Partial Dynamical Symmetry and Mixed Dynamics [PDF]

open access: yesPhysical Review Letters, 1996
Partial dynamical symmetry describes a situation in which some eigenstates have a symmetry which the quantum Hamiltonian does not share. This property is shown to have a classical analogue in which some tori in phase space are associated with a symmetry which the classical Hamiltonian does not share.

Classical dynamics as constrained quantum dynamics [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2003
We show that the classical mechanics of an algebraic model are implied by its quantizations. An algebraic model is defined, and the corresponding classical and quantum realizations are given in terms of a spectrum generating algebra. Classical equations of motion are then obtained by constraining the quantal dynamics of an algebraic model to an ...

Oscillations of First Order Delay Dynamic Equations

open access: yes, 2006
Stavroulakis, Ioannis/0000-0002-4810-0540Consider the first order linear delay dynamic equation of the forms x(Delta)(t) + p(t)x(tau(t)) = 0. (E) New oscillation criteria are established which contain well-known criteria for delay differential and ...

Contractive self maps of alpha-psi-type on fuzzy metric spaces

open access: yes, 2020
[EN] We introduce and discuss a notion of $\alpha -\psi $-contractive self map for fuzzy metric spaces in the sense of Kramosil and Michalek, which allows us to prove a fixed point theorem that constitutes a fuzzy counterpart of a relevant fixed point ...

Dynamical footprints of hurricanes in the tropical dynamics

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2023
Hurricanes—and more broadly tropical cyclones—are high-impact weather phenomena whose adverse socio-economic and ecosystem impacts affect a considerable part of the global population. Despite our reasonably robust meteorological understanding of tropical cyclones, we still face outstanding challenges for their numerical simulations.

The Dynamic Synapse [PDF]

open access: yesNeuron, 2013
The constant dynamic movement of synapses and their components has emerged in the last decades as a key feature of synaptic transmission and its plasticity. Intramolecular protein movements drive conformation changes important to transduce transmitter binding into signaling. Constant cytoskeletal rearrangements power synapse shape movements.

The Cauchy problem for generalized abstract Boussinesq equations

open access: yes, 2016
In this paper, the existence and uniqueness of solution of the Cauchy problem for abstract Boussinesq equations is obtained. By applying this result, the Wentzell-Robin type mixed problem for Boussinesq equations and the Cauchy problem for finite or ...

Dynamic Virtual Organizations, or Not so Dynamic? [PDF]

open access: yes, 2002
Expectations created by the early rapid developments in virtual organizations, hoping to resolve the main challenges in the area and continuous emergence of new related facilities are still far from full materialization. Being a multidisciplinary area that requires the participation of experts in ICT, theory of organizations, sociology, economy, law ...
