Northern South America and South East Asia are today's hotspots of crocodylian diversity with up to six (mainly alligatorid) and four (mainly crocodylid) living species respectively, of which usually no more than two or three occur sympatrically. In contrast, during the late Miocene, 14 species existed in South America. Here we show a diversity peak in sympatric occurrence of at least seven spe...

nodular fasciitis of the breast is a rare benign pathology of soft tissue that is a consequence of fibroblastic hyperplasia within breast. it can mimic breast cancer clinically, radiologically, and histopathologically. a-43 year-old female with a painless mass within upper-lateral quadrant of her left breast complained of rapid and progressive growth during previous few days. no evidence of nip...

Many myths, theories, and speculations exist as to the exact etiology of the diseases that affected famous artistic painters, composers of classical music, and political leaders. Illness can profoundly affect the productivity and creativity of those who are ill (1). Clinical chemistry, had it existed during the lifetimes of various wellknown individuals, might have unraveled the mysteries of th...

importance of sediment storage has been expressed as being higher than that of water in floodwater spreading networks. to determine the contribution of each geological formation in sediment input of gachsaran floodwater spreading station after 12 years of flood spreading, sediment sampling was conducted in 16 points and 0-15 cm depth of the field. using dry sieve analysis, all samples were anal...

Marine transgressions or microbial precipitation: What was the controlling factor of continental margin iron formation deposition? Introduction Iron formations, which can be found around the world today, have great importance as sources of iron and manganese ore, clues about the evolution of life on Earth, and even hints at possible life on Mars (Weber et al., 2006). Precambrian iron formations...

Given a pair of keyframe formations for a group consisting of multiple individuals, we present a spectral-based approach to smoothly transforming a source group formation into a target formation while respecting the clusters of the involved individuals. The proposed method provides an effective means for controlling the macroscopic spatiotemporal arrangement of individuals for applications such...
