Chemistry in disks II. Poor molecular content of the AB Aurigae disk

Aims. We study the molecular content and chemistry of a circumstellar disk surrounding the Herbig Ae star AB Aur at (sub-)millimeter wavelengths. Our aim is to reconstruct the chemical history and composition of the AB Aur disk and to compare it with disks around low-mass, cooler T Tauri stars. Methods: We observe the AB Aur disk with the IRAM Plateau de Bure Interferometer in the C- and D-configurations in rotational lines of CS, HCN, C2H, CH3OH, HCO^+, and CO isotopes. Using an iterative minimization technique, observed columns densities and abundances are derived. These values are further compared with results of an advanced chemical model that is based on a steady-state flared disk structure with a vertical temperature gradient, and gas-grain chemical network with surface reactions. Results: We firmly detect HCO+ in the 1-0 transition, tentatively detect HCN, and do not detect CS, C2H, and CH3OH. The observed HCO+ and 13CO column densities as well as the upper limits to the column densities of HCN, CS, C2H, and CH3OH are in good agreement with modeling results and those from previous studies. Conclusions: The AB Aur disk possesses more CO, but is less abundant in other molecular species compared to the DM Tau disk. This is primarily caused by intense UV irradiation from the central Herbig A0 star, which results in a hotter disk where CO freeze out does not occur and thus surface formation of complex CO-bearing molecules might be inhibited. Based on observations carried out with the IRAM Plateau de Bure Interferometer. IRAM is supported by INSU/CNRS (France), MPG (Germany) and IGN (Spain).
A National Survey of Gambling Problems in Canada

Objective: The 1990s saw widespread expansion of new forms of legalized gambling involving video lottery terminals (VLTs) in community settings (that is, in bars and restaurant lounges) and permanent casinos in several Canadian provinces. To date, there has never been a national survey of gambling problems with representative interprovincial data. Using a new survey, we sought to compare prevalence figures across the 10 Canadian provinces. Method: Using the Canadian Problem Gambling Index, we investigated the current 12-month prevalence of gambling problems in the Canadian Community Health Survey: Cycle 1.2—Mental Health and Well-Being, in which a random sample of 34 770 community-dwelling respondents aged 15 years and over were interviewed. The response rate was 77%. The data are representative at the provincial level and were compared with the availability of VLTs per 1000 population and with the presence of permanent casinos for each province. Results: Manitoba (2.9%) and Saskatchewan (also 2.9%) had the highest prevalence of gambling problems (specifically, moderate and severe problem levels combined). These 2 provinces had significantly higher levels than the 2 provinces with the lowest prevalence of gambling problems: Quebec (1.7%) and New Brunswick (1.5%). Conclusions: The 12-month prevalence of gambling problems in Canada was 2.0%, with interprovincial variability. The highest prevalence emerged in areas with high concentrations of VLTs in the community combined with permanent casinos. These findings support earlier predictions that the rapid and prolific expansion of new forms of legalized gambling in many regions of the country would be associated with a considerable public health cost.

From the results of this study it can be concluded that the generic science skills of students who use the guided inquiry learning model are better than the problem-based learning model, generic science skills students with high critical thinking skills are better than generic science skills students with low critical thinking skills, and there is no interaction between problem-based learning models and guided inquiry with the ability to think critically towards generic science skills of high school students.
Scaffolding Project Based Learning with the Rational Unified Process. Experience from 5 years of Student Projects in Software Engineering

The last years have seen a growing interest in Project Based Learning (PBL). Project Based Learning is associated with a constructivist approach, focusing on student driven learning in a collaborative setting. However, to provide real learning in a setting of higher education, the projects should be sufficiently complex and demanding. How can this be achieved without exposing the student to high risks of failure? The empirical background for this study is a two-semester course in software engineering at the Norwegian School of IT, with data collected over a period of 5 years with 1400 Bachelor students. The course is case based and is focused on designing and programming a complex solution. The pedagogy is based on the Rational Unified Process, focusing on iterative and incremental development. Building on Bruner’s concept of scaffolding, we propose that PBL may be successfully scaffolded by a formal software engineering method. In particular, the iterative and incremental structure of modern software engineering may serve as a basis for effective project learning. Our contribution is summarized with five types of scaffolding in PBL in a SW engineering context.

Performance and energy consumption analysis of a seismic application for three different architectures intended for oil and gas industry

In the most cases, seismic migration applications demand considerable computing throughput, since this feature denotes a need to apply complex models that are continuously run to evaluate drilling of petroleum wells. Given to the inherent computational complexity and the immense amount of processed data, High-Performance Computing (HPC) solutions can be attractive to perform this kind of application. Nowadays, low energy consumption has been highly desirable in high-performance processing when applied to large clusters that continuously run certain applications. Thereby, the use of an architecture that combines high performance and low energy consumption is desirable. This work describes an analysis in terms of performance, energy consumption and cost for three different architectures (Multicore, FPGA and GPGPU) intended to process a seismic application based on RTM (Reverse Time Migration) algorithm for an industrial application with this objective. Results indicate that the GPGPU architecture achieved the best performance in terms of energy consumption. When compared to the Multicore architecture, an about 15 times higher efficiency/Joule was observed. This architecture performed the RTM algorithm about 32 times faster when compared with the non-optimized implementation on CPU.
Rapid cytological analysis of endobronchial ultrasound-guided aspirates in sarcoidosis

Rapid on-site evaluation (ROSE) of endobronchial ultrasound-guided transbronchial needle aspirates (EBUS-TBNA) has not been compared to final detailed cytological analysis in patients with suspected sarcoidosis. To assess the diagnostic accuracy of EBUS-TBNA with ROSE in patients with suspected sarcoidosis, a prospective two-centre study performed EBUS-TBNA with ROSE of cellular material followed by transbronchial lung biopsy (TBLB) and endobronchial biopsy (EBB). The diagnostic accuracy of EBUS-TBNA with ROSE was compared to the final cytological assessment and to TBLB and EBB. Analysis confirmed 49 out of 60 cases of sarcoidosis. ROSE sensitivity was 87.8% (specificity 91%, positive predictive value 97.7%). ROSE slide interpretation in combination with the final fixed slide and cell block preparations had a sensitivity of 91.8% (specificity 100%, positive predictive value 100%). 67% of patients were confirmed as having sarcoidosis on TBLB and 29% on EBB. Interobserver agreement between cytotechnologists and pathologists was very good (&kgr;=0.91, 95% CI 0.80–1.0 and &kgr;=0.91, 95% CI 0.79–1.0, respectively). EBUS-TBNA with ROSE has high diagnostic accuracy and interobserver agreement and informs the bronchoscopist in theatre whether additional diagnostic procedures need to be undertaken. EBUS-TBNA with ROSE should therefore be considered as the first-line investigation of sarcoidosis. Rapid on-site evaluation of EBUS-TBNA should be first-line investigation in sarcoidosis http://ow.ly/nT9Mx
60-GHz Four-Element Phased-Array Transmit/Receive System-in-Package Using Phase Compensation Techniques in 65-nm Flip-Chip CMOS Process

AThe 60-GHz four-element phased-array transmit/receive (TX/RX) system-in-package antenna modules with phase-compensated techniques in 65-nm CMOS technology are presented. The design is based on the all-RF architecture with 4-bit RF switched LC phase shifters, phase compensated variable gain amplifier (VGA), 4:1 Wilkinson power combining/dividing network, variable-gain low-noise amplifier, power amplifier, 6-bit unary digital-to-analog converter, bias circuit, electrostatic discharge protection, and digital control interface (DCI). The 2 × 2 TX/RX phased arrays have been packaged with four antennas in low-temperature co-fired ceramic modules through flip-chip bonding and underfill process, and phased-array beam steering have been demonstrated. The entire beam-steering functions are digitally controllable, and individual registers are integrated at each front-end to enable beam steering through the DCI. The four-element TX array results in an output of 5 dBm per channel. The four-element RX array results in an average gain of 25 dB per channel. The four-element array consumes 400 mW in TX and 180 mW in RX and occupies an area of 3.74 mm2 in the TX integrated circuit (IC) and 4.18 mm2 in the RX IC. The beam-steering measurement results show acceptable agreement of the synthesized and measured array pattern.
Implementation of Extended Kalman Filter for Real-Time Noncontact ECG Signal Acquisition in Android-Based Mobile Monitoring System

Noncontact electrocardiogram (ECG) measurement using capacitive-coupled technique is a very reliable long-term noninvasive health-care remote monitoring system. It can be used continuously without interrupting the daily activities of the user and is one of the most promising developments in health-care technology. However, ECG signal is a very small electric signal. A robust system is needed to separate the clean ECG signal from noise in the measurement environment. Noise may come from many sources around the system, for example, bad contact between the sensor and body, common-mode electrical noise, movement artifacts, and triboelectric effect. Thus, in this paper, the extended Kalman filter (EKF) is applied to denoise a real-time ECG signal in capacitive-coupled sensors. The ECG signal becomes highly stable and noise-free by combining the common analog signal processing and the digital EKF in the processing step. Furthermore, to achieve ubiquitous monitoring, android-based application is developed to process the heart rate in a realtime ECG measurement.
Evolving Fuzzy Rule-based Classifiers

A novel approach to on-line classification based on fuzzy rules with an open/evolving structure is introduced in this paper. This classifier can start `from scratch', learning and adapting to the new data samples or from an initial rule-based classifier that can be updated based on the new information contained in the new samples. It is suitable for real-time applications such as classification streaming data, robotic applications, e.g., target and landmark recognition, real-time machine health monitoring and prognostics, fault detection and diagnostics, etc. Each prototype is a data sample that represents the focal point of a fuzzy rule per class and is selected based on the data density by an incremental and evolving procedure. This approach is transparent, linguistically interpretable, and applicable to both fully unsupervised and partially supervised learning. It has been validated by two well known benchmark problems and by real-life data in a parallel paper. The contributions of this paper are: i) introduction of the concept of evolving (open structure) classification (eClass) of streaming data; ii) experiments with well known benchmark classification problems (Iris and wine reproduction data sets)
A Dynamic Panel Data Approach to the Forecasting of the GDP of German Länder

Abstract In this paper, we make multi-step forecasts of the annual growth rates of the real GDP for each of the 16 German Länder simultaneously. We apply dynamic panel models accounting for spatial dependence between regional GDP. We find that both pooling and accounting for spatial effects help to improve the forecast performance substantially. We demonstrate that the effect of accounting for spatial dependence is more pronounced for longer forecasting horizons (the forecast accuracy gain is about 9% for a 1-year horizon and exceeds 40% for a 5-year horizon). We recommend incorporating a spatial dependence structure into regional forecasting models, especially when long-term forecasts are made.
MAAI: Media analytics for actionable intelligence

Government agencies, corporations, and police departments are plagued by information overload. The inability of fully analyze fragments of data scattered across the organizations reduces productivity, and more and more of these fragments are being gathered every day thanks to tools like the Internet and digital audio/video recorders. However, since much of this information is stored in computer systems and networks, it is possible to develop tools that will automatically analyze, assemble and associate the fragments so that precious human resources can focus on the analysis and interpretation of just those fragments that may contain valuable insight. Media analytics for actionable intelligence (MAAI) is a combination of automatic, semi-automatic and manual tools which provide three basic levels of analysis: automatic services, manual feedback, and higher level mining (e.g. timeline, social network, hypothesis generation) which allow investigators/analysts to act more efficiently and accurately.
Narcissism, Collective Efficacy, and Satisfaction in Self-Managed Teams: The Moderating Role of Team Goal Orientation

The current study examined: (a) the association of narcissism with team member perceptions of collective efficacy and satisfaction, and (b) a multilevel framework in which the associations of narcissism with collective efficacy and satisfaction were dependent on team level goal-orientation. To accomplish our goal, we gathered data from 206 students who formed 35 self-managed teams. Narcissism, satisfaction, and perceptions of collective efficacy were examined at the individual level. Goal orientations were examined at the team level. Multilevel models using hierarchical linear modeling (HLM) were employed to analyze these data. Results demonstrated a significant main effect of narcissism for collective efficacy, but not for satisfaction. Additionally, team goal orientation moderated the narcissism–collective efficacy, and narcissism–satisfaction relationships such that narcissist team members reported (a) the highest levels of collective efficacy in teams with high levels of performance-prove goals, and (b) lowest levels of satisfaction in teams with low levels of performance-avoidance goals. Implications of these findings are discussed.
Characterizing molecular adaptation: a hierarchical approach to assess the selective influence of amino acid properties

MOTIVATION A number of methods for detecting positive selection in protein coding DNA sequences are based on whether each site/region has a non-synonymous to synonymous substitution rates ratio ω greater than one. However, a site/region may show a relatively large number of non-synonymous mutations that conserve a particular property. Recent methods have proposed to consider as evidence for molecular adaptations how conserving, or radically different, non-synonymous mutations are with respect to some key amino acid properties. While such methods have been useful in providing a qualitative assessment of molecular adaptation, they rely on independent statistical analyses for each amino acid property and typically do not properly adjust for multiple comparisons when selection needs to be assessed at several sites. RESULTS We consider a Bayesian hierarchical model that allows us to jointly determine if a set of amino acid properties are being conserved or radically changed while simultaneously adjusting for multiple comparisons at the codon level. We illustrate how this model can be used to characterize molecular adaptation in two datasets: an alignment from six class I alleles of the human major histocompatibility complex and a sperm lysin alignment from 25 abalone species. We compare the results obtained with the proposed hierarchical models to those obtained with alternative methods. Our analyses indicate that a more complete quantitative and qualitative characterization of molecular adaptation is achieved by taking into account changes in amino acid properties. AVAILABILITY The R code for implementing the hierarchical models is freely available at http://www.ams. ucsc.edu/∼raquel/software/.
Efficacy of two iso-propanol-based skin antiseptics applied to human skin with many sebaceous glands for 2 and 10 minutes

Background: Recent research suggests that specific ethanol-based skin antiseptics exhibit their efficacy on the resident skin flora of the forehead in only 2.5 minutes. We have now looked at the efficacy of two skin antiseptics based on 63% (w/w) propan-2-ol (iso-propanol) and applied for 10 and 2 minutes on skin with a high density of sebaceous glands. Methods: Each experiment was performed in a reference-controlled cross-over design with at least 20 participants. Application of isopropanol (70%, v/v) for 10 minutes to the forehead served as the reference treatment. Pre-values and post-values (immediately after the application and after 30 min) were obtained by swabbing a marked area of 5 cm2 for about 10 s. Swabs were vortexed in tryptic soy broth containing valid neutralizing agents. After serial dilution aliquots were spread on tryptic soy agar. Colonies were counted after incubation of plates at 36°C for 48 h. The mean log10 reduction of bacteria was calculated. The Wilcoxon matched-pairs signed-ranks test was used for a comparison of treatments. Results: Skin antiseptic A applied for 10 min (one experiment) was equally effective to the reference treatment. When applied for 2 min (two experiments) it was still equally effective to the reference treatment immediately after application (e.g. 1.6 versus 1.4 log10 reduction) and after 30 min (1.7 versus 1.4 log10 reduction). Skin antiseptic B applied for 10 and 2 min (one experiment each) was also equally effective to the reference treatment both immediately after application and after 30 min. Conclusions: The clear and coloured skin antiseptics applied for 2 min on the skin of the forehead fulfilled the national efficacy requirements for skin antisepsis. The shorter application time on skin with a high density of sebaceous glands will allow acting more efficiently in clinical practice.
Recommendations for Monitoring and Evaluation of In-Patient Computer-based Provider Order Entry Systems: Results of a Delphi Survey

A survey of 20 clinical informaticists with experience in implementing Computer-based Provider Order Entry (CPOE) systems revealed the lack of easily accessible measurements of success. Using a Delphi approach, the authors, together with a group of CPOE experts, selected eight key CPOE-related measures to assess system availability, use, benefits, and e-Iatrogenesis. We suggest collecting these measures on a widespread/national basis would be wise stewardship and result in tighter feedback about both clinician workflow and patient safety. Establishing reliable benchmarks against which new implementations and existing systems can be compared will enhance organizations' ability to effectively manage and hence to realize the full benefits of their CPOE implementations.
EFFICIENT RECONSTRUCTION OF NURBS SURFACES FOR SHAPE ANALYSIS AND SURFACE INSPECTION

We present a new approach for the fast visualization and evaluation of large point clouds derived from different structured light 3D-scanners. By using the underlying measuring principle, we generate regular quadrilateral meshes in nearly real-time. These meshes are additionally used for a partial NURBS approximation. Based on the derived parameterized surfaces we are able to calculate and measure higher degree surface features, e.g. curvature and its direction. Finally, we evaluate the efficiency and feasibility of our approaches at the example of a variety of different point clouds. a) b) c) Figure 1: Illustration of the generated mesh (a), together with the finally shaded model (b) and the computed Gaussian curvature on the object surface (c).
A new simplified multilevel inverter topology for grid-connected application

Multilevel inverter performance is high compared to the conventional two level inverters due to their reduced harmonic distortion, lower electromagnetic interference. However the main drawback of multilevel inverter is increased number of switches, complex pulse width modulation control and balancing of capacitor voltages. This paper proposes a single phase seven level inverter for grid connected system. The proposed inverter topology consists of fewer components with low complexity gate drives and control signals. An LC filter is used to limit the switching current ripple by providing high attenuation of harmonic and high dynamic performance. This paper also presents the most relevant control and modulation methods by a new reference/carrier based PWM scheme employing three similar reference signals with an offset of magnitude equal to the amplitude of the carrier signal. The entire system is numerically simulated using MATLAB/SIMULINK and the simulation results are presented.
