Dissipation in the Bay of Bengal from a Seaglider

<p>In July 2016, a Seaglider equipped with a microstructure sensor system was deployed in the southern Bay of Bengal at 7° 54.0′ N, 89° 4.5′ E.  162 profiles (of which 146 were to 1000 m) of microstructure shear and temperature were collected as a time series at the same location.  Dissipation is calculated independently from both shear and temperature.  The time-average profile shows high dissipation (nearly 1×10<sup>-5</sup> W kg<sup>-1</sup>) near the surface, dropping rapidly over the uppermost 50 m to ~1×10<sup>-7</sup> W kg<sup>-1</sup>, followed by a more gradual decrease to ~5×10<sup>-10</sup> W kg<sup>-1</sup> at 300m.  A band of slightly higher dissipation around 500 m (~8×10<sup>-10</sup> W kg<sup>-1</sup>) could facilitate an increased vertical flux of nutrients, heat, salinity, etc at these depths.  From 600 to 1000 m dissipation remains roughly constant at ~1×10<sup>-10</sup> W kg<sup>-1</sup>.  Variability of the near surface dissipation in response to atmospheric forcing is also discussed.</p>

Following the Trail of eSports

Despite eSports' relatively long history, the attention paid by academia to this phenomenon has been much more recent and is still in an embryonic state in all of the views. The scientific production has grown because of the global success associated with the widespread growth of live events and the large following of competitions retransmitted via streaming. This article aims to offer a literature review of the research carried out on eSports to date, based upon a systematic review on the sample of selected research. The results confirm the growing variety of approaches to the issue, but also a clear dominance of computer science perspectives rather than to sport science or game studies. While showing some balance between qualitative and quantitative approaches, the prevalence of theoretical perspectives may be taken as a sign of struggle for consolidation as a field. Finally, a discussion about main matters and an author and institution average profile are also provided.

GENDER DIFFERENCES EXAMINED IN THE PSYCHOPHYSIOLOGICAL EVALUATION IN RESPECT OF THE PRISON STUFF ACROSS THE SERVICE

В статье рассматриваются актуальные вопросы обследования на полиграфе мужчин и женщин - сотрудников уголовно-исполнительной системы в рамках кадровых перемещений. С учетом имеющихся в психологической науке данных описывается ряд характерологических особенностей, в которых были обнаружены традиционные гендерные различия. Акцентируется внимание на учете специалистом-полиграфологом типовых моделей поведения обследуемых в процессе предтестовой беседы и тестирования на полиграфе с позиций гендерных различий персонала уголовно-исполнительной системы. Приведена практика проведения специальных психофизиологических исследований в отношении мужчин и женщин - сотрудников УФСИН России по Томской области, назначаемых на должности среднего начальствующего состава. Составлен психологический портрет усредненного профиля обследуемых по результатам психодиагностического обследования и инструментальной детекции лжи с применением полиграфа. При взаимодействии со специалистом-полиграфологом для обследуемых женщин характерен выбор демонстративной модели поведения, для мужчин характерен выбор сдержанно-корректного стиля поведения. Выявлена взаимосвязь между выбором модели поведения обследуемого на полиграфе лица и пола специалиста, осуществляющего опрос. Формулируется вывод о том, что учет гендерных различий обследуемых окажет помощь специалисту-полиграфологу в плане прогноза поведения тестируемых сотрудников в процессе полиграфной проверки, позволит сузить круг намеренно скрываемых ими факторов риска. The article deals with topical issues of polygraph examination of men and women employees of the criminal Executive system in the framework of personnel transfers. Taking into account the data available in psychological science, a number of characterological features are described, in which traditional gender differences were found. Attention is paid to the consideration by a polygraph specialist of typical behavior patterns in the process of pre-test conversation and polygraph testing from the perspective of gender differences in the personnel of the penal system. The practice of conducting special psychophysiological research in relation to men and women - employees of the Federal penitentiary service of Russia in the Tomsk region, appointed to the positions of middle management staff. A psychological portrait of the average profile of the subjects was compiled based on the results of psychodiagnostic examination and instrumental lie detection using a polygraph. When interacting with a specialist polygraph examiner, women are characterized by the choice of a demonstrative behavior model, while men are characterized by the choice of a reserved and correct behavior style. The relationship between the choice of the behavior model of the person being examined on a polygraph and the gender of the specialist conducting the survey is revealed. The conclusion is formulated that taking into account the gender differences of the subjects will help the polygraph specialist in terms of predicting the behavior of tested employees in the process of polygraph testing, will narrow the range of deliberately hidden risk factors.

Detection of giant pulses in PSR J1047−6709

We report the emission variations in PSR J1047−6709 observed at 1369 MHz using the Parkes 64 m radio telescope. This pulsar shows two distinct emission states: a weak state and a bright emission state. We detected giant pulses (GPs) in the bright state for the first time. We found 75 GPs with pulse width ranging from 0.6 to 2.6 ms. The energy of GPs follows a power-law distribution with the index α = −3.26 ± 0.22. The peak flux density of the brightest GP is 19 Jy which is 110 times stronger than the mean pulse profile. The polarization properties of the average profile of GPs are similar to that of the pulses with energy less than 10 times average pulse energy in the bright state. This indicates that the emission mechanism is basically the same for them. Our results provide a new insight into the origin of the GPs in pulsars.

Influence of Scanner Precision and Analysis Software in Quantifying Three-Dimensional Intraoral Changes: Two-Factor Factorial Experimental Design

Background Three-dimensional scans are increasingly used to quantify biological topographical changes and clinical health outcomes. Traditionally, the use of 3D scans has been limited to specialized centers owing to the high cost of the scanning equipment and the necessity for complex analysis software. Technological advances have made cheaper, more accessible methods of data capture and analysis available in the field of dentistry, potentially facilitating a primary care system to quantify disease progression. However, this system has yet to be compared with previous high-precision methods in university hospital settings. Objective The aim of this study was to compare a dental primary care method of data capture (intraoral scanner) with a precision hospital-based method (laser profilometer) in addition to comparing open source and commercial software available for data analysis. Methods Longitudinal dental wear data from 30 patients were analyzed using a two-factor factorial experimental design. Bimaxillary intraoral digital scans (TrueDefinition, 3M, UK) and conventional silicone impressions, poured in type-4 dental stone, were made at both baseline and follow-up appointments (mean 36 months, SD 10.9). Stone models were scanned using precision laser profilometry (Taicaan, Southampton, UK). Three-dimensional changes in both forms of digital scans of the first molars (n=76) were quantitatively analyzed using the engineering software Geomagic Control (3D Systems, Germany) and freeware WearCompare (Leeds Digital Dentistry, UK). Volume change (mm3) was the primary measurement outcome. The maximum point loss (μm) and the average profile loss (μm) were also recorded. Data were paired and skewed, and were therefore compared using Wilcoxon signed-rank tests with Bonferroni correction. Results The median (IQR) volume change for Geomagic using profilometry and using the intraoral scan was –0.37 mm3 (–3.75-2.30) and +0.51 mm3 (–2.17-4.26), respectively (P<.001). Using WearCompare, the median (IQR) volume change for profilometry and intraoral scanning was –1.21 mm3 (–3.48-0.56) and –0.39 mm3 (–3.96-2.76), respectively (P=.04). WearCompare detected significantly greater volume loss than Geomagic regardless of scanner type. No differences were observed between groups with respect to the maximum point loss or average profile loss. Conclusions As expected, the method of data capture, software used, and measurement metric all significantly influenced the measurement outcome. However, when appropriate analysis was used, the primary care system was able to quantify the degree of change and can be recommended depending on the accuracy needed to diagnose a condition. Lower-resolution scanners may underestimate complex changes when measuring at the micron level.

Average Joe, Crooked Hillary and the unStable Narcissist: Expert Impressions of 2016 and 2020

The U.S. 2020 presidential election has, like the 2016 election, brought attention to the two candidates’ personalities. We invited HEXACO researchers to complete observer-report inventories for Joe Biden’s and Donald Trump’s public personalities. Given previous comparison of Hillary Clinton and Donald Trump prior to the 2016 election, we are also able to compare the 2020 candidates to the 2016 candidates. Our ratings reveal a relatively average profile of personality traits for Joe Biden, including higher ratings than Trump for Honesty-Humility, Agreeableness, Extraversion, and Conscientiousness. Biden also scores higher on all traits than Clinton other than her slightly higher scores for Conscientiousness and Openness. In comparison to his 2016 ratings, in 2020 Trump is rated as having lower Extraversion and much lower Conscientiousness along with higher Emotionality (especially Fearfulness). Overall, our data once again suggest a Narcissistic profile for Trump, with elements of psychopathic personality traits, while Biden presents as an outgoing individual with slightly above average prosocial traits.

Populations of filaments from the distribution of galaxies in numerical simulations

We present a statistical study of the filamentary structures of the cosmic web in the large hydro-dynamical simulations Illustris-TNG, Illustris, and Magneticum at redshift z = 0. We focus on the radial distribution of the galaxy density around filaments detected using the Discrete Persistent Structure Extractor (DisPerSE). We show that the average profile of filaments presents an excess of galaxy density (> 5σ) up to radial distances of 27 Mpc from the core. The relation between galaxy density and the length of filaments is further investigated showing that short (Lf < 9 Mpc) and long (Lf ≥ 20 Mpc) filaments are two statistically different populations. Short filaments are puffier, denser, and more connected to massive objects, whereas long filaments are thinner, less dense, and more connected to less massive structures. These two populations trace different environments and may correspond to bridges of matter between over-dense structures (short filaments), and to cosmic filaments shaping the skeleton of the cosmic web (long filaments). Through Markov chain Monte Carlo (MCMC) explorations, we find that the density profiles of both short and long filaments can be described by the same empirical models (generalised Navarro, Frenk and White, β-model, a single and a double power law) with different and distinct sets of parameters.

Jovem, dedicado, confinado e prejudicado: perfis, rotinas e processos jornalísticos durante a pandemia de Covid-19

The work features professional profiles and productive routines of journalists involved in the coverage of the new Coronavirus pandemic in June 2020. The theoretical body deals with production processes, professional profilesand work routines in newsrooms. The methodology used is the bibliographic review for generating a survey and its composition for collecting a non-probabilistic sample. It is concluded that the average profile of the show is that of a young man from São Paulo, who, working at home office, increased his dedication time, produced news about Covid-19 even without specialization in the subject, used two to three sources per content, and suffered some constraint or impediment to carry out the journalistic craft.

The Variation of Geomagnetic Storm Duration with Intensity

Variability in the near-Earth solar wind conditions can adversely affect a number of ground- and space-based technologies. Such space-weather impacts on ground infrastructure are expected to increase primarily with geomagnetic storm intensity, but also storm duration, through time-integrated effects. Forecasting storm duration is also necessary for scheduling the resumption of safe operating of affected infrastructure. It is therefore important to understand the degree to which storm intensity and duration are correlated. The long-running, global geomagnetic disturbance index, $\mathit{aa}$aa, has recently been recalibrated to account for the geographic distribution of the component stations. We use this $\mathit{aa}_{H}$aaH index to analyse the relationship between geomagnetic storm intensity and storm duration over the past 150 years, further adding to our understanding of the climatology of geomagnetic activity. Defining storms using a peak-above-threshold approach, we find that more intense storms have longer durations, as expected, though the relationship is nonlinear. The distribution of durations for a given intensity is found to be approximately log-normal. On this basis, we provide a method to probabilistically predict storm duration given peak intensity, and test this against the $\mathit{aa}_{H}$aaH dataset. By considering the average profile of storms with a superposed-epoch analysis, we show that activity becomes less recurrent on the 27-day timescale with increasing intensity. This change in the dominant physical driver, and hence average profile, of geomagnetic activity with increasing threshold is likely the reason for the nonlinear behaviour of storm duration.
