When Nature Counts: Corporate Biodiversity Attention and Access to Bank Finance

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates whether corporate attention to biodiversity influences firms' access to bank loans, an overlooked question in the emerging biodiversity–finance literature. Using a novel, text‐based measure constructed from 446 biodiversity‐related keywords and applied to Chinese A‐share listed firms from 2000 to 2023, we show that ...

Asteroseismology of One of the Most Rapidly Rotating DBV Stars: EPIC 248705247

The Astrophysical Journal
We present a comprehensive analysis of oscillations of the helium-rich white dwarf DBV star EPIC 248705247 (SDSS J102106.69+082724.8). We extract the light curves from 79.7 days of K2 Campaign 14 data and identify 21 independent frequencies, including ...

A Determination of the Local Density of White Dwarf Stars

, 2001
The most recent version of the Catalog of Spectroscopically Identified White Dwarfs lists 2249 white dwarf stars. Among these stars are 109 white dwarfs that have either reliable trigonometric parallaxes or color-based distance moduli that place them at ...

Carbon Dots for Cancer Theranostics: Synthesis Strategies, Luminescence Properties, and Advances in Bioimaging‐Guided Diagnosis and Therapy

Chemistry – A European Journal, EarlyView.
Lighting up the path to precision oncology: This review comprehensively summarizes the rational design of carbon dots (CDs), elucidating how core size, surface chemistry, and heteroatom doping dictate their luminescence mechanisms. Special emphasis is placed on engineering NIR‐II emissive CDs for deep‐tissue imaging.

A White Dwarf Catalog from LAMOST DR11 Using Deep Learning

The Astrophysical Journal Supplement Series
White dwarfs, also referred to as degenerate dwarfs, represent the ultimate fate for the majority of stars in the Universe, unless their mass is large enough for them to evolve into black holes or neutron stars.

Speaking About Artificial Intelligence for Sustainability—How Employees’ Perception of Credibility Shapes Their Initial Attitudes Toward AI Adoption

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Companies increasingly claim to adopt artificial intelligence (AI) not only for economic but also for ecological and social purposes. However, in light of rising greenwashing, bluewashing, and ethics washing, the impact of the communicated rationale on employees' initial attitude toward AI introduction remains unclear.

AI‐Enhanced Laser Manufacturing: A Social Life Cycle Perspective From the White Goods Industry

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainable manufacturing transitions require companies to demonstrate not only environmental and economic benefits, but also measurable advances in corporate social responsibility (CSR). Therefore, we propose using a guideline‐based Social Life Cycle Assessment (S‐LCA) aligned with UNEP (2020) and ISO 14075 (2024) to evaluate the social ...

Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor

Contributions to Plasma Physics, EarlyView.
ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.
