Radiological Insights Into the Pericardium: A Comprehensive Review

open access: yesJournal 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 ...

Superior vena cava syndrome: a case report of a rare form of presentation [PDF]

open access: yes, 2018
Superior vena cava syndrome (SVCS) is the clinical manifestation of superior vena cava (SVC) obstruction, with severe reduction in venous return from the head, neck and upper extremities. It is a medical emergency. Obstruction to the SVC may be caused by

Enstrophy and Ergodicity of Gravity Currents [PDF]

open access: yesarXiv, 2004
We study a coupled deterministic system of vorticity evolution and salinity transport equations, with spatially correlated white noise on the boundary. This system may be considered as a model for gravity currents in oceanic fluids. The noise is due to uncertainty in salinity flux on fluid boundary.

Implantation of a Resynchronization Implantable Cardioverter Defibrillator in a Patient with Persistent Left Superior Vena Cava [PDF]

open access: yes, 2007
Implantation of resynchronization implantable cardioverter defibrillator was performed in a patient with persistent left superior vena cava. A dual coil defibrillation lead was inserted in the right ventricle apex via a small innominate vein.

On the number of monochromatic solutions of integer linear systems on Abelian groups [PDF]

open access: yesarXiv, 2012
Let $G$ be a finite abelian group with exponent $n$, and let $r$ be a positive integer. Let $A$ be a $k\times m$ matrix with integer entries. We show that if $A$ satisfies some natural conditions and $|G|$ is large enough then, for each $r$--coloring of $G\setminus \{0\}$, there is $\delta$ depending only on $r,n$ and $m$ such that the homogeneous ...

Prioritizing the Components of Vulnerability in a Genetic Algorithms Minimization of Flood Risk [PDF]

open access: yesarXiv, 2015
We compare two prioritization schemes for the components of flooding vulnerability: urbanized area ration, literacy rate, mortality rate, poverty, radio/tv penetration, non-structural measures and structural measure. We prioritize the components, giving each a weight. We then express the vulnerability function as a weighted sum of its components.
