AbstractTo evaluate the reactive energy release of the Al/Polytetrafluoroethylene (PTFE) mixed powder (Al and PTFE with a mass percentage of 26.5%/73.5%). Based on the traditional formula, three kinds of Al/PTFE test samples with different dosages (4, 6.5, and 9 g) were mixed. By using the self-designed airtight container, and combining with the overpressure sensor, the transient optical fiber pyrometer, and the infrared thermography. The overpressure , the visible light radiation temperature in the closed container, and the infrared light radiant temperature of the container’s outer wall have been obtained by real-time measurements during the process of cooking off, and the reaction products are analyzed by X-ray energy spectrum (EDS) and X- ray diffraction (XRD). The experimental results show that most of the solid products of Al/PTFE powder in the closed container are AlF3 and a small number of intermediate carbon compositions. The released energy during the firing process of the active material Al/PTFE increases with the increase of the mixing amount; The bake-off energy of active material Al/PTFE mixture per unit mass in a closed container is about 10.2 kJ/g, and when the oxygen content in the closed container is sufficient, active material Al/PTFE per unit mass releases more energy.
Children’s non-adultlike interpretations of telic predicates across languages

Published: September 2020

AbstractThe acquisition literature has documented several different types of misinterpretations of telic sentences by children, yet a comprehensive analysis of these child interpretations has not been attempted and a crosslinguistic perspective is lacking. This task is not easy, for, on the surface, children’s non-adultlike interpretations appear to be scattered and even contradictory across languages. Several cognitive biases have been proposed to explain given patterns (children initially adhere to a Manner bias, or alternatively a Result bias). Reviewing a wide range of studies on the acquisition of telic sentences in relation to tense-aspect markers, we show that children’s non-adultlike interpretations fall into three different patterns. We conclude that the diversity of non-adultlike interpretations that is found across child languages is incompatible with accounts that rely on these cognitive, language-independent principles, but instead is triggered by language-specific properties. Analyzing these patterns in detail, it appears that child learners across languages have problems with tense-aspect forms with variable meanings, in contrast to forms with a one-to-one form/meaning mappings which are acquired earlier. While adults use a context-sensitive interpretation of forms with multiple meanings, various semantic-pragmatic sources can explain children’s difficulties with interpreting such forms. All explanations that we identify across child languages rely on children’s immature command of pragmatic reasoning, albeit in very different ways for the three different patterns. Thus, by taking a crosslinguistic semantic approach and integrating detailed insights from the tense-aspect semantics of specific languages with universal pragmatic effects, we explain the non-adultlike interpretation of telic sentences in a variety of child languages in a comprehensive way.

Published: September 2020

Abstract
KCl72H2SeO3 and CsCl7H2SeO3 have been synthesized using solution evaporation methods from aqueous solution. Both compounds are monoclinic (P2/n and P21/c) and demonstrate new structure types. One symmetrically unique SeO(OH)2 molecule is present in each structure. SeO(OH)2 molecules via strong hydrogen bonds form chains in KCl72H2SeO3 and layers in ?sCl7H2SeO3. The structures of KCl72H2SeO3 and CsCl7H2SeO3 can be described as consisting of ionic KCl chains and CsCl layers incorporated into the covalent- and hydrogen-bonded H2SeO3 matrix. To the best of our knowledge, the cases when selenious acid acts as a contributor to the molecular building blocks of salt-inclusion structures are not known to date.

Published: September 2020

Abstract
The methanol extract and its ethyl acetate fraction (EAF) of Actaea acuminata (Wall. ex. Royle) H. Hara roots were reported to exhibit significant antianxiety, anticonvulsant and antidepressant activities, and mild sedative activity. But the constituents responsible for these activities have not been isolated. The present study was undertaken to isolate neuroprotective compounds of A. acuminata following bioactivity-guided-fractionation. The column chromatography of EAF and its sub-fractions led to the isolation of four phenolic compounds (bergenin, gallic acid, acetyl bergenin and racemic mixture of diacetyl bergenin), which were characterized by IR and NMR spectral analysis. All the compounds exhibited significant antianxiety and antidepressant activities with respect to control. The gallic acid and bergenin did not show anticonvulsant activity, whereas acetyl bergenin and racemic mixture of diacetyl bergenin exhibited significant anticonvulsant activity. Neuropharmacological activities of A. acuminata are attributed due to polyphenolic compounds. Scientific validation of traditional claims of A. acuminata has opened up roadmap of research for the development of CNS affecting lead molecules.

The influence of Pilates exercises on body composition, muscle strength, and gait speed in community-dwelling older women: a randomized controlled trial. J Strength Cond Res 36(8): 2298–2305, 2022—Population aging is a global phenomenon that has wide-ranging consequences for the health of individuals, including age-related obesity, muscle loss, and a decline in muscle strength and gait speed. These alterations are associated with disability, functional decline, and mortality in older adults. The objective of this study was to analyze the effects of Pilates exercises on body composition, handgrip strength, and physical performance among community-dwelling Spanish women aged 60 and older. A randomized controlled trial of a 12-week Pilates training program was conducted. A total of 109 women were randomly allocated to either a control (n = 54) or a Pilates (n = 55) group. Body composition was evaluated by bioelectrical impedance. Body mass index (BMI), percentage of body fat, and height-adjusted skeletal muscle mass index (SMI) were assessed before and immediately after the intervention, as were physical performance, estimated by gait speed (timed up-and-go test), and handgrip strength. Statistically significant improvements (p < 0.05) were observed both within and between groups for handgrip strength (Cohen's d = 0.40 and 0.52 respectively) and gait speed (Cohen's d = 0.86 and 0.87 respectively). After 12 weeks, BMI significantly decreased (Cohen's d = 0.07) only in the Pilates group. No significant differences were observed regarding SMI. In conclusion, a 12-week Pilates exercise intervention on community dwelling women over 60 years old shows beneficial effects on muscle strength, physical performance, and BMI, but failed to induce any changes on body composition.

Release Mode Dynamically Regulates the RRP Refilling Mechanism at Individual Hippocampal Synapses
Authors: Kim Yujin , Lee Unghwi , Choi Chunghon , Chang Sunghoe 
Published: September 2020

Synaptic strength and reliability are determined by the number of vesicles released per action potential and the availability of release-competent vesicles in the readily releasable pool (RRP). Compared with release of a single vesicle (univesicular release), multivesicular release (MVR) would speed up RRP depletion, yet whether the RRP is refilled differently during the two different release modes has not been investigated. Here, we address this question by quantitative optical imaging with an axon-targeting glutamate sensor, iGluSnFRpre. We found that hippocampal synapses preferentially release multiple vesicles per action potential at high extracellular calcium or by paired-pulse stimulation. When MVR prevails, the RRP is recovered very rapidly with a time constant of 430 ms. This rapid recovery is mediated by dynamin-dependent endocytosis followed by direct reuse of retrieved vesicles. Furthermore, our simulation proved that the portion of retrieved vesicles that directly refill the RRP increases dramatically (>70%) in MVR compared with that in univesicular release (<10%). These results suggest that the contribution of rapid and direct recruitment of retrieved vesicle to the RRP changes dynamically with release mode at the level of individual synapses, which suggests a form of presynaptic homeostatic plasticity for reliable synaptic transmission during various synaptic activity.SIGNIFICANCE STATEMENTThe number of vesicles released in response to an action potential and the number of release competent vesicles in the readily releasable pool (RRP) are the fundamental determinants of synaptic efficacy. Despite its functional advantages, releasing multiple vesicles, especially at small synapses, can deplete the RRP after a couple of action potentials. To prevent failure of synaptic transmission, the RRP should be refilled rapidly, yet whether the RRP replenishment process is regulated by the release mode has not been investigated. Here, using quantitative optical glutamate imaging and simulation, we demonstrate that the contribution of the fast refilling mechanism changes with release mode at the level of individual synapses, suggesting a rapid form of presynaptic homeostatic plasticity during various synaptic activity.
