Identifying Influential Rumor Spreader in Social Network

It is of great significance to identify influential rumor spreaders for preventing and controlling the rumor propagation. In this paper, on four real social networks, based on the classical rumor model and combining one-to-many modes of propagation, we investigate the rumor propagation by Monte Carlo simulations when the spreading rate is small. Firstly, we layer the network nodes according to network characteristics. If the assortative coefficient is positive, we layer the network nodes by the degree centrality and the nodes with large degree are in high layers. If the assortative coefficient is negative, we layer the network nodes by the K-Shell method and the nodes with large Ks value are in high layers. Then the performance of nodes in different layers as origination of rumors and as informed nodes is investigated. We find that the propagation size is larger and the peak prevalence of the rumor is reached in a shorter time when the nodes in higher layers act as origination. Moreover, when the nodes in higher layer are not the origination of the rumor, they are more likely to be informed and they are informed more faster, and they terminate propagation faster. That is, their attendance is more beneficial to propagation size, peak prevalence, and the arrival time of peak prevalence. The conclusion can provide powerful theoretical support for controlling rumor propagation or enhancing information transmission.
Risk Factors for Malignancy of Branch-Duct Intraductal Papillary Mucinous Neoplasms: A Critical Evaluation of the Fukuoka Guidelines With a Systematic Review and Meta-analysis.

OBJECTIVES This study aimed to evaluate the accuracy of the risk factors proposed by Fukuoka guidelines in detecting malignancy of branch-duct intraductal papillary mucinous neoplasms. METHOD Diagnostic meta-analysis of cohort studies. A systematic literature search was conducted using MEDLINE, the Cochrane Library, Scopus, and the ISI-Web of Science databases to identify all studies published up to 2014. RESULTS Twenty-five studies (2025 patients) were suitable for the meta-analysis. The "high risk stigmata" showed the highest pooled diagnostic odds ratio (jaundice, 6.3; positive citology, 5.5; mural nodules, 4.8) together with 2 "worrisome features" (thickened/enhancing walls, 4.2; duct dilatation, 4.0) and 1 "other parameters" (carbohydrate antigen 19-9 serum levels, 4.6). CONCLUSIONS An "ideal risk factor" capable of recognizing all malignant branch-duct intraductal papillary mucinous neoplasms was not identified and some "dismal areas" remain. However, "high risk stigmata" were strongly related to malignancy, mainly enhancing mural nodules. Among the "worrisome features," duct dilatation and thickened/enhancing walls were underestimated, and their diagnostic performance was similar to those of "high risk stigmata. " The carbohydrate antigen 19-9 serum level should be added to the Fukuoka algorithm because this value could help in carrying out correct management.
Predictive Current Control Strategy With Imposed Load Current Spectrum

This paper presents a modified predictive current control strategy which allows one to have control over the spectrum of the load current. The proposed method uses a model of the system to predict the behavior of the current for each possible voltage vector generated by the inverter. For that purpose, at each sampling interval, signal predictions are evaluated using a cost function that quantifies the desired system behavior. The cost function used in this work evaluates the filtered error of the load currents. The inclusion of a filter for the load error allows one to manipulate current spectra. Thus, by designing this filter appropriately, the load spectrum can be shaped. The performance of the proposed control strategy is verified by simulation and experimental results.
Study on Strength Characteristics Improvement of Polyethylene Modified Bituminous Concrete Mixes

The present study shows an investigation on improvement of bituminous binder and its mixes using modified binders with different percentage (1% to 7%) of domestic waste polyethylene (PE). The temperature susceptibility and penetration index (PI) of the modified binders were calculated. It is observed that PI value of modified binder is found higher than unmodified binder. The strength characteristics in terms of Marshall Stability and moisture susceptibility expressed in terms of indirect tensile strength ratio (ITSR) of bituminous concrete were determined in the present study. Marshall stability of the bituminous mixture containing 3% PE increased by 34.2% as compare to mixture containing unmodified binder. The addition of 3% PE to neat bitumen, results in an increase of 20% in indirect tensile strength ratio. Using PE modified binder in bituminous concrete mixes increases stability, indirect tensile strength which turn in provide better resistance against permanent deformation.
Evaluation of a novel, short polyA signal from the Bombyx mori bidensovirus.

Bombyx mori bidensovirus (BmBDV) is the only virus which belongs to the new Bidnaviridae family established by the International Committee on Taxonomy of Viruses in 2012. The genes encoding the major capsid protein and DNA polymerase (pPolB) overlap partially at their 3′ untranslated regions, forming an extremely short, dual-function polyadenylation signal/stop codon (BmBDV polyA) to complete post-transcriptional modifications and terminate protein expression. Nevertheless, the functionality and usefulness of this signal regarding foreign genes remain unknown. To determine the effect of the BmBDV polyA on gene expression, the expression of the green fluorescent protein and firefly luciferase was evaluated with the BmBDV polyA, compared with the much larger SV40 polyA, under the control of the p5 or ie1 promoter. Fluorescence microscopy and dual luciferase assay both revealed enhanced expression of these proteins in the presence of the BmBDV polyA, meanwhile real-time qPCR also showed increased mRNA levels. Therefore, we conclude that the BmBDV polyA is a promising, characteristic polyA signal from an insect virus, and that it can promote gene expression at either the mRNA or protein levels. Additionally, this study also suggests that the BmBDV polyA potentially alleviates restrictions associated with the size of inserted fragments during constructing recombinant viruses.
Designing a Vertical / Horizontal AUV for Deep Ocean Sampling

Faculty and students at the URI Dept. of Ocean Engineering have conceived of a new class of AUV for deep sea profiling and sampling called a Mini Ocean Elevator (or MiniOE). The MiniOE is intended to operate as both a vertical and a horizontal AUV on the same mission, beginning its mission as a vertical profiler and then converting to a horizontal AUV for sampling prior to homing on an acoustic beacon at the surface. Such a vehicle has tremendous potential for ocean research while presenting unique challenges for stability and control. Horizontal AUVs typically achieve stability against roll and pitch through significant mass below the center of buoyancy along with tail fins. For a vertical vehicle this mass-ballast displacement must be in an orthogonal direction along the longitudinal axis to achieve stability in pitch and yaw, forsaking roll stability. Designing a cigar shaped AUV capable of both horizontal and vertical stability represents an unusual challenge. This paper describes the design work and testing involved in developing a stable vertical AUV that will later be equipped to convert itself to a stable horizontal AUV. This design effort used a balanced combination of physical experimentation and computer simulation to provide detailed information about how different configurations of an autonomous underwater vehicle (AUV) might affect its stability, and thus the controllability, while using conventional hardware and software resources.
Deep Sensor Fusion Between 2D Laser Scanner and IMU for Mobile Robot Localization

Multi-sensor fusion plays a key role in 2D laser-based robot location and navigation. Although it has achieved great success, there are still some challenges, e.g., being fragile when having a large angular rotation. In this paper, we present a deep learning-based approach to localizing a mobile robot using a 2D laser and an inertial measurement unit. A novel recurrent convolutional neural network (RCNN)-based architecture is developed to fuse laser and inertial data for scan-to-scan pose estimation. A scan-to-submap optimization is also introduced to optimize the poses estimated by the RCNN for enhanced robustness and accuracy. Extensive experiments have been conducted in both simulation and practice with a real mobile robot, verifying the effectiveness of the proposed deep sensor fusion system.
Determination of Minerals, Total Phenolic Content, Flavonoids, Antioxidants and Antimicrobial Activities of Ethanolic Extract of Sweet Lupinus angustifolius of Palestine

Aims: To establish the most suitable extraction method for sweet lupine seeds and to determine minerals, phenolic content, flavonoids, antioxidant activity and antimicrobial activities. Study Design: Known and standard experimental procedures are employed. Place and Duration of Study: Department of Chemistry, Bethlehem University- Palestine, from January 2019 to March 2019. Methodology: Seeds were ground and extracted by Soxhlet extractor using ethanol with different percentages (50%, 60%, 70%, 80% and 95%). Sodium, potassium and ferrous ion content were determined. Resistance to bacteria was performed against Escherichia coli and Staphylococcus aureus, while antioxidant activity was determined by FRAP method. Two types of flavonoids were measured: Flavonones and dihydroflavonols via the reaction with 2,4-dinitrophenylhydrazine. Phenolics were determined by the Folin-Ciocalteu method. Results: 50% ethanol resulted in the highest extract residue (18.6%) while 70% and 60% showed the lowest content (10.0% for both). 80% ethanol extracted sample showed the highest content for sodium (56.51 mg Na/g extract), while 60% and 50% ethanol extracts showed the highest content of potassium (2.25 and 2.33 mg K/g extract, respectively). The maximum concentration of ferrous ion was obtained with 70% ethanol (6.854 mg Fe+2/g extract). 95% ethanolic extract showed the highest antioxidant activity (20.24 mg FeSO4/g extract). Similar results were obtained for total phenolic content and flavonoids: 24.60 mg gallic acid/g extract for phenolics and 116.02 mg rutin/g extract for flavonoids. Extracts showed no bacterial activity against both types of bacteria used. Conclusion: 95% ethanol extracted samples showed the highest antioxidant activity and the highest flavonoids and phenolic content. Sweet lupine extract did not perform any antimicrobial activity against both Gram positive and Gram negative bacteria.
The use of accelerated full-wave modeling to analyze power island coupling in a HyperBGA SCM

Presented here are results and recommendations for reducing coupling between adjacent power islands based on full-wave simulations of a HyperBGA SCM (single-chip module). These simulations highlight the use of IBM's internally developed, accelerated full-wave solver based on the pre-corrected FFT approach. Speedups of 60/spl times/ and memory reductions of 12/spl times/ are shown for real engineering problems, as compared to direct integral equation solutions.
What Is the Optimal Dose and Schedule for Dasatinib in Chronic Myeloid Leukemia: Two Case Reports and Review of the Literature

Efficacy and safety of dasatinib in chronic phase (CP) chronic myelogenous leukemia (CML) patients has been well established. Initially approved dose and schedule of 70 mg twice daily has been changed to 100 mg once daily after demonstration of the same efficacy with less toxicity. Some patients require significant dose reductions to enable continued treatment with dasatinib. Even at a dose of 80 mg once daily, several patients may require further dose reductions due to substantial toxicity while maintaining good control of their disease. We report two CP-CML patients achieving and maintaining major molecular responses while on very low doses of dasatinib, ultimately achieving undetectable levels of BCR-ABL fusion transcript in their peripheral blood. Observations of several CP-CML cases responding remarkably well to dasatinib despite very low dose and frequent dose interruptions challenge our current understanding and the accuracy of the data regarding the optimum dose and schedule of this drug. In selected intolerant patients, low-dose dasatinib therapy may be a safe and effective alternative treatment option before a treatment discontinuation or change considered.
A high efficiency antenna with horn and lens for 77 GHz automotive long range radar

A high efficiency antenna with a pyramidal horn and a dielectric lens for a 77 GHz long range radar for automotives is presented in this paper. By introducing a single patch antenna installed into the input aperture of the horn, the transmission loss of the feed line on an antenna substrate was reduced so as to increase antenna gain. The proposed antennas for the transmitter achieved an antenna gain of 23.5 dBi and an antenna efficiency of 32.3%, which is 1.6 times as large as that of a conventional series-fed microstrip patch array antenna with almost the same opening area as the proposed antenna. The proposed antenna provided an azimuth 3-dB beamwidth of 16°, whereas the conventional series-fed microstrip patch array antenna had that of 10°. An antenna for a receiver with the same topology of the antenna for the transmitter also gave an antenna gain of 20.5 dBi per one channel and an azimuth 3-dB beamwidth of 28°. An antenna system for a long range radar composed of the proposed single transmitter antenna and the receiver antenna with two channels could provide a two-way antenna gain of 47.0 dBi and an azimuth 6-dB beamwidth of 23°.
Performances of UTC(OP) based on LNE-SYRTE atomic fountains

This paper presents the new method implemented since October 2012 to realize UTC(OP) at LNE-SYRTE, in Observatoire de Paris (OP), France. This time scale is based on a H-Maser steered by the LNE-SYRTE atomic fountains. We describe the algorithm and we discuss the results obtained over almost 2 years of operation. Since the implementation of the new method, the departure of UTC(OP) from UTC remained well below 10 ns.
MTPA Fitting and Torque Estimation Technique Based on a New Flux-Linkage Model for Interior-Permanent-Magnet Synchronous Machines

The characterization of the interior-permanent-magnet synchronous machine (IPMSM) is limited due to the nonlinearity of the flux-linkage profile by using the conventional motor model. A nonlinear flux-linkage model for the IPMSM with 12 coefficients is proposed in this paper. It can generally be used to estimate the real d-axis flux linkage, q-axis flux linkage, maximum-torque-per-ampere (MTPA) locus, and torque without the information of the machine known, such as the geometry and material of the permanent magnet. The corresponding torque equation and MTPA condition are presented. An optimization problem is formulated to find the appropriate factors for the proposed model based on the measured flux-linkage data at only nine specific operating points. No selection of weight factors is required in the cost function. The desired copper-loss minimization control can be achieved and good torque identification can be implemented in real time. Both simulation and experiment have been conducted to validate the proposed algorithm in motoring and generating modes. Compared with the conventional IPMSM model, the torque estimation accuracy has been significantly improved by considering the saturation and cross-coupling effects in the nonlinear flux-linkage model of the machine.
Design Principles for Inducing Reactivity in Ubiquitous Environments

Ubiquitous environments are becoming increasingly aware of their inhabitants: they posses vision capabilities, auditory capabilities and more interestingly intelligent capabilities. At the heart of such environments is the ability of systems to initiate responsive reactions to contextual changes. In this paper, we describe the concept of ubiquitous systems' reactivity. We identify important design principles that should be embraced by systems designers to build reactive systems that can engage users in richer and more meaningful interactions. Finally, we describe a prototype that we deployed in a domestic space and we explain how our design principles can help bridge the gap between end-users and ubiquitous systems.
Frequency Selective Surfaces for Extended Bandwidth Backing Reflector Functions

This paper deals with the use of frequency selective surfaces (FSS) to increase the efficiency X bandwidth product in wideband antenna arrays, whose efficiency is limited by the front-to-back ratio. If the backing reflector for the antenna is realized through a single metal plane solution, its location will be suitable only on a relatively limited frequency range especially if wide angle scanning is required. In order to extend the frequency range of usability, an FSS can be sandwiched between the antenna and the ground plane, providing an additional reflecting plane for an higher frequency band. The possibility to integrate in the antenna different functionalities, otherwise performed by several antennas, is also discussed in the paper. The proposed backing structure composed by the FSS and the ground plane has been designed to be used in conjunction with a wideband antenna consisting of an array of connected dipoles. A hardware demonstrator of the backing structure has also been manufactured and tested.

Grouping the Americas and Asia-Pacific Countries based on Their ICT Readiness, Prioritization of Travel & Tourism and Tourist Service Infrastructures

Travel and tourism competitiveness is a multi-pillars construct, each originating from measurement attempts. Involvement of governments, technology and tourism infrastructures are viewed as factors able to improve tourism competitiveness. This paper identifies principal components from these pillars for the Asia-Pacific and Americas considered most improved regions by the World Economic Forum (WEF). Five principal components were identified but three components were the most appropriate solution. A cluster analysis divided the countries into four groups offering a classification of the set. With their position presented in a scatter plot, countries can identify and select the best recommendations to their case depending on the group they belong to. Based on the cluster analysis results, it is seen that groups likes the Underachievers and Critical improvements would definitely need to improve their ICT level, while the Average Performers could as well benefit from technology improvements, although at a lesser degree. Specific examples discussed give better indications and recommendations to the countries as they can draw example from the explained cases to either adopt or adapt relevant strategies that would help their economy or avoid making similar mistakes.
Online Identification of Individual Driver Steering Behaviour and Experimental Results

Using switched systems, we model individual driver steering behaviour from a new point of view. This approach allows to incorporate the idea of human motion being built up by an individual and limited repertoire of learned patterns. The identification of the generating subsystem parameters of such individual motion primitives solely on measured output data requires a new identification method. We propose an algorithm using a multi-step model output error criterion and discuss different implementations in detail. We show that this method is capable of tracking real measurement data of driver steering motion trajectories with low model orders and number of switches respectively. The presented method is online-capable. Experimental driving results proof the concept.
Reduction of Mutual Coupling Between Strip Dipole Antennas at Terahertz Frequencies With an Elliptically Shaped Graphene Monolayer

In this letter, we propose to use the concept of the mantle cloaking method in order to reduce the mutual coupling between strip dipole antennas at low-terahertz (THz) frequencies. Here, we show that by covering each antenna with an elliptically shaped graphene monolayer, the electromagnetic interaction between the antennas can be suppressed drastically. The material properties of the graphene monolayer are properly tuned to provide the required surface reactance that leads to the restoration of the radiation patterns of the antennas as if they were isolated and uncoupled. The tunability of graphene with respect to its chemical potential allows us to reduce the mutual coupling between the antennas over a range of frequencies.
A comparison of low-cost techniques for three-dimensional animal body measurement in livestock buildings

Data about health and development of animals are still now mostly collected through manual measurements or visual observations but these kinds of methods of collecting data are causes of several problems. Alternatively, optical sensing techniques can be implemented in order to overcome limitations arising from manual contact measurements. The present research discusses metrological analysis of Structure from motion (SfM) photogrammetry approach, low-cost LiDAR scanning and Microsoft Kinect v1 depth camera to three-dimensional animal body measurement, with specific reference to pigs. Analyses were carried out on fiberglass model to get rid of animal movements. Scans were captured based on a segmented approach, where different portion of the body have been imaged during different frames acquisition tasks. The obtained results demonstrate the high potential of 3D Kinect. LiDAR show a higher RMS value respect to Kinect and SfM most probably due to the collection approach based on single profiles rather than on surfaces. Anyway, the RMS of relative noise ranges between 0.7 and 4 mm, showing a high accuracy of reconstructions even for the others techniques.
