Approximate Ricci‐Flat Metrics for Calabi–Yau Manifolds
Fortschritte der Physik, Volume 74, Issue 7, July 2026.ABSTRACT We outline a method to determine analytic Kähler potentials with associated approximately Ricci‐flat Kähler metrics on Calabi–Yau manifolds. Key ingredients are numerically calculating Ricci‐flat Kähler potentials via machine learning techniques and fitting the numerical results to Donaldson's ansatz.

Diquark condensation effects on hot quark star configurations [PDF]
, 2006 The equation of state for quark matter is derived for a nonlocal, chiral quark model within the mean field approximation. We investigate the effects of a variation of the form-factors of the interaction on the phase diagram of quark matter.

Meissner effect and vortex dynamics in quark stars [PDF]
, 2004 We present a new model for soft gamma-ray repeaters based on a quark star born with temperatures above the critical value (Tc) for the onset of the colour-flavor locked superconductivity. The quark star then quickly cools below Tc, expelling a fraction

Neutron stars velocities and magnetic fields
EPJ Web of Conferences, 2018 We study a model that explain neutron stars velocities due to the anisotropic emission of neutrinos. Strong magnetic fields present in neutron stars are the source of the anisotropy in the system.

Respirology, Volume 31, Issue 7, Page 732-744, July 2026.We tested the respective effect of high‐flow and supplemental O2 from nasal high‐flow O2 therapy (NHFO2) on dyspnea and exercise tolerance in fibrotic interstitial lung disease. Supplemental O2 and NHFO2 (but not high‐flow) provided improvements in these outcomes at “iso‐O2 saturation” due to reduced ventilatory requirements.

RIGIDLY ROTATING STRANGE QUARK STARS
International Journal of Modern Physics D, 2005 In this article, we study rotating strange quark stars in the context of general relativity. For this purpose we consider perfect fluid model composed of strange quark matter with electromagnetic field in the Gödel Universe which has rigid rotation. We solve Einstein's field equations by using equation of state for strange quark matter.

Rotating Quark Stars in General Relativity
Universe, 2018 We have built quasi-equilibrium models for uniformly rotating quark stars in general relativity. The conformal flatness approximation is employed and the Compact Object CALculator (cocal) code is extended to treat rotating stars with surface density ...

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 7, July 2026.ABSTRACT Elite male football players have high peak fat oxidation (PFO), and recently PFO was reported to increase following preseason (PS) training in semi‐professional male players. Whether PFO increases from PS to competitive season (CS) in elite male football players remains unknown.

Upper limit on the mass of RX J1856.5–3754 as a possible quark star [PDF]
, 2003 Recent deep Chandra LETG+HRC-S observations suggest the possibility that RX J1856.5–3754 is a compact star whose radiation radius is 3.8–8.2 km. In this paper, we systematically calculate the mass-radius relations of quark stars within the bag model.

Impact of the Nuclear Equation of State on the Stability of Hybrid Neutron Stars
Universe, 2019 We construct a set of equations of state (EoS) of dense and hot matter with a 1st order phase transition from a hadronic system to a deconfined quark matter state. In this two-phase approach, hadrons are described using the relativistic mean field theory
