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 ...

Contrasting the synoptic drivers of the UK heatwaves of 1976, 2003, 2018 and 2022
Weather, EarlyView.UK summer heatwaves are dictated by the polar jet stream position and sea surface temperature (SST) variability, affecting the Summer North Atlantic Oscillation (SNAO) index. The SNAO can determine and influence the Central England Precipitation (CEP) and Central England Temperature (CET).

Wildlife Biology, EarlyView.Renewable energy is vital for reducing carbon emissions and yet its infrastructure poses challenges to biodiversity. While the impacts of wind power on bats and raptors are well‐studied, the effects on elusive species remain largely unknown. The Eurasian woodcock Scolopax rusticola, a nocturnal forest bird, performs characteristic courtship flights at ...

Reconstruction of vertical and L-shaped ancient Egyptian sundials and methods for measuring time
, 2014 The article presents the results of the study of design features of vertical and L-shaped ancient Egyptian sundials. With the help of astronomical methods were developed their models, based on which the reconstruction of a sundial was held.

Unraveling the symmetry of Al5C3N
Acta Crystallographica Section B, EarlyView.From experimental and theoretical techniques employed in this thorough reexamination of the structure of Al5C3N, the crystal structure is better described in centrosymmetric space group P63/mmc (No. 194) rather than in the previously reported noncentrosymmetric space group P63mc (No. 186).High‐temperature ceramic compound Al5C3N belongs to the scarcely

Flap Anatomies and Victorian Veils: Penetrating the Female Reproductive Interior
Gender &History, EarlyView.ABSTRACT This article examines the reappearance in the early nineteenth century of anatomical flapbooks in the context of obstetrical education in Britain, America and France. It asks why liftable paper flaps were reintroduced at this time after their disappearance from medical atlases in the eighteenth century.

Positioning and orienting a static cylindrical radio-reflector for wide field surveys
, 2012 Several projects in radioastronomy plan to use large static cylindrical reflectors with an extended lobe sampling a sector of the rotating sky. This study provides the exact mathematical expression of the transit time of a celestial object within the ...
