Self-talk in running athletes: an ecological momentary assessment approach

A lot of research has been performed on the use of self-talk and the influence of self-talk on performance in sport. In this research the influence of fatigue and skill level on the use of self-talk remains unclear. A limitation of the self-talk research is the time-lag between the use and assessment of self-talk. Therefore the purpose of this study was to investigate how progressive fatigue affects the use of different types of self-talk (instructional, motivational, positive, negative) in recreational and competitive runners, by using a new EMA method to assess self-talk. Convergent validity of the EMA method was explored by comparing the results of self-talk assessed by EMA with self-talk assessed by questionnaires. 42 running athletes performed a strenuous interval exercise, which involved eight two-minute intervals with rest periods in which EMA was used to acquire participants’ self-talk data. Results revealed that under high fatigue running athletes made more use of positive and motivational self-talk and less use of instructional self-talk than under low fatigue, whereas their use of negative self-talk did not change. The use of self-talk was not influenced by skill level, although a noticeable trend was shown leaning towards competitive runners making more use of instructional and negative self-talk than recreational runners. Convergent validity of EMA and the questionnaires shows that EMA provides different results for assessing self-talk than using questionnaires. This suggests that retrospective questionnaires are not accurate reflections of instantaneous self-talk of running athletes. Research on self-talk should focus on creating a sound standard for assessing self-talk to further investigate the usability of EMA for gathering information about self-talk in the future.
W4: Real-Time Surveillance of People and Their Activities

W/sup 4/ is a real time visual surveillance system for detecting and tracking multiple people and monitoring their activities in an outdoor environment. It operates on monocular gray-scale video imagery, or on video imagery from an infrared camera. W/sup 4/ employs a combination of shape analysis and tracking to locate people and their parts (head, hands, feet, torso) and to create models of people's appearance so that they can be tracked through interactions such as occlusions. It can determine whether a foreground region contains multiple people and can segment the region into its constituent people and track them. W/sup 4/ can also determine whether people are carrying objects, and can segment objects from their silhouettes, and construct appearance models for them so they can be identified in subsequent frames. W/sup 4/ can recognize events between people and objects, such as depositing an object, exchanging bags, or removing an object. It runs at 25 Hz for 320/spl times/240 resolution images on a 400 MHz dual-Pentium II PC.
Complete Mitochondrial Genome of Phytophthora nicotianae and Identification of Molecular Markers for the Oomycetes

Phytophthora nicotianae is one of the most destructive plant pathogens affecting a variety of plants, causing black shank of tobacco, among several other devastating diseases. Herein, we assembled the mitochondrial genome of P. nicotianae and analyzed its gene content and genome structure, performed comparative mitochondrial genomics analysis, and assessed phylogenetic relationships among oomycetes species. The circular mitogenome is 37,561 bp long, with 38 protein-coding genes, 25 transfer RNA (tRNA) genes, and 2 ribosomal RNA genes (rrnl and rrns). The mitochondrial genome showed a biased A/T usage versus G/C. The overall gene content and size of the P. nicotianae mitogenome are identical to those of other published Phytophthora mitogenomes. Interestingly, collinearity analysis using an existing ∼10 k inversion region (including 11 genes and 8 tRNAs) revealed that Phytophthora andina, Phytophthora infestans, Phytophthora mirabilis, Phytophthora ipomoeae, and Phytophthora phaseoli differed from Phytophthora nicotianae, Phytophthora sojae, Phytophthora ramorum, and Phytophthora polonica. Moreover, inverted repeat regions were found to be absent among species of the Peronosporales when compared with species from the Pythiales and Saprolegniales. A phylogenomic investigation based on 29 protein-coding genes demonstrated that Phytophthora is monophyletic, and placed P. nicotianae close to the clade including P. mirabilis, P. ipomoeae, P. andina, P. infestans, and P. phaseoli. Furthermore, we discovered six new candidate DNA molecular markers (rpl6, atp8, nad11, rps2, rps3, and rps4) based on these mitogenomes that would be suitable for species identification in the oomycetes, which have the same identification level as the whole mitogenome and ribosomal DNA sequences. These new molecular markers can not only provide a quick preview of the species without mitogenome information, but will also help to gain better understanding of the oomycetes pathogens and developing treatment or monitoring strategies.
RecD Plays an Essential Function During Growth at Low Temperature in the Antarctic Bacterium Pseudomonas syringae Lz4W

The Antarctic psychrotrophic bacterium Pseudomonas syringae Lz4W has been used as a model system to identify genes that are required for growth at low temperature. Transposon mutagenesis was carried out to isolate mutant(s) of the bacterium that are defective for growth at 4° but normal at 22°. In one such cold-sensitive mutant (CS1), the transposon-disrupted gene was identified to be a homolog of the recD gene of several bacteria. Trans-complementation and freshly targeted gene disruption studies reconfirmed that the inactivation of the recD gene leads to a cold-sensitive phenotype. We cloned, sequenced, and analyzed ∼11.2 kbp of DNA from recD and its flanking region from the bacterium. recD was the last gene of a putative recCBD operon. The RecD ORF was 694 amino acids long and 40% identical (52% similar) to the Escherichia coli protein, and it could complement the E. coli recD mutation. The recD gene of E. coli, however, could not complement the cold-sensitive phenotype of the CS1 mutant. Interestingly, the CS1 strain showed greater sensitivity toward the DNA-damaging agents, mitomycin C and UV. The inactivation of recD in P. syringae also led to cell death and accumulation of DNA fragments of ∼25–30 kbp in size at low temperature (4°). We propose that during growth at a very low temperature the Antarctic P. syringae is subjected to DNA damage, which requires direct participation of a unique RecD function. Additional results suggest that a truncated recD encoding the N-terminal segment of (1–576) amino acids is sufficient to support growth of P. syringae at low temperature.
Abnormal tear dynamics and symptoms of eyestrain in operators of visual display terminals.

OBJECTIVES: To clarify the relation between the prevalence of dry eye syndrome and subjective symptoms of asthenopia in visual display terminal (VDT) operators. METHOD: 722 VDT workers (242 subject workers with symptoms of asthenopia and 480 controls without such symptoms) without obvious organic ocular diseases received an ophthalmological examination consisting of refractometry and a tear function (phenol red thread) test. RESULTS: More than 30% of symptomatic workers were found to meet the criteria of dry eye, and the odds ratio compared with the controls was 4.61 (p < 0.001). This odds ratio was significantly greater than that obtained for refractive errors (2.31). CONCLUSIONS: Although this cross sectional study could not prove that dry eyes are the cause of asthenopia, the profound association of dry eyes with symptoms of asthenopia could be verified. It would be useful to carry out tear function tests in workers with symptoms of asthenopia.
Supercritical percolation on large scale-free random trees

We consider Bernoulli bond percolation on a large scale-free tree in the supercritical regime, meaning informally that there exists a giant cluster with high probability. We obtain a weak limit theorem for the sizes of the next largest clusters, extending a recent result in Bertoin [Random Structures Algorithms 44 (2014) 29-44] for large random recursive trees. The approach relies on the analysis of the asymptotic behavior of branching processes subject to rare neutral mutations, which may be of independent interest.
Bmc Complementary and Alternative Medicine Antioxidant Activities and Phenolic Contents of the Methanol Extracts of the Stems of Acokanthera Oppositifolia and Adenia Gummifera

Background: Acokanthera oppositifolia Lam (family: Apocynaceae) is a shrub or small tree with white latex, and the leaves of this plant are used in the form of a snuff to treat headaches and in infusions for abdominal pains and convulsions and septicaemia. Adenia gummifera Harv of the family Passifloraceae is a distinctive woody climber whose infusions are used as emetics and are said to help with some forms of depression. Lipid peroxidation has gained more importance today because of its involvement in pathogenesis of many diseases. Free radicals are the main agents in lipid peroxidation. Antioxidants thus play an important role of protecting the human body against damage by the free radicals. Plants containing phenolic compounds have been reported to possess strong antioxidant properties.
CMOS current-copying neural stimulator with OTA-sharing

We present a compact current mode stimulator for utilization in neural stimulation arrays. The stimulator is implemented in a 0. 35µm CMOS technology and occupies an area of 50µm×400µm. The memory in every current driver allows for simultaneous stimulation on multiple active channels when used as part of an array of stimulators. Circuit reuse in the stimulator and utilization of a single DAC yield a compact and low-power implementation. The current driver dissipates a quiescent power of 2. 76µW. The stimulator can output current in the range of 10µA–250µA.
Distributed Tree Rearrangements for Reachability and Robust Connectivity

We study maintenance of network connectivity in robotic swarms with discrete-time communications and continuous-time motion capabilities. Assuming a network topology induced by spatial proximity, we propose a coordination scheme which guarantees connectivity of the network by maintaining a spanning tree at all times. Our algorithm is capable of repairing the spanning tree in the event of link failure, and of transitioning from any initial tree to any other tree which is a subgraph of the communications graph.
Large grains in discs around young stars: ATCA observations of WW Chamaeleontis, RU Lupi and CS Chamaeleontis

Context. Grains in discs around young stars grow from interstellar submicron sizes to planetesimals, up to thousands of kilometres in size, over the course of several Myr. Thermal emission of large grains or pebbles can be best observed at centimetre wavelengths. However, other emission mechanisms can contribute, most notably free-free emission from stellar winds and chromospheric activity. Aims. We aim to determine the mechanisms of centimetre emission for three T Tauri stars. WW Cha and RU Lup have recently been found to have grain growth at least up to millimetre sizes in their circumstellar discs, based on millimetre data up to 3.3 mm. CS Cha has similar indications of grain growth in its circumbinary disc. Methods. The T Tauri stars WW Cha and RU Lup were monitored over the course of several years at millimetre and centimetre wavelengths, using the Australia Telescope Compact Array (ATCA). The new ATCA 7 mm system was also used to observe CS Cha at 7 mm. Results. WW Cha was detected on several occasions at 7 and 16 mm. We obtained one detection of WW Cha at 3.5 cm and upper limits only for 6.3 cm. The emission at 16 mm was stable over periods of days, months, and years, whereas the emission at 3.5 cm is found to be variable. A second young stellar object, Ced 112 IRS 4, was found in the field of WW Cha at 16 mm. RU Lup was detected at 7 mm. It was observed at 16 mm three times and at 3 and 6 cm four times and found to be variable in all three wavebands. CS Cha was detected at 7 mm, but the signal-to-noise ratio was not high enough to resolve the gap in the circumbinary disc. The typical resolution of the 7 and 16 mm observations was 5-10 arcsec with rms ∼0.2 mJy. Conclusions. The emission at 3, 7, and 16 mm for WW Cha is explained well by thermal emission from millimetre and centimetre-sized "pebbles". The cm spectral index between 3.5 and 6.3 cm is consistent with the emission from an optically-thick ionised wind, although the high variability of the cm emission points to a non-thermal contribution. The spectral energy distributions of both RU Lup and CS Cha from 1 to 7 mm are consistent with thermal emission from mm-sized grains. The variability of the longer-wavelength emission for RU Lup and the negative spectral index suggests non-thermal emission, arising from an optically-thin plasma.
Imaging of transplanted islets by positron emission tomography, magnetic resonance imaging, and ultrasonography

While islet transplantation is considered a useful therapeutic option for severe diabetes mellitus (DM), the outcome of this treatment remains unsatisfactory. This is largely due to the damage and loss of islets in the early transplant stage. Thus, it is important to monitor the condition of the transplanted islets, so that a treatment can be selected to rescue the islets from damage if needed. Recently, numerous trials have been performed to investigate the efficacy of different imaging modalities for visualizing transplanted islets. Positron emission tomography (PET) and magnetic resonance imaging (MRI) are the most commonly used imaging modalities for this purpose. Some groups, including ours, have also tried to visualize transplanted islets by ultrasonography (US). In this review article, we discuss the recent progress in islet imaging.
Expression of functional luteinizing hormone (LH) receptor and its messenger ribonucleic acid in bovine endometrium: LH augmentation of cAMP and inositol phosphate in vitro and human chorionic gonadotropin (hCG) augmentation of peripheral prostaglandin in vivo.

Bovine endometrium contains LH/hCG binding sites and LH increases endometrial production of prostaglandin H synthase-2 (PGHS-2) and prostaglandin synthesis. This study showed that uterine endometrium contained both LH receptor mRNA transcript and a 93-kDa immunoreactive protein that bound to anti-rat LH receptor antibody. LH receptor and its mRNA were expressed maximally in the endometrium of cows from the luteal phase compared to the follicular phase of the estrous cycle. Furthermore, there was a response shown when incubation of endometrial minces from both pre-estrus/estrus and luteal phase (but not post-ovulatory phase) with LH or oxytocin (20 ng/ml) that resulted in a significant (p<0.02) increase in cAMP and total inositol phosphates. When Day 15 cows were injected i.v. with 3000 units hCG, the increase in peripheral 13,14-dihydro-15-keto PGF(2alpha) was 2.5-fold higher than saline controls or oxytocin. We conclude that LH stimulates endometrial cAMP and total inositol phosphates which results in increased formation of uterine PGHS-2 similar to LH effect on ovarian PGHS-2. The increased 13,14-dihydro-15-keto PGF(2alpha) production induced in vivo by injections of hCG indicates that LH may have a reinforcing role in luteolysis.
Cell Extract-Containing Medium for Culture of Intracellular Fastidious Bacteria

ABSTRACT The culture of fastidious microorganisms is a critical step in infectious disease studies. As a proof-of-concept experiment, we evaluated an empirical medium containing eukaryotic cell extracts for its ability to support the growth of Coxiella burnetii. Here, we demonstrate the exponential growth of several bacterial strains, including the C. burnetii Nine Mile phase I and phase II strains, and C. burnetii isolates from humans and animals. Low-oxygen-tension conditions and the presence of small hydrophilic molecules and short peptides were critical for facilitating growth. Moreover, bacterial antigenicity was conserved, revealing the potential for this culture medium to be used in diagnostic tests and in the elaboration of vaccines against C. burnetii. We were also able to grow the majority of previously tested intracellular and fastidious bacterial species, including Tropheryma whipplei, Mycobacterium bovis, Leptospira spp. , Borrelia spp. , and most putative bioterrorism agents. However, we were unable to culture Rickettsia africae and Legionella spp. in this medium. The versatility of this medium should encourage its use as a replacement for the cell-based culture systems currently used for growing several facultative and putative intracellular bacterial species.
Algorithms for Drug Sensitivity Prediction

Precision medicine entails the design of therapies that are matched for each individual patient. Thus, predictive modeling of drug responses for specific patients constitutes a significant challenge for personalized therapy. In this article, we consider a review of approaches that have been proposed to tackle the drug sensitivity prediction problem especially with respect to personalized cancer therapy. We first discuss modeling approaches that are based on genomic characterizations alone and further the discussion by including modeling techniques that integrate both genomic and functional information. A comparative analysis of the prediction performance of four representative algorithms, elastic net, random forest, kernelized Bayesian multi-task learning and deep learning, reflecting the broad classes of regularized linear, ensemble, kernelized and neural network-based models, respectively, has been included in the paper. The review also considers the challenges that need to be addressed for successful implementation of the algorithms in clinical practice.
Who Prefers to Work with Whom? Trait Activation in Classroom Teams

Trait activation theory (Tett & Burnett, 2003) predicts that individuals should prefer working with others offering cues for trait expression. Working in 3- to 6-member teams, 43 undergraduates completed a personality questionnaire and rated preference in working with each other on class projects, yielding 294 unique rater-ratee pairs. Significant rater-ratee trait interactions were obtained in 12 of 36 pairwise combinations of achievement, affiliation, autonomy, dominance, abasement, and defendence (e.g., rater affiliation by ratee dominance), with 9 of 20 hypothesized directional effects significant (p < .05). Results suggest a chain reaction of trait activation: team tasks activate ratee achievement, affiliation, and dominance, whose expressions trigger raters' trait-based reactions. Affiliative ratees were preferred by raters with abrasive traits (e.g., high defendence), suggesting that people seek coworkers offering cues to express desirable traits and avoid those provoking expression of undesirable traits. Numerous complexities involving trait expression at work offer directions for future research. [150 words]
Steady and unsteady natural circulation in a single-phase 2 D-annular loop

In this study, natural convection in a 2D-annular closed-loop thermosyphon filled with water is numerically investigated. The loop is heated at a constant flux over the bottom half and cooled at a constant temperature over the top half. It is numerically demonstrated that the complexity of the dynamic properties experimentally encountered in loops is also found here: steady flow with and without recirculating regions, periodic motion and Lorenz-like chaotic flow. The present numerical experiment also corroborates the fact that forced flow correlations are assumed to be applicable for natural circulation flow. The dimensionless group, Grm(Dh/L), proposed by Vijayan and Austregesilo [13] for the mass flow rate gives very good results in the case of annular loop even for various Prandtl numbers.

The Role of Anger in Symptoms and Processes of Generalized Anxiety Disorder

Research investigating the associations between anger and symptoms of generalized anxiety disorder (GAD) is limited. The goals of the current program of research were to examine the various forms of anger associated with GAD as well as the cross-over effects of worry and anger on cognitive mechanisms characteristic of GAD and high trait anger. In Study 1, participants (N = 381) completed a series of questionnaires assessing various aspects of anger and GAD diagnostic criteria via self-report. Our results indicated that GAD analogues reported higher levels of trait anger, anger suppression, and hostility than less anxious participants. In Study 2, the effects of laboratory-induced anger on negative style, negative beliefs about uncertainty, and worry were examined. Participants were randomized to an anger induction condition (n = 43) or a control condition (n = 34). An interpretation bias task, questionnaire items assessing beliefs about uncertainty, and a structured worry task were administered following the manipulation. Participants in the anger condition reported greater increases in negative interpretive style and in the belief that uncertainty is unfair and spoils everything than participants in the control condition; however no group differences were found with worry. In Study 3, the effects of anger and worry on interpretive style and hostile attributions were examined. Participants were randomized to a worry induction (n = 51), anger induction (n = 50), or control condition (n = 49). We also examined whether GAD analogues reported greater hostile interpretations of ambiguous intent than less anxious participants, and whether GAD analogue status interacted with the worry and anger experimental conditions in predicting increased hostile and threatening interpretations of ambiguous information. Although we found no effects of condition or interactions between GAD and condition on interpretive style or hostile attributions, we found that GAD symptoms were associated with greater negative interpretive style and greater hostile attributions. Together, findings from these studies suggest that elevated levels of multiple dimensions of anger, as well as hostile attributions, characterize individuals who meet diagnostic criteria for GAD and provide some, albeit limited, support for the notion that elevated anger contributes to cognitive vulnerabilities underlying GAD.
