On the Slow-Time k-Space and its Augmentation in Doppler Radar Tomography

Sensors, 2020
Doppler Radar Tomography (DRT) relies on spatial diversity from rotational motion of a target rather than spectral diversity from wide bandwidth signals.

Long Baseline Stereovision for Automatic Detection and Ranging of Moving Objects in the Night Sky

Sensors, 2012
As the number of objects in Earth’s atmosphere and in low Earth orbit is continuously increasing; accurate surveillance of these objects has become important. This paper presents a generic, low cost sky surveillance system based on stereovision.

A Robust Space Target Extraction Algorithm Based on Standardized Correlation Space Construction

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
With the increasing amount of space debris in near-earth space, the surveillance of space has become more crucial to prevent potential space collisions. In an optical surveillance system, a multitude of debris with varying sizes, speeds, and intensities ...

Performance Analysis of Sensor Systems for Space Situational Awareness [PDF]

Journal of Astronomy and Space Sciences, 2017
With increased human activity in space, the risk of re-entry and collision between space objects is constantly increasing. Hence, the need for space situational awareness (SSA) programs has been acknowledged by many experienced space agencies.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.
