Prediction-based concurrency control for a large scale networked virtual environment supporting various navigation speeds

Shared sense of a virtual world is often enhanced by replicating the information at each user's site since replication provides acceptable interactive performance, especially when users are geographically distributed over large networks like the Internet. However, multiple concurrent updates may lead to inconsistent views among replicas. Therefore concurrency control is a key factor to maintaining a consistent state among replicas. We proposed a scalable prediction-based scheme in which an ownership request is multicasted to only the users surrounding a target entity. In our previous work, we assumed that all the users navigate a virtual world with a single speed. It, however, is quite common in a networked virtual environment like a network game that users are allowed to change their navigation speed as they interact with a virtual world for adding more realism. This paper proposes an enhancement to support users with various speeds. The enhanced scheme allows as many Entity Radii as the number of different speed and allocates a separate queue for users of each speed. Each queue is examined in parallel to predict the next owner candidate and among the selected candidates is chosen the final candidate, which has a minimum predicted collision time. It contributes to the timely advanced transfer of ownership by using appropriate Entity Radius based on a user's speed, fair granting of ownership by reducing the interference between users with different speed and latency, and high prediction accuracy by reducing the redundant ownership transfer.
Real-time anomaly traffic monitoring based on dynamic k-NN cumulative-distance abnormal detection algorithm

In recent years, the scale of mobile Internet is rapidly increasing because of the explosive growing of smartphone users and applications. The traffic analysis and anomaly detection become critical for mobile operators. Up to now, there are a number of studies for detecting anomaly network traffic. However, the way of detecting anomalies on massive traffic data in real-time manner is not well studied. In this paper, we propose a real-time anomaly detection method based on dynamic k-NN cumulative-distance abnormal detection algorithm. We also present the design and implementation of the method by leveraging Strom, a distributed steam computing technology. Experimental results from evaluation by real-world dataset show that our system is a promised solution for real-time anomaly detection solution in high-speed network.
Retrieval of percussion gestures using timbre classification techniques

Musicians are able to recognise the subtle differences in timbre produced by different playing techniques on an instrument, yet there has been little research into achieving this with a computer. This paper will demonstrate an automatic system that can successfully recognise different timbres produced by different performance techniques and classify them using signal processing and classification tools. Success rates over 90% are achieved when classifying snare drum timbres produced by different playing techniques.
Diquarks as Inspiration and as Objects

It is plausible that several of the most profound aspects of low-energy QCD dynamics are connected to diquark correlations, including: paucity of exotics (which is the foundation of the quark model and of traditional nuclear physics), similarity of mesons and baryons, color superconductivity at high density, hyperfine splittings, $\Delta I = 1/2$ rule, and some striking features of structure and fragmentation functions. After a brief overview of these issues, I discuss how diquarks can be studied in isolation, both phenomenologically and numerically, and present approximate mass differences for diquarks with different quantum numbers. The mass-loaded generalization of the Chew-Frautschi formula provides an essential tool.
Pregnancy and Long-Term Maternal Cardiovascular Health: Progress Through Harmonization of Research Cohorts and Biobanks.

In 2011, the American Heart Association added preeclampsia, gestational diabetes mellitus (GDM), and delivery of a growth-restricted child as pregnancy-related risk factors for cardiovascular disease (CVD). 1 This move was applauded by the obstetric research community, which for some years had emphasized the importance of pregnancy as a stress test for detecting women at excessive risk for premature CVD.2–4 CVD is the leading cause of death for men and women in high-income and most low-to-middle–income countries.5 Globally, coronary artery disease kills more women than men,6 although women develop CVD 10 to 15 years later than men. Women frequently present with unrecognized CVD symptoms and are twice as likely as men to die of a first acute myocardial infarction if <50 years old.7 The preclinical stages of CVD are evident from a young age and are modifiable through control of classic risk factors (insulin resistance/diabetes mellitus, obesity, lack of exercise, tobacco smoking, hypertension, and hyperlipidemia). 8,9 In this regard, pregnancy is a window of opportunity for identifying those women with perinatal complications who may benefit from early risk detection and early CVD prevention. In this article, we summarize the associations between pregnancy, placenta-related pregnancy complications, and future maternal CVD. We present established as well as more novel hypotheses, which may explain these epidemiological associations. The interventions that potentially could reduce risks of future CVD are enumerated. To facilitate progress, we suggest methods of harmonizing study designs, long-term follow-ups of pregnancy cohorts and biobanks, and pooling of the world’s data in ways that can enhance the power of current and future research. ### Preeclampsia and Fetal Growth Restriction and Future CVD Risk Preeclampsia is a pregnancy-specific multisystem disorder defined by new-onset hypertension and proteinuria after gestational week 20, or new onset preeclampsia-associated signs in the absence of proteinuria.8 Preeclampsia requires the presence of …
Informativeness of NGS Analysis for Vaginal Fluid Identification

The identification of vaginal fluids in forensic examinations plays an important role in crime scene reconstruction. Molecular detection of vaginal bacterial communities can lead to the correct discrimination of body fluids. These kinds of studies can be performed through multiplex real‐time PCR using primers for a specific selection of bacteria. The availability of next‐generation sequencing (NGS) protocols provided for the extension of the analysis to evaluate the prokaryotes present in specimens. In this study, DNA was extracted from 18 samples (vaginal, oral, fecal, yoghurt) and analyzed by real‐time PCR and NGS. The comparison between the two approaches has demonstrated that the information developed through NGS can augment the more conventional real‐time PCR detection of a few key bacterial species to provide a more probative result and the correct identification of vaginal fluid from samples that are more forensically challenged.
Transdeseantes: de la heterosexualidad obligatoria al deseo lesbiano

Resumen de Transdeseantes : de la heterosexualidad obligatoria al deseo lesbiano Patricia Mateo Gallego En este articulo nos aproximamos a las teorias de cuatro autoras de referencia ineludible en el pensamiento feminista: Audre Lorde, Adrienne Rich, Monique Wittig y Judith Butler. Todas ellas, y en este trabajo por extension, se ocuparon de desentranar la logica que hace que unos grupos opriman a otros. Mas concretamente, la logica por la que la opresion de los hombres se ejerce sobre las mujeres. Nos referimos a la heterosexualidad obligatoria entendida como una institucion politica al servicio de un sujeto hegemonico que no desea perder su lugar privilegiado. Especialmente nos aproximaremos a posturas vitales desde las que desestabilizar este modo perverso de mantener a las mujeres en una posicion de otredad. This article approaches the theories of four main authors in feminist thought: Audre Lorde, Adrienne Rich, Monique Wittig and Judith Butler. All of them focused �as this article does� on the logic relations that makes some groups oppress others. Specifically, the logic that allows and perpetuates the tyranny exercised by men over women. We refer here to the compulsory heterosexuality that functions as a political institution by which an hegemonic subject preserves his privileged position. Moreover, we approach some personal positions from which it is possible to destabilize that established perverse way of keeping women in a position of otherness.
[Involvement of matrix metalloproteinase-2, -9, and tissue inhibitors of metalloproteinase-1, 2 in occurrence of the accrete placenta].

OBJECTIVE To investigate the roles of matrix metalloproteinase-9, -2 (MMP-9, 2), and tissue inhibitors of metalloproteinase-1, 2 (TIMP-1, 2) in pathogenesis of the accretio placenta. METHODS The women with the placenta accrete were recruited and the placenta (23) and deciduas tissues (9) after labor were obtained, and the placenta (28) and deciduas (11) from women without the placenta accreta were obtained as control to get, too. The expressions of MMP-9, -2, TIMP-1, 2 in the placental and decidual tissues were analyzed by real-time PCR. RESULTS mRNA expression of MMP-9 in the placenta accreta was (3.21 +/- 0.76) copies/microg total RNA, significantly higher (P < 0.05) than that of normal placenta [(3.84 +/- 0.24) copies/microg total RNA)]. MMP-9 transcription in the decidua accreta was (2.50 +/- 0.49) copies/microg total RNA, significantly higher (P < 0.05) than that of normal decidua [(3.81 +/- 0.66) copies/microg total RNA]. mRNA expression of TIMP-1 in normal placenta and placenta accreta was (5.91 +/- 0.56) and (5.92 +/- 0.46) copies/microg total RNA, respectively, with no significant difference between the two groups. mRNA expression of TIMP-1 in the accrete deciduas was (6.63 +/- 0.51) copies/microg total RNA, significantly lower (P < 0.05) than that of normal decidua (7.09 +/- 0.55) copies/microg. mRNA expression of MMP-2 in the accrete placenta was (4.55 +/- 1.13) copies/microg total RNA, significantly higher (P < 0.05) than that of normal placenta (5.53 +/- 0.59) copies/microg. mRNA expression of MMP-2 in the accrete decidua and normal decidua was (6.07 +/- 0.83) and (5.97 +/- 0.76) copies/microg total RNA, respectively, with no significant difference between the two groups. mRNA expression of TIMP-2 in the accrete placenta was (4.69 +/- 0.60) copies/microg total RNA, significantly higher (P < 0.05) than that of normal placenta (3.79 +/- 1.06) copies/microg. mRNA expression of TIMP-2 in the accrete decidua was (5.06 +/- 0.33) copies/microg total RNA, higher significantly (P < 0.05) than that of normal decidua (3.98 +/- 0.60) copies/microg. CONCLUSIONS The upregulation of MMP-9, MMP-2 in placenta and downregulation of TIMP-1 in decidua were involved in occurrence of the placental accreta, and the roles of TIMP-2 in occurrence of the placental accreta need to elucidated.
An adaptive neural network approach to the tracking control of micro aerial vehicles in constrained space

ABSTRACT This paper presents an adaptive neural network approach to the trajectory tracking control of micro aerial vehicles especially when they are flying in a limited indoor area. Differing from conventional controllers, the proposed controller employs the outer position loop to directly generate angular velocity commands in the presence of unknown aerodynamics and disturbances and then the fast inner loop to handle the angular rate control. Adaptive neural networks are deployed to estimate all the uncertain factors with the adaptation law derived from the Lyapunov function. To achieve a real-time performance, a norm estimation approach of ideal weights is designed to achieve a high bandwidth and lighten the burden of computation burden. Meanwhile, a barrier Lyapunov function is introduced to guarantee the constraint of vehicle positions as well as the validity of the neural network estimation. Simulations and practical flight tests are conducted to verify the feasibility and effectiveness of the proposed control strategy.
Effects of Streptococcal Cell Wall Fragments on Phagocytosis and Tissue Culture Cells

Group A streptococcal cell wall fragments inhibited phagocytosis of unrelated particles by rabbit polymorphonuclear leukocytes and inhibited the growth of rabbit kidney cells in vitro. Activity was associated with the mucopeptide moiety. Whole streptococci or the cytoplasmic fraction were less effective than cell wall fragments. The cell wall fragments of group D streptococci, Bacillus megaterium, and Escherichia coli were inactive. The inhibition of phagocytosis illustrates one way in which microbial components may influence the immune response. The toxicity for tissue cultures of rabbit kidney cell monolayers was greatest during the phase of active cell division. This appears to be a direct toxic effect of cell wall fragments on mammalian cells and may be related to the in vivo injury previously reported for streptococcal cell walls.
Fissured tongue responding to biologics during the treatment of psoriasis: the importance of detecting oral involvement of psoriasis

Recent studies have provided more evidence that psoriasis can give mucosal lesions, especially oral. Nonspecific lesions such as fissured tongue and geographic tongue are relatively frequent in patients suffering from psoriasis. We report a case of a patient presenting an important improvement of his fissured tongue paralleling the improvement of the cutaneous lesions after a 5‐month systemic therapy with infliximab. The authors think it would be important to consider possible oral lesions in patients suffering from psoriasis in normal practice and to evaluate them introducing specific clinical scales.
An architecture for secure mobile devices

Mobile devices such as smart phones have become one of the preferred means of accessing digital services, both for consuming and creating content. Unfortunately, securing such mobile devices is inherently difficult for a number of reasons. In this article, we review recent research results, systematically analyze the technical issues of securing mobile device platforms against different threats, and discuss a resulting and currently unsolved problem: How to create an end-to-end secure channel between the digital service e.g., a secure wallet application on an embedded smart card or an infrastructure service connected over wireless media and the user. Although the problem has been known for years and technical approaches start appearing in products, the user interaction aspects have remained unsolved. We discuss the reasons for this difficulty and suggest potential approaches to create human-verifiable secure communication with components or services within partially untrusted devices.

Stroke after Coronary Artery Surgery: A Single Center Report

Abstract Stroke or cerebrovascular accident (CVA) is a devastating complication of coronary surgery. In this report, the incidence, and correlates of CVA following isolated coronary artery bypass grafting (CABG) surgery were evaluated. Data were collected retrospectively. Between 2006 and 2009, 855 patients underwent isolated CABG surgery. CVA was defined as any new neurological deficit lasting more than 24 hours. Univariate and multivariate analyses were utilized as appropriate. The incidence of CVA was 1.4% (n = 12). Age, previous CVA, and emergency surgery were correlated by univariate analysis. Multivariate analysis revealed age, previous CVA, and chronic renal impairment as predictors of CVA. Ten (83.3%) of the 12 patients were diagnosed to have CVA in the first 24 hours. Length of hospital stay was 20.9 ± 20.34 days for CVA patients and 9.2 ± 5.17 days for non-CVA patients (p ≤ 0.001). There were 4 (33.3%) deaths in CVA group and 27 (3.2%) for non-CVA patients (p = 0.001). Postoperative CVA is a major contributor to mortality, prolonged hospitalization, and other adverse postoperative complications. Further studies are needed to develop better strategies to minimize the occurrence of CVA among patients undergoing CABG.
When Did Education Become a Civil Right? An Assessment of State Constitutional Provisions for Education, 1776-1900

This article provides a comprehensive review of provisions for public education found in American state constitutions from 1776 through 1900, chronologically tracing the pedigrees of the different formulations. It concludes that most provisions merely provided hortatory guidelines for legislatures, not judicially-enforceable rights to specific levels of taxpayer-supported education, and that even the few state constitutional provisions that appeared to impose certain mandates on the state legislatures were not interpreted in that fashion. Instead of a rights-based jurisprudence, equal protection analysis took over following adoption of the Fourteenth Amendment, leading courts to focus on the equality of funding inputs rather than any particular substantive guarantee.
Marine Natural Meroterpenes: Synthesis and Antiproliferative Activity

Meroterpenes are compounds of mixed biogenesis, isolated from plants, microorganisms and marine invertebrates. We have previously isolated and determined the structure for a series of meroterpenes extracted from the ascidian Aplidium aff. densum. Here, we demonstrate the chemical synthesis of three of them and their derivatives, and evaluate their biological activity on two bacterial strains, on sea urchin eggs, and on cancerous and healthy human cells.
Supporting Autonomy for Information Systems in a Changing Environment

Availability and scalability are important features of information systems. To gain this kind of requirements, we propose a distributed schema catalog in conjunction with appropriate development phases. The distributed schema catalog has to support distribution transparency including partitioning and replication to be exible for changes within organization structures. Additionally , phases of autonomy design have to appoint the adequate usage of distribution transparency aspects to enable execution autonomy by a minimum of replication. This paper only gives a brief overview concerning the development of distributed information systems based on object-oriented structures. 1 Motivation In the development of information systems, object-oriented speciication (e.g. Troll Jungclaus et al., 1995]) is useful for conceptually modeling of the universe of discourse. Viewing an information system as a collection of communicating objects is close to the intuitive perception of such systems on a conceptual level. A uniform lifecycle model of objects (or agents) covers the description of structural and behavioral aspects. Nowadays complex information systems (e.g. knowledge bases) are an integral part of organizations Fasnacht, 1993]. In order to be conducive for interconnecting departments, information systems have to be exible to accommodate for changes in organization structures. Mandatory features are distribution for decentralization support and scalability for modular system increase Simon, 1995]. Furtheron processing in parallel enables an important speedup Gray, 1995]. Thus, the task is to map the global conceptual model to computational reality as a distributed infrastructure. However the advantages of distribution are only usable by an adequate support of software. Object-oriented speciication consists of a global abstract description as conceptual model without non-functional requirements (e.g. distribution, persistence , exception handling). A distributed infrastructure consists of a set of interconnected loosely coupled nodes with own processors and disk-spaces. On whichìevel' distribution has to be combined with the conceptual model? A complex information system structure, which is described as conceptual entirety, is transparently distributed over several nodes. Important is a partial use of the information system, although not all nodes are available or reachable due to a site failure. How to achieve a maximum of node autonomy for a distributed system (C. J. Dates rst (of 12) rule for distributed database systems Date, 1990]) supported by the distributed schema catalog? Developing highly available information systems, we propose a distributed schema catalog in conjunction with autonomy design phases: Distributed schema catalog. In general, distributed database systems have to deal with a lot of e.g. data …
SRAM-based FPGAs: a structural test approach

This paper presents a structural approach for testing SRAM-based FPGAs taking into account the configurability of such flexible devices. The SRAM-based FPGA architecture is first discussed identifying the specific FPGA test problems as well as the FPGA test properties. The FPGA architecture is then conceptually divided into different architectural elements such as the logic cells, the interconnect cells and the RAM cells. For each architectural element appropriated fault models are proposed, and test configurations and test vectors are derived targeting the fault models under consideration. Taking into account the extremely long time required for SRAM-based FPGA re-configuration, the main objective of the proposed structural approach is the minimization of the number of test configurations.
Partial Loss of Ataxin-1 Function Contributes to Transcriptional Dysregulation in Spinocerebellar Ataxia Type 1 Pathogenesis

Spinocerebellar ataxia type 1 (SCA1) is a dominantly inherited neurodegenerative disease caused by expansion of a CAG repeat that encodes a polyglutamine tract in ATAXIN1 (ATXN1). Molecular and genetic data indicate that SCA1 is mainly caused by a gain-of-function mechanism. However, deletion of wild-type ATXN1 enhances SCA1 pathogenesis, whereas increased levels of an evolutionarily conserved paralog of ATXN1, Ataxin 1-Like, ameliorate it. These data suggest that a partial loss of ATXN1 function contributes to SCA1. To address this possibility, we set out to determine if the SCA1 disease model (Atxn1154Q/+ mice) and the loss of Atxn1 function model (Atxn1−/− mice) share molecular changes that could potentially contribute to SCA1 pathogenesis. To identify transcriptional changes that might result from loss of function of ATXN1 in SCA1, we performed gene expression microarray studies on cerebellar RNA from Atxn1−/− and Atxn1154Q/+ cerebella and uncovered shared gene expression changes. We further show that mild overexpression of Ataxin-1-Like rescues several of the molecular and behavioral defects in Atxn1 −/− mice. These results support a model in which Ataxin 1-Like overexpression represses SCA1 pathogenesis by compensating for a partial loss of function of Atxn1. Altogether, these data provide evidence that partial loss of Atxn1 function contributes to SCA1 pathogenesis and raise the possibility that loss-of-function mechanisms contribute to other dominantly inherited neurodegenerative diseases.
