GraSp: Combining Spatially‐aware Mobile Devices and a Display Wall for Graph Visualization and Interaction

Going beyond established desktop interfaces, researchers have begun re‐thinking visualization approaches to make use of alternative display environments and more natural interaction modalities. In this paper, we investigate how spatially‐aware mobile displays and a large display wall can be coupled to support graph visualization and interaction. For that purpose, we distribute typical visualization views of classic node‐link and matrix representations between displays. The focus of our work lies in novel interaction techniques that enable users to work with personal mobile devices in combination with the wall. We devised and implemented a comprehensive interaction repertoire that supports basic and advanced graph exploration and manipulation tasks, including selection, details‐on‐demand, focus transitions, interactive lenses, and data editing. A qualitative study has been conducted to identify strengths and weaknesses of our techniques. Feedback showed that combining mobile devices and a wall‐sized display is useful for diverse graph‐related tasks. We also gained valuable insights regarding the distribution of visualization views and interactive tools among the combined displays.
Quantification of Shigella IcsA required for bacterial actin polymerization.

Shigella move through the cytoplasm of host cells by active polymerization of host actin to form an "actin tail. " Actin tail assembly is mediated by the Shigella protein IcsA. The process of Shigella actin assembly has been studied extensively using IcsA-expressing Escherichia coli in cytoplasmic extracts of Xenopus eggs. However, for reasons that have been unclear, wild type Shigella does not assemble actin in these extracts. We show that the defect in actin assembly in Xenopus extracts by Shigella can be rescued by increasing IcsA expression by approximately 3-fold. We calculate that the number of IcsA molecules required on an individual bacterium to assemble actin filaments in extracts is approximately 1,500-2,100 molecules, and the number of IcsA molecules required to assemble an actin tail is approximately 4,000 molecules. The majority of wild type Shigella do not express these levels of IcsA when grown in vitro. However, in infected host cells, IcsA expression is increased 3.2-fold, such that the number of IcsA molecules on a significant percentage of intracellular wild type Shigella would exceed that required for actin assembly in extracts. Thus, the number of IcsA molecules estimated from our studies in extracts as being required on an individual bacterium to assemble actin filaments or an actin tail is a reasonable prediction of the numbers required for these functions in Shigella-infected cells.
Ultrasonic Scaler Oscillations and Tooth-surface Defects

Damage to tooth root surfaces may occur during ultrasonic cleaning with both piezoelectric and magnetostrictive ultrasonic scalers. It is unclear which mechanism causes more damage or how their mechanism of action leads to such damage. Our null hypothesis is that tooth-surface defect dimensions, resulting from instrumentation with ultrasonic scalers, are independent of whether the scaler probe is magnetostrictive or piezoelectric. Piezoelectric and magnetostrictive ultrasonic scaler probes were placed into contact against polished dentin samples (100 g/200 g). Resulting tooth surfaces were evaluated with a laser metrology system. Ultrasonic instrumentation produced an indentation directly related to the bodily movement of the probe as it made an impact on the surface. Load, generator power, and probe cross-section significantly affected probe vibration and defect depth/volume. Defect dimensions were independent of generator type. Magnetostrictive probes oscillated with greater displacement amplitudes than piezoelectric probes, but produced similar defects. This may be due to the cross-sectional shape of the probes.
Consolidation Model for a Simplified Computing Grid

Computing resources of both hardware and software tends to be located at a certain place. Computing grid that supports necessary application and required computing power offers the computing resources anywhere, if there is an Internet connection. A simple model of computing grid composed of computing sites is designed with a new representative of the grid, coordinator. It consolidates the computing sites in a manageable and transparent way. The application client connects to the grid by a Web browser. The access to a user data is allowed only after user authentication. The model is under implementation.
Distributed Dynamic Packet Scheduling for Handling Disturbances in Real-Time Wireless Networks

Real-time wireless networks (RTWNs) are fundamental to many Internet-of-Things (IoT) applications. Packet scheduling in an RTWN plays a critical role for achieving desired performance but is a challenging problem especially when the RTWN is large and subject to unexpected disturbances from the environment. Few solutions exist to tackle this challenge but they suffer serious limitations. This paper introduces a novel distributed dynamic packet scheduling framework, D2-PaS. D2-PaS aims to minimize the number of dropped packets while ensuring that all critical events due to disturbances are handled by their deadlines. D2-PaS builds on a number of observations that help reduce the scheduling overhead, and thus is efficient and scalable. Besides extensive simulation, D2-PaS has been implemented on an RTWN testbed to validate its applicability on real hardware. Both testbed measurements and simulation results confirm the effectiveness of D2-PaS. Compared to the best known work, D2-PaS reduces packet drop rates by 65% and 90% on average and in the best case, respectively, and also achieves 100% success for all the randomly generated task sets.
Make Some Noise! Member Mobilization In Trade Unions And Community Organizations

This study examines member mobilization using a British community organization and a British trade union as exemplars. Although there has been substantial work on union revitalization on the one hand, and the emergence of alternative, community organizations on the other, no study has compared the challenges these organizations face, in encouraging member mobilization. The focus is on member commitment and the organization’s legitimacy: the trade union gains merely pragmatic legitimacy from its members and the relationship between the member and the union is mainly instrumental, based on a negotiated exchange. The community organization, in contrast, gains moral legitimacy from its members and exemplifies a productive exchange between the members and the group.
Comparison of the workload of Dutch warmblood horses ridden normally and on a treadmill

Six Dutch warmblood horses, ridden by an experienced rider, cantered 3320 m at a speed adapted to the individual horse's anaerobic threshold, under four different conditions: 1, on a firm shell track with the speed varying from 6.5 to 9.4 m/s; 2, on a horizontal treadmill at the same speeds and for the same duration as in test 1; 3, on a horizontal treadmill for the same duration as in tests 1 and 2, but at a 10 per cent higher speed; and 4, on a treadmill at the same speed and for the same duration as in test 1, but at an inclination of 1 to 2 per cent adjusted individually to obtain heart rates similar to those recorded in test 1. On the basis of the heart rates and plasma lactate concentrations, the workload of the horses was significantly greater in the normal exercise test (1) than in the first treadmill test (2). Increasing the speed of the test on the horizontal treadmill by 10 per cent (test 3) resulted in heart rates and plasma lactate concentrations similar to those recorded in test 1. Inclining the treadmill on the basis of the heart rates achieved in test 1 had a less consistent effect than increasing the speed, but imitated a normal exercise test better than the horizontal treadmill test 2.
Predicting prostate specific antigen failure after radical retropubic prostatectomy for T1c prostate cancer.

PURPOSE Clinicopathological data were reviewed to find a predictor of prostate specific antigen (PSA) failure in Taiwanese patients who had received radical retropubic prostatectomy (RRP) for stage T1c prostate cancer (PC). METHODS Fifty-five consecutive men who underwent RRP for stage T1c PC were included. The clinical end point was PSA failure (PSA >0.2 ng/ml). Preoperative PSA, free-to-total PSA ratio, prostate volume, PSA density, transrectal sextant biopsy and whole mount of RRP parameters were analyzed for their ability to predict postoperative PSA failure. RESULTS Fifteen of the 55 patients developed PSA failure during the follow-up period. Those with PSA failure had higher PSA, higher percentage of cancer in biopsies and higher biopsy Gleason score than the freedom from PSA failure group (all P < 0.05). The PSA failure group had higher pathology Gleason score and a higher incidence of extracapsular tumor extension than the freedom from PSA failure group (all P < 0.05). The PSA failure group had a larger tumor volume and higher incidence of combined peripheral lobe with transitional lobe involvement than the freedom from PSA failure group (all P < 0.05). Multivariate analysis revealed that the predictors for PSA failure after RRP were biopsy Gleason score > or =6, tumor volume > or =2.5 ml and PSA > or =10 ng/ml. CONCLUSION The single most significant predictor for PSA failure in T1c PC patients after RRP was tumor volume > or =2.5 ml.
Serum prevalence to non-viral pathogens in wild felids of Southern Primorye, Russia

Serum prevalence to six different non-viral pathogens was estimated for big Russian cats (Amur tiger (Panthera tigris altaica) and the Far Eastern leopard (Panthera pardus orientalis)) in Southern Primorye, Russia (n = 26) in 2008–2016. Serum samples from smaller cats (Eurasian lynx (Lynx lynx) and Far Eastern wildcat (Prionailurus bengalensis euptilurus)) were also tested for these pathogens (n = 28) during the same period. Felids of Russian Southern Primorye showed serum prevalence to five out of six tested pathogens. Antibodies to Candida sp. and Trichinella sp. were found to be much more widespread in cats (47% and 42%) than antibodies to other tested pathogens (20% and less). Large cats demonstrated a higher serum prevalence to these pathogens than smaller ones. We did not detect animals seropositive to Coxiella burnetii.
Examining experience quality as the determinant of tourist behavior in niche tourism: an analytical approach

ABSTRACT Experience quality has been emerging as the dominant construct of interest for the success of the tourism industry. However, while a number of studies exist on experience quality in mass tourism, empirical investigation of experience quality in dark tourism has received less attention. This study investigates the direct and indirect effects of experience quality on loyalty intentions via perceived value and satisfaction in dark tourism. The research is conducted using data collected from 598 tourists visiting multiple dark tourism destinations in India. Findings confirm the presence of direct and indirect effects of experience quality on loyalty intentions through perceived value and satisfaction in dark tourism. Similarly, perceived value is found the more influential mediator than satisfaction in this niche tourism. In addition, the influence of experience quality on loyalty intentions is the strongest in dark tourism. These findings have several strategic implications for researchers and practitioners in dark tourism.
An Enhanced Affinity Graph for Image Segmentation

SUMMARY This paper proposes an enhanced a ﬃ nity graph (EA-graph) for image segmentation. Firstly, the original image is over-segmented to obtain several sets of superpixels with di ﬀ erent scales, and the color and texture features of the superpixels are extracted. Then, the similarity relationship between neighborhood superpixels is used to construct the local a ﬃ nity graph. Meanwhile, the global a ﬃ nity graph is obtained by sparse reconstruction among all superpixels. The local a ﬃ nity graph and global a ﬃ nity graph are superimposed to obtain an enhanced a ﬃ nity graph for eliminating the inﬂuences of noise and isolated regions in the image. Finally, a bipartite graph is introduced to express the a ﬃ l-iation between pixels and superpixels, and segmentation is performed us-ing a spectral clustering algorithm. Experimental results on the Berkeley segmentation database demonstrate that our method achieves signiﬁcantly better performance compared to state-of-the-art algorithms.
A high throughput fully parallel-pipelined FPGA accelerator for dense cloud motion analysis

Tracking of cloud characteristics helps in detecting cyclones which accounts for disastrous winds and heavy landfall on low lying coastal areas. Dense Motion Estimation is one of the most computationally intensive part of any tracking system. In this work we propose an efficient and high throughput hardware implementation of the Dense Horn-Schunck(DHSOF) algorithm to accelerate the cloud motion analysis software running on host PC. A Xilinx Virtex-7 FPGA interfaced to host PC via Peripheral Component Interconnect Express(PCIe) acts as hardware accelerator. The DHSOF architecture can process 3750×3750 resolution images in real-time (30fps), which is highest among the state of art methods in the literature. An analysis from the subsystem level to the whole design is performed to find optimal bit width for each stage. Results are verified using standard Middlebury dataset and validated using real world GOES-14 satellite images.
OPTIMAL INVESTMENT PROBLEM WITH OPTION

In this paper, the aim of the investor is to maximize expected return for a given level of risk. The model is based on a particular risk measure conditional value-at-risk (CVaR), the expected loss exceeding Value-at-Risk. The portfolio is optimized for investment in equity, debt and option on equity. In order to enhance the return potential, the expected return of intermittent re-investment payment obtained from option is also optimized. We develop a method to deal with the maximization of return of a portfolio in a two period context extending the work of Korn and Zeytun [4]. AMS Subject Classification: 49N05, 65K10
The Salmonella enterica Serovar Typhimurium Translocated Effectors SseJ and SifB Are Targeted to the Salmonella-Containing Vacuole

ABSTRACT The Salmonella enterica serovar Typhimurium type III secretion system (TTSS) encoded in Salmonella pathogenicity island 2 (SPI-2) promotes replication within host cells and systemic infection of mice. The SPI-2 TTSS is expressed following Salmonella internalization into host cells and translocates effectors across the membrane of the Salmonella-containing vacuole (SCV). Two effectors with similar amino-terminal domains, SseJ and SifB, localize to the SCV membrane in infected HEp-2 cells and subsequently traffic away from the SCV along Salmonella-induced-filaments (Sifs). Following infection of RAW cells, SseJ and SifB localize to the SCV as well as LAMP-1-positive, vesicular-appearing structures distant from the SCV. Trafficking of SseJ and SifB away from the SCV requires the SPI-2 effector SifA. Deletion of sseJ, but not sifB, leads to attenuation of Salmonella replication in mice following intraperitoneal inoculation. The contribution of SseJ to in vivo replication is identical in wild-type and sifA deletion backgrounds, suggesting that SseJ trafficking away from the SCV along Sifs is unnecessary for its virulence function.
Activation of the Ca2+‐Activated Nonselective Cation Channel by Diacylglycerol Analogues in Rat Cardiomyocytes

Introduction: Cardiac hypertrophy is associated with changes in electrophysiologic properties due to ionic channel modifications and increases in protein kinase C (PKC) activity and diacylglycerol (DAG) content. These changes may contribute to an increased propensity for arrhythmia. Similar electrophysiologic modifications have been reported in adult rat cardiomyocytes undergoing dedifferentiation in primary culture.
Separation/divorce and child and adolescent completed suicide.

OBJECTIVE To investigate factors that may modify the effect of separation/divorce on youth suicide. METHOD A case-control, psychological autopsy study of 120 of 170 consecutive suicides younger than age 20 and 147 community age-, sex-, and ethnic group-matched controls living in the greater New York area was conducted. Fifty-eight suicide victims and 49 community controls came from nonintact families of origin, indicating the permanent separation/divorce of the biological parents. Potential modifiers of separation/divorce include youth's age at separation, custodial parent's remarriage, nonresidential parent's frequency of contact, parent-child relationships, and parental psychopathology. RESULTS The relatively small impact of separation/divorce was further diminished after accounting for parental psychopathology. An interaction of separation/divorce and the father-child relationship emerged. CONCLUSION The dramatic increase in youth suicide during the past three decades seems unlikely to be attributable to the increase in divorce rates.
Effects of aerobic cycling training on cardiovascular fitness and heart rate recovery in patients with chronic stroke.

OBJECTIVE Using heart rate recovery (HRR) after exercise as an index of autonomic function, we evaluate the effects of aerobic cycling training on HRR and cardiovascular fitness (peak VO2) in chronic stroke patients and investigate the relationship between changes in HRR and those in peak VO2. METHODS 128 participants with chronic stroke were randomized to a 12-week (5×/week) progressive aerobic cycling training group (n = 65) or a control group (n = 63). Peak VO2, muscle strength, 6-minute walking distance (6MWD) and HRR were measured before and after the intervention. RESULTS Cycling training leads to significant increase in peak VO2, HRR, muscle strength and 6MWD. In the cycling group, percent changes in peak VO2 were positively associated with those in paretic and nonparetic muscle strength and HRR. Linear regression revealed that percent increases in peak VO2 were significantly correlated with percent changes in HRR when controlling for pre-peak VO2, age, gender, duration since stroke and improved muscle strength. CONCLUSION Aerobic cycling training can favorably modify HRR in stroke survivors. Rapid HRR, as an indicator of enhanced autonomic function, is useful for predicting gains in cardiovascular fitness. These findings indicate the underlying importance of autonomic modulation on cardiovascular adaptations to stroke exercise rehabilitation.
Prevalence and risk factors for diabetic retinopathy: the Korea National Health and Nutrition Examination Survey 2008-2011.

PURPOSE We evaluated the prevalence and risk factors for diabetic retinopathy (DR) in a representative Korean population. METHODS This cross-sectional study involved 16,109 subjects aged >40 years who had participated in the Korean National Health and Nutrition Survey from 2008 to 2011. Seven standard retinal fundus photographs were obtained after pupil dilatation from both eyes. The DR was graded using the modified Airlie House classification system. Risk factors for DR and vision-threatening diabetic retinopathy (VTDR) were evaluated, including age, sex, diabetes duration, glycated hemoglobin (HbA1c), hypertension, lipid profiles, and refractive error. RESULTS Of the 16,109 eligible individuals participating in the study, 14,595 (90.6%) had fasting blood glucose results available. Of these, 2023 (13.8%) were diagnosed with diabetes mellitus. Among these, gradable photographs were available for 1678 subjects (82.9%), including 1323 subjects with known diabetes mellitus (KDM) and 355 with newly diagnosed diabetes mellitus (NDM). The prevalences of any DR and VTDR were 15.8% (95% confidence interval [CI], 14.1-17.5), and 4.6% (95% CI, 3.6-5.6), respectively. Any DR was associated with a longer duration of diabetes (odds ratio [OR], 1.08; 95% CI, 1.06-1.10), higher HbA1C level (OR, 1.52; 95% CI, 1.28-1.80), higher systolic blood pressure (OR, 1.02; 95% CI, 1.01-1.03), and lower body mass index (OR, 0.91; 95% CI, 0.87-0.96) in a multivariate analysis. CONCLUSIONS We provide data on the prevalence and risk factors for DR in a representative Korean population. The prevalence of any DR and VTDR in the Korean population was lower than that reported previously. The condition of DR was associated with a longer duration of diabetes, poor glycemic control, and higher systemic blood pressure.
K+ dynamics in ischemic rat brain in vivo by 87Rb MRI at 7 T

The aims of the present study were as follows: (i) to perform the first 87Rb MRI in live rats with focal ischemic stroke; and (ii) to test the hypothesis that K+ egress from the brain in this model is quantifiable in individual animals by high‐field (7‐T) K/Rb substitution MRI. Rats preloaded with dietary Rb+ (resulting in Rb/(K + Rb) replacement ratios of 0.1–0.2 in the brain) were subjected to permanent occlusion of the middle cerebral artery, and 87Rb MRI was implemented with 13‐min temporal resolution using a dedicated RF coil and a spiral ultrashort‐TE sequence (TR/TE = 3/0.07 ms). The ischemic core was localized by apparent diffusion coefficient mapping, by microtubule‐associated protein‐2 immunohistochemistry and by changes in surface reflectivity. [K], [Na] and [Rb] were determined independently in the micropunched samples by post‐mortem flame photometry. Both techniques were generally in agreement in the nonischemic cortex; however, the MRI‐assessed [K+ + Rb+] drop in ischemic brain was less pronounced (average efflux rate of 4.8 ± 0.2 nEq/mm3/h versus 10 ± 1 nEq/mm3/h by flame photometry; p < 0.0001). The use of higher field gradients for better spatial resolution, and hence more accurate quantification, is suggested. Copyright © 2011 John Wiley & Sons, Ltd.
Therapist adherence to a motivational-interviewing intervention improves treatment entry for substance-misusing adolescents with low problem perception.

OBJECTIVE This study evaluated whether adherence to the Strengths-Oriented Referral for Teens (SORT) model, a motivational interviewing (MI)-consistent intervention addressing ambivalence about attending treatment, positively predicted adolescents' initial-session attendance. METHOD Therapist adherence was rated in 54 audiotaped SORT sessions by coders who were blind to treatment-entry status. Higher adherence scores reflected greater use of MI and solution focused language, discussion of client strengths, and dialogue with families on treatment need and options. RESULTS Therapist adherence during adolescent segments interacted with adolescent problem perception. Predicted probabilities of attending initial sessions increased for low-problem-perception adolescents at increasingly higher therapist adherence. CONCLUSIONS Although replication studies are needed, the SORT model of providing MI-consistent debriefing following initial assessments appears to be a promising approach for increasing treatment entry. Initial support for the treatment-matching hypothesis was found for substance-misusing adolescents contemplating treatment entry.
