Autonomous time-frequency cropping and feature-extraction algorithms for classification of LPI radar modulations [PDF]
, 2006 Three autonomous cropping and feature extraction algorithms are examined that can be used for classification of low probability of intercept radar modulations using time-frequency (T-F) images.

Executive Function and Entrepreneurial Opportunity Exploitation Under Risk and Uncertainty
Strategic Change, Volume 35, Issue 2, Page 217-239, March 2026.ABSTRACT This study examines how executive functions shape entrepreneurial opportunity exploitation under different knowledge environments. Drawing on Knight's distinction between risk and uncertainty, we conducted a vignette experiment with 200 working adults.

Radar Maxima: Calibrated Area‐Based Probabilistic Forecasts for Heavy Precipitation
Meteorological Applications, Volume 33, Issue 2, March/April 2026.Radar Maxima is a calibrated area‐based probabilistic forecast product for heavy precipitation. Radar precipitation within 40 km neighbourhoods is aggregated to statistically upscale ICON‐D2‐EPS. The product is designed to overcome inherent limitations of point‐based forecasts, which often yield low probabilities for extreme events. ABSTRACT We present,

Tocolytic agents and the failure to improve neonatal outcomes
Pregnancy, Volume 2, Issue 2, March 2026.Abstract Premature delivery has long been a major problem in obstetrics. Increased perinatal morbidity and mortality as well as substantial health care costs, both short and long term, have driven the efforts to combat this complication. While multiple agents have been studied over the last 70 years leading to hundreds of publications and involving ...

Fortschritte der Physik, Volume 74, Issue 3, March 2026.ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.
