Berry's phase in noncommutative spaces [PDF]

open access: yes, 2002
We introduce the perturbative aspects of noncommutative quantum mechanics. Then we study the Berry's phase in the framework of noncommutative quantum mechanics. The results show deviations from the usual quantum mechanics which depend on the parameter of

Thermodynamics for Trajectories of a Mass Point [PDF]

open access: yes, 2014
On the basis of information theory, a new formalism of classical non-relativistic mechanics of a mass point is proposed. The particle trajectories of a general dynamical system defined on an (1+n)-dimensional smooth manifold are treated geometrically as ...

Zebrafish epiboly: mechanics and mechanisms

open access: yesThe International Journal of Developmental Biology, 2010
Gastrulation involves of a series of coordinated cell movements to organize the germ layers and establish the major body axes of the embryo. One gastrulation movement is epiboly, which involves the thinning and spreading of a multilayered cell sheet. Epiboly plays a prominent role in zebrafish gastrulation and studies of zebrafish epiboly have provided

Mechanisms with Referrals: VCG Mechanisms and Multilevel Mechanisms [PDF]

open access: yesSSRN Electronic Journal, 2016
We study mechanisms for environments in which only some of the agents are directly connected to a mechanism designer and the other agents can participate in a mechanism only through the connected agents' referrals. Agents' network connections are private information, which can be strategically concealed by avoiding making referrals; while the mechanism

Imprinting Mechanisms [PDF]

open access: yesGenome Research, 1998
A number of recent studies have provided new insights into mechanisms that regulate genomic imprinting in the mammalian genome. Regions of allele-specific differential methylation (DMRs) are present in all imprinted genes examined. Differential methylation is erased in germ cells at an early stage of their development, and germ-line-specific ...

Mechanics and Mathematics in Ancient Greece

open access: yesEncyclopedia, 2022
This entry presents an overview on how mechanics in Greece was linked to geometry. In ancient Greece, mechanics was about lifting heavy bodies, and mathematics almost coincided with geometry.

Generalization of Classical Statistical Mechanics to Quantum Mechanics and Stable Property of Condensed Matter

open access: yes, 2005
Classical statistical average values are generally generalized to average values of quantum mechanics, it is discovered that quantum mechanics is direct generalization of classical statistical mechanics, and we generally deduce both a new general ...

Intermediate Filaments from Tissue Integrity to Single Molecule Mechanics

open access: yesCells, 2021
Cytoplasmic intermediate filaments (IFs), which together with actin and microtubules form the cytoskeleton, are composed of a large and diverse family of proteins.

Structural Design and Theoretical Analysis of Jetting Spin Type Lotus Root Digging Machine Based on CFD

open access: yesMachines, 2023
In order to solve the problem that digging lotus roots manually was high in labor intensity, low in efficiency and easy to damage lotus roots, and, in view of the defects of the high cost of existing digging lotus roots equipment and the cumbersome ...
