We have investigated shear-induced alignment of a bilayer of spherical diblock copolymer micelles within thin films using molecular dynamics simulations at two different levels of coarse-graining. At the microscopic level, the copolymers are modeled as bead and spring chains with specific interaction potentials which produce strongly segregated spherical micelles. The simulations qualitatively ...

AIM To examine the influence of socioeconomic status on growth pattern in height from age 7 to 23 years. METHODS Prospective cohort study. A total of 10 200 white singleton born children from the 1958 British birth cohort (National Child Development Study) were analysed. RESULTS Differences in height by birth weight persisted throughout the follow up period. However, the mean differences in...

Representing and manipulating sequences in description logics (DLs) h as typically been achieved through the use of new sequence-specific operators or by relying on host-language functions. This paper shows that it is not necessary to add additional features to a DL to handle sequences, and instead describes an approach for dealing with sequences as first-class entities directly within a DL wit...

age and growth of mesopotamian barb, capoeta damascina, were studied in the zayandehrud river, in central iran, from march 2007 to april 2008. among the 689 specimens studied, age groups in males ranged from 1+ to 9+ and that in females ranged from 1+ to 10+. the sex ratio (1m:1.6f) was not significantly different from 1:1 ratio. maximum fork length and weight was 39 cm and 1,115 g for males an...

Spindle cell neoplasms of the upper respiratory tract and oral cavity are unique lesions which pose not only therapeutic problems for the clinician but also difficult interpretive problems for the pathologist. Because of their bizarre microscopic appearance they have frequently been interpreted as sarcomas; however, recent studies suggest that most of these neoplasms are squamous cell carcinoma...

A high level of encephalization is critical to the human adaptive niche and emerged among hominins over the course of the past 2 Myr. Evolving larger brains required important adaptive adjustments, in particular regarding energy allocation and life history. These adaptations included a relatively small brain at birth and a protracted growth of highly dependent offspring within a complex social ...
