Electromagnetic corrections to hadronic vacuum polarization contribute significantly to the uncertainty of the Standard Model prediction of the muon anomaly, which poses conceptual and numerical challenges for ab initio lattice determinations. In this study, we compute the non-singlet contribution from intermediate Euclidean current separations in quantum chromo- and electrodynamics (QCD+QED) using C$^{⋆}$ boundary conditions in two ways: either non-perturbatively by sampling the joint probability distribution directly or by perturbatively expanding from an isospin-symmetric theory [...]

Over the past decade, an abundance of information from neutron-star observations, nuclear experiments and theory has transformed our efforts to elucidate the properties of dense matter. However, at high densities relevant to the cores of neutron stars (NSs), substantial uncertainty about the dense matter equation of state (EoS) remains. [...]

The phenomenon of liquid metal embrittlement (LME) poses safety concerns for welded joints in themanufacturing field. In present study, LME was observed in refill friction stir spot welding (refill FSSW)of dissimilar magnesium (Mg) to galvanized steel. [...]

The performance of polycrystalline Ni-based superalloys is largely determined by the fraction and size of theintermetallic hardening phases, such as the γ′ phase. Understanding the evolution of the γ′ precipitate size andvolume fraction during the complex thermomechanical process chain is essential for optimizing the mechanicalproperties of polycrystalline Ni-based superalloys. [...]

The present study employs in-situ high-energy X-ray diffraction (HEXRD) to investigate the β-AlFeSi→α-Al(Fe,Mn)Si transformation in a 6063 Al alloy during homogenization heat treatment. The characteristics of HEXRD,combined with the experimental setup, enable an evaluation of the evolution of individual diffraction peaks as afunction of temperature and time. [...]

Decarbonizing the steel industry relies on a transition from carbon-intensive blast furnacetechnology to scrap-based secondary steelmaking using electric arc furnaces. Thistransition introduces tramp elements and leads to their gradual accumulation, which cansignificantly influence the functional properties of chemically sensitive steel grades. [...]

We present a comprehensive tensor network study of staggered, Wilson, and twisted mass fermions in the Hamiltonian formulation, using the massive two-flavor Schwinger model as a benchmark. Particular emphasis is placed on twisted mass fermions, whose properties in this context have not been systematically explored before. [...]

The identification of gamma-ray-induced air showers with Cherenkov telescopes suffers from contamination with a specific class of cosmic-ray-induced air showers. The predictions for this background show strong discrepancies between the available event generators. [...]

Context. The processes governing the production of astrophysical high-energy neutrinos are still a matter of debate, and the sources that originate them remain an open question. [...]

mechanicalproperties, usually involving complex, multi-step heat treatment procedures. This study investigates themicrostructural evolution and its impact on mechanical properties of an AM tool steel through successive heattreatment steps, including the as-built, spheroidized, quenched, sub-zero treated, and three repeated temperedconditions.
