Injection and transport properties of fast electrons in ultraintense laser-solid interactions

Fast electron injection and transport in solid foils irradiated by sub-picosecond-duration laser pulses with peak intensity equal to 4 x 10(20)W/cm(2) is investigated experimentally and via 3D simulations. The simulations are performed using a hybrid-particle-in-cell (PIC) code for a range of fast electron beam injection conditions, with and without inclusion of self-generated resistive magnetic f

In situ determination of N-2 broadening coefficients in flames for rotational CARS thermometry

Total N-2 S-branch broadening coefficients have been measured in situ as a function of radial position in a highly sooting ethylene diffusion flame by the use of time-resolved dual-broadband picosecond pure rotational CARS (RCARS). Time-domain measurements of the J-dependent N-2 rotational coherence decays in the flame were used to determine the broadening coefficients, and these coefficients were

Urostomy and health-related quality of life in patients with lower urinary tract dysfunction

Objective. Urinary diversion may be an option in patients with disabling lower urinary tract dysfunction (DLUTD), refractory to conservative and minor invasive treatment. The aim of this study was to evaluate whether urostomy improves quality of life and cost of surgery, in terms of complications, loss of kidney function and hospital stay, in these patients. Material and methods. This prospective

Pion, Kaon, and Proton Production in Central Pb-Pb Collisions at root s(NN)=2.76 TeV

In this Letter we report the first results on pi(+/-), K-+/-, p, and (p) over bar production at midrapidity (vertical bar y vertical bar < 0.5) in central Pb-Pb collisions at root s(NN) = 2.76 TeV, measured by the ALICE experiment at the LHC. The p(T) distributions and yields are compared to previous results at root s(NN) = 200 GeV and expectations from hydrodynamic and thermal models. The spectra

Quantification of microscopic diffusion anisotropy disentangles effects of orientation dispersion from microstructure: Applications in healthy volunteers and in brain tumors

The anisotropy of water diffusion in brain tissue is affected by both disease and development. This change can be detected using diffusion MRI and is often quantified by the fractional anisotropy (FA) derived from diffusion tensor imaging (DTI). Although FA is sensitive to anisotropic cell structures, such as axons, it is also sensitive to their orientation dispersion. This is a major limitation t

Interference effects in two-color high-order harmonic generation

We study high-order harmonic generation in argon driven by an intense 800 nm laser field and a small fraction of its second harmonic. The intensity and divergence of the emitted even and odd harmonics are strongly modulated as a function of the relative delay between the two fields. We provide a detailed analysis of the underlying interference effects. The interference changes drastically when app

Evaluation of 11 terrestrial carbon-nitrogen cycle models against observations from two temperate Free-Air CO2 Enrichment studies

We analysed the responses of 11 ecosystem models to elevated atmospheric [CO2] (eCO(2)) at two temperate forest ecosystems (Duke and Oak Ridge National Laboratory (ORNL) Free-Air CO2 Enrichment (FACE) experiments) to test alternative representations of carbon (C)-nitrogen (N) cycle processes. We decomposed the model responses into component processes affecting the response to eCO(2) and confronted

Prevalence of older people with intellectual disability in Sweden: a spatial epidemiological analysis.

The expected increase in longevity of individuals with intellectual disabilities (ID) in many countries of the world is a direct result of medical and social advances, which have also extended the longevity of the general population. It is important to assess the need for social services for people with ID across different administrative levels to ensure sufficient resources are allocated to where

Melanosomes and ancient coloration re-examined: A response to Vinther 2015 (DOI 10.1002/bies.201500018).

Round to elongate microbodies associated with fossil vertebrate soft tissues were interpreted as microbial traces until 2008, when they were re-described as remnant melanosomes - intracellular, pigment-containing eukaryotic organelles. Since then, multiple claims for melanosome preservation and inferences of organismal color, behavior, and physiology have been advanced, based upon the shape and si

Sepsis-induced leukocyte adhesion in the pulmonary microvasculature in vivo is mediated by CD11a andCD11b.

Leukocyte accumulation is a rate-limiting step in inflammatory lung injury. The aim of this study was to define the role of CD11a/CD18 and CD11b/CD18 in sepsis-induced leukocyte rolling and adhesion in lung arterioles, capillaries and venules in male C57BL/6 mice using intravital fluorescence microscopy. Cecal ligation and puncture (CLP) markedly increased leukocyte rolling in arterioles and venul

Validation of the Distress Thermometer in a Swedish population of oncology patients; accuracy of changes during six months

Purpose: To validate the Swedish version of the Distress Thermometer (DT) against the Hospital Anxiety and Depression Scale (HADS) for screening of distress and to explore how well DT measures changes of distress during six months in a population of heterogeneous oncology patients. Methods: The DT was translated into Swedish according to the forward- and back-translation procedure. HADS total scor

Nomenclature of members of Hieracium sect. Alpestria, Foliosa and Prenanthoidea (Asteraceae) reported from Sweden

Alpestria (including the ‘Semidovrensia group’), Foliosa and Prenanthoidea and reported from Sweden have been compiled from the literature and herbaria and all uses have been indexed. Based on this synopsis, the nomenclatural validity and legitimacy of the names are analysed. In total, the use of 75, 62 and 27 names is documented for the three sections, re

Carbon dioxide degassing in fresh and saline water. II: Degassing performance of an air-lift

A study was undertaken to measure the efficiency with which carbon dioxide was stripped from freshwater (0 parts per thousand) and saline water (35 parts per thousand NaCl) passing through an air-lift at 15 degrees C. The air-lift was constructed of 50 mm (OD) PVC pipe submerged 95 cm in a tank, had an adjustable air injection rate, and could be adjusted to three lifting heights: 11,16 and 25 cm.

Parameter Selection for Real-Time Controllers in Resource-Constrained Systems

Inresource-constrained systems, the interference generated by the concurrent execution of multiple controller tasks leads to extra delay and jitter, which degrade control performance and may even jeopardize the stability of the controlled system. This work presents a general methodology that integrates control issues and real-time schedulability analysis to improve the control performance in embed

Variability of carbon monoxide and carbon dioxide apparent quantum yield spectra in three coastal estuaries of the South Atlantic Bight

The photochemical oxidation of oceanic dissolved organic carbon (DOC) to carbon monoxide (CO) and carbon dioxide (CO2) has been estimated to be a significant process with global photoproduction transforming petagrams of DOC to inorganic carbon annually. To further quantify the importance of these two photoproducts in coastal DOC cycling, 38 paired apparent quantum yield (AQY) spectra for CO and CO

Rate-Control Drugs Affect Variability and Irregularity Measures of RR Intervals in Patients with Permanent Atrial Fibrillation

Heart Rate Variability and Irregularity During AF IntroductionIrregularity measures have been suggested as risk indicators in patients with atrial fibrillation (AF); however, it is not known to what extent they are affected by commonly used rate-control drugs. We aimed at evaluating the effect of metoprolol, carvedilol, diltiazem, and verapamil on the variability and irregularity of the ventricula

Epigenetic Responsibility

The purpose of this article is to argue for a position holding that epigenetic responsibility primarily should be a political and not an individual responsibility. Epigenetic is a rapidly growing research field studying regulations of gene expression that do not change the DNA sequence. Knowledge about these mechanisms is still uncertain in many respects, but main presumptions are that they are tr

Microglial Markers are Elevated in the Prodromal Phase of Alzheimer's Disease and Vascular Dementia

Microglia manage immunosurveillance and mediate inflammation, both suggested to be important in Alzheimer's disease (AD). The aim of this study was to investigate if microglial markers could differentiate, firstly between AD and controls, and secondly between stable mild cognitive impairment (MCI) and those progressing to AD and vascular dementia (VaD). Furthermore, we investigated if these marker
