Large-scale astrophysical systems are non-extensive due to their long-range force of gravity. Here we show an approach toward the statistical mechanics of such self-gravitating systems (SGS). This is a generalization of the standard statistical mechanics based on the new definition of entropy; Tsallis statistical mechanics. Developing the composition of entropy and the generalized Euler relatio...

The paper adopts the Conjectural Variation model for investigating firms’ strategic behaviors in the wholesale electricity market. The aim of the proposed approach is providing market actors with a tool able to simulate the oligopolistic market models. The tool, utilized by a Generating Company (GenCo), permits to foresee the rivals’ behaviors and builds the suitable supply bid curve for its ow...

This critical review examines the effect of AAC assisted device screen layout on the ability of preschool children to access vocabulary. Specifically, this review compares the success of young children when using a speech generating device containing either a traditional grid organizational display, where vocabulary items are organized in a square grid pattern of discrete icons, or a Visual Sce...

In this paper, the service guaranteed scheduling model was proposed for the MPMS switching fabric. Firstly, the service distribution characteristic of each cell flow was analyzed in the MPMS switching fabric. Then, the service guaranteed distributed architecture was designed, and the scheduling model is proposed for demultiplexors, multiplexors, input switching units, middle switching units and...

With the advent of second-generation sequencing (SGS) technologies, deoxyribonucleic acid (DNA) sequencing machines have started to produce reads, named as “longer short reads”, which are much longer than previous generation reads, the so called “short reads”. Unfortunately, most of the existing read aligners do not scale well for those second-generation longer short reads. Moreover, many of th...

I first began working with a boy with juvenile Huntington's disease when he was 12 years old. He is now 17, and is still actively followed by our palliative care team. During those five years, there were many times when it was unclear whether or not he would have a tomorrow. At those times communication played a vital role. He now uses limited phonation and intonation and is not using speech; w...

The fight against HIV/AIDS poses enormous challenges worldwide, generating fears that success may be too difficult or even impossible to attain. Uganda has demonstrated that an early, consistent and multisectoral control strategy can reduce both the prevalence and the incidence of HIV infection. From only two AIDS cases in 1982, the epidemic in Uganda grew to a cumulative 2 million HIV infectio...

In this paper we present the problem of saturation of a given morphism in the database category DB, which is the base category for the functiorial semantics of the database schema mapping systems used in Data Integration theory. This phenomena appears in the case when we are using the Second-Order tuple-generating dependencies (SOtgd) with existentially quantified non-built-in functions, for th...

In this study, we used the NDVI time-series datasets to investigate variations in the starting dates of growing season (SGS) in China's cropland from 1983 to 2002. To do so, a smoothing algorithm based on an asymmetric Gaussian function was first performed on the NDVI dataset to minimize the effects of anomalous values caused by atmospheric haze and cloud contamination. The SGS of cropland was ...

Tupleand equality-generating dependencies have a wide range of applications in knowledge representation and databases, including ontological reasoning, data exchange, and data cleaning. In such settings, the chase is a central tool for many reasoning tasks. Since the chase evaluation might not terminate and it is undecidable whether it terminates, several termination criteria have been proposed...
