Assessment of Soil Erosion Over Six Decades in a Long‐Term Experiment Using Fallout 137Cs and RUSLE: A South American Case Study

Land Degradation &Development, EarlyView.
ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...

Inspecting GNU radio applications with controlport and performance counters [PDF]

Proceedings of the second workshop on Software radio implementation forum, 2013
Due to differences in the operating system and the effects of sample rate on the computational load of a software radio, we have historically had a difficult time understanding the performance boundaries of software radio applications. This problem further leads to difficulties in debugging, optimization, and profiling analysis of both software radio ...

Physiologically based pharmacokinetic modeling and simulation of topiramate in populations with renal and hepatic impairment and considerations for drug–drug interactions

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 510-522, March 2025.
Abstract Topiramate (TPM) is a broad‐spectrum antiepileptic drug (AED) commonly prescribed for approved and off‐label uses. Routine monitoring is suggested for clinical usage of TPM in special population due to its broad side effect profile. Therefore, it is crucial to further explore its pharmacokinetic characteristics.

Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...
