Material Deprivation, Psychological Distress, and Substance Use Among Socioeconomically Disadvantaged Adolescents: The Mediating Roles of Social Relationships

open access: yesBehavioral Sciences &the Law, EarlyView.
ABSTRACT Previous research on the mediating role of the quality of social relationships between material deprivation and adolescent health has predominantly utilized samples from mainstream populations to examine mental health outcomes, neglecting the critical need to explore behavioral health outcomes, such as substance use, particularly in ...

Structural Revisions in Natural Ellagitannins

open access: yesMolecules, 2018
Ellagitannins are literally a class of tannins. Triggered by the oxidation of the phenolic parts on β-pentagalloyl-d-glucose, ellagitannins are generated through various structural conversions, such as the coupling of the phenolic parts, oxidation to ...

Hybridization of Guided Surface Acoustic Modes in Unconsolidated Granular Media by a Resonant Metasurface [PDF]

open access: yes, 2018
We investigate the interaction of guided surface acoustic modes (GSAMs) in unconsolidated granular media with a metasurface, consisting of an array of vertical oscillators.

Engineering Spin State of Ni Single‐Atoms to Enhance Electrocatalytic Activity of Sulfur Conversion in Lithium–Sulfur Batteries

open access: yesCarbon Energy, EarlyView.
Ni SACs with high‐spin state show strong catalytic activity toward lithium polysulfides (LPSs), whereas the Ni SACs with low‐spin state have strong adsorption capacity for LPSs. Therefore, the preparation of Ni SACs with an intermediate spin state by controlling pyridinic N and pyrrolic N enables an excellent balance between the adsorption and ...

Subthreshold rho^0 photoproduction on 3He

open access: yes, 1998
A large reduction of the rho^0 mass in the nuclear medium is reported, inferred from dipion photoproduction spectra in the 1 GeV region, for the reaction 3He(gamma,pi+ pi-)X with a 10% duty factor tagged-photon beam and the TAGX multi-particle ...

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Chemo‐Enzymatic Route for Covalent Cellulose Fiber Dyeing

open access: yesChemistry – A European Journal, EarlyView.
This work presents a proof of concept for a chemo‐enzymatic approach to the covalent dyeing of cotton fibers. Laccase/TEMPO oxidation introduces aldehyde groups, enabling subsequent reductive amination with amino dyes. Excellent color homogeneity and wash fastness were demonstrated using acid red 33, highlighting the robustness of the approach and its ...

Heterozygous Med13l mice recapitulate a developmental growth delay and craniofacial anomalies seen in MED13L syndrome

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Gene transcription is crucial for embryo and postnatal development and is regulated by the Mediator complex. Mediator is comprised of four submodules, including the kinase submodule (CKM). The CKM consists of MED13, MED12, CDK8, and CCNC.

The status of the Pacific sardine resource and its management [PDF]

open access: yes, 1973
The Pacific sardine fishery has declined from a catch of almost 8 hundred-thousand tons in the nineteen thirties to relative insignificance at present. This decline was primarily due to the decline of the northern subpopulation.
