Integrating Satellite Data Into Meso‐Scale Habitat Modeling for Non‐Perennial Rivers and Streams

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Non‐perennial rivers and streams (NPRs) are widespread and projected to become more common, yet effective tools for their characterization and management remain limited. This study introduces a novel approach to assess aquatic habitat availability in NPRs, applied to a regulated reach of the Sangone River (Northern Italy).

An enhanced pricing model for truck transportation: a case study in Swedish forestry

International Transactions in Operational Research, Volume 33, Issue 2, Page 775-797, March 2026.
Abstract Determining freight rates for heavy trucks involves a detailed analysis of multiple cost factors, including time, distance, fuel, and other operational costs, which collectively contribute to the overall compensation for transportation services. However, actual remuneration is based on more simplified agreements.

Migration of Multimodal Deep Crustal Earthquake Swarm Beneath the Abu Volcano Group, Japan

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquakes in the lower crust, where high pressures and temperatures favor ductile deformation, are rare but occasionally occur beneath active volcanic centers, providing insights into deep magmatic processes. We analyze a deep crustal earthquake swarm (February–August 2025) of over 5,000 events beneath the Abu Volcano Group, Japan.

Mapping Skid Trails and Evaluating Soil Disturbance From UAV‐Based LiDAR Surveys in Mediterranean Forests

Land Degradation &Development, Volume 37, Issue 3, Page 1082-1092, 15 February 2026.
ABSTRACT Soil disturbance resulting from forest harvesting activities can have significant and lasting environmental consequences, particularly in sensitive ecosystems such as Mediterranean forests. Skid trails, the routes used by machinery to extract timber, are among the most critical areas of impact, and their detection is critical for assessing ...

Dynamically configurable architectures for multi-GNSS receiver

, 2017
This dissertation has focused on the development of dynamically configurable and programmable architectures for multi-GNSS receivers. The effect of RF front-end architecture and new characteristics of GNSS signals (modulation type, primary code generation, secondary code, required bandwidth and sampling frequency) on the complexity of the baseband ...
