Crossing two parental plants carrying two types of extra chromosomes, 2n+2(5L*7S) by 2n+3(2S*2S) permitted effective selection for individuals with up to eight 2S*2S chromosomes in later generations. The crossing of 2n + 3(2S*2S) by 2n+1( 8S*8L) and by the wild tomato relative, diploid L. pimpinellifolium , produced plants with up to four extra chromosomes. The tolerance of 2S*2S chromosomes th...
Measurement of ψ(2S) meson production in pp collisions at √ s = 7 TeV Abstract The differential cross-section for the inclusive production of ψ(2S) mesons in pp collisions at √ s = 7 TeV has been measured with the LHCb detector. The data sample corresponds to an integrated luminosity of 36 pb −1. The ψ(2S) mesons are reconstructed in the decay channels ψ(2S) → μ + μ − and ψ(2S) → J /ψπ + π − , ...
First observations of the Bs → ψ(2S)η, B0 → ψ(2S)π+π− and Bs → ψ(2S)π+π− decays are made using a dataset corresponding to an integrated luminosity of 1.0 fb−1 collected by the LHCb experiment in proton–proton collisions at a centre-of-mass energy of √ s = 7 TeV. The ratios of the branching fractions of each of the ψ(2S) modes with respect to the corresponding J/ψ decays are B(Bs →ψ(2S)η) B(Bs →...
Caspase-2 (casp-2) is the most conserved caspase across species, and is one of the initiator caspases activated by various stimuli. The casp-2 gene produces several alternative splicing isoforms. It is believed that the long isoform, casp-2L, promotes apoptosis, whereas the short isoform, casp-2S, inhibits apoptosis. The actual effect of casp-2S on apoptosis is still controversial, however, and...
We consider the partition function of the boundary OSp(2S + 2|2S) coset sigma model on an annulus, based on the lattice regularization introduced in the companion paper. Using results for the action of OSp(2S+2|2S) and BL(2) on the corresponding spin chain, as well as mini-superspace and small g σ calculations, we conjecture the full spectrum and set of degeneracies on the entire critical line....
Color-suppressed decays of B mesons to final states with ψ(2S) mesons have been observed with the CLEO detector. The branching fractions for the decays B+ → ψ(2S)K+, B+ → ψ(2S)K∗(892)+, B0 → ψ(2S)K0, and B0 → ψ(2S)K∗(892)0 are measured to be (7.8±0.7±0.9)×10−4 , (9.2±1.9± 1.2)× 10−4, (5.0± 1.1± 0.6)× 10−4, and (7.6± 1.1± 1.0)× 10−4, respectively, where the first uncertainty is statistical and t...
Transport collision integrals of interacting atoms or ions are essential in modeling transport properties high-temperature gases and plasmas. Here, we obtained the potential energy curves (PECs) CH using state-of-the-art ab initio methods. The PECs were also extrapolated to investigate for C(3P)-H(2S), C(5S)-H(2S), C(1S)-H(2S), C(1D)-H(2S) interactions, which interactions between excited C(5S),...
Of 4-amino-5-chloro-2-methoxy-N-(1-ethyl-2-hydroxymethyl-4- pyrrolidinyl)benzamide, four optical isomers, (2S,4S)-1 (TKS159), (2S,4R)-25, (2R,4S)-26 and (2R,4R)-27, were prepared from optically active 4-amino-1-ethyl-2-hydroxymethylpyrrolidine di-p-toluenesulfonate [(2S,4S)-14, (2S,4R)-17, (2R,4S)-20 and (2R,4R)-23, respectively]. The requisites, (2S,4S)-14, (2S,4R)-17, (2R,4S)-20 and (2R,4R)-2...
