Lumped parameter approaches for modeling the cardiovascular system typically have many parameters of which many are not identifiable. The conventional approach is to only identify a small subset of parameters to match measured data, and to set the remaining parameters at population values. These values are often based on animal data or the "average human" response. The problem, is that setting many parameters at nominal fixed values, may introduce dynamics that are not present in a specific patient. As parameter numbers and model complexity increase, more clinical data is required for validation and the model limitations are harder to quantify. This paper considers the modeling and the parameter identification simultaneously, and creates models that are one to one with the measurements. That is, every input parameter into the model is uniquely optimized to capture the clinical data and no parameters are set at population values. The result is a geometrical characterization of a previously developed six chamber heart model, and a completely patient specific approach to cardiac diagnosis in critical care. In addition, simplified sub-structures of the six chamber model are created to provide very fast and accurate parameter identification from arbitrary starting points and with no prior knowledge on the parameters. Furthermore, by utilizing continuous information from the arterial/pulmonary pressure waveforms and the end-diastolic time, it is shown that only the stroke volumes of the ventricles are required for adequate cardiac diagnosis. This reduced data set is more practical for an intensive care unit as the maximum and minimum volumes are no longer needed, which was a requirement in prior work. The simplified models can also act as a bridge to identifying more sophisticated cardiac models, by providing a generating set of waveforms that the complex models can match to. Most importantly, this approach does not have any predefined assumptions on patient dynamics other than the basic model structure, and is thus suitable for improving cardiovascular management in critical care by optimizing therapy for individual patients. © 2009 IFAC.

Spatially-discontinuous Galerkin methods constitute a generalization of weak formulations, which allow for discontinuities of the problem unknowns in its domain interior. This is particularly appealing for problems involving high-order derivatives, since discontinuous Galerkin (DG) methods can also be seen as a means of enforcing higher-order continuity requirements. Recently, DG formulations of linear and non-linear Kirchhoff-Love shell theories have been proposed. This new one-field formulations take advantage of the weak enforcement in such a way that the displacements are the only discrete unknowns, while the C1 continuity is enforced weakly. The resulting one field formulation is a simple and efficient method to model thin structures and can be applied to various computational methods. [less ▲]

We introduce a new algorithm to define a stable Lagrange multiplier space to impose stiff interface conditions within the context of the eXtended Finite Element Method. In contrast to earlier approaches, we do not work with an interior penalty formulation as, e.g., for Nitsche techniques, but impose the constraints weakly in terms of Lagrange multipliers. The new algorithm allows a local construction of the Lagrange multiplier space while improving the accuracy of the computed fields. The originality of this approach with regard to former approaches lies in the use of the trace of primary shape functions defined on the domain, and a simplified procedure to define the mesh on the interface. Moreover, the newly constructed Lagrange multiplier space satisfies, in contrast to the naive approach, a uniform inf-sup condition. [less ▲]

This paper presents the influence of substrate surface preparation on the adhesion strength of repaired beams system. Bond between new and old concrete has been the subject of a number of investigations, but in most cases, only adhesion strength was addressed. This parameter was used to estimate the durability and/or the debonding risk for repaired structure and it’s a generally accepted auditing standards. Usually, surface preparation of the substrate concrete is considered essential to achieve a durable repair because of its influence on the bond strength. To better understand debonding mechanism, in particular these related to surface preparation, roughness parameters were calculated to quantify the influence of surface preparation on the structural behaviour. Using this approach, repair beams prepared by way of four (4) concrete surface preparations were characterized. Results obtained show that repaired beams presenting a substrate with a rough surface permit to achieve a monolithic behaviour of the repaired system. Opposite structural behaviour, with large debonding, was recorded for those having smooth surface. However, all surface preparations used have promoted the same bond strength regardless the roughness of the substrate. The resulting analysis highlights the relation between roughness parameter αrough and the debonding mechanism of repaired beams. Such results will be useful to better predict the performance of concrete repairs. [less ▲]

Electrostatic actuation is often used in microsystems as it is relatively easy to implement and provides a short response time. However, because of the non-linearity of electrostatic forces, these devices may suffer from an unstable behavior called pull-in effect. Previous work of the authors intended to delay pull-in effect by maximizing pull-in voltage studying a simplified problem where the optimization domain was purely mechanical. The present paper generalizes the approach by considering a multiphysic optimization domain. However, the generalization of the optimization problem is not straightforward as local pull-in modes appear after a few optimization iterations. Therefore, the paper investigates several solutions to prevent the appearance of local pull-in modes. [less ▲]

This paper addresses the problem of reactive power dispatch in a power system partitioned into several areas controlled by different transmission system operators. Previous research has shown that nearly optimal performance could be achieved in a time-invariant system by using a specific iterative decentralized control scheme with no information exchange. At each iteration of this scheme, every transmission system operator concurrently schedules its own control settings for the next iteration while representing the neighboring areas with external network equivalents. This paper focuses on some parameter tracking techniques to extend the range of application of the decentralized control scheme to time-varying systems, where the time-varying nature of the system is modeled as a succession of steady-state operating conditions with variation of the load demand. Those new techniques are evaluated in the context of IEEE 118 bus system partitioned into three control areas. [less ▲]

During his Italian journey, which aimed at confirming to Ferrante of Aragon, king of Naples, his elevation to the title of knight of the Golden Fleece, the Bastard Antoine multiplied the visits, the contacts, in Savoy, in Milan twice, in Naples, in the papal court, in Florence, in Venice and in Ferrare. He revealed himself a very pleasant person everywhere he stayed and, in return, was welcomed with the greatest consideration. Whatever may have been, in the name of his brother, the diplomatic relations struck up by the Bastard with the Italian sovereigns, and whatever design they had, either creating an irrepressible strike force against France, or stirring up the most stunning of coalitions against its king by the conclusion of a most politically profitable marital union or by the gift of the Golden Fleece, even if Antoine was able to recruit a few soldiers and weapons, since they took place while the siege of Neuss was dragging on miserably, all these attempts remained in vain in fine. In 1482, the Estates of Burgundy fell to a child and Marie de Bourgogne left behind her a political situation as delicate as the one who prevailed before Sixte IV offered Antoine, by legitimizing him, the dynastic capacity to reign.

Hypothesis / aims of study The aim of this study was to prospectively evaluate the short-term safety and efficacy of the inside-out transobturator sling procedure for treating post-radical prostatectomy (RP) stress urinary incontinence (SUI). Study design, materials and methods The sling technique uses specific instruments and a polypropylene mesh with 2 arms that are passed inside to outside through the obturator foramens, pulled for compressing the bulbar urethra upward, and tied to each other across the midline. Intra-operative urodynamic evaluation is performed to record the urethral pressure profile (UPP) and to measure the abdominal leak point pressure (ALPP) and maximal urethral pressure (MUP) before and after sling tensioning. Urodynamic measurements are repeated until tension on both arms of the mesh increases ALPP to approximately 100 cm H2O. In case of associated urethral stenosis, classic endoscopic urethrotomy is performed first. Inclusion criteria were clinically and urodynamically demonstrated SUI, positive bulbar compression test, and signed informed consent. Patients with detrusor overactivity or active urinary infection were excluded. Baseline evaluation included detailed history, physical examination with a bulbar urethra compression test, urine analysis, multichannel urodynamics, administration of self-questionnaires assessing urinary continence (questions 1 through 3 of the urinary section of the UCLA-PCI-SF questionnaire (1)) and quality of life (QoL) (Ditrovie questionnaire (2)), flexible urethrocystoscopy, and urethrocystography. The degree of incontinence was arbitrarily categorized as mild (1–2 pads/day), moderate (3–5 pads/day) or severe (>5 pads/day), as previously described (3). Follow-up evaluation at 1, 6, 12 months, and yearly thereafter included physical examination, uroflowmetry with PVR measurement, and administration of the self-questionnaires assessing urinary continence and QoL. All patients were also asked to self-evaluate their satisfaction with the treatment. Cure was defined by no pad use and improvement by a number of pads/day ≤ 2 and reduced by at least 50%. Peri- and post-operative complications were recorded. Results From April 2006 through March 2009, 95 consecutive patients who fulfilled inclusion and exclusion criteria underwent the sling procedure using the same operative protocol. As of March 2009, 58 patients who consecutively underwent the sling procedure were expected to have a minimum follow-up of 1 year. Mean age of the patients was 67.6 ± 6.5 years (range 52-79). Mean body mass index was 27.0 ± 3.6 (range 21.3 – 39.0). Of the 58 patients, 9 (16%) patients had undergone prior surgery for SUI: bulking agent injection in 5 patients, prior sling implantation in 1 patient and artificial urinary sphincter (AUS) implantation in 4 patients. A previous urethrotomy or urethral dilatation for urethral stenosis had been performed in 8 (14%) patients and 8 (14%) patients had had pelvic irradiation. Preoperatively, 14 (24%), 26 (45%), and 18 (31%) patients were using 2 (mild SUI), 3 to 5 (moderate SUI), and >5 pads/day (severe SUI), respectively. The sling procedure was performed under general and spinal anesthesia in 22 (38%) and 36 (62%) patients, respectively, and was preceded by an endoscopic urethrotomy in 5 (9%) patients. Penile prostheses were implanted concomitantly to the sling in 2 patients. Before sling tensioning, mean MUP and ALPP were 40 ± 21 cm H2O (range 5-101) and 45 ± 22 cm H2O (range 10-100). After sling tensioning, mean MUP and ALPP were 89 ± 24 cm H2O (range 44-141) and 109 ± 26 cm H2O (range 60-165). Mean increase in MUP and ALPP between post- and pre-tensioning of the sling was 49 ± 29 cm H2O (range 1-125) and 64 ± 32 cm H2O (range 20-135), respectively. Mean operative time was 65 ± 18 minutes. No intra-operative complication was noted. Seven (12%) patients required suprapubic catheterization; normal voiding resumed in all 7 patients except 1 who underwent urinary diversion for complete radiation-induced anastomotic stenosis. Mild perineal hematoma not requiring therapy was observed in 6 patients. Six-month and 1-year minimum follow-up was available on 54 (93%) and 56 (96%) of the 58 patients, respectively (Table 1). Two patients were completely lost to follow-up after the 1-month visit. At this 1-month visit, one patient was cured while the other was improved. Table 1.

In addition, SUI cure/improvement rates appeared to be similar at the 6 and 12 months time points. The 3 failures included one patient who had undergone post-RP radiation therapy. This man later developed a complete urethral anastomotic closure and underwent cystectomy with transileal ureterostomy 9 months after the sling procedure. The two other failed patients had a vesico-urethral anastomotic stricture before sling implantation. Both patients were implanted with an AUS after the sling procedure. After cutting the mesh arms laterally to the bulb, the AUS cuff was placed without difficulty around the bulbar urethra. The 4th failed patient had undergone previous radiation therapy and had a bulbar urethral stenosis. He is now wearing penile collectors. The 5th patient had a vesico-urethral stenosis that underwent urethrotomy just before the sling implantation. The patient has been offered the placement of an artificial urinary sphincter. Preoperative and postoperative max flow rate and postvoid residual values were not different (Table 2). Overall, QoL was substantially enhanced and 85% patients were satisfied with the procedure. Table 2. Postoperative evolution of QoL scores and voiding parameters QoL and voiding parameters Baseline (mean ± SD [range]) 6-month visit (mean ± SD [range]) 1-year visit (mean ± SD [range]) Ditrovie QoL scores (scale from 10 [best] to 50 [worst]) 32 ± 7 (17-50) 16 ± 8 (10-40) 17 ± 8 (10-42) Max flow rate (mL/sec) 20 ± 9 (6-46) 18 ± 9 (6-44) 17 ± 10 (4-51) Post void residual (mL) 17 ± 32 (0-160) 21 ± 51 (0-243) 6 ± 21 (0-87) No sling infection, urethra erosion, persistent pain or neurological complication was observed. No sling was withdrawn or cut. Interpretation of results The inside-out transobturator sling was associated with a minimal risk of intra- and post-operative complications. Postoperative SUI cure/improvement rates were found to remain stable over a 1-year period. The sling procedure appeared to be efficient at short term even in the group of patients with severe SUI before surgery. The sling procedure does not compromise concomitant penile prostheses or subsequent AUS implantation. Longer follow-up times are required to determine the long-term efficacy of this sling procedure. Concluding message The one-year results of this prospective study suggest that the inside-out transobturator sling is a safe and efficient surgical procedure at short term for the treatment of post-RP SUI.

The formulation of macroscopic constitutive laws for the behaviour of masonry is a complex task, due to its strongly heterogeneous microstructure which influences its overall mechanical behaviour. This has triggered in the past decade the formulation of homogenisation methods, both for linear and damaging behaviours, and for in and out-of-plane loading conditions. This contribution deals with two-scale computational framework, in which the material behaviour of a structural masonry shell is sampled by resorting to computational homogenisation applied on a microstructural description of masonry constituents. The structural damaging behaviour is modelled by incorporating localising hinges in a coarse scale thin shell description. The appearance, the orientation and the softening mechanical response of these hinges are directly deduced from the computational homogenisation scheme. This procedure allows incorporating naturally the anisotropic damaging effects of the masonry material degradation. The contribution will illustrate the two-scale results by comparing them to full fine scale models. [less ▲]

Today, many countries of South-East Asia know about the alarming state of the forests existing on their territory and all know that it is essential to save the still existing primary forest but also to enable the regeneration of degraded areas, in particular thanks to reforestation (natural or artificial). To elucidate the role of seed dispersers and to promote their conservation are essential for the conservation of the tropical rainforests. While following a troop of pigtailed macaques (Macaca nemestrina leonina) accustomed to Man in Khao Yai National park (2 168 km ²), Thailand, we will bring important data relating to these seed dispersers potentially necessary but unfortunately vulnerable. Indeed, this species, from which very little has been studied, seems to be essential to the dispersal of many plant species, particularly those inaccessible to smaller frugivores. The results emanating from the first fieldwork already show important characteristics: the dispersal of many seed species, of all kind of size, in all forest types, from primary forest to secondary forest, thanks to various handling techniques. They also seem to show an adaptation in their daily travels according to resources availability. The next fieldworks will enable us to bring more precision in these results and their temporal variations and thus to conclude on the potential role of Macaca nemestrina in the regeneration of the tropical rainforest.

Spatial metrics derived from satellite imagery are useful measures to quantify structural characteristics of expanding cities, and can provide indications of functional land use types. Images of medium resolution are cheap, widely available and are often part of extensive historic archives. Their lower resolution, on the other hand, inhibits studying urban morphology and change processes at a more detailed, intra-urban level. In this study, we develop spatial metrics for use on continuous sealed surface data produced by a sub-pixel classification of Landsat ETM+ imagery. The metrics characterise the shape of the cumulative frequency distribution of the estimated sub-pixel fractions within a building block by fitting an exponential and a sigmoid function with a least-squares approach. A classification tree is then used to relate the metric variables to urban land-use classes selected from the European MOLAND topology. This approach shows promising results, but still needs improvement which may be achieved by including spatially explicit metrics in the analysis. [less ▲]

In today’s urbanising world, effective urban management and planning strategies are needed to temper the impact of urban change processes on the natural and human environment. To develop and monitor such strategies, and to assess their spatial impact, analysing changes in urban structure is essential. Data from earth observation satellites provide regular information on urban development and, as such, may contribute to the mapping and monitoring of cities and the modelling of urban dynamics. Especially images of medium resolution (Landsat, SPOT, …), which are cheap, widely available and often part of extensive historic archives, offer a wealth of information that may be useful for urban monitoring purposes. The lower resolution of this type of imagery, however, hampers the study of urban morphology and change processes at a more detailed, intra-urban level. Spectral unmixing approaches, which allow characterising land-cover distribution at sub-pixel level, may partly compensate for this lack of spatial detail, and may render medium-resolution imagery more useful for urban studies. The main research question addressed in this paper is how medium-resolution imagery could be used to describe urban morphology, by combining spectral unmixing approaches with spatial metrics. Spatial metrics derived from satellite imagery may be useful to quantify structural characteristics of expanding cities, and may provide indications of functional land use. In this study, we develop a set of urban metrics for use on continuous sealed surface data produced by sub-pixel classification of Landsat ETM+ imagery. Two sub-pixel classification approaches are examined for that purpose. In a first approach, we use a linear spectral mixture model with a vegetation and a non-vegetation endmember to deconvolve each pixel’s spectrum into fractional abundances of the two end member spectra, which are determined by visualising mixture space with principal component analysis. In a second approach, we use a linear regression model to estimate the proportion of vegetation cover within each Landsat pixel. In both approaches, an urban mask is used to indicate pixels belonging to urban land cover. Only pixels within the urban mask are subjected to sub-pixel classification. We hereby assume that the urban area does not contain bare soil and that the area of a pixel not covered by vegetation fully consists of sealed surface cover. The resulting sealed surface proportion map is then used to characterise urban morphology and land use by means of the shape of the cumulative frequency distribution of the estimated sealed surface fractions within a building block. A transformed logistic function is fitted to this distribution with a least-squares approach to obtain function parameters that are used as variables in a supervised classification approach, together with spatially explicit metrics (spatial variance and Moran’s I). Our study demonstrates that images from medium resolution sensors can be used to characterise intra-urban morphology, and that the structure of a building block as described by the proposed metrics gives an indication of its membership to certain morphological/functional urban classes. In future research we will incorporate socio-economic data in the metric analysis to further improve the distinction of urban land-use categories. The spatial metrics approach developed in this study will be used in experiments to improve the calibration of the MOLAND urban growth model, which is currently calibrated with historical land-use maps available for approximately 10-year intervals.

Introduction : Un déficit en mémoire épisodique est caractéristique dans la maladie d’Alzheimer (AD) et chez les patients âgés présentant une altération cognitive légère (MCI). Cette altération peut s’expliquer par un déficit d’acquisition et/ou un déficit de consolidation. Toutefois, les modifications cérébrales responsables de ces déficits ne sont pas encore parfaitement élucidées. L’objectif de notre étude était de mettre en relation le profil d’apprentissage déficitaire de ces patients avec leur métabolisme cérébral au repos. Méthode : L’épreuve du California Verbal Learning Test (CVLT) a été administrée à 51 patients AD, 18 patients MCI qui sont restés stables (suivi longitudinal de 18 mois, MCI-S), 16 patients MCI qui ont développé la maladie d’Alzheimer (MCI-C) durant les 18 mois de suivi et 12 participants de contrôle. La mesure d’acquisition est la proportion moyenne de gain à travers les 5 essais d’apprentissage du CVLT. La mesure de consolidation est la proportion totale de pertes à travers ces 5 essais. La mesure du métabolisme cérébral au repos a été effectuée en tomographie par émission de positions (18FDG-TEP). Les mesures de corrélation cognitivo-métabolique ont été réalisées au moyen du logiciel SPM8 (p non-corrigé avec hypothèse a priori <0.001). Résultats : Les groupes AD et MCI-C ont un gain moyen moindre que les groupes MCI-S et contrôles. L’ampleur du gain inter-essais est positivement corrélée à l’activité métabolique au niveau de l’hippocampe postérieur chez les patients AD, à l’activité pariétale inférieure chez les patients MCI-S, et à l’activité frontale postérieure dans le groupe contrôle. Par ailleurs, le groupe AD présente plus de pertes inter-essais que les trois autres groupes. Toutefois, aucune corrélation significative n’apparait entre le total des pertes inter-essais et le métabolisme cérébral. Discussion : Ces données suggèrent que les patients AD, même à un stade très précoce (MCI-C) présentent un déficit d’acquisition de l’information. Ce déficit pourrait être sous-tendu par des perturbations métaboliques dans les réseaux d’apprentissage fronto-pariétaux et hippocampique. Il existe de plus un déficit de consolidation inter-essais spécifique aux patients AD mais ce déficit n’est corrélé à aucune région cérébrale au seuil statistique utilisé. [less ▲]

Crown rot disease of bananas is widespread in producing countries and is considered as the most important post-harvest disease of exported bananas. Variations of susceptibility to the disease have been noted between bananas but the origins still unknown. The biological responses of the fruit, including physiological change and disease susceptibility are controlled and regulated by gene expression. One way to understanding the reactions involved in variation of banana susceptibility to the disease in relation to their physiological state, is to study the expression of genes involved in these processes. To this purpose, crown sample previously inoculated with C. musae and showing 2 levels of susceptibility (very high and very low) were collected to be compared. Crown sample of each susceptibility level was collected at two different maturity stages: at harvest and 13 days after harvest (3 days after ripening). Collected crowns were immediately freeze-dried, an original method to conserve gene expression. cDNA-AFLP was applied on these 4 cell populations in order to highlight the differential transcription of genes whose function is "a priori" unknown. The cDNA-AFLP result was confirmed using quantitative real-time reverse transcription PCR. Various defence-related genes were identified and will be presented. [less ▲]

The rising prevalence of obesity within both industrialized and emerging societies is a major public health problem. Indeed obesity is a usual risk factor in the development of metabolic and cardiovascular diseases which nowadays rank among the highest causes of premature death. Therefore, modulating fat mass expansion represents a worldwide challenge. In this context, adipocyte differentiation, which corresponds to the cellular transition of a fibroblastic cell (the preadipocyte) to a highly specialized cell accumulating triglycerides (the adipocyte), is a decisive process in the expansion of adipose tissue during life span and consequently, in the development of obesity. Adipogenesis markers such as PPARg2, C/EBPa, lipoprotein lipase (LPL), perilipin (PLIN) and the adipokines (leptin and adinopectin) are known to be expressed throughout the different stages of adipocyte differentiation. Guggulsterones are the principal bioactive steroidal components found in the oleoresin (guggul gum) collected from the indian guggul tree, Commiphora mukul (Hook, ex Stocks) Engl. The objective of this study was to investigate the effects of the two purified diastereoisomeric forms of guggulsterones (Z- and E-) on the human preadipocytes proliferation and differentiation.
