Phase speed saturation of Farley‐Buneman waves due to stochastic, self‐induced fluctuations in the background flow
Authors: Rojas E. L. , Young M. A. , Hysell D. L. 
Published: May 2016

AbstractThe phase speed saturation of Farley–Buneman waves is studied as an interaction with the random turbulent fluctuations in the background. We used the formalism of stochastic differential equations to model the complex interactions with a linearized system plus a stochastic term. Applying an averaging technique, we can obtain an augmented linear system that depends on the random behavior of the waves. The results show that following this approach we can obtain phase velocities that saturate close to the ion acoustic speed (Cs). This approach seems promising for the study of the influence of plasma turbulence generated by different kinds of instabilities on the mean state of the ionosphere.
The role of bubbles during air‐sea gas exchange
Authors: Emerson Steven , Bushinsky Seth 
Published: May 2016

AbstractThe potential for using the air‐sea exchange rate of oxygen as a tracer for net community biological production in the ocean is greatly enhanced by recent accuracy improvements for in situ measurements of oxygen on unmanned platforms. A limiting factor for determining the exchange process is evaluating the air‐sea flux contributed by bubble processes produced by breaking waves, particularly during winter months under high winds. Highly accurate measurements of noble gases (Ne, Ar & Kr) and nitrogen, N2, in seawater are tracers of the importance of bubble process in the surface mixed layer. We use measured distributions of these gases in the ventilated thermocline of the North Pacific and an annual time series of N2 in the surface ocean of the NE Subarctic Pacific to evaluate four different air‐water exchange models chosen to represent the range of model interpretation of bubble processes. We find that models must have an explicit bubble mechanism to reproduce concentrations of insoluble atmospheric gases, but there are periods when they all depart from observations. The recent model of Liang et al. (2013) stems from a highly resolved model of bubble plumes and categorizes bubble mechanisms into those that are small enough to collapse and larger ones that exchange gases before they resurface, both of which are necessary to explain the data.
Synthesis of Benzofurans from Ketones and 1,4‐Benzoquinones
Authors: Wu Fengtian , Bai Rongxian , Gu Yanlong 
Published: May 2016

AbstractBenzofuran derivatives can be synthesized through the sequential Michael addition and cyclization of 1,3‐dicarbonyl compounds with 1,4‐benzoquinones. However, ketones are rarely used in this reaction because of their low nucleophilicities. In this study, this problem was solved by utilizing triethyl orthoformate, which enabled the formation of a vinyl ethyl ether as an additive. As a result, the nucleophilicity of ketones increased. Many important 5‐hydroxybenzofuran derivatives, which were not readily available by synthesis in the past, were also prepared via these newly established reactions.magnified image
Plasma metabolomic profile and potential biomarkers for missed abortion
Authors: Fei He , Hou Jiebin , Wu Zhenghong , Zhang Liwen , Zhao Hongxia , Dong Xin , Chen Yaping 
Published: May 2016

AbstractA missed abortion (MA) is an in utero death of the embryo or fetus before the 20th week of gestation with retained products of conception, and this condition is currently common in China. In order to discover novel biomarkers for MA, ultrahigh performance liquid chromatography was applied to study plasma metabolite profiles for 33 patients with MA and 29 control subjects. Thirty‐seven differential plasma metabolites were found to discriminate between the two groups in the initial cohort (15 subjects with MA and 15 healthy controls). The feasibility of using these potential biomarkers to predict MA was further evaluated in the validation cohort (18 subjects with MA and 14 healthy controls) and 15 had an area under the receiver operating characteristic curve of >0.80, making them satisfactory. Tryptophan metabolism and sphingolipid metabolism were identified as important potential target pathways for MA using metabolic pathway impact analysis. Furthermore, three of the 15 satisfactory metabolites (glyceric acid, indole and sphingosine) were combined to establish a predictive model with 100% sensitivity and 100% specificity in the validation cohort. Taken together, these results suggest that MA results in significant disturbance of metabolism and those various novel biomarkers have satisfactory diagnostic and predictive power for MA.
Aniline‐Promoted Cyclization–Replacement Cascade Reactions of 2‐Hydroxycinnamaldehydes with Various Carbonic Nucleophiles through In Situ Formed N,O‐Acetals
Authors: Yu Chenguang , Huang He , Li Xiangmin , Zhang Yueteng , Li Hao , Wang Wei 
Published: May 2016

AbstractIn this study, we report the harnessing of new reactivity of N,O‐acetals in an aminocatalytic fashion for organic synthesis. Unlike widely used strategies requiring the use of acids and/or elevated temperatures, direct replacement of the amine component of the N,O‐acetals by carbon‐centered nucleophiles for C−C bond formation is realized under mild reaction conditions. Furthermore, without necessary preformation of the N,O‐acetals, an amine‐catalyzed in situ formation of N,O‐acetals is developed. Coupling both reactions into a one‐pot operation enables the achievement of a catalytic process. We demonstrate the employment of simple anilines as promoters for the cyclization–substitution cascade reactions of trans‐2‐hydroxycinnamaldehydes with various carbonic nucleophiles including indoles, pyrroles, naphthols, phenols, and silyl enol ethers. The process offers an alternative approach to structurally diverse, “privileged” 2‐substituted 2H‐chromenes. The synthetic power of the new process is furthermore shown by its application in a 2‐step synthesis of the natural product candenatenin E and for the facile installation of 2‐substituted 2H‐chromene moieties into biologically active indoles.
