The decay widths φ → γf0(980) and φ → γa0(980) are calculated taking into account the finite widths of the scalar resonances f0(980) and a0(980). The latter are shown to be essential in order to obtain meaningful results. Simultaneously we also study the decays φ → γππ and γπη where a good reproduction of the recent experimental data is obtained, pointing out the necessity of a φγKK̄ contact ver...

MicroRNAs have been associated with many different biological functions, but little is known about their roles in conditioned behavior. We demonstrate that Drosophila miR-980 is a memory suppressor gene functioning in multiple regions of the adult brain. Memory acquisition and stability were both increased by miR-980 inhibition. Whole cell recordings and functional imaging experiments indicated...

The crucial points of physics of light scalar mesons are discussed. The special attention is given to the chiral shielding of lightest scalar mesons and the production of the well established light scalar mesons in the φ radiative decays. Arguments in favor of the four-quark model of the a 0 (980) and f 0 (980) mesons are given. To discuss actually the nature of the putative nonet of the light ...
