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

open access: yesHepatology, 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.

A Multiple Radar Approach for Automatic Target Recognition of Aircraft using Inverse Synthetic Aperture Radar [PDF]

open access: yes, 2018
Along with the improvement of radar technologies, Automatic Target Recognition (ATR) using Synthetic Aperture Radar (SAR) and Inverse SAR (ISAR) has come to be an active research area.

Uncertainty, entropy and decoherence of the damped harmonic oscillator in the Lindblad theory of open quantum systems [PDF]

open access: yes, 1999
In the framework of the Lindblad theory for open quantum systems, expressions for the density operator, von Neumann entropy and effective temperature of the damped harmonic oscillator are obtained.

Polarimetric ISAR autofocusing

open access: yesIET Signal Processing, 2008
Interest in polarimetric inverse synthetic aperture radar (ISAR) systems has been growing because of their capability to provide extra information about the imaged target compared with single polarisation ISAR systems. Target classification and recognition can be improved by exploiting full polarisation ISAR images.

State transitions as morphisms for complete lattices [PDF]

open access: yes, 1999
We enlarge the hom-sets of categories of complete lattices by introducing `state transitions' as generalized morphisms. The obtained category will then be compared with a functorial quantaloidal enrichment and a contextual quantaloidal enrichment that ...

Operational resolutions and state transitions in a categorical setting [PDF]

open access: yes, 1999
We define a category with as objects operational resolutions and with as morphisms - not necessarily deterministic - state transitions. We study connections with closure spaces and join-complete lattices and sketch physical applications related to ...

Asymptotic entanglement in open quantum systems

open access: yes, 2008
In the framework of the theory of open systems based on completely positive quantum dynamical semigroups, we solve in the asymptotic long-time regime the master equation for two independent harmonic oscillators interacting with an environment.

Continuous variable entanglement in open quantum dynamics

open access: yes, 2010
In the framework of the theory of open systems based on completely positive quantum dynamical semigroups, we give a description of the dynamics of entanglement for a system consisting of two uncoupled harmonic oscillators interacting with a thermal ...

Are species-area relationships from entire archipelagos congruent with those of their constituent islands? [PDF]

open access: yes, 2010
Copyright © 2010 Blackwell Publishing Ltd.AIM To establish the extent to which archipelagos follow the same species–area relationship as their constituent islands and to explore the factors that may explain departures from the relationship.

Sampling design may obscure species–area relationships in landscape-scale field studies [PDF]

open access: yes, 2020
We investigated 1) the role of area per se in explaining anuran species richness on reservoir forest islands, after controlling for several confounding factors.
