Fastest mixing Markov chain on a path
Random walks symmetrical transition probability markov chain the uniform distribution the transfer matrix
font style='font-size:12px;'>
2015/8/10
We consider a random walk on a path with n nodes, with symmetric transition probabilities, i.e., the probability of making a transition between node i and node i+1 is the same as making a transition f...
Fastest mixing Markov chain on graphs with symmetries

2015/8/10
We show how to exploit symmetries of a graph to efficiently compute the fastest mixing Markov chain on the graph (i.e., find the transition probabilities on the edges to minimize the second-largest ei...

Over fifty years ago, Carl Eckart described the sequence of processes as a passive scalar is stirred and mixed in a turbulent flow (Eckart, 1948). At first, during the stirring phase, the variance of ...

We study enhancement of diffusive mixing on a compact Riemannian manifold by a fast incompressible flow. Our main result is a sharp description of the class of flows that make the deviation of the sol...

2015/7/14
Kelvin-Helmholtz (KH) instability, characterized by the distinctive
finite-amplitude billows it generates, is an important mechanism in the development
of turbulence in the stratified interior of ...

2015/7/8
We consider the problem of assigning transition probabilities to the edges of a path, so the resulting Markov chain or random walk mixes as rapidly as possible. In this note we prove that fastest mixi...
The Fastest Mixing Markov Process on a Graph and a Connection to a Maximum Variance Unfolding Problem
Markov connected graph edge tags transition rates

2015/7/8
We consider a Markov process on a connected graph, with edges labeled with transition rates between the adjacent vertices. The distribution of the Markov process converges to the uniform distribution ...

Frontogenesis and Frontal Progression of a Trapping-Generated Estuarine Convergence Front and Its Influence on Mixing and Stratification
Front Frontogenesis Trapping Convergence front Lateral circulation

Estuarine fronts are well known to influence transport of waterborne constituents such as phytoplankton and sediment, yet due to their ephemeral nature, capturing the physical driving mechanisms and t...
Modelling turbulent vertical mixing sensitivity using a 1-D version of NEMO
Modelling turbulent vertical mixing sensitivity NEMO1D

2015/3/5
Through two numerical experiments, a 1-D vertical model called NEMO1D was used to investigate physical
and numerical turbulent-mixing behaviour.

I review the present state of our knowledge about the masses and weak mixing elements of the u, d, s quarks. This is the written version of lectures given in the 1993 Theoretical Advanced Study Instit...

We discuss prospects for detecting the two charm-related phenomena of $D^0$-${\bar D}^0$ mixing and weak radiative decays of $D$ mesons ({\it e.g.} $D\to K^* + \gamma$). A general update of particle-a...

We show that recent calculations of ΔI=3/2 effects in nonleptonic hyperon decay induced by md-mu≠0 are subject to significant model dependence. [S0556-2821(97)04819-4]

We determine the η-η′ mixing angle via a procedure relatively independent of theoretical assumptions by simultaneously fitting η,η′ reactions involving the anomaly η,η′→γγ, π+π-γ. We extract reasonabl...
