Measurements of spin correlation in top quark pair production are presented using data collected with the ATLAS detector at the LHC with proton-proton collisions at a center-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 4.6 fb(-1). Events are selected in final states with two charged leptons and at least two jets and in final states with one charged lepton and at least four

We report on detailed Monte Carlo comparisons of selection variables to separate tbH± signal events from the standard model tt background using an iterative discriminant analysis (IDA) method. While kinematic differences exist between the two processes whenever m_{Hpm≠}m_Wpm , the exploration of the spin difference between the charged Higgs and the W± gauge boson becomes crucial in the particularl

Background: To our knowledge there is no report in the literature on measurements of vertebral rotation with low-dose computed tomography (CT) in prone position.Aims: To describe and test the reliability of this new method, compare it with other methods in use and evaluate the influence of body position on the degree of vertebral rotation measured by different radiological methods.Study design: Re

Integrating quantum systems with machine learning models gives rise to quantum machine learning, which introduces new data processing and analysis capabilities. One approach is the use of quantum extreme learning machines, which combine a physical quantum reservoir with a single-layer artificial neural network. The advantage of utilizing a quantum reservoir, instead of a classical system, lies in

A highly tunable linear triple quantum dot (TQD) device is realized in a single-crystalline pure-phase InAs nanowire using a local finger gate technique. The electrical measurements show that the charge stability diagram of the TQD can be represented by three kinds of current lines of different slopes and a simulation performed based on a capacitance matrix model confirms the experiment. We show t

In this article we aim to highlight the potential of forgotten grave materials in our museum depositories for gaining insights into prehistoric life. By applying a multi-proxy approach to the skeletal remains of two graves of uncertain types from Falbygden in western Sweden, we were able to acquire new knowledge of burial practices, subsistence, health and mobility in Late Neolithic and Early Bron

What are the most important clues to look for in the fight against Alzheimer’s disease? How can more efficient solar cells and environmentally friendly solvents be created? And how dangerous are nanoplastics? Our chemistry researchers tackle pressing issues across a wide range of societal challenges. The environment, health and renewable resources are a particular focus. Protein research for healt

Single and double quantum dot devices are realized in InGaAs/InP heterostructures by top gating technology with incorporated High-kappa HfO2 gate dielectric layers. At 300 mK, Coulomb blockade effects are observed in as-fabricated devices, and the charge states can be measured by the integrated quantum point contacts. The developed technology should stimulate the research on quantum devices made f

The description of quantum transport in the strong system-reservoir coupling regime poses a significant theoretical and computational challenge that demands specialized tools for accurate analysis. RealTimeTransport is a new open-source C++ library that enables the computation of both stationary and transient transport observables for generic quantum systems connected to metallic reservoirs. It co

This study investigates the relationship between music, cultural practice and space at Hemgården, a grassroots youth cultural centre in Lund, Sweden. Drawing on semi-structured interviews with three staff members and four regular members, alongside an analysis of 104 music event posters from 2013 to 2026, the research examines how Hemgården has evolved in response to social and political change, h

A new technology has emerged the last decade, based on a new group of materials; Soft Magnetic Composites (SMC), instead of laminated steel that facilitates production of products with more integrated, smaller, lighter, less costly and highly efficient electromagnetic machines. The application of this technology is a change of paradigm regarding integrated design and energy efficiency. This articl

Two in situ 'nanoreactors' for high-resolution imaging of catalysts have been designed and applied at the hard X-ray nanoprobe endstation at beamline P06 of the PETRA III synchrotron radiation source. The reactors house samples supported on commercial MEMS chips, and were applied for complementary hard X-ray ptychography (23 nm spatial resolution) and transmission electron microscopy, with additio

Carotid-femoral pulse wave velocity (cfPWV) and its risk factors may differ between various populations. Few studies have compared the risk profiles associated with cfPWV in different ethnic populations. The study population included 4321 subjects from Shanghai, China (n = 1272, age 75.0 ± 6.5 years, female 57.3%) and Malmö, Sweden (n = 3049, age 72.5 ± 5.5 years, female 60.4%). cfPWV was measured

We present measurements of the potential profile of etched GaInAs/InP billiards and show that their energy gradients are an order of magnitude steeper than those of surface-gated GaAs/AlGaAs billiards. Previously observed in GaAs/AlGaAs billiards, fractal conductance fluctuations are predicted to be critically sensitive to the billiard profile. Here we show that, despite the increase in energy gra
