Analysis and Design of Multichannel Systems for Perceptual Sound Field Reconstruction

This paper presents a systematic framework for the analysis and design of circular multichannel surround sound systems. Objective analysis based on the concept of active intensity fields shows that for stable rendition of monochromatic plane waves it is beneficial to render each such wave by no more than two channels. Based on that finding, we propose a methodology for the design of circular microphone arrays, in the same configuration as the corresponding loudspeaker system, which aims to capture inter-channel time and intensity differences that ensure accurate rendition of the auditory perspective. The methodology is applicable to regular and irregular microphone/speaker layouts, and a wide range of microphone array radii, including the special case of coincident arrays which corresponds to intensity-based systems. Several design examples, involving first and higher-order microphones are presented. Results of formal listening tests suggest that the proposed design methodology achieves a performance comparable to prior art in the center of the loudspeaker array and a more graceful degradation away from the center.
Wireless Sensor Network Protocol Implementation by Using Hybrid Technology

A multi hop wireless sensor network is composed of large number of nodes and consecutive link between them. Wireless sensor network normally consist of large number of distributed nodes. In WSN one of the main problems is related to power issue because every node is operated by external battery. To have a large network life time all nodes need to minimize their power consumption. Node is composed of small battery so energy associated with this is very less so replacing or refilling of battery is not possible which is very costly. Hence some technique are applied through which power associated with each node can be conserved. In this paper we proposed design for implementation of wireless sensor network protocol for low power consumption by using power gating signal.
Template Synthesis of Co(II), Ni(II) and Cu(II) Complexes Derived From Oxamide Ligand and the Reactivity of Cu(II) Complex Towards Human Serum Albumin

A new oxamide ligand 2,2'-(oxalydimino)bis(diacetic acid)[C10H11O10N2],[L] has been synthesized by the condensation reaction of Iminodiacetic acid and Diethyloxalate. This ligand [L] was further allowed to interact with triethylene-tetraamine metal complexes [C16H26N6O8M]Cl2 (where M=Co11, Ni11 and Cu11) to yield the new N4 macrocyclic complexes 3, 3', 6, 6' tetraazadodeca 1-1' diimino N N tetraacetic acid M) chloride ([C16H26N6O8Co]Cl2, [C16H26N6O8Ni]Cl2 and [C16H26N6O8Cu]Cl2). These complexes were characterized by elemental analyses, i.r. , n.m. r. , e.p.r, and u.v. -vis spectroscopy. All the complexes show square planar geometry and are ionic in nature. The kinetic studies of the Cu(lI) complex were ascertained spectrophotometrically by observing the absorbance changes in presence of protein Human Serum Albumin (HSA) in phosphate buffer at different pH's at 300C. The absorbance changes were monitored at 278 nm (λmax of HSA) with respect to time and pseudo-first-order rate constants, kobs, were obtained from the slope of the straight line using the least squares regression method. The electrochemical behaviour of the Cu(ll) complex was monitored by cyclic voltammetry in a phosphate buffer. The Ep values-0.730 and-0.560 V respectively, were obtained at the scan rate of 0.1 Vs-1. The interaction of the Cu(II) complex with the HSA was studied at the same scan rate, which reveals weak binding as the E0 values do not shift considerably. The cyclic voltammogram of the Cu(II) complex bound to HSA was recorded at different pH's also (6.5 to 7.4). The pH-rate profile data reveals that the reactions are pH dependent.
Boundary action of the H + 3 model

We find the boundary action for Euclidean AdS2 D-branes in H+3. This action is consistent with the D-branes' symmetries and with the H+3-Liouville relation for disc correlators. It can be used for performing free-field calculations in the H+3 model with boundaries. We explicitly perform the Coulomb-like integrals which appear in the free-field calculation of the bulk one-point function, and find agreement with previously known conformal bootstrap results.
Decision with Uncertainties, Feasibilities, and Utilities: Towards a Unified Algebraic Framework

Several formalisms exist to express and solve decision problems. Each is designed to capture different kinds of knowledge: utilities expressing preferences, uncertainties on the environment, or feasibility constraints on the decisions, with a possible sequential aspect. Despite the fact that every framework relies on specific properties exploited by dedicated algorithms, these formalisms present interesting similarities. In this paper, we show that it is possible to capture these similarities in a generic algebraic framework for sequential decision making with uncertainties, feasibilities, and utilities. This framework subsumes several existing approaches, from constraint satisfaction problems to quantified boolean formulas, Bayesian networks or possibilistic Markov decision processes. We introduce this framework using a toy example, increasingly sophisticated by uncertainties, feasibilities and possible observations. This leads to a formal definition of the framework together with dedicated queries representing usual decision problems. Generic algorithms for solving the considered queries should allow to both factorize existing algorithmic works and allow for cross-fertilization between the subsumed formalisms.

Results of this cross-sectional study revealed that having identified a purpose in life was associated with greater life satisfaction at these three stages of life. However, searching for a purpose was only associated with increased life satisfaction during adolescence and emerging adulthood. Additionally, aspects of hope mediated the relationship between purpose and life satisfaction at all three stages of life. Implications of these results for effectively fostering purpose are discussed. Introduction Researchers in the field of positive psychology have increasingly focused on the role purpose and hope play in human thriving. A growing body of theoretical and empirical literature suggests that having a purpose in life contributes to optimal human development in a variety of ways. For example, theoretical research identifies purpose as a developmental asset (Benson, 2006) and an important component of human flourishing (Seligman, 2002). Empirical research finds that it is associated with greater levels of happiness (French & Joseph, 1999) and resiliency (Benard, 1991). Youth with purpose are psychologically healthier found that coherence, which measures a global feeling about the comprehensibility, manageability, and mean-ingfulness of the world, is associated with physical and psychological health. Similarly, Debats (1998) found that higher purpose scores were significantly negatively correlated with psychological distress. Purpose also appears to play a role in overcoming life's challenges. Victor Frankl (1959) was one of the first psychologists to propose that having a high-level belief system, such as a purpose in life, enabled people to endure life's hardships. With regards to youth,
On Relaxing Contextual Preference Queries

Personalization systems exploit preferences for providing users with only relevant data from the huge volume of information that is currently available. We consider preferences that dependent on context, such as the location of the user. We model context as a set of attributes, each taking values from hierarchical domains. Often, the context of the query may be too specific to match any of the given preferences. In this paper, we consider possible expansions of the query context produced by relaxing one or more of its context attributes. A hierarchical attribute may be relaxed upwards by replacing its value by a more general one, downwards by replacing its value by a set of more specific values or sideways by replacing its value by sibling values in the hierarchy. We present an algorithm based on a prefix-based representation of context for identifying the preferences whose context matches the relaxed context of the query and some initial performance results.
Fine Mapping and Whole-Genome Resequencing Identify the Seed Coat Color Gene in Brassica rapa

A yellow seed coat is a desirable agronomic trait in the seeds of oilseed-type Brassica crops. In this study, we identified a candidate gene for seed coat color in Dahuang, a landrace of Brassica rapa. A previous study of Dahuang mapped the seed coat color gene Brsc1 to a 2.8-Mb interval on chromosome A9 of B. rapa. In the present study, the density of the linkage map for Brsc1 was increased by adding simple sequence repeat (SSR) markers, and the candidate region for Brsc1 was narrowed to 1.04 Mb. In addition, whole-genome resequencing with bulked segregant analysis (BSA) was conducted to identify candidate intervals for Brsc1. A genome-wide comparison of SNP profiles was performed between yellow-seeded and brown-seeded bulk samples. SNP index analyses identified a major candidate interval on chromosome A9 (A09:18,255,838–18,934,000, 678 kb) containing a long overlap with the target region recovered from the fine mapping results. According to gene annotation, Bra028067 (BrTT1) is an important candidate gene for Brsc1 in the overlapping region. Quantitative reverse transcription (qRT)-PCR revealed that BrTT1 mainly functions in the seed. Point mutations and small deletions in BrTT1 were found between yellow- and brown-seeded Dahuang plants. Collectively, the expression and sequence analysis results provide preliminary evidence that BrTT1 is a candidate gene for the seed coat color trait in Dahuang.
ORBITAL EFFECTS IN MANGANITES

In this paper I give a short review of some properties of the colossal magnetoresistance manganites, connected with the orbital degrees of freedom. Ions Mn3+, present in most of these compounds, have double orbital degeneracy and are strong Jahn–Teller ions, causing structural distortions and orbital ordering. Mechanisms leading to such ordering are shortly discussed, and the role of orbital degrees of freedom in different parts of the phase diagram of manganites is described. Special attention is paid to the properties of low-doped systems (doping 0.1≤x≤0.25), to overdoped systems (x>0.5), and to the possibility of a novel type of orbital ordering in optimally doped ferromagnetic metallic manganites.
Wind tunnel testing of a full scale helicopter blade section with an upstream active Gurney flap

Wind tunnel tests were performed on an aerofoil section comparable to that of a full scale helicopter blade section with an upstream active Gurney flap in the framework of the European project CleanSky ITD Green RotorCraft. A modified NACA0012 profile was used, with 23 Kulite pressure transducers embedded in the profile’s surface and with an integrated actuator system for the Gurney flap. The Gurney flap, positioned at 95% of the chord length and with a deployed size of 1.3% of the chord length, extended the full span width of the section. The aerofoil was supported by a mounting system with automated control of the angle of attack. The effect of the Gurney flap is assessed for various deployment strategies. The test campaign carried out was successful. The aerodynamic behaviour can be extracted from the data and contains valuable information for validation of 2D numerical models developed by other partners in the project. The most important improvement of the setup for future use is the stabilisation of the inclinometer readings, which showed a significant amount of noise.
Wolbachia Interferes with Ferritin Expression and Iron Metabolism in Insects

Wolbachia is an intracellular bacterium generally described as being a facultative reproductive parasite. However, Wolbachia is necessary for oogenesis completion in the wasp Asobara tabida. This dependence has evolved recently as a result of interference with apoptosis during oogenesis. Through comparative transcriptomics between symbiotic and aposymbiotic individuals, we observed a differential expression of ferritin, which forms a complex involved in iron storage. Iron is an essential element that is in limited supply in the cell. However, it is also a highly toxic precursor of Reactive Oxygen Species (ROS). Ferritin has also been shown to play a key role in host–pathogen interactions. Measuring ferritin by quantitative RT-PCR, we confirmed that ferritin was upregulated in aposymbiotic compared to symbiotic individuals. Manipulating the iron content in the diet, we showed that iron overload markedly affected wasp development and induced apoptotic processes during oogenesis in A. tabida, suggesting that the regulation of iron homeostasis may also be related to the obligate dependence of the wasp. Finally, we demonstrated that iron metabolism is influenced by the presence of Wolbachia not only in the obligate mutualism with A. tabida, but also in facultative parasitism involving Drosophila simulans and in Aedes aegypti cells. In these latter cases, the expression of Wolbachia bacterioferritin was also increased in the presence of iron, showing that Wolbachia responds to the concentration of iron. Our results indicate that Wolbachia may generally interfere with iron metabolism. The high affinity of Wolbachia for iron might be due to physiological requirement of the bacterium, but it could also be what allows the symbiont to persist in the organism by reducing the labile iron concentration, thus protecting the cell from oxidative stress and apoptosis. These findings also reinforce the idea that pathogenic, parasitic and mutualistic intracellular bacteria all use the same molecular mechanisms to survive and replicate within host cells. By impacting the general physiology of the host, the presence of a symbiont may select for host compensatory mechanisms, which extends the possible consequences of persistent endosymbiont on the evolution of their hosts.
On Integrable Perturbations of Some Nonholonomic Systems 3 2 Integrable potentials on the plane and sphere

Integrable perturbations of the nonholonomic Suslov, Veselova, Chaplygin and Heisenberg problems are discussed in the framework of the classical Bertrand–Darboux method. We study the relations between the Bertrand–Darboux type equations, well studied in the holonomic case, with their nonholonomic counterparts and apply the results to the construction of nonholonomic integrable potentials from the known potentials in the holonomic case.
Detecting Irregularities by Image Contour Based on Fuzzy Neural Network

Visual analysis of human motion in video sequences has attached more and more attention to computer visions in recent years. In order to indicate pedestrian movement in Intelligent Monitoring System, a Euclidean distance based on centroid method is proposed. And then according to the movement of body a set of standard images contour are made. All matrixes which represent human silhouette are normalized using affine transformation, which cuts computational cost. The difference between two matrixes is regard as fuzzy function. Fuzzy neural network is proposed to infer abnormal behavior of the walker. First of all, a four layer fuzzy neural network is presented. And then Fuzzy C-means clustering algorithm is used to calculate the number of hidden layer nodes. Finally the degree of the anomaly is resulted from the fuzzy membership of the two matrixes difference. Fuzzy discriminant can detect irregularities and implements initiative analysis to body behavior. The results show that the new algorithm has better performance.
Tuberculosis and noncommunicable diseases: neglected links and missed opportunities

Globally, the incidence of tuberculosis (TB) is declining very slowly, and the noncommunicable disease (NCD) burden for many countries is steadily increasing. Several NCDs, such as diabetes mellitus, alcohol use disorders and smoking-related conditions, are responsible for a significant proportion of TB cases globally, and in the European region, represent a larger attributable fraction for TB disease than HIV. Concrete steps are needed to address NCDs and their risk factors. We reviewed published studies involving TB and NCDs, and present a review and discussion of how they are linked, the implications for case detection and management, and how prevention efforts may be strengthened by integration of services. These NCDs put patients at increased risk for developing TB and at risk for poor treatment outcomes. However, they also present an opportunity to provide better care through increased case-detection activities, improved clinical management and better access to care for both TB and NCDs. Hastening the global decline in TB incidence may be assisted by strengthening these types of activities.
In-Vivo Gene Signatures of Mycobacterium tuberculosis in C3HeB/FeJ Mice

Despite considerable progress in understanding the pathogenesis of Mycobacterium tuberculosis (Mtb), development of new therapeutics and vaccines against it has proven difficult. This is at least in part due to the use of less than optimal models of in-vivo Mtb infection, which has precluded a study of the physiology of the pathogen in niches where it actually persists. C3HeB/FeJ (Kramnik) mice develop human-like lesions when experimentally infected with Mtb and thus make available, a faithful and highly tractable system to study the physiology of the pathogen in-vivo. We compared the transcriptomics of Mtb and various mutants in the DosR (DevR) regulon derived from Kramnik mouse granulomas to those cultured in-vitro. We recently showed that mutant ΔdosS is attenuated in C3HeB/FeJ mice. Aerosol exposure of mice with the mutant mycobacteria resulted in a substantially different and a relatively weaker transcriptional response (< = 20 genes were induced) for the functional category ‘Information Pathways’ in Mtb:ΔdosR; ‘Lipid Metabolism’ in Mtb:ΔdosT; ‘Virulence, Detoxification, Adaptation’ in both Mtb:ΔdosR and Mtb:ΔdosT; and ‘PE/PPE’ family in all mutant strains compare to wild-type Mtb H37Rv, suggesting that the inability to induce DosR functions to different levels can modulate the interaction of the pathogen with the host. The Mtb genes expressed during growth in C3HeB/FeJ mice appear to reflect adaptation to differential nutrient utilization for survival in mouse lungs. The genes such as glnB, Rv0744c, Rv3281, sdhD/B, mce4A, dctA etc. downregulated in mutant ΔdosS indicate their requirement for bacterial growth and flow of carbon/energy source from host cells. We conclude that genes expressed in Mtb during in-vivo chronic phase of infection in Kramnik mice mainly contribute to growth, cell wall processes, lipid metabolism, and virulence.
AFDD: Automatic Fault Detection Daemon via Event-Tracing

This paper presents AFDD, an automatic fault detection daemon for high availability computing. First we compare two mainstream fault detection mechanisms which are commonly used by multiple hot standby systems and figure out their advantages and disadvantages. Next we combined the existing two prevalent technologies together: (1) RASdaemon real-time fault detection tools, (2) automatic bug report tools in Red Hat. Performance experiments show that AFDD has significant advantages in real-time error handling and is also user friendly.
Visually Induced Analgesia: Seeing the Body Reduces Pain

Given previous reports of strong interactions between vision and somatic senses, we investigated whether vision of the body modulates pain perception. Participants looked into a mirror aligned with their body midline at either the reflection of their own left hand (creating the illusion that they were looking directly at their own right hand) or the reflection of a neutral object. We induced pain using an infrared laser and recorded nociceptive laser-evoked potentials (LEPs). We also collected subjective ratings of pain intensity and unpleasantness. Vision of the body produced clear analgesic effects on both subjective ratings of pain and the N2/P2 complex of LEPs. Similar results were found during direct vision of the hand, without the mirror. Furthermore, these effects were specific to vision of one's own hand and were absent when viewing another person's hand. These results demonstrate a novel analgesic effect of non-informative vision of the body.
Improving signal subspace estimation for blind source separation in the context of spatially correlated noises

We address the issue of orthogonal techniques for blind source separation of periodic signals when the mixtures are corrupted with spatially correlated noises. The noise covariance matrix is assumed to be unknown. This problem is of major interest with experimental signals. We first recall that principal components analysis (PCA), cannot provide a correct estimate of the signal subspace when the noises are spatially correlated or when their power spectral densities are different. We then introduce a new estimator of the non-noisy spectral matrix using delayed blocks. The only assumption is that the noise correlation and cross correlation lengths must be shorter than the source correlation lengths. Simulation results show the efficiency of the new method.
Using pure: variants across the product line lifecycle

The paper describes a demonstration of pure::variants, a commercial tool for variant and variability management for product lines. The demonstration shows how flexible product line (PL) architectures can be built, tested and maintained by using the modeling and integration capabilities provided by pure::variants. With pure::variants being available for a long time, the demonstration (and the paper) combines both basics of pure::variants, known to parts of the audience, and new capabilities, introduced within the last year.
Modeling Exchange Rates with Incomplete Information 1

Recent research has shown that relaxing the assumptions of complete information and common knowledge in exchange rate models can shed light on a wide range of important exchange rate puzzles. In this chapter, we review a number of models we have developed in previous work that relax the strong assumptions on information. We also review some related literature. JEL: F31, F37, F47
