The advent of collider energies to heavy–ion physics is leading to a profound change in the field. The new tools available, specially the access to the large transverse momentum part of the spectrum, allow for an unprecedented characterization of the high–density state created in such collisions. Accordingly, the traditional goal of producing a Quark-Gluon Plasma, the deconfined state of quarks...

In this paper, we propose a machine learning approach to solve the purchase prediction task launched by the Alibaba Group. In detail, we treat this task as a binary classification problem and explore five kinds of features to learn potential model of the influence of historical behaviors. These features include user quality, item quality, category quality, user-item interaction and user-categor...

With the aim of replacing the 20-year-old 2-D desktop metaphor with a more natural, intuitive to use, and immersive 3-D interface, we developed a prototype application that allows the dynamic exploration of document collections. Document metadata and relations between documents are visualized with the help of information visualization techniques. The general visualization and navigation metapho...

The precipitation of lithium dissolved in germanium crystals and the re-solution of the pre­ cipitates during heating has been studied by means of anomalous transmission of x-rays. The effec­ tive absorption coefficient depends sensitively on the spacial distribution of lithium interstitials, and is enhanced enormously if pair correlations increase, as is the case during clustering. On the basi...

The linear accelerator (linac) is a device that uses highfrequency electromagnetic waves to accelerate charged particles such as electrons to high energies through a linear tube. The high-energy electron beam can be used for treating superficial tumours, or it can be made to strike a target to produce x-rays for treating deep-seated tumours. In the majority of instances, the collimated beam eme...

We present electronic structure calculations for aluminium nanocontacts. Addressing the neck of the contact, we compare characteristic geometries to investigate the effects of the local aluminium coordination on the electronic states. We find that the Al 3pz states are very sensitive against modifications of the orbital overlap, which has serious consequences for the transport properties. Stret...

An E-CUSP (energy-convective upwind and split pressure) scheme is developed to solve the equations of magnetohydrodynamics. Fifth order WENO reconstructions are employed to calculate the fluxes in order to achieve high order spacial accuracy. A characteristic speed of sound by averaging the fast wave speed and the acoustic speed of sound is suggested to evaluate the Mach number, which will yiel...

We analyzed phonological and visual information processes of four Japanese dyslexic children between 710 years of age. None of them had disability in word retrieval and/or auditory memory. Two of them manifested lower score in phonological awareness tests while the others showed normal score. All children showed subnormal score in a visual cognitive test, a visuo-spacial constructional test, an...

Geographic information Systems (GIS) square measure an honest tool for group action completely different form of spacial info. Its provides fast analysis and correlation of assorted geographical contexts. This method planned collects the data and integration marine data kind satellite pictures. This method automatic collects the surface location of the target. The system gets all info concernin...

The third modification of the space-time geometry is considered. (The first modification is the spacial relativity, the second one is the general relativity.) After the third modification of the space-time geometry the motion of free particles become to be primordially stochastic (multivariant). This circumstance forces one to construct a multivariant dynamics. The multivariant dynamics is the ...
