Wavelet transform based phase extraction for interferometer signal analysis

Phase or its associated derivative of signal carries very important information, particularly in the application of interferometry technique in non contact measurement, where measurand such as displacement, strain, velocity etc are encoded in the phase of a fringe signal. In most of the dynamic applications this interferometric signal becomes non stationary in nature. Fourier transform is not suitable for extracting the phase of a non stationary signal. Joint time frequency analysis tool such as STFT (Short Time Fourier Transform) may be applied but it has limitation of fixed resolution. On the other hand CWT (Continuous Wavelet Transform) is suitable as it uses adaptive time window which overcomes the fixed resolution problem in STFT. Present work reports the development of two different phase extraction algorithm namely phase estimation and frequency estimation technique based on CWT. Finally these algorithms are validated with simulated signal as well as experimental data and relative merits of these two approaches are discussed and results are presented.
A Quantitative Analysis and Performance Study for Similarity-Search Methods in High-Dimensional Spaces

For similarity search in high-dimensional vector spaces (or ‘HDVSs’), researchers have proposed a number of new methods (or adaptations of existing methods) based, in the main, on data-space partitioning. However, the performance of these methods generally degrades as dimensionality increases. Although this phenomenon-known as the ‘dimensional curse’-is well known, little or no quantitative a.nalysis of the phenomenon is available. In this paper, we provide a detailed analysis of partitioning and clustering techniques for similarity search in HDVSs. We show formally that these methods exhibit linear complexity at high dimensionality, and that existing methods are outperformed on average by a simple sequential scan if the number of dimensions exceeds around 10. Consequently, we come up with an alternative organization based on approximations to make the unavoidable sequential scan as fast as possible. We describe a simple vector approximation scheme, called VA-file, and report on an experimental evaluation of this and of two tree-based index methods (an R*-tree and an X-tree).
Grammar for ellipsis resolution in Japanese.

This paper elucidates the linguistic mechanisms for resolving ellipsis (zero anaphor). The mechanisms consist of three tiers of linguistic system. [1] Japanese sentences are structured in such a way to anchor the topic, which is predominantly the subject (by Sentence devices), [2] with argument inferring cues on the verbal predicate (by Predicate devices), and [3] are cohesively sequenced with the topic as a pivot (by Discourse devices). This topicalised subject is most prone to ellipsis. This agrees with the fact that over 90% of ellipsis is of topicalised subjects. An interplay of these mechanisms constitute the keys to ellipsis resolution. I have developed an algorithm capturing the mechanisms. The initial hand-simulated test based on a set of narrative texts has shown that the algorithm achieves a high level of accuracy, over 85%.
Complexity of Coupled Human and Natural Systems

Integrated studies of coupled human and natural systems reveal new and complex patterns and processes not evident when studied by social or natural scientists separately. Synthesis of six case studies from around the world shows that couplings between human and natural systems vary across space, time, and organizational units. They also exhibit nonlinear dynamics with thresholds, reciprocal feedback loops, time lags, resilience, heterogeneity, and surprises. Furthermore, past couplings have legacy effects on present conditions and future possibilities.

The configuration of multi-static forward scattering radar enabling the improvement of target detection efficiency is proposed. The forward scattering radar cross section of the widely spread unmanned aerial vehicles is calculated. The required power of the airborne transmitter is estimated.
Dyadisches Coping und Partnerschaftszufriedenheit bei verschiedenen Liebesstilen

Zusammenfassung In den letzten vierzig Jahren wurden viele Versuche unternommen, sich der Komplexitat des Forschungsgegenstandes „Liebe“ anzunahern. Lee entwickelte 1973 ein Klassifikationssystem und unterschied sechs Liebesstile: Eros (die romantische Liebe), Ludus (die spielerische Liebe), Storge (die freundschaftliche Liebe), Mania (die besitzergreifende Liebe), Pragma (die pragmatische Liebe) und Agape (die altruistische Liebe). In dieser Studie wurde der Zusammenhang zwischen Liebesstilen und der gemeinsamen Stressbewaltigung analysiert. 154 Paare wurden zu ihrer Partnerschaft befragt. Die Resultate zeigten, dass Eros am starksten mit dem dyadischen Coping assoziiert ist und pradiktiv sowohl fur das positive als auch fur das negative dyadische Coping ist. Bei den Mannern erwies sich zudem Agape pradiktiv fur das positive dyadische Coping und Pragma als Pradiktor fur das negative dyadische Coping, wahrend sich einzig bei den Frauen Ludus pradiktiv fur das negative dyadische Coping und Pragma pradiktiv fur das positive dyadische Coping erwies. Implikationen fur die Beratung, Paartherapie und zukunftige Forschung werden diskutiert. Schlagworte: Partnerschaft, dyadisches Coping, Liebesstile, Partnerschaftszufriedenheit ----- Abstract In the last forty years, many attempts were made to approach the complexity of “love” as a research topic. In 1973, Lee developed a typology of six different love styles: Eros (passionate love), Ludus (game-playing love), Storge (friendship love), Pragma (logical, “shopping list” love), Mania (possessive, dependent love) and Agape (all-giving, selfless love). The present study examines the association between love styles and dyadic coping. 154 couples were assessed on a variety of relationship measures. Our findings indicated that Eros is most strongly associated with dyadic coping and predictive both for the positive and for the negative dyadic coping. For men Agape turned out to be predictive for the positive dyadic coping and Pragma appeared as a predictor for the negative dyadic coping. Only for women, Ludus proved to be predictive for negative dyadic coping and Pragma turned out to be predictive for positive dyadic coping. Implications for counselling, couple therapy and future research are being discussed.

A Review Selection Approach for Accurate Feature Rating Estimation

In this paper, we propose a review selection approach towards accurate estimation of feature ratings for services on participatory websites where users write textual reviews for these services. Our approach selects reviews that comprehensively talk about a feature of a service by using information distance of the reviews on the feature. The rating estimation of the feature for these selected reviews using machine learning techniques provides more accurate results than that for other reviews. The average of these estimated feature ratings also better represents an accurate overall rating for the feature of the service, which provides useful feedback for other users to choose their satisfactory services.
The impact of misaligned business communication on the quality of salesperson - buyer relationships

Despite the important role of communication in the business-to-business sphere, little attention is given to it in publications. Research conducted so far focused on the level and scope of information exchange or marketing in general. However, an explanation to what degree communication, particularly taking into account buyer needs in communication, has an effect on buyer-salesperson relationships is absent. Therefore, this paper is based on the thesis that salesperson communication, at variance with buyer expectations, leads to deterioration of buyer's trust, satisfaction, commitment and willingness to recommend the salesperson. The paper defines elements of communication indispensable in maintaining relationships with specific parameters (trust, satisfaction, commitment and recommendation). It also indicates that the extent to which not adapting communication has an effect on the buyer-salesperson relationship does not depend on trust which buyers have in salespersons, compared to other sources of information. The effect of the paper is to indicate the areas of communication towards which a salesperson should direct their efforts and such areas, which, even if lacking conformity, do not have a negative effect on buyer-salesperson relationships.

Ultrastructural localization of G‐proteins and the channel protein TRP2 to microvilli of rat vomeronasal receptor cells

Microvilli of vomeronasal organ (VNO) sensory epithelium receptor cells project into the VNO lumen. This lumen is continuous with the outside environment. Therefore, the microvilli are believed to be the subcellular sites of VNO receptor cells that interact with incoming VNO‐targeted odors, including pheromones. Candidate molecules, which are implicated in VNO signaling cascades, are shown to be present in VNO receptor cells. However, ultrastructural evidence that such molecules are localized within the microvilli is sparse. The present study provides firm evidence that immunoreactivity for several candidate VNO signaling molecules, notably the G‐protein subunits Giα2 and Goα, and the transient receptor potential channel 2 (TRP2), is localized prominently and selectively in VNO receptor cell microvilli. Although Giα2 and Goα are localized separately in the microvilli of two cell types that are otherwise indistinguishable in their apical and microvillar morphology, the microvilli of both cell types are TRP2(+). VNO topographical distinctions were also apparent. Centrally within the VNO sensory epithelium, the numbers of receptor cells with Giα2(+) and Goα(+) microvilli were equal. However, near the sensory/non‐sensory border, cells with Giα2(+) microvilli predominated. Scattered ciliated cells in this transition zone resembled neither VNO nor main olfactory organ (MO) receptor cells and may represent the same ciliated cells as those found in the non‐sensory part of the VNO. Thus, this study shows that, analogous to the cilia of MO receptor cells, microvilli of VNO receptor cells are enriched selectively in proteins involved putatively in signal transduction. This provides important support for the role of these molecules in VNO signaling. J. Comp. Neurol. 438:468–489, 2001. © 2001 Wiley‐Liss, Inc.
Speaker adaptation using the i-vector technique for bottleneck features

Deep Neural Networks (DNN) have been largely used and successfully applied in the context of speaker independent Automatic Speech Recognition (ASR). However, these models are not easily adapted to model a specific speaker characteristic. Recently, one approach was proposed to address this issue, which consists of using the I-vector representation as input to the DNN. The I-vector is playing the role of providing information about the speaker as well as the environmental conditions for a given recording. This approach achieved a significant improvement in the context of a hybrid system of DNN combined with Hidden Markov Model (HMM). In this paper, we study the effect of speaker adaptation based on the I-vector framework in the context of stacked bottleneck features. These features, extracted from a second level of DNNs, are modelled by a classical Gaussian Mixture Model (GMM) ASR system. The proposed approach achieved an absolute WER improvement of 1.2% on an Arabic Broadcast news task. Index Terms: DNN, I-Vector, Bottleneck Features, Speech Recognition
The Effect of Teen Childbearing and Single Parenthood on Childhood Disabilities and Progress in School

be responsible for poor health and low levels of schooling among the children of young mothers. This paper uses special disability and grade repetition questions from the school enrollment supplement to the 1992 Current Population Survey to estimate the effect of maternal age and single parenthood on children's disability status and school progress. Our results suggest that there is little association between maternal age at birth and children's disabilities. But the children of teen mothers are much more likely to repeat one or more grades than other children, and within-household estimates of this relationship are even larger than OLS estimates. The grade repetition findings from the CPS are replicated using a smaller sample from the National Longitudinal Survey of Youth. Another finding of interest is that having a father in the household is associated with lower disability prevalence and fewer grade repetitions. But many of the effects of single parenthood on disability, as well as the effect on grade repetition, appear to be explained by higher incomes in two-parent families.
Synergistic and Independent Actions of Multiple Terminal Nucleotidyl Transferases in the 3’ Tailing of Small RNAs in Arabidopsis

All types of small RNAs in plants, piwi-interacting RNAs (piRNAs) in animals and a subset of siRNAs in Drosophila and C. elegans are subject to HEN1 mediated 3’ terminal 2’-O-methylation. This modification plays a pivotal role in protecting small RNAs from 3’ uridylation, trimming and degradation. In Arabidopsis, HESO1 is a major enzyme that uridylates small RNAs to trigger their degradation. However, U-tail is still present in null hen1 heso1 mutants, suggesting the existence of (an) enzymatic activities redundant with HESO1. Here, we report that UTP: RNA uridylyltransferase (URT1) is a functional paralog of HESO1. URT1 interacts with AGO1 and plays a predominant role in miRNA uridylation when HESO1 is absent. Uridylation of miRNA is globally abolished in a hen1 heso1 urt1 triple mutant, accompanied by an extensive increase of 3’-to-5’ trimming. In contrast, disruption of URT1 appears not to affect the heterochromatic siRNA uridylation. This indicates the involvement of additional nucleotidyl transferases in the siRNA pathway. Analysis of miRNA tailings in the hen1 heso1 urt1 triple mutant also reveals the existence of previously unknown enzymatic activities that can add non-uridine nucleotides. Importantly, we show HESO1 may also act redundantly with URT1 in miRNA uridylation when HEN1 is fully competent. Taken together, our data not only reveal a synergistic action of HESO1 and URT1 in the 3’ uridylation of miRNAs, but also independent activities of multiple terminal nucleotidyl transferases in the 3’ tailing of small RNAs and an antagonistic relationship between uridylation and trimming. Our results may provide further insight into the mechanisms of small RNA 3’ end modification and stability control.
Emotion Regulation Difficulties in Boys with Oppositional Defiant Disorder/Conduct Disorder and the Relation with Comorbid Autism Traits and Attention Deficit Traits

Previous research has pointed towards a link between emotion dysregulation and aggressive behavior in children. Emotion regulation difficulties are not specific for children with persistent aggression problems, i.e. oppositional defiant disorder or conduct disorder (ODD/CD), children with other psychiatric conditions, such as autism spectrum disorders or attention-deficit/hyperactivity disorder, have emotion regulation difficulties too. On a behavioral level some overlap exists between these disorders and comorbidity is high. The aim of this study was therefore twofold: 1) to examine emotion regulation difficulties in 65 boys with ODD/CD in comparison to a non-clinical control group (NC) of 38 boys (8–12 years) using a performance measure (Ultimatum Game), parent report and self-report, and 2) to establish to what extent emotion regulation in the ODD/CD group was correlated with severity of autism and/or attention deficit traits. Results on the Ultimatum Game showed that the ODD/CD group rejected more ambiguous offers than the NC group, which is seen as an indication of poor emotion regulation. Parents also reported that the ODD/CD group experienced more emotion regulation problems in daily life than the NC group. In contrast to these cognitive and behavioral measures, self-reports did not reveal any difference, indicating that boys with ODD/CD do not perceive themselves as having impairments in regulating their emotions. Emotional decision making within the ODD/CD group was not related to variation in autism or attention deficit traits. These results support the idea that emotion dysregulation is an important problem within ODD/CD, yet boys with ODD/CD have reduced awareness of this.
The ripple effect: Citation chain reactions of a nobel prize

This paper explores the possible citation chain reactions of a Nobel Prize using the mathematician Robert J. Aumann as a case example. The results show that the award of the Nobel Prize in 2005 affected not only the citations to his work, but also affected the citations to the references in his scientific oeuvre. The results indicate that the spillover effect is almost as powerful as the effect itself. We are consequently able to document a ripple effect in which the awarding of the Nobel Prize ignites a citation chain reaction to Aumann's scientific ouvre and to the references in its nearest citation network. The effect is discussed using innovation decision process theory as a point of departure to identify the factors that created a bandwagon effect leading to the reported observations.
Compress-and-conquer for optimal multicore computing

We propose a programming paradigm called compress-and-conquer (CC) that leads to optimal performance on multicore platforms. Given a multicore system of p cores and a problem of size n, the problem is first reduced to p smaller problems, each of which can be solved independently of the others (the compression phase). From the solutions to the p problems, a compressed version of the same problem of size O(p) is deduced and solved (the global phase). The solution to the original problem is then derived from the solution to the compressed problem together with the solutions of the smaller problems (the expansion phase). The CC paradigm reduces the complexity of multicore programming by allowing the best-known sequential algorithm for a problem to be used in each of the three phases. In this paper we apply the CC paradigm to a range of problems including scan, nested scan, difference equations, banded linear systems, and linear tridiagonal systems. The performance of CC programs is analyzed, and their optimality and linear speedup are proven. Characteristics of the problem space subject to CC are formally examined, and we show that its computational power subsumes that of scan, nested scan, and mapReduce. The CC paradigm has been implemented in Haskell as a modular, higher-order function, whose constituent functions can be shared by seemingly unrelated problems. This function is compiled into low-level Haskell threads that run on a multicore machine, and performance benchmarks confirm the theoretical analysis.
PRICING WITHOUT PRIORS BY DIRK BERGEMANN

We consider the problem of pricing a single object when the seller has only minimal information about the true valuation of the buyer. Specifically, the seller only knows the support of the possible valuations and has no further distributional information. The seller is solving this choice problem under uncertainty by minimizing her regret. The pricing policy hedges against uncertainty by randomizing over a range of prices. The support of the pricing policy is bounded away from zero. Buyers with low valuations cannot generate substantial regret and are priced out of the market. We generalize the pricing policy without priors to encompass many buyers and many qualities.
A Delphi exercise and cluster analysis to aid in the development of potential classification criteria for systemic sclerosis using SSc experts and databases.

OBJECTIVES Since the 1980 ACR classification criteria for systemic sclerosis (SSc) do not identify 20% with SSc, revised criteria are necessary. METHODS Suggested new criteria from the literature were sent in random order to 96 SSc experts. A 3-round Delphi Consensus eliminated criteria. Then cluster analysis reduced items. The Canadian Scleroderma Research Group (CSRG) database was used to determine the prevalence of each item. RESULTS Seventy-one of 96 (71%) completed all 3 rounds; 47 items were expanded to 76 in round 2. Thirty items had at least 50% consensus and 18 had >75% agreement to include (a priori cut point). Clustering occurred for 4 categories: proximal to MCP skin involvement, vascular abnormalities, autoantibodies and tissue damage. Proximal to MCPs skin involvement identified 80% of patients. Adding one item from each of the other 3 categories or 1 or more items from 2 of 3 remaining categories increased the proportion of patients classified to 94% in CSRG patients. Categories included (1) Vascular (dilated capillaries, telangiectasia, Raynaud's phenomenon [RP]), (2) Autoantibodies (anticentromere [ACA] or antitopoisomeraseI [Topo1]) and (3) Fibrosis/damage (esophogeal dysmotility dysphagia, sclerodactyly, digital ulcers). In the CSRG, 98% were identified if using proximal skin involvement; or sclerodactyly plus one of: RP, ACA or Topo1. CONCLUSIONS This is a first step toward developing new SSc classification criteria. A Delphi exercise alone cannot suffice for item reduction. Also, validation prospectively in SSc patients and diseases that mimic SSc is needed in order to calculate sensitivity and specificity of future criteria.
Enhancement of the Efficacy of Chemotherapy for Lung Cancer by Simultaneous Suppression of Multidrug Resistance and Antiapoptotic Cellular Defense

The efficacy of chemotherapy of lung cancer is limited by the development of resistance in cancer cells during treatment. In most lung cancers, this resistance is associated with the overexpression of (a) multidrug resistance-associated protein (MRP) responsible for drug efflux from the cancer cells (pump resistance) and (b) BCL2 protein that activates antiapoptotic cellular defense (nonpump resistance). A novel liposomal proapoptotic anticancer drug delivery system was developed to enhance anticancer efficacy of the well-established drug doxorubicin (DOX). This multicomponent drug delivery system was tested on multidrug-sensitive and -resistant human small-cell lung cancer cells. The drug delivery system includes four components: (a) liposome as a carrier, (b) DOX as an inductor of apoptosis, (c) antisense oligonucleotides (ASOs) targeted to MRP1 mRNA as a suppressor of pump resistance, and (d) ASOs targeted to BCL2 mRNA as a suppressor of nonpump resistance. Intracellular internalization of ASOs and DOX; the influence of the proposed system on the expression of genes and proteins involved in the multidrug resistance, cytotoxicity, and apoptosis induction and antiapoptotic defense; and the activity of caspases were studied. It was found that the proposed liposomal delivery system successfully delivered ASOs and DOX to cell nuclei, inhibited MRP1 and BCL2 protein synthesis, and substantially increased the anticancer action of DOX by stimulating the caspase-dependent pathway of apoptosis in multidrug-resistant human lung cancer cells.
