High risk for obstructive sleep apnea in patients with acute myocardial infarction1

Objectives: to stratify the risk for obstructive sleep apnea in patients with acute myocardial infarction, treated at a public, tertiary, teaching hospital of the state of São Paulo, Brazil, and to identify related sociodemographic and clinical factors. Method: cross-sectional analytical study with 113 patients (mean age 59.57 years, 70.8% male). A specific questionnaire was used for the sociodemographic and clinical characterization and the Berlin Questionnaire for the stratification of the risk of obstructive sleep apnea syndrome. Results: the prevalence of high risk was 60.2% and the outcome of clinical worsening during hospitalization was more frequent among these patients. The factors related to high risk were body mass index over 30 kg/m2, arterial hypertension and waist circumference indicative of cardiovascular risk, while older age (60 years and over) constituted a protective factor. Conclusion: considering the high prevalence of obstructive sleep apnea and its relation to clinical worsening, it is suggested that nurses should monitor, in their clinical practice, people at high risk for this syndrome, guiding control measures of modifiable factors and aiming to prevent the associated complications, including worsening of cardiovascular diseases.
User Mobility Pattern Scheme for Location Update and Paging in Wireless Systems

The user mobility pattern (UMP) scheme is introduced for location update and paging in wireless systems where mobile terminals (MTs) maintain their history data in a database called user mobility history (UMH). During a location update, a UMP is derived from UMH and registered to the network. Unless the MT detects that it has moved out of the registered UMP, it does not perform any other location update. On the other hand, cells are paged selectively according to the cell entry times in the registered UMP upon a call arrival for the MT. The related data structures and the protocols for the UMP scheme are presented in the paper. The experimental results show that the UMP scheme outperforms the time-based and movement-based location update schemes as well as the blanket, selective, and velocity paging schemes.
A hybrid 3D modelling approach considering of Java 3D and PTViewer open source

As the world we are living in is three or more dimensions, we have to reconstruct the world in three dimension (3D). However, the world is composed of various things which have different modes, states and attributes. In certain applications, the emphases are put on certain special objects, it is unpractical and unnecessary to describe and express them in a way. Therefore we just need to construct the interesting objects in true 3D reconstruction. The surrounding things can be expressed by other way. So, the paper puts forward that adopting Java 3D to express the interesting objects and adopting panoramic images to be their environments, and the relationships of each panoramic scene are expressed in the 2D map. So, this hybrid approach mainly contains two techniques, the one is how to show the interesting by Java 3D, the other one is the stitching of the panoramic images, which is relatively mature, the data collection is inexpensive, light and handy in the total process, and it is could be adopted as panorama by open source. The experiments show that the hybrid method and the reconstructed object height proposed by the paper are much validated and something useful is obtained.
Einstein manifolds and conformal field theories

In light of the anti\char21{}de Sitter space conformal field theory correspondence, it is natural to try to define a conformal field theory in a large N, strong coupling limit via a supergravity compactification on the product of an Einstein manifold and anti\char21{}de Sitter space. We consider the five-dimensional manifolds ${T}^{\mathrm{pq}}$ which are coset spaces $[\mathrm{SU}(2)\ifmmode\times\else\texttimes\fi{}\mathrm{SU}(2)]/\mathrm{U}(1). $ The central charge and a part of the chiral spectrum are calculated, respectively, from the volume of ${T}^{\mathrm{pq}}$ and the spectrum of the scalar Laplacian. Of the manifolds considered, only ${T}^{11}$ admits any supersymmetry: it is this manifold which characterizes the supergravity solution corresponding to a large number of $D3$-branes at a conifold singularity, discussed recently by Klebanov and Witten. Through a field theory analysis of anomalous three point functions we are able to reproduce the central charge predicted for the ${T}^{11}$ theory by supergravity: it is $\frac{27}{32}$ of the central charge of the $\mathcal{N}=2{\mathbf{Z}}_{2}$ orbifold theory from which it descends via a renormalization group flow.
20 Interaction Manifestations in Multi-player Games

This chapter describes the findings of ethnographical research which elaborates and analyses the interaction forms of a contemporary multi-player game. The motivation for the research originates from the issue that the lack of intuitive and non-intrusive interaction cues is one of the distinctive features separating shared virtual environment settings from face-to-face encounters. The analysis of the interaction forms in a multi-player game session indicates that the participants of collaborative virtual environment can use various forms of nonverbal communication and perceivable actions to enhance the social presence. However, players tend to communicate outside the game system and they try to overcome the limitations of the systems by inventing various imaginative ways to communicate, co-ordinate and co-operate. This indicates that there is a need for additional interaction support.
Evolution of a Complex Locus: Exon Gain, Loss and Divergence at the Gr39a Locus in Drosophila

Background Gene families typically evolve by gene duplication followed by the adoption of new or altered gene functions. A different way to evolve new but related functions is alternative splicing of existing exons of a complex gene. The chemosensory gene families of animals are characterised by numerous loci of related function. Alternative splicing has only rarely been reported in chemosensory loci, for example in 5 out of around 120 loci in Drosophila melanogaster. The gustatory receptor gene Gr39a has four large exons that are alternatively spliced with three small conserved exons. Recently the genome sequences of eleven additional species of Drosophila have become available allowing us to examine variation in the structure of the Gr39a locus across a wide phylogenetic range of fly species. Methodology/Principal Findings We describe a fifth exon and show that the locus has a complex evolutionary history with several duplications, pseudogenisations and losses of exons. PAML analyses suggested that the whole gene has a history of purifying selection, although this was less strong in exons which underwent duplication. Conclusions/Significance Estimates of functional divergence between exons were similar in magnitude to functional divergence between duplicated genes, suggesting that exon divergence is broadly equivalent to gene duplication.
Simultaneous observations of the ionospheric footprint of flux transfer events and dispersed ion signatures

Abstract. We perform a case study of a favourable conjunction of overpasses of the DMSP F11 and F13 spacecraft with the field of view of the Hankasalmi HF coherent scatter. At the time, pulsed ionospheric flows (PIFs) were clearly observed at a high-latitude in the radar field of view. The PIFs were associated with medium spectral width values and were identified as the fossilized signatures of pulsed dayside reconnection. Simultaneously, DMSP spectrograms from the two spacecraft showed dispersed ion signatures, observed equatorwards of the PIF signatures. We identified dayside high-latitude magnetosphere boundaries; these boundaries agreed well with those defined using the algorithm on the JHU/APL auroral particle website (Haerendel et al., 1978; Newell and Meng, 1988, 1995; Newell et al., 1991a, 1991b, 1991c; Traver et al., 1991). We conclude that in this case study the dispersed ion signatures map to regions of very newly-opened flux. It is only when this flux has convected polewards that the signatures of the PIFs with medium spectral widths are observed by the HF radars. These particular PIF signatures map to regions of mantle precipitation, i.e. recently reconnected flux. Key words.

Governing a complex social system with system dynamics : the management and economics of an airport hub

Managing a hub successfully imply the interaction of numerous actors, both public and private operating at a local, national and international level. Such a complexity imply that, rather than the content of the single decision, it is important to understand those dynamics emerging from an articulated system of decisions. In order to improve the quality of the single decisions, it is required the ability to generate valid systemic conceptual models aimed at the understanding of the long term consequences, avoiding counterintuitive and undesirable results. This paper constitutes the outcome of the continuation of a research project started in 1999 and can be considered the result of the second evolution of the hub model. A first evalotion of the model had been presented in a paper written 2000. While the 2000 paper focused particularly on a hub creation, this paper focuses on hub management and the economic impact of managerial choices. The paper is articulated in three parts: The first is dedicated to the statement of the problem; dilemmas, possible strategies and key decisions related to the creation of a hub are discussed. In the second part the systemic conceptual model is presented with reference to a simulated European airport context. In the last section some consideration about the implication in terms of decision making, economic impact, the directions proposed by the model and the possibility to generalise it in other systemic context are explored.
Finite horizons and the twin deficits

This paper uses Blanchard's (1985) model to study the relationship between budget deficits and trade deficits. The model is applied to annual post-war data from the U.S., Japan, and Germany. I find that in all three countries there is a significant link between trade deficits and budget deficits, holding constant expected changes in GNP and government expenditure. However, the implied planning horizons are quite different across countries. In particular, the implied planning horizon in the U.S. is only about 3 to 4 years, whereas in Japan it is 71 years and in Germany it is 31 years.
Self-Replicating Sequences of Binary Numbers: The Build-Up of Complexity

A recently introduced system of self-replicating sequences of binary numbers (strings) is generalized. It is extended to include st rings of arbitrary length . For thi s purp ose, first , t he folding meth­ ods of st rings into two-dimensional operat ors are expanded to include strings of arbitr ary size. Second, rules of interact ion between str ings of different length s are established. As a natur al consequence of these int eractions, changes in st ring length are observed. Using an effective model of length changes, t he build-up of complexity as measured by t he average sequence length in a st ring population is st udied.
Leakage control techniques for designing robust, low power wide-OR domino logic for sub-130nm CMOS technologies

In this paper, we discuss the design of leakage tolerant wide-OR domino gates for deep submicron (DSM), bulk CMOS technologies. Technology scaling is resulting in 3-5x increase in transistor I/sub OFF///spl mu/m per generation resulting in 15%-30% noise margin degradation of high performance domino gates. We investigate several techniques that can improve the noise margin of domino logic gates and thereby ensure their reliable operation for sub-130nm technologies. Our simulations indicate that, selective usage of dual V/sub TH/ transistors shows acceptable energy-delay tradeoffs for the 90nm technology. However, techniques like supply voltage (V/sub cc/) reduction and using non-minimum L/sub c/ transistors are required in order to ensure robust and scalable wide-OR domino designs for the 70nm generation.
The Curse of Finiteness: Undecidability of Database-Inspired Reasoning Problems in Very Expressive Description Logics

Recently, the field of knowledge representation is drawing a lot of inspiration from database theory. In particular, in the area of description logics and ontology languages, interest has shifted from satisfiability checking to query answering, with various query notions adopted from databases, like (unions of) conjunctive queries or different kinds of path queries. Likewise, the finite model semantics is being established as a viable and interesting alternative to the traditional semantics based on unrestricted models. In this paper, we investigate diverse database-inspired reasoning problems for very expressive description logics (all featuring the worrisome triad of inverses, counting, and nominals) which have in common that role paths of unbounded length can be described (in the knowledge base or of the query), leading to a certain non-locality of the reasoning problem. We show that for all the cases considered, undecidability can be established by very similar means. Most notably, we show undecidability of finite entailment of unions of conjunctive queries for a fragment of SHOIQ (the logic underlying the OWL DL ontology language), and undecidability of finite entailment of conjunctive queries for a fragment of SROIQ (the logical basis of the more recent and popular OWL 2 DL standard).
Building the Process: Component-Based Workflow Architectures in a Distributed World

we ure x es, entof the ed ved ort INTRODUCTION Extensive work has been done, across a number of fields, in modeling organizational processes. A tension has existed between attempts to provide rich expression of organizational activities and a desire to support work as it actually takes places. There is the strong suggestion, backed up by observation, that the specification of many work activities is ad-hoc, based on the context in which the activity occurs. Typically, these diversions from the “ideal” process have been described as exceptions. The exception is tolerated, the work instance modified, or the model itself modified to address the inconsistency. For much of work activity, however, exceptions are the rule [6]. The process model serves as a way of describing the goal, rather than a guide for execution. To address this, some systems attempt to use more loosely coupled rule or event based approaches to model processes, but these tend to lack mechanisms for abstraction and describing well understood procedures.
Methodologies and Tools of the Modern (e-) Learning E-learning, E-practising and E-tutoring: an Integrated Approach

In this paper is described a didactic methodology combining current e-learning methods and the support of Intelligent Agents technologies. The aim is to favor the synthesis among theoretical approach and based practical approach using the so-called Intelligent Agent, software that exploits the Artificial Intelligence and that operates as tutor, facilitating the consumers in the training operations. The paper illustrates how such new Intelligent Agent algorithm (IA) is used in the training of employees working in the transportation sector, thanks to the experience gained with the PARMENIDE project-Promoting Advanced Resources and Methodologies for New Teaching and Learning Solutions in Digital Education.
Valorization of Cheese and Tofu Whey through Enzymatic Synthesis of Lactosucrose

This work deals with the development of a new bioprocess for the efficient synthesis of lactosucrose, a potential prebiotic oligosaccharide with a high value-added, from two important and inexpensive agro-industrial by-products such as tofu whey and cheese whey permeate. The bioconversion is driven by the ability of the enzyme levansucrase SacB from Bacillus subtilis CECT 39 to transfructosylate lactose contained in the cheese whey permeate by using not only sucrose but also raffinose and stachyose, which are present in considerable amounts in the tofu whey, as suitable donors of fructosyl moieties. The maximum lactosucrose concentration obtained from both by-products was 80.1 g L-1 after a short reaction time 120 min at 37°C, leading to productivity and specific productivity values of 40.1 g lactosucrose L-1 h-1 and 80.1 mg lactosucrose U enzyme−1 h−1, respectively. Findings contained in this work could provide a new strategy to valorize agro-industrial by-products as cheese whey permeate and, specially, tofu whey by means of their use as renewable resources in the enzymatic synthesis of bioactive oligosaccharides.
Journal of Theoretical and Applied Information Technology New Deterministic Code Matched Interleaver for Turbo Codes

Turbo codes offer extraordinary performance, especially at low signal to noise ratio, due to a low multiplicity of low weight code words. The interleaver design is critical in order to realize an apparent randomness of the code, thus further enhancing its performance especially for short block frames. This paper presents a new algorithm of obtaining a code matched interleaver leading to very high minimum distance and performances. The design method is described in depth, and the simulation results are plotted against the Long Term Evolution (LTE) standard interleaver.
Static Component Configuration Support for Real-Time Platforms

Component based approaches [1] are gaining increasing momentum in the development of software systems. Implementations of component models like EJB [2], COM [3] and the CORBA Component Model (CCM) [4] provide standard frameworks which isolate the functional concerns of a software system from para-functional concerns like transactions, security, realtime, etc. Each of the above component models defines details of the component development process implementation, packaging, deployment and configuration. The configuration of a component is separated from its implementation so that the same component can be run within different contexts. Apart from configuration, connection information between components is also specified so that components can be composed to realize the entire functionality of a system. In this position paper, we describe the component assembly process in the context of an open source implementation of the CORBA Component Model (CCM). We then describe extensions to component assembly to support the requirements of embedded real-time operating system (RTOS) platforms.
Taylor Expansion Diagrams : A Compact Canonical Representation for Arithmetic Expressions

This paper presents a new, compact, canonical representation for arithmetic expressions, called Taylor Expansion Diagram. It can be used to facilitate the verification of RTL specifications and hardware implementations of arithmetic designs, and specifically the equivalence checking of complex algebraic and arithmetic expressions that arise in symbolic verification. This new representation is based on an entirely new, non-binary decomposition principle. It treats the expression as a continuous, differentiable function over symbolic (algebraic) variables and applies Taylor series expansion recursively over its variables. The resulting Taylor Expansion Diagram (TED), is canonical for a fixed ordering of variables. We present a theory of TED, and show how to obtain the reduced, normalized representation. We demonstrate that it has linear space complexity for arbitrarily complex polynomials, while time complexity to generate the representation is comparable to that of *BMD. This is the first representation known to us that allows to represent complex arithmetic functions in linear space. We believe that the proposed representation will have serious impact on symbolic verification methods as it can significantly enhance the verification process for RTL designs containing arithmetic circuits.

Branching in the sequential folding pathway of cytochrome c

Previous results indicate that the folding pathways of cytochrome c and other proteins progressively build the target native protein in a predetermined stepwise manner by the sequential formation and association of native‐like foldon units. The present work used native state hydrogen exchange methods to investigate a structural anomaly in cytochrome c results that suggested the concerted folding of two segments that have little structural relationship in the native protein. The results show that the two segments, an 18‐residue omega loop and a 10‐residue helix, are able to unfold and refold independently, which allows a branch point in the folding pathway. The pathway that emerges assembles native‐like foldon units in a linear sequential manner when prior native‐like structure can template a single subsequent foldon, and optional pathway branching is seen when prior structure is able to support the folding of two different foldons.
