A dynamic change in the organization of different gene domains transcribed by RNA polymerase I, II, or III occurs during the progression from quiescent [pre-midblastula transition (pre-MBT)] to active (post-MBT) embryos during Xenopus development. In the rDNA, c-myc, and somatic 5S gene domains, a transition from random to specific anchorage to the nuclear matrix occurs when chromatin domains b...

To understand the nature of a cell, one needs to understand the structure of its genome. For this purpose, experimental techniques such as Hi-C detecting chromosomal contacts are used to probe the three-dimensional genomic structure. These experiments yield topological information, consistently showing a hierarchical subdivision of the genome into self-interacting domains across many organisms....

The initial lower and upper power domain constructions P _ and P ^ commute under composition for all cpos. The common result P _ (P ^ X) and P ^ (P _ X) is the free frame over the cpo X.

Stably compact spaces Xs can be described as being derived from compact ordered spaces X by weakening their topology to the open upper sets. In this paper the probabilistic powerdomain of a stably compact space Xs is investigated using the compact ordered space X and classical tools from measure theory and functional analysis. This allows to derive in a unified and elegant way known and new res...

With the explosion of user-generated web2.0 content in the form of blogs, wikis and discussion forums, the Internet has rapidly become a massive dynamic repository of public opinion on an unbounded range of topics. A key enabler of opinion extraction and summarization is sentiment classification: the task of automatically identifying whether a given piece of text expresses positive or negative ...

We present an impr{wed variant of the matrix-triangularization subresultant prs method [1] fi~r the computation of a greatest comnum divi~w of two polynomials A and B (of degrees m and n, respectively) along with their polynomial remainder ~quence. It is impr~wed in the sense that we obtain complete theoretical results, independent {}f Van Vleck's theorem [13] (which is not always tnle [2, 6]),...

The paper is concerned with relation prediction in multi-relational domains using matrix factorization. While most past predictive models focussed on one single relation type between two entity types, in the paper a generalized model is presented that is able to deal with an arbitrary number of relation types and entity types in a domain of interest. The novel multi-relational matrix factorizat...

Let D ⊂ C be a bounded domain, whose boundary B consists of k simple closed continuous curves and H(D) be the algebra of bounded analytic functions on D. We prove the matrix-valued corona theorem for matrices with entries in H(D).

Cross-domain recommender systems represent an emerging research topic as users generally have interactions with items from multiple domains. One goal of a cross-domain recommender system is to improve the quality of recommendations in a target domain by using user preference information from other source domains. We observe that, in many applications, users interact with items of different type...
