Decoupling the Retention–Energy Trade‐Off Through Structural Reorganization of Synaptic Polyelectrolytes for Nonvolatile Neuromorphic Devices

ABSTRACT Electrolyte‐gated synaptic transistors (EGSTs) are promising ion‐mediated artificial synapses, but their performance is constrained by a retention–energy trade‐off. Enhancing long‐term memory (LTM) retention often requires enhanced ion accessibility, which can induce exc...

Electrical‐Programming‐Free Neural Crossbars Enabled by Photochemical Weight Patterning

ABSTRACT Hardware neural networks based on crossbar architectures require reliable implementation of multilevel synaptic weights, yet conventional electrical programming often suffers from programming interference, device variability, and write–verify overhead. Here, we present e...

Anomaly Localization and Classification of Jaw Cysts and Tumours Using Anatomy-Conditioned Diffusion on Panoramic Radiographs

Objectives Accurate localization and classification of jaw cysts and tumours on panoramic radiographs are important for timely referral and treatment planning but remain challenging due to overlapping anatomy, heterogeneous lesion appearances, and dental restorations. This study...

Sprayable MXene Hydrogels With Composition‐Driven Interfacial Stabilization and on‐Skin Gelation for Conformal Postsurgical Photothermal Therapy

ABSTRACT Oxidative degradation of Ti 3 C 2 T x MXene in aqueous and biological environments remains a persistent obstacle to its long‐term use in biomedical applications, yet the role of the surrounding polymer matrix in governing this process has received little systematic atten...

Bond–slip model for estimating the friction coefficient of pretensioned strands considering end slip

Abstract In pretensioned prestressed concrete members, the transfer length of the strand exhibits significant variability, but current design equations do not fully account for the effects of various factors. However, the end slip value of the strand exhibits a strong correlation...

Data-driven framework for calibrated thermal comfort assessment and thermal sensation prediction of construction workers during summer

Purpose Construction workers are highly vulnerable to summer heat stress, yet thermal comfort assessment is often constrained by limited site-specific meteorological data. This study aims to develop a calibration framework that adjusts publicly available meteorological data to ap...

Local Acidity as a Corrosiveness Descriptor of Fluorinated Ether Solvents in Lithium–Metal Batteries

ABSTRACT Electrolyte engineering based on solvent fluorination has proven effective for stabilizing lithium (Li) metal batteries by weakening the Li + ‐solvent interaction. However, the influence of fluorination on the chemical reactivity of an electrolyte toward Li metal remains...

Feature-Level Cloud Guidance for Sentinel-2 Imagery Reconstruction in SAR-Optical Fusion

Cloud contamination remains a major limitation in optical remote sensing because clouds and cloud shadows obscure or distort land-surface reflectance information.Sentinel-2 imagery provides rich multispectral information for land-cover mapping, environmental monitoring, agricultu...

Joint Multiplier–Adder Approximation with Flag-Based Error Recovery for BF16 Digital Compute-in-Memory

Digital computing-in-memory (DCIM) provides deterministic floating-point computation but incurs substantial area and power overhead from replicated mantissa multipliers and adder trees. This work proposes an error-recoverable BF16 DCIM arithmetic unit that jointly approximates a...

Domain-Specific Cognitive Concordance in Older Married Couples

Importance Spousal similarity in late-life cognition has been reported, but whether concordance differs across cognitive domains remains unclear. Objective To examine whether cognitive concordance among older married couples is domain specific by comparing real couples with demog...

Civil Servants' Compliance with Conflict‐of‐Interest Regulation: Evidence from a List Experiment

ABSTRACT While regulatory governance scholarship has paid significant attention to the normative importance of ethics reform in government, empirical evidence on compliance remains scant. Drawing on insights from the social value activation model and behavioral ethics, this study...

Comparison of diestrus duration and temporal gene expression patterns in vaginal smear samples from pseudopregnant rats induced by sonic vibration or mating with vasectomized males

BACKGROUND: Induction of pseudopregnancy is a prerequisite for successful embryo transfer in rats. Conventionally, pseudopregnancy is induced by mating females with vasectomized males. Although effective, this method requires surgical preparation and maintenance of sterile males...

Geosynthetic Applications and Design Methods for Paved and Unpaved Road Systems in Minnesota: Review of Current Practice

Geosynthetics are widely used in pavement systems in multiple applications, including base and subgrade stabilization, reduction of layer intermixing and moisture, and mitigation of shrink/swell-related distresses. However, the current geosynthetic classification system and guide...

The Shadow of Success: Rural Differentiation and the ‘Produced Poor’ in a Malawi Agricultural Development Project

ABSTRACT Smallholder agricultural projects are central to rural poverty reduction, yet their distributional outcomes remain underexplored. Using mixed methods (qualitative interviews and an 804‐household survey analysed via PSM‐DID), this paper examines a decade‐long Malawi proje...
