Homozygous brachymorphic (bm/bm) mice are characterized by disproportionately short stature. Newborn bm/bm epiphyseal cartilages are shorter than normal although the cells in the different zones of growth are relatively well organized. The extracellular matrix reacts poorly with stains specific for sulfated glycosaminoglycans. The ultrastructural appearance of the cartilage matrix indicates nor...

Sox5 and Sox6 encode Sry-related transcription factors that redundantly promote early chondroblast differentiation. Using mouse embryos with three or four null alleles of Sox5 and Sox6, we show that they are also essential and redundant in major steps of growth plate chondrocyte differentiation. Sox5 and Sox6 promote the development of a highly proliferating pool of chondroblasts between the ep...

This paper presents a novel hybrid method for extracting license plates and recognizing characters from low-quality videos using morphological operations and Adaboost algorithm. First of all, the hybrid method uses the Adaboost algorithm for training a detector to detect license plates. This algorithm works well to detect license plates having lower intensities but fails to detect license plate...

We describe laboratory-grown snow crystals that exhibit a triangular, plate-like morphology, and we show that the occurrence of these crystals is much more frequent than one would expect from random growth perturbations of the more-typical hexagonal forms. We then describe an aerodynamic model that explains the formation of these crystals. A single growth perturbation on one facet of a hexagona...

The pour plate method of counting bacteria is more precise than the streak plate method, but, on the average, it will give a lower count.
