Reaction-Diffusion in Co2Si/Zn Diffusion Couple
Periodic layered structures were examined in the Co₂Si/Zn diffusion couple annealed at 390 °C. SEM, TEM, EPMA, and XRD analyses revealed alternating Co–Si–rich and Zn–rich layers composed of CoSi, γ₁, and γ₂ phases with cell-to-cell variations in ...

Narcolepsy and rapid eye movement sleep
Journal of Sleep Research, Volume 34, Issue 2, April 2025.Summary Since the first description of narcolepsy at the end of the 19th Century, great progress has been made. The disease is nowadays distinguished as narcolepsy type 1 and type 2. In the 1960s, the discovery of rapid eye movement sleep at sleep onset led to improved understanding of core sleep‐related disease symptoms of the disease (excessive ...

Neuropsychopharmacology Reports, Volume 46, Issue 4, December 2026.We report a case of neurosyphilis characterized by early‐onset dementia, limbic encephalitis, and normal pressure hydrocephalus. Psychiatrists should be aware of the possibility of neurosyphilis in such cases. ABSTRACT Background Neurosyphilis may present with a variety of clinical symptoms and neuroimaging findings and is thus likely to be overlooked.

Modeling brain extracellular space from diffusion data [PDF]
, 2007 The extracellular space (ECS) of the brain is a thin region surrounding each cell that is filled with a medium resembling cerebrospinal fluid and an unknown amount of extracellular matrix. The ECS is difficult to study but diffusion measurements based on

Effective Crack Resistance of a Simplified Ductile Heterogeneous Material With Circular Inclusions
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT This contribution investigates the effective crack resistance obtained from a numerical crack‐growth experiment for a simplified two‐dimensional ductile heterogeneous material. The resolved microstructure contains circular inclusions. Their stiffness and fracture resistance are varied independently together with the ligament width between ...

Two-Dimensional Unsteady-State Problem of Elasticity with Diffusion for Isotropic One-Component Half-Plane [PDF]
Учёные записки Казанского университета: Серия Физико-математические науки, 2015 A two-dimensional unsteady-state problem for the isotropic elastic half-plane with diffusion effect is investigated in this paper. In order to solve the problem, the local-equilibrium model of mechanical diffusion is used. This model consists of a system

Forecasting Cascading and Compounding Flood Risk From Earthquake‐Induced Ground Deformation
Journal of Flood Risk Management, Volume 19, Issue 4, December 2026.ABSTRACT Large earthquakes can disrupt river systems and produce abrupt, unforeseen changes in flood risk. Forward modelling of earthquake‐related surface deformation and its influence on inundation extent, depth, and frequency enables pre‐emptive assessment of exposure to this compound hazard.

Robust estimator framework in diffusion tensor imaging [PDF]
, 2013 Diffusion of water molecules in the human brain tissue has strong similarities with diffusion in porous media. It is affected by different factors such as restrictions and compartmentalization, interaction with membrane walls, strong anisotropy imposed ...

Moisture Effects on the Dimensional Stability of Bistable Carbon/Epoxy Laminates
Polymer Composites, Volume 47, Issue 19, Page 17449-17460, 10 October 2026.Experimental and numerical approach for studying moisture effects on composite dimensional stability. ABSTRACT Bistable composite laminates are attractive because they can switch between two stable shapes without continuous energy input, enabling applications in morphing structures and energy harvesting devices.
