Ferromagnetism in two-dimensional hole-doped SnO

open access: yesAIP Advances, 2018
Hole-doped monolayer SnO has been recently predicted to be a ferromagnetic material, for a hole density typically above 5x1013/cm2. The possibility to induce a hole-doped stable ferromagnetic order in this two-dimensional material, either by intrinsic or

Voltage-controlled superconducting magnetic memory

open access: yesAIP Advances, 2019
Over the past few decades, superconducting circuits have been used to realize various novel electronic devices such as quantum bits, SQUIDs, parametric amplifiers, etc. One domain, however, where superconducting circuits fall short is information storage.

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 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.

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

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

The Combined Effect of Obesity and Contraceptive Use on Pulmonary Embolism in Adolescent Females Residing in the United States

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Combined oral contraceptive (COC) use in obese adult women dramatically increases the relative risk of developing a pulmonary embolism (PE). The risk of a PE in obese adolescent females taking contraceptives is currently unknown. The purpose of this investigation was to determine the effect of body mass index (BMI) and contraceptive
