Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis

Hepatology, EarlyView., 2022
Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis. Abstract Background and Aims Nucleotide‐binding oligomerization domain‐like receptor‐family pyrin domain‐containing 3 (NLRP3) inflammasome activation has been shown to result in liver fibrosis.

Velocity-ISAR: On the application of ISAR techniques to multichannel SAR imaging [PDF]

2015 IEEE Radar Conference (RadarCon), 2015
The U.S. Naval Research Laboratory (NRL) Multichannel Synthetic Aperture Radar (MSAR) consists of multiple receive channels arranged along the flight direction and is unique in its ability to measure and correct for radial motion at each pixel in the scene. A well-known algorithm for performing MSAR imaging, and which have we applied for the first time

Multiview ISAR Imaging for Complex Targets Based on Improved SBR Scattering Model

International Journal of Antennas and Propagation, 2021
A novel multiview inverse synthetic aperture radar (ISAR) imaging method is proposed to simulate high-resolution and identifiable ISAR image of complex targets by handling large-angle and wide-bandwidth scattering data.

CLEAN Technique for Polarimetric ISAR [PDF]

International Journal of Navigation and Observation, 2008
Inverse synthetic aperture radar (ISAR) images are often used for classifying and recognising targets. To reduce the amount of data processed by the classifier, scattering centres are extracted from the ISAR image and used for classifying and recognising targets.

Needle detection and localisation for robot‐assisted subretinal injection using deep learning

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract Subretinal injection is a complicated task for retinal surgeons to operate manually. In this paper we demonstrate a robust framework for needle detection and localisation in robot‐assisted subretinal injection using microscope‐integrated Optical Coherence Tomography with deep learning.

GNSS-Based Passive Inverse SAR Imaging

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
The utilization of global navigation satellite system (GNSS) signals for remote sensing has been a hot topic recently. In this article, the feasibility of the GNSS-based passive inverse synthetic aperture radar (P-ISAR) is analyzed. GNSS-based P-ISAR can

Entanglement generation and evolution in open quantum systems [PDF]

, 2009
In the framework of the theory of open systems based on completely positive quantum dynamical semigroups, we study the continuous variable entanglement for a system consisting of two independent harmonic oscillators interacting with a general environment.

Axial Attitude Estimation of Spacecraft in Orbit Based on ISAR Image Sequence

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Attitude estimation is a significant task for monitoring noncooperative spacecraft in orbit. Inverse synthetic aperture radar (ISAR) is an effective method to obtain the structure, size, and attitude of spacecraft.
