Solitary waves in discrete media with four-wave mixing
Vector discrete model nonlinear coupling transverse electric field the transverse magnetic and linear polarization
font style='font-size:12px;'>
2014/12/25
In this paper, we examine in detail the principal branches of solutions that arise in vector discrete models with nonlinear intercomponent coupling and four wave mixing. The relevant four branches of ...
Mobility of discrete solitons in quadratically nonlinear media
Lattice soliton flow nonlinear discrete second-order soliton
font style='font-size:12px;'>
2014/12/25
We study the mobility of solitons in lattices with quadratic (χ(2), alias second-harmonic-generating) nonlinearity. Using the notion of the Peierls-Nabarro potential and systematic numerical simulatio...
Modulational instability in nonlinearity-managed optical media
Numerical simulation of the instability cubic nonlinear optical dielectric glass air
font style='font-size:12px;'>
2014/12/25
We investigate analytically, numerically, and experimentally the modulational instability in a layered, cubically nonlinear (Kerr) optical medium that consists of alternating layers of glass and air. ...
Highly nonlinear solitary waves in heterogeneous periodic granular media
Numerical simulation of highly nonlinear solitary wave dimer and trimer one-dimensional particle lattice structure
font style='font-size:12px;'>
2014/12/24
We use experiments, numerical simulations, and theoretical analysis to investigate the propagation of highly nonlinear solitary waves in periodic arrangements of dimer (two-mass) and trimer (three-mas...

2014/11/27
In the last decade, arts and culture have been placed at the center of attention when discussing economic growth. In particular, studies on the “creative class” have been using arts and culture as an ...
Estimating Network Degree Distributions Under Sampling: An Inverse Problem, with Applications to Monitoring Social Media Networks
Estimating Network Degree Distributions Sampling An Inverse Problem Applications Monitoring Social Media Networks
font style='font-size:12px;'>
2013/6/14
Networks are a popular tool for representing elements in a system and their interconnectedness. Many observed networks can be viewed as only samples of some true underlying network. Such is frequently...
Casimir Friction Between Dense Polarizable Media
Casimir Friction Dense Polarizable Media
font style='font-size:12px;'>
2013/6/17
The present paper - a continuation of our recent series of papers on Casimir friction for a pair of particles at low relative particle velocity - extends the analysis so as to include dense media. The...
THE CORPORATE GOVERNANCE ROLE OF THE MEDIA: EVIDENCE FROM RUSSIA
THE CORPORATE GOVERNANCE ROLE THE MEDIA RUSSIA
font style='font-size:12px;'>
2010/11/5
We study the effect of media coverage on corporate governance by focusing on Russia in the period 1999-2002. This setting offers us three ideal conditions for such a study: plenty of corporate governa...
Marketing the Anti-Drug Message: Media, Source and Message Credibility Interactions
the Anti-Drug Message Media, Source and Message Credibility Interactions
font style='font-size:12px;'>
2010/1/15
This paper investigates the role of media, source and message credibility in the process of preventing/reducing drug use. An original contribution of the study is that this investigation was conducted...
Internet Dependency Relations and Online Consumer Behavior:A Media System Dependency Theory Perspective on Why People Shop, Chat, and Read News Online
Internet Dependency Relations Online Consumer Behavior A Media System Dependency Theory Perspective
font style='font-size:12px;'>
2009/12/2
This study introduces Internet Dependency Relations (IDR) as a predictor of online consumer activities. IDR is based on the theoretical perspective of Media System Dependency theory, which postulates ...

The Influence Of Media Attention Towards Family-Friendly Practices: Was New Zealand’s Paid Parental Leave a family-friendly fashion whose time had come?
Paid Parental family-friendly fashion
font style='font-size:12px;'>
2009/9/23
The attention given to family-friendly practices in the New Zealand media has not been
explored from a management fashions perspective. This theory suggests that media attention
towards management...
Majorizing multiplicative cascades for directed polymers in random media
Directed polymers random environment strong disorder generalized multiplicative cascades
font style='font-size:12px;'>
2009/6/12
In this note we give upper bounds for the free energy of discrete directed polymers in random media. The bounds are given by the so-called generalized multiplicative cascades from the statistical theo...
Branching diffusions, superdiffusions and random media
spatial branching processes branching diffusions measure-valued processes superprocesses catalytic branching Law of Large Numbers
font style='font-size:12px;'>
2009/5/18
Spatial branching processes became increasingly popular in the past decades, not only because of their obvious connection to biology, but also because superprocesses are intimately related to nonlinea...
