Unprecedented Migratory Bird Die‐Off: A Citizen‐Based Analysis on the Spatiotemporal Patterns of Mass Mortality Events in the Western United States

GeoHealth, 2021
Extensive, severe wildfires, and wildfire‐induced smoke occurred across the western and central United States since August 2020. Wildfires resulting in the loss of habitats and emission of particulate matter and volatile organic compounds pose serious ...

Real‐Time and Rapid Dynamic Missile Identification Utilizing a TiOx Memristor Array

Advanced Intelligent Systems, EarlyView.
Real‐time missile target identification is demonstrated using an artificial intelligence model based on step‐weighted long–short‐term memory networks and a TiOx memristor array. The approach classifies five projectile types with enhanced early‐stage prediction through data augmentation and custom training strategies. Achieving 94.4% accuracy, the model

Arrival and Peak Abundance of Barn Swallows Hirundo rustica in Three Regions of South Africa in Relation to Climate Indices, Deduced from Bird Atlas Data

Birds
For three regions of South Africa (Greater Gauteng, Greater Cape Town and Greater Durban) with the greatest coverage by bird atlas (SABAP2) fieldwork, we related arrival timing and abundance in each region of a long-distance migrant bird, the Barn ...

Winter Conditions Influence Biological Responses of Migrating Hummingbirds

, 2016
Conserving biological diversity given ongoing environmental changes requires the knowledge of how organisms respond biologically to these changes; however, we rarely have this information. This data deficiency can be addressed with coordinated monitoring

Provenance does matter: links between winter trophic segregation and the migratory origins of European robins [PDF]

, 2016
Amongst migratory species, it is common to find individuals from different populations or geographical origins sharing staging or wintering areas.

Compact Modeling of Volatile‐Switching Electrochemical Metallization Memory Cells by Means of the Electromotive Force

Advanced Intelligent Systems, EarlyView.
A volatile‐switching compact model of electrochemical metallization memory cells for neuromorphic architecture is developed and validated by reliable reproduction of device characterization measurements: I−V sweeps, SET kinetics, relaxation dynamics.

Climate in Europe and Africa Sequentially Shapes the Spring Passage of Long-Distance Migrants at the Baltic Coast in Europe

Diversity
Since the 1980s, earlier European springs have led to the earlier arrival of migrant passerines. We predict that arrival is related to a suite of climate indices operating during the annual cycle (breeding, autumn migration, wintering, spring migration ...

Assessing Angiogenic Properties In Vitro or In Ovo of Pre‐Crosslinked Alginate‐Dialdehyde‐Gelatin Hydrogels Incorporating Boron‐Doped Mesoporous Bioactive Glass Particles

Advanced NanoBiomed Research, EarlyView.
This study examines the influence of boron‐doped mesoporous bioactive glass nanoparticles (MBGN) blended in cast and 3D‐printed pre‐crosslinked alginate‐dialdehyde‐gelatin (ADA‐GEL). Addition of 0.5% and 1% MBGN did not negatively affect the viability of human umbilical vein endothelial cells (HUVECs), or the sprouting of HUVEC spheroids.

Estimates of aerial vertebrate mortality at wind farms in a bird migration corridor and bat diversity hotspot

Global Ecology and Conservation, 2020
Three major flyways of the Nearctic – Neotropical bird migration system converge at the coastal plains of the Isthmus of Tehuantepec, Mexico. Approximately one million vultures and raptors traverse the area during the autumn migration season, and more ...
