In the Diagnostic Classification Zero to Three, Regulation Disorders of Sensory Processing refer to children’s difficulties in regulating emotions, behaviours and motor skills in response to sensory stimulation. This article presents a research program that aims to specify more accurately the semiology of micro-signs – identifiable¬ in the clinical symptoms and in anamnesis – of¬ Regulation Disorders. We give here the results of a preliminary stage of research, which consists of a qualitative microanalysis of 90 Regulation Disorder cases in children between 7 months and 5 years old. We give particular attention to visual-spatial processing, auditory-verbal processing, the perception of the affects, the modalities of their expression, the “energy level” of the child, the organisation of the buccal sphere, the hyper- or hyposensitivity of each sensory channel, and all symptoms having a connection to some constitutional platform. This preliminary stage serves as the basis of a questionnaire which is at heart of the second step of the research. We will further clarify the specific signs of Regulation Disorders and their frequency, comparing the results of this anamnestic questionnaire using a control sample and a sample of children with Regulation Disorders. This study aims to contribute to a more accurate description of the clinical pictures of these children and to enrich multidisciplinary exchanges and psychotherapeutic practices. [less ▲]

In 1994 was published the first « Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood », and in August 2005 the Revised Edition » (DC:0-3R). This article presents the revised criteria of the diagnosis: Regulation Disorders of Sensory Processing. This innovative diagnosis includes three types: Hypersensitive, Hyposensitive/Underresponsive and Sensory Stimulation-Seeking/Impulsive. These children have difficulty processing sensory input (touch, sight, sound, taste, smelt, sensation of movement) and regulating their responses. This diagnosis refers to children’s difficulties in regulating emotions, behaviours and motor abilities in response to sensory stimulation. [less ▲]

The k-means method is used in classification to group similar observations in k groups. When a second sample is available to test the obtained groupings, the rate of misclassification can be computed. If the samples are generated from a mixture of two homoscedastic and spherically symmetric distributions, the rate of misclassification equals that of the Bayes rule. Therefore, the k-means method is optimal under such a mixture model. However, it is not robust with respect to outliers in the dataset used to construct the groups. To avoid this problem, the k-means procedure has been adapted in many ways. This presentation focuses on the trimmed k-means method defined by trimming some of the observations. The advantage of this method, besides its resistance to outliers, is that optimality is preserved. However, it is well known that trimming observations leads to a loss in classification efficiency. The latter can be measured by means of the influence function of the misclassifiation rate. [less ▲]

Pour aborder le traitement chirurgical de la valvule mitrale autrement, c'est-à-dire par une réparation valvulaire comme alternative raisonnable au remplacement sytématique, il faut recourir à une classfication fonctionnelle des dysfonctions mitrales. Cette classification, établie par Carpentier (1, 2) regroupe les dysfonctions valvulaire mitrales en trois rubriques : a) le type caractérisé par des mouvements valvulaires normaux, b) le type 2, équivalent au prolapsus valvulaire, c) le type 3, correspondant à la restriction des mouvements valvulaires. Cette approche nouvelle postule, en outre, qu'une affection valvulaire n'est parfaitement définie que lorsqu'on en connaît l'étiologie, les lésions et les dysfonctions. L'utilisation de cette méthode analytique (qui a l'avantage de la simplicité et de la clarté) permet au chirurgien de réparer la valvule mitrale en adaptant à chaque dysfonction une correction appropriée et, par l'application de règles, d'obtenir des résultats reproductibles (3-6).

This study develops a method classifying retail spaces through geometry. It attempts to objectify quantitatively several criterions (usually based on empirical observation) which define retail supply. The method developed shows that it is possible to characterize different commercial forms by using relatively simple indicators. In order to apply this method, this study drawn upon a database of 20,000 stores geolocalised and gathered by shopping areas all over Wallonia. This paper is divided into three main points: the construction of indicators, their compilation and the identification of a classification of retail spaces. [less ▲]

BACKGROUND: Percutaneous coronary intervention (PCI) of coronary bifurcation lesions remains a subject of debate. Many studies have been published in this setting. They are often small scale and display methodological flaws and other shortcomings such as inaccurate designation of lesions, heterogeneity, and inadequate description of techniques implemented. METHODS: The aim is to propose a consensus established by the European Bifurcation Club (EBC), on the definition and classification of bifurcation lesions and treatments implemented with the purpose of allowing comparisons between techniques in various anatomical and clinical settings. RESULTS: A bifurcation lesion is a coronary artery narrowing occurring adjacent to, and/or involving, the origin of a significant side branch. The simple lesion classification proposed by Medina has been adopted. To analyze the outcomes of different techniques by intention to treat, it is necessary to clearly define which vessel is the distal main branch and which is (are) the side branche(s) and give each branch a distinct name. Each segment of the bifurcation has been named following the same pattern as the Medina classification. The classification of the techniques (MADS: Main, Across, Distal, Side) is based on the manner in which the first stent has been implanted. A visual presentation of PCI techniques and devices used should allow the development of a software describing quickly and accurately the procedure performed. CONCLUSION: The EBC proposes a new classification of bifurcation lesions and their treatments to permit accurate comparisons of well described techniques in homogeneous lesion groups. [less ▲]

Symmetries play a crucial role in electroweak symmetry breaking models with non-minimal Higgs content. Within each class of these models, it is desirable to know which symmetry groups can be implemented via the scalar sector. In N-Higgs-doublet models, this classification problem was solved only for N=2 doublets. Very recently, we suggested a method to classify all realizable finite symmetry groups of Higgs-family transformations in the three-Higgs-doublet model (3HDM). Here, we present this classification in all detail together with an introduction to the theory of solvable groups, which play the key role in our derivation. We also consider generalized-CP symmetries, and discuss the interplay between Higgs-family symmetries and CP-conservation. In particular, we prove that presence of the $Z_4$ symmetry guarantees the explicit CP-conservation of the potential. This work completes classification of finite reparametrization symmetry groups in 3HDM. [less ▲]

This work focuses on the experimental classification of flow patterns in rectangular shallow reservoirs, including symmetric flows without any reattachment point to asymmetric flows with one reattachment point, two reattachment points, or two reattachment points and one detachment point. The median position and the natural variability of the reattachment lengths of asymmetric flows were measured for forty geometric and hydraulic conditions. The effects of dimensionless flow depth, Froude number, lateral expansion ratio and dimensionless length on the median reattachment lengths were analyzed. A number of regression equations were proposed. For “high” dimensionless flow depths and a Froude number of 0.20, a shape parameter was proposed for predicting the transition between symmetric and asymmetric flows. The results of this study are useful knowledge for improving current methods to predict the trapping efficiency and the preferential regions of deposition in reservoirs. [less ▲]

Groundwater chemistry in groundwater-fed wetlands often is the result of mixing of discharging groundwater and rainfall in combination with chemical reactions altering the chemical composition, mostly due to changes in redox conditions. In this study, a Self-Organizing Map is used to classify chemical groundwater samples of three groundwaterfed wetlands in Belgium in order to identify the origin of groundwater and to deduce redox conditions in the wetlands. The Self-Organizing Map (SOM) algorithm is an unsupervised neural network technique to represent a multidimensional dataset on a two-dimensional grid in a topology-preserving way, allowing investigation of non-linear, complex relationships between variables and grouping of the data (Kohonen, 1995). The SOM is trained with data from a regional groundwater monitoring network and rainfall data. The resulting SOM is able to distinguish between samples of different origin or redox conditions within the regional aquifers. Subsequently, samples of the three wetlands are shown to the SOM and each sample is classified as having a chemical composition comparable to rainfall or to one of the regional aquifers. [less ▲]

Brazilian iron ores are predominantly hematitic and may have different textures. In the mining industry, their microstructural characterization is manually performed, by analyzing samples under an optical microscope to identify the hematite textures and estimate their fractions and crystal size. This procedure is subjective and consequently susceptible to random and systematic errors. The present paper proposes an automatic method for the identification, measurement and classification of hematite crystals in iron ore according to their textural types. The method exploits the use of circularly polarized light to amplify brightness and color differences among hematite crystals, allowing their individualization, and the subsequent morphological analysis and classification into granular, lamellar or lobular classes. The classifier was tested with more than 5400 crystals, reaching a global success rate close to 98%, and success rates per class above 96%. [less ▲]

This study’s aim was to measure the advantages of using psychological test data in the automatic classification of functional brain images in order to assist the diagnosis of neurodegenerative disorders such as Alzheimer’s disease (AD). Several computer-aided diagnosis systems for AD based on PET images were developed. Some of them used psychological scores beside the image data in the classification step and others did not. The results show the ones that take into account the psychological scores achieve higher accuracy rates. [less ▲]
