Microscopic Theory of Josephson Mesoscopic Constrictions [PDF]
, 1993 We present a microscopic theory for the d.c. Josephson effect in model mesoscopic constrictions. Our method is based on a non-equilibrium Green function formalism which allows for a self-consistent determination of the order parameter profile along the constriction. The various regimes defined by the different length scales (Fermi wavelength $\lambda_F$

On transport in quantum Hall systems with constrictions [PDF]
Europhysics Letters, Vol. 80, 17003 (2007)., 2006 Motivated by recent experimental findings, we study transport in a simple phenomenological model of a quantum Hall edge system with a gate-voltage controlled constriction lowering the local filling factor. The current backscattered from the constriction is seen to arise from the matching of the properties of the edge-current excitations in the ...

Theory of AC Josepson Effect in Superconducting Constrictions [PDF]
, 1997 We have developed a microscopic theory of ac Josephson effect in short ballistic superconducting constrictions with arbitrary electron transparency and in constrictions with diffusive electron transport. The theory is valid for arbitrary miscroscopic structure of the superconducting electrodes of the constriction. As applications of the theory we study

A quantum point contact for neutral atoms [PDF]
Physical Review Letters 83 (19), 3762 (1999), 1999 We show that the conductance of neutral atoms through a tightly confining waveguide constriction is quantized in units of lambda_dB^2/pi, where lambda_dB is the de Broglie wavelength of the incident atoms. Such a constriction forms the atom analogue of an electron quantum point contact and is an example of quantum transport of neutral atoms in an ...

Controlling hysteresis in superconducting constrictions with a resistive shunt [PDF]
Fast Track Communications in Supercond. Sci. Technol. 28 (2015)
072003, 2015 We demonstrate control of the thermal hysteresis in superconducting constrictions by adding a resistive shunt. In order to prevent thermal relaxation oscillations, the shunt resistor is placed in close vicinity of the constriction, making the inductive current-switching time smaller than the thermal equilibration time.

Arthritis &Rheumatology, EarlyView.Objective Cardiovascular disease (CVD) is a leading cause of death in individuals with systemic lupus erythematosus (SLE). We assessed atherosclerotic plaque progression and incident cardiovascular events in patients with SLE over a 10‐year follow‐up.

Effusive-Constrictive Pericarditis
Journal of the American College of Cardiology, 2010 ![Figure][1] A 15-year-old boy developed cough, low-grade fever, and extreme lethargy over 4 weeks that was unresponsive to a short course of macrolide antibiotic. Laboratory workup was notable for a negative Epstein-Barr virus early antigens antibody, monoslide test, and normal ...

Clinical Anatomy, EarlyView.Abstract Although the sternoclavicular joint shares structural similarities with the knee and hip joints as a diarthrodial joint, its biomechanics differ significantly due to its non‐weight‐bearing nature. Nevertheless, it is subject to considerable loading, leading to increased susceptibility to osteoarthritis, a prevalent condition characterized by ...

Indian Journal of Pathology and Microbiology, 2018 Pericardial mesotheliomas are rare tumors which often present with features of constrictive pericarditis. We present clinical, imaging, histological, and immunohistochemical findings of three cases presenting with chronic constrictive pericarditis.
