Digital disease management programme reduces chronic gastrointestinal symptoms among racially and socially vulnerable populations

open access: yesBMJ Open Gastroenterology
Objective Considerable disparities exist in access to gastrointestinal (GI) care and digestive outcomes across gender, racial, and socioeconomic groups. We evaluated (1) whether adults with chronic GI symptoms from diverse demographic groups would use a ...

The Cylinder Product and Cylinder Matrices

open access: yesJournal of Algebra, 1999
Let \(A\) be a coquasitriangular (CQT) bialgebra over a field \(k\). Let \(\sigma\) denote the invertible braid form on \(A\otimes A\). \textit{T.~tom Dieck} and \textit{R.~Häring-Oldenburg} introduced CQT bialgebras with a cylinder form [Forum Math. 10, No. 5, 619-639 (1998; Zbl 0974.17017)].

Curve shortening by short rulers

open access: yesESAIM: Proceedings and Surveys, 2014
The aim is to construct a straight line between the two endpoints of a rectifiable curve using only a ruler, which is too short to connect them directly.

Conjugate Effects of Heat and Mass Transfer on Natural Convection Flow Across an Isothermal Horizontal Circular Cylinder With Chemical Reaction

open access: yesNonlinear Analysis, 2007
Natural convection flow across an isothermal cylinder immersed in a viscous incompressible fluid in the presence of species concentration and chemical reaction has been investigated. The governing boundary layer equations are transformed into a system of

Wrinkling of Elastic Cylinders With Material Properties Varying in Radial Direction

open access: yesFrontiers in Mechanical Engineering, 2022
Although the instability of graded elastic cylinders has been analyzed by many researchers, most of them focused on the core-shell cylinders and film-substrate structures with inhomogeneous Young’s modulus.

Large eddy simulation of flow past a stationary and controlled oscillating circular cylinder at RE=5500 [PDF]

open access: yes, 2013
Vortex shedding from a stationary cylinder and transversely oscillating circular cylinder in a uniform flow at a Reynolds number of 5500 is numerically studied by three-dimensional Large Eddy Simulation (LES). The filtered equations are discretised using

Study on Parameterization of Vortex-Induced Vibration Energy Harvester in Agricultural Environment

open access: yesAgriEngineering, 2020
In many special agricultural environments, many wireless sensors have a problem of power supply selection. Energy harvesting in the agricultural environment based on vortex-induced vibration (VIV) has the potential to solve the problem. In this paper, an

Shifted Legendre Collocation Method for the Solution of Unsteady Viscous-Ohmic Dissipative Hybrid Ferrofluid Flow over a Cylinder

open access: yesNanomaterials, 2021
A numerical treatment for the unsteady viscous-Ohmic dissipative flow of hybrid ferrofluid over a contracting cylinder is provided in this study. The hybrid ferrofluid was prepared by mixing a 50% water (H2O) + 50% ethylene glycol (EG) base fluid with a ...
