Frequency-hopping (FH) methods in the Orthogonal frequency division multiplexing access(OFDMA) system,which are to assign user-specific subcarrier to the active users, have been paid much attention to in the broadband wireless communication system. In this paper, we present a novel multiple access scheme, referred to as CDM-FH-OFDMA, which is the extension of FH-OFDMA with code division multipl...

This paper presents a method for classifying and structuring free-text clinical trial eligibility criteria using the OMOP Common Data Model (CDM). Our method was applied to eligibility criteria text available from the largest clinical trial repository ClinicalTrials.gov. Structurally complex criteria were simplified and rewritten as simpler sentences connected by logical operators: AND or OR. S...

This paper discusses one method of clustering a high dimensional dataset using dimensionality reduction and context dependency measures (CDM). First, the dataset is partitioned into a predefined number of clusters using CDM. Then, context dependency measures are combined with several dimensionality reduction techniques and for each choice the data set is clustered again. The results are combine...

It has been argued in light of concessions made at Bonn and Marrakech, the market for Clean Development Mechanism (CDM) projects will be small compared to greenhouse gas (GHG) emissions in developing countries and that it will be characterised by low demand and low prices. This paper examines these arguments in the context of India and the likely nature and extent of India’s involvement in CDM ...

This paper introduces the collective data mining (CDM), a new approach toward distributed data mining (DDM) from heterogeneous sites. It points out that naive approaches to distributed data analysis in a heterogeneous environment may face ambiguous situation and may lead to incorrect global data model. It also observes that any function can be expressed in a distributed fashion using a set of a...

Early photoionization of the intergalactic medium is discussed in a nearly model-independent way, in order to investigate whether early structures corresponding to rare Gaussian peaks in a CDM model can photoionize the intergalactic medium suuciently early to appreciably smooth out the microwave background uctuations. We conclude that this is indeed possible for a broad range of CDM normalizati...

BACKGROUND Concerns about increased mortality could question the role of COPD chronic disease management (CDM) programmes. We aimed at extending a recent Cochrane review to assess the effects of CDM on mortality in patients with COPD. METHODS Mortality data were available for 25 out of 29 trials identified in a COPD integrated care systematic review. Meta-analysis using random-effects models ...

We have studied, in vitro, proliferation induced by flagella (FE) and membrane (ME) antigenic fractions of T. cruzi epimastigotes, as well as their regulatory effect on the proliferative response to PPD (Protein Purified Derivative). Crude flagella as well as bands from Western blots of flagella and membrane of epimastigotes were tested. Crude flagella elicited higher proliferation in mononucle...

PURPOSE This study assessed the prevalence of physical and cognitive doping in recreational triathletes with two different randomized response models, that is, the Cheater Detection Model (CDM) and the Unrelated Question Model (UQM). Since both models have been employed in assessing doping, the major objective of this study was to investigate whether the estimates of these two models converge. ...
