Towards an online-coupled chemistry-climate model: evaluation of trace gases and aerosols in COSMO-ART

The online-coupled, regional chemistry transport model COSMO-ART is evaluated for periods in all seasons against several measurement datasets to assess its ability to represent gaseous pollutants and ambient aerosol characteristics over the European domain. Measurements used in the comparison include long-term station observations, satellite and ground-based remote sensing products, and complex da

Exponentiation for products of Wilson lines within the generating function approach

We present the generating function approach to the perturbative exponentiation of correlators of a product of Wilson lines and loops. The exponentiated expression is presented in closed form as an algebraic function of correlators of known operators, which can be seen as a generating function for web diagrams. The expression is naturally split onto two parts: the exponentiation kernel, which accum

Accumulation capacitance of narrow band gap metal-oxide-semiconductor capacitors

We have investigated the accumulation capacitance-voltage characteristics for capacitors with narrow band gap materials using modeling and experiments. The capacitance for InAs and In0.53Ga0.47As capacitors with a HfO2 oxide layer has been calculated using atomistic tight-binding, effective mass, and semiclassical nonparabolic models. The simulations show that band structure effects have a strong

A process-based 222radon flux map for Europe and its comparison to long-term observations

Detailed (222)radon (Rn-222) flux maps are an essential pre-requisite for the use of radon in atmospheric transport studies. Here we present a high-resolution Rn-222 flux map for Europe, based on a parameterization of Rn-222 production and transport in the soil. The Rn-222 exhalation rate is parameterized based on soil properties, uranium content, and modelled soil moisture from two different land

Investigation on thermal performance of high temperature multilayer insulations for hypersonic vehicles under aerodynamic heating condition

Hypersonic vehicles have to withstand extremely high aerodynamic heating and pressure loads during the ascent and reentry stages. Multilayer thermal insulations have been widely designed in thermal protection systems to keep the temperature of underlying structure within an acceptable limit. In this study, a theoretical model is built combining radiation and conduction heat transfer in high temper

On the production of N-2(+) ions at the N 1s edge of the nitrogen molecule

The N-2(+) ion yield of the N-2 molecule has been measured at the N 1s -> Rydberg excitations. It displays Fano-type line shapes due to interference between direct outer-valence photoionization and participator decay of the core-excited Rydberg states. The N-2(+) ion yield is compared with the total intensity of the outer-valence photoelectron lines obtained recently with electron spectroscopy (Ki

Monitoring bisphenol A and its biodegradation in water using a fluorescent molecularly imprinted chemosensor.

In this paper, we present a simple and rapid method for monitoring bisphenol A (BPA) and its biodegradation in environmental water using a fluorescent molecularly imprinted polymer chemosensor (fMIPcs). A fluorescent molecularly imprinted polymer (fMIP) was first synthesized by precipitation polymerization method using BPA as template, dansyl methacrylate as functional monomer. Then a fMIPcs was c

Evaluating risk and vulnerability assessments: a study of the regional level in Sweden

Risk and Vulnerability Assessments (RVA) are performed on many levels of society by many different organisations. In the present paper we discuss how one can investigate if a system for RVA used in a country or a region fulfils its intended purpose. We show how the purpose of the Swedish system can be related to the actual form of the individual RVA documents. This is followed by a content analysi

Members of the emergency medical team may have difficulty diagnosing rapid atrial fibrillation in Wolff-Parkinson-White syndrome

Background: Atrial fibrillation (AF) in patients with Wolff-Parkinson-White (WPW) syndrome is potentially life-threatening as it may deteriorate into ventricular fibrillation. The aim of this study was to assess whether the emergency medical team members are able to diagnose AF with a rapid ventricular response due to the presence of atrioventricular bypass tract in WPW syndrome. Methods: The stud

Atherosclerosis aggravates ischemia/reperfusion injury in the gut and remote damage in the liver and the lung

Objective We investigated whether mesenteric ischemia/reperfusion (I/R)-associated gut injury and remote liver and lung damage are affected by prevalent atherosclerosis. Methods Mesenteric ischemia was induced in atherosclerotic ApoE-deficient (ApoE(-/-)) and control C57BL/6 mice by clamping the superior mesenteric artery for 30 min. Mesenteric microcirculatory dysfunction and leukocytic inflammat

Detection Of Gas Concentration By Correlation Spectroscopy Using A Multi-Wavelength Fiber Laser

A correlation spectroscopy (COSPEC) based on a multi-wavelength fiber laser is first proposed for the detection of gas concentration. The lasing wavelengths are selected to match several characteristic absorption peaks of the gas under test, and the gas concentration is easily measured by correlating it with the reference gas. The present method is immune from the instability of the light source a

Revisiting 'Weinberg's Choice': Classic Tensions in the Concept of Scientific Merit

Alvin Weinberg's classic and much debated two articles in Minerva, "Criteria for Scientific Choice" (1963) and "Criteria for Scientific Choice II - The Two Cultures" (1964), represent two of the first and most important attempts to create a meta-discourse about priority setting in science policy, and many of the points advanced remain relevant. The goal of this paper is to elaborate on the relevan

Association between the ABCC11 gene polymorphism and the expression of apolipoprotein D by the apocrine glands in axillary osmidrosis.

It has been suggested that the adenosine triphosphate‑binding cassette sub‑family C member 11 (ABCC11) gene polymorphism and apolipoprotein D (ApoD), an odor precursor carrier, may be important in the formation of axillary odor. To date, few studies have examined the potential correlation between these two factors. The present study aimed to investigate the association between a 538 G>A single‑nuc

Family environment and the malleability of cognitive ability: A Swedish national home-reared and adopted-away cosibling control study.

Cognitive ability strongly aggregates in families, and prior twin and adoption studies have suggested that this is the result of both genetic and environmental factors. In this study, we used a powerful design-home-reared and adopted-away cosibling controls-to investigate the role of the rearing environment in cognitive ability. We identified, from a complete national Swedish sample of male-male s

Maternal diet and aging alter the epigenetic control of a promoter-enhancer interaction at the Hnf4a gene in rat pancreatic islets

Environmental factors interact with the genome throughout life to determine gene expression and, consequently, tissue function and disease risk. One such factor that is known to play an important role in determining long-term metabolic health is diet during critical periods of development. Epigenetic regulation of gene expression has been implicated in mediating these programming effects of early

PBMC telomerase activity, but not leukocyte telomere length, correlates with hippocampal volume in major depression.

Accelerated cell aging, indexed in peripheral leukocytes by telomere shortness and in peripheral blood mononuclear cells (PBMCs) by telomerase activity, has been reported in several studies of major depressive disorder (MDD). However, the relevance of these peripheral measures for brain indices that are presumably more directly related to MDD pathophysiology is unknown. In this study, we explored

The influence of low and high pressure levels during negative pressure wound therapy on wound contraction and fluid evacuation.

BACKGROUND: Negative pressure wound therapy (NPWT) promotes healing by drainage of excessive fluid and debris and also by mechanical deformation of the wound edge tissue. The most commonly used negative pressure is -125 mmHg. However, this pressure may cause pain and ischemia, and the pressure often needs to be reduced. The aim of the present study was to examine wound contraction and fluid remova

A new galloping gait in an insect

An estimated three million insect species all walk using variations of the alternating tripod gait. At any one time, these animals hold one stable triangle of legs steady while swinging the opposite triangle forward. Here, we report the discovery that three different flightless desert dung beetles use an additional gallop-like gait, which has never been described in any insect before. Like a bound
