Computational study of the gas-phase reactions of sulfuric acid with OH(ΠJ), O(3PJ), Cl(2P) and O(1D2) radicals
This article is about how rate coefficients for reactions of H2SO4 with OH, O(3P) and Cl radicals over 160–298 K were estimated computationally. The authors propose kOH = 8.5 × 10-14 exp(-50 K/T), kO = 1.1 × 10-12 exp(-5012 K/T) and kCl = 3.1 × 10-9 exp(-3314 K/T) cm3 molecule-1 s−1.

Ignition delay times of NH3/DME blends at high pressure and low DME fraction: RCM experiments and simulations
Authors of the article describe how autoignition delay times of ammonia/dimethyl ether (NH3/DME) mixtures were measured in a rapid compression machine with DME fractions of 0, 2 and 5 and 100% in the fuel. Analysis of the mechanism indicates that this 'early DME oxidation' generates reactive species that initiate the oxidation of ammonia, which in turn begins heat release that raises the temperature and accelerates the oxidation process towards ignition. This is the accepted manuscript version of the published article.

Acetaldehyde oxidation at elevated pressure
A detailed chemical kinetic model for oxidation of CH3CHO at intermediate to high temperature and elevated pressure has been developed and evaluated by comparing predictions to novel high-pressure flow reactor experiments as well as shock tube ignition delay measurements and jet-stirred reactor data from literature. The flow reactor experiments were conducted with a slightly lean CH3CHO/O2 mixture highly diluted in N2 at 600–900 K and pressures of 25 and 100 bar. This is the accepted manuscript version of the published article.

Experimental and kinetic modeling study of oxidation of acetonitrile
Article asserts that oxidation of acetonitrile has been studied in a flow reactor in the absence and presence of nitric oxide. A detailed chemical kinetic model for oxidation of acetonitrile was developed, based on a critical evaluation of data from literature. This is the accepted manuscript version of the published article.

Selective Noncatalytic Reduction of NOx Using Ammonium Sulfate
Article discusses how ammonium sulfate (AS) is of interest as an additive in stationary combustion plants for the simultaneous control of NOx (through selective noncatalytic reduction, SNCR) and deposition and corrosion (through sulfation of alkali chlorides). The results indicated that sulfur from ammonium sulfate is mainly released as SO3, even though SO2 is detected in increasing concentrations at temperatures above 1000 °C. This is the accepted manuscript version of the published article.

Kinetic fall-off behavior for the Cl + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction
Article discusses how rate coefficients, k, for the gas-phase Cl + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction were measured over the 15–500 torr (He and N2 bath gas) pressure range at temperatures between 283 and 323 K. An atmospheric degradation mechanism for C4H2O3 is proposed based on the observed product yields and theoretical calculations of ring-opening pathways and activation barrier energies at the CBS-QB3 level of theory. This is the accepted manuscript version of the published article.

New reactions of diazene and related species for modelling combustion of amine fuels
Article discusses how potential energy surfaces for reactions involving N2H2 isomers of diazene (diimide) have been explored using density functional theory, with energies based on coupled-cluster theory. A focus is on processes that create or consume these species, and isomerization between the E (trans) and Z (cis) forms of HNNH. This is the accepted manuscript version of the published article.

Elucidating the role of negative parenting in the genetic v. environmental influences on adult psychopathic traits
Article states that though adult psychopathic traits emerge from both genetic and environmental risk, no studies have examined etiologic associations between adult psychopathic traits and experiences of parenting in childhood, or the extent to which parenting practices may impact the heritability of adult psychopathic traits using a genetically-informed design. Utilizing a genetically-informed design, the authors found that both genetic and non-shared environmental factors contribute to the emergence of psychopathic traits.

Temporal Variations and Spatial Disparities in Public Sentiment Toward COVID-19 and Preventive Practices in the United States: Infodemiology Study of Tweets
Article discusses how, during the COVID-19 pandemic, US public health authorities and county, state, and federal governments recommended or ordered certain preventative practices, such as wearing masks, to reduce the spread of the disease. The purpose of this study was to understand the variations in public sentiment toward COVID-19 and the recommended or ordered preventive practices from the temporal and spatial perspectives, as well as how the variations in public sentiment are related to geographical and socioeconomic factors.

Spatial and temporal localization of SPIRRIG and WAVE/SCAR reveal roles for these proteins in actin-mediated root hair development
Article shows that SPIRRIG (SPI), a beige and Chediak Higashi domain-containing protein involved in membrane trafficking, and BRK1 and SCAR2, subunits of the WAVE/SCAR (W/SC) actin nucleating promoting complex, display polarized localizations in Arabidopsis thaliana root hairs during distinct developmental stages. Authors' work uncovers a role for SPI in facilitating actin-dependent root hair development in Arabidopsis through pathways that might intersect with W/SC.

Descriptive Complexity in Cantor Series
Article discusses how a Cantor series expansion for a real number x with respect to a basic sequence Q=(q), where qi≥2, is a generalization of the base b expansion to an infinite sequence of bases. The authors show that for any basic sequence the set of distribution normal numbers is Π03-complete, and if Q is 1-divergent then the sets of normal and ratio normal numbers are Π03-complete.

Near-Death Experiences and Claims of Past-Life Memories
Article discussing the role of life reviews during near-death experiences (NDEs) and situations in which those experiences have included memories that appear to be from a previous lifetime. It also addresses the apparent contradiction that some NDErs report meeting deceased persons in a non-Earthly realm.
