E ective neurons and attractor neural networks in cortical environment

Single-neuron spike dynamics is reconsidered in a situation in which the neural afferent spike input, originating from non-specific spontaneous activity, is very large compared with the input produced by specific (task related) operation of a cortical module. This the authors argue is the situation prevailing in associative cortex. It is shown that the Frolov-Cowan 'point approximation' can be derived systematically in this case, even in the presence of shunting inhibition.The same type of logic is then applied to the cable theory equation for the neuron. Also, here under low ratio of signal to spontaneous activity in the input, the dynamics linearizes, leading to an integrate-and-fire behaviour for the effective neuron. This element sums its synaptic inputs linearly. Its parameters are the resting parameters of the bare neuron, renormalized by the heavy barrage of impinging spontaneous activity. The only remnant of the geometric structure of the dendritic tree is an effective weakening of the postsynapti.
The usefulness of imaging sensors in motion prediction

It is shown that the response of an image-enhanced tracking loop is superior to that attainable from conventional trackers without imaging capability. Because of the non-Gaussian nature of the problem and the nonlinearities in the motion model, it is difficult to make inclusive generalizations about the relative performance. It is evident though that an imager may help to achieve good quiescent performance without a severe tuning penalty. This exchange is difficult to make with conventional algorithms. Two modified linear Gauss Markov procedures are shown to have similar performance, and in this application, increasing the order of the estimator to shape the ersatz Gaussian disturbance is not worth the additional complexity. The image-based architecture provides 40% better quiescent performance with a somewhat less pronounced improvement during a turn. <<ETX>>
Performance Comparisons Among Digital Radio Techniques Subjected to Multipath Fading

A major source of impairment in microwave digital radio is multipath fading, a phenomenon sufficiently prevalent on many paths to frustrate, the attainment of reliability objectives. Performance during multipath fading depends on such system parameters as channel bandwidth and type of modulation, and on details of the receiver processing (e.g., adaptive schemes, synchronization schemes). This paper compares the performance of different digital radio techniques in the presence of multipath fading. The measure used is the expected fraction of time, conditioned on the occurrence of a fading event, that the eye pattern at the receiver detector is closed. This measure is plotted against spectral efficiency (bit rate/channel bandwidth) for various types of modulation (QPSK, offset QPSK, 8-PSK, 16-PSK, 16-QAM, and offset 16-QAM) and for various forms of carrier recovery, timing recovery, transmit/receive filtering, and adaptive equalization. The computations assume a multipath fading frequency response described by a first-order complex polynomial, where the coefficients obey an empirically derived probability law reported previously. The comparisons show clearly the superiority of high-level modulation and the inferiority of offset modulation. The comparisons also demonstrate significant improvements for each of two adaptive equalizers postulated here.

Contribution a la télémetrie optique active pour l'aide aux déplacements des non-voyants

Ce travail traite des aides optroniques aux deplacements des non-voyants. Prealablement a ce travail, deux « detecteurs de passage » ont ete developpes au Laboratoire Aime Cotton le « Tom Pouce » et le « Teletact ». Le « Tom Pouce » est simple d’utilisation mais presente des limitations pour detecter les passages etroits a des distances superieures a trois metres ainsi que pour eviter les poteaux fins. Le « Teletact » permet de gerer l’ensemble des situations mais le nombre d’utilisateurs est limite par l’effort cognitif important que demande son utilisation ainsi que sa fragilite.Le but principal de cette these est d’ameliorer les capteurs ainsi que leur facon de representer l’espace afin d’avoir un dispositif facile d’utilisation detectant tous les passages.Dans un premier temps, l’hypothese que la forme de la zone de protection ideale devrait etre d’aspect cylindrique est emise. La realisation approchee de cette forme a partir de capteurs infrarouges est analysee theoriquement et validee experimentalement. Deux dispositifs le « Tom Pouce II » et le « Minitact » utilisant ce concept ont ete proposes a des non-voyants et ont recu un accueil favorable. Dans un second temps, les capteurs laser telemetriques du « Teletact » ont ete revus afin d’ameliorer leurs performances permettant entre autres une moindre sensibilite aux contraintes mecaniques. Une nouvelle forme d’association des capteurs infrarouges et laser permet de gerer l’ensemble des configurations de passages, y compris en chicane, avec une interface tactile ayant seulement trois niveaux d’alerte correspondant a trois zones de protection (moins de 2 metres de profondeur sur 10 cm de large, entre 2 et 6 metres sur plus de 50 cm de large, plus de 6m de profondeur et 1m de large ) avec un effort cognitif tres reduit par rapport au « Teletact » initial utilisant 32 sons differents. Des outils pour pouvoir analyser objectivement les performances des dispositifs dans des environnements controles ont ete mis au point afin de pouvoir ajuster finement les formes des zones de protection. Un dernier point concerne les possibilites d’identification des obstacles, l’imagerie est exploree mais s’avere immature, actuellement seules les « astuces d’utilisation » des capteurs sont operationnelles.
A HIGH SPEED VLSI ARCHITECTURE FOR DIGITAL SPEECH WATERMARKING WITH COMPRESSION

The need to provide a copy right protection on digital watermarking to multimedia data like speech, image or video is rapidly increasing with an intensification in the application in these areas. Digital watermarking has received a lot of attention in the past few years. A hardware system based solely on DSP processors are fast but may require more area, cost or power if the target application requires a large amount of parallel processing. An FPGA co-processor can provide as many as 550 parallel multiply and accumulate operations on a single device, but FPGAs excel at processing large amounts of data in parallel, as they are not optimized as processors for tasks such as periodic coefficient updates, decision- making control tasks. Combination of both the FPGA and DSP processor delivers an attractive solution for a wide range of applications. A hardware implementation of digital speech watermarking combined with speech compression, encryption on heterogeneous platform is made in this paper. It is observed that the proposed architecture is able to attain high speed while utilizing optimal resources in terms of area.
Lexicographical explorations of neologisms in the digital age : tracking new words online and comparing wiktionary entries with 'traditional' dictionary representations

This thesis explores neologisms in two distinct but related contexts: dictionaries and newspapers. Both present neologisms to the world, the former through information and elucidation of meaning, the latter through exemplification of real-world use and behaviour. The thesis first explores the representation of new words in a range of different dictionary types and formats, comparing entries from collaborative dictionary Wiktionary with those in expert-produced dictionaries, both those categorised here as ‘corpus-based’ and those termed ‘corpus-informed’. The former represent the most current of the expert-produced dictionary models, drawing on corpora for almost all of the data they include in an entry, while the latter draw on a mixture of old-style citations and Reading Programmes for much of their data, although this is supplemented with corpus information in some areas. The purpose of this part of the study was to compare degrees of comprehensiveness between the expert and collaborative dictionaries as demonstrated by the level and quality of detail included in new-word entries and in the dictionaries’ responsiveness to new words. This is done by comparing the number and quality of components that appear in a dictionary entry, both the standardised elements found in all of the dictionary types, such as the ‘headword’ at the top of the entry, to the nonstandardised elements such as Discussion Forums found almost exclusively in Wiktionary. Wiktionary is found to provide more detailed entries on new words than the expert dictionaries, and to be generally more flexible, responding more quickly and effectively to neologisms. This is due in no small part to the way in which every time an entry or discussion is saved, the entire site updates, something which occurs for expert-produced online dictionaries once a quarter at best. The thesis further explores the way in which the same neologisms are used in four UK national newspapers across the course of their neologic life-cycle. In order to do this, a new methodology is devised for the collection of web-based data for context-rich,
Diversidade de borboletas (Lepidoptera) na borda e no interior de um fragmento de mata, no município de Seara – SC

O desenvolvimento de estudos em relacao a biodiversidade vem ganhando destaque em publicacoes cientificas. A Mata Atlântica e um ecossistema bastante complexo, possuindo uma alta biodiversidade ameacada, sendo a principal causa a fragmentacao. A ordem Lepidoptera e consideravelmente suscetivel a fragmentacao de habitats, por tal motivo e considerada um bioindicador. O presente trabalho teve como objetivo identificar a diversidade de especies de Lepidoptera da borda e do interior de um fragmento de Mata Atlântica (Lato sensu), no municipio de Seara, SC. As coletas foram realizadas em seis trilhas, mensalmente, de Dezembro de 2010 a Novembro de 2011, com esforco amostral de 2 horas/rede/trilha, totalizando 144 horas de amostragem. Registrou-se um total de 274 individuos, pertencentes a de 5 familias, 22 generos e 24 especies. Em relacao a diversidade (indice de Shannon-Wiener H’) da borda e do interior, os dados da borda (H’) 2,19 e interior (H’) 2,30, nao apresentaram diferenca significativa entre os dois ambientes. Os valores encontrados para o indice de Shannon-Wiener foram comparados pelo teste “t” de Student, (t= -0,87), utilizando o programa Past. Assim, esses resultados indicam que a area encontra-se em um estado muito fragmentado, devido a extensao da borda e as trilhas do interior da mata formam pequenos fragmentos com grandes extensoes de borda.

As a part of Traditional Chinese Medicine (TCM), acupuncture may be the most evident therapy among all other complementary and alternative medicines (CAMs). This chapter is going to discuss current trends in basic acu‐ puncture research and clinical trials.
Factors Affecting Self-Efficacy of Teachers in International Private Universities in Thailand

The objective of this study was to study factors, namely nationality and faculty, which affected self-efficacy of teachers in international private universities in Thailand. This quantitative research studied in 10 institutions. The population of this study was 3,000. Stratified sampling by faculty was used to select 341 teachers. Analysis included percentage, mean, and two-way ANOVA. The findings indicated that: 1) In general, teachers’ nationality and faculty relatively affected their self-efficacy with a statistical significance of . 01. 2) The analysis of all faculties showed that Thai and Western teachers perceived their self-efficacy at the highest level. 3) When analyzing by each faculty, Filipino and Western teachers in Business Administration had the highest self-efficacy. Thai and Western teachers, in the Humanities and Social Sciences, had the highest self-efficacy. Thai and Filipino teachers in Education had the highest self-efficacy. Outside these faculties, Indian teachers had the highest self-efficacy, in general. Overall, results indicate that nationalities and faculty have affected self-efficacy of teachers at a certain level. Due to the limitations of this study it is recommended to study further, so that more evidences will verify this conclusion.

Segmentation based online performance problem diagnosis

Currently, the performance problems of software systems gets more and more attentions. Among various diagnosis methods based on system traces, principal component analysis (PCA) based methods are widely used due to the high accuracy of the diagnosis results and requiring no specific domain knowledge. However, according to our experiments, we have validated several shortcomings existed in PCA-based methods, including requiring traces with a same call sequence, inefficiency when the traces are long, and missing performance problems. To cope with these issues, we introduce a segmentation based online diagnosis method in this poster.
Détermination des domaines du facteur de transcription GATA4 impliqués dans l'hypertrophie et la survie des cardiomyocytes

Cardiac hypertrophy, which is charaterized by increased cardiomyocytes size, is primarly related to different compensatory physiological mecanisms progressing into different cardiac diseases, such as cardiovascular remodeling and heart failure. Despite the fact that hypertrophy can be beneficial for heart function, actual knowledge conceming intracellular signaling pathways doesn't allow a clear dissociation of molecular mecanisms implicated either in physiological or pathological cardiac hypertrophie responses. The transcription factor GAT A4 is a key regulator of cardiac development and has also been considered essential for cardiac adaptative responsiveness toward stress, throughout hypertrophy and cardiomyocytes survival. Reports from our laboratory helped us to map, in vitro, different functional regions of GAT A4 related to transcriptional upref,'Ulation of hypertrophie genes expression such as ANP, BNP and a-/~-MHC. The gene transfer technique mediated by adenoviral expression vectors has been used to detennine whether functionnal domains of GAT A4 protein are implicated in myocytes hypertrophy and apoptosis. Furthennore, we evaluated PEXI overexpression effect on cardiomyocytes hypertrophy, a novel transcription factor also considered as a GAT A4 co factor. We principally found that GA T A4 N-tenninal transactivation domain is essential for cytoskeletal reorganization. According to our results, MAPK phosphorylation and interaction sites SI 05 and FI08, respectively, seem to participate in hypertrophie response, but are mainly required for cell survival. Moreover, this study suggests that PEXI, whose activity is intimately related to GA TA4, would be a key transcriptional activator of cardiomyocytes hypertrophy and survival. This work identifies and characterizes a novel regulator of cardiac function. Therefore, the advances of this report increase the actual knowledge related to transcriptional mecanisms implicated in genetic reprogramming of cardiac hypertophy and cardiomyocytes survival, which could eventually lead to the development of preventive and/or therapeutic approaches to counteract cardiovascular diseases.

Dicha afirmacion, a su vez, informa sobre el escenario de incerti dumbres y precariedad en la que se encuentra inmersa la vida actual de la poblacion activa.
Single-User Receivers for Partly Known Interference in Multi-User Environments

In multiuser environments such as cellular radio systems, the limited available bandwidth is one of the principal design constraints. For future high subscriber density systems, frequency reuse is one of the fundamental approaches for efficient spectrum utilization in order to meet the increased demands for capacity. The tolerable co-channel interference at the receivers in the system limits the minimum allowable distance among nearby co-channel users. In turn, the system capacity is limited. In order to achieve a high capacity in such multiuser environments, receivers and modulation techniques must be interference resistant. Conventional receivers are designed to operate in thermal noise without cochannel interference. For performance evaluation in cellular systems, the Gaussian interference model is commonly used, i.e. co-channel interference is modeled as additional thermal noise. In this thesis, we study the co-channel interference in the downlink (transmission from base to mobile station) in symmetrical cellular environments. The results demonstrate that the strongest interferer dominates the total received co-channel interference. One approach to improve the performance in multiuser environments is to use receivers designed for interference environments. We address the design and performance issues for interference adaptive receiver techniques that take advantage of our knowledge of the interference properties. We consider receiver design approaches based on the amount of interference information assumed, and we introduce optimized single interferer adaptive receiver schemes. Performance evaluations in the downlink of symmetrical cellular systems show that by using single interferer adaptive receivers, the cell average error probability and the cell outage probability are significantly reduced. Consequently, the system capacity increases as compared to a system with conventional receivers.
ABSORBABLE METAL IN BONE SURGERY: A FURTHER REPORT ON THE USE OF MAGNESIUM ALLOYS

Magnesium alloys, now obtainable on the commercial market, provide a metallic substance which not only fulfils the required characteristics of rigidity and strength for the internal retention of bone fragments but in addition is totally absorbable. The unique behavior of the metal in respect to its absorbability is of sufficient importance to justify the study of the surgical possibilities of such a substance. Its use bears many distinctive features that cannot be compared to those of the more commonly used plates and bone fixing devices made of nonabsorbable metal. Instead, the alloy metal must be individually con- sidered for the advantages and disadvantages which limit its use to cases in which the mechanical requirements will be amply satisfied and the absorption features will be of value. In the former report 1 the effects of magnesiumaluminum alloy screws and pegs were analyzed in twenty fracture and bone graft cases. New methods
Recast IPOG-D Algorithm with Constraint Handling for Combinatorial Testing

Testing is considered as indispensable part in the development process life cycle of any software. Testing is performed to improve the performance, quality and reliability of the software. Designing of relevant test cases plays a major role in deciding the quality of testing. Hence test case designing activity is crucial for the success of testing. Combinatorial strategies are one of those most extensively used methods for generating test cases. These strategies detect failures which are caused by interactions of parameters in the Software under Test(SUT) and by using some sampling mechanisms a covering array test suite is generated. With increase in the number of parameter coverage, the t-way test size sets also increase exponentially which would result in explosion problem. This paper presents a technique to generate minimal test suites in Combinatorial testing(CT). Optimization technique used is Greedy computation strategy for mutation and selection of test cases, used in selecting the locally worst test case for elimination. That is the test case that does not cover maximum number of uncovered interactions from a pool of candidate test cases. Additionally, Branch and bound technique is used for cross over. It is used to branch for the possibilities of number of test cases as cross over inputs. If a particular test case is not possible the bounding happens, else branched for further selection of test cases as input. Experimental results show that Recast Ipog-D generates better/comparable results as compared to the existing algorithm. Additionally, Recast IPOG-D has also contributed to enhance many known Variable Strength Covering array(VSCA) that exist in literature.
