“Beak larva” is a collective term for four fossil specimens from Kachin amber, which are holometabolan larvae with a forward-projecting beak. This arrangement is very unusual, and so far it has been unclear whether these specimens are larvae of beetles or of lacewings [...]

High entropy alloys (HEAs) are unique and novel materials with remarkable properties that render themcompetitive for developing key engineering applications within modern engineering sectors. In the present study,a AlCoCrFeNi HEA was gas tungsten arc welded to 316 L stainless steel, with the aim of assessing the compatibilityin terms of microstructure and mechanical performance. [...]

The transformation of retained austenite under mechanical load has a significant impact on the mechanicalproperties of high-strength low-alloy steels and weld metals. Here, we have studied the stability of retainedaustenite in a microalloyed, multipass high-strength all-weld metal using in situ high-energy X-ray diffractionphase quantification during tensile loading. [...]

This study investigated the microstructure, tensile strength, wettability, and steam oxidation resistance of as-castIN713C fabricated by vacuum lost-wax casting. A comprehensive array of techniques, including thermodynamicsimulations, synchrotron X-ray diffraction, differential thermal analysis, optical and electron microscopy, tensiletesting, sessile drop testing, and a high-temperature oxidation experiment, was employed to characterize the ascastmicrostructure. [...]

In this work, we present a comprehensive study of Al doped VN thin films with x = 0, 35, 60, 71, 84, 100 % in V$_{1−x}$Al$_x$N. These samples were deposited using a reactive magnetron sputtering process at room temperature (300 K), keeping the partial nitrogen gas flow fixed at 25 % [...]

We perform a detailed study of the cosmological constraints on the decay of a relic particle ϕ into neutrinos, ϕ → νν̅, in particular those arising from the observed light-element abundances in the early Universe. Several processes are relevant, including final-state radiation associated with the decay, as well as subsequent interactions of the injected neutrinos with the thermal background neutrinos or between themselves. [...]

Parton densities are obtained from a solution of the extended DGLAP-type evolution equation that includes both QCD and electroweak contributions. The equations are solved using the Parton-Branching (PB) approach, and the evolution is performed at next-to-leading order for QCD partons and leading order for electroweak bosons. [...]

Dissimilar fusion welding between NiTi shape memory alloy and AlCoCrFeNi$_{2.1}$, eutectic high entropy alloy wasachieved using a combination of Nb and Cu interlayers. Both base metals exhibit unique properties that complementeach other making them attractive for integration in smart systems. [...]

At the Large Hadron Collider, the WbWb final state is expected to be dominated by $ t\overline{t} $ production with a contribution from single-top processes. Differential cross-sections for WbWb production in the dilepton decay channel are measured at the particle level as a function of various kinematic variables [...]
