Horizontal Partitioning has been largely adopted by the database community, where it took a significant part in the physical design process. Actually, it is supported by most commercial database systems (DBMS), where a native Data Definition Language for decomposing tables/materialized views using various modes is proposed. In traditional databases, horizontal partitioning has been largely stud...

In theory, plasmids can only be maintained in a population when the rate of horizontal gene transfer is larger than the combined effect of segregational loss and the decrease of fitness associated with plasmid carriage. Recent advances in genome sequencing have shown, however, that a large fraction of plasmids do not carry the genes necessary for conjugation or mobilization. So, how are so-call...

Green-tree retention has been promoted as an alternative management tool to create structurally complex forests that would resemble late-successional forests faster than single-aged stands planted after clearcuts. To evaluate if and how overstory residual trees were associated with a higher structural complexity, nine pairs of naturally regenerated stands, initiated between 55 and 110 yr ago wi...

Summary In this study, the seismic performance of hexagrid structures which are composed of horizontal and vertical hexagrid by using a transitional story, has been investigated. To this end, 10 models of 50-story hexagrid structures were designed. 9 models with horizontal hexagrid cells which transited to vertical cells using a transitional story, and a model of completely horizontal hexagrid ...

Intelligence studies missed social science’s “complexity turn” more than twenty years ago. The aim of this article is to examine military intelligence from a complexity science perspective and discuss related concepts such as sensemaking reflexivity. For this, theory, doctrine, practice are studied. Complexity insights sciences used review mental models current thinking in intelligence. Rather ...

due to the particular importance of projects in human life and in organizations, proper project management has been always regarded highly by researchers and practitioners. recent advances in technology and fundamental changes in most scientific areas have affected projects and made their nature and environmental circumstances much more complex than in the past. fortunately, in recent years, ma...

Horizontal gene transfer has been increasingly documented between eukaryotes, but a new study suggests a much larger role for horizontal gene transfer in physiological adaption through the transfer of photosynthetic pathway genes.

To some extent, the genetic theory of adaptive evolution in bacteria is a simple extension of that developed for sexually reproducing eukaryotes. In other, fundamental ways, the process of adaptive evolution in bacteria is quantitatively and qualitatively different from that of organisms for which recombination is an integral part of the reproduction process. In this speculative and opinionated...
