Numerical procedure for fluid-structure interaction with structure displacements limited by a rigid obstacle

open access: yesApplied and Computational Mechanics, 2017
A fixed point algorithmis proposed to solve a fluid-structure interaction problem with the supplementary constraint that the structure displacements are limited by a rigid obstacle.

Spatial Structure of Evolutionary Models of Dialects in Contact. [PDF]

open access: yesPLoS ONE, 2015
Phylogenetic models, originally developed to demonstrate evolutionary biology, have been applied to a wide range of cultural data including natural language lexicons, manuscripts, folktales, material cultures, and religions.

UNIFIED CONTACT STRUCTURE

open access: yesTamkang Journal of Mathematics, 1991
A necessary and sufficient condition that a $C^\infty$ manifold to admits anunified contad structure is established. A condition is obtained so that it becomes P-Sasakian. A linear connection in it is defined so its distributions are parallel.

Optimal contact definition for reconstruction of Contact Maps

open access: yesBMC Bioinformatics, 2010
Background Contact maps have been extensively used as a simplified representation of protein structures. They capture most important features of a protein's fold, being preferred by a number of researchers for the description and study of protein ...

b-Contact structures on tentacular hyperboloids

open access: yesJournal of Geometry and Physics, 2023
This paper connects two different approaches to the analysis of Hamiltonian dynamics on non-compact energy hypersurfaces - $b$-symplectic geometry with its singular symplectic form and Floer techniques for tentacular Hamiltonians. More precisely, we show how to equip tentacular hyperboloids with a $b$-contact structure.

The Effect of Patterned Micro-Structure on the Apparent Contact Angle and Three-Dimensional Contact Line

open access: yesFluids, 2021
The measurement of the apparent contact angle on structured surfaces is much more difficult to obtain than on smooth surfaces because the pinning of liquid to the roughness has a tremendous influence on the three phase contact line. The results presented

Structure-subsoil contact task - an iterative engineering realisation

open access: yesComputer Assisted Methods in Engineering and Science, 2023
The analytical formulation of an iterative procedure applied for structure- subsoil systems is presented in the paper. A physical and engineering interpretation has been given for the presented algorithm.

New relations between $G_2$-geometries in dimensions 5 and 7

open access: yes, 2016
There are two well-known parabolic split $G_2$-geometries in dimension five, $(2,3,5)$-distributions and $G_2$-contact structures. Here we link these two geometries with yet another $G_2$-related contact structure, which lives on a seven-manifold.

On nonexistence of Kenmotsu structure on аст-hypersurfaces of cosymplectic type of a Kählerian manifold

open access: yesДифференциальная геометрия многообразий фигур, 2019
Almost contact metric (аст-)structures induced on oriented hypersur­fa­ces of a Kählerian manifold are considered in the case when these аст-struc­tures are of cosymplectic type, i. e. the contact form of these struc­tu­res is closed. As it is known, the

On the optimal contact potential of proteins

open access: yes, 2007
We analytically derive the lower bound of the total conformational energy of a protein structure by assuming that the total conformational energy is well approximated by the sum of sequence-dependent pairwise contact energies.
