This paper presents a new τ-lepton reconstruction and identification procedure at the ATLAS detector at the Large Hadron Collider, which leads to significantly improved performance in the case of physics processes where a highly boosted pair of τ-leptons is produced and one τ-lepton decays into a muon and two neutrinos (τμ), and the other decays into hadrons and one neutrino (τhad). By removing th

The pT-differential cross section of ω meson production in pp collisions at s = 13 TeV at midrapidity (|y| < 0.5) was measured with the ALICE detector at the LHC, covering an unprecedented transverse-momentum range of 1.6 < pT< 50 GeV/c. The meson is reconstructed via the ω → π+π−π0 decay channel. The results are compared with various theoretical calculations: PYTHIA8.2 with the Monash 2013 tune o

Side-channel attacks exploiting Plaintext-Checking (PC) and Decryption Failure (DF) oracles are a pressing threat to deployed post-quantum cryptography. These oracles can be instantiated from tangible leakage sources like timing, power, and microarchitectural behaviors, making them a practical concern for leading schemes based on lattices, codes, and isogenies. In this paper, we revisit chosen-cip

Surface strain rates around the southeastern dome of Hans Tausen Iskappe in Peary Land, North Greenland (82.5° N, 27.5° W), are determined from global positioning system surveys of a strain net. Average longitudinal surface strain rate increases towards the dome, from (1.4 ± 0.2) × 10−4 a−1 at 5–10 ice thicknesses from the divide to (2.4 ± 1.0) × 10−4 a−1 within 1 ice thickness from the divide. An

As the Hamming Quasi-Cyclic (HQC) cryptosystem was recently selected by NIST for standardization, a thorough evaluation of its implementation security is critical before its widespread deployment. This paper presents single-trace side-channel attacks that recover the full long-term secret key of HQC, experimentally evaluated on a protected Cortex-M4 implementation. We introduce two distinct attack

After the wider deglaciation of Northern Europe, pioneer reindeer populations started to move into southern Scandinavia; however, this process is poorly understood. In this paper we aim to reconstruct dispersal processes of reindeer into southern and western Sweden from the Late Palaeolithic through to the Early Mesolithic, when reindeer disappear from the record. Has presence of reindeer in south

The article explores how the pursuit of sustainability in screen media production intersects with incentivized industry mobility within the Baltic Sea region. It illuminates an under-researched area of screen mobility by focusing on Swedish mobile productions benefitting from the tax incentive scheme in Lithuania. The authors conceptualize recent tendencies in screen mobility as the Nordic–Baltic

The Lund jet plane (LJP) is measured for the first time in tt¯ events, using 140 fb-1 of s=13 TeV pp collision data collected with the ATLAS detector at the LHC. The LJP is a two-dimensional observable of the sub-structure of hadronic jets that acts as a proxy for the kinematics of parton showers and hadron formation. The observable is constructed from charged particles and is measured for R=1.0 a

Transplantation of human fetal ventral mesencephalic tissue in individuals with Parkinson's disease has yielded clinical benefits but also side effects, such as graft-induced dyskinesias. The open-label TransEuro trial ( NCT01898390 ) was designed to determine whether this approach could be further developed into a clinically useful treatment. Owing to poor availability of human fetal ventral mese

Gaining insight into structural and compositional transformations occurring at the electrode/electrolyte interface during the operation of electrochemical systems is fundamental to understanding and, thus, optimizing their performance. Such an analysis must be performed in operando conditions, owing to the potential, electrolyte and time dependence of these transformations. Here, the use of X-ray

The femtoscopic study of pairs of identical pions is particularly suited to investigate the effective source function of particle emission, due to the resulting Bose–Einstein correlation signal. In small collision systems at the LHC, pp in particular, the majority of the pions are produced in resonance decays, which significantly affect the profile and size of the source. In this work, we explicit

Hirshfeld atom refinement (HAR) provides a more realistic interpretation of crystallographic data than the standard independent atom model (IAM) by using aspherical atomic form factors derived from quantum mechanical (QM) calculations. With this aspherical description, it is possible to obtain improved atomic positions, atomic displacement parameters and correct bond lengths even for hydrogen atom

This study is part of a North West Europe (NWE) Interreg project called NWE-REGENERATIS that aims at the regeneration of past metallurgic sites and deposits through innovative circularity for raw materials. A novel geophysical methodology is developed to allow a 2D or 3D characterization of the recoverable metallic particles in terms of volume, type and grain sizes. We propose to integrate multi-m

Prostaglandin E2 (PGE2) is synthesized by cyclooxygenase 2 (COX-2) in the arachidonic acid pathway. PGE2 promotes cancer initiation and progression while facilitating chronic inflammation and immunosuppression, partly through regulation of programmed death ligand 1 (PD-L1) in tumor cells and tumor-associated macrophages. PGE2 also modulates Hippo signaling, enhancing nuclear Yes-associated protein
