Reconstructing a light pseudoscalar in the Type-X two Higgs doublet model
Physics Letters B, 2017 We investigate the detectability as well as reconstructibility of a light pseudoscalar particle A, of mass in the 50–60 GeV range, which is still allowed in a Type-X (lepton-specific) two-Higgs doublet scenario.

Fundamentals of Non-relativistic Collisionless Shock Physics: V. Acceleration of Charged Particles [PDF]
arXiv, 2008 A comprehensive review is given of the various processes proposed for accelerating particles by shocks to high energies. These energies are limited by several bounds: the non-relativistic nature of the heliospheric collisionless shocks to which this review restricts, the finite size of these shocks, the finite width of the downstream region, and to the

Particle Acceleration Mechanisms [PDF]
, 2017 This chapter provides a short tutorial review on particle acceleration in dynamic electromagnetic fields under scenarios relevant to the problem of particle acceleration in the solar corona and solar wind during solar eruptions. It concentrates on fundamental aspects of the acceleration process and refrains from presenting detailed modeling of the ...

Advanced Biology, EarlyView.In this study, a new type of bioactive glass fiber ‐based composite magnesium phosphate bone cement is prepared and verified that its mechanical strength and biological properties. In addition, the cement may have played a biologically active role in the Notch and HIF signaling pathways.

Superconductivity in particle accelerators
, 2023 This text is a full transcription of a lecture was given in the Joint Universities Accelerator School (JUAS) in 2023. A much shorter version is to be published in the JUAS book in 2024, along with all other lectures from the JUAS school. The aim of this lecture is to provide to physicists non-expert in materials science a glimpse on how superconducting

Advanced Engineering Materials, EarlyView.AISI 304L stainless steel powder is mixed with silicon nitride (Si3N4) powder and processed by PBF‐LB/M, allowing partial retention of Si3N4. The numerical approach effectively predicts the Si3N4 powder homogeneity and N content distribution on the powder bed. Recent studies have focused on the alloying of nitrogen (N) in high‐alloy stainless steels by

Entanglement of Uniformly Accelerating Schrodinger, Dirac, and Scalar Particles [PDF]
arXiv, 2007 We study how the entanglement of an entangled pair of particles is affected when one or both of the pair is uniformly accelerated, while the detector remains in an inertial frame. We find that the entanglement is unchanged if all degrees of freedom are considered.
arxiv
, 2016 One of the most severe limitations in high-intensity particle colliders is the beam-beam interaction, i.e. the perturbation of the beams as they cross the opposing beams.

Hydrogel‐Based Capacitive Sensor Model for Ammonium Monitoring in Aquaculture
Advanced Engineering Materials, EarlyView.Traditional techniques for monitoring aquaculture water quality, particularly ammonium levels, harm fish. This work presents a novel capacitive sensor with an ionic hydrogel transducer to monitor ammonium concentration in real time based on the ammonium‐induced hydrogel dissociation and osmotic pressure. Monitoring aquaculture water quality, especially

Monte Carlo studies of quantum cosmology by the generalized Lefschetz thimble method
Journal of High Energy PhysicsQuantum cosmology aims at elucidating the beginning of our Universe. Back in early 80’s, Vilenkin and Hartle-Hawking put forward the “tunneling from nothing” and “no boundary” proposals.
