Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Rheology of compressible and density-variable Newtonian flows: non-Stokes hypothesis and ‘volume diffusion’

Journal of Physics Communications
Stokes’ hypothesis allows for the frequent neglect of the bulk viscosity term related to fluid dilation effects on the viscous stress tensor in Newtonian flows.

And\^o dilations for a pair of commuting contractions: two explicit constructions and functional models

, 2014
One of the most important results in operator theory is And\^o's \cite{ando} generalization of dilation theory for a single contraction to a pair of commuting contractions acting on a Hilbert space. While there are two explicit constructions (Sch\"affer \

Interference of Clocks: A Quantum Twin Paradox [PDF]

, 2019
The phase of matter waves depends on proper time and is therefore susceptible to special-relativistic (kinematic) and gravitational time dilation (redshift).

Dilation equations and Markov operators

Journal of Mathematical Analysis and Applications, 2005
Using the theory of Markov operators \(P: L^1(X)\to L^1(X)\) with \(P\) linear, \(\| Pf\|_1=\| f\|_1= 1\) for \(f\geq 0\), \(f\in L^1(X)\), the author gives a new proof for the following Theorem. Let \(N,k> 1\) be positive integers and \(c_0,\dots, c_N\geq 0\) be reals such that \(\sum^\infty_{i=0} c_{ki+j}= 1\) for every \(j\in \{0,\dots,k- 1 ...

Age‐Related Characteristics of SYT1‐Associated Neurodevelopmental Disorder

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We describe the clinical manifestations and developmental abilities of individuals with SYT1‐associated neurodevelopmental disorder (Baker‐Gordon syndrome) from infancy to adulthood. We further describe the neuroradiological and electrophysiological characteristics of the condition at different ages, and explore the associations ...

The maximal acceleration, Extended Relativistic Dynamics and Doppler type shift for an accelerated source

, 2010
Based on the generalized principle of relativity and the ensuing symmetry, we have shown that there are only two possible types of transformations between uniformly accelerated systems.

Variable Dilation Angle Models in Rocks, a Review

Applied Sciences
This paper presents a comprehensive review of dilation angle models in rock mechanics. Dilation, a characteristic behavior of geomaterials, such as rocks and rock masses, involves volumetric changes during plastic deformation.
