We experimentally observe longer than long trajectory influence in high-order harmonic generation (HHG) by varying the peak intensity of the driving laser field either through direct attenuation or by chirping the laser pulse. Using a theoretical Gaussian beam model to simulate spatial interference resulting from quantum path interference, we show that the measured interference patterns cannot be

The self avoiding walk (SAW) model of the polymer has been extended to study the equilibrium properties of double stranded DNA (dsDNA) where two strands of the dsDNA are modeled by two mutually attracting self-avoiding walks (MASAWs) in the presence of an attractive surface. We study simultaneous adsorption and force induced melting transitions and explore different phases of DNA. It is observed t

We present state-of-the-art high-precision theory predictions for the dominant angular coefficients parametrizing the spin-correlations in the production and decay of a W-boson produced at transverse momentum larger than 30 GeV. The computation at NNLO QCD and NLO EW accuracy are combined to obtain differential distributions in the W-boson transverse momentum and rapidity. The found results show u

Implementing solar photovoltaic systems in the built environment (BEPV) is critical for the construction sector’s contribution to mitigating climate change. While previous studies give various insights into innovation implementation, the challenges to value co-creation by construction actors remain underexplored. By studying the alignment of business ecosystems implementing BEPV in the Swedish bui

Abstract in GermanDas Thema dieses Beitrags ist die Übersetzung deutscher Partizipialkonstruktionen ins Schwedische – ein Thema, dem die bisherige Forschung kaum Aufmerksamkeit geschenkt hat. Die Studie ist sowohl quantitativer als auch qualitativer Natur. Als Korpus dienen deutsche Sachprosatexte und ihre schwedischen Übersetzungen, von denen anzunehmen ist, dass sie im Einklang mit den entsprech

Over the past years, eosinophils have become a focus of scientific interest, especially in the context of their recently uncovered functions (e.g. antiviral, anti-inflammatory, regulatory). These versatile cells display both beneficial and detrimental activities under various physiological and pathological conditions. Eosinophils are involved in the pathogenesis of many diseases which can be class

The division between rural and urban values and practices is a classic theme in disciplines such as European ethnology. During the last decades, the urban/rural divide seem to be renegotiated. Traditional, small scale agriculture and food production encapsulates values on display at many dinner tables of the upper middle urban class. This has lead to new business opportunities for rural actors, of

This chapter is a case study of #Swedengate, a social media controversy evoked by the supposedly Swedish custom not to invite children's playmates to partake in the family dinner. The practice seems to be in direct confrontation with norms of commensality and reciprocity, and the chapter deals with the cultural context and implications of the practice. The empirical material is an open-ended quest

The stability of the human tendency to eat in groups is remarkable. We find it to be valued and mostly desirable across geographical locations, cultures, and historical time periods. Yet, there is a great deal of variety in how the practice is expressed, how individuals experience it, and how the sharing of meals is understood culturally. This chapter focuses on three facets of eating together tha

A search for light long-lived neutral particles with masses in the O(MeV–GeV) range is presented. The analysis targets the production of long-lived dark photons in the decay of a Higgs boson produced via gluon–gluon fusion or in association with a W boson. Events that contain displaced collimated Standard Model fermions reconstructed in the calorimeter or muon spectrometer are selected in 139 fb−1

A measurement of observables sensitive to effects of colour reconnection in top-quark pair-production events is presented using 139 fb - 1 of 13 TeV proton–proton collision data collected by the ATLAS detector at the LHC. Events are selected by requiring exactly one isolated electron and one isolated muon with opposite charge and two or three jets, where exactly two jets are required to be b-tagge

This paper proposes a motion control scheme for robots operating in a dynamic environment with concave obstacles. A Model Predictive Controller (MPC) is constructed to drive the robot towards a goal position while ensuring collision avoidance without direct use of obstacle information in the optimization problem. This is achieved by guaranteeing tracking performance of an appropriately designed re

Cross-sections for the production of a Z boson in association with two photons are measured in proton–proton collisions at a centre-of-mass energy of 13 TeV. The data used correspond to an integrated luminosity of 139 fb - 1 recorded by the ATLAS experiment during Run 2 of the LHC. The measurements use the electron and muon decay channels of the Z boson, and a fiducial phase-space region where the

Results of a measurement of dimuon photoproduction in nonultraperipheral Pb + Pb collisions at √sNN = 5.02 TeV are presented. Themeasurement uses ATLAS data from the 2015 and 2018 Pb + Pb data-taking periods at the LHC with an integrated luminosity of 1.94 nb.1. The γγ → μ+ μ- pairs are identified via selections on pair momentum asymmetry and acoplanarity. Differential cross sections for dimuon pr

This paper presents direct searches for lepton flavour violation in Higgs boson decays, H → eτ and H → μτ, performed using data collected with the ATLAS detector at the LHC. The searches are based on a data sample of proton-proton collisions at a centre-of-mass energy s = 13 TeV, corresponding to an integrated luminosity of 138 fb −1. Leptonic (τ → ℓνℓ ντ) and hadronic (τ → hadrons ντ) decays of t

In this paper, we introduce OT-PCA, a novel approach for conducting Plaintext-Checking (PC) oracle based side-channel attacks, specifically designed for Hamming Quasi-Cyclic (HQC). By calling the publicly accessible HQC decoder, we build offline templates that enable efficient extraction of soft information for hundreds of secret positions with just a single PC oracle call. Our method addresses cr
