Given a complete nonsingular algebraic variety X and a divisor D with normal crossings, we say that X is log homogeneous with boundary D if the logarithmic tangent bundle T X (− log D) is generated by its global sections. We then show that the Albanese morphism α is a fibration with fibers being spherical (in particular, rational) varieties. It follows that all irreducible components of D are n...

Given a complete nonsingular algebraic variety X and a divisor D with normal crossings, we say that X is log homogeneous with boundary D if the logarithmic tangent bundle TX(− log D) is generated by its global sections. Then the Albanese morphism α turns out to be a fibration with fibers being spherical (in particular, rational) varieties. It follows that all irreducible components of D are non...

For a distribution function F on R and a point q ∈ R, the spherical depth SphD(q;F ) is defined to be the probability that a point q is contained inside a random closed hyper-ball obtained from a pair of points from F . The spherical depth SphD(q;S) is also defined for an arbitrary data set S ⊆ R and q ∈ R. This definition is based on counting all of the closed hyper-balls, obtained from pairs ...

A low resistivity annulus appearing near the well due to reservoir fluid displacement by mud filtrate is a reliable indicator of movable oil presence in reservoir. In practical cases estimation parameters possible based on high-frequency induction logging data analysis. When interpreting other methods its influence signals usually not taken into account. The paper discusses results 5IK and VIKI...

A technique to improve contacts of solar cells laser enhanced contact optimization (LECO) has been studied in terms micro scale formation at industrial PERC cells. High-resolution diagnostics by focused ion beam techniques and scanning electron transmission microscopy indicate the LECO-induced microscopic buried interface between screen-printed silver finger silicon wafer. large quantity these ...

MOTIVATION: In lung EIT, the quantity of interest is the change in regional air volume in the lungs. However, the actual quantity reconstructed is change in a bulk electrical property, usually conductivity, which is not always easy to interpret. In this study, we investigate how the choice of the reconstructed physical quantity affects the properties of the sensitivity matrix and images obtaine...
