Sexual selection is an intense evolutionary force, which operates through competition for the access to breeding resources. There are many cases where male copulatory success is highly asymmetric, and few males are able to sire most females. Two main hypotheses were proposed to explain this asymmetry: "female choice" and "male dominance". The literature reports contrasting results. This variabi...

Methods to calculate bias-adjusted estimates for meta-analyses are becoming more popular. The objective of this paper is to use the structural approach to bias and causal diagrams to show that (i) the current use of the bias-adjusted estimating tools may sometimes introduce bias rather than reduce it and (ii) the Cochrane collaboration risk of bias tool, which was designed for randomized studie...

1. Surface Networks Surface Network also called Pfaltz’s Graph is a graph-based model of terrains, proposed by Pfaltz (1976). In Surface Network, the nodes are the three most important topographic point features, namely pits, peaks, and passes. The edges of the graph are the ridges and channels. The ridges correspond to the paths between passes to the peaks and the channels correspond to the pa...

--Ignitor has been the first experiment proposed and designed to reach ignition conditions in magnetically confined plasmas.It is a compact ,high field machine based on the physics developed primarily by the Alcator series of experiments. Each refinement of IGNITOR has drawn from a common set of "tools": Bitter plate copper magnets; bucking/wedging interactions of the CS and TF coils; and passi...

Categories are not invariant. This paper attempts to explore the dynamic nature of semantic category, in particular, that of fashion language, based on the cognitive theory of Dawkins’ memetics, a new theory of cultural evolution. Semantic attributes of linguistic memes decrease or proliferate in replication and spreading, which involves a dynamic development of semantic category. More specific...

construction of railway embankments on loose beds without using any methods of soil improvement (e.g. stone columns in silt and clay beds, deep soil mixing method, jet grouting and also using micropiles individually or in groups form) leads to  reduction of embankment slope gradient, which significantly increases the volume of soil operation. generally, micropile as a reinforcing element with t...

We introduce Dynamic SOS as a framework for describing semantics of programming languages that include dynamic software upgrades. Dynamic SOS (DSOS) is built on top of the Modular SOS of P. Mosses, with an underlying category theory formalization. The idea of Dynamic SOS is to bring out the essential differences between dynamic upgrade constructs and program execution constructs. The important ...

the spectroscopic properties of the 2,2,6,6-tetramethyl-piperidine-1-oxyl (tempo) radicalderivatives of the fullerene (c60) were theoretically investigated. the ground state optimizedstructures of the radical adducts of the fullerene were calculated by using dft (b3lyp) with 6-31g(d) level. it was concluded that a 6-6 ring junction of c60 moiety generally covalently links to thepiperidine ring ...
