Coordinating views in the InfoVis toolkit

Multidimensional data sets can be visualized in a variety of forms provided by many techniques described in the literature. Depending on specific tasks, users might need to analyze the same data set using different representations. Moreover, they might need to interact with a view and have the results shown also in the others. This paper presents a system to provide multiple coordinated views of multidimensional data. It activates the coordination of techniques provided by InfoVis as well as visualizations we implemented using its basic resources. We allow users to set which visualizations they want to coordinate through a diagram representing the different visualizations. We present the user-driven coordination scheme and extensions we made in InfoVis to allow coordinated views through different interaction tools.
Two Dimensions Simplex Evolution Algorithm

Under the basic frame of evolution computations (EA) and the kernel idea of Nelder-Mead simplex method, a novel evolution algorithm (EA), namely the two dimensions simplex EA (2D-simplexEA), is proposed. 2D-SimplexEA has four search operators: a reflection operator, a contraction operator, a plane search operator and a mutation operator. The first three operators and the forth operators are applied to the worst vertex and the best vertex respectively in order to reproduce a better vertex. The priority of the three operators for the worst vertex is the reflection operator, the contraction operator and the plane search operator, because there is a strong possibility that the reflection operator and the contraction operator can find out a new vertex better than the worst vertex along the optimal search direction of Nelder-Mead simplex method. When neither of them finds out a better vertex, the plane search operator is effective. It is the most important means for the best vertex to be improved by mutation without the other effective information and approaches. The numerical experiments verify 2D-SimplexEA correct and effective.

Will fish foster regenerative medicine in man?

In the February 3, 2011 issue of Nature, an elegant paper by Diep et al. [1] provided important clues on the cellular source that contributes to the regeneration of new functional nephrons during zebrafish growth and after injury. They first demonstrated partial restoration of the nephron function after gentamycin-induced injury, suggesting that some nephrons recovered in the kidney of adult zebrafish. To identify the cellular source of nephron regeneration, they used a transplantation assay based on immunocompromised (by radiation) nephrotoxin-injected recipient fish that received unpurified donor whole-kidney marrow cells tagged with different fluorescent proteins. Donor whole-kidney marrow cells, mostly comprising non-tubular interstitial cells, gave rise to functional nephrons which developed even in areas distant from the injected site and successfully integrated into the recipient’s renal tubules. Serial transplantation of donor whole-kidney marrow cells revealed that nephron progenitors were long-lived and bore robust self-renewing capacity. Only cell aggregates but not single nephron progenitors formed new nephrons as indicated by transgenic lineage-tracing experiments. In vivo imaging of nephrogenesis, performed on optically transparent larval zebrafish, confirmed that cell aggregates arose from the coalescence of three or four cell types that expanded to form a renal vesicle, which subsequently elongated into a nephron (Figure 1). Microarray analysis was performed to determine how similar zebrafish progenitor cells were to mouse cap mesenchyme cells, which represent the multipotent, selfrenewing progenitor population giving rise to podocytes, proximal and distal tubules during mammal kidney development [2]. A comparison of differentially expressed genes revealed that, despite having distinct molecular identities, the two cell populations shared a core set of regulatory genes conferring renal stem/progenitor cell potential.
Edit Distance Evaluation on Graph Structures

Graph data has became ubiquitous and manipulating them based on similarity is essential for many applications. Graph edit distance is one of the most widely accepted measure to determine similarities between graphs and has extensive applications in the fields of pattern recognition, computer vision etc. Unfortunately, the problem of graph edit distance computation is NP-Hard in general and is unlikely to be approximated within a polynomial time computable factor f(n) in polynomial time. Accordingly, in this paper we introduce three novel methods to compute the upper and lower bounds for the edit distance between two graphs in polynomial time. Applying these methods, three algorithms AppFull, ExactSub and AppSub are introduced to perform different kinds of graph search on graph databases. Comprehensive experimental studies are conducted on both real and synthetic datasets to examine various aspects of the methods for bounding graph edit distance. Result shows that these methods achieve good scalability in terms of both the number of graphs and the size of graphs. The effectiveness of these algorithms also confirms the usefulness of using our bounds in filtering and searching of graphs.
Fractionated versus Standard Continuous Light Delivery in Interstitial Photodynamic Therapy of Dunning Prostate Carcinomas

Purpose: The study aims to compare the standard/continuous light delivery with fractionated light delivery for interstitial photodynamic therapy (PDT) of prostate cancer. Experimental Design: Dunning R3327 prostate tumor models were established in male syngeneic rats. When tumors reached ∼3,000 mm3, animals were randomized to various treatment groups. Three hours after QLT0074 injection, tumors were illuminated by 690-nm light delivered by a computer-controlled switch, which sequentially directed light to one of the seven optical fibers in cycles. For comparison, tumors were treated with continuous illumination. Tumors treated with light-only served as control. Dynamic contrast-enhanced magnetic resonance imaging was used to monitor tumor perfusion changes before and after PDT. Results: Tumor response (animal survival) to PDT with fractionated light delivery was PDT dose dependent in both tumor models. Rats bearing anaplastic tumor treated by fractionated light (PDT dose: 1.5 mg/kg QLT0074, 900 J light) had a median survival of 51 days with 25% tumor cures compared with that of 26 days with no tumor cure by continuous illumination (P = 0.015) and 14 days by light-only (P = 0.0001). Rats bearing well-differentiated tumor treated by fractionated light had a median survival of 82 days compared with 65 days by continuous illumination (P = 0.001) and 37 days by light-only. PDT with fractionated light generated a perfusion reduction of 80% compared with 52% for continuous illumination in well-differentiated tumors. Conclusions: Fractionated light delivery is more effective than continuous light delivery in PDT of prostate cancer (solid tumors). These results warrant further investigation in clinical trials.
Solutions of the Euler and the Laminar and Turbulent Navier-Stokes Equations in Two-Dimensions Using TVD and ENO Algorithms

In the present work, the Yee, Warming and Harten and the Yang schemes are implemented, on a finite volume context and using a structured spatial discretization, to solve the Euler and the Navier-Stokes equations in two-dimensions. The former is a TVD high resolution scheme, whereas the latter is an ENO/TVD high resolution algorithm. Both schemes are flux difference splitting ones. An implicit formulation is employed to solve the Euler equations, whereas the Navier-Stokes equations are solved by an explicit formulation. Turbulence is taken into account considering the models of Cebeci and Smith, of Baldwin and Lomax and of Sparlat and Allmaras. The physical problems of the transonic flow along a convergent-divergent nozzle and the supersonic flow along a compression corner are studied in the inviscid case. In the viscous case, the supersonic flow along a ramp is solved. The results have demonstrated that all three algorithms present accurate results. Key-Words: Yee, Warming and Harten algorithm, TVD high resolution scheme, Yang algorithms, ENO/TVD high resolution schemes, Euler and Navier-Stokes equations, Turbulence models.
Algorithm based fault tolerance versus result-checking for matrix computations

Algorithm Based Fault Tolerance (ABFT) is the collective name of a set of techniques used to determine the correctness of some mathematical calculations. A less well known alternative is called Result Checking (RC) where, contrary to ABFT, results are checked without knowledge of the particular algorithm used to calculate them. In this paper a comparison is made between the two using some practical implementations of matrix computations. The criteria are performance and memory overhead: ease of use and error coverage. For the latter extensive error injection experiments were made. To the best of our knowledge, this is the first time that RC is validated by fault injection. We conclude that Result Checking has the important advantage of being independent of the underlying algorithm. It also has generally less performance overhead than ABFT, the two techniques being essentially equivalent in terms of error coverage.
Rape as a Weapon of War(riors): The Militarisation of Sexual Violence in the United States, 1990–2000

This article uses a transnational feminist lens to examine how accusations of sexual violence were mobilised by the United States (US) government to justify military intervention at the same time that the US military failed to address sexual violence perpetrated by and against its own service members. Drawing upon an archive of civilian representations ranging from the New York Times to G.I. Jane, the author explores US interventions in the Persian Gulf, Haiti and the former Yugoslavia alongside sexual assaults committed by servicemen at the Tailhook Convention, on Okinawa and at the Aberdeen Proving Grounds. This article draws connections between feminism and neo‐imperialism, between Cold War and War on Terror ideologies, and between rape as a weapon of war and rape during times of ‘peace’ in order to better understand the relationships between sexual politics and geopolitics at the end of the twentieth century.
Simulation performance of PID and fuzzy logic controller for higher order systems

The proportional-integral derivative controller (PID Controller) is a control loop feedback mechanism (Controller) widely used in automatic process control applications in industry today to regulate flow, temperature, pressure, level, and many other industrial process variables. The high demand of PID controller is due to its fine control capabilities in a wide range of operating conditions. This paper presents design of PID controller using Ziegler–Nichols (ZN) technique for higher order systems. A fuzzy logic controller using simple approach and smaller rule set is also proposed. The aim of designed fuzzy controller is to present better control compared with the existing PID controller. The simulation is done using Matlab/Simulink by comparing the performance of two controllers for higher order systems. It is finally observed that fuzzy logic controller has better control on timing parameters such as settling time, rise time, maximum overshoot as compared to the existing PID tuning techniques.
VEGFR-1 Overexpression Identifies a Small Subgroup of Aggressive Prostate Cancers in Patients Treated by Prostatectomy

The VEGFR-1 is suggested to promote tumor progression. In the current study we analyzed prevalence and prognostic impact of the VEGFR-1 by immunohistochemistry on a tissue microarray containing more than 3000 prostate cancer specimens. Results were compared to tumor phenotype, ETS-related gene (ERG) status, and biochemical recurrence. Membranous VEGFR-1 expression was detectable in 32.6% of 2669 interpretable cancers and considered strong in 1.7%, moderate in 6.7% and weak in 24.2% of cases. Strong VEGFR-1 expression was associated with TMPRSS2:ERG fusion status as determined by fluorescence in situ hybridization (FISH) and immunohistochemistry (p < 0.0001 each). Elevated VEGFR-1 expression was linked to high Gleason grade and advanced pT stage in TMPRSS2:ERG negative cancers (p = 0.0008 and p = 0.001), while these associations were absent in TMPRSS2:ERG positive cancers. VEGFR-1 expression was also linked to phosphatase and tensin homolog (PTEN) deletions. A comparison with prostate specific antigen (PSA) recurrence revealed that the 1.7% of prostate cancers with the highest VEGFR-1 levels had a strikingly unfavorable prognosis. This could be seen in all cancers, in the subsets of TMPRSS2:ERG positive or negative, PTEN deleted or undeleted carcinomas (p < 0.0001 each). High level VEGFR-1 expression is infrequent in prostate cancer, but identifies a subgroup of aggressive cancers, which may be candidates for anti-VEGFR-1 targeted therapy.
Link Technologies and BlackBerry Mobile Health (mHealth) Solutions: A Review

The number of wearable wireless sensors is expected to grow to 400 million by the year 2014, while the number of operational mobile subscribers has already passed the 5.2 billion mark in 2011. This growth results in an increasing number of mobile applications including: Machine-to-Machine (M2M) communications, Electronic-Health (eHealth), and Mobile-Health (mHealth). A number of emerging mobile applications that require 3G and 4G mobile networks for data transport relate to telemedicine, including establishing, maintaining, and transmitting health-related information, research, education, and training. This review paper takes a closer look at these applications, specifically with regard to the healthcare industry and their underlying link technologies. The authors believe that the BlackBerry platform and the associated infrastructure (i.e., BlackBerry Enterprise Server) is a logical and practical solution for eHealth, mHealth, sensor and M2M deployments, which are considered in this paper.
The wisdom of crowds: Predicting a weather and climate-related event

Environmental uncertainty is at the core of much of human activity, ranging from daily decisions by individuals to long-term policy planning by governments. Yet, there is little quantitative evidence on the ability of non-expert individuals or populations to forecast climate-related events. Here we report on data from a 90-year old prediction game on a climate related event in Alaska: the Nenana Ice Classic (NIC). Participants in this contest guess to the nearest minute when the ice covering the Tanana River will break, signaling the start of spring. Previous research indicates a strong correlation between the ice breakup dates and regional weather conditions. We study betting decisions between 1955 and 2009. We find the betting distribution closely predicts the outcome of the contest. We also find a significant correlation between regional temperatures as well as past ice breakups and betting behavior, suggesting that participants incorporate both climate and historical information into their decision-making.

It presents the issues of fusion of fuzzy geographical objects according to its storing modes (raster, vector) in a mutualised geographical information system (GIS). We study the aggregation of imprecise spatial entities and its impact in the imprecise description of quantities associated to space. It exposes the current choices in the Observox Project managing multiple sources of information.
El Papel de la Planifi cación de la Interacción en el Tratamiento de Adolescentes con Fobia Social Generalizada* The Role of Planned Interaction in the Treatment of Generalized Social Phobia

The aim of this study is to analyze the infl uence of planned interaction in the treatment of teenagers with generalized social phobia in two experimental conditions: 1) psychologically Constructed specifi c Treatment for the social phobia (Intervention in Teenagers with Social Phobia -IAFS - Olivares, 2005), and 2) Program of technologies of study with interaction between children and teachers. Participants were 25 teenagers who fulfi lled the criteria needed by the DSM-IV-TR (APA, 2002) for the diagnosis of widespread social phobia, selected among six public centers of Secondary Obligatory Education randomly, form the Region of Murcia and Valencia Community (Spain). The mean age of the sample were 14.99 years (ranging from 14 to 17), being the majority of them girls (71.3 %). The results show that teenagers who received Psychologically Constructed Treatment (IAFS) reached better results in the measures of anxiety, social avoidance and in the correlates of these (assertiveness, self-esteem, and adjustment) in comparison to the group that received technologies of study with interaction between equals.
User Descriptions and Interpretations of Self-Presentation through Facebook Profile Images

This article reports the findings of an open-ended qualitative survey about the choices people make when choosing profile images on Facebook. The results demonstrate that women tend to change their profile image more often and to emphasize friendship in the images they choose to display. Although both men and women are equally likely to display images of family and romantic relationships, the interpretations of such images may vary by gender. In addition, as one of the first Facebook studies to include users over 22 years old, this study provides comparative data demonstrating that older users are less likely to change their profile images frequently and more likely to display images of themselves alone. This study corroborates previous findings about the nature of self-presentation in online networking sites and offers new insights into how such impression management might vary according to age and gender.
Unstable GRB Photospheres and e± Annihilation Lines

We propose an emission mechanism of prompt gamma-ray bursts (GRBs) that can reproduce the observed nonthermal spectra with high radiative efficiencies, >50%. Internal dissipation below a photosphere can create a radiation-dominated thermal fireball. If e± pairs outnumber protons, radiative acceleration of e± pairs drives the two-stream instabilities between pairs and protons, leading to "proton sedimentation" in the accelerating pair frame. Pairs are continuously shock heated by proton clumps, scattering the thermal photons into a broken-power-law shape, with a nonthermal energy that is comparable to the proton kinetic energy, consistent with observations. Pair photospheres become unstable around the radius of the progenitor star where strong thermalization occurs, if parameters satisfy the observed spectral (Yonetoku) relation. Pair annihilation lines are predicted above continua, which could be verified by GLAST.
Effects of propolis and gamma‐cyclodextrin on intestinal neoplasia in normal weight and obese mice

Obesity is associated with colorectal cancer (CRC). This effect might be attributed to adipokine‐supported signaling. We have established that propolis suppresses survival signaling in CRC cells in vitro; therefore, we ascertained the ability of a propolis supplement to modulate intestinal neoplastic development in C57BL/6J‐ApcMin/+/J mice in the lean and obese state. To induce obesity, mice were fed with a Western diet containing 40% fat. Since the propolis supplement includes gamma‐cyclodextrin, the interventions included diets supplemented with or without gamma‐cyclodextrin. The animals were administered the following diets: (1) control diet, (2) control diet/gamma‐cyclodextrin, (3) control diet/propolis, (4) Western diet, (5) Western diet/gamma‐cyclodextrin, and (6) Western diet/propolis. Western diet, resulting in obesity, accelerated neoplastic progression, as evidenced by the larger size and higher grade dysplasia of the neoplasms. In the context of normal weight, gamma‐cyclodextrin and propolis affected neoplastic progression, as determined by the size of the lesions and their grade of dysplasia. A statistically significant decrease in the number of adenomas was detected in mice fed a control diet with the propolis supplement (61.8 ± 10.6 vs. 35.3 ± 7.6, P = 0.008). Although there was no significant difference in the polyp numbers between the six groups, the mice with the lowest number and size of adenomas were those fed a Western diet with gamma‐cyclodextrin. This unexpected outcome might be explained by the increased levels of apoptosis detected in the intestinal tissues of these obese mice. We posit that butyrate derived from the metabolism of gamma‐cyclodextrin may contribute to the decreased neoplastic burden in the context of obesity; however, future studies are required to address this possibility.
Performance Evaluation of a Three-Level ANPC Photovoltaic Grid-Connected Inverter With 650-V SiC Devices and Optimized PWM

Photovoltaic (PV) energy conversion has been on the spotlight of scientific research on renewable energy for several years. In recent years, the bulk of the research on PV has focused on transformerless grid-connected inverters, more efficient than traditional line transformer-based ones, but more critical from a power quality point of view, especially in terms of ground leakage current. Neutral-point-clamped (NPC) inverters have recently gained interest due to their intrinsically low ground leakage current and high efficiency, especially for MOSFET-based topologies. This paper presents an active NPC (ANPC) topology equipped with 650-V silicon carbide (SiC) MOSFETs, with a new modulation strategy that allows to reap the benefits of the wide-bandgap devices. An efficiency improvement is obtained due to the parallel operation of two devices during the freewheeling intervals. Simulations and experimental results confirm the effectiveness of the proposed converter.
An Incremental Approach to Adaptive Integration of Layers of a Hybrid Control Architecture

Hybrid deliberative-reactive control architectures are a popular and effective approach to the control of robotic navigation applications. However, due to the fundamental differences in the design of the reactive and deliberative layers, the design of hybrid control architectures can pose significant difficulties. We propose a novel approach to improving system-level performance of hybrid control architectures, by incrementally improving the deliberative layer’s model of the reactive layer’s execution of its plans. Incremental supervised learning techniques are employed to learn the model. Quantitative and qualitative results from a physics-based simulator are presented.
