1906.10127 | Probing Proton Structure at the Large Hadron electron Collider | For the foreseeable future, the exploration of the high-energy frontier will be the domain of the Large Hadron Collider (LHC). Of particular significance will be its high-luminosity upgrade (HL-LHC), which will operate until the mid-2030s. In this endeavour, for the full exploitation of the HL-LHC physics potential an ... | [

2201.08069 | Analysis of the distribution, rotation and scale characteristics of solar wind switchbacks: comparison between the first and second encounters of Parker Solar Probe | The S-shaped magnetic structure in the solar wind formed by the twisting of magnetic field lines is called a switchback, whose main characteristics are the reversal of the magnetic field and the significant increase in the solar wind radial velocity. We identify 242 switchbacks during the first two encounters of Parker... | [

0911.3361 | Mass loss from inhomogeneous hot star winds I. Resonance line formation in 2D models | Small-scale clumping in the winds of hot, massive stars is conventionally included in spectral analyses by assuming optically thin clumps, a void inter-clump medium, and a smooth velocity field. To reconcile investigations of different diagnostics within such models, a highly clumped wind with very low mass-loss rates ... | [

0911.5612 | Massive protostars as gamma-ray sources | Massive protostars have associated bipolar outflows with velocities of hundreds of km s$^{-1}$. Such outflows can produce strong shocks when interact with the ambient medium leading to regions of non-thermal radio emission. We aim at exploring under which conditions relativistic particles are accelerated at the termina... | [

1106.5057 | Using a Differential Emission Measure and Density Measurements in an Active Region Core to Test a Steady Heating Model | The frequency of heating events in the corona is an important constraint on the coronal heating mechanisms. Observations indicate that the intensities and velocities measured in active region cores are effectively steady, suggesting that heating events occur rapidly enough to keep high temperature active region loops c... | [

2111.12431 | A Large-Scale Multi-Rider Matching Problem with Reneging Passengers | This paper studies a large-scale ride-matching problem in a transport center with a large number of passengers who are different in terms of destinations and travel preferences. Passengers with similar itineraries can match each other and share the same vehicle for their potentially different destinations; and reneging... | [

1805.11049 | Induced Chern-Simons modified gravity at finite temperature | We calculate the linearized four-dimensional gravitational Chern-Simons term at the finite temperature, show its finiteness and explicitly demonstrate that its transversal part matches the known result for the chiral vortical conductivity. | [

It is shown, via the smoothing effect of the Schr\"odinger flow, that the (sharp) result proved by Dahlberg and Kenig for initial data in Sobol... | [

The code computes $(g-2)_\mu$ precisely, by taking into account the latest two-loop corrections and by performing the calculation in a physical on-shell renormalization scheme. I... | [

We also prove the uniqueness of solutions of Fu-Yau equation when the slope parameter $\alpha$ is negative. | [

An intriguing feature of this theory is that the divergence of the matter energy--momentum tensor does not vanish identically. We explore the physical and cosmological implications o... | [
