What is the Nature of Chinese MicroBlogging: Unveiling the Unique Features of Tencent Weibo
Daifeng Li, Jingwei Zhang, Gordon Guo-zheng Sun +3
China has the largest number of online users in the world and about 20% internet users are from China. This is a huge, as well as a mysterious, market for IT industry due to variou…
Convex entropy, Hopf bifurcation, and viscous and inviscid shock stability
Blake Barker, Heinrich Freistühler, Kevin Zumbrun
We consider by a combination of analytical and numerical techniques some basic questions regarding the relations between inviscid and viscous stability and existence of a convex en…
Coxeter Cochain Complexes
Michael Larsen, Ayelet Lindenstrauss
We define the Coxeter cochain complex of a Coxeter group (G,S) with coefficients in a Z[G]-module A. This is closely related to the complex of simplicial cochains on the abstract s…
Behavior of periodic solutions of viscous conservation laws under localized and nonlocalized perturbations
Mathew A. Johnson, Pascal Noble, L. Miguel Rodrigues +1
We establish nonlinear stability and asymptotic behavior of traveling periodic waves of viscous conservation laws under localized perturbations or nonlocalized perturbations asympt…
Semiparametric zero-inflated modeling in multi-ethnic study of atherosclerosis (MESA)
Hai Liu, Shuangge Ma, Richard Kronmal +1
We analyze the Agatston score of coronary artery calcium (CAC) from the Multi-Ethnic Study of Atherosclerosis (MESA) using the semiparametric zero-inflated modeling approach, where…
Counting Dyck paths by area and rank
Saul A. Blanco, T. Kyle Petersen
The set of Dyck paths of length inherits a lattice structure from a bijection with the set of noncrossing partitions with the usual partial order. In this paper, we study the…
