Calcific pericarditis strangling the heart, an answer to unexplained heart failurediagnostic modalities

open access: yesJournal of the Pakistan Medical Association
Pericardial calcification is often found incidentally from imaging studies and may be a clue to constrictive pericarditis. Constrictive pericarditis often mimics other causes of heart failure, pulmonary, or liver disease, making it hard to diagnose ...

Constrictive Pericarditis Presenting as Isolated Ascites

open access: yesRadiology Case Reports, 2022
Constrictive pericarditis is a rare cause of right-sided heart failure secondary to a stiff, non-compliant pericardium. Clinical presentation can vary considerably and requires a high suspicion for diagnosis. A 31-year-old male presented to the emergency

Constrictive pericarditis following Coronary Artery Bypass Grafting

open access: yesIndian Heart Journal, 2013
Constrictive pericarditis following Coronary Artery Bypass Surgery is an uncommon disorder. We report a patient who developed constrictive pericarditis after Coronary Artery Bypass Grafting.

A Complicated Case of Transient Constrictive Pericarditis Secondary to Rivaroxaban-Associated Hemopericardium

open access: yesJACC: Case Reports, 2020
A 72-year-old man on rivaroxaban developed effusive constrictive pericarditis secondary to hemopericardium. His condition improved with anti-inflammatory therapy supporting a diagnosis of transient constrictive pericarditis.

Microscopic Theory of Josephson Mesoscopic Constrictions [PDF]

open access: yes, 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]

open access: yesEurophysics 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]

open access: yes, 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]

open access: yesPhysical 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]

open access: yesFast 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.

Morphology of the sternoclavicular joint and its microanatomical changes in response to osteoarthritic degeneration

open access: yesClinical 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 ...
