A Learning-based Frame Pooling Model For Event Detection

Detecting complex events in a large video collection crawled from video websites is a challenging task. When applying directly good image-based feature representation, e.g., HOG, SIFT, to videos, we have to face the problem of how to pool multiple frame feature representations into one feature representation. In this paper, we propose a novel learning-based frame pooling method. We formulate the pooling weight learning as an optimization problem and thus our method can automatically learn the best pooling weight configuration for each specific event category. Experimental results conducted on TRECVID MED 2011 reveal that our method outperforms the commonly used average pooling and max pooling strategies on both high-level and low-level 2D image features.
UNINTENDED NEGATIVE CONSEQUENCES effective at improving children ' s self-management of health problems , such as asthma and diabetes

Computer technology has revolutionized a wide variety of tasks from communication and scientific calculations to entertainment and education. However, any new tool or technology may be misused or may create unintended negative consequences. In the case of video games, technology has seen considerable success in entertaining users and teaching specific content However, what they teach depends upon their content, regardless of the intent of the game creators or the end users. In the case of violent video games, research has demonstrated conclusively that these games can have deleterious effects on the user. Regardless of the research design (e.g., crosssectional or experimental) and outcome measures used (e.g., anger, aggressive thoughts, or aggressive behavior), research consistently shows that violent video games can increase aggression. Children and young adults, males and females, high aggressive and low aggression people are all susceptible to increases in aggression, after even short exposures to violent video games. Key Terms: violence, video games, aggression, consequence
The neofonie NERD system at the ERD challenge 2014

This paper describes Neofonie NERD, our Named Entity Recognition and Disambiguation system submitted to the ERD Challenge 2014. The system uses a vector space model approach for disambiguation, based on the link structure of Freebase, in combination with precomputed statistical measures from Wikipedia and Freebase. It was originally developed for the German language and has now been adapted for English. We achieved 70.0% F1-score in the final evaluation, which is 5.7 percent points above the average of all participating teams.
Home Service Communities and Authentication

Home networks have been more and more present in today life, delivering miscellaneous services to end users. Then one opportunity consists in deploying services between home networks (service communities). However it requires networking interconnection and efficient authentication mechanisms. According to this context, this paper proposes two network architectures to support home service communities and compares them with the IMS one as a reference solution. One architecture is based on a centralized SIP solution using HTTP digest for authentication whereas the other one is a pure P2P overlay integrating Identity based cryptography. The analysis and comparison of architecture signaling load is undergone through the simulation of a simple photo sharing scenario. Eventually the different solutions propose their own advantages: P2P based solution can be easily deployed for small communities and may be compliant to larger system if research algorithms are improved. SIP central solutions can be relevant for an average number of users and they are the easiest way to deploy new services.
Central Aortic Reservoir-Wave Analysis Improves Prediction of Cardiovascular Events in Elderly Hypertensives

Several morphological parameters based on the central aortic pressure waveform are proposed as cardiovascular risk markers, yet no study has definitively demonstrated the incremental value of any waveform parameter in addition to currently accepted biomarkers in elderly, hypertensive patients. The reservoir-wave concept combines elements of wave transmission and Windkessel models of arterial pressure generation, defining an excess pressure superimposed on a background reservoir pressure. The utility of pressure rate constants derived from reservoir-wave analysis in prediction of cardiovascular events is unknown. Carotid blood pressure waveforms were measured prerandomization in a subset of 838 patients in the Second Australian National Blood Pressure Study. Reservoir-wave analysis was performed and indices of arterial function, including the systolic and diastolic rate constants, were derived. Survival analysis was performed to determine the association between reservoir-wave parameters and cardiovascular events. The incremental utility of reservoir-wave parameters in addition to the Framingham Risk Score was assessed. Baseline values of the systolic rate constant were independently predictive of clinical outcome (hazard ratio, 0.33; 95% confidence interval, 0.13–0.82; P=0.016 for fatal and nonfatal stroke and myocardial infarction and hazard ratio, 0.38; 95% confidence interval, 0.20–0.74; P=0.004 for the composite end point, including all cardiovascular events). Addition of this parameter to the Framingham Risk Score was associated with an improvement in predictive accuracy for cardiovascular events as assessed by the integrated discrimination improvement and net reclassification improvement indices. This analysis demonstrates that baseline values of the systolic rate constant predict clinical outcomes in elderly patients with hypertension and incrementally improve prognostication of cardiovascular events.
On the observer canonical form for Nonlinear Time–Delay Systems

Abstract Necessary and sufficient geometric conditions for the equivalence of a nonlinear time–delay system with one output, under bicausal change of coordinates and output transformation, to a linear weakly observable time–delay system up to output injection are given. These conditions are derived through the use of the Extended Lie Bracket operator recently introduced in the literature for dealing with time–delay systems. The results presented show how this operator is useful in the analysis of this class of nonlinear systems.
Fuzzy granular gravitational clustering algorithm

Given the nature of clustering algorithms of finding automatically, or semi-automatically, an unspecified number of clusters, much work has been done in this area. This paper will introduce a proposed gravitational model for finding clusters, the algorithm is based on the gravitational forces from Newton's law of universal gravitation and the output clusters are then fuzzified. Two examples of datasets are compared, one synthetic and one of the Iris, are benchmarked against the fuzzy subtractive algorithm.
S-clause segmentation for efficient syntactic analysis using decision trees

In dependency parsing of long sentences with fewer subjects than predicates, it is difficult to recognize which predicate governs which subject. To handle such syntactic ambiguity between subjects and predicates, this paper proposes an “Sclause” segmentation method, where an S(ubject)clause is defined as a group of words containing several predicates and their common subject. We propose an automatic S-clause segmentation method using decision trees. The S-clause information was shown to be very effective in analyzing long sentences, with an improved performance of 5 percent.
The crustal structure from the Altai Mountains to the Altyn Tagh fault, northwest China

[1] We present a new crustal section across northwest China based on a seismic refraction profile and geologic mapping. The 1100-km-long section crosses the southern margin of the Chinese Altai Mountains, Junggar Accretional Belt and eastern Junggar basin, easternmost Tianshan Mountains, and easternmost Tarim basin. The crustal velocity structure and Poisson's ratio (σ), which provide a constraint on crustal composition, were determined from P and S wave data. Despite the complex geology, the crustal thickness along the entire profile is nearly uniform at 50 km. The thickest crust (56 km) occurs at the northern end of the profile beneath the Altai Mountains and the thinnest (46 km) crust is beneath the Junggar basin. Beneath surficial sediments, the crust is found to have three layers with P wave velocities (Vp) of 6.0–6.3, 6.3–6.6, and 6.9–7.0 km/s, respectively. The southern half of the profile, including the eastern Tianshan Mountains and eastern margin of the Tarim basin, shows low P wave velocities and σ = 0.25 to a depth of 30 km, which suggests a quartz-rich, granitic upper crustal composition. The northern half of the profile below the Altai Mountains and Junggar Accretional Belt has a higher Poisson's ratio of σ = 0.26–0.27 to a depth of 30 km, indicative of an intermediate crustal composition. The entire 1100-km-long profile is underlain by a 15–30 km thick high velocity (6.9–7.0 km/s; σ = 0.26–0.28) lower-crustal layer that we interpret to have a bulk composition of mafic granulite. At the southern end of the profile, a 5-km-thick midcrustal low-velocity layer (Vp = 5.9 km/s, σ = 0.25) underlies the Tianshan and the region to the south, and may be indicative of a near-horizontal detachment interface. Pn velocities are ∼7.7–7.8 km/s between the Tianshan and the Junggar basin, and ∼7.9–8.0 km/s below the Altai Mountains and eastern margin of the Tarim basin. We interpret the consistent three-layer stratification of the crust to indicate that the crust has undergone partial melting and differentiation after Paleozoic terrane accretion. The thickness (50 km) of the crust appears to be related to compression resulting from the Indo-Asian collision.
Sensor Modeling, Low-Complexity Fusion Algorithms, and Mixed-Signal IC Prototyping for Gas Measures in Low-Emission Vehicles

This paper addresses the detection of hydrogen leaks for safety warning systems in automotive applications and the measurement of nitrogen oxide concentration in exhaust gases of zero-emission vehicles. The presented approach is based on the development of accurate models (including nonlinearity and error sources of real building components) for all the system elements: sensors and acquisition chain. This methodology enables efficient design space exploration and sensitivity analysis, allowing an optimal analog-digital and hardware-software partitioning. Such analysis drives also the development of effective data fusion techniques to reduce the measure uncertainty (due to cross-sensitivity to other gases or to temperature/humidity variations). Such techniques have been implemented on a microcontroller-based mixed-signal embedded platform for intelligent sensor interfacing with limited complexity, suitable for automotive applications.

The strain belongs to the distinct IBDV lineage that is widely distributed in South America.
Design and optimization of an axially-slitted high-speed solid rotor induction motor

Axially-Slitted Solid Rotor Induction Motor (ASSRIM) has a better electric and electromagnetic performance in comparison to Smooth Solid Rotor Induction Motor (SSRIM) in high-speed drive application. A better flux penetration into rotor and increased rotor cooling capability can be performed with axial slits on rotor. The main drawbacks of the axially slits are decreased rotor bending resistance and increased air friction losses. In this study, 20.5 kW, 23600 min-1 high-speed ASSRIM is designed and geometric design parameters of slits such as slit depth and width are optimized by finite element method (FEM). In order to determine optimal geometrical parameters, desired parameters are changed in order; others are kept constant while one is being optimized. 2D transient magnetic model is used for optimization.
A Closed-Form Method for LRU Replacement under Generalized Power-Law Demand

We consider the well known \emph{Least Recently Used} (LRU) replacement algorithm and analyze it under the independent reference model and generalized power-law demand. For this extensive family of demand distributions we derive a closed-form expression for the per object steady-state hit ratio. To the best of our knowledge, this is the first analytic derivation of the per object hit ratio of LRU that can be obtained in constant time without requiring laborious numeric computations or simulation. Since most applications of replacement algorithms include (at least) some scenarios under i.i. d. requests, our method has substantial practical value, especially when having to analyze multiple caches, where existing numeric methods and simulation become too time consuming.
Remote monitoring and follow-up of pacemakers and implantable cardioverter defibrillators

In the era of communication technology, new options are now available for following-up patients implanted with pacemakers (PMs) and defibrillators (ICDs). Most major companies offer devices with wireless capabilities that communicate automatically with home transmitters, which then relay data to the physician, thereby allowing remote patient follow-up and monitoring. These systems are being widely used in the USA for remote follow-up, and have been more recently introduced in Europe, where their adoption is increasing. In this article, we describe the currently existing systems, review the available evidence in the literature regarding remote follow-up and monitoring of PMs and ICDs, and finally discuss some unresolved issues.
Flexible Release Composition using Integer Linear Programming

For software vendors, the process to determine the requirements for the next release of a software product is often difficult. In this paper we present a mathematical formalization of release composition with a corresponding optimization tool that aims to support product managers and development project managers during release planning. The tool is based on integer linear programming and assumes that an optimal set of requirements is the set with maximum projected revenue against available resources in a given time period. The input for the optimization is twofold. Input data like the list of candidate requirements, estimated revenue and required team resources per requirement, whether or not a requirement is mandatory, comprise the first type of input. Secondly, several managerial steering mechanisms provide flexibility in the optimization environment: team composition, permitting of team transfers, extension of deadlines, and hiring external resources. Through experiments based on real-life data we make a sound case for the applicability of our proposal. 1 Requirements selection for release planning Companies developing software products face complex challenges when determining requirements for upcoming releases (see e.g. Potts (1995); Regnell and Brinkkemper, (2005)). Often the wish-list of requirements extends the capacity of available resources, requirements may not be unambiguous, they may be difficult to prioritize, etc. As a matter of fact, many aspects influence the definition of an optimal set of requirements for a next release.

Cryo‐fluorescence microscopy facilitates correlations between light and cryo‐electron microscopy and reduces the rate of photobleaching

Fluorescence light microscopy (LM) has many advantages for the study of cell organization. Specimen preparation is easy and relatively inexpensive, and the use of appropriate tags gives scientists the ability to visualize specific proteins of interest. LM is, however, limited in resolution, so when one is interested in ultrastructure, one must turn to electron microscopy (EM), even though this method presents problems of its own. The biggest difficulty with cellular EM is its limited utility in localizing macromolecules of interest while retaining good structural preservation. We have built a cryo‐light microscope stage that allows us to generate LM images of vitreous samples prepared for cryo‐EM. Correlative LM and EM allows one to find areas of particular interest by using fluorescent proteins or vital dyes as markers within vitrified samples. Once located, the sample can be placed in the EM for further study at higher resolution. An additional benefit of the cryo‐LM stage is that photobleaching is slower at cryogenic temperatures (−140°C) than at room temperature.
An Alternative to Null-Hypothesis Significance Tests

The statistic P rep estimates the probability of replicating an effect. It captures traditional publication criteria for signal-to-noise ratio, while avoiding parametric inference and the resulting Bayesian dilemma. In concert with effect size and replication intervals, P rep provides all of the information now used in evaluating research, while avoiding many of the pitfalls of traditional statistical inference.
Live Cell Imaging: Assessing the Phototoxicity of 488 and 546 nm Light and Methods to Alleviate it

In live cell imaging of fluorescent proteins, phototoxicity of the excitation light can be problematical. Cell death is obvious, but reduced cell viability can make the interpretation of observations error prone. We characterized the phototoxic consequences of 488 and 546 nm light on untransformed human cells and tested methods that have or could be used to alleviate photodamage. Unlabeled RPE1 cells were given single 0.5–2.5 min irradiations in early G1 from a mercury arc lamp on a fluorescence microscope. Four hundred eighty‐eight nanometer light produced a dose‐dependent decrease in the percentage of cells that progressed to mitosis, slowing of the cell cycle for some of those entering mitosis, and a ∼12% incidence of cell death for the highest dose. For 546 nm light we found a 10–15% reduction in the percentage of cells entering mitosis, no strong dose dependency, and a ∼2% incidence of cell death for the longest irradiations. For cells expressing GFP‐centrin1 or mCherry‐centrin1, fewer entered mitosis for each dose than unlabeled cells. For constant total dose 488 nm light irradiations of unlabeled cells, reducing the intensity 10‐fold or spreading the exposures out as a series of 10 sec pulses at 1 min intervals produced a minor and not consistent improvement in the percentage of cells entering mitosis. Reducing oxidative processes, by culturing at ∼3% oxygen or adding the reducing agent Trolox noticeably increased the fraction of cells entering mitosis. Thus, for long‐term imaging there can be value to using RFP constructs and for GFP‐tagged proteins reducing oxidative processes. J. Cell. Physiol. 232: 2461–2468, 2017. © 2016 Wiley Periodicals, Inc.
The RAM Enhanced Disk Cache Project (REDCAP)

This paper presents the RAM enhanced disk cache project, REDCAP, a new cache of disk blocks which reduces the read I/O time by using a small portion of the main memory. The essential ideas behind REDCAP are to enlarge the built-in cache of the disk drive, imitate its behavior, and take advantage of its read-ahead mechanism by prefetching disk blocks. REDCAP is intended to be I/O- time efficient, and implements an activation-deactivation algorithm which turns its cache on and off dynamically depending on the I/O time improvement achieved. REDCAP has been implemented in the Linux kernel. The experimental results show that our proposal reduces the application time by up to 80% for workloads which exhibit some spatial locality, while it has the same performance as a traditional system for those workloads which have a random access pattern, or perform large sequential reads.
Computer animation of human walking: a survey

This paper surveys the set of techniques developed in Computer Graphics for animating human walking. We first focus on the evolution from purely kinematic «knowledge-based" methods to approaches that incorporate dynamics constraints, or use dynamics simulations to generate motion. We lastly review the recent advances on motion editing, that enable the control of complex animations by interactively blending and tuning synthetic or captured motions.
CORIANDER ANAPHYLAXIS IN A SPICE GRINDER WITH UNDETECTED OCCUPATIONAL ALLERGY

Abstract Background: Anaphylaxis after ingestion of spices as a result from occupational sensitization remains anecdotal. We describe a patient, working in a spice factory, with anaphylaxis from coriander in a meal. He also demonstrated urticaria, angio-edema, rhinoconjunctivitis and bronchospasm during handling coriander and fenugreek. Objective: To determine the mechanism of the anaphylactic reaction and to evaluate cross-reactivity between both botanically unrelated spices. Methods: Investigations comprised quantification of total and specific IgE by Immuno-CAP FEIA, skin testing, basophil activation experiments by flow-assisted determination of CD63 expression in the patient and 3 healthy controls. Immuno-CAP inhibition experiments were applied to investigate cross-reactivity. Results: Specific IgE, skin tests and basophil activation tests were clearly positive in the patient, whereas they remained negative in controls. No cross-reactivity between fenugreek and coriander was demonstrable by inhibition experiments. Conclusions: The clinical manifestations in temporal relationship to ingestion of coriander and handling of coriander and/or fenugreek, the positive specific IgE results, skin tests and basophil activation assays support the diagnosis of allergy to both spices. History suggests sensitization by occupational exposure.
Physical Activity and Colon Cancer Risk among Women in the California Teachers Study

Background: Existing data suggest that physical activity reduces colon cancer risk, but the association is not consistently observed in women. One potential explanation for this inconsistency is that hormone therapy, which is associated with lower colon cancer risk, acts as a modifier of the physical activity/colon cancer relationship. Methods: Participants in the California Teachers Study (N = 120,147), a prospective cohort of female teachers and administrators residing in California, ages 22 to 84 years at baseline and with no prior history of colon cancer were eligible for study. Between 1996 and 2002, 395 patients were diagnosed with invasive colon cancer. The relative risks (RR) associated with lifetime (high school through age 54 years or current age) and recent (past 3 years) strenuous and moderate recreational physical activity were estimated using Cox proportional hazards regression models. Results: Combined lifetime moderate and strenuous recreational physical activity was only modestly associated with colon cancer risk in the cohort [≥4 versus ≤0.5 h/wk/y: RR, 0.75; 95% confidence interval, 0.57-1.00; Ptrend = 0.23]. Lifetime physical activity reduced colon cancer risk among postmenopausal women who had never taken hormone therapy (≥4 versus ≤0.5 h/wk/y: RR, 0.51; 95% confidence interval, 0.31-0.85; Ptrend = 0.02). Postmenopausal women with histories of hormone therapy use had lower colon cancer risk, but their risk was not associated with physical activity. The likelihood ratio test for interaction between hormone use and lifetime moderate plus strenuous physical activity was of borderline statistical significance (P = 0.05). We observed no effect modification by age, body mass index, smoking status, menopausal status, or folate intake. Conclusions: Lifetime recreational physical activity may protect against colon cancer among postmenopausal women who have never used hormone therapy. Among hormone therapy users, who have lower risk of colon cancer, recreational physical activity does not seem to provide any additional benefit. With declining rates of hormone therapy use, physical activity offers one possible means for reducing women's colon cancer risk. (Cancer Epidemiol Biomarkers Prev 2007;16(3):517–25)
