    Data reproducibility is a critical issue in all scientific experiments. In this manuscript, the problem of quantifying the reproducibility of graphical measurements is considered. The image intra-class correlation coefficient (I2C2) is generalized and the graphical intra-class correlation coefficient (GICC) is proposed for such purpose. The concept for GICC is based on multivariate probit-linear mixed effect models. A Markov Chain Monte Carlo EM (mcm-cEM) algorithm is used for estimating the GICC. Simulation results with varied settings are demonstrated and our method is applied to the KIRBY21 test-retest dataset. PMID:26190878

  8. Quantifying the reliability of image replication studies: the image intraclass correlation coefficient (I2C2).

    This article proposes the image intraclass correlation (I2C2) coefficient as a global measure of reliability for imaging studies. The I2C2 generalizes the classic intraclass correlation (ICC) coefficient to the case when the data of interest are images, thereby providing a measure that is both intuitive and convenient. Drawing a connection with classical measurement error models for replication experiments, the I2C2 can be computed quickly, even in high-dimensional imaging studies. A nonparametric bootstrap procedure is introduced to quantify the variability of the I2C2 estimator. Furthermore, a Monte Carlo permutation is utilized to test reproducibility versus a zero I2C2, representing complete lack of reproducibility. Methodologies are applied to three replication studies arising from different brain imaging modalities and settings: regional analysis of volumes in normalized space imaging for characterizing brain morphology, seed-voxel brain activation maps based on resting-state functional magnetic resonance imaging (fMRI), and fractional anisotropy in an area surrounding the corpus callosum via diffusion tensor imaging. Notably, resting-state fMRI brain activation maps are found to have low reliability, ranging from .2 to .4. Software and data are available to provide easy access to the proposed methods.

  9. Efficient design of cluster randomized and multicentre trials with unknown intraclass correlation.

    For cluster randomized and multicentre trials evaluating the effect of a treatment on persons nested within clusters, equations have been published to compute the optimal sample sizes at the cluster and person level as a function of sampling costs and intraclass correlation (ICC). Here, optimal means maximum power and precision for a given sampling budget, or minimum sampling costs for a given power and precision. However, the ICC is usually unknown, and the optimal sample sizes depend strongly on this ICC. To overcome this local optimality problem, this study presents Maximin designs (MMDs) based on relative efficiency (RE) and efficiency. These designs perform well over a range of possible ICC values either in terms of RE compared with the locally optimal designs, or in terms of minimum efficiency (maximum variance) of the treatment effect estimator. The use of MMDs is illustrated using information from many cluster randomized trials in primary care. It is concluded that MMDs and the optimal design for an ICC halfway its assumed range are efficient for a range of ICC values and recommendable for practical use. This requires that trial reports mention the study cost per cluster and person. PMID:21937473

    Least squares analyses (e.g., ANOVAs, linear regressions) of hierarchical data leads to Type-I error rates that depart severely from the nominal Type-I error rate assumed. Thus, when least squares methods are used to analyze hierarchical data coming from designs in which some groups are assigned to the treatment condition, and others to the control condition (i.e., the widely used “groups nested under treatment” experimental design), the Type-I error rate is seriously inflated, leading too often to the incorrect rejection of the null hypothesis (i.e., the incorrect conclusion of an effect of the treatment). To highlight the severity of the problem, we present simulations showing how the Type-I error rate is affected under different conditions of intraclass correlation and sample size. For all simulations the Type-I error rate after application of the popular Kish (1965) correction is also considered, and the limitations of this correction technique discussed. We conclude with suggestions on how one should collect and analyze data bearing a hierarchical structure. PMID:21687445

  15. Sample size calculation for treatment effects in randomized trials with fixed cluster sizes and heterogeneous intraclass correlations and variances.

    2015-10-01

    When comparing two different kinds of group therapy or two individual treatments where patients within each arm are nested within care providers, clustering of observations may occur in both arms. The arms may differ in terms of (a) the intraclass correlation, (b) the outcome variance, (c) the cluster size, and (d) the number of clusters, and there may be some ideal group size or ideal caseload in case of care providers, fixing the cluster size. For this case, optimal cluster numbers are derived for a linear mixed model analysis of the treatment effect under cost constraints as well as under power constraints. To account for uncertain prior knowledge on relevant model parameters, also maximin sample sizes are given. Formulas for sample size calculation are derived, based on the standard normal as the asymptotic distribution of the test statistic. For small sample sizes, an extensive numerical evaluation shows that in a two-tailed test employing restricted maximum likelihood estimation, a safe correction for both 80% and 90% power, is to add three clusters to each arm for a 5% type I error rate and four clusters to each arm for a 1% type I error rate.

    Objectives Measuring the intraclass correlation coefficient (ICC) and design effect (DE) may help to modify the public health interventions for body mass index (BMI), physical activity and diet according to geographic targeting of interventions in different countries. The purpose of this study was to quantify the level of clustering and DE in BMI, physical activity and diet in 56 low-income, middle-income and high-income countries. Design Cross-sectional study design. Setting Multicountry national survey data. Methods The World Health Survey (WHS), 2003, data were used to examine clustering in BMI, physical activity in metabolic equivalent of task (MET) and diet in fruits and vegetables intake (FVI) from low-income, middle-income and high-income countries. Multistage sampling in the WHS used geographical clusters as primary sampling units (PSU). These PSUs were used as a clustering or grouping variable in this analysis. Multilevel intercept only regression models were used to calculate the ICC and DE for each country. Results The median ICC (0.039) and median DE (1.82) for BMI were low; however, FVI had a higher median ICC (0.189) and median DE (4.16). For MET, the median ICC was 0.141 and median DE was 4.59. In some countries, however, the ICC and DE for BMI were large. For instance, South Africa had the highest ICC (0.39) and DE (11.9) for BMI, whereas Uruguay had the highest ICC (0.434) for MET and Ethiopia had the highest ICC (0.471) for FVI. Conclusions This study shows that across a wide range of countries, there was low area level clustering for BMI, whereas MET and FVI showed high area level clustering. These results suggested that the country level clustering effect should be considered in developing preventive approaches for BMI, as well as improving physical activity and healthy diets for each country.

  1. Intraclass correlation coefficients for cluster randomized trials in care pathways and usual care: hospital treatment for heart failure

    PubMed Central

    2014-01-01

    Background Cluster randomized trials are increasingly being used in healthcare evaluation to show the effectiveness of a specific intervention. Care pathways (CPs) are becoming a popular tool to improve the quality of health-care services provided to heart failure patients. In order to perform a well-designed cluster randomized trial to demonstrate the effectiveness of Usual care (UC) and CP in heart failure treatment, the intraclass correlation coefficient (ICC) should be available before conducting a trial to estimate the required sample size. This study reports ICCs for both demographical and outcome variables from cluster randomized trials of heart failure patients in UC and care pathways. Methods To calculate the degree of within-cluster dependence, the ICC and associated 95% confidence interval were calculated by a method based on analysis of variance. All analyses were performed in R software version 2.15.1. Results ICCs for baseline characteristics ranged from 0.025 to 0.058. The median value and interquartile range was 0.043 [0.026-0.052] for ICCs of baseline characteristics. Among baseline characteristics, the highest ICCs were found for admission by referral or admission from home (ICC = 0.058) and the disease severity at admission (ICC = 0.046). Corresponding ICCs for appropriateness of the stay, length of stay and hospitalization cost were 0.069, 0.063, and 0.001 in CP group and 0.203, 0.020, 0.046 for usual care, respectively. Conclusion Reported values of ICCs from present care pathway trial and UC results for some common outcomes will be helpful for estimating sample size in future clustered randomized heart failure trials, in particular for the evaluation of care pathways.

    Test-retest reliability of neuroimaging measurements is an important concern in the investigation of cognitive functions in the human brain. To date, intraclass correlation coefficients (ICCs), originally used in inter-rater reliability studies in behavioral sciences, have become commonly used metrics in reliability studies on neuroimaging and functional near-infrared spectroscopy (fNIRS). However, as there are six popular forms of ICC, the adequateness of the comprehensive understanding of ICCs will affect how one may appropriately select, use, and interpret ICCs toward a reliability study. We first offer a brief review and tutorial on the statistical rationale of ICCs, including their underlying analysis of variance models and technical definitions, in the context of assessment on intertest reliability. Second, we provide general guidelines on the selection and interpretation of ICCs. Third, we illustrate the proposed approach by using an actual research study to assess intertest reliability of fNIRS-based, volumetric diffuse optical tomography of brain activities stimulated by a risk decision-making protocol. Last, special issues that may arise in reliability assessment using ICCs are discussed and solutions are suggested.

    1999-02-01

    The Hilbert transform is used to extract the amplitude modulation signals for the intraseasonal variation of Length of Day ranging from 1962 to 1996. The results reveal that the intraseasonal Length of Day amplitude modulation variation has not only a positive secular trend, but also an interannual variation which is ahead of the ENSO evolution. The amplitude modulations for the about 50-day oscillation and the about 120-day oscillation have been studied separately. This shows that the peaks of the approximately 50-day oscillation amplitude modulation always occur longer than one year before the appearance of each ENSO event. They also indicate the dominant correspondence between the about 120-day oscillation amplitude modulation and ENSO events since 1976 and the absolutely negative correlation with ENSO before 1972 because of phase change of 180 degrees in the evolution of the about 120-day oscillation amplitude modulation time series at the beginning of the 1970's.

    2006-02-01

    Electrical conductivity (EC) of milk is an indicator of mastitis. If EC shows genetic variation and is genetically correlated to mastitis, it could be used in a breeding program that includes selection for improved mastitis resistance. In this study, daily records of EC and mastitis from about 1,500 Holstein cows were analyzed. A bivariate animal model was used for estimation of (co)variance components, including fixed effects of age of calving, herd-test-day, and days in milk, in addition to random additive genetic effects and permanent environmental effects. For EC, the estimated heritability was moderate (0.22 to 0.39), whereas for mastitis, the heritability was low (0.013). The genetic correlation between EC and mastitis was estimated to be 0.75, and genetic improvement of mastitis resistance should be feasible through selection for reduced EC. PMID:16428645

    The hypocretin/orexin neuropeptides (hcrt) are key players in the control of sleep and wakefulness evidenced by the fact that lack of hcrt leads to the sleep disorder Narcolepsy Type 1. Sleep disturbances are common in mood disorders, and hcrt has been suggested to be poorly regulated in depressed subjects. To study seasonal variation in hcrt levels, we obtained data on hcrt-1 levels in the cerebrospinal fluid (CSF) from 227 human individuals evaluated for central hypersomnias at a Danish sleep center. The samples were taken over a 4 year timespan, and obtained in the morning hours, thus avoiding impact of the diurnal hcrt variation. Hcrt-1 concentration was determined in a standardized radioimmunoassay. Using biometric data and sleep parameters, a multivariate regression analysis was performed. We found that the average monthly CSF hcrt-1 levels varied significantly across the seasons following a sine wave with its peak in the summer (June-July). The amplitude was 19.9 pg hcrt/mL [12.8-26.9] corresponding to a 10.6% increase in midsummer compared to winter. Factors found to significantly predict the hcrt-1 values were day length, presence of snow, and proximity to the Christmas holiday season. The hcrt-1 values from January were much higher than predicted from the model, suggestive of additional factors influencing the CSF hcrt-1 levels such as social interaction. This study provides evidence that human CSF hcrt-1 levels vary with season, correlating with day length. This finding could have implications for the understanding of winter tiredness, fatigue, and seasonal affective disorder. This is the first time a seasonal variation of hcrt-1 levels has been shown, demonstrating that the hcrt system is, like other neurotransmitter systems, subjected to long term modulation.

    OBJECTIVES: To estimate the prevalence and correlates of dementia at death and to assess the usefulness of death certificate data in the reporting of dementia. METHODS: The authors analyzed next-of-kin interviews for 599 male and 628 female decedents using data from the National Institute on Aging's Survey of the Last Days of Life. RESULTS: Death certificate data in this population show the prevalence of dementia to be less than 1%, consistent with previous reports based on death certificates but a substantial underestimate compared to the 11.9% reported in a national survey. Using a dementia index based on the informant's report of whether the decedent had been diagnosed with a dementing illness and the extent of her or his cognitive and functional limitations, this study found a prevalence of dementia of 8.5%. A high score on the dementia index was significantly associated with older age, Parkinson's disease, and incontinence. Lower relative odds for dementia at death were found for people with either a lifetime history or a death certificate report of cancer. Similarly, people with a lifetime history of coronary heart disease were found to have lower relative odds for dementia at death. CONCLUSION: These results suggest that informant interviews may be a useful source of data to examine factors associated with dementia and to estimate the prevalence of dementia in the last year of life.

    2007-02-01

    As the size of the available collections of 3D objects grows, database transactions become essential for their management with the key operation being retrieval (query). Large collections are also precategorized into classes so that a single class contains objects of the same type (e.g., human faces, cars, four-legged animals). It is shown that general object retrieval methods are inadequate for intraclass retrieval tasks. We advocate that such intraclass problems require a specialized method that can exploit the basic class characteristics in order to achieve higher accuracy. A novel 3D object retrieval method is presented which uses a parameterized annotated model of the shape of the class objects, incorporating its main characteristics. The annotated subdivision-based model is fitted onto objects of the class using a deformable model framework, converted to a geometry image and transformed into the wavelet domain. Object retrieval takes place in the wavelet domain. The method does not require user interaction, achieves high accuracy, is efficient for use with large databases, and is suitable for nonrigid object classes. We apply our method to the face recognition domain, one of the most challenging intraclass retrieval tasks. We used the Face Recognition Grand Challenge v2 database, yielding an average verification rate of 95.2 percent at 10-3 false accept rate.

  19. PHYSICS OF OUR DAYS: Cosmic microwave background anisotropy data correlation in WMAP and Relikt-1 experiments

    NASA Astrophysics Data System (ADS)

    Skulachev, Dmitrii P.

    2010-07-01

    A comparison is made of cosmic microwave background anisotropy data obtained from the WMAP satellite in 2001 - 2006 and from the Relikt-1 satellite in 1983 - 1984. It is shown that low-temperature area found by Relikt-1 is the location of the 'coldest spot' of the WMAP radiomap. The mutual correlation of the two datasets is estimated and found to be positive for all sky regions surveyed. The conclusion is made that with the 98% probability, the Relikt-1 experiment had detected the same signal that was later identified by WMAP. A discussion is given of whether the Relikt-1 experiment parameters were chosen correctly.

  20. Global Characteristics of the Correlation and Time Lag Between Solar and Ionospheric Parameters in the 27-day Period

    The 27-day variations of topside ionosphere are investigated using the in-situ electron density measurements from the CHAMP planar Langmuir probe and GRACE K-band ranging system. As the two satellite systems orbit at the altitudes of approx. 370 km and approx. 480 km, respectively, the satellite data sets are greatly valuable for examining the electron density variations in the vicinity of F2-peak. In a 27-day period, the electron density measurements from the satellites are in good agreements with the solar flux, except during the solar minimum period. The time delays are mostly 1-2 day and represent the hemispherical asymmetry. The globally-estimated spatial patterns of the correlation between solar flux and in-situ satellite measurements show poor correlations in the (magnetic) equatorial region, which are not found from the ground measurements of vertically-integrated electron content. We suggest that the most plausible cause for the poor correlation is the vertical movement of ionization due to atmospheric dynamic processes that is not controlled by the solar extreme ultraviolet radiation.

    2008-07-01

    The day-to-day reliability of lower leg volume is poorly documented. This investigation determined the day-to-day reliability of lower leg volume (soleus and gastrocnemius) measured using water displacement. Thirty young adults (15 men and 15 women) had their right lower leg volume measured by water displacement on five separate occasions. The participants performed normal activities of daily living and were measured at the same time of day after being seated for 30 min. The results revealed a high day-to-day reliability for lower leg volume. The mean percentage change in lower leg volume across days compared to day 1 ranged between 0 and 0.37%. The mean within subjects coefficient of variation in lower leg volume was 0.72% and the coefficient of variation for the entire sample across days ranged from 5.66 to 6.32%. A two way mixed model intraclass correlation (30 subjects x 5 days) showed that the lower leg volume measurement was highly reliable (ICC = 0.972). Foot and total lower leg volumes showed similarly high reliability. Water displacement offers a cost effective and reliable solution for the measurement of lower leg edema across days. PMID:18351378

  6. Correlation of interannual length-of-day variation with El Nino/Southern Oscillation, 1972-1986

    Chao, B. Fong

    1988-01-01

    Correlation between interannual length-of-day (LOD) changes and an index representation of El Nino/Southern Oscillation (ENSO) for the period of 1972-1986 was examined in two ways: as the cross-correlation function in the time domain and as the complex coherence spectrum in the frequency domain. The ENSO representation was derived from barometric measurements from the Tahiti and Darwin, Australia, meteorological stations, as the difference of the sea-level pressure between the two locations. The cross correlation between this ENSO representation and LOD variation on the interannual time scale was found to have a maximum value of 0.68 and the LOD phase lag of 2 months, indicating that most of the interannual LOD variation is caused by ENSO, and that the transfer of ENSO's axial angular momentum to the solid earth lags behind the Tahiti-Darwin pressure variation by about 2 months. The corresponding coherence spectrum showed minimum correlation around biennial periods, indicating an influence of the stratospheric quasi-biennial oscillation on LOD variations.

    In this paper, a novel random facial variation modeling system for sparse representation face recognition is presented. Although recently Sparse Representation-Based Classification (SRC) has represented a breakthrough in the field of face recognition due to its good performance and robustness, there is the critical problem that SRC needs sufficiently large training samples to achieve good performance. To address these issues, we challenge the single-sample face recognition problem with intra-class differences of variation in a facial image model based on random projection and sparse representation. In this paper, we present a developed facial variation modeling systems composed only of various facial variations. We further propose a novel facial random noise dictionary learning method that is invariant to different faces. The experiment results on the AR, Yale B, Extended Yale B, MIT and FEI databases validate that our method leads to substantial improvements, particularly in single-sample face recognition problems.

    2016-01-01

    Emotions are increasingly inferred linguistically from online data with a goal of predicting off-line behavior. Yet, it is unknown whether emotions inferred linguistically from online communications correlate with actual changes in off-line activity. We analyzed all 886,000 trading decisions and 1,234,822 instant messages of 30 professional day traders over a continuous 2 year period. Linguistically inferring the traders’ emotional states from instant messages, we find that emotions expressed in online communications reflect the same distributions of emotions found in controlled experiments done on traders. Further, we find that expressed online emotions predict the profitability of actual trading behavior. Relative to their baselines, traders who expressed little emotion or traders that expressed high levels of emotion made relatively unprofitable trades. Conversely, traders expressing moderate levels of emotional activation made relatively profitable trades. PMID:26765539

    This study describes: 1. The therapeutic effects on anorexia nervosa (AN) and bulimia nervosa (BN) patients of a psycho-nutritional intensive day-hospital program; 2. The possible correlation between the changes observed in the psychometric tests and the variations of a number of biological parameters. Forty-six female patients (24 AN and 22 BN) were assessed through a semi-structured clinical interview based on DSM-IV criteria for Eating Disorders (ED) and a number of psychometric tests (SCL-90R, BDI, EDI-2, EAT-40, BITE, BAT) at the beginning and at the end of treatment, and after a 6-month follow-up. At these three times, we also assessed the plasma level of leptin, cortisol, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and 17beta-estradiol together with body mass index (BMI) and menstrual cycle. From beginning to discharge, the scores on all psychometric tests improved in the whole sample, except for the Perfectionism subscale of EDI-2 in both groups (AN and BN), the Anger-Hostility, Phobic Anxiety and Paranoid Ideation subscales of SCL-90 and the Interpersonal Distrust subscale of EDI-2 in the BN group. At follow-up, there was a worsening of the BITE scores and of a number of EDI-2 subscales, especially in the AN subgroup - with these changes correlating with the trend of BMI. In AN patients, plasma leptin levels changed from the beginning to the end of treatment and at follow-up according to BMI changes. The mean plasma leptin level in the BN subgroup was higher than in the AN one. We found a statistically significant correlation with the scores of BDI, SCL-90R Depression and Ineffectiveness subscales, EAT-40, BITE-Symptom subscale and the trend of menses dividing these patients into two subgroups (according to the plasma leptin concentration, higher or lower than the top leptin level in the anorexics). These data seem to confirm that leptin secretion doesn't correlate univocally to BMI. PMID:16755167

    Lungfish (Dipnoi) are the closest living relatives to tetrapods, and they represent the transition from water to land during vertebrate evolution. Lungfish are armed with immunoglobulins (Igs), one of the hallmarks of the adaptive immune system of jawed vertebrates, but only three Ig forms have been characterized in Dipnoi to date. We report here a new diversity of Ig molecules in two African lungfish species (Protopterus dolloi and Protopterus annectens). The African lungfish Igs consist of three IgMs, two IgWs, three IgNs, and an IgQ, where both IgN and IgQ originated evidently from the IgW lineage. Our data also suggest that the IgH genes in the lungfish are organized in a transiting form from clusters (IgH loci in cartilaginous fish) to a translocon configuration (IgH locus in tetrapods). We propose that the intraclass diversification of the two primordial gnathostome Ig classes (IgM and IgW) as well as acquisition of new isotypes (IgN and IgQ) has allowed lungfish to acquire a complex and functionally diverse Ig repertoire to fight a variety of microorganisms. Furthermore, our results support the idea that tetrapod-specific Ig classes did not evolve until the vertebrate adaptation to land was completed ?360 million years ago. PMID:24676685

    2010-06-01

    Inter-day training reliability and variability in artistic gymnastics vaulting was determined using a customised infra-red timing gate and contact mat timing system. Thirteen Australian high performance gymnasts (eight males and five females) aged 11-23 years were assessed during two consecutive days of normal training. Each gymnast completed a number of vault repetitions per daily session. Inter-day variability of vault run-up velocities (at -18 to -12 m, -12 to -6 m, -6 to -2 m, and -2 to 0 m from the nearest edge of the beat board), and board contact, pre-flight, and table contact times were determined using mixed modelling statistics to account for random (within-subject variability) and fixed effects (gender, number of subjects, number of trials). The difference in the mean (Mdiff) and Cohen's effect sizes for reliability assessment and intra-class correlation coefficients, and the coefficient of variation percentage (CV%) were calculated for variability assessment. Approach velocity (-18 to -2m, CV = 2.4-7.8%) and board contact time (CV = 3.5%) were less variable measures when accounting for day-to-day performance differences, than pre-flight time (CV = 17.7%) and table contact time (CV = 20.5%). While pre-flight and table contact times are relevant training measures, approach velocity and board contact time are more reliable when quantifying vaulting performance. PMID:20806844

    Light curves of 3C 279 are presented in optical (R-band), X-rays (RXTE/PCA), and gamma rays (CGRO/EGRET) for 1999 Jan-Feb and 2000 Jan-Mar. During both of those epochs the gamma-ray levels were high, and all three observed bands demonstrated substantial variation, on time scales as short as one day. Correlation analyses provided no consistent pattern, although a rather significant optical/gamma-ray correlation was seen in 1999, with a gamma-ray lag of approximately 2.5 days, and there are other suggestions of correlations in the light curves. For comparison, correlation analysis is also presented for the gamma-ray and X-ray light curves during the large gamma-ray flare in 1996 Feb and the two gamma-bright weeks leading up to it; the correlation at that time was strong, with a gamma-ray/X-ray offset of no more than one day.

    Background Previous studies of the reproducibility of blood pressure (BP) dipping have yielded inconsistent results. Few have examined factors that may influence dayto-day differences in dipping. Methods and Results Ambulatory BP monitoring was performed on three occasions, approximately one week apart, in 115 untreated adult subjects with elevated clinic BPs. The mean±SD BP dip was 18±7/15±5 mmHg (sleep/awake BP ratio = 0.87±0.05/0.82±0.06), with a median (interquartile range) day-to-day variation of 5.2 (3.1–8.1)/4.3(2.8–5.6) mmHg. There was no decrease in variability with successive measurements. The reproducibility coefficient (5.6 [95% CI 5.1, 6.1] mmHg) was greater and the intraclass correlation coefficient (0.53 [95% CI 0.42, 0.63]) was smaller for the systolic dip than for 24-hour or awake systolic BPs, suggesting greater day-today variability in dipping. Variability in systolic dipping was greater in subjects with higher awake BP, but was not related to age, gender, race, or body mass index. Within individuals, day-to-day variations in dipping were related to variations in the fragmentation index (p < 0.001), a measure of sleep quality. Conclusions Although mean 24-hour and awake BPs were relatively stable over repeated monitoring days, our study confirms substantial variability in BP dipping. Day-to-day differences in dipping are related to sleep quality. PMID:23850195

    Various lines of evidence suggest that appetite-related neuropeptides in the hypothalamus are regulated by adiposity signals such as leptin and insulin in mammals. In the present study, we examined age-dependent changes in the weight of abdominal fat and hypothalamic mRNA levels of neuropeptide Y (NPY, an orexigenic neuropeptide) and proopiomelanocortin (POMC, a precursor of anorexigenic neuropeptides) in growing chickens at 7, 14, 21 and 28 days of age. Hypothalamic NPY mRNA levels were significantly (P < 0.05) decreased after 14 days of age, whereas hypothalamic POMC mRNA levels were significantly (P < 0.05) increased at 28 days of age. The percentage of abdominal fat was significantly increased after 14 days of age in chickens. We next examined the correlation of hypothalamic NPY and POMC mRNA levels and several parameters at 28 days of age. There were no significant correlations between hypothalamic mRNA levels of NPY or POMC and the percentage of abdominal fat. These findings suggest that the gene expressions of NPY and POMC do not depend on adiposity in chickens, at least in 28-day-old layer chickens. PMID:25441031

    We present results of year-long analysis of VLF signals, both for VTX-Malda (`west-east' propagation path) and VTX-Pune (`east-west' propagation path). We analyzed whole year data of 2008 and 2009 for VTX-Malda and VTX-Pune propagation path, respectively. In both the cases we found that `VLF day-length' (defined as time difference between sunset terminator time and sunrise terminator time) became anomalously high 1-2 days before an earthquake. Besides this year-long study we have also done some case by case analysis. On 9th January, 2009 an earthquake of magnitude 5.5 occurred at Carlsberg Ridge (latitude 10.3(°) N, longitude 57.1(°) E). In a separate incident, on 3rd November, 2009, another earthquake of magnitude 5.4 occurred at Andaman Islands (latitude 14.1(°) N, longitude 93.1(°) E). We analyze VLF signals for VTX-Pune (`east-west’ propagation path) propagation path around these two earthquake days and found that for both of these cases, the `VLF-day-length' became anomalously high two days before the event. This agrees well with statistical analysis based on year-long data for VTX-Pune path. Furthermore, during time period of June, 2010, two major earthquakes of low-depth ( 10Km) and high magnitude (M>5) occurred near NWC-Salt Lake (east-west propagation path) propagation paths. First one occurred on 13th June, 2010 at Nicobar Islands, India (latitude 7.8(°) N, longitude 92.0(°) E). Its magnitude was 5.1 (in Richter scale). The second one of magnitude 6.0 (in Richter Scale) occurred on 19th June, 2010 at Andaman Islands, India (latitude 13.4(°) N, longitude 93.0(°) E). For both of these two earthquakes, we found that VLF-day-length, became anomalously high one day before earthquakes. We claim that these were pre-cursors of the earthquakes which occurred in Andaman and Nicober Islands.

    1997-01-01

    A Lomb (spectral) analysis was performed on the galactic comsic ray flux from February 1996 to June 1996. The most probable frequency is approximately 28 days and not 26 or 27 days, corresponding to one solar rotation. The amplitude of the recurrent cosmic ray decreases (RCRDs) is approximately 2.3 percent on both spacecraft. The variation in the solar wind speed shows the same periodicites and is anticorrelated to the variation in the cosmic ray flux. In contrast to the RCRDs, the amplitude found in the solar wind speed is four times larger at WIND (120 km/s) than at Ulysses (32 km/s). The solar wind proton density and magnetic field strength yielded no significant periodicities, neither at Ulysses nor at WIND. Comparing the RCRDs with coronal hole structures observed in the FE XIV line, it was found that a single coronal hole close to the heliographic equator can account for the RCRDs observed 'simultaneously' at Ulysses and SOHO. The coronal hole boundaries changed towards lower Carrington longitudes and vanished slowly. The changes of the boundaries during the investigated period could explain a 28-day periodicity.

    Summary Background: stabilometry is commonly used from clinicians and posturologists for stability and postural assessment of patients. In the daily practice a large number of posturologists are usual to control the effect of their treatments on the same subject through stabilometry but tests are not always performed at the same time, so it is necessary to be sure that data are not influenced by the time-of-day. The aim of this study was to evaluate the time-of-day effect on stabilometric parameters and theirs variation. Methods: for this aim 61 healty sportsmen performed on four repetitions of the stabilometric test during the same day (morning - evening). Data collected from each test were: centre of pressure sway path length, Naiperian logarithm of the ellipse of confidence area, of the x mean and of the y mean, eccentricity of the ellipse area. Results: no significant difference was found in any parameter at any time of the day. Intra-class Correlation Coefficient value confirmed the reliability of the stabilometric evaluation in healty subjects (sway path length 0.836 and 0.816 for open and closed eyes, respectively). Conclusion: these findings suggest that stabilometry evaluation is not affected by a time-of-day, therefore the test and retest in different time of day is reliable to assess postural sway.

    In December 1995 the Ulysses spacecraft was at a radial distance of 3 AU from the Sun and 60{degree} northern heliographic latitude. To that time the Solar and Heliospheric Observatory (SOHO) started its mission. On board of both spacecraft particle sensors are measuring electrons, protons and helium nuclei in the MeV to GeV energy range. In early 1996 the counting rates of several hundred MeV galactic cosmic rays at Ulysses and at SOHO (Earth orbit) were modulated by recurrent cosmic ray decreases (RCRDs). The RCRDs at SOHO were found to be associated with a corotating interaction region (CIRs). A Lomb (spectral) analysis was performed on the galactic cosmic ray flux from February 1996 to June 1996. Surprisingly, the most probable frequency is {approximately} 28 days and not 26 or 27 days, corresponding to one solar rotation. The amplitude of the RCRDs is {approximately} 2.3% on both spacecraft. The variation in the solar wind speed shows the same periodicities and is anticorrelated to the variation in the cosmic ray flux. In contrast to the RCRDs the amplitude found in the solar wind speed is four times larger at WIND (120 km/s) than at Ulysses (32 km/s). The solar wind proton density and magnetic field strength yielded no significant periodicities, neither at Ulysses nor at WIND. Comparing the RCRDs with coronal hole structures observed in the FE XIV line, they found that a single coronal hole close to the heliographic equation can account for the RCRDs observed simultaneously at Ulysses and SOHO. The coronal hole boundaries changed towards lower Carrington longitudes and vanished slowly. The changes of the boundaries during the investigated period could explain a 28 day periodicity.

    Electronic noses (e-noses), artificial sensor systems generally consisting of chemical sensor arrays for the detection of volatile compound profiles, have potential applications in respiratory medicine. We assessed within-day and between-day repeatability of an e-nose made from 32 sensors in patients with stable chronic obstructive pulmonary disease (COPD). We also compared between-day repeatability of an e-nose, fraction of exhaled nitric oxide (FENO) and pulmonary function testing. Within-day and between-day repeatability for the e-nose was assessed in two breath samples collected 30 min and seven days apart, respectively. Repeatability was expressed as an intraclass correlation coefficient (ICC). All sensors had ICC above 0.5, a value that is considered acceptable for repeatability. Regarding within-day repeatability, ICC ranged from 0.75 to 0.84 (mean = 0.80 ± 0.004). Sensors 6 and 19 were the most reproducible sensors (both, ICC = 0.84). Regarding between-day repeatability, ICC ranged from 0.57 to 0.76 (mean = 0.68 ± 0.01). Sensor 19 was the most reproducible sensor (ICC = 0.76). Within-day e-nose repeatability was greater than between-day repeatability (P < 0.0001). Between-day repeatability of FENO (ICC = 0.91) and spirometry (ICC range = 0.94-0.98) was greater than that of e-nose (mean ICC = 0.68). In patients with stable COPD, the e-nose used in this study has acceptable within-day and between-day repeatability which varies between different sensors. PMID:23445725

    In the present work we compared the appearance of carbohydrate binding sites for mannose, maltose, sialic acid and N-acetyl-glucosamine in the 11 to 13-day-old mouse embryo with the appearance of BSA and lectin binding sites. The carbohydrate-binding sites were localized with FITC-coupled neoglycoproteins, synthesized by chemical glycosylation of bovine serum albumin (BSA). These localizations were compared with binding of the FITC-labelled unglycosylated BSA. Furthermore the localizations of neoglycoprotein and BSA binding sites were correlated with binding of the FITC-labelled lectins WGA, RCA I and Con A. Initial appearance of neoglycoprotein binding sites occurred in the lens capsule of the 13 day old mouse embryo. Binding sites for the unglycosylated BSA appeared earlier, i.e. already in the 12-day-old embryo, in the basement membranes of the choroid plexus and the lung bud and lectin binding sites were seen in these structures in the 11-day-old embryo. The staining of the basement membrane and the lens capsule for BSA binding sites in the 12-and 13-day-old embryos correspond to WGA binding to these membranes. From these results we concluded that 1) specific carbohydrates which are probably involved in embryonic development appear much earlier in the embryo than the endogenous lectins which are able to react with these carbohydrates and 2) BSA is a protein which like WGA probably binds N-acetylglucosamine or sialic acid moieties.

    Night-time light imagery offers a unique view of the Earth's surface. In the past, the nighttime light data collected by the DMSP-OLS sensors have been used as efficient means to correlate with the global socio-economic activities. With the launch of Suomi National Polar-orbiting Partnership (S-NPP) satellite in October 2011, the Day Night Band (DNB) of the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard S-NPP represents a major advancement in night time imaging capabilities because it surpassed its predecessor DMSP-OLS in radiometric accuracy, spatial resolution, and geometric quality. In this paper, we compared the performance of DNB image and DMSP image in correlating regional socio-economic activities and analyzed the leading causes for the differences. The correlation coefficients between the socio-economic variables such as population, regional GDP etc. and the characteristic variables derived from the night time light images of DNB and DMSP at provincial level in China were computed as performance metrics for comparison. In general, the correlation between DNB data and socio-economic data is better than that of DMSP data. To explain the difference in the correlation, we further analyzed the effects of several factors such as radiometric saturation and quantization of DMSP data, low spatial resolution, different data acquisition times between DNB and DMSP images, and difference in the transformation used in converting digital number (DN) value to radiance.

    With salivary assessment of steroid hormones increasing, more work is needed to address fundamental properties of steroid hormone levels in humans. Using a test-retest design and radioimmunoassay assessment of salivary steroids, we tested the reliability of testosterone, cortisol, and progesterone levels across two weeks, as well as the effects of oral contraceptives, menstrual cycle phase, and time of day on steroid hormone levels. Testosterone and cortisol were found to be highly reliable in both sexes. Progesterone was found to be reliable after collapsing across sex. Oral contraceptive use was associated with lower levels of testosterone, but did not affect cortisol. Contrary to expectations, oral contraceptives also did not affect progesterone. Menstrual cycle was found to affect levels of progesterone, but not testosterone or cortisol. Time of day had an effect on cortisol, on progesterone only at one testing time, and no effect on testosterone. We explored the interhormone correlations among testosterone, progesterone, and cortisol. All three hormones were positively correlated with one another in men. In women, progesterone was positively correlated with testosterone and cortisol, but testosterone and cortisol were uncorrelated. PMID:19833145

    Introduction Objective methods like accelerometers are feasible for large studies and may quantify variability in day-to-day physical activity better than self-report. The variability between days suggests that day of the week cannot be ignored in the design and analysis of physical activity studies. The purpose of this paper is to investigate the optimal number of days needed to obtain reliable estimates of weekly habitual physical activity using the wrist-worn GENEActiv accelerometer. Methods Data are from a subsample of the Mitchelstown cohort; 475 (44.6% males; mean aged 59.6±5.5 years) middle-aged Irish adults. Participants wore the wrist GENEActiv accelerometer for 7-consecutive days. Data were collected at 100Hz and summarised into a signal magnitude vector using 60s epochs. Each time interval was categorised according to intensity based on validated cut-offs. Spearman pairwise correlations determined the association between days of the week. Repeated measures ANOVA examined differences in average minutes across days. Intraclass correlations examined the proportion of variability between days, and Spearman-Brown formula estimated intra-class reliability coefficient associated with combinations of 1–7 days. Results Three hundred and ninety-seven adults (59.7±5.5yrs) had valid accelerometer data. Overall, men were most sedentary on weekends while women spent more time in sedentary behaviour on Sunday through Tuesday. Post hoc analysis found sedentary behaviour and light activity levels on Sunday to differ to all other days in the week. Analysis revealed greater than 1 day monitoring is necessary to achieve acceptable reliability. Monitoring frame duration for reliable estimates varied across intensity categories, (sedentary (3 days), light (2 days), moderate (2 days) and vigorous activity (6 days) and MVPA (2 days)). Conclusion These findings provide knowledge into the behavioural variability in weekly activity patterns of middle-aged adults. Since Sunday differed from all other days in the week this suggests that day of the week cannot be overlooked in the design and analysis of physical activity studies and thus should be included in the study monitoring frames. Collectively our data suggest that six days monitoring, inclusive of Saturday and Sunday, are needed to reliably capture weekly habitual activity in all activity intensities using the wrist-worn GENEActiv accelerometer.

    The reliability of accelerometry for measuring sedentary behavior in preschoolers has not been determined, thus we determined how many days of accelerometry monitoring are necessary to reliably estimate daily time spent in sedentary behavior in preschoolers. In total, 191 and 150 preschoolers (three to five years) wore ActiGraph accelerometers (15-s epoch) during the in-school (≥4 days) and the total-day (≥6 days) period respectively. Accelerometry data were summarized as time spent in sedentary behavior (min/h) using three different cutpoints developed for preschool-age children (<37.5, <200, and <373 counts/15 s). The intraclass correlations (ICCs) and Spearman-Brown prophecy formula were used to estimate the reliability of accelerometer for measuring sedentary behavior. Across different cutpoints, the ICCs ranged from 0.81 to 0.92 for in-school sedentary behavior, and from 0.75 to 0.81 for total-day sedentary behavior, respectively. To achieve an ICC of ≥0.8, two to four days or six to nine days of monitoring were needed for in-school sedentary behavior and total-day sedentary behavior, respectively. These findings provide important guidance for future research on sedentary behavior in preschool children using accelerometry. Understanding the reliability of accelerometry will facilitate the conduct of research designed to inform policies and practices aimed at reducing sedentary behavior in preschool children.

  15. Learning Low-Rank Class-Specific Dictionary and Sparse Intra-Class Variant Dictionary for Face Recognition

    2015-01-01

    Face recognition is challenging especially when the images from different persons are similar to each other due to variations in illumination, expression, and occlusion. If we have sufficient training images of each person which can span the facial variations of that person under testing conditions, sparse representation based classification (SRC) achieves very promising results. However, in many applications, face recognition often encounters the small sample size problem arising from the small number of available training images for each person. In this paper, we present a novel face recognition framework by utilizing low-rank and sparse error matrix decomposition, and sparse coding techniques (LRSE+SC). Firstly, the low-rank matrix recovery technique is applied to decompose the face images per class into a low-rank matrix and a sparse error matrix. The low-rank matrix of each individual is a class-specific dictionary and it captures the discriminative feature of this individual. The sparse error matrix represents the intra-class variations, such as illumination, expression changes. Secondly, we combine the low-rank part (representative basis) of each person into a supervised dictionary and integrate all the sparse error matrix of each individual into a within-individual variant dictionary which can be applied to represent the possible variations between the testing and training images. Then these two dictionaries are used to code the query image. The within-individual variant dictionary can be shared by all the subjects and only contribute to explain the lighting conditions, expressions, and occlusions of the query image rather than discrimination. At last, a reconstruction-based scheme is adopted for face recognition. Since the within-individual dictionary is introduced, LRSE+SC can handle the problem of the corrupted training data and the situation that not all subjects have enough samples for training. Experimental results show that our method achieves the state-of-the-art results on AR, FERET, FRGC and LFW databases. PMID:26571112

    Aspartate transaminase, a liver specific enzyme released into serum following acute liver injury, is used in experimental organ preservation studies as a measure of liver IR injury. Whether post-operative serum transaminases are a good indicator of IR injury and subsequent graft and patient survival in human liver transplantation remains controversial. A single centre prospectively collected liver transplant database was analysed for the period 1988-2012. All patients were followed up for 5 years or until graft failure. Transaminase levels on the 1st, 3rd and 7th post-operative days were correlated with the patient demographics, operative outcomes, post-operative complications and both graft and patient survival via a binary logistic regression analysis. Graft and patient survival at 3 months was 80.3% and 87.5%. AST levels on the 3rd (P = 0.005) and 7th (P = 0.001) post-operative days correlated with early graft loss. Patients were grouped by their AST level (day 3): <107iU, 107-1213iU, 1213-2744iU and >2744iU. The incidence of graft loss at 3 months was 10%, 12%. 27% and 59% and 1-year patient mortality was 12%, 14%, 27% and 62%. Day 3 AST levels correlate with patient and graft outcome postliver transplantation and would be a suitable surrogate endpoint for clinical trials in liver transplantation. PMID:26615011

    The between-days variability in ascertained gain factors for calibration of a wearable respiratory inductance plethysmograph (RIP) and validity thereof for the repeated use during exercise were examined. Consecutive 5-min periods of standing still, slow running at 8?kmh(-1), fast running at 14?kmh(-1) (male) or 12?kmh(-1) (female) and recovery were repeated by 10 healthy subjects on 5 days. Breath-by-breath data were recorded simultaneously by flow meter and RIP. Gain factors were determined individually for each trial (CALIND) via least square regression. Reliability and variability in gain factors were quantified respectively by intraclass correlation coefficients (ICC) and limits of agreement. Within a predefined error range of 20% the amount of RIP-derived tidal volumes after CALIND was compared to corresponding amounts when gain factors of the first trial were applied on the following 4 trials (CALFIRST). ICC ranged within 0.96 and 0.98. The variability in gain factors (up to ?24.06%) was reduced compensatively by their sum. Amounts of breaths within the predefined error range did not differ between CALIND and (CALFIRST) (P>0.32). The between-days variability of gain factors for a wearable RIP-device does not show impaired reliability in further derived tidal volumes. PMID:25254900

    Reproducibility and validity testing of appetite ratings and energy intakes are needed in experimental and natural settings. Eighteen healthy young women ate a standardized breakfast for 8 days. Days 1 and 8, they rated their appetite (Hunger, Fullness, Desire to Eat, Prospective Food Consumption (PFC)) over a 3.5 h period using visual analogue scales, consumed an ad libitum lunch, left the research center and recorded food intake for the remainder of the day. Days 2-7, participants rated their at-home Hunger at 0 and 30 min post-breakfast and recorded food intake for the day. Total area under the curve (AUC) over the 180 min period before lunch, and energy intakes were calculated. Reproducibility of satiety measures between days was evaluated using coefficients of repeatability (CR), coefficients of variation (CV) and intra-class coefficients (ri). Correlation analysis was used to examine validity between satiety measures. AUCs for Hunger, Desire to Eat and PFC (ri = 0.73-0.78), ad libitum energy intakes (ri = 0.81) and total day energy intakes (ri​ = 0.48) were reproducible; fasted ratings were not. Average AUCs for Hunger, Desire to Eat and PFC, Desire to Eat at nadir and PFC at fasting, nadir and 180 min were correlated to total day energy intakes (r = 0.50-0.77, P < 0.05), but no ratings were correlated to lunch consumption. At-home Hunger ratings were weakly reproducible but not correlated to reported total energy intakes. Satiety ratings did not concur with next meal intake but PFC ratings may be useful predictors of intake. Overall, this study adds to the limited satiety research on women and challenges the accepted measures of satiety in an experimental setting. PMID:26763471

    We used the five weeks leading up to the 2008 presidential election as a backdrop to examine the ways that the brain processes attitudes and beliefs under different circumstances. We examined individual differences in personal issue importance and trait perspective-taking, as well as the temporal context in which attitude representation took place (i.e. number of days until the election). Finally, we examined the extent to which similar or dissimilar processes were recruited when considering the attitudes of political ingroup and outgroup candidates. Brain regions involved in social cognition and theory of mind, and to a lesser extent the limbic system, were modulated by these factors. Higher issue importance led to greater recruitment of neural regions involved in social cognition, across target perspectives. Higher trait perspective-taking was also associated with greater recruitment of several regions involved in social cognition, but differed depending on target perspective; greater activity was observed in prefrontal regions associated with social cognition when considering the perspective of one's own candidate compared with the opponent, and this effect was amplified closer to the election. Taken together, these results highlight ways in which ability and motivational relevance modulate socio-affective processing of the attitudes of others. PMID:22271788

    Objective To develop a self-report questionnaire assessing the impact of vaginal dryness, soreness, itching, irritation, and pain on functioning and well-being in postmenopausal women. Methods Structured self-report items were developed to address the impact of vaginal symptoms on functioning and wellbeing based on findings from focus groups with racially/ethnically diverse, symptomatic postmenopausal women. Items were refined after cognitive interview pre-testing and then field-tested among symptomatic postmenopausal women enrolled in a multiethnic cohort study in California. Exploratory (SAS PROC VARCLUS) and confirmatory factor analyses evaluated factor structure and eliminate poorly fitting items. Additional evidence of construct validity was obtained via examination of correlations with other measures of related constructs. Internal consistency and test-re-test reliability were assessed using Cronbach’s alpha and correlation coefficients, respectively. Results Of the 745 postmenopausal women completing the draft questionnaire, mean (SD) age was 56.2 (8.5) years, and 66% were racial/ethnic minorities. The refined questionnaire included four multi-item scales addressing symptom impact on: 1) activities of daily living, 2) emotional well-being, 3) sexual functioning, and 4) self-concept and body image. The four factor model provided good approximate fit (comparative fit index = 0.987, standardized root-mean-square residual = 0.038). Correlations with other measures of symptom bothersomeness, sexual function, depression, and anxiety conformed to hypotheses. Cronbach’s alpha ranged from 0.82 to 0.93. Intra-class coefficients ranged from 0.47 to 0.72. Conclusions The Day-to-Day Impact of Vaginal Aging (DIVA) questionnaire is a new multidimensional self-report measure designed to facilitate evaluation of the impact of vaginal symptoms in postmenopausal women of diverse backgrounds.

    We determined measurement properties of the Sedentary Time and Activity Reporting Questionnaire (STAR-Q), which was designed to estimate past-month activity energy expenditure (AEE). STAR-Q validity and reliability were assessed in 102 adults in Alberta, Canada (2009–2011), who completed 14-day doubly labeled water (DLW) protocols, 7-day activity diaries on day 15, and the STAR-Q on day 14 and again at 3 and 6 months. Three-month reliability was substantial for total energy expenditure (TEE) and AEE (intraclass correlation coefficients of 0.84 and 0.73, respectively), while 6-month reliability was moderate. STAR-Q-derived TEE and AEE were moderately correlated with DLW estimates (Spearman's ρs of 0.53 and 0.40, respectively; P < 0.001), and on average, the STAR-Q overestimated TEE and AEE (median differences were 367 kcal/day and 293 kcal/day, respectively). Body mass index-, age-, sex-, and season-adjusted concordance correlation coefficients (CCCs) were 0.24 (95% confidence interval (CI): 0.07, 0.36) and 0.21 (95% CI: 0.11, 0.32) for STAR-Q-derived versus DLW-derived TEE and AEE, respectively. Agreement between the diaries and STAR-Q (metabolic equivalent-hours/day) was strongest for occupational sedentary time (adjusted CCC = 0.76, 95% CI: 0.64, 0.85) and overall strenuous activity (adjusted CCC = 0.64, 95% CI: 0.49, 0.76). The STAR-Q demonstrated substantial validity for estimating occupational sedentary time and strenuous activity and fair validity for ranking individuals by AEE. PMID:25038920

    [Purpose] The purpose of present study was to establish the same-session and between-day intra-rater reliability of measurements of extensor strength in the maximum abducted position (MABP) using hand-held dynamometer (HHD). [Subjects] Thirteen healthy volunteers (10 male, 3 female; mean ± SD: age 19.8 ± 0.8 y) participated in the study. [Methods] Participants in the prone position with maximum abduction of shoulder were instructed to hold the contraction against the ground reaction force, and peak isometric force was recorded using the HHD on the floor. Participants performed maximum isometric contractions lasting 3 s, with 3 trials in one session. Between-day measurements were performed in 2 sessions separated by a 1-week interval. Intra-rater reliability was determined using intraclass correlation coefficients (ICC). Systematic errors were assessed using Bland-Altman analysis for between-day data. [Results] ICC values for same-session data and between-day data were found to be “almost perfect”. Systematic errors not existed and only random error existed. [Conclusion] The measurement method used in this study can easily control for experimental conditions and allow precise measurement because the lack of stabilization and the impact of tester strength are removed. Thus, extensor strength in MABP measurement is beneficial for muscle strength assessment.

    The revised Xbox One Kinect, also known as the Microsoft Kinect V2 for Windows, includes enhanced hardware which may improve its utility as a gait assessment tool. This study examined the concurrent validity and inter-day reliability of spatiotemporal and kinematic gait parameters estimated using the Kinect V2 automated body tracking system and a criterion reference three-dimensional motion analysis (3DMA) marker-based camera system. Thirty healthy adults performed two testing sessions consisting of comfortable and fast paced walking trials. Spatiotemporal outcome measures related to gait speed, speed variability, step length, width and time, foot swing velocity and medial-lateral and vertical pelvis displacement were examined. Kinematic outcome measures including ankle flexion, knee flexion and adduction and hip flexion were examined. To assess the agreement between Kinect and 3DMA systems, Bland-Altman plots, relative agreement (Pearson's correlation) and overall agreement (concordance correlation coefficients) were determined. Reliability was assessed using intraclass correlation coefficients, Cronbach's alpha and standard error of measurement. The spatiotemporal measurements had consistently excellent (r≥0.75) concurrent validity, with the exception of modest validity for medial-lateral pelvis sway (r=0.45-0.46) and fast paced gait speed variability (r=0.73). In contrast kinematic validity was consistently poor to modest, with all associations between the systems weak (r<0.50). In those measures with acceptable validity, the inter-day reliability was similar between systems. In conclusion, while the Kinect V2 body tracking may not accurately obtain lower body kinematic data, it shows great potential as a tool for measuring spatiotemporal aspects of gait. PMID:26065332

    Robust pattern recognition is critical for myoelectric prosthesis (MP) developed in the laboratory to be used in real life. This study focuses on the robustness of MP control during the usage across many days. Due to the variability inhered in extended electromyography (EMG) signals, the distribution of EMG features extracted from several days' data may have large intra-class scatter. However, as the subjects perform the same motion type in different days, we hypothesize there exist some invariant characteristics in the EMG features. Therefore, give a set of training data from several days, it is possible to find an invariant component in them. To this end, an invariant feature extraction (IFE) framework based on kernel fisher discriminant analysis is proposed. A desired transformation, which minimizes the intra-class (within a motion type) scatter meanwhile maximizes the inter-class (between different motion types) scatter, is found. Five intact-limbed subjects and three transradial-amputee subjects participated in an experiment lasting ten days. The results show that the generalization ability of the classifier trained on previous days to the unseen testing days can be improved by IFE. IFE significantly outperforms Baseline (original input feature) in classification accuracy, both for intact-limbed subjects and amputee subjects (average 88.97% vs. 91.20% and 85.09% vs. 88.22%, p <; 0.05).

    The Participation Scale was developed as an observational measure of activity engagement (as rated by group facilitators) of adult day care clients with mild to moderate dementia. In a consecutive sample of 448 subjects Mokken scaling procedure was conducted to assess the latent structure of 27 questionnaire items. The study included an exploratory and a confirmatory approach. For that purpose the sample was randomly divided into two halves. Exploratory analysis revealed three dimensions of participation that adequately captured the item structure: motivation (10 items; Loevinger's H = 0.48), competence (7 items; H = 0.56) and self-confidence (4 items; H = 0.57). The structure was validated in a confirmatory analysis. In a stepwise multiple regression model 49% of the variance in motivation was explained by independent behavioural measures of apathy and affect. Apathy and cognitive impairment were significant predictors of competence in participation (R(2) = 31.2%). Negative affect was the main predictor of reduced self-confidence (R(2) = 37.9%). Cross-validation of these exploratory regression models on the confirmatory sample explained 39.6%, 29.2% and 23.1% of the variance in motivation, competence and self-confidence, respectively. Test-retest intraclass correlation coefficients (ICC2(A,1)) as determined in a random subsample of 56 participants, were 0.77 (motivation), 0.85 (competence) and 0.76 (self-confidence). The three measures allow the differentiation and ordering of individual participants on separate dimensions of activity engagement in psychogeriatric day care. PMID:25007866

  19. Validation of a previous day recall for measuring the location and purpose of active and sedentary behaviors compared to direct observation

    2014-01-01

    Purpose Gathering contextual information (i.e., location and purpose) about active and sedentary behaviors is an advantage of self-report tools such as previous day recalls (PDR). However, the validity of PDR’s for measuring context has not been empirically tested. The purpose of this paper was to compare PDR estimates of location and purpose to direct observation (DO). Methods Fifteen adult (18–75 y) and 15 adolescent (12–17 y) participants were directly observed during at least one segment of the day (i.e., morning, afternoon or evening). Participants completed their normal daily routine while trained observers recorded the location (i.e., home, community, work/school), purpose (e.g., leisure, transportation) and whether the behavior was sedentary or active. The day following the observation, participants completed an unannounced PDR. Estimates of time in each context were compared between PDR and DO. Intra-class correlations (ICC), percent agreement and Kappa statistics were calculated. Results For adults, percent agreement was 85% or greater for each location and ICC values ranged from 0.71 to 0.96. The PDR-reported purpose of adults’ behaviors were highly correlated with DO for household activities and work (ICCs of 0.84 and 0.88, respectively). Transportation was not significantly correlated with DO (ICC = -0.08). For adolescents, reported classification of activity location was 80.8% or greater. The ICCs for purpose of adolescents’ behaviors ranged from 0.46 to 0.78. Participants were most accurate in classifying the location and purpose of the behaviors in which they spent the most time. Conclusions This study suggests that adults and adolescents can accurately report where and why they spend time in behaviors using a PDR. This information on behavioral context is essential for translating the evidence for specific behavior-disease associations to health interventions and public policy. PMID:24490619

    The physical health of people with bipolar disorder is poorer in comparison to the general population, with an increased prevalence of cardiovascular and metabolic diseases. Due to the established beneficial effects, there is growing interest in the promotion of physical activity and in particular the accurate measurement of physical fitness in this population. Currently, no existing measures of physical fitness used in the general population have been tested for validity and reliability among people with bipolar disorder. Therefore, we examined the reproducibility, feasibility and correlates of the Eurofit test battery in people with bipolar disorder. From 24 men (43.0±13.0 years) and 22 women (43.9±10.2 years) with bipolar disorder two trials of the Eurofit test, administered within three days, were analyzed. All Eurofit items showed good reproducibility with intraclass correlation coefficients ranging from 0.71 for the whole body balance test to 0.98 for the handgrip force test. Significant correlations with Eurofit test items were found with age, illness duration, body mass index, smoking behavior, mean daily lithium dosage, and depressive and lifetime hypomanic symptoms. The current study demonstrates that the Eurofit test can be recommended for evaluating the physical fitness of inpatients with bipolar disorder. PMID:26165959

  5. MIDAS and HIT-6 French translation: reliability and correlation between tests.

    PubMed

    Magnoux, E; Freeman, M A; Zlotnik, G

    2008-01-01

    The aim was to evaluate the test-retest reliability of the French translation of the Migraine Disability Assessment (MIDAS) and Headache Impact Test (HIT)-6 questionnaires as applied to episodic and chronic headaches and to assess the correlation between these two questionnaires. The MIDAS and HIT-6 questionnaires, which assess the degree of migraine-related functional disability, are widely used in headache treatment clinics. The French translation has not been checked for test-retest reliability. MIDAS involves recall, over the previous 3 months, of the number of days with functional disability with regard to work and to home and social life. HIT-6 involves a more subjective and general assessment of headache-related disability over the previous 4 weeks. We expect that there may be greater impact recall bias for chronic headaches than for episodic headaches and considered it important to be able to determine if the reliability of these questionnaires is equally good for these two patient populations. Given that both questionnaires have the same objective, that of assessing headache impact, it was thought useful to determine if their results might show a correlation and if they could thus be used interchangeably. The study was approved by an external ethics committee. The subjects were patients who regularly visit the Clinique de la Migraine de Montréal, which specializes in the treatment of headaches. The MIDAS and HIT-6 questionnaires were completed by the patients during their regular visit. Twelve days later, the same questionnaires were mailed with a prepaid return envelope. Sixty-five patients were required in both the episodic and chronic headache groups, assuming an 80% questionnaire return rate. One hundred and eighty-five patients were enrolled, and 143 completed the study, 75 with episodic headaches and 68 with chronic headaches. The questionnaire return rate was 78.9%. On average, questionnaires were completed a second time 21 days after the first, with a median of 19 days. The Shrout-Fleiss intraclass correlation coefficients for MIDAS and HIT-6 were, respectively, 0.76 and 0.77 for episodic headaches and 0.83 and 0.80 for chronic headaches. The Pearson correlation coefficient between the MIDAS and HIT-6 questionnaires was 0.48 for episodic headaches and 0.58 for chronic headaches at the first compilation and 0.42 and 0.59 at the second compilation. The test-retest intraclass correlation of the French versions for both MIDAS and HIT-6 questionnaires indicates moderate reliability for episodic headache and substantial reliability for chronic headache. The correlation between the MIDAS and HIT-6 questionnaires is weak for episodic headaches, but approaches a level of 'good' for chronic headaches. PMID:17970768

    The reliability of triceps surae electromyographic responses to standing perturbations in people after stroke and healthy controls is unknown. High-Density surface Electromyography (HDsEMG) is a technique that records electromyographic signals from different locations over a muscle, overcoming limitations of traditional surface EMG such as between-day differences in electrode placement. In this study, HDsEMG was used to measure responses from soleus (SOL, 18 channels) and medial and lateral gastrocnemius (MG and LG, 16 channels each) in 10 people after stroke and 10 controls. Timing and amplitude of the response were estimated for each channel of the grids. Intraclass Correlation Coefficient (ICC) and normalized Standard Error of Measurement (SEM%) were calculated for each channel individually (single-channel configuration) and on the median of each grid (all-channels configuration). Both timing (single-channel: ICC=0.75-0.96, SEM%=5.0-9.1; all-channels: ICC=0.85-0.97; SEM%=3.5-6.2%) and amplitude (single-channel: ICC=0.60-0.91, SEM%=25.1-46.6; ICC=0.73-0.95, SEM%=19.3-42.1) showed good-to-excellent reliability. HDsEMG provides reliable estimates of EMG responses to perturbations both in individuals after stroke and in healthy controls; reliability was marginally better for the all-channels compared to the single-channel configuration.

    Ferson, M J

    1993-02-01

    The number of preschool-aged children who attend day care has increased dramatically in recent years. Factors promoting spread of infections in this setting include crowding, lack of hygiene, high prevalence of early exploratory behaviors, and the likelihood of many susceptible children being in close contact. As a result, children attending day care experience a great number of episodes of respiratory and gastrointestinal illness than do other children. Moreover, the risk of a number of specific infections, including Haemophilus influenzae type b and hepatitis A, is increased by attendance in day care. Day-care staff are at increased risk of a number of infections, some of which, including cytomegalovirus and parvovirus B19, may have adverse consequences to a fetus. The presence of children in day care increases the risk of illness among staff and family members and may promote the circulation of infections in the community as a whole. PMID:8374625

    The timed up and go (TUG) test is a commonly used assessment in older people with variations including the addition of a motor or cognitive dual-task, however in high functioning older adults it is more difficult to assess change. The quantified TUG (QTUG) uses inertial sensors to detect test and gait parameters during the test. If it is to be used in the longitudinal assessment of older adults, it is important that we know which parameters are reliable and under which conditions. This study aims to examine the relative reliability of the QTUG over five consecutive days under single, motor and cognitive dual-task conditions. Twelve community dwelling older adults (10 females, mean age 74.17 (3.88)) performed the QTUG under three conditions for five consecutive days. The relative reliability of each of the gait parameters was assessed using intra-class correlation coefficient (ICC 3,1) and standard error of measurement (SEM). Five of the measures demonstrated excellent reliability (ICC>0.70) under all three conditions (time to complete test, walk time, number of gait cycles, number of steps and return from turn time). Measures of variability and turn derived parameters demonstrated weak reliability under all three conditions (ICC=0.05-0.49). For the most reliable parameters under single-task conditions, the addition of a cognitive task resulted in a reduction in reliability suggesting caution when interpreting results under these conditions. Certain sensor derived parameters during the QTUG test may provide an additional resource in the longitudinal assessment of older people and earlier identification of falls risk. PMID:26526223

    Background: Osteoarthritis of the knee is commonly diagnosed and monitored with radiography. However, the reliability of radiographic classification systems for osteoarthritis and the correlation of these classifications with the actual degree of confirmed degeneration of the articular cartilage of the tibiofemoral joint have not been adequately studied. Methods: As the Multicenter ACL (anterior cruciate ligament) Revision Study (MARS) Group, we conducted a multicenter, prospective longitudinal cohort study of patients undergoing revision surgery after anterior cruciate ligament reconstruction. We followed 632 patients who underwent radiographic evaluation of the knee (an anteroposterior weight-bearing radiograph, a posteroanterior weight-bearing radiograph made with the knee in 45° of flexion [Rosenberg radiograph], or both) and arthroscopic evaluation of the articular surfaces. Three blinded examiners independently graded radiographic findings according to six commonly used systems—the Kellgren-Lawrence, International Knee Documentation Committee, Fairbank, Brandt et al., Ahlbäck, and Jäger-Wirth classifications. Interobserver reliability was assessed with use of the intraclass correlation coefficient. The association between radiographic classification and arthroscopic findings of tibiofemoral chondral disease was assessed with use of the Spearman correlation coefficient. Results: Overall, 45° posteroanterior flexion weight-bearing radiographs had higher interobserver reliability (intraclass correlation coefficient = 0.63; 95% confidence interval, 0.61 to 0.65) compared with anteroposterior radiographs (intraclass correlation coefficient = 0.55; 95% confidence interval, 0.53 to 0.56). Similarly, the 45° posteroanterior flexion weight-bearing radiographs had higher correlation with arthroscopic findings of chondral disease (Spearman rho = 0.36; 95% confidence interval, 0.32 to 0.39) compared with anteroposterior radiographs (Spearman rho = 0.29; 95% confidence interval, 0.26 to 0.32). With respect to standards for the magnitude of the reliability coefficient and correlation coefficient (Spearman rho), the International Knee Documentation Committee classification demonstrated the best combination of good interobserver reliability and medium correlation with arthroscopic findings. Conclusions: The overall estimates with the six radiographic classification systems demonstrated moderate (anteroposterior radiographs) to good (45° posteroanterior flexion weight-bearing radiographs) interobserver reliability and medium correlation with arthroscopic findings. The International Knee Documentation Committee classification assessed with use of 45° posteroanterior flexion weight-bearing radiographs had the most favorable combination of reliability and correlation.

    HBPM guidelines state that morning and evening measurements should be recorded and, to improve stability, the first day of measurements should be discarded. Our objective was to assess the reproducibility and reliability of a 4-day HBPM protocol with and without first day measurements. We analyzed a retrospective cohort of ambulatory patients who required a HBPM for diagnostic purposes or evaluation of treatment efficacy. A 4-day protocol was implemented, with daily duplicate measurements in the morning, afternoon and evening, using an OMRON 705 CP validated equipment. HBPM reproducibility was quantified by test-re-test correlations and standard deviation of differences (SDD) between BP measurements obtained during the entire 4 days, with and without exclusion of the first day. The reliability criterion was the stabilization of the mean and standard deviation (SD). We included 353 subjects with a total of 8224 BP recordings (median of 24 recordings per patient). We found a strong test-re-test correlation between days 1 to 4, which improved when we excluded the first day (p<0.001). We also found a reduction of the mean BP when we increased the number of days and a reduction of SDD when we excluded day 1. Therefore, we conclude that the exclusion of the first day of measurements improves the reproducibility and reliability of a 4-day protocol, and such two factors are not affected by the inclusion of afternoon measurements.

    Behavioral change is at the heart of effective primary care, but when patients don’t change, how do we account for our days? In this personal essay, I relate an encounter with a patient who wants to quit smoking, lose weight, and control her diabetes. I am discouraged when she deflects my recommendations, but a colleague’s comment encourages a deeper inquiry. Knowing the patient’s story and deepening the conversation, however, do not guarantee change. The experience reminds me why patience, humility, and faith are core values of the primary care physician. PMID:25964410

    PubMed

    Akakpo, A J

    2015-08-01

    Three-day fever is a viral disease caused by an Ephemerovirus of the family Rhabdoviridae, transmitted by arthropod vectors. It is common in tropical and sub-tropical regions, where it affects mainly domestic cattle and buffaloes, especially in intensive dairy or fattening production systems. It is of economic importance because it reduces milk production and fertility and causes abortion. The disease is generally benign. It manifests in several susceptible subjects simultaneously, with a sudden episode of fever accompanied by muscle involvement with arthritis, stiffness of the limbs, and lameness, followed by rapid recovery. The presence of a serofibrinous exudate in the joints is indicative of the disease. Clinical diagnosis is often difficult in the absence of pathognomonic signs. Epidemiological factors (proliferation of arthropod vectors), associated with a short-lived fever and the presence of many immature neutrophils, point strongly to three-day fever. In the absence of any specific treatment, the symptoms are treated with antibiotics and anti-inflammatories. Medical prophylaxis currently uses live attenuated vaccines, pending the development of recombinant vaccines, which are giving promising results. PMID:26601454

    Despite demographic progress in many regions, world population is growing by more than 90 million persons each year. This massive growth is relatively new in human history. 80 years were required to add 1 billion inhabitants after 1850, but at current rates only 11 years will be required. The course of world demographic evolution will be decided by the actions or inaction of each man and woman on the planet. Questions of population are at the center of sustainable development and should be an essential feature of any vision of the future. Correctly conducted population programs provide essential services for the health and well-being of individuals and families and facilitate the task of creating structures for sustainable economic growth. In honor of World Population Day on July 11, the Salvadoran Demographic Association has presented a series of informative articles on the relationship between population and health, environment, education, food and nutrition, reproductive health, and family planning.

    1990-01-01

    The Executive Director of the UN Centre for Human Settlements (HABITAT) discusses the 1989 World HABITAT Day message--Shelter, Health, and the Family. Women and children spend most of their time in their homes and neighborhoods. The environment and the way they live in that environment determine their health status and well being. Healthy housing encompasses protection against rain, heat, cold, and disease. Yet more than 25% of the world's population have inadequate housing which is responsible for various communicable and chronic diseases, injuries, and psychological stresses. For example, overcrowding leads to respiratory infection. Inferior building materials and designs foster the harboring and breeding of disease vectors and destruction by natural disasters. Limited access to potable water and sanitation facilities and poor personal hygiene cause death, disabilities, and blemishes to millions of people as well as fosters food contamination. 10,000 people die each day from injuries or conditions directly related to inadequate shelter and related services. The urban poor tend to be at the point where industrialization meets underdevelopment because they live in marginal areas often near refuse dumps, swamps, and areas subject to landslides, earthquake, or flooding. Social and psychological problems also emerge from such an environment which further undermine the underpinnings of a secure and pleasant family life. Few activities designed to improve shelter consider the health of the occupants, however. Education about the link between housing and health among the poor at the household and community levels may empower them to alleviate the health hazards. The Executive Director requests the international community, governments, their agencies, nongovernmental organizations, builders, planners, and policymakers to consider the link between housing and health when making policy and decisions.

  7. The day of women.

    PubMed

    Jimenez David, R

    1994-09-01

    March, 1994, was celebrated as Women's Month in the Philippines, with a focus on women's health. The theme chosen was Me, Too, a response to the ideal of feminine martyrdom. The intended message was that it is acceptable for women to look after themselves first, because only this way could they look after the other people in their lives. The Woman Who is Okey is defined as the woman who looks after her health and who practices self-care. The major health problems of women include cancer of the breast and cervix; reproductive tract infections; HIV/AIDS; poor nutrition, exacerbated by pregnancy and lactation; and increased incidence of cardiovascular disease linked to an increase in women smokers. The Woman Who is Okey is a woman who: carries out breast self examination each month, submits to a pap smear examination every year, does not smoke, spaces her pregnancies by 2-3 year intervals, knows how to protect herself from HIV/AIDS and other sexually transmitted diseases, visits a health center regularly for prenatal check-ups and other health services, and meets her hygienic and fitness needs. The campaign was broadened to include rape, violence, sexual harassment, and discrimination and exploitation of women. The activities of the Department of Health (DOH) during March 8, International Women's Day, were coordinated with those planned by women's groups spearheaded by the National Commission on the Role of Filipino Women (NCRFW). The DOH set up a permanent Women's Center in government hospitals throughout the country and began to institutionalize assistance to women who are victims of violence, including rape. The national celebration held in Manila was a day-long program organized by the NCRFW, in which close to 18,000 women participated from all political organizations. President Fidel V. Ramos was the keynote speaker. PMID:12288259

    Sheng, Guojun

    2014-03-01

    The first day of chick development takes place inside the mother hen (in utero), during which the embryo progresses from fertilization to late blastula/early gastrula formation. The salient features of developmental anatomy in this period are conserved among the sauropsids (birds and reptiles). Many of these features are also shared in prototherian (monotreme) embryos, whereas metatherian (marsupial) and eutherian (placental) embryos display significant variations. Important for understanding the evolution of early development in amniotes, the knowledge of cellular and molecular mechanisms regulating in utero chick development may also offer valuable insight into early lineage specification in prototherians and conserved features in mammalian early development. This commentary provides a snapshot of what is currently known about intrauterine chick development and identifies key issues that await further clarification, including the process of cellularization, allocation of maternal determinants, zygotic gene activation, mid-blastula transition, cell layer increase and reduction, radial symmetry breaking, early lineage segregation, and role of yolk syncytium in early patterning.

Warner Prize: Origins of Structure in Planetary Systems (by Erika Nesvold)Another excellent prize lecture started off todays sessions. The Helen B. Warner Prize is awarded for achievement in observational or theoretical astrophysics by a young researcher (no more than eight years after their Ph.D.). This years Warner Prize was presented to Ruth Murray-Clay of UC Santa Barbara. For her award lecture, Murray-Clay told us all about planetary system architecture: the number, masses, and orbits of planets in a given system.Ruth Murray-Clay [photo from http://web.physics.ucsb.edu/ ~murray/biocv.html]The underlying question motivating this type of research is: How rare is the Solar System? In other words, how likely is it that a given planetary system will have rocky planets close to their star, gas giants farther out, and ice giants at the outer reaches of the system? Answering this question will help us solve the physics problem of how and where planets form, and will also help us on our search for other planets like Earth.The data on exoplanet population from transit and radial velocity observations and from direct imaging tell us that our Solar System is not common (many systems we observe have much more eccentric gas giants), but that doesnt mean its not typical. While we wait for more and better observations of exoplanet systems, theory can help us understand why the Solar System formed the way it did, and where to look for systems that formed the same way. For example, some of Murray-Clays previous work has shown that metal-rich stars tend to host more hot Jupiters and eccentric giant planets (very different from Solar System architecture). So if we want to find more systems like our own, we need to search around stars with low-to-moderate metallicity.Extrasolar Planets: Hosts, Interactions, Formation, and Interiors (by Caroline Morley)This session was a mashup of a variety of planetary topics ranging from solar flares to interiors to habitability.Leslie Rogers kicked off the session by presenting work done in collaboration with her student Ellen Price to constrain the composition of the ultra-short period (4 hours!?!) planet candidate KOI 1843.03 using models of the objects interior. Since its so close to the star, it can only exist without being torn apart if its very dense, which allows them to calculate that it must be iron-rich like Mercury!Next Kevin Thielen, an undergrad at Eckerd College, presented results from a summer project to apply a variable polytrope index to planet models. Tom Barclay then showed models that demonstrate the huge effect that having giant planets in the outer solar system has on the formation of terrestrial planets. He finds that without Jupiter and Saturn, more planets would form (8 instead of 3-4!) and giant impacts (like the moon-forming impact) would be more frequent but less energetic.Aomawa Shields shifted to discuss her 3D GCM models to determine the orbital configurations that would lead to liquid water on the surface of the planet Kepler-62f. She determines the effect of eccentricity, axis tilt (obliquity), and rotation rate on habitability. Edward Guinan brought us closer to home discussing the potential for superflares solar flares up to hundreds of times more energetic than normalin our solar system. Analyses of Kepler data suggest that these flares likely happen every 300-500 years in Sunlike stars (way more often than previously thought!), and would devastate communications systems on Earth (and hurt astronauts in space).Peter Buhler and Taisiya Kopytova finished up the session. Peter showed how he used Spitzer secondary eclipses and MESA models to determine the tidal love number and core mass of HAT-P-13b. Taisiya presented her thesis work on observations of brown dwarfs and low-mass stars. She shows that in many cases, particularly for young objects and cold objects, the models for these objects do not fit the data very well!Press Conference: Sloan Digital Sky Survey (SDSS) IV (by Susanna Kohler)The final press conference of the meeting was all about the fourth generation of the Sloan Digital Sky Survey.In the opening talk, Michael Blanton (New York University) presented some early results from SDSS-IV, which is slated to run from 2014 to 2020. The major components to SDSS-IV are extended Baryon Oscillation Spectroscopic Survey (eBOSS), a cosmological survey of quasars and galaxies; APO Galactic Evolution Experiment (APOGEE-2), a stellar survey of the Milky Way; and Mapping Nearby Galaxies at APO (MaNGA), a survey that will map the detailed internal structure of nearly 10,000 nearby galaxies.Next up was Melissa Ness (Max Planck Institute for Astronomy), speaking about APOGEEs creation of the first global age map of the Milky Way. APOGEE obtained the spectra for 70,000 red giant stars. These spectra, combined with the stars light curves, allowed the team to infer the ages of these stars distributed across the Milky Way galaxy. The resulting map is shown in the video below. From this map, Ness says its pretty clear: the Milky Way started as a small disk, and its expanded out from there, since. Our galaxy grew, and it grew up by growing out. Heres the press release. This is a big 3D map showing the age of stars in the Milky Way the latest from #aas227: https://t.co/HiPbm9eW6J pic.twitter.com/DqG6NNsPTU jonathan jb webb (@jjbw) January 8, 2016Francesco Belfiore (University of Cambridge) gave the next talk, cleverly titled Proof That Some Galaxies Are LIERs. The title is a play on the astrophysical source known as a LINER, or Low-Ionization Nuclear Emission-line Region an area within a galactic center that displays line emission from weakly ionized or neutral atoms. These have commonly been interpreted as being a wimpy active galactic nucleus (AGN). But a closer look with MaNGA, which is able to take spectroscopic data for the whole galaxy at once, has revealed that these sources are actually distributed throughout the galaxy, rather than being nuclear hence, no N: these galaxies are LIERs. Instead of AGN, the sources may be newly born white dwarfs. Heres the press release.Artists conception of the changing look quasar as it appeared in early 2015. [Dana Berry / SkyWorks Digital, Inc.; SDSS collaboration]The final speaker was Jessie Runnoe (Pennsylvania State University), who captured everyones attention with the topic of changing look quasars. We know that quasars can transition from a bright state, where active accretion onto the galaxys central supermassive black hole is visible in their emission spectrum, to a dim state, where they look like a normal galaxy. But SDSS has just observed the quasar SDSS J1011+5442 turn off within the span of just 10 years. Based on the data, the team concludes that this quasar exhausted the supply of gas in its immediate vicinity, turning off when there was no longer anything available to accrete. Runnoe showed an awesome animation of this process, which you can check out here. Heres the press release.Coffee, Black Holes, Editors and Beer: The Science-Writing Life (by Susanna Kohler)This talk was a part of the series Beyond the Academy: Showcasing Astronomy Alumni in Non-Academic Careers. Matthew Francis is a former academic scientist (with a PhD in physics and astronomy) who transitioned to being a freelance science writer. Wearing a distinctive bowler hat, Francis talked to a room full of students (and some non-students!) about what its like to be a science writer. Here are some highlights from among his recommendations and comments.A day in the life of a science writer.About the mechanics of freelancing:Some sample numbers: he wrote 73 articles in 2015, for 12 different publications. These vary in length and time invested. He supports himself fully by freelancing.The time between pitching a story and getting it published can vary between a few hours for online news stories to months for feature articles.The answer to the question, What do science writers do all day? (see photo)About transitioning into science writing:If youre interested in a science writing career, start blogging now to build up a portfolio.Use your training! As a researcher, you can read plots, understand scientific articles, and talk to scientists as colleagues. These are great strengths.About writing for the public:Theres a difference in writing for academics and the public: when writing for academics, youre trying to bring them up to your level. When writing for the public, thats probably not the goal.That said, on the subject of dumbing down: If you think your audience is somehow deficient, youve already failed.writing for the web: youll make fundamental spelling/grammar errors, youll find them only when you read the published post. Truth! #aas227 astrobites (@astrobites) January 8, 2016At the end of the session, Francis told us what he considers to be the best part of being a science writer: getting to tell people something that theyve never heard before. Getting it right is communicating a mundane fact to you that is an astounding surprise to your audience.Plenary Talk: News on the Search for Milky Way Satellite Galaxies (by Susanna Kohler)The second-to-last plenary talk of the meeting was given by Keith Bechtol, John Bahcall fellow at University of Wisconsin-Madison. Bechtol spoke about the recent discovery of new satellite galaxies of the Milky Way. Dwarf galaxies orbiting the Milky Way are often hard to spot because they are so faint while globular clusters have mass-to-light ratios of around 1, the ultra-faint satellites around the Milky Way can have mass-to-light ratios of hundreds or thousands! A combination of better facilities and improved analysis techniques has been lengthening the list of known Milky Way satellites, however: SDSS took us from ~10 to ~30 in the last ten years, and facilities like the Dark Energy Survey Camera (DES), Pan-STARRS 1, SkyMapper, and Hyper Suprime-Cam pushed that number to ~50 in 2015.Bechtol plenary on the discovery of new MW satellites #aas227 pic.twitter.com/3GH0Sd2J8c Matthias Steinmetz (@GalacticRAVE) January 8, 2016The new candidates discovered with DES are all less luminous and more distant than previous satellites found. One interesting aspect of this sample is that 15/17 of the candidates fall in the southern half of the DES footprint, and are located near the Large and Small Magellanic Clouds. This anisotropy is not thought to be a selection effect so is it coincidence, or could they possibly be satellites of satellites? Were not sure yet!Why do we care about finding Milky Way satellites? There are lots of reasons, but one of the biggest is that they may help us to unravel some of the mysteries of dark matter. These faint-but-massive galaxies were probably born in the Milky Ways dark-matter halo, and they could be great places to indirectly detect dark matter. In addition, theres the missing satellite problem the phenomenon wherein the cold-dark-matter model predicts there should be hundreds of satellites around the Milky Way, yet weve only found a few dozen. Finding more of these galaxies would help clear up whether its the theory or the observations that are wrong.One more time, it shouldnt be called the Missing Satellite Problem. The theorists have a Satellite Overabundance Problem. #aas227 Peter Yoachim (@PeterYoachim) January 8, 2016Overall, Bechtol declares, its been an exciting year for the discovery of new Milky Way satellites, and with new surveys and facilities still in development, the future looks promising as well!Hack Day (by Meredith Rawls)A large contingent of astronomers spent our Friday working on small projects or chunks of larger projects that could be accomplished in a day. Astrobites has written about hack days before. Look for a dedicated recap post with all the great projects later in January!

Along with several fellow authors from astrobites.com, I will bewritingupdates on selectedevents at themeeting and posting at the end of each day. Follow along here or atastrobites.com, or catch ourlive-tweeted updates from the@astrobites Twitter account. The usual posting schedule for AAS Nova will resumenext week.Welcome to Day 3 of the winter American Astronomical Society (AAS) meeting in Kissimmee! Several of us are attending the conference this year, and we will report highlights from each day here on astrobites. If youd like to see more timely updates during the day, we encourage you to follow @astrobites on twitter or search the #aas227 hashtag.Henry Norris Russell Lecture: Viewing the Universe with Infrared Eyes: The Spitzer Space Telescope (by Erika Nesvold)The Henry Norris Russell Award is the highest honor given by the AAS, for a lifetime of eminence in astronomy research. This years award went to Giovanni Fazio of the Harvard-Smithsonian Center for Astrophysics. Fazio became a leader in gamma ray astronomy before switching mid-career to the study of infrared astronomy, and he gave his award lecture on the latter subject, specifically on the Spitzer Space Telescope, one of the most successful infrared telescopes of all time.Artists rendering of the Spitzer space telescope. [NASA/JPL-Caltech]Spitzer has been operating for more than twelve years, and has resulted in over six thousand papers in refereed journals in that time. The telescope sits in an Earth-trailing orbit around the Sun, and is now farther from the Earth (1.4 AU) than the Earth is from the Sun. Fazio gave the audience a fascinating overview of the science done by Spitzer over more than a decade. One of the most productive areas of research for Spitzer is the study of exoplanets, which hadnt even been discovered when the Spitzer Telescope was first conceived. Spitzers high sensitivity and ability to observe exoplanets over many orbits has made it a powerhouse for learning about the temperatures, atmospheres, and orbits of exoplanets. The list of examples that Fazio provided included the first global temperature map of an exoplanet (HD 189733b), the detection of the closest transiting exoplanet (HD 219134b), and the measurement of thermal emission from a super-Earth (55 Cnc e). Spitzers large distance from the Earth (specifically, the ground-based telescopes on Earth) even allowed astronomers to observe an exoplanet via gravitational microlensing using a special technique called space-based parallax.Spitzer has also been extremely useful for observing everything from Solar System scales (such as the enormous infrared dust ring around Saturn) to galactic structures. Comparing images of galaxies observed at visible wavelengths with Spitzer images of the same galaxies at infrared wavelengths has allowed us to probe the structure and composition of galaxies at a new level.Astronomers have also used Spitzer to explore the evolution of stars. Thanks to its infrared detectors, Spitzer can look through large clouds of dust that are opaque at visible wavelengths, and observe young stellar objects in their birth environments. Cosmologists can use Spitzer to study the early universe and the formation of galaxies over twelve billion years ago. Fazio used all of these examples and more to demonstrate that Spitzer has truly changed our understanding of the universe.Climate Change for Astronomers (Meredith Rawls)Every astronomer at #aas227 wants to learn about climate change! WOW this room is ridiculously full. pic.twitter.com/ud9an0gLJG Meredith Rawls (@merrdiff) January 7, 2016The second half of the session was a presentation by Doug Duncan featuring an activity from his 101-level college course. He uses climate change as a way to teach critical thinking and scientific reasoning. Members of the audience were walked through an exercise that included interpreting plots of changing surface temperatures, think-pair-share style clicker questions, and comparing excerpts from scientific articles and the media. Eventually, students discover that the Earths overall temperature is going up, but observations can vary from year to year because heat is moving between the atmosphere and the oceans.Press Conference: Fermis Vision, First Stars, Massive Galaxy Cluster, and Dark Energy (by Susanna Kohler)Todays afternoon press conference was an exciting assortment of results, difficult to categorize under a single umbrella.First up was Marco Ajello (Clemson University), who spoke about 2FHL, the second Fermi-LAT catalog of high-energy sources. LAT stands for Large Area Telescope, an instrument on board the Fermi gamma-ray space observatory that scans the entire sky every three hours. Ajello described the contents of the 2FHL catalog: 360 gamma-ray sources, of which 75% are blazars (distant galactic nuclei with jets pointed toward us), 11% are sources within the galaxy, and the remaining 14% are unknown. With this catalog, Fermi has expanded into higher energies than ever before, providing the first map of the 50 GeV 2 TeV sky. Heres the press release.OMeara: Im a lowly spectroscopist so I dont have fun pictures to show you, just squiggly lines. #aas227 astrobites (@astrobites) January 7, 2016Next to speak, John OMeara (St. Michaels College) told us about the discovery of a gas cloud that may be a remnant from the first population of stars. OMeara showed us the emission spectrum from a distant quasar, which displays abrupt absorption by a cloud of gas located at a redshift of z~3.5. Absorption by gas clouds is not unusual but what is unusual is that this cloud is extremely metal-poor, with only 1/2500th solar metallicity. This is the lowest heavy-element content ever measured, and a sign that the cloud might have been enriched by Population III stars the theoretical first population of stars, which were born when gas in the universe was still pristine. Heres the press release.Cluster IDCS J1426.5+3508. [NASA, European Space Agency, University of Florida, University of Missouri, and University of California]Mark Brodwin (University of Missouri, Kansas City) was up next, discussing the most distant massive galaxy cluster that has ever been discovered. The cluster IDCS J1426.5+3508, weighing in at several trillion solar masses (as measured by three independent techniques!), is located at a redshift of z=1.75. Since clusters take several billion years to form, and its redshift corresponds to a time when the universe was only 3.8 billion years old, were probably seeing it at a very early age. This combination of mass and youth is unique! Brodwin also pointed out another interesting feature: the clusters core isnt centered, which means it probably underwent a major merger with another cluster within the last 500 million years. Heres the press release.The final speaker was Sukanya Chakrabarti (Rochester Institute of Technology), who gave a very interesting talk about a topic Id never heard of: galactoseismology. Galactoseismology involves observing waves in the disk of a galaxy to learn about the properties of dwarf galaxies that caused the perturbations. In this case, Chakrabarti evaluated ripples in the outer disk of our galaxy, and used these to predict the location of a dwarf galaxy that must have skimmed the outskirts of our galaxy a few hundred million years ago, causing the waves. This is a cool technique for learning about dwarf galaxies whether or not theyre visible, since theyll cause ripples even if theyre dominated by dark matter. Chakrabarti showed an awesome simulation of this dwarfs interaction with the Milky Way, which you can check out on her website. Heres the press release.

  11. International Women's Day speech.

    The objectives of the International Women's Day are: 1) to celebrate the struggle for women's rights in the economic, social, political, and cultural domain; 2) to reaffirm women's solidarity in the struggle for peace; 3) and to show what women have achieved. In 1988, Uganda's government of the National Resistance Movement created the Ministry of Women in Development. The period 1988-1990 was one of consultations, needs assessment, planning, and recruiting staff for the Ministry. From 1990 to 1993, measurable results have been achieved. The Ministry's gender concerns pertained to the sector policies of the Ministries of Agriculture, Animal Industry and Fisheries, Education, Health, Water, Energy, Minerals, and Environment Protection. Under the Umbrella Project for Women in Development, gender sensitization has been achieved with policy makers in ministries, at district level, and in the media. Gender issues have also been incorporated in the National Political School Curriculum. The Ministry has also trained a corps of 73 women trainers from 38 districts. The Ministry, with funding from DANIDA, collected women's views on the constitution through meetings and seminars in all the districts in the country. Recommendations were submitted in a consolidated report to the Constitution Commission. A pilot para-legal scheme is successfully being implemented in Kamuli district. A community-based pool of legal advisors has been developed. Legal matters that affect both women and men are undertaken at the community level. The economic emancipation of women is a crucial part of the Ministry's mandate. In conjunction with NGOs, pilot credit programs are being run in Mukono, Jinja, Mbale, and Kapchorwa districts. Cross-sectoral programs are in close collaboration with the rural water and sanitation program, the Northern Uganda rehabilitation program, and the integrated Basic Education Pilot Project to be implemented in 8 districts.

Ozel spoke to a packed room (at 8:30am!) about where the project currently stands, and where its heading in the future.The EHT has pretty much the coolest goal ever: actually image the event horizons of black holes in our universe. The problem is that the largest black hole we can look at (Sgr A*, in the center of our galaxy) has an event horizon size of 50 as. For this kind of resolution roughly equivalent to trying to image a DVD on the Moon! wed need an Earth-sized telescope. EHT has solved this problem by linking telescopes around the world, creating one giant, mm-wavelength effective telescope with a baseline the size of Earth.Besides producing awesome images, the EHT will be able to test properties of black-hole spacetime, the no-hair theorem, and general relativity (GR) in new regimes.Ozel walked us through some of the theory prep work we need to do now in order to get the most science out of the EHT, including devising new tests of GR, and performing predictive GRMHD simulations hydrodynamics simulations that include magnetic fields and full GR treatment. Ozel pointed out that one of the recent theoretical advancements in GRMHD simulations is harnessing the power of GPUs to render images in simulations; check out the tweet below for the awesome video she showed us!Watch C. Chan manipulate black hole simulation with hand motions https://t.co/O5BgaltYAu (more on the code: https://t.co/9GC46ReMGs) #aas227 Sarah Scoles (@ScolesSarah) January 6, 2016Deployment of the full EHT array is planned for early 2017, and theyve already got 10 targets selected black holes that are near enough and large enough that the EHT should be able to image their shadows. I, for one, cant wait to see the first results!Grad School and Postdocs as a Means to a Job (by Meredith Rawls)This morning session was presented by Karen Kelsky of The Professor Is In. She presented a very practical overview of the advice in her book (which this job-searching Astrobiter highly recommends). Her target audience is postdocs and graduate students who are finishing their PhDs and applying for tenure-track jobs. Karens background is in the social sciences, but she has worked with many scientists and her expertise easily transferred. Much of her writing advice also applies for undergraduates who are writing research statements and proposals to apply to graduate school. For example:What not to do, with @ProfessorIsIn #aas227 pic.twitter.com/afGAsSuPwN Meredith Rawls (@merrdiff) January 6, 2016One of Karens main takeaways is that academia is not automatically good preparation for a job search. Writing documents like cover letters, resumes, and research statements will be harder and take more time than you think, and it is important to make them top-notch. Karen was also surprised that the majority of professional astronomers at the AAS meeting carry backpacks, because she typically advises against bringing a backpack to a job interview or campus visit. She conceded that astronomy is an exception to this rule!Brown Dwarfs and Exoplanets (by Caroline Morley)I started my morning in a session near and dear to my heart on brown dwarfs. The session had four dissertation talks, showcasing each students (impressive!) work over the last 4+ years.Astrobites alumnus Ben Montet kicked off the session to talk about his recent work to study the eclipsing brown dwarf LHS 6343, discovered in Kepler data. This brown dwarf is one of the best so-called benchmark brown dwarfs that we have discovered. Unlike almost every other object, we can measure LHS 6343s mass, radius, luminosity, and metallicity. Bens Spitzer observations reveal that its a ~1100 K T dwarf.Joe Filippazzo spoke next about his work to put together a large and impressive database of 300 brown dwarfs ranging in spectral type from M to Y, stitching together literature photometry, parallaxes, and both low and high resolution spectra. He studies the effect of age on the fundamental properties of these objects, empirically without needing models! You can download the database at BDNYC.org and use Joes open-source Python package astrokit which includes the SQL management tools to use the database.Jonathan Gagn presented results from his survey to find young free-floating objects in young moving groups. These objects are really interesting because they have the masses of planets but are easier to observe since they dont have nearby stars. He is currently extending his survey from his PhD thesis to be able to find even cooler objects (literally and figuratively) in these groups.Sebastian Pineda gave a very interesting talk about his thesis work to understand auroral emission from brown dwarfs. Brown dwarfs with a range of temperatures have been observed to have both radio activity and H-alpha emission, despite their neutral atmospheres. These properties are believed to be generated by auroral emission just like aurorae on Jupiter! One of many interesting results is that cooler objects have rare and weak aurorae. Sebastian postulates that these brown dwarfs may have aurorae that are modulated by the presence of satellites (brown dwarf moons?!). Very cool idea that needs more study!The last speaker of the session was the only non-dissertation talk of the session. Nolan Grieves presented results from his statistical survey of brown dwarf companions using the MARVELS radial velocity survey and finds a brown dwarf companion occurrence rate around 0.7%.Science to Action: Thoughts on Convincing a Skeptical Public (by Meredith Rawls)This years Public Policy plenary talk was delivered by William Press from UT Austin. Many scientific stories follow a familiar narrative, and too often, scientific consensus about a hazard has been accepted by the public only after some catalyzing event like a catastrophic fire or a spike in deaths linked to smoking. Press suggested that climate change may be at the tipping point of mainstream acceptance. He also discussed how a definition of science can encompass two distinct ideas: a series of fact-based conclusions and a value judgment based on rational thinking. To illustrate this dichotomy, he posed a question to the audience:Debate about science vs about values. Speaker forced a vote by raise of hand; split 50/50 in big room. Wow. #aas227 pic.twitter.com/rdvqUuuR95 Meredith Rawls (@merrdiff) January 6, 2016Press stated that he strongly supports the top view, but it was eye-opening to see a nearly even split of raised hands. His point was that GMO labeling ultimately boils down to a value judgement, not a scientific one, and we should be careful to understand the difference. Science communicators certainly have our work cut out for us! In the broadest sense, Press takeaway for effective science communication is a two-step approach: (1) communicate the value of a rationalist approach to decision making, and (2) communicate well-established scientific results.AAS Journals Workshop for Authors RefereesFirst half (by Susanna Kohler)Disclaimer: Im an employee of the AAS, as editor of AAS Nova.This 2-hour-long author referee workshop was intended partially as an overview of what it means to be an author or a referee (in any journal), and partly as a reveal of some of the new features that are now being implemented within the AAS publishing program. Many of the presentations have been uploaded here. A few highlights from the first half:Talks about authoring articles by Ethan Vishniac, and refereeing articles by Butler BurtonIntro to AAS Nova the AASs means of sharing its authors results with the broader community by me!Discussion of the AASs new policy for software citation by Chris LintottSecond half (by Becky Nevin)In between hopping between all the amazing science sessions today I made it to the last half of a very interesting Author Referee Workshop run by AAS journals. Even with missing the first half, I can still tell that theres a lot of changes coming to AAS journals (which include ApJ, AJ, ApJS, ApJL), in particular in the way that your research will be published. All good from what I saw in particular theyve addressed the long-standing problem of how to cite astronomical software (usually produced for free by a keen member of the community). Now they give guidelines for how to do this and have even appointed a new lead editor for instrumentation software.What got me most excited though was the demonstration by Greg Schwarz of AASTex v6.0 a markup package to assist authors in preparing manuscripts intended for submission to AAS-affiliated journals i.e. super cool amazing new LaTeX commands to satisfy even the most obsessive LaTeX-er! Check it out, because it will definitely ease the pain of writing and responding to referees. In the final talk (before free lunch, score!) Gus Muench showcased the new ways that authors will be able to include interactive JavaScript figures into articles in AAS journals. You can check out some of the amazing integrations in this nifty tutorial.A Report on the Inclusive Astronomy 2015 Meeting: Community Recommendations for Diversity and Inclusion in AstronomyThis very well-attended session recapped the Inclusive Astronomy 2015 meeting (see this link for a summary!)The IA2015 meeting results can be found here.A draft of the recommendations from IA2015 is here. Note that this document, termed the Nashville Recommendations, is a living document that isnt yet finalized, and feedback is welcome.Dannie Heineman Prize: From ~ to Precision Science: Cosmology from 1995 to 2025 (by Erika Nesvold)Marc Kamionkowski of Johns Hopkins University and David Spergel of Princeton University shared this years Heineman Prize for outstanding work in astronomy, and gave an impressive tag-team overview of the progress in the field of cosmology over the past 20 years.Spergel pointed out that in 1995, cosmologists were still debating over the value of the Hubble constant, and whether or not the universe is flat. Kamionkowski pointed out that back then, cosmology was an order of magnitude game where observations lagged far behind theory. He noted that in general, theorists tend to sit around predicting things, and not much progress is made in testing those predictions, at least not within the lifetime of an individual theorist. In cosmology, however, the measurements and observations made since 1995 have been more successful and precise than anyone could have anticipated.This is thanks in part to the WMAP mission and later the Planck satellite, which measured the cosmic microwave background and collected an amazing set of data. There is excellent agreement between the data from WMAP and Planck, a triumph for observational cosmologists. Much to the surprise of Spergel and other cosmologists, a simple model of only five fundamental parameters fits these data extremely well. Twenty years later, thanks to the hard work of cosmologists, we now know that the age of the universe is 13.8 billion years, and that it is composed of roughly 4% atoms, 23% dark matter, and 73% dark energy.Spergel and Kamionkowski then pointed towards the future, predicting even more spectacular results to come over the next decade or so. Our current model of the universe predicts gravitational waves, which we havent observed so far, but the search is heating up. Kamionkowski called this potentially the most important new physics result of this century! He also explained that we can now do neutrino physics using the cosmic microwave background, which already provides the strongest constraint on the sum of neutrinon masses. In the next decade, we should be able to further determine the neutrino mass hierarchy. The coming years in cosmology could be even more exciting than the past twenty!HEAD Rossi Prize talk: A New View of the High Energy Universe with NuSTAR (by Susanna Kohler)This years Rossi Prize winner Fiona Harrison capped off the main part of the day with a plenary talk about some of the highlights from the first two years of the NuSTAR mission, NASAs space-based, high-energy X-ray telescope.Additional science results from the past two years with NuSTAR.Harrison began by telling us about NuSTARs launch in 2012, in which a Pegasus rocket with NuSTAR as its payload was launched from a L-1011 Stargazer aircraft. She claims to have been unconcerned about this part: The payload would go up or it would go down, there wasnt anything I could do about it. The real terror for the NuSTAR team came 9 days later when the telescope slowly unfolded itself over the span of 24 minutes, snapping components into place. All went well, however, and NuSTAR has since been forging exciting new territory in the high-energy X-ray regime!Harrison discussed science highlights from the last two years of NuSTAR, like the discovery of a population of dead stars in the inner parsecs of the galaxy, the identification of the mechanism that most likely re-energizes stalled shocks in supernovae and launches the explosion (in case youre keeping track, its because the star sloshes around. Seriously.), or the evidence that supernova 1987A exploded asymmetrically.NuSTAR is funded through the end of 2016 and is now in its extended mission, so we can expect to see more exciting science coming from it in the future!

Thanks to all of you who stopped by we were delightedto have so many people tell us that they already know about and useastrobites, and we were excited to introduce a new cohort of students at AAS to astrobites for the first time.Tuesday morning was the official start of the meeting. Here are just a few of the talks and workshops astrobiters attended today.Opening Address (by Becky Smethurst)The President of the AAS, aka our fearless leader Meg Urry kicked off the meeting this morning at the purely coffee powered hour of 8am this morning. She spoke about the importance of young astronomers at the meeting (heres looking at you reader!) and also the importance of the new Working Group for Accessibility and Disabilities (aka WGAD pronounced like wicked) at the AAS. The Society has made extra effort this year to make the conference accessible to all,a message which was very well received by everyone in attendance.Kavli Lecture: New Horizons Alan Stern (by Becky Smethurst)We were definitely spoilt with the first Plenary lecture at this years conference Alan Stern gave us a a review of the New Horizons mission of the Pluto Fly By (astrobites covered the mission back in July with this post). We were treated to beautiful images, wonderful results and a foray into geology.Before (Hubble) and after #NewHorizons. #thatisall #science #astro alanstern #aas227 pic.twitter.com/kkMt6RsSIR Science News (@topsciencething) January 5, 2016Some awesome facts from the lecture that blew my mind:New Horizons is now 2AU (!) beyond PlutoThe mission was featured on the front pages of 450 newspapers worldwide on every single continent (including Antartica!)New Horizons reached the Moon in9 HOURSafter launch (compared to the ~3 days it took the Apollo missions)The mission controllers were aiming for a 100km window of space all the way from EarthThere was a window of ~400seconds which the probe had to arrive within the probe arrived90 seconds early! Putting tardy astronomers everywhere to shame.Charon was the only satellite of Pluto known at the time of the mission proposalThe canyon found on Charon is not only bigger than the Grand Canyon but bigger than Mariner Valley on Mars which is already4000 km (2500 mi) long and reaches depths of up to 7 km (4 mi)!Charons surface. Tectonic feature runs about 1500 km, around 10 km deep. Eat it, Mars. #aas227 pic.twitter.com/blewwJaXEn Danny Barringer (@HeavyFe_H) January 5, 2016The mountains ringing the Sputnik Planum (aka the heart of Pluto) are over 4km high and are snow capped with methane icePlutos mountain ranges.

As a parting gift Alan playedthemost gorgeously detailed fly over video of Plutos surface that had all in the room melting into their flip flops. Its safe to say that the whole room is now Pluto-curious and wondering whether a change of discipline is in order!Press Conference: Black Holes and Exoplanets (by Susanna Kohler)This morning marked the first press conference of the meeting, covering some hot topics in black holes and exoplanets.Hubble (background) and Chandra (purple) image of SDSS J1126+2944. The arrow marks the second black hole. (From http://casa.colorado.edu/~comerford/press)The first speaker was Julie Comerford (University of Colorado Boulder), who told us about SDSS J1126+2944, a galaxy that was shown by Chandra X-ray detections to contain not just one, but two supermassive black holes. This is a sign of a recent merger between two galaxies, which can result in one new, larger galaxy with two nuclei for a while. The second black hole is surrounded by only a small sphere of stars. This may be because the rest have been stripped away in the process of the merger but its also possible that the second black hole is an elusive intermediate mass black hole of only 100-1,000,000 solar masses! Heres the press release.The second speaker was Eric Schlegel (University of Texas, San Antonio), who spoke about the galaxy NGC 5195. Eric discussed an interesting problem: we know that star formation ends in galaxies after a time, but the gas must be cleared out of the galaxy for the star formation to halt. What process does this? Schlegels collaboration found evidence in NGC 5195 for a burping supermassive black hole the shock from the black holes outflow sweeps up the hydrogen gas and blows it out of the galactic center. Heres the press release.NuSTAR image of Andromeda, inset on a UV image by NASAs Galaxy Evolution Explorer. Click for a better look! [NASA/JPL-Caltech/GSFC]Next up was Daniel Wik (NASA/Goddard SFC), who discussed recent high-energy X-ray observations of Andromeda galaxy with NASAs NuSTAR. As Wik described it, NuSTAR is like a CSI detective, working to identify what fraction of the compact remnants in X-ray binaries of Andromeda are neutron stars, and what fraction are black holes. Since X-ray binaries play a crucial role in heating gas in protogalaxies, shaping galaxy formation, its important that we learn more about this population and how it evolves over time. Heres the press release.The final speaker was grad studentSamuel Grunblatt (University of Hawaii Institute for Astronomy), who spoke about measuring the mass of exoplanets around active stars. In radial velocity studies of exoplanets, a planet orbiting its star causes the star to wobble. This signal for an Earth-like planet is as tiny as 9 cm/s! Unfortunately, activity of the star can cause radial velocity noise of 1-10 m/s so to detect Earth-like planets, we need to find a way of subtracting off the noise. Grunblatt talked about an intriguing new method for determining planet masses that controls for the signature of their hosts activity. Heres his paper.Annie Jump Cannon Award Lecture: On the Dynamics of Planets, Stars and Black Holes (by Erika Nesvold)This year, the Annie Jump Cannon Award was given to Smadar Naoz, an assistant professor at UCLA. The Cannon Award is given every year to a young (less than 5 years since PhD), female astronomer for outstanding work in her field. Traditionally, the Cannon Award recipient delivers a lecture on her research, so this year we were lucky to see a dynamic and engaging talk by Smadar Naoz about her research in dynamical theory.You may have heard the common career advice that you should focus on becoming the expert on one particular facet of astronomy: a particular type of object, an observational technique, a type of instrument, etc. Naoz has managed to follow that advice while still managing to study a huge range of astronomical topics, from exoplanets to cosmology. She studies hierarchical triples, systems of three gravitational bodies in which two of the bodies orbit one another very closely, while the third orbits the other two from a much greater distance. For example, a planet in a tight orbit around a star, with a brown dwarf orbiting hundreds of AU away, make up a hierarchical triple system. So does a system in which two black holes orbit each other closely, with a third black hole orbiting farther away. The physics of these systems are all the same, so by studying the equations that govern a hierarchical triple system, Naoz can study a huge variety of astronomical objects.In particular, Naoz studies a mechanism called the Kozai-Lidov mechanism, named after the two researchers who discovered it independently. If the outer body in a hierarchical triple orbits at a high enough inclination to the inner body ( 40 degrees), the Kozai-Lidov mechanism will excite the inclination and eccentricity of the inner body. In fact, the inclination and eccentricity will oscillate opposite one another: as the inclination increases, the eccentricity will decrease, and vice versa. In the course of her research, Naoz discovered a flaw in Kozais original derivations of this mechanism, and derived a more accurate, general set of equations describing the Kozai-Lidov mechanism. These new equations indicate that the eccentricity of the inner object can become extremely high, and that the inclination can become so high that the objects orbit can flip from prograde to retrograde! In other words, the object can start orbiting in the opposite direction around the central body.Wondering how Naoz found the error in Kozai? I happen to know she rederives all the equations in every paper she reads. Wow. #aas227 Erika Nesvold (@erikanesvold) January 5, 2016This work has applications in many different types of systems. For example, over the past decade, observers have discovered a large number of retrograde hot Jupiters, gas giant planets orbiting very close to their star, in the opposite direction from the stars spin. Naoz showed that the new, correct Kozai-Lidov mechanism can explain the orbits of these exoplanets, because it increases the planets eccentricity until its orbit approaches very close to the star, and it flips the inclination into a retrograde orbit. Naoz: A puzzle: how to explain retrograde planets? Kozai mechanism can do that! #aas227 Peter Edmonds (@PeterDEdmonds) January 5, 2016Naoz also showed applications of the Kozai-Lidov mechanisms to dark matter halos around black holes, triple black hole systems, and so-called blue stragglers: main-sequence stars in clusters that are brighter and bluer than they should be. Her body of work is an excellent example of how theorists can adapt general physics theories to a wonderful variety of astronomical problems.holy styrofoam planets batman naoz just explained everything. #aas227 August Muench (@augustmuench) January 5, 2016Harassment in the Astronomical Sciences Town Hall(by Caroline Morley)The Town Hall on Harassment in the Astronomical Sciences involved a sobering panel discussion on the current state on workplace climate in astronomy and the current steps that the AAS and federal agencies are taking to improve it. Christina Richey kicked it off by presenting preliminary results from the CSWA Survey on workplace climate. This survey involved 426 participants, and reveals that many people, especially junior members of the field, experience harassment including both verbal and physical harassment. These results will be published this year. Next up, Dara Norman, a Councilor of the AAS and a member of the AAS Ethics Task Force, spoke about the proposed changes to the current AAS Ethics Statement. These changes will focus on corrective policies to improve the state of the field; they will solicit community feedback this Spring and vote on the changes at the Summer AAS meeting. Last, Jim Ulvestad, representing the federal agencies including NSF, NASA, and the DOE, spoke about the current policies for reporting to federal funding agencies. He reminds us that if an institution accepts money from the federal government, they are required by law to follow laws such as Title VI (covering racial harassment) and Title IX (covering sexual harassment), and that breaches can be reported to the funding agency.Tools and Tips for Better Software (aka Pain Reduction for Code Authors)(by Caroline Morley)This afternoon breakout session included a drinking-from-the-firehose set of short talks that covered everything from source-code management and software testing to building communities that create sustainable code. First, Kenza Arraki discussed software such as Git to do version control to keep track of code changes. (Version Control is my (science) New Years Resolution, so I was happy to learn that there is aCodeAcademy tutorial for Git!). Next up, AdrianPrice-Whelan described the merits of software testing and suggests that we actually do Test-driven development where we write tests for the code first, then write code, run tests and debug until tests all pass. Erik Tollerud spoke on Why Document code and how you might convince yourself to do so (documenting code is another good science New Years Resolution!) The most important rule is to always document as you code because you wont ever go back! Bruce Berriman described the best practices for code release, including, importantly, licensing it and describing it well (with tutorials, examples). Matthew Turk reminded us the importance of building community around code development. Robert Nemiroff ended the talks with a discussion of what to do withdeadcodes. The lowest bar? Put it in your Dropbox and share it with your collaborators and students!For more info on all of these topics and more, consider attending a Software Carpentry workshop.

  16. Between-day reliability of centre of pressure measures for balance assessment in hemiplegic stroke patients

    PubMed Central

    2014-01-01

    Background Stroke patients have impaired postural balance that increases the risk of falls and impairs their mobility. Assessment of postural balance is commonly carried out by recording centre of pressure (CoP) displacements, but the lack of data concerning reliability of these measures compromises their interpretation. The purpose of this study was to investigate the between-day reliability of six CoP-based variables, in order to provide i) reliability data for monitoring postural sway and weight-bearing asymmetry of stroke patients in clinical practice and ii) consistent assessment method of measurement error for applications in physical medicine and rehabilitation. Methods Postural balance of 20 stroke patients was assessed in quiet standing on a force platform, in two sessions, 7 days apart. Six CoP-based variables were collected in eyes open and eyes closed conditions: postural sway was assessed with mean and standart deviation of CoP-velocity, CoP-velocity along the mediolateral and anteroposterior axes, and confidence ellipse area (CEAREA); weight-bearing asymmetry was assessed with mean CoP position along the mediolateral axis (CoPML). The intraclass correlation coefficient (ICC) was used to determine the level of agreement between test-retest. Small real difference (SRD), corresponding to the smallest change that indicates a real improvement for a single individual, was used to determine the extent of measurement error. Results ICCs were satisfactory (>0.9) for all CoP-based variables, except for CEAREA in eyes open condition and CoPML (<0.8). The SRDs (eyes open/closed conditions) were: 6.1/9.5 mm.s-1 for mean velocity; 12.3/12.2 mm.s-1 for standard deviation of CoP-velocity; 3.6/5.5 mm.s-1 and 4.9/7.3 mm.s-1 for CoP-velocity in mediolateral and anteroposterior axes, respectively; 17.4/21.4 mm for CoPML. Because CEAREA showed heteroscedasticity of measurement error distribution, SRD (eyes open/closed conditions) was expressed as a percentage (121/75%) and a ratio (3.68/2.16) obtained after log-antilog procedure. Conclusions In clinical practice, the CoP-based velocity variables should be prefer to CEAREA to assess and monitor postural sway over time in hemiplegic stroke patients. The poor reliability of CoPML compromises its use to assess weight-bearing asymmetry. The procedure we used could be applied in reliability studies concerning other CoP-based variables or other biological variables in the field of physical medicine and rehabilitation. PMID:24649845

    Rottger, J.

    1983-01-01

    A method for processing complex radar data with a computer using correlation functions is reviewed. Parameters including data storage, data reduction, and real time operation are addressed. Since complex auto- and cross-correlation functions are calculated and stored, almost no information is lost. These also can be analyzed in terms of the full correlation analysis of the spaced-antenna-drifts technique. The proposed approach therefore appears to be very feasible to suit most Mesosphere-Stratosphere-Troposphere (MST) radar applications.

  6. The observed day-to-day variability of Mars water vapor

    NASA Technical Reports Server (NTRS)

    Jakosky, Bruce M.; Lapointe, Michael R.; Zurek, Richard W.

    1987-01-01

    The diurnal variability of atmospheric water vapor as derived from the Viking MAWD data is discussed. The detection of day to day variability of atmospheric water would be a significant finding since it would place constraints on the nature of surface reservoirs. Unfortunately, the diurnal variability seen by the MAWD experiment is well correlated with the occurrence of dust and/or ice hazes, making it difficult to separate real variations from observational effects. Analysis of the day to day variability of water vapor in the Martian atmosphere suggests that the observations are, at certain locations and seasons, significantly affected by the presence of water-ice hazes. Because such effects are generally limited to specific locations, such as Tharsis, Lunae Planum, and the polar cap edge during the spring, the seasonal and latitudinal trends in water vapor that have been previously reported are not significantly affected.

    Variability in airway function may be a marker of disease activity in COPD and asthma. The aim was to determine the effects of repeatability and airway obstruction on day-to-day variability in respiratory system resistance (Rrs) and reactance (Xrs) measured by forced oscillation technique (FOT). Three groups of 10 subjects; normals, stable asthmatic and stable COPD subjects underwent daily FOT recordings for 7 days. Mean total and inspiratory Rrs and Xrs, and expiratory flow limitation (EFL) Index (inspiratory - expiratory Xrs), were calculated. The ICC's were high for all parameters in all groups. Repeatability, in terms of absolute units, correlated with airway obstruction and was therefore lowest in COPD. Day-to-day variability was due mostly to repeatability, with a small contribution from the mean value for some parameters. FOT measures are highly repeatable in health, stable asthma and COPD in relation to the wide range of measures between subjects. For home monitoring in asthma and COPD, either the coefficient of variation or individualized SDs could be used to define day-to-day variability. PMID:22960661

    For more than half a century, the 1959 Antarctic Treaty continues to shine as a rare beacon of international cooperation. To celebrate this milestone of peace in our civilization with hope and inspiration for future generations, Antarctica Day is celebrated each year on December 1st , the anniversary of the Antarctic Treaty signing. As an annual event - initiated by the Foundation for the Good Governance of International Spaces (www.internationalspaces.org/) in collaboration with the Association of Polar Early Carer Scientists (www.apecs.is) - Antarctica Day encourages participation from around the world. The Antarctic Treaty set aside 10% of the earth, 'forever to be used exclusively for peaceful purposes in the interest of mankind.' It was the first nuclear arms agreement and the first institution to govern all human activities in an international region beyond sovereign jurisdictions. In this spirit, Antarctica Day aims to: - Demonstrate how diverse nations can work together peacefully, using science as a global language of cooperation for decision making beyond national boundaries, - Provide strategies for students learning about Antarctica through art, science and history at all school levels, - Increase collaboration and communication between classrooms, communities, researchers and government officials around the world, and - Provide a focus for polar educators to build on each year. Through close collaboration with a number of partners. Antarctica Day activities have included: a Polar Film Festival convened by The Explorers Club; live sessions connecting classrooms with scientists in Antarctica thanks to PolarTREC and ARCUS; an international activity that involved children from 13 countries who created over 600 flags which exemplify Antarctica Day (these were actually flown in Antarctica with signed certificates then returned to the classes); a map where Antarctica Day participants all over the world could share what they were doing; an Antarctic bird count involving the International Association of Antarctic Tour Operators; and public lectures and online videos (including a notable submission from Polar Educators International). Antarctica Day was initiated as a legacy of the 2009 Antarctic Treaty Summit (www.atsumit50.aq), which was convened at the Smithsonian Institution with 40 sponsoring institutions from around the world as part of the International Polar Year. Antarctic Day involved participants from 14 nations in 2010. 28 nations in 2011, and 26 nations in 2012 with representatives from all 7 continents. Antarctica Day 2013 will have recently taken place before the AGU Fall Meeting 2013, and we will present updates at that time. Our aim is to continue expanding Antarctica Day as a globally-accessible platform to share, interpret and cherish the values associated with Antarctica for the benefit of present and future generations. We look forward to the discussion and sharing that this session will provide.

    Increasingly researchers are looking to bring together perspectives across multiple scales, or to combine insights from different techniques, for the same region of interest. To this end, correlative microscopy has already yielded substantial new insights in two dimensions (2D). Here we develop correlative tomography where the correlative task is somewhat more challenging because the volume of interest is typically hidden beneath the sample surface. We have threaded together x-ray computed tomography, serial section FIB-SEM tomography, electron backscatter diffraction and finally TEM elemental analysis all for the same 3D region. This has allowed observation of the competition between pitting corrosion and intergranular corrosion at multiple scales revealing the structural hierarchy, crystallography and chemistry of veiled corrosion pits in stainless steel. With automated correlative workflows and co-visualization of the multi-scale or multi-modal datasets the technique promises to provide insights across biological, geological and materials science that are impossible using either individual or multiple uncorrelated techniques.

    With the development of Astronautics very large projects become possible. The Moon-Day project comes from a simple idea: 2000 km 2 of mirrors on the Moon reflecting the solar light toward the Earth will make it possible to turn off street lighting during the Moon nights. With more mirrors it is even possible to produce a "moon-day" similar to the light at sunrise or sunset, that will be a great improvement on the quality of life, especially in tropical and equatorial countries where people, and above all farmers, will have the possibility to work during the cool night hours instead of the exhausting day hours. Comparison with mirrors on a geostationary orbit shows the many advantages of the mirrors on the Moon.

    2016-06-01

    A single trait linear mixed random regression test-day model was applied for the first time for analyzing the first lactation monthly test-day milk yield records in Karan Fries cattle. The test-day milk yield data was modeled using a random regression model (RRM) considering different order of Legendre polynomial for the additive genetic effect (4th order) and the permanent environmental effect (5th order). Data pertaining to 1,583 lactation records spread over a period of 30 years were recorded and analyzed in the study. The variance component, heritability and genetic correlations among test-day milk yields were estimated using RRM. RRM heritability estimates of test-day milk yield varied from 0.11 to 0.22 in different test-day records. The estimates of genetic correlations between different test-day milk yields ranged 0.01 (test-day 1 [TD-1] and TD-11) to 0.99 (TD-4 and TD-5). The magnitudes of genetic correlations between test-day milk yields decreased as the interval between test-days increased and adjacent test-day had higher correlations. Additive genetic and permanent environment variances were higher for test-day milk yields at both ends of lactation. The residual variance was observed to be lower than the permanent environment variance for all the test-day milk yields. PMID:26954137

  17. Correlative microscopy.

    PubMed

    Loussert Fonta, Céline; Humbel, Bruno M

    2015-09-01

    In recent years correlative microscopy, combining the power and advantages of different imaging system, e.g., light, electrons, X-ray, NMR, etc., has become an important tool for biomedical research. Among all the possible combinations of techniques, light and electron microscopy, have made an especially big step forward and are being implemented in more and more research labs. Electron microscopy profits from the high spatial resolution, the direct recognition of the cellular ultrastructure and identification of the organelles. It, however, has two severe limitations: the restricted field of view and the fact that no live imaging can be done. On the other hand light microscopy has the advantage of live imaging, following a fluorescently tagged molecule in real time and at lower magnifications the large field of view facilitates the identification and location of sparse individual cells in a large context, e.g., tissue. The combination of these two imaging techniques appears to be a valuable approach to dissect biological events at a submicrometer level. Light microscopy can be used to follow a labelled protein of interest, or a visible organelle such as mitochondria, in time, then the sample is fixed and the exactly same region is investigated by electron microscopy. The time resolution is dependent on the speed of penetration and fixation when chemical fixatives are used and on the reaction time of the operator for cryo-fixation. Light microscopy can also be used to identify cells of interest, e.g., a special cell type in tissue or cells that have been modified by either transfections or RNAi, in a large population of non-modified cells. A further application is to find fluorescence labels in cells on a large section to reduce searching time in the electron microscope. Multiple fluorescence labelling of a series of sections can be correlated with the ultrastructure of the individual sections to get 3D information of the distribution of the marked proteins: array tomography. More and more efforts are put in either converting a fluorescence label into an electron dense product or preserving the fluorescence throughout preparation for the electron microscopy. Here, we will review successful protocols and where possible try to extract common features to better understand the importance of the individual steps in the preparation. Further the new instruments and software, intended to ease correlative light and electron microscopy, are discussed. Last but not least we will detail the approach we have chosen for correlative microscopy. PMID:26072116

    A correlation spectrometer can detect a large number of gaseous compounds, or chemical species, with a species-specific mask wheel. In this mode, the spectrometer is optimized for the direct measurement of individual target compounds. Additionally, the spectrometer can measure the transmission spectrum from a given sample of gas. In this mode, infrared light is passed through a gas sample and the infrared transmission signature of the gasses present is recorded and measured using Hadamard encoding techniques. The spectrometer can detect the transmission or emission spectra in any system where multiple species are present in a generally known volume.

    Landfills reaching capacity, beaches fouled with trash, neighborhood residents protesting waste disposal sites in their backyards, and municipalities forced to recycle. Sound familiar? These issues might have been taken from today`s headlines, but they were also problems facing mechanical engineers a century ago. Conditions such as these were what led engineers to design the first incinerators for reducing the volume of municipal garbage, as well as for producing heat and electricity. The paper discusses these early days.

    On this ninth day of the STS-79 mission, the flight crew, Cmdr. William F. Readdy, Pilot Terrence W. Wilcutt, Mission Specialists, Thomas D. Akers, Shannon Lucid, Jay Apt, and Carl E. Walz having completed five days of joint operations between the American astronauts and the Russian cosmonauts are seen flying solo once again after undocking from the Mir Space Station. As Atlantis/Mir flew over the Ural Mountains of central Asia, the docking hooks and latches that joined the vehicles together were commanded open and Atlantis drifted slowly away from Mir. Wilcutt then initiated a tail-forward fly-around of the Russian space station. After one and one-half revolutions around Mir, Atlantis' jets were fired in a separation maneuver to enable Atlantis to break away from Mir. On board Atlantis, the six-member crew is settling back into its normal routine with a fairly light schedule for the remainder of the day. Early in the morning as Atlantis flew over the United States, the crew took time to talk with anchors for the CBS Up to the Minute' network news broadcast.

  4. Encapsulated radiophosphorescent standards for day-to-day photometer calibration.

    O'Kane, D J; Lee, J

    1990-10-01

    Solid, unquenched, radiophosphorescent standards for use in the day-to-day calibration of bottom viewing photometers (luminometers) were prepared by encapsulating commercially-available phosphor powders that are excited to phosphoresce by the beta- decay of 63Ni (t0.5 = 96 yr) or 14C (t0.5 = 5730 yr). The radionuclides are physically adsorbed on the phosphors by precipitation either as a "basic nickel carbonate" or as barium carbonate. The radioactive phosphors are then deposited by centrifugation as a thin layer at the bottom of the vials or tubes that are normally used in the photometer. The phosphor layer is infiltrated with a plastic resin and embedded. A light absorbing layer is subsequently cast over the phosphor layer to prevent stray light excitation of phosphorescence. The encapsulated photometer standards have remained mechanically and photometrically stable since their fabrication, which in some cases is 3 years ago. An equivalent level of visible luminescence emitted from the standards of up to 2.3 x 10(10) photons.s-1 was achieved by using an appropriate amount of radioactivity and the proper phosphor. The phosphor used in the standards could be chosen such that the radiophosphorescence emission spectrum corresponded approximately to the chemiluminescence or bioluminescence spectrum under investigation.

  5. Macrocognition in Day-To-Day Police Incident Response

    2016-01-01

    Using examples of incidents that UK Police Forces deal with on a day-to-day basis, we explore the macrocognition of incident response. Central to our analysis is the idea that information relating to an incident is translated from negotiated to structured and actionable meaning, in terms of the Community of Practice of the personnel involved in incident response. Through participant observation of, and interviews with, police personnel, we explore the manner in which these different types of meaning shift over the course of incident. In this way, macrocognition relates to gathering, framing, and sharing information through the collaborative sensemaking practices of those involved. This involves two cycles of macrocognition, which we see as ‘informal’ (driven by information gathering as the Community of Practice negotiates and actions meaning) and ‘formal’ (driven by the need to assign resources to the response and the need to record incident details). The examples illustrate that these cycles are often intertwined, as are the different forms of meaning, in situation-specific ways that provide adaptive response to the demands of the incident.

    2007-10-01

    The Cassini Mission's "Scientist for a Day" program allows students the opportunity to be in scientists' shoes, evaluate various options and learn how to make decisions based on scientific value. Students are given three or more possible imaging targets. They research these targets and decide which one will bring the best scientific results. They then defend their choice in a 500-word essay. The essay with the best scientific argument for a chosen target wins the contest. Cassini will take the images on Nov. 30, 2007. A few days later, winners (and as many other students as possible) are invited to discuss the results with Cassini scientists via videoconferences. Entries are judged by a committee composed of Cassini scientists, Cassini mission planners, Cassini Outreach and JPL Education Specialists. The contest has been held on a smaller scale three times. This edition is open to all U.S. schools. Students will be divided in two groups, grades 5 to 8 and grades 9 to 12. The contest will also be held in England, and possibly in other countries.

Hire, and Payload Specialists Jay C. Buckey and James A. Pawelczyk focus on the efforts of Neurolab's Neuronal Plasticity Team to better understand how the adult nervous system adapts to the new environment of space. Columbia's science crew -- Mission Specialists Rick Linnehan and Dave Williams and Payload Specialists Jay Buckey and Jim Pawelczyk -- perform the second and final in-flight dissections of the adult male rats on board. The crew euthanizes and dissects nine rats and remove the vestibular or balance organs of the inner ear; the cerebellum, the part of the brain critical for maintaining balance and for processing information from the limbs so they can be moved smoothly; and the cerebrum, one part of which controls automatic functions such as body temperature regulation and the body's internal clock, and the cortical region that controls cognitive functions such as thinking. The first dissection, which was performed on the second day of the flight, went extremely well, according to Neurolab scientists.

    Day hospitals provide an organizational framework for complex psychiatric and psychotherapeutic treatments. They have been developed regarding treatment and in number, perhaps surprisingly, to fit existing standards in almost all domains of psychiatry. Similarities exist in the emphasis on acute treatment, in the orientation towards social inclusion, and particularly in the ability to connect with previous treatment settings. Day treatment guidelines exist only in basic form. In general the complex outpatient treatment is led by psychiatrists; the treatment is planned and pre-defined regarding time and goal orientation. It is directed exclusively at patients with severe mental health disorders and practiced by a multi-professional team. A structured treatment milieu is likely to be the main ingredient which includes all somatic-biological and many psychotherapeutic methods. Special options that for the most part have been empirically validated are available for the treatment of post-acute patients, prevention of social exclusion from families and work, detoxification of addicts and psychotherapy of personality disorders. The rapid increase of facilities is expected to persist for some time. Scientific evidence is relatively strong. Given proper indication, financial resources are used with a high degree of efficiency. PMID:20119657

  11. First Complete Day from MODIS

    2002-01-01

    This spectacular, full-color image of the Earth is a composite of the first full day of data gathered by the Moderate-resolution Imaging Spectroradiometer (MODIS) aboard NASA's Terra spacecraft. MODIS collected the data for each wavelength of red, green, and blue light as Terra passed over the daylit side of the Earth on April 19, 2000. Terra is orbiting close enough to the Earth so that it cannot quite see the entire surface in a day, resulting in the narrow gaps around the equator. Although the sensor's visible channels were combined to form this true-color picture, MODIS collects data in a total of 36 wavelengths, ranging from visible to thermal infrared energy. Scientists use these data to measure regional and global-scale changes in marine and land-based plant life, sea and land surface temperatures, cloud properties, aerosols, fires, and land surface properties. Notice how cloudy the Earth is, and the large differences in brightness between clouds, deserts, oceans, and forests. The Antarctic, surrounded by clockwise swirls of cloud, is shrouded in darkness because the sun is north of the equator at this time of year. The tropical forests of Africa, Southeast Asia, and South America are shrouded by clouds. The bright Sahara and Arabian deserts stand out clearly. Green vegetation is apparent in the southeast United States, the Yucatan Peninsula, and Madagascar. Image by Mark Gray, MODIS Atmosphere Team, NASA GSFC

    The idea of Earth Day 1970 was to have a national demonstration of environmental concern big enough to shake up the political establishment--get its attention, get some action, force environmental issues onto the political agenda of national priorities. The idea worked, thanks to the spontaneous response of millions of concerned Americans, and the event served as a wake-up call to the political establishment. Suddenly, the environment became a national political priority. Since Earth Day 1970, Congress has enacted nearly 40 major federal environmental laws addressing a wide range of issues, including clean air, clean water, energy conservation, hazardous wastes, and herbicides and other pesticides. Dozens of individual public land bills have been enacted since 1970 to designate or expand wilderness areas, wild and scenic rivers, national parks, and wildlife refuges. Perhaps most important, more than 80 percent of Americans now regard themselves as environmentalists. Since 1970 man has come a long way. After 25 years of researching, debating, and learning, increasing numbers of people recognize that the state of the environment is the key factor in determining this way of life and the quality of it.

    2012-01-01

    Using nine new taxa and statistical inferences based on morphological and molecular data, we analyze the evolution within the class Colpodea. The molecular and cladistic analyses show four well-supported clades: platyophryids, bursariomorphids, cyrtolophosidids, and colpodids. There is a widespread occurrence of homoplasies, affecting even conspicuous morphological characteristics, e.g. the inclusion of the micronucleus in the perinuclear space of the macronucleus. The most distinct changes in the morphological classification are the lack of a basal divergence into two subclasses and the split of the cyrtolophosidids into two main clades, differing mainly by the presence vs. absence of an oral cavity. The most complex clade is that of the colpodids. We partially reconcile the morphological and molecular data using evolutionary systematics, providing a scenario in which the colpodids evolved from a Bardeliella-like ancestor and the genus Colpoda performed an intense adaptive radiation, giving rise to three main clades: Colpodina n. subord., Grossglockneriina, and Bryophryina. Three new taxa are established: Colpodina n. subord., Tillinidae n. fam., and Ottowphryidae n. fam. Colpodean evolution and classification are far from being understood because sequences are lacking for most species and half of their diversity is possibly undescribed. PMID:21762424

Hire, and Payload Specialists Jay C. Buckey and James A. Pawelczyk turns its attention to dexterity tests and dissections of rats neonates and the ball-catch experiment. Mission Specialists Rick Linnehan and Dave Williams and Payload Specialist Jim Pawelczyk will dissect the newborn rats. The dexterity test will test the response of young rats as they are tilted and turned while walking and climbing on a special apparatus with various surfaces. Later, all four payload crew members will repeat the ball-catch experiment. This experiment studies the ability of the central nervous system to accept and interpret new stimuli in space. The astronauts have performed this test at various points in the mission so scientists can compare their responses as their bodies adapt to weightlessness.

    Ladd, Amy L; Messana, Joseph; Berger, Aaron J.; Weiss, Arnold-Peter C.

    2014-01-01

    Purpose To determine if a slight modification of the 1987 Eaton-Glickel staging and interpreting 4 standardized radiographs for trapeziometacarpal arthritis improved analysis, to determine if a quantifiable index measurement from a single Robert (pronated anteroposterior) view enhanced reproducibility, and to examine whether improved radiographic staging correlated to clinically relevant disease and thus support validity. Methods We analyzed 4 thumb radiographs (posteroanterior, lateral, a Robert, and stress views) in 60 consecutive subjects representing an adult population spectrum of asymptomatic to advanced disease. Two experienced hand surgeons, 1 chief resident, and 1 medical student performed the analysis on each subject’s radiographs. We analyzed all 4 radiographs for Eaton and modified Eaton staging and then later analyzed only the Robert view for the thumb osteoarthritis (ThOA) index measurement. The radiographs were randomized and re-read a week later for each classification at separate times. Surgically excised trapeziums from 20/60 subjects were inspected for first metacarpal surface disease and correlated to the 3 classifications. Results All 3 staging classifications demonstrated high reproducibility, with the intraclass correlation coefficient averaging 0.73 for the Eaton, 0.83 for the modified Eaton, and 0.95 for the ThOA index. Articular wear and metacarpal surface eburnation correlated highest to the ThOA index, with advanced disease ≥ 1.55 correlating to Eaton III/IV and modified Eaton stage 3/4 in a linear relationship. Discussion The ThOA index based on a Robert view provided a measurable alternative to Eaton staging and correlated to severity of surgically relevant thumb TMC OA. Clinical Relevance A simple reproducible radiographic measurement may enhance TMC OA classification and provide a reliable means to predict clinical disease.

    [figure removed for brevity, see original site] Annotated Version

    The Day fire has been burning in Ventura County in Southern California since Labor Day, and has consumed more than 160,000 acres. As of September 29, it was 63 percent contained. The Advanced Spaceborne Thermal Emission and Reflection Radiometer on NASA's Terra satellite flew over the fire at 10 p.m. Pacific Time on September 28, and imaged the fire with its infrared camera. The hottest areas of active burning appear as red spots on the image. The blue-green background is a daytime image acquired in June, used as a background to allow firefighters to localize the hot spots.

    With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet.

    ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.

    The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping, and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

    The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission directorate.

Hire, and Payload Specialists Jay C. Buckey and James A. Pawelczyk continue work with the Escher Staircase Behavior Testing of Adult Rats experiment. This is the first of two behavior testing sessions with the adult rats being used for this experiment. The rats will have a 'hyper drive' unit placed on their head which has recording electrodes made of microscopic wires that are positioned in the brain to record activity in the hippocampus. The hippocampus is that portion of the brain used to develop spatial maps to help us navigate from one place to the other. With the 'hyper drive' units in place, the rats will then be put through a maze or on a track. While the rat is maneuvering on the maze or track, the cell activity of the hippocampus will be measured and recorded.

  4. The day of the yam.

    PubMed

    Rosser, A

    Yam, the staple food in several tropical countries, is a good source of the steroid used in the manufacture of the pill and other sex hormone preparations -- saponin diosgenin. In the early days of production of oral contraceptives (OCs), most yams were gathered from the wild in Mexico. The type richest in steroids takes 3 years to mature and its cultivation has become something of an art. Yams grow best in light, well-drained soil, and for this reason are grown in mounds which have been heavily manured. Propagation is by planting the tops or heads or by small portions of the tuber which is a swollen shoot. Other varieties are planted before the onset of the rains and the crop harvested about 8 months later. In 1970 the Mexican government nationalized the yam industry as a safeguard. This pushed up prices and the drug companies looked elsewhere for a cheap source. Although Mexico still remains the principal grower, India, South Africa, and the Far East supply the industry with plant origin steroids. As more than 90% of the hefty yam tubers consist of water, well over 100,000 tons have to be harvested every year to provide the 600-700 tons of the saponin diosgenin used by the drug companies. In China, where Western corticosteroids are regarded as too expensive for the barefoot doctors, several species of yam are used. Research has been going on to find another source of diosgenin and the most promising seems to be fenugreek, Trigonella foenumgraecum. "Foenum graecum" is Latin for Greek hay and was used by the early Greeks as a culinary and medicinal herb throughout the Mediterranean area. The richness of fenugreek was used to improve the roundness of women's breasts and to stimulate the flow of milk. Bath University has spent 10 years researching the development of a species of fenugreek which will yield large amounts of diosgenin. A certain amount of steroids come from animal sources. Such steroids are given when there is an adverse reaction from the administeration of the synthetic variety. Placentae are a rich source of steroids and have been found to contain hormones, minerals, and enzymes. Placentae now are becoming big business throughout Europe. Although it is possible to make OCs from placental extract, it is not commercially viable. Over 600 varieties of yam exist and at this time there is no danger of the supply running out. PMID:3846954

    2012-09-01

    Models of day services for people with intellectual disabilities in Scotland are changing, with the purpose, content and availability being reviewed. There has been concern that a move to more flexible 'alternative day opportunities' is driven more by reduced budgets than a policy of modernising day services in response to individual needs. During a day services review, a questionnaire was used to rate and to collect views on existing services from 60 carers, service users and staff. This included evaluating day activities available, care plans, opening times, transport and the most valued aspects of existing day services. Respondents indicated general satisfaction with existing day services, although half believed that day services should be reviewed. The most valued parts of day services were forming and building friendships, and a safe place to go. Day services are highly valued by families and service users. Recommendations are made for a robust and transparent review process. PMID:22843810

    Describes a technique for obtaining the quiet-time geomagnetic field variation expected for all days of the year and distribution of latitudes from a limited set of selected quiet days within a year at a discrete set of locations. A data set of observatories near 75??E longitude was used as illustration. The method relies upon spatial smoothing of the decomposed spectral components. An evaluation of the fidelity of the resulting model shows correlation coefficients usually above 0.9 at the lower latitudes and near 0.7 at the higher latitudes with variations identified as dependent upon season and field element. -from Authors

  11. Reliability and validity of the modified child and adolescent physical activity and nutrition survey (CAPANS-C) questionnaire examining potential correlates of physical activity participation among Chinese-Australian youth

    PubMed Central

    2014-01-01

    Background To date, few questionnaires examining psychosocial influences of physical activity (PA) participation have been psychometrically tested among Culturally and Linguistically Diverse (CALD) youth. An understanding of these influences may help explain the observed differences in PA among CALD youth. Therefore, this study examined the reliability and predictive validity of a brief self-report questionnaire examining potential psychological and social correlates of physical activity among a sample of Chinese-Australian youth. Methods Two Chinese-weekend cultural schools from eastern metropolitan Melbourne consented to participate in this study. In total, 505 students aged 11 to 16 years were eligible for inclusion in the present study, and of these, 106 students agreed to participate (21% response rate). Participants completed at 37-item self-report questionnaire examining perceived psychological and social influences on physical activity participation twice, with a test–retest interval of 7 days. Predictive validity, internal consistency and test–retest reliability were evaluated using exploratory factor analyses, Cronbach’s α coefficient, and the intraclass correlation coefficient (ICC) respectively. Predictive validity was assessed by correlating responses against duration spent in self-reported moderate-to-vigorous physical activity (MVPA). Results The exploratory factor analysis revealed a nine factor structure, with the majority of factors exhibiting high internal consistency (α ≥ 0.6). In addition, four of the nine factors had an ICC ≥ 0.6. Spearman rank-order correlations coefficients between the nine factors and self-reported minutes spent in MVPA ranged from -0.5 to 0.3 for all participants. Conclusion This is the first study to examine the psychometric properties of a potential psychological and social correlates questionnaire among Chinese-Australian youth. The questionnaire was found to provide reliable estimates on a range of psychological and social influences on physical activity and evidence of predictive validity on a limited number of factors. More research is required to improve the reliability and validity of the questionnaire. PMID:24512223

  12. Analysis of the dual discrimination ability of the two-port photorefractive joint transform correlator.

    1995-12-10

    An all-optical joint transform correlator featuring two operative correlation planes(ports) with complementary performance is presented. We present the theory of operation, derive the input-output characteristics, and demonstrate computer simulations and experimental results. The two-port joint transform correlator is based on simultaneous use of two photorefractive wave-mixing architectures. The first port uses two-beam coupling, and the second port uses four-wave mixing. The performance of the two ports depends on an experimentally controlled beam intensity ratio and the photorefractive coupling coefficient. With appropriate selection of these parameters, the first port is capable of high discrimination, while simultaneously the second offers a low discrimination output. Our results show that the two-beam coupling port can achieve peak-to-noise and signal-to-noise ratio values better than the phase-only correlator, whereas the four-wave-mixing port performs similarly to the classical joint transform correlator. This leads to a potential application in which the correlator could be set up so that in one port a general class is detected (interclass) and, in the other, the specific item in a class is detected (intraclass).

  13. Effect of maternal and infant covariates on sibship correlation in birth weight.

    1988-01-01

    Birth weight on 12,644 singleton infants from 6,196 sibships born in Maryland between 1980 and 1984 were used to estimate the effects of nine maternal and infant covariates on the sibship correlation in birth weight. Assuming a homogeneous correlation across all families, the estimated intraclass correlation was 0.4664 (+/- 0.0099). This high sibship correlation makes it possible to predict, with reasonable accuracy, the birth weight of a child given information on previous sibs, as well as covariates on the mother and/or infant pertinent to a given pregnancy. The reduction in variance associated with incorporating information on the nine covariates used here was approximately equal to that obtained by conditioning on a single previous sib. Testing for heterogeneity in correlation among different groups of families showed that a crude measure of parity (first live birth vs. other), time between births, mother's marital status, and maternal age at the birth of the last child significantly influenced the sibship correlation in birth weight.

    Subjects judged the time-course of the burn caused by 100 ppm capsaicin applied to the tongue on Day 1 and Day 5. On Days 2-4, they tasted hard candy containing capsaicin. Most subjects did not show adaptation within Day 1, but either plateaued after about 16 min or rose monotonically for the entire 34 min. Intensity was less on Day 5 and levelled off or declined for most subjects. Data were fit to a mathematical model of adaptation. Adaptation across days was accounted for by changes in the gains of the three processes. PMID:9035246

    The Murchison Widefield Array is a Square Kilometre Array Precursor. The telescope is located at the Murchison Radio-astronomy Observatory in Western Australia. The MWA consists of 4 096 dipoles arranged into 128 dual polarisation aperture arrays forming a connected element interferometer that cross-correlates signals from all 256 inputs. A hybrid approach to the correlation task is employed, with some processing stages being performed by bespoke hardware, based on Field Programmable Gate Arrays, and others by Graphics Processing Units housed in general purpose rack mounted servers. The correlation capability required is approximately 8 tera floating point operations per second. The MWA has commenced operations and the correlator is generating 8.3 TB day-1 of correlation products, that are subsequently transferred 700 km from the MRO to Perth (WA) in real-time for storage and offline processing. In this paper, we outline the correlator design, signal path, and processing elements and present the data format for the internal and external interfaces.

    Based on the concept of somatization, psychological distress can be experienced as symptoms of physical illness. This suggests a close-fitting intra-individual association between bodily complaints and mood in patients with somatoform disorder (SFD). The contemporaneous day-to-day complaints-mood association was investigated in patients with severe chronic SFD using an ecological momentary assessment (EMA) design. Eleven patients, who had recently received specialized tertiary care treatment for severe chronic SFD, kept an online electronic diary for four consecutive weeks. They were prompted at intervals throughout the day to complete questions on their momentary primary symptoms (pain and fatigue), and mood state (negative and positive). For each measure, day-mean aggregated values were computed and analyzed using linear multilevel (mixed model) regression analysis. Fixed factor results showed that symptoms were associated with both negative mood state (β = 0.47) and positive mood state (β = -0.59). Random results, however, indicated large inter-individual differences, with correlations varying between 0.17 and 0.99 for negative affect, and between -0.88 and 0.14 for positive affect. A substantial day-to-day contemporaneous association between symptoms and affect across subjects, as well as large inter-individual differences in this association, were demonstrated in patients with severe chronic SFD. EMA-data showing the relationship between both negative and (inverse) positive mood and complaints has potential clinical relevance: providing SFD patients with feedback consisting of their personal day-to-day concurrency graph may promote their understanding of their own complaints in a broader context than the somatic area.

    2004-06-01

    Changes in annual, June-September and March-May rainfall and rainy days herein (defined as a day with rainfall greater than 1 mm) have been analysed based on 11 key stations located in different climatic zones of Ethiopia over the common period 1965-2002. The progressive Mann-Kendall trend test shows that there is no trend in the annual rainfall total, the seasonal rainfall total or rainy days over central, northern and northwestern Ethiopia in the period 1965-2002. In contrast, the annual and the June-September total rainfalls for the eastern (Jijiga, 137 mm/decade), southern (Negele, 119 mm/decade) and southwestern (Gore 257 mm/decade) stations show a significant decline since about 1982. Correlation analysis shows that the decline of rainfall in eastern, south and southwestern Ethiopia is caused by the corresponding persistent warming of the South Atlantic Ocean over the period approximately from 1986 to 2002. The sea-surface temperature (SST) over the tropical eastern Pacific Ocean is not significantly correlated with the main rainfall of the semi-arid lowland areas of eastern, southern, and southwestern Ethiopia, except at marginal zones in transition to the Ethiopian Highlands.June-September rainfall over the Ethiopian Highlands is positively correlated to the equatorial east Pacific sea-level pressure and the southern oscillation index, and negatively correlated to SST over the tropical eastern Pacific Ocean as expected, confirming again that warm El Niño-southern oscillation episodes are associated with below-average June-September rainfall over the Ethiopian Highlands.

    With the rising prevalence of antimicrobial resistance, the failure rate of the standard triple therapy for Helicobacter pylori infection is increasing. Sequential therapy and concomitant therapy have been recommended to replace standard triple therapy for H. pylori eradication in regions with high clarithromycin resistance. The aim of this prospective, randomized, and controlled study was to simultaneously assess the efficacies of 10-day sequential and 7-day concomitant therapies versus a 7-day standard triple therapy for treating H. pylori infection. Consecutive H. pylori-infected subjects were randomly assigned to a 7-day standard triple therapy (pantoprazole, clarithromycin, and amoxicillin for 7 days), a 10-day sequential therapy (pantoprazole and amoxicillin for 5 days, followed by pantoprazole, clarithromycin, and metronidazole for a further 5 days), or a 7-day quadruple therapy (pantoprazole, clarithromycin, amoxicillin, and metronidazole for 7 days). H. pylori status was confirmed 6 weeks after therapy. Three hundred seven H. pylori-infected participants were randomized to receive triple (n = 103), sequential (n = 102), or concomitant (n = 102) therapies. The eradication rates by an intention-to-treat analysis in the three treatment groups were 81.6% (95% confidence interval [CI], 74.1% to 89.0%), 89.2% (95% CI, 83.2% to 95.2%), and 94.1% (95% CI, 89.5% to 98.7%). The seven-day concomitant therapy had a higher eradication rate than did the 7-day triple therapy (difference, 12.5%; 95% CI, 3.7% to 21.3%). There were no significant differences in the eradication rates between the sequential and standard triple therapies. All three treatments exhibited similar frequencies of adverse events (8.7%, 8.8%, and 13.7%, respectively) and drug compliance (99.0%, 98.0%, and 100.0%, respectively). In conclusion, the seven-day concomitant therapy is superior to the 7-day standard triple therapy for H. pylori eradication. Additionally, it is less complex than the 10-day sequential therapy because the drugs are not changed halfway through the treatment course.

  14. Day to day variability in fat oxidation and the effect after only 1 day of change in diet composition.

    Indirect calorimetry is a common and noninvasive method to estimate rate of fat oxidation (FatOx) during exercise, and test-retest reliability should be considered when interpreting results. Diet also has an impact on FatOx. The aim of the present study was to investigate day to day variations in FatOx during moderate exercise given the same diet and 2 different isoenergetic diets. Nine healthy, moderately-trained females participated in the study. They performed 1 maximal oxygen uptake test and 4 FatOx tests. Habitual diets were recorded and repeated to assess day to day variability in FatOx. FatOx was also measured after 1 day of fat-rich (26.8% carbohydrates (CHO), 23.2% protein, 47.1% fat) and 1 day of CHO-rich diet (62.6% CHO, 20.1% protein, 12.4% fat). The reliability test revealed no differences in FatOx, respiratory exchange ratio (RER), oxygen uptake, carbon dioxide production, heart rate, blood lactate concentration, or blood glucose between the 2 habitual diet days. FatOx decreased after the CHO-rich diet compared with the habitual day 2 (from 0.42 ± 0.15 to 0.29 ± 0.13 g·min(-1), p < 0.05). No difference was found in FatOx between fat-rich diet and the 2 habitual diet days. FatOx was 31% lower (from 0.42 ± 0.14 to 0.29 ± 0.13 g·min(-1), p < 0.01) after the CHO-rich diet compared with the fat-rich diet. Using RER data to measure FatOx is a reliable method as long as the diet is strictly controlled. However, even a 1-day change in macronutrient composition will likely affect the FatOx results.

  15. Twenty-Seven-Day Variation of Galactic Cosmic Rays

    NASA Astrophysics Data System (ADS)

    2007-09-01

    Neutron monitor data observed at Climax (CL) and Huancayo/Haleakala (HU/HAL) have been used to calculate the amplitude A of the 27-day variation of galactic cosmic rays (CRs). The median primary rigidity of response, R m, for these detectors encompasses the range 18 ≤ R m≤46 GV and the threshold rigidity R 0 covers the range 2.97≤ R 0≤12.9 GV. The daily average values of CR counts have been harmonically analyzed for each Bartels solar rotation (SR) during the period 1953 2001. The amplitude of the 27-day CR variation is cross-correlated to solar activity as measured by the sunspot number R, the interplanetary magnetic field (IMF) strength B, the z-component B z of the IMF vector, and the tilt angle ψ of the heliospheric current sheet (HCS). It is anticorrelated to the solar coronal hole area (CHA) index as well as to the solar wind speed V. The wind speed V leads the amplitude by 24 SRs. The amplitude of the 27-day CR variation is better correlated to each of the these parameters during positive solar polarity ( A>0) than during negative solar polarity ( A<0) periods. The CR modulation differs during A>0 from that during A<0 owing to the contribution of the z-component of the IMF. It differs during A 1>0 (1971 1980) from that during A 2>0 (1992 2001) owing to solar wind speed.

    Neither iterative registration, using drainage intersection maps for control, nor cross correlation techniques were satisfactory in registering day and night HCMM imagery. A procedure was developed which registers the image pairs by selecting control points and mapping the night thermal image to the daytime thermal and reflectance images using an affine transformation on a 1300 by 1100 pixel image. The resulting image registration is accurate to better than two pixels (RMS) and does not exhibit the significant misregistration that was noted in the temperature-difference and thermal-inertia products supplied by NASA. The affine transformation was determined using simple matrix arithmetic, a step that can be performed rapidly on a minicomputer.

  14. Quantum correlations from classically correlated states

    Consider a bipartite quantum system with at least one of its two components being itself a composite system. By tracing over part of one (or both) of these two subsystems it is possible to obtain a reduced (separable) state that exhibits quantum correlations even if the original state of the full system is endowed only with classical correlations. This effect, first pointed out by Li and Luo in (2008), is of considerable interest because there is a growing body of evidence suggesting that quantum correlations in non-entangled, mixed states may constitute a useful resource to implement non trivial information related tasks. Here we conduct a systematic exploration of the aforementioned effect for particular families of states of quantum systems of low dimensionality (three qubits states). In order to assess the non-classicality of the correlations of the reduced states we use an indicator of quantum correlations based upon the state disturbances generated by the measurement of local observables. We show, for a three-qubit system, that there exists a relationship between the classical mutual information of the original classically correlated states and the maximum quantum correlation exhibited by the reduced states.

    We report here on the software Hack Day organised at the 2014 SPIE conference on Astronomical Telescopes and Instrumentation in Montréal. The first ever Hack Day to take place at an SPIE event, the aim of the day was to bring together developers to collaborate on innovative solutions to problems of their choice. Such events have proliferated in the technology community, providing opportunities to showcase, share and learn skills. In academic environments, these events are often also instrumental in building community beyond the limits of national borders, institutions and projects. We show examples of projects the participants worked on, and provide some lessons learned for future events.

  16. Responses of the lower thermospheric temperature to the 9 day and 13.5 day oscillations of recurrent geomagnetic activity

    Responses of the lower thermospheric temperature to the 9 day and 13.5 day oscillations of recurrent geomagnetic activity and solar EUV radiation have been investigated using neutral temperature data observed by the TIMED/SABER (Thermosphere IonosphereMesosphere Energetics and Dynamics/Sounding of the Atmosphere using Broadband Emission Radiometry) instrument and numerical experiments by the NCAR-TIME-GCM (National Center for Atmospheric Research-thermosphere-ionosphere-mesosphere electrodynamics-general circulation model). The TIMED/SABER data analyzed were for the period from 2002 to 2007 during the declining phase of solar cycle 23. The observations show that the zonal mean temperature in the lower thermosphere oscillated with periods of near 9 and 13.5 days in the height range of 100-120 km. These oscillations were more strongly correlated with the recurrent geomagnetic activity than with the solar EUV variability of the same periods. The 9 day and 13.5 day oscillations of lower thermospheric temperature had greater amplitudes at high latitudes than at low latitudes; they also had larger amplitudes at higher altitudes, and the oscillations could penetrate down to ~105 km, depending on the strength of the recurrent geomagnetic activity for a particular time period. The data further show that the periodic responses of the lower thermospheric temperature to recurrent geomagnetic activity were different in the two hemispheres. In addition, numerical experiments have been carried out using the NCAR-TIME-GCM to investigate the causal relationship between the temperature oscillations and the geomagnetic activity and solar EUV variations of the same periods. Model simulations showed the same periodic oscillations as those seen in the observations when the real geomagnetic activity index, Kp, was used to drive the model. These numerical results show that recurrent geomagnetic activity is the main cause of the 9 day and 13.5 day variations in the lower thermosphere temperature, and the contribution from solar EUV variations is minor. Furthermore, we also found that consecutive coronal mass ejection events could cause long-duration enhancements in the lower thermospheric temperature that strengthen the 9 day and 13.5 day signals, and this kind of phenomenon mostly occurred between 2002 and 2005 during the declining phase of solar cycle 23.

    We couple airborne, ground-based, and satellite observations; conduct regional simulations; and develop and apply an inversion technique to constrain hourly smoke emissions from the Rim Fire, the third largest observed in California, USA. Emissions constrained with multiplatform data show notable nocturnal enhancements (sometimes over a factor of 20), correlate better with daily burned area data, and are a factor of 2–4 higher than a priori estimates, highlighting the need for improved characterization of diurnal profiles and day-to-day variability when modeling extreme fires. Constraining only with satellite data results in smaller enhancements mainly due to missing retrievals near the emissions source, suggesting that top-down emission estimates for these events could be underestimated and a multiplatform approach is required to resolve them. Predictions driven by emissions constrained with multiplatform data present significant variations in downwind air quality and in aerosol feedback on meteorology, emphasizing the need for improved emissions estimates during exceptional events.

  13. Lagged correlation networks

    NASA Astrophysics Data System (ADS)

    Curme, Chester

    Technological advances have provided scientists with large high-dimensional datasets that describe the behaviors of complex systems: from the statistics of energy levels in complex quantum systems, to the time-dependent transcription of genes, to price fluctuations among assets in a financial market. In this environment, where it may be difficult to infer the joint distribution of the data, network science has flourished as a way to gain insight into the structure and organization of such systems by focusing on pairwise interactions. This work focuses on a particular setting, in which a system is described by multivariate time series data. We consider time-lagged correlations among elements in this system, in such a way that the measured interactions among elements are asymmetric. Finally, we allow these interactions to be characteristically weak, so that statistical uncertainties may be important to consider when inferring the structure of the system. We introduce a methodology for constructing statistically validated networks to describe such a system, extend the methodology to accommodate interactions with a periodic component, and show how consideration of bipartite community structures in these networks can aid in the construction of robust statistical models. An example of such a system is a financial market, in which high frequency returns data may be used to describe contagion, or the spreading of shocks in price among assets. These data provide the experimental testing ground for our methodology. We study NYSE data from both the present day and one decade ago, examine the time scales over which the validated lagged correlation networks exist, and relate differences in the topological properties of the networks to an increasing economic efficiency. We uncover daily periodicities in the validated interactions, and relate our findings to explanations of the Epps Effect, an empirical phenomenon of financial time series. We also study bipartite community structures in networks composed of market returns and news sentiment signals for 40 countries. We compare the degrees to which markets anticipate news, and news anticipate markets, and use the community structures to construct a recommender system for inputs to prediction models. Finally, we complement this work with novel investigations of the exogenous news items that may drive the financial system using topic models. This includes an analysis of how investors and the general public may interact with these news items using Internet search data, and how the diversity of stories in the news both responds to and influences market movements.

  14. Clinical correlates with diaper dermatitis.

    PubMed

    Benjamin, L

    1987-01-01

    Three types of clinical studies were carried out to better understand diaper dermatitis in a general infant population. In 'snapshot' clinical studies, skin condition under the diaper was evaluated at a given point in time across a large base of infants. Correlations were sought between diaper dermatitis incidence and severity and a number of factors, including sex, diet, maturity, type of diaper, history of allergy, contact with fecal matter, presence of Candida albicans, and diaper change frequency. Severe diaper rash correlated strongly with the presence of C. albicans, and the frequency of rash correlated with duration of contact with feces and inversely with diaper change frequency. Diaper rash peaked at ages 9-12 months and was lower for breast-fed than for formula-fed infants. Exclusive use of disposable diapers correlated with lower rash levels than when some or all cloth diapers were used. In a longitudinal study, infants were observed daily for 50 days in order to determine the frequency and duration of rash episodes. In this study, the tendency for some infants to be rash-prone was clearly indicated. In a third type of study, over 10,000 infant visits to physicians' offices were used to record skin condition. Results showed a three-to fourfold increase in diaper rash if the child had diarrhea during the previous 48 h. PMID:3299331

    The 365 Days of Astronomy Podcast is a community project that brings the voices of the global astronomy community to the public over the Internet. We are publishing 1 podcast per day, 5 to 10 minutes in duration, for all 365 days of 2009. The podcast is made available through an RSS feed. The podcast episodes are recorded and listened to by people around the world. Topics covered include astronomy inspired art and literature, historic discoveries, spacecraft, IYA events as well as interviews and discussions about the science of astronomy. Some podcasts have a specific topic or theme based on The 365 Days of Astronomy Calendar, a daily calendar of astronomical events, themes and ideas created by the IYA. Although all the episodes will have a common intro and outtro that ties into the overall theme, each episode is completely different. Are you willing to contribute to the 365 Days of Astronomy podcast?We are looking for individuals, schools, companies and clubs to provide 5 - 10 minutes of audio for our daily podcast. Our goal is to encourage people to sign up for a particular day (or days) of 2009. We have a calendar of astronomical events to give ideas but the podcasts can be about virtually any astronomical topic. We are seeking a wide range of contributions, from simple concepts or how-tos to more in-depth discussions of complex concepts. We are expecting a wide range of contributions, from simple at-home "first light” podcasts to highly polished and professional recordings. We hope to sign up a wide range of participants including professional astronomers, K-12 classrooms, college students, science bloggers, podcasters and media companies.

  18. Good days, bad days: wind as a driver of foraging success in a flightless seabird, the southern rockhopper penguin.

    PubMed

    Dehnhard, Nina; Ludynia, Katrin; Poisbleau, Maud; Demongin, Laurent; Quillfeldt, Petra

    2013-01-01

    Due to their restricted foraging range, flightless seabirds are ideal models to study the short-term variability in foraging success in response to environmentally driven food availability. Wind can be a driver of upwelling and food abundance in marine ecosystems such as the Southern Ocean, where wind regime changes due to global warming may have important ecological consequences. Southern rockhopper penguins (Eudyptes chrysocome) have undergone a dramatic population decline in the past decades, potentially due to changing environmental conditions. We used a weighbridge system to record daily foraging mass gain (the difference in mean mass of adults leaving the colony in the morning and returning to the colony in the evening) of adult penguins during the chick rearing in two breeding seasons. We related the day-to-day variability in foraging mass gain to ocean wind conditions (wind direction and wind speed) and tested for a relationship between wind speed and sea surface temperature anomaly (SSTA). Foraging mass gain was highly variable among days, but did not differ between breeding seasons, chick rearing stages (guard and crèche) and sexes. It was strongly correlated between males and females, indicating synchronous changes among days. There was a significant interaction of wind direction and wind speed on daily foraging mass gain. Foraging mass gain was highest under moderate to strong winds from westerly directions and under weak winds from easterly directions, while decreasing under stronger easterly winds and storm conditions. Ocean wind speed showed a negative correlation with daily SSTA, suggesting that winds particularly from westerly directions might enhance upwelling and consequently the prey availability in the penguins' foraging areas. Our data emphasize the importance of small-scale, wind-induced patterns in prey availability on foraging success, a widely neglected aspect in seabird foraging studies, which might become more important with increasing changes in climatic variability.

    Due to their restricted foraging range, flightless seabirds are ideal models to study the short-term variability in foraging success in response to environmentally driven food availability. Wind can be a driver of upwelling and food abundance in marine ecosystems such as the Southern Ocean, where wind regime changes due to global warming may have important ecological consequences. Southern rockhopper penguins (Eudyptes chrysocome) have undergone a dramatic population decline in the past decades, potentially due to changing environmental conditions. We used a weighbridge system to record daily foraging mass gain (the difference in mean mass of adults leaving the colony in the morning and returning to the colony in the evening) of adult penguins during the chick rearing in two breeding seasons. We related the day-to-day variability in foraging mass gain to ocean wind conditions (wind direction and wind speed) and tested for a relationship between wind speed and sea surface temperature anomaly (SSTA). Foraging mass gain was highly variable among days, but did not differ between breeding seasons, chick rearing stages (guard and crèche) and sexes. It was strongly correlated between males and females, indicating synchronous changes among days. There was a significant interaction of wind direction and wind speed on daily foraging mass gain. Foraging mass gain was highest under moderate to strong winds from westerly directions and under weak winds from easterly directions, while decreasing under stronger easterly winds and storm conditions. Ocean wind speed showed a negative correlation with daily SSTA, suggesting that winds particularly from westerly directions might enhance upwelling and consequently the prey availability in the penguins' foraging areas. Our data emphasize the importance of small-scale, wind-induced patterns in prey availability on foraging success, a widely neglected aspect in seabird foraging studies, which might become more important with increasing changes in climatic variability.

  2. Optomechanical Quantum Correlation Thermometry

    NASA Astrophysics Data System (ADS)

    Purdy, T. P.; Grutter, K. E.; Davanco, M. I.; Srinivasan, K.; Taylor, J. M.

    We present an optomechanical approach for producing accurate thermometry over a wide temperature range using quantum Brownian motion. Optical measurements induce quantum correlations in an optomechanical system when quantum-limited intensity fluctuations of a probe laser drive mechanical motion. The size of the correlations in the weak probe limit are dictated by the scale of individual phonons. We have recently measured optomechanical quantum correlations in the cross correlation spectrum between the amplitude and phase fluctuations of a single probe laser interacting with a silicon nitride optomechanical crystal. These correlations are independent of thermally-induced Brownian motion. However, Brownian motion does simultaneously produce much larger correlation signals between other optical quadratures. A comparison of the size of thermally-induced correlations to quantum correlations allows us to absolutely calibrate Brownian motion thermometry to the mechanical energy quantization scale.

    The relationships between pilot fatigue, pilot deviations, reported incidents, and time of day are examined. A sample of 200 Aviation Safety Reporting System (ASRS) reports were analyzed from 1985 and 200 reports from 1987, plus 100 reports from late 1987 and early 1988 that were selected because of possible association with fatigue. The FAA pilot deviation data and incident data were analyzed in relation to denominator data that summarized the hourly operations (landings and takeoffs of scheduled flights) at major U.S. airports. Using as numerators FAA data on pilot deviations and incidents reported to the FAA, the rates by time of day were calculated. Pilot age was also analyzed in relation to the time of day, phase of flight, and type of incident.

  3. Dynamics of electricity market correlations

    NASA Astrophysics Data System (ADS)

    Alvarez-Ramirez, J.; Escarela-Perez, R.; Espinosa-Perez, G.; Urrea, R.

    2009-06-01

    Electricity market participants rely on demand and price forecasts to decide their bidding strategies, allocate assets, negotiate bilateral contracts, hedge risks, and plan facility investments. However, forecasting is hampered by the non-linear and stochastic nature of price time series. Diverse modeling strategies, from neural networks to traditional transfer functions, have been explored. These approaches are based on the assumption that price series contain correlations that can be exploited for model-based prediction purposes. While many works have been devoted to the demand and price modeling, a limited number of reports on the nature and dynamics of electricity market correlations are available. This paper uses detrended fluctuation analysis to study correlations in the demand and price time series and takes the Australian market as a case study. The results show the existence of correlations in both demand and prices over three orders of magnitude in time ranging from hours to months. However, the Hurst exponent is not constant over time, and its time evolution was computed over a subsample moving window of 250 observations. The computations, also made for two Canadian markets, show that the correlations present important fluctuations over a seasonal one-year cycle. Interestingly, non-linearities (measured in terms of a multifractality index) and reduced price predictability are found for the June-July periods, while the converse behavior is displayed during the December-January period. In terms of forecasting models, our results suggest that non-linear recursive models should be considered for accurate day-ahead price estimation. On the other hand, linear models seem to suffice for demand forecasting purposes.

  4. Measurements of Newton's gravitational constant and the length of day

    NASA Astrophysics Data System (ADS)

    Anderson, J. D.; Schubert, G.; Trimble, V.; Feldman, M. R.

    2015-04-01

    About a dozen measurements of Newton's gravitational constant, G, since 1962 have yielded values that differ by far more than their reported random plus systematic errors. We find that these values for G are oscillatory in nature, with a period of P = 5.899 +/- 0.062 \\text{yr} , an amplitude of (1.619 +/- 0.103) × 10-14 \\text{m}3 \\text{kg}-1 \\text{s}-2 , and mean-value crossings in 1994 and 1997. However, we do not suggest that G is actually varying by this much, this quickly, but instead that something in the measurement process varies. Of other recently reported results, to the best of our knowledge, the only measurement with the same period and phase is the Length of Day (LOD —defined as a frequency measurement such that a positive increase in LOD values means slower Earth rotation rates and therefore longer days). The aforementioned period is also about half of a solar activity cycle, but the correlation is far less convincing. The 5.9 year periodic signal in LOD has previously been interpreted as due to fluid core motions and inner-core coupling. We report the G/LOD correlation, whose statistical significance is 0.99764 assuming no difference in phase, without claiming to have any satisfactory explanation for it. Least unlikely, perhaps, are currents in the Earth's fluid core that change both its moment of inertia (affecting LOD) and the circumstances in which the Earth-based experiments measure G. In this case, there might be correlations with terrestrial-magnetic-field measurements.

  5. Time-of-day variation of visuo-spatial attention.

    Fimm, Bruno; Brand, Tanja; Spijkers, Will

    2016-05-01

    Time-of-day variation of visuo-spatial attention in relation to body temperature and subjective arousal was assessed. At five different times of day, alertness, covert, and overt orienting of attention were assessed in fifteen healthy subjects. Based on previous studies reporting a tight coupling of alerting and orienting the present study investigates potential attentional asymmetries induced by diurnal variations of arousal. Both covert and overt orienting of attention improved in the course of the day. However, no asymmetries between left and right visual hemifields could be detected. Covert orienting additionally covaried with body temperature, indicating a quite close relation between the attentional arousal and orienting system. Conversely, overt orienting only improved due to repeated testing but did not correlate with body temperature suggesting a partial independence of both modes of attentional orienting. It can be assumed that due to limited diurnal variations of arousal in the participants and practice effects caused by repeated testing, no attentional asymmetries could be provoked. PMID:26248950

    Urinary drug metabolites were measured in 21 patients receiving ifosfamide by continuous infusion over 3 days. Mean values for the proportion of drug excreted as parent compound, 2-dechloroethylifosfamide (2-DC), 3-dechloroethylifosfamide (3-DC), carboxyifosfamide (CX) and ifosforamide mustard (IPM) were 19, 6, 10, 7 and 8% of dose respectively. The proportion of urinary drug products in the form of ifosfamide fell considerably over the course of the 3 days. This was mirrored by an increase in the proportion of 2-DC, 3-DC and CX. The proportion in the form of IPM, however, remained unchanged. With successive cycles the amount of 2-DC and IPM increased by about 10% per course. A very wide variation in the amount of each metabolite was reproducibly seen between patients, but no evidence for a genetic polymorphism was found. Urinary dechloroethyl metabolites correlated positively with each other and negatively with CX. Although autoinduction increases 'activation' of ifosfamide when given over 3 days, our evidence suggests that competing metabolic pathways prevent an increase in the amount of active metabolite formed.

    In a previous paper, Fraser and Thorpe (1976) indicated that the average partial-coherence spectra for three summers and the average for three winters at a southern mid-latitude site had a dominant peak at a period of about six days. This peak in coherence between absorption and temperature is anomalous, and the present paper explains how some of the unexpected coherence features can be explained by the five-day wave described by Geisler and Dickinson (1976) and whose existence in the upper stratosphere was discussed by Rodgers (1976).

    To prevent high rates of nurse burnout and staff turnover, hospitals must create environments that fulfil nurses' expectations and foster positive emotional responses to their job. To gain an understanding of what triggers positive emotional responses, a group of nurses were asked to recall an 'extraordinary day'. Their descriptions were analysed to identify these triggers and to determine whether their perceptions of what makes an extraordinary day change over time. This article discusses the results of the study and suggests that enabling nurses to describe meaningful experiences is a step toward learning what it is they value. PMID:23705544

This is achieved by describing in brief the timeline of discoveries relevant to clinical neurology and the investigation of neurological diseases. This provides a background understanding for the limitations inherent in the early days when investigations and imaging in particular were fairly primitive. It also helps to explain the choices that were made by the pioneers in those early days. The limitations of operative procedures and institutions designed to treat neurological diseases are also mentioned. PMID:25376564

  12. High-resolution correlation

    NASA Astrophysics Data System (ADS)

    Nelson, D. J.

    2007-09-01

    In the basic correlation process a sequence of time-lag-indexed correlation coefficients are computed as the inner or dot product of segments of two signals. The time-lag(s) for which the magnitude of the correlation coefficient sequence is maximized is the estimated relative time delay of the two signals. For discrete sampled signals, the delay estimated in this manner is quantized with the same relative accuracy as the clock used in sampling the signals. In addition, the correlation coefficients are real if the input signals are real. There have been many methods proposed to estimate signal delay to more accuracy than the sample interval of the digitizer clock, with some success. These methods include interpolation of the correlation coefficients, estimation of the signal delay from the group delay function, and beam forming techniques, such as the MUSIC algorithm. For spectral estimation, techniques based on phase differentiation have been popular, but these techniques have apparently not been applied to the correlation problem . We propose a phase based delay estimation method (PBDEM) based on the phase of the correlation function that provides a significant improvement of the accuracy of time delay estimation. In the process, the standard correlation function is first calculated. A time lag error function is then calculated from the correlation phase and is used to interpolate the correlation function. The signal delay is shown to be accurately estimated as the zero crossing of the correlation phase near the index of the peak correlation magnitude. This process is nearly as fast as the conventional correlation function on which it is based. For real valued signals, a simple modification is provided, which results in the same correlation accuracy as is obtained for complex valued signals.

    Prevention and control of diarrhea in day care settings depends on: maintenance of hygienic standards; disease surveillance; adhering to a policy for exclusion of children with diarrhea; and education of staff. When diarrhea afflicts several children, isolating together can stop the spread of disease without interrupting normal operation. (KH)

    1986-01-01

    In July 1983, the Thermal Infrared Multispectral Scanner (TIMS) was flown over Death Valley, California on both a midday and predawn flight within a two-day period. The availability of calibrated digital data permitted the calculation of day and night surface temperature and surface spectral emittance. Image processing of the data included panorama correction and calibration to radiance using the on-board black bodies and the measured spectral response of each channel. Scene-dependent isolated-point noise due to bit drops, was located by its relatively discontinuous values and replaced by the average of the surrounding data values. A method was developed in order to separate the spectral and temperature information contained in the TIMS data. Night and day data sets were processed. The TIMS is unique in allowing collection of both spectral emittance and thermal information in digital format with the same airborne scanner. For the first time it was possible to produce day and night emittance images of the same area, coregistered. These data add to an understanding of the physical basis for the discrimination of difference in surface materials afforded by TIMS.
