We study the numerical solution of scalar time-harmonic wave equations on unbounded domains which can be split into a bounded interior domain primary interest and an exterior with separab...

The evolutionary implications of transposable element (TE) influences on gene regulation are explored here. An historical perspective is presented to underscore the importance of TE influences on gene regulation with respect to both the discovery of TEs and the early conceptualization of their potential impact on host genome evolution. Evidence that points to a role for TEs in host gene regulat...

Transposable elements (TEs) are the major component of most plant genomes, and characterizing their population dynamics is key to understanding plant genome complexity. Yet there have been few studies of TE population genetics in plant systems. To study the roles of selection, transposition, and demography in shaping TE population diversity, we generated a polymorphism dataset for six TE famili...

Transposable elements (TEs) are ubiquitous in eukaryotic genomes. Barbara McClintock's famous notion of TEs acting as controlling elements modifying the genetic response of an organism upon exposure to stressful environments has since been solidly supported in a series of model organisms. This requires the TE activity response to possess an element of specificity and be targeted toward certain ...

Transposable elements (TEs) are a major source of genetic variability in genomes, creating genetic novelty and driving genome evolution. Analysis of sequenced genomes has revealed considerable diversity in TE families, copy number, and localization between different, closely related species. For instance, although the twin species Drosophila melanogaster and D. simulans share the same TE famili...

Transposable elements (TEs) are among the most abundant components of many eukaryotic genomes. Efforts to explain TE abundance, as well as TE diversity among genomes, have led some researchers to draw an analogy between genomic and ecological processes. Adopting this perspective, we conducted an analysis of the cow (Bos taurus) genome using techniques developed by community ecologists to determ...

the body of residential complexes is affected by social interactions between residents over time. of the most important places for social communications are bazaars as the backbone of iranian cities. ancient bazaar of babol in north of iran contains natural features which makes a special sense of place. this essay tries to answer to how concept of sense of place is presented and what are factor...
