The zip file 'Masspec_data.zip': Contains the raw data of the mass spectrometer measurements during the operando experiment (.rga and .ana files) for both samples. The folder also contains the exported data (.txt files) for readability and accessibility. [...]

We present the La Silla Schmidt Southern Survey (LS4), a new wide-field, time-domain survey to be conducted with the 1 m ESO Schmidt telescope. The 268 megapixel LS4 camera mosaics 32 2k × 4k fully depleted CCDs, providing a ∼20 deg$^{2}$ field of view with 1$^{″}$ pixel$^{−1}$ resolution. [...]

The single top quark $t$-channel production cross section is measured in proton-proton collisions at the CERN LHC at $\sqrt{s}$ = 5.02 TeV, using data recorded with the CMS detector in 2017, corresponding to an integrated luminosity of 302 pb$^{-1}$, and resulting in the first CMS measurement of the process at that energy. Events with one electron or muon and two or more jets, among which at least one is identified as originating from a b quark fragmentation, are analyzed. [...]

Strong first-order phase transitions in a dark sector offer a compelling explanation for the stochastic gravitational wave background in the nano-Hertz range recently detected by pulsar timing arrays (PTAs). We explore the possibility that such a phase transition at the same time gives mass to a stable fermion that accounts for the observed dark matter abundance and leads to testable effects in laboratory experiments. [...]

Tooth enamel of most mammals shows alternating light-dark bands, called Hunter-Schreger bands (HSB), in longitudinal sections caused by a decussating arrangement of bundles of prisms, the unit building blocks of mammalian enamel. HSB is thought to increase resistance to abrasive food and mitigate crack propagation and hence is considered a mammalian adaptation to high-efficiency mastication. [...]

The low-temperature metallic phase of 1T-TaS$_2$ may originate from current- and voltage-driven destabilization of the commensurate charge density wave (CDW) in a strongly correlated Mott insulator, alongside the robust yet rarely realized influence of intrinsic electronic distortions. Electrical pulse-driven transport, combined with second harmonic response, reveals abrupt switching, negative differential resistance (NDR), and multiscale domain-wall reorganization. [...]

Cosmological first order phase transitions are a frequent phenomenon in particle physics beyond the Standard Model, and the corresponding gravitational wave signal offers a key probe of new physics in the early Universe. Depending on the underlying microphysics, the transition can exhibit either direct or inverse hydrodynamics, leading to a different phenomenology. [...]

The tracking system of the ATLAS experiment will be upgraded for the upcoming High-Luminosity Upgrade of the LHC (HL-LHC). The main building blocks of the new strip tracker aresilicon-strip modules that consist of a sensor and hybrid PCB’s. [...]
