  • One new phenylpropanoid glucoside (3), along with one known phenylpropanoid (1), and one known alkyl glucoside (2) were isolated from the fruits of Illicium verum and their chemical structures were elucidated on the basis of spectroscopic studies.

  • The current study examined 3- and 4-year-olds' affective decision-making in a variety of cultural contexts by comparing European Canadian children to Chinese Canadian, Hong Kong Chinese, and mainland Chinese children (N = 245). All children were tested with a delay of gratification task in which children chose between an immediate reward of lower value and a delayed reward of higher value. Results showed that Chinese Canadian and Hong Kong Chinese children chose more delayed rewards than European Canadian children, with mainland Chinese children showing a trend toward more delayed rewards. Across cultures, 4-year-olds chose more delayed rewards than 3-year-olds; and among 4-year-olds, girls made more such choices than boys. The findings are consistent with previous findings that exposure to Chinese culture is associated with better cool executive function, but they also highlight the importance of examining development across diverse cultural contexts.

  • Recently, Li [12] gave an asymptotic formula for the ultimate ruin probability in a delayed-claim risk model with constant force of interest and pairwise quasi-asymptotically independent and extended-regularly-varying-tailed claims. This paper extends Li's result to the case in which the risk model is perturbed by diffusion, the claims are consistently-varying-tailed and the main-claim interarrival times are widely lower orthant dependent.

  • Five compounds of iridoids, lignan and phenylpropanoid glycosides were isolated from the roots of Valeriana jatamansi by column chromatography. Their structures were elucidated as 11-methoxyviburtinal (1), baldrinal (2), prinsepiol-4-O-${\beta}$-D-glucoside (3), coniferin (4), and hexacosanic acid (5) by spectroscopic analysis. 11-Methoxyviburtinal was a new compound, and others were isolated from the plant for the first time.

  • Since designing a feedback topology is a practical way to implement interference alignment at reduced cost of channel state information (CSI) feedback, six feedback topologies have been presented in prior works for a K-user multiple-input multiple-output interference channel. To fully reveal the potential benefits of the feedback topology in terms of the saving of CSI overhead, we propose a new feedback topology in this paper. By efficiently performing dimensionality-decreasing at the transmitter side and aligning interference signals at a subset of receivers, we show that the proposed feedback topology obtains substantial reduction of feedback cost over the existing six feedback designs under the same antenna configuration.
