description: The increasing availability of cloud computing services for science has changed the way scientific code can be developed, deployed, and run. Many modern scientific workflows are capable of running on cloud computing resources. Consequently, there is an increasing interest in the scientific computing community in methods, tools, and implementations that enable moving an application to the cloud and simplifying the process, and decreasing the time to meaningful scientific results. In this paper, we have applied the concepts of containerization for portability and multi-cloud automated deployment with industry-standard tools to three scientific workflows. We show how our implementations provide reduced complexity to portability of both the applications themselves, and their deployment across private and public clouds. Each application has been packaged in a Docker container with its dependencies and necessary environment setup for production runs. Terraform and Ansible have been used to automate the provisioning of compute resources and the deployment of each scientific application in a Multi-VM cluster. Each application has been deployed on the AWS and Aristotle Cloud Federation platforms. Variation in data management constraints, Multi-VM MPI communication, and embarrassingly parallel instance deployments were all explored and reported on. We thus present a sample of scientific workflows that can be simplified using the tools and our proposed implementation to deploy and run in a variety of cloud environments.

description: Teilhabe wird in diesem Beitrag aus ethnomethodologischer Perspektive auf der Ebene der Interaktion betrachtet. Soziale Interaktionen folgen einer Ordnung, die diese für die Interaktionspartner*innen verstehbar und auch handhabbar machen. In einem fortwährenden Prozess richten dabei die Beteiligten ihre (Sprach-)Handlungen aufeinander aus. Im Kontext von Behinderung kann dies eine besondere Herausforderung darstellen. In dem Beitrag wird anhand dreier Interaktionssequenzen herausgearbeitet, wie sich Teilhabe auf der Interaktionsebene darstellen und modellieren lässt.

description: Spectral properties of a quantum circuit are efficiently read out by monitoring the resonance frequency shift it induces in a microwave resonator coupled to it. When the two systems are strongly detuned, theory attributes the shift to an effective resonator capacitance or inductance that depends on the quantum circuit state. At small detuning, the shift arises from the exchange of virtual photons, as described by the Jaynes-Cummings model. Here we present a theory bridging these two limits and illustrate, with several examples, its necessity for a general description of quantum circuits readout.

description: Nano-patterned magnetic materials have opened new venues on the investigation of strongly correlated phenomena including artificial spin-ice systems, geometric frustration, magnetic monopoles, for technologically important applications such as reconfigurable ferromagnetism. With the advent of atomically thin two-dimensional (2D) van der Waals (vdW) magnets a pertinent question is whether such compounds could make their way into this realm where interactions can be tailored so that unconventional states of matter could be assessed. Here we show that square islands of CrGeTe3 vdW ferromagnets distributed in a grid manifest antiferromagnetic correlations, essential to enable frustration resulting in an artificial spin-ice. By using a combination of SQUID-on-tip microscopy, focused ion beam lithography, and atomistic spin dynamic simulations, we show that pristine, isolated CGT flakes as small as 150*150*60 nm3 have tunable dipole-dipole interactions, which can be precisely controlled by their lateral spacing. There is a crossover between non-interacting islands and significant inter-island anticorrelation depending how they are spatially distributed allowing the creation of complex magnetic patterns not observable at the isolated flakes. Our findings suggest that the cross-talk between the nano-patterned magnets can be explored in the generation of even more complex spin configurations where exotic interactions may be manipulated in an unprecedent way.

Sub-GeV flashes in $γ-$ray burst afterglows as probes of underlying bright UV flares

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: Bright optical and X-ray flares have been observed in many Gamma-ray Burst (GRB) afterglows. These flares have been attributed to late activity of the central engine. In most cases the peak energy is not known and it is possible and even likely that there is a significant far-ultraviolet component. These far-ultraviolet photons escape our detection because they are absorbed by the neutral hydrogen before reaching Earth. However, these photons cross the blast wave produced by the ejecta that have powered the initial GRB. They can be inverse Compton upscattered by hot electrons within this blast wave. This process will produce a strong sub-GeV flare that follows the high energy (soft X-ray) tail of the far-UV flare but lasts much longer and can be detected by the upcoming {\em Gamma-Ray Large Area Telescope} (GLAST) satellite. This signature can be used to probe the spectrum of the underlying far-ultraviolet flare. The extra cooling produced by this inverse Compton process can lower the X-ray emissivity of the forward shock and explain the unexpected low early X-ray flux seen in many GRBs.

description: We report on photometry and high resolution spectroscopy of the chemically peculiar Jupiter-family Comet (hereafter JFC) 21P/Giacobini-Zinner. Comet 21P is a well known member of the carbon-chain depleted family but displays also a depletion of amines. We monitored continuously the comet over more than seven months with the two TRAPPIST telescopes (TN and TS), covering a large heliocentric distance range from 1.60 au inbound to 2.10 au outbound with a perihelion at 1.01 au on September 10, 2018. We computed and followed the evolution of the dust (represented by Af$ρ$) and gas production rates of the daughter species OH, NH, CN, C$_3$, and C$_2$ and their relative abundances to OH and to CN over the comet orbit. We compared them to those measured in the previous apparitions. The activity of the comet and its water production rate reached a maximum of (3.72$\pm$0.07)$\times$10$^{28}$ molec/s on August 17, 2018 (r$_h$=1.07 au), 24 days before perihelion. The peak value of A(0)f$ρ$ was reached on the same date (1646$\pm$13) cm in the red filter. The abundance ratios of the various species are remarkably constant over a large range of heliocentric distances, before and after perihelion, showing a high level of homogeneity of the ices in the surface of the nucleus. The behaviour and level of the activity of the comet is also remarkably similar over the last five orbits. About the coma dust colour, 21P shows reflectively gradients similar to JFCs. We obtained a high resolution spectrum of 21P with UVES at ESO VLT one week after perihelion. Using the CN B-X (0,0) violet band, we measured $^{12}$C/$^{13}$C and $^{14}$N/$^{15}$N isotopic ratios of 100$\pm$10 and 145$\pm$10, respectively, both in very good agreement with what is usually found in comets.

description: Electrical and thermal properties of atomically thin two-dimensional (2D) materials are affected by their environment, e.g. through remote phonon scattering or dielectric screening. However, while it is known that mobility and thermal conductivity (TC) of graphene are reduced on a substrate, these effects are much less explored in 2D semiconductors such as MoS$_2$. Here, we use molecular dynamics to understand TC changes in monolayer (1L) and bilayer (2L) MoS$_2$ by comparing suspended, supported, and encased structures. The TC of monolayer MoS$_2$ is reduced from ~117 Wm$^{-1}$K$^{-1}$ when suspended, to ~31 Wm$^{-1}$K$^{-1}$ when supported by SiO$_2$, at 300 K. Encasing 1L MoS$_2$ in SiO$_2$ further reduces its TC down to ~22 Wm$^{-1}$K$^{-1}$. In contrast, the TC of 2L MoS$_2$ is not as drastically reduced, being >50% higher than 1L both when supported and encased. These effects are due to phonon scattering with remote vibrational modes of the substrate, which are partly screened in 2L MoS$_2$. We also examine the TC of 1L MoS$_2$ across a wide range of temperatures (300 to 700 K) and defect densities (up to 5$\times$10$^{13}$ cm$^{-2}$), finding that the substrate reduces the dependence of TC on these factors. Taken together, these are important findings for all applications which will use 2D semiconductors supported or encased by insulators, instead of freely suspended.

description: We broaden the existing empirical literature on environmental regulation and voluntary pollution abatement programs by testing the effects of implicit boycott threats and a firm's participation in a partnership program on its subsequent regulatory oversight using EPA's 33/50 program as a research experiment. Our results are consistent with the hypothesis of a preemptive self-selection to deter consumer boycotts. The findings also indicate that (1) predetermined corrective actions constitute a significant determinant of voluntary participation and (2) EPA reciprocated to voluntary participation by easing regulatory oversight on participants.

description: The classical Smorodinsky-Winternitz systems on the ND sphere, Euclidean and hyperbolic spaces S^N, E^N and H^N are simultaneously approached starting from the Lie algebras so_k(N+1), which include a parametric dependence on the curvature k. General expressions for the Hamiltonian and its integrals of motion are given in terms of intrinsic geodesic coordinate systems. Each Lie algebra generator gives rise to an integral of motion, so that a set of N(N+1)/2 integrals is obtained. Furthermore, 2N-1 functionally independent ones are identified which, in turn, shows that the well known maximal superintegrability of the Smorodinsky-Winternitz system on E^N is preserved when curvature arises. On both S^N and H^N, the resulting system can be interpreted as a superposition of an "actual" oscillator and N "ideal" oscillators (for the sphere, these are alike the actual ones), which can also be understood as N "centrifugal terms"; this is the form seen in the Euclidean limiting case.

description: Abstract

Financial literacy may be the greatest factor to the success of women entrepreneurship which play a crucial role in the Philippine economy. Microenterprises empower women economically, socially, and politically. However, their self-confidence and decision-making abilities are largely influenced by their financial literacy. The unprecedented impact of the COVID 19 Pandemic crisis on microbusinesses have posed challenges for women who have to carry on financial management based on their current financial knowledge. This research determined the level of financial literacy among 50 dry goods vendors in Subic Zambales, Philippines, in terms of their financial knowledge, financial behavior, and financial attitude, the three aspects of financial literacy on how they managed their funds and finances during the pandemic. This quantitative study which used a semi-structured survey showed that the respondents are very highly financially literate, their financial behavior and their financial attitude varies depending on their age. The current findings may be useful for government institutions formulating policies, programs, and services in line with gender and development towards women empowerment. Further research on other influencing factors and needs for enhancing women entrepreneurs’ financial literacy is highly recommended.

description: We consider the non-Gaussianity of the nonlinear density perturbations in a single-field inflationary model when a scalar field couples nonminimally with gravity. Gravity theories with a nonminimal coupling can be transformed into the Einstein gravity with canonical kinetic terms by using a suitable conformal transformation. We find that a nonlinear generalization of the gauge invariant quantity $ζ_i$ is invariant under the conformal transformation. With the help of this conformal invariant property, we calculate the non-Gaussianity, which is characterized by a nonlinear parameter $f_{NL}$, in nonminimal coupled scalar field theory.

description: In this Paper we report on further observations of the third and fourth kilohertz quasi-periodic oscillations (QPOs) in the power spectrum of the low-mass X-ray binary (LMXB) 4U1636-53. These kilohertz QPOs are sidebands to the lower kilohertz QPO. The upper sideband has a frequency 55.5+-1.7 Hz larger than that of the contemporaneously measured lower kilohertz QPO. Such a sideband has now been measured at a significance >6 sigma in the power spectra of three neutron star LMXBs (4U1636-53, 4U1728-34, and 4U1608-52). We also confirm the presence of a sideband at a frequency ~55 Hz less than the frequency of the lower kilohertz QPO. The lower sideband is detected at a 3.5 sigma level, only when the lower kilohertz QPO frequency is between 800 and 850 Hz. In that frequency interval the sidebands are consistent with being symmetric around the lower kHz QPO frequency. The upper limit to the rms amplitude of the lower sideband is significant lower than that of the upper sideband for lower kilohertz QPO frequencies >850 Hz. Symmetric sidebands are unique to 4U1636-53. This might be explained by the fact that lower kilohertz QPO frequencies as high as 800-850 Hz are rare for 4U1728-34 and 4U1608-52. Finally, we also measured a low frequency QPO at a frequency of ~43 Hz when the lower kilohertz QPO frequency is between 700-850 Hz. A similar low-frequency QPO is present in the power spectra of the other two systems for which a sideband has been observed. We briefly discuss the possibility that the sideband is caused by Lense-Thirring precession.

description: Across the world, scholars are racing to predict the spread of the novel coronavirus, COVID-19. Such predictions are often pursued by numerically simulating epidemics with a large number of plausible combinations of relevant parameters. It is essential that any forecast of the epidemic trajectory derived from the resulting ensemble of simulated curves is presented with confidence intervals that communicate the uncertainty associated with the forecast. Here we argue that the state-of-the-art approach for summarizing ensemble statistics does not capture crucial epidemiological information. In particular, the current approach systematically suppresses information about the projected trajectory peaks. The fundamental problem is that each time step is treated separately in the statistical analysis. We suggest using curve-based descriptive statistics to summarize trajectory ensembles. The results presented allow researchers to report more representative confidence intervals, resulting in more realistic projections of epidemic trajectories and -- in turn -- enable better decision making in the face of the current and future pandemics.

description: Leadership studies research reveals that political leaders’ beliefs affect their political and policymaking behaviour, especially in times of crisis. Moreover, the level of flexibility of these beliefs influences the likelihood that groups of leaders come to collective decisions. Insight into when and why political leaders do, in fact, change their beliefs is sorely lacking. This paper uses fuzzy-set Qualitative Comparative Analysis (fsQCA) to examine the antecedents of belief changes among 12 European leaders, all working in the realm of economic policy. Its findings reveal how increases in unemployment and unsustainable debt, as well as different government ideologies and increases in Euroscepticism lead to economic belief changes. In so doing, this paper begins to open the ‘black box’ of when, why, and under what conditions leaders change their beliefs.

description: In this paper, we study the model of the late universe with the homogeneous, isotropic and flat Friedmann-Robertson-Walker metric, where the source of the gravitational field is based on the fermion and boson field, with the Maxwell term $F_{μν}F^{μν} $ in four dimensions. The actuation of the Maxwell term for the Einstein gravity makes it possible to find new approaches to solve the problem of the observed accelerated expansion of the universe. Energy conditions have been obtained and studied. These conditions impose very simple and model-independent restrictions on the behaviour of energy density and pressure since they do not require a specific equation of state of matter. To consider the model, the energy conditions NEC, WEC, DEC are realized, and the SEC condition is violated. The boson and fermion fields are responsible for the accelerated regime at early times, but since the total pressure is tending toward zero for large times, a transition to a decelerated regime occurs. Maxwell field is crucial only in the early times.

description: An important policy decision in managing invasive species is how to allocate resources between activities aimed at preventing the arrival of new pests - including additional arrivals of existing pests - and activities aimed at reducing the damages done by species that are already here. We develop a dynamic model for managing a generic invasive pest with an uncertain arrival date. The optimal conditions reveal that it is generally more efficient to spend a larger share of outlays for exclusion activities before a species arrives than after it is known to be here. They also show that outlays should be allocated such that the marginal costs of control measures equal the benefits from the marginal reduction of the species' population growth rate, and the marginal costs of exclusion measures equal the benefits from the marginal reduction of the rate of subsequent arrivals.

description: We study how theories defined in (extra-dimensional) spaces with localized defects can be described perturbatively by effective field theories in which the width of the defects vanishes. These effective theories must incorporate a ``classical'' renormalization, and we propose a renormalization prescription a la dimensional regularization for codimension 1, which can be easily used in phenomenological applications. As a check of the validity of this setting, we compare some general predictions of the renormalized effective theory with those obtained in a particular ultraviolet completion based on deconstruction.

description: This paper explores the motives for inter-household private transfers in rural Burkina Faso. Given the importance of private transfers in household income, quantitatively evaluating the response of private transfers to recipient incomes is informative for the design and the implementation of public interventions, such as policy alleviation programs, which often include transfer programs. To the extent that private transfers interact with public ones, the overall impact of public transfers might be offset, leaving income distribution unchanged. I use the transfers model proposed by Cox, and two national surveys from Burkina to test whether private transfers are motivated by altruism, exchanges or by risk sharing objectives. The econometric estimations control for income endogeneity via instrumental variables, and use three alternative specifications: a spline regression, which is standard in the literature, a friction model which controls for the large fraction of non-participants, and a partial linear model which relaxes the functional form assumption between transfers and income. The findings support the equalizing effects of private transfers. Furthermore, transfers received are reduced by pre-transfers incomes and the effect is larger for low income households. These results support altruistic motives for transfers. In the highest quartile, exchanges motives seem to prevail as indicated by the semi-parametric explorations. Transfers are also used to cope with income risk, although the response to transitory income shocks is relatively small. Overall, the findings provide evidence on the interactions between private and public transfers, which may limit the net effects of public interventions which use transfers to pursue income equality objectives.

description: The proposed modifications in the forthcoming update of the National Building Code of Canada and insufficient information on the vibration behaviour of Canadian woodframe buildings prompted this investigation of the dynamic behaviour of woodframe houses in Canada. The objectives of this thesis are to gain a better understanding of the dynamic characteristics of single-family woodframe buildings in Canada, to conduct a comprehensive literature study on previous research, to assess whether or not ambient vibration testing can be used effectively for determining the vibration characteristics of woodframe houses and to investigate the use of joint time-frequency technique in the vibration studies of woodframe houses. A variety of full-scale dynamic tests, such as shake table earthquake simulation, ambient and forced vibration tests, were conducted at the University of British Columbia on single-family low-rise woodframe houses with the aim to study the dynamic behaviour of this type of structure. A number of field tests were conducted to collect complementary data for existing timber buildings. The vibration data was analyzed by different analysis methodologies. To study the vibration behaviour of woodframe houses before and after earthquake simulations, time and frequency domain analysis methods, such as frequency domain decomposition and stochastic subspace iteration, were employed. To investigate the behaviour throughout the earthquake simulation, joint time- frequency analyses were performed. Among the analyses performed the joint time-frequency analysis is a very powerful tool, which not only provides insight into dynamic characteristics of structures that are not available through frequency domain alone, but also can explain irregular shifts in frequency and verify the results from other analyses. The investigation of vibration characteristics of woodframe houses provided a good understanding of how the natural frequency of the structure changes and how this change is related to the amount of damage observed during each test. The fundamental periods determined from the conducted experiments were in the range of 0.3 to 0.6 seconds and corresponding damping ratios between 3.6 to 16 percent. These periods are significantly longer than the periods suggested by the code formulae. For dynamic testing of buildings the ambient vibration testing method is being recommended, since it is a non-destructive and relatively inexpensive testing method. Frequency results of ambient vibration testing method are found to be typically higher than those obtained from forced vibration testing. Since the latter is considered to be closest to the real frequencies of houses subjected to strong motion, a correlation was done to correct the ambient vibration results.

description: A total of 286 marine fishes of “Dicentrarchus labrax, Dicentrarchus punctatus and Sparus aurata” were collected from Suez Canal in Ismailia Province, Egypt. Abundant mixed parasitic infestation implicating Cymothoid isopods, Lernanthropus, Caligus, Praniza larvae of Gnathiids, Monogeneans and Digeneans was frequently seen. There were double and tripartite parasitism and a quaternary parasitism especially by crustaceans. The total prevalence of mixed parasitic infestation was 23.42% among examined fishes, and D. labrax is a prospect host for mixed parasitic infestations (56.52%). The histopathological picture was recorded as a completed detachment or degeneration of primary gill lamellae, severe congestion and hyperplasia. Results of this study provided the parasites involved in mixed infestation and their effect on the fish health.
Damped Lyman-$α$ absorbers and atomic hydrogen in galaxies: the view of the GAEA model

description: Using the GAEA semi-analytic model, we analyse the connection between Damped Lyman-$α$ systems (DLAs) and HI in galaxies. Our state-of-the-art semi-analytic model is tuned to reproduce the local galaxy HI mass function, and that also reproduces other important galaxy properties, including the galaxy mass - gas metallicity relation. To produce catalogs of simulated DLAs we throw $10^5$ random lines of sight in a composite simulated volume: dark matter haloes with log$(\frac{M_{200}}{ M_{\odot}}) \geq 11.5$ are extracted from the Millennium Simulation, while for $9.2 \leq \log(\frac{M_{200}}{ M_{\odot}})<11.5$ we use the Millennium II, and for $8 \leq \log(\frac{M_{200}}{M_{\odot}}) < 9.2$ a halo occupation distribution model. At $2 < z < 3$, where observational data are more accurate, our fiducial model predicts the correct shape of the column density distribution function, but its normalization falls short of the observations, with the discrepancy increasing at higher redshift. The agreement with observations is significantly improved increasing both the HI masses and the disk radii of model galaxies by a factor 2, as implemented 'a posteriori' in our $2M-2R$ model. In the redshift range of interest, haloes with $M_{200} \geq {10}^{11} M_{\odot}$ give the major contribution to $Ω_{\rm DLA}$, and the typical DLA host halo mass is $\sim {10}^{11} M _{\odot}$. The simulated DLA metallicity distribution is in relatively good agreement with observations, but our model predicts an excess of DLAs at low metallicities. Our results suggest possible improvements for the adopted modelling of the filtering mass and metal ejection in low-mass haloes.

description: The supply response and input demand by farmers using modern rice technology in Laguna, Philippines were estimated using profit function analysis. The results indicate that farmers do maximise short-term profits and respond to price changes efficiently. The supply elasticity of rice with respect to its own price was approximately unity. Changes in real wages were estimated to have a greater impact on rice profit and supplies than changes in the real prices of mechanised land preparation, fertiliser or pesticides. Production elasticities derived from the profit function were consistent with those estimated directly from the underlying production function.

description: We study the problem of making item recommendations to ephemeral groups, which comprise users with limited or no historical activities together. Existing studies target persistent groups with substantial activity history, while ephemeral groups lack historical interactions. To overcome group interaction sparsity, we propose data-driven regularization strategies to exploit both the preference covariance amongst users who are in the same group, as well as the contextual relevance of users' individual preferences to each group. We make two contributions. First, we present a recommender architecture-agnostic framework GroupIM that can integrate arbitrary neural preference encoders and aggregators for ephemeral group recommendation. Second, we regularize the user-group latent space to overcome group interaction sparsity by: maximizing mutual information between representations of groups and group members; and dynamically prioritizing the preferences of highly informative members through contextual preference weighting. Our experimental results on several real-world datasets indicate significant performance improvements (31-62% relative NDCG@20) over state-of-the-art group recommendation techniques.

Optimal Softening for N-Body Halo Simulations

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We propose to determine the optimal softening length in N-body halo simulations by minimizing the ensemble-average acceleration error at a small radius r0. This strategy ensures that the error never exceeds the optimal value beyond r0. Furthermore, we derive semi-analytic formulae for calculating the acceleration error due to the discreteness of particles and softened gravity, which are validated by direct N-body force calculations. We estimate that current state-of-the-art halo simulations suffer >~6% acceleration error at 1% of the halo virial radius. The error grows rapidly toward the center and could contribute significantly to the uncertainties of inner halo properties.
