A robust second order, shock-capturing numerical scheme for multi-dimensional special relativistic magnetohydrodynamics on computational domains with adaptive mesh refinement is presented. The base solver is a total variation diminishing Lax-Friedrichs scheme in a finite volume setting and is combined with a diffusive approach for controlling magnetic monopole errors. The consistency between th...

As the expansion of edge devices, such as local servers or even IoT (Internet Things) computing reforms data processing flow, engendering improvement in faster insights, improved response times and better bandwidth availability. However, industry encounters computational resource constraints machine learning on e.g., limitation memory power. To tackle this situation, we attempt to enhance flexi...

Generalizing the idea of viewing a digraph as a model of a linear map, we suggest a multi-variable analogue of a digraph, called a hydra, as a model of a multi-linear map. Walks in digraphs correspond to usual matrix multiplication while walks in hydras correspond to the tensor multiplication introduced by Robert Grone in 1987. By viewing matrix multiplication as a special case of this tensor m...

We consider an age-maturity structured model arising from a blood cell proliferation problem. This model is "hybrid", i.e., continuous in time and age but the maturity variable is discrete. This is due to the fact that we include the cell division marker carboxyfluorescein diacetate succinimidyl ester. We use our mathematical analysis in conjunction with experimental data taken from the divisio...

Comparative genomic in situ hybridization analysis of four cell lines derived from SV40 large T antigen-induced primitive neuroectodermal tumors of the rat revealed non-recurrent chromosomal copy number changes and DNA amplifications at chromosomal bands 2q34, 4q43qter and 15q12qter in cell lines TZ102, TZ103 and TZ107, respectively. Semi-quantitative PCR and western blot analysis demonstrated ...

In this work the issue of wave-induced flow structures that develop around a largediameter surface-piercing vertical circular cylinder is addressed. A strictly-linear wave case is considered and simulated numerically, solving the Euler equations in primitive variables, and the results are compared with those obtained from the corresponding close-form velocity-potential solution. Then, the swirl...

The sections show a high-grade malignancy with primitive – undifferentiated morphology, infiltrating dermis and subcutaneous soft tissues. This tumor has no particular pattern of growth or specific apparent line of differentiation. Cytologically it corresponds to primitive cells, some with cytoplasm including rhabdoid features. Focal areas show myxoid background and short spindle-cell morpholog...

In this paper we present a polynomial-time algorithm to solve the following problem: given a non-zero polynomial f e Q[X] in one variable with rational coefficients, find the decomposition of f into irreducible factors in Q[X]. It is well known that this is equivalent to factoring primitive polynomials feZ[X] into irreducible factors in Z[X]. Here we call f ~ Z[X] primitive if the greatest comm...

A multi-sensory discrete-continuous control concept has been developed to realize interactive basic skills for humanoid and mobile service robots. In the upper hierarchy level a discrete task control structure enables the flexible execution of primitive skill sequences. In the lower continuous level a suitable controller is chosen with control parameters adapted to the current primitive skill. ...
