Study suggests at least 11 fish species are able to walk on land（图）
fish species walk land
2020/9/25
A team of U.S. National Science Foundation-funded scientists has identified at least 11 species of fish suspected to have land-walking abilities.The findings are based on CT scans and a new evolu...
A theory that uses the mathematics of a drunken walk describes ecological invasions better than waves, according to Tim Reluga, associate professor of mathematics and biology, Penn State.The ability t...
NON-PERTURBATIVE APPROACH TO RANDOM WALK IN MARKOVIAN ENVIRONMENT
Random Walk Random environment CLT Gibbs
2015/9/29
The study of random walk in random evolving environment has attracted much attention lately.
The basic idea is that, due to the time mixing properties of the environment, the CLT should hold
in any ...
Central Limit Theorem for Excited Random Walk in the Recurrent Regime
Recurrent Regime Excited Random Walk
2015/9/29
We consider excited random walk on a strip. We assume that the
cookies are positive and that the total expected drift per site is less than 1/L where
L is the width of the strip. We prove a quenched...

The method is to nd the asymptotic behavior of the ergodic sums of L1
functions for linear
ows on the in nite staircase surface.
Our methods also provide a new proof of J. Beck's central limit th...
Pre-reptile may be earliest known to walk upright on all fours（图）
Network Control Noise Lead the Way
2015/9/25
A newly published analysis of the bones of Bunostegos akokanensis, a 260-million-year-old pre-reptile, finds that it likely stood upright on all fours like a cow or a hippo, making it the earliest kno...
We study the rate of convergence of symmetric random walks on finite
groups to the uniform distribution. A notion of moderate growth is introduced
that combines with eigenvalue techniques to give sh...
LOCAL-TO-GLOBAL PRINCIPLES FOR THE HITTING SEQUENCE OF A ROTOR WALK
LOCAL-TO-GLOBAL PRINCIPLES HITTING SEQUENCE ROTOR WALK
2015/8/14
In rotor walk on a finite directed graph, the exits from each vertex follow a prescribed periodic sequence. Here we consider the case of rotor walk where a particle starts from a designated source ver...

range rotor walk
2015/8/14
In a rotor walk the exits from each vertex follow a prescribed periodic sequence. On an infinite Eulerian graph embedded periodically in Rd, we show that any simple rotor walk, regardless of rotor mec...

A SUPER-CLASS WALK ON UPPER-TRIANGULAR MATRICES。
CORVALLIS, Ore. – Humans and some of our hominid ancestors such as Homo erectus have been walking for more than a million years, and researchers are close to figuring out how we do it.
