Brain Tumor Segmentation Using Biography Based Neural Clustering ( BBNC ) And Genetic Processing For Medical Images

This research shows the segmentation of medical images. The segmentation of the medical images (MRI, CT) or can say for extracting a particular region of tumor in the medical images is a challenging task in medical field. Computed Tomography (CT) and Magnetic Resonance Images (MRI) are the high resolution strategies to locate the brain tumor. That is why to apply the soft computing methods on CT and MRI is complex and time consuming process. This paper presents the survey for different types of segmentation techniques and propos a new technique named biography based neural clustering (BBNC). In the proposed methodology the arrangements of different tissues with high complexity can be observed by applying preprocessing methods and genetic filtering etc. Then it will demonstrate the output of the proposed genetic filtering. By applying the clustering system on the MRI and CT, the mapping of tumor and malefic tissues can be done. This system also can be used for genetic bounding to find the area and pixel based concentration of the required region by applying the biography based neural clustering and genetic processing on that images. This research will presents an extension to the existing segmentation algorithm that modifies the deformable registration of pre operative and post-recurrence brain MRI scans. The new technique handles different sorts of pathology, space-occupying mass tumors based on details varying due to contrast and non-contrast imaging, noisy environment, low quality resonance and sampling effects. Keywords—Medical Images,Segmentation Techniques, Image Analysis and preprocessing, genetic processing, neural clustering.
Detection and Analysis of Protein‐Protein Interactions of Organellar and Prokaryotic Proteomes by Blue Native and Colorless Native Gel Electrophoresis

Native gels enable the analysis of protein complexes on a proteome‐wide scale in a single experiment. The protocols described in this unit are based on separation of protein complexes by blue native polyacrylamide electrophoresis (BN‐PAGE), the most versatile native gel system, and the closely related milder colorless native PAGE (CN‐PAGE). Both BN‐PAGE and CN‐PAGE are described on analytical to preparative scales. In addition, methods for subsequent analysis of protein complexes are given, including electroelution from native gels as well as denaturing and native two‐dimensional PAGE. Finally, the removal of Coomassie dye from electroeluted proteins is detailed along with a discussion of fundamental considerations for the solubilization of membrane protein complexes from various biological samples, which are exemplified for mitochondria, chloroplasts (thylakoids), and cyanobacteria.

MORPHOMETRIC DATA ABOUT SEED COAT ORNAMENTATION WITH TAXONOMIC CONSIDERATIONS IN JOVIBARBA HEUFFELII (CRASSULACEAE) POPULATIONS FROM SOUTHERN CARPATHIANS

The seed coat ornamentation pattern was generally used in the systematics of other Crassulacean genera. Previous work showed a considerable variation of this character within the genus Jovibarba Opiz. In this paper it was investigated by optical and electron microscopy SEM the seed coat ornamentation constancy among 9 Romanian populations of Jovibarba heuffelii (Schott) A&D Love to evaluate the infraspecific reliability of this character. Morphometric data and SEM micrographs of a representative seed coat and ornamentation details are presented about the Romanian material, showing homogeneity of seed size, shape and pattern. The seed coat shows a more or less irregular network of crisscrossing longitudinal and transversal broken ridges, without constant cell pattern or any wart-like protuberances but fitting the general characters of Knapp's "Leitermodel". Although quite homogeneous within the populations examined by us, the Romanian matenal departs from the "Jovibarba Type" a.3. pattern reported by Knapp, being rather similar to the a.3. "Net structure" he described in Orostachys japonicus, but with sinuous longitudinal ridges exceeding 20 per seed. The dissimilarity with Knapp's "Jovibarba Type" existing in the Romanian populations suggests that the seed coat morphology has a considerable intraspecific variation between distant populations, a fact that could not be neglected when assessing its taxonomic value even at infraspecific level.
Succession processes of a dynamic riparian ecosystem: The lower Allier River (France)

Riparian ecosystems are highly dynamic and are subject to hydrogeomorphological processes. In Europe, the lower Allier River (France) is one of the last remaining meandering rivers with laterally dynamic sections. For this study, we developed an original method to analyse the vegetation assemblages and succession processes. The analysis includes both spatial and temporal evolution in order to evaluate the shifting paradigm of habitat mosaic at the study site over a 60-year period. On the long-term, floods with low recurrence intervals tend to be important for small scale habitat changes, whereas major flood events lead to major habitat changes. Flood events did not change the overall habitat composition of the active tract but their spatial distribution. The lack of major hydrogeomorphological disturbance observed during the last two decades, however, led to a higher stability of floodplain ecotopes.
The Building Performance Perspective for Interoperability: Requirements for a Future Analysis Network

There is an increasing demand for building performance assessment among architects mostly due to a rising awareness for issues related to environmental sustainability. However, after thirty years of research, interoperability of performance analysis tools with CAAD environments is still far from being seamless. Yet, all commercial CAAD vendors have recently started offering an array of building analysis tools. It is fair to expect a new surge of efforts in integrating prediction and evaluation capabilities within CAAD systems over the next few years. Building on lessons learned, this paper argues the need for a unification infrastructure for building performance and outlines the requirements for building an analysis network.
Erratum: How does expectation affect sensory experience?

Prior expectation affects posterior experience and emotions. This psychological effect is called expectation effect. Two different patterns of expectation effect, contrast and assimilation, were observed. In this talk, I proposed a mathematical model of the expectation effect that explains the conditions of contrast and assimilation[1]. I hypothesized that perceived variable is estimated using a Bayes’ inference of prior prediction and likelihood based on sensory stimuli. I formalized the expectation effect as a function of three factors: expectation error, prediction uncertainty, and external noise. Both the results of the computer simulation using the model and the experiment using Size-weight illusion (SWI) revealed that 1) the pattern of expectation effect shifted from assimilation to contrast as the prediction error increased, 2) uncertainty decreased the extent of the expectation effect, 3) and external noise increased the assimilation. Furthermore, I discussed the meanings of expectation effect from an ecological point of view.

Spatial distribution of the risk for metabolic complications: an application in south-east Brazil, 2006–2007

Abstract Objective To identify spatial variation in the risk for metabolic complications (RMC) by means of a semi-parametric approach for multinomial data. Design Cross-sectional study. Setting We visited 730 households selected in the first of a two-stage sample in South health district in Campinas, São Paulo, Brazil, 2006–2007. Subjects We interviewed 651 individuals and obtained their respective anthropometric measures and geographical coordinates of their house location. They were classified according to a combination of BMI and abdominal circumference as having no risk, increased, high or very high RMC. Results Gender, age and schooling were associated with RMC. Crude spatial risk for the three levels of RMC in relation to the absence of risk suggested different patterns in each level. Adjusted spatial risk for the RMC showed smaller significant areas, but the pattern remained similar to crude risk. Conclusions Spatial point analysis with a multinomial approach improves the understanding of differences in RMC found, as we could identify specific areas in which to intervene. The public health significance of these findings may lie in the additional evidence provided that spatial location and its features can influence patterns of RMC.
Thermodynamic Behavior of Ce Compounds Close to a $T \to 0$ Critical Point

There is a reduced group of Ce very heavy Fermions (VHF) which do not order magnetically down to at least T ≈ 500 mK because they are very close to a T<sub>ord</sub> = 0 critical point. These compounds are at the top of the lim<sub>T→ 0</sub> C<sub>m</sub>/T specific heat values because they collect very high density of low energy excitations. From the analysis of C<sub>m</sub>(T)/T and entropy S<sub>m</sub>(T) dependencies performed on selected CePd<sub>3</sub>M<sub>x</sub> ternaries (where M = B and Be) a quantitative evaluation of an upper limit for the density of excitations can be proposed. These observations exclude any evidence of C<sub>m</sub>(T)/T divergency as T→ 0 in agreement with thermodynamic laws. A comparison with selected Yb-base VHF supports these features.
EVALUATION OF THE COMPRESSIBILITY EFFECTS IN A SPATIALLY DEVELOPING 3 D TURBULENT MIXING LAYER BY USING LARGE EDDY SIMULATION

The present study deals with the Large Eddy Simulation of a plane turbulent compressible mixing layer spatially developing downstream of a at plate. This work focuses on the ability of the L.E. S. to take into account the compressibility e ects and to predict correctly the evolution of the coherent structures in a compressible turbulent free ow. The spatial development of the ow is considered, starting at the trailing edge of the at plate and following both the wake development and the set up of the mixing layer. The L.E. S. is performed by using the ltered Navier-Stokes and total energy equations and a compressible version of the mixed-scale model is employed to take into account the subgrid scale contributions. The resolution of the Navier-Stokes equations has been achieved by means of a conservative nite di erence method based on a 3 order WENO scheme coupled with a Runge-Kutta time integration. Two physical con gurations, similar to the experimental ones studied at the LEA/CEAT of Poitiers, are investigated, corresponding respectively to convective Mach numbers of 0.64 and 1.0. An important attention has been devoted to the treatment of the boundary conditions based on the characteristic method. Good agreements are achieved on the mean and rms values of the velocity pro les in the self-similarity region of the mixing layer. The e ects of compressibility have also been studied. The decrease of the spreading rate of the mixing layer is correctly predicted. Following a kinetic energy balance, these e ects can be attributed to the decrease of the pressure-dilatation terms.
A new methodology for assessment of the susceptibility to data retention in floating gate non-volatile memories

We have developed a new methodology with statistical simulation of leakage current resulting in Vt shift over time of tail bit for assessment of the susceptibility to data retention in floating gate flash memories. The statistical simulation results of Vt distribution are verified with measurements of programmed bit in actual product with good agreement. The new methodology can effectively predict the Vt distribution of programmed bit for determining the data retention failure rate of floating gate non-volatile memories without multi-year bakes and analyzing the leakage mechanism of concern for our process and design.
An updated electromagnetic simulation of the HERA antenna with CST and comparison with measurements

This memo presents an improved model of the HERA antenna as well as the parameters used to simulate its electromagnetic properties. The antenna consists of a faceted parabolic reflector with a diameter of 14 m, a PAPER feed made up of two perpendicular dipoles between two metal plates, and a cylindrical cage above the feed. Based on the work of optimisation performed by David DeBoer , the antenna is thoroughly modelled with CST, and the effects of the different materials are also taken into account. In our simulation, a dipole is excited via a differential termination port with a 100-Ω impedance, by a Gaussian pulse centred on 150 MHz and with a bandwidth of 200 MHz. The transient solver of CST is used to characterise the antenna in the time domain, and in particular the scattering parameters of the antenna are computed between 50 and 250 MHz. Then, these results are compared to the S-parameters measured on a real HERA antenna built in Cambridge (UK) at Lord’s Bridge, by using a 2-port VNA connected to the bars of a dipole via 2 50-Ω coaxial cables. The S-parameters obtained with our simulation and measurements do agree well. Thus, the goal of this document is to clearly describe this model, which can be used to accurately study the properties of the antenna and its effects on the received signal. Lastly, the results of our simulations can be found in the following GitHub repository: https://github.com/Nicolas-Fagnoni/Simulations.
Enriching Augmented Reality Games with CityGML 3 D semantic modeling

3D representations are recognized as an essential component of Augmented Reality (AR) oriented applications. However, not many examples of ARoriented applications employ structured 3D data models despite the existence of standard 3D information models like CityGML. One of the reasons for this shortcoming can be explained by lack of a step by step approach for enriching ARoriented data models with 3D features. Therefore, a three step procedure is proposed to address this limitation such (1) back-ward engineering of an AR-oriented application to its current data model, (2) enriching the current data model with 3D representation factures, (3) a mapping the enriched model to a standard 3D information model. A notable contribution of this work is that the procedure of data modeling has been subject to the UModelAR meta-model which has brought a complementary standpoint to 3D geospatial modeling in the adoption AR environments. Furthermore, the enriched data model has been mapped to CityGML information model with CityGML Application Domain Extension (ADE) concept. To demonstrate the feasibility of this approach, an operating mobile AR-oriented game has been used for the case study.
A modified model for the fading signal at a mobile radio channel

A generalization of an existing model for the fading signal at a mobile radio antenna has been made. The generalization lies in letting the scattering waves not necessarily be traveling horizontally. The effects of this generalization are investigated concerning probability density function (pdf), correlational properties, and power spectra of the phase and envelope. The pdf is not affected, but the power spectrum of the envelope is significantly affected. This generalized spectrum is smoother than the original and always finite, which the latter is not. Thus it is assumed that the generalized model is more consistent with measured spectra, especially in urban environments.
Sulfur ion concentration dependent morphological evolution of CdS thin films and its subsequent effect on photo-electrochemical performance.

The sulfur ion concentration dependent morphological evolution and its subsequent effect on photo-electrochemical properties of chemically synthesized CdS thin films have been systematically investigated. The plausible growth mechanism for the morphological evolution of CdS thin films due to a change in sulfur ion concentration has been proposed. Scanning electron micrographs (SEMs) reveal that the morphology of CdS thin films has been changed from spherical grains to vertically aligned nanoflakes by systematic control of sulfur ion concentration. This article elucidates the astute relationships between precursor concentrations, reaction rate and morphological evolution. The X-ray diffraction (XRD) patterns reveal the formation of hexagonal wurtzite CdS thin films with the preferred (002) orientation for CdS nanoflakes, which is further supported by the analysis of the high resolution transmission electron micrographs (HRTEMs). Optical absorption studies show a red shift in the absorption edge with an increase in sulfur concentration. The beneficial role of nanoflake formation is easily reflected in the photo-electrochemical performance. Improved solar cell performances are observed for CdS nanoflakes grown with a sulfur to cadmium ion concentration ratio of 4 (S : Cd = 4).
Unification Yang–Mills Groups and Representations with CP as a Gauge Symmetry

We investigate more generally the possible unification Yang–Mills groups GYM and representations with CP as a gauge symmetry. Besides the possible Yang–Mills groups E8, E7, SO(2n + 1), SO(4n), SP(2n), G2 or F4 (or a product of them) which only allow self-contragredient representations, we present other unification groups GYM and representations which may allow CP as a gauge symmetry. These include especially SU(N) containing Weyl fermions and their CP conjugates from low energy spectra in a basic irreducible representation (IR). Such an example is the 496-dimensional basic IR (on antisymmetric tensors of rank two) of SU(32) containing SO(32) as a subgroup in the adjoint IR, or SU(248) in a fundamental IR containing E8 as a subgroup in the adjoint IR. Our consideration also leads to the construction of a physical operator (CP) intrinsically as an inner automorphism of order higher than two for the unification group. We have also generalized the possible groups as unification GYM to include nonsemisimple Li.
Medication adherence and adverse effect profile of antiepileptic drugs in Nigerian patients with epilepsy.

AIM Medication adherence remains a major challenge among patients with epilepsy (PWE) with the adverse effect profile of antiepileptic drugs (AEDs) as one of its main drivers. METHODS This was a cross-sectional questionnaire-based study among PWE in selected Nigerian tertiary healthcare facilities using the Morisky Medication Adherence Scale and the Liverpool Adverse Effect Profile (LAEP). RESULTS 126 PWE from four tertiary healthcare facilities were included in this study comprising of 59 (46.8%) males and 67 (53.2%) females. Carbamazepine (104/70.7%), sodium valproate (23/15.6%) and phenytoin (11/7.5%) were the most commonly prescribed AEDs. Using the Morisky Medication Adherence Scale, 17.2, 38.3 and 44.5% of patients were classified as having high, medium and low adherence, respectively. The mean LAEP score was 23.69 ± 6.07. The most common reported adverse effects among respondents were tiredness (30.4%) and headache (22.5%). CONCLUSION Medication adherence to AED was poor among patients in this study.
Ten-year secular trend of overweight and obesity in school children in south-eastern Poland.

OBJECTIVE To examine the trend in prevalence of overweight and obesity in schoolchildren from south-eastern Poland over a 10-year period. MATERIALS AND METHOD A cross-sectional study was conducted in randomly selected primary schools. In total, 4,248 children (2,182 boys and 2,066 girls), mean age 10.5±2.4 years, were examined in 1998, and 2,412 children (1,184 boys and 1,228 girls), mean age 10.5±2.3 years in 2008. In each school the entire population was studied. RESULTS In 2008, the prevalence of overweight in girls was 13.3% and obesity 7.7%, compared to 12.0% and 10.1% in 1998. The decrease in obesity prevalence was statistically significant. In boys, the prevalence of overweight in 2008 was 14.2% and obesity 6.4%, compared to 10.5% and 6.8% in 1998. The increase in overweight prevalence among boys was statistically significant. CONCLUSIONS A trend toward stabilization of the prevalence of overweight and obesity was noted in school children from south-eastern Poland between 1998-2008. The declining prevalence of obesity in girls and increased prevalence of overweight in boys demonstrates that in this age group of children the secular trend is gender dependent.
Director Tenure and Leadership Effectiveness over Internal Controls

The purpose of this paper is to empirically examine the relationship between director tenure and leadership effectiveness as measured by weaknesses in internal control. Using data on over 3,000 U.S. companies for the years 2004-2014, we document a significant and positive relationship between the length of director tenure and corporate governance effectiveness. This result is consistent with the hypothesis that directors gain valuable expertise/experience as their tenure increases. Our results should be useful to management, corporate directors, investors, and other stakeholders that have an interest in the impact of director tenure on the leadership effectiveness of the board of directors.
Rampart-Line Antenna with a Dielectric Superstrate for UHF RFID Applications

A printed Rampart line antenna with a dielectric superstrate for passive Radio Frequency Identification (RFID) tags is presented. A design process is outlined to determine the number of elements used in the Rampart line antenna to achieve the required gain for the desired read range. An inductive loop is then added to the port to match the antenna with the passive tag circuitry. It is shown that a passive tag with a printed Rampart line antenna and a dielectric superstrate can achieve comparable read ranges to commercially available passive RFID tags.
Nifedipine administered in pregnancy: effect on the development of children at 18 months

The safety of use of the calcium channel blocker nifedipine in pregnancy as it affects child development has not been well evaluated. We report the results, with regard to the safety for children of use of nifedipine in pregnancy, on children followed up at 18 months of age born from women recruited in a study comparing routine treatment with nifedipine compared with no treatment 1 .
