Pedo‐Climatic Controls on Soil Health Recovery Across Cultivation Chronosequences: Hydraulic Conductivity as a Potential Link Between Soil Structure, Microbial Biomass, and Nutrient Availability

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Long‐term cultivation can improve soil health, but recovery may not follow the same pathway across contrasting soil and climate conditions. A key unresolved question is whether soil health recovery is mainly associated with the release of physical–chemical constraints or with the gradual rebuilding of carbon, microbial biomass, and nutrient ...

NKX2‐1 Downstream Regulatory Structural Variants Explain a Substantial Proportion of Molecular Diagnoses in Patients With Benign Hereditary Chorea

open access: yesMovement Disorders, EarlyView.
Abstract Background NKX2‐1–related disorders (NKX2‐1‐RDs) classically present with a triad of neurological, endocrine, and pulmonary manifestations, including benign hereditary chorea. However, in a fraction of patients, NKX2‐1 coding variants are not detected, and variants outside the NKX2‐1 locus have been reported.

Survey of ultraviolet radiation-absorbing mycosporine-like amino acids in adult females of planktonic copepods

open access: yesAnnals of Tropical Research, 2002
The presence of UV-absorbing rnycosporine-like amino acids (MAAs) from nine planktonic calanoid copepod species were investigated. MAA concentrations from methanol extracts of adult females were analyzed by High Performance Liquid Chromatography (HPLC).

From Connections to Actions: When Do Government Ties Matter to Nonprofit Organizational Performance?

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT Nonprofit organizations are essential for public service delivery, yet the value of their government ties is contested. This study examines the mechanism that translates these connections into tangible results. We propose that political networking—the deliberate cultivation and use of official relationships—is the critical catalyst.

Unpacking the task of synthesis when weaving knowledge systems for biodiversity assessments

open access: yesPeople and Nature, EarlyView.
Abstract The pivot towards evidence‐based conservation since 2000 has inspired global environmental assessments to gather evidence across multiple knowledge systems, including through co‐production with Indigenous Peoples and local communities. Knowledge co‐production is highlighted as a strategy for transformative change towards a just future that ...

Deep Reinforcement Learning Based Autonomous Decision‐Making for Cooperative Uncrewed Aerial Vehicles: A Search and Rescue Real World Application

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This paper presents the first end‐to‐end framework that combines guidance, navigation, and centralized task allocation for multiple UAVs performing autonomous search‐and‐rescue (SAR) in GNSS‐denied indoor environments. A twin delayed deep deterministic policy gradient controller is trained with an artificial potential field (APF) reward that ...

River Ice Processes Modelling: A Comprehensive Review

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT River ice strongly influences hydrology, hydrodynamics, and ecosystems in cold regions, with an impact on flooding, hydropower generation, navigation, and aquatic habitats. Modeling river ice processes is therefore essential for both scientific understanding and operational management.

Students' Emotional Responses to Mistakes: An Ecological Momentary Assessment Study in University Chemistry Laboratory

open access: yesScience Education, EarlyView.
ABSTRACT This study explores students' emotions in the undergraduate chemistry laboratory, focusing particularly on emotional responses to making mistakes. Using an ecological momentary assessment design, we collected on‐task data from 240 students and 1635 learning situations during the laboratory sessions.

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

open access: yesSustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.
