Genomic DNA isolation from Artemisia species grown in cold desert high altitude of India

Artemisia which produces a large number of secondary metabolites is naturally found in cold desert high altitude environment of India. Secondary metabolites such as alkaloids, flavonoids, phenols, polysaccharides and terpenes represent a significant barrier to the extraction of pure genomic DNA. Thus, in this study, the DNA extraction protocol to extract pure genomic DNA from different Artemisia species was tailored. The protocol was based on the CTAB method with slight modifications. In the study, 1.6 M NaCl, 2% cetyltrimethyl ammonium bromide (CTAB), 3% polyvinylpyrrolidone (PVP) and 0.5% β-mercaptoethanol was used in the extraction buffer. The incubation period was kept for 1 h at 65°C with one-tenth of the volume of warm (55°C) 10% CTAB solution during the extraction process. This study described a reliable protocol for extracting good quality and optimum amount of DNA from Artemisia species suitable for PCR analysis. Key words : Artemisia, genomic DNA isolation, PCR amplification, secondary metabolites.
Nucleotide excision repair and photoreactivation in sugarcane endophyte Gluconacetobacter diazotrophicus strain PAL 5

Nucleotide excision repair is a DNA repair mechanism mediated by three proteins encoded by the uvrABC gene homologues. This study shows that the mutant B12 of the diazotrophic sugarcane endophyte Gluconacetobacter diazotrophicus, carrying a transposon insertion in a uvrC homologue is hypersensitive to ultraviolet C irradiation. The exposure of irradiated mutant cells to visible light partially reverts the hypersensitivity, indicating that photoreactivation is another DNA repair mechanism active in G. diazotrophicus. Accordingly, a photolyase encoding gene is present on its genome. Therefore, this study brings experimental evidence that nucleotide excision repair and photoreactivation are DNA repair mechanisms in G. diazotrophicus.
Psychiatry in the context of extended emotion: is there a constitutive environmental contribution to panic attacks?

from the bodily states consciously felt when experiencing an emotion, they will see that there is nothing left (Prinz, 2005). To reiterate—take away the elevated heartbeat, sweaty palms and chills from someone who is experiencing fear, and only a state of clear thought will remain, with no symptoms to testify for their agitation. Yet this appeal is not entirely grounded in evidence, even though it does demonstrate why emotions should be caused by bodily change rather than vice versa, because a state of clear thought is attainable in the absence of bodily sensation or despite it, but it is not a default. The most prominent criticisms of the original James-Lange theory are concerned with the strength of the link between bodily sensations and emotion. For example, some observations have asserted that diminished bodily perception does not always include diminished emotions and that some emotions do not involve bodily change. This does not show that the somatic theory of emotions is false, but it indicates that this theory does not generalize. As Griffiths points out when arguing against the establishment of a universal approach: ―the psychological, neuroscientific, and biological theories that best explain any particular subset of human emotions will not adequately explain all human emotions‖ (Griffiths, 2004, p. 233). This allows us to accept that emotions form a mongrel category, and that any explanatory frameworks can make assertions about subsets of this category or aspects of it, but not everything that it comprises. Prinz, however, has suggested that ―the somatic approach can subsume anything that deserves to be called an emotion. ‖ (Prinz, 2004b, p. 49). To him cases of disembodied emotions, such as an art critic‘s alleged exclaim of delight upon seeing some artwork but showing no somatic response, are imitations rather than ̳real‘ emotions. However this assumption indicates that the somatic theory does not in fact answer the fundamental question—what emotions actually are. Given that the range of emotions we can experience is very wide and some of them seem to have more obvious bodily correlates whereas others seem to have none, we yet again arrive at the problem of distinguishing between different 1 Biologically basic emotions, such as Paul Ekman‘s ―Big Six‖; I shall elaborate on that in the last section of this chapter.
Performance Evaluation of the Hot and Warm Stone Mastic Asphalt Mixture

Warm Mix Asphalt is a new type of asphalt mixture which can reduces the mixing temperature and emissions. A kind of warm agent (LRT) is chosen in this study. Hot and warm mix asphalt mixture were designed and their high temperature, low temperature, moisture sensitivity and fatigue pavement performance were evaluated. the tests results is shown that HMA is slightly better in moisture resistance while WMA is slightly better in rutting and cold cracking resistance. About 30oC reduction in mixing temperature can be achieved by using LRT, which resulted in a significant reduction in fuel consumption and exhaust emission.
2 The Parlett-Kahan and Modified Parlett-Kahan Algorithms

In this paper we analyze two subclasses of ABS class of methods which produce orthogonal projection vectors. We theoretically prove that the “twice is enough” selective reorthogonalization criterion of Parlett-Kahan [14] and of Hegedüs [8] can be used in the various ABS classes. Here we also provide a detailed numerical analysis of these ABSbased algorithms. We revealed that the ABS-based algorithm combined with the modified Parlett-Kahan criterion by Hegedüs provided more accurate results in the three considered cases (the rank of the coefficient matrix, the determination of the orthogonal bases, and the QR factorization) than the built-in rank and qr MATLAB functions.
Simulated annealing applied to a file allocation problem

The simulated annealing is applied to an instance of the file allocation problem. The implementation of the algorithm is demonstrated using this example. A study of the effects of using different penalty functions on this problem is performed. The results indicate that the choice of penalty function can have a significant impact on the performance of the algorithm. In particular, I conclude that the effect of a poor choice of penalty function can not be remedied by slower cooling.
Lawrence Berkeley National Laboratory Recent Work Title Accelerating Queries on Very Large Datasets Permalink

In this chapter, we explore ways to answer queries on large multi-dimensional data efficiently. Given a large dataset, a user often wants to access only a relatively small number of the records. Such a selection process is typically performed through an SQL query in a database management system (DBMS). In general, the most effective technique to accelerate the query answering process is indexing. For this reason, our primary emphasis is to review indexing techniques for large datasets. Since much of scientific data is not under the management of DBMS systems, our review includes many indexing techniques outside of DBMS systems as well. Among the known indexing methods, bitmap indexes are particularly well suited for answering such queries on large scientific data. Therefore, more details are given on the state of the art of bitmap indexing techniques. This chapter also briefly touches on some emerging data analysis systems that don’t yet make use of indexes. We present some evidence that these systems could also benefit from the use of indexes.
Techniques d'interaction exploitant la mémoire pour faciliter l'activation de commandes. (Interaction techniques using memory to facilitate command activation)

Pour controler un systeme interactif, un utilisateur doit habituellement selectionner des commandes en parcourant des listes et des menus hierarchiques. Pour les selectionner plus rapidement, il peut effectuer des raccourcis gestuels. Cependant, pour etre efficace, il doit memoriser ces raccourcis, une tâche difficile s’il doit activer un grand nombre de commandes. Nous etudions dans une premiere partie les avantages des gestes positionnels (pointage) et directionnels (Marking menus) pour la memorisation de commandes, ainsi que l’utilisation du corps de l’utilisateur comme surface d’interaction et l’impact de deux types d’aides semantiques (histoires, images) sur l’efficacite a memoriser. Nous montrons que les gestes positionnels permettent d’apprendre plus rapidement et plus facilement, et que suggerer aux utilisateurs de creer des histoires liees aux commandes ameliore considerablement leurs taux de rappel. Dans une deuxieme partie, nous presentons des gestes bi-positionnels qui permettent l’activation d’un grand nombre de commandes. Nous montrons leur efficacite a l’aide de deux contextes d’interaction : le pave tactile d’un ordinateur portable (MarkPad) et une montre intelligente (SCM).
Modeling Bidirectional Reflectance Distribution Function of One-dimensional Random Rough Surfaces with the Finite Difference Time Domain Method

This article describes the development of a suite of programs that is capable of simulating the radiation properties of a random rough surface (RRS). The fundamental approach involves the generation, by fast Fourier transform (FFT) built with rigorous finite difference time domain (FDTD), as the theoretical basis for the simulation of a bidirectional reflectance distribution function (BRDF) of the RRS. The results are compared with the measurements and modeling of existing work to verify the feasibility of customized programming. It was found that the results of this study were a better match to the measurement data than those achieved in other modeling work.
Modélisation multi-agents d'un système de recherche d'information multimédia à forte composante vidéo. (Multiagent modelling of a information retrieval system for images and videos collections)

Les techniques mises en oeuvre pour retrouver et presenter des informations multimedias font appel a des connaissances et des savoir-faire heterogenes: celles du documentaliste, celles des specialistes de chaque media impliquent, celles des specialistes du domaine de l'application, etc.) Dont la plupart evoluent rapidement. Nous nous interessons plus particulierement a la recherche d'information dans des collections de documents video, qui sont complexes et riches en information. L'approche documentaire traditionnelle exploite des descriptions des documents pour effectuer la recherche. Dans le modele de description que nous proposons, les differents aspects de connaissance qui peuvent etre exploites sont modelises par facettes, chaque facette correspondant au point de vue d'un expert sur les documents. Nous avons retenu le formalisme des graphes conceptuels pour representer ces descriptions: plus riches que des descriptions par mots-clefs, les graphes conceptuels permettent de representer des nuances et des concepts complexes. Toutefois, le systeme n'impose pas a l'utilisateur de formuler sa requete dans le formalisme que connait l'application, mais sous la forme d'une liste de mots-clefs, qu'il peut eventuellement ponderer pour indiquer leurs importances relatives. Nous avons concu une societe d'agents qui se met au service de l'utilisateur pour l'aider dans sa recherche d'information: les agents de recherche etablissent leur strategie de maniere dynamique, en fonction de la situation. Ils s'appuient sur les jugements de l'utilisateur a propos des documents proposes non seulement pour ameliorer leur recherche, mais pour evaluer leurs performances. Cette societe d'agents doit etre capable d'evoluer. Definir les agents d'un tel systeme et leur organisation dynamique, etudier les modes d'interactions et de cooperation qui peuvent s'etablir entre eux durant une session de recherche, tel a ete l'objet principal de notre travail. Les idees que nous avons developpees ont ete implantees dans le prototype multi-agents safari-video.
Holonomic modules associated with multivariate normal probabilities of polyhedra

The probability content of a convex polyhedron with a multivariate normal distribution can be regarded as a real analytic function. We give a system of linear partial differential equations with polynomial coefficients for the function and show that the system induces a holonomic module. The rank of the holonomic module is equal to the number of nonempty faces of the convex polyhedron, and we provide an explicit Pfaffian equation (an integrable connection) that is associated with the holonomic module. These are generalizations of results for the Schl\"afli function that were given by Aomoto.
Contributions to the analysis of multicomponent signals: synchrosqueezing and associated methods. (Contributions à l'analyse des signaux multicomposantes: synchrosqueezing et méthodes associées)

Many physical signals including audio (music, speech), medical data (ECG, PCG), marine mammals or gravitational-waves can be accurately modeled as a superposition of amplitude and frequency-modulated waves (AM-FM modes), called multicomponent signals (MCSs). Time-frequency (TF) analysis plays a central role in characterizing such signals and in that framework, numerous methods have been proposed over the last decade. However, these methods suffer from an intrinsic limitation known as the uncertainty principle. In this regard, reassignment method (RM) was developed with the purpose of sharpening TF representations (TFRs) given respectively by the short-time Fourier transform (STFT) or the continuous wavelet transform (CWT). Unfortunately, it did not allow for mode reconstruction, in opposition to its recent variant known as synchrosqueezing transforms (SST). Nevertheless, many critical problems associated with the latter still remain to be addressed such as the weak frequency modulation condition, the mode retrieval of an MCS from its downsampled STFT or the TF signature estimation of irregular and discontinuous signals. This dissertation mainly deals with such problems in order to provide more powerful and accurate invertible TF methods for analyzing MCSs.This dissertation gives six valuable contributions. The first one introduces a second-order extension of wavelet-based SST along with a discussion on its theoretical analysis and practical implementation. The second one puts forward a generalization of existing STFT-based synchrosqueezing techniques known as the high-order STFT-based SST (FSSTn) that enables to better handle a wide range of MCSs. The third one proposes a new technique established on the second-order STFT-based SST (FSST2) and demodulation procedure, called demodulation-FSST2-based technique (DSST2), enabling a better performance of mode reconstruction. The fourth contribution is that of a novel approach allowing for the retrieval of modes of an MCS from its downsampled STFT. The fifth one presents an improved method developed in the reassignment framework, called adaptive contour representation computation (ACRC), for an efficient estimation of TF signatures of a larger class of MCSs. The last contribution is that of a joint analysis of ACRC with non-negative matrix factorization (NMF) to enable an effective denoising of phonocardiogram (PCG) signals.
Novel Approaches to the Clustering of Large Graphs. (Nouvelles approches pour le partitionnement de grands graphes)

Graphs are ubiquitous in many fields of research ranging from sociology to biology. A graph is a very simple mathematical structure that consists of a set of elements, called nodes, connected to each other by edges. It is yet able to represent complex systems such as protein-protein interaction or scientific collaborations. Graph clustering is a central problem in the analysis of graphs whose objective is to identify dense groups of nodes that are sparsely connected to the rest of the graph. These groups of nodes, called clusters, are fundamental to an in-depth understanding of graph structures. There is no universal definition of what a good cluster is, and different approaches might be best suited for different applications. Whereas most of classic methods focus on finding node partitions, i.e. on coloring graph nodes so that each node has one and only one color, more elaborate approaches are often necessary to model the complex structure of real-life graphs and to address sophisticated applications. In particular, in many cases, we must consider that a given node can belong to more than one cluster. Besides, many real-world systems exhibit multi-scale structures and one much seek for hierarchies of clusters rather than flat clusterings. Furthermore, graphs often evolve over time and are too massive to be handled in one batch so that one must be able to process stream of edges. Finally, in many applications, processing entire graphs is irrelevant or expensive, and it can be more appropriate to recover local clusters in the neighborhood of nodes of interest rather than color all graph nodes. In this work, we study alternative approaches and design novel algorithms to tackle these different problems. The novel methods that we propose to address these different problems are mostly inspired by variants of modularity, a classic measure that accesses the quality of a node partition, and by random walks, stochastic processes whose properties are closely related to the graph structure. We provide analyses that give theoretical guarantees for the different proposed techniques, and endeavour to evaluate these algorithms on real-world datasets and use cases.

Dynamic Characterization of Adhesive Materials for Vibration Control

This chapter focuses on the dynamic characterization of adhesive materials for vibration control proposes. First, the experimental characterization and modelization of the relaxation and complex moduli of the flexible adhesive ISR 70-03 by means of a dynamic mechanical thermal analysis technique (DMTA) are presented. Then, the interconversion path between the relaxation modulus EðtÞ and the corresponding complex modulus E ðωÞ for linear viscoelastic solid materials is explored. In contrast to other approximate methods, in this work the fast Fourier transform (FFT) algorithm is directly applied on relaxation functions. Finally, an experimental study for the structural noise and vibration reduction in a cabin elevator by means of adhesive-bonded joints of panels is presented.
Recent radical shifts of atmospheric circulations and rapid changes in Arctic climate system

Arctic climate system change has accelerated tremendously since the beginning of this century, and a strikingly extreme sea‐ice loss occurred in summer 2007. However, the greenhouse‐gas‐emissions forcing has only increased gradually and the driving role in Arctic climate change of the positively‐polarized Arctic/North Atlantic Oscillation (AO/NAO) trend has substantially weakened. Although various contributing factors have been examined, the fundamental physical process, which orchestrates these contributors to drive the acceleration and the latest extreme event, remains unknown. We report on drastic, systematic spatial changes in atmospheric circulations, showing a sudden jump from the conventional tri‐polar AO/NAO to an unprecedented dipolar leading pattern, following accelerated northeastward shifts of the AO/NAO centers of action. These shifts provide an accelerating impetus for the recent rapid Arctic climate system changes, perhaps shedding light on recent arguments about a tipping point of global‐warming‐forced climate change in the Arctic. The radical spatial shift is a precursor to the observed extreme change event, demonstrating skilful information for future prediction.
The cost of uncorrelation and non-cooperation in MIMO channels

We investigate the sum-capacity loss for using uncorrelated Gaussian inputs over multiple-input multiple-output (MIMO) power-constrained linear additive-noise channels in multi-user configurations. We show that the sum-capacity loss is bounded by a universal constant which depends only on the total number of input and output dimensions of the channel, but is independent of the channel matrix, the noise distribution and the number of users. Specifically, for a multiple-access channel with a total number of nt transmit antennas and base-station with nr receive antennas, the sum-capacity loss is at most C* = min{1/2, nr/2nt log2(1 + nt/nr)} bit per input dimension (or 1 bit per transmit antenna per second per Hertz). If we restrict attention to Gaussian noises, then the capacity loss is upper bounded by CG* = min{0.265, 0.265nr/nt log2(nt/nr)}, and this bound is tight for certain channel matrices and noise spectra. We show also that the same bounds hold for the sum-capacity loss of uncorrelated Gaussian input over linear MIMO broadcast channels, input distribution being interpreted either in terms of the equivalent point-to-point channel with Sato condition, or as the output distribution of a "dirty-paper" transmitter. One implication of these results is the limited value of coherence and water-filling in spatial transmission. Another implication is the limited capacity loss in multi-user configurations relative to the fully cooperative (point-to-point) channel
Evaluation of the anxiolytic effect of Echium amoenum petals extract, during chronic treatment in rat

Echium amoenum (Boraginaceae), a very popular medicinal plant in Iran traditional medicine, is used as a tonic, tranquillizer, diaphoretic, cough and sore throat remedy, and antipneumonia. Preliminary phytochemical studies of the plant showed that it contains saponins, flavonoids, unsaturated terpenoids and sterols. In this study, an aqueous extract from petals of this plant was used 125 mg/kg as compared to diazepam 1 mg/kg, i.p., during two different treatment courses, 15 and 30 days. The aqueous extract was prepared by Soxhlet apparatus with distilled water. A sample size of 36 rats in 6 groups was selected for this experiment. Three groups were treated by saline, diazepam and extract daily for 15 days and the other groups for 30 days. Anxiolytic effect of extract was investigated in rat using the elevated plus-maze model of anxiety. After finishing these courses and 30 min after the last injections, the test was performed. The results revealed that in 30-day treatment course, time spent in open arms was significantly higher than that of 15-day treatment in both diazepam and extract groups and this effect was the highest in the diazepam group. So, the results of the study indicated a significant durationdependent increase in time spent in open arms of plus-maze.
