Dignity's Dilemma: Categorical Objections to Autonomous Weapons and Their Pacifist Entailments
Journal of Applied Philosophy, EarlyView.ABSTRACT Dignity objections to autonomous weapon systems are prominent in contemporary military ethics, yet their theoretical foundations remain underexamined. This article reconstructs those foundations, showing what categorical dignity objections require to function as absolute prohibitions.

Recovery of great blue herons (Ardea herodias) within the Chesapeake Bay
The Journal of Wildlife Management, EarlyView.We surveyed great blue herons throughout the tidal reach of the Chesapeake Bay in 2013 and mapped 423 colonies supporting 15,094 pairs. The population has increased more than four‐fold since the mid‐1970s. Colony size has declined. Invasion of colonies by bald eagles may be driving a change in spatial structure.

Knowledge Integration in Professional Practices: Towards a New Transacting Approach
Knowledge and Process Management, EarlyView.ABSTRACT This paper advances understanding of knowledge integration across professional boundaries by examining how professionals coordinate action in two life‐ and time‐critical settings: aircraft maintenance and emergency healthcare. Building on established knowledge integration perspectives, the study investigates situations in which actors must ...

Fault Detection of Electric Motors via Symmetrized Dot Pattern‐Based Features
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This study proposes a novel symmetrized dot pattern (SDP) approach using designed SDP‐based features, extracted from transformed vibration signals, for fault detection. These features describe the compactness, inclination, and shape of the “snowflake” diagram distributions.

Prediction model for civil aircraft hard landing Informer neural network
Xibei Gongye Daxue XuebaoThe prediction of hard landing is of great significance to support the pilot's landing decision and ensure flight safety. Aiming at the short prediction time and poor explainability of the existing hard landing prediction models, the Informer hard ...
