The perceived exertion threshold (PET) corresponds to the critical power and to an indicator of maximal oxygen uptake steady state

The perceived exertion has been a target of several investigations, many times with association with objective physiological indicators in exercise. Recently, the identification of the perceived exertion threshold (PET) was proposed in the water running, which presented no difference in relation to the critical velocity. Theoretically, both parameters would be indicators of the maximum steady state of variables such as VO 2 and blood lactate. The objective of this work was to verify the coincidence between PET, critical power (PCrit) and an indicator of maximum VO 2 steady state (PCrit’) in cycle ergometer. Eight male participants were submitted to progressive effort test in order to determine VO 2peak (46.7 ± 8.5 ml/kg/ min) and to four rectangular tests until exhaustion for the estimation of the critical power model parameters, PET and PCrit’. The hyperbolic relation between mechanical power and time spent for the VO 2peak to be reached in each test was used for the PCrit’ estimation, considered as the asymptote in the power axis, and the portion of the anaerobic work capacity (CTAnaer) depleted up to the establishment of the VO 2peak (CTAnaer’). In order to identify PET, the straight lines angular coefficients of the perceived exertion in time (ordinate) and the powers used (abscissa) were adjusted to a linear function that provided a point in the power axis in which the perceived exertion would be kept indefinitely stable. The parameters PCrit and CTAnaer were estimated by means of the power-time non-linear equation. In order to compare the estimations of PET, PCrit and PCrit’, the analysis of variance ANOVA was employed for repeated measurements, and the associations were established through the Pearson correlation. CTAnaer and CTAnaer’ were compared through the t test. PET (180 ± 61), PCrit (174 ± 43) and PCrit’ (176 ± 48) were not significantly different and the correlations were of 0.92-0.98. CTAnaer’ (14,080 ± 5,219 J) was lower than CTAnaer (22,093 ± 9,042 J). One concludes that the PET predicts the intensity of PCrit and PCrit’ with accuracy.
Neutrino probes of the nature of light dark matter

Dark matter particles gravitationally trapped inside the Sun may annihilate into Standard Model particles, producing a flux of neutrinos. The prospects of detecting these neutrinos in future multi-kt neutrino detectors designed for other physics searches are explored here. We study the capabilities of a 34/100 kt liquid argon detector and a 100 kt magnetized iron calorimeter detector. These detectors are expected to determine the energy and the direction of the incoming neutrino with unprecedented precision allowing for tests of the dark matter nature at very low dark matter masses, in the range of 10–25 GeV. By suppressing the atmospheric background with angular cuts, these techniques would be sensitive to dark matter-nucleon spin-dependent cross sections at the fb level, reaching down to a few ab for the most favorable annihilation channels and detector technology.
Recent Developments in Testing Base Isolation Systems

One of these developments has been the ability to test large scale isolation systems using simulated seismic loads. These tests have not only proven the performance and reliability of the isolation systems and hardware, but have enabled correlation studies to be undertaken which have confirmed the accuracy of analytical methods and the acceptability of current design procedures. Component tests on single isolators are described. Tests on plain and filled natural rubber bearings, lead-rubber bearings, sliding bearings and bearings incorporating uplift resistance mechanisms have been performed. High shear strain tests on large (up to full-scale) elastomeric bearings have been conducted to determine the stability characteristics and limit states of the isolators. Performance evaluation studies using the earthquake simulator to test large scale model isolated structures have been carried out for a variety of isolation systems and structures. Uplift studies of slender base isolated buildings and the investigation of the behavior of base isolated skew bridge decks have been studied. This paper aims to highlight those areas where progress has been made.
Constraining running non-gaussianity

The primordial non-Gaussian parameter fNL has been shown to be scale-dependent in several models of inflation with a variable speed of sound, such as Dirac-Born-Infeld (DBI) models. We perform a Fisher matrix analysis of the bispectra of the temperature and polarization of the Cosmic Microwave Background (CMB) radiation and derive the expected constraints on the parameter nNG that quantifies the running of fNL(k) for current and future CMB missions. We find that CMB information alone, in the event of a significant detection of the non-Gaussian component, corresponding to fNL = 50 for the local model and fNL = 100 for the equilateral model of non-Gaussianity, is able to determine nNG with a 1-σ uncertainty of nNG ≃ 0.1 and ΔnNG ≃ 0.3, respectively, for the Planck mission and a factor of two better for CMBPol. In addition, we show how future large-scale structure observations should achieve results comparable to or even better than those from the CMB, while showing some complementarity due to the different distribution of the non-Gaussian signal over the relevant range of scales. Finally, we compare our findings to the predictions on the amplitude and running of non-Gaussianity of DBI inflation, showing how the constraints on a scale-dependent fNL(k) translate into constraints on the parameter space of the theory.
Node Mapping Criterion for Highly Saturated Interior PMSMs Using Magnetic Reluctance Network

Interior Permanent Magnet Synchronous Machine (IPMSM) are high torque density machines that usually work under heavy load conditions, becoming magnetically saturated. To obtain properly their performance, this paper presents a node mapping criterion that ensure accurate results when calculating the performance of a highly saturated IPMSM via a novel magnetic reluctance network approach. For this purpose, a Magnetic Circuit Model (MCM) with variable discretization levels for the different geometrical domains is developed. The proposed MCM caters to V-shaped IPMSMs with variable magnet depth and angle between magnets. Its structure allows static and dynamic time stepping simulations to be performed by taking into account complex phenomena such as magnetic saturation, cross-coupling saturation effect and stator slotting effect. The results of the proposed model are compared to those obtained by Finite Element Method (FEM) for a number of IPMSMs obtaining excellent results. Finally, its accuracy is validated comparing the calculated performance with experimental results on a real prototype.
Non-local gravity and comparison with observational datasets. II. Updated results and Bayesian model comparison with ΛCDM

We present a comprehensive and updated comparison with cosmological observations of two non-local modifications of gravity previously introduced by our group, the so called RR and RT models. We implement the background evolution and the cosmological perturbations of the models in a modified Boltzmann code, using CLASS. We then test the non-local models against the Planck 2015 TT, TE, EE and Cosmic Microwave Background (CMB) lensing data, isotropic and anisotropic Baryonic Acoustic Oscillations (BAO) data, JLA supernovae, H0 measurements and growth rate data, and we perform Bayesian parameter estimation. We then compare the RR, RT and ΛCDM models, using the Savage-Dickey method. We find that the RT model and ΛCDM perform equally well, while the performance of the RR model with respect to ΛCDM depends on whether or not we include a prior on H0 based on local measurements.
A non-Gaussian landscape

Primordial perturbations with wavelengths greater than the observable universe shift the effective background fields in our observable patch from their global averages over the inflating space. This leads to a landscape picture where the properties of our observable patch depend on its location and may significantly differ from the expectation values predicted by the underlying fundamental inflationary model. We show that if multiple fields are present during inflation, this may happen even if our horizon exit would be preceded by only a few e-foldings of inflation. Non-Gaussian statistics are especially affected: for example models of local non-Gaussianity predicting |fNL0| >> 10 over the entire inflating volume can have a probability up to a few tens of percent to generate a non-detectable bispectrum in our observable patch |fNLobs. |≲10. In this work we establish systematic connections between the observable local properties of primordial perturbations and the global properties of the inflating space which reflect the underlying high energy physics. We study in detail the implications of both a detection and non-detection of primordial non-Gaussianity by Planck, and discover novel ways of characterising the naturalness of different observational configurations.
SOME RESULTS ON FIXED POINTS IN UNIFORM SPACES

2. Preliminary definitions and results Let (X, E2}’) be a uniform space. A net $\{x_{n} ; n\in D, \geq\}$ in $X$ is said to converge to an element $x$ in $X$ if for every member $U$ in $\ovalbox{\tt\small REJECT}$, there is an element $N$ in $D$ such that $(x., x)eU$ for all $n$ in $D$ with $n\geq N$. A net $\{x_{n} ; neD, \geq\}$ is said to be a Cauchy net if for every $U$ in Zl, there is an element $N$ in $D$ such that
Simulations of elementary processes in entangled wormlike micelles under tension: a kinetic pathway to Y-junctions and shear induced structures

The merging process of two amphiphilic cylindrical micelles has been simulated using a coarse grained model in which amphiphiles are represented as chains of one head particle and four tail particles. In our set-up with twisted boundary conditions, a ring-shaped worm is effectively entangled with itself. Upon stretching the box, putting the worms under tension, a fusion into an H-like structure is observed, which eventually transforms into an almost tensionless structure with two freely gliding Y-junctions. The tensions on the worms never reach the point where scission becomes an alternative to fusion. We end with a short discussion of the possible implications of these observations.
Dual Antenna Design for a Novel Airborne Probe

This work outlines the design, simulation, and testing of a dual antenna design for a novel airborne probe. The airborne probe is known as the Global Sense eMote and is designed to collect in-situ atmospheric data and transmit the data back to a receiver base station. The eMote operates in the industrial, scientific, and medical band, 902 – 928 MHz. The eMote is designed to replace the larger, more costly current environmental data collection devices currently on the market. The final antennas designed were two planar inverted-F antennas on a compact, circular FR-4 printed circuit board. This work outlines the methodologies used to select and design the antennas. The antennas were simulated and designed in ANSYS HFSS and ANSYS Electronics Desktop. The fabricated antennas were then tested to determine how well their performance correlated with the simulated antennas. The antennas did not perform as well as the simulation implied so the causes were determined and the process to extract the differences was detailed. Finally, potential antenna improvements and future work are presented.
A BAYESIAN APPROACH TO LOCATING THE RED GIANT BRANCH TIP MAGNITUDE. II. DISTANCES TO THE SATELLITES OF M31

In “A Bayesian Approach to Locating the Red Giant Branch Tip Magnitude (Part I),” a new technique was introduced for obtaining distances using the tip of the red giant branch (TRGB) standard candle. Here we describe a useful complement to the technique with the potential to further reduce the uncertainty in our distance measurements by incorporating a matched-filter weighting scheme into the model likelihood calculations. In this scheme, stars are weighted according to their probability of being true object members. We then re-test our modified algorithm using random-realization artificial data to verify the validity of the generated posterior probability distributions (PPDs) and proceed to apply the algorithm to the satellite system of M31, culminating in a three-dimensional view of the system. Further to the distributions thus obtained, we apply a satellite-specific prior on the satellite distances to weight the resulting distance posterior distributions, based on the halo density profile. Thus in a single publication, using a single method, a comprehensive coverage of the distances to the companion galaxies of M31 is presented, encompassing the dwarf spheroidals Andromedas I–III, V, IX–XXVII, and XXX along with NGC 147, NGC 185, M33, and M31 itself. Of these, the distances to Andromedas XXIV–XXVII and Andromeda XXX have never before been derived using the TRGB. Object distances are determined from high-resolution tip magnitude posterior distributions generated using the Markov Chain Monte Carlo technique and associated sampling of these distributions to take into account uncertainties in foreground extinction and the absolute magnitude of the TRGB as well as photometric errors. The distance PPDs obtained for each object both with and without the aforementioned prior are made available to the reader in tabular form. The large object coverage takes advantage of the unprecedented size and photometric depth of the Pan-Andromeda Archaeological Survey. Finally, a preliminary investigation into the satellite density distribution within the halo is made using the obtained distance distributions. For simplicity, this investigation assumes a single power law for the density as a function of radius, with the slope of this power law examined for several subsets of the entire satellite sample.
Sample Design for Domain Calibration Estimators

The phenomenon of nonresponse in a sample survey reduces the precision of parameters estimates and increases bias in estimates resulting in larger mean square error, thus ultimately reducing their efficiency. An important technique to address these problems is by calibration. We proposed calibration estimators for totals of domain of study. Sample designs and in particular sample sizes are chosen so as to provide reliable estimates for domains of study. But budget and other constraints usually prevent the allocation of sufficiently large samples to domains to provide reliable estimates using traditional statistical techniques. We have developed an approach for finding the best sample design for the domain calibration estimators subject to a cost constraint and derived optimum stratum sample sizes that minimized the variances of the proposed domain calibration estimators and reduced the objective function. The efficacy of the proposed domain calibration estimators was tested through a real data analysis. Results of the analytical study using real data showed that our proposed domain calibration estimator is substantially superior to the traditional GREG-estimator with relatively small bias, mean square error and average length of confidence interval.
FERTILIZER METERING MECHANISM WITH HELICAL CONIC CYLINDRICAL THREAD FOR FAMILY AGRICULTURE

Small rural properties are important for Brazilian agribusiness, however, there are few suitable equipment to distribute fertilizers for this establishments. This study aims to present a new fertilizer doser for family agriculture, in which we united a helical conic thread with a conventional fertilizer doser of cylindrical section. Experimental planning was carried out by a 24 factorial design. An analysis of variance (ANOVA) was also conducted. The mechanism showed a positive result regarding the uniformity of fertilizer flow with a coefficient of variation of 3.1 to 5.8%, in longitudinal distribution with a 4% coefficient of variation, and also for different types of fertilizers, in which variations between 2.7 and 3.5% were found.

Sauen durchlaufen wahrend des Produktionszyklus verschiedene Haltungssysteme im Deckstall, Wartestall und Abferkelstall. Um den Einfluss des Bodenbelags auf die Klauengesundheit in den verschiedenen Haltungsabschnitten zu untersuchen, wurden die Sauen am Bildungs- und Wissenszentrum Boxberg, Landesanstalt fur Schweinezucht und Schweinehaltung (LSZ) in regelmasigen Abstanden im Abferkelstall, im Deckzentrum und in der Wartehaltung bonitiert. Die Ergebnisse von uber 1 300 Bonituren zeigen, dass in der Gruppenhaltung vor allem die Sohle und der Ballen hoheren Belastungen ausgesetzt sind. Verletzungen am Wandhorn entstehen uberwiegend auf Spaltenboden im Liegebereich. Im Abferkelstall wahrend der Einzelhaltung zeigt sich hingegen eine mangelhafte Abnutzung der Klauen.
On the cellular mechanisms underlying working memory capacity in humans

The cellular processes underlying individual differences in the Working Memory Capacity (WMC) of humans are essentially unknown. Psychological experiments suggest that subjects with lower working memory capacity (LWMC), with respect to subjects with higher capacity (HWMC), take more time to recall items from a list because they search through a larger set of items and are much more susceptible to interference during retrieval. However, a more precise link between psychological experiments and cellular properties is lacking and very difficult to investigate experimentally. In this paper, we investigate the possible underlying mechanisms at the single neuron level by using a computational model of hippocampal CA1 pyramidal neurons, which have been suggested to be deeply involved in the recognition of specic items. The model makes a few experimentally testable predictions on the cellular processes underlying the cumulative latency in delayed free recall experimentally observed in humans under different testing conditions. The results suggest, for the rst time, a physiologically plausible explanation for individual performances, and establish a proof of principle for the hypothesis that HWMC individuals use a larger portion of the apical tree with a correlated higher level of synaptic background noise.
The Mid-Infrared Instrument for the James Webb Space Telescope, IV: The Low-Resolution Spectrometer

The low-resolution spectrometer of the MIRI, which forms part of the imager module, will provide R ∼ 100 long-slit and slitless spectroscopy from 5 to 12 μm. The design is optimized for observations of compact sources, such as exoplanet host stars. We provide here an overview of the design of the LRS, and its performance as measured during extensive test campaigns, examining in particular the delivered image quality, dispersion, and resolving power, as well as spectrophotometric performance, flatfield accuracy, and the effects of fringing. We describe the operational concept of the slitless mode, which is optimally suited to transit spectroscopy of exoplanet atmospheres. The LRS mode of the MIRI was found to perform consistently with its requirements and goals.
Adherence to Hydroxyurea Therapy in Patients with Sickle Cell Disease at King Khalid University Hospital in Riyadh

Background: Sickle cell disease is associated with several systemic complications and life-threatening crises. The use of drugs that increase hemoglobin F level, such as hydroxyurea, in patients with sickle cell disease is associated with a reduction in the severity of the disease. Aim: To compare the outcome of patients adherent to hydroxyurea with those who are poorly adherent and to determine which age group is more likely to be poorly adherent and hence suffer more complications. Subjects and Methods: A cross-sectional study was performed at King Khalid University Hospital in Riyadh between January 01 and March 31, 2014. The study included 140 patients, 60 of them were receiving hydroxyurea therapy. Results: Patients who were adherent to hydroxyurea treatment suffered less complications and had less frequent sickling crises than patients who were poorly adherent to therapy. Patients belonging to the age group 15 to 30 years were found to be less adherent to treatment than other age groups and consequently they suffered more complications. Conclusion: More attention and health education should be offered to adolescents and young adults having sickle cell anemia in order for these patients to benefit from the positive impact of hydroxyurea on the disease outcome.

The effects of virtual industrial training on mental workload during task performance

This research examines the impact of task complexity, experience level, hazard perception, and simulated tool breakage on an overall mental workload rating. In this study, 100 participants were tested after using a desktop virtual reality training system that simulated a Computer Numerical Control (CNC) milling operation. Differences based on hazard perception and retention interval were also considered. Training conditions were varied for the participants so that the contribution of visual cues, auditory cues, and written instructions could be tested. The participants were asked to determine the best machining outcome during the training period. Results were consistent with previous literature and indicated that the overall mental workload was significantly influenced by task complexity and experience level. Results also suggested that hazard perception as new contributor could be added to the mental workload model for an industrial task of this type. Moreover, the impact of simulated tool breakage on performance was investigated, and it was found that performance was significantly affected by the presence of simulated tool breakage. © 2010 Wiley Periodicals, Inc.
