As part of a study of the factors controUingeye facet number in Drosophila melanogaster, selection has been carried on with a view to the determination of the germinal changes appearing during the course of selection. One of the most interesting of these changes occurred during the second generation of downward selection in the white bar stock. An exceptionally "low" male of this generation was...

We measure the branching fractions and $CP$ asymmetries for decays $B^{0}\to \bar{D}^{0}\pi^{0}$ $B^{+}\to \bar{D}^{0}\pi^{+}$, using a data sample of $772\times 10^{6}$ $B\bar{B}$ pairs collected at $\Upsilon(4S)$ resonance with Belle detector KEKB $e^{+}e^{-}$ collider. The obtained direct are $\mathcal{B}(B^{0}\to \bar{D}^{0}\pi^{0}) = [2.70 \pm 0.06~ \text{(stat.)} 0.10~ \text{(syst.)}] \ti...

Abstract The full-heavy tetraquarks $$cc{\bar{c}}{\bar{b}}$$ c ¯ b and $$bb{\bar{b}}{\bar{c}}$$ are systematically investigated within a quark model. meson–meson structure, diquark–antidiquark structure K-structure considered in...

Assuming independence between failure modes makes system reliability calculation simple but it adds approximation error. Interestingly, error due to ignoring dependence can be negligible for a highly reliable system. This paper investigates the reasons and the factors affecting the error. Error in system probability of failure (PF) is small for high reliability when tail-dependence is not very ...

Abstract We study the CP violation in two-body nonleptonic decays of $$B_c$$ B c meson. concentrate on decay channels which contain at least one excited heavy meson final states. Specifically, following are considered: $$B_c\rightarrow c{\bar{c}}(2S, 2P)+{\bar{c}}q(1S, ...

Standard maize starch was hydrothermally treated by Instantaneous Controlled Pressure Drop (DIC) process at three pressure levels (1, 2 and 3 bar) corresponding to the temperatures of 100, 122 and 135 °C (at 13–27% moisture), respectively. The structural effects of various hydrothermal conditions were examined with differential scanning calorimetry (DSC) and wide-angle X-ray diffraction. In ord...

We report the structure, performance and large-area fabrication of a thin plasmonic infrared absorber, termed "bar-shaped disk-coupled dots-on-pillar antenna-array" (bar-D2PA). The bar-D2PAs, which are simple to fabricate, demonstrate the following, experimentally: (i) a different light-absorption resonance for each polarization with the resonance peak tunable by the bar-to-backplane gap and th...

In this paper, a piezoelectrically actuated four-bar mechanism with two flexible links is proposed to be used in a micromechanical flying insect robot wing thorax for stroke amplification. PZT-5H and PZN-PT based unimorph actuators are utilized at the input link of the four-bar for a compact and light weight thorax transmission mechanism. The kinematics and dynamics of the proposed wing structu...

We discuss different aspects of nested bar systems, both observational and theoretical. Such systems consist of a large-scale primary bar leading to the formation of a sub-kpc size secondary bar, whose pattern speed differs substantially from that of the main bar. Specifically, we focus on the origin and gravitational decoupling of nested bars, and their characteristic gas flows on scales of ∼ ...
