description: We analyze theoretically the dynamics of aeolian sand ripples. In order to put the study in the context we first review existing models. We argue on the local character of sand ripple formation. Using a hydrodynamical model we derive a nonlinear equation for the sand profile. We show how the hydrodynamical model may be modified to recover the missing terms that are dictated by symmetries. The symmetry and conservation arguments are powerful in that the form of the equation is model-independent. We then present an extensive numerical and analytical analysis of the generic sand ripple equation. We find that at the initial stage the wavelength of the ripple is that corresponding to the linearly most dangerous mode. At later stages the profile undergoes a coarsening process leading to a significant increase of the wavelength. We find that including the next higher order nonlinear term in the equation, leads naturally to a saturation of the local slope. We analyze both analytically and numerically the coarsening stage, in terms of a dynamical exponent for the mean wavelength increase. We discuss some future lines of investigations.

description: Across the empirical sciences, few statistical procedures rival the popularity of the frequentist t-test. In contrast, the Bayesian versions of the t-test have languished in obscurity. In recent years, however, the theoretical and practical advantages of the Bayesian t-test have become increasingly apparent and various Bayesian t-tests have been proposed, both objective ones (based on general desiderata) and subjective ones (based on expert knowledge). Here we propose a flexible t-prior for standardized effect size that allows computation of the Bayes factor by evaluating a single numerical integral. This specification contains previous objective and subjective t-test Bayes factors as special cases. Furthermore, we propose two measures for informed prior distributions that quantify the departure from the objective Bayes factor desiderata of predictive matching and information consistency. We illustrate the use of informed prior distributions based on an expert prior elicitation effort.

description: We report the results of a $J$-band survey for photometric variability in a sample of young, low-gravity objects using the New Technology Telescope (NTT) and the United Kingdom InfraRed Telescope (UKIRT). Surface gravity is a key parameter in the atmospheric properties of brown dwarfs and this is the first large survey that aims to test the gravity dependence of variability properties. We do a full analysis of the spectral signatures of youth and assess the group membership probability of each target using membership tools from the literature. This results in a 30 object sample of young low-gravity brown dwarfs. Since we are lacking in objects with spectral types later than L9, we focus our statistical analysis on the L0-L8.5 objects. We find that the variability occurrence rate of L0-L8.5 low-gravity brown dwarfs in this survey is $30^{+16}_{-8}\%$. We reanalyse the results of Radigan 2014 and find that the field dwarfs with spectral types L0-L8.5 have a variability occurrence rate of $11^{+13}_{-4}\%$. We determine a probability of $98\%$ that the samples are drawn from different distributions. This is the first quantitative indication that the low-gravity objects are more likely to be variable than the field dwarf population. Furthermore, we present follow-up $J_S$ and $K_S$ observations of the young, planetary-mass variable object PSO 318.5-22 over three consecutive nights. We find no evidence of phase shifts between the $J_S$ and $K_S$ bands and find higher $J_S$ amplitudes. We use the $J_S$ lightcurves to measure a rotational period of $8.45\pm0.05~$hr for PSO 318.5-22.

description: The demand of project management practices is increasing as the needs of providing value-for-money projects emerged, especially under the current unimaginable amount of economic damages due to the Coronavirus Disease 2019 (COVID-19) affecting 219 countries and territories, including Malaysia. It is acknowledged by the project management practitioners worldwide that the challenges in managing projects, which are one-off, unique and dynamic in nature, are very much contributed by the classic iron triangle that incorporates time, cost and quality. These triple constraints detrimentally impact the deliverable of the projects under the absence of effective project management practices, leading to project delays, budget overruns and poor quality. Thus, this book aims at discussing the most common approaches of project integration management, project scope management, project cost management, project resources management and project communications management of various types of construction projects, namely mega infrastructure projects, residential construction projects and public construction projects in providing the insights and trends of successful project management practices in Malaysia. This book is expected to open the eyes on the efficient and effective application of project management knowledge, skills, tools and techniques among the construction players in the Malaysian construction industry landscape, which could be replicated for other regions and similar industries as the guidance in assisting the achievement of the successful delivery of projects in general.

description: The International Agency for Research on Cancer classified welding fumes as carcinogenic to humans, and occupational exposure limits should be established to protect welders. The aim of this study is to estimate exposure levels to inhalable and respirable welding fumes by welding process to use them for exposure assessment in epidemiological studies and to derive occupational exposure limits. In total, 15,473 mass concentrations of inhalable and 9,161 concentrations of respirable welding fumes could be analyzed along with welding-related and sampling information, which were compiled in the German database MEGA between 1983 and 2016. In both particle-size fractions, model-based geometric means of the concentrations were estimated by welding process and material for frequently used welding processes adjusted for sampling time and median-centered for calendar years. The inhalable concentrations were approximately twice the respirable concentrations, with medians of 3 mg/m3 (inter-quartile range: 1.2–7.0 mg/m3) and 1.5 mg/m3 (inter-quartile range: < limit of detection −3.8 mg/m3), respectively. The adjusted geometric means of flux-cored arc welding, metal inert and active gas welding, shielded metal arc welding and torch cutting ranged from 0.9 to 2.2 mg/m3 for respirable welding fumes and from 2.3 to 4.7 mg/m3 for inhalable fumes. In both particle-size fractions, geometric means were between 0.1 and 0.9 mg/m3 when performing tungsten inert gas, autogeneous, resistance, laser, and plasma welding or spraying. Results derived from this large dataset are useful for a quantitative exposure assessment to estimate health risks of welders.

description: Nonparametric regression is a standard statistical tool with increased importance in the Big Data era. Boundary points pose additional difficulties but local polynomial regression can be used to alleviate them. Local linear regression, for example, is easy to implement and performs quite well both at interior and boundary points. Estimating the conditional distribution function and/or the quantile function at a given regressor point is immediate via standard kernel methods but problems ensue if local linear methods are to be used. In particular, the distribution function estimator is not guaranteed to be monotone increasing, and the quantile curves can “cross”. In the paper at hand, a simple method of correcting the local linear distribution estimator for monotonicity is proposed, and its good performance is demonstrated via simulations and real data examples.

Nuptial feeding and genital coupling of Neopanorpa scorpionflies (Insecta: Mecoptera: Panorpidae) with notal organs of various lengths: supplementary material

subject: Palaeontology (incl. palynology)

description: Neopanorpa,
the second largest genus in Panorpidae, is mainly characterized by the
well-developed notal organ on male tergum III. However,
it remains largely unknown how the length of the notal organ influences the nuptial
feeding behaviour of Neopanorpa. Here,
we investigated the nuptial feeding by comparing the morphology of
mating-related structures and the genital coupling of a) Neopanorpa lui Chou
& Ran, 1981 with a weakly-developed notal organ, b) N. carpenteri Cheng, 1957 with a
medium-sized notal organ, and c) N.
longiprocessa Hua & Chou, 1997 with an extremely elongated notal organ.
The couples of N. lui and N. carpenteri maintain an intermittent mouth-to-mouth mode but do
not exchange any edible food. After that the males secrete a salivary mass onto
the surface as a nuptial gift, which is distinctly larger in N. carpenteri than in N. lui.
Correspondingly, the male salivary glands are more developed in N. carpenteri than in N. lui.
Males of N. longiprocessa bear very
short salivary glands corresponding to a coercive mating tactic. The genital couplings
are similar among the three species of Neopanorpa.
The paired hypovalves of males are used to control the cerci of females.
The prominent basal processes of male gonostyli grasp the posterior portion of
the female medigynium across the intersegmental membrane. The male aedeagus
physically couples with the female medigynium to ensure the male phallotreme to
connect to the female copulatory pore. The influence of the notal
organ length on the nuptial feeding behaviour of Neopanorpa is briefly discussed.

description: We have investigated the transport properties of one-dimensional (1D) constrictions defined by split-gates in high quality GaAs/AlGaAs heterostructures. In addition to the usual quantized conductance plateaus, the equilibrium conductance shows a structure close to $0.7(2e^2/h)$, and in consolidating our previous work [K.~J. Thomas et al., Phys. Rev. Lett. 77, 135 (1996)] this 0.7 structure has been investigated in a wide range of samples as a function of temperature, carrier density, in-plane magnetic field $B_{\parallel}$ and source-drain voltage $V_{sd}$. We show that the 0.7 structure is not due to transmission or resonance effects, nor does it arise from the asymmetry of the heterojunction in the growth direction. All the 1D subbands show Zeeman splitting at high $B_{\parallel}$, and in the wide channel limit the $g$-factor is $\mid g \mid \approx 0.4$, close to that of bulk GaAs. As the channel is progressively narrowed we measure an exchange-enhanced $g$-factor. The measurements establish that the 0.7 structure is related to spin, and that electron-electron interactions become important for the last few conducting 1D subbands.

description: We propose a method for spatial downscaling of Landsat 8-derived LST maps from 100(30 m) resolution down to 2–4 m with the use of the Multiple Adaptive Regression Splines (MARS) models coupled with very high resolution auxiliary data derived from hyperspectral aerial imagery and large-scale topographic maps. We applied the method to four Landsat 8 scenes, two collected in summer and two in winter, for three British towns collectively representing a variety of urban form. We used several spectral indices as well as fractional coverage of water and paved surfaces as LST predictors, and applied a novel method for the correction of temporal mismatch between spectral indices derived from aerial and satellite imagery captured at different dates, allowing for the application of the downscaling method for multiple dates without the need for repeating the aerial survey. Our results suggest that the method performed well for the summer dates, achieving RMSE of 1.40–1.83 K prior to and 0.76–1.21 K after correction for residuals. We conclude that the MARS models, by addressing the non-linear relationship of LST at coarse and fine spatial resolutions, can be successfully applied to produce high resolution LST maps suitable for studies of urban thermal environment at local scales.

description: The "metallic" regime of holes in GaAs/AlGaAs heterostructures corresponds to densities where two splitted heavy hole bands exist at a zero magnetic field. Using Landau fan diagrams and weak field magnetoresistance curves we extract the carrier density in each band and the interband scattering rates. The measured inelastic rates depend Arrheniusly on temperature with an activation energy similar to that characterizing the longitudinal resistance. The "metallic" characteristics, namely, the resistance increase with temperature, is hence traced to the activation of inelastic interband scattering. The data are used to extract the bands dispersion relations as well as the two particle-hole excitation continua. It is then argued that acoustic plasmon mediated Coulomb scattering might be responsible for the Arrhenius dependence on temperature. The absence of standard Coulomb scattering characterized by a power law dependence upon temperature is pointed out.

description: The magnetic resonance at 41 meV observed in neutron scattering studies of Y Ba_2 Cu_3 O_7 holds a key position in the understanding of high-T_c superconductivity. Within the SO(5) model for superconductivity and antiferromagnetism, we have calculated the effect of an applied magnetic field on the neutron scattering cross-section of the magnetic resonance. In the presence of vortices, the neutron scattering cross-section shows clear signatures of not only the fluctuations in the superconducting order parameter ψ, but also the modulation of the phase of ψdue to vortices. In reciprocal space we find that i) the scattering amplitude is zero at (pi/a,pi/a), ii) the resonance peak is split into a ring with radius pi/d centered at (pi/a,pi/a), d being the vortex lattice constant, and consequently, iii) the splitting pi/d scales with the magnetic field as sqrt{B}.

description: Floating car data of car-following behavior in cities were compared to existing microsimulation models, after their parameters had been calibrated to the experimental data. With these parameter values, additional simulations have been carried out, e.g. of a moving car which approaches a stopped car. It turned out that, in order to manage such kinds of situations without producing accidents, improved traffic models are needed. Good results have been obtained with the proposed generalized force model.

We highlight the key challenges in capturing sufficiently good data with no tracking devices - starting from sensor selection and accurate 6DoF pose estimation to natural language processing. In particular, we focus on two showcases: gluing task with a glue gun and simple block-stacking with variable blocks. Furthermore, we discuss how a linguistic description of the task could help to improve the accuracy of task description. We also present the whole architecture of our transfer of the imitated task to the simulated and real robot environment.

description: The research work proposes a system which can handle different types of selected words into a common vision-based platform. These sign languages are used not only to communicate with deaf and dumb people but also to exchange ideas with people who can hear but physically cannot speak. Most of the researchers work on the sign language by processing the video with frames in an equal or regular interval. Some of the factors that affect this phenomenon are colour, angle, the position of hand-disturb, dialectical variations of languages etc. All these factors act as impediments to create a perfect sign language system. Region based analysis is used to exploit the interior pixels and boundary of the object. These shape descriptors are more sensible to distortions and noise. The sign language learning is classified into unsupervised and supervised learning. The studies in the realm of sign language can be comprehended as a complicated one and researches are going on in the fields of supervised and unsupervised learning. The research work proposes a system which can handle different types of selected words into a common vision-based platform. Feature extractions like Wavelet transform method can be used in future for better results. Other classifiers like Component Analysis, Support Vector Machine and Linear Discrimination Analysis can also be used for conducting experiments and to improve the recognition rate.

description: We consider the two-dimensional (2D) quantum Heisenberg antiferromagnet at zero temperature with two types of locally frustrating perturbations - an isolated ferromagnetic bond (FMB) and a quantum impurity spin, coupled symmetrically to the two sublattices. An analytic technique is developed to study strong defect-environment interaction. In the case of a FMB we find that, contrary to the previous linear spin-wave result, the local magnetization stays finite even for strong frustration. For an antiferromagnetic coupling of a quantum impurity spin with its environment, we find a local ground state transition. All our calculations are compared with numerical results from exact diagonalization on small clusters.

description: Malicious web domains represent a big threat to web users' privacy and security. With so much freely available data on the Internet about web domains' popularity and performance, this study investigated the performance of well-known machine learning techniques used in conjunction with this type of online data to identify malicious web domains. Two datasets consisting of malware and phishing domains were collected to build and evaluate the machine learning classifiers. Five single classifiers and four ensemble classifiers were applied to distinguish malicious domains from benign ones. In addition, a binary particle swarm optimisation (BPSO) based feature selection method was used to improve the performance of single classifiers. Experimental results show that, based on the web domains' popularity and performance data features, the examined machine learning techniques can accurately identify malicious domains in different ways. Furthermore, the BPSO-based feature selection procedure is shown to be an effective way to improve the performance of classifiers.

Unusual T_c variation with hole concentration in Bi_2Sr_{2-x}La_xCuO_{6+δ}

description: We have investigated the $T_c$ variation with the hole concentration $p$ in the La-doped Bi 2201 system, Bi$_2$Sr$_{2-x}$La$_x$CuO$_{6+δ}$. It is found that the Bi 2201 system does not follow the systematics in $T_c$ and $p$ observed in other high-$T_c$ cuprate superconductors (HTSC's). The $T_c$ vs $p$ characteristics are quite similar to what observed in Zn-doped HTSC's. An exceptionally large residual resistivity component in the inplane resistivity indicates that strong potential scatterers of charge carriers reside in CuO$_2$ planes and are responsible for the unusual $T_c$ variation with $p$, as in the Zn-doped systems. However, contrary to the Zn-doped HTSC's, the strong scatter in the Bi 2201 system is possibly a vacancy in the Cu site.

The Spectral Density of the QCD Dirac Operator and Patterns of Chiral Symmetry Breaking

description: We study the spectrum of the QCD Dirac operator for two colors with fermions in the fundamental representation and for two or more colors with adjoint fermions. For $N_f$ flavors, the chiral flavor symmetry of these theories is spontaneously broken according to $SU(2N_f)\to Sp(2N_f)$ and $SU(N_f)\to O(N_f)$, respectively, rather than the symmetry breaking pattern $SU(N_f) \times SU(N_f) \to SU(N_f)$ for QCD with three or more colors and fundamental fermions. In this paper we study the Dirac spectrum for the first two symmetry breaking patterns. Following previous work for the third case we find the Dirac spectrum in the domain $λ\ll Λ_{\rm QCD}$ by means of partially quenched chiral perturbation theory. In particular, this result allows us to calculate the slope of the Dirac spectrum at $λ= 0$. We also show that for $λ\ll 1/L^2 Λ_{QCD}$ (with $L$ the linear size of the system) the Dirac spectrum is given by a chiral Random Matrix Theory with the symmetries of the Dirac operator.

Homodyne Measurements on a Bose-Einstein Condensate

Year: 1997

description: We investigate a non-destructive measurement technique to monitor Josephson-like oscillations between two spatially separated neutral atom Bose-Einstein condensates. One condensate is placed in an optical cavity, which is strongly driven by a coherent optical field. The cavity output field is monitored using a homodyne detection scheme. The cavity field is well detuned from an atomic resonance, and experiences a dispersive phase shift proportional to the number of atoms in the cavity. The detected current is modulated by the coherent tunneling oscillations of the condensate. Even when there is an equal number of atoms in each well initially, a phase is established by the measurement process and Josephson-like oscillations develop due to measurement back-action noise alone.

Ordering Dynamics of Heisenberg Spins with Torque: Crossover, Spinwaves and Defects
Creators: name: Das, Jayajit
name: Rao, Madan
Publisher: name: arXiv
Year: 2000
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We study the effect of a torque induced by the local molecular field on the phase ordering dynamics of the Heisenberg model when the total magnetization is conserved. The torque drives the zero-temperature ordering dynamics to a new fixed point, characterized by exponents $z=2$ and $λ\approx 5$. This `torque-driven' fixed point is approached at times such that $g^2 t\gg 1$, where $g$ is the strength of the torque. All physical quantities, like the domain size $L(t)$ and the equal and unequal time correlation functions obey a crossover scaling form over the entire range of $g$. An attempt to understand this crossover behavior from the approximate Gaussian Closure Scheme fails completely, implying that the dynamics at late times cannot be understood from the dynamics of defects alone. We provide convincing arguments that the spin configurations can be decomposed in terms of defects and spin-waves which interact with each other even at late times. In the absence of the torque term, the spin waves decay faster, but even so we find that the Gaussian closure scheme is inconsistent. In the latter case the inconsistency may be remedied by including corrections to a simple gaussian distribution. For completeness we include a discussion of the ordering dynamics at $T_c$, where the torque is shown to be relevant, with exponents $z=4-ε/2$ and $λ= d$ (where $ε= 6-d$). We show to all orders in perturbation theory that $λ=d$ as a consequence of the conservation law.

description: This new book in which author tries to show the rational way how to correctly we can estimate the result of investigations or test-control for different statistical information in various sphere of the human activities (engineering, public health, production, investigations on the whole, ecology and to process the statistical data) is depicted many important aspects connected with the statistical information. The point is that all investigations give us many numerical information. For example, about temperature oscillations, pressure or velocity alterations, different travels or accelerations, significances of precisions or reliability, strains or resistance to wear and so on. Usually, several problems will appear in front of the researchers, namely. How many experiments/tests must be done to get the absolutely right results to make the real conclusion? What kind of law of many distributions it is needed to take into account to describe and to process the initial information without any mistakes? Note: the researcher must be a very qualified expert and even a connoisseur in this field because there are more than 30 laws of distribution in mathematics. Moreover, such specialist has to know more than 10 special criteria to use one or maybe two of them to apply in the work during the calculation or the great mistake can be got. All these factors demand to make too many actions, many hours of working and to waste much money. It’s understand that during these actions minimum one (or two) mistake(s) could take place in practice. Consequently, the important conclusion will not be right and the sequels can be even as a tragedy. That’s why such problem must be solved more quickly and by means of the simplest methods which have the maximum reliability and trustworthiness. In this book author is ready to solve this task rather difficult and important to many academics, researchers, persons with higher technical education and to the practical workers. Firstly, some introductory information connected with the traditional methods in the highest mathematic connected with the calculation will be given before the practical examples.

description: This investigation demonstrates a way to innovatively modify the ferritic microstructure at a local scale, particularly at the failure prone area such as Charpy V-notch (CVN) root. Tensile pre-strain (PS) up to 6 percent and 12 percent were employed before annealing (An) the samples at 650°C for 15 minutes. Ferrite grain size increased sharply and gradually (along the distance ahead of the notch root) within the microstructurally modified region in 6-12 percent pre-strained and annealed samples, respectively. Critical strain which promotes strain induced boundary migration (SIBM), was found to be 0.1 which resulted in abnormally coarse ferrite grains.

description: We study the distribution of the complex temperature zeros for the partition function of the Ising model on a Sierpinski gasket using an exact recursive relation. Although the zeros arrange on a curve pinching the real axis at T=0 in the thermodynamic limit, their density vanishes asymptotically along the curve approaching the origin. This phenomenon explains the coincidence of the low temperature regime on the Sierpinski gasket and on the linear chain.
