Self-consistent Hartree theory of the role of electron-electron interactions in the electronic structure and conductance quantization of graphene nanoconstrictions [PDF]

arXiv, 2012
We present self-consistent calculations of electron transport in graphene nanoconstrictions within the Hartree approximation. We consider suspended armchair ribbons with V-shaped constrictions having perfect armchair or zigzag edges as well as mesoscopically smooth but atomically stepped constrictions with cosine profiles. Our calculations are based on

Andreev States in long shallow SNS constrictions [PDF]

, 2001
We study Andreev bound states in a long shallow normal constriction, which is open to a superconductor at both ends. The interesting features of such setup include the absence of electron-hole symmetry and the interference of electron waves along the constriction.

Resolution of a caudal mediastinal paraoesophageal empyema in a cat without surgical intervention

Veterinary Record Case Reports, EarlyView.
Abstract A 5‐year‐old, male, neutered European shorthair cat presented with hyporexia and acute respiratory distress of 2 weeks. Thoracic radiographs showed pleural effusion and two round masses in the dorsal thoracic cavity. Computed tomography revealed a caudal mediastinal paraoesophageal empyema, and there were no signs of a foreign body.

Cognitive Machine-Learning Algorithm for Cardiac Imaging: A Pilot Study for Differentiating Constrictive Pericarditis From Restrictive Cardiomyopathy.

Circulation Cardiovascular Imaging, 2016
BACKGROUND Associating a patient's profile with the memories of prototypical patients built through previous repeat clinical experience is a key process in clinical judgment.

Radiological Insights Into the Pericardium: A Comprehensive Review

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT The pericardium is not simply a two‐layered membrane surrounding the heart and great vessels. Pericardial effusion is the most common manifestation of various pathological conditions involving the pericardium. Therefore, we are tempted to think of the pericardium as a virtual space containing only fluid, but it can also contain solid and ...

A Guide to Screening for Autoimmune Diseases in Patients With Vulvar Lichen Sclerosus

Australasian Journal of Dermatology, EarlyView.
ABSTRACTBackgroundThe aetiology of vulvar lichen sclerosus (VLS) remains unknown. However, there is evidence that in addition to a genetic predisposition, autoimmunity contributes to the pathogenesis.ObjectivesThe objective of this study was to determine the prevalence of autoimmune disease and positive autoantibody serology in patients with VLS ...

Disparity in spatial distribution of pericardial calcifications in constrictive pericarditis

Open Heart, 2018
Background Pericardial calcification is seen among patients with constrictive pericarditis (CP). However, the pattern of pericardial calcium distribution and the association with clinical outcomes and imaging data are not well described. Methods This was

Vaginal Deliveries Were as Safe as Cesarean Sections for the Long‐Term Cardiovascular Health of Preterm Twins

Acta Paediatrica, EarlyView.
ABSTRACT Aim There is no established consensus on the safest or most beneficial delivery mode for preterm twins. We assessed the associations between how premature twins were delivered and their long‐term cardiovascular morbidity during childhood. Methods A retrospective cohort study was conducted at the Soroka University Medical Center, the only ...

Treatment options for immune‐related adverse events associated with immune checkpoint inhibitors

British Journal of Pharmacology, EarlyView.
Abstract The immunotherapy revolution with the use of immune checkpoint inhibitors (ICIs) started with the clinical use of the first ICI, ipilimumab, in 2011. Since then, the field of ICI therapy has rapidly expanded — with the FDA approval of 10 different ICI drugs so far and their incorporation into the therapeutic regimens of a range of malignancies.

Diagnostic procedure for localized constrictive pericarditis leading to bilateral pleural effusion: two case reports

ESC Heart Failure
Constrictive pericarditis is a rare disease. Localized constrictive pericarditis leading to bilateral pleural effusion is more difficult to recognize, and the diagnostic procedure can be ambiguous.
