Young Adults' Retrospective Reports of Childhood Television Viewing

Two studies investigated young adults' retrospective reports of childhood television viewing patterns. Prime-time TV schedules from several years prior to the assessment were presented to participants, who indicated how often they watched each program. Validity of the reports was assessed by examining the logical consistency in the reported patterns and measuring participants' recall of content from programs they reported to have watched often, occasionally, or never. As predicted, participants reported ecologically valid patterns of TV viewing and recalled more content from frequently viewed programs than from ones viewed less frequently. Accuracy of recalled content was very high. Test-retest reliability indicated very high consistency in TV-viewing reports across one week. Past overall viewing levels were related to a current measure of perceived realism in TV programs, indicating nomological validity of the measure. The discussion includes implications of a retrospective measure of early TV viewing for research on relationships between early media exposure and later psychological characteristics.
VEGF‐C Induces Lymphangiogenesis and Angiogenesis in the Rat Mesentery Culture Model

Lymphatic and blood microvascular systems are critical for tissue function. Insights into the coordination of both systems can be gained by investigating the relationships between lymphangiogenesis and angiogenesis. Recently, our laboratory established the rat mesentery culture model as a novel tool to investigate multicellular interactions during angiogenesis in an intact microvascular network scenario. The objective of this study was to determine whether the rat mesentery culture model can be used to study lymphangiogenesis.
Comparison of PIN- and pattern-based behavioral biometric authentication on mobile devices

Personal identification numbers (PIN) and unlock patterns are highly popular authentication mechanisms on smart mobile devices but they are not sufficiently secure. PIN or pattern mechanisms enhanced by additional, implicit behavioral biometric authentication can offer stronger authentication assurance while preserving usability, therefore becoming very attractive. Individual studies on PIN- and pattern-based behavioral biometric authentication on smartphones were conducted but their results cannot be directly compared. In this work, we present a comparison study on the authentication accuracy between PIN-based and pattern-based behavioral biometric authentication using both smartphone and tablet. We developed a uniform framework for both PIN-based and pattern-based schemes and used two representative methods-Histogram and DTW-for user verification. We recruited 15 users and collected behavioral biometric data for both simple and complex PINs and patterns. Our experimental results show that PIN-based and pattern-based behavioral biometric authentication schemes can achieve about the same level of accuracy but not all verification methods are equal. The Histogram method can achieve more consistent results and handle template aging better than the DTW method based on our results. Our findings are expected to shed light on the exploration and analysis of effective behavioral biometric verification methods and facilitate more comprehensive investigation on behavioral biometric authentication for mobile devices.
Occupational demands and health effects for bricklayers and construction supervisors: A systematic review.

BACKGROUND knowledge was gathered on occupational demands and health effects of two occupations in the construction industry, bricklayers and supervisors, in order to design a job-specific workers' health surveillance (WHS) for construction workers. METHODS we systematically searched MEDLINE, EMBASE, PsycINFO, HSELINE, NIOSHTIC-2, and Picarta up to December 2008. RESULTS a total of 60 articles were included. Evidence was found for the following demands for bricklayers: energetic load (exceeding 25% heart rate reserve), load on the lower back (exceeding the NIOSH-threshold value of 3.4 kN), repetitive force exertions of the upper extremities, frequent bending with trunk flexion exceeding 60° and working with the arms more than 60° elevated. Environmental demands include: dust and quartz exposure (exceeding the limit values of 3.0 and 0.05 mg/m(3), respectively), vibration and noise (exceeding the limit value of 80 dBA). Bricklayers are at increased risk of lung cancer, low back pain, complaints of arms and legs and getting injuries. Among construction supervisors are walking and standing common physically demanding activities. Psychosocial demands with evidence for supervisors were mental demands, workload, time pressure, working long hours, and social-organizational factors. Supervisors are at increased risk of lung cancer and injuries. CONCLUSIONS for bricklayers evidence was found for physical demands and risk on low back pain and complaints of arms and legs, for construction supervisors on psychosocial demands. Both occupations are at increased risk of lung cancer and injuries. Job-specific demands and health effects should be incorporated in WHS for construction workers.
Influence of Antibiotic Selection on Genetic Composition of Escherichia coli Populations from Conventional and Organic Dairy Farms

ABSTRACT The widespread agricultural use of antimicrobials has long been considered a crucial influence on the prevalence of resistant genes and bacterial strains. It has been suggested that antibiotic applications in agricultural settings are a driving force for the development of antimicrobial resistance, and epidemiologic evidence supports the view that there is a direct link between resistant human pathogens, retail produce, farm animals, and farm environments. Despite such concerns, little is understood about the population processes underlying the emergence and spread of antibiotic resistance and the reversibility of resistance when antibiotic selective pressure is removed. In this study, hierarchical log-linear modeling was used to assess the association between farm type (conventional versus organic), age of cattle (calf versus cow), bacterial phenotype (resistant versus susceptible), and the genetic composition of Escherichia coli populations (E. coli Reference Collection [ECOR] phylogroup A, B1, B2, or D) among 678 susceptible and resistant strains from a previously published study of 60 matched dairy farms (30 conventional and 30 organic) in Wisconsin. The analysis provides evidence for clonal resistance (ampicillin resistance) and genetic hitchhiking (tetracycline resistance [Tetr]), estimated the rate of compositional change from conventional farming to organic farming (mean, 8 years; range, 3 to 15 years), and discovered a significant association between low multidrug resistance, organic farms, and strains of the numerically dominant phylogroup B1. These data suggest that organic farming practices not only change the frequency of resistant strains but also impact the overall population genetic composition of the resident E. coli flora. In addition, the results support the hypothesis that the current prevalence of Tetr loci on dairy farms has little to do with the use of this antibiotic.
Factors affecting stroking patterns and body angle in diving Weddell seals under natural conditions

SUMMARY Aquatic animals use a variety of strategies to reduce the energetic cost of locomotion. Efficient locomotion is particularly important for breath-holding divers because high levels of exercise may quickly deplete oxygen reserves, leading to the termination of a dive. We investigated the swimming behavior of eight adult Weddell seals, which are proficient divers, in McMurdo Sound, Antarctica. A newly developed data logger was attached to free-ranging females at their own breeding sites to record swimming speed, depth, two-dimensional accelerations (stroke frequency and body angle) and temperature. All seals conducted multiple deep dives (the mean dive depth range for each animal was 223.3±66.5–297.9±164.7 m). Prolonged gliding while descending was observed with thinner females (N=5 seals). But the fatter females (N=3 seals) exhibited only swim-and-glide swimming, characterized by intermittent stroking and fluctuating swim speed, throughout their descent and ascent. The body angles of four of the seals were restricted to less than 30° by the location of breathing holes in the ice and the slope of local bathymetric features. Of these four, the three fatter seals adopted the stroke-and-glide method while the other thinner seal descended with prolonged periods of gliding. Prolonged gliding seems to be a more efficient method for locomotion because the surface time between dives of gliding seals was significantly less than that of stroking animals, despite their same stroke frequencies.
Quantifying the association between habitual energy expenditure and blood pressure.

BACKGROUND Previous studies have demonstrated an association between physical inactivity and hypertension, but the methods used to assess activity have been subjective and imprecise. Recently methods have become available allowing measurement of energy expenditure in free-living populations. Our aim was to employ these methods to assess the independent association between energy expenditure, cardio-respiratory fitness and blood pressure. METHODS In a cross-sectional study of 775 people (45-70 years) participating in a continuing population-based cohort study, energy expenditure was assessed by 4 days of heart rate monitoring with individual calibration of the relationship between heart rate and energy expenditure, a method validated against doubly-labelled water and whole body calorimetry. Cardio-respiratory fitness was assessed in a sub-maximal test. To adjust for measurement error in the assessment of usual energy expenditure and fitness, 190 subjects repeated both tests on three further occasions at 4-monthly intervals. RESULTS A highly significant linear trend in blood pressure was found across quintiles of the physical activity level, the ratio of total energy expenditure to basal metabolic rate. The differences in the mean systolic/diastolic blood pressure between the top and bottom quintile was 6.3/4.4 mmHg in men and 10.7/5.9 mmHg in women. These effects were independent of obesity and cardio-respiratory fitness. Correction for measurement error suggests that the true underlying relationship between usual energy expenditure and blood pressure is stronger still. CONCLUSIONS These findings are compatible with a strong association between usual energy expenditure and blood pressure and support public health strategies aimed at increasing overall energy expenditure.
Room-temperature single-electron transfer and detection with silicon nanodevices

Transfer and subsequent detection of single electrons are demonstrated at room temperature using a silicon-on-insulator nanodevice. The turnstile, which is composed of two Si-wire-FETs with a fine gate, enables us to transfer single electrons by opening and closing the two FETs alternately. The transferred individual electrons are stored in a single-electron box and detected by the electrometer with single-electron resolution. The present device achieves high-speed transfer and long retention.
Query Adaptive Fusion for Graph-Based Visual Reranking

Developing effective fusion schemes for multiple feature types has always been a hot issue in content-based image retrieval. In this paper, we propose a novel method for graph-based visual reranking, which addresses two major limitations in existing methods. First, in the phase of graph construction, our method introduces fine-grained measurements for image relations, by assigning the edge weights using normalized similarity. Furthermore, in the phase of graph fusion, rather than summing up all the graphs for different single features indiscriminately, we propose to estimate the reliability of each feature through a statistical model, and selectively fuse the single graphs via query-adaptive fusion weights. Fusion methods with either labeled data and unlabeled data are proposed and the performance are evaluated and compared by experiments. Our method is evaluated on five public datasets, by fusing scale-invariant feature transform (SIFT), CNN, and hue, saturation, hue (HSV), three complementary features. Experimental results demonstrate the effectiveness of the proposed method, which yields superior results than the competing methods.
An improved through line de-embedding method with even-odd mode measurement

This paper presents a new S-parameter matrix calculation based de-embedding methodology. In this method, a noval even-odd mode measurement is proposed to correct the error in traditional through line de-embedding methodology. The influence of the asymmetric input and output stub is canceled. A comparison of the different de-embedding methods for active device (0.7 μm InP DHBT) are performed up to 66 GHz, the results showed that the proposed method has good accuracy and suitable for millimeter-wave (mmWave).
l7Rn6 Encodes a Novel Protein Required for Clara Cell Function in Mouse Lung Development

The highly secretory Clara cells play a pivotal role in protecting the lung against inflammation and oxidative stress. This study reports the positional cloning of a novel protein required for Clara cell physiology in mouse lung development. The perinatal lethal N-ethyl-N-nitrosourea-induced l7Rn64234SB allele contained a nonsense mutation in the previously hypothetical gene NM_026304 on chromosome 7. Whereas l7Rn6 mRNA levels were indistinguishable from wild type, l7Rn64234SB homozygotes exhibited decreased expression of the truncated protein, suggesting protein instability. During late gestation, l7Rn6 was widely expressed in the cytoplasm of lung epithelial cells, whereas perinatal expression was restricted to the bronchiolar epithelium. Homozygosity for the l7Rn64234SB allele did not affect early steps in lung patterning, growth, or cellular differentiation. Rather, mutant lungs demonstrated severe emphysematous enlargement of the distal respiratory sacs at birth. Clara cell pathophysiology was evident from decreased cytoplasmic CCSP and SP-B protein levels, enlargement and disorganization of the Golgi complex, and formation of aberrant vesicular structures. Additional support for a role in the secretory pathway derived from l7Rn6 localization to the endoplasmic reticulum. Thus, l7Rn6 represents a novel protein required for organization and/or function of the secretory apparatus in Clara cells in mouse lung.
Intracellular Segregation of Phosphatidylinositol-3,4,5-Trisphosphate by Insulin-Dependent Actin Remodeling in L6 Skeletal Muscle Cells

ABSTRACT Insulin stimulates glucose uptake by recruiting glucose transporter 4 (GLUT4) from an intracellular pool to the cell surface through a mechanism that is dependent on phosphatidylinositol (PI) 3-kinase (PI3-K) and cortical actin remodeling. Here we test the hypothesis that insulin-dependent actin filament remodeling determines the location of insulin signaling molecules. It has been shown previously that insulin treatment of L6 myotubes leads to a rapid rearrangement of actin filaments into submembrane structures where the p85 regulatory subunit of PI3-K and organelles containing GLUT4, VAMP2, and the insulin-regulated aminopeptidase (IRAP) colocalize. We now report that insulin receptor substrate-1 and the p110α catalytic subunit of PI3-K (but not p110β) also colocalize with the actin structures. Akt-1 was also found in the remodeled actin structures, unlike another PI3-K effector, atypical protein kinase C λ. Transiently transfected green fluorescent protein (GFP)-tagged pleckstrin homology (PH) domains of general receptor for phosphoinositides-1 (GRP1) or Akt (ligands of phosphatidylinositol-3,4,5-trisphosphate [PI-3,4,5-P3]) migrated to the periphery of the live cells; in fixed cells, they were detected in the insulin-induced actin structures. These results suggest that PI-3,4,5-P3 is generated on membranes located within the actin mesh. Actin remodeling and GLUT4 externalization were blocked in cells highly expressing GFP-PH-GRP1, suggesting that PI-3,4,5-P3 is required for both phenomena. We propose that PI-3,4,5-P3 leads to actin remodeling, which in turn segregates p85α and p110α, thus localizing PI-3,4,5-P3 production on membranes trapped by the actin mesh. Insulin-stimulated actin remodeling may spatially coordinate the localized generation of PI-3,4,5-P3 and recruitment of Akt, ultimately leading to GLUT4 insertion at the plasma membrane.
A note on estimating the posterior density of a quantitative trait locus from a Markov chain Monte Carlo sample

We provide an overview of the use of kernel smoothing to summarize the quantitative trait locus posterior distribution from a Markov chain Monte Carlo sample. More traditional distributional summary statistics based on the histogram depend both on the bin width and on the sideway shift of the bin grid used. These factors influence both the overall mapping accuracy and the estimated location of the mode of the distribution. Replacing the histogram by kernel smoothing helps to alleviate these problems. Using simulated data, we performed numerical comparisons between the two approaches. The results clearly illustrate the superiority of the kernel method. The kernel approach is particularly efficient when one needs to point out the best putative quantitative trait locus position on the marker map. In such situations, the smoothness of the posterior estimate is especially important because rough posterior estimates easily produce biased mode estimates. Different kernel implementations are available from Rolf Nevanlinna Institute’s web page (http://www.rni.helsinki.fi/˜fjh). Genet. Epidemiol. 22:369–376, 2002. © 2002 Wiley‐Liss, Inc.
Theoretical Study of Metal-Insulator-Metal Tunneling Diode Figures of Merit

The performance of metal-insulator-metal (MIM) diodes is investigated. In this paper, we derive an analytical model that uses the Transfer Matrix Method based on the Airy Functions (AF-TMM) for the tunneling transmission probability through any number of insulating layers. The fast-computing AF-TMM simulator results show a complete matching with the numerical Non-Equilibrium Green's Function and a reasonable matching with previously published experimental results. This study shows the effect of the work function difference and insulator thickness on MIM diode performance. The advantage of using two insulator layers on enhancing the diode responsivity, resistance, and nonlinearity is also investigated.
Matrice de dépendances enrichie

Les matrices de dependance (DSM - Dependency Structure Matrix), developpees dans le cadre de l'optimisation de processus, ont fait leurs preuves pour identifier les dependances logicielles entre des packages ou des sous-syste- mes. Il existe plusieurs algorithmes pour structurer une matrice de facon a ce qu'elle reflete l'architecture des elements analyses et mette en evidence des cycles entre les sous-systemes. Cependant, les implementations de matrices de dependance existantes manquent d'informations importantes pour apporter une reelle aide au travail de reingenierie. Par exemple, le poids des relations qui posent probleme ainsi que leur type ne sont pas clairement presentes. Ou en- core, des cycles independants sont fusionnes. Il est egalement difficile d'obtenir une visualisation centree sur un package. Dans ce papier, nous ameliorons les matrices de dependance en ajoutant des informations sur (i) le type de refe- rences, (ii) le nombre d'entites referencantes, (iii) le nombre d'entites referen- cees. Nous distinguons egalement les cycles independants. Ce travail a ete im- plemente dans l'environnement de reingenierie open-source Moose. Il a ete ap- plique a des etudes de cas complexes comme le framework Morphic UI contenu dans les environnements Smalltalk open-source Squeak et Pharo. Les resultats obtenus ont ete appliques dans l'environnement de programmation Pharo et ont mene a des ameliorations.
Improving the energy efficiency of street lighting. A case in the South of Spain

One of the objectives of the electricity market is to reduce energy demand, through efficient use. The street lighting sector is one of more consumption and less efficient. In recent years, many countries are promoting action plans to promote the reduction of energy consumption and pollutant gas. This paper analyzes the potential savings from outdoor lighting installations. Also, the different lighting systems and technologies are described, and the measures to be taken for energy savings, increasing the quality of the street light. Finally, a technical-economic solution is raised to renovate inefficient installations, through the incorporation of Energy Service Companies.

Simulation results on a set of mathematical functions with the fuzzy bat algorithm outperform the traditional bat algorithm and genetic algorithms.
Geo word clouds

Word clouds are a popular method to visualize the frequency of words in textual data. Nowadays many text-based data sets, such as Flickr tags, are geo-referenced, that is, they have an important spatial component. However, existing automated methods to generate word clouds are unable to incorporate such spatial information. We introduce geo word clouds: word clouds which capture not only the frequency but also the spatial relevance of words. Our input is a set of locations from one (or more) geographic regions with (possibly several) text labels per location. We aggregate word frequencies according to point clusters and employ a greedy strategy to place appropriately sized labels without overlap as close as possible to their corresponding locations. While doing so we "draw" the spatial shapes of the geographic regions with the corresponding labels. We experimentally explore trade-offs concerning the location of labels, their relative sizes and the number of spatial clusters. The resulting word clouds are visually pleasing and have a low error in terms of relative scaling and locational accuracy of words, while using a small number of clusters per label.
MECAT: an ultra-fast mapping, error correction and de novo assembly tool for single-molecule sequencing reads

The high computational cost of current assembly methods for the long, noisy single molecular sequencing (SMS) reads has prevented them from assembling large genomes. We introduce an ultra-fast alignment method based on a novel global alignment score. For large human SMS data, our method is 7X faster than MHAP for pairwise alignment and 15X faster than BLASR for reference mapping. We develop a Mapping, Error Correction and de novo Assembly Tool (MECAT) by integrating our new alignment and error correction methods, with the Celera Assembler. MECAT is capable of producing high quality de novo assembly of large genome from SMS reads with low computational cost. MECAT produces reference-quality assemblies of Saccharomyces cerevisiae, Arabidopsis thaliana, Drosophila melanogaster and reconstructs the human CHM1 genome with 15% longer NG50 in only 7600 CPU core hours using 54X SMS reads and a Chinese Han genome in 19200 CPU core hours using 102X SMS reads.
