Mitkov and Ha (2003) et al. (2006) offered an alternative to the lengthy demanding activity of developing multiple-choice test items by proposing NLP-based methodology for construction from instructive texts such as textbook chapters encyclopaedia entries. One interesting research questions which emerged during these projects was how better quality distractors could automatically be chosen. This paper reports results a study seeking establish similarity measures generate tests. Similarity...

TGF-beta and Ras regulate epithelial-mesenchymal transition (EMT), a process that contributes to tumor invasion metastasis. The interaction of these pathways in EMT is still poorly understood. Here, we show induces but limits cell whereas hyperactivated (H-RasV12) does not cause enhances invasion, alleviating the inhibitory effect TGF-beta. disrupts junctions tropomyosin-mediated actin fibers matrix adhesion. Smad transcription factors mediate both steps TGF-beta-induced RasV12 inhibits...

The Electric Vehicles (EV) realize the clean and environment friendly traffic. It is true if EV-s fuelled by renewable based electricity. One viable energy source small medium scale PV systems. This paper investigates different - EV charger combinations. concentrated load generated chargers can overload existing network or huge developments are necessary. We found that daytime garage of officers employees a possible place where to charge cars during work time. If we do not want cause an...

The large number of tweets generated daily is providing decision makers with means to obtain insights into recent events around the globe in near real-time. main barrier for extracting such impossibility manual inspection a diverse and dynamic amount information. This p roblem has attracted attention industry research communities, resulting algorithms automatic extraction semantics linking them machine readable resources. While tweet shallowly comparable any other textual content, it hides...

Topic classification (TC) of short text messages offers an effective and fast way to reveal events happening around the world ranging from those related Disaster (e.g. Sandy hurricane) Violence Egypt revolution). Previous approaches TC have mostly focused on exploiting individual knowledge sources (KS) DBpedia or Freebase) without considering graph structures that surround concepts present in KSs when detecting topics Tweets. In this paper we introduce a novel approach for harnessing such...

PV based large scale energy generation has spread significantly. In spite of similar technical parameters the amount yearly produced may differ by notable percents. It results from operation solar trackers and also different spectral behavior panel types. this paper we introduce a novel on site sensitivity measurement method. The characteristic is recalculated separate power maximum measurements, where measurements are made spectrally natural irradiation (sunrise, noon, foggy, cloudy, etc.).

Influence of aging factors - or in other words, age the photovoltaic panels on electric current-voltage characteristics, power generation efficiency and position operating points were experimentally investigated. For measurements artificial light sources (so-called sun simulator device) self-developed semi-automatic data recorder system used. Data plotted by in-house developed MatLab routines results analyzed as well.

U-I characteristics - or electric power as function of electrical voltage current a solar panel (PV cell panel) gives important information for developers, engineers and users. From this reason to get plot characterization the plays role at tests. In paper new easy experimental method measurement (indirectly measured data) PV cells will be introduced. The idea describes simple, fast reliable way how properties in laboratory university using basic tools.

Uroplakin Ib is a structural protein on the surface of urothelial cells. Expression uroplakin mRNA reduced or absent in many transitional cell carcinomas (TCCs) but molecular mechanisms underlying loss expression remain to be determined. Analysis promoter identified weak CpG island spanning proximal promoter, exon 1, and beginning intron 1. This study examined hypothesis that methylation this regulates expression. levels were determined by reverse transcription polymerase chain reaction was...

A model has been developed for the simulation of Central-European electricity market forecast next 5-10-15 years. This simulator simulates trade flows that are not equal with physical flows. In this paper some scenarios introduced: border capacity change, cross price load and generation changes. The is capable to calculate long term prices equilibrium in coupled market. other operational mode course daily flow can be simulated. engine Matlab environment optimization toolbox, preparation made...
