The JTAG (Joint Test Action Group) protocol is a popular method to program FPGA (Field Programmable Gate Array) devices where more intelligent technology not applicable. However, the original designed for short distance connection and necessarily suitable when device located in remote radiation area. We developed custom optical transmission technique protocol. A small receiver test board based on discrete devices, multi-port distributor implemented an board. also overcome latency due...
We report new measurements of the decays B+-->rho+gamma, B0-->rho0gamma, and B0-->omegagamma using a data sample 657x10(6) B meson pairs accumulated with Belle detector at KEKB e+e- collider. measure branching fractions B(B+-->rho+gamma)=(8.7_-2.7-1.1;+2.9+0.9)x10(-7), B(B0-->rho0gamma)=(7.8_-1.6-1.0;+1.7+0.9)x10(-7), B(B0-->omegagamma)=(4.0_-1.7;+1.9+/-1.3)x10(-7). also isospin asymmetry Delta(rhogamma)=-0.48_-0.19-0.09;+0.21+0.08 first measurement direct CP-violating...
We report a measurement of the time-integrated $CP$ asymmetry in neutral charm meson decay $D^0 \to K^0_S K^0_S$ using 921~fb$^{-1}$ data collected at $Υ(4S)$ and $Υ(5S)$ resonances with Belle detector KEKB asymmetric-energy $e^+e^-$ collider. The observed is $$ A_{CP}(D^0 K^0_S) = (-0.02 \pm 1.53 0.17) \%, where first uncertainty statistical second systematic. This latter dominated by error normalisation channel. result consistent Standard Model expectations improves respect to previous...
We have developed readout electronics for the central drift chamber (CDC) of Belle-II detector. The space near endplate CDC installation was limited by detector structure. Due to large amounts data generated CDC, a high-speed link, with greater than one gigabit transfer rate, required back-end computer. A new module satisfy these requirements. This processes 48 signals from converts them digital and transfers it directly All functions that via high speed link were implemented on single...
The Central Drift Chamber (CDC) is the main device for tracking and identification of charged particles Belle-II experiment.

We present an extraction of azimuthal correlations between two pairs charged pions detected in opposite jets from electron-positron annihilation. These may arise the dependence di-pion fragmentation on polarization parent quark process $e^+e^- \rightarrow q \bar{q}$. Due to correlation polarizations, cross-section pair production, which pion are a dijet event, exhibits modulation angles planes containing hadron with respect production plane. The measurement this allows access combinations...

Vogt–Koyanagi–Harada disease (VKH) is an autoimmune disease, and glucocorticoid therapy (GC) widely used for VKH. We provided a profile of leukocyte populations serum cytokines in VKH patients under GC. A prospective observational study was conducted on three treatment-naïve patients. Peripheral blood samples were collected from the before GC (VKH-acute) after 6 months (VKH-remission), healthy individuals as controls. Proportions 37-type leukocytes levels 27-kind measured by mass cytometry...
