Oreophryne variabilis

description: Oreophryne variabilis (Boulenger, 1896a)
 Description
 Small adult size, SVL = 16.15 – 27.85 mm; snout rounded; nostrils are located between the eyes and the tip of the snout; tympanum hidden or indistinct, small finger disks; third finger slightly longer than the second and fourth fingers; subarticular tubercles developed, inner metatarsal tubercle an ellipse, heel reaches the posterior eye when adpressed; tibia reaches half of body length when adpressed (TL/SVL = 0.513 – 0.517). Dorsum is yellowish to dark, with scattered black spots, dorsolateral fold from eyes to shoulders.
 Habitat
 This species was often found concealed in leaf litter in the water flows in plots 4 and 5 (primary forest). Individuals were sensitive to light and movement. When approached they quickly entered the water flow to hide among the leaf litter, in grass, or under fallen wood. The species was found active at 21 – 23°C and 86 – 86% humidity.
 Remarks
 This species was previously reported from southwest Sulawesi (Iskandar and Tjan 1996), and is also known from mounts Lompobatang and Latimojong above 1000 m asl in southern Sulawesi, and from Gunung Karua at 1200 m asl in south central Sulawesi (IUCN 2019). The presence of the species in this study is a new record in Lake Kalimpa ’ a and Lore Lindu National Park.

description: A performance prediction method for massively parallel computation is proposed. The method is based on performance modeling and Bayesian inference to predict elapsed time T as a function of the number of used nodes P (T=T(P)). The focus is on extrapolation for larger values of P from the perspective of application researchers. The proposed method has several improvements over the method developed in a previous paper, and application to real-symmetric generalized eigenvalue problem shows promising prediction results. The method is generalizable and applicable to many other computations.

description: We study the macroscopic dynamical properties of fermion and quantum-spin systems with long-range, or mean-field, interactions. The results obtained are far beyond previous ones and require the development of a mathematical framework to accommodate the macroscopic long-range dynamics, which corresponds to an intricate combination of classical and short-range quantum dynamics. In this paper we focus on the classical part of the long-range, or mean-field, macroscopic dynamics, but we already introduce the full framework. The quantum part of the macroscopic dynamics is studied in a subsequent paper. We show that the classical part of the macroscopic dynamics results from self-consistency equations within the (quantum) state space. As is usual, the classical dynamics is driven by Liouville's equation.

description: By a mixture density is meant a density of the form $π_μ(\cdot)=\intπ_θ(\cdot)\timesμ(dθ)$, where $(π_θ)_{θ\inΘ}$ is a family of probability densities and $μ$ is a probability measure on $Θ$. We consider the problem of identifying the unknown part of this model, the mixing distribution $μ$, from a finite sample of independent observations from $π_μ$. Assuming that the mixing distribution has a density function, we wish to estimate this density within appropriate function classes. A general approach is proposed and its scope of application is investigated in the case of discrete distributions. Mixtures of power series distributions are more specifically studied. Standard methods for density estimation, such as kernel estimators, are available in this context, and it has been shown that these methods are rate optimal or almost rate optimal in balls of various smoothness spaces. For instance, these results apply to mixtures of the Poisson distribution parameterized by its mean. Estimators based on orthogonal polynomial sequences have also been proposed and shown to achieve similar rates. The general approach of this paper extends and simplifies such results. For instance, it allows us to prove asymptotic minimax efficiency over certain smoothness classes of the above-mentioned polynomial estimator in the Poisson case. We also study discrete location mixtures, or discrete deconvolution, and mixtures of discrete uniform distributions.

description: This study advanced knowledge regarding dating violence by examining factors related to attitudes towards dating violence as well as the less investigated ability to recognize early warning signs of dating violence using a sample of college women and men. Specifically, this study explored the contributions of expressivity and instrumentality as well as hyperfemininity and hypermasculinity in predicting college students’ attitudes toward dating violence and their ability to recognize risk of dating abuse after controlling for prior education about and experience with dating violence. Four hundred and thirty-three heterosexual, unmarried, undergraduate women and 108 heterosexual, unmarried, undergraduate men between the ages of 18 and 22 completed the study. For women, hyperfemininity was associated with less acceptance of dating violence and better risk recognition. For men, hypermasculinity was the strongest predictor of acceptance of dating violence and inability to recognize warning signs of dating violence. These findings can be used to inform future interventions to reduce dating violence among college students.

 Description
 Adult males, SVL 44.90 mm; head width (HW/SVL = 0.324) and head length (HL/ SVL = 0.364, HL/HW = 1.12); nostrils are closer to the tip of the snout than to the eyes, internarial distance equal to distance from the nostrils to the eyes (EN/IN = 1.222, EN/ SVL = 0.098, IN/SVL = 0.080); loreal region concave; snout long (snout/SVL = 0.164); large eyes (EY/SVL = 0.126); tympanum round, distinct (TY/EY = 0.611, TY/SVL = 0.076); vomerine teeth present; there is a distinct fold from behind the eyes above the tympanum to the back arm. The formula for the web of the toe, I 0 – 1 II 0 – 1 III 1 / 2 – 1 IV 1 – 0 V, follows that used by Savage and Heyer (1997); length of tibia, ratio of TL/SVL about 0.537; length of toe (longest to shortest) 4> 5> 3> 2> 1, fourth toe length (T4) with ratio of T4/ SVL about 0.414 and fourth toe disc diameter (T4D) with ratio of T4D/SVL about 0.030; subarticular tubercles developed; inner metatarsal oval; outer metatarsal is very small. The dorsal and ventral surfaces are granularious; dorsal yellowish brown, there is a tint like a thick line between the eyes, and down to the dorsal bottom.
 Habitat
 Some individuals were found hopping among Cuphea carthagenensis plants or sitting and vocalising among partially submerged Axonopus compressus plants. Other individuals were found on the wall of a building. Specimens were collected up to 9 m from the pond and vertically up to 1 m. When approached, individuals of this species immediately jumped into the water or moved into plants in the water. They were found to be active at 19 – 23°C and 84 – 97% humidity.
 Remarks
Distributional data for this species are still lacking. Riyanto et al. (2011) reported that this species was found in Desa Tomado, Sulawesi Tengah, at an elevation of 1008 m asl. In this study, however, it was found at an elevation of 1650 m asl in the open area (plot 7).

Gravitational Instability of Shocked Interstellar Gas Layers

Year: 2008

description: In this paper we investigate gravitational instability of shocked gas layers using linear analysis. An unperturbed state is a self-gravitating isothermal layer which grows with time by the accretion of gas through shock fronts due to a cloud-cloud collision. Since the unperturbed state is not static, and cannot be described by a self-similar solution, we numerically solved the perturbation equations and directly integrated them over time. We took account of the distribution of physical quantities across the thickness. Linearized Rankine-Hugoniot relations were imposed at shock fronts as boundary conditions. The following results are found from our unsteady linear analysis: the perturbation initially evolves in oscillatory mode, and begins to grow at a certain epoch. The wavenumber of the fastest growing mode is given by $k=2\sqrt{2πGρ_\mathrm{E} {\cal M\mit}}/c_\mathrm{s}$, where $ρ_\mathrm{E}, c_\mathrm{s}$ and $\cal M\mit$ are the density of parent clouds, the sound velocity and the Mach number of the collision velocity, respectively. For this mode, the transition epoch from oscillatory to growing mode is given by $t_g = 1.2/\sqrt{2πGρ_\mathrm{E} {\cal M\mit}}$. The epoch at which the fastest growing mode becomes non-linear is given by $2.4δ_0^{-0.1}/\sqrt{2πG ρ_\mathrm{E}{\cal M\mit}}$, where $δ_0$ is the initial amplitude of the perturbation of the column density. As an application of our linear analysis, we investigate criteria for collision-induced fragmentation. Collision-induced fragmentation will occur only when parent clouds are cold, or $α_0=5c_\mathrm{s}^2 R/2G M < 1$, where $R$ and $M$ are the radius and the mass of parent clouds, respectively.

description: Optical manipulation has attracted remarkable interest owing to its versatile and non-invasive nature. However, conventional optical trapping remains inefficient for the nanoscopic world. The emergence of plasmonics in recent years has brought a revolutionary change in overcoming limitations due to diffraction and the requirements for high trapping laser powers. Among the near-field optical trapping cavity-based systems, Fano resonant optical tweezers have a robust trapping capability. In this work, we experimentally demonstrate sequential trapping of 20 nm particles through the use of metamaterial plasmonic optical tweezers. We investigate the multiple trapping via trap stiffness measurements for various trapping positions at low and high incident laser intensities. Our configuration could be used as a light-driven nanoscale sorting device under low laser excitation. Our results provide an alternative approach to trap multiple nanoparticles at distinct hotspots, enabling new ways to control mass transport on the nanoscale.

Revisiting the Black Hole Masses of Soft X-ray-Selected Active Galactic Nuclei

description: In our previous work, using luminosity and the H-beta FWHM as surrogates for black hole mass (M_BH), we compared the black hole masses of narrow-line Seyfert 1 galaxies (NLS1s) and broad-line Seyfert 1 galaxies (BLS1s) in a sample of soft X-ray-selected active galactic nuclei. We found that the distributions of black hole masses in the two populations are statistically different. Recent work shows that the second moment of the H-beta emission line (the line dispersion) is a better estimator of black hole mass than FWHM. To test whether changing the width measure affects our results, we calculate line dispersion-based black hole masses for our sample. We find that using the line dispersion rather than the FWHM as a measure of the gas velocity shifts NLS1 and BLS1 virial product distributions closer together, but they remain distinct. On the M_BH-sigma plane, we find that using the line dispersion leaves NLS1s below the M_BH-sigma relation, but to a less significant degree than when FWHM is used to calculate black hole masses (the [OIII] 5007A FWHM is used as a surrogate for the bulge stellar velocity dispersion). The level of significance of our findings is such that we cannot draw firm conclusions on the location of the two samples on the M_BH-sigma plane. We are still left with two alternative scenarios: either (1) NLS1s lie below the M_BH-sigma relation indicating that their black hole masses are growing, or (2) NLS1s lie on the M_BH-sigma relation, so they preferentially reside in smaller mass, less luminous galaxies; the present data do not allow us to choose one over the other. More trustworthy stellar velocity dispersions and accurate black hole mass measurements are required for a firmer statement about the locus of NLS1s on the M_BH-sigma plane.

description: Solar power generation deployment is increasing globally with photovoltaic modules.  Most energy available to conventional PV is absorbed as heat or passes through.  Performance of Photovoltaic Thermal (PVT) collectors which mimic currently available, polycrystalline, commercial PV modules was measured in the mid-Atlantic US.  A linear model is developed for their performance which uses values available in Typical Meteorological Year files and shows daily accuracies to within 11%.  Pressure losses for the collectors were measured and an empirical model established.  Electrical generation is modeled by PVT in conjunction with an Organic Rankine Cycle.  20% - 45% boosts to electricity production in the Southwest are projected.  5%-15% boosts are projected in the mid-Atlantic.
Suppression of wind-induced torsional instability using partitioned nutation dampers
Creators: name: Lim, Seng Boh
Publisher: name: University of British Columbia
Year: 2009

description: The thesis aims at the development of partitioned rectangular and toroidal dampers for suppressing wind-induced instabilities in torsion of bluff bodies like bridge-decks and bundles of transmission line conductors. To begin with, energy dissipation of the dampers as affected by the system frequency and liquid height, in the presence of partitioning, is assessed. This is followed by a qualitative flow visualization study of the surface waves to provide better appreciation of the dissipation mechanism. Finally, a set of wind tunnel tests with a square prism is undertaken to determine the effectiveness of the dampers in suppressing torsional galloping instability. Results suggest that the optimum partitioning corresponds to the compartment length to width ratio of 1.2 for the rectangular damper, while for the double toroid, it represents the diameter ratios of 1.125 and 2 for the outer and inner rings, respectively. In general, for the rectangular damper, roll motion led to a higher damping compared to the pitch degree of freedom. From flow visualization, it appeared that wave breaking as well as collision of waves promote energy dissipation. During the wind tunnel tests, both rectangular and toroidal dampers proved to be quite successful in suppressing galloping instability in torsion. The information can be used to advantage in the design of bridgedecks and high voltage transmission lines, which are often susceptible to this form of instability.

description: The ARCADE 2 balloon bolometer along with a number of other instruments have detected what appears to be a radio synchrotron background at frequencies below about 3 GHz. Neither extragalactic radio sources nor diffuse Galactic emission can currently account for this finding. We use the locally measured Cosmic ray electron population, demodulated for effects of the Solar wind, and other observational constraints combined with a turbulent magnetic field model to predict the radio synchrotron emission for the Local Bubble. We find that the spectral index of the modelled radio emission is roughly consistent with the radio background. Our model can approximately reproduce the observed antenna temperatures for a mean magnetic field strength B between 3-5 nT. We argue that this would not violate observational constraints from pulsar measurements. However, the curvature in the predicted spectrum would mean that other, so far unknown sources would have to contribute below 100 MHz. Also, the magnetic energy density would then dominate over thermal and cosmic ray electron energy density, likely causing an inverse magnetic cascade with large variations of the radio emission in different sky directions as well as high polarisation. We argue that this disagrees with several observations and thus that the magnetic field is probably much lower, quite possibly limited by equipartition with the energy density in relativistic or thermal particles (B = 0.2-0.6 nT). In the latter case, we predict a contribution of the Local Bubble to the unexplained radio background at most at the per cent level.

description: The ability to design synthesis processes that are out of equilibrium has opened the possibility of creating nanomaterials with remarkable physico-chemical properties, choosing from a much richer palette of possible atomic architectures compared to equilibrium processes in extended systems. In this work, we employ atomistic simulations to demonstrate how to control polymorph selection via cooling rate during nanoparticle freezing in the case of Ni$_3$Al, a material with a rich structural landscape. State-of-the-art free-energy calculations allow to rationalize the complex nucleation process, discovering a switch between two kinetic pathways, yielding the equilibrium structure at room temperature and an alternative metastable one at higher temperature. Our findings address the key challenge in the synthesis of nano-alloys for technological applications, i.e., rationally exploiting the competition between kinetics and thermodynamics by designing a treatment history that forces the system into desirable metastable states.

description: A holographic description of chiral symmetry breaking in the pattern of QCD is reviewed. D7 brane probes are used to include quark fields in a simple non-supersymmetric deformation of the AdS/CFT Correspondence. The axial symmetry breaking is realized geometrically and the quark condensate and meson masses are computable. Surprisingly, treating the model as a description of QCD works quantitatively at the 15% level. Models of this AdS/QCD type typically have a strongly coupled, conformal UV regime that is far from QCD. To systematically move closer to QCD, we propose cutting out the large radius gravitational description and matching operators and couplings at a finite UV cut off in the spirit of a perfect lattice action. A simple example is discussed.

description: A two-wheeled mobile robot, namely Kian-I, is designed and prototyped in this research. The Kian-I is comparable with Khepera-IV in terms of dimensional specifications, mounted sensors, and performance capabilities and can be used for educational purposes and cost-effective experimental tests. A motion control architecture is designed for Kian-I in this study to facilitate accurate navigation for the robot in an immersive environment. The implemented control structure consists of two main components of the path recommender system and trajectory tracking controller. Given partial knowledge about the operation field, the path recommender system adopts B-spline curves and Particle Swarm Optimization (PSO) algorithm to determine a collision-free path curve with translational velocity constraint. The provided optimal reference path feeds into the trajectory tracking controller enabling Kian-I to navigate autonomously in the operating field. The trajectory tracking module eliminate the error between the desired path and the followed trajectory through controlling the wheels' velocity. To assess the feasibility of the proposed control architecture, the performance of Kian-I robot in autonomous navigation from any arbitrary initial pose to a target of interest is evaluated through numerous simulation and experimental studies. The experimental results demonstrate the functional capacities and performance of the prototyped robot to be used as a benchmark for investigation and verification of various mobile robot algorithms in the laboratory environment.

description: Let $\Z_n[i]$ be the ring of Gaussian integers modulo a positive integer $n$. Very recently, Camarero and Martínez [IEEE Trans. Inform. Theory, {\bf 62} (2016), 1183--1192], showed that for every prime number $p>5$ such that $p\equiv \pm 5 \pmod{12}$, the Cayley graph $\mathcal{G}_p=\textnormal{Cay}(\Z_p[i], S_2)$, where $S_2$ is the set of units of $\Z_p[i]$, induces a 2-quasi-perfect Lee code over $\Z_p^m$, where $m=2\lfloor \frac{p}{4}\rfloor$. They also conjectured that $\mathcal{G}_p$ is a Ramanujan graph for every prime $p$ such that $p\equiv 3 \pmod{4}$. In this paper, we solve this conjecture. Our main tools are Deligne's bound from 1977 for estimating a particular kind of trigonometric sum and a result of Lovász from 1975 (or of Babai from 1979) which gives the eigenvalues of Cayley graphs of finite Abelian groups. Our proof techniques may motivate more work in the interactions between spectral graph theory, character theory, and coding theory, and may provide new ideas towards the famous Golomb--Welch conjecture on the existence of perfect Lee codes.

description: We performed muon spin rotation/relaxation measurements to investigate the magnetic behavior of $T^{\prime}$-type Eu$_2$CuO$_4$ (ECO), which is the parent compound of electron-doped cuprate superconductors, and the effects of oxygen-reduction annealing on its magnetism. In as-sintered (AS) ECO, we clarified the development of magnetic correlations upon cooling below $T_\mathrm{N1}$ (= 265 K) as well as the coexistence of a dominant fluctuating spin state and partially ordered spin state in the temperature range between $\sim$150 K and $T_\mathrm{N1}$. Upon further cooling, uniform long-range magnetic order was observed below $T_\mathrm{N2} = 110$ K, which is close to the ordering temperature of 115 K in $T^{\prime}$-type La$_2$CuO$_4$ (LCO) [Phys. Rev. B {\bf 82}, 180508(R) (2010)]. For oxygen-reduction-annealed ECO, a similar ordering sequence with the same $T_\mathrm{N2}$ was observed but without the partially ordered spin state. Therefore, the fluctuating spin state over a wide temperature range and a $T_\mathrm{N2}$ less than the N{é}el temperature ($T_\mathrm{N2} \approx T_\mathrm{N1}$) in $T$-type LCO are common features of the $T^{\prime}$-type parent $R_2$CuO$_4$ ($R$CO, $R$: rare-earth ion). The origin of the partially ordered spin state in AS ECO is discussed from the viewpoint of chemical defect. Furthermore, we discuss the roles of electron doping and repairing defect in the observed effect of annealing on the magnetism of $T^{\prime}$-type $R$CO.

Remarks. The occurrence of B. hydroides in Singapore is known from only four specimens.The first was documented by Dennys (1880a) and Blanford (1881) from a specimen at the Raffles Museum, but they did not provide an account of the species. Smedley (1931) described a specimen at the Raffles Museum of “unknown origin” that may likely be the specimen examined by Blanford (1881). The next report came 89 years later (Table 2) when Gyi (1970) examined MCZ R-8984 and MCZ R-18392. Gyi (1970) provided the locality “Nee Soon Jungle”, but inspection of the MCZ catalogue reveals that the locality for both specimens is unknown. Being that B. hydroides inhabits river mouths and coastal areas (Murphy 2007), Nee Soon as a locale is credible given that Sungei Seletar once reached the present location of Upper Seletar Reservoir, and the area around Springleaf Forest and edges of NSSF appeared to be mangrove forest (Yee et al. 2011). The final specimen is ZMO K2373 which was collected in 1898. If B. hydroides still occurs in Singapore, we presume SBWR and MMMNP may provide the most suitable locations with their extensive mudflats.

description: Online community moderators are on the front lines of combating problems like hate speech and harassment, but new modes of interaction can introduce unexpected challenges. In this paper, we consider moderation practices and challenges in the context of real-time, voice-based communication through 25 in-depth interviews with moderators on Discord. Our findings suggest that the affordances of voice-based online communities change what it means to moderate content and interactions. Not only are there new ways to break rules that moderators of text-based communities find unfamiliar, such as disruptive noise and voice raiding, but acquiring evidence of rule-breaking behaviors is also more difficult due to the ephemerality of real-time voice. While moderators have developed new moderation strategies, these strategies are limited and often based on hearsay and first impressions, resulting in problems ranging from unsuccessful moderation to false accusations. Based on these findings, we discuss how voice communication complicates current understandings and assumptions about moderation, and outline ways that platform designers and administrators can design technology to facilitate moderation.

description: Prostitution is one of the root causes of sex trafficking and the transmission of sexual diseases. The rules and regulations followed by the Indian government to regulate the same, fall under the umbrella of the abolitionism model. Neo-abolitionism (also known as the Nordic model) is a new legislative model that has been introduced by the Nordic countries to regulate prostitution. The purpose of this research paper is to examine the possible effects of the application of the Nordic model on the crime rates and the spread of sexually transmitted diseases in India. Further, we also aim to study the effects of the implementation of Neo-abolitionism in Sweden.

description: We study the macroscopic dynamics of fermion and quantum-spin systems with long-range, or mean-field, interactions, which turns out to be equivalent to an intricate combination of classical and short-range quantum dynamics. In this paper we focus on the \emph{quantum} part of the long-range macroscopic dynamics. The classical part is studied in a companion paper. Altogether, the results obtained are far beyond previous ones and required the development of a suitable mathematical framework. The entanglement of classical and quantum worlds is noteworthy, opening new theoretical perspectives, and is shown here to be a consequence of the highly non-local character of long-range, or mean-field, interactions.

 Description
 SVL = 33.05 – 43.40 mm; vomerine teeth present; a slightly pointed snout; loreal region slightly concave; nostrils are located in the middle between the tip of the snout and the eyes; internarial as wide as the upper eyelid; tympanum moderately distinct, 1 / 3 to 1 / 2 (TY/ EY = 0.363 – 0.427) of the eye diameter. The length of all finger disks is almost the same as or slightly larger than the tympanum; outer fingers are 2 / 3 webbed; penultimate phalanx of the fourth toe is free of webbing; subarticular tubercles and inner metatarsals are small; the heel reaches the anterior eyes or nostril when adpressed; tibia length 1 / 2 of body length when adpressed (TL/SVL = 0.506 – 0.555). Dorsal surface is reddish brown with black spots spread irregularly on the body and limbs; ventral surface is white or yellowish, granularious; there is a black line on the lateral side that separates the base colour on the dorsum and venter.
 Habitat
 This species is mainly arboreal and was observed in the canopy and sub-canopy and rarely found on the soil surface. The specimens were collected from Curculigo sp. leaves and Diplazium sp. branches 0.5 – 1.5 m above the water surface and 0.1 – 3 m away from the water flow. It was found to be active at 19 – 22°C and 73 – 92% humidity.
 Remarks
 This species is known only from southwestern and central Sulawesi, found above 1000 m asl (Iskandar and Mumpuni 2004). In the area of Lake Kalimpa ’ a, this species was found in plots 1 and 4 in the primary forest at elevations from 1668 – 1673 m asl. This species was less sensitive to our approach and often remained stationary when inadvertently touched.

description: In magnetic films driven by spin-polarized currents, the perpendicular-to-plane anisotropy is equivalent to breaking the time translation symmetry, i.e., to a parametric pumping. In this work, we numerically study those current-driven magnets via the Landau-Lifshitz-Gilbert-Slonczewski equation in one spatial dimension. We consider a space-dependent anisotropy field in the parametric-like regime. The anisotropy profile is antisymmetric to the middle point of the system. We find several dissipative states and dynamical behavior and focus on localized patterns that undergo oscillatory and phase instabilities. Using numerical simulations, we characterize the localized states' bifurcations and present the corresponding diagram of phases.

The Velocity Field of Quasar Broad Emission Line Gas

Subjects: subject: Astrophysics (astro-ph)

description: In this Letter, the broad emission line (BEL) profiles of superluminal quasars with apparent jet velocities, $β_{a}>10$, (ultraluminal QSOs, or ULQSOs hereafter) are studied as a diagnostic of the velocity field of the BEL emitting gas in quasars. The ULQSOs are useful because they satisfy a very strict kinematical constraint, their parsec scale jets must be propagating within $12^{\circ}$ of the line of sight. We know the orientation of these objects with great certainty. The large BEL FWHM, $\sim 3,000 \mathrm{km/s} - 6,000 \mathrm{km/s}$, in ULQSOs tend to indicate that the BEL gas has a larger component of axial velocity (either random or in a wind) along the jet direction than previously thought.

Empirical prediction and auralization of noise levels and reverberation times in industrial workrooms
Creators: name: Heerema, Nelson Raymond
Publisher: name: University of British Columbia
Year: 2009

description: Cost-effective noise control in industrial workrooms may be achieved by predicting and auralizing the soundfields generated by sources (e.g. equipment and fans) in the presence of candidate acoustical treatments. Prediction techniques available to noise-control practitioners range from computationally intensive but accurate ray-tracing and method-of-images models to simpler, but less accurate, models based on diffuse-field theory and empirical models. The auralization of industrial noise may be useful in demonstrating its negative effects. Auralization (acoustical virtual reality) systems range from cheap but grossly inaccurate stereo systems to very expensive but accurate digital-signal-processing engines. A combined noise prediction and auralization system for industrial workrooms - PlantNoise" - that bridges this cost-performance gap is presented here. New empirical noise-level and reverberation time prediction algorithms based on measured sound propagation curves and reverberation times are developed. Prediction accuracies approach those of the more complex models while calculation times are negligible. Auralization of the predicted noise levels is effected on an IBM-compatible PC equipped with a soundcard and headphones. Pink noise is generated at the same sound pressure level and frequency content as the predicted levels (in octave bands from 125 Hz to 4 kHz), and then presented to the system user over the headphones. The user experiences the predicted soundfield (updated in real-time) during a computer 'walk-through' of the virtual workroom. A graphical user interface enables visualization of the workroom floor plan, including sound sources and user position. Predicted octave-band reverberation times and noise levels are displayed on the screen. The total noise level at the user position is also displayed in dB or dBA. A contour map of the total noise levels is displayed on the workroom floor plan at the user's request.

description: By the Pauli exclusion principle no quantum state can be occupied by more than one electron. One can put it as a constraint on the electron density matrix that bounds its eigenvalues by 1. Shortly after its discovery the Pauli principle has been replaced by skew symmetry of a multi-electron wave function. In this paper we solve a longstanding problem about the impact of this replacement on the electron density matrix, that goes far beyond the original Pauli principle.

Photometric Selection of QSO Candidates From GALEX Sources

Year: 2006

description: We present a catalog of 36,120 QSO candidates from the Galaxy Evolution Explorer (GALEX) Release Two (GR2) UV catalog and the USNO-A2.0 optical catalog. The selection criteria are established using known quasars from the Sloan Digital Sky Survey (SDSS). The SDSS sample is then used to assign individual probabilities to our GALEX-USNO candidates. The mean probability is ~50%, and would rise to ~65% if better morphological information than that from USNO were available to eliminate galaxies. The sample is ~40% complete for i<=19.1. Candidates are cross-identified in 2MASS, FIRST, SDSS, and XMM-Newton Slewing Survey (XMMSL1), whenever such counterparts exist. The present catalog covers the 8000 square degrees of GR2 lying above 25 degrees Galactic latitude, but can be extended to all 24,000 square degress that satisfy this criterion as new GALEX data become available.

Topological Hall effect and the magnetic states of Nowotney chimney ladder compound Cr$_{11}$Ge$_{19}$}

description: We have investigated the magnetic and charge transport properties of single crystals of Nowotney Chimney Ladder compound Cr$_{11}$Ge$_{19}$ and mapped out a comprehensive phase diagram reflecting the complicated interplay between the Dzyaloshinskii-Moriya (DM) interaction, the dipolar interaction, and the magnetic anisotropy. We have identified a set of interesting magnetic phases and attributed a finite topological Hall effect to the recently discovered bi-skyrmion phase. These data also suggest the existence of an anti-skyrmion state at finite fields for temperatures just below the magnetic ordering temperature, $T_c$, as indicated by a distinct change in sign of the topological Hall effect. Above $T_c$, we discovered a region of enhanced magnetic response corresponding to a disordered phase likely existing near the ferromagnetic critical point under small magnetic fields. Strong spin chirality fluctuations are demonstrated by the large value of the topological Hall resistivity persisting up to 1 T which is most likely due to the existence of the DM interaction. We argue that changes to the topological Hall effect correspond to different topological spin textures that are controlled by magnetic dipolar and DM interactions that vary in importance with temperature.
