This article discusses the application of partial least squares (PLS) for monitoring complex chemical systems. In relation to existing work, this article proposes the integration of the statistical local approach into the PLS framework to monitor changes in the underlying model rather than analyzing the recorded input/output data directly. As discussed in the literature, monitoring changes in model parameters addresses the problems of nonstationary behavior and presents an analogy to model-based approaches. The benefits of the proposed technique are that (i) a detailed mechanistic plant model is not required, (ii) nonstationary process behavior does not produce false alarms, (iii) parameter changes can be non-Gaussian, (iv) Gaussian monitoring statistics can be established to simplify the monitoring task, and (v) fault magnitude and signatures can be estimated. This is demonstrated by a simulation example and the analysis of recorded data from two chemical processes. [less ▲]

Purpose – Fair trade organisations (FTOs) have been taken quite early as examples of Social Enterprises (SE) and have contributed to the shaping of the SE concept. The purpose of this paper is to examine more deeply the link between FTOs and SE, both at a conceptual and at an empirical level. Design/methodology/approach – First, different theoretical frameworks of SE are introduced and confront FT to each of these frameworks. The second step is an empirical study of FTOs across four European countries to illustrate and deepen the links between FT and SE, focusing on the goals and the governance structures of FTOs. Findings – All the FTOs combine in some way economic, social and sometimes also political goals. FTOs are thus coherent to the “hybrid goals” nature of SEs. FTOs' governance is also quite specific and often innovative in terms of organisational architecture and stakeholders' involvement. Some FTOs are closer to the European – participatory – approach while others are closer to US – individual – approaches. Finally, the governance structures of FTOs seem to reflect quite well their goal mix. Research limitations/implications – This paper provides a more solid basis for the often implicit link between FT and SE. Future researches could use this work to explore specific topics of the SE literature in the context of FT (e.g. stakeholders' involvement). The FT example could also be used to examine further the shifting boundaries of the SE reality. Originality/value – The originality of this paper is to apply the SE concept to a specific field and to show how, within this field, there is at the same time a diversity of organisations, reflecting the diversity of SE approaches; and a range of specific features (especially in terms of goal mix and governance) distinguishing SEs from other types of organisations.

BACKGROUND: Cystatin C-based equations are used to estimate GFR. However, three cystatin C immunoassays are on the market. Difference in cystatin C assays could have strong consequences on the accuracy and precision of cystatin C-based equations. We have performed an analytical study of these three assays and studied potential differences between assays on the precision of cystatin C-based equations. METHODS: We have studied imprecision, recovery, linearity and interferences of the three immunoassays (nephelometric assay from Siemens and turbidimetric assays from Dako and Gentian). The impact of differences in cystatin C assays has been studied for the equations published by Levey (Siemens assay) and Grubb (Dako assay). RESULTS: Analytical performance of the Dako assay is slightly less high. For cystatin C values below 2.5 mg/L, no statistical difference is found between results given by the Dako and the Gentian assays. So, both assays can be used in the Grubb equation. Cystatin C results are different with the Siemens assay. The Levey equation, built with the Siemens assay, can only be used with cystatin C values measured with this assay. Using the Dako or Gentian assay results in the Levey equation can lead to differences in estimating GFR up to 6 mL/min/1.73 m2. Differences can reach 9.5 mL/min/1.73 m2 if the Siemens assay is used in the Grubb equation. CONCLUSION: The Siemens and Gentian assays seem analytically more valid than the Dako assay for cystatin C determination. Differences in cystatin C assays can lead to significant differences in cystatin C-based equations. However, these differences seem less important than the differences observed with creatinine and creatinine-based equations. [less ▲]

Generalized Tribonacci morphisms are de ned on a three letters alphabet and generate the so-called generalized Tribonacci words. We present a family of combinatorial removal games on three piles of tokens whose set of P-positions is coded exactly by these generalized Tribonacci words. To obtain this result, we study combinatorial properties of these words like gaps between consecutive identical letters or recursive de nitions of these words. Beta-numeration systems are then used to show that these games are tractable, i.e., deciding whether a position is a P-position can be checked in polynomial time. [less ▲]

With the combination of the enhanced assumed strain (EAS) and assumed natural strain (ANS) techniques in the removal of shear and volumetric locking, the solid-shell formulation requires a minimum set of enhanced modes, and this results in a competitive approach when compared with other fully EAS solid elements in terms of computational costs. Moreover, the latter reportedly suffers difficulties when dealing with very thin plate and shell structures due to the severe transverse shear locking. The paper presents an alternative solid-shell formulation, in which the ANS technique is applied to the upper and lower surfaces instead of at the mid-surface of the solid-shell element as previously adopted. The numerical results show the accuracy and efficiency of the proposed technique. [less ▲]

Atomic layer doping of phosphorus (P) and arsenic (As) into Si was performed using the vapor phase doping (VPD) technique. For increasing deposition time and precursor gas flow rate, the P and As doses tend to saturate at about 0.8 and 1.0 monolayer of Si, respectively. Therefore, these processes are self-limited in both cases. When a Si cap layer is grown on the P-covered Si(001), high P concentration of 3.7 × 1020 cm-3 at the heterointerface in the Si- cap/P/Si-substrate layer stacks is achieved. Due to As desorption and segregation toward the Si surface during the temperature ramp up and during the Si-cap growth, the As concentration at the heterointerface in the Si-cap/As/Si-substrate layer stacks was lower compared to the P case. These results allowed us to evaluate the feasibility of the VPD process to fabricate precisely controlled doping profiles. [less ▲]

Sur base de la littérature, nous voulons faire le point sur ce qui peut être considéré comme une approche standard pour le traitement du cancer du col utérin. Nous évoquerons en particulier les questions suivantes: traitement adjuvant après chirurgie pour les stades précoces, la chirurgie adjuvante après une première chimio-radiothérapie pour les stades avancés, la place de la chimiothérapie néo-adjuvante ainsi que d’autres modalités destinées à augmenter l’effet anti-tumoral des radiations ionisantes. Introduction La prise en charge des cancers dans la sphère gynécologique nécessite une concertation multidisciplinaire ab initio. En effet, différentes approches peuvent être envisagées, et il est primordial de définir avant tout acte thérapeutique la séquence et la synchronisation des différentes modalités afin d’assurer au mieux un succès thérapeutique. La radiothérapie a un rôle central à jouer dans la prise en charge d’une patiente souffrant d’un cancer du col utérin. Une revue non exhaustive de la littérature publiée permet de déterminer sur la base des résultats d’essais randomisés ce qui peut raisonnablement être considéré comme une approche «standard». Cette approche permet aussi de facto de définir quels sont les points d’ombre qui méritent que l’on conduise des essais randomisés dessinés spécifiquement pour répondre à une question précise.

Norine is the first database entirely dedicated to nonribosomal peptides (NRPs). In bacteria and fungi, in addition to the traditional ribosomal proteic biosynthesis, an alternative ribosome-independent pathway called NRP synthesis allows peptide production. It is performed by huge protein complexes called nonribosomal peptide synthetases (NRPSs). The molecules synthesized by NRPS contain a high proportion of nonproteogenic amino acids. The primary structure of these peptides is not always linear but often more complex and may contain cycles and branchings. In recent years, NRPs attracted a lot of attention because of their biological activities and pharmacological properties (antibiotic, immunosuppressor, antitumor, etc.). However, few computational resources and tools dedicated to those peptides have been available so far. Norine is focused on NRPs and contains more than 700 entries. The database is freely accessible at http://bioinfo.lifl.fr/norine/. It provides a complete computational tool for systematic study of NRPs in numerous species, and as such, should permit to obtain a better knowledge of these metabolic products and underlying biological mechanisms, and ultimately to contribute to the redesigning of natural products in order to obtain new bioactive compounds for drug discovery.

From Plato’s dismissal of food as a distraction from thought to Kant’s relegation of the palate to the bottom of the hierarchy of the senses, the sense of taste has consistently been devalued by Western aesthetics. Kant is often invoked as evidence that philosophers consider taste as an inferior sense because it belongs to the realm of the private and subjective and does not seem to be required in the development of higher types of knowledge. From a gastrosophical perspective, however, what Kant perceives as a limitation becomes a new field of enquiry that investigates the dialectics of diet and discourse, self and matter, inside and outside. The essays in this book examine the importance of food as a pivotal element – both materially and conceptually – in the history of the Western avant-garde. From Gertrude Stein to Alain Robbe-Grillet and Samuel Beckett, from F.T. Marinetti to Andy Warhol, from Marcel Duchamp to Eleanor Antin, the examples chosen explore the conjunction of art and foodstuff in ways that interrogate contemporary notions of the body, language, and subjectivity.

Cette contribution présente notre thèse, en se focalisant sur la méthode. Nous avons étudié les relations entre la syntaxe et la ponctuation dans un corpus de chartes originales écrites en français à Liège au treizième siècle. Dans cette recherche, nous avons pris le parti suivant : il est possible de décrire une grande proportion des signes de ponctuation en se servant uniquement d'une approche basée sur l'analyse de la syntaxe (à l'exclusion de la sémantique ou de la visée communicative). Notre étude a nécessité que soient définis précisément les concepts de ponctuation et de syntaxe avant qu'une quelconque analyse puisse être faite. La notion de ponctuation a été définie par rapport à l'ensemble des unités de la langue écrite, que nous avons abordée d'un point de vue autonomiste. Le modèle d'analyse syntaxique a été construit progressivement, d'abord en distinguant la morphologie de la syntaxe, en suite en définissant les types de structures à trois niveaux d'intégration syntaxique différents. Nous avons ensuite employé des outils statistiques pour repérer les structures syntaxiques qui attiraient ou repoussaient la ponctuation. Cette approche outillée nous a permi de sélectionner les points sur lesquels nous avons concentré notre effort descriptif : les associations entre les structures syntaxiques et la ponctuation qui ne semblent pas dues au hasard. Enfin, nous avons examiné la forme des signes à l'aide de méthodes appropriées. [less ▲]
