Modeling radiative transfer in tropical rainforest canopies: sensitivity of simulated albedo to canopy architectural and optical parameters

Anais da Academia Brasileira de Ciências, 2011
This study evaluates the sensitivity of the surface albedo simulated by the Integrated Biosphere Simulator (IBIS) to a set of Amazonian tropical rainforest canopy architectural and optical parameters.

On Perfect Matchings and tilings in uniform Hypergraphs

, 2018
In this paper we study some variants of Dirac-type problems in hypergraphs. First, we show that for $k\ge 3$, if $H$ is a $k$-graph on $n\in k\mathbb N$ vertices with independence number at most $n/p$ and minimum codegree at least $(1/p+o(1))n$, where $p$

Ubiquitin‐specific protease 25 improves myocardial ischemia–reperfusion injury by deubiquitinating NLRP3 and negatively regulating NLRP3 inflammasome activity in cardiomyocytes

Clinical and Translational Medicine, Volume 15, Issue 2, February 2025.
Abstract Background Myocardial ischemia/reperfusion injury (MI/RI) restricts the effect of myocardial reperfusion therapy and lacks effective prevention and treatment methods. Deubiquitinating enzymes (DUBs), especially members of the ubiquitin‐specific protease (USP) family of DUBs, are key proteins in the ubiquitination modification process and play

Pluripotency, differentiation, and reprogramming: A gene expression dynamics model with epigenetic feedback regulation

, 2015
Characterization of pluripotent states, in which cells can both self-renew and differentiate, and the irreversible loss of pluripotency are important research areas in developmental biology. In particular, an understanding of these processes is essential

Filter Design Using Ultra‐Miniaturised Substrate‐Integrated Coaxial Cavity

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
The proposed substrate‐integrated coaxial cavity (SICC) comprises two dielectric substrates with three metal layers. The top and bottom metal layers form the cavity's broadside walls, and the middle is a circular patch that shorts to the bottom wall and to an embedded split CPW ring, respectively, through a blind‐via ring and three blind vias.

Post‐translational modifications of proteins in cardiovascular diseases examined by proteomic approaches

The FEBS Journal, Volume 292, Issue 1, Page 28-46, January 2025.
Mass spectrometry (MS)‐based proteomics has proven to be a powerful method capable of mapping, localizing and quantifying post‐translational modifications (PTMs). PTMs play regulatory roles in protein functions/activities and the recognition of PTMs specific to cardiovascular pathologies is crucial for usage in clinics.

Pyrosequencing-based analysis reveals a novel capsular gene cluster in a KPC-producing Klebsiella pneumoniae clinical isolate identified in Brazil

BMC Microbiology, 2012
Background An important virulence factor of Klebsiella pneumoniae is the production of capsular polysaccharide (CPS), a thick mucus layer that allows for evasion of the host's defense and creates a barrier against antibacterial peptides.

Detection of the Entropy of the Intergalactic Medium: Accretion Shocks in Clusters, Adiabatic Cores in Groups

, 2000
The thermodynamics of the diffuse, X-ray emitting gas in clusters of galaxies is linked to the entropy level of the intra cluster medium. In particular, models that successfully reproduce the properties of local X-ray clusters and groups require the ...
