Morphological adaptations of cervical vertebrae in plunge‐diving sulids

The Anatomical Record, EarlyView.
Abstract Foraging strategy frequently drives morphological diversification in birds. The plunge‐diving behavior of certain species makes the functional and ecological trade‐offs of variation in cervical vertebrae an especially intriguing question. This study compares cervical vertebrae across five plunge‐diving species and two non‐plunge‐diving species,

Do Big Data Analytics and Artificial Intelligence Enhance Corporate Sustainability? The Moderating Roles of Regulation and Management Support

Business Strategy and the Environment, EarlyView.
ABSTRACT We examine the effects of big data analytics (BDA) and artificial intelligence (AI) on corporate sustainability performance, specifically investigating the influence of regulatory pressure and top management support. Utilizing hierarchical regression analysis on questionnaire data from 220 Chinese manufacturing firms, we find that both BDA and

Ultrahigh Interfacial Thermal Conductance across GaN/BAs Interfaces via Atomic‐Level Engineering [PDF]

Advanced science
The integration of gallium nitride (GaN) with ultrahigh‐thermal‐conductivity boron arsenide (BAs) substrates represents a promising pathway for developing next‐generation high‐power devices. The heat dissipation capability of such integrated systems is fundamentally governed by thermal transport across GaN/BAs interfaces, and buffer layers such as ...

Photo‐Switchable FRET‐Enabled Flexible Luminescent Films for Multilevel Optical Security

Carbon Energy, EarlyView.
A light‐gated FRET composite integrates a Tb‐Phen donor and a spiropyran acceptor in a polyurethane matrix. Under 365 nm light, spiropyran is transformed into merocyanine, creating spectral overlap with Tb3+ emission and activating energy transfer. Visible light reverses the switch, restoring green emission and enabling reversible multilevel optical ...

Kaleidoscopic Electromagnetic Wave Manipulation via a Universal Reconfigurable Metasurface Platform

Electron, EarlyView.
A multidimensional reconfigurable metasurface enables independent control of the amplitude, phase, polarization, and spectral responses of reflected electromagnetic (EM) waves. Integrating spatial, polarization, and spectral manipulation within a single platform, it provides a versatile solution for intelligent EM systems, next‐generation wireless ...
