Dwarf galaxies (DGs) are more numerous than large galaxies. Most dwarfs in clusters are dEs, but in the field they belong mostly to late types. The importance of late-type DGs in the context of the intergalactic medium (IGM) lies in the fact that (at least some) are probably " young " galaxies forming stars for the first time. Many DGs have significant amounts of interstellar gas, they may form...

Pore network modeling uses a network of pores connected by throats to model the void space of a porous medium and tries to predict its various characteristics during multiphase flow of various fluids. In most cases, a non-realistic regular lattice of pores is used to model the characteristics of a porous medium. Although some methodologies for extracting geologically realistic irregular net...

Volvox barberi is a multicellular green alga forming spherical colonies of 10,000-50,000 differentiated somatic and germ cells. We observed that in culture, these actively self-organized just few minutes into flocks contained as many 100 moving rotating collectively for hours. The formed two-dimensional, irregular, active crystals, is, geometric lattices within which individual rotated separate...

〈Summary〉 3D structure of proteins deeply relates to their functionality. It is wellknown that functions of proteins strongly appear in the bumpy parts of the molecular surfaces, and therefore geometric analysis of protein molecular surfaces is important. We propose a technique to extract geometric features of protein molecular surfaces, and a visual interface to effectively visualize the extra...

In geometric modeling and processing, computer graphics, smooth surfaces are approximated by discrete triangular meshes reconstructed from sample points on the surface. A fundamental problem is to design rigorous algorithms to guarantee the geometric approximation accuracy by controlling the sampling density. This theoretic work gives explicit formula to the bounds of Hausdorff distance, normal...

PATIENT(S) A total of 186 couples who intended to discontinue contraception to become pregnant were followed until pregnancy or for six menstrual cycles. INTERVENTION(S) None.
