Sex ratio theory allows unparalleled opportunities for testing how well animal behavior can be predicted by evolutionary theory. For example, Hamilton's theory of local mate competition (LMC) is well understood and can explain variation in sex allocation across numerous species. This allows more specific predictions to be developed and tested. Here we extend LMC theory to a situation that will ...

ABSTRACT We study the local dark matter distribution in two models for Milky Way (MW)-Large Magellanic Cloud (LMC) interaction. The effect of LMC on is dependent evolution MW-LMC system, such that a static model insufficient to accurately velocity solar neighbourhood. An evolved boosts particle velocities by nearly 50 per cent, median value ?750 km s?1. MW particles also experience boost caused...

Some aspects of the theory of Boolean algebras and distributive lattices -in particular, the Stone Representation Theorems and the properties of filters and ideals -are analyzed in a constructive setting.

We have applied the infrared surface brightness (ISB) technique to derive distances to thirteen Cepheid variables in the LMC which span a period range from 3 to 42 days. From the absolute magnitudes of the variables calculated from these distances, we find that the LMC Cepheids define tight period-luminosity relations in the V, I, W, J and K bands which agree exceedingly well with the correspon...

A combination of analytic models and n-body simulations implies that the structural evolution of the Large Magellanic Cloud (LMC) is dominated by its dynamical interaction with the Milky Way. Although expected at some level, the scope of the involvement has significant observational consequences. First, LMC disk orbits are torqued out of the disk plane, thickening the disk and populating a sphe...

BACKGROUND We describe trends in participation by investigators from low- and middle-income countries (LMCs) in publications describing oncology randomized control trials (RCTs) over a decade. METHODS We used Medline to identify RCTs published in English from 1998 to 2008 evaluating treatment in lung, breast, colorectal, stomach and liver cancers. Data on author affiliations, authorship roles...

Context. RR Lyrae stars (RRLS) belong to population II and are generally used as a tracer of the host galaxy halo. Aims. The surface as well as vertical distribution of RRLS in the inner Large Magellanic Cloud (LMC) are studied to understand whether these stars are actually formed in the halo. Methods. RRLS identified by the OGLE III survey are used to estimate their number density distribution...

For high-speed packet transfer in the wireless environment, the shared radio medium is provided to mobile terminals (MT) through the control of MAC layer. Contention and polling technique are known as two fundamental methods that are used in this environment. This paper aims to compare the operation of these two methods if they are enhanced to use in a connected micro-cells system to support fo...

In  cite{GL}, B. Gerla and I. Leuc{s}tean introduced the notion of similarity on MV-algebra. A similarity MV-algebra is an MV-algebra endowed with a binary operation $S$ that verifies certain additional properties. Also, Chirtec{s} in cite{C}, study the notion of similarity on L ukasiewicz-Moisil algebras. In particular, strong similarity L ukasiewicz-Moisil algebras were defined. In this paper...
