The main purpose of the presentation is to outline some alternative approaches on how a superlative annual consumer price index could be constructed using the monthly price information that is presently collected by statistical agencies. The first issue that must be addressed is: how should the monthly price information at the lowest level of aggregation be aggregated up (over months) to form a...

Medical literature searches have become more complex because of the increasing amount of published material and the multiple available databases indexing those publications. Although newly graduated physicians may have received some training in literature searching as part of a medical school curriculum, most clinicians have received no formal training in this skill. In today's world of evidenc...

OBJECTIVES While researchers are increasingly recognizing the importance of adjusting waist circumference (WC) for height, no standard has yet been established. In this study we contrast three standard methods for indexing WC by height (using height, root-height and height-squared) via comparisons with age-specific optimal indices. STUDY DESIGN AND SETTING Measurements from 722 male and 746 f...

The rapid advance of DNA sequencing technologies has yielded databases of thousands of genomes. To search and index these databases effectively, it is important that we take advantage of the similarity between those genomes. Several authors have recently suggested searching or indexing only one reference genome and the parts of the other genomes where they differ. In this paper, we survey the 2...

To support “Database as a service” (DaaS) in the cloud, the database system is expected to provide similar functionalities as in centralized DBMS such as efficient processing of ad hoc queries. The system must therefore support DBMS-like indexes, possibly a few indexes for each table to provide fast location of data distributed over the network. In such a distributed environment, the indexes ha...

The index selection problem (ISP) concerns the selection of an appropriate indexes set to minimize the total cost for a given workload under storage constraint. Since the ISP has been proven to be an NP-hard problem, most studies focus on heuristic algorithms to obtain approximate solutions. The problem becomes more difficult for indexes defined on multiple tables such as bitmap join indexes, s...

Signals of system functioning of different nature are presented in the parameter space (state-velocity-acceleration) as a trajectory of dynamic events. Such signals geometrization allows to reveal the hidden spatio-temporal correlation in dynamics of systems functioning. It is shown that the nature of relationship between the dynamic parameters of signal determines the natural cycle of sensor f...

This work focuses on combined scanning electron microscopy and energy dispersive X-ray analysis (SEM-EDX) applied to granular sludge used for biological treatment of high-strength wastewater effluents. Mineral precipitation is shown to occur in the core of microbial granules under different operating conditions. Three dairy wastewater effluents, from three different upflow anaerobic sludge blan...

The growing dimension and complexity of the available experimental data generating biological networks have increased the need for tools that help in categorizing nodes by their topological relevance. Here we present CentiScaPe, a Cytoscape app specifically designed to calculate centrality indexes used for the identification of the most important nodes in a network. CentiScaPe is a comprehensiv...

Background and Objectives: Although the anti-inflammatory effects of phytochemicals have been supported by several in vitro studies, their biological actions from regular diets are mixed. This study aimed to use dietary phytochemical index (DPI), as a food-based framework to assess dietary phytochemical intake and to understand its association with hs-CRP in a sample of Iranian women. Evaluatio...
