Microexpressions are fast and spatially small facial expressions that are difficult to detect.Therefore, motion magnification techniques, which aim at amplifying and hence revealing subtle motion in videos, appear useful for handling such expressions.There are basically two main approaches, namely, via Eulerian or Lagrangian techniques.While the fi
This study investigates the applicability of using Computational Fluid Dynamics (i.e., CFD) simulations to evaluate the aerodynamic derivatives (i.e., AD) and Wind Structure Interaction (i.e., WSI) response of free vibrating bluff bodies.The study majorly focuses on three-dimensional simulations of a rigid cylinder with a square cross-section that
Background: Former historically disadvantaged social groups such as women, black people and those with disabilities are expected to participate in the skilled labour force that South Africa has pledged to produce for the 21st century.However, in the South African context, research widely neglects access of those into professional degrees in higher
The tumor suppressor gene p53 is frequently mutated in human breast cancer and is a marker for poor prognosis and resistance to chemotherapy.Transplantation of p53 null mouse mammary epithelium into syngeneic wild-type mice leads to normal mammary gland development followed by spontaneous mammary tumors that recapitulate many of the phenotypic, mol
Highly evolved carnivorous plants secrete digestive enzymes for degradation of trapped animals and absorb whole macromolecules from their prey by means of endocytosis.(1) Background: In the pitcher-plant family Sarraceniaceae, the production of enzymes is dubious and no evidence for endocytosis is known so far.(2) Methods: Heliamphora nutans, Darli
