Hox genes encode homeodomain transcription factors that control morphogenesis and have established functions in development and evolution. Hox proteins have remained enigmatic with regard to the molecular mechanisms that endow them with specific and diverse functions, and to the cellular functions that they control. Here, we review recent examples of Hox-controlled cellular functions that highl...

the photoanthropometric method was used to study the facial features in 136 iranian children with down syndrome, aged 4 to 14 years. nineteen parameters were investigated and compared to an age related control group of 100 normal iranian children. the obtained measurements were related to reference values in the same faces. the normal range was defined by age related index values between the 20...

The coexistence of superconductivity and ferromagnetism in 1212-RuSr GdCu O is unique among high-T materials. Samples of 2 2 8 c Ru M Sr GdCu O , with M5Ti, V and Nb; and 0#x#1, were prepared to elucidate the role of the RuO planes in this interesting 1 2 x x 2 2 8 2 layered 1212 cuprate. The solubility ranges of M5Ti and V are limited to x,0.15 whereas that of Nb extends to full substitution. ...

Russian roulette and splitting are widely used techniques to increase the efficiency of Monte Carlo estimators. But, despite their popularity, there is little work on how best apply them. Most existing approaches rely simple heuristics based on, e.g., surface albedo roughness. Their often hinges user-controlled parameters. We instead iteratively learn optimal factors during rendering, using a l...

The structural and electronic properties of sheets and nanotubes of boron are investigated using density functional theory. The calculations predict the stability of a novel reconstructed {1221} sheet over the idealized triangular {1212} sheet. Nanotubes formed by wrapping the half-metallic {1221} sheet show a curvature-induced transition in their electronic properties. Analysis of the charge d...

The Ormia ochracea is able to locate a cricket's mating call despite the small distance between its ears compared with the wavelength. This phenomenon has been explained by the mechanical coupling between the ears. In this paper, it is first shown that the coupling enhances the differences in times of arrival and frequency responses of the ears to the incoming source signals. Then, the accuracy...

Introduction Observing the obliquity of stapes by closely scrutinizing the HRCT temporal bone in otosclerosis revealed a reliable and consistent finding. This finding can add to the existing radiological criteria in diagnosis of otosclerosis. Objective The objective of this study is to establish the obliquity of stapes in otosclerosis by radiological measurements using HRCT temporal bone by com...
