The Gaia-ESO Survey: Empirical determination of the precision of stellar radial velocities and projected rotation velocities

Context. The Gaia-ESO Survey (GES) is a large public spectroscopic survey at the European Southern Observatory Very Large Telescope. Aims. A key aim is to provide precise radial velocities (RVs) and projected equatorial velocities (v sin i) for representative samples of Galactic stars, which will complement information obtained by the Gaia astrometry satellite. Methods. We present an analysis to e

Cause of late death after cardiac surgery in the very elderly: a single institution experience.

OBJECTIVES: The referrals of elderly for cardiac surgery are increasing. The aim of this retrospective study is to review the long-term survival and to identify causes of late death in elderly after cardiac surgery. DESIGN: Between 1990 and 1993, 130 octogenarians underwent cardiac surgery in our department. A majority (88%) had elective surgery. One hundred and nine patients (84%) were in New Yor

An inductorless 300MHz wideband CMOS power amplifier

The power amplifier tends to be one of the most demanding parts to fully integrate when building an entire radio on a CMOS chip. In this paper the design of a fully integrated RF power amplifier without inductors is described. As inductors in CMOS technology are associated with various problems, it is interesting to examine what performance can be achieved without them. An amplifier with an operat

Mortality and cancer morbidity in cohorts of asbestos cement workers and referents

Total and cause specific mortality and cancer morbidity were studied among 1929 asbestos cement workers with an estimated median cumulative exposure of 2.3 fibre (f)-years/ml (median intensity 1.2 f/ml, predominantly chrysotile). A local reference cohort of 1233 industrial workers and non-case referents from the exposed cohort were used for comparisons. The risk for pleural mesothelioma was signif

Structure of the vortex wake in hovering Anna's hummingbirds (Calypte anna).

Hummingbirds are specialized hoverers for which the vortex wake has been described as a series of single vortex rings shed primarily during the downstroke. Recent findings in bats and birds, as well as in a recent study on Anna's hummingbirds, suggest that each wing may shed a discrete vortex ring, yielding a bilaterally paired wake. Here, we describe the presence of two discrete rings in the wake

Cross-National User Priorities for Housing Provision and Accessibility - Findings from the European innovAge Project.

To develop an innovative information and communication technology (ICT) tool intended to help older people in their search for optimal housing solutions, a first step in the development process is to gain knowledge from the intended users. Thus the aim of this study was to deepen the knowledge about needs and expectations about housing options as expressed and prioritized by older people, people a

Lack of very strong association between pre-treatment fibrinogen and PAI-1 with long-term mortality after coronary bypass surgery

Aim: To explore the association between the coagulation protein fibrinogen and the fibrinolytic biomarker plasminogen activator inhibitor-1 ( PAI- 1) and the long- term mortality after coronary artery bypass grafting ( CABG). Patients and Methods: In 729 patients undergoing CABG at Sahlgrenska University Hospital, a blood sample for fibrinogen and PAI-1 was collected prior to the procedure. Patien

Prediction of IgG1 aggregation in solution.

Interest in monoclonal antibody aggregation is increasing as aggregates of biopharma-ceuticals can cause an immunogenic response when injected into the body. In this work a stoichiometric reaction model from concentration-time data is developed to predict the dimer ratio in stored antibody solutions over time. IgG1 was incubated at pH from 4.5 to 5.5, salt concentrations from 100 to 600 mmol/kg an

Development of Curative Therapies for Ewing Sarcomas by Interdisciplinary Cooperative Groups in Europe.

Curative therapies for Ewing sarcoma have been developed within cooperative groups. Consecutive clinical trials have systematically assessed the impact and timing of local therapy and the activity of cytotoxic drugs and their combinations. They have led to an increase of long-term disease-free survival to around 70% in patients with localized disease. Translational research in ES remains an area i

Assessing sources of uncertainty in formaldehyde air mass factors over tropical South America: Implications for top-down isoprene emission estimates

We use a nested-grid version of the GEOS-Chem chemistry transport model, constrained by isoprene emissions from the Model of Emissions of Gases and Aerosols from Nature (MEGAN), and the Lund-Potsdam-Jena General Ecosystem Simulator (LPJ-GUESS) bottom-up inventories, to evaluate the impact that surface isoprene emissions have on formaldehyde (HCHO) air-mass factors (AMFs) and vertical column densit

One-Dimensional Corrugation of the h-BN Monolayer on Fe(110)

We report on a new nanopatterned structure represented by a single atomic layer of hexagonal boron nitride (h-BN) forming long periodic waves on the Fe(110) surface. The growth process and the structure of this system are characterized by X-ray absorption (XAS), core-level photo-emission spectroscopy (CL PES), low-energy electron microscopy (LEEM), microbeam low-energy electron diffraction (mu LEE

Search for squarks and gluinos in events with isolated leptons, jets and missing transverse momentum at root s=8 TeV with the ATLAS detector

The results of a search for supersymmetry in final states containing at least one isolated lepton (electron or muon), jets and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported. The search is based on proton-proton collision data at a centre-of-mass energy root s = 8 TeV collected in 2012, corresponding to an integrated luminosity of 20 fb(-1). No

Association of polymorphisms in genes encoding hormone receptors ESR1, ESR2 and LHCGR with the risk and clinical features of testicular germ cell cancer.

Testicular germ cell cancer (TGCC) is the most common malignancy in young men. Genetic variants known to be associated with risk of TGCC only partially account for the observed familial risks. We aimed to identify additional polymorphisms associated with risk as well as histological and clinical features of TGCC in 367 patients and 214 controls. Polymorphisms in ESR2 (rs1256063; OR=0.53, 95% CI: 0

Panitumumab and Pegylated Liposomal Doxorubicin in Platinum-Resistant Epithelial Ovarian Cancer With KRAS Wild-Type: The PaLiDo Study, a Phase II Nonrandomized Multicenter Study.

OBJECTIVE: The increasing number of negative trials for ovarian cancer treatment has prompted an evaluation of new biologic agents, which in combination with chemotherapy may improve survival. The aim of this study was to investigate the response rate in platinum-resistant, KRAS wild-type ovarian cancer patients treated with pegylated liposomal doxorubicin (PLD) supplemented with panitumumab. PATI

Performance audit at the Swedish Supreme Audit Institution (SAI)

Supreme Audit Institutions (SAIs) constitute important democratic institutions, providing citizens with an independent analysis on how the Governmental Offices and the central public administration function. This paper reports on findings from a survey, submitted to all performance auditors at the Swedish SAI, on 3 May, 2011. The response rate was 70 per cent (65 out of 93 respondents). The survey

Irrigation of landfill leachates in energy forests - A technique to recover nutrients from municipal solid wastes

From an ecological point of view it is important to close nutrient cycles by recirculating mineral nutrients from the urban society back to agriculture and forestry, and thereby obtaining a sustainable resource utilisation. A part of this cycle is illustrated by irrigation of bioreactor landfill leachates on short rotation forests. This paper presents a budget for nutrients and heavy metals, begin

Insulin and free oestradiol are independent risk factors for benign prostatic hyperplasia

The aetiology of benign prostatic hyperplasia (BPH) remains unclear. The objective of the present study was to test the insulin, oestradiol and metabolic syndrome hypotheses as promoters of BPH. The design was a risk factor analysis of BPH in which the total prostate gland volume was related to endocrine and anthropometric factors. The participants studied were 184 representative men, aged 72-76 y
