Weakly imposed boundary conditions for shear-rate dependent non-Newtonian fluids: application to cardiovascular flows

Autor: Soonpil Kang, Sharbel Nashar, Elizabeth R. Livingston, Arif Masud

Publikováno v: Mathematical Biosciences and Engineering, Vol 18, Iss 4, Pp 3855-3886 (2021)

This paper presents a stabilized formulation for the generalized Navier-Stokes equations for weak enforcement of essential boundary conditions. The non-Newtonian behavior of blood is modeled via shear-rate dependent constitutive equations. The bounda

Publikováno v: Experimental and Clinical Psychopharmacology. 30:525-535

Caffeine is regularly used by college students to enhance mood and academic performance. Although high doses confer risk for negative consequences, moderate doses of caffeine may lead to acute improvements in mood and cognitive functioning. Notably,

Negative Affect Regulation and Marijuana Use in College Students: Evaluating the Mediating Roles of Coping and Sleep Motives

Autor: Nicholas R, Livingston, Eleftherios, Hetelekides, Adrian J, Bravo, Alison, Looby

Publikováno v: Journal of Psychoactive Drugs. 55:203-212

Negative affect regulation models suggest that marijuana may be used to reduce negative affect. Extant research has provided support for these models, indicating that specific motives for marijuana use, particularly coping motives (i.e., using to all
