Mental health and healthcare use during COVID‐19 among neurodivergent youth and youth with pre‐existing psychiatric disorders: A systematic review

JCPP Advances, EarlyView.
Abstract Background Neurodivergent youth and youth with pre‐existing psychiatric disorders may have faced additional challenges in navigating the demands and restrictions of the COVID‐19 pandemic. However, less is known about how mental health outcomes and psychiatric healthcare utilization differed across diagnostic groups and other youth‐related ...

Analytical Modeling of MHD Flow over a Permeable Rotating Disk in the Presence of Soret and Dufour Effects: Entropy Analysis

Entropy, 2016
The main concern of the present article is to study steady magnetohydrodynamics (MHD) flow, heat transfer and entropy generation past a permeable rotating disk using a semi numerical/analytical method named Homotopy Analysis Method (HAM).

Stably Embedded Minimal Hypersurfaces

, 2007
We use Schoen-Simon-Yau's curvature estimates to prove that the subfocal tubular neighborhood of a non planar minimal hypersurface with bounded second fundamental form, stably embedded in R^{n+1}, n < 5, whose radius decays sufficiently slowly can not

Development and Characterization of Liposomes Containing a Zn(II) Porphyrin Derivative for the Application of Photodynamic Therapy in the Treatment of Breast Cancer

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives This study aims to synthesize and characterize lipid nanosystems (liposomes) for the incorporation of a Zn(II) porphyrin derivative, Zn(II) meso‐tetrakis(N‐n‐hexylpyridinium‐2‐yl)porphyrin (ZnTnHex‐2‐PyP4+, ZnPH), intending to employ an alternative method of treatment, such as photodynamic therapy (PDT), for breast cancer (BC ...

Radiation Effect on MHD Blood Flow Through a Tapered Porous Stenosed Artery with Thermal and Mass Diffusion

International Journal of Applied Mechanics and Engineering, 2019
A mathematical model for MHD blood flow through a stenosed artery with Soret and Dufour effects in the presence of thermal radiation has been studied. A uniform magnetic field is applied perpendicular to the porous surface.

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.

Rayleigh-Marangoni Instability of Binary Fluids with Small Lewis Number and Nano-Fluids in the Presence of the Soret Effect

Fluid Dynamics & Materials Processing, 2010
A general model for two-component transport phenomena applicable for both nanofluids and binary solutions is formulated. We investigate a combined long-wave Marangoni and Rayleigh instability of a quiescent state of a binary (nano-) liquid layer with a non-deformable free surface. The layer is heated from below or from above. The concentration gradient

Strain Rate Angle Distribution as an Indicator of Post‐Infarct Myocardial Remodeling: Proof‐of‐Concept of a Novel Application of the MRI Derived Strain Rate Tensor Field

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Left ventricular (LV) strain is an early indicator of myocardial dysfunction. However, conventional strain metrics do not fully account for the multidirectional nature of myocardial deformation. The strain rate tensor, derived from velocity‐encoded MRI, represents the time‐resolved magnitude and direction of strain rate without the ...
