Genetic linkage maps have the potential to facilitate the genetic dissection of complex traits and comparative analyses of genome structure, as well as molecular breeding efforts in species of agronomic importance. Until recently, the majority of such maps was based on relatively low-throughput marker technologies, which limited marker density across the genome. The availability of high-through...

interaction of two complementary growth-factor dependent mutants, i.e., Tzp lemen ta ry auxotrophs, of Streptomyces coeticolor to form grovvth-factor independent progeny, i.e., prototrophs, was interpreted as gene recombination by SERMO~TI and SPADA-SERMONTI (1955) and by BRAENDLE and SZ+BALSKI (1959yi but as heterokaryosis by BRADLEY (1957). The former workers concluded that gene recombination...

Birth (n = 308), weaning (n = 291), feedlot and carcass (n = 142), and yearling heifer traits (n = 139) were evaluated in F1 calves sired by Brahman (BR), Boran (BO), and Tuli (TU) bulls and born to multiparous Hereford and Angus cows. Calves sired by BR were heaviest (P < .05) at birth and largest (P < .05) for cannon bone length. Tuli crosses were smaller (P < .05) for birth weight and cannon...

Onsager crosses are hard nonconvex bodies formed by rigidly connecting three elongated rods, equally thick but not necessarily equally long, to form perpendicular crosses. We study the phase behavior of systems of such particles, focusing on their ability to form spatially homogeneous orientationally ordered phases with a symmetry lower than that of the standard uniaxial nematic. We treat these...

Although Event Stream Processing (ESP) systems exit for already more than a decade, we recently witness a true renaisance for ESP systems that have adopted the popular MapReduce paradigm. In this white paper, we advocate for the StreamMapReduce approach as it allows a (i) quick and easy transition of legacy MapReduce-based applications to ESP, (ii) simplifies the implementation of fault toleran...

JANUARY/FEBRUARY 2016 | IEEE SOFTWARE 29 LIKE MANY PEOPLE, we’ve been following closely the rapidly unfolding story on the “defeat” software at Germany’s giant automotive company, VW. This, we believe, adds a new dimension to our original questions, “Software: What’s in it and what’s it in?”1—particularly, “What’s hidden in it, and how many people knew?” It would appear that aside from the norm...
