The decays of the χb1(1P), χb2(1P), χb1(2P) and χb2(2P) mesons into the Υ(1S)μ+μ− final state are observed with a high significance using proton-proton collision data collected with the LHCb detector and corresponding to an integrated luminosity of 9 fb−1. The newly observed decays together with the Υ(2S) → Υ(1S)π+π− and Υ(3S) → Υ(2S)π+π− decay modes are used for precision measurements of the mass

A search for the lepton-flavor violating decays Bs0→φμ±τ is presented, using a sample of proton-proton collisions at center-of-mass energies of 7, 8, and 13 TeV, collected with the LHCb detector and corresponding to a total integrated luminosity of 9 fb-1. The τ leptons are selected using decays with three charged pions. No significant excess is observed, and an upper limit on the branching fracti

A study of resonant structures in B+→D∗+D-K+ and B+→D∗-D+K+ decays is performed, using proton-proton collision data at center-of-mass energies of s=7, 8, and 13 TeV recorded by the LHCb experiment, corresponding to an integrated luminosity of 9 fb-1. A simultaneous amplitude fit is performed to the two channels with contributions from resonances decaying to D∗-D+ and D∗+D- states linked by C parit

A search for the nonresonant Λc+→pμ+μ- decay is performed using proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the LHCb experiment, corresponding to an integrated luminosity of 5.4 fb-1. No evidence for the decay is found in the dimuon invariant-mass regions where the expected contributions of resonances is subdominant. The upper limit on the branching fraction of th

InP quantum dots have emerged as a promising ecofriendly alternative to cadmium-based QDs for next-generation display applications. However, red-emitting InP QDs synthesized via aminophosphine precursors still suffer from broad emission spectra and limited stability. In this study, we present a strain-engineered InP/ZnSe/ZnSexS1-x/ZnS QD structure featuring a gradient alloyed ZnSexS1-x shell that

The decays of the B+ meson to the final state D∗−Ds+π+ are studied in proton-proton collision data collected with the LHCb detector at centre-of-mass energies of 7, 8, and 13 TeV, corresponding to a total integrated luminosity of 9 fb−1. The ratio of branching fractions of the B+→D∗−Ds+π+ and B0→D∗−Ds+ decays is measured to be 0.173 ± 0.006 ± 0.010, where the first uncertainty is statistical and t

Although Fourier Neural Operators (FNOs) are computationally efficient and theoretically mesh-independent, their standard formulation assumes periodic boundary conditions and rectangular domains. When applied to non-periodic conditions, FNOs often exhibit oscillations, edge effects, and reduced accuracy. To mitigate these issues, this study investigates modifications to the baseline FNO, including

Otaliga mängder kritisk information om vår hälsa spolas ner varje dag. En toalettsits med osynligt inbyggd radar kan ta tillvara på denna information. Alla besöker toaletten varje dag, därav är den fylld av kliniskt relevant information, som hittills sällan använts för att övervaka hälsan. Förändringar i urin- och avföringsmängd, samt avföringens konsistens kan vara tidiga tecken på sjukdom, men rConstipation and irregular bowel movements are a daily challenge in elderly care, especially among patients with dementia who struggle to report their own toilet habits. This thesis investigates the possibility of using millimeter-wave pulsed coherent radar to passively monitor toilet visits and estimate both stool consistency and excreted quantity of urine and feces. This involved constructing a

This study investigates the concept of Selective Intentional Non-Compliance (SINC) in aviation. Deliberate, context-driven deviations from procedures motivated by safety in response to dynamic operational conditions. Based on a survey of 39 European commercial pilots, we analysed the prevalence, motivations, and perceived outcomes of procedural deviations. Nearly 43% reported deviating from s

In this article, we examine how the death of an author affects the value negotiation surrounding his or her oeuvre. As Barbara Herrnstein Smith has argued, literary value is not a fixed category but rather something that is created and negotiated in relation to various contexts and settings. For a high evaluation of the oeuvre of a given author – or a particular work – to be maintained, this value

In this article, we analyze the reception of the AI-generated poetry collection Ammaseus horisont: AI tolkar Karin Boye (2020) and discuss the more general debate about AI-generated literature in the Swedish press since November 2022, when OpenAI made ChatGPT available to the public. Specifically, we analyze the ways in which Swedish critics construct the literary value of Ammaseus horisont and un

This study explores how Chilean university students perceive entrepreneurship, exploring whether they see it as an opportunity to address societal challenges or primarily as an enterprise creation. The research focuses on how these perceptions vary by gender in front of sociodemographic, academic, and institutional influential factors. Using a quantitative approach, we collected data from a sample

While nostalgia has been a prominent theme in consumer research, little research explicitly addresses its dark side. This conceptual paper unpacks nostalgic echo chambers and their three axiological features of polarization, singularization, and ideologization to inform future consumer research on the implications of nostalgic echo chambers for consumers and society.

This paper describes measurements of the transverse momentum spectra of W and Z bosons produced in proton–proton collisions at centre-of-mass energies of s=5.02 TeV and s=13 TeV with the ATLAS experiment at the Large Hadron Collider. Measurements are performed in the electron and muon channels, W→ℓν and Z→ℓℓ (ℓ=e or μ), and for W events further separated by charge. The data were collected in 2017

A search for CP violation in the decay kinematics and vector-boson fusion production of the Higgs boson is performed in the H → ZZ* → 4ℓ (ℓ = e, μ) decay channel. The results are based on proton-proton collision data produced at the LHC at a centre-of-mass energy of 13 TeV and recorded by the ATLAS detector from 2015 to 2018, corresponding to an integrated luminosity of 139 fb−1.
