Neural Network based architecture for Fault Detection and Isolation in air data systems

This paper presents the design, development, integration and flight testing of a Fault Detection and Isolation architecture for an air data computer based on Artificial Neural Networks. A lot of Networks have been trained using Knowledge Discovery in Data Base Process in order to identify faults on air data measurements such as airspeed, sideslip angle, and angle of attack. The proposed methodology makes use of a huge number of flight data for training and testing in the Neural Network design. Flight data have been recorded during flight trials carried out using the experimental aircraft of the Italian Aerospace Research Centre. The proposed architecture tested on flight data gathered during an autonomous mission of an Unmanned Aerial Vehicle (UAV) shows good performance in identifying fault occurrences.
Test coverage and post-verification defects: A multiple case study

Test coverage is a promising measure of test effectiveness and development organizations are interested in cost-effective levels of coverage that provide sufficient fault removal with contained testing effort. We have conducted a multiple-case study on two dissimilar industrial software projects to investigate if test coverage reflects test effectiveness and to find the relationship between test effort and the level of test coverage. We find that in both projects the increase in test coverage is associated with decrease in field reported problems when adjusted for the number of prerelease changes. A qualitative investigation revealed several potential explanations, including code complexity, developer experience, the type of functionality, and remote development teams. All these factors were related to the level of coverage and quality, with coverage having an effect even after these adjustments. We also find that the test effort increases exponentially with test coverage, but the reduction in field problems increases linearly with test coverage. This suggests that for most projects the optimal levels of coverage are likely to be well short of 100%.
In pursuit of desktop evolution: User problems and practices with modern desktop systems

This study deals with the problems users encounter in their daily work with computers and the typical practices that they employ. Sixteen daily computer users were interviewed about their habits and problems that they encountered during document classification and retrieval. For both these areas, we provide an overview of identified user practices and a citation-based analysis of the problems users encountered, including those related to the use of the screen real estate (the actual desktop). Two types of problems were identified: (1) Problems that concern the actual use of the system installed on the computer. (2) Problems that arise when people realise that they are using a system that does not allow for the desired work or organizational functions sought. We were able to show that skill continues to be an important factor with respect to the ease of using today's systems. We suggest the following necessary improvements for the evolution of personal information systems: A storage facility that represents the user's view of information; replacing pure technical file metadata with more user-friendly attributes; and introduction of annotations as a new information type.
The Relationship of Docosahexaenoic Acid (DHA) with Learning and Behavior in Healthy Children: A Review

Childhood is a period of brain growth and maturation. The long chain omega-3 fatty acid, docosahexaenoic acid (DHA), is a major lipid in the brain recognized as essential for normal brain function. In animals, low brain DHA results in impaired learning and behavior. In infants, DHA is important for optimal visual and cognitive development. The usual intake of DHA among toddlers and children is low and some studies show improvements in cognition and behavior as the result of supplementation with polyunsaturated fatty acids including DHA. The purpose of this review was to identify and evaluate current knowledge regarding the relationship of DHA with measures of learning and behavior in healthy school-age children. A systematic search of the literature identified 15 relevant publications for review. The search found studies which were diverse in purpose and design and without consistent conclusions regarding the treatment effect of DHA intake or biomarker status on specific cognitive tests. However, studies of brain activity reported benefits of DHA supplementation and over half of the studies reported a favorable role for DHA or long chain omega-3 fatty acids in at least one area of cognition or behavior. Studies also suggested an important role for DHA in school performance.

The rationality problem for fields of invariants under linear algebraic groups (with special regards to the Brauer group)

This is a survey on the ancient question : Let G be a reductive group over an algebraically closed field k and let V be a vector space over k with an almost free linear action of G on V. Let k(V) denote the field of rational functions on V. Is the subfield of G-invariants of k(V) purely transcendental over k ? For G connected, this is still an open question. After a discussion of general matters (various notions of rationality, various notions of quotients, the no-name lemma), we consider several specific groups G. We then discuss the unramified Brauer group of a function field and describe the work of Saltman and of Bogomolov, leading to computations of the unramified Brauer group of fields of G-invariants. The text is a thoroughly revised version of a text distributed at the 9th latino-american school (Santiago de Chile, July 1988), various versions of which had been circulated over the years. ----- Soient k un corps alg'ebriquement clos, V un espace vectoriel sur k et G un groupe r'eductif connexe sur k agissant lin'eairement sur V.

Dengue 1 Diversity and Microevolution, French Polynesia 2001–2006: Connection with Epidemiology and Clinics

Background Dengue fever (DF) is an emerging infectious disease in the tropics and subtropics. Determinants of DF epidemiology and factors involved in severe cases—dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS)—remain imperfectly characterized. Since 2000, serotype 1 (DENV-1) has predominated in the South Pacific. The aim of this study was (i) to determine the origin and (ii) to study the evolutionary relationships of DENV-1 viruses that have circulated in French Polynesia (FP) from the severe 2001 outbreak to the recent 2006 epidemic, and (iii) to analyse the viral intra-host genetic diversity according to clinical presentation. Methodology/Principal Findings Sequences of 181 envelope gene and 12 complete polyproteins of DENV-1 viruses obtained from human sera in FP during the 2001–2006 period were generated. Phylogenetic analysis showed that all DENV-1 FP strains belonged to genotype IV–“South Pacific” and derived from a single introduction event from South-East Asia followed by a 6-year in situ evolution. Although the ratio of nonsynonymous/synonymous substitutions per site indicated strong negative selection, a mutation in the envelope glycoprotein (S222T) appeared in 2002 and was subsequently fixed. It was noted that genetic diversification was very significant during the 2002–2005 period of endemic DENV-1 circulation. For nine DF sera and eight DHF/DSS sera, approximately 40 clones/serum of partial envelope gene were sequenced. Importantly, analysis revealed that the intra-host genetic diversity was significantly lower in severe cases than in classical DF. Conclusions/Significance First, this study showed that DENV-1 epidemiology in FP was different from that described in other South-Pacific islands, characterized by a long sustained viral circulation and the absence of new viral introduction over a 6-year period. Second, a significant part of DENV-1 evolution was observed during the endemic period characterized by the rapid fixation of S222T in the envelope protein that may reflect genetic drift or adaptation to the mosquito vector. Third, for the first time, it is suggested that clinical outcome may be correlated with intra-host genetic diversity.
The role of microRNA deregulation in the pathogenesis of adrenocortical carcinoma

Adrenocortical carcinoma (ACC) is an aggressive tumor showing frequent metastatic spread and poor survival. Although recent genome-wide studies of ACC have contributed to our understanding of the disease, major challenges remain for both diagnostic and prognostic assessments. The aim of this study was to identify specific microRNAs (miRNAs) associated with malignancy and survival of ACC patients. miRNA expression profiles were determined in a series of ACC, adenoma, and normal cortices using microarray. A subset of miRNAs showed distinct expression patterns in the ACC compared with adrenal cortices and adenomas. Among others, miR-483-3p, miR-483-5p, miR-210, and miR-21 were found overexpressed, while miR-195, miR-497, and miR-1974 were underexpressed in ACC. Inhibition of miR-483-3p or miR-483-5p and overexpression of miR-195 or miR-497 reduced cell proliferation in human NCI-H295R ACC cells. In addition, downregulation of miR-483-3p, but not miR-483-5p, and increased expression of miR-195 or miR-497 led to significant induction of cell death. Protein expression of p53 upregulated modulator of apoptosis (PUMA), a potential target of miR-483-3p, was significantly decreased in ACC, and inversely correlated with miR-483-3p expression. In addition, high expression of miR-503, miR-1202, and miR-1275 were found significantly associated with shorter overall survival among patients with ACC (P values: 0.006, 0.005, and 0.042 respectively). In summary, we identified additional miRNAs associated with ACC, elucidated the functional role of four miRNAs in the pathogenesis of ACC cells, demonstrated the potential involvement of the pro-apoptotic factor PUMA (a miR-483-3p target) in adrenocortical tumors, and found novel miRNAs associated with survival in ACC.
Astrocytes as Gatekeepers of GABAB Receptor Function

The long-lasting actions of the inhibitory neurotransmitter GABA result from the activation of metabotropic GABAB receptors. Enhanced GABAB-mediated IPSCs are critical for the generation of generalized thalamocortical seizures. Here, we demonstrate that GABAB-mediated IPSCs recorded in the thalamus are primarily defined by GABA diffusion and activation of distal extrasynaptic receptors potentially up to tens of micrometers from synapses. We also show that this diffusion is differentially regulated by two astrocytic GABA transporters, GAT1 and GAT3, which are localized near and far from synapses, respectively. A biologically constrained model of GABA diffusion and uptake shows how the two GATs differentially modulate amplitude and duration of GABAB IPSCs. Specifically, the perisynaptic expression of GAT1 enables it to regulate GABA levels near synapses and selectively modulate peak IPSC amplitude, which is primarily dependent on perisynaptic receptor occupancy. GAT3 expression, however, is broader and includes distal extrasynaptic regions. As such, GAT3 acts as a gatekeeper to prevent diffusion of GABA away from synapses toward extrasynaptic regions that contain a potentially enormous pool of GABAB receptors. Targeting this gatekeeper function may provide new pharmacotherapeutic opportunities to prevent the excessive GABAB receptor activation that appears necessary for thalamic seizure generation.
PREDICTIVE IMPACTS OF PERCEIVED LEADERSHIP STYLES ON UNION COMMITMENT AMONG FACULTY MEMBERS IN SOUTH-EAST NIGERIA

This study investigated the predictive impacts of perceived leadership styles on union commitment among faculty members in South-East Nigeria. A total of 404 lecturers, drawn through systematic random sampling from government-owned ASUU-affiliated Universities in South-east Nigeria participated in the study. Ages of participants ranged from 35-58 years with a mean age of 42.66 years and Standard Deviation on 4.00. Male participants were 302 representing 74.75% of the study sample. Female participants were 102 representing 25.25% of the total sample size. The study design was cross-sectional with two levels of leadership: consideration leadership style; and initiating structure leadership style. One hypothesis, stating that initiating structure rather than consideration leadership style will be more predictive of union commitment among faculty members was tested using regression analysis. Results of regression analysis showed that initiating structure rather than consideration leadership style significantly predicted union commitment among faculty members:R 2 = 0.38; F = 371.15, p < 0.001; 95 % (1.14, 1.53) for initiating structure leadership and F = 371.15, p < 0.08; 95 % (-.43, .028) for consideration leadership. This result confirmed the study hypothesis. Implications and study limitations were highlighted.
QED in Finite Volume and Finite Size Scaling Effect on Electromagnetic Properties of Hadrons

On account of the computation of the virtual photon corrections to the hadronic properties by means of lattice QCD simulation, we study the finite size scaling effect on the QED correction using low energy effective theory of QCD with QED. For this purpose, we begin with formulating a new QED on the space with finite volume. By adapting this formalism to the partially quenched QCD with electromagnetism, we compute the finite size scaling effect on the electromagnetic correction to the masses of pseudo-Nambu-Goldstone bosons and observe qualitative features.
Complete spontaneous improvement of non-displaced femoral neck fracture without any surgery modality

Summary Background: Fracture of the femoral neck is still a medical dilemma due to high rates of complications and the choice of treatment. Although rigid internal fixation with cannulated screws through open or percutaneous approaches is the traditional treatment for undisplaced fractures (Garden type I and II) to avoid secondary displacement, considerable controversy still exists regarding the rate of this problem, thus it seems that a new trend in conservative management of this types of femoral neck fracture is emerging. Case Report: Our case is a 46-year-old woman with Garden type II femoral neck fracture, who refused all surgical options and willingly ignored her problem. Six months later she returned to our center with uneventful recovery of her fracture. Conclusions: The previous belief about the absolute poor prognosis of Garden type II with 100% rate of secondary displacement with non-operative management must have been an overestimation or the success histories in the literature about non-operative treatment of these fractures originates from inherited weakness of the Garden classification in differentiating type I from type II. The patient gave the informed consent prior being included into the study.
Surface ultraviolet irradiance from OMI

The Ozone Monitoring Instrument (OMI) onboard the NASA Earth Observing System (EOS) Aura spacecraft is a nadir-viewing spectrometer that measures solar reflected and backscattered light in a selected range of the ultraviolet and visible spectrum. The instrument has a 2600-km-wide viewing swath, and it is capable of daily, global contiguous mapping. We developed and implemented a surface ultraviolet (UV) irradiance algorithm for OMI that produces noontime surface spectral UV irradiance estimates at four wavelengths (305, 310, 324, and 380 nm). Additionally, noontime erythemal dose rate and the erythemal daily dose are estimated. The OMI surface UV algorithm inherits from the surface UV algorithm developed by NASA Goddard Space Flight Center for the Total Ozone Mapping Spectrometer (TOMS). The OMI surface UV irradiance products are produced and archived in HDF5-EOS format by Finnish Meteorological Institute. The accuracy of the surface UV estimates depend on UV wavelength and atmospheric and other geolocation specific conditions ranging from 7% to 30%. A postprocessing aerosol correction can be applied at sites with additional ground-based measurements of the aerosol absorption optical thickness. The current OMI surface UV product validation plan is presented.
Uncertainties and Risks in the Implementation of an E-Learning Information Systems Project in a Higher-Learning Environment: Viewpoints from Estonia

This paper investigates the sorts of risks and uncertainties inherent in implementing an e-learning information systems project in Estonia. The study uses a variation of the Delphi study in eliciting the risk factors or items from experienced top management professionals within the organisation. The main objective of the study is to identify the uncertainties or risks in the implementation of the systems, using the viewpoint of Estonia, which is an emerging economy. The findings of the work indicate that wrong development strategy, staff volatility, change in top management and lack of funding are amongst the top risk factors in implementing e-learning in Estonia. On the other hand, risks emanating from users' involvement and commitment seem to be viewed as less critical to the success of the project.
Combat stance in judo – Laterality differences between and within competition levels

This study examined the impact of lateral preferences (i.e. left-dominant vs. right-dominant fighting stance) on success at different levels of judo competition (German University Championships vs. German Championships vs. Olympic Games). The lateralization of the fighting stance of 840 male judoka (Olympic Games n = 204, German Championships n = 203, & German University Championships n = 433) were compared. First, a comparison of high ranked versus a normative sample was conducted. Second, statistical analyses examined the relative impact of a left-dominant vs. right-dominant fighting stance between and within competition levels. Left dominant judoka from all tournaments ranked 1st-5th were over-represented compared to athletes who ranked 7th or worse at the German University Championship. Lateral differences in fighting stance also differentiated the tournament levels, with the highest percentage of judoka fighting with a left-dominant stance at the Olympic Games. Surprisingly, there were more left dominant judoka at the German University Championship in comparison to the more competitive German Championships. No interaction between fighting stance and rankings was revealed. Lateral differences have performance implications in competitive judo; the impact of a left-dominant fighting stance on competitive success differs within and between competition levels.
Tonal complexity features for style classification of classical music

We propose a set of novel audio features for classifying the style of classical music. The features rely on statistical measures based on a chroma feature representation of the audio data and describe the tonal complexity of the music, independently from the orchestration or timbre of the music. To analyze this property, we use a dataset containing piano and orchestral music from four general historical periods including Baroque, Classical, Romantic, and Modern. By applying dimensionality reduction techniques, we derive visualizations that demonstrate the discriminative power of the features with regard to the music styles. In classification experiments, we evaluate the features' performance using an SVM classifier. We investigate the influence of artist filtering with respect to the individual composers on the classification performance. In all experiments, we compare the results to the performance of standard features. We show that the introduced features capture meaningful properties of musical style and are robust to timbral variations.
Elliptical Galaxy Dynamics

,(a b)/a with a and b the major- and minor-axis lengths. Hubble understood that the observed ellipticity was only a lower limit to the true elongation because of the unknown orientation of a galaxy’s “polar axis”; he called this uncertainty “serious, but unavoidable. ” Nevertheless, he was able to compute an estimate of the frequency function of intrinsic shapes by assuming that elliptical galaxies were oblate spheroids with random orientations (Hubble 1926). Hubble’s remarks remain nearly as valid today as they were six decades ago. Classification of elliptical galaxies is still based almost entirely on their luminosity distributions, and although Hubble’s analysis of the intrinsic shape distribution has been considerably refined, we still know little of a definite nature about the three-dimensional shapes of these systems. An important shift in our understanding of elliptical galaxies took place in 1975, following the discovery that most ellipticals rotate significantly more slowly than expected for a fluid body with the same flattening (Bertola & Capaccioli 1975). Elliptical galaxies were revealed to be “hot” stellar systems, in which most of the support against gravitational collapse comes from essentially random motions rather than from ordered rotation. Two questions immediately arose from these observations: what produces the observed flattenings, and, given that rotation plays only a minor role, are elliptical galaxies axisymmetric or fully triaxial? Binney (1978) suggested that the flattenings were due in large part to anisotropic velocity distributions and noted that triaxial figures were no less likely than axisymmetric ones. His suggestion was quickly followed up by Schwarzschild (1979, 1982), who showed that self-consistent triaxial models could be constructed by the superposition of time-averaged orbits. The phenomenon of triaxiality has since remained cen
