Interference by Design: Embedding Moiré Beat‐Field Geometry into Variational Quantum Circuits for Brain Tumour Diagnosis

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 10, October 2026.
What if the key to efficient quantum diagnosis lies not in the circuit, but in the geometry feeding it? Embedding Moiré beat‐field interference into a variational quantum circuit sharpens brain tumour class boundaries, lifting four‐class MRI accuracy to 92.5% and halving circuit deptheach claim validated on real quantum hardware.

Functional renormalization group study of the quark-meson model with $$\omega $$ ω and $$\rho $$ ρ vector mesons

open access: yesEuropean Physical Journal C: Particles and Fields
We employ the functional renormalization group flow equations to investigate the phase structure of the two-flavor quark-meson model in the presence of a finite isospin chemical potential, incorporating interactions with omega and rho vector mesons.

Detection of magnetized quark-nuggets, a candidate for dark matter

open access: yesScientific Reports, 2017
Quark nuggets are theoretical objects composed of approximately equal numbers of up, down, and strange quarks and are also called strangelets and nuclearites.

Search for dark matter produced in association with a single top quark or a top quark pair in proton-proton collisions at s = 13 $$ \sqrt{s}=13 $$ TeV

open access: yesJournal of High Energy Physics, 2019
A search for dark matter produced in association with top quarks in proton-proton collisions at a center-of-mass energy of 13 TeV is presented. The data set used corresponds to an integrated luminosity of 35.9 fb−1 recorded with the CMS detector at the ...

Gamma ray bursts and the transition to quark matter in compact stars

open access: yes, 2006
We discuss a model for long Gamma-Ray-Bursts in which the central engine is associated with the conversion process of a metastable hadronic star into a star containing quark matter. We analyze the observational signatures of the model, i.e. the Supernova-

Effects of dietary nitrate supplementation on peak oxygen uptake following 10 days of Ramadan fasting in healthy adults

open access: yesExperimental Physiology, Volume 111, Issue 10, Page 4636-4645, 1 October 2026.
Abstract Ramadan is a sacred religious practice observed by Muslims that involves abstaining from food and water from sunrise to sunset for 1 month. Prior work has reported that peak oxygen uptake (V̇O2peak${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{peak}}}}$) can decline during Ramadan in parallel with reduced physical activity.

Acute and lifelong exercise modulate the tumorigenic potential of human lung cancer cells and their susceptibility to cisplatin

open access: yesExperimental Physiology, Volume 111, Issue 10, Page 4688-4704, 1 October 2026.
Abstract The association between higher levels of physical activity and lower cancer risk and mortality is well established. However, a causal link is yet to be proven. Recent studies showed a decrease in the proliferation rates of cultured human cancer cells when the human serum used to stimulate them was conditioned by acute exercise. Here, we tested

Measurement of the top quark charge in pp collisions at s√=7 TeV with the ATLAS detector [PDF]

open access: yes, 2013
A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb−1 of data at a centre-of-mass energy of 7 TeV. In units of the elementary electric charge, the top quark charge is determined

Clustered Quark Matter Calculation for Strange Quark Matter

open access: yes, 2009
Motivated by the need for a solid state strange quark matter to better explain some observational phenomena, we discussed possibility of color singlet cluster formation in cold strange quark matter by a rough calculation following the excluded volume method proposed by Clark et al (1986) and adopted quark mass density dependent model with cubic scaling.
