Modified Korteweg-de Vries Hierachies in Multiple-Times Variables and the Solutions of Modified Boussinesq Equations

We study solitary-wave and kink-wave solutions of a modified Boussinesq equation through a multiple-time reductive perturbation method. We use appropriated modified Korteweg-de Vries hierarchies to eliminate secular producing terms in each order of the perturbative scheme. We show that the multiple-time variables needed to obtain a regular perturbative series are completely determined by the associated linear theory in the case of a solitary-wave solution, but requires the knowledge of each order of the perturbative series in the case of a kink-wave solution. These appropriate multiple-time variables allow us to show that the solitary-wave as well as the kink-wave solutions of the modified Botussinesq equation are actually respectively a solitary-wave and a kink-wave satisfying all the equations of suitable modified Korteweg-de Vries hierarchies.Comment: RevTex file, submitted to Proc.

A flexible one-pot route to metal/metal oxide nanocomposites

We report a one-pot route to Au/CeO2 nanocomposites. A readily-available biopolymer, sodium alginate, is exploited for controlled formation and stabilisation of gold nanoparticles followed by in situ growth of a sponge-like network of CeO2 nanoparticles. The flexible nature of this method as a general route to mixed metal/metal oxide nanocomposites is also demonstrated

Sandpile model on an optimized scale-free network on Euclidean space

Deterministic sandpile models are studied on a cost optimized Barab\'asi-Albert (BA) scale-free network whose nodes are the sites of a square lattice. For the optimized BA network, the sandpile model has the same critical behaviour as the BTW sandpile, whereas for the un-optimized BA network the critical behaviour is mean-field like.Comment: Five pages, four figure

Analisis Biaya Jaminan Kesehatan Masyarakat Dan Asuransi Kesehatan Pada Pasien Stroke Non-hemoragik Di Rumah Sakit Umum Daerah Kabupaten Sleman

Background: Non-hemorrhagic stroke causes many deaths.Its treatment requires long-term care, resulting in very highcost. Controlinging costs and quality are very important in maintainingsustainability, however, in reality there are cost sharingby patients and hospitals outside the insurance coverage.Aim: This study aims to identify the difference in cost thatmust be shared to the patient and the hospital for inpatientnon-hemorrhagic stroke of the Jamkesmas and Askes patientsin Sleman Hospital.Method: This study used a cross ssectional design. Datawere retrieved retrospectively with a primary diagnosis ofnon-hemorrhagic stroke hospitalizations for patients admittedto the hospital during the period of January 2011 to May 2012.Data were analyzed using univariate, bivariate correlation,and multivariate.Result: The average cost of inpatient care non-hemorrhagicstroke Jamkesmas patients was Rp3.541.021,00 +Rp2.609.488,00 and for Askes patients Rp4.678.509,00 +3.257.816,00. The average cost sharing in Askes patients isRp.1.851.536,00 + 1.968.757,00 and Jamkesmas isRp405.976,00 +Rp2.303.903,00. Percentage the greatest costcomponent in Askes patients is drugs (47%) and accomodation(44%), while in Jamkesmas is drug (52%) and accommodation(36%). Components of the cost sharing in Askes patients wasdrug (87%). The difference in the cost of hospital rates wasgreater than INA-CBGs respectively Rp3.541.021,00 +Rp2.609.488,00 and Rp3.135.045,00 + Rp727.710,00.Conclusion: The proportion of costs covered by the insuranceand shared by patient/hospital is 87:13 for Jamkesmaspatient, 55:45 for Askes patients (January 2011-May 2011),and 59:41 for the Askes patients (June 2011-May 2012). Theproportion of cost sharing of inpatient care non-hemorrhagicstroke by Askes patients outside the program is greater thanthe proportion of costs sharing by the hospital on Jamkesmasprogram

Self-Structuring of Granular Media under Internal Avalanches

We study the phenomenon of internal avalanching within the context of recently proposed ``Tetris'' lattice models for granular media. We define a recycling dynamics under which the system reaches a steady state which is self-structured, i.e. it shows a complex interplay between textured internal structures and critical avalanche behavior. Furthermore we develop a general mean-field theory for this class of systems and discuss possible scenarios for the breakdown of universality.Comment: 4 pages RevTex, 3 eps figures, revised version to appear in Phys.
