A Continuous Double Auction (CDA) is a powerful auction mechanism used in online share trading. A CDA has many buyers and sellers continually exchanging items. Implementing an online CDA in software is more complicated than a regular online auction (such as eBay). This paper describes our experiences with implementing an online CDA. We present the model as an abstraction of the online share tra...

The Health Level 7 Clinic Document Architecture (CDA) is an XML-based document markup standard that specifies the hierarchical structure and semantics of “clinical documents” for the purpose of information exchange. In this research, issues arising with the design and implementation of a DB to support efficient retrieval from CDA documents and data mining for statistical analysis purposes are e...

A formal treatment to the privacy of concealed data aggregation (CDA) is given. While there exist a handful of constructions, rigorous security models and analyses for CDA are still lacking. Standard security notions for public key encryption schemes, including semantic security and indistinguishability against chosen ciphertext attacks, are refined to cover the multi-sender nature and aggregat...

Despite the saliency of raising critical thinking not only in ELT but also in other aspects of life, there is still lack of studies in this regard that need to be filled. Previous studies dealt with Faiclough’s model not that of van Dijk, and besides, they weren’t concerned about CDA effects on different proficiency levels. The present study, however, examined the impact of critical discourse a...

Since clinical document architecture (CDA) became an American National Standards Institute (ANSI)-approved health level seven (HL7) Standard, many countries have begun making an effort to make local standards conform to CDA. In order to make CDA compatible with the many different local standards existing in different countries, we designed a prototype model using HL7 CDA R2 with medical markup ...

PURPOSE The aims of this study were to characterize the concentration-time course of cladribine (CdA) and its main metabolite 2-chloroadenine (CAde), estimate interindividual variability in pharmacokinetics (PK), and identify covariates explaining variability in the PK of CdA. METHODS This population PK analysis was based on the combined dataset from four clinical studies in patients with mul...

BACKGROUND Clinical trials apply standards approved by regulatory agencies for Electronic Data Capture (EDC). Operational Data Model (ODM) from Clinical Data Interchange Standards Consortium (CDISC) is commonly used. Electronic Health Record (EHR) systems for patient care predominantly apply HL7 standards, specifically Clinical Document Architecture (CDA). In recent years more and more patient ...
