The Gaia-ESO Survey : Revisiting the Li-rich giant problem

The discovery of lithium-rich giants contradicts expectations from canonical stellar evolution. Here we report on the serendipitous discovery of 20 Li-rich giants observed during the Gaia-ESO Survey, which includes the first nine Li-rich giant stars known towards the CoRoT fields. Most of our Li-rich giants have near-solar metallicities and stellar parameters consistent with being before the lumin

Naumovozyma castellii: an alternative model for budding yeast molecular biology

Naumovozyma castellii (Saccharomyces castellii) is a member of the budding yeast family Saccharomycetaceae. It has been extensively used as a model organism for telomere biology research and has gained an increasing interest as a budding yeast model for functional analyses owing to its amenability to genetic modifications. Due to the suitable phylogenetic distance to S. cerevisiae the whole genome

Asymptotics of Chebyshev polynomials, I : subsets of R

We consider Chebyshev polynomials, (Formula presented.), for infinite, compact sets (Formula presented.) (that is, the monic polynomials minimizing the (Formula presented.)-norm, (Formula presented.), on (Formula presented.)). We resolve a (Formula presented.) year old conjecture of Widom that for finite gap subsets of (Formula presented.), his conjectured asymptotics (which we call Szegő–Widom as

Early mortality and morbidity after total hip arthroplasty in patients with femoral neck fracture : A nationwide study of 24,699 cases and 118,518 matched controls

Background and purpose — Early postoperative mortality is relatively high after total hip arthroplasty (THA) that has been performed due to femoral neck fracture. However, this has rarely been investigated after adjustment for medical comorbidity and comparison with the mortality in an age-matched population. We therefore assessed early mortality in hip fracture patients treated with a THA, in the

Visual grading evaluation of commercially available metal artefact reduction techniques in hip prosthesis computed tomography

Objective: To evaluate metal artefact reduction (MAR) techniques from four CT vendors in hip prosthesis imaging. Methods: Bilateral hip prosthesis phantom images, obtained by using MAR algorithms for single-energy CT data or dual-energy CT (DECT) data and by monoenergetic reconstructions of DECT data, were visually graded by five radiologists using 10 image quality criteria. Comparisons between th

A Clash with the System : Experiences of teaching film and media production in the south of Sweden

As a by-product of a meeting between my university’s vice-chancellor and the manager of the largest bank in the small southern town of Ystad in 2006, I, almost accidentally, soon after came to commence teaching and researching media production, production studies, media industries studies or film and media industry studies, as the subject finally came to be called at Lund. The teaching part involv

Impact of doping and diameter on the electrical properties of GaSb nanowires

The effect of doping and diameter on the electrical properties of vapor-liquid-solid grown GaSb nanowires was characterized using long channel back-gated lateral transistors and top-gated devices. The measurements showed that increasing the doping concentration significantly increases the conductivity while reducing the control over the channel potential and shifting the threshold voltage, as expe

Directional interpolation of multicomponent data

A method for interpolation of multicomponent streamer data based on using the local directionality structure is presented. The derivative components are used to estimate a vector field that locally describes the direction with the least variability. Given this vector field, the interpolation can be phrased in terms of the solution of a partial differential equation that describes how energy is tra

Driven self-Assembly

During the past few years we have seen an impressive number of studies using directed self-Assembly in soft matter research with a surprisingly wide range of underlying aims and goals. Here we will focus on field-driven colloidal selfassembly, and demonstrate how we can apply external electromagnetic fields in order to modulate the intrinsic interparticle interactions and induce additional directi

Eosinophilic airway inflammation in asthmatic patients is associated with an altered airway microbiome

Background: Asthmatic patients have higher microbiome diversity and an altered composition, with more Proteobacteria and less Bacteroidetes compared with healthy control subjects. Studies comparing airway inflammation and the airway microbiome are sparse, especially in subjects not receiving anti-inflammatory treatment. Objective: We sought to describe the relationship between the airway microbiom

Primary Production in African Drylands : Quantifying Supply and Demand Using Earth Observation and Socio-ecological Data

The human-environment connection in the mostly rural drylands of sub-Saharan Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. When plants remove carbon dioxide from the atmosphere through the process of phot

Overestimating the ‘Power Shift’: The US role in the failure of the Democratic Party of Japan’s ‘Asia Pivot’

In 2009 the Democratic Party of Japan came to power with a new foreign policy tailored to the regional and global power shift from the United States to China: a more equal relationship with the United States and improved relations with Japan’s Asian neighbours. Within nine months the new Prime Minister Hatoyama Yukio resigned and the foreign policy shift was jettisoned by his successors. Conventio

A transition perspective on alternatives to coal in Chinese district heating

China uses half the world’s annual coal consumption, since coal is the primary energy source for heating in urban areas, particularly in northern China. This entails significant challenges for urban air quality in China and for the global climate. Unlike the electricity and transportation sectors, the heating sector has received little attention from policy and research actors in China, despite ve

Individual consistency of long-distance migration in a songbird: significant repeatability of autumn route, stopovers and wintering sites but not in timing of migration

Through new tracking techniques, data on timing and routes of migration in long-distance migrant birds are accumulating. However, studies of the consistency of migration of the same individuals between years are still rare in small-sized passerine birds. This type of information is important to understand decisions and migration abilities at the individual level, but also for life history theory,

The feeling rules of victim offender mediation

This paper is based on an ethnographic study conducted in Sweden and focuses on the emotional aspect, both its rhetoric and interaction, of the victim offender mediation process. The emotion culture is examined, as well as the basic feeling rules that tell victims and offenders how to feel, value, and manage their own, and the other party's feelings in the mediation process. If mediation is done '

Characterization of hemicelluloses in process streams in thermomechanical and chemi-thermomechanical pulp mills

Increased interest in hemicelluloses as a renewable source of biopolymers has resulted in an interest in hemicelluloses in process streams in pulp mills. The aim of this study was to compare potential positions for the withdrawal of hemicelluloses from mechanical pulp mills. Samples were withdrawn at a total of fourteen positions from two thermomechanical and two chemi-thermomechanical pulp mills.
