On the geometry of Hamiltonian vector fields [PDF]
It is known that vector fields play an important role in many areas of mathematics and technology, in particular, in the theory of dynamical systems. Hamiltonian dynamical systems are generated by Hamiltonian vector fields. The paper studies the geometry

The Ergodicity and Sensitivity of Nonautonomous Discrete Dynamical Systems
Let (E,h1,∞) be a nonautonomous discrete dynamical system (briefly, N.D.D.S.) that is defined by a sequence (hj)j=1∞ of continuous maps hj:E→E over a nontrivial metric space (E,d).

Theoretical studies for dynamical function of practical inerters
This study aims to establish the fundamental theory of function of the practical inerters. Inerter is effective component for mechanical vibration system to control vibration frequency characteristics. Many studies related to inerter had been examined in

Calculation of effective pump dose in X-ray-pump/X-ray-probe experiments
In pump–probe experiments on solid materials performed within ultrafast X-ray science, the energy deposited by an X-ray pump pulse in the sample has a non-uniform spatial distribution.

Singular boundary value problems for quasi-differential equations
Solutions are obtained of boundary value problems for Lny+f(x,L0y,…,Ln−2y), satisfying L2y(0)=Ln−1y(1)=0, 0≤i≤n−2, where Li, denotes the ith quasiderivative, and where f(x,y1,…,yn−1) has singularities at yi=0, 1≤i≤n−1.

Molecular dynamics study of tridymite [PDF]
Structural changes in tridymite have been investigated by molecular dynamics simulation. Two thermal processes were carried out, one cooling from the high-temperature hexagonal structure of tridymite (HP-tridymite) and the other heating from the low-temperature monoclinic structure of tridymite (MX1-tridymite).

Synchronization of dissipative dynamical systems driven by non-Gaussian Lévy noises
Dynamical systems driven by Gaussian noises have been considered extensively in modeling, simulation, and theory. However, complex systems in engineering and science are often subject to non-Gaussian fluctuations or uncertainties.

Extreme value laws in dynamical systems under physical observables [PDF]
Extreme value theory for chaotic deterministic dynamical systems is a rapidly expanding area of research. Given a system and a real function (observable) defined on its phase space, extreme value theory studies the limit probabilistic laws obeyed by ...

Magnetoencephalography in the study of brain dynamics [PDF]
To progress toward understanding of the mechanisms underlying the functional organization of the human brain, either a bottom-up or a top-down approach may be adopted. The former starts from the study of the detailed functioning of a small number of neuronal assemblies, while the latter tries to decode brain functioning by considering the brain as a ...

Neutron frequency windows and the protein dynamical transition
Proteins undergo an apparent dynamical transition on temperature variation that has been correlated with the onset of function. The transition in the mean-square displacement, ∆r2 , that is observed using a spectrometer or computer simulation, depends on
