To cope with the challenging environment of the planned high luminosity upgrade of the Large Hadron Collider (HL-LHC), scheduled to start operation in 2029, CMS will replace its entire tracking system. The requirements for the tracker are largely determined by the long operation time of 10 years with an instantaneous peak luminosity of up to 7.5 x 10$^{34}$ cm$^{-2}$s$^{-1}$ in the ultimate performance scenario.

We present a novel model that may provide an interpretation for a class of non-repeating fast radio bursts (FRBs) – short (⁠|$\lt 1~\rm {s}$|⁠), bright (⁠|$0.1 - 1000~\rm {Jy}$|⁠) bursts of MHz–GHz frequency radio waves. The model has three ingredients – compact object, a progenitor with effective magnetic field strength around 10^10 Gauss, and high-frequency (MHz–GHz) gravitational waves (GWs). [...]

The High-Luminosity Large Hadron Collider (HL-LHC) represents a significant leap inthe pursuit of fundamental physics. Scheduled to operate at a center-of-mass energy of14 TeV and a peak instantaneous luminosity up to 7. [...]

Talc, as an important class of clay minerals constituting subducting oceanic crust, has long been known to undergo interlayer expansion by ~6% to contain net ~13 wt.% water into the ‘so-called’ 10 Å phase. Although subduction fluid is mildly alkaline and includes various salts and other dissolved species, its effect on the stability of subducting minerals has not yet been considered. [...]

Quantum computing provides a novel avenue towards simulating dynamical phenomena, and, in particular, scattering processes relevant for exploring the structure of matter. However, preparing and evolving particle wave packets on a quantum device is a nontrivial task. [...]

The use of metal single atoms (SAs) as co-catalysts on semiconductors has emerged as a promising technology to enhance their photocatalytic hydrogen production performance. In this study, we describe the deposition of very low amounts of Pt SAs (<0.1 at %) on exfoliated graphitic carbon nitride (C3N4) by a direct Pt−deposition approach from highly dilute chloroplatinic acid precursors. [...]

The Pixel Luminosity Telescope is a silicon pixel detector dedicated to luminosity measurement at the CMS experiment at the LHC. It is located approximately 1.75 m from the interaction point and arranged into 16 “telescopes”, with eight telescopes installed around the beam pipe at either end of the detector and each telescope composed of three individual silicon sensor planes. [...]

The surface chemistry of the Fischer-Tropsch catalytic reaction over Co hasstill several unknows. Here, we report an in-situ X-ray photoelectron spectro-scopy study of Co 0001ð Þ and Co(1014), and in-situ high energy surface X-raydiffraction of Co 0001ð Þ, during the Fischer-Tropsch reaction at 0.15 bar - 1 barand 406 K - 548 K in a H2/CO gas mixture. [...]

The Hands-on Lab offers practical insights and an open exchange for publication cost managers. The focus is on the effective processing of publication fees in scientific institutions as a contribution to the sustainable establishment of an information budget. [...]

Within the framework of openCost, the project team has developed a metadata schema for costs associated with scholarly publishing, in collaboration with a number of various stakeholders. In addition to modelling cost data for individual items, modelling of contracts and their associated costs has also been developed. [...]
