The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

Astronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Arthroscopic Assisted Turf Toe Reconstruction With Knotless Suture Anchors and Suture Tape Augmentation

Arthroscopy Techniques, EarlyView.
Abstract Turf toe is a hallux metatarsophalangeal joint (MTPJ) injury seen in sports like football and soccer where the foot experiences axial load while fixed to the ground with the great toe hyperextended at the MTPJ. Depending on severity, turf toe can be quite devastating in athletes and can require operative intervention.

Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Corporate ESG Greenwashing: Does Regulatory Proximity Matter?

Business Strategy and the Environment, EarlyView.
ABSTRACT Environmental, social, and governance (ESG) greenwashing undermines sustainable development, yet the influence of regulatory proximity on oversight is understudied. By introducing the “distance decay effect” from geoeconomics into ESG misconduct research and using a sample of Chinese listed firms from 2009 to 2022, this study reveals a ...

Defining Remanufacturing: A Key Business Strategy Advancing Industrial Circularity

Business Strategy and the Environment, EarlyView.
ABSTRACT Remanufacturing is a key strategy in the circular economy, enabling substantial product value retention. However, inconsistent definitions across standards and legislation hinder global trade, core recovery and market acceptance. This study examines how remanufacturing is defined in laws and standards, and how these definitions impact industry
