in f...

High‐Performance Self‐Assembled Amphiphilic Block Copolymer Thermoelectric Ionogel for Low‐Humidity Heat Harvesting

ABSTRACT Ionic thermoelectric (i‐TE) materials have attracted considerable interest due to their abilities to generate high thermovoltage for low‐grade waste heat harvesting. However, challenge still remains to develop high‐performance i‐TE materials, especially at relative low h...

Characterisation of liver disease using quantitative MRI: report of the imaging arm of the ELEGANCE study

Evolving disease aetiology and rising prevalence of chronic liver disease are driving an increase in hepatocellular carcinoma (HCC). Non-contrast quantitative MRI (qMRI) has shown promising capability for characterising liver health and risk of liver related outcomes, but has not...
