Evaluation of pathways to the C-glycosyl isoflavone puerarin in roots of kudzu (Pueraria montana lobata)
Article describes how kudzu produces both O- and C-glycosylated isoflavones, with puerarin (C-glucosyl daidzein) as an important bioactive compound. The authors go on to explain how expression of recombinant UGTs in Escherichia coli and candidate C-glycosyltransferases in Medicago truncatula were used to explore substrate specificities, and gene silencing of UGT and key isoflavone biosynthetic genes in kudzu hairy roots employed to test hypotheses concerning the substrate(s) for C-glycosylation.

Descriptive Complexity in Cantor Series
Article discusses how a Cantor series expansion for a real number x with respect to a basic sequence Q=(q), where qi≥2, is a generalization of the base b expansion to an infinite sequence of bases. The authors show that for any basic sequence the set of distribution normal numbers is Π03-complete, and if Q is 1-divergent then the sets of normal and ratio normal numbers are Π03-complete.

Unravelling the Influence of Surface Modification on the Ultimate Performance of Carbon Fiber/Epoxy Composites
Article asserts that the overall performance of polymer composites depends on not only the intrinsic properties of the polymer matrix and inorganic filler but also the quality of interfacial adhesion. The authors report carbon fiber (CF)/epoxy composites with improved interfacial adhesion by covalent bonding between CFs and the epoxy matrix, which leads to the improved ultimate mechanical properties and enhanced thermal aging performance.

Structure and inference in Japanese right dislocation
Article exploring the syntactic nature of Japanese Right Dislocation Constructions (RDCs) by illuminating the ellipsis sites in the postverbal domains of the constructions via pragmatic inference. Although the most prevailing bi-clausal analysis of RDCs adopts the perspective that the repetition of the antecedent clause occurs in collocation, this paper shows that the same surface strings are potentially ambiguous since right dislocation is a heterogeneous phenomenon. It proposes additional types of a bi-clausal structure and discusses evidence that suggests that even when the surface strings are the same the recovery of the ellipsis site is possibly derived in multiple ways through the use of distinct linguistic strategies.
