Classical and quantum approaches to the interaction of light and matter at the nanoscale

Esta tesis aborda el estudio teorico de la interaccion de luz con nanomateriales. En primer lugar se desarrolla un modelo que explica las diferencias espectrales entre las secciones eficaces de absorcion, dispersion, y el campo cercano en nanoparticulas metalicas debida a la excitacion de plasmones, cuando estas presentan fuertes contribuciones de transiciones interbanda. En este tipo de estructuras la evolucion de la dinamica de dichas excitaciones plasmonicas presenta una dinamica no lorenciana. Asi mismo, se estudia la interaccion de luz con nanoparticulas dielectricas con indice de refraccion alto. De manera contraria a las nanoparticulas metalicas que excitan modos de excitacion electricos, las nanoparticulas dielectricas presentan modos magneticos intensos y diferenciados de los modos electricos. Se ha obtenido la respuesta de estos modos frente a dos tipos de excitaciones fundamentales: una onda plana incidente, y emisores electrico y magnetico en la proximidad de la nanoparticula. Los resultados del aumento de la emision de ambos tipos de emisores en nanoparticulas esfericas y dimeros hacen que estas estructuras dielectricas puedan competir con sus homologos plasmonicos como nanoantenas opticas. Finalmente, se ha ido mas alla de la descripcion clasica de la interaccion de luz y materia, y se ha adoptado una cuantizacion de los campos electromagneticos para describir la dispersion inelastica de la luz en un proceso de espectroscopia Raman aumentado por el campo electromagnetico, en el marco de la optica cuantica. Se ha desarrollado un hamiltoniano de interaccion entre las vibraciones de una molecula y el campo electromagnetico de una particula plasmonica que ha revelado un regimen de senal Raman altamente no-lineal, asi como la posibilidad de estudiar las correlaciones de los fotones emitidos.
Scaffold‐free cell sheet injection results in bone formation

We previously reported a new cell transplantation method in which mesenchymal stem cells (MSCs) were cultured as cell sheets. The cultured MSC sheets showed high alkaline phosphatase (ALP) activities and osteocalcin (OC) contents. In the present study, we transplanted such sheets by injection to assess whether the injectable MSC sheets could form bone tissue at subcutaneous sites. At 4 weeks after the subcutaneous injection, the injected areas showed hard mass formation. Each mass consisted of newly formed bone, as evaluated by radiographic, histological and gene expression analyses as well as three‐dimensional computed tomography (3D‐CT). Histological analyses revealed extracellular bone matrix together with osteocytes and active osteoblasts. Real‐time PCR analyses showed high ALP and OC mRNA expressions. We also injected the cell sheets into dead bone to determine whether the lost osteogenic potential could be rescued, and histological analyses revealed that the injected cell sheets supplied osteogenic potential to the dead bone. The present study clearly indicates that osteogenic MSC sheets can be transplanted via injection through a needle and that bone formation results in the injected areas. Owing to its usage of a needle for fabrication of in vivo bone tissue, this injection method can be applied as a minimally invasive approach for hard tissue reconstruction.

Exponential stabilization of an unstable parabolic PDE system using boundary optimal control

In this paper, we consider an unstable linear parabolic diffusion-reaction PDE system with an actuator at the right boundary via the Dirichlet condition. We begin to derive the first order necessary conditions for the open loop finite-time horizon problem using the classical variational approach. Then, we discuss the the state-feedback problem, and obtain the feedback law by formulating the Riccati partial differential equation (PDE). Finally, with the feedback law, we could prove the stability for the state-feedback problem exponential stability with any given decay rate in the time domain without solving the Riccati PDE.
The Gene Encoding the Low-Affinity Penicillin-Binding Protein 3r in Enterococcus hirae S185R Is Borne on a Plasmid Carrying Other Antibiotic Resistance Determinants

ABSTRACT Two plasmid-derived NcoI DNA fragments of 14 and 4.5 kb, respectively, have been isolated from the multidrug-resistant strain Enterococcus hirae S185R and analyzed. The 14-kb fragment contains two inverted (L and R) IS1216 insertion modules of the ISS1 family. These modules define a Tn5466 transposon-like structure that contains one copy of the methylase-encoding ermAMconferring erythromycin resistance and one copy of the adenylyl-transferase-encoding aadE conferring streptomycin resistance. Immediately on the left side of IS1216L there occurs a copy of pbp3r encoding the low-affinity penicillin-binding protein (PBP) PBP3r, itself preceded by apsr-like gene (psr3r) that controls the synthesis of PBP3r. ermAM, aadE, and the transposase gene (tnp) of IS1216R have the same polarities, and these are opposite those of psr3r,pbp3r, and the tnp gene of IS1216L. The 4.5-kb fragment is a copy of the 4.5-kb sequence at the 5′ end of the 14-kb fragment, although it is not a restriction product of the 14-kb fragment. It contains three genes with the same polarity:psr3r, pbp3r, and tnp in an IS1216 element. Because of the very high degree of identity (99%) with the chromosomal psrfm and pbp5fmgenes of Enterococcus faecium D63R, it is proposed that both the psr3r and pbp3r genes were transferred from an E. faecium strain and inserted in a plasmid ofE. hirae. E. hirae is the first known bacterial species in which a low-affinity PBP-encoding gene has been found to be plasmid borne.
Using Cyclic Prefix Correlation for DVB-T signals detection

Spectrum sensing is an essential part of the cognitive radio systems which can be the solution for radio spectrum shortage. There are various methods of the signal detection; many of them are based on the energy detector. Another group of methods is based on known detected signal parameters as the method for DVB-T signal detection described in this paper. Because DVB-T uses OFDM with cyclic prefix, the computation of cyclic prefix correlation and the consequent correlation function level monitoring are proposed. The simulations of this method and their results are described in the paper. Test DVB-T signal with various C/N ratios is obtained by sampling of the output of the vector signal generator and complete signal processing is implemented in Matlab with Parallel Computing Toolbox support. The performance of investigated method for DVB-T signal detection is discussed in the paper.
PROCESSING PP AND PS WAVES IN MULTICOMPONENT SEA-FLOOR DATA FOR AZIMUTHAL ANISOTROPY : THEORY AND OVERVIEW

Les variations azimutales d'amplitude PP, la vitesse de move-out et le move-out dÕintervalle prsentent des variations elliptiques dans un milieu azimutalement anisotrope. Ceci peut servir  dterminer lÕazimut de la fracture et a t vrifi sur des donnes relles. Mais les effets sur les ondes P interviennent seulement sur des azimuts multiples et d'autres facteurs en compliquent l'analyse. Ceci limite dans une certaine mesure l'application de l'analyse des ondes P. L'analyse des ondes PS peut de ce fait s'avrer trs utile. Pour des ondes PS dont la propagation est proche de la verticale, la polarisation et la diffrence de temps de propagation des ondes transversales permettent une mesure directe de l'orientation et de l'intensit de la fracturation. Pour une acquisition en 2D o le profil est parallle au cble rcepteur, une mthode optimale est propose pour dterminer l'azimut de la fracture  partir de l'azimut de polarisation de l'onde transversale rapide. La mthode utilise l'analyse des rotations et suppose que les ondes transversales rapides et lentes ont des formes dÕonde similaires. Pour une gomtrie transversale en 3D o le profil est perpendiculaire au cble rcepteur, deux mthodes de dtermination sont proposes. La premire repose sur le changement de polarit et la diminution de l'amplitude dans les regroupements azimutaux de la composante gophonique transversale. La seconde mthode implique une rotation de paires orthogonales de regroupements azimutaux du rcepteur-source. L'azimut de polarisation que l'on a dtermin permet ensuite de dissocier les ondes transversales rapides et lentes dans les regroupements de champs directs pour estimer le temps de propagation.
Love at First Sight or Sustained Effect? The Role of Perceived Affective Quality on Users’ Cognitive Reactions to IT

This research examines the impact of primitive affective reactions to information technology on subsequent cognitive reactions and behavioral intention on IT use, and the potential change of such impact over time. We ground our work in theories of psychology and information systems and propose a theoretical model in which the user’s perceptions regarding the affective quality of an IT influences cognitive reactions and behavioral intention to use IT. The model was validated by surveys in two field studies of 226 and 196 college students, respectively, who were asked to evaluate a course management system, WebCT. The first study occurred during weeks 3 and 4 of the spring 2004 semester, when subjects were getting familiar with WebCT for their classes. The second study ran during weeks 11 and 12 of the same semester, when WebCT had been used quite intensively in the classes. The theoretical model is supported by both studies, indicating that the impact of perceived affective quality persists, even when subjects’ familiarity with and use of the IT increases. Our research identifies perceived affective quality as another, more-fundamental, and sustained source of user intention of IT use that has not been widely recognized yet. From a theoretical perspective, this research breaks the conventional cognition-driven paradigm of studying user reactions to technology and calls for attention to affect and emotion in examining people’s everyday, normal interactions with IT. Practically, the research provides empirical evidence for IT designers, trainers, and stakeholders to better strategize their resources and emphases.
Calibrating distance mapping of non-SVP catadioptric camera of the soccer robot

Purpose – The purpose of the present paper is to propose a full model‐based method for distance‐mapping calibration for the non‐SVP (non‐single viewpoint) catadioptric camera of the soccer robot. The method should be easy to operate, efficient, accurate, and scalable to fit larger field sizes.Design/methodology/approach – The distance‐mapping model was first constructed based on the imaging principle. The authors then calibrated the internal parameters using the mirror boundary and used the mirror center to choose the correct pose from two possible solutions. The authors then proposed a three‐point method based on a unique solution case of the non‐SVP P3P (perspective‐three‐point) problem to solve the external parameters. Lastly, they built the distance mapping by back‐projection.Findings – The simulation experimental results have shown that the authors' method is very accurate even when there is severe misalignment between the mirror and the camera and that all calibration operations, except the calibrat.
Factor Analysis of Internal and External Self-Control Practices for Alcohol Consumption

A factor analysis of specific alcohol-related self-control practices reported by 410 young adults who completed a Self-control Questionnaire, consisting of both internal and external self-control measures, is described. Seven factors were extracted from the external self-control items including Rate Control, Self-reinforcement and Punishment, Alternatives, Avoidance, Limiting Driving and Cash, Controlling Time and Food, and Awareness. Three factors emerged from the internal self-control items including Impairment, Relaxation, and Anxiousness. These specific groupings of external and internal self-control variables should be empirically tested for their utility as interventions aimed at moderating the alcohol consumption of young adults.
Advanced techniques of disruption prediction, application to JET and extrapolation to ITER

Esta tesis aborda las bases de datos masivas generadas por los dispositivos experimentales de fusion nuclear. Se utilizan tecnicas de inteligencia artificial y algoritmos de aprendizaje automatico para resolver problemas especificos en fusion nuclear con datos muy ruidosos y altamente desbalanceados. Este trabajo se centra en la prediccion de disrupciones y sus bases de datos. Las disrupciones son la inestabilidad mas peligrosa en los dispositivos tokamak, por ello es necesario predecirlas con efectividad para llevar a cabo acciones de mitigacion. Sin embargo, los datos proporcionados para desarrollar predictores no son triviales, es necesario realizar un estudio y analisis exhaustivo para posteriormente procesarlos. Esta tesis esta estructurada en cinco capitulos. El capitulo 1 explica los conceptos mas importantes sobre fusion nuclear y resume la fisica de plasma fundamental para entender el contexto de la tesis. Este capitulo aborda el problema mas importante en un tokamak, las disrupciones. En el capitulo 2 se explican las tecnicas de mineria de datos y aprendizaje automatico utilizadas. El capitulo 3 muestra la generacion de las bases de datos utilizadas en esta tesis y otros trabajos. En este mismo capitulo se explica el predictor APODIS y los trabajos realizados con este predictor: los resultados y funcionamiento del predictor durante las campanas de pared metalica (ILW) en JET (Joint European Torus), un analisis de robustez para determinar las caracteristicas mas importantes y la implementacion de un mecanismo de ventanas deslizantes para cambiar la resolucion temporal. En el capitulo 4 se desarrolla una herramienta automatica para determinar el instante de disrupcion. Finalmente el capitulo 5 contiene los estudios de prediccion de disrupciones en vistas a las nueva generacion de dispositivos de fusion: un nuevo predictor de una sola capa, predictores partiendo de cero y un analisis de la dinamica del plasma alrededor del tiempo de la disrupcion.
Quality-of-Life Weights for the US Population: Self-Reported Health Status and Priority Health Conditions, by Demographic Characteristics

Background:Many of the large ongoing national surveys of the US population contain a question that asks for the respondent's self-reported health status: “excellent,” “very good,” “good,” “fair,” or “poor. ” These surveys could be used to conduct cost-utility analyses of health care policies, treatments or other interventions if quality-of-life (QOL) weights for the self-reported health statuses were also available. Objective:The objective of this study was to produce nationally representative QOL weights for self-reported health status and for 10 “priority” health conditions, by a series of demographic variables. Research Design:The Medical Expenditure Panel Survey contains the questions from the EQ-5D health status measure. A recent study has calculated time-trade-off-derived QOL weights corresponding to the EQ-5D health states for a large sample of Americans. We use these data to construct QOL weights for the 5 self-reported health status categories and 10 priority health conditions, by a series of demographic variables. Results:Mean and median QOL weights were produced for self-reported health status, the 10 priority health conditions, and the demographic variables. We also report mean QOL weights for the self-reported health state and priority health conditions, by the demographic variables. Finally, ordinary least squares and censored least absolute deviation regression equations were used to estimate adjusted QOL weights for these variables. Conclusions:By providing nationally representative QOL weights for self-reported health status and 10 priority health conditions, by demographic variable, we have facilitated the use of large national surveys for conducting cost-utility analysis and increased their value to researchers and policy makers.
Simple Uplink SOA Pattern Effects Compensation for Reach-Extended 10G-EPONs

A simple and effective technique enabling strong pattern effects mitigation in uplink in-line semiconductor optical amplifiers (SOAs) for reach-extended, high-speed, passive optical networks, is proposed and experimentally demonstrated. The technique relies in selectively injecting into the saturated amplifier a low-power CW assist light (AL) at shorter wavelength than the data signal. The presence of the AL, which is enabled when the power level of input data triggers pattern effects in the SOA, clamps the carrier density with almost negligible gain reduction at the 1.3 μm data wavelength. By injection of an AL signal at 1.27 μm with 1 mW power in the booster SOA of a two-SOA cascade reach-extender, an increase as large as 7 dB in the access span loss dynamic range for error-free transmission at 10 Gb/s is reported with a trunk span loss of 23 dB.
Heat shock response of spirochetes

We examined the heat shock response of the pathogenic spirochetes Treponema pallidum, Borrelia burgdorferi, and Leptospira interrogans and certain saprophytic spirochetes. Cellular proteins synthesized after shifts to higher temperatures were [35S]methionine labeled and analyzed by gel electrophoresis and fluorography. Only T. pallidum failed to exhibit an obvious heat shock response. GroEL and DnaK homologs were identified in the various species, although these proteins were not thermoinducible in T. pallidum or Treponema denticola. DNA hybridization studies indicate that spirochetal groEL and dnaK genes are highly conserved.
Reactive oxygen species and ethylene play a positive role in lateral root base nodulation of a semiaquatic legume

Lateral root base nodulation on the tropical, semiaquatic legume Sesbania rostrata results from two coordinated, Nod factor-dependent processes: formation of intercellular infection pockets and induction of cell division. Infection pocket formation is associated with cell death and production of hydrogen peroxide. Pharmacological experiments showed that ethylene and reactive oxygen species mediate Nod factor responses and are required for nodule initiation, whereby induction of division and infection could not be uncoupled. Application of purified Nod factors triggered cell division, and both Nod factors and ethylene induced cavities and cell death features in the root cortex. Thus, in S. rostrata, ethylene and reactive oxygen species act downstream from the Nod factors in pathways that lead to formation of infection pockets and initiation of nodule primordia.
Automatic Control of Aircraft in Longitudinal Plane During Landing

Automatic control of aircraft during landing is discussed and a new structure of automatic landing system (ALS) is designed using the dynamic inversion concept and proportional-integral-derivative (PID) controllers in conventional and fuzzy variants. Theoretical results are validated by numerical simulations in the absence or presence of wind shears and sensor errors.
Efficient SimRank-Based Similarity Join

Graphs have been widely used to model complex data in many real-world applications. Answering vertex join queries over large graphs is meaningful and interesting, which can benefit friend recommendation in social networks and link prediction, and so on. In this article, we adopt “SimRank” [13] to evaluate the similarity between two vertices in a large graph because of its generality. Note that “Simank” is purely structure dependent, and it does not rely on the domain knowledge. Specifically, we define a SimRank-based join (SRJ) query to find all vertex pairs satisfying the threshold from two sets of vertices U and V. To reduce the search space, we propose a shortest-path-distance-based upper bound for SimRank scores to prune unpromising vertex pairs. In the verification, we propose a novel index, called h-go cover+, to efficiently compute the SimRank score of any single vertex pair. Given a graph G, we only materialize the SimRank scores of a small proportion of vertex pairs (i.e., the h-go cover + vertex pairs), based on which the SimRank score of any vertex pair can be computed easily. To find the h-go cover + vertex pairs, we propose an efficient method without building the vertex-pair graph. Hence, large graphs can be dealt with easily. Extensive experiments over both real and synthetic datasets confirm the efficiency of our solution.
Direct immunofluorescence for typing of tsutsugamushi disease rickettsia.

Fluorescent antibody prepared from sera from guinea pigs immunized with Gilliam, Karp and Kato strains of tsutsugamushi disease rickettsia showed higher staining titers against the homologous than against the heterologous strains. A possible application of the direct immunofluorescent technique for typing of newly isolated rickettsia strains is suggested.
Outcome of Medial Versus Combined Medial and Lateral Hamstring Lengthening Surgery in Cerebral Palsy

Pre- and postoperative gait analysis and static measurements from 37 children with cerebral palsy who underwent hamstring lengthening were evaluated. Significant improvements in static and kinematic measures were noted after surgery in both groups. Although the differences were not statistically significant, there was a suggestion that combined medial/lateral hamstring lengthening may provide greater improvement in popliteal angle and maximum knee extension in stance. However, there also appears to be a greater risk of knee hyperextension during gait after combined medial and lateral hamstring lengthening than after medial hamstring lengthening alone. Postoperative calf spasticity also appears to be a risk factor for postoperative knee hyperextension. Assessment of calf spasticity may be important in patients undergoing medial and lateral hamstring lengthening. Additional treatments such as bracing and/or botulinum toxin injections to the calf to control equinus and knee hyperextension may be beneficial.
Recursive Updates in Copy-on-write File Systems - Modeling and Analysis

Copy-On-Write (COW) is a powerful technique for data protection in file systems. Unfortunately, it introduces a recursively updating problem, which leads to a side effect of write amplification. Studying the behaviors of write amplification is important for designing, choosing and optimizing the next generation file systems. However, there are many difficulties for evaluation due to the complexity of file systems. To solve this problem, we proposed a typical COW file system model based on BTRFS, verified its correctness through carefully designed experiments. By analyzing this model, we found that write amplification is greatly affected by the distributions of files being accessed, which varies from 1.1x to 4.2x. We further found that write amplification is also affected by the number of files being accessed, the number of files contained in a file system, and as well as the space utilization of file system trees.
A CROSS SECTIONAL STUDY OF ADVERSE DRUG REACTIONS IN A TERTIARY CARE TEACHING HOSPITAL

The aim of this study was to carry out Adverse Drug Reactions (ADRs) monitoring in various departments of a tertiary care teaching hospital. Methods: A cross sectional study was carried out on ADRs in a tertiary care teaching hospital in Potheri from June to December 2013 after Institutional Ethics Committee approval. Result: Total 32 ADRs were reported. Among them, 46.87% were in males and 53.12% were in females. The majority of ADRs were due to antimicrobial agents (71.78%) followed by antiepileptics (18.75%). Maximum number of patients (81.25%) was reported with dermatological manifestations. Highest number of ADRs was reported from the department of medicine (37.5%). As per Naranjo’s probability scale, 50% reports were assessed as possible and 46% as probable. 75% reports were documented as moderate according to Modified Hartwig’s criteria for severity assessment. The present study was done to emphasize the importance of pharmacovigilance among practicing physicians.
