Due to the rapid popularity of multi-core processors systems, the parallelization of XPath queries in shared memory multi-core systems has been studied gradually. Existing work developed some parallelization methods based on cost estimation and static mapping, which could be seen as a logical optimization of parallel query plan. However, static mapping may result in load imbalance that hurts th...

Human face pose estimation aims at estimating the gazing direction or head postures with 2D images. It gives some very important information such as communicative gestures, saliency detection and so on, which attracts plenty of attention recently. However, it is challenging because of complex background, various orientations and face appearance visibility. Therefore, a descriptive representatio...

We discuss various aspects of multi–instanton configurations in generic multi–cut matrix models. Explicit formulae are presented in the two–cut case and, in particular, we obtain general formulae for multi–instanton amplitudes in the one–cut matrix model case as a degeneration of the two–cut case. These formulae show that the instanton gas is ultra–dilute, due to the repulsion among the matrix ...

We review some of the techniques that lead to the effective medium representation of a three-dimensional (3D) periodic metamaterial. We consider a 3D lattice of lead telluride cubic resonators at mid-infrared (MIR) frequencies. Each cubic resonator is modeled with both an electric and a magnetic dipole, through a method called the dual dipole approximation. The electric and magnetic polarizabil...

We present block algorithms and their implementation for the parallelization of sub-cubic Gaussian elimination on shared memory architectures. Contrarily to the classical cubic algorithms in parallel numerical linear algebra, we focus here on recursive algorithms and coarse grain parallelization. Indeed, sub-cubic matrix arithmetic can only be achieved through recursive algorithms making coarse...

Purpose Determine which posterior uveal melanoma (PUM) size classification with three categories has the best prognostic discrimination. Methods Single-institution study of 424 consecutive patients with PUM. The tumor's largest basal diameter (LBD), smallest basal diameter (SBD), and thickness (TH) were estimated by fundus mapping and ultrasonography. Tumors were assigned to "small," "medium,...

Cubic fields (over the rationals) are the simplest non-Galois number fields and thus should be the ideal testing ground for most general “density” conjectures, such as the Cohen-Martinet heuristics. We present an efficient algorithm to generate them, up to a given discriminant bound, which we hope will prove a useful tool in their computational exploration. It all originates from the seminal pa...

In this article, we introduced an iterative scheme for finding a common element of the set of fixed points of a multi-valued hemicontractive-type mapping, the set of common solutions of a finite family of split equilibrium problems and the set of common solutions of a finite family of variational inequality problems in real Hilbert spaces. Moreover, the sequence generated by the proposed algori...

Until now we have considered the estimation of the value of a S/TRF at one point at the time, independently of the estimated values at other estimation points, i.e. a single-point mapping approach. The Bayesian Maximum Entropy (BME; Christakos, 1990, 1992) method offers a framework where the prediction of a S/TRF at several estimation points may be considered jointly, which is referred to as a ...
