Time-Dependent Invariants and Green's Functions in the Probability Representation of Quantum Mechanics [PDF]

open access: yes, 1998
In the probability representation of quantum mechanics, quantum states are represented by a classical probability distribution, the marginal distribution function (MDF), whose time dependence is governed by a classical evolution equation.

Design and implementation of a small AODF

open access: yesThe Journal of Engineering, 2019
Cross-connection is the only point in the communications field that has not been automated. With the many fibre networks that have been built, there is strong demand from operators for an automatic optical distribution frame (AODF) to reduce operational ...

Photometry and the Metallicity Distribution of the Outer Halo of M31 [PDF]

open access: yes, 2001
We have conducted a wide-field CCD-mosaic study of the resolved red-giant branch (RGB) stars of M31, in a field located 20 kpc from the nucleus along the SE minor axis. In our (I, V-I) color-magnitude diagram, RGB stars in the top three magnitudes of the

Clinical relevance of double‐arm blood pressure measurement and prevalence of clinically important inter‐arm blood pressure differences in Indian Primary Care

open access: yesThe Journal of Clinical Hypertension, Accepted Article., 2022
Abstract Hypertension guidelines recommend measuring blood pressure (BP) in both arms at least once. However, this is seldom done due to uncertainties regarding measurement procedure and the implications of finding a clinically important inter‐arm BP difference (IAD).

Metallicity Distribution Functions of Four Local Group dwarf galaxies [PDF]

open access: yes, 2015
We present stellar metallicities in Leo I, Leo II, IC 1613, and Phoenix dwarf galaxies derived from medium (F390M) and broad (F555W, F814W) band photometry using the Wide Field Camera 3 (WFC3) instrument aboard the Hubble Space Telescope.
