Developing COLLAT: Initial validation of a multidimensional collocation awareness assessment using signal detection and Rasch modeling

Research on multiword expressions—including collocations, idioms, and lexical bundles—has advanced substantially; however, most assessments focus on accuracy- and knowledge-oriented measures rather than the awareness processes underlying that knowledge. This article reports the d...

Discovery of Novel Pyridazine-Containing Nicotinamide Derivatives as Potent FTO Inhibitors for Acute Myeloid Leukemia

Abstract FTO has been recognized as a promising therapeutic target for acute myeloid leukemia (AML). However, the development of FTO inhibitors with anti-leukemia effects was still limited. Here, based on reasonable design and SAR, a total of 67 compounds were synthesized, among...

Negative Interfacial Tension Driven by Intrinsic Molecular Disorder

Abstract Intrinsically disordered molecular systems, such as random copolymers and intrinsically disordered proteins, exhibit scale-invariant, power-law cluster distributions that cannot be explained by conventional mean-field theories. A fundamental challenge is to understand ho...

Clinical effectiveness of Er, Cr: YSGG laser compared with conventional rotary instrumentation for caries removal in primary teeth: a randomized split-mouth clinical trial

To compare the clinical efficacy of erbium, chromium-doped yttrium scandium gallium garnet (Er, Cr: YSGG) laser versus conventional air-rotor handpiece for caries removal in primary teeth and their effects on children’s anxiety and pain levels, to provide evidence for optimizing...

MG2CL: Multi-Granularity Graph Contrastive Learning for Skeleton-Based Action Recognition

Skeleton-based action recognition has gained increasing attention as a robust alternative to RGB-based methods due to its resilience to background clutter and lighting variations. Existing approaches have achieved notable progress, particularly with graph-based models that captur...

Steering Reaction Coordinates on Laser-Programmed Fe/FeO/Ag Electrodes for Nitrate-to-Ammonia Electrosynthesis

Abstract Electrocatalytic nitrate reduction to ammonia (NO3RR) offers a dual-benefit strategy for pollution remediation and sustainable NH3 synthesis, but steering the complex eight-electron/proton reaction coordinate on earth-abundant iron catalysts remains challenging due to sl...

High-Quality InSb Nanowires Grown by Molecular-Beam Epitaxy via Precise Catalyst Modulation

Abstract Semiconductor InSb nanowires are a major material candidate for topological quantum computation. The nanowires in current devices were mostly grown using metal–organic chemical vapor deposition, which is incompatible with in situ growth of superconductors, a crucial requ...

Optimal direct instantaneous torque control of a switched reluctance motor for low torque ripple

Purpose This paper aims to present an optimal direct instantaneous torque control (DITC) based on enhanced linear active disturbance rejection control (LADRC) using a fast modeling approach. Design/methodology/approach First, a fast modeling approach based on the torque balance m...

Ultra‐High Contrast Terahertz Modulation and Pixelated Display Based on VO 2 Metasurface

ABSTRACT The development of high‐performance, dynamically reconfigurable devices is important for advancing Terahertz (THz) technology. Vanadium dioxide (VO 2 ), a metal‐insulator transition oxide with a near‐room‐temperature critical point, is promising for infrared (IR) and THz...

Multi-Temperature VOCs + OH Rate Coefficients Prediction via GCN Constrained by the Arrhenius Equation

Abstract Based on the accumulation of the high-quality databases from experimental measurements and theoretical calculations, data-driven machine learning approaches has been widely applied to rate coefficient prediction. However, most existing models are confined to single-tempe...

Non‐Contact Photoplethysmography for In‐Vehicle Health Monitoring With Seamlessly Integrated Photodetector Array and Hardware‐Accelerated AI

ABSTRACT While non‐contact physiological monitoring offers clear advantages over contact‐based methods in dynamic environments such as intelligent vehicles, its practical deployment remains constrained by low signal‐to‐noise ratio (SNR) and susceptibility to motion artifacts. Her...

Cultural bias or universal traits? Exploring personality-like profiles of large language models

Abstract Do large language models (LLMs) exhibit coherent personality profiles, and are these profiles culturally neutral? This study used two validated personality inventories, the Big Five Inventory–2 and the Dark Triad Dirty Dozen, to assess five state-of-the-art LLMs (ChatGPT...

Spray‐Driven Corrosion‐Resistant Superhydrophobic Coating With Multiscale Particles Reinforcement and Its Applicability to Various Environments

ABSTRACT Insufficient mechanical strength and tedious preparation processes of corrosion‐resistant superhydrophobic coatings have long restricted their practical application. In this work, a superhydrophobic coating is proposed through the incorporation of multiscale micro‐glass...

Efficient Waveform Capture without Absorption with Synthesis of Complex Frequencies

Abstract An optical waveform can be synthesized using complex-frequency waves as well as real-frequency harmonic waves. While a single complex-frequency wave with exponentially rising waveform can be perfectly absorbed in lossless structures. Here, we propose that diverse optical...

Tuning the Frontier Molecular Orbitals of Aromatic Radicals via Chalcogen Substitution and Heterocyclic Stabilization

Abstract Due to the intrinsic electron-donating effect of chalcogen lone pairs to the aromatic rings, well-characterized radicals, including phenoxy and thiophenoxy, demonstrate that sulfur substitution for oxygen generally raises the electron affinity (EA). Here we report a coun...

A Radical Spin Ladder

Abstract The spin ladder model is an important platform bridging one-dimensional and two-dimensional magnetic systems, with its physical properties modulated by geometric configuration. As such, the S = 1/2 two-leg antiferromagnetic spin ladder has attracted attention due to its...

Sulfonic Acid‐Functionalized Zn Single‐Atom Catalysts With Dual Thiophilic and Sodiophilic Sites for High‐Performance Sodium−Sulfur Batteries

ABSTRACT Metal single‐atom catalysts (SACs) for sodium−sulfur (Na−S) batteries typically rely solely on thiophilic binding sites to interact with the polysulfide anions of sodium polysulfides (NaPSs), which intrinsically restricts their catalytic efficiency in sulfur redox reacti...
