The Structure and Environment of Young Stellar Clusters in Spiral Galaxies
Creators: name: Larsen, Soeren S.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A search for stellar clusters has been carried out in 18 nearby spiral galaxies, using HST/WFPC2 archive images. All of the galaxies have previously been imaged from the ground in UBVI. A catalogue of structural parameters, photometry and comments based on visual inspection of the clusters is compiled and used to investigate correlations between cluster structure, environment, age and mass. Least-squares fits to the data suggest correlations between both the FWHM and half-light radius (Reff) of the clusters and their masses (M) at about the 3-sigma level. Although both relations show a large scatter, the fits have substantially shallower slopes than for a constant-density relation. However, many of the youngest clusters have extended halos which make the Reff determinations uncertain. There is no evidence for galaxy-to-galaxy variations in the mean cluster sizes. In particular, the mean sizes do not appear to depend on the host galaxy star formation rate surface density. Many of the youngest objects (age < 10 Myr) are located in strongly crowded regions, and about 1/3-1/2 of them are double or multiple sources. The HST images are also used to check the nature of cluster candidates identified in a previous ground-based survey. The contamination rate in the ground-based sample is generally less than about 20%, but some cluster identifications remain ambiguous because of crowding even with HST imaging, especially for the youngest objects.

description: Fully 3D cosmological simulations of scalar field dark matter with self-interactions, also known as Bose-Einstein condensate dark matter, are performed using a set of effective hydrodynamic equations. These are derived from the non-linear Schrödinger equation by performing a smoothing operation over scales larger than the de Broglie wavelength, but smaller than the self-interaction Jeans' length. The dynamics on the de Broglie scale become an effective thermal energy in the hydrodynamic approximation, which is assumed to be subdominant in the initial conditions, but become important as structures collapse and the fluid is shock-heated. The halos that form have Navarro-Frenk-White envelopes, while the centers become cored due to the fluid pressures (thermal + self-interaction). The core radii are mostly determined by the self-interaction Jeans' length, even though the effective thermal energy eventually dominates over the self-interaction energy everywhere, a result that is insensitive to the initial smallness of the thermal energy. Scaling relations for the simulated population of halos are compared with Milky Way dwarf spheroidals and nearby galaxies, assuming a Burkert halo profile, and are found to not match, also for core radii $R_c\approx 1\text{kpc}$, which has generally been the value expected to resolve the cusp-core issue. However, the simulations have a limited volume, and therefore a limited halo mass range, include no baryonic physics, and use fiducial cold dark matter initial conditions with a cut-off near the Jeans' length at $z=50$, all of which can affect the halo properties.

description: We show how two techniques from statistical physics can be adapted to solve a variant of the notorious Unique Games problem, potentially opening new avenues towards the Unique Games Conjecture. The variant, which we call Count Unique Games, is a promise problem in which the "yes" case guarantees a certain number of highly satisfiable assignments to the Unique Games instance. In the standard Unique Games problem, the "yes" case only guarantees at least one such assignment. We exhibit efficient algorithms for Count Unique Games based on approximating a suitable partition function for the Unique Games instance via (i) a zero-free region and polynomial interpolation, and (ii) the cluster expansion. We also show that a modest improvement to the parameters for which we give results would refute the Unique Games Conjecture.

description: The external environment confronting both farmers and policymakers obviously has changed dramatically over the past 3 years. Grain surpluses in the hands of the government have disappeared~ drought has cut crop production in several important areas, and the news media have rediscovered the fact that a high proportion of the world's population subsists on diets which even in good crop years are-only marginally adequate. In the U, S., food prices, and especially the prices of grains, have risen to levels thought highly improbable only 3 or 4 years ago. Does the new environment call for equally dramatic shifts in policy? This is the question I have been asked to discuss.

description: Let F be a codimension one singular holomorphic foliation on a compact complex manifold M. Assume that there exists a meromorphic vector field X on M generically transversal to F. Then, we prove that F is the meromorphic pull-back of an algebraic foliation on an algebraic manifold N, or F is transversely projective outside a compact hypersurface, improving our previous work (see version 1). Such a vector field insures the existence of a global meromorphic Godbillon-Vey sequence for the foliation F. We derive sufficient conditions on this sequence insuring such alternative. For instance, if there exists a finite Godbillon-Vey sequence or if the Godbillon-Vey invariant is zero, then either F is the pull-back of a foliation on a surface, or F is transversely projective. We illustrate these results with many examples.
description: A part of version 1 will appear in Comment. Math. Helv. 81 (2006), namely the main theorem which actually did not need use of Godbillon-Vey sequences ; this was observed by E. Ghys. In this new version, we weaken assumptions for the main theorem and really use Godbillon-Vey sequences to prove it. Auxiliary results are left unchanged

Mathematical modelling of transport phenomena in compressible multicomponent flows

description: The present article proposes a diffuse interface model for compressible multicomponent flows with transport phenomena of mass, momentum and energy (i.e., mass diffusion, viscous dissipation and heat conduction). The model is reduced from the seven-equation Baer-Nuziato type model with asymptotic analysis in the limit of instantaneous mechanical relaxations. The main difference between the present model and the Kapila's five-equation model consists in that different time scales for pressure and velocity relaxations are assumed, the former being much smaller than the latter. Thanks to this assumption, the velocity disequilibrium is retained to model the mass diffusion process. Aided by the diffusion laws, the final model still formally consists of five equations. The proposed model satisfy two desirable properties : (1) it respects the laws of thermodynamics, (2) it is free of the spurious oscillation problem in the vicinity of the diffused interface zone. The mass diffusion, viscous dissipation and heat conduction processes contribute parabolic partial differential equations that are solved with the Chebyshev method of local iterations. Numerical results show that the proposed model maintains pressure, velocity and temperature equilibrium near the diffused interface. Convergence tests demonstrate that the numerical methods achieve second order in space and time. The proposed model and numerical methods are applied to simulate the laser-driven RM instability problem in inertial confinement fusion, good agreement with experimental results are observed.

description: The electromagnetic and axial form factors of the nucleon and its lowest positive parity excitations, the Delta(1232) and the N*(1440), are calculated with constituent-quark models that are specified by simple algebraic representations of the mass-operator eigenstates. Poincaré covariant current operators are generated by the dynamics from single-quark currents that are covariant under a kinematic subgroup. The dependence of the calculated form factors on the choice of kinematics and on the gross features of the wave functions is illustrated for instant-form, point-form, and front-form kinematics. A simple algebraic form of the orbital ground state wave function, which depends on two parameters, allows a fair description of all the form factors over the empirically accessible range, although with widely different choices of the parameters, which determine the range and shape of the orbital wave function. The neutron electric form factor requires additional features, for instance the presence of mixed symmetry S-state component with 1 -- 2 % probability in the ground state wave function. Instant and front form kinematics demand a spatially extended wave function, whereas in point form kinematics the form factors may be described with a quite compact wave function.

description: The objective of Project Blue Sky was to mobilize Olympic and Paralympic athletes to take a leadership role and to use the Vancouver 2010 Olympic and Paralympic Winter Games to shine a spotlight on climate change. To achieve this goal, spokespeople were identified, partnerships were formed, social media was activated, blog seeding was planned, and different media outlets were approached. The website attracted environmentally, socially, and health conscious individuals because of its innovative and original concept. A website needs to be flexible and go through many iterations before it’s complete. Unfortunately, many of the changes that were applied to the Project Blue Sky website were not done early enough in order to make a substantial difference towards its 1 billion kilometre goal. This report will discuss the methods that Project Blue Sky used to attract members to the website and will also discuss what the barriers to engagement were. In addition, this report will discuss how the website started, who was involved in the project and what the Project Blue Sky team learned throughout the project. The team at Project Blue Sky hopes this report will serve as a tool for future community engagement projects. According to a report from the David Suzuki Foundation, “(public engagement) is the category where VANOC (has) had the least success”i. As such, this report aims to understand how engagement, or lack there of, contributed to the limited success of this project and will offer recommendations for future projects. The recommendations found throughout this report are summarized in Appendix 1.

description: We analyze fermionic response of strongly correlated holographic matter in presence of inhomogeneous periodically modulated potential mimicking the crystal lattice. The modulation is sourced by a scalar operator that explicitly breaks the translational symmetry in one direction. We compute the fermion spectral function and show that it either exhibits a well defined Fermi surface with umklapp gaps opening on the Brillouin zone boundary at small lattice wave vector, or, when the wave vector is large, the Fermi surface is anisotropically deformed and the quasiparticles get significantly broadened in the direction of translation symmetry breaking. Making use of the ability of our model to smoothly extrapolate to the homogeneous Q-lattice like setup, we show that this novel effect is not due to the periodic modulation of the potential and Umklapp physics, but rather due to the anisotropic features of the holographic horizon. That means it encodes novel physics of strongly correlated critical systems which may be relevant for phenomenology of exotic states of electron matter.

description: Stress is one of the main issues of nowadays lifestyle. If it becomes chronic it can have adverse effects on the human body. Thus, the early detection of stress is crucial to prevent its hurting effects on the human body and have a healthier life. Stress can be assessed using physiological signals. To this end, Photoplethysmography (PPG) is one of the most favorable physiological signals for stress assessment. This research is focused on developing a novel technique to assess stressful events using raw PPG signals recorded by Empatica E4 sensor. To achieve this goal, an adaptive convolutional neural network (CNN) combined with Multilayer Perceptron (MLP) has been utilized to realize the detection of stressful events. This research will use a dataset that is publicly available and named wearable stress and effect detection (WESAD). This dataset will be used to simulate the proposed model and to examine the advantages of the proposed developed model. The proposed model in this research will be able to distinguish between normal events and stressful events. This model will be able to detect stressful events with an accuracy of 96.7%.

description: Proportional electroluminescence (EL) in noble gases is used in two-phase detectors for dark matter search to record ionization signals in the gas phase induced by particle scattering in the liquid phase (S2 signals). In this work, the EL pulse-shapes in a two-phase argon detector have for the first time been studied systematically in a wide range of reduced electric field, varying from 3 to 9 Td. The pulse-shapes were studied at different readout configurations and spectral ranges: using cryogenic PMTs and SiPMs, with and without a wavelength shifter (WLS), in the VUV and visible range. We observed the fast component and two unusual slow components, with time constants of about 5 $μ$s and 40 $μ$s. The unusual characteristic property of slow components was that their contribution and time constants increased with electric field.

Then, using translations, we introduce the invariant vector fields. Finally, the definition of Lie bracket realized by Dubois--Violette, considering elements in the center of the algebra, is also extended to these invariant vector fields.

description: The purpose of this paper is to call attention to the important role that the statistical model and the data source play in the determination of a numerical estimate of price response. Price "elasticities" are estimated from both time-series and cross-sectional viewpoints using the same data base and essentially the same method of estimation, ordinary least squares regression (OLS). In each case the data are organized in a slightly different manner. The results obtained are reasonable from a statistical point of view, and yet each set suggests vastly different policy implications.

description: Supernova blasts envelop many surrounding stellar systems, transferring kinetic energy to small bodies in the systems. Geologic evidence from $^{60}\rm Fe$ points to recent nearby supernova activity within the past several Myr. Here, we model the transfer of energy and resulting orbital changes from these supernova blasts to the Oort Cloud, the Kuiper belt, and Saturn's Phoebe ring. For the Oort Cloud, an impulse approximation shows that a 50 pc supernova can eject approximately half of all objects less than 1 cm while altering the trajectories of larger ones, depending on their orbital parameters. For stars closest to supernovae, objects up to $\sim$100 m can be ejected. Turning to the explored solar system, we find that supernovae closer than 50 pc may affect Saturn's Phoebe ring and can sweep away Kuiper belt dust. It is also possible that the passage of the solar system through a dense interstellar cloud could have a similar effect; a numerical trajectory simulation shows that the location of the dust grains and the direction of the wind (from a supernova or interstellar cloud) has a significant impact on whether or not the grains will become unbound from their orbit in the Kuiper belt. Overall, nearby supernovae sweep micron-sized dust from the solar system, though whether the grains are ultimately cast towards the Sun or altogether ejected depends on various factors. Evidence of supernova-modified dust grain trajectories may be observed by New Horizons, though further modeling efforts are required.

description: AbstractMangroves are important for supporting various marine species and other marine organisms, serving as important breeding grounds and nursery grounds for many important fish species. Overexploitation of mangroves has had a serious impact on marine resources and the livelihoods of people who depend on these resources. According to data from the Fisheries Administration in 2010, approximately 78,405 hectares of mangroves remain. The objectives of this study were to 1) conduct a forest inventory to identify plant species and 2) assess carbon stocks in the study area. The study used the Cambodian National Forest Inventory method, 9 sample plots using circular plots with a radius of 20 m. The results identified nine tree species in the study area: Rhizophora apiculata, Lumnitzera racemosa, Excoecaria agallocha, Avicennia alba, Ceriops decandra, Bruguiera gymnorrhiza, Bruguiera cylindrica, Sonneratia ovata and Sonneratia alba. There was an average of 1,770 ± 268.39 trees per hectare (with DBH ≥ 5 cm). Carbon stocks were estimated to be 46.7 Mg C/ha, equivalent to 171.2 Mg CO2/ha, with a standard error of 47.4. Overall, Excoecaria agallocha, Lumnitzer racemose, Bruguiera gymnorrhiza were the dominant mangrove species, and carbon stocks ranged from 26.9 - 66.5 Mg of carbon per hectare. This study highlights the important ecological and economic importance of mangroves, emphasizing the need for sustainable management to conserve these important resources.Keywords: Above ground biomass, Below ground biomass, Carbon, Species diversity, Mangrove Forest

description: Performing an exact diagonalization of the effective spin problem, a ferromagnetic ground state of kinetic origin is shown to emerge in a system of $N$ strongly correlated electrons on a $L$-site ring ($L > N$). This phenomenon is brought about by the quantum necklace statistics originated from the no double occupancy constraint leading to a fractional shifted electron momentum quantization. As a consequence of such special energy level distribution, the kinetic ferromagnetism is stable only for $N=3$. For odd $N>3$ the fully polarized FM state energy is only a local minimum but it is protected by a finite energy barrier that inhibits one spin-flip processes. The metastable ferromagnetic state survives perturbations of small magnitude opening up a possibility of being experimentally observed by an appropriate tuning of the interdot tunneling amplitudes in currently available quantum dot arrays.

description: Kagome superconductors AV3Sb5 (A = K, Rb, and Cs) have attracted considerable attention due to their intriguing combination of unique electron correlations and nontrivial band topology. The interplay of these fundamental aspects gives rise to a diverse array of exotic electronic phenomena, including superconductivity and charge density wave (CDW) states. In this review, we present recent advancements in the study of the electronic band structure of AV3Sb5 using angle-resolved photoemission spectroscopy (ARPES), including the identification of the multiple van Hove singularities near the Fermi level and their close relationship with the CDW transition, spectroscopic features related to CDW-induced symmetry breakings, as well as direct observations of nodeless superconducting gaps and moderate electron-phonon couplings through ultrahigh-resolution ARPES, providing critical insights into the origins of CDW order and electron pairing symmetry. By synthesizing these key ARPES findings, this review aims to deepen our understanding of kagome-related physics.

description: AbstractMangroves are important for supporting various marine species and other marine organisms, serving as important breeding grounds and nursery grounds for many important fish species. Overexploitation of mangroves has had a serious impact on marine resources and the livelihoods of people who depend on these resources. According to data from the Fisheries Administration in 2010, approximately 78,405 hectares of mangroves remain. The objectives of this study were to 1) conduct a forest inventory to identify plant species and 2) assess carbon stocks in the study area. The study used the Cambodian National Forest Inventory method, 9 sample plots using circular plots with a radius of 20 m. The results identified nine tree species in the study area: Rhizophora apiculata, Lumnitzera racemosa, Excoecaria agallocha, Avicennia alba, Ceriops decandra, Bruguiera gymnorrhiza, Bruguiera cylindrica, Sonneratia ovata and Sonneratia alba. There was an average of 1,770 ± 268.39 trees per hectare (with DBH ≥ 5 cm). Carbon stocks were estimated to be 46.7 Mg C/ha, equivalent to 171.2 Mg CO2/ha, with a standard error of 47.4. Overall, Excoecaria agallocha, Lumnitzer racemose, Bruguiera gymnorrhiza were the dominant mangrove species, and carbon stocks ranged from 26.9 - 66.5 Mg of carbon per hectare. This study highlights the important ecological and economic importance of mangroves, emphasizing the need for sustainable management to conserve these important resources.Keywords: Above ground biomass, Below ground biomass, Carbon, Species diversity, Mangrove Forest

Summary of: Adaptive Metamorphic Testing with Contextual Bandits

description: Metamorphic Testing is a software testing paradigm which aims at using necessary properties of a system-under-test, called metamorphic relations, to either check its expected outputs, or to generate new test cases. Metamorphic Testing has been successful to test programs for which a full oracle is not available or to test programs for which there are uncertainties on expected outputs such as learning systems. In this article, we propose Adaptive Metamorphic Testing as a generalization of a simple yet powerful reinforcement learning technique, namely contextual bandits, to select one of the multiple metamorphic relations available for a program. By using contextual bandits, Adaptive Metamorphic Testing learns which metamorphic relations are likely to transform a source test case, such that it has higher chance to discover faults. We present experimental results over two major case studies in machine learning, namely image classification and object detection, and identify weaknesses and robustness boundaries. Adaptive Metamorphic Testing efficiently identifies weaknesses of the tested systems in context of the source test case.
Risk Response Models and Their Use In Agricultural Policy Evaluation

Subjects: Risk and Uncertainty

description: The previous two papers have discussed the possible effects that proposed public policy may have on risk and uncertainty in the agricultural economic environment. Accordingly, I will argue that, before we can adequately evaluate such policies which create new degrees of risk for agricultural producers, we must have better quantitative knowledge of how fathers will respond to changing risk in adjusting input and production decisions. I will then consider models for estimation of the effects of changing risk in agricultural supply response.
What do you Mean? The Role of the Mean Function in Bayesian Optimisation

description: Bayesian optimisation is a popular approach for optimising expensive black-box functions. The next location to be evaluated is selected via maximising an acquisition function that balances exploitation and exploration. Gaussian processes, the surrogate models of choice in Bayesian optimisation, are often used with a constant prior mean function equal to the arithmetic mean of the observed function values. We show that the rate of convergence can depend sensitively on the choice of mean function. We empirically investigate 8 mean functions (constant functions equal to the arithmetic mean, minimum, median and maximum of the observed function evaluations, linear, quadratic polynomials, random forests and RBF networks), using 10 synthetic test problems and two real-world problems, and using the Expected Improvement and Upper Confidence Bound acquisition functions. We find that for design dimensions $\ge5$ using a constant mean function equal to the worst observed quality value is consistently the best choice on the synthetic problems considered. We argue that this worst-observed-quality function promotes exploitation leading to more rapid convergence. However, for the real-world tasks the more complex mean functions capable of modelling the fitness landscape may be effective, although there is no clearly optimum choice.

Remarks on 't Hooft's Brick Wall Model

description: A semi-classical reasoning leads to the non-commutativity of the space and time coordinates near the horizon of Schwarzschild black hole. This non-commutativity in turn provides a mechanism to interpret the brick wall thickness hypothesis in 't Hooft's brick wall model as well as the boundary condition imposed for the field considered. For concreteness, we consider a noncommutative scalar field model near the horizon and derive the effective metric via the equation of motion of noncommutative scalar field. This metric displays a new horizon in addition to the original one associated with the Schwarzschild black hole. The infinite red-shifting of the scalar field on the new horizon determines the range of the noncommutativ space and explains the relevant boundary condition for the field. This range enables us to calculate the entropy of black hole as proportional to the area of its original horizon along the same line as in 't Hooft's model, and the thickness of the brick wall is found to be proportional to the thermal average of the noncommutative space-time range. The Hawking temperature has been derived in this formalism. The study here represents an attempt to reveal some physics beyond the brick wall model.

description: The retail related diversity is the major concern of this paper. Many extension-oriented contacts indicate that both consumers and retailers in rural towns and counties are intensely concerned with the future of retail trade in their localities. Merchants are naturally concerned because retail volume is the source of their incomes. Consumers in rural counties are concerned with availability of retail consumer goods. Rural merchants may think in terms of sales retention. Availability and retention are two sides of the same coin for the purposes of this paper.
