Semantic multimedia-enhanced spatio-temporal queries in a crowdsourced environment

Social networks, such as Facebook, Instagram, and Twitter, provide intuitive ways to share a variety of information including geotagged multimedia data within users' communities of interest (COI) or publicly in real-time. Real-time geotagged multimedia data can provide semantics to conventional spatial queries in order to enrich the user navigation experience. In this paper, we introduce a mechanism to process spatio-temporal queries by leveraging geotagged multimedia data such as images, audio, video, and text, in order to add semantics to the conventional queries. Our framework collects, stores, and spatially tags multimedia data shared by users through social networks or through our developed mobile application. The system then uses such data in order to enhance the conventional routing services by resolving existing usability issues and by providing semantics to the routes in terms of enriched points of interest while taking dynamic road conditions into account. A proof of concept of the system will be demonstrated with the following spatio-temporal queries on road networks: 1) multimedia-enhanced shortest path queries; 2) multimedia-enhanced k-nearest neighbor queries; and 3) multimedia-enhanced range queries. Finally, a novel technique for finding lost individuals using geotagged multimedia data is also introduced. The results are tailor-made to the users' smartphone bandwidth and resolution requirements
Unfoldings: Multiple Explorations of Sound and Space

This paper describes a long term, collaborative project Sound Spaces. Within this project we creatively investigated various environments and built a collection of artworks in response to material gathered through a number of practical field visits. Our responses were presented in numerous, idiosyncratic ways and took shape through a number of concerted making activities. The work was conducted both in and with the public, allowing participants to inform the creative decisions made throughout the project as well as experiencing the building of the artworks. Within this essay we report on our process, presentation and offer alternative methods for collecting material and presenting representations of space using Ambisonic and other technologies. We describe the many responses made during our time and related these to research concerns relevant to the NIME community. We conclude with our findings and, through the production of an annotated portfolio, offer our main emerging themes as points of discussion.
Chromoendoscopy Detects More Adenomas than Colonoscopy Using Intensive Inspection without Dye Spraying

Conventional colonoscopy misses some neoplastic lesions. We compared the sensitivity of chromoendoscopy and colonoscopy with intensive inspection for detecting adenomatous polyps missed by conventional colonoscopy. Fifty subjects with a history of colorectal cancer or adenomas underwent tandem colonoscopies at one of five centers of the Great Lakes New England Clinical Epidemiology and Validation Center of the Early Detection Research Network. The first exam was a conventional colonoscopy with removal of all visualized polyps. The second exam was randomly assigned as either pan-colonic indigocarmine chromoendoscopy or standard colonoscopy with intensive inspection lasting >20 minutes. Size, histology, and numbers of polyps detected on each exam were recorded. Twenty-seven subjects were randomized to a second exam with chromoendoscopy and 23 underwent intensive inspection. Forty adenomas were identified on the first standard colonoscopies. The second colonoscopies detected 24 additional adenomas: 19 were found using chromoendoscopy and 5 were found using intensive inspection. Chromoendoscopy found additional adenomas in more subjects than did intensive inspection (44% versus 17%) and identified significantly more missed adenomas per subject (0.7 versus 0.2, P < 0.01). Adenomas detected with chromoendoscopy were significantly smaller (mean size 2.66 ± 0.97 mm) and were more often right-sided. Chromoendoscopy was associated with more normal tissue biopsies and longer procedure times than intensive inspection. After controlling for procedure time, chromoendoscopy detected more adenomas and hyperplastic polyps compared with colonoscopy using intensive inspection alone. Chromoendoscopy detected more polyps missed by standard colonoscopy than did intensive inspection. The clinical significance of these small missed lesions warrants further study.
Integral field spectroscopy of the ultraluminous X-ray source Holmberg II X-1

We present optical integral field observations of the H II region containing the ultraluminous X-ray source Holmberg II X-1. We confirm the existence of an X-ray ionized nebula as the counterpart of the source owing to the detec- tion of an extended He II λ4686 region (21 × 47 pc) at the Chandra ACIS-S position. An extended blue object with a size of 11 × 14 pc is coincident with the X-ray/He II λ4686 region, which could indicate that it is either a young stellar complex or a cluster. We have derived an X-ray to optical luminosity ratio of LX/LB ≥ 170, and presumable it is LX/LB ∼ 300−400 using the recent HST ACS data. We find a complex velocity dispersion at the position of the ULX. In addition, there is a radial velocity variation in the X-ray ionized region found in the He II emission of ±50 km s −1 on spatial scales of 2-3 �� . We believe that the pu- tative black hole not only ionizes the surrounding HII gas, but also perturbs it dynamically (via jets or the accretion disk wind). The spatial analysis of the public Chandra ACIS-S data reveals a point-like X-ray source and gives marginal indication of an extended component (� 15% of the total flux). The XMM-Newton EPIC-PN spectrum of HoII X-1 is best fitted with an absorbed power law in addition to either a thermal thick plasma or a thermal thin plasma or a multi-colour disk black body (MCD). In all cases, the thermal component shows a relatively low temperature (kT ∼ 0.14−0.22 keV). Finally we discuss the optical/X-ray properties of HoII X-1 with regards to the possible nature of the source. The existence of an X-ray ionized nebula coincident with the ULX and the soft X-ray component with a cool accretion disk favours the interpretation as an intermediate-mass black hole (IMBH). However, the complex velocity behaviour at the position of the ULX indicates a dynamical influence of the black hole on the local HII gas.
The spinning-top Be star Achernar from VLTI-VINCI

We report here the first observations of a rapidly rotating Be star, Eridani, using Earth-rotation synthesis on the Very Large Telescope (VLT) Interferometer. Our measures correspond to a 2a=2b= 1:56 0:05 apparent oblate star, 2a and 2b being the equivalent uniform disc angular diameters in the equatorial and polar direction. Considering the presence of a circum- stellar envelope (CSE) we argue that our measurement corresponds to a truly distorted star since Eridani exhibited negligible H emission during the interferometric observations. In this framework we conclude that the commonly adopted Roche approx- imation (uniform rotation and centrally condensed mass) should not apply to Eridani. This result opens new perspectives to basic astrophysical problems, such as rotationally enhanced mass loss and internal angular momentum distribution. In addition to its intimate relation with magnetism and pulsation, rapid rotation thus provides a key to the Be phenomenon: one of the outstanding non-resolved problems in stellar physics.
Analyzing Relative Incompleteness of Movie Descriptions in the Web of Data: A Case Study

In the context of Linked Open Data (LOD) [3], datasets are published or updated frequently, constantly changing the landscape of the Linked Data Cloud. In this paper we present a case study, investigating relative incompleteness among subgraphs of three Linked Open Data (LOD) datasets (DBpedia (dbpedia.org), Freebase (www.freebase.com), LinkedMDB (www.linkedmdb.com)) and propose measures for relative data incompleteness in LOD. The study provides insights into the level of accuracy and actual conflicts between different LOD datasets in a particular domain (movies). In addition, we investigate the impact of the neighbourhood size (i.e. path length) under consideration, to better understand the reliability of cross-dataset links. Fig. 1 presents an example of relative incompleteness in the representation of movie entity “Holy Smoke! ” in DBpedia and Freebase. In this example, the difference between the actor sets indicates the “Movie.Actor” property might be incomplete. As we do not know the exact complete set of actors and the noise observed in linked datasets interferes completeness estimation, we call this phenomenon relative incompleteness. If we follow the “Movie.Cinematographer” link in the data graphs of the two datasets, we can observe further relative incompleteness in its “birthPlace” property.
HpMC: An Energy-aware Management System of Multi-level Memory Architectures

DRAM technology faces density and power challenges to increase capacity because of limitations of physical cell design. To overcome these limitations, system designers are exploring alternative solutions that combine DRAM and emerging NVRAM technologies. Previous work on heterogeneous memories focuses, mainly, on two system designs: PCache, a hierarchical, inclusive memory system, and HRank, a flat, non-inclusive memory system. We demonstrate that neither of these designs can universally achieve high performance and energy efficiency across a suite of HPC workloads. In this work, we investigate the impact of a number of multi-level memory designs on the performance, power, and energy consumption of applications. To achieve this goal and overcome the limited number of available tools to study heterogeneous memories, we created HMsim, an infrastructure that enables n-level, heterogeneous memory studies by leveraging existing memory simulators. We, then, propose HpMC, a new memory controller design that combines the best aspects of existing management policies to improve performance and energy. Our energy-aware memory management system dynamically switches between PCache and HRank based on the temporal locality of applications. Our results show that HpMC reduces energy consumption from 13% to 45% compared to PCache and HRank, while providing the same bandwidth and higher capacity than a conventional DRAM system.
Further evidence for eagle predation of, and feeding damage on, the Taung child

We present new evidence supporting the hypothesis that a large raptor was responsible for the death of the c. 2.0-Myr-old Taung child, holotype of the early hominin species Australopithecus africanus. We compare the Taung child's skull with those of monkeys killed and eaten by modern crowned eagles, Stephanoaetus coronatus, in the Ivory Coast's Tai Forest. Close inspection of primate feeding remains from these large, powerful raptors reveals scratch marks in the orbital, frontal, temporal, parietal and occipital regions. Scratches similar in size and distribution are also present on the Taung child's skull. The new taphonomic evidence, combined with previously recognized similarities in breakage patterns and other assemblage characteristics, bolsters the case that a large bird of prey was responsible for the death of the juvenile hominin from Taung.
An elastically tethered viscous load imposes a regular gait on the motion of myosin-V. Simulation of the effect of transient force relaxation on a stochastic process

Myosin-V is a processive molecular motor that moves membrane vesicles along actin tracks. In the simple model for motor and cargo motion investigated here, an elastic connection between motor and cargo transiently absorbs the abrupt mechanical transitions of the motor, and allows smooth relaxation of the cargo to a new position. We use a stochastic description to model motor stepping, with kinetics that depends on the instantaneous force exerted on the motor through the elastic connection. Tether relaxation is modelled as a continuous process, in which the rate is determined by the viscous drag of the cargo and the stiffness profile of the connection. Quantitative combined stochastic–continuous simulation of the dynamics of this system shows that bulky loads can impose a highly regular gait on the motor. If the characteristics of the elastic connection are similar to those of the myosin-II coiled-coil domain, the myosin-V motor, tether and cargo form a true escapement, in which the motor only escapes from its current position after one or more force thresholds have been crossed. Multiple thresholds limit the variation in tether length to values below that of the total step size.
Adenovirus-Mediated Expression of the p14 Fusion-Associated Small Transmembrane Protein Promotes Cancer Cell Fusion and Apoptosis In Vitro but Does Not Provide Therapeutic Efficacy in a Xenograft Mouse Model of Cancer

Adenoviruses (Ads) are used in numerous preclinical and clinical studies for delivery of anti-cancer therapeutic genes. Unfortunately, Ad has a poor ability to distribute throughout a tumor mass after intratumoral injection, and infects cells primarily within the immediate area of the injection tract. Thus, Ad-encoded transgene expression is typically limited to only a small percentage of cells within the tumor. One method to increase the proportion of the tumor impacted by Ad is through expression of fusogenic proteins. Infection of a single cell with an Ad vector encoding a fusogenic protein should lead to syncytium formation with adjacent cells, effectively spreading the effect of Ad and Ad-encoded therapeutic transgenes to a greater percentage of the tumor mass. Moreover, syncytium formation can be cytotoxic, suggesting that such proteins may be effective sole therapeutics. We show that an early region 1 (E1)-deleted Ad expressing reptilian reovirus p14 fusion-associated small transmembrane (FAST) protein caused extensive cell fusion in the replication-permissive 293 cell line and at high multiplicity of infection in non-permissive human lung adenocarcinoma A549 cells in vitro. FAST protein expression in the A549 cancer cell line led to a loss of cellular metabolic activity and membrane integrity, which correlated with induction of apoptosis. However, in an A549 xenograft CD-1 nude mouse cancer model, Ad-mediated FAST gene delivery did not induce detectable cell fusion, reduce tumor burden nor enhance mouse survival compared to controls. Taken together, our results show that, although AdFAST can enhance cancer cell killing in vitro, it is not effective as a sole therapeutic in the A549 tumor model in vivo.
Has Income-related Inequity in Health Care Utilization and Expenditures Been Improved? Evidence From the Korean National Health and Nutrition Examination Survey of 2005 and 2010

Objectives The purpose of this study is to examine and explain the extent of income-related inequity in health care utilization and expenditures to compare the extent in 2005 and 2010 in Korea. Methods We employed the concentration indices and the horizontal inequity index proposed by Wagstaff and van Doorslaer based on one- and two-part models. This study was conducted using data from the 2005 and 2010 Korean National Health and Nutrition Examination Survey. We examined health care utilization and expenditures for different types of health care providers, including health centers, physician clinics, hospitals, general hospitals, dental care, and licensed traditional medical practitioners. Results The results show the equitable distribution of overall health care utilization with pro-poor tendencies and modest pro-rich inequity in the amount of medical expenditures in 2010. For the decomposition analysis, non-need variables such as income, education, private insurance, and occupational status have contributed considerably to pro-rich inequality in health care over the period between 2005 and 2010. Conclusions We found that health care utilization in Korea in 2010 was fairly equitable, but the poor still have some barriers to accessing primary care and continuing to receive medical care.
Toward a Maturity Model Development Process for Information Systems (MMDePSI)

Maturity models are significant tools to ensure continuous improvement of systems and activities. They allow selfassessment and provide a means benchmark of these activities in relation to best practices. This article proposes the MMDePSI process for the development of new models of maturity in information systems. It begins by presenting the existing methods and approaches. Then he describes the MMDePSI process and the corresponding meta-model. Before concluding and presenting prospects of this work, it evaluates the proposed process.
Employment and Growth Effects of Tax Reforms

This paper explores how revenue-neutral tax reforms impact employment and economic growth in a model of endogenous growth and search frictions on the labor market. We analyze how savings and the incentive to create new jobs are affected by tax swaps between wage income taxes, payroll taxes, capital income taxes and taxes levied on capital costs. In our framework, the payroll tax is found to be neutral. If this tax is used to finance a cut in the capital income tax, we will observe an increase in both growth and, via the capitalization effect, employment. Most other tax reforms, however, imply a trade-off between employment and growth.
Diving Head-First into Virtual Reality: Evaluating HMD Control Schemes for VR Games

Virtual reality games are on the cusp of mainstream acceptance and introduce a new input channel in the form of the head mounted display. Head tracking input can be mapped to several functions in the game world such as camera view, targeting and avatar movement direction. However, the role of head tracking in control schemes for virtual reality games is often overlooked. We evaluate how player performance and experience is affected by HMD control schemes in the first-person PC game Team Fortress 2 . The “coupled” control scheme (in which both the mouse and HMD control camera view, targeting and movement direction) had the highest performance scores of the VR control schemes. Nonetheless, the schemes with the lowest performance scores gave the best player experience in terms of self-reported immersion and player preferences. This research refocuses attention on HMDs and provides empirical findings that can guide designers when integrating head tracking input into control schemes.
Overeducation, skills and social background: the influence of parental education on overeducation in Spain

ABSTRACT This article focuses on the influence of social background on overeducation in Spain, understanding family socialisation as a source of knowledge and skills gain. The dramatic education expansion experienced in Spain in combination with a high percentage of low-skilled jobs has promoted overeducation occurrence to a larger extent than in other Organisation for Economic Cooperation and Development (OECD) countries. Using the Survey of Adult Skills (PIAAC) data results suggest that overeducation affects at least over a quarter of the working population. Younger and middle aged workers are more likely to be overeducated compared to the senior ones, while women are more prone to be overeducated than men. Workers whose mothers have higher education are less likely to be overeducated compared to those whose mothers have basic education, while fathers’ education is practically irrelevant to predict workers’ overeducation. Thus, a mother’s education is the most relevant social background indicator to predict overeducation, even when controlling for firm characteristics and skills level.
Cue self-relevance affects autobiographical memory specificity in individuals with a history of major depression

Previously depressed and never-depressed individuals identified personal characteristics (self-guides) defining their ideal, ought, and feared selves. One week later they completed the autobiographical memory test (AMT). For each participant the number of AMT cues that reflected self-guide content was determined to produce an index of AMT cue self-relevance. Individuals who had never been depressed showed no significant relationship between cue self-relevance and specificity. In contrast, in previously depressed participants there was a highly significant negative correlation between cue self-relevance and specificity—the greater the number of AMT cues that reflected self-guide content, the fewer specific memories participants recalled. It is suggested that in individuals with a history of depression, cues reflecting self-guide content are more likely to prompt a shift to processing of information within the long-term self (Conway, Singer, & Tagini, 2004), increasing the likelihood that self-related semantic information will be provided in response to cues on the autobiographical memory test.
The Contribution of a “Supportive Community” Program for Older Persons in Israel to Their Offspring Who Are Primary Caregivers

The “supportive community” programs in Israel provide a basket of services for older persons living in their own homes. This study examined the differences between caregiver burden and quality of life of 55 offspring who were the primary caregivers of their older parents who were members of a supportive community, compared to 64 offspring whose parents were nonmembers. The findings showed that the role stress factor of caregiving burden was lower, and the psychological health domain of quality of life was higher among offspring whose parents were members of supportive communities. Some of the predictor variables of burden were income status of caregiver, sharing with others in caregiving, and membership of the parent in a supportive community. The primary predictor variable of the quality of life was caregiving burden. The practical conclusion of this study is to further develop and market supportive community programs in various communities.
Vitamin D intake is inversely associated with rheumatoid arthritis: results from the Iowa Women's Health Study.

OBJECTIVE Vitamin D is a potent regulator of calcium homeostasis and may have immunomodulatory effects. The influence of vitamin D on human autoimmune disease has not been well defined. The purpose of this study was to evaluate the association of dietary and supplemental vitamin D intake with rheumatoid arthritis (RA) incidence. METHODS We analyzed data from a prospective cohort study of 29,368 women of ages 55-69 years without a history of RA at study baseline in 1986. Diet was ascertained using a self-administered, 127-item validated food frequency questionnaire that included supplemental vitamin D use. Risk ratios (RRs) and 95% confidence intervals (95% CIs) were estimated using Cox proportional hazards regression, adjusting for potential confounders. RESULTS Through 11 years of followup, 152 cases of RA were validated against medical records. Greater intake (highest versus lowest tertile) of vitamin D was inversely associated with risk of RA (RR 0.67, 95% CI 0.44-1.00, P for trend = 0.05). Inverse associations were apparent for both dietary (RR 0.72, 95% CI 0.46-1.14, P for trend = 0.16) and supplemental (RR 0.66, 95% CI 0.43-1.00, P for trend = 0.03) vitamin D. No individual food item high in vitamin D content and/or calcium was strongly associated with RA risk, but a composite measure of milk products was suggestive of an inverse association with risk of RA (RR 0.66, 95% CI 0.42-1.01, P for trend = 0.06). CONCLUSION Greater intake of vitamin D may be associated with a lower risk of RA in older women, although this finding is hypothesis generating.
