Developmental dynamics of symptoms of emotional problems in childhood and adolescence: A longitudinal network analysis

JCPP Advances, EarlyView.
This study examined how emotional symptoms co‐develop from childhood to adolescence using longitudinal data from over 11,000 children and adolescents. Network analyses revealed reciprocal links between core symptoms of anxiety and depression, with no significant differences between males and females.

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

The reporting and handling of missing data in genetic epidemiological studies of mental health in childhood and adolescence: A systematic review

JCPP Advances, EarlyView.
Abstract Background Genetic epidemiological analyses of child and adolescent mental health often use data from prospective longitudinal cohorts. Missingness due to selective attrition is therefore an important potential source of bias in such analyses.

The role of rare copy number variants in early‐onset depression

JCPP Advances, EarlyView.
Abstract Background Depression is a highly heterogeneous condition. Depression with an onset in childhood and early adolescence has a worse clinical course, is more heritable, and shows a lower genetic correlation with other depression subtypes, than does later‐onset depression.

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.

Unraveling Structure‐Dependent Performance of Cu–N–C Molecular Catalysts for Electrocatalytic CO2 Methanation

Small, EarlyView.
Copper phthalocyanine (CuPc) and copper tetraphenylporphyrin (CuPr) both contain Cu–N4 sites, yet CuPc shows superior CO2‐to‐CH4 selectivity. Further analysis suggests that the Pc‐macrocycle tunes the electronic structure of Cu center and induces charge transfer, possibly via its π‐conjugated Pc‐ring and bridge‐N environment.

Off‐Stoichiometric Synthesis of Porphyrin‐Based Covalent Organic Frameworks for Structural Modulation and Enhanced Chemiresistive NO2 Sensing

SusMat, EarlyView.
This study reports the sustainable synthesis of nanoscale porphyrin‐based covalent organic frameworks in aqueous solution under ambient conditions. By tuning the monomer stoichiometric ratio, defect‐rich structures are engineered within the framework, resulting in exceptional chemiresistive NO2 sensing performance, with a response of up to 7780 toward ...
