Partial regularity for flows of H-surfaces

open access: yesElectronic Journal of Differential Equations, 1997
This article studies regularity of weak solutions to the heat equation for H-surfaces. Under the assumption that the function H is Lipschitz and depends only on the first two components, the solution has regularity on its domain, except for a set of ...

Partial regularity for flows of H-surfaces, II

open access: yesElectronic Journal of Differential Equations, 1999
We study the regularity of weak solutions to the heat equation for H-surfaces. Under the assumption that the function $H:{Bbb R}^3 o {Bbb R}$ is bounded and Lipschitz, we show that the solution is $C^{2,alpha}$ on its domain, except for a set of measure ...

Energy quantization for approximate H-surfaces and applications

open access: yesElectronic Journal of Differential Equations, 2013
We consider weakly convergent sequences of approximate H-surface maps defined in the plane with their tension fields bounded in $L^p$ for p> 4/3, and establish an energy quantization that accounts for the loss of their energies by the sum of energies ...

Surface stability and H adsorption and diffusion near surfaces of W borides: a first-principles study

open access: yesNuclear Fusion, 2023
Understanding the behavior of tungsten boride (W _x B _y ) surfaces in a fusion reactor environment is an important topic since boronization is a common wall conditioning method used in fusion Tokamaks.

Deregulation of Factor H by Factor H-Related Protein 1 Depends on Sialylation of Host Surfaces

open access: yesFrontiers in Immunology, 2021
To discriminate between self and non-self surfaces and facilitate immune surveillance, the complement system relies on the interplay between surface-directed activators and regulators.

Evaluating the Utility of UV Lamps to Mitigate the Spread of Pathogens in the ICU

open access: yesApplied Sciences, 2020
Contaminated surfaces in a hospital serve as reservoirs for pathogen spread. The aim of this study was to evaluate UV lights in preventing the spread of a DNA tracer in an intensive care unit (ICU) through sterilization of highly touched surfaces.

An orthorhombic deformation family of Schwarz’ H surfaces

open access: yesTransactions of the American Mathematical Society, 2021
The classical H surfaces of H. A. Schwarz form a 1-parameter family of triply periodic minimal surfaces (TPMS) that are usually described as close relatives to his more famous P surface. However, a crucial distinction between these surfaces is that the P surface belongs to a 5-dimensional smooth family of embedded TPMS of genus three discovered by W ...

Canonical Coordinates and Natural Equation for Lorentz Surfaces in R13

open access: yesMathematics, 2021
We consider Lorentz surfaces in R13 satisfying the condition H2−K≠0, where K and H are the Gaussian curvature and the mean curvature, respectively, and call them Lorentz surfaces of general type. For this class of surfaces, we introduce special isotropic
