Geochemical and granulometric fingerprints of 8200 years of westerly wind variability in inner‐fjord lake sediments from Svalbard

Boreas, EarlyView.
The Arctic is warming faster than any other region on Earth. As sea ice diminishes, the surface boundary conditions, such as roughness and air–sea coupling, change and open‐water fetch increases. This may enhance wind forcing on Arctic coasts. Lake sediments can record these changes through the deposition of wind‐blown grains and elements, offering ...

A global perspective on the annual cycles of whimbrels

Ibis, EarlyView.
Comparative analyses are central to understanding broad‐scale patterns in avian ecology, yet their application is often constrained by fragmented and uneven data availability. Recent advances in tracking technology have generated unprecedented insights into shorebird movements, resulting in numerous studies on single populations or flyways.

GNSS navigation interference disrupts telemetry tracking of raptors migrating between Europe and Africa

Ibis, EarlyView.
Global Navigation Satellite System (GNSS) interference in war conflict zones can disrupt wildlife tracking for research and conservation efforts. In 2023 and 2024, we tagged Black Kites Milvis migrans in Moldova and Kazakhstan, respectively, with telemetry loggers, tracked them until September 2025 and found that 20 out of the 24 Black Kites had ...

Periodontal Status of Type 1 Diabetes Mellitus and Healthy Pregnant Women: A Case–Control Pilot Study

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Aims This cross‐sectional ‘case–control’ pilot study aimed to compare the size of periodontal wounds, periodontal status and total inflammatory burden between pregnant women with type 1 diabetes mellitus (T1DM) and non‐diabetic pregnant women. Methods Fifteen T1DM pregnant women and 15 healthy pregnant women were included. Clinical parameters (

BLAC-Q4DIM: a bayesian optimization and LSTM driven adaptive clustering quasi-four-dimensional ionospheric model

Satellite Navigation
Accurate Slant Total Electron Content (STEC) modeling is essential for high-precision Global Navigation Satellite System (GNSS) positioning and space-weather monitoring. However, conventional Global Ionospheric Maps (GIMs) and fixed-parameter ionospheric

A novel mode of INS-aided BDS real-time high-rate and precise kinematic relative positioning between two moving platforms

Geo-spatial Information Science
For kinematic relative positioning users between two moving platforms, limited communication bandwidth and computation ability usually cannot support real-time transmission of high-rate (≥10 Hz) BeiDou Navigation Satellite System (BDS) data.

Contributions to the foundations of a safety case for the use of GNSS in railway environments [PDF]

, 2009
The use of GNSS in the railways for passenger information services and selective door opening is already commonplace but the advancement of this increasingly popular navigation technique into safety of life rail applications has been hindered by the ...

Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Multi‐year occupancy and habitat use in a threatened butterfly reintroduced onto a restored peatland

Restoration Ecology, EarlyView.
Abstract Introduction Over half of insect species reintroductions are unsuccessful, frequently because of insufficient habitat resources and a knowledge‐gap regarding the target species habitat requirements. Multi‐season occupancy models, seldom used with invertebrates, offer the opportunity to disentangle the effects of habitat suitability and ...

Investigating Effects in GNSS Station Coordinate Time Series

The vertical and horizontal displacements of the Earth can be measured to a high degree of precision using GNSS. Time series of Latvian GNSS station positions of both the EUPOS®-Riga and LatPos networks have been developed at the Institute of Geodesy and
