Limits imposed by liquid/surface interactions in the determination of tortuosity in mesopores
(Elsevier Science, 2020-10-01)
The restricted mobility of different liquids, polar and non-polar, were studied by means of 1H NMR diffusion and Larmor frequency dependent relaxation measurements, upon confinement in mesoporous silica with mean pore sizes ...
Novel deep learning method for coronary artery tortuosity detection through coronary angiography
(Nature Research, 2024)
Quantificação da tortuosidade de vasos sanguíneos: definições e influência das etapas de realce e segmentação
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2021-11-08)
Morphological features of blood vessels can be used as markers of several pathologies affecting the tissues of organisms. Among these features, tortuosity displays a vital role in the study and diagnostic of conditions ...
Assessing the long-term effects of zero-tillage on the macroporosity of Brazilian soils using X-ray Computed Tomography
(Elsevier B.V., 2019-03-01)
Zero-tillage (ZT) is being increasingly adopted globally as a conservationist management system due to the environmental and agronomic benefits it provides. However, there remains little information on the tillage effect ...
Diffusion of Water and Electrolytes in Mesoporous Silica with a Wide Range of Pore Sizes
(American Chemical Society, 2018-02)
The diffusion of alkaline chlorides (LiCl, KCl, and CsCl) and water in mesoporous silica samples with pore sizes covering the range from micropores (2 nm) up to mesopores larger than 30 nm have been measured by resorting ...
Neural Network Prediction of the Trabecular Bone Mechanical Competence Parameter
(Springer, 2014-01-01)
The mechanical competence parameter (MCP) has been defined to grade the trabecular bone fragility based on the principal component analysis (PCA) evaluated in terms of volume fraction, connectivity, tortuosity and Young ...
Estimating the mechanical competence parameter of the trabecular bone: A neural network approach
(2016-06-01)
Introduction: The mechanical competence parameter (MCP) of the trabecular bone is a parameter that merges the volume fraction, connectivity, tortuosity and Young modulus of elasticity, to provide a single measure of the ...
VesselVAE: Recursive Variational Autoencoders for 3D Blood Vessel Synthesis
(Universidad Torcuato Di Tella, 2023)
We present a data-driven generative framework for synthesizing blood vessel 3D geometry. This is a challenging task due to the
complexity of vascular systems, which are highly variating in shape, size,
and structure. ...
Alterações vasculares no fundo de olho em pacientes pediátricos com hipertensão portal
(Universidade Federal de São Paulo, 2023-04-27)
Objetivo: Avaliar o exame do fundo de olho de pacientes pediátricos com doença hepática crônica ou com trombose da veia porta de acordo com a presença de hipertensão portal definida clinicamente pelos critérios diagnósticos ...
