A first measurement is presented of the charge asymmetry in the hadronic final state from the hard interaction in deep-inelastic ep neutral current scattering at HERA. The measurement is performed in the range of negative squared four momentum transfer 100 < Q(2) < 8000 GeV2. The difference between the event normalised distributions of the scaled momentum, x(p), for positively and negatively charg

Based on previous results on linear predictors and Kalman filter, this paper will formulate multi-step-ahead multi-variate predictors for application in multi-step-ahead predictive control.

We report on a revisit in 2009 to sites where vegetation was recorded in 1967 and 1970 on Disko Island, West Greenland. Re-sampling of the same clones of the grass Phleum alpinum after 39 years showed complete stability in biometrics but dramatic earlier onset of various phenological stages that were not related to changes in population density. In a fell-field community, there was a net species l

We determined the proportion of butterfly species that occur as metapopulations with grasslands as the only habitat. We counted all butterflies in 19 semi-natural grassland patches in a forest-dominated landscape in southern Sweden over a 5-y period. Seven of the 44 butterfly species observed exhibited a metapopulation structure. The other species either use grassland mainly for adult feeding but

Popular Abstract in Swedish Bakgrund Uppskattningsvis har 34 miljoner människor världen över någon typ av demenssjukdom. Sjukdomarna leder till stort lidande för både patienter och anhöriga och beräknas kosta samhället 422 miljarder amerikanska dollar årligen. Den vanligaste demenssjukdomen är Alzheimers sjukdom och den utgör ca 60–70% av alla demenssjukdomar. Sjukdomarna blir allt vanligare och åBackground It is estimated that 34 million people suffer from dementia, costing society US$422 billion each year. Alzheimer’s disease (AD) is the most common dementia and the global prevalence is predicted to increase to over 100 million people by the year 2050, with the greatest increase in developing countries. Therefore, inexpensive and efficient instruments are required for investigation and e

There has been a significant rise in the number of patents originating from academic environments. However, current conceptualizations of academic patents provide a largely homogenous approach to define this entrepreneurial form of technology transfer. In this study we develop a novel categorization framework that identifies three subsets of academic patents which are conceptually distinct from ea

The emulsification process is primarily determined by the rate of fragmentation and coalescence of emulsion drops. However, there is presently no fast, reliable method for measuring these rates for pilot and production scale high pressure homogenizers. In this paper a method for simultaneous estimating fragmentation and coalescence is developed and tested based on the work of Hounslow and Ni (2004

Time spent waiting is frequently regarded as time wasted, and therefore as something to be avoided or at least minimized. In this article, however, waiting is viewed from an organizational perspective: delay and waiting are seen as integral to the strategic functioning of organizations, and to their handling of individual requests. Various kinds of waiting or intended organizational delays are des

Compact SPECT systems with cadmium zinc telluride (CZT) solid-state detectors with improved energy resolution and shorter acquisition times have recently been introduced. These systems have, however, different energy characteristics compared to NaI(Tl) crystal-based cameras; therefore, a need exists to develop new simulation models for these cameras. We modeled the charge transport within the CZT

The paper's target is the historically influential betting interpretation of subjective probabilities due to Ramsey and de Finetti. While there are several classical and well-known objections to this interpretation, the paper focuses on just one fundamental problem: There is a sense in which degrees of belief cannot be interpreted as betting rates. The reasons differ in different cases, but there'

The contribution's main objective is the treatment of non-classical nonlinear thermoelasticity based on the approach of Green and Naghdi within the context of the material force method. Material forces have proven to be well suited for the examination of defect mechanics and have become a very powerful and active research topic over the last decades. The numerical realization is based on finite el

Plasmid pLALA was constructed for glycerol or glycerol-3-phosphate inducible plasmid-borne gene expression in Bacillus subtilis and closely related Gram-positive bacteria. Gene expression using pLALA is based on anti-termination of transcription and involves the B. subtilis GlpP protein that in the presence of glycerol-3-phosphate acts as an anti-terminator protein by binding to the 5'-untranslate

Realistic Multiple-Input Multiple-Outout (MIMO) radio channel models are required in order to make fair system comparisons and to design proper signal processing algorithms using this technology. This technical report presents a full parameterization of the COST 2100 MIMO channel model for peer-to-peer communication in the 300 MHz band. Measurements were carried out in a semi-rural and suburban en

We have studied the ultrathin aluminum oxide film on NiAl(110) by a combination of high-resolution core-level spectroscopy and density functional theory calculations. Energy-dependent core-level data from the O 1s and Al 2p levels allows for a distinction between oxygen and aluminum atoms residing at the surface or inside the aluminum oxide film. A comparison to calculated core-level binding energ

Efter införande av Hälsoval Skåne har andelen av befolkningen som besökt allmänläkare ökat, liksom antalet besök per invånare. Ökningarna är överlag måttliga, med undantag för äldre män med lägre inkomst, där ökningen är större.Det finns också en minskning av besöken till övriga specialistläkare så att det totala antalet läkarbesök per invånare minskat i vissa grupper. Färre besök hos övriga speci

Diabetic maculopathy and retinal detachment, especially involving macula, are potentially sight-threatening conditions. Previous evaluations of retinal function, and treatment of these conditions have been subjective methods depending on the examiner or the collaboration with the examined patient. Retinal structure has been based on the subjective evaluation of the ophthalmologist. Development of

Background: The global gene regulator Special AT-rich sequence-binding protein1 (SATB1) has been reported to reprogramme tumour cells into a more malignant phenotype and associate with poor clinical outcome in several cancer forms. In this study, we investigated the molecular correlates and prognostic impact of SATB1 expression in human epithelial ovarian cancer (EOC). Findings: Immunohistochemica

Abstract in German Die Parkinson-Krankheit („Parkinson”) ist eine neurodegenerative Erkrankung die durch den Verlust von Dopamin-produzierenden Nervenzellen in der Substantia Nigra und daraus resultierenden, typischen motorischen Symptomen gekennzeichnet ist. Die Standardbehandlung für Parkinson ist die Gabe von L-DOPA, zum Zweck der Ersetzung des verlorengegangen Dopamins. Eine Langzeittherapie mParkinson’s disease (PD) is a neurodegenerative disorder, characterized by the loss of dopamine (DA) producing neurons in the substantia nigra pars compacta (SNc), resulting in typical motor symptoms. DA replacement with L-DOPA is the standard therapy for PD. However, with treatment duration many patients face the severe treatment complication of L-DOPA-induced dyskinesia (LID), constituting in ab

Beliefs in signals that reveal lies and truths are widespread. It is shown that such beliefs may be exploited strategically in signaling games of pure conflict of interest. Truth and lie detection is modeled by signals perceived by the receiver that are emitted with a probability contingent on the truth value of the sender's message. Truth or lie detection of this kind always shrinks the equilibri
