Bound - states for truncated Coulomb potentials

open access: yes, 2000
The pseudoperturbative shifted - $l$ expansion technique PSLET is generalized for states with arbitrary number of nodal zeros. Bound- states energy eigenvalues for two truncated coulombic potentials are calculated using PSLET.

Perceptual discrimination of complex objects: Apolipoprotein E e4 gene‐dose effects in mid‐life

open access: yesAlzheimer's &Dementia, Volume 21, Issue 6, June 2025.
Abstract INTRODUCTION Complex perceptual discrimination is supported by tau‐vulnerable regions of the medial temporal lobe (MTL); notably the perirhinal cortex. This research tests whether there is a gene‐dose effect of apolipoprotein E (APOE) e4 on perceptual discrimination in mid‐life.

Petroleum – Strategic Resource for World Economy

open access: yesStudia Universitatis Vasile Goldis Arad, Seria Stiinte Economice, 2018
Petroleum is the most important resource for global energy production, far exceeding the role of coal and natural gas, the role of river energy and wind energy, and also the role of nuclear fuel.

Agricultural Financing and Unemployment Rate in Nigeria: A Cointegration Approach

open access: yesActa Universitatis Sapientiae: Economics and Business, 2020
In Nigeria, the level of agricultural productivity and farmers’ income have been affected by inadequate financing, which invariably discourages job creation and increases unemployment rate.

The Role of Lithium Ions on the Solubility of K4E4 in Ethylenediamine and the Oxidation of the Zintl Anions [E4]4− (E = Ge, Sn, Pb) as well as [Ge9]4−

open access: yesChemistry – A European Journal, Volume 31, Issue 26, May 8, 2025.
The solubility of K4Ge4, K4Sn4, and K4Pb4 phases and oxidation of comprised four‐atom clusters in ethylenediamine (en) is induced by the addition of LiCl. The 119Sn NMR spectra of [Sn9]4− with Li+ and K+ counterions indicate a cation‐dependent change in both the chemical shift and coupling constant, strongly suggesting K+/[Sn9]4− ion pairing, which is ...

Miyashita Action in Strongly Groupoid Graded Rings [PDF]

open access: yes, 2010
We determine the commutant of homogeneous subrings in strongly groupoid graded rings in terms of an action on the ring induced by the grading. Thereby we generalize a classical result of Miyashita from the group graded case to the groupoid graded ...

On String S-matrix, Bound States and TBA

open access: yes, 2007
The study of finite J effects for the light-cone AdS superstring by means of the Thermodynamic Bethe Ansatz requires an understanding of a companion 2d theory which we call the mirror model.

Joint Wire Cutting with Non‐Maximally Entangled States

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 5, May 2025.
Wire cutting decomposes large quantum circuits into smaller subcircuits by severing connecting wires, enabling execution on multiple distributed devices. This study employs non‐maximally entangled (NME) states in joint wire cuts to reduce their overhead.

Modeling the 2010 blast wave of the symbiotic-like nova V407 Cygni

open access: yes, 2011
(Abridged) The symbiotic-like binary Mira and nova V407 Cyg was observed in outburst on March 2010 and monitored in several wavelength bands. Here we report on multi-dimensional hydrodynamic simulations describing the 2010 outburst of V407 Cyg, exploring
