FedAnomDetect a Clustered Federated Learning Framework for Robust Anomaly Detection With Enhanced Privacy and Communication Efficiency

IET Information Security, Volume 2026, Issue 1, 2026.
Anomaly detection in distributed environments poses significant challenges, particularly in balancing privacy, communication overhead, and detection accuracy. This paper presents FedAnomDetect, a novel federated learning (FL‐based framework designed for anomaly detection across large‐scale, distributed systems.

Cardiac incoordination induced by left bundle branch block: its relation with left ventricular systolic function in patients with and without cardiomyopathy

Cardiovascular Ultrasound, 2008
Background Although left bundle branch block (LBBB) alters the electrical activation of the heart, it is unknown how it might change the process of myocardial coordination (MC) and how it may affect the left ventricular (LV) systolic function.

Evaluation of Machine Learning Techniques for Denial‐of‐Service Attack Detection in Digital Information Exchange

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
Anomaly detection plays a critical role in mitigating cybersecurity threats, particularly Distributed Denial of Service (DDoS) attacks. This study evaluates the performance of tree‐based and ensemble learning models, including Decision Tree, Random Forest, and XGBoost, for classifying Snort log data, alongside the application of Isolation Forest for ...

Efficient but Elusive Rhizobia Fix Nitrogen in the Wild Legumes Bituminaria bituminosa and Coronilla Viminalis

Journal of Basic Microbiology, Volume 65, Issue 12, December 2025.
ABSTRACT In ecological restoration of degraded natural habitats, revegetation with wild native plants is a priority. Legumes play a key role in this process through nitrogen (N)‐fixing symbiosis with rhizobia, obtaining N for their growth and improving soil fertility, which benefits other nonleguminous plants in the environment. This study explores the
