In this study 130 honeybee colonies in 4 locations (Damavand, Tehran, Qum and Karaj-Savojbolagh) were sampled to determine the phenotypic correlations among 9 morphological and 3 production traits. The morphological traits were length (FL) and width (FB) of fore wing, cubital index (CI), length of hind leg (HL), length of probosics (LP), slender index (SI), length (WL) and width (WT) of wax mir...

Single-nucleon knockout reaction studies of the proton-dripline nuclei $^{9}\mathrm{C}$ and $^{13}\mathrm{O}$ suggest an appreciable suppression spectroscopic factors. In this work, we calculate one-neutron one-proton factors for mirror pair $^{9}\mathrm{C}\text{\ensuremath{-}}^{9}\mathrm{Li}$ using two variants continuum shell model: complex-energy Gamow model real-energy embedded in continuum...

We present new experimental measurements of resonance strengths in the astrophysical 23Al(p,γ)24Si reaction, constraining pathway nucleosynthesis beyond 22Mg X-ray burster scenarios. Specifically, we have performed first measurement (d,p) reaction using a radioactive beam 23Ne to explore levels 24Ne, mirror analog 24Si. Four strong single-particle states were observed and corresponding neutron ...

At least five earlier studies could not find effector-dependent learning in the keying version of the serial reaction time (RT) task. Experiment 1 examined whether effector-dependent learning occurs when participants practice the serial RT task with three fingers of one hand for about 1,300 sequence repetitions instead of the more common 50-100 repetitions. The results confirm that, following e...

We have investigated the conformations of the hexadeoxyribonucleotide, L-d(CGCGCG) composed of L-deoxyribose, the mirror image molecule of natural D-deoxyribose. In this paper, we report the synthesis of four L-deoxynucleosides and the L-oligonucleotide-ethidium bromide interactions. The L-deoxyribose synthon 9 was synthesized from L-arabinose with an over all yield of 28.5% via the Barton-McCo...

The human mirror system has been the subject of much research over the past two decades, but little is known about the timecourse of mirror responses. In addition, it is unclear whether mirror and counter-mirror effects follow the same timecourse. We used single-pulse transcranial magnetic stimulation to investigate the timecourse of mirror and counter-mirror responses in the human brain. Exper...

Following Hawking, it is usual to mimic the effect of collapse space-time geometry on quantum fields in a semi-classical approximation by imposing suitable boundary conditions at the origin of coordinates, which effectively becomes a moving mirror. Suitable mirror trajectories induces a close analogue to the radiance of black holes, including a flux of outgoing radiation that appears accurately...
