Penn Researchers Demonstrate How to Control Liquid Crystal Patterns（图）
Penn Researchers Liquid Crystal Patterns
2017/11/23
When Lisa Tran set out to investigate patterns in liquid crystals, she didn’t know what to expect. When she first looked through the microscope, she saw dancing iridescent spheres with fingerprint-lik...
First open-access data from large collider confirm subatomic particle patterns（图）
First open-access data large collider subatomic particle patterns
2017/10/25
In November of 2014, in a first, unexpected move for the field of particle physics, the Compact Muon Solenoid (CMS) experiment — one of the main detectors in the world’s largest particle accelerator, ...
University of Utah mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory, call...
QUANTIFYING THE ECOLOGICAL PATTERNS OF URBAN DENSIFICATION THROUGH MULTIPLE ENDMEMBER SPECTRAL MIXTURE ANALYSIS, LANDSCAPE METRICS, AND FUZZY LOGIC

This paper introduces an integrative methodology that has been developed to measure temporal changes in urban morphology based
on the techniques of multiple endmember spectral mixture analysis (MESM...
Atomic structure of a single large biomolecule from diffraction patterns of random orientations
X-ray free electron lasers Single particle x-ray diffraction Orientation Structure reconstruction
2012/4/20
The short and intense pulses of the new X-ray free electron lasers, now operational or under construction, may make possible diffraction experiments on single molecule-sized objects with high resoluti...
Epidemic Variability in Hierarchical Geographical Networks with Human Activity Patterns
Epidemic Variability Hierarchical Geographical Networks Human Activity Patterns Social and Information Networks
2012/4/19
Recently, some studies have revealed that non-Poissonian statistics of human behaviors stem from the hierarchical geographical network structure. On this view, we focus on epidemic spreading in the hi...
Depth Profile of Optically Recorded Patterns in Light-Sensitive Liquid Crystal Elastomers
Depth Profile Optically Recorded Patterns Light-Sensitive Liquid Crystal Elastomers
2011/8/11
Abstract: We investigated nonlinear absorption and photobleaching processes in a liquid crystal elastomer (LCE) doped with light-sensitive azobenzene moiety. A conventional one-dimensional holographic...
Behavior patterns of online users and the effect on information filtering
bipartite networks reshuffling process information filtering
2011/8/3
Abstract: Understanding the structure and evolution of web-based user-object bipartite networks is an important task since they play a fundamental role in online information filtering. In this paper, ...
The emergence of complex patterns in online human communication

2011/8/31
Social media have become essential conduits in the worldwide exchange of ideas, opinions and consumer marketing. Complex networks are important tools for analyzing the information ow in many aspects o...
We analyze a model of mutually-propelled laments suspended in a two-dimensional solvent. The
system undergoes a mean- eld isotropic-nematic transition for large enough lament concentrations and the...
Analysis of patterns formed by two-component diffusion limited aggregation
nalysis of patterns two-component diffusion limited aggreg
2010/11/18
We consider diffusion limited aggregation of particles of two different kinds. It is assumed that a particle of one kind may adhere only to another particle of the same kind. The particles aggregate o...

In topological insulators (TI), strong spin-orbit coupling results in non-trivial scattering
processes of the surface states, whose effects include suppressed back scattering1, 2, 3, 4 weak anti-loca...
Branching Patterns and Stepped Leaders in an Electric-Circuit Model for Creeping Discharge
Branching Patterns Stepped Leaders Electric-Circuit Model
2010/4/21
We construct a two-dimensional electric circuit model for creeping discharge. Two types of discharge, surface corona and surface leader, are modeled by a two-step function of conductance. Branched pat...
From thunderous mountain landscapes viewed from above to the erratic trajectories of Brownian motion, fractal patterns exist at many scales in nature. Physicists believe that fractals also exist in th...

2010/4/7
A set of travelling wave solutions to a hyperbolic generalization of the convection-reaction-diffusion is studied by the methods of local nonlinear alnalysis and numerical simulation. Special attentio...
