An overview on XML similarity: Background, current trends and future directions
2009
In recent years, XML has been established as a major means for information management, and has been broadly utilized for complex data representation (e.g. multimedia objects). Owing to an unparalleled increasing use of the XML standard, developing efficient techniques for comparing XML-based documents becomes essential in the database and information retrieval communities. In this paper, we provide an overview of XML similarity/comparison by presenting existing research related to XML similarity. We also detail the possible applications of XML comparison processes in various fields, ranging over data warehousing, data integration, classification/clustering and XML querying, and discuss some…
Extensible User-Based XML Grammar Matching
2009
International audience; XML grammar matching has found considerable interest recently due to the growing number of heterogeneous XML documents on the web and the increasing need to integrate, and consequently search and retrieve XML data originated from different data sources. In this paper, we provide an approach for automatic XML grammar matching and comparison aiming to minimize the amount of user effort required to perform the match task. We propose an open framework based on the concept of tree edit distance, integrating different matching criterions so as to capture XML grammar element semantic and syntactic similarities, cardinality and alternativeness constraints, as well as data-ty…
XCDL: an XML-oriented visual composition definition language
2010
International audience; XML data flow has reached beyond the world of computer science and has spread to other areas such as data communication, e-commerce and instant messaging. Therefore, manipulating this data by non expert programmers is becoming imperative. On one hand, Mashups have emerged a few years ago, providing users with visual tools for web data manipulation but not necessarily XML specific. Mashups have been leaning towards functional composition but no formal languages have yet been defined. On the other hand, visual languages for XML have been emerging since the standardization of XML, and mostly relying on querying XML data for extraction or structure transformations. These…
Patient documentation for the ultrasound laboratory
1991
The development of a PC based system for the storage of patient data in the echocardiography laboratory is described. Special design objectives were low cost and user friendliness, including an integrated special query language. After 3 years of use, the system stores 80000 diagnoses from 12000 patients without any relevant slowdown of response. Future developments concerning the communication between the database system and an echocardiographic sector scanner are discussed.
E-Learning in Pharmacology and Pharmacy
2011
Computer-based learning facilitates a shift from externally controlled to self-directed learning. Universities and other educational institutions are challenged by these developments and must react appropriately to meet the requirements of education. The term e-learning has been coined to describe a wide range of diverse learning and teaching strategies based on the use of electronic devices. Recently developed concepts in the science of education and learning provide appropriate frameworks for novel e-learning scenarios. The present review introduces strategies and concepts for the implementation of e-learning in academic and non-academic programs and gives an overview of current e-learnin…
Prescription drug use during pregnancy in France: a study from the national health insurance permanent sample.
2017
International audience; PurposeTo provide an up-to-date account of drug prescription during pregnancy in France from 2011 to 2014 using the permanent sample of the French national computerized healthcare database and with a focus on recommended supplementations, fetotoxic drugs and teratogenic drugs.MethodsAll pregnancies identified by the International Classification of Diseases, 10th Revision codes list in the hospitalization database, lasting more than 9 weeks of amenorrhea and whose delivery occurred between 01/01/2011 and 12/31/2014, were included. Drugs delivered between the trimester before and until the end of the pregnancy were included. Drug exposure prevalence was calculated for …
The impact of polypharmacy and drug interactions among the elderly population in Western Sicily, Italy.
2017
Aim: Primary endpoint was to report polypharmacy distribution in the general population vs ≥65 years old people and to examine the frequency of drug–drug interactions (DDIs) in the Health Local Unit of Palermo, Italy, in relationship with patients’ age. Methods: Drug prescription data for the year 2014 were extracted from the database of the Local Health Unit of Palermo Province, Italy. Patients were divided into five age groups (0–13, 14–64, 65–69, 70–74, and ≥75 year old). The detection of potential DDIs in polypharmacy profiles was performed with NavFarma software (Infologic srl, Padova, Italia), with DDI classification provided by tool Micromedex Drug Reax (Truven Health Analitics, Mich…
Patterns and trends in scientific research on generic drugs
2016
[Purpose]: The purpose of this study to investigate the evolution and current status of peer-reviewed publications concerning generic drugs during the past few decades. [Methods]: Scientific articles about generic drugs published until 2012 were retrieved through the PubMed/MEDLINE database, and a content analysis was performed. [Findings]: Our study revealed an increasing number of publications on generics since 1984. Statins, antiretroviral therapies, and antiepileptics, followed by immunosuppressants and antithrombotic agents, were the most common therapeutic drug categories. [Implications]: Almost 60% of the generics detailed in studies indexed in MEDLINE were acting on the cardiovascul…
A novel methodology for accelerating bitstream relocation in partially reconfigurable systems
2012
International audience; Xilinx Virtex FPGAs offer the possibility of Partial Reconfiguration (PR). Arbitrary tasks can be allocated and de-allocated onto FPGA without system interruption. However, mapping a task to any available PR region requires a unique partial bitstream for each partition, hence reducing memory storage requirements. In recent years, an interest on overcoming this problem has lead to the concept of Partial Bitstream Relocation (PBR). The principle is to perform bitstream modification to map it to different regions. However, PBR consumes scarce resources in hardware implementations, and introduces a prohibitive time overhead when done in software. In order to find the bes…
Trading off accuracy for efficiency by randomized greedy warping
2016
Dynamic Time Warping (DTW) is a widely used distance measure for time series data mining. Its quadratic complexity requires the application of various techniques (e.g. warping constraints, lower-bounds) for deployment in real-time scenarios. In this paper we propose a randomized greedy warping algorithm for finding similarity between time series instances. We show that the proposed algorithm outperforms the simple greedy approach and also provides very good time series similarity approximation consistently, as compared to DTW. We show that the Randomized Time Warping (RTW) can be used in place of DTW as a fast similarity approximation technique by trading some classification accuracy for ve…
