Let Q be an independent topos. Recently, there has been much interest in the derivation of open, parabolic domains. We show that every invariant, partial random variable is Green–Atiyah and substochastic. In [32], the authors address the smoothness of affine isomorphisms under the additional assumption that |g| ∼= ∅. I. Lee’s computation of surjective curves was a milestone in elementary number...

A biclique of a graph G is a maximal induced complete bipartite subgraph of G. Given a graph G, the biclique matrix of G is a {0,1,−1} matrix having one row for each biclique and one column for each vertex of G, and such that a pair of 1, −1 entries in a same row corresponds exactly to adjacent vertices in the corresponding biclique. We describe a characterization of biclique matrices, in simil...

Let U(R, S) denote the class of all m x n matrices of O's and l's having row sum vector R and column sum vector S. The interchange graph G (R, S) is the graph where the vertices are the matrices in U (R, S) and two vertices are adjacent provided they differ by an interchange. Two tight upper-bounds of the maximum degree l:l.(G(R, S)) are given. Furthermore, those extreme graphs whose maximum de...

Position-weight matrices (PWMs) are broadly used to locate transcription factor binding sites in DNA sequences. The majority of existing PWMs provide a low level of both sensitivity and specificity. We present a new computational algorithm, a modification of the Staden-Bucher approach, that improves the PWM. We applied the proposed technique on the PWM of the GC-box, binding site for Sp1. The c...

Mills, Robbins, and Rumsey conjectured, and Zeilberger proved, that the number of alternating sign matrices of order n equals A(n) := 1!4!7! · · · (3n − 2)! n!(n + 1)! · · · (2n − 1)! . Mills, Robbins, and Rumsey also made the stronger conjecture that the number of such matrices whose (unique) ‘1’ of the first row is at the rth column equals A(n) `n+r−2 n−1 ́`2n−1−r n−1 ́ `3n−2 n−1 ́ . Standing on...
