Proximal Ligand Motions in H93G Myoglobin
resonance Raman heme myoglobin hemoglobin ligand switch
2016/5/24
Resonance Raman spectroscopy has been used to observe changes in the iron-ligand stretching frequency in photoproduct spectra of the proximal cavity mutant of myoglobin H93G. The measurements compare ...
On Hausdorff dimension of oscillatory motions in three body problems
Hausdorff dimension oscillatory motions three body problems
2015/9/25
We show that for the Sitnikov example and for the restricted planar circular 3–body problem the set of oscillatory motions often has maximal Hausdorff dimension. Also, we construct Newhouse domains fo...
Collapse modes of structures under strong motions of earthquake
collapse mode damage concentration P-d effect flexible-stiff mixed structure
2015/9/25
Under strong motion earthquakes, structures receive various types of damage. The most fatal damage is the loss of lateral strengths of a structure. The loss of lateral resistance causes a total collap...
In three experiments we tried to mask the motions of human gait. We represented human walkers as a set of 11 computer-generated elements on a display monitor, moving as a nested hierarchy of motions t...
The Equations of Oceanic Motions has two primarily pedagogical aims: to establish rigorously the equations of oceanic motions, including the equilibrium thermodynamics of seawater and the molecular tr...
Each observable ballistic phenomenon of a spin-stabilized rifle bullet can be explained in terms of the acceleration of gravity and the total aerodynamic force acting on that bullet. In addition to th...
Large Harnack inequalities, Kobayashi distances and holomorphic motions
Large Harnack inequalities Kobayashi distances holomorphic motions Complex Variables
2012/4/18
We prove some generalizations and analogies of Harnack inequalities for pluriharmonic, holomorphic and "almost holomorphic" functions. The results are applied to the proving of smoothness properties o...
Forward-Backward Doubly Stochastic Differential Equations with Brownian Motions and Poisson Process
Forward-backward doubly stochastic differential equations stochastic analysis random measure Poisson process
2011/11/7
The existence and uniqueness for solution of backward doubly stochastic differential equations with Brownian motions and Poisson process and that of forward-backward doubly stochastic differential equ...
Perturbed stellar motions around the rotating black hole in Sgr A* for a generic orientation of its spin axis
Perturbed stellar motions rotating black hole generic orientation spin axis
2011/10/17
Empirically determining the averaged variations of the orbital parameters of the stars orbiting the Supermassive Black Hole (SBH) hosted by the Galactic Centre (GC) in Sgr A* is, in principle, a valua...
Functional ergodic theorems of site-dependent branching Brownian motions in R
Functional ergodic theorem branching Brownian motion site-dependence Levy Khintchine representation
2011/9/21
Abstract: In this paper, we studied the functional ergodic limits of the site-dependent branching Brownian motions in R. The results show that the limiting processes are non-degenerate if and only if ...
Peculiar motions, accelerated expansion and the cosmological axis
Peculiar motions accelerated expansion cosmological
2011/10/12
Peculiar velocities change the expansion rate of any observer moving relative to the smooth Hubble flow. As a result, observers in a galaxy like our Milky Way can experience accelerated expansion with...
A Central Limit Theorem for a sequence of Brownian motions in the unit sphere in $\mathbb{R}^{n}$
Central Limit Theorem Brownian motion in the unit sphere in Rn OrnsteinUhlenbeck processes
2011/9/13
Abstract: We use a Stochastic Differential Equation satisfied by Brownian motion taking values in the unit sphere $S_{n-1}\subset\mathbb{R}^{n}$ and we obtain a Central Limit Theorem for a sequence of...

Abstract: Empirically determining the averaged variations of the orbital parameters of the stars orbiting the Supermassive Black Hole (SBH) hosted by the Galactic Centre (GC) in Sgr A* is, in principl...
Subtle pH differences trigger single residue motions for moderating conformations of calmodulin
intracellular pH sensing conformational change energy landscape perturbation response scanning molecular dynamics
2011/8/4
Abstract: This study reveals the essence of ligand recognition mechanisms by which calmodulin (CaM) controls a variety of Ca2+ signaling processes. We study eight forms of calcium-loaded CaM each with...
Discrete Integrable Systems and Hodograph Transformations Arising from Motions of Discrete Plane Curves
Discrete Integrable Systems Hodograph Transformations Motions of Discrete Plane Curves
2011/9/29
Abstract: We consider integrable discretizations of some soliton equations associated with the motions of plane curves: the Wadati-Konno-Ichikawa elastic beam equation, the complex Dym equation, and t...
