Efficient MV prediction for zonal search in video transcoding

This paper proposes a method to efficiently find motion vector predictions for zonal search motion re-estimation in fast video transcoders. The motion information extracted from the incoming video stream is processed to generate accurate motion vector predictions for transcoding with reduced complexity. Our results demonstrate that motion vector predictions computed by the proposed method outperform those generated by the highly efficient EPZS (Enhanced Predictive Zonal Search) algorithm in H.264/AVC transcoders. The computational complexity is reduced up to 59.6% at negligible cost in R-D performance. The proposed method can be useful in multimedia systems and applications using any type of transcoder, such as transrating and/or spatial resolution downsizing.
Noninvasive Assessment of the Complexity and Stationarity of the Atrial Wavefront Patterns During Atrial Fibrillation

A novel automated approach to quantitatively evaluate the degree of spatio-temporal organization in the atrial activity (AA) during atrial fibrillation (AF) from surface recordings, obtained from body surface potential maps (BSPM), is presented. AA organization is assessed by measuring the reflection of the spatial complexity and temporal stationarity of the wavefront patterns propagating inside the atria on the surface ECG, by means of principal component analysis (PCA). Complexity and stationarity are quantified through novel parameters describing the structure of the mixing matrices derived by the PCA of the different AA segments across the BSPM recording. A significant inverse correlation between complexity and stationarity is highlighted by this analysis. The discriminatory power of the parameters in identifying different groups in the set of patients under study is also analyzed. The obtained results present analogies with earlier invasive studies in terms of number of significant components necessary to describe 95% of the variance in the AA (four for more organized AF, and eight for more disorganized AF). These findings suggest that automated analysis of AF organization exploiting spatial diversity in surface recordings is indeed possible, potentially leading to an improvement in clinical decision making and AF treatment.
Aberrant Monoaminergic System in Thyroid Hormone Receptor-β Deficient Mice as a Model of Attention-Deficit/Hyperactivity Disorder

Background: Thyroid hormone receptors are divided into 2 functional types: TRα and TRβ. Thyroid hormone receptors play pivotal roles in the developing brain, and disruption of thyroid hormone receptors can produce permanent behavioral abnormality in animal models and humans. Methods: Here we examined behavioralchanges, regional monoamine metabolism, and expression of epigenetic modulatory proteins, including acetylated histone H3 and histone deacetylase, in the developing brain of TRα-disrupted (TRα0/0) and TRβ-deficient (TRβ−/−) mice. Tissue concentrations of dopamine, serotonin (5-hydroxytryptamine) and their metabolites in the mesocorticolimbic pathway were measured. Results: TRβ−/− mice, a model of attention-deficit/hyperactivity disorder, showed significantly high exploratory activity and reduced habituation, whereas TRα0/0 mice showed normal exploratory activity. The biochemical profiles of dopamine and 5-hydroxytryptamine showed significantly low dopamine metabolic rates in the caudate putamen and nucleus accumbens and overall low 5-hydroxytryptamine metabolic rates in TRβ−/− mice, but not in TRα0/0 mice. Furthermore, the expression of acetylated histone H3 was low in the dorsal raphe of TRβ−/− mice, and histone deacetylase 2/3 proteins were widely increased in the mesolimbic system. Conclusions: These findings suggest that TRβ deficiency causes dysfunction of the monoaminergic system, accompanied by epigenetic disruption during the brain maturation process.
Effects of information accuracy and volume on decision making

ABSTRACT Recent advances in information technology have resulted in increasingly complex work environments. Much of the complexity is due to a deluge of information available across networks (Gleick, 2011) and unknown reliability, which introduces additional uncertainty (Platt & Huettel, 2008). Understanding the performance characteristics of human information processing for optimal decision making under such conditions of data abundance and uncertainty is critical in complex networked information environments, such as military operations. One focus of the United States military is providing troops with the richness of information formally reserved for higher echelons (Bawden & Robinson, 2009). However, this effort risks cognitive overload, where too much information can result in impaired performance. The present study examined human decision making under varying levels of cognitive load and source reliability. Participants determined the reliability of two information sources and decided how to use them to minimize cognitive load and improve performance in a visual search task. Unbeknownst to participants, one source provided highly accurate information and one provided moderately accurate information. Results showed that participants had more trust in the more accurate than the less accurate source, and decision making accuracy decreased as cognitive load increased. When cognitive load was highest, participants were more accurate on trials with the more accurate source. Thus, the more accurate source facilitated better performance, whether through better intel or through participants offloading some of the cognitive load to the reliable source.
Efficient Annotation with the Jena ANnotation Environment (JANE)

With ever-increasing demands on the diversity of annotations of language data, the need arises to reduce the amount of efforts involved in generating such value-added language resources. We introduce here the Jena ANnotation Environment (Jane), a platform that supports the complete annotation life-cycle and allows for 'focused' annotation based on active learning. The focus we provide yields significant savings in annotation efforts by presenting only informative items to the annotator. We report on our experience with this approach through simulated and real-world annotations in the domain of immunogenetics for NE annotations.

Optimal PID controller design based on Particle Swarm Optimization for bacterial growth bioprocess

Particle Swarm Optimization represents a heuristic approach that can be used to solve difficult optimization problems. With some relative few modifications this method can be applied to a specific problem. In this work an optimal PID control algorithm for a bacterial growth bioprocess associated with enzymatic catalysis is designed and analyzed. The controller parameters are calibrated using particle swarm optimization algorithms by the minimization of an objective function. The controller tuning problem is approached as a multi-modal numerical optimization problem. Numerical simulations are included to validate the designed controllers. Two nonlinear kinetic expressions - the Monod and Haldane equations - frequently used to define microbial growth, are tested in the model simulations.

In a co-space environment, the physical space and the virtual space co-exist, and interact simultaneously. While the physical space is virtually enhanced with information, the virtual space is continuously refreshed with real-time, real-world information. To allow users to process and manipulate information seamlessly between the real and digital spaces, novel technologies must be developed. These include smart interfaces, new augmented realities, efficient storage and data management and dissemination techniques. In this paper, we first discuss some promising co-space applications. These applications offer experiences and opportunities that neither of the spaces can realize on its own. We then argue that the database community has much to offer to this field. Finally, we present several challenges that we, as a community, can contribute towards managing the co-space.
Origin of the late veneer inferred from Ru isotope systematics

Elevated abundances of the highly siderophile elements (HSE) in the Earth’s mantle are commonly explained by the addition of a chondritic late veneer after cessation of core formation [1]. Although relative HSE abundances and Os isotope compositions of samples derived from the Earth's mantle are similar to those of chondrites [e.g. 2-4], the source and type of the late accreted material has proven difficult to identify. We show that different types of chondrites and iron meteorites all exhibit a deficit in s-process Ru isotopes relative to the Earth's mantle, demonstrating that the late veneer cannot derive from known meteorite sources. Moreover, the meteorites show correlated Mo and Ru isotope anomalies consistent with coupled deficits in s-process Mo and Ru nuclides. This cosmic Mo-Ru correlation [5] passes through the terrestrial composition, indicating that the late veneer derives from the same type of material as the bulk Earth. This is difficult to reconcile with models in which the late accreted material is derived from exotic sources located at greater heliocentric distances, as has been suggested in some recent dynamical models of terrestrial planet formation [6].
‘Sociability before individuality’: lesson structure in lower secondary classrooms

ABSTRACT This paper contributes to the research field of classroom research by offering an empirical analysis of classroom instruction on the level of lesson structure. The research questions are: What are the typical combinations of instructional activities in the lessons of eight teachers in four Norwegian Secondary schools? And how can the content-treatment of these structures be explained considering relevant pedagogical traditions? The method of the study is qualitative non-participatory observation in four Norwegian Secondary schools, with a total dataset of 79 lessons. We found that the most typical combination of instructional activities in the data was the plenary conversation-seatwork-structure. When the content-treatment was analyzed, an ‘expository-practice’-structure was revealed. This lesson structure is explained by the influence of progressive-constructivist pedagogical theories in Scandinavia, foremost Bildung-centred general didactics and Vygotsky-inspired socio-cultural theory. From the perspective of the hidden curriculum, we call this discourse ‘sociability before individuality’.
Towards a theory for integration of mathematical verification and empirical testing

From the viewpoint of a project manager who is responsible for the verification and validation (V&V) of a software system, mathematical verification techniques provide a potentially valuable addition to otherwise standard empirical testing. However, the value they add, both in terms of coverage and in fault detection, has been difficult to quantify. Potential cost savings from replacing testing with mathematical techniques cannot be realized until the tradeoffs can be quantified. This paper first describes a framework for a theory of software fault detection that is based on software reliability and formalized fault models. The novelty of this approach is that it takes into account the relative utility of the various tools for fault detection. Second, the paper describes a utility model for integrating mathematical and empirical techniques with respect to fault detection and coverage analysis for software. Third, the paper discusses how to determine the optimal combination of black-box testing, white-box (structural) testing and formal methods in V&V of a software system. Finally, a demonstration of how this utility model can be used in practice is offered using a case study from a NASA software system.
Media Violence and Children CHAPTER 7 A COMPLETE GUIDE FOR PARENTS AND PROFESSIONALS

London 2003 Video games have become one of the dominant entertainment media for children in a very short time. In the mid-1980s, children averaged about four hours a week playing video games, including time spent playing at home and in arcades (Harris & 'Williams, 1985). By the early 1990s, home video game use had increased and arcade play had decreased. The average amount was still fairly low, averaging about two hours of home play per week for girls, and about four hours of home play per week for boys (Funk, 1993). By the mid 1990s, home use had increased for fourth grade girls to 4.5 hours per week, and to 7.1 hours per week for fourth grade boys (Buchman & Funk, TIME SPENT WITH VIDEO GAMES In 1972, a new form of entertainment became commercially available with the release of the video game Pong. In Pong, two players tried to "hit" an electronic "ball" back and forth. From these humble beginnings, a revolution in the entertainment industry was born. Interactive game revenues are now significantly greater than the domestic film industry ("Industrial Strengths," 2000). Worldwide video games sales are now at $20 billion annually (Cohen, 2000). The PlayStation video game console, which began as a side project at Sony, now represents $6 billion of the company's $20 billion in annual sales (Cohen, 2000). It is reasonable to question whether video games may have similar effects to the effects of other entertainment media. In this chapter the term video game will be used to describe games played on video game consoles (e.g., PlayStation), on computers, or on hand-held video game devices (e.g., GameBoy). Douglas A. Gentile and Craig A. Anderson Violent Video Games: The
Diagnostic accuracy of GPs when using an early-intervention decision support system: a high-fidelity simulation

Background Observational and experimental studies of the diagnostic task have demonstrated the importance of the first hypotheses that come to mind for accurate diagnosis. A prototype decision support system (DSS) designed to support GPs’ first impressions has been integrated with a commercial electronic health record (EHR) system. Aim To evaluate the prototype DSS in a high-fidelity simulation. Design and setting Within-participant design: 34 GPs consulted with six standardised patients (actors) using their usual EHR. On a different day, GPs used the EHR with the integrated DSS to consult with six other patients, matched for difficulty and counterbalanced. Method Entering the reason for encounter triggered the DSS, which provided a patient-specific list of potential diagnoses, and supported coding of symptoms during the consultation. At each consultation, GPs recorded their diagnosis and management. At the end, they completed a usability questionnaire. The actors completed a satisfaction questionnaire after each consultation. Results There was an 8–9% absolute improvement in diagnostic accuracy when the DSS was used. This improvement was significant (odds ratio [OR] 1.41, 95% confidence interval [CI] = 1.13 to 1.77, P<0.01). There was no associated increase of investigations ordered or consultation length. GPs coded significantly more data when using the DSS (mean 12.35 with the DSS versus 1.64 without), and were generally satisfied with its usability. Patient satisfaction ratings were the same for consultations with and without the DSS. Conclusion The DSS prototype was successfully employed in simulated consultations of high fidelity, with no measurable influences on patient satisfaction. The substantially increased data coding can operate as motivation for future DSS adoption.
Auction Theory: A Guide to the Literature

This paper provides an elementary, non-technical, survey of auction theory, by introducing and describing some of the critical papers in the subject. (The most important of these are reproduced in a companion book, The Economic Theory of Auctions, Paul Klemperer (ed.), Edward Elgar (pub.), forthcoming. ) We begin with the most fundamental concepts, and then introduce the basic analysis of optimal auctions, the revenue equivalence theorem, and marginal revenues. Subsequent sections address risk-aversion, affiliation, asymmetries, entry, collusion, multi-unit auctions, double auctions, royalties, incentive contracts, and other topics. Appendices contain technical details, some simple worked examples, and bibliographies.
Macromolecular connections of active zone material to docked synaptic vesicles and presynaptic membrane at neuromuscular junctions of mouse

Electron tomography was used to view macromolecules composing active zone material (AZM) in axon terminals at mouse neuromuscular junctions. Connections of the macromolecules to each other, to calcium channels in the presynaptic membrane, and to synaptic vesicles docked on the membrane prior to fusing with it during synaptic transmission were similar to those of AZM macromolecules at frog neuromuscular junctions previously examined by electron tomography and support the hypothesis that AZM regulates vesicle docking and fusion. A species difference in the arrangement of AZM relative to docked vesicles may help account for a greater vesicle‐presynaptic membrane contact area during docking and a greater probability of fusion during synaptic transmission in mouse. Certain AZM macromolecules in mouse were connected to synaptic vesicles contacting the presynaptic membrane at sites where fusion does not occur. These secondary docked vesicles had a different relationship to the membrane and AZM macromolecules than primary docked vesicles, consistent with their having a different AZM‐regulated behavior. J.

Gesture Recognition and Prediction for Smart Photo Album

This is a project to develop a photo album application using HCI features helping users to view and edit their photos on the easier way. This consists of a 3D photo album and a gesture recognition engine. It aims to solve a major problem of interaction with the same applications which were their dependence on using devices physically and touch them directly. The other point is to have a smart engine that can predict user's next action by studying his previous interaction with this system in order to make such dialogue faster and easier. The contribution includes a natural interaction in digital space.
Money, Credit, and Digital Payment 1971/2014: From the Credit Card to Apple Pay

The article intertwines the history of the American credit card, its standardization, and interactional realization with the latest developments in payment systems. Understanding both credit cards and systems like Apple Pay or blockchain-based applications as part of an administrative longue durée, it argues for a different understanding of the Internet of Things. It should be understood both as a technical-informational and as an accounting infrastructure, with tensions arising between both segments.
