Verbal and quantitative genetic models of sexually antagonistic coevolution suggest that coevolutionary arms races should be common. Sexual selection favors exaggeration of male persistence traits that are costly to females, and females, in turn, are selected to resist these traits. The heightened resistance by females is thought to then favor further exaggeration in the male trait, leading to ...

let  be a sequence of arbitrary random variables with  and , for every  and  be an array of real numbers. we will obtain two maximal inequalities for partial sums and weighted sums of random variables and also, we will prove complete convergence for weighted sums , under some conditions on  and sequence .

The author has researched and developed a theory of computation for caricature and has implemented this theory as an interactive computer graphics program. The Caricature Generator program is used to create caricatures by amplifying the differences between the face to be caricatured and a comparison face. This continuous, parallel amplification of facial features on the computer screen simulate...

Recent studies have revealed that some mammals possess adaptations that enable them to produce vocal signals with much lower fundamental frequency (F0) and formant frequency spacing (ΔF) than expected for their size. Although these adaptations are assumed to reflect selection pressures for males to lower frequency components and exaggerate body size in reproductive contexts, this hypothesis has...

The debates continue over the validity of the metabolic syndrome concept. The continuous increment of the obesity pandemic is almost worldwide paralleled by rising rates of metabolic syndrome prevalence. Then, it seems obvious that these debates drove the need for further investigations as well as a deeper cooperation between relevant national and international organizations regarding the issue...

The last 2 years have seen a torrent of information regarding transcatheter aortic valve replacement (TAVR), and it is no exaggeration to say that this compelling technology has revolutionized our approach to treatment of valvular aortic stenosis. High-risk and inoperable patients heretofore relegated to minimally effective medical therapies have been offered a return to activity and, in some c...

concept of divine emanation (as that concept is understood in Neoplatonic philosophy). The insight of apophatic discourse, as well as of contemporary metaphor theory, is that how a person understands these abstract conceptual domains is optional. To view any conceptual mapping as necessary or essential is at best an exaggeration, and at worst an im-
