Temperature dependent rate coefficients for the gas-phase OH + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction (open access)

Temperature dependent rate coefficients for the gas-phase OH + Furan-2,5-dione (C4H2O3, maleic anhydride) reaction

Authors of the article assert that rate coefficients, k1(T), for the gas-phase reaction of the OH radical with Furan-2,5-dione (maleic anhydride (MA), C4H2O3), a biomass burning related compound, were measured under pseudo first-order conditions in OH using the pulsed laser photolysis - laser induced fluorescence method over a range of temperature and bath gas pressure. Their results are compared with a previous room temperature relative rate study of the OH + MA reaction and significant discrepancy between the studies is discussed. This is the accepted manuscript version of the published article.

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.

Three Component Cascade Reaction of Cyclohexanones, Aryl Amines, and Benzoylmethylene Malonates: Cooperative Enamine-Brønsted Acid Approach to Tetrahydroindoles (open access)

Three Component Cascade Reaction of Cyclohexanones, Aryl Amines, and Benzoylmethylene Malonates: Cooperative Enamine-Brønsted Acid Approach to Tetrahydroindoles

Article discusses how a three-component cascade reaction comprising cyclic ketones, arylamines, and benzoylmethylene malonates has been developed to access 4,5,6,7-tetrahydro-1H-indoles. Furthermore, the reaction was achieved through cooperative enamine-Brønsted catalysis in high yields with wide substrate scopes.

Using an Adjunctive Treatment to Address Psychological Distress in a National Weight Management Program: Results of an Integrated Pilot Study (open access)

Using an Adjunctive Treatment to Address Psychological Distress in a National Weight Management Program: Results of an Integrated Pilot Study

Article examining weight loss and physical functioning of obese veterans with comorbid psychological symptoms when participating in weight management programs. The MOVE! program aims to increase healthy eating and physical activity to promote weight loss in obese veterans. Adequately addressing psychological barriers is necessary to maximize outcomes in MOVE! for veterans with PTSD, depression, and anxiety. This study examined the preliminary outcomes of administering the Healthy Emotions and Improving Health BehavioR Outcomes (HERO) intervention. HERO is adjunctive cognitive-behavioral therapy to MOVE! that addresses PTSD, depression, and anxiety symptom barriers to engagement in physical activity.
