Organic bulk heterojunction (BHJ) solar cells offer a viable source of solar energy. Structural organization is crucial in BHJ cells but hard to achieve and assess due to limitations in experimental methodology. Quantum chemical methods have here been used to gain further insight into the geometric and optical properties of a promising light-harvesting polymer, poly[2,3-bis(3-octyloxyphenyl)quinox

We study bankruptcy problems where the estate and the claims have stochastic values and we allow these values to be correlated. We associate a transferable utility game with uncertainty to a stochastic bankruptcy problem and use the Weak Sequential Core as a solution concept for such games. We test the stability of a number of well known division rules in this stochastic setting and find that all

The equations of motion for a beam are derived from the three-dimensional continuum mechanical point of view. The kinematics involve bending, torsion and shearing as well as cross-sectional displacements. The transplacement of the beam from an arbitrary curved reference placement is considered. For slender beams so called tubular coordinates may be used as global coordinates in the reference place

A multi-scale hydroclimatic study of runoff generation in the Athabasca River watershed located in western Canada is presented. Mann-Kendall trend detection tests performed on hydrometric data for the lower Athabasca River (LAR) revealed predominantly significant (p

Oligomers of the amyloid-beta peptide (A beta) are thought to be the most toxic form of A beta and are linked to the development of Alzheimer's disease (AD). Here, we used a flow cytometric approach for the detection and assessment of oligomers in cerebrospinal fluid (CSF) from AD patients and other neurological disorders. 30 CSF samples from patients suffering from AD (n=14), non-demented control

Unlike Knut Wicksell, Eli Heckscher did not believe the time had arrived for “managed money” to replace the gold standard after World War I. The war had shown that only a gold standard could bind the central bank to a time-consistent policy with reasonable price stability. Heckscher likened the problem of reinstating the gold standard to “Belling the cat” in Aesop’s fable. When the international g

We have investigated the temperature induced micelle-to-vesicle transition in a binary non-ionic surfactant/water system, for which the spontaneous curvature decreases with increasing temperature. Temperature jumps with variable rate were performed in a microwave oven, from a micellar phase at 5 ◦C to a lamellar phase region at 35 ◦C, passing a liquid-liquid two phase region where dilute and conce

The CADF test of Pesaran (A Simple Panel Unit Root Test in Presence of Cross-Section Dependence, Journal of Applied Econometrics 22, 265–312, 2007) are among the most popular univariate tests for cross-section correlated panels around. Yet, the existing asymptotic analysis of this test statistic is limited to a model in which the errors are assumed to follow a simple AR(1) structure with homogenou

A search for the b (b) over bar decay of the Standard Model Higgs boson is performed with the ATLAS experiment using the full dataset recorded at the LHC in Run 1. The integrated luminosities used are 4.7 and 20.3 fb(-1) from pp collisions at root s = 7 and 8 TeV, respectively. The processes considered are associated (WIZ)H production, where W -> e nu/mu nu, Z -> ee/mu mu, and Z -> nu nu. The obse

Introduction. Anti-neutrophil cytoplasmic antibodies specific for bactericidal/permeability-increasing protein (BPI-ANCA) are frequent in CF patients and mainly develop in response to infection with Pseudomonas aeruginosa. It is not known to what extent BPI-ANCA correlates to prognosis. Objectives. To evaluate the prognostic value of IgA-BPI-ANCA, measured at the beginning of the study, for transp

In the framework of the multiconfiguration Dirac-Hartree-Fock method, we investigate the transition properties of four excited states in the 2p(5)3s configuration of neutral neon. The electron correlation effects are taken into account systematically by using the active space approach. The effect of higher-order correlation on fine structures is shown. We also study the influence of the Breit inte

pH, salinity and nutrient conditions are major determinants of microbial biomass, activity and community composition; all being hypothesized to favour bacterial over fungal activity. Soils from Pravaranagar (India), having high nutrient content and high pH (pH(w) 7.4-8.8), with sometimes increased salinity, were thus expected to have high bacterial/fungal ratios. Twelve soils were characterized fo

Frequent use of pornography has not been sufficiently studied before. In a Swedish survey 2015 male students aged 18 years participated. A group of frequent users of pornography (N = 200, 10.5%) were studied with respect to background and psychosocial correlates. The frequent users had a more positive attitude to pornography, were more often “turned on” viewing pornography and viewed more often ad

Creatinine-based equations to estimate glomerular filtration rate (GFR) are increasingly used in radiological practice and in studies on contrast medium-induced acute kidney injury (CIAKI). Their use is recommended in guidelines and contrast medium textbooks to identify patients at risk of CIAKI or nephrogenic systemic fibrosis. There is also an increased interest in cystatin C-based equations. Ad

In this paper we consider a one-warehouse N-retailer inventory system characterized by access to real-time point-of-sale data, and a time based dispatching and shipment consolidation policy at the warehouse. More precisely, inventory is reviewed continuously, while a consolidated shipment (for example, a truck) to all retailers is dispatched from the warehouse at regular time intervals. The focus

BACKGROUND: -Ethnic differences in cardiac arrhythmia incidence have been reported, with a particularly high incidence of sudden cardiac death (SCD) and low incidence of atrial fibrillation in individuals of African ancestry. We tested the hypotheses that African ancestry and common genetic variants are associated with prolonged duration of cardiac repolarization, a central pathophysiological dete

Since the end of the Cold War, Western powers have frequently used sanctions to fight declining levels of democracy and human rights violations abroad. However, some of the world’s most repressive autocracies have never been subjected to sanctions, while other more competitive authoritarian regimes have been exposed to repeated sanction episodes. In this article, we concentrate on the cost–benefit

This work presents an event-based control structure using the generalized predictive control (GPC) algorithm with actuator deadband. The main objective of this work is to limit the number of controlled system updates. In this approach, the controlled process is sampled with a constant sampling time and is updated in an asynchronous way that depends on the obtained control signal value. To achieve
