Left Ventricular Longitudinal Function Predicts Life-Threatening Ventricular Arrhythmia and Death in Adults With Repaired Tetralogy of Fallot

Background— Sudden cardiac death and life-threatening ventricular arrhythmia remain a concern in adult patients with repaired tetralogy of Fallot. Longitudinal left ventricular (LV) function is sensitive in detecting early myocardial damage and may have prognostic implications in this setting. Methods and Results— We included 413 tetralogy of Fallot patients (age, 36±13 years; QRS duration, 148±27 milliseconds; LV ejection fraction, 55±10%). A composite end point of sudden cardiac death/life-threatening ventricular arrhythmia (sustained ventricular tachycardia, resuscitated sudden cardiac death, or appropriate implantable cardioverter-defibrillator discharge) was used. During a median follow-up of 2.9 years, 5 patients died suddenly, 9 had documented sustained ventricular tachycardia, and another 5 had appropriate implantable cardioverter-defibrillator shocks. On univariate Cox analysis, QRS duration (hazard ratio [HR], 1.02 per 1 ms; P=0.046), right atrial area (HR, 1.05 per 1 cm2; P=0.02), right ventricular fractional area change (HR, 0.94 per 1%; P=0.02), right ventricular outflow tract diameter (HR, 1.08 per 1 mm; P=0.01), mitral annular plane systolic excursion (HR, 0.84 per 1 mm; P=0.03), and LV global longitudinal 2-dimensional strain (HR, 0.87 per 1%; P=0.03) were related to the combined end point. On bivariable analysis, mitral annular plane systolic excursion and LV global longitudinal 2-dimensional strain were related to outcome independently of QRS duration (P=0.002 and P=0.01, respectively). In addition, a combination of echocardiographic variables, including right atrial area, right ventricular fractional area change, and LV global longitudinal 2-dimensional strain or mitral annular plane systolic excursion, was also found to be significantly related to outcome (P<0.001; c statistic, 0.70). Conclusions— LV longitudinal dysfunction was associated with greater risk of sudden cardiac death/life-threatening ventricular arrhythmias. In combination with echocardiographic right heart variables, also available from routine echocardiography, these measures provide important outcome information and should be considered a useful adjunct to established markers such as QRS duration in the estimation of prognosis in this challenging population.
Why Do They Want to Become Teachers? A Study on Prospective Teachers’ Motivation to Teach in Hong Kong

Teaching as an occupation in Hong Kong differs significantly from the western context from which most researches on teaching motivation originate. Through in-depth interviews with 38 graduands of a teacher-preparation programme, beginning teachers’ motivations for choosing teaching were explored using grounded theory methods. Respondents’ motivations coalesce into two categories, “teaching as a safe haven”, and “internal satisfaction”. Participants were conceptualized as falling into two groups: one group was motivated exclusively by “internal satisfaction”, the other saw “teaching as a safe haven” but at the same time also appreciated teaching’s internal satisfaction.
Information Acquisition and Decisions Under Risk and Ambiguity

This paper experimentally investigates individual information acquisition and decisions in ambiguous situations in which the degree of ambiguity can endogenously and individually be decreased by the subjects. In particular, I analyze how risk aversion, ambiguity attitude and personality traits are related to an individual's information acquisition prior to a decision and to the decision itself based on this information. I focus on urn decisions and conduct treatments that consider the loss and gain domain separately and that vary the amount of available information and the probabilistic structure. I find that risk and ambiguity aversion affect the information acquisition but are less influential for the decisions between two ambiguous urns according to several heuristics. In contrast, personality traits and an individual's primary decision type turn out to have an impact on both information acquisition and decisions. I observe that under this study's presentation format the reflection effect is reversed for negative and positive payoffs in low probability treatments compared to corresponding results under a descriptive presentation format.
Incorporating Negative Information in Process Discovery – Technical Report –

The discovery of a formal process model from event logs describing real process executions is a challenging problem that has been studied from several angles. Most of the contributions consider the extraction of a model as a semi-supervised problem where only positive information is available. In this paper we present a fresh look at process discovery where also negative information can be taken into account. This feature may be crucial for deriving process models which are not only simple, fitting and precise, but also good on generalizing the right behavior underlying an event log. The technique is based on numerical abstract domains and Satisfiability Modulo Theories (SMT), and can be combined with any process discovery technique. As an example, we show in detail how to supervise a recent technique that uses numerical abstract domains. Experiments performed in our prototype implementation show the effectiveness of the techniques and the ability to improve the results produced by selected discovery techniques.
Energy consumption in reconfigurable mpsoc architecture: Two-level caches optimization oriented approach

In order to meet the ever-increasing computing requirement in embedded market, multiprocessor chips were proposed as the best way out. In this work we investigate the estimation of the energy consumption in embedded MPSoC system. One of the efficient solutions to reduce the energy consumption is to reconfigure the caches memories. This approach was applied for one cache level/one processor architecture. The main contribution of this paper is to explore two level data cache (L1/L2) multiprocessor architecture by estimating the energy consumption. Using a simulation platform (Multi2Simj, we first built a multiprocessor architecture, and then we propose a new modified CPACT algorithm that tunes the two-level caches memory hierarchy (L1 & L2). The caches tuning approach is based on three parameters: cache size, line size, and associativity. In this approach, and in order to find the best cache configuration, the software application is divided into several intervals and we generate automatically the best cache configuration for each interval of the application. Finally, the approach is validated using a set of open source benchmarks, Spec2006, Splash-2 and MediaBench and we discuss the performance in terms of speedup and energy reduction.
Educación e Inmigración en España

La problematica de la inmigracion, como otros temas similares, a pesar de ser un fenomeno de gran importancia (sin integracion no es posible la paz social y la seguridad ciudadana) ha irrumpido en el contexto espanol, sin la precisa planificacion. La realidad es que nuestro pais constituye un destino importante para la inmigracion. Por tanto, se precisa una adecuada preparacion de toda la poblacion —cambio de actitudes, fundamentalmente— y la existencia de infraestructuras para abordar las necesidades que aparecen en la sociedad espanola, ante el imparable fenomeno que se esta produciendo. La inmigracion hace estallar la evidencia de la diversidad. La aparicion de los inmigrantes, no solo ha suscitado un problema nuevo, sino que nos obliga a percibir y reformular otros viejos. En suma, las diferencias reclaman, por un lado, su reconocimiento y valorizacion, desde la institucion y la cultura escolares; por otro, su incorporacion a ellas. Supone algo mas que la tolerancia, pues no se trata solo de no perseguirlas, sino tambien de admitir que contienen elementos de valor, de los que la propia cultura dominante y la escolar pueden beneficiarse. Ademas, implica una traduccion de los contenidos y la practica educativa, pero para todos y todas. La diversidad, considerada como valor positivo, implica orientar la educacion hacia los principios de igualdad, justicia y libertad, por lo que resulta imprescindible un compromiso permanente con las culturas y grupos minoritarios. Se incluye una investigacion sobre las actitudes del profesorado ante la interculturalidad, que nos permite reflexionar sobre la situacion actual y la necesidad de ofrecer un marco educativo adecuado para posibilitar una autentica atencion a la diversidad, sin ningun tipo de discriminacion.
Identifying high-cardinality hosts from network-wide traffic measurements

Host cardinality is defined as the number of distinct peers that a host communicates with in the network. There have been several algorithms proposed to monitor network traffic and identify high-cardinality hosts at a centralized network operation center (NOC). Due to massive amounts of data and limitations on transforming and processing them at the NOC, it is desirable to design mergeable and reversible data structures summarizing traffic measurements in a distributed network monitoring system. A mergeable data structure summarizes traffic measurements at each local monitor, and these summaries from different monitors can be merged at the NOC, while preserving the error guarantee without increasing space. A reversible data structure can report interested (high-cardinality) hosts efficiently using compressed information without querying every single host in the network. In this paper, we propose a new data streaming algorithm to identify high-cardinality hosts over the network-wide traffic measurements. Our algorithm introduces a new mergeable and reversible data structure for the distributed network monitoring system, which is designed by Noisy Group Testing. We have theoretically analyzed our algorithm and evaluated it against both synthetic and real-world data sets.

Here, we report the draft genome sequence of strain IDO, which may provide useful genetic information on indole metabolism and polyhydroxyalkanoate production.
An algorithm for automatic detection of drowsiness for use in wearable EEG systems

Lack of proper restorative sleep can induce sleepiness at odd hours making a person drowsy. This onset of drowsiness can be detrimental for the individual in a number of ways if it happens at an unwanted time. For example, drowsiness while driving a vehicle or operating heavy machinery poses a threat to the safety and wellbeing of individuals as well as those around them. Timely detection of drowsiness can prevent the occurrence of unfortunate accidents thereby improving road and work environment safety. In this paper, by analyzing the electroencephalographic (EEG) signals of human subjects in the frequency domain, several features across different EEG channels are explored. Of these, three features are identified to have a strong correlation with drowsiness. A weighted sum of these defining features, extracted from a single EEG channel, is then used with a simple classifier to automatically separate the state of wakefulness from drowsiness. The proposed algorithm resulted in drowsiness detection sensitivity of 85% and specificity of 93%.

Maximum-Likelihood Estimation for Indicator Dilution Analysis

Indicator-dilution methods are widely used by many medical imaging techniques and by dye-, lithium-, and thermodilution measurements. The measured indicator dilution curves are typically fitted by a mathematical model to estimate the hemodynamic parameters of interest. This paper presents a new maximum-likelihood algorithm for parameter estimation, where indicator dilution curves are considered as the histogram of underlying transit-time distribution. Apart from a general description of the algorithm, semianalytical solutions are provided for three well-known indicator dilution models. An adaptation of the algorithm is also introduced to cope with indicator recirculation. In simulations as well as in experimental data obtained by dynamic contrast-enhanced ultrasound imaging, the proposed algorithm shows a superior parameter estimation accuracy over nonlinear least-squares regression. The feasibility of the algorithm for use in vivo is evaluated using dynamic contrast-enhanced ultrasound recordings obtained with the purpose of prostate cancer detection. The proposed algorithm shows an improved ability (increase in receiver-operating characteristic curve area of up to 0.13) with respect to existing methods to differentiate between healthy tissue and cancer.
Adjuvant docetaxel, cisplatin and 5-fluorouracil (TPF) in locally advanced squamous cell carcinoma of the head and neck.

BACKGROUND In this phase II study, the efficacy and toxicity of a triple chemotherapy with docetaxel, cisplatin and 5- Fluorouracil (TPF) was evaluated in the adjuvant therapy of locoregionally advanced cancer of the head and neck. This represented the first use of polychemotherapy as single adjuvant therapy after surgery. PATIENTS AND METHODS Twenty patients with stage II-IV (UICC) squamous cell carcinoma of the head and neck (SCCHN) were treated by surgery of the primary and the regional lymph nodes. Four weeks after surgery, all patients received polychemotherapy consisting of docetaxel 75 mg/m2 day 1, cisplatin 100 mg/m2 day 1 and 5- Fluorouracil (5- FU) 1000 mg/m2 days 1 through 4 (total dose 4000 mg/m2), on days 1, 22 and 43 for a maximum of 3 cycles. The performance status of all patients at the beginning of the chemotherapy was 0-1 according to the Eastern Cooperative Oncology Group (ECOG). RESULTS Fifty-eight cycles were administered to the 20 patients. The major acute toxicities were mucositis (2 patients) and febrile neutropenia (4 patients). One patient dropped out after the first cycle because of severe mucositis. After a median follow-up of 16.5 months (range, 1-41 months), the median time to progression was 20 months (range, 16-22 months). The estimated overall survival according to Kaplan-Meier at the median time of follow-up was 90%. No distant metastases were detectable after the adjuvant chemotherapy with TPF in locally advanced SCCHN, neither were late effects observed. CONCLUSION TPF was tolerated, with an acceptable toxicity profile, in patients with a good performance status. The preliminary results appear to justify further investigations to evaluate the efficacy of this modality in the adjuvant setting.
cis-Acting Determinants of Heterochromatin Formation on Drosophila melanogaster Chromosome Four

ABSTRACT The heterochromatic domains of Drosophila melanogaster (pericentric heterochromatin, telomeres, and the fourth chromosome) are characterized by histone hypoacetylation, high levels of histone H3 methylated on lysine 9 (H3-mK9), and association with heterochromatin protein 1 (HP1). While the specific interaction of HP1 with both H3-mK9 and histone methyltransferases suggests a mechanism for the maintenance of heterochromatin, it leaves open the question of how heterochromatin formation is targeted to specific domains. Expression characteristics of reporter transgenes inserted at different sites in the fourth chromosome define a minimum of three euchromatic and three heterochromatic domains, interspersed. Here we searched for cis-acting DNA sequence determinants that specify heterochromatic domains. Genetic screens for a switch in phenotype demonstrate that local deletions or duplications of 5 to 80 kb of DNA flanking a transposon reporter can lead to the loss or acquisition of variegation, pointing to short-range cis-acting determinants for silencing. This silencing is dependent on HP1. A switch in transgene expression correlates with a switch in chromatin structure, judged by nuclease accessibility. Mapping data implicate the 1360 transposon as a target for heterochromatin formation. We propose that heterochromatin formation is initiated at dispersed repetitive elements along the fourth chromosome and spreads for ∼10 kb or until encountering competition from a euchromatic determinant.
The relationship of differential loci with perceived quality and behavioral intentions

This paper suggests that he/she whom the customer holds most responsible for a service experience may influence which service quality dimensions take precedence in customer satisfaction, word‐of‐mouth intentions, and repurchase intentions. Results indicate that, when consumers find the contact employee more responsible for the experience, what is delivered is most important to evaluations of service quality, satisfaction, and behavioral intentions. When management is thought to be more responsible, how the service is delivered is essential to consumers’ evaluations. When responsibility is perceived as shared between the contact employee and management, the physical environment may play a larger role in influencing consumers’ satisfaction with the service experience.
Defining the Bounding Edges of a SynthaVision Solid Model

A computer software package is described, whose function is to provide an interface from a solid geometric modeler to a more conventional 3D wireframe system. Specifically, the conversion of a SynthaVision solid model to an edge-vertex data structure is discussed. The paper describes, qualitatively, the approach to solid modeling used in SynthaVision, a geometry translator that outputs an "edge file" containing the bounding edges of the model, and a view generator that processes the edge file to produce line drawings.
Fractal analysis of geochemical data in prospecting for oil

The paper describes possible ways of interpreting a complex of geochemical anomalies used in prospecting for oil and connected with the analysis of gas survey. The use of fractal features of power spectra and gas diffusion peculiarities in the fractal medium has allowed constructing a linearized model of spatial hydrocarbon migration. The proposed procedure of the fractal analysis of geochemical data is tested on a number of practical examples.
DISCRETIZATION OF SINGULAR SYSTEMS AND ERROR ESTIMATION N

This paper proposes a discretization technique of a descriptor differential system. The methodology used is both triangular first order hold (interpolating FOH) discretization and zero order hold (ZOH) for the input function. Upper bounds for the error between the continuous and discrete time solution are produced for both discretization methods and are shown to be better than any other existing method in the literature.

Columbia MVSO Image Sentiment Dataset

The Multilingual Visual Sentiment Ontology (MVSO) consists of 15,600 concepts in 12 different languages that are strongly related to emotions and sentiments expressed in images. These concepts are defined in the form of Adjective-Noun Pair (ANP), which are crawled and discovered from online image forum Flickr. In this work, we used Amazon Mechanical Turk as a crowd-sourcing platform to collect human judgments on sentiments expressed in images that are uniformly sampled over 3,911 English ANPs extracted from a tag-restricted subset of MVSO. Our goal is to use the dataset as a benchmark for the evaluation of systems that automatically predict sentiments in images or ANPs.
