Vibrational spectroscopy (MIR, NIR and Raman) based hyperspectral imaging is one of the most powerful tools analyze pharmaceutical preparation. Indeed, it combines the advantages of vibrational spectroscopy to imaging techniques and allows therefore the visualization of distribution of compounds, crystallization processes. However, these techniques provide a huge amount of data that must be processed to extract the relevant information. This review presents fundamental concepts of hyperspectral imaging, the basic theory of the most used chemometric tools used to pre-process, process and post-process the generated data. The last part of the present paper focuses on pharmaceutical applications of hyperspectral imaging and highlights the data processing approaches to enable the reader making the best choice among the different tools available.

This paper presents a centralized control scheme, inspired of Model Predictive Control (MPC), to manage thermal overloads and correct abnormal voltages in real-time. The control scheme is able to smoothly bring the system within the desired limits, taking into account its near-future evolution. The control method effectiveness is illustrated on a 20-kV, 32-bus network hosting four distributed generation units. [less ▲]

In this paper, some algorithmic and computational advances are presented for power system dynamic simulations. The heart is a Schur-complement-based solution algorithm, stemming from domain decomposition methods, applied to the differential-algebraic equation model. This algorithm is then accelerated computationally, by employing parallel computing techniques, and numerically, by exploiting time-scale decomposition and localization. Models of a real medium-scale system and a realistic large-scale test system are used for the performance evaluation of the proposed methods. [less ▲]

Hybrid simulations combining phasor-mode and electromagnetic transients models aim at taking advantage of computational speed of the former and accuracy of the latter. For simulation accuracy, a relaxation process is used, which consists of iterating between both models. The convergence properties of this relaxation process are investigated. The speed of convergence is assessed when the variables exchanged at the interface between both models are respectively pure voltage/current sources, Norton/Thévenin equivalents, or a combination of them. Iteratively updated Norton/Thévenin equivalents are shown to drastically reduce the number of relaxation iterations. [less ▲]

In 1994, during the International Conference on Population and Development convened by the United Nations in Cairo, a shocking video was shown, realized by an operator of CNN and depicting the circumcision of a ten-year-old child living in this very same city. Discourses around female circumcision were not new in Egypt and in the international community, but what was considered as a new episode of a recurrent scandal (not the last one indeed) led to enhance the "war against bad government"[1]. A war fought by means of ideological weapons produced by expert knowledges among which the medical and the feminist ones. The assignment of a value to the state of integrity of the female body and to the women freedom of choice, both designed according to Western canons, led to different actions to “save” Egyptian women. In this context, development agencies fosters a widespread representation of the victim, constituted by the woman mutilated body. Such representation is functional to put in place programs which do not guarantee a freedom of choice, but rather require adherence to another female model, one that defines the "modern" woman. My article, based on ethnographic experience, aims at highlighting the complexity of such dynamics and the role played by humanitarianism within them. Female body becomes the arena where local and international economic powers operate, disregarding a real understanding of the practice, its meanings and its eventual change. ________________________________________ [1] Foucault, Michel.

Improving energy efficiency in the building and transportation sectors is a viable approach to mitigate the effects of climate change and has become an important policy target. As a result, in addition to scientific research and public policies addressing energy efficiency, raising public awareness of the impact of the behaviour of citizens to energy efficiency is crucial and could quickly lead to significant reductions in the total energy consumption of a territory. In this context, this paper presents a new online interactive tool that enables not only citizens but also local authorities and private developers to (1) assess the sources of energy consumption related to housing and to daily mobility at both the individual and neighbourhood scales, (2) compare these sources and (3) determine relevant and personalised suggestions to reduce energy consumption. Numerous methods and tools, including a typological classification of buildings, thermal dynamic simulations, life-cycle assessments and statistical treatments of national censuses, were used to produce the two large databases used in this interactive tool. This report represents the primary results of a three-year long scientific research project dedicated to the study of energy efficiency in buildings and for daily mobility that is accessible to a large non-specialised audience.

Intra-luminal fluid and excessive abnormal hyper-edema are regularly used for the diagnosis of endometritis in the mare, which is routinely confirmed by the presence of neutrophils on endometrial smears. Studies show a relation between neutrophils and myeloperoxidase (MPO), an enzyme contained in and released by neutrophils during degranulation or after cell lysis. This enzyme has been found in many fluids and tissues and associated with different inflammatory pathologies in the horse. The aims of this study were to assess the presence and concentration of MPO in the equine uterus, and to investigate its relation with neutrophils, and other clinical signs of endometritis. Mares (n=51) were evaluated for presence of intra-luminal fluid and excessive endometrial edema before breeding, and a small volume lavage and cytology samples were obtained. From 69 cycles, supernatant of the uterine flushes was analysed with a specific equine MPO ELISA assay to measure MPO concentration. Cytology samples were used for the diagnosis of endometritis. MPO was present in the uterus of all estrus mares in highly variable concentrations. MPO concentrations were significantly (p<0.05) higher in samples with positive cytologies and in presence of intra-luminal fluid. Occasionally, some samples with negative cytologies showed high MPO concentration, but the opposite was never observed. Cycles presenting hyper-edema weren’t associated to high concentration of MPO, intra-luminal fluid or positive cytology making it a poor diagnostic tool of endometritis. [less ▲]

Serum creatinine (SCr) is the main variable for estimating glomerular filtration rate (GFR). Due to interassay differences, the prevalence of chronic kidney disease (CKD) varies according to the assay used, and calibration standardization is necessary. For SCr, isotope dilution mass spectrometry (IDMS) is the gold standard. Systematic differences are observed between Jaffe and enzymatic methods. Manufacturers subtract 0.30 mg/dl from Jaffe results to match enzymatic results (‘compensated Jaffe method’). The analytical performance of enzymatic methods is superior to that of Jaffe methods. In the original Modification of Diet in Renal Disease (MDRD) equation, SCr was measured by a Jaffe Beckman assay, which was later recalibrated. A limitation of this equation was an underestimation of GFR in the high range. The Chronic Kidney Disease Epidemiology (CKD-EPI) consortium proposed an equation using calibrated and IDMS traceable SCr. The gain in performance was due to improving the bias whereas the precision was comparable. The CKD-EPI equation performs better at high GFR levels (GFR[60 ml/ min/1.73 m2). Analytical limitations have led to the recommendation to give a grade ([60 ml/min/1.73 m2) rather than an absolute value with the MDRD equation. By using both enzymatic and calibrated methods, this cutoff-grade could be increased to 90 ml/min/1.73 m2 (with MDRD) and 120 ml/min/1.73 m2 (with CKD-EPI). The superiority of the CKD-EPI equation over MDRD is analytical, but the precision gain is limited. IDMS traceable enzymatic methods have been used in the development of the Lund– Malmo¨ (in CKD populations) and Berlin Initiative Study equations (in the elderly). The analytical errors for cystatin C are grossly comparable to issues found with SCr. Standardization is available since 2011. A reference method for cystatin C is still lacking. Equations based on standardized cystatin C or cystatin C and creatinine have been proposed. The better performance of these equations (especially the combined CKD-EPI equation) has been demonstrated.

The Childhood Executive Functioning Inventory (CHEXI) is a new rating instrument for executive functioning developed by Thorell and Nyberg (2008). Through exploratory factor analyses, this inventory has been shown to tap into working memory and inhibition-related behaviors in young children. In this study, we present the psychometric characteristics of the French adaptation of the CHEXI in 8- to 11-year-old children. In addition, we explore the cross-cultural validity of the CHEXI in discriminating between children with ADHD and normally developing children in two culturally different samples (Belgian and Swedish). Confirmatory factor analyses replicated the two-factor solution, referred to as inhibition and working memory, that was identified in the original study with Swedish children. Supplementary analyses indicated that both subscales have good psychometric properties. From a clinical point of view, the CHEXI was found to discriminate, with high sensitivity and specificity, between children with ADHD and normally developing controls in both cultural samples. Cross-cultural clinical implications are discussed. [less ▲]
