Analysis and Design of Bulk Acoustic Wave Filters Based on Acoustically Coupled Resonators

El rapid creixement dels sistemes de telecomunicacions sense fils ha portat a una creixent demanda de dispositius mobils amb requisits cada vegada mes estrictes per als filtres de microones incloent un millor rendiment, miniaturitzacio i la reduccio de costos. Una nova tecnologia de filtres de RF s’ha consolidat en l'ultima decada: la tecnologia BAW. Els filtres BAW son perfectament adequats com a filtres miniaturitzats i d'alt rendiment per a aplicacions d'alta frequencia. En comparacio amb la tecnologia SAW, els filtres BAW proporcionen menors perdues d'insercio, una millor selectivitat, compatibilitat CMOS, millor maneig de potencia i una major frequencia de treball. Un CRF BAW es un dels mes recents filtres BAW que permet oferir una amplia gamma de noves i interessants propietats en comparacio dels seus predecessors. Basat en el concepte de ressonadors acoblats acusticament, es poden oferir respostes Chebyshev classiques i avancades, millor ample de banda, mes miniaturitzacio i conversio de mode. La complexitat d'un CRF es considerable en termes de disseny i fabricacio, a causa de la quantitat de lamines que el conformen. El disseny de filtres BAW es basa en dimensionar les capes del dispositiu. El disseny es complex i els procediments d'optimitzacio poden no ser eficients a causa de la quantitat de variables que intervenen en el proces. En aquest treball es presenta una metodologia d'analisi i sintesi. Les tecniques poden fer front a les estructures de diverses capes d'una manera directa. Es presenta un conjunt de models circuitals completament electrics que simplifiquen i recullen el comportament dels CRF, dispositius que funcionen tant en els dominis electric i mecanic. S'han establert un conjunt d'eines per analitzar el ressonador per mitja de teoria de xarxes i es la base per a l'analisi d'estructures compostes de diversos ressonadors i multiples capes de lamines primes. Es desenvolupa un model per al CRF utilitzant transformacions de xarxa i aproximacions respecte a les frequencies de funcionament dels dispositius BAW. Es presenta un analisi profund del BAW CRF amb els models proposats com una eina que permet guiar el procediment analitic. L'analisi dels filtres facilita una millor comprensio del seu funcionament i una manera d'establir els limits de les respostes que poden oferir. Es presenten metodologies de disseny de filtres amb la finalitat d'obtenir les geometries de l'estructura i la topologia dels filtres BAW per complir amb les respostes prescrites. El disseny del filtre es dona a partir d'una comprensio clara dels seus mecanismes de filtratge de manera que facilita l'explotacio de les seves caracteristiques inherents. Les respostes avancades amb zeros de transmissio o els filtres de banda de rebuig procedents dels nous dispositius presentats es sintetitzen per mitja de les metodologies proposades.
Relative impact of the 2012 SSC guideline recommendations under the scope of numbers needed to treat (NNTs).

The surviving sepsis campaign (SSC) guidelines aimed to reduce mortality in severe sepsis and septic shock. The present study was performed to find out which and how many recommendations of the 2012 SSC update were based on significant effects from clinical studies in adult patients with severe sepsis and septic shock, leading to numbers needed to treat (NNTs). Every reference of the SSC 2012 guideline regarding clinical trials in adult patients was screened for absolute risk reduction regarding mortality to calculate NNTs. 17 relevant clinical trials out of 338 were identified. The NNTs ranged between 3.55 to 23.24. Significant reductions of mortality were detected, and items recommended in the SSC guidelines regarding early goal directed therapy (EGDT)/standard operating procedures (SOP)/sepsis bundles, early therapy with antibiotics, combined antibiotic therapy, and use of norepinephrine. Therapy with Review Article norepinephrine and the 6h bundles revealed the lowest NNTs. Significant reductions in mortality with restricted or no recommendations regarded therapy with hydrocortisone, therapy with high-dose antithrombin III, and enteral feeding with eicosapentaenoic acid, gamma-linolenic acid and antioxidants. In conclusion, only a few recommendations of the 2012 SSC guidelines are based on significant beneficial effects coming from clinical trials in patients with severe sepsis and septic shock. When transferring study results and NNTs, physicians should take into account the own setting and own subgroup of patients. If feasible, costs of additional treatment success may be quantified underlying NNTs.
Réparation de Web services composites

RESUME. A partir d’une modelisation semantique des Web services, nous voulons donner une idee d’une reparation semantique de Web services complexes defectueux afin de ne pas recommencer le processus de composition de Web services. Cette modelisation est effectuee avec un fragment d’OWL-S. Nous utilisons pour cela nos precedents travaux qui permettaient d’ordonner une bibliotheque de Web services complexes modelises en OWL-S. Nous montrons qu’une reparation bornee, qui ne change pas la structure interne du Web Service est un probleme dont la borne superieure est NEXPTIME. Nous donnons une heuristique pour reparer, car il ne faut pas que le processus de reparation soit plus couteux que celui de composition.

Die Raumordnung des Tourismus

Zusammenfassung Der Beitrag widmet sich einem von der soziologischen Theoriebildung bisher kaum beachteten Kommunikationszusammenhang: dem modernen Tourismus. Angesichts seiner Globalisierungsdynamik und vielfältiger Raumbezüge überrascht, dass auch die raumtheoretische Debatte der letzten Jahre den Tourismus weitgehend ausgespart hat. Dies nimmt der Beitrag zum Anlass, mit systemtheoretischen Mitteln nach der Funktionalität des Kommunikations- und Wahrnehmungsmediums Raum im touristischen Kontext zu fragen. Ein zentrales Ergebnis der Untersuchung lautet: Für die Entstehung, Ausdifferenzierung und Reproduktion des modernen Tourismus sind räumliche Unterscheidungen und Formbildungen konstitutiv. Warum dies so ist und in welcher Weise Raum strukturbildend wirkt, lässt sich im Rahmen einer gesellschaftstheoretischen Bestimmung des Tourismus zeigen. Hierbei wird sowohl die zentrale Rolle von Organisationen als auch die besondere Bedeutung des Raums als Medium der touristischen Erwartungsbildung deutlich. Genauer untersucht wird das Beispiel städtetouristischer Semantiken und ihrer durch Territorialisierung erzeugten Ordnungen. Die Ausführungen verstehen sich als ein Beitrag zur Theorie des Tourismus. Zugleich demonstrieren sie exemplarisch das analytische Potential eines medientheoretischen Raumkonzepts.
THE VEGETATIVE STATE: MEDICAL FACTS, ETHICAL AND LEGAL DILEMMAS

THE VEGETATIVE STATE: MEDICAL FACTS, ETHICAL AND LEGAL DILEMMAS By Bryan Jennett 2002. Cambridge: Cambridge University Press Price £29.92. ISBN 0521441587 It has been recognised for many years that, following severe brain injury, the awareness and cognitive responsiveness aspects of consciousness may be severely or totally impaired. Jennett and Plum described this as ‘the persistent vegetative state’ in 1972. Since the first paper, the vegetative state has increasingly been recognised because better techniques of resuscitation and supportive care of acute brain injuries have led to a higher proportion of patients surviving with profound cognitive impairment. Furthermore, better nursing care of dependent patients has meant that some patients may survive for prolonged periods with severe dementia. The implications of the vegetative state to society are potentially immense in both financial …
New generation power converter

Abstract This paper describes an initial investigation into the development of a new generation of power converter, used to power telecommunications equipment. The traditional topology for such power converters is a single-phase two-stage design, resulting in an overall reduction in efficiency. A power converter solution is sought that meets with all the requirements of the telecommunications industry, and which can be realised by a single-stage design. A new converter, which is a three-phase single-stage buck-derived topology, is proposed. Simulation shows that if this topology is combined with a three-phase phase-locked loop controller it can potentially meet the compliance standards.

Total Hip and Total Knee Replacement

THE indications for and benefits and limitations of modern total hip replacement have been well defined by the years of experience since the first operation in 1962.1 The operation, which is by far the most successful surgery for patients with advanced osteoarthritis and rheumatoid arthritis of the hip, is now performed an estimated 120,000 times a year in North America. Total hip replacement, in contrast to other major hip surgery, including hip fusion, osteotomy, and cup arthroplasty, is an entirely biomechanical rather than biologic solution to severe arthritis of the hip. The femoral head and part of the femoral neck .
A NTRU Based Key Generation and Data Transmission Scheme for Sensor Networks

Wireless sensor network security requires the cryptography software extremely low complex and energy ecient due to the limited memory and CPU capacity in a sensor. The NTRU (Nth degree truncated polynomial ring) encrypt algorithm has been shown to provide certain advantages when designing low power and resource constrained systems. In this paper we propose a NTRU base key generation scheme N-NTRU, and also present a data transmission scheme by using N-NTRU. Security and performance analysis shows that our scheme is resilient against several important attacks and can signicantly reduce storage and computation overhead.
The ADEMEX study: Expanding the boundaries of peritoneal dialysis adequacy beyond small solute clearances

Peritoneal small solute clearances have been extensively examined for their effect on the outcome of patients maintained on peritoneal dialysis (PD). Those studies, however, have had conflicting results. ADEMEX, or the ADEquacy of PD in MEXico, is the largest interventional study ever conducted in peritoneal dialysis examining the effects of increased peritoneal small solute clearances on mortality rates among patients on continuous ambulatory peritoneal dialysis (CAPD). Over the entire 2-year study period, the interventions succeeded in achieving a sustained separation between the intervention and control groups with regard to the mean peritoneal weekly creatinine clearance (46.1 vs. 56.9 L/wk/1.73m 2 ) and Kt/V (1.62 vs. 2.13). The results showed a neutral effect of increased peritoneal clearances on mortality, with death rates being similar in both cohorts. As in the CANUSA study, a favorable effect of residual renal function on outcome was again demonstrated in the ADEMEX study. The results highlight the need to broaden the scope of what constitutes adequate dialysis clinical care and therapeutic success beyond small molecule clearances. A comprehensive approach to improve ultrafiltration management, preserve residual renal function, optimize nutritional status, and reduce cardiovascular disease risk factors, in both the pre-dialysis and ESRD phases of chronic kidney disease, will be important in significantly and positively influencing the clinical outcomes in PD patients.
Hipertensión postparto: una revisión de la literatura y los protocolos de manejo

Antecedentes. La hipertension postparto corresponde a la presencia de cifras tensionales sistolicas superiores a 140 mmHg o diastolicas mayores a 90 mmHg, medidas en 2 ocasiones con una diferencia de 4 horas; las cuales aparecen o se sostienen en el puerperio, hasta las 12 semanas posteriores al parto (1,2). Actualmente, a excepcion de la crisis hipertensiva, el manejo de la hipertension en el posparto no esta estandarizado. Objetivo. Realizar una revision bibliografica acerca del manejo de la hipertension postparto, exceptuando la crisis hipertensiva. Materiales y metodos. Se realizo una busqueda de la literatura publicada en las bases de datos: Pubmed, Tripdatabase, Science Direct, Embase biomedical, Scielo y Ebsco, con los terminos: postpartum period, pregnancy induced hypertension, pregnancy induced hypertension and diagnosis, pregnancy induced hypertension and treatment, postpartum hypertension and management; en ingles y con sus equivalentes en espanol, sin limitacion cronologica. Resultados. Se obtuvieron alrededor de 55 articulos con informacion oportuna para cumplir con los objetivos de la presente revision; entre ellos, una revision sistematica, cuatro ensayos clinicos y dos guias de manejo. Conclusion. A pesar de que existen muchos farmacos considerados compatibles con la lactancia, existe poca evidencia sobre su seguridad para el lactante. No se recomienda el manejo farmacologico de la hipertension postparto leve a moderada. El manejo con farmacos antihipertensivos es mandatorio en hipertension severa.
Parameter sensitivity and robust estimation in an ARX model with glottal excitation

The authors demonstrate theoretically that an ARX model with glottal excitation can take into account segmentation error, but this introduces a perturbation of model parameters. A practical investigation of parameter sensitivity due to the error is reported. The parameter sensitivity can be viewed in terms of the robustness of the estimation process. The authors present a robust estimation procedure to decrease the sensitivity without an increase in computation. <<ETX>>
Word count: 4, 246 The Contribution of Hand Drying in Prevent of Transmission of Microorganisms: Comparison of the Efficacy of Three Hand Drying Methods in the Removal and Distribution of Microorganisms

Background Hand hygiene is a key tool in infection control. While methods of hand washing have been widely researched, there have been fewer studies investigating the effectiveness of available ways to dry hands in public areas. Aims This study compared the efficacy of using paper towels (PT), warm air dryers (WAD) and jet air dryers (JAD) after hand washing in terms of microbiological effectiveness and potential for dispersal of pathogens. Methods Microbial flora on palms and fingertips of 30 subjects were sampled on nutrient agar plates before washing hands and after drying with PTs, WADs and JADs. Total colony forming units (cfus) were recorded. Walls in the vicinity of a PT dispenser, WAD and JAD in female and male washrooms were sampled for the presence of viable microorganisms. Results Mean cfu significantly reduced after drying with PTs (palms t= 2.67, p <0.05; fingertips t=4.44, p<0.01) significantly increased after using WADs (palms t=3.11, p<0.01; fingertips t=2.06, p<0.05) , but there was no difference with JAD (palms t= 1.85, p>0.05; fingertips t=0.97, p>0.05). Some dispersal of organisms was detected on the washroom walls, with the least distribution around PT dispensers and unusual opportunistic pathogens isolated from the JAD units. Discussion PTs are more effective at drying hands than WADs and JADs, they are more likely to be used appropriately and lead to minimal dispersal of microorganisms from wet hands.
Different approaches in parallelization of the artificial bee colony algorithm

Parallel processing is gaining popularity due to the low cost of multi-core processors. In this paper we propose three different approaches in parallelization of standard artificial bee colony (ABC) algorithm. ABC algorithm was successfully used on many optimization problems, unconstrained and constrained. Our three approaches are independent parallel runs and two variations of multiple swarms parallelization. By using independent parallel runs method we succeeded in achieving faster execution of algorithm since multicore processors can be better utilized. By using multiple swarms technics with some modifications we also obtained better results than the original ABC algorithm. Different types of communications among swarms are proposed and examined. These methods of communication between swarms improved results and allowed adjustments of different ratios between exploration and exploitation. Set of eleven standard benchmark functions was used to test execution speed and quality of results improvements. Keywords—Artificial bee colony, Metaheuristic optimization, Parallelization, Swarm intelligence, Nature inspired metaheuristic algorithms.
Test de Raven: Actualización de Baremos en Adolescentes Argentinos y Análisis del Efecto Flynn

espanolSe presentan los resultados obtenidos en la construccion de normas actualizadas del Test de Matrices Progresivas de Raven, Escala General, para la ciudad de La Plata, Argentina; y su comparacion con las obtenidas en los anos 1964 y 2000. Con ese proposito se selecciono una muestra de 1049 sujetos de ambos sexos, de 13 a 18 anos de edad, alumnos de educacion secundaria. El instrumento fue administrado colectivamente y sin limite de tiempo. Los resultados se analizaron en tres grupos de edad y se compararon con los baremos anteriores. Se observo que a mayor edad de los sujetos, su rendimiento es mejor. La variabilidad de los puntajes es similar en los grupos de edad. En relacion con la tipificacion del ano 2000, en la que se constato el efecto Flynn respecto de las normas de 1964, aparece un amesetamiento y leve descenso de los puntajes directos necesarios para alcanzar el rendimiento promedio. Asimismo se observaron diferencias en el orden de dificultad entre las series de la prueba. El conjunto de estos resultados confirman la necesidad de actualizacion de los baremos y de las caracteristicas del material de prueba, a los fines de una evaluacion precisa EnglishThe current paper presents the results of the construction of valid and updated norms for Raven’s Standard Progressive Matrices, in the city of La Plata, Argentina, and compares them with norms obtained in the years 1964 and 2000 in order to observe score trends. For this purpose a sample of 1049 subjects of both sexes, 13-18 years old, high school students were selected. The test was administered collectively, without time limit. Data was split into three age groups and results were compared withnorms from 1964 and 2000. It was also noticed that as age increases, subjects performance tend to improve. The scores variability is similar in all age groups. A slight decrease of the direct scores needed to reach an average performance was observed, when compared to those from 2000, which were the norms where the Flynn effect was first noted after 1964 and show a plateau effect in direct scores. It was also noticed that as age increases, subjects performance tend to improve. The scores variability is similar in all age groups. Also differences in the order of difficulty between test series were observed. All these results confirm the need for updating of the scales and the characteristics of the test material for the purposes of an accurate assessment

The present cross sectional study was conducted undergraduate medical students of 18-25 years of age. Student stress questionnaire was used to assess the stress levels. In the present study, first and final year students were found to be highly stressful. Our study highlights the need of implementation of effective counseling and relaxation techniques to decrease their stress level.
Mejoras al Algoritmo de Marching Cubes

Uno de los algoritmos de rendering de volumenes mas difundido y utilizado es el denominado marching cubes, propuesto por Lorensen y Cline en 1987 [3]. En el mismo se busca extraer una superficie umbral a partir de una matriz volumetrica de datos escalares. Una celda en el espacio esta delimitada por los ocho valores de sus vertices. Cada celda se clasifica en distintas configuraciones segun los valores de sus vertices respecto al valor umbral. Una celda pertenece a la superficie umbral si por lo menos uno de sus vertices esta por debajo del valor umbral y por lo menos otro esta por encima. En este caso, cada uno de los ocho vertices de una celda puede asumir un valor por debajo o por encima del umbral. El total de todas las configuraciones posibles es 28=256, pero por consideraciones de simetria se reducen a solo 15 (ver Fig. 1).
QuickSet: A Multimodal Interface for Distributed Interactive Simulation

We demonstrate QuickSet, a wireless, handheld, collaborative, system that can be used to control distributed interactive simulations based on the ModSAF simulator [3] and a 3-D terrain visualization system called CommandVu. Together with the CommandTalk spoken interaction component from SRI International [4] these form the LeatherNet system [1]. With QuickSet, users can formulate a military scenario by creating, positioning, and editing units, supplying them with behavior, specifying fortifications, objectives and other points, etc. In contrast to the original ModSAF GUI, users of QuickSet can employ multiple input modalities, including speech, gesture, and direct manipulation, to suit the task and situation at hand. QuickSet operates on a 3-lb. handheld 100MHz 486 PC (Fujitsu Stylistic 1000), as well as desktop PC's, employing wireless LAN communications, color screen, microphone, pen stylus, onboard speech recognition, gesture recognition, natural language processing, and multimodal integration. These components communicate with one and the other components of LeatherNet via the Open Agent Architecture [2]. Figure 1 shows collaborative use of the system for creating units, areas, lines, and minefields. QuickSet can run standalone on the handheld, with a "stub" component emulating ModSAF, and can under user control, upload its scenario to ModSAF to be simulated. Other users can do likewise, with the net effect being an accumulation of entitites and behaviors. For example, this capability can be used for one party playing "blue" and the another "red. " When connected online, the handhelds track the ongoing simulation, and therefore are collaborative, in that each can see and effect the course of the simulation. Users can also couple their handheld systems, so that panning and zooming of one will cause identical activity on the others.
