Network proximity computations are among the most common operations in various data mining applications, including link prediction and collaborative filtering. A measure of network is Katz index, which has been shown to be best-performing path-based algorithms. With emergence very large databases, such become an important part query processing these databases. Consequently, significant effort d...

Predictions of missing links of incomplete networks, such as protein-protein interaction networks or very likely but not yet existent links in evolutionary networks like friendship networks in web society, can be considered as a guideline for further experiments or valuable information for web users. In this paper, we present a local path index to estimate the likelihood of the existence of a l...

UNLABELLED This study involved the development and performance assessment of a cultural adaptation of the Katz scale of independence in activities of daily living, translated into Portuguese in Brazil. Two translations and two back-translations of the items were analyzed by experts in order to decide on the final version. Operational equivalence was assessed in a pilot study. The reliability an...

This is a descriptive cross-sectional study. The sample consisted of 93 aged people, divided among four institutions in the municipality of Lamego (Portugal). The purpose of this study was to investigate the quality of life of the sample and the factors affecting it, and identify the degree of dependence in basic daily living activities. The data was collected using the following: i) a bio-rela...

In a previous lecture, we showed a zero-knowledge (ZK) proof system for the language of graph isomorphism. Our goal here is to show a ZK proof system for any language inNP . To do so, it suffices to show a ZK proof system Π for any NP-complete language L (note that graph isomorphism is not believed to be NP-complete); given such a Π and any L ′ ∈ NP , we then obtain a ZK proof for L by (1) redu...

PURPOSE Katz et al have published a standardized scoring system of hand diagrams for carpal tunnel syndrome. The purpose of this study was to quantitatively evaluate an alternative scoring of the hand diagram for detection of carpal tunnel syndrome. METHODS In a prospective study of 1,107 workers, 221 workers with hand symptoms completed hand diagrams and electrodiagnostic testing for carpal ...
