Practice in mind: Help to improve golf putting from the Hardest Distance

Psychological Skills Training (PST) particularly imagery is a strategy that can improve the performance of golfers. Additionally, golfers had a problem when putting from a 6-feet distance compared to other distances (3, 12, and 24 feet). The objective of this study was to investigate the effectiveness of PETTLEP imagery on putting performance of the golfers from the 6-feet distance. Forty-two male golfers aged 18 to 25 years with 1 to 3 year playing experiences participated in this study. After screening of imagery ability, all participants were randomly assigned into two different groups (i.e., PETTLEP imagery group and physical practice only (control group). All participants in PETTLEP imagery completed 10 imagery practices together with 10 physical practices. Meanwhile, the control group only performed 10 putting strokes and read a guideline on stretching to improve flexibility in a 6- week programme. Pre and post putting test was conducted from a 6-feet distance. An independent sample t-test results revealed that PETTLEP imagery group improved on putting scores compared to the control group. The finding supports the idea of using PETTLEP imagery to improve golf performance. Research still needs to be conducted particularly in the mediating role of self-efficacy of PETTLEP imagery in golf putting from the 6-feet distance.
The Impact of Phase Fading on the Dirty Paper Channel

The impact of phase fading on the classical Costa dirty paper coding channel is studied. We consider a variation of this channel model in which the amplitude of the interference sequence is known at the transmitter while its phase is known at the receiver. Although the capacity of this channel has already been established, it is expressed using an auxiliary random variable and as the solution of a maximization problem. To circumvent the difficulty evaluating capacity, we derive alternative inner and outer bounds and show that the two expressions are to within a finite distance. This provide an approximate characterization of the capacity which depends only on the channel parameters. We consider, in particular, two distributions of the phase fading: circular binomial and circular uniform. The first distribution models the scenario in which the transmitter has a minimal uncertainty over the phase of the interference while the second distribution models complete uncertainty. For circular binomial fading, we show that binning with Gaussian signaling still approaches capacity, as in the channel without phase fading. In the case of circular uniform fading, instead, binning with Gaussian signaling is no longer effective and novel interference avoidance strategies are developed to approach capacity.
A RELATIONSHIP BETWEEN SUPERMASSIVE BLACK HOLE MASS AND THE TOTAL GRAVITATIONAL MASS OF THE HOST GALAXY

We investigate the correlation between the mass of a central supermassive black hole (SMBH) and the total gravitational mass of the host galaxy (Mtot). The results are based on 43 galaxy-scale strong gravitational lenses from the Sloan Lens ACS Surveys (SLACS) Survey whose black hole masses were estimated through two scaling relations: the relation between black hole mass and Sérsic index (Mbh–n) and the relation between black hole mass and stellar velocity dispersion (Mbh–σ⋆). We use the enclosed mass within R200, the radius within which the density profile of the early type galaxy exceeds the critical density of the universe by a factor of 200, determined by gravitational lens models fitted to Hubble Space Telescope imaging data, as a tracer of the total gravitational mass. The best-fit correlation, where Mbh is determined from Mbh–σ⋆ relation, is log(Mbh) = (8.18 ± 0.11) + (1.55 ± 0.31)(log(Mtot)–13.0) over 2 orders of magnitude in Mbh. From a variety of tests, we find that we cannot reliably infer a connection between Mbh and Mtot from the Mbh–n relation. The Mbh–Mtot relation provides some of the first, direct observational evidence to test the prediction that SMBH properties are determined by the halo properties of the host galaxy.
Clinical phenotype of cystic fibrosis patients with the G551D mutation.

BACKGROUND Data on whether the phenotype of cystic fibrosis (CF) patients with compound heterozygocity for G551D (Gly551Asp) differs from patients with F508del (Phe508del) homozygous mutations is divergent. AIM We hypothesized that CF patients with the G551D mutation would have less severe disease than F508del homozygotes. DESIGN We compared the clinical phenotype of adult patients with a G551D mutation with adult patients homozygous for F508del and those with the missense mutation R117H (Arg117His). Compound heterozygotes for the G551D and R117H were analysed separately. METHODS Data were collected for 101 adult CF patients. Group 1-4 represents in order F508del homozygote patients (n = 61), those with the G551D mutation and a more severe mutation (n = 13), those with R117H mutation and a more severe mutation (n = 23) and also those compound for both the R117H and G551D mutations (n = 4). RESULTS Our findings have shown that adult patients with the G551D mutation and a second severe mutation have a milder clinical phenotype than F508del homozygous adult patients. Higher FEV(1) and body mass index and less impaired glucose tolerance was demonstrated in the patients with G551D and R117H compared to F508del homozygotes. There was a reduced yearly rate of decline of FEV(1) (P < 0.05), infection with Pseudomonas aeruginosa along with reduced burden of care. Compound heterozygosity for G551D and R117H mutations was associated with normal spirometry, body mass index, no chronic infection and no symptoms. CONCLUSION Mutations on different chromosomes are not independent of each other for the overall impact on the amount of functional CFTR. This study suggests that patients with the G551D mutation and a second severe mutation have a milder clinical phenotype than F508del homozygous patients, but the phenotype is not as mild as patients with the R117H mutation.
Expression of Ki-67 (MIB-1) and GLUT-1 proteins in non-advanced prostatic cancer.

The expression of Ki-67 (MIB-1) and glucose transporter-1 (GLUT-1) were evaluated in patients with clinically localized prostate cancer (PC) who had undergone radical prostatectomy with curative intent. 140 low advanced PC specimens were studied. Protein expression was assessed immunohistochemically on tumour sections and expressed as a labelling index, i.e. the percentage of positively stained cells. In the case of Ki-67 nuclear staining and in the case of GLUT-1 membrane and cytoplasmic staining was considered as positive. The patients' mean age was 62.9 ±6.2 years. There were 13 (9.3%) at pTNM stage 1, 78 (55.7%) at stage 2, 40 (28.6%) at stage 3 and 9 (6.4%) at stage 4, respectively. 75 (53.6%) tumours were well differentiated (Gleason score ≤6), 52 (37.1%) moderately differentiated (Gleason score of 7) and 13 (9.3%) poorly differentiated (Gleason score 8-10). The mean pre-operative serum PSA was 9.9 ± SE 0.5 ng/ml, and the mean LI was equal to 8.1 ±0.6% and 29.7 ±2.0%, for MIB-1 and GLUT-1, respectively. Increase of pathological tumor volume and tumor grade was associated with statistically significant growth of PSA (p < 0.011) and MIB-1LI (p < 0.003), however, for GLUT-1 LI the relation was not significant. Ki-67 expression was correlated with PSA levels (p = 0.013) and GLUT-1 scores (p = 0.04). In PC, an increase in the proliferation rate (higher MIB-1LI) in higher pTNM stages and tumour grades may point to Ki-67 as a good marker of biological aggressiveness useful in selecting patients for more aggressive treatment. A correlation between proliferation and GLUT-1 score may be the evidence of active glycolytic metabolism in hypoxic regions.
Parallel AP Clustering and Re-ranking for Automatic Image-Text Alignment and Large-Scale Web Image Search

In this paper, an automatic image-text alignment algorithm is developed for achieving more accurate indexing and retrieval of large-scale web images. First, large-scale web pages are crawled, where the informative images and their most relevant auxiliary text blocks are extracted. Second, parallel image clustering is performed to partition large-scale informative web images into a large number of clusters. By grouping the visually-similar (near-duplicate) web images into the same cluster, our parallel image clustering algorithm can significantly reduce the huge uncertainty on the relatedness between the web images and their auxiliary text terms, which can provide a good starting point for supporting automatic image-text alignment. Finally, a relevance re-ranking algorithm is developed to identify the most relevant visual text terms for the visually-similar web images in the same cluster. Our experiments on large-scale web images have obtained very positive results.
The Correlation between the X-Ray Spectral Slope and the Fe Kα Line Energy in Radio-quiet Active Galactic Nuclei

A significant correlation between the Fe Kα line energy and the X-ray spectral slope has been discovered among radio-quiet active galactic nuclei. The ionization stage of the bulk of the Fe Kα-emitting material is not the same in all active galactic nuclei and is related to the shape of the X-ray continua. Active galactic nuclei with a steep X-ray spectrum tend to have a fluorescence Fe Kα line from highly ionized material. In the narrow-line Seyfert 1 galaxies with a steeper X-ray spectrum (ΓX ≳ 2.1), the Fe Kα line originates from highly ionized material. In the Seyfert 1 galaxies and quasars with a flatter X-ray spectrum (ΓX ≲ 2.1), the bulk of the Fe Kα emission arises from near-neutral or weakly ionized material. The correlation is an important observational characteristic related to the accretion process in radio-quiet active galactic nuclei and is driven by a fundamental physical parameter that is likely to be the accretion rate relative to the Eddington rate.

Affective Modulation of Cognitive Control is Determined by Performance-Contingency and Mediated by Ventromedial Prefrontal and Cingulate Cortex

Cognitive control requires a fine balance between stability, the protection of an on-going task-set, and flexibility, the ability to update a task-set in line with changing contingencies. It is thought that emotional processing modulates this balance, but results have been equivocal regarding the direction of this modulation. Here, we tested the hypothesis that a crucial determinant of this modulation is whether affective stimuli represent performance-contingent or task-irrelevant signals. Combining functional magnetic resonance imaging with a conflict task-switching paradigm, we contrasted the effects of presenting negative- and positive-valence pictures on the stability/flexibility trade-off in humans, depending on whether picture presentation was contingent on behavioral performance. Both the behavioral and neural expressions of cognitive control were modulated by stimulus valence and performance contingency: in the performance-contingent condition, cognitive flexibility was enhanced following positive pictures, whereas in the nonperformance-contingent condition, positive stimuli promoted cognitive stability. The imaging data showed that, as anticipated, the stability/flexibility trade-off per se was reflected in differential recruitment of dorsolateral frontoparietal and striatal regions. In contrast, the affective modulation of stability/flexibility shifts was mirrored, unexpectedly, by neural responses in ventromedial prefrontal and posterior cingulate cortices, core nodes of the “default mode” network. Our results demonstrate that the affective modulation of cognitive control depends on the performance contingency of the affect-inducing stimuli, and they document medial default mode regions to mediate the flexibility-promoting effects of performance-contingent positive affect, thus extending recent work that recasts these regions as serving a key role in on-task control processes.
Capacity of the Gaussian Relay Channel with Correlated Noises to Within a Constant Gap

This paper studies the relaying strategies and the approximate capacity of the classic three-node Gaussian relay channel, but where the noises at the relay and at the destination are correlated. It is shown that the capacity of such a relay channel can be achieved to within a constant gap of 1/2 log2 3 =0.7925 bits using a modified version of the noisy network coding strategy, where the quantization level at the relay is set in a correlation dependent way. As a corollary, this letter establishes that the conventional compress-and-forward scheme also achieves to within a constant gap to the capacity. In contrast, the decode-and-forward and the single-tap amplify-and-forward relaying strategies can have an infinite gap to capacity in the regime where the noises at the relay and at the destination are highly correlated, and the gain of the relay-to-destination link goes to infinity.
A Flexible Semiparametric Model for Time Series

We consider approximating a multivariate regression function by an affine combination of one-dimensional conditional component regression functions. The weight parameters involved in the approximation are estimated by least squares on the first-stage nonparametric kernel estimates. We establish asymptotic normality for the estimated weights and the regression function in two cases: the number of the covariates is finite, and the number of the covariates is diverging. As the observations are assumed to be stationary and near epoch dependent, the approach in this paper is applicable to estimation and forecasting issues in time series analysis. Furthermore, the methods and results are augmented by a simulation study and illustrated by application in the analysis of the Australian annual mean temperature anomaly series. We also apply our methods to high frequency volatility forecasting, where we obtain superior results to parametric methods.
Epidemiologie und Strafverfolgung sexueller Gewalt gegen Frauen in Deutschland

Dass sexuelle Gewaltviktimisierungen mit erheblichen Folgen fur die Betroffenen einhergehen, ist unumstritten. Zusatzlich besteht die Gefahr sekundarer Viktimisierungsfolgen, die unter anderem (in-)direkt aus einem Strafverfahren und dessen Ergebnis resultieren konnen. Studien des Kriminologischen Forschungsinstituts Niedersachsen zufolge hat sich die Verbreitung sexueller Gewalt gegen Frauen in Deutschland von 1992 bis 2011 nahezu halbiert. Allerdings wird lediglich rund jeder funfte Fall sexueller Gewalt den Strafverfolgungsbehorden bekannt. Bei den angezeigten Fallen handelt es sich wiederum um solche, die mit besonders schwerwiegenden Folgen einhergehen. Hellfelddaten aus der Polizeilichen Kriminalstatistik und der Strafverfolgungsstatistik deuten zum einen auf einen Anstieg angezeigter Falle sexueller Gewalt und zum anderen auf einen Ruckgang der Verurteilungswahrscheinlichkeit in demselben Zeitraum hin. Zudem treten der Strafverfolgungsstatistik zufolge im bundesweiten Vergleich der Verurteilungsquoten erhebliche regionale Unterschiede auf, die es zu erklaren gilt. Im vorliegenden Beitrag werden mogliche Ursachen fur diese Datenlage dargestellt sowie offene Fragen und Losungsansatze erortert.
Criterion-Related Validity of Sit-and-Reach Tests for Estimating Hamstring and Lumbar Extensibility: a Meta-Analysis.

The main purpose of the present meta-analysis was to examine the scientific literature on the criterion-related validity of sit-and-reach tests for estimating hamstring and lumbar extensibility. For this purpose relevant studies were searched from seven electronic databases dated up through December 2012. Primary outcomes of criterion-related validity were Pearson´s zero-order correlation coefficients (r) between sit-and-reach tests and hamstrings and/or lumbar extensibility criterion measures. Then, from the included studies, the Hunter- Schmidt´s psychometric meta-analysis approach was conducted to estimate population criterion- related validity of sit-and-reach tests. Firstly, the corrected correlation mean (rp), unaffected by statistical artefacts (i.e., sampling error and measurement error), was calculated separately for each sit-and-reach test. Subsequently, the three potential moderator variables (sex of participants, age of participants, and level of hamstring extensibility) were examined by a partially hierarchical analysis. Of the 34 studies included in the present meta-analysis, 99 correlations values across eight sit-and-reach tests and 51 across seven sit-and-reach tests were retrieved for hamstring and lumbar extensibility, respectively. The overall results showed that all sit-and-reach tests had a moderate mean criterion-related validity for estimating hamstring extensibility (rp = 0.46-0.67), but they had a low mean for estimating lumbar extensibility (rp = 0. 16-0.35). Generally, females, adults and participants with high levels of hamstring extensibility tended to have greater mean values of criterion-related validity for estimating hamstring extensibility. When the use of angular tests is limited such as in a school setting or in large scale studies, scientists and practitioners could use the sit-and-reach tests as a useful alternative for hamstring extensibility estimation, but not for estimating lumbar extensibility. Key PointsOverall sit-and-reach tests have a moderate mean criterion-related validity for estimating hamstring extensibility, but they have a low mean validity for estimating lumbar extensibility.Among all the sit-and-reach test protocols, the Classic sit-and-reach test seems to be the best option to estimate hamstring extensibility.End scores (e.g., the Classic sit-and-reach test) are a better indicator of hamstring extensibility than the modifications that incorporate fingers-to-box distance (e.g., the Modified sit-and-reach test). When angular tests such as straight leg raise or knee extension tests cannot be used, sit-and-reach tests seem to be a useful field test alternative to estimate hamstring extensibility, but not to estimate lumbar extensibility.
Molecular Dynamics Study on the Distributed Plasticity of Penta-Twinned Silver Nanowires

The distributed plasticity of pentatwinned silver nanowires has been revealed in recent computational and experimental studies. However, the molecular dynamics (MD) simulations have not considered the imperfections seen in experiments, such as irregular surface undulations, the high aspect ratio of nanowires, and the stiffness of loading devices. In this work, we report the effect of such inherent imperfections on the distributed plasticity of penta-twinned silver nanowires in MD simulations. We find that the distributed plasticity occurs for nanowires having undulations that are less than 5% of the nanowire diameter. The elastic stress field induced by a stacking fault promotes the nucleation of successive stacking fault decahedrons (SFDs) at long distance, making it hard for necking to occur. By comparing the tensile simulation using the steered molecular dynamics (SMD) method with the tensile simulation with periodic boundary condition (PBC), we show that a sufficiently long nanowire must be used in the constant strain rate simulations with PBC, because the plastic displacement burst caused by the SFD formation induces compressive stress, promoting the removal of other SFDs. Our finding can serve as a guidance for the molecular dynamics simulation of crystalline materials with large plastic deformation, and in the design of mechanically reliable devices based on silver nanowires.
Basal ganglia and cortical networks for sequential ordering and rhythm of complex movements

Voluntary actions require the concurrent engagement and coordinated control of complex temporal (e.g., rhythm) and ordinal motor processes. Using high-resolution functional magnetic resonance imaging (fMRI) and multi-voxel pattern analysis (MVPA), we sought to determine the degree to which these complex motor processes are dissociable in basal ganglia and cortical networks. We employed three different finger-tapping tasks that differed in the demand on the sequential temporal rhythm or sequential ordering of submovements. Our results demonstrate that sequential rhythm and sequential order tasks were partially dissociable based on activation differences. The sequential rhythm task activated a widespread network centered around the supplementary motor area (SMA) and basal-ganglia regions including the dorsomedial putamen and caudate nucleus, while the sequential order task preferentially activated a fronto-parietal network. There was also extensive overlap between sequential rhythm and sequential order tasks, with both tasks commonly activating bilateral premotor, supplementary motor, and superior/inferior parietal cortical regions, as well as regions of the caudate/putamen of the basal ganglia and the ventro-lateral thalamus. Importantly, within the cortical regions that were active for both complex movements, MVPA could accurately classify different patterns of activation for the sequential rhythm and sequential order tasks. In the basal ganglia, however, overlapping activation for the sequential rhythm and sequential order tasks, which was found in classic motor circuits of the putamen and ventro-lateral thalamus, could not be accurately differentiated by MVPA. Overall, our results highlight the convergent architecture of the motor system, where complex motor information that is spatially distributed in the cortex converges into a more compact representation in the basal ganglia.
An improved model for the Normalized LMS algorithm with Gaussian inputs and large number of coefficients

This work presents a new analytical model for the Normalized Least Mean Square (NLMS) algorithm for Gaussian signals and large number of coefficients. These characteristics are of special interest in applications such as echo canceling and active noise control. The new results are compared to previous models described in the literature, showing a better agreement with Monte Carlo simulations even for unit step-size (maximum convergence speed). The new results contribute to an ongoing discussion about the relative performances of the NLMS and LMS algorithms. The new model shows that both algorithms have similar performances for a large number of coefficients and properly chosen step-sizes.
