During the last decade, an optical vortex (OV) has widely drawn attention since it refers to a unique fact that the spatial phase of an electromagnetic wave changes linearly, at its cross-section, with the azimuthal angle φ around the center point, named singularity point where there is no field distribution [1]. This special property of phase profile is described by a factor of exp(ilφ), where...

Manipulation of surface plasmon polaritons (SPP) by phase modulation of incident light beams is proposed with analytical and numerical verifications when an optical vortex (OV) beam is employed as an example. Fundamental functionalities of a plasmonic chip such as in-plane focusing, coupling and multiplexing of SPP by sequentially varying the topological charge of OV beam are demonstrated. Comp...

Background: Disrespect and abuse during facility-based childbirth is a global problem with differing driving factors in different contexts. Obstetric Violence (OV) refers to professional deficiencies maternity care. The objective of this study was assess knowledge attitudes towards OV cohort members the obstetric healthcare team at tertiary care, teaching hospital Western India (Mumbai).Methods...

Limiting absorption principle is justified for second-order selfadjoint elliptic operators in two-dimensional spaces.

A complete classification of binary doubly even self-dual codes of length 40 is given. As a consequence, a classification of binary extremal self-dual codes of length 38 is also given. ∗This work was supported by JST PRESTO program.

We investigate certain properties of the Wheeler-DeWitt metric (for constant lapse) in canonical General Realtivity associated with its non-definite nature.

Consider X 1 , X 2 ,. .. , X n that are independent and identically N(µ, σ 2) distributed. Suppose that we have uncertain prior information that µ = 0. We answer the question: to what extent can a frequentist 1−α confidence interval for µ utilize this prior information?

We review in this talk some aspects of the exciting field of hyperon polarization phenomena in high energy reactions, over the last twenty years or so. On the experimental side, a large amount of significant polarization data for hyperon and antihyperon inclusive production, has been accumulated in a rather broad energy range. Many theoretical attempts to explain that have been proposed and we ...
