Dynamic mechanism of multiple bursting patterns in a whole-cell multiscale model with calcium oscillations

open access: yesJournal of Biological Dynamics, 2021
The dynamic mechanism of a whole-cell model containing electrical signalling and two-compartment Ca $ ^{2+} $ signalling in gonadotrophs is investigated.

On the dust tori in Palomar-Green quasars

open access: yes, 2004
The dust clouds in the torus of the quasar are irradiated by the central source, and the clouds at the inner radius of the torus re-radiate mostly in the near-infrared (NIR) wavebands.

Tracing KAM tori in presymplectic dynamical systems

open access: yes, 2012
We present a KAM theorem for presymplectic dynamical systems. The theorem has a " a posteriori " format. We show that given a Diophantine frequency $\omega$ and a family of presymplectic mappings, if we find an embedded torus which is approximately ...

Embedding torus in hexagonal honeycomb torus

open access: yesIET Computers & Digital Techniques, 2008
A number of parallel algorithms admit a static torus-structured task graph. Hexagonal honeycomb torus (HHT) networks are regarded as promising candidates for interconnection networks. In order to efficiently execute a torus-structured parallel algorithm on an HHT, it is essential to map the tasks to processors so that the communication overhead is ...

ON THE PROBLEM OF TORE DIFFEOMORPHISM EXTENSION AND ITS APPLICATIONS

open access: yesНаучный вестник МГТУ ГА, 2016
The construction of the extensions of a 2-torus diffeomorphism up to volume preserving diffeomorphism of solid tori is proposed. The construction is illustrated on the example of extension of diffeomorphism of action on the torus.

Nucleosynthesis in dynamical and torus ejecta of compact binary mergers

open access: yes, 2015
We present a comprehensive study of r-process element nucleosynthesis in the ejecta of compact binary mergers (CBMs) and their relic black-hole (BH)-torus systems.

Torus-Like Balloons

open access: yesJournal of Geometry and Symmetry in Physics, 2020
The concepts for inflatable deployable structures have been under development and evaluation for many years. Strangely enough only the Mylar balloon up to now has been described adequately. Here we provide the mathematical model and its analytical solution for the torus-like balloons.

Fractalization of Torus [PDF]

open access: yesProgress of Theoretical Physics, 1984
Summary: From the text: Various nonequilibrium systems show transition from torus to chaos. Its mechanism and critical phenomena have been studied extensively. Especially, the instability of phase motion has been analyzed in detail using a one-dimensional circle map. The amplitude behavior of the torus, however, has been less investigated.

Homological thickness and stability of torus knots

open access: yes, 2006
In this paper we show that the non-alternating torus knots are homologically thick, i.e. that their Khovanov homology occupies at least three diagonals. Furthermore, we show that we can reduce the number of full twists of the torus knot without changing ...
