J Colloid Interface Sci 2018 Nov 23;538:597-604. Epub 2018 Nov 23.

National Engineering Lab for TFT-LCD Materials and Technologies, Department of Electronic Engineering, Shanghai Jiao Tong University, 800 Dongchuan Road, Shanghai 200240, People's Republic of China. Electronic address:

An acid-pasting approach is developed in this work to fabricate the composite of perylenetetracarboxylic diimide (PTCDI) and carbon black in concentrated sulfuric acid. Different from traditional mechanical mixing, the solution-based fabrication strategy enables the sufficient blending of PTCDI as active component and carbon black as conductive agent in the PTCDI/CB composite. Serving as the cathode material, the PTCDI/CB composite shows excellent electrochemical performances in both lithium ion battery (137 mAh g at 100 mA g and 110 mAh g at 2000 mA g) and sodium ion battery (134 mAh g at 100 mA g and 99 mAh g at 1000 mA g), which are comparable to the state-of-art organic/inorganic cathode materials.

Fam Process 2018 Dec 15. Epub 2018 Dec 15.

Graduate School of Education, University of Pennsylvania, Philadelphia, PA.

Researchers have illustrated the deleterious psychological effects that racial discrimination has exerted on Black Americans. The resulting racial stress and trauma (RST) from experiences with discrimination has been linked to negative wellness outcomes and trajectories for Black youth and families. Racial socialization (RS)-defined as the verbal and nonverbal messages that families use to communicate race to their children-can be a cultural strength and has been associated with positive outcomes in Black youth.

NonPrimordial Solar Mass Black Holes.

Phys Rev Lett 2018 Nov;121(22):221102

Service de Physique Théorique, Université Libre de Bruxelles (ULB), CP225 Boulevard du Triomphe, B-1050 Bruxelles, Belgium.

We propose a mechanism that can convert a sizable fraction of neutron stars into black holes with mass ∼1  M_{⊙}, too light to be produced via stellar evolution. We show that asymmetric fermionic dark matter of mass on the teraelectron volt scale, with attractive self-interaction within the range that alleviates the problems of collisionless cold dark matter, can accumulate in a neutron star and collapse, forming a black hole that converts the rest of the star to a solar mass black hole. We estimate the fraction of neutron stars that can become black holes without contradicting neutron star observations. Read More

Optimal Design of Energy Systems Using Constrained Grey-Box Multi-Objective Optimization.

Comput Chem Eng 2018 Aug 21;116:488-502. Epub 2018 Feb 21.

Artie McFerrin Department of Chemical Engineering, Texas A&M University, College Station, TX 77843, USA.

The (global) optimization of energy systems, commonly characterized by high-fidelity and large-scale complex models, poses a formidable challenge partially due to the high noise and/or computational expense associated with the calculation of derivatives. This complexity is further amplified in the presence of multiple conflicting objectives, for which the goal is to generate trade-off compromise solutions, commonly known as solutions. We have previously introduced the p-ARGONAUT system, parallel AlgoRithms for Global Optimization of coNstrAined grey-box compUTational problems, which is designed to optimize general constrained single objective grey-box problems by postulating accurate and tractable surrogate formulations for all unknown equations in a computationally efficient manner.

Dopamine perturbation of gene co-expression networks reveals differential response in schizophrenia for translational machinery.

Transl Psychiatry 2018 Dec 13;8(1):278. Epub 2018 Dec 13.

South Texas Diabetes and Obesity Institute, Department of Human Genetics, University of Texas Rio Grande Valley School of Medicine, San Antonio, TX, USA.

The dopaminergic hypothesis of schizophrenia (SZ) postulates that positive symptoms of SZ, in particular psychosis, are due to disturbed neurotransmission via the dopamine (DA) receptor D2 (DRD2). However, DA is a reactive molecule that yields various oxidative species, and thus has important non-receptor-mediated effects, with empirical evidence of cellular toxicity and neurodegeneration. Here we examine non-receptor-mediated effects of DA on gene co-expression networks and its potential role in SZ pathology. Read More

Hepatitis C virus direct-acting antiviral nonadherence: Relationship to sustained virologic response and identification of at-risk patients.

J Am Pharm Assoc (2003) 2018 Dec 10. Epub 2018 Dec 10.

Objectives: There is a dearth of literature on effects of nonadherence to hepatitis C virus (HCV) direct-acting antiviral (DAA) regimens; thus, the objective of our study was to assess the impact of adherence on sustained virologic response (SVR) and evaluate factors associated with nonadherence, such as race, psychiatric comorbidities, and therapy length.

Methods: We conducted a retrospective cohort study of patients completing DAA treatment between January 2014 and May 2016 within an interdisciplinary hepatology clinic. Adherence was defined a priori as 95% or greater of DAA doses taken within the prescribed treatment period. Read More

Gender Differences in the Quality of EMS Care Nationwide for Chest Pain and Out-of- Hospital Cardiac Arrest.

Womens Health Issues 2018 Nov 24. Epub 2018 Nov 24.

Milken Institute School of Public Health, George Washington University, Washington, DC. Electronic address:

Background: We sought to determine whether gender disparities exist in the prehospital management of chest pain (CP) or out-of-hospital cardiac arrest (OHCA) among patients who accessed the emergency medical services (EMS) system.

Methods: We obtained 2010-2013 data from the National Emergency Medical Services Information System and identified all EMS activations for CP or OHCA by adults 40 years of age or older. We selected American Heart Association medications and procedures to manage cardiovascular events. Read More
