By drawing on one of the core constructs from information theory-information entropy-I argue that combining the two streams of psychology would result in the most significant advancement of psychological knowledge.Objective Assess physical activity (PA) and nutrition recommendation knowledge in college students. Participants 71 students (n = 41 females;18 to 22 years) measured in May of 2014. METHODS Knowledge of existence and accuracy of PA and nutrition recommendations were assessed via a verbal survey. Results Most (67.6%) were aware PA recommendations exist, but only 26.8% could accurately report them. Almost all (91.5%) were aware nutrition guidelines exist, but no higher than 23.9% answered any specific recommendation correctly.  https://www.selleckchem.com/products/ots964.html  There were no significant associations between sex or body mass index (BMI) and either awareness or accuracy of PA or nutrition recommendations. Non-Kinesiology majors were 3.3 times more likely to answer that they were not aware of the existence of PA recommendations, compared to Kinesiology majors. Conclusions Accurate knowledge of the PA and nutrition recommendations are very low and given that the majority of participants were categorized as overweight or obese, teaching these guidelines needs to be the priority.Conventional exciplexes are products of excited-state charge generation reactions between neutral reactants (e.g., A* + D → A•-D•+), whereas cationic exciplexes are products of charge shift reactions of cations with neutral donors (e.g., A+* + D → A•D•+). Compared herein is the solvent-dependent fluorescence of a cationic exciplex with extant data for conventional exciplexes. Although linear correlations of conventional exciplex emission maxima with the Lippert-Mataga solvent polarity function are well documented in low to moderate polarity solvents, the correlations are often poor in more polar solvents. A number of such plots in moderate to high polarity solvents show a strong curvature. Intriguingly, for these same cases, plots of emission maxima versus the solvent dielectric constant (ε) are remarkably linear. Interestingly, emission maxima for the cationic exciplex of 1+ in nitrile and alcohol solvents also correlate linearly with ε. The solvent dependency for cationic exciplex emission maxima on ε is ca 1/3 of that for conventional exciplexes, which is ascribed to solvent stabilization of both the excited state and the ground state for cationic exciplexes. Differences in exciplex emissions between nitrile and alcohol solvents for 1+ are attributed to hydrogen bonding, with larger differences in higher hydrogen-bond acidity solvents.Enhanced electromagnetic fields in nanometer gaps of plasmonic structures increase the optical interaction with matter, including Raman scattering and optical absorption. Quantum electron tunneling across sub-1 nm gaps, however, lowers these effects again. Understanding these phenomena requires controlled variation of gap sizes. Mechanically actuated plasmonic antennas enable repeatable tuning of gap sizes from the weak-coupling over the quantum-electron-tunneling to the direct-electrical-contact regime. Gap sizes are controlled electrically via leads that only weakly disturb plasmonic modes. Conductance signals show a near-continuous transition from electron tunneling to metallic contact. As the antenna's absorption cross-section is reduced, thermal expansion effects are negligible, in contrast to conventional break-junctions. Optical scattering spectra reveal first continuous red shifts for decreasing gap sizes and then blue shifts below gaps of 0.3 nm. The approach provides pathways to study opto- and electromolecular processes at the limit of plasmonic sensing.Microplastics in the air have gradually attracted our attention in recent years; however, temporal and spatial trends of microplastics in indoor air are rarely discussed. In the present study, we tracked microplastic fallout in a dormitory, an office and a corridor on both workdays and weekends for three months. In addition, an air conditioner was used to understand airflow influence on microplastic resuspension in the dorm. Among the three sampling sites, the highest average microplastic abundance appeared in the dormitory (9.9×103 MPs/m2/d), followed by the office (1.8×103 MPs/m2/d) and the corridor (1.5×103 MPs/m2/d). In the dormitory, the average MP abundance on weekends (1.4×104 MPs/m2/d) was approximately three times of that on weekdays (5.8×103 MPs/m2/d). In the office, however, the abundance on weekends (1.2×103 MPs/m2/d) was 50% of that on weekdays (2.4×103 MPs/m2/d). Microplastic fallout existed mostly in the form of fibers and showed similar polymer compositions to the textile products used in indoor environments. The airflow tests using air conditioner suggested that airflow turbulence increased resuspension of microplastics. Taken together, we conclude that indoor environments are prone to serious microplastic pollution but microplastic level varies greatly due to different characteristics of indoor setting. Our results also indicate that textile quantity is one of the main factors affecting microplastic abundance in indoor air, while air conditioner-induced airflow turbulence can cause microplastic migration in indoor environments.Enzyme engineering for gain of function requires navigating a large combinatorial sequence space efficiently. Typically, many mutations are needed to get significant improvements, while a single "bad" mutation can inactivate the enzyme. To establish high-throughput screening and achieve enhanced resolution between two variants, genetic libraries of the organophosphate hydrolase enzyme paraoxonase 1 (PON1) were rapidly screened via an engineered positive-feedback circuit a p-nitrophenol (PNP)-specific transcription factor (TF) regulated expression of PON1, which catalyzed paraoxon breakdown and PNP production. Rare active mutant colonies, picked by simple visual fluorescence of a PON1-green fluorescent protein (GFP) fusion, were characterized. In a single screening round, high (library-scale) throughput enabled the discovery of enhanced paraoxon degradation activity in PON1, including structurally unexpected mutations.
