A dicentric chromosome is an abnormal chromosome with two centromeres on the same chromosome. It has been reported that dicentric chromosomes are specific biomarkers of radiation exposure, but dicentric chromosomes are rarely identified in newborns w

The development of 3d-metal-catalyzed β-C–H bond activation via 4-membered metallacycles remains an elusive challenge. Here, the authors report a Ni-Al bimetal-catalyzed β-C(sp3)–H bond activation of formamides via 4-membered nickelacycles.

Transition metal-catalyzed C−H cyclization for medium-ring synthesis has been limited to reactive C−H bonds, the activation of unreactive C−H bonds still remains a challenge. Here the authors show the direct construction of 7-membered rings via

Both bolting and flowering times influence taproot and seed production in radish. FLOWERING LOCUS C (FLC) plays a key role in plant flowering by functioning as a repressor. Two genomic DNA sequences, a 3 046-bp from an early- and a 2 959-bp from a la

Three-dimensional (3D) ultra-tiny Fe2O3 nanoparticles/graphene hydrogels were prepared using a facile and efficient solvothermal reaction, by which the phase of iron oxide, particle size and the morphology of hydrogels can be precisely controlled by

Conventional C–H alkenylation with alkynes via low-valent transition-metal catalysis occurs at the C6 or C4 position of 2-pyridone with electron-deficient C–H bonds. A bifunctional ligand-bonded Ni...

Previously reported direct C–H functionalization reactions of enamides mainly occurred at vinylic C(sp2)–H bonds because of their relatively high reactivity, while less reactive β′-C(sp3)–H activat...

The development of transition metal-catalyzed β-C−H bond activation via highly-strained 4-membered metallacycles has been a formidable task. So far, only scarce examples have been reported to undergo β-C−H bond activation via 4-membered metalla

A carbamoyl fluoride-enabled enantioselective Ni-catalyzed carbocarbamoylation of unactivated alkenes was developed, providing a broad range of chiral γ-lactams bearing an all-carbon quaternary center in 45-96% yield and 38-97% ee.

In this paper, we present a $q$-analogue of the polynomial reduction which was originally developed for hypergeometric terms. Using the $q$-Gosper representation, we describe the structure of rational functions that are summable when multiplied with
