Appearance of the canine meninges in subtraction magnetic resonance images [PDF]

open access: yes, 2014
The canine meninges are not visible as discrete structures in noncontrast magnetic resonance (MR) images, and are incompletely visualized in T1‐weighted, postgadolinium images, reportedly appearing as short, thin curvilinear segments with minimal ...

Evaluation of the role of FMR1 CGG repeat allele in Parkinson’s disease from the Chinese population

open access: yesFrontiers in Aging Neuroscience, 2023
ObjectiveThere is controversial evidence that FMR1 premutation or “gray zone” (GZ) allele (small CGG expansion, 45–54 repeats) was associated with Parkinson’s disease (PD).

Shades of Gray in the War in Eastern Ukraine: ‘Neither War nor Peace’ Existence Zones, ‘Neither Truth nor Lie’ Silence Zones

open access: yesBaltic Journal of European studies, 2019
The concepts of ‘gray zone conflict’, as one of the new phenomena in the theory of international relations, are given considerable attention in modern strategic researches of analysts, in particular American ones (Hel Brands, Adam Elkus, etc.).

Simulating Real Atmospheric Boundary Layers at Gray-Zone Resolutions: How Do Currently Available Turbulence Parameterizations Perform?

open access: yesAtmosphere, 2020
Recent computational and modeling advances have led a diverse modeling community to experiment with atmospheric boundary layer (ABL) simulations at subkilometer horizontal scales. Accurately parameterizing turbulence at these scales is a complex problem.

Visualizing Spacetime Curvature via Frame-Drag Vortexes and Tidal Tendexes III. Quasinormal Pulsations of Schwarzschild and Kerr Black Holes [PDF]

open access: yes, 2012
In recent papers, we and colleagues have introduced a way to visualize the full vacuum Riemann curvature tensor using frame-drag vortex lines and their vorticities, and tidal tendex lines and their tendicities.

Victim or Perpetrator? Uncovering the Nuances of Perpetrators in Graphic Narratives

open access: yesOn_Culture, 2021
Graphic narratives about genocide allow for different and unique ways of visualizing and imagining trauma and trauma-induced subjective experiences. In their attempt to initiate active reader participation in filling in the gutters with reader-induced ...

Influence of Microscopic Effects on the Static Tensile Strength of Gray Cast Iron HT200 Specimens

open access: yesAdvances in Materials Science and Engineering, 2021
Gray cast iron HT200 material is a kind of pearlitic gray cast iron. Flake graphite in the gray cast iron greatly destroys the integrity of the matrix and affect the static strength.

Quantum Fluctuations in Josephson Junction Comparators

open access: yes, 2002
We have developed a method for calculation of quantum fluctuation effects, in particular of the uncertainty zone developing at the potential curvature sign inversion, for a damped harmonic oscillator with arbitrary time dependence of frequency and for ...
