Muonic-Atom Spectroscopy and Impact on Nuclear Structure and Precision QED Theory

open access: yes, 2022
Recent progress in laser and x-ray spectroscopy of muonic atoms offers promising long-term possibilities at the intersection of atomic, nuclear and particle physics. In muonic hydrogen, laser spectroscopy measurements will determine the ground-state hyperfine splitting (HFS) and additionally improve the Lamb shift by a factor of 5.

Quantum Protocol Architectures and Secure Control Frameworks For 7G+ Networks: Standards, Synchronization, Use Cases, and Challenges

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 5, May 2026.
ABSTRACT Quantum‐native communication systems are reshaping secure, programmable, and coherence‐aware networking beyond the classical paradigm. As intelligent physical infrastructures, ranging from unmanned aerial vehicle swarms to satellite Quantum Key Distribution (QKD) platforms, demand trust, synchronization, and ultra‐reliability, conventional ...

Parity violation in Møller scattering within low-energy effective field theory

open access: yesJournal of High Energy Physics
We include electroweak effects in Møller scattering at low energies in an effective field theory approach and compute the left-right parity-violating asymmetry.

A Customised, Intensive Parent–Child Interaction Therapy for Children With Down Syndrome: Findings From a Real‐World Pilot Effectiveness Study

open access: yesInternational Journal of Language &Communication Disorders, Volume 61, Issue 3, May/June 2026.
ABSTRACT Background Coaching parents through parent–child interaction therapy (PCIT) is a key aspect of early communication intervention for children with Down syndrome. However, the evidence for its effect on child language outcomes is limited. Some research has indicated that more intensive, individualised interventions yield better outcomes; however,

An explanation for the muon and electron g − 2 anomalies and dark matter

open access: yesJournal of High Energy Physics, 2020
We propose simple models with a flavor-dependent global U(1)ℓ and a discrete ℤ2 symmetries to explain the anomalies in the measured anomalous magnetic dipole moments of muon and electron, (g − 2) μ,e , while simultaneously accommodating a dark matter ...

Quark and gluon contents of a lepton at high energies

open access: yesJournal of High Energy Physics, 2022
In high-energy leptonic collisions, such as at a multi-TeV muon collider, the collinear splittings of the electroweak (EW) gauge bosons and leptons are the dominant phenomena, and the scattering processes should thus be formulated in terms of the EW ...

Real World Outcomes With Chemotherapy and Immunotherapy in Metastatic Poorly Differentiated Gastroenteropancreatic Neuroendocrine Carcinomas

open access: yesCancer Medicine, Volume 15, Issue 4, April 2026.
NCDB analysis showing potential benefit of immunotherapy alongside chemotherapy in metastatic GEP‐NECs. ABSTRACT Background Gastroenteropancreatic poorly differentiated neuroendocrine carcinomas (GEP‐NECs) are aggressive cancers where cytotoxic chemotherapy is the backbone of treatment.

Precision study of positronium and precision tests of the bound state QED

open access: yes, 2002
Despite its very short lifetime positronium provides us with a number of accurate tests of the bound state QED. In this note a brief overview of QED theory and precision experiments on the spectrum and annihilation decay of the positronium atom is presented. Special attention is paid to the accuracy of theoretical predictions.

Hadronic corrections to μ-e scattering at NNLO with space-like data

open access: yesJournal of High Energy Physics, 2019
The Standard Model prediction for μ-e scattering at Next-to-Next-to-Leading Order (NNLO) contains non-perturbative QCD contributions given by diagrams with a hadronic vacuum polarization insertion in the photon propagator.

Bioactivity Profiling of Coronarin A and Villosin Isolated From Hedychium coronarium J. Koenig: Acaricidal, Nematicidal, and Antifungal Potential

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
The graphical abstract illustrates the flowchart for the isolation and evaluation of bioactive compounds from Hedychium coronarium. Crude extracts were obtained via cold percolation from the aerial parts (flowers, leaves, and stems) using dichloromethane (DCM) and from the rhizomes using chloroform.
