Determining Significant Morphological and Hemodynamic Parameters to Assess the Rupture Risk of Cerebral Aneurysms
(SPRINGER HEIDELBERG, 2019)
Hemodynamics and morphology are recognized as major factors in the rupture risk of cerebral aneurysms, and exploration of their relationship is necessary to establish a method that can be employed by clinicians to assess ...
On sign-changeable interaction in FLRW cosmology
(SPRINGER, 2019)
We investigate an interacting two-fluid model in a spatially flat Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe, when the energy transfer between these two dark components is produced by a factorizable nonlinear ...
An Empirical Study of Exhaustive Matching for Improving Motion Field Estimation
(MDPI, 2018)
Optical flow is defined as the motion field of pixels between two consecutive images. Traditionally, in order to estimate pixel motion field (or optical flow), an energy model is proposed. This energy model is composed of ...
Crystalline structure and grain boundary identification in nanocrystalline aluminum using K-means clustering
(IOP Publishing Ltd., 2020-09)
K-means clustering was carried out to identify the atomic structure of nanocrystalline aluminum. For this purpose, per-atom physical quantities were calculated bymeans ofmolecular dynamics simulations, such as the potential ...
Understanding Chemical Reactivity in Extended Systems: Exploring Models of Chemical Softness in Carbon Nanotubes
(PEKING UNIV PRESS, 2018)
Chemical reactivity towards electron transfer is captured by the Fukui function. However, this is not well defined when the system or its ions have degenerate or pseudo-degenerate ground states. In such a case, the first-order ...
Co-existence and switching between fast and Omega-slow wind solutions in rapidly rotating massive stars
(OXFORD UNIV PRESS, 2018)
Most radiation-driven winds of massive stars can be modelled with m-CAK theory, resulting in the so-called fast solution. However, the most rapidly rotating stars among them, especially when the rotational speed is higher ...
