An annular-ring slot antenna with CP radiation and harmonic suppression

A microstrip-line fed annular-ring slot antenna with circularly polarized (CP) radiation is initially studied. To achieve harmonic suppression for this antenna, the technique of loading a defected ground structure into the ring slot is proposed. Measured and simulated results show that the proposed antenna can achieve broad CP bandwidth of 9.7% (2.26-2.49 GHz), while good harmonics suppression from 3 to 10 GHz are also demonstrated.
Modulation for three-phase transformerless neutral point clamped inverter in photovoltaic systems

In this paper is proposed modulation techniques for reducing leakage current in grounded photovoltaic panels for three-phase transformerless neutral point clamped inverters, which appear if there is no galvanic isolation between the photovoltaic system and the electric grid. The control is done by applying appropriate pulse width modulation techniques, that are capable of reducing the leakage currents in photovoltaic systems by applying three medium vectors or using only two medium vectors and one specific zero vector to compose the reference vector. To validate the simulation models, an experimental three-phase inverter is used to evaluate leakage currents and the dc link voltage control.
USING AHP AND DEA IN COMPARATIVE STRATEGIC ANALYSIS OF POLISH REGIONS

The aim of this article is to verify the possibility of implementing methods of AHP (Analytic Hierarchy Process) and DEA (Data Envelopment Analysis) for strategic analysis of regions using Poland as an example. The subject taken, fits in both the economic theory of regional development, as well as the concepts of New Public Management, public governance and theory of strategic management. All of these theoretical approaches are in the circle of economics and management science. The study is also characterized by the high potential for its implementation. The results can be used, among others, to evaluate the effectiveness of the potential usage in creating the production capacity and building attractiveness in relation to stakeholders. In describing the potential and attractiveness of the region, two models of AHP were constructed. They are: Regional Attractiveness Model (SEEGI Model) and Regional Potential Model (TCB Model). The first one takes into account criteria such as: Society, Economy, Environment, Government and Infrastructure. Attractiveness is evaluated in relation to the three groups of customers: Tourists, Citizens and Businesses. Appropriately selected statistical variables were introduced at the level of sub-criteria for both models. Evaluation of the validity of the criteria and sub-criteria were based on assessments of the experts involved in local development. The level of attractiveness and the level of potential of regions were calculated using weights of the significance of the model’s components and normalized values of statistical variables. The production level in the region was measured by the GDP (Gross Domestic Product). To evaluate the effectiveness of potential the DEA method was applied. The study evaluated the effectiveness of expenditures described by criteria of the SEEGI Model in relation to the effects described by: GDP value and criteria the TCB Model.
Mongolism (mongoloid deficiency) during early infancy; some newly recognized diagnostic changes in the pelvic bones.

IN MONGOLOID defectives, stigmas in the skeleton have been reported at several sites: hypoplasia of the base of the skull; hypoplasia of the nasal and other facial bones, and dysplasia and hypoplasia of metacarpals and phalanges. Undergrowth of the vertebral bodies and the tubular bones in the extremities is responsible for the dwarfism which is one of the most consistent components of this syndrome. Maturation of the skeleton varies greatly in different mongoloid infants; it may be advancecd, normal, or retarded. At birth practically all infants with mongolism show normal or advanced maturation, in our experience. Spitzer and Robinson found the frontal sinuses to be absent in 26 out of 28 individuals with mongolism in contrast to an absence in 4 to 5 per 100 of the remainder of the general population. Only 2 of the 28 individuals with mongolism showed no dental aplasia. The erupted teeth were commonly stunted, eruption of the permanent teeth was often delayed, and there was a higher incidence of the dental anomalies found than in the general population. No pathognomonic lesions in the teeth were found. The partial anodontia, deformed teeth and delayed eruption resemble the changes found in ectodermal dysplasia and in cleidocranial dysostosis. Smith and McKeown found the mean weights of newly born infants with mongolism to be 2860 gm. in contrast to 3220 gm. for normal newborns. the mean duration of gestation to he shorter for infants with mongolism than for normal newborns, 269 days and 278 days respectively. So far as we have been able to ascertain, stigmas in the pelvic bones of infants with mongolism have not been reported in either anatomical or roentgenographic studies.
An analysis of the delayed response to Hurricane Katrina through the lens of knowledge management

In contrast to many recent large-scale catastrophic events, such as the Turkish earthquake in 1999, the 9/11 attack in New York in 2001, the Bali Bombing in 2002, and the Asian Tsunami in 2004, the initial rescue effort towards Hurricane Katrina in the U.S. in 2005 had been sluggish. Even as Congress has promised to convene a formal inquiry into the response to Katrina, this article offers another perspective by analyzing the delayed response through the lens of knowledge management (KM). A KM framework situated in the context of disaster management is developed to study three distinct but overlapping KM processes, namely, knowledge creation, knowledge transfer, and knowledge reuse. Drawing from a total of more than 400 documents—including local, national, and foreign news articles, newswires, congressional reports, and television interview transcripts, as well as Internet resources such as wikipedia and blogs— 14 major delay causes in Katrina are presented. The extent to which the delay causes were a result of the lapses in KM processes within and across the government agencies are discussed.
Impact of transfection with total RNA of K562 cells upon antigen presenting, maturation, and function of human dendritic cells from peripheral blood mononuclear cells

BACKGROUND: Vaccination of dendritic cells (DCs) with tumor antigens is a potential strategy to induce tumor‐specific immunity in tumor‐bearing patients. The purpose of this study was to investigate whether human monocyte‐derived DCs were able to present P210Bcr‐Ab1 protein and induce antigen‐specific cytotoxic T lymphocyte (CTL) responses in vitro after transfected with total RNA of K562 cells (K562‐RNA).

Relaxation effects of ferucarbotran‐labeled mesenchymal stem cells at 1.5T and 3T: Discrimination of viable from lysed cells

Human mesenchymal stem cells (hMSCs) were labeled with Ferucarbotran by simple incubation and cultured for up to 14 d. Iron content was determined by spectrometry and the intracellular localization of the contrast agent uptake was studied by electron and confocal microscopy. At various time points after labeling, ranging from 1 to 14 d, samples with viable or lysed labeled hMSCs, as well as nonlabeled controls, underwent MRI. Spin‐echo (SE) and gradient‐echo (GE) sequences with multiple TRs and TEs were used at 1.5T and 3T on a clinical scanner. Spectrometry showed an initial iron oxide uptake of 7.08 pg per cell. Microscopy studies revealed lysosomal compartmentalization. Contrast agent effects of hMSCs were persistent for up to 14 d after labeling. A marked difference in the T2 effect of compartmentalized iron oxides compared to free iron oxides was found on T2‐weighted sequences, but not on T *2 ‐weighted sequences. The observed differences may be explained by the loss of compartmentalization of iron oxide particles, the uniformity of distribution, and the subsequent increase in dephasing of protons on SE images. These results show that viable cells with compartmentalized iron oxides may—in principle—be distinguished from lysed cells or released iron oxides. Magn Reson Med, 2009. © 2009 Wiley‐Liss, Inc.
Left-ventricular epi- and endocardium extraction from 3D ultrasound images using an automatically constructed 3D ASM

In this paper, we propose an automatic method for constructing an active shape model (ASM) to segment the complete cardiac left ventricle in 3D ultrasound (3DUS) images, which avoids costly manual landmarking. The automatic construction of the ASM has already been addressed in the literature; however, the direct application of these methods to 3DUS is hampered by a high level of noise and artefacts. Therefore, we propose to construct the ASM by fusing the multidetector computed tomography data, to learn the shape, with the artificially generated 3DUS, in order to learn the neighbourhood of the boundaries. Our artificial images were generated by two approaches: a faster one that does not take into account the geometry of the transducer, and a more comprehensive one, implemented in Field II toolbox. The segmentation accuracy of our ASM was evaluated on 20 patients with left-ventricular asynchrony, demonstrating plausibility of the approach.
Paradoxical side effects of green advertising: how purchasing green products may instigate licensing effects for consumers with a weak environmental identity

Abstract Research into green advertising has mainly investigated how green appeals can enhance product attitudes, sales, and brand image. But what happens after people have purchased a ‘green’ product advertised in a green ad? In two experiments, we show that purchasing a green product may have paradoxical post-purchase effects, such that it may lower intentions to engage in subsequent environmentally friendly behaviour (a so-called licensing effect). Importantly, our results show that these post-purchase effects are moderated by environmental identity: only people with a weak environmental identity show these paradoxical post-purchase licensing effects, people with a strong environmental identity are more likely to continue behaving in an environmentally friendly way.
Spatiotemporal calibration and resolution refinement of output from deterministic models

Spatiotemporal calibration of output from deterministic models is an increasingly popular tool to more accurately and efficiently estimate the true distribution of spatial and temporal processes. Current calibration techniques have focused on a single source of data on observed measurements of the process of interest that are both temporally and spatially dense. Additionally, these methods often calibrate deterministic models available in grid‐cell format with pixel sizes small enough that the centroid of the pixel closely approximates the measurement for other points within the pixel. We develop a modeling strategy that allows us to simultaneously incorporate information from two sources of data on observed measurements of the process (that differ in their spatial and temporal resolutions) to calibrate estimates from a deterministic model available on a regular grid. This method not only improves estimates of the pollutant at the grid centroids but also refines the spatial resolution of the grid data. The modeling strategy is illustrated by calibrating and spatially refining daily estimates of ambient nitrogen dioxide concentration over Connecticut for 1994 from the Community Multiscale Air Quality model (temporally dense grid‐cell estimates on a large pixel size) using observations from an epidemiologic study (spatially dense and temporally sparse) and Environmental Protection Agency monitoring stations (temporally dense and spatially sparse).

MRI reveals structural abnormalities in patients with idiopathic generalized epilepsy

Objective: To evaluate MRI findings in a large group of patients with idiopathic generalized epilepsies. Methods: Idiopathic generalized epilepsies were diagnosed according to clinical and EEG criteria following International League Against Epilepsy recommendations. MRI was performed in a 2.0 T scanner using a previously established epilepsy protocol. Images were reviewed, and any abnormality was reported. Patients were divided in those with and without MRI abnormalities. Comparisons were made between these groups concerning age, age at seizure onset, subsyndrome, EEG findings, and seizure control. Results: Of the 134 MRIs evaluated, 33 (24%) showed abnormalities, most of which (88%) were nonspecific. There were eight main abnormalities: arachnoid cyst, diffuse cortical atrophy, basal ganglia abnormalities (signal alterations and prominent perivascular spaces), ventricular abnormalities (uni- or bilateral increased volume of the lateral ventricles), white matter abnormalities (increased T2 signal in the frontal lobes), reduced hippocampal volume, focal gyral abnormality, and area of gliosis in the frontal lobe. Comparisons between the groups showed a higher proportion of EEG focalities in patients with abnormal MRI, which were in most part concordant with the location of the MRI abnormalities. Conclusions: Twenty-four percent of patients with idiopathic generalized epilepsies had MRI abnormalities. However, the majority of these abnormalities were nonspecific.
International Technology Transfer Policies

Concerns are growing about policies and measures that restrict market access with the effect of “forcing” technology transfer. Efforts to target forced technology transfer are complicated by the sometimes blurred line between voluntary and mutually agreed upon technology transfers and that which is perceived to be, or is in fact, compelled. This study presents a discussion of the continuum of measures related to international technology transfer (ITT) and aims to identify those measures that pose the greatest concern over their potential to compel disclosure of commercially valuable and sensitive technology. It then briefly presents information on provisions in international trade and investment agreements that are relevant to ITT. The last section presents the perspective from the private sector in order to better understand how firms engage in technology transfers through research collaboration, licensing, joint ventures, and equity investments. The analysis in this report indicates that involuntary technology transfer is a complex issue, and it aims to provide a way for policy makers to think through the issues, to apply a systematic and analytical approach to assessing which policies are of the greatest concern.
Relationship of Contextual Cueing and Hippocampal Volume in Amnestic Mild Cognitive Impairment Patients and Cognitively Normal Older Adults

Abstract There is currently some debate as to whether hippocampus mediates contextual cueing. In the present study, we examined contextual cueing in patients diagnosed with mild cognitive impairment (MCI) and healthy older adults, with the main goal of investigating the role of hippocampus in this form of learning. Amnestic MCI (aMCI) patients and healthy controls completed the contextual cueing task, in which they were asked to search for a target (a horizontal T) in an array of distractors (rotated L’s). Unbeknownst to them, the spatial arrangement of elements on some displays was repeated thus making the configuration a contextual cue to the location of the target. In contrast, the configuration for novel displays was generated randomly on each trial. The difference in response times between repeated and novel configurations served as a measure of contextual learning. aMCI patients, as a group, were able to learn spatial contextual cues as well as healthy older adults. However, better learning on this task was associated with higher hippocampal volume, particularly in right hemisphere. Furthermore, contextual cueing performance was significantly associated with hippocampal volume, even after controlling for age and MCI status. These findings support the role of the hippocampus in learning of spatial contexts, and also suggest that the contextual cueing paradigm can be useful in detecting neuropathological changes associated with the hippocampus.

Effets bénéfiques de l'activité physique sur la qualité de vie liée à la santé et la corpulence : une approche épidémiologique et évaluative

Les benefices d’une activite physique reguliere sur la sante physique et la qualite de vie ont ete montres dans de nombreuses etudes epidemiologiques, en population malade et generale. Nos objectifs etaient de contribuer aux connaissances sur la relation activite physique et qualite de vie en population generale (adulte, enfant) et de tester l’efficacite de deux modes de fractionnement de l’activite physique hebdomadaire chez les enfants. La mise au point des instruments de mesure d’activite physique (QAPE-semaine) et de qualite de vie (PedsQLTM 4.0) etait un prealable indispensable. Chez les adultes, la pratique d’une activite physique de loisirs est associee a une meilleure qualite de vie, tant dans une approche transversale (dimensions physiques et mentales) que longitudinale (dimension mentale). Un essai randomise en grappe chez les enfants d’âge scolaire a permis de montrer qu’une meme quantite d’education physique et sportive pratiquee a l’ecole ne produisait pas de difference de qualite de vie ou de vitesse d’augmentation de l’indice de masse corporelle, quel que soit le mode de fractionnement et de repartition dans la semaine. La realisation d’un essai randomise permet d’obtenir des resultats convaincants, malgre les difficultes organisationnelles de ces essais en milieu scolaire qui sont discutes. Ils confirment la discordance avec les etudes observationnelles dans lesquelles un lien entre corpulence et fractionnement de l’activite physique peut etre mis en evidence, sans qu’il soit possible de faire la part entre la quantite et la repartition dans la semaine. L’ensemble des resultats, leur implication pour la recherche et la sante publique sont discutes.

Model reference adaptive H∞ control for distributed parameter systems of hyperbolic type by finite dimensional controllers — construction with unbounded observation operator —

The problem of constructing model reference adaptive Hinfin control for distributed parameters systems of hyperbolic type is considered in this paper. The proposed control strategy is composed of finite dimensional compensators, and is derived as a solution of certain Hinfin control problem where spillovers are regarded as external disturbance. Contrary to our previous research, we consider the case where the observation operator is unbounded in the present paper.
Traitement du signal pour les prothèses visuelles: approche biométrique et sensori-motrice

Bien qu'elles existent depuis plus de quarante ans, les protheses visuelles, qu'elles soient invasives (implants) ou non invasive (systemes de substitution sensorielle), n'ont pas perce dans le secteur du handicap. Il serait difficile d'imputer cet etat de fait a des limitations technologiques. Depuis les premieres approches, les protheses visuelles n'ont cesse de se perfectionner et de se diversifier. Toutefois, si la question de savoir comment transmettre le signal est bien documentee, la question de savoir quel signal transmettre a ete plus rarement abordee. Dans cette these, nous identifions des outils susceptibles de pousser la conception des dispositifs de suppleance visuelle au-dela de la seule question de l'interface. Nous puisons pour cela dans les developpements recents sur les theories actives de la vision et dans les implications de ces theories sur la conception et l'evaluation de dispositifs de perception. Nous nous inspirons par ailleurs du fonctionnement des systemes perceptifs naturels, et plus particulierement du traitement de l'information dans le systeme retino-cortical humain, dont nous proposons un modele. Ce modele, issu de plusieurs travaux de these au laboratoire, a fait l'objet d'une simulation logicielle, implementee dans le dispositif de substitution sensorielle visuo-auditif "TheVIBE". L'impact de ce traitement biomimetique du signal est teste experimentalement sur des sujets humains equipes du dispositif dans differentes tâches notamment dans une tâche de mobilite en exterieur. L'observation des strategies mises en oeuvre par les sujets pour se servir du dispositif de substitution permet de formuler de nouvelles hypotheses quant au role du traitement du signal dans le processus de vision.
