Directional epistasis describes a situation in which epistasis consistently increases or decreases the effect of allele substitutions, thereby affecting the amount of additive genetic variance available for selection in a given direction. This study applies a recent parameterization of directionality of epistasis to empirical data. Data stems from a QTL mapping study on an intercross between in...

Additive Cost Register Automata (ACRA) map strings to integers using a finite set of registers that are updated using assignments of the form “x := y+ c” at every step. The corresponding class of additive regular functions has multiple equivalent characterizations, appealing closure properties, and a decidable equivalence problem. In this paper, we solve two decision problems for this model. Fi...

Social networks have become more and more popular in recent years. This popularity creates a need for personalization services to recommend tweets, posts (information) and celebrities organizations (information sources) to users according to their potential interest. Tencent Weibo (microblog) data in KDD Cup 2012 brings one such challenge to the researchers in the knowledge discovery and data m...

We exhibit the analog of entropy map for multivariate Gaussian distributions on local fields. As in real case, image this lies supermodular cone and it determines distribution valuation vector. In general, can be defined non-archimedian valued fields whose group is an additive subgroup line, remains supermodular. also explicitly compute dimension 3.

In the last few years, the use of i-vectors along with a generative back-end has become the new standard in speaker recognition. An i-vector is a compact representation of a speaker utterance extracted from a low dimensional total variability subspace. Although current speaker recognition systems achieve very good results in clean training and test conditions, the performance degrades considera...

We show how to make the additive Chow groups of Bloch-Esnault, Rülling and Park into a graded module for Bloch's higher Chow groups, in the case of a smooth projective variety over a field. This yields a a projective bundle formula as well as a blow-up formula for the additive Chow groups of a smooth projective variety. In case the base-field admits resolution of singularieties, these propertie...

basal stem rot caused by sclerotinia sclerotiorum (lib.) de bary is one of the most important diseases of sunflower. quantitative trait loci (qtl) implicated in partial resistance to two isolates of s. sclerotiorum (ssu107 and sskh41) were investigated using f9 recombinant inbred lines (rils) from the cross between sunflower parental lines pac2 and rha266. experiments were conducted in complete...

The multistability exhibited by first-order delay-differential equations ~DDE’s! at large delay-to-response ratios R is useful for the design of dynamical memory devices. This paper first characterizes multistability in the Mackey-Glass DDE at large R . The extended control of its unstable periodic orbits ~UPO’s!, based on additional feedback terms evaluated at many times in the past, is then p...

In this paper we evaluate the performance of list sequence (LS) maximum a posteriori probability (MAP) decoding on the additive white Gaussian noise (AWGN) channel and the fully interleaved flat Rayleigh fading channel. In particular, we focus on the frame error rate (FER) of LS-MAP decoding with genie-assisted error detection. It is demonstrated that LS-MAP decoding yields significant performa...
