Direct Measurement of the Protein Response to An Electrostatic Perturbation That Mimics the Catalytic Cycle in Ketosteroid Isomerase
hydroperoxide lipids GUV photosensitization methylene blue
2016/5/25
Understanding how electric fields and their fluctuations in the active site of enzymes affect efficient catalysis represents a critical objective of biochemical research. We have directly measured the...
Vibrational Stark Effects of Nitriles II. Physical Origins of Stark Effects from Experiment and Perturbation Models
platinum titania catalyst flame synthesis one-step oxidation screening
2016/5/23
Vibrational Stark effects, which are the effects of electric fields on vibrational spectra, were measured previously for the C−N stretch mode of several small nitriles, yielding difference dipol...

Local Response Topological Order External Perturbation
2016/1/23
We study the behavior of the Re ′nyi entropies for the toric code subject to a variety of different perturbations, by means of 2D density matrix renormalization group and analytical methods. We find t...
The thin film equation with non zero contact angle:A singular perturbation approach
thin film equation non zero contact angle singular perturbation approach
2015/10/15
In this paper we prove the existence of weak solutions for the thin film equation with prescribed non zero contact angle and for a large class of mobility coefficients, in dimension 1. The existence o...
ABILITIES OF DEMETER SATELLITE IN OBSERVATION OF PHYSICAL SIGNATURES PERTURBATION OF IONOSPHERE ASSOCIATED WITH SEISMIC ACTIVITIES
Seismic Activities Physical Signatures
2015/9/8
Earthquake is one of the most horror natural hazards that cause a lot of damage.
So, humans always have been looking for approaches to predict it so that they can
reduce its damage. For this purpose...
Perturbation analysis of entrainment in a micromechanical limit cycle oscillator
Resonance MEMS Bifurcation Perturbation
2015/8/27
We study the dynamics of a thermo-mechanical model for a forced disc shaped, micromechanical limit cycle oscillator.The forcing can be accomplished either parametrically, by modulating the laser beam ...
Robust stability of a linear multivariable system, in the sense of robustness under multiplicative transfer function perturbation, is necessarily preserved under sufficiently small perturbations in th...
Taking Perturbation to the Accuracy Frontier: A Hybrid of Local and Global Solutions
Dynare Perturbation Hybrid Accuracy Numerical methods Approximation
2015/7/21
Local (perturbation) methods compute solutions in one point and tend to deliver far lower accuracy levels than global solution methods. We develop a hybrid
method that solves for some policy function...
Wellsprings of Creation:How Perturbation Sustains Exploration in Mature Organizations
Disruption Innovation and Management Business Processes Opportunities Creativity
2015/4/22
Organizations struggle to balance simultaneous imperatives to exploit and explore, yet theorists differ as to whether exploitation undermines or enhances exploration. The debate reflects a gap: the mi...
Matter-wave solitons in the presence of collisional inhomogeneities: Perturbation theory and the impact of derivative terms
Dynamic soliton atomic scattering length nonlinear dynamic
2014/12/24
We investigate the dynamics of matter-wave solitons in the presence of a spatially varying atomic scattering length and nonlinearity. The dynamics of bright and dark solitary waves is studied using th...
Recently methods have been developed which exploit the chiral symmetry of QCD in order to make rigorous contact with low energy particle physics phenomenology. In these lectures we present a pedagogic...
