Laser Method for Studying Temperature Distribution within Yb:YAG Active Elements

open access: yesPhotonics, 2022
Currently, laser systems based on active elements doped with Yb3+ with simultaneously high pulse repetition rates and high peak power are in demand for many applications.

Observation of and evidence for decays

open access: yesNew Journal of Physics, 2014
Measurements of the branching fractions of $B_{s}^{0}\to {{K}^{*\pm }}{{K}^{\mp }}$ and $B_{s}^{0}\to {{K}^{*\pm }}{{\pi }^{\mp }}$ decays are performed using a data sample corresponding to $1.0\ {\rm f}{{{\rm b}}^{-1}}$ of proton-proton collision data ...

The Spectral X-ray Imaging Data Acquisition (SpeXIDAQ) Framework

open access: yesSensors, 2021
Photon counting X-ray imagers have found their way into the mainstream scientific community in recent years, and have become important components in many scientific setups. These camera systems are in active development, with output data rates increasing

The mechanism of the global vertical force reduction in disruptions mitigated by massive material injection

open access: yesNuclear Fusion, 2023
Disruptions lead to a rapid loss of thermal and magnetic energy and can cause large heat loads, mechanical forces, and the excitation of a beam of relativistic runaway electrons.

First-principles study of tunable anisotropy in silicon superlattices for directionally selective channels [PDF]

open access: yesAIP Advances
We use first-principles electronic-structure and lattice-dynamics calculations to identify dynamically stable configurations of silicon-compatible superlattices with Si/O or Si/Ge monolayers and Si/2Ge bilayers that provide a materials-level handle for ...

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

Search for B s 0 $$ {\textrm{B}}_{\textrm{s}}^0 $$ → ℓ ∓ τ ± with the semi-leptonic tagging method at Belle

open access: yesJournal of High Energy Physics, 2023
We present a search for the lepton-flavor-violating decays B s 0 $$ {B}_s^0 $$ → ℓ ∓ τ ± , where ℓ = e, μ, using the full data sample of 121 fb −1 collected at the Υ(5S) resonance with the Belle detector at the KEKB asymmetric-energy e + e − collider. We

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Constraining new physics in b → cℓν transitions

open access: yesJournal of High Energy Physics, 2019
B decays proceeding via b → cℓν transitions with ℓ = e or μ are tree-level processes in the Standard Model. They are used to measure the CKM element V cb , as such forming an important ingredient in the determination of e.g. the unitarity triangle; hence

Impact of Radiation Therapy on Physical and Psychosocial Health of Adolescents and Young Adults: A Joint Report From the Children's Oncology Group AYA and Radiation Oncology Committees

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.
