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.

Substrate screening effects on the quasiparticle band gap and defect charge transition levels in MoS$_2$

, 2018
Monolayer MoS$_2$ has emerged as an interesting material for nanoelectronic and optoelectronic devices. The effect of substrate screening and defects on the electronic structure of MoS$_2$ are important considerations in the design of such devices. Here,

Multimodal treatment for local recurrent malignant gliomas: resurgery and/or reirradiation followed by chemotherapy [PDF]

, 2019
The therapeutic management of recurrent malignant gliomas (MGs) is not determined. Therefore, the efficacy of a multimodal approach and a combination systemic therapy was investigated.

Enhanced $B_q\to \ell {\ell }^{\prime }$ and $B\to (K,\pi )\ell {\ell }^{\prime }$ in light of $(g-2{)}_{\mu }$

Physical Review, 2023
We study lepton flavor violating (LFV) B decays in a general two Higgs doublet model with sub-TeV exotic scalars. Two different parameter spaces are explored: one dominated by extra top Yukawa coupling ρtt, the other by LFV couplings relevant for the muon g−2 anomaly. In the first case, flavor constraints such as ℓ→ℓ′γ, h→ℓℓ′ imply LFV B decays are far

Communication and Language Profiles of Children Treated for Posterior Fossa Brain Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cognitive and language deficits are frequently reported sequelae of posterior fossa brain tumors (PFBT). Typically, delayed onset impedes prompt assessment and early intervention. This has devastating implications for quality of life.

${\Lambda }_b\to {\Lambda }^{*}\left(1520\right){\ell }^{+}{\ell }^{-}$ 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

The HIT Network for Children and Adolescents With CNS Tumors Facilitates Improvements of Diagnostic Assessments, Multimodal Treatments, Individual Counseling, and Research in Germany, Austria, and Switzerland

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The HIT network was established in 2000 to create a population‐based structure aiming to improve survival rates and reduce late effects for children with central nervous system (CNS) tumors by conducting comprehensive clinical trials.

Cost-Effectiveness of Lifestyle-Related Interventions for the Primary Prevention of Breast Cancer: A Rapid Review

Frontiers in Medicine, 2020
Background: In 2018, the global estimate of newly diagnosed breast cancer cases among women totaled 2.1 million. The economic and social burden that breast cancer places on societies has propelled research that analyzes the role of modifiable risk ...

Characterization of the second- and third-order nonlinear optical susceptibilities of monolayer MoS$_2$ using multiphoton microscopy

, 2016
We report second- and third-harmonic generation in monolayer MoS$_\mathrm{2}$ as a tool for imaging and accurately characterizing the material's nonlinear optical properties under 1560 nm excitation.

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.
