A network of social security bodies – European administrative cooperation under Regulation (EC) No 883/2004

In the EU regime on the coordination of social security, there are rules and principles on cross-border administrative cooperation. Through these legal mechanisms, a number of cooperation structures are established with the Administrative Commission as a central point. Within these structures, national social security bodies provide assistance, communicate directly, solve conflicts of interpretati

Carbon quality rather than stoichiometry controls litter decomposition in a tropical rain forest

1. Ecological stoichiometry predicts important control of the relative abundance of the key elements carbon (C), nitrogen (N) and phosphorus (P) on trophic interactions. In a nutrient-poor Amazonian lowland rain forest of French Guiana, we tested the hypothesis that decomposers exploit stoichiometrically diverse plant litter more efficiently, resulting in faster litter decomposition compared to li

Ovarian cancer linked to lynch syndrome typically presents as early-onset, non-serous epithelial tumors

Objective. Heredity is a major cause of ovarian cancer and during recent years the contribution from germline mismatch repair (MMR) gene mutations linked to Lynch syndrome has gradually been recognized. Methods. We characterized clinical features, tumor morphology and mismatch repair defects in all ovarian cancers identified in Swedish and Danish Lynch syndrome families. Results. In total, 63 epit

Photon upconversion in degenerately sulfur doped InP nanowires.

Radiative recombination in degenerately n-doped InP nanowires is studied for excitation above and below the Fermi energy of the electron gas, using photoluminescence. Laser-induced electron heating is observed, which allows absorption below the Fermi energy. We observe photon upconversion where photo-excited holes recombine with high |k| electrons. This can be attributed to hole scattering to high

Earth system governance: a research framework

The Earth System Science Partnership, which unites all major global change research programmes, declared in 2001 an urgent need to develop "strategies for Earth System management". Yet what such strategies might be, how they could be developed, and how effective, efficient and equitable such strategies would be, remains unspecified. It is apparent that the institutions, organizations and mechanism

The chaperone domain BRICHOS prevents CNS toxicity of amyloid-beta peptide in Drosophila melanogaster

Aggregation of the amyloid-beta peptide (A beta) into toxic oligomers and amyloid fibrils is linked to the development of Alzheimer's disease (AD). Mutations of the BRICHOS chaperone domain are associated with amyloid disease and recent in vitro data show that BRICHOS efficiently delays A beta 42 oligomerization and fibril formation. We have generated transgenic Drosophila melanogaster flies that

A five-coordinate [2Fe-2S] cluster.

A unique [2Fe-2S] cluster (1) with genuinely five-coordinate ferric ions has been synthesized and investigated both structurally and spectroscopically. The crystal structure of 1 as well as (1)H NMR data reveal that 2,6-bis(imidazol-2-yl)pyridine binds to the [2Fe-2S] core as a tridentate capping ligand. DFT calculations showing spin density on all coordinating atoms support this finding. Cluster

Parallel and Distributed Vision Algorithms Using Dual Decomposition

We investigate dual decomposition approaches for optimization problems arising in low-level vision. Dual decomposition can be used to parallelize existing algorithms, reduce memory requirements and to obtain approximate solutions of hard problems. An extensive set of experiments are performed for a variety of application problems including graph cut segmentation, curvature regularization and more

The effect of treatment with bisoprolol-first versus enalapril-first on cardiac structure and function in heart failure

Background: In CIBIS III, initiating chronic heart failure (CHF) treatment with bisoprolol (target dose 10 mg q.d.) followed by combination therapy with enalapril (target dose 10 mg b.i.d.), compared to the opposite order, showed similar effects on survival and hospitalization. By echocardiography, we evaluated the effects of these treatment strategies on cardiac structure and function. Methods: I

Pure and social disparities in distribution of dentists: a cross-sectional province-based study in iran.

During past decades, the number of dentists has continuously increased in Iran. Beside the quantity, the distribution of dentists affects the oral health status of population. The current study aimed to assess the pure and social disparities in distribution of dentists across the provinces in Iran in 2009. Data on provinces' characteristics, including population and social situation, were obtained

Regional values of diffusional kurtosis estimates in the healthy brain.

PURPOSE: To provide estimates of the diffusional kurtosis in the healthy brain in anatomically defined areas and list these along previously reported values in pathologies. MATERIALS AND METHODS: Thirty-six volunteers (mean age = 33.1 years; range, 19-64 years) underwent diffusional kurtosis imaging. Mean kurtosis (MK), radial kurtosis (RK), mean diffusivity (MD), radial diffusivity (RD), and frac

Acoustoelastic Effects on the Resonance Frequencies of Prestressed Concrete Beams – Short-term Measurements

In this study resonant acoustic spectroscopy was applied during static loading and unloading of three prestressed concrete beams in the context of acoustoelasticity. At each load step multiple modes of vibration were measured using an accelerometer and a small impact source. It was found that the measured resonance frequencies increased with increasing compressive stress in a manner which can be p

Human isolates of Listeria monocytogenes in Sweden during half a century (1958-2010)

Isolates of Listeria monocytogenes (n = 932) isolated in Sweden during 1958-2010 from human patients with invasive listeriosis were characterized by serotyping and pulsed-field gel electrophoresis (PFGE) (AscI). Of the 932 isolates, 183 different PFGE types were identified, of which 83 were each represented by only one isolate. In all, 483 serovar 1/2a isolates were distributed over 114 PFGE types

Coronary liposuction during percutaneous coronary intervention: evidence by near-infrared spectroscopy that aspiration reduces culprit lesion lipid content prior to stent placement.

Intracoronary near-infrared spectroscopy (NIRS) in ST-segment elevation myocardial infarction (STEMI) has demonstrated substantial lipid in STEMI culprit plaques. Thrombus aspiration during primary PCI reduces distal embolization and improves reperfusion. This study was performed to examine if aspiration thrombectomy reduces the lipid content of acute coronary syndrome (ACS) culprit plaques.

Search for massive supersymmetric particles decaying to many jets using the ATLAS detector in pp collisions at root s=8 TeV

Results of a search for decays of massive particles to fully hadronic final states are presented. This search uses 20.3 fb(-1) of data collected by the ATLAS detector in root s = 8 TeV proton-proton collisions at the LHC. Signatures based on high jet multiplicities without requirements on the missing transverse momentum are used to search for R-parity-violating supersymmetric gluino pair productio

Improved temperature precision in rotational coherent anti-Stokes Raman spectroscopy with a modeless dye laser

Single-shot thermometry with dual-broadband rotational coherent anti-Stokes Raman spectroscopy that employs amplified spontaneous emission from a broadband modeless dye laser has been examined. Evaluation of single-shot spectra of air, N-2, and O-2 showed an improved temperature precision at room temperature compared with the precision obtained with a conventional dye laser. A comparison was also

A Novel Approach of Retrofitting a Combined Cycle With Post Combustion CO2 Capture

Most state-of-the-art natural gas-fired combined cycle (NGCC) plants are triple-pressure reheat cycles with efficiencies close to 60%. However, with carbon capture and storage, the efficiency will be penalized by almost 10% units. To limit the energy consumption for a carbon capture NGCC plant, exhaust gas recirculation (EGR) is necessary. Utilizing EGR increases the CO2 content in the gas turbine
