Eigenvalue Adjustment-Based STAP in Airborne MIMO Radar Under Limited Snapshots [PDF]

Sensors
The covariance matrix performs a vital role for space-time adaptive processing (STAP) in airborne multiple-input multiple-output (MIMO) radar. As is known, the clutter-plus-noise covariance matrix (CPNCM), reflecting the statistical characteristics of ...

STAP-2 facilitates insulin signaling through binding to CAP/c-Cbl and regulates adipocyte differentiation [PDF]

Scientific Reports
Signal-transducing adaptor protein-2 (STAP-2) is an adaptor molecule involved in several cellular signaling cascades. Here, we attempted to identify novel STAP-2 interacting molecules, and identified c-Cbl associated protein (CAP) as a binding protein ...

Stap voor stap de stilte betreden

Handelingen, 2018
Voor de gemiddelde hbo-student is stilte geen vanzelfsprekendheid. Er is altijd muziek, afleiding en sociale media. Een moment van stilte geeft juist ruimte aan vele, onrustig makende gedachten. Stilte geeft geen rust. En toch kan het oefenen van stilte

Potential of targeting signal-transducing adaptor protein-2 in cancer therapeutic applications [PDF]

Exploration of Targeted Anti-tumor Therapy
Adaptor proteins play essential roles in various intracellular signaling pathways. Signal-transducing adaptor protein-2 (STAP-2) is an adaptor protein that possesses pleckstrin homology (PH) and Src homology 2 (SH2) domains, as well as a YXXQ signal ...

Comparison of the performance of adaptive space-time processing against the background of alternative methods [PDF]

Biuletyn Wojskowej Akademii Technicznej, 2020
Description and successive stages of the STAP algorithm were characterized in this article. The ability to detect an object by using 6-element antenna array without space-time processing and using the STAP technique were compared and shown.

Random Matrix Theory-Based Reduced-Dimension Space-Time Adaptive Processing under Finite Training Samples

Remote Sensing, 2022
Space-time adaptive processing (STAP) is a fundamental topic in airborne radar applications due to its clutter suppression ability. Reduced-dimension (RD)-STAP can release the requirement of the number of training samples and reduce the computational ...

Space-Time Adaptive Processing by Employing Structure-Aware Two-Level Block Sparsity

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Traditional radar space-time adaptive processing (STAP) cannot efficiently suppress heterogeneous clutter because of a small number of independent and identically distributed training snapshots.

The Functional Properties and Physiological Roles of Signal-Transducing Adaptor Protein-2 in the Pathogenesis of Inflammatory and Immune Disorders

Biomedicines, 2022
Adaptor molecules play a crucial role in signal transduction in immune cells. Several adaptor molecules, such as the linker for the activation of T cells (LAT) and SH2 domain-containing leukocyte protein of 76 kDa (SLP-76), are essential for T cell ...

Signal-transducing adaptor protein-2 modulates T-cell functions

Exploration of Immunology, 2022
Immune responses are orchestrated by controlling the initiation, magnitude, and duration of various signaling pathways. Adaptor proteins act as positive or negative regulators by targeting critical molecules of signaling cascades.
