This paper presents ALBA-R, a protocol for converge casting in wireless sensor networks. ALBA-R features the crosslayer integration of geographic routing with contention-based MAC for relay selection and load balancing (ALBA), as well as a mechanism to detect and route around connectivity holes (Rainbow). ALBA and Rainbow (ALBA-R) together solve the problem of routing around a dead end without ...

1. Although colour polymorphisms are a widespread and conspicuous component of extant biodiversity, the selective pressures that act to maintain multiple morphs within populations remain poorly understood in most cases. In particular, the role that visual system limitations may play in maintaining multiple colour morphs is not well explored. 2. We used a female-limited colour polymorphism commo...

We introduce a new fragment of Linear temporal logic (LTL) called LIO and a new class of Büchi automata (BA) called Almost linear Büchi automata (ALBA). We provide effective translations between LIO and ALBA showing that the two formalisms are expressively equivalent. While standard translations of LTL into BA use some intermediate formalisms, the presented translation of LIO into ALBA is direc...

The Salix alba L. (white willow)—Salix fragilis L. (crack willow) complex includes closely related polyploid species, mainly tetraploid (2n = 4x = 76), which are dioecious and hence obligate allogamous. Because little is known about the genome constitution and chromosome behavior of these pure willow trees, genetic analysis of their naturally occurring interspecific polyploid hybrids is still v...

Oxidative stress and Ultraviolet (UV) irradiation-induced skin damage, is involved in numerous diseases. Eclipta alba which belongs to Asteraceae family is used traditionally in Ayurvedic system of medicine in India for the treatment of liver diseases. Our study shows that water extract of E. alba has a potent effect in scavenging 1, 1-diphenyl-2-picrylhydrazyl (DPPH), chelating ferrous ion, an...
