A 33–year-old woman was visited at the dermatological clinic of Loghman-e-Hakim Hospital with multiple hypopigmented patches on her right arm, buttocks and flanks. Her lesions developed over the past year with no regression. Lesions were resistant to multiple antifungal therapies. Clinical examination revealed multiple circular or oval patches on the right arm, flank and sacral area. There was ...

The brain processes objects through a series of regions along the ventral visual pathway, but the circuitry subserving the analysis of specific complex forms remains unknown. One complex form category, faces, selectively activates six patches of cortex in the macaque ventral pathway. To identify the connectivity of these face patches, we used electrical microstimulation combined with simultaneo...

We propose a model for the presence/absence of a population in a collection of habitat patches. This model assumes that colonisation and extinction of the patches occur as distinct phases. Importantly, the local extinction probabilities are allowed to vary between patches. This permits an investigation of the effect of habitat degradation on the persistence of the population. The limiting behav...

ome transcription factors take a chaperone to the nuclear dance. On page 469, Williams et al. show that STAT5A gets this escort from the ERBB4 receptor tyrosine kinase. ERBB4 becomes an escort upon activation by growth factors such as heregulin (HRG). The activated receptor is known to recruit and phos-phorylate STAT5A and get cleaved, thus releasing ERBB4's intracellular domain (4ICD). William...

B-patches are the analogue to B-spline segments for triangular surfaces and are the main building block in the new multivariate B-spline surfaces recently developed in [8). This paper discusses algorithms for B-patches and presents algorithms for computing the polar form, for evaluation, for differentiation, for computing continuous joints, and for knot insertion .

landscape metrics quantifies structural features of the landscape. one of the advantages of these metrics is a possibility to use them in fast cumulative assessment of the development activities in the environment. in this paper, the cumulative effects of road network expansion on the tree cover of gorgan, kordkuy, aliabad townships in golestan province were investigated. to prepare the require...
