Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract We analyze Interferometric Synthetic Aperture Radar (InSAR) and Global Navigation Satellite System (GNSS) data to characterize ground deformation and dike opening associated with the May 2021 Nyiragongo eruption. Despite documented eruptions in 1977 and 2002, Nyiragongo's magmatic system and its interaction with regional rifting remain poorly ...

A fully digital model for Kalman filters
, 2010 The Kalman filter is a mathematical method, whose purpose is to process noisy measurements in order to obtain an estimate of some relevant parameters of a system.

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Ocean bottom pressure recordings are a key observation for both ocean circulation and seafloor geodesy. New self‐calibrating instruments may solve a long‐time issue of instrument drift, allowing new high precision observations. However, instruments on the seafloor may settle over days to months, potentially contaminating results.

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Monitoring lake and reservoir water levels is critical for water resource management and flood risk mitigation. We integrate Sentinel‐3A/B and ICESat‐2 altimetry to reconstruct monthly water levels (2018–2023) for 7,433 lakes and reservoirs (>5 km2) across Asia and estimate their storage variations.

Distributed SE(d) Formation Control of Multi‐Agent Systems Using Relative Measurements
International Journal of Robust and Nonlinear Control, Volume 36, Issue 1, Page 100-116, 10 January 2026.ABSTRACT This study develops a solution to the distributed SE(d) formation control problem of multi‐agent systems using only relative measurements between agents. In this problem, poses, that is, orientations and positions, of the agents are expected to achieve desired ones.

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem
Ecological Solutions and Evidence, Volume 7, Issue 1, January/March 2026.We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...
