A Jini-Based Solution for Electronic Prescriptions

In most countries today, handwritten, paper-based medical prescriptions are the norm.While efforts have been made in the past and are being made at present to migrate toward electronic dispensation of prescriptions, these have generally omitted to incorporate ubiquitous computing technology in their proposed solutions. In this paper, we focus on this issue and describe a Jini-based prototypical solution for electronic prescriptions, which allows for their wireless transmission to in-range pharmacies and the augmentation of the service levels rendered to the user, with, for instance, information about queue lengths and estimated waiting times being provided to the patients. Clinical and user evaluation revealed that there were high levels of agreement as regards the prototype’s effectiveness, ease of use, and usefulness

An agent-based DDM for high level architecture

The Data Distribution Management (DDM) service is one of the six services provided in the Runtime Infrastructure (RTI) of High Level Architecture (HLA). Its purpose is to perform data filtering and reduce irrelevant data communicated between federates. The two DDM schemes proposed for RTI, region based and grid based DDM, are oriented to send as little irrelevant data to subscribers as possible, but only manage to filter part of this information and some irrelevant data is still being communicated. Previously (G. Tan et al., 2000), we employed intelligent agents to perform data filtering in HLA, implemented an agent based DDM in RTI (ARTI) and compared it with the other two filtering mechanisms. The paper reports on additional experiments, results and analysis using two scenarios: the AWACS sensing aircraft simulation and the air traffic control simulation scenario. Experimental results show that compared with other mechanisms, the agent based approach communicates only relevant data and minimizes network communication, and is also comparable in terms of time efficiency. Some guidelines on when the agent based scheme can be used are also give

The role of phase dynamics in a stochastic model of a passively advected scalar

Collective synchronous motion of the phases is introduced in a model for the stochastic passive advection-diffusion of a scalar with external forcing. The model for the phase coupling dynamics follows the well known Kuramoto model paradigm of limit-cycle oscillators. The natural frequencies in the Kuramoto model are assumed to obey a given scale dependence through a dispersion relation of the drift-wave form $-\beta\frac{k}{1+k^2}$, where $\beta$ is a constant representing the typical strength of the gradient. The present aim is to study the importance of collective phase dynamics on the characteristic time evolution of the fluctuation energy and the formation of coherent structures. Our results show that the assumption of a fully stochastic phase state of turbulence is more relevant for high values of $\beta$, where we find that the energy spectrum follows a $k^{-7/2}$ scaling. Whereas for lower $\beta$ there is a significant difference between a-synchronised and synchronised phase states, and one could expect the formation of coherent modulations in the latter case.Comment: Accepted for publication in Physics of Plasma

Fisheries management of the green tiger prawn (Penaeus semisulcatus, De Haan,1844) in Bushehr waters, Persian Gulf

Stock assessment and the opening and closure seasons of the green tiger prawn were surveyed in Bushehr waters from July 2004 to September 2006. The study area encompassed Motaf area (27 degree 30' N" and 51 degree 30' E) to Daylam waters (30 degree 00' N and 50 degree 00' E) the northern part of the Iranian waters of the Persian Gulf. Assessment was conducted using 45 stations on 15 transect in water depths less than 10m, 10-20m and 20-30m. Sampling was done by bottom trawl net. Results showed that the shortest mean length of the prawn were 11.3, 11.8 and 11.9cm in the years 2004, 2005 and 2006, respectively. Also, the maximum catch per unit effort for the prawns in these years was foun d to be 10.8, 14.7 and 9.7kg per hour. At the opening of fishing season in the years 2004, 2005 and 2006, the CPUE of the prawn fishing launches were 100, 150 and 120kg per day. Based on length frequency of the green tiger prawn, the opening times of prawn fishing was proposed to be 22, 11 and 20, August of years 2004 , 2005 and 2006, respectively. Also, the closure times were derived from the shrimp commercial catch data and defined to be 25, 27 and 28 of September in 2004, 2005 and 2006, respectively. Investigation of the shrimp stock density in Bushehr waters shows that the green tiger prawns enter the fisheries areas from the southeastern parts of Bushehr waters. The Motaf, Nakhilou, Ras-e-khan and Mond River are the areas that green tiger prawn schools are first emerged in the Bushehr province waters

A theory of non-local linear drift wave transport

Transport events in turbulent tokamak plasmas often exhibit non-local or non-diffusive action at a distance features that so far have eluded a conclusive theoretical description. In this paper a theory of non-local transport is investigated through a Fokker-Planck equation with fractional velocity derivatives. A dispersion relation for density gradient driven linear drift modes is derived including the effects of the fractional velocity derivative in the Fokker-Planck equation. It is found that a small deviation (a few percent) from the Maxwellian distribution function alters the dispersion relation such that the growth rates are substantially increased and thereby may cause enhanced levels of transport.Comment: 22 pages, 2 figures.

Entanglement of Dirac fields in an expanding spacetime

We study the entanglement generated between Dirac modes in a 2-dimensional conformally flat Robertson-Walker universe. We find radical qualitative differences between the bosonic and fermionic entanglement generated by the expansion. The particular way in which fermionic fields get entangled encodes more information about the underlying space-time than the bosonic case, thereby allowing us to reconstruct the parameters of the history of the expansion. This highlights the importance of bosonic/fermionic statistics to account for relativistic effects on the entanglement of quantum fields.Comment: revtex4, 7 figures, I.F. previously published as Fuentes-Guridi and Fuentes-Schuller.

Comparison of plasma cardiac troponin I and cardiac enzymes in haemodialysis patients of Gorgan (South East of Iran)

The objectives of this study were to evaluate the effect of haemodialysis on plasma Cardiac Troponin I and cardiac enzymes before and after the dialysis process. Twenty two patients with Chronic Renal Failure (CRF) disease who were haemodialyzed at 5th Azar hospital of Gorgan Dialysis Center were recruited for this study (2005). The patients do not have coronary heart disease. Plasma cardiac enzymes showed no significant difference in the post dialysis group when compared with predialysis. Plasma levels of Cardiac Troponin I in 12 haemodialyzed patients were significantly increased in the postdialysis group when compared with predialysis, whereas plasma level of Cardiac Troponin I in 10 haemodialyzed patients were undetectable (less than 0.1 μg L⁻¹). The observation of meaningful increasing level of plasma Cardiac Troponin I in the haemodialyzed patients after the process of dialysis shows that Cardiac Troponin I is highly specific marker for Acute Myocardial Infarction (AMI) when compared with other cardiac enzymes and is particularly useful for detecting AMI in chronic renal failure and haemodialysis patients which can prevent sudden cardiovascular abnormality and sudden silent myocardial infarction in these patients. © 2007 Asian Network for Scientific Information
