Precision control of miniature SCARA robots for multi-object spectrographs

International Journal of Optomechatronics, 2020
Advances in astronomy led to the demand for measuring the spectra of multiple night sky objects simultaneously. Some of these Multi-Object Spectrographs use robotic systems that position optical fibers in the focal plane of the observing telescope. These

Contribution of the vector meson to the $\Upsilon \left(nS\right)\to {\overline{d}}^{*}\left(2380\right)+X$ decay channel

Physical Review, 2019
d*(2380) was observed by WASA-at-COSY collaborations in the nuclear reaction recently. Its particularly narrow width may indicate the new QCD-allowed hadronic structure. To further confirm the existence of this peculiar particle in a totally different kind of reaction, ϒ(nS)→d¯*(2380)+X, the contribution from the vector meson should also be considered.

E-model MOS Estimate Improvement through Jitter Buffer Packet Loss Modelling

Advances in Electrical and Electronic Engineering, 2011
Proposed article analyses dependence of MOS as a voice call quality (QoS) measure estimated through ITU-T E-model under real network conditions with jitter. In this paper, a method of jitter effect is proposed.

Multiple Transcoding Impact on Speech Quality in Ideal Network Conditions

Advances in Electrical and Electronic Engineering, 2015
This paper deals with the impact of transcoding on the speech quality. We have focused mainly on the transcoding between codecs without the negative influence of the network parameters such as packet loss and delay.

Resonant contributions to three-body $B_{\left(s\right)}\to [D^{(*)},{\overline{D}}^{(*)}]K^{+}{K}^{-}$ decays in the perturbative QCD approach

Physical Review, 2020
In this work, we study the S, P, and D wave resonance contributions to three-body decays B(s)→[D(*),D¯(*)]K+K− by employing the perturbative QCD (PQCD) approach, where the kaon-kaon invariant mass spectra are dominated by the f0(980), f0(1370), ϕ(1020), ϕ(1680), f2(1270), f2′(1525), f2(1750), and f2(1950) resonances.

Measurement of lepton universality parameters in $B^{+}\to K^{+}{\ell }^{+}{\ell }^{-}$ and $B^0\to K^{*0}{\ell }^{+}{\ell }^{-}$ decays

Physical Review, 2023
A simultaneous analysis of the B+→K+ℓ+ℓ− and B0→K*0ℓ+ℓ− decays is performed to test muon-electron universality in two ranges of the square of the dilepton invariant mass, q2. The measurement uses a sample of beauty meson decays produced in proton-proton collisions collected with the LHCb detector between 2011 and 2018, corresponding to an integrated ...

${\Lambda }_b\to {\Lambda }^{*}\left(1520\right){\ell }^{+}{\ell }^{-}$ form factors from lattice QCD

Physical Review, 2021
We present the first lattice QCD determination of the Λb→Λ*(1520) vector, axial vector, and tensor form factors that are relevant for the rare decays Λb→Λ*(1520)ℓ+ℓ−. The lattice calculation is performed in the Λ*(1520) rest frame with nonzero Λb momenta, and is limited to the high-q2 region. An interpolating field with covariant derivatives is used to
