Towards an OpenID-based solution to the Social Network Interoperability problem

The main aim of this paper is to present the OpenPlatform, the Asemantics OpenID solution developed for several Italian web portals. Starting from the developers’ experience in the field of digital identity, this work also describes the Global Social Platform as an open-standard based solution to the Social Networks interoperability problem. Basically, it consists of a platform allowing users to aggregate their social graphs that are spread over a bunch of different social networks. The OpenID main concepts, such as the user Identity Page, are the foundational ideas behind the Global Social Platform since they can be considered as the unique place where information is stored. A set of Java API is provided in order to write Adapters and Converters that are, mainly, Global Social Platform plugins allowing third party developers to pull data from different data silos and showing them in several different formats.
T cell determinant structure: cores and determinant envelopes in three mouse major histocompatibility complex haplotypes

T lymphocytes recognize discrete regions on an antigen. The specificity of the T cell responses in three mouse strains of differing major histocompatibility complex (MHC) haplotype to a protein antigen, lysozyme, was analyzed using a series of peptides that walk the antigen in single amino acid steps. These peptide series were synthesized using the pin synthesis system, which was modified to allow the peptides to be cleaved from the pins into a physiological buffer free of toxic compounds. This methodology overcomes many of the problems associated with the production of peptides for screening proteins for antigenic determinants. The T cell determinants for the three strains were markedly different. This result points out the limitations of algorithms predicting determinants without reference to the MHC, and the importance of the empirical methodology. This analysis of the T cell response to lysozyme constitutes the most complete study of reactivity to a foreign protein to date and illustrates many important features of antigen recognition by T cells, e.g., presence of major and minor determinant regions. The outer boundaries of each immunogenic region, the determinant envelope, are difficult to define from recently immunized lymph nodes because of the heterogeneity in T cell recognition. However, core sequences common to all the immunogenic peptides in a continuous sequence can be easily defined.
Measures of charge fluctuations in nuclear collisions

The properties of two measures of charge fluctuations D and Delta Phi_q are discussed within several toy models of nuclear collisions. In particular their dependence on mean particle multiplicity, multiplicity fluctuations and net electric charge are studied. It is shown that the measure Delta Phi_q is less sensitive to these trivial biasing effects than the originally proposed measure D. Furthermore the influence of resonance decay kinematics is analysed and it is shown that it is likely to shadow a possible reduction of fluctuations due to QGP creation.
Towards a 2-hybrid Android malware detection test framework

Current pervasive usage of mobile devices around the world has rose big security and data protection concerns both into the application development process as into the data security field. Although the long way of development in PC security malware treatment in the computer science and industrial areas, mobile devices security research and development have proved that in this area malware treatment goes far beyond PC malware analysis and prevention techniques replication. In this context, this paper provides a description of a current open-ended project aimed to produce a 2-hybrid malware detection test framework. Based on the current trends of hybrid malware analysis, in this work the term 2-hybrid implies both a local(host)-remote(server/cloud) implementation and a static-dynamic analysis approach.
Evaluation of Liver Fibrosis: A Concise Review

The diagnosis of liver fibrosis has traditionally relied on liver biopsy. However, recent studies have suggested that there can be up to a 33 % error in the diagnosis of cirrhosis. In this article, we review the current status of liver biopsy as a gold standard for the diagnosis of liver fibrosis and discuss the radiological and serum tests that have been proposed as potential adjuncts or alternatives to biopsies. Indirect markers of liver fibrosis which reflect alterations in liver function and or inflammation are discussed as well as more direct markers of liver fibrosis. The limitations of utilization of these markers for both cross-sectional diagnosis of fibrosis and monitoring disease progression or regression are discussed.
Concepts and capabilities of a database computer\

The concepts and capabilities of a database computer (DBC) are given in this paper. The proposed design overcomes many of the traditional problems of database system software and is one of the first to describe a complete data-secure computer capable of handling large databases. This paper begins by characterizing the major problems facing today's database system designers. These problems are intrinsically related to the nature of conventional hardware and can only be solved by introducing new architectural concepts. Several such concepts are brought to bear in the later sections of this paper. These architectural principles have a major impact upon the design of the system and so they are discussed in some detail. A key aspect of these principles is that they can be implemented with near-term technology. The rest of the paper is devoted to the functional characteristics and the theory of operation of the DBC. The theory of operation is based on a series of abstract models of the components and data structures employed by the DBC. These models are used to illustrate how the DBC performs access operations, manages data structures and security specifications, and enforces security requirements. Short Algol-like algorithms are used to show how these operations are carried out. This part of the paper concludes with a high-level description of the DBC organization. The actual details of the DBC hardware are quite involved and so their presentation is not the subject of this paper. A sample database is included in the Appendix to illustrate the working of the security and clustering mechanisms of the DBC.
MIMIC: real-time marker-free motion capture system to create an agent in the virtual space

The authors describe a real-time 3D computer vision system called MIMIC (Motion Interface & Motion Information Capture system) that can capture and save the motion of an actor. This system analyzes input images from vision sensors and searches feature information like a head, hands, and feet. Moreover, this estimates intermediated joints as an elbow and knee using feature information and makes a 3D human model having 20 joints. This virtual human model mimics the motion of an actor in realtime. Therefore this system can realize the movement of an actor unaffectedly because of making intermediated joint for complete human body contrary to other marker-free motion capture systems.
Validating Inconsistent Requirements Models using Graph-based Abduction

Multiple viewpoints are often used in requirements engineering to facilitate traceability to stakeholders, to structure the requirements process, and to provide richer modeling by incorporating multiple con icting descriptions. Toleration of inconsistency is a key advantage. However, inconsistency introduces considerable extra complexity when reasoning about requirements. This complexity may limit our ability to maintain a lazy approach to consistency management when we want to validate requirements models. In this paper, we describe a series of experiments with graph-based abduction for multiple world reasoning over inconsistent requirements models. Our abductive algorithm, HT4, sorts an inconsistent model into a number of consistent worlds that support answers to speci c queries about the model. This approach avoids the trivialization that occurs in classical deductive inference in the presence of inconsistency. Experiments with this approach reveal that surprisingly few worlds are generated. This result is robust over a range of di erent models, di erent amounts of data available from the domain, and di erent modeling primitives for representing time. To explore the implications of this result, we developed a second algorithm, HT0, that extracts a single world at random from an inconsistent model. Experimentally, HT0 runs fast even for very large models, and supports most of the queries addressed by HT4. The paper discusses possible reasons for this nding, and the implications it has for software engineering in general. We conclude that it is not diÆcult to support reasoning in the presence of inconsistency even in large models.
A parallel algorithm for constrained fixed two-staged two-dimensional cutting/packing problems

This paper proposes a parallel cooperative algorithm for approximately solving the constrained fixed (non-oriented) two-staged two-dimensional two-dimensional cutting/packing problem. The proposed algorithm considers three key features: a search strategy based on beam-search, a fast filling procedure based on strip generation, and a tighter upper bound applied for refining the selected paths. The algorithm explores, in parallel, a subset of elite nodes following the master-slave paradigm. The master processor guides the search-resolution by maintaining a global list while each slave processor develops its own path according to its internal lists and an internal processor that completes the global paths. The computational investigation shows the good performance of the proposed algorithm which either matches the optima or improves the best known solution values within a reduced runtime.
MAP-PSP for Space-Time Trellis Codes Over Unknown Doppler Channels

This work considers joint channel estimation and data detection of space-time trellis codes (STTCs) over time-varying flat fading channels with unknown normalized Doppler shift, <i>f</i> <sub>d</sub>T. An algorithm based on an improved per survivor processing (PSP) technique, where the survivor branch decision is formulated in the symbol by symbol maximum a posteriori probability (MAP) framework, is presented. An adaptive Kalman predictor (AKP) is employed to track the fading channel and <i>f</i> <sub>d</sub>T. In the AKP, the sequence of channel estimates produced by the Kalman predictor (KP) is utilized for <i>f</i> <sub>d</sub>T estimation. In turn, the estimated <i>f</i> <sub>d</sub>T is used in the KP for channel tracking. This coupled process adaptively estimates both the channel coefficients and Doppler shift. The performance of STTC using the proposed receiver is robust against <i>f</i> <sub>d</sub>T mismatch, and it is within 0.3 dB from the known <i>f</i> <sub>d</sub>T case.
Study and design of adaptation circuit of a tendering system for measuring the bio-impedance

This article consists on measuring bio-impedance that reflects biological and clinical information useful for the tissue characterization and diseases detection etc. The objective of this article is to adapt the programmable impedance meter AD5933/34EBZ for measuring bioimpedance by the tetra-polar configuration. This method allows direct measurement of the impedance of the sample without the electrode impedances and impedance of interface skin/electrode. This paper also allows to overcome the drawbacks of the evaluation kit and to set the parameters of the various components of the adaptation circuit.
Description of a Novel Anatomic Venous Structure in the Nasoglabellar Area

AbstractInjectable dermal fillers are frequently used to reduce the appearance of various facial creases and rhytids. However, venous complications can develop while injecting dermal filler, especially in the nasoglabellar area. The aims of this study were to determine the anatomic patterns of the veins in the nasoglabellar area and to elucidate their detailed location with reference to various facial landmarks. Forty-one heads from Korean and Thai cadavers were dissected. When the anastomosing vein between the bilateral angular veins (AVs) was located in the nasoglabellar area, it was designated the intercanthal vein (ICV). The bilateral AVs continued as the facial vein without any communicating branches in 12 cases (29.3%). At the radix of the nose, the AV communicated with the ICV, connecting them bilaterally. The ICV was found above (type IIA) and below (type IIB) the intercanthal line in 26 (63.4%) and 3 (7.3%) cases, respectively. The ICV can be regarded as a candidate causative site for the frequent complications associated with dermal filler injection in the nasoglabellar area, and utmost care should be taken when injecting in this area, such as when performing radix augmentation and softening wrinkles in the glabellar area.
Trace select: acquiring remote targets with gesture guides generated from glyphs

When selecting targets in a Smart TV service, the user is frequently required to select remote targets such as menu items, but is unable to touch the targets directly or use a mouse. Solutions include rapid selection techniques using gesture guides. However, such techniques create difficulties, in that they tend to hide the original information. This study proposes a novel technique for selecting remote targets, referred to as Trace Select, which dynamically generates gesture guides from text target characters. The guides do not conceal the original targets. As a result, the guides can be continuously displayed. The technique does not require immediate activation of the gesture-guide displays, and users can identify and draw the gesture of the desired target at any time. Experiments show that Trace Select outperforms both cursor-based selection enhanced by acceleration and conventional activation-required gestural selection.
Position sensorless control for PMSM using sliding mode observer and phase-locked loop

In this paper, a novel sliding mode observer is presented for achieving the position sensorless vector control based on estimating the rotor position of permanent magnet synchronous machines. Compared to conventional sliding mode observer (smo), the proposed observer based on sliding mode observer and phase-locked loop (pll) can effectively reduce the influence of the sliding mode chattering and improve the precision of the rotor position estimation. The results of simulation show that the novel sliding mode observer is more effective than the conventional method.
Mechanisms of cross hyporesponsiveness to Toll-like receptor bacterial ligands in intestinal epithelial cells.

BACKGROUND & AIMS Despite the ability to participate in immune responses and the continuous presence of bacteria and bacterial products, functional responses of intestinal epithelial cells (IEC) seem to be muted. Previously, tolerance to Toll-like receptors (TLRs) ligands has been described in monocytic cells. However, mechanisms in the intestine are unknown. METHODS The effect of purified lipopolysaccharide (LPS) and lipoteichoic acid (LTA) on expression and function of TLRs in intestinal epithelial cells (Colo205, SW480, T84) was assessed by Northern and Western blot and FACS analysis, kinase activity assays, immunohistochemistry, and ELISA. RESULTS Expression of TLRs except 10 was detected in primary IEC and TLR1-10 in the cultured cells. Short-term stimulation with LPS or LTA activated proinflammatory signaling cascades in IEC, including phosphorylation of IRAK and MAP kinases and increased IL-8 secretion, whereas prolonged incubation resulted in a state of hyporesponsiveness with no reactivation of the cells by a second challenge with either substance detected. The cells remained responsive to tumor necrosis factor (TNF). Hyporesponsive cells showed no alteration in expression of TLR or signaling molecules but revealed a decrease in TLR surface expression and IRAK activity. Toll-interacting protein (Tollip) mRNA and protein expression were increased in hyporesponsive cells, and overexpression of Tollip in IEC resulted in a significantly decreased proinflammatory response. CONCLUSIONS Continuous presence of specific bacterial components results in a status of hyporesponsiveness in otherwise reactive IEC. Down-regulation of TLR surface expression and up-regulation of inhibitory Tollip with decreased phosphorylation of IRAK might all contribute to this hyporesponsiveness.
C-C Chemokine Receptor Type 2 Expression on Monocytes Before Sepsis Onset Is Higher Than That of Postsepsis in Septic Burned Patients: A New Predictor for Sepsis in Burned Injury

Objective: The present study aims to investigate the alterations in monocytes (Mo) and dendritic cells (DCs) in septic burned patients with a special focus on C-C chemokine receptor type 2 (CCR2) expressions on classical Mo. Background: The phenotypes of Mo and DCs, particularly CCR2 expression on Mo, are not fully explored in severely burned patients with sepsis. Methods: The prospective cohort study was conducted in Ross Tilley Burn Centre and Sunnybrook Research Institute (Toronto, Canada). We enrolled 8 healthy patients and 89 burned patients with various burned sizes, of those burned patients, 12 were with sepsis. Blood was collected upon admission to the hospital and throughout their course in hospital. The expression of human leukocyte antigen-DR was determined on all DCs and Mo, along with CCR2 on CD14++/CD16− Mo. Results: We found a profound decrease in human leukocyte antigen-DR on Mo and DCs in burned patients with sepsis compared with healthy controls and nonseptic burned patients. In addition, septic burned patients presented an increased CCR2 expression on classical Mo (CD14++/CD16−), which was paralleled by greater chemokine (C-C motif) ligand 2 concentrations in the plasma when compared with controls and nonseptic burned patients. Furthermore, burned patients with sepsis had a more profound expansion of CD14++/CD16+ Mo when compared with nonseptic burned patients. Conclusion: Our results demonstrate that burned patients with sepsis have more profound impairment of monocytes and dendritic cells than burned patients without sepsis. With CCR2 level on Mo before sepsis onset being higher than postsepsis, CCR2 expression could be a new predictor of sepsis onset in severe burn injury.
Dl difference test; improved method for clinical measurement of recruitment.

THE RECRUITMENT of loudness phenomenon, first described by Fowler, 1 has been known for over two decades, but its practical significance has only recently been discovered. Otologists have long recognized that certain patients experience an abnormally rapid increase in loudness when the intensity of sound is raised above their impaired threshold, but for many years it was thought that this recruitment was the inevitable accompaniment of all perceptive, as opposed to conductive, hearing loss. The discovery by Dix, Hallpike, and Hood 2 that recruitment is present only in lesions of the sensory receptor mechanism, i. e. , hair cells and organ of Corti, has, in general, precipitated a renewed interest in this remarkable phenomenon, and, in particular, has emphasized the need for a simple, easily administered test of recruitment for clinical purposes. It has been recognized that such a tool would constitute a valuable addition to the otologist's armamentarium by allowing

The Influence of Emotion on Fairness-Related Decision Making: A Critical Review of Theories and Evidence

Fairness-related decision making is an important issue in the field of decision making. Traditional theories emphasize the roles of inequity aversion and reciprocity, whereas recent research increasingly shows that emotion plays a critical role in this type of decision making. In this review, we summarize the influences of three types of emotions (i.e., the integral emotion experienced at the time of decision making, the incidental emotion aroused by a task-unrelated dispositional or situational source, and the interaction of emotion and cognition) on fairness-related decision making. Specifically, we first introduce three dominant theories that describe how emotion may influence fairness-related decision making (i.e., the wounded pride/spite model, affect infusion model, and dual-process model). Next, we collect behavioral and neural evidence for and against these theories. Finally, we propose that future research on fairness-related decision making should focus on inducing incidental social emotion, avoiding irrelevant emotion when regulating, exploring the individual differences in emotional dispositions, and strengthening the ecological validity of the paradigm.
Motion Detection Based on Background Modeling and Performance Analysis for Outdoor Surveillance

Real-time segmentation of moving objects in video sequences is a fundamental step for surveillance systems. One of successful methods for complex background is to use a multi-color background model per pixel. However, Common problem for this approach is that it suffers from illumination changing environment, in addition, it is incapable of removing shadows of moving objects. This paper proposed an effective scheme to improve the adaptive background model for each pixel by introducing a background training parameter into every Gaussian model, and region-based scheme is applied to judgment by utilizing both spatial and temporal information. Experimental results will be presented to validate proposed algorithm keep robustness in the situation of illumination changes, shadow can be removed in foreground mask, results shows False Alarm Rate can be reduced from 34.9% to 35.8% while the overlap varies within normal range from 0.4 to 0.6 compared with conventional Gaussian mixture model.
The Wedding the Carp and the Rabbit: A Realist Stand for an Ontology of Social Facts and Organizational Objects

The paper wishes to define and defend a moderate version of realism which we call modal realism. The difference between ontology and epistemology is first pointed out and we focus on the ontological side. We think it is often neglected because ontological issues are often assimilated to epistemological ones. We try to fill this gap in literature by defining an ontological level of reasoning. We then offer a test for the opposing camps in ontology: that of constructionism and that of realism by taking an example that can be interpreted both ways: the controversial merger of Snecma and Sagem into Safran, a French conglomerate. A merger raises ontological questions, merging being in itself an ontological process of two becoming one. Dwelling on the importance of this ontological issue, we then offer a presentation of modal realism. We once again depart from the merger case to show how this realism allows for a flexible and dynamics vision of reality, accounting for the “vague” and multilayered dimensions of social objects. It proposes a scale of beings, relations and combinations via “layered dimensions” in a modal ensemble. Throughout the example of the different levels of commitment, we hope to present a thorough description of modal realism as a matter-of-fact approach aimed at capturing the subtle dimensions of social objects such as organisations.
