Expression of the mouse miR-290-295 cluster and its miR-371-373 homolog in human is restricted to early embryos, primordial germ cells, the germ line stem cell compartment of the adult testis and to stem cell lines derived from the early embryonic lineages. Sequencing data suggest considerable seed diversification between the seven homologous pre-miRNAs of miR-290-295 but it is not clear if all...
We study the χc1 → ηπ+π− decay, paying attention to the production of f0(500), f0(980), and a0(980) from the final state interaction of pairs of mesons that can lead to these three mesons in the final state, which is implemented using the chiral unitary approach. Very clean and strong signals are obtained for the a0(980) excitation in the ηπ invariant mass distribution and for the f0(500) in th...
We report on the results of the first measurement of exclusive f_{0}(980) meson photoproduction on protons for E_{gamma}=3.0-3.8 GeV and -t=0.4-1.0 GeV2. Data were collected with the CLAS detector at the Thomas Jefferson National Accelerator Facility. The resonance was detected via its decay in the pi;{+}pi;{-} channel by performing a partial wave analysis of the reaction gammap-->ppi;{+}pi;{-}...
OBJECTIVE The purpose of this study was to compare the penetration of 808 and 980 nm laser light through bovine tissue samples 18-95 mm thick. BACKGROUND DATA Low-level laser therapy (LLLT) is frequently used to treat musculoskeletal pathologies. Some of the therapeutic targets are several centimeters deep. METHODS Laser light at 808 and 980 nm (1 W/cm(2)) was projected through bovine tissu...
The influence of wall thickness and specimen surface on the creep behavior single-crystal nickel-based superalloy MAR M247LC is studied. Specimens with thicknesses 0.4, 0.8, 1 2 mm, without casting surface, are compared to specimens same prepared from bulk material. Creep turned out be independent conditions even for thinnest specimens. debit effect not pronounced short rupture times (?100 h at...
We estimate the di-photon coupling of f0(600), f0(980) and f2(1270) resonances in a coupled channel dispersive approach. The f0(600) diphoton coupling is also reinvestigated using a single channel T matrix for ππ scattering with better analyticity property, and it is found to be significantly smaller than that of a q̄q state. Especially we also estimate the di-photon coupling of the third sheet ...
The coupled channel model of the a0(980) and a0(1450) resonances has been constructed using the separable πη and KK interactions. We have shown that two S–matrix poles corresponding to the a0(980) meson have significantly different widths in the complex energy plane. The KK to πη branching ratio, predicted in our model near the a0(1450) mass, is in agreement with the result of the Crystal Barre...
