As the most recent video coding standard, High Efficiency Video Coding (HEVC) adopts various novel techniques, including a quad-tree based unit (CU) structure and additional angular modes used for intra encoding. These new techniques achieve notable improvement in efficiency at penalty of significant computational complexity increase. Thus, fast HEVC algorithm is highly desirable. In this paper...

The existence of outflow in the advection dominated accretion flows has been confirmed by both numerical simulations and observations. The outow models for ADAF have been investigated by several groups with a simple self similar solution. But this solution is inaccurate at the inner regions and can not explain the emitted spectrum of the flow; so, it is necessary to obtain a global solution for...

Right bundle branch block (RBBB) is usually considered almost unavoidable after repair of tetralogy of Fallot (TOF). By modifications of the standard technique, its frequency has been decreased to 32% in a series of 100 consecutive patients. These modifications are: (1) a very short right ventricular incision, avoiding the ventriculotomy-induced RBBB pattern; (2) an infundibular resection limit...

Several properties of atoms of block monoids are developed. We count the number of atoms of small cardinality. We also develop various properties of atoms of maximal cardinality (the Davenport constant). We use these properties to find new bounds on the Davenport constant both in general and for several important classes of groups. We also determine the Davenport constant (with computer assista...

Curvature has received increased attention as an important alternative to length based regularization in computer vision. In contrast to length, it preserves elongated structures and fine details. Existing approaches are either inefficient, or have low angular resolution and yield results with strong block artifacts. We derive a new model for computing squared curvature based on integral geomet...

We show that both analytic and numerical evidence points to the existence of a critical angle of h'60° –70° in viscous fingers and diffusion-limited aggregates growing in a wedge. The significance of this angle is that it is the typical angular spread of a major finger. For wedges with an angle larger than 2h , two fingers can coexist. Thus a finger with this angular spread is a kind of buildin...

Distances in cosmology are usually inferred from observed redshifts—an estimate that is dependent on the local peculiar motion—giving a distorted view of the three-dimensional structure and affecting basic observables such as the correlation function and power spectrum. We calculate the full nonlinear redshiftspace power spectrum for Gaussian fields, giving results for both the standard flat-sk...

I review the theory of angular momentum acquisition of galaxies by tidal torquing, the resulting angular momentum distribution, the angular momentum correlation function and discuss the implications of angular momentum alignments on weak lensing measurements: Starting from linear models for tidal torquing I summarise perturbative approaches and the results from n-body simulations of cosmic stru...
