Bivariate Error Correction FIGARCH and FIAPARCH Models on the Australian All Ordinaries Index and Its SPI Futures.

In this paper we extend the univariate FIGARCH and FIAPARCH models to a bivariate framework. We estimate bivariate error correction FIGARCH and FIAPARCH models between the All Ordinaries Index and its SPI futures using constant correlation and diagonal parameterisations. We therefore employ a flexible estimation approach that captures the long run equilibrium relationship between the two markets, bi-directional return causality, long memory and asymmetries in volatility, and time varying correlations. The results strongly support the use of this approach. Strong bi-directional return causality exists with the index bearing the burden of adjustment to deviations from long run equilibrium. The results also illustrate the importance of allowing for long memory, asymmetries in volatility, and time varying correlations.
Improving information retrieval using Medical Subject Headings Concepts: a test case on rare and chronic diseases.

BACKGROUND As more scientific work is published, it is important to improve access to the biomedical literature. Since 2000, when Medical Subject Headings (MeSH) Concepts were introduced, the MeSH Thesaurus has been concept based. Nevertheless, information retrieval is still performed at the MeSH Descriptor or Supplementary Concept level. OBJECTIVE The study assesses the benefit of using MeSH Concepts for indexing and information retrieval. METHODS Three sets of queries were built for thirty-two rare diseases and twenty-two chronic diseases: (1) using PubMed Automatic Term Mapping (ATM), (2) using Catalog and Index of French-language Health Internet (CISMeF) ATM, and (3) extrapolating the MEDLINE citations that should be indexed with a MeSH Concept. RESULTS Type 3 queries retrieve significantly fewer results than type 1 or type 2 queries (about 18,000 citations versus 200,000 for rare diseases; about 300,000 citations versus 2,000,000 for chronic diseases). CISMeF ATM also provides better precision than PubMed ATM for both disease categories. DISCUSSION Using MeSH Concept indexing instead of ATM is theoretically possible to improve retrieval performance with the current indexing policy. However, using MeSH Concept information retrieval and indexing rules would be a fundamentally better approach. These modifications have already been implemented in the CISMeF search engine.
Labeling unsegmented sequence data with DNN-HMM and its application for speech recognition

Recently, deep neural network (DNN) with hidden Markov model (HMM) has turned out to be a superior sequence learning framework, based on which significant improvements were achieved in many application tasks, such as automatic speech recognition (ASR). However, the training of DNN-HMM requires the pre-segmented training data, which can be generated using Gaussian Mixture Model (GMM) in ASR tasks. Thus, questions are raised by many researchers: can we train the DNN-HMM without GMM seeding, and what does it suggest if the answer is yes? In this research, we come up with the `yes' answer by presenting forward-backward learning algorithm for DNN-HMM framework. Besides, a training procedure is proposed, in which, the training for context independent (CI) DNN-HMM is treated as the pre-training for context dependent (CD) DNN-HMM. To evaluate the contribution of this work, experiments on ASR task with the benchmark corpus TIMIT are performed, and the results demonstrate the effectiveness of this research.
AXES at TRECVID 2012: KIS, INS, and MED

The AXES project participated in the interactive instance search task (INS), the known-item search task (KIS), and the multimedia event detection task (MED) for TRECVid 2012. As in our TRECVid 2011 system, we used nearly identical search systems and user interfaces for both INS and KIS. Our interactive INS and KIS systems focused this year on using classifiers trained at query time with positive examples collected from external search engines. Participants in our KIS experiments were media professionals from the BBC; our INS experiments were carried out by students and researchers at Dublin City University. We performed comparatively well in both experiments. Our best KIS run found 13 of the 25 topics, and our best INS runs outperformed all other submitted runs in terms of P@100. For MED, the system presented was based on a minimal number of low-level descriptors, which we chose to be as large as computationally feasible. These descriptors are aggregated to produce high-dimensional video-level signatures, which are used to train a set of linear classifiers. Our MED system achieved the second-best score of all submitted runs in the main track, and best score in the ad-hoc track, suggesting that a simple system based on state-of-the-art low-level descriptors can give relatively high performance. This paper describes in detail our KIS, INS, and MED systems and the results and findings of our experiments.

Wavelets: approximation and compression--a review

In this paper, we briefly review the connection between subband coding, wavelet approximation and general compression problems. Wavelet or subband coding is successful in compression applications partly because of the good approximation properties of wavelets. First, we revisit some rate-distortion bounds for wavelet approximation of piecewise smooth functions. We contrast these results with rate-distortion bounds achievable using oracle based methods. We indicate that such bounds are achievable in practice using dynamic programming. Finally, we conclude with an outlook on open questions in the area of compression and representations.
Institutional Factors and Corporate Governance

The purpose of this paper is to explain the role of institutions in different corporate governance arrangements. It applies the logic of trade-off amongst the marginal costs of participants in business organizations as a framework for analyzing corporate governance arrangements in different institutions. The paper provides an empirical evidence of the trade-off of costs between the shareholders and employment and explains how corporate governance functions in setting the trade-off in different institutional contexts. The trade-off approach to corporate governance contributes an alternative approach for comparative economics in explaining the variations of corporate governance amongst countries or political regimes.
Automated Classification of Web Sites using Naive Bayesian Algorithm

 Abstract— Subject based web directories like Open Directory Project's (ODP) Directory Mozilla (DMOZ), Yahoo etc., consists of web pages classified into various categories. The proper classification has made these directories popular among the web users. The exponential growth of the web has made it difficult to manage human edited subject based web directories. The World Wide Web (WWW) lacks a comprehensive web site directory. Web site classification using machine learning techniques is therefore an emerging possibility to automatically maintain directory services for the web. Home page of a web site is a distinguished page and it acts as an entry point by providing links to the rest of the web site. The information contained in the title, meta keyword, description and in the labels of the anchor (A HREF) tags along with the other content is a very rich source of features required for classification. Compared to the other pages of the website, webmasters take more care to design the homepage and its content to give it an aesthetic look and at the same time attempt to precisely summarize the organization to which the site belongs. This expression power of the home page of a website can be exploited to identify the nature of the organization. In this paper we attempt to classify web sites based on the content of their home pages using the Naive Bayesian machine learning algorithm.
Atomic Force Microscopy Images Label-Free, Drug Encapsulated Nanoparticles In Vivo and Detects Difference in Tissue Mechanical Properties of Treated and Untreated: A Tip for Nanotoxicology

Overcoming the intractable challenge of imaging of label-free, drug encapsulated nanoparticles in tissues in vivo would directly address associated regulatory concerns over 'nanotoxicology'. Here we demonstrate the utility of Atomic Force Microscopy (AFM) for visualising label-free, drug encapsulated polyester particles of ∼280 nm distributed within tissues following their intravenous or peroral administration to rodents. A surprising phenomenon, in which the tissues' mechanical stiffness was directly measured (also by AFM) and related to the number of embedded nanoparticles, was utilised to generate quantitative data sets for nanoparticles localisation. By coupling the normal determination of a drug's pharmacokinetics/pharmacodynamics with post-sacrifice measurement of nanoparticle localisation and number, we present for the first time an experimental design in which a single in vivo study relates the PK/PD of a nanomedicine to its toxicokinetics.
A Scalable Peer-to-Peer Overlay for Applications with Time Constraints

With the development of Internet, p2p is increasingly receiving attention in research. Recently, a class of p2p applications with time constraints appear. These applications require a short time to locate the resource and(or) a low transit delay between the resource user and the resource holder, such as Skype, MSN. In this paper we propose a scalable p2p overlay for applications with time constraints. Our system provides supports for just two operations for uplayered p2p applications: (1) Given a resource key and the node's IP who holds the resource, it registers the resource information to the associated node in at most two overlay hops; and (2) Given a resource key and a time constraint(0 for no constraint), it returns if possible a path(one or two overlay hops) to the resource holder, and the transit delay of the path is lower than the time constraint. Results from theoretical analysis and simulations show that our system is viable and scalable.
Oncogenic Herpesvirus Utilizes Stress-Induced Cell Cycle Checkpoints for Efficient Lytic Replication

Kaposi’s sarcoma herpesvirus (KSHV) causes Kaposi’s sarcoma and certain lymphoproliferative malignancies. Latent infection is established in the majority of tumor cells, whereas lytic replication is reactivated in a small fraction of cells, which is important for both virus spread and disease progression. A siRNA screen for novel regulators of KSHV reactivation identified the E3 ubiquitin ligase MDM2 as a negative regulator of viral reactivation. Depletion of MDM2, a repressor of p53, favored efficient activation of the viral lytic transcription program and viral reactivation. During lytic replication cells activated a p53 response, accumulated DNA damage and arrested at G2-phase. Depletion of p21, a p53 target gene, restored cell cycle progression and thereby impaired the virus reactivation cascade delaying the onset of virus replication induced cytopathic effect. Herpesviruses are known to reactivate in response to different kinds of stress, and our study now highlights the molecular events in the stressed host cell that KSHV has evolved to utilize to ensure efficient viral lytic replication.
Health ontology system

Most healthcare institutions such as hospitals and clinics store their data in the form of databases of various formats. The Health Ontology System that we have developed provides a means to integrate these data with concepts and semantics in the form of a shared cumulative ontology for enabling machines to interpret them. This involves three major software tools, namely, Ontology Generator, Ontology Distiller and Ontology Accumulator. The Ontology Generator is used to create an ontology from a selected database using metadata provided by its database management system. In a reverse process, the Ontology Distiller enables a subset of data from an ontology to be distilled into a database for further analysis. The Ontology Accumulator integrates some similar types of ontology to be accumulated in the cumulative ontology. This Integrated Health Ontology System will pave the way for integrating existing data with ontologies that will be useful for developing semantic agents for healthcare domain.
An Alternative Approach to Initializing Mutually Referential Objects

Mutual dependencies between objects arise frequently in programs, and programmers must typically resort to manually filling “initialization holes” to help construct the corresponding object graphs, i.e. null values and/or explicitly mutable locations. This report describes a “base-line” proposal for a generalized form of value recursion in an ML-like language called initialization graphs, where value recursion is given the simplistic semantics of a graph of lazy computations whose nodes are sequentially forced, with uses of recursive values checked for initialization-soundness at runtime. We then develop examples using this mechanism to show how problematic the issue of value recursion is for ML-like languages, and in particular how sophisticated reactive objects cannot be defined in the language without using initialization holes, and how this forces ML programmers to break abstraction boundaries. At the same time we show how OO languages rely extensively on null pointers during initialization. We propose that a general, semi-safe mechanism allows value recursion to be used in conjunction with existing sophisicated abstract APIs such GUI libraries, and allows freshly defined APIs to be both abstract and yet not require clients to use explicit initialization holes. We propose that the initialization mechanism permits more programs to be expressed in the mutation-free fragment of ML, though we do not formally prove this result.
Impacts Of Changes In The Brazilianmobile Termination Rates

This paper presents a study of the impacts of changes in the mobile termination rate in Brazil using 2008 as the base year. For this we use an extension of the monopolistic competition model used by Wright et al (2007) allowing for the charge of interconnection fee also from calls originating on mobile networks and differentiated prices for on-net and off-net calls. After calibration of the model parameters and estimation of the price elasticity of demand for mobile services, we conducted a comparative static analysis varying the mobile termination rate. As a result, we provide the optimal mobile termination rates for each regulator’s objective function.
The Extent of Information: Its Relevance for Random Utility Models

This paper examines the effect of the researcher's definition of a recreator's choice set on the parameter and welfare estimates from standard random utility models. Three choice set definitions are compared: choice sets based on all alternatives within the survey, those alternatives within a specified distance from the respondents home, and alternatives familiar to the individual. We show that parameter and welfare estimates are sensitive to the definition of the choice set. Welfare measures of site closures differ in varying ways depending on the familiarity level of the sites in question.
Scheduling Services in a Queuing System with Impatience and Setup Costs

We consider a single-server queue in discrete time, in which customers must be served before some limit sojourn time of geometrical distribution. A customer who is not served before this limit leaves the system: it is impatient. The service of customers, the loss due to impatience and the holding of customers in the queue induce costs. The purpose is to decide when to serve the customers so as to minimize them. We use a Markov decision process with infinite horizon and discounted cost. We establish the structural properties of the stochastic dynamic programming operator and we deduce that the optimal policy is of threshold type. In addition, we are able to compute explicitly the optimal value of this threshold in terms of the parameters of problem.
String concatenation construction for Chebyshev permutation channel codes

We construct codes for the Chebyshev permutation channels whose study was initiated by Langberg et al. (2015). We establish several recursive code constructions and present efficient decoding algorithms for our codes. In particular, our constructions yield a family of binary codes of rate 0.643 when r = 1. The upper bound on the rate in this case is 2/3 and the previous highest rate is 0.609.

Organizational Leadership in India

This research study tries to understand the relevance of four dimensions (viz., support, team-building, goal emphasis and help with work) of Leadership incorporated by Likert (1967) to identify and classify System 1 to 4 by conducting intensive study of six organizations in India. Data, regarding different aspects of Leaders’ actions/practices/behaviors which resulted in employees’ perception, were collected using Likert and Likert (1976) questionnaire. The study came to the following conclusions and findings that in the country like India any leadership is a category of behaviors. A leadership style is a combination of specific practices through which leaders contribute. Not all actions/practices of a leader that are generally considered as positive or with good intentions from the leaders’ point of view or from the academic angles are equally perceived from same angles by employees. The four dimensions (viz., support, team-building, goal emphasis and help with work) of Leadership are perceived differently by employees in India into four new dimensions of practices or actions or category of behaviors (viz., Expressive Environment Facilitator, Non-Bossy, Democratic and Expectancy Pressure by the leader). These four new leadership dimensions are derived using the Principal Component Analysis from the grounds up approach. The organizations need to look at the leadership practices from the perspective of employees’ perceptions. A leader is not only what a leader does but also how those actions are perceived and that must also be taken into consideration. All these four new dimensions are the contribution into the leadership practices and theory.
Localised Topology Correction for Hypertextured Terrains

Terrains for computer graphics have traditionally been modelled with height fields. In the case of procedurally defined terrains, the height field is generated by a displacement map z = f (x,y). Displacement maps, however, do not allow the formation of such terrain features as overhangs, arches or caves. The most flexible approach to model procedural terrain is to consider it as an implicit surface, given by f (x,y,z) = 0. Hypertexturing can be used to add terrain features to an initially smooth implicit surface. The main drawback of modelling terrains as hypertextures is that terrain fragments can easily become disconnected. A topology correction method is presented that is able to remove all topologically disconnected fragments of a hypertextured terrain, leaving only the main surface of the terrain. The method works in the context of a ray casting algorithm for implicit surfaces and for any given terrain point indicates whether it is connected or not. The method is localised because it only needs to examine the terrain inside a neighbourhood of sufficiently small size around the point that is being tested in order to determine its connectivity state. This localised connectivity test allows the modelling of procedural terrains over wide areas such as terrains defined over an infinite horizontal plane. Our method works with terrains that are C 2 continuous and uses Morse theory to find the critical points of the terrain. The method follows the separatrix lines joining the critical points to isolate disconnected fragments.

Von Neumann''s comparison method for random sampling from the normal and other distributions.

The author presents a generalization he worked out in 1950 of von Neumann''s method of generating random samples from the exponential distribution by comparisons of uniform random numbers on (0,1). It is shown how to generate samples from any distribution whose probability density function is piecewise both absolutely continuous and monotonic on ($-\infty$,$\infty$). A special case delivers normal deviates at an average cost of only 4.036 uniform deviates each. This seems more efficient than the Center-Tail method of Dieter and Ahrens, which uses a related, but different, method of generalizing the von Neumann idea to the normal distribution.
