Persistent currents in quantum phase slip rings

open access: yes, 2013
We investigate the effect of interacting quantum phase slips on persistent current and its fluctuations in ultrathin superconducting nanowires and nanorings pierced by the external magnetic flux.

Spatial Dynamics of Harbour Porpoise Phocoena phocoena Relative to Local Hydrodynamics and Environmental Conditions

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
This study uses a multidisciplinary approach to model the habitat use and site occurrence of harbour porpoises, identifying areas where they were seen spending most time in the Skerries and Causeway Special Area of Conservation. The results show that porpoises are most concentrated within 500 m of the shoreline, particularly near headlands with coarse ...

Suppression of superconductivity at nematic critical point in underdoped cuprates

open access: yes, 2012
A nematic quantum critical point is anticipated to exist in the superconducting dome of some high-temperature superconductors. The nematic order competes with the superconducting order and hence reduces the superconducting condensate at $T = 0$. Moreover,

Modelling the Habitat Distribution of the Endemic Azooxanthellate Coral Madracis interjecta From the Mesophotic to the Deep Red Sea

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
The azooxanthellate Scleractinian Madracis interjecta is often observed in mesophotic ecosystems and has been reported to form sediment‐binding bioherms, yet the conditions required for these formations are not understood. We present a habitat suitability model to identify potential habitats in the northern Red Sea and Gulf of Aqaba for this species ...

Evolution of Superconductivity in Electron-Doped Cuprates: Magneto-Raman Spectroscopy

open access: yes, 2005
The electron-doped cuprates Pr_{2-x}Ce_xCuO_4 and Nd_{2-x}Ce_xCuO_4 have been studied by electronic Raman spectroscopy across the entire region of the superconducting (SC) phase diagram.

Process Intensification for Recombinant Marburg Virus Glycoprotein Production Using Drosophila S2 Cells

open access: yesEngineering in Life Sciences, Volume 25, Issue 5, May 2025.
ABSTRACT Marburg marburgvirus (MARV) is a highly virulent human pathogen with limited therapeutic options. Recombinant MARV glycoprotein (GP) produced in Drosophila Schneider 2 (S2) cells has been extensively investigated as potential vaccine antigen with promising efficacy demonstrated in nonhuman primate models.

PAL-Hom method for QP and an application to LP [PDF]

open access: yesComputational Optimization and Applications, 2019
In this paper, a proximal augmented Lagrangian homotopy (PAL-Hom) method for solving convex quadratic programming problems is proposed. This method takes the proximal augmented Lagrangian method as the outer iteration. To solve the proximal augmented Lagrangian subproblems, a homotopy method is presented as the inner iteration.

Severe Impact of Omeprazole Timing on pH‐Sensitive Dasatinib Absorption: Unveiling Substantial Drug–Drug Interaction

open access: yesThe Journal of Clinical Pharmacology, Volume 65, Issue 5, Page 588-597, May 2025.
Abstract The absorption and bioavailability of most tyrosine kinase inhibitors are affected by gastrointestinal pH as they are weak basic lipophilic drugs. Hence, concomitant use of acid reducing agents (ARAs) is frequently restricted. Particularly comedication of crystalline dasatinib (Sprycel) and proton‐pump inhibitors (PPIs) should be avoided. Drug–

Coulomb Blockade due to Quantum Phase-Slips Illustrated with Devices

open access: yes, 2011
In order to illustrate the emergence of Coulomb blockade from coherent quantum phase-slip processes in thin superconducting wires, we propose and theoretically investigate two elementary setups, or "devices".

A kind of QP-free feasible method

open access: yesJournal of Computational and Applied Mathematics, 2009
AbstractThis paper is concerned with a kind of QP-free feasible algorithm which solves an inequality constrained nonlinear optimization problem. Under some weaker conditions than those in [H. Qi, L. Qi, A New QP-free, globally convergent, locally superlinear convergent algorithm for inequality constrained optimization, SIAM J. Optim. 11 (2000) 113–132],
