Morphological Control of Aurophilic Chains of Gold(I) Dithiolate Dimers With Alkali and Alkali Earth Cations

Chemistry – A European Journal, EarlyView.
Luminescent coordination polymers of Group 1 (Li, K, Cs) and 2 (Mg─Ba) cations with gold(I) iso‐maleonitriledithiolate ({Au2[S2C = C(CN)2]}2−) units were prepared; 1‐D aurophilic chains are present in all cases. The structures strongly depend on cation charge and size, with N‐cyano coordination observed in the Gp 1 and larger Gp 2 cations. Increasingly

The Programming Optimization of Capacitorless 1T DRAM Based on the Dual-Gate TFET

Nanoscale Research Letters, 2017
The larger volume of capacitor and higher leakage current of transistor have become the inherent disadvantages for the traditional one transistor (1T)-one capacitor (1C) dynamic random access memory (DRAM).

Sleep deprivation aggravates hepatocytes steatosis and insulin resistance by regulating exosomal microRNAs

Interdisciplinary Medicine, EarlyView.
Sleep deprivation accelerates the progression of MASLD and IR by up‐regulating the expression of miR‐3572‐5p and down‐regulating the expression of miR‐183‐5p in circulating exosomes, thereby inhibiting fatty acid β‐oxidation and disrupting insulin signaling pathways. Abstract Sleep deprivation (SD) threatens human health and increases the prevalence of

A Bilayer Rare‐Earth/High‐κ Oxide Memristor for Energy‐Efficient Neuromorphic Intelligence

Small, EarlyView.
Interface‐engineered Gd2O3/HfO2 bilayer memristors demonstrate controlled filament formation, ultralow switching energy (∼13.56 pJ), and fast operation (∼350 ns) with a high ON/OFF ratio (∼107). The devices exhibit stable analog synaptic behavior and enable pattern recognition on Fashion‐MNIST, underscoring their promise for energy‐efficient ...

Register‐Efficient Linear‐Time Evaluation in the Bernstein Basis

Computer Graphics Forum, EarlyView.
Abstract We investigate the evaluation of points and derivatives of Bézier curves and surfaces on modern architectures, focusing on performance and guided by numerical error bounds. While the de Casteljau algorithm remains the reference for numerical robustness, its linear working‐set size imposes substantial register pressure on GPUs.

The circulation and distribution of classical Greek coinage

The Economic History Review, EarlyView.
Abstract From a sample of the most prominent Greek city‐states, data involving a total of 999 hoards and 160,007 coins from 550 to 300 BC were collected to discern the relative magnitudes, consistency of issue, and distribution of Classical Greek coinages.

Against the odds: Nesting specialization and foraging ecology provide insights into climate change responses in a mountain bee

Insect Conservation and Diversity, EarlyView.
A unique high‐elevation Exoneura bee defies typical elevation‐driven declines in bee activity, nesting exclusively in dead branches of snow gums near the alpine tree line. Nesting and foraging are tightly linked to snow gum presence, with most activity occurring within 30 m of these trees. Biophysical modelling indicates the bee's thermally constrained
