Authors: Roselyn J. Preetha , Devaraj D. , Dash Subhransu Sekhar 
Published: November 2013

Abstract
Voltage stability is an important issue in the planning and operation of deregulated power systems. The voltage stability problems is a most challenging one for the system operators in deregulated power systems because of the intense use of transmission line capabilities and poor regulation in market environment. This article addresses the congestion management problem avoiding offline transmission capacity limits related to voltage stability by considering Voltage Security Constrained Optimal Power Flow (VSCOPF) problem in deregulated environment. This article presents the application of Multi Objective Differential Evolution (MODE) algorithm to solve the VSCOPF problem in new competitive power systems. The maximum of L-index of the load buses is taken as the indicator of voltage stability and is incorporated in the Optimal Power Flow (OPF) problem. The proposed method in hybrid power market which also gives solutions to voltage stability problems by considering the generation rescheduling cost and load shedding cost which relieves the congestion problem in deregulated environment. The buses for load shedding are selected based on the minimum eigen value of Jacobian with respect to the load shed. In the proposed approach, real power settings of generators in base case and contingency cases, generator bus voltage magnitudes, real and reactive power demands of selected load buses using sensitivity analysis are taken as the control variables and are represented as the combination of floating point numbers and integers. DE/randSF/1/bin strategy scheme of differential evolution with self-tuned parameter which employs binomial crossover and difference vector based mutation is used for the VSCOPF problem. A fuzzy based mechanism is employed to get the best compromise solution from the pareto front to aid the decision maker. The proposed VSCOPF planning model is implemented on IEEE 30-bus system, IEEE 57 bus practical system and IEEE 118 bus system. The pareto optimal front obtained from MODE is compared with reference pareto front and the best compromise solution for all the cases are obtained from fuzzy decision making strategy. The performance measures of proposed MODE in two test systems are calculated using suitable performance metrices. The simulation results show that the proposed approach provides considerable improvement in the congestion management by generation rescheduling and load shedding while enhancing the voltage stability in deregulated power system.
Control Volume Based Finite Element Method Study of Nano-fluid Natural Convection Heat Transfer in an Enclosure Between a Circular and a Sinusoidal Cylinder
Authors: Ghasemi E. , Soleimani S. , Bayat M. 
Published: November 2013

Abstract
In this study natural convection heat transfer in a cold outer circular enclosure containing a hot inner sinusoidal circular cylinder is investigated numerically using the Control Volume based Finite Element Method (CVFEM). The fluid in the enclosure is Cu-water nanofluid. Both circular enclosure and inner cylinder are maintained at constant temperature. The governing equations of fluid motion and heat transfer in their vorticity stream function form are used to simulate the fluid flow and heat transfer. The effective thermal conductivity and viscosity of nanofluid are calculated using the Maxwell–Garnetts (MG) and Brinkman models, respectively. The calculations were performed for different governing parameters such as the Rayleigh number, values of the number of undulations of the inner cylinder and nanoparticle volume fraction. The results show that for all Rayleigh number, increasing number of undulations causes the average Nusselt number to augment except that the average Nusselt number for N = 4 is greater than N = 5.
Hybrid Modulus-phase Synchronization of Hyperchaotic Complex Systems and its Application to Secure Communication
Authors: Wang Xingyuan , Luo Chao 
Published: November 2013

Abstract
In this article, a novel synchronization scheme is proposed to achieve hybrid modulus-phase synchronization in hyperchaotic complex systems, which means different synchronization schemes can be achieved simultaneously in modulus and phase spaces of complex systems. A general controller is designed to implement modified projective synchronization in modulus space and anti-synchronization in phase space. And the theoretical proof is given based on the Lyapunov stability theory. By utilizing the proposed synchronization scheme, an improved digital secure communication scheme is presented, the main advantage of which is to develop the transmission efficiency and reduce the design complexity. Numerical simulations are carried out to verify the effectiveness and feasibility of the proposed schemes.
A New Nonlinear Integrable Couplings of Solioton Hierarchy and its Hamiltonian Structure with Kronecker Product
Authors: Li Li , Yu Fajun 
Published: November 2013

Abstract
It is shown that the Kronecker product can be applied to construct new nonlinear integrable coupling system of soliton equation hierarchy in this paper. A direct application to the KN spectral problem leads to a novel KN soliton equation hierarchy of nonlinear integrable coupling system, which is different from any one obtained before. Furthermore, we present the Hamiltonian structures of nonlinear integrable couplings of KN hierarchy by using a pairs from special non-semisimple matrix Lie algebras and variational identities over the associated loop algebras. It is also indicated that the study of nonlinear integrable couplings using the Kronecker product is an efficient and straightforward method.

Published: November 2013

Abstract
In the present paper, a very new technique, Coupled Fractional Reduced Differential Transform, has been implemented to obtain the numerical approximate solution of coupled time fractional kdV equations. The fractional derivatives are described in the Caputo sense. By using the present method we can solve many linear and nonlinear coupled fractional differential equations. The obtained results are compared with the exact solutions. Numerical solutions are presented graphically to show the reliability and efficiency of the method.
Temporal evolution of a Polynesian hotspot: New evidence from Raivavae (Austral islands, South Pacific ocean)

Published: November 2013

Abstract
A new geological mapping of Raivavae island, Austral-Cook linear chain, French Polynesia, combined with 10 unspiked K/Ar ages measured on its lavas, shows that it was built during two successive volcanic phases : 10.6-7.4 Ma (dykes crosscutting Rairua submarine breccias and younger subaerial Rairua flows) and 6.4-5.4 Ma (Anatonu shield volcano and associated trachytic and phonolitic domes and plugs). Geochemical data from the present study and a previous one [Lassiter et al., 2003] demonstrate that the Rairua alkali basalts, picrobasalts and basanites are more enriched in incompatible elements (especially Th and Nb) than the predominantly tholeiitic Anatonu basalts. The isotopic signature of Rairua lavas displays a strong HIMU flavour, while that of Anatonu lavas is more subdued and intermediate between DMM, HIMU and EM end-members. Rairua mafic lavas show obvious petrologic and geochemical similarities with those of the neighbouring island of Tubuai. Both could result from the partial melting of a predominantly HIMU secondary plume, which formed sucessively Mangaia (19.4-18.4 Ma), the old lavas of Rurutu (12.7-12.1 Ma), Tubuai (10.0-8.8 Ma) and Rairua volcano. The geochemical signature of the younger Anatonu lavas is ascribed to the partial melting, within the same plume, of a distinct filament of more subdued composition. Alternatively, the proportion of pyroxenites with a HIMU character was lower as partial melting degrees increased, generating the Anatonu tholeiites.

Authors: Onsten Tor Gunnar Hugo , Callegari-Jacques Sidia Maria , Goldani Luciano Zubaran 
Published: November 2013

Objective:To analyze the frequency of and odds for and against HIV infection based on ABO blood type in a large sample of blood donors.Background:Coevolution between pathogens and hosts may explain the ABO system of polymorphisms. HIV-infected cells add ABO(H) blood group antigens to the viral envelope. Naturally occurring antibodies against ABO(H) antigens that are present in normal human sera are able to neutralize ABO-expressing HIVin vitro. Blood donors are ideal for studying blood groups and HIV infectionin vivobecause all donors are routinely typed and tested.Methods:All blood donors who donated blood between 1994 and 2010 were tested for HIV (ELISA antibody tests and Western blot test or immunofluorescence testing) and were ABO typed (direct and reverse grouping tests). HIV infection based on the ABO blood group was analyzed using the chi-square test and game theory.Results:The total number of examined blood donors during this period was 271,410, of whom 389 were infected with HIV. B-group donors were more infected than non-B donors (p= 0.006).Conclusions:A more restricted antigen recognition capacity of anti-Galα1-3Gal in blood groups AB and B and a weaker antigen-binding capacity of anti-A antibodies may contribute to a higher frequency of HIV infection in blood group B.

Authors: Bilková Andrea , Dubničková Martina , Sepová Hana Kiňová 
Published: November 2013

Abstract
In the process of selecting a new probiotic candidate, several bacteria were isolated from the stomach mucosa of a lamb. Among them, three lactobacilli strains were identified and partially characterised. The strain, Lactobacillus mucosae D, showed several characteristics appropriate to the probiotics. In this study, we have focused on the further characterisation of L. mucosae D and testing of its ability to modulate metabolic and immunomodulatory activities of human mononuclear cells in vitro. L. mucosae D is resistant to antibiotics, like penicillin G, oxacillin, vancomycin and chemotherapeutics ofloxacin and ciprofloxacin. In in vitro conditions, L. mucosae D caused a significant increase in phagocytic activity and index (relative activities 1.05 and 1.44, respectively) of human monocytes. It decreased bactericidal activities of monocytes against Escherichia coli (relative activity 0.73) and Staphylococcus aureus (relative activity 0.36), whereas, candidacidal activity was enhanced (relative activity 1.15). Metabolic activities, lysozyme and peroxidase activity, of mononuclear cells were not changed or increased, respectively. L. mucosae D displayed the ability to enhance production of pro-inflammatory cytokine, IL-1β, in monocytes in vitro (relative activity 2.60). Therefore, we state that lamb isolate, L. mucosae D, has the required attributes for being a potential probiotic candidate.

Abstract
Health aspects of the use of radiating devices, like mobile phones, are still a public concern. Stand-alone electrocardiographic systems and those built-in, more sophisticated, medical devices have become a standard tool used in everyday medical practice. GSM mobile phones might be a potential source of electromagnetic interference (EMI) which may affect reliability of medical appliances. Risk of such event is particularly high in places remote from GSM base stations in which the signal received by GSM mobile phone is weak. In such locations an increase in power of transmitted radio signal is necessary to enhance quality of the communication. In consequence, the risk of interference of electronic devices increases because of the high level of EMI.
In the present paper the spatial, temporal, and spectral characteristics of the interference have been examined. The influence of GSM mobile phone on multilead ECG recordings was studied. It was observed that the electrocardiographic system was vulnerable to the interference generated by the GSM mobile phone working with maximum transmit power and in DTX mode when the device was placed in a distance shorter than 7.5 cm from the ECG electrode located on the surface of the chest. Negligible EMI was encountered at any longer distance.
A Measurement and Power Line Communication System Design for Renewable Smart Grids
Authors: Kabalci E. , Kabalci Y. 
Published: November 2013

Abstract
The data communication over the electric power lines can be managed easily and economically since the grid connections are already spread around all over the world. This paper investigates the applicability of Power Line Communication (PLC) in an energy generation system that is based on photovoltaic (PV) panels with the modeling study in Matlab/Simulink. The Simulink model covers the designed PV panels, boost converter with Perturb and Observe (P&O) control algorithm, full bridge inverter, and the binary phase shift keying (BPSK) modem that is utilized to transfer the measured data over the power lines. This study proposes a novel method to use the electrical power lines not only for carrying the line voltage but also to transmit the measurements of the renewable energy generation plants. Hence, it is aimed at minimizing the additional monitoring costs such as SCADA, Ethernet-based or GSM based systems by using the proposed technique. Although this study is performed with solar power plants, the proposed model can be applied to other renewable generation systems. Consequently, the usage of the proposed technique instead of SCADA or Ethernet-based systems eliminates additional monitoring costs.
Proposition of a Solution for the Setting of the Abrasive Waterjet Cutting Technology
Authors: Valíček J. , Harničárová M. , Kušnerová M. , Grznárik R. , Zavadil J. 
Published: November 2013

Abstract
The submitted paper aims to clarify the abrasive waterjet technology, particularly from the point of view of produced surface topography. It provides a new insight into the deformation process caused by the effect of abrasive waterjet and into the possibilities of using the surface topography for solving the issues of optimization of the process. The subject of study is a system of cutting tool, material and final surface topography and optimization of their parameters. The cutting or disintegrating tool of abrasive waterjet technology is flexible. The trajectory of its cut traces is strictly determined here by disintegration resistance at critical moments of tool-material interaction. The physico-mechanical character of the interaction within the cut will manifest itself in the final surface condition. This process can be re-analysed by measuring the selected elements of topography and roughness on the final surface, namely depending on the depth of the cut, technological parameters of the tool and mechanical parameters of the material. The mentioned principle is the basis of the presented solution. It lies in the analytical processing and description of correlation interrelations between set technological and measured topographical quantities in relation to the depth of cut and the type of material.
Oedipal Complexes Freud and Artemidorus
Authors: Sick David H. 
Published: November 2013

AbstractSigmund Freud and the second-century CE dream interpreter Artemidorus of Daldis displayed a certain degree of respect for their patients or clients. This shared attitude was supported by a similar commitment to empiricism. Their similar methods in dealing with patients draw attention to their basic differences in understanding dreams in general and in interpreting incestuous dreams specifically. Freud and Artemidorus stand at variance in their interpretation of such dreams because they had different notions of the individual. For Freud, humans were defined by their biological history as animals. For Artemidorus, humans were defined by their roles in society. As a result, Freud believed the Oedipal complex to be nearly universal but represented cryptically in dreams, but Artemidorus found numerous direct examples of incestuous dreams that were to be interpreted according to the context of the dreamer's social position.

La primauté du droit, l’égalité devant la loi et autres « principes non écrits de notre constitution »
Authors: Lussier Sylvain 
Published: November 2013

Le système juridique canadien repose sur le principe fondamental de la primauté du droit. La notion de primauté du droit est conçue comme un principe constitutionnel exerçant une contrainte effective sur l’action gouvernementale indépendamment de l’existence d’une disposition législative ou constitutionnelle formelle explicite. Son importance figure au premier plan de plusieurs décisions canadiennes, dont le célèbre arrêt Roncarelli c Duplessis, où la Cour suprême du Canada a reconnu qu’un membre du gouvernement pouvait être tenu personnellement responsable de certains actes accomplis dans l’exercice de ses fonctions. C’est donc dans ce contexte que la thématique « égalité de tous sous la loi » trouve toute son importance. Elle exige que toute communauté politique adhérant à l’idéal d’un État de droit s’interroge sur les rôles légitimes respectifs du législateur, du pouvoir exécutif et des instances judiciaires.

Published: July 2024

ImportanceMost dual-eligible Medicare-Medicaid beneficiaries are enrolled in bifurcated insurance programs that pay for different components of care. Therefore, policymakers are prioritizing expansion of integrated care plans (ICPs) that manage both Medicare and Medicaid benefits and spending.ObjectiveTo review evidence of the association between ICPs and health care spending, quality, utilization, and patient outcomes among dual-eligible beneficiaries.Evidence ReviewA search was conducted of PubMed/MEDLINE (January 1, 2010, through November 1, 2023) and Google Scholar (January 1, 2010, through October 1, 2023) and augmented with reports from US federal and state government websites. Three categories of ICPs were evaluated: Programs of All-Inclusive Care for the Elderly (PACE), Medicare-Medicaid Plans (MMPs), and Fully Integrated Dual Eligible Special Needs Plans (FIDE-SNPs) and related models aligning Medicare and Medicaid coverage. The review included studies that evaluated beneficiaries dually eligible for and enrolled in full Medicaid; compared an ICP to a nonintegrated arrangement; and evaluated utilization, spending, care coordination, patient experience, or health for 100 or more beneficiaries.FindingsIn all, 26 ICP evaluations met the inclusion criteria and were included in the analysis: 5 of PACE, 13 of MMPs, and 8 of FIDE-SNPs and other aligned models. Evidence generally showed associated reductions in long-term nursing home stays in PACE (3 of 4 studies) and FIDE-SNPs and related aligned models (3 of 5 studies) but was mixed in evaluations of MMPs. Four of 9 studies of MMPs and 2 of 3 studies of FIDE-SNPs found higher outpatient use, although other studies showed no difference. Evidence on Medicaid spending was limited, whereas 8 of 10 studies of MMPs showed an association between these plans and higher Medicare spending. Evidence was mixed or inconclusive regarding care coordination and hospitalizations, and it was insufficient to evaluate patient satisfaction, health, and outcomes in beneficiary subgroups (eg, those with serious mental illness). Furthermore, studies had limited ability to control for bias from unmeasured differences between enrollees of ICPs compared with nonintegrated models.Conclusions and RelevanceThis systematic review found variability and gaps in evidence regarding ICPs and spending, quality, utilization, and outcomes. Studies found some ICPs were associated with reductions in long-term nursing home admissions, and several identified increases in outpatient care. However, MMPs were primarily associated with higher Medicare spending. Evidence for other outcomes was limited or inconclusive. Research addressing these evidence gaps is needed to guide ongoing efforts to integrate coverage and care for dual-eligible beneficiaries.
