Conductance and current noise of a superconductor/ferromagnet quantum point contact

, 2008
We study the conductance and current noise of a superconductor/ferromagnet (S/F) single channel Quantum Point Contact (QPC) as a function of the QPC bias voltage, using a scattering approach.

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

The Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Mechanisms of Smooth Muscle Cell Differentiation Are Distinctly Altered in Thoracic Aortic Aneurysms Associated with Bicuspid or Tricuspid Aortic Valves

Frontiers in Physiology, 2017
Cellular and molecular mechanisms of thoracic aortic aneurysm are not clear and therapeutic approaches are mostly absent. Thoracic aortic aneurysm is associated with defective differentiation of smooth muscle cells (SMC) of aortic wall.

Departing from standard practices: Strategic application of value engineering in the anatomy laboratory to enhance formaldehyde extraction using high‐impact, low‐cost, and low‐maintenance solutions

Anatomical Sciences Education, Volume 18, Issue 3, Page 241-253, March 2025.
Abstract This study describes the process of developing a high‐impact, low‐cost, and low‐maintenance air ventilation system for anatomy facilities. It employed the strategic application of Value Engineering (VE), assuring that the air ventilation system meets contemporary threshold limit values (TLVs) for formaldehyde in the working zone of dissection ...

Predicting Coronary Occlusion Risk during Redo‐TAVR at First TAVR: Asymmetric Calcification Causes Failure

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aims Predicting coronary artery occlusion due to sinus sequestration (SS) during a second transcatheter aortic valve (TAV) procedure using pre‐procedural computed tomography (CT) after the first TAV replacement (TAVR) is underreported.

Long‐Term Durability of Transcatheter Aortic Valve Prostheses in Patients With Bicuspid Versus Tricuspid Aortic Valve

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Currently, there is a lack of evidence for the long‐term bioprosthetic valve durability of patients with bicuspid aortic valve (BAV) following transcatheter aortic valve replacement (TAVR).

Single Centre Experience With the Balloon‐Expandable Myval Transcatheter Aortic Valve System in Patients With Bicuspid Anatomy: 1 Year Follow‐Up

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BAV) anatomy remains challenging due to anatomical complexity and limited trial data. New‐generation balloon‐expandable valves, such as Myval, require further evaluation in this subgroup.

Thoracic aortic atherosclerosis in patients with a bicuspid aortic valve; a case–control study

BMC Cardiovascular Disorders, 2023
Introduction Bicuspid aortic valve (BAV) patients have an increased risk to develop thoracic aortic complications. Little is known about the prevalence and severity of atherosclerosis in the BAV ascending aortic wall.
