Radiation Forces Constrain the FRB Mechanism

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: We provide constraints on Fast Radio Burst (FRB) models by careful considerations of radiation forces associated with these powerful transients. We find that the induced-Compton scatterings of the coherent radiation by electrons/positrons accelerate particles to very large Lorentz factors (LF) in and around the source of this radiation. This severely restricts those models for FRBs that invoke relativistic shocks and maser type instabilities at distances less than about $10^{13}$ cm of the neutron star. Radiation traveling upstream, in these models, forces particles to move away from the shock with a LF larger than the LF of the shock front. This suspends the photon generation process after it has been operating for less than ~0.1 ms (observer frame duration). We show that masers operating in shocks at distances larger than $10^{13}$ cm cannot simultaneously account for the burst duration of 1 ms or more and the observed ~1 GHz frequencies of FRBs without requiring an excessive energy budget ($10^{46}$ erg); the energy is not calculated by imposing any efficiency consideration, or other details, for the maser mechanism, but is entirely the result of ensuring that particle acceleration by induced-Compton forces upstream of the shock front does not choke off the maser process. For the source to operate more or less continuously for a few ms, it should be embedded in a strong magnetic field - cyclotron frequency $\gg$ wave frequency - so that radiation forces do not disperse the plasma and shut-off the engine.

description: We analyze Hardy's non-locality argument for two spin-s systems and show that earlier solution in this regard was restricted due to imposition of some conditions which have no role in the argument of non-locality. We provide a compact form of non-locality condition for two spin-s systems and extend it to n number of spin-s particles. We also apply more general kind of non-locality argument still without inequality, to higher spin system.

description: Direct foreign investment (DFI) allows a multinational corporation (MNC) to generate and appropriate extra-normal profits from its unique assets in a foreign market. China has become increasingly attractive for foreign investment over the past 20 years. This entails political risk, but MNCs can reduce the risk by relying heavily on MNC-specific assets, often in the form of tacit knowledge. A joint venture with a local partner creates an incentive for a local stakeholder to shield the DFI from political risks and allows the partner to contribute location-specific assets to the venture, further reducing the MNC's risk.

description: A simple axiomatic characterization of the general (infinite dimensional, noncommutative) Ito algebra is given and a pseudo-Euclidean fundamental representation for such algebra is described. The notion of Ito B*-algebra, generalizing the C*-algebra is defined to include the Banach infinite dimensional Ito algebras of quantum Brownian and quantum Levy motion, and the B*-algebras of vacuum and thermal quantum noise are characterized. It is proved that every Ito algebra is canonically decomposed into the orthogonal sum of quantum Brownian (Wiener) algebra and quantum Levy (Poisson) algebra. In particular, every quantum thermal noise is the orthogonal sum of a quantum Wiener noise and a quantum Poisson noise as it is stated by the Levy-Khinchin theorem in the classical case.

description: Excerpts from the report Introduction: The taking of a sample that will accurately represent the butterfat content of the milk in a single day's delivery by one producer is a problem to which much consideration has been given. Yet, even if each day's delivery is sampled satisfactorily, there remains the problem of accurately representing all the milk delivered during a month in order to establish a basis of payment which will be equally fair to plants and their patrons. The object of the study reported here was to estimate how closely an individual producer's monthly weighted average butterfat percentage is represented by tests of 10- and 15-day composite samples or by samples taken and tested on one or more days during the month. This information would help to reconcile the conflict between cost of sampling and testing and the desire for less variable results.

description: We consider a double-layer system made of two parallel bilayer graphene sheets separated by a dielectric medium. We calculate the finite-temperature electrical conductivity of the first layer due to charged impurities located in two layers. We study the effects of temperature, interlayer distance, dielectric constants and impurity concentration, carrier concentration on the electrical conductivity. We show the importance of charged impurities located in layer II in determining electrical conductivity of the first layer for small interlayer distance. The results in this paper give us more understanding about the long-range charged impurity scattering in bilayer graphene under effect of the second one.

description: Memory effects in the dynamics of open systems have been the subject of significant interest in the last decades. The methods involved in quantifying this effect, however, are often difficult to compute and may lack analytical insight. With this in mind, we consider Gaussian collisional models, where non-Markovianity is introduced by means of additional interactions between neighboring environmental units. By focusing on continuous-variable Gaussian dynamics, we are able to analytically study models of arbitrary size. We show that the dynamics can be cast in terms of a Markovian Embedding of the covariance matrix, which yields closed form expressions for the memory kernel that governs the dynamics, a quantity that can seldom be computed analytically. The same is also possible for a divisibility monotone, based on the complete positivity of intermediate maps. We analyze in detail two types of interactions, a beam-splitter implementing a partial SWAP and a two-mode squeezing, which entangles the ancillas and, at the same time, feeds excitations into the system. By analyzing the memory kernel and divisibility for these two representative scenarios, our results help to shed light on the intricate mechanisms behind memory effects in the quantum domain.

description: This paper investigates the effects of the Canada-U.S. Trade Agreement (CUSTA) on U.S. exports of agricultural products. Econometric analysis found that CUSTA has had a large impact on many U.S. agricultural export categories. All of the consumer-oriented products (except wine and beer), five of the intermediate products, and four of the bulk products had significant CUSTA effects. It is clear that the CUSTA effects have been larger for consumer-oriented food products. There is also evidence that U.S. affiliate sales in Canada have stimulated U.S. exports of consumer-oriented products and intermediate products.

description: In this paper, we extend the phase space of black holes enclosed by a spherical cavity of radius $r_{B}$ to include $V\equiv4πr_{B}^{3}/3$ as a thermodynamic volume. The thermodynamic behavior of Schwarzschild and Reissner-Nordstrom (RN) black holes is then investigated in the extended phase space. In a canonical ensemble at constant pressure, we find that the aforementioned thermodynamic behavior is remarkably similar to that of the anti-de Sitter (AdS) counterparts with the cosmological constant being interpreted as a pressure. Specifically, a first-order Hawking-Page-like phase transition occurs for a Schwarzschild black hole in a cavity. The phase structure of a RN black hole in a cavity shows a strong resemblance to that of the van der Waals fluid. Our results may provide a new perspective for the extended thermodynamics of AdS black holes by analogy with black holes in a cavity.

description: Recently, machine learning methods presented a viable solution for automated classification of image-based data in various research fields and business applications. Scientists require a fast and reliable solution to be able to handle the always growing enormous amount of data in astronomy. However, so far astronomers have been mainly classifying variable star light curves based on various pre-computed statistics and light curve parameters. In this work we use an image-based Convolutional Neural Network to classify the different types of variable stars. We used images of phase-folded light curves from the OGLE-III survey for training, validating and testing and used OGLE-IV survey as an independent data set for testing. After the training phase, our neural network was able to classify the different types between 80 and 99%, and 77-98% accuracy for OGLE-III and OGLE-IV, respectively.

description: BAT99-129 in the LMC is one among a handful of extra-galactic eclipsing Wolf-Rayet binaries known. We present blue, medium-resolution, phase-dependent NTT-EMMI spectra of this system that allow us to separate the spectra of the two components of the binary and to obtain a reliable orbital solution for both stars. We assign an O5V spectral type to the companion, and WN3(h)a to the Wolf-Rayet component. We discuss the spectroscopic characteristics of the system: luminosity ratio, radii, rotation velocities. We find a possible oversynchronous rotation velocity for the O star. Surprisingly, the extracted Wolf-Rayet spectrum clearly shows the presence of blueshifted absorption lines, similar to what has been found in all single hot WN stars in the SMC and some in the LMC. We also discuss the presence of such intrinsic lines in the context of hydrogen in SMC and LMC Wolf-Rayet stars, WR+O binary evolution and GRB progenitors. Altogether, BAT99~129 is the extragalactic counterpart of the well-known Galactic WR binary V444 Cygni.

description: We study a tight binding model including both on site disorder and coupling of the electrons to randomly oriented magnetic moments. The transport properties are calculated via the Kubo-Greenwood scheme, using the exact eigenstates of the disordered system and large system size extrapolation of the low frequency optical conductivity. We first benchmark our method in the model with only structural disorder and then use it to map out the transport regimes and metal- insulator transitions in problems involving (i) scattering from random magnetic moments, and (ii) the combined effect of structural disorder and magnetic scattering. We completely map out the dependence of the d.c conductivity on electron density (n) the structural disorder (Δ) and the magnetic coupling (J'), and locate the insulator-metal phase boundary in the space of n-Δ-J'. These results serve as a reference for understanding transport in systems ranging from magnetic semiconductors to double exchange `colossal magnetoresistance' systems. A brief version of this study appears in our earlier paper Europhys. Lett. vol 65, 75 (2004).

description: Robots are extending their presence in domestic environments every day, being more common to see them carrying out tasks in home scenarios. In the future, robots are expected to increasingly perform more complex tasks and, therefore, be able to acquire experience from different sources as quickly as possible. A plausible approach to address this issue is interactive feedback, where a trainer advises a learner on which actions should be taken from specific states to speed up the learning process. Moreover, deep reinforcement learning has been recently widely utilized in robotics to learn the environment and acquire new skills autonomously. However, an open issue when using deep reinforcement learning is the excessive time needed to learn a task from raw input images. In this work, we propose a deep reinforcement learning approach with interactive feedback to learn a domestic task in a human-robot scenario. We compare three different learning methods using a simulated robotic arm for the task of organizing different objects; the proposed methods are (i) deep reinforcement learning (DeepRL); (ii) interactive deep reinforcement learning using a previously trained artificial agent as an advisor (agent-IDeepRL); and (iii) interactive deep reinforcement learning using a human advisor (human-IDeepRL). We demonstrate that interactive approaches provide advantages for the learning process. The obtained results show that a learner agent, using either agent-IDeepRL or human-IDeepRL, completes the given task earlier and has fewer mistakes compared to the autonomous DeepRL approach.

Demand and Price Analysis

description: Dry bean prices, as received by the grower and the dealer, were analyzed for four different production regions, and for two of the major varieties grown in the US. The dry bean price series were not stationary. Prices for each variety were cointegrated across the production regions and between grower and dealer markets. However causality tests failed to show the dominant regional variety as the price leader. Further, prices of the two varieties were not cointegrated, which indicated that growers would benefit from growing more than one variety at the same time.
Seeing is conceiving : gender, race and visual semantics at the Birmingham Centre for Contemporary Cultural Studies
Creators: name: Carnie, Henry Joseph
Publisher: name: University of British Columbia
Year: 2009

description: This paper deals with the discourses of visuality in the intellectual history of British cultural studies as it developed in the postwar period at the University of Birmingham's Center for Contemporary Cultural Studies (CCCS). Visual representation has long been perceived by western thought as a terrain unaffected by perception, language and conceptions; however, recent thought has contested this notion and in the process problematized cultural "ways of seeing." The paper asks how the subjects of British cultural studies were produced but also how and why they were conceived through a visual discourse. It discusses the extent to which this visual discourse at the CCCS was ruptured by the breaking in of previously "invisible" subjects and how this visual discourse itself actually facilitated this rupture. The paper approaches this discussion through a close analysis of key texts produced at the CCCS. It demonstrates that the intellectual trajectory of British cultural studies at the CCCS involved a shift from an oral means of cultural expression to a visual one and then back to an oral form. It examines how the interventions by thinkers on gender and race influenced this shift. The paper concludes that visuality and orality were held in constant tension throughout the intellectual history of British cultural studies at the CCCS, but that a more inclusive and democratic form of orality finally gained ascendancy over a visuality, which was inherently implicated in social and cultural structures of power.

SED models of AGN

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Present AGN models aiming to account for the observed infrared SEDs consider a physical description of the dust and a solution of the radiative transfer problem. Mid infrared spectra obtained at different spatial scales are presented. They show that PAH bands are detected in starburst regions but significantly reduced near the centre of AGN. This may be explained by examining the heating mechanism of PAHs after hard photon interactions. On the radiative transfer side first a most economic model is presented where three parameters, luminosity, effective size and extinction of the nucleus are varied to obtain SED fits. A full grid of model spectra are made available at: "http://www.eso.org/~rsiebenm/agn_models". This model is sufficient to account for ISO broad band data of a sample of 68 radio galaxies and quasars of the 3CR catalogue. The hot dust component detected is mainly due to small grains and PAHs. In such models, type 1 AGNs are represented by a compact dust distribution with warm grains and weak PAH emission. In AGNs of type 2, the dust appears to be more extended, relatively colder and PAH bands are strong. Realistic AGN models which are consistent with the unification need to explain the overall absence of the 9.7mic. silicate emission feature. This can be done by considering various geometries (tapered discs). Models which combine AGN and starburst activity are presented for galaxies with hidden broad line region. It is found that the AGN torus dominate the mid IR continuum emission and that the starbursts dominate the PAH band as well as the far infrared and submillimeter emission.

Identifying factors influencing utilization of cervical cancer screening among immigrant women in Canada
Creators: name: Chang, Su-Jin
Publisher: name: University of British Columbia
Year: 2009

description: Cervical cancer screening using the Papanicolaou (Pap) smear test has had a significant effect on early detection of invasive cervical cancer. However, the risk of cervical cancer remains high among immigrant women in Canada. The objective of this study was to explore factors influencing the utilization of cervical cancer screening among immigrant women 15-69 years of age in Canada. Data from the 1996-1997 National Population Health Survey were used to conduct a secondary analysis, with logistic regression analysis, of factors associated with use of Pap testing. The findings indicated that 27% of immigrant women in Canada have either never had Pap testing or have had Pap testing completed more than three years ago. With regression analysis, factors significantly related to ever having had Pap testing among immigrant women between 25-69 years of age included: residing 10 years or more in Canada, having a regular doctor, speaking English or French, completion of some post-secondary education, aged 25-39 years, being widowed/divorced/separated, and having been born in US/Europe/Australia. Several interesting interaction effects were noted between income and education, between length of residence in Canada and having a regular doctor, and between education and language use. Being younger and having a regular physician were significantly related to having Pap testing within the past three years. Of these women, the most frequently reported reason for the use of Pap testing was that it was part of a regular check-up. Only a few women experienced problems obtaining Pap testing. Among women who never had a Pap test or had no Pap testing within the last three years, the most common reason for non-use of Pap testing was thinking that it was not necessary. The findings provide direction for identifying immigrant women at risk for not having regular Pap tests. Nurses can help to increase the uptake of Pap testing by providing information about the importance of this relatively simple, life-saving test to immigrant women and by promoting routine physical checkups with a family doctor. Offering women alternative and convenient ways to obtain Pap testing in settings that employ female health-care providers and provide language services may be among the best strategies for improving uptake and regular participation in cervical cancer screening for Canadian immigrant women.

description: While interest in developing strategic alliances within the food system continues to increase, there remains considerable risk when firms adopt such a cooperative strategy. The risk is due in part to the lack of concrete guidelines that illustrate the steps or stages of alliance development and the important strategic and operational decisions required at each stage. The existence of such guidelines would facilitate alliance formation and enable managers and researchers to better understand alliance practice. This paper provides an alliance formation model that incorporates the process of alliance formation with the strategic and operational considerations required for long term success. The model can be used by managers and academicians to develop and understand alliances.

description: DNA N6-methylation (6mA) in Adenine nucleotide is a post replication modification and is responsible for many biological functions. Experimental methods for genome wide 6mA site detection is an expensive and manual labour intensive process. Automated and accurate computational methods can help to identify 6mA sites in long genomes saving significant time and money. Our study develops a convolutional neural network based tool i6mA-CNN capable of identifying 6mA sites in the rice genome. Our model coordinates among multiple types of features such as PseAAC inspired customized feature vector, multiple one hot representations and dinucleotide physicochemical properties. It achieves area under the receiver operating characteristic curve of 0.98 with an overall accuracy of 0.94 using 5 fold cross validation on benchmark dataset. Finally, we evaluate our model on two other plant genome 6mA site identification datasets besides rice. Results suggest that our proposed tool is able to generalize its ability of 6mA site identification on plant genomes irrespective of plant species. Web tool for this research can be found at: https://cutt.ly/Co6KuWG. Supplementary data (benchmark dataset, independent test dataset, comparison purpose dataset, trained model, physicochemical property values, attention mechanism details for motif finding) are available at https://cutt.ly/PpDdeDH.

All the available data cover the time period of 58 years, and include both phases of the maximum and minimum B_e. We determined that the period of the long-term magnetic B_e variations equals 91.1 +/- 3.6 years, with B_e (max) = + 577 +/- 31 G and B_e (min) = -1101 +/- 31 G.

description: Supply chain management has become an increasingly important topic to agribusiness managers during the past five years. Drivers of this trend include buyers seeking higher levels of customer service and efforts by firms to control costs, especially inventory. This case introduces the reader to supply chain management. It would work well either as part of a capstone course, in a special topics course, or in an executive education course. The case explores some of the issues and dilemmas associated with supply chain management efforts at BioAg, a small Midwestern firm that manufacturers agricultural chemicals that are environmentally sensitive.

description: Astrophysical jets are launched from strongly magnetized systems that host an accretion disk surrounding a central object. Here we address the question how to generate the accretion disk magnetization and field structure required for jet launching. We continue our work from Paper I (Mattia & Fendt 2020a), considering a non-scalar accretion disk mean-field $α^2Ω$-dynamo in the context of large scale disk-jet simulations. We now investigate a disk dynamo that follows analytical solutions of mean-field dynamo theory, essentially based only on a single parameter, the Coriolis number. We thereby confirm the anisotropy of the dynamo tensor acting in accretion disks, allowing to relate both the resistivity and mean-field dynamo to the disk turbulence. Our new model recovers previous simulations applying a purely radial initial field, while allowing for a more stable evolution for seed fields with a vertical component. We also present correlations between the strength of the disk dynamo coefficients and the dynamical parameters of the jet that is launched, and discuss their implication for observed jet quantities.

description: Despite the omnipresence of colloidal suspensions, little is known about the influence of shape on phase transformations, especially in nonequilibrium. To date, real-space imaging results are limited to systems composed of spherical colloids. In most natural and technical systems, however, particles are non-spherical and their structural dynamics are determined by translational and rotational degrees of freedom. Using confocal microscopy, we reveal that suspensions of ellipsoidal colloids form an unexpected state of matter, a liquid glass in which rotations are frozen while translations remain fluid. Image analysis unveils hitherto unknown nematic precursors as characteristic structural elements of this state. The mutual obstruction of these ramified clusters prevents liquid crystalline order. Our results give unique insight into the interplay between local structures and phase transformations. This helps to guide applications such as self-assembly of colloidal superstructures and also gives first evidence of the importance of shape on the glass transition in general.

description: We present metallicities, [Fe/H], and elemental abundance ratios, [X/Fe], for a sample of 24 Cepheids in the outer Galactic disk. The sample have Galactocentric distances covering 12 < R_GC (kpc) < 17.2 making them the most distant Galactic Cepheids upon which detailed abundance analyses have been performed. We find sub-solar ratios of [Fe/H] and overabundances of [alpha/Fe], [La/Fe], and [Eu/Fe]. All abundance ratios exhibit a dispersion that exceeds the measurement uncertainties. As seen in our previous studies of old open clusters and field giants, enhanced ratios of [alpha/Fe] and [Eu/Fe] reveal that recent star formation has taken place in the outer disk. The outer disk Cepheids appear to exhibit a bimodal distribution for [Fe/H] and [alpha/Fe]. Most of the Cepheids continue the trends with Galactocentric distance exhibited by Andrievsky's larger Cepheid sample and we refer to these stars as the "Galactic Cepheids". A minority of the Cepheids show considerably lower [Fe/H] and higher [alpha/Fe] and we refer to these stars as the "Merger Cepheids". One signature of a merger event would be composition differences between the "Galactic" and "Merger" Cepheids. The Cepheids satisfy this requirement and we speculate that the distinct compositions suggest that the "Merger Cepheids" may have formed under the influence of significant merger or accretion events. The short lifetimes of the Cepheids reveal that the merger event may be on-going with the Monoceros ring and Canis Major galaxy being possible merger candidates. [Abridged]

description: High-tech information systems can offer competitive advantages to agri-food firms when the systems support a supply chain strategy that suits the demand for the product. This article discusses differences between supply chains for functional versus innovative products and the relevance for managers in agri-food firms. Unique characteristics of agriculture and food products and economic concentration in food industries affect the appropriate supply chain approach.

description: Estimation of optical aberrations from volumetric intensity images is a key step in sensorless adaptive optics for 3D microscopy. Recent approaches based on deep learning promise accurate results at fast processing speeds. However, collecting ground truth microscopy data for training the network is typically very difficult or even impossible thereby limiting this approach in practice. Here, we demonstrate that neural networks trained only on simulated data yield accurate predictions for real experimental images. We validate our approach on simulated and experimental datasets acquired with two different microscopy modalities, and also compare the results to non-learned methods. Additionally, we study the predictability of individual aberrations with respect to their data requirements and find that the symmetry of the wavefront plays a crucial role. Finally, we make our implementation freely available as open source software in Python.

description: Excerpts from the report Introduction: One of the objectives of materials-handling research conducted in Washington State apple houses was to develop and test improved methods for using present equipment and to introduce and test, under actual operating conditions, some of the newer types of equipment not now being used. The program included testing 8 innovations, 5 of which applied to the receiving of apples; 1 to shipping; 1 to the possibility of reducing costs of pallets; and 1 to moving fruit between floor levels. The 8 innovations are reported in the sections that follow. Emphasis was given to costs of receiving fruit because of their importance in warehousing. During the receiving period of 6 to 8 weeks, labor is scarce and it is difficult to regulate smoothly large crews of new help. Also, it is necessary to move fruit promptly and handle it gently to preserve quality. Although these factors cannot be measured in monetary terms, plant managers should consider them in selecting equipment.

description: This research uses binomial and multinomial logistic regression models to identify the factors that influence farmers' adoption of organic technology. Using a sample of 175 farmers growing fresh-market produce in three California counties, the first model examines farmers' choice between conventional-only and organic-only production. The second model compares conventional-only and "dual-method" (combined conventional and organic) production, while the third model employs all three choices in a multinomial model. These results, which indicate that gross sales, direct marketing, number of crops and acres, farmer age, and computer usage are significant determinants, have implications on policies that regulate the organic foods sector.

description: The standard U(N) and SU(N) integrals are calculated in the large N limit. Our main finding is that for an important class of integrals this limit is different for two groups. We describe the critical behaviour of SU(N) models and discuss implications of our results for the large N behaviour of SU(N) lattice gauge theories at finite temperatures and non-zero baryon chemical potential. The key ingredients of our approach are 1) expansion of the integrals into a sum over irreducible representations and 2) calculation of sums over partitions of r of products of dimensions of two different representations of a symmetric group $S_r$.

The "missing" YSOs in the central parsec of the Galaxy: evidence for star formation in a massive accretion disk and a top-heavy IMF

description: Few dozens of young high mass stars orbit Sgr A* at distances as short as 0.1 parsec, where star formation should be quenched by the strong tidal shear from Sgr A*. The puzzling young stellar population is believed to come into existence in one of the two ways: (i) "normal" star formation at several tens of parsec in a very massive star cluster that then spiraled in, or (ii) star formation in situ in a massive self-gravitating disk. We propose to constrain these two scenarios via the expected X-ray emission from young low mass stars that should have formed alongside the massive stars. To this end we compare the recent Chandra observations of X-ray emission from young stars in the Orion Nebula, and the Chandra observations of Sgr A* field. We show that the cluster inspiral model is ruled out irrespectively of the initial mass function (IMF) of the young stars. In addition, for the in situ model, we find that no more than few thousand low-mass stars could have formed alongside the massive stars. This is more than a factor of ten fewer than expected if these stars were formed with the standard IMF as elsewhere in the Galaxy. The young stars in the GC are thus the first solid observational evidence for star formation in AGN disks and also require the IMF of these stars to be top-heavy. We briefly consider implication of these results for AGN in general.
