Association Between Carotid Artery Function and Structure in the Northern Manhattan Study

Frontiers in Neurology, 2018
Background and purposeCarotid plaque (CP), carotid intima media thickness (cIMT), and stiffness (STIFF) are pre-clinical markers of atherosclerosis and predictors of cerebrovascular disease (CVD).

Stability criterion for self-similar solutions with a scalar field and those with a stiff fluid in general relativity

, 2003
A stability criterion is derived in general relativity for self-similar solutions with a scalar field and those with a stiff fluid, which is a perfect fluid with the equation of state $P=\rho$.

Stiff-Glass Approximation of Mode-Coupling Theory [PDF]

, 2001
The stiff-glass approximation of the mode-coupling theory of the glass-transition--as introduced in a recent paper by G\"otze and Mayr for a discussion of phenomena resembling the Boson Peak and High-Frequency Sound observations made in real glass ...

Cosmology with a stiff matter era

, 2014
We provide a simple analytical solution of the Friedmann equations for a universe made of stiff matter, dust matter, and dark energy. A stiff matter era is present in the cosmological model of Zel'dovich (1972) where the primordial universe is assumed to

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Stiff Arteries, Stiff Ventricles [PDF]

Circulation: Cardiovascular Imaging, 2016
The biophysical properties and neurohormonal regulation of arterial function are influential mediators of cardiovascular disease. Over the past 3 decades, the prognostic importance of arterial stiffness, as a measurable indicator of arterial function, has been recognized in both unselected populations and among patients with cardiovascular risk factors.

Elasticity of Stiff Polymer Networks

, 2003
We study the elasticity of a two-dimensional random network of rigid rods (``Mikado model''). The essential features incorporated into the model are the anisotropic elasticity of the rods and the random geometry of the network.

Crumpling of a stiff tethered membrane [PDF]

, 2003
first-principles numerical simulation model for crumpling of a stiff tethered membrane is introduced. In our model membranes, wrinkles, ridge formation, ridge collapse, as well as the initiation of stiffness divergence, are observed.
