Architectural survey of context-aware systems in pervasive computing environment

The main characteristic of devices in a pervasive (or ubiquitous) computing system is their context awareness which allows them to provide proactively adapted services to user and to applications according to the global context. In order to support the development and to ease the implementation of context-aware systems, many architectures were proposed with characteristics related to the application domain and techniques used. A survey of such architectures that makes comparison between them and evaluates them is strongly recommended. Proposed surveys are either restricted to a limited number of architectures or do not offer a good comparison or their evaluation is not based on appropriate criteria which keep them as simple descriptions. Our aim is to make a survey of relevant architectures which mark the evolution of context-aware systems based on criteria related to pervasive computing. This survey will serve as a guide to developers of context-aware systems and help them to make architectural choices.
Characterization of a mammalian prosencephalic functional plan

Hypothalamic organizational concepts have greatly evolved as the primary hypothalamic pathways have been systematically investigated. In the present review, we describe how the hypothalamus arises from a molecularly heterogeneous region of the embryonic neural tube but is first differentiated as a primary neuronal cell cord (earliest mantle layer). This structure defines two axes that align onto two fundamental components: a longitudinal tractus postopticus(tpoc)/retinian component and a transverse supraoptic tract(sot)/olfactory component. We then discuss how these two axonal tracts guide the formation of all major tracts that connect the telencephalon with the hypothalamus/ventral midbrain, highlighting the existence of an early basic plan in the functional organization of the prosencephalic connectome.
The Chern character of the Verlinde bundle over ℳ¯ g,n

We prove an explicit formula for the total Chern character of the Verlinde bundle of conformal blocks over Mg;n in terms of tautological classes. The Chern characters of the Verlinde bundles define a semisimple CohFT (the ranks, given by the Verlinde formula, determine a semisimple fusion algebra). According to Teleman’s classification of semisimple CohFTs, there exists an element of Givental’s group transforming the fusion algebra into the CohFT. We determine the element using the first Chern class of the Verlinde bundle on the interior Mg;n and the projective flatness of the Hitchin connection.
Advanced Echocardiographic Imaging of the Congenitally Malformed Heart

There have been significant advancements in the ability of echocardiography to provide both morphological and functional information in children with congenitally malformed hearts. This progress has come through the development of improved technology such as matrix array probes and software which allows for the off line analysis of images to a high standard. This article focuses on these developments and discusses some newer concepts in advanced echocardiography such is multi-planar reformatting [MPR] and tissue motion annular displacement [TMAD]. Our aim is to discuss important aspects related to the quality and reproducibility of data, to review the most recent published data regarding advanced echocardiography in the malformed heart and to guide the reader to appropriate text for overcoming the technical challenges of using these methods. Many of the technical aspects of image acquisition and post processing have been discussed in recent reviews by the authors and we would urge readers to study these texts to gain a greater understanding [1]. The quality of the two dimensional image is paramount in both strain analysis and three dimensional echocardiography. An awareness of how to improve image quality is vital to acquiring accurate and usable data. Three dimensional echocardiography (3DE) is an attempt to visualise the dynamic morphology of the heart. Although published media is the basis for theoretical knowledge of how to practically acquire images, electronic media [eg.www. 3dechocardiography.com] is the only way of visualising the advantages of this technology in real time. It is important to be aware of the limitations of this technology and that much of the data gleaned from using these methods is at a research stage and not yet in regular clinical practice.

Vision-based motion tracking rehabilitation system for gait disorder

Aim of the present study was to review the articles for the vision-based motion tracking, usually applied on the rehabilitation systems of gait disorder. Based on our ultimate goal, we searched several articles, available from the online database of some journals and conferences, published in the English language between January, 1993 and June, 2012. We especially searched for the phrases, such as “vision sensor”, “motion tracking”, “gait disorder”, and “rehabilitation” in the title, abstract, or keywords sections. Besides, some common synonyms of these phrases, along with the logical words, like “and”, “or”, and “not” were also used in the article searching procedure. From among the 37 articles found, this review identified 25 articles, which utilized the marker during video recording for motion tracking of the subject; whereas about 10 articles did not utilize any marker, 1 article utilized both marker-based and markerless, and another 1 articles were unrelated to the motion tracking but related to the gait disorder. Moreover, through this literature, we presented a strong evidence that enabled the analysis of motion tracking by the help of vision sensor for the rehabilitation systems of gait disorder. Hence, we believe that the information contained in this review will remarkably assist and guide the progress of the vision-based motion tracking, applied on the rehabilitation systems of gait disorder.
Prosodically-based automatic segmentation and punctuation

This work explores prosodic/acoustic cues for improving a baseline phone segmentation module. The baseline version is provided by a large vocabulary continuous speech recognition system. An analysis of the baseline results revealed problems in word boundary detection, that we tried to solve by using postprocessing rules based on prosodic features (pitch, energy and duration). These rules achieved better results in terms of interword pause detection, durations of silent pauses previously detected, and also durations of phones at initial and final sentencelike unit level. These improvements may be relevant not only for retraining acoustic models, but also for the automatic punctuation task. These two tasks were evaluated. Results based on more reliable boundaries are promising. This work allows us to tackle more challenging problems, combining prosodic and lexical features for the identification of sentence-like units.
White Supremacy, Patriarchy, and Global Capitalism in Migration Studies

Ten years after sociologist Mary Romero lamented the “ideological and theoretical gulf between immigration research and the sociology of race,” researchers have begun to bridge this theoretical gulf by centering critical race theory in studies of migration. Building on these analyses, this article argues that migration flows and immigrant incorporation are shaped not only by white supremacy but also by patriarchy and global capitalism. Insofar as migrants, predominantly from the Global South, are usually racialized as non-white, and come to work in a labor market shaped by exploitation, oppression, and patriarchy, it is critical to think of migrant flows and settlement within the context of what bell hooks describes as a White supremacist capitalist patriarchy. We draw from examples from our research with a broad spectrum of migrants and their children to elucidate how these three systems of oppression shape the experiences of migrants.
D-branes in Yang-Mills theory and emergent gauge symmetry

Four-dimensional supersymmetric SU(N) Yang-Mills theory on a sphere has highly charged baryon-like states built from anti-symmetric combinations of the adjoint scalars. We show that these states, which are equivalently described as holes in a free fermi sea of a reduced matrix model, are D-branes. Their excitations are stringlike and effectively realize Dirichlet and Neumann boundary conditions in various directions. The low energy brane dynamics should realize an emergent gauge theory that is local on a new space. We show that the Gauss' Law associated to this emergent gauge symmetry appears from combinatorial identities relating the stringy excitations. Although these excitations are not BPS, they can be near-BPS and we can hope to study them in perturbation theory. Accordingly, we show that the Chan-Paton factors expected for strings propagating on multiple branes arise dynamically, allowing the emergent gauge symmetry to be non-abelian.

The [Fe-Fe]-Hydrogenase Maturation Protein HydF from Thermotoga maritima Is a GTPase with an Iron-Sulfur Cluster*

The active site of [Fe-Fe]-hydrogenases is composed of a di-iron complex, where the two metal atoms are bridged together by a putative di(thiomethyl)amine molecule and are also ligated by di-nuclear ligands, namely carbon monoxide and cyanide. Biosynthesis of this metal site is thought to require specific protein machinery coded by the hydE, hydF, and hydG genes. The HydF protein has been cloned from the thermophilic organism Thermotoga maritima, purified, and characterized. The enzyme possesses specific amino acid signatures for GTP binding and is able to hydrolyze GTP. The anaerobically reconstituted TmHydF protein binds a [4Fe-4S] cluster with peculiar EPR characteristics: an S = 1/2 signal presenting a high field shifted g-value together with a S = 3/2 signal, similar to those observed for [4Fe-4S] clusters ligated by only three cysteines. HYSCORE spectroscopy experiments were carried out to determine the nature of the fourth ligand of the cluster, and its exchangeability was demonstrated with the formation of a [4Fe-4S]-imidazole complex.
Public Policies for Productive Innovation in Knowledge Society

This paper refers the advances of an ongoing project: "Local Development and Productive Innovation in three cities in the Province of Buenos Aires". Its main goal is to examine the relationships between public policies in dissimilar-sized cities and the processes of socio-technical innovation based on Information and Communication Technologies (ICTs). It spotlights the shaping factors on the rise and consolidation of innovation processes, the articulation between innovation agents, the role of the State, and the resulting explicit and implicit public policies. The main factors considered are the population number and characteristics of each city, the participation of innovation agents (Universities active in R+D, cutting-edge enterprises, innovative local governments), and the building productive innovation networks among them. The main final output of the project will be a set of recommendations addressed to regional and local governments about public policies for cities in Knowledge Society.
Az európai gazdasági kormányzás előtt álló kihívások. A hármas tagadás lehetetlensége (Challenges of European economic governance. The impossible trinity of denial.)

Accordingly, the European Monetary System was built upon a mix of a fixed exchange-rate regime and an autonomous monetary policy, thereby constraining capital mobility. In launching the EMU project, the EU countries decided to fix national currencies irrevocably and maintain full capital mobility, in exchange for delegating their monetary policy upwards to a supranational level. The introduction of the Euro zone, however, has simultaneously meant denial of the following three elements: (1) exit, (2) bail-out, and (3) default. Nevertheless, the 2008–9 financial and economic crisis has demonstrated mercilessly that these three pillars are incompatible with each other. So the current debates on reshaping economic governance in the EU can be modelled by introducing the “impossible trinity of denial”, concentrating on the benefits and the costs of each option.
A closed-form solution for a two-view self-calibration problem under fixation

It is well known that the epipolar geometry between two uncalibrated perspective views is completely encapsulated in the fundamental matrix. Since the fundamental matrix has seven degrees of freedom (DOF), self-calibration is possible if at most seven of the intrinsic or extrinsic camera parameters are unknown by extracting them from the fundamental matrix. This work presents a linear algorithm for self-calibrating a perspective camera which undergoes fixation, that is, a special motion in which the camera's optical axis is confined in a plane. Since this fixation has four degrees of freedom, which is one smaller than that of general motion, we can extract at most three intrinsic parameters from the fundamental matrix. We here assume that the focal length (1 DOF) and the principal point (2 DOF) are unknown but fixed for two views. It will be shown that these three parameters are obtained from the fundamental matrix in an analytical fashion and a closed-form solution is derived. We also characterize all the degenerate motions under which there exists an infinite set of solutions.
Self-efficacy, Learning Styles and Academic Performance in Students from Three Universities in Peru, by Gender

The objective of the study was to determine the significant differences in the learning styles, self-efficacy and academic performance perceived in students of three public universities of Peru according to gender, as well as to establish the differences in the dimensions of the learning styles: reflexive observation, conceptualization abstract, concrete experience and active experimentation. The sample was constituted by 474 students of Education and Psychology of the public universities of Lima, Huánuco and Cuzco, 326 women and 148 randomly selected men. The design was comparative descriptive, the instruments were the Scale of Specific Perceived Self-Efficacy of Academic Situations (EAPESA, Palenzuela, 1983) adapted by Escurra, (1989), the Inventory of Learning Styles built by Kolb in 1975 adapted by Escurra (1992) with reliability of 0.91. The academic performance was determined with the average percentages of semester grades 2017-I, of the students in the sample. The results established significant differences in self-efficacy according to gender, with a size of Cohen d of 0.312 (95% CI: 0.131-0.494) and in academic performance with 0.278 (95% CI: 0.096-0.459) with small size; while in the learning styles and their dimensions no significant differences were found.
Firm Size and Cyclical Variations in Stock Returns

Recent imperfect capital market theories predict the presence of asymmetries in the variation of small and large firms' risk over the economic cycle. Small firms with little collateral should be more strongly affected by tighter credit market conditions in a recession state than large, better collateralized ones. This paper adopts a flexible econometric model to analyze these mplications empirically. Consistent with theory, small firms display the highest degree of asymmetry in their risk across recession and expansion states, which translates into a higher sensitivity of their expected stock returns with respect to variables that measure credit market conditions.

Artificial Neural Network Based Segmentation Algorithm for Off-line Handwriting Recognition

Artificial Neural Networks (ANNs) have been successfully applied to Optical Character Recognition (OCR) yielding excellent results. This paper presents a method for segmentation of difficult handwriting with the use of conventional algorithms in conjunction with ANNs. The segmentation algorithm is heuristic in nature detecting important features which may represent a prospective segmentation point. An Artificial Neural Network is subsequently used to verify the authenticity of the segmentation points found by the algorithm. The C programming language, the SP2 supercomputer and a SUN workstation were used for the experiments. The algorithm has been tested on real-world handwriting obtained from the CEDAR database. Some preliminary experimental results are presented in this paper.
Beteiligungsorientierte Organisation und Innovation

Einer möglichst breiten Einbeziehung von Beschäftigten in betriebliche Innovationsprozesse wird in der aktuellen Innovationsforschung große Bedeutung für den Innovationserfolg beigemessen. Ihr Wissen und ihre Erfahrung gelten als zentrale Komponenten betrieblicher Innovationsfähigkeit (Tidd/Bessant 2009; Chesbrough 2006). Wir fragen nach dem Zusammenhang zwischen betrieblicher Mitbestimmung und Innovation, d. h. nach Wegen, wie das Erfahrungswissen der Beschäftigten aktiviert und in betriebliche Innovationsprozesse eingebracht werden kann. Im vorliegenden Beitrag untersuchen wir mit statistischen Methoden, wie sich diese Aktivierung im Rahmen der Nutzung beteiligungsorientierter Organisationsund Managementkonzepte sowie einer breiten Verankerung von Innovationskompetenz auf die betriebliche Innovationsfähigkeit auswirkt.2 Aus ressourcenorientierter Perspektive (Teece et al. 1997; Barney et al. 2001; Burr 2004) betrachtet, sind die internen Ressourcen und Fähigkeiten eines Unternehmens – und somit endogene Faktoren, nicht vorrangig die Positionierung des Unternehmens am Absatzmarkt – entscheidend für den Markterfolg und die langfristige Wettbewerbsfähigkeit, zu der maßgeblich auch Innovationen beitragen. Das Wissen der Mitarbeiter stellt hierbei einen der wichtigsten Aspekte dar.

Cultural heritage: Displaying the Forum of Nerva with new technologies

This paper outlines the results of current research in reconstruction and popularisation of the Nerva Forum in Rome, dating from imperial Rome and the high medieval period, which aroused interest in terms of technological innovation applied to communication of cultural heritage through navigation in “real time” and use of “augmented reality. ” Through Blender and its internal “game engine”, it was possible to innovatively experiment with real time navigation using the 3D model for reconstruction of the Forum in the two periods considered, with the possibility of quickly switching between models to verify analogies and differences between the historical periods reviewed, in addition to interacting and displaying some descriptive evidence of major objects in the Forum.
Myeloma Responses and Tolerance Following Combined Kidney and Nonmyeloablative Marrow Transplantation: In Vivo and In Vitro Analyses

Six patients with renal failure due to multiple myeloma (MM) received simultaneous kidney and bone marrow transplantation (BMT) from HLA‐identical sibling donors following nonmyeloablative conditioning, including cyclophosphamide (CP), peritransplant antithymocyte globulin and thymic irradiation. Cyclosporine (CyA) was given for approximately 2 months posttransplant, followed by donor leukocyte infusions. All six patients accepted their kidney grafts long‐term. Three patients lost detectable chimerism but accepted their kidney grafts off immunosuppression for 1.3 to >7 years. One such patient had strong antidonor cytotoxic T lymphocyte (CTL) responses in association with marrow rejection. Two patients achieved full donor chimerism, but resumed immunosuppression to treat graft‐versus‐host disease. Only one patient experienced rejection following CyA withdrawal. He responded to immunosuppression, which was later successfully withdrawn. The rejection episode was associated with antidonor Th reactivity. Patients showed CTL unresponsiveness to cultured donor renal tubular epithelial cells. Initially recovering T cells were memory cells and were enriched for CD4+CD25+ cells. Three patients are in sustained complete remissions of MM, despite loss of chimerism in two. Combined kidney/BMT with nonmyeloablative conditioning can achieve renal allograft tolerance and excellent myeloma responses, even in the presence of donor marrow rejection and antidonor alloresponses in vitro.
