The influence of dimension eight operators on weak matrix elements
Mu dimension calculation matrix elements scale dimensional regularization
2014/12/22
I describe recent work with V. Cirigliano and E. Golowich on the effect of dimension eight operators on weak nonleptonic amplitudes. The basic mesage is that there is an inconsistency in the way that ...
Ghost Force Influence of A Qusicontinuum Method in Two Dimension
Ghost Force Influence A Qusicontinuum Method Two Dimension
2012/8/7
The error caused by the ghost force is studied for a quasicontinuum method with planar interface in two dimension. For a special case, we derive an analytical expression of the error, which is exploit...
Influence of realistic parameters on state-of-the-art LWFA experiments
Influence of realistic parameters state-of-the-art LWFA experiments Plasma Physics
2012/4/19
We examine the influence of non-ideal plasma-density and non-Gaussian transverse laser-intensity profiles in the laser wakefield accelerator analytically and numerically. We find that the characterist...
Hierarchical Consensus Formation Reduces the Influence of Opinion Bias
Hierarchical Consensus Formation Influence of Opinion Bias Physics and Society
2012/4/19
We study the role of hierarchical structures in a simple model of collective consensus formation based on the bounded confidence model with continuous individual opinions. For the particular variation...
On the Non-Progressive Spread of Influence through Social Networks
Non-Progressive Social Networks
2011/9/14
The spread of in uence in social networks is studied in two main categories: the progressive model and the non-progressive model (see e.g. the seminal work of Kempe, Kleinberg, and Tardos in KDD 2003)...
Momentum dependence of the symmetry potential and its influence on nuclear reactions
LQMD model ass splitting omentum-dependent potential
2011/7/20
A Skyrme-type momentum-dependent nucleon-nucleon force distinguishing isospin effect is parameterized and further implemented in the Lanzhou Quantum Molecular Dynamics (LQMD) model for the first time,...
Influence of the electrons on the stability of one-dimensional chains of metals
electrons one-dimensional chains metals
2011/8/4
Abstract: The physical model describing the influence of the electronic subsystem on the properties of one-dimensional chains of metal is presented. It is shown that depending on an interaction potent...
Co-evolution of Selection and Influence in Social Networks
Selection and Influence Social Networks
2011/9/14
Many networks are complex dynamical systems, where both attributes of nodes and topology of the network(link structure) can change with time. We propose a
model of co-evolving networks where both nod...
Influence of higher-order Kerr effect on conical emission from laser filaments in gases
higher-order Kerr effect ultrashort laser filaments
2011/8/31
We numerically investigate the conical emission (CE) from ultrashort laser filaments, both considering and disregarding the higher-order Kerr effect (HOKE). While the consideration of HOKE has almost ...
Financial factor influence on scaling and memory of trading volume in stock market
Financial facto trading volume stock market
2011/9/13
We study the daily trading volume volatility of 17,197 stocks in the U.S. stock markets during the period 1989–2008 and analyze the time return intervals between volume volatilities above a given th...
The reinforcing influence of recommendations on global diversification
The reinforcing influence Recommender systems
2011/8/26
Recommender systems are promising ways to filter the overabundant information in modern society. Their algorithms help individuals to explore decent items, but it is unclear how they allocate populari...
External field influence on semiflexible macromolecules: geometric coupling
External field semiflexible macromolecules
2010/12/24
We suggested a geometric approach to address the external field influence on the DNA molecules, described by the WLC model via geometric coupling. It consists in the introduction of the effective metr...
The influence of inhomogeneities on the large-scale expansion of the universe
the large-scale expansion universe
2010/12/27
The evolution of an inhomogeneous universe composed entirely of matter is followed from an early, nearly uniform state until the time when the inhomogeneities have begun to grow large. The particular...
Influence of Rotations on the Critical State of Soil Mechanics
Influence of Rotations Critical State of Soil Mechanics
2010/11/25
The ability of grains to rotate can play a crucial role on the collective behavior of granular media. It has been observed in computer simulations that imposing a torque at the contacts modi es the fo...
Influence of Mutual Drag of Light and Heavy Holes on conductivity of p-Silicon and p-Germanium
Mutual Drag of Light avy Holes
2010/11/25
Conductivity of p-Si and p-Ge is considered for two band model with due regard for mutual drag of light and heavy holes. It is shown that for small and moderate temperatures this drag sig-nificantly d...
