The relationship between misophonia, stress, and traumatic stress has not been well characterized scientifically. This study aimed to explore the relationships among misophonia, stress, lifetime traumatic events, and traumatic stress. A community sample of adults with self-reported misophonia (N = 143) completed structured diagnostic interviews and psychometrically validated self-report measures. Significant positive correlations were observed among perceived stress, traumatic stress, and misophonia severity. However, multivariate analyses revealed that perceived stress significantly predicted misophonia severity, over and above traumatic stress symptoms. The number of adverse life events was not associated with misophonia severity. Among symptom clusters of post-traumatic stress disorder, only hyperarousal was associated with misophonia severity. These findings suggest that transdiagnostic processes related to stress, such as perceived stress and hyperarousal, may be important phenotypic features and possible treatment targets for adults with misophonia.

The asymptotic method has been used to investigate the columnar crystals growth subjected to far-field flow in ternary undercooled melt under non-isothermal conditions, and approximate analytical expression of radius and interface growth rate of columnar crystals growth have been given. It is found that the flow causes columnar crystal to grow faster in the upstream direction and slower in the downstream direction, and the growth of columnar crystals in flowing ternary melt is also affected by impurity content, that is, the higher the impurity content, the faster the columnar crystal grows in the upstream direction and the slower the growth in the downstream direction. The growth problem of columnar crystals from multi-component melt under flow is more complicated than that of a pure melt because it involves both the heat transport process and mass transport in the solute. The results show that the deflection angle of columnar crystals is a result of interaction of flow and impurity content. [ABSTRACT FROM AUTHOR]

Abstract: Two new salicylaldehyde Schiff base chemosensors have been synthesized. Their crystal structures, photophysical properties as well as recognition properties for Cu2+ ions have also been examined. Their absorption peaks exhibit obvious blue shift upon the addition of Cu2+ to a HEPES buffer–methanol (3:7, v/v) solution of the compounds. The compounds are found to be able to recognize Cu2+ ions with fluorescence turn-on response in aqueous solution owing to the hydrolysis of the hydrazone bond in the Schiff׳s base compounds induced by Cu2+ ions.

Abstract: The optimizations geometries and interaction energies corrected by BSSE of the complexes between C4H4Y (Y=O, S) and BX3 (X=H, F, Cl) have been calculated at the B3LYP/6-311++G(d,p) and MP2/6-311++G(d,p) levels. Six conformers are obtained. Conformers (a) and (d), with calculated binding energies, −32.57 and −21.01kJmol−1 (MP2), respectively, are the most stable ones. The charge transfers, which are related to the combination energies, take place through the whole complexes formation. The analyses for the combining interaction between BX3 and furan homologues with the atom-in-molecules theory (AIM) and natural bond orbital method (NBO) have been performed. [Copyright &y& Elsevier]
