Paramétrisation et optimisation sans dérivées pour le problème de calage d'historique. (Parametrization and derivative free optimization for the history matching problem)

Dans cette these, on s’interesse a un probleme inverse classique en ingenierie petroliere, asavoir le calage d’historique. Plus precisement, une nouvelle methode de parametrisation geostatistiqueainsi qu’un nouvel algorithme d’optimisation sans derivees adaptes aux particularitesdu probleme sont presentes ici. La nouvelle methode de parametrisation repose sur les principes des methodes de deformation graduelle et de deformation de domaines. Comme la deformation graduelle locale, elle consiste acombiner a l’interieur de zones prealablement definies deux realisations ou plus de modele avec lapossibilite supplementaire de modifier dynamiquement la forme des zones choisies. La flexibiliteapportee par cette methode dans le choix des zones a ainsi permis de garantir l’obtention d’unbon point initial pour l’optimisation. Concernant l’optimisation, l’hypothese que les parametres locaux dans le modele de reservoir n’influent que faiblement sur les donnees de puits distants conduit a considerer que la fonction aoptimiser est a variables partiellement separables. La nouvelle methode d’optimisation developpee,nommee DFO-PSOF, de type region de confiance avec modele quadratique d’interpolation,exploite alors au maximum cette propriete de separabilite partielle. Les resultats numeriquesobtenus sur plusieurs cas de reservoir valident a la fois l’hypothese effectuee ainsi que la qualitede l’algorithme pour le probleme de calage d’historique. En complement de cette validation numerique,un resultat theorique de convergence vers un point critique est prouve pour la methoded’optimisation construite
A background gain- calibration technique for low voltage pipelined ADCs based on nonlinear interpolation

In the design of green circuit, the most effective way for low power is to reduce the supply voltage. However, the accuracy of pipelined ADC is limited by the residue amplification. The inaccurate residue amplification is much worse in an ultra-low voltage condition because of the lack of the headroom for transistors in the opamp. This paper describes a new background calibration technique for the pipelined ADCs designed in the ultra-low supply voltage. Based on the Least Mean Square (LMS) algorithm and the digital nonlinear interpolation, the proposed calibration technique corrects the interstage gain error. It is a fully digital approach and only needs very little analog modifications, which increases the design flexibility and reduces the production cycle.
Postoperative Radiographic Evaluation After Acoustic Neuroma and Glomus Jugulare Tumor Removal

The role of postoperative radiographic follow-up of patients after acoustic neuroma or glomus jugulare tumor removal is unclear and not standardized. The incidence of both lesions is rare and recurrence thought to be unusual. However, a patient with an acoustic neuroma arising in the same ear afflicted with a glomus jugulare tumor removed 5 years earlier prompted a retrospective review of 999 acoustic neuroma and 98 glomus jugulare tumor patients. This review helps to determine the role and frequency of postoperative follow-up, not only to assess recurrence of these lesions but to monitor for the possible development of potential clinically silent new lesions.
Falling in love: Prospective studies of self-concept change.

Two prospective, longitudinal studies examined the consequences of falling in love, focusing on predictions developed in the context ofA. Aron and E. N. Aron's (1986, in press) self-expansion model of motivation and cognition in close relationships. In each study a sample with a high expected incidence of falling in love (first- and second-year undergraduates in the fall term) was tested 5 times over 10 weeks. At each testing participants indicated whether they had fallen in love and either made open-ended lists of self-descriptive terms (Study 1 ; N = 329) or completed standard self-efficacy and self-esteem measures (Study 2 ; N = 529). As predicted, after falling in love there was greater change and increased diversity of self-concept domains (Study I) and increased self-efficacy and self-esteem (Study 2). Partial correlation analyses suggested that results in both studies were not due to mood change.
Effect of bone mineral guideline target achievement on mortality in incident dialysis patients: an analysis of the United Kingdom Renal Registry.

BACKGROUND Abnormalities in bone mineral metabolism parameters are common in patients with end-stage kidney disease on dialysis therapy. The National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines propose targets for calcium, phosphate, and intact parathyroid hormone (iPTH) levels in patients undergoing dialysis. However, whether achievement of these targets improves survival is unknown. STUDY DESIGN Retrospective cohort study. SETTING & PARTICIPANTS Incident patients on hemodialysis or peritoneal dialysis therapy in the United Kingdom from 2000-2004 who survived at least 12 months. PREDICTOR Achievement of KDOQI calcium, phosphate, and iPTH guideline targets during the first year of dialysis therapy. OUTCOMES All-cause mortality in the subsequent 2 years. MEASUREMENTS Calcium, phosphate, and iPTH at quarterly intervals, demographic and comorbid condition data at baseline. RESULTS We included 7,076 incident patients (4,947 hemodialysis, 2,129 peritoneal dialysis) in our analysis. Approximately two thirds of patients were men and 21% had diabetes as the cause of kidney failure. Guideline target achievement for each quarter varied from 23%-26% for iPTH level, 43%-47% for calcium level, and 54%-62% for phosphate level targets. In adjusted Cox proportional hazards models, patients who achieved guideline targets in all 4 quarters did not have a survival advantage over patients who never achieved target (P > 0.1 for calcium, phosphate, and iPTH). LIMITATIONS Missing information about medication use, vitamin D and alkaline phosphatase levels, and dialysate calcium content. CONCLUSIONS Our findings do not support the use of KDOQI bone mineral guideline achievement as a quality measure for dialysis care. Prospective studies with longer term follow-up are needed to define the optimal cutoff values for calcium, phosphate, and iPTH and assess the effect of guideline implementation on patient survival.
Coverage performance of UWB in-car wireless communication in the presence of multiple terminals

Recent years, the increase in complicated wire harness increases the weight and consequently harms the environment friendliness especially in a luxury car. Therefore, it is expected that in-car network is effectively built by using wireless connection as well as wired connection. In this paper, we investigate the coverage area performance of MB-OFDM UWB in-car communication in the presence of plural mobile terminals. In our approach, simultaneous multi-user wireless transmission is realized by multi-user MIMO (MU-MIMO) employing linear precoding with restriction of the total transmit power which satisfies the UWB power density limitation. Numerical results show the influence of the number of terminals on the coverage area under in-car propagation and verify the applicability of MU-MIMO to MB-OFDM UWB in-car wireless communication.

Experimental Methodology and Theory-Building in Mathematical Psychology

An inquiry is made into the directions that theory-building in psychology might be taking with respect to the new trend in experimental methodology generated by mathematical models, concept-learning studies, and studies in individual differences. The implications of nomological theories, informal theories, and modeling activities with respect to this trend are analyzed in general, and an integrative description is developed. Particular attention is given to the problems presented by the use of isomorphism as the implicit justification for this methodology. This paper attempts to outline some basic issues in theory-building which seem in need of clarification.
Ability and Role Clarity as Enhancers of the Expectancy Theory Model

This study investigated whether the inclusion of ability or role clarity could increase the predictiveness of the traditional expectancy theory model, i.e., effort = expectancy × instrumentality × valence. Both variables had an effect, but the influence of ability was much greater than that of role clarity in a sample of 285 undergraduates.
Maximum Lifetime Routing In Wireless Sensor Networks ∗

We show that the problem of routing messages in a wireless sensor network so as to maximize network lifetime is NP-hard. In our model, the online model, each message has to be routed without knowledge of future route requests. We develop also an online heuristic to maximize network lifetime. Our heuristic, which performs two shortest path computations to route each message, is superior to previously published heuristics for lifetime maximization– our heuristic results in greater lifetime and its performance is less sensitive to the selection of heuristic parameters. Additionally, our heuristic is superior on the capacity metric.
Learning the Language of Practice

ABSTRACTThis article describes learning to teach as a task involving learning to think and act in ways appropriate to the demands of the profession—a task referred to as “learning the language of practice. ” The language of practice is described using common sense and practical analyses of knowledge and action. A study of student teachers is presented to illustrate processes and concepts involved in acquiring a language of practice. The paper concludes with a description of a pattern language developed in the field of architecture and a discussion of its implications for a descriptive language of teaching.
Whole-genome trees based on the occurrence of folds and orthologs: implications for comparing genomes on different levels.

We built whole-genome trees based on the presence or absence of particular molecular features, either orthologs or folds, in the genomes of a number of recently sequenced microorganisms. To put these genomic trees into perspective, we compared them to the traditional ribosomal phylogeny and also to trees based on the sequence similarity of individual orthologous proteins. We found that our genomic trees based on the overall occurrence of orthologs did not agree well with the traditional tree. This discrepancy, however, vanished when one restricted the tree to proteins involved in transcription and translation, not including problematic proteins involved in metabolism. Protein folds unite superficially unrelated sequence families and represent a most fundamental molecular unit described by genomes. We found that our genomic occurrence tree based on folds agreed fairly well with the traditional ribosomal phylogeny. Surprisingly, despite this overall agreement, certain classes of folds, particularly all-beta ones, had a somewhat different phylogenetic distribution. We also compared our occurrence trees to whole-genome clusters based on the composition of amino acids and di-nucleotides. Finally, we analyzed some technical aspects of genomic trees-e.g., comparing parsimony versus distance-based approaches and examining the effects of increasing numbers of organisms. Additional information (e.g. clickable trees) is available from http://bioinfo.mbb. yale.edu/genome/trees.
National symptom surveillance using calls to a telephone health advice service--United Kingdom, December 2001-February 2003.

INTRODUCTION Recent terrorist activity has highlighted the need to improve surveillance systems for the early detection of chemical or biologic attacks. A new national surveillance system in the United Kingdom (UK) examines symptoms reported to NHS Direct, a telephone health advice service. OBJECTIVES The aim of the surveillance system is to identify an increase in symptoms indicative of early stages of illness caused either by a deliberate release of a biologic or chemical agent or by common infections. METHODS Data relating to 10 key syndromes (primarily respiratory and gastrointestinal) are received electronically from 23 call centers covering England and Wales. Data are analyzed daily and statistically significant excesses, termed exceedances, in calls are automatically highlighted and assessed by a multidisciplinary team. RESULTS During December 2001-February 2003, a total of 1,811 exceedances occurred, of which 126 required further investigation and 16 resulted in alerts to local or national health-protection teams. Examples of these investigations are described. CONCLUSION Surveillance of call-center data has detected substantial levels of specific syndromes at both national and regional levels. Although no deliberate release of a biologic or chemical agent has been detected thus far by this or any other surveillance system in the UK, the NHS Direct surveillance system continues to be refined.
Psychological adjustment among pediatric cancer survivors.

SUMMARY A significant number of children who survive pediatric cancer experience residual psychosocial sequelae. The most noteworthy of these include residual depression, anxiety, and poor self-esteem. As a group, those patients who have the most difficulty in psychosocial adjustment also have less effective socialization and self-help skills and less effective intellectual functioning than do those patients who have “Good Adjustment”. The developmental disruptions engendered by cancer treatment seem more marked and persistent when occurring in middle childhood or adolescence as opposed to during infancy. As one gets further in time from the onset of the illness, one is less likely to suffer psychosocial adjustment problems (assuming that a disease-free remission state exists and that active treatment is no longer in progress). A number of important factors remain to be explored, including psychosocial adjustment as a function of residual physical disfigurement, mobility handicaps, and similar potential blows to a patient's sell-esteem.
White Matter Degeneration with Aging: Longitudinal Diffusion MR Imaging Analysis.

PURPOSE To determine longitudinally the rate of change in diffusion-tensor imaging (DTI) parameters of white matter microstructure with aging and to investigate whether cardiovascular risk factors influence this longitudinal change. MATERIALS AND METHODS This prospective population-based cohort study was approved by a dedicated ethics committee overseen by the national government, and all participants gave written informed consent. Community-dwelling participants without dementia were examined by using a research-dedicated 1.5-T magnetic resonance (MR) imager on two separate visits that were, on average, 2.0 years apart. Among 810 persons who were eligible for imaging at baseline, longitudinal imaging data were available for 501 persons (mean age, 69.9 years; age range, 64.1-91.1 years). Changes in normal-appearing white matter DTI characteristics in the tract centers were analyzed globally to investigate diffuse patterns of change and then locally by using voxelwise multilinear regression. The influence of cardiovascular risk factors was assessed by treating them as additional determinants in both analyses. RESULTS Over the 2.0-year follow-up interval, global fractional anisotropy (FA) decreased by 0.0042 (P < .001), while mean diffusivity (MD) increased by 8.1 × 10(-6) mm(2)/sec (P < .001). Voxelwise analysis of the brain white matter skeleton showed an average decrease of 0.0082 (Pmean = .002) in FA in 57% of skeleton voxels. The sensorimotor pathway, however, showed an increase of 0.0078 (Pmean = .009) in FA. MD increased by 10.8 × 10(-6)mm(2)/sec (Pmean < .001) on average in 79% of white matter skeleton voxels. Additionally, white matter degeneration was more pronounced in older persons. Cardiovascular risk factors were generally not associated with longitudinal changes in white matter microstructure. CONCLUSION Longitudinal diffusion analysis indicates widespread microstructural deterioration of the normal-appearing white matter in normal aging, with relative sparing of sensorimotor fibers.
Combining Behavioral Theories to Predict Recycling Involvement

This study merges insights from two well-known attitude-behavior theories—the theory of planned behavior and the model of altruistic behavior—with elements from two broader models from environmental psychology—the model of environmental behavior and the model of environmental concern—to propose a comprehensive structural equation model to explain recycling behavior. The specified model is estimated using data from the most recent national survey performed in Portugal on the subject. In general, results support the use of the theory of planned behavior as a basis for modeling recycling participation. However, the integration of this theory with the Schwartz's model is only partially achieved. Another important finding is that recycling behavior is indirectly determined by personal psychological features, such as social conscience, but not by general ecological attitudes.
Lesson Planning in Primary School Using Lesson Study and Open Approach

Lesson plans are generally written in a way that helps teachers to layout and run classroom activities. Many researchers have examined how teachers go about planning. This clearly shows that instructional plans play a central role in teaching and creating effective learning environments (Clark & Dunn, 1991; Reiser & Dick, 1996; Shauelson, 1983 cited in Koszalka et al., 1999). In context of school using lesson study and open approach followed conception of Inprasitha (2010), the importance of lesson study processes is collaborative lesson planning. After that the teachers who participate in lesson study group use these lesson plans in the classroom, observe and collect students’ thought and learning processes. And in planning the lessons use problems that students encounter in everyday life, so as to stimulate students to work to achieve the objective (Fernandez & Yoshida, 2004). The data were collected by video and audio recording while the target group were planning and teaching the lessons in lesson study process, then were transcribed to the protocol and analyzed by using theoretical framework of Stigler and Hiebert (1999). The research revealed that the target group discussed during the lesson planning process detailing about exact words, problem situations, materials, the anticipated solutions, students’ thoughts and responses, time used in each part of the lesson, and how to summarize the lesson. In the lesson planning, the exact words used in the problem situations were mostly mentioned. Moreover, in lesson planning, the issue of details of introduction design was discussed a lot. There were some issues which were not discussed during the teachers-included designing of the lesson plan. However, they were discussed while the teacher was using the lesson plan in class during instructional management.
Simulating Continous Systems with Piecewise - Linear Signals Using Time Warp

Recently, an approach using the discrete event paradigm for the simulation of continuous systems has been developed. This approach is based on the use of piecewise-linear approximations for the representation of continuous, time-varying quantities. The focus of this paper is to show how this new technique can be implemented on a multiprocessor. Our hypothesis is that the Time Warp algorithm is the natural protocol for parallel simulation using continuous, piecewise-linear signals. We have implemented a prototype simulator and measured its performance on a multiprocessor using several benchmarks. On the basis of these benchmarks we show that the best performance is achieved when using a scheduling algorithm that gives priority to messages with lower timestamps and when the lazy-cancellation variant of Time Warp is used. In this case, the performance of our prototype simulator compares quite favourably with the estimates of optimum performance based on a critical path analysis of the sequential simulation. In fact, our results indicate that in certain cases the performance of the Time Warp algorithm using lazy cancellation can exceed the conservative optimum estimate obtained from the critical path analysis.
Emergency department predictors of posttraumatic stress reduction for trauma-exposed individuals with and without an early intervention.

OBJECTIVE Recent data have supported the use of an early exposure intervention to promote a reduction in acute stress and posttraumatic stress disorder (PTSD) symptoms after trauma exposure. The present study explored a comprehensive predictive model that included history of trauma exposure, dissociation at the time of the trauma and early intervention, and physiological responses (cortisol and heart rate) to determine which variables were most indicative of reduced PTSD symptoms for an early intervention or treatment as usual. METHOD Participants (n = 137) were randomly assigned to the early intervention condition (n = 68) or assessment-only condition (n = 69) while receiving care at the emergency department of a Level 1 trauma center. Follow-up assessments occurred at 4 and 12 weeks posttrauma. RESULTS Findings suggested that dissociation at the time of the 1st treatment session was associated with reduced response to the early intervention. No other predictors were associated with treatment response. For treatment as usual, cortisol levels at the time of acute care and dissociation at the time of the traumatic event were positively associated with PTSD symptoms. CONCLUSIONS Dissociation at the time at which treatment starts may indicate poorer response to early intervention for PTSD. Similarly, dissociation at the time of the event was positively related to PTSD symptoms in those who received treatment as usual.
One mouth and two breasts – The ground plan of triangulation: A baby fed on one breast only

Abstract The infant observation material of a baby fed on one breast only led to thinking about collateral experiences inherent in the normal bilateral breast-feeding situation, such as the infant's perception of the symmetry of his own and his mother's body, and the tridimensional visual, auditory and tactile experience of his mother's presence. Further thought is given to the numerous triangulations which are shaped spontaneously at the part-object level in the interaction between mother and baby. The material shows the particular difficulties of the weaning process, but reveals also how this baby who had missed the full experience at the breast created in his play more and more meaningful configurations which showed that he had been able to keep alive the preconception of the twoness of the breasts and other double body parts, and thereby to ‘nourish’ his mind with positive realizations which he could introject.
