Retinitis pigmentosa (RP) relates to a group of hereditary neurodegenerative diseases of the retina. On the cellular level, RP results in the primary death of rod photoreceptors, caused by rod-specific mutations, followed by a secondary degeneration of genetically normal cones. Different mechanisms may influence the spread of cell death from one photoreceptor type to the other. As one of these ...

The present study is concerned with measuring and simulating soot formation and combustion in turbulent liquid fuel spray flames. Soot concentrations inside the combustor are measured by filter paper technique. The simulation is based on the solution of the fully-coupled conservation equations for turbulent flow, chemical species kinetic modeling, fuel droplet evaporation and combustion and...

The paper presents novel ideas on spatial reasoning by considering shape and size of spatial entities and focuses on extension of conventional models: Cone-Shaped and Minimum Boundary Rectangle (MBR). Firstly, it goes on the use of how well MBR features fixed to cone-shaped model considering the relative extension of the spatial entities. This suggests the further possibility and the quality of...

PURPOSE To analyze cone and rod phototransduction parameters from ERG a-waves in patients with RP and to determine the relationships among these parameters, age, and mode of inheritance. METHODS Sets of four white flashes (3.2-4.4 log scotopic troland [scot td-s]) were presented in the dark. The same stimuli were later presented against a rod-saturating background and the generated cone a-wav...

The prediction of liquefaction potential of soil due to an earthquake is an essential task in Civil Engineering. The decision tree is a tree structure consisting of internal and terminal nodes which process the data to ultimately yield a classification. C4.5 is a known algorithm widely used to design decision trees. In this algorithm, a pruning process is carried out to solve the problem of the...

S are introduced to N2 and CO in general chemistry, and their prominence continues in inorganic chemistry 3 and physical chemistry. However, their isoelectronic relative, BF, is much less considered. Together, this trio of diatomic molecules comprises a series that superbly exemplifies numerous bonding and chemical trends. The changes in bonding lead to three molecules that behave very differen...

In this paper, we define the almost uniform convergence and the almost everywhere convergence for cone-valued functions with respect to an operator valued measure. We prove the Egoroff theorem for Pvalued functions and operator valued measure θ : R → L(P, Q), where R is a σ-ring of subsets of X≠ ∅, (P, V) is a quasi-full locally convex cone and (Q, W) is a locally ...

We present a technique for the dynamic annotation of three-dimensional objects in interactive virtual environments. Annotations represent textual or symbolic descriptions providing explanatory or thematic information associated with scene objects. In contrast to techniques that treat annotations as two-dimensional view-plane elements, our technique models annotations as separate three-dimension...
