In this note we study automata recognizing birecurrent sets. A set of words is birecurrent if the minimal partial DFA recognizing this set and the minimal partial DFA recognizing the reversal of this set are both strongly connected. This notion was introduced by Perrin, and Dolce et al. provided a characterization of such sets. We prove that deciding whether a partial DFA recognizes a birecurre...

Pairwise comparisons are used in a wide variety of decision situations where the importance alternatives should be measured on numerical scale. One popular method to derive priorities is based right eigenvector multiplicative pairwise comparison matrix. We consider two monotonicity axioms this setting. First, increasing an arbitrary entry matrix not allowed result counter-intuitive rank reversa...

The effect of theta pulse stimulation (TPS) on pentylenetetrazol (PTZ)-induced long-term potentiation of population spikes (PS) was studied in the hippocampal CA1 in vitro. A transient PTZ application produced a long-lasting enhancement of PS amplitude. A 3-min episode of TPS delivered at a higher intensity produced complete reversal of the PTZ potentiation when delivered during the last minute...

A time-reversal-violating spin-correlation coefficient in the total cross section for polarized neutrons incident on a tensor rank-2 polarized target is calculated by assuming a time-reversal-noninvariant, parity-conserving “five-fold” interaction in the neutron-nucleus optical potential. Results are presented for the system n + Ho for neutron incident energies covering the range 1–20 MeV. From...

Different types of dominance hierarchies reflect different social relationships in primates. In this study, we clarified the hierarchy and social relationships in a one-male unit of captive Rhinopithecus bieti observed between August 1998 and March 1999. Mean frequency of agonistic behaviour among adult females was 0.13 interactions per hour. Adult females exhibited a linear hierarchy with a re...

background: the effects of aqueous extract of fadogia agrestis stem at the doses of 18, 36, and 72 mg/kg body weight on alloxan-induced toxicity was investigated in wistar rats. methods: in total, 35 rats of both sexes (132.80±7.22g) were randomized into five groups (a-e): animals in group a received 0.5 ml of distilled water orally on daily basis for 15 days while the alloxanized rats in group...

We extend a microscopic theory of polarization and magnetization to include the spin degree freedom electrons, introducing general orbit coupling Zeeman interaction term in Hamiltonian. At finite frequencies including spin, magnetoelectric polarizability tensor is replaced by two separate tensors, one that relates \textbf{P} magnetic field \textbf{B} \textbf{M} electric \textbf{E}. When combine...

In this paper we study the structure of standard Einstein solvmanifolds of arbitrary rank. Also the validity of a variational method for finding standard Einstein solvmanifolds is proved.

A minimal Kitaev-Gamma model has been recently investigated to understand various Kitaev systems. In the one-dimensional chain, an emergent SU(2)$_1$ phase and a rank-1 spin ordered with $O_h\rightarrow D_4$ symmetry breaking were identified using non-Abelian bosonization numerical techniques. However, puzzles near antiferromagnetic region finite Gamma interaction remained unresolved. Here we f...

A d-dimensional zero-one matrix A avoids another d-dimensional zero-one matrix P if no submatrix of A can be transformed to P by changing some ones to zeroes. Let f(n, P, d) denote the maximum number of ones in a d-dimensional n × · · · × n zero-one matrix that avoids P . Fox proved for n sufficiently large that f(n, P, 2) = 2k Θ(1) n for almost all k × k permutation matrices P . We extend this...
