We examined changes in the diversity of herbaceous plant species at colony ( ) sites of the plains vizcacha Lagostomus maximus following local extinctions of this species in semi-arid scrub of central Argentina. These large rodents live in social groups, share a communal burrow system, and forage in a common home range around the burrow system. Through intense herbivory, vizcachas create large ...

• The main idea is to obtain a generalized tensor description of the transition probability matrix or the transition rate matrix • N finite automata. One automaton is used to model one component. • The state space is included into the Cartesian product of the state space of the automata.

We give a polynomial-time algorithm for learning latent-state linear dynamical systems without system identification, and without assumptions on the spectral radius of the system’s transition matrix. The algorithm extends the recently introduced technique of spectral filtering, previously applied only to systems with a symmetric transition matrix, using a novel convex relaxation to allow for th...

The transition from aquatic to terrestrial locomotion was a key development in vertebrate evolution. We present a spinal cord model and its implementation in an amphibious salamander robot that demonstrates how a primitive neural circuit for swimming can be extended by phylogenetically more recent limb oscillatory centers to explain the ability of salamanders to switch between swimming and walk...

In this paper we treat some fractal and statistical features of the DNA sequences. First, a fractal record model of DNA sequence is proposed by mapping DNA sequences to integer sequences, followed by R/S analysis of the model and computation of the Hurst exponents. Second, we consider transition between the four kinds of bases within DNA. The transition matrix analysis of DNA sequences shows th...
