One of the gaps that has to be filled for the fully deployment of web activities is a closer human relationship with the user. This lack can only be dealt with understanding user online actions, which will make proactive and autonomous web behavior possible. In order to find out what navigators behavior looks like it is crucial to understand the semantics underlying their clicks. Being aware of current navigation patterns is not always enough. Knowledge about user objectives and session goals can be discovered from the information collected and tracked by web clicks. Nevertheless, information on these clicks has to be enriched with semantics if user behavior understanding is the ultimate goal. This paper presents an approach that provides an estimation of the end result of a user navigation in terms of site goals achievements. Once clickstream information has been enriched we propose to apply a method based on discriminant analysis in order to obtain two different results: (i) the relevant factors that contribute most to the success of a session and (ii) a statistical classification method to estimate the result of an ongoing session. In order to carry out this proposal, we also present the design of an agent-based architecture in which the role of each agent is deeply analyzed.
Composite backward differentiation formula : an extension of the TR-BDF 2 scheme

This paper presents a class of one-step multi-stage backward differentiation formulas (BDFs), called composite BDFs or C-BDFs, as a generalization of the TR-BDF2 composite scheme. These schemes are equivalent to singly diagonally implicit RungeKutta (SDIRK) methods of special type, and regarded as the one-step analogs of the multi-step Gear’s methods, the so-called backward differentiation formulas (BDFs). Unlike the standard BDFs, however, the C-BDFs do not need external startup calculation while maintaining the full accuracy of the scheme. The C-BDF can be easily implemented as it is made up of the simplest Forward Euler and Backward Euler processes, which are interleaved with interpolation and extrapolation operations on intermediate solutions.
Calculating the Added-Value of Iran's Economy by the Use of 'Input-Output Table' (The Year of 2001)

Developing the input-output tables of Iran's economy is of such a high importance that, formulating and studying the added value in Iran's economy by making use of input-output tables is the most important issue dealt with in this article. In order to more accurately investigate the use of input-output tables of the economy of Iran in the years which they are offered, it has been attempted to calculate the value added in various sectors of the economy using input-output tables in the year 2001 in Iran.
Title Genomic analysis reveals key aspects of prokaryotic symbiosis in the phototrophic consortium ¿ Chlorochromatium aggregatum ¿ Permalink

Background: ‘Chlorochromatium aggregatum’ is a phototrophic consortium, a symbiosis that may represent the highest degree of mutual interdependence between two unrelated bacteria not associated with a eukaryotic host. ‘Chlorochromatium aggregatum’ is a motile, barrel-shaped aggregate formed from a single cell of ‘Candidatus Symbiobacter mobilis”, a polarly flagellated, non-pigmented, heterotrophic bacterium, which is surrounded by approximately 15 epibiont cells of Chlorobium chlorochromatii, a non-motile photolithoautotrophic green sulfur bacterium. Results: We analyzed the complete genome sequences of both organisms to understand the basis for this symbiosis. Chl. chlorochromatii has acquired relatively few symbiosis-specific genes; most acquired genes are predicted to modify the cell wall or function in cell-cell adhesion. In striking contrast, ‘Ca. S. mobilis’ appears to have undergone massive gene loss, is probably no longer capable of independent growth, and thus may only reproduce when consortia divide. A detailed model for the energetic and metabolic bases of the dependency of ‘Ca. S. mobilis’ on Chl. chlorochromatii is described. Conclusions: Genomic analyses suggest that three types of interactions lead to a highly sophisticated relationship between these two organisms. Firstly, extensive metabolic exchange, involving carbon, nitrogen, and sulfur sources as well as vitamins, occurs from the epibiont to the central bacterium. Secondly, ‘Ca. S. mobilis’ can sense and move towards light and sulfide, resources that only directly benefit the epibiont. Thirdly, electron cycling mechanisms, particularly those mediated by quinones and potentially involving shared protonmotive force, could provide an important basis for energy exchange in this and other symbiotic relationships.
A CASE STUDY OF SPONTANEOUS SPEECH IN JAPANESE

This paper investigates spontaneous speech in Japanese, particularly phonetic phenomena that do not normally occur in carefully pronounced formal speech. I discuss several pronunciation variations in a corpus, including reduction or deletion of both vowels and consonants. In this study, I also analyzed a specific speech utterance, which has a combination of some of those pronunciation variations, in detail. It was often difficult to identify each segment in the utterance solely by listening to just the few segments themselves (micro-listening), even if listening to the entire phrase (macrolistening) sounded intelligible. I conducted a perceptual experiment using this utterance; the results showed that the same speech segment was perceived as two morae by micro-listening and as five morae by macro-listening. Listeners use a combination of temporal and contextual cues to reconstruct a speaker’s intentions, although the phenomena found in spontaneous speech show that phonetic segments may change their appearance.
How Innovation Systems and Development Theories complement each other

The paper aims at comparing some of the most influential theories of development with the notion of Innovation Systems (IS). The objective is to understand if this comparison can be used to delve into the role of innovation within the development process. We start defining the main features that characterizes Innovation Systems. Then we contrast it with different branches of development theories: the Sen’s theory of capability building and the Institutionalism, the neo-classic approach and cumulative processes (multiple equilibrium approaches) and finally, the Structures and System Theories (LA structuralism approach, the dependency and world-system theory). We conclude that the interaction between IS and the theories considered represents a mutual benefit. IS, indeed, provide a systemic vision that considers innovation as a holistic process, giving a central role to social and economic factors. Hence, IS might be successfully applied to complement the classic development approach. Innovation Systems could also get benefits from this interaction: development theories shed light on the different ways to think of systemic relationships. Finally, rather than focusing on the discussion of IS being or not a theory for development by itself, we believe that making this relational exercise could generate new benefits and frameworks of analysis for the research community.
Design, analysis, and testing of a microdot apodizer for the apodized pupil Lyot coronagraph (Research Note) II. Impact of the dot size

Context. The Apodized Pupil Lyot Coronagraph (APLC) is a promising coronagraphic device for direct exoplanet detection with the European Extremely Large Telescope. This concept features amplitude apodization in the entrance aperture, and a small opaque Lyot mask in the focal plane. We present new near-IR laboratory results using binary apodizers – the so-called microdot apodizer – which represent a very attractive and advantageous solution for the APLC. Aims. Microdot apodizers introduce high-frequency noise whose characteristics depend on the pixel size. The aim of this work is to characterize the impact of the pixel size on the coronagraphic image. We aim to estimate both the noise intensity and its localization in the field of view. Methods. The microdot apodizer, consisting of an array of pixels with spatially variable density that are either opaque or transparent, was manufactured by lithography of a light-blocking metal layer deposited on a transparent substrate. A set of 5 masks has been designed with different pixel sizes, tested in the near-IR, and their behavior compared to theoretical models. Results. Stray light diffraction introduced by the finite pixel size was measured during experiments. The intensity decreases, and radial distance increases, when the pixel size gets smaller. Conclusions. The physical properties of these microdot apodizers have been demonstrated in the laboratory. The microdot apodizer is a suitable solution for any coronagraph using pupil amplitude apodization, if properly designed.
Sampled-data $H^{\infty}$ Optimization for Self-interference Suppression in Baseband Signal Subspaces

In this article, we propose a design method of selfinterference cancelers for wireless relay stations taking account of the baseband signal subspace. The problem is first formulated as a sampled-data $H^{\infty}$ control problem with a generalized sampler and a generalized hold, which can be reduced to a discretetime $\ell^2$-induced norm minimization problem. Taking account of the implementation of the generalized sampler and hold, we adopt the filter-sampler structure for the generalized sampler, and the uspampler-filter-hold structure for the generalized hold. Under these implementation constraints, we reformulate the problem as a standard discrete-time $H^{\infty}$ control problem by using the discrete-time lifting technique. A simulation result is shown to illustrate the effectiveness of the proposed method.
Cogging torque reduction of Interior Permanent Magnet Synchronous Motor (IPMSM)

In this paper using combination of two separated ideas the torque ripple of Interior Permanent Magnet Synchronous Motor (IPMSM) is reduced. These two ideas are rotor PM segmented and modifying the rotor structure based on pole-arc ratio of flux barrier optimization. In addition the torque ripple due to the reluctance torque component decreased too. Analysis and simulation results including saturation have been performed using analytical method and Finite Element Method (FEM). The rotor flux barrier configuration of the proposed design is carried out by Response Surface Method (RSM) as optimization technique which is verified by FEM
Title Nonlinear transfer in heated L-modes approaching the LH transition threshold in Alcator

Nonlinear transfer processes between large-scale edge flows and the ambient broadband fluctuations have been shown to play a significant role in the dynamics of edge turbulence, including spreading power from coherent modes and suppressing turbulence at the formation of edge transport barriers. In order to predict thresholds of confinement regimes, both the transition dynamics and the parametric dependence of the nonlinear energy transfer must be studied. Since the expected flow damping terms depend on ion collision rates and local safety factor, recent experiments aimed also to explore the nonlinear drive at various values of the plasma current, density and amount of auxiliary heating. Nonlinear interactions between zonal flows and turbulence in L-mode are estimated using bispectral as well as time-resolved methods based on gas-puff-imaging in Alcator C-Mod[1]. PACS numbers: 52.25.

β-Hausdorff Operator on Lipschitz Space in the Unit Polydisk *

In this paper, we define β-Hausdorff operator on the unit polydisk and study the boundedness of the operator on Lipschitz space. Firstly, we translate the problem of coefficient into integral of weighted composition operator, then give the sufficient conditions of boundedness, and also obtain an upper bound for the operator norm on Lipschitz space.
On the possibilities and limits of "DEAF DEAF SAME": Tourism and empowerment camps in Adamorobe (Ghana), Bangalore and Mumbai (India)

This article qualitatively analyzes the ways that the discourse of "deaf universalism" circulates within two common deaf practices: tourism and engaging in interventions. Arguing that the largely Northern-situated discipline of Deaf Studies does not adequately examine how deaf bodies and discourses travel, ethnographic data compiled in India and Ghana during transnational encounters is employed to examine how claims of "sameness" and "difference" are enacted and negotiated. Similarly, this article examines how deaf individuals and groups deploy the concepts of deaf "heavens" and "hells" to analyze their travel experiences and justify interventions. We argue that deaf travelers and those engaging in interventions, mostly from Northern countries, employ teleological concepts that they attempt to impose on deaf "others. " Adopting a critical approach, this article argues for the importance of carving out a space within Deaf Studies for allowing non-Northern concepts to come to the fore. Keywords: Deaf, Development, Universalism, Discourse, India, Ghana
The Speed Submission to DIHARD II: Contributions & Lessons Learned

This paper describes the speaker diarization systems developed for the Second DIHARD Speech Diarization Challenge (DIHARD II) by the Speed team. Besides describing the system, which considerably outperformed the challenge baselines, we also focus on the lessons learned from numerous approaches that we tried for single and multi-channel systems. We present several components of our diarization system, including categorization of domains, speech enhancement, speech activity detection, speaker embeddings, clustering methods, resegmentation, and system fusion. We analyze and discuss the effect of each such component on the overall diarization performance within the realistic settings of the challenge.
Breaking the Cycle of Adversity in Vulnerable Children and Families: A Thirty-Five Year Study of At-Risk Lower Income Families

Family poverty and childhood adversity follow an intergenerational cycle. Children raised under conditions of social and economic disadvantage are likely to raise their own children under similar conditions. To break this cycle, we need to understand why it occurs and why children’s health and development are threatened by disadvantaged conditions of child rearing. We also need to identify protective processes, such as a healthy and supportive parent-child relationship, that may lead to positive health and development under conditions of risk. The longitudinal findings presented in this paper are a summary drawn from the published results of the Concordia Longitudinal Risk Project: an ongoing, three generational, 35-year study of Montreal families from lower income neighborhoods. The original sample comprised over 4,000 school-aged children. Many of these participants are now parents, and their children have been recruited into the study. Among the long-term processes we examine are family violence, fathers’ presence versus absence in the home, and impact of parental mental health problems on children’s health and development. Drawing from an in-depth assessment of parent-child interactions from infancy to preadolescence, we show how family interaction patterns over time can help to achieve positive outcomes for children . Based on statistical modeling techniques and hierarchical regression, we illustrate the ways in which family poverty and adversity during the childhood of one generation lead to conditions of risk for poverty and adversity in the next, via stressful rearing conditions, family violence, mental and physical health problems, and long-term behavioural problems. From the opposite perspective, we identify the environmental, social, educational and behavioural factors that predict positive outcomes for many children, despite disadvantaged conditions. We also highlight the vital role that parents play in this process and how negative intergenerational patterns may be broken by positive parenting, cognitive stimulation, and environmental support across childhood.
Application of calculus equation in solving thermal decomposition kinetics parameters of flame retardant flexible polyurethane foam

Flexible polyurethane foam has been treated with borax, expanded graphite (EG), EG/borax as flame retardant, respectively. The thermal degradation of samples has been studied by thermogravimetry (TG) and differential thermogravimetry (DTG) in air. From the resulting data, kinetic parameters for different stages of thermal degradation are obtained following the method of Broido. For the decomposition of flexible polyurethane foam and flame retardant flexible polyurethane foam, the activation energy is found to increase from 21.8 to 37.6 kJmol -1 , which
Modification of Nano Tourmaline Surface Treatment Agent and Its Performance on Negative Ion Release

In this paper, a kind of wall fabric’s surface treatment agent modified with nonionic surfactant was reported. This surface treatment agent was prepared by using nano tourmaline powder dispersion in water with surfactant as dispersants by sand milling. Under the influence of different dispersants, the negative ions releasing amount of functional wall fabrics, the milling process and the storage stability of nano tourmaline powder dispersion were discussed. The results showed that nano tourmaline powder dispersion achieved the smallest average diameter of 44 nm and had best storage stability that the average diameter maintained below 200 nm in 17 days when the addition amount of dispersant was 20 percent of the tourmaline powders’ weight. What is more, the quantity of negative ion releasing achieved 6500 ion/cm when addition amount of dispersant was 30 percent. This technique could be used to strengthen productivity of nano tourmaline powder dispersion.

Towards a theory of the family firm: approach to an operational definition and a framework for family businesses

Family business research is still a relatively new field of study in which researches are hardly giving their first steps. According to several scholars a “Theory of the Family Firm” is needed to explain the features that make a family business “unique” and different from non-family firms (Chrisman, et al., 2005). This theory of the family firm should start with a definition of the family business, since defining the object of study is a key requirement for progress in any field. However, so far, there is not a generally accepted definition for the family business. It is probably owed to the complexity of each of the two subsystems that overlap in a family business: the family and the business. Therefore, in this work we review the literature in order to make an approach to a single and operational definition of family business. Moreover different theories are provided to lead theoretical perspectives and make progress in the construction of a framework in which empirical research can be properly interpreted for better understanding the features, outcomes and behaviours of the family firms. Thus, the agency theory, the resource and capacities theory and the stewardship theory are analysed in this work. We conclude by discussing directions for future research concerning family business.
Automorphic Galois representations and the inverse Galois problem for certain groups of type 𝐷_{𝑚}

Let $m$ be a positive even integer greater than four and $\ell$ be an odd prime. In this paper, we prove that at least one of the following groups: $\mbox{P}\Omega^\pm_{2m}(\mathbb{F}_{\ell^s})$, $\mbox{PSO}^\pm_{2m}(\mathbb{F}_{\ell^s})$, $\mbox{PO}_{2m}^\pm(\mathbb{F}_{\ell^s})$ or $\mbox{PGO}^\pm_{2m}(\mathbb{F}_{\ell^s})$ is a Galois group of $\mathbb{Q}$ for infinitely many integers $s > 0$. This is achieved by making use of a slight modification of a group theory result of Khare, Larsen and Savin, and previous results of the author on the images of the Galois representations attached to cuspidal automorphic representations of $\mbox{GL}_{2m}(\mathbb{A}_\mathbb{Q})$.
Weak convergence of empirical Wasserstein type distances

We estimate the Wasserstein type distance between two continuous distributions F and G on R such that the set {F = G} is a finite union of intervals, possibly empty or R. The positive cost function ρ is not necessarily symmetric and the sample may come from any joint distribution H on R 2 having marginals F and G with light enough tails with respect to ρ. The rates of weak convergence and the limiting distributions are derived in a wide class of situations including the classical distances W1 and W2. The key new assumption in the case F = G involves the behavior of ρ near 0, which we assume to be regularly varying with index ranging from 1 to 2. Rates are then also regularly varying with powers ranging from 1/2 to 1 also affecting the limiting distribution, in addition to H.
Rapid uncertainty propagation and chance‐constrained path planning for small unmanned aerial vehicles

With the number of small unmanned aircraft systems in the national airspace projected to increase in the next few years, there is growing interest in a traffic management system capable of handling the demands of this aviation sector. It is expected that such a system will involve trajectory prediction, uncertainty propagation, and path planning algorithms. In this work, we use linear covariance propagation in combination with a quadratic programming‐based collision detection algorithm to rapidly validate declared flight plans. Additionally, these algorithms are combined with a dynamic informed RRT∗ algorithm, resulting in a computationally efficient algorithm for chance‐constrained path planning. Detailed numerical examples for both fixed‐wing and quadrotor small unmanned aircraft system models are presented.
Towards Human Centered AutoML

Building models from data is an integral part of the majority of data science workflows. While data scientists are often forced to spend the majority of the time available for a given project on data cleaning and exploratory analysis, the time available to practitioners to build actual models from data is often rather short due to time constraints for a given project. AutoML systems are currently rising in popularity, as they can build powerful models without human oversight. In this position paper, we aim to discuss the impact of the rising popularity of such systems and how a user-centered interface for such systems could look like. More importantly, we also want to point out features that are currently missing in those systems and start to explore better usability of such systems from a data-scientists perspective.
