Purpose To evaluate the global trends in health burden of people visually impaired from cataract in terms of disability-adjusted life years (DALY) and its correlations with national levels of socioeconomic development. Methods Global, regional, and national DALY numbers, crude rate, and age-standardized rate of cataract vision loss by age and sex were obtained from the database of the Global ...

In order to facilitate efficient query processing, the information contained in data warehouses is typically stored as a set of materialized views. Deciding which views to materialize represent a challenge in order to minimize view maintenance and query processing costs. Some existing approaches are applicable only for small problems, which are far from reality. In this paper we introduce a new...

SUl\l~IARY Repairing embedded memories (e-memories) on an advanced system-on-chip (SOC) product is a key technique used to improve product yield. However. increasing the die area of SOC products equipped with various types of e-memories on the die is an issue. A fuse scheme can be used to resolve this issue. However. several fuse schemes that have been proposed to decrease the die area result i...

With the aim of studying the contamination of soils with eggs of Toxocara spp. in an arid area in the central-western region of Argentina, 76 soil samples were collected from 18 towns belonging to six provinces of central-western Argentina. They were processed by the centrifugal flotation method. No eggs of Toxocara spp. were found. It can be concluded that the negative results are directly rel...

In the recent years, the software product lines paradigm has gained interest in both industry and academia. As in traditional software development, the concept of quality is crucial for the success of software product line practices and both functional and nonfunctional characteristics must be involved in the development process in order to achieve a high quality software product line. Therefor...

This paper designs and analyzes a quantum algorithm to solve a system of m quadratic equations in n variables over a finite field Fq. In the case m = n and q = 2, under standard assumptions, the algorithm takes time 2 on a mesh-connected computer of area 2, where t ≈ 0.45743 and a ≈ 0.01467. The area-time product has asymptotic exponent t+ a ≈ 0.47210. For comparison, the area-time product of G...

It is well known that there exist nonlinear statistical regularities in natural images. Existing approaches for capturing such regularities always model the image intensities by assuming a parameterized distribution for the intensities and learn the parameters. In the letter, we propose to model the outer product of image intensities by assuming a gaussian distribution for it. A two-layer struc...
