Beam-Space Post-Doppler Reduced-Dimension STAP Based on Sparse Bayesian Learning

Remote Sensing
The space–time adaptive processing (STAP) technique can effectively suppress the ground clutter faced by the airborne radar during its downward-looking operation and thus can significantly improve the detection performance of moving targets. However, the

The Background Clutter Pattern Used in Figure–Ground Experiments

, 2013
The pattern used in figure–ground experiments (A) contains components of random frequency and phase, with 1/f statistics similar to those of natural scenes. It excites HS tangential neurons maximally (average of five recordings [B]), but has no effect on

A‐optimal model‐based design of experiments for processes with uncertain inputs

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Model‐based design of experiments (MBDoE) techniques are tools for selecting experimental conditions that enable accurate parameter estimation for mechanistic models. Most MBDoE approaches assume that the selected experimental conditions will be implemented perfectly, without uncertainties in the independent variables.

Bridging Theory and Prediction: A Hybrid SEM and Machine Learning Approach to Optimize Lean Construction for Megaproject Sustainability in China

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Construction megaprojects, large‐scale, complex, and capital‐intensive, are particularly prone to inefficiencies, cost overruns, delays, and environmental degradation due to fragmented workflows, stakeholder misalignment, and resource intensity.

Developing Transdiagnostic Single‐Session Interventions for University Students Experiencing Disordered Eating: A Mixed‐Method Co‐Design Study

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Many university students encounter barriers to timely support for disordered eating. Brief, scalable digital single‐session interventions (SSIs) may provide an engaging and accessible transdiagnostic pathway for early intervention where there is increased distress before a diagnosis emerges.

Adaptive polarization for rejection of ground clutter

, 1989
This paper reports some results on adaptive polarization techniques for rejection of ground clutter. The analysis is based on measurements carried out with a low resolution radar equipped with a diversity polarization receiver and recorded through a suitably designed acquisition system. The polarization behavior of the recorded ground clutter phenomena

The Relationship Among Climate Policy Uncertainty and Energy Markets: Fossil Versus Renewable and Low‐Carbon Assets

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper investigates the intricate relationship between climate policy uncertainty (CPU) and energy market dynamics, focusing on fossil‐based and renewable/low‐carbon energy assets. Utilising a comprehensive dataset spanning from April 1987 to December 2023, comprising monthly observations of CPU, stock market returns, spot oil prices and ...
