4MOST - 4-metre multi-object spectroscopic telescope

The 4MOST consortium is currently halfway through a Conceptual Design study for ESO with the aim to develop a wide-field (>3 square degree, goal >5 square degree), high-multiplex (>1500 fibres, goal 3000 fibres) spectroscopic survey facility for an ESO 4m-class telescope (VISTA). 4MOST will run permanently on the telescope to perform a 5 year public survey yielding more than 20 million spectra at

Put a bet on it : Can self-funded commitment contracts curb fitness procrastination?

We investigate the use of a highly scalable intervention to help individuals achieve their physical activity goals: self-funded commitment contracts. Using a randomised experiment, we compare the effect of soft (non-incentivised) and hard (incentivised) contracts among 1629 members of a gym in Stockholm, Sweden. We find a significant positive impact of being offered a hard contract on monthly visi

Direct band gap white light emission from charge carrier diffusion induced nanowire light-emitting diodes

Light-emitting diodes (LEDs) have been investigated during the past decades, for which a major challenge is total internal reflection that limits the light extraction efficiency. ‘Nanotree’ LEDs elegantly solve this bottleneck. Lower band gap nanowire branches are grown on higher band gap core wires. Charge carriers diffuse into the branches and recombine there. Total internal reflection is impede

Consistency between the ACGIH TLV for hand activity and proposed action levels for wrist velocity and forearm muscular load based on objective measurements : an example from the assembly industry

Objectives. This study aimed to investigate the consistency between results of the American Conference for Governmental Occupational Hygienists (ACGIH) threshold limit value (TLV) for hand activity and proposed action levels of objective measurements in risk assessments of work-related musculoskeletal disorders. Methods. Wrist velocities and forearm muscular load were measured for 11 assemblers du

LES of pilot n-heptane ignition and its interaction with the lean premixed methane–air mixture in a dual-fuel combustion engine

Large eddy simulations of pilot fuel ignited, lean premixed, natural gas engines are performed to study the pilot-ignition process and its subsequent interaction with the premixed charge. The injection pressure (Pinj) and injection duration (Δinj) are varied (i.e. 800 bar/760μs, 800 bar/500μs, and 400bar/760μs) to study the impact of the injection process on the subsequent combustion evolution. Op

Cohort study of prediction of venous thromboembolism in emergency department patients with extremity symptoms

Despite diagnostic algorithms, identification of venous thromboembolism (VTE) in emergency departments (ED) remains a challenge. We evaluated symptoms, background, and laboratory data in 27,647 ED patients presenting with pain, swelling, or other symptoms from the extremities, and identified predictors of VTE diagnosis within one year. Predictors of a clinical decision to perform phlebography, ult

The welfare state

The first keyword, Welfare State, sets out to problematise the term itself. The welfare state is a national construct, a ‘national social state’ as Etienne Balibar calls it. Thus, transnational or global migration is often construed as a disruptive force, potentially destabilising the welfare state and the nation. This keyword entry critically examines common conceptions of what the welfare state

Activity and participation among people with Late Effects of Polio admitted to comprehensive rehabilitation

Late effects of polio (LEoP), a chronic progressive neuromuscular condition that affects people who have had polio earlier in life. LEoP manifests with new symptoms such as muscle weakness, fatigue, and pain, and can also have consequences for an individual’s level of activity and participation. People with LEoP can benefit from comprehensive rehabilitation, with focus on enabling activity and par

Whole-channel acoustic energy and acoustophoretic efficiency frequency spectrum by the in-flow focusing method

The in-flow focusing method, introduced herein, enables rapid and straightforward measurements of the whole-channel acoustic energy of acoustic flow-through devices. The method is applied to assess the whole-channel acoustic energy and acoustophoretic efficiency frequency spectra of a bottom-actuated silicon-glass and a side-actuated glass chip. The input variables are the time-independent geometr

Self-Oxidation of the Atmospheres of Rocky Planets with Implications for the Origin of Life

Rocky planets may acquire a primordial atmosphere by the outgassing of volatiles from their magma ocean. The distribution of O between H2O, CO, and CO2 in chemical equilibrium subsequently changes significantly with decreasing temperature. We consider here two chemical models: one where CH4 and NH3 are assumed to be irrevocably destroyed by photolysis and second where these molecules persist. In t

a choir for people with experience of being infertility treatment .LYTTEKOR is an artistic research project for individuals with experiences of fertility treatment. We work creatively with listening, voice, and body in a confidential and caring space.Our approach is based on vocal compositions inspired by Deep Listening (a method developed by Pauline Oliveros). Through listening, we open up to greater self-acceptance, understanding of our situation, and shared ex

Going Beyond the Tropes of ‘Friendship’ and ‘Modernization’ : Internal Colonialism in Siam and Scandinavia in the Age of Empire

This article contributes to a reconceptualization of the relationship between Siam and Scandinavia at the turn of the twentieth century. At that time, the relationship was manifested by the presence of a large group of Scandinavian, mainly Danish, entrepreneurs and professionals in Siam and repeated visits between the royal houses in Siam and the Scandinavian countries. The tropes of friendship an

Formation of 258Rf in drift plus diffusion dynamics

We present calculations on the formation of 258Rf in the reaction 50Ti+208Pb within the Langevin framework. The initital stage after contact of the colliding nuclei is dominated by a drift in the center-of-mass direction, while the subsequent process of forming a compound nucleus is diffusion dominated. The probability for the composite system to diffuse over the inner saddle is obtained by perfor

European stroke organisation and European society for minimally invasive neurological therapy guideline on acute management of basilar artery occlusion

The aim of the present European Stroke Organisation (ESO) guideline is to provide evidence-based recommendations on the acute management of patients with basilar artery occlusion (BAO). These guidelines were prepared following the Standard Operational Procedure of the ESO and according to the GRADE methodology. Although BAO accounts for only 1%–2% of all strokes, it has very poor natural outcome.

Were COVID-19 lockdowns worth it? A meta-analysis

Following the onset of the COVID-19 pandemic, an unprecedented use of mandatory lockdowns—defined as the imposition of at least one compulsory, non-pharmaceutical intervention—took place. We conduct a meta-analysis to determine the effect of these lockdowns on COVID-19 mortality. Our meta-analysis finds that lockdowns in the spring of 2020 had a relatively small effect on COVID-19 mortality and is
