Separated before birth: pulsars B2020+28 and B2021+51 as the remnants of runaway stars

description: Astrometric data on the pulsars B2020+28 and B2021+51 suggest that they originated within several parsecs of each other in the direction of the Cyg OB2 association. It was proposed that the pulsars share their origin in a common massive binary and were separated at the birth of the second pulsar following the asymmetric supernova explosion. We consider a different scenario for the origin of the pulsar pair based on a possibility that the pulsars were separated before their birth and that they are the remnants of runaway stars ejected (with velocities similar to those of the pulsars) from the core of Cyg OB2 due to strong three- or four-body dynamical encounters. Our scenario does not require any asymmetry in supernova explosions.

description: No abstracts are to be cited without prior reference to the author.A compilation of target, limit and precautionary reference points for 30 ICES stocks is presented. Spawning stock biomasses and Spawning stock biomasses Per Recruit expressed as a percentage of their respective virgin biomasses are designated by %S and by %SPR. Relations between %S and %SPR adopting a spawning stock-recruitment relation are derived. The relative position of the target, limit and precautionary F levels, as well as their corresponding %SPR and %S (using Ricker S-R relation) are discussed. The results indicate a 1st group (F 0 1, F max and F 30%SPR) behaving as longterm target points, with average %SPR between 23-41% and %S between 47-67%, a 2nd group (Frugh, F1oss, Fsutt and F,n,,i,) behaving as limit points with ¾ SPR between 6-14% and ¾S between 0-30% and finally a 3'd group (Fmea and FMsY) with average %SPR around 18% and %S between 35-38%, that is, behaving as target or as limit reference points. These results suggested that levels of longterm projections of ¾SPR between 20-40% and ¾S between 50-70% can be selected as candidates for target points for a given stock. The expected yield, Y, and the F level should also be compared with Y msy and the most recent F. Those bounds can also provide precautionary reference points. Production models are considered separately as they have different basic assumptions.

description: A quantum computer is a machine that can perform certain calculations much faster than a classical computer by using the laws of quantum mechanics. Quantum computers do not exist yet, because it is extremely difficult to control quantum mechanical systems to the necessary degree. What is more, we do at this moment not know which physical system is the best suited for making a quantum computer (although we have some ideas). It is likely that a mature quantum information processing technology will use (among others) light, because photons are ideal carriers for quantum information. These notes are an expanded version of the five lectures I gave on the possibility of making a quantum computer using light, at the Summer School in Theoretical Physics in Durban, 14-24 January, 2007. There are quite a few proposals using light for quantum computing, and I can highlight only a few here. I will focus on photonic qubits, and leave out continuous variables completely. I assume that the reader is familiar with basic quantum mechanics and introductory quantum computing.

description: No abstracts are to be cited without prior reference to the author.Sockeye salmon stocks originating in the Fraser River provide the backbone of the Canadian commercial salmon fishery. They also have profound social importance for coastal communities and indigenous native peoples in British Columbia. Over 100 individual stocks can be identified by spawning location and adult migratory timing patterns. Unlike non-anadromous fishes, returning spawners for each stock can be observed directly. Most stocks are still recovering from catastrophic mortality inflicted early this century from river blockages and overfishing. We evaluate precl}utionary harvest policies for Fraser River sockeye in mixed-stock fisheries. In particular, we consider economic and social performance measures given uncertainty in stock dynamics. Because of highly variable dynamics, the levels of risk adopted in precautionary management have important social and economic consequences. We show there is a conflict between achieving optimal socio-economic objectives and minimising risk as advocated by the precautionary approach to fisheries management.

description: No abstracts are to be cited without prior reference to the author.Limit and target reference points are used to define management measures for target species within the framework of the precautionary approach. This seems insufficient to meet the demands of ecological objectives. A further integration of fisheries and ecological objectives should be achieved. Currently the status of the North Sea ecosystem is sub-optimal for fisheries and nature. Fisheries yields are below their potential due to overfishing and ecosystem properties are largely influenced by the high levels of fishing effort. This situation calls for a joint action, management measures which restore fish stocks and preserve the natural environment. Recent the development of ecological indicators has been pursued in The Netherlands. They were developed as part of an evaluation tool to assess the ecological status of the North Sea and the ecological effects of human activities. Results of this study can be used to define operational ecological objectives. Shared economic and ecological indicators are considered to be important. Indicators developed by fisheries science may also serve as ecological indicators. Further research on indicators beyond the single species level is needed to meet ecological demands. Examples of some new ecological indicators are presented. Communication between managers, politicians and scientists proved to be crucial to identify shared goals and explicit differences in perception. Concepts integrating socio-economic and ecological objectives such as the Catch per Unit of Effort (CPUE) will be studied further.

description: One or more scalar leptoquarks with masses around a few TeV may provide a solution to some of the flavor anomalies that have been observed. We discuss the impact of such new degrees on baryon number violation when the theory is embedded in a Pati-Salam model. The Pati-Salam embedding can suppress renormalizable and dimension-five baryon number violation in some cases. Our work extends the results of Assad, Grinstein, and Fornal who considered the same issue for vector leptoquarks.

Dynamics of Rotating Accretion Flows Irradiated by a Quasar

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We study the axisymmetric, time-dependent hydrodynamics of rotating flows that are under the influence of supermassive black hole gravity and radiation from an accretion disk surrounding the black hole. This work is an extension of the earlier work presented by Proga, where nonrotating flows were studied. Here, we consider effects of rotation, a position-dependent radiation temperature, density at large radii, and uniform X-ray background radiation. As in the non-rotating case, the rotating flow settles into a configuration with two components (1) an equatorial inflow and (2) a bipolar inflow/outflow with the outflow leaving the system along the pole. However, with rotation the flow does not always reach a steady state. In addition, rotation reduces the outflow collimation and the outward flux of mass and kinetic energy. Moreover rotation increases the outward flux of the thermal energy and can lead to fragmentation and time-variability of the outflow. We also show that a position-dependent radiation temperature can significantly change the flow solution. In particular, the inflow in the equatorial region can be replaced by a thermally driven outflow. Generally, as it have been discussed and shown in the past, we find that self-consistently determined preheating/cooling from the quasar radiation can significantly reduce the rate at which the central BH is fed with matter. However, our results emphasize also a little appreciated feature. Namely, quasar radiation drives a non-spherical, multi-temperature and very dynamic flow. These effects become dominant for luminosities in excess of 0.01 of the Eddington luminosity.

description: No abstracts are to be cited without prior reference to the author.In attempting to manage fisheries, much attention is paid to the avoidance of recruitment overfishing and its attendant economic problems by trying to ensure that stocks remain within safe biological limits, and the avoidance of ecological problems by designing fishing gears which have minimal impact on the sea-bed and on its benthic fauna. This paper uses a cost-benefit analysis approach to show optimal reductions in fishing mortality (F) for maximising total value added (the sum of owners' profits and crew share-based pay), and demonstrates the effect of Marginal Rate of Time Preference (MRTP) future discounting on the calculations; it also discusses the benefits of the resultant reduction of fishing activity for the benthic environment. It further discusses disadvantages of management by reduction of growth overfishing, and postulates possible means of overcoming them, but concludes that very large financial benefits can accrue to the fishery as a wholefrom optimising the rate of exploitation.

description: Many X-ray bright active galactic nuclei (AGN) are predicted to follow an extended stage of obscured black hole growth. In support of this picture we examine the X-ray undetected AGNs in the COSMOS field and compare their host galaxies with X-ray bright AGNs. We examine galaxies with M_\ast>10^{9.5}M_\odot for the presence of AGNs at redshifts $z=0.5-3$. We select AGNs in the infrared using \textit{Spitzer} and \textit{Herschel} detections and use color selection techniques to select AGNs within strongly star forming hosts. We stack \textit{Chandra} X-ray data of galaxies with an IR detection but lacking an X-ray detection to obtain soft and hard fluxes, allowing us to measure the energetics of these AGNs. We find a clear correlation between X-ray luminosity and IR AGN luminosity in the stacked galaxies. We also find that X-ray undetected AGNs all lie on the main sequence -- the tight correlation between SFR and $M_\ast$ that holds for the majority of galaxies, regardless of mass or redshift. This work demonstrates that there is a higher population of obscured AGNs than previously thought.

description: The Variable Star One-shot Project (VSOP) is aimed at (1) providing the variability type and spectral type of all unstudied variable stars, (2) process, publish, and make the data available as automatically as possible, and (3) generate serendipitous discoveries. This first paper describes the project itself, the acquisition of the data, the dataflow, the spectroscopic analysis and the on-line availability of the fully calibrated and reduced data. We also present the results on the 221 stars observed during the first semester of the project. We used the high-resolution echelle spectrographs HARPS and FEROS in the ESO La Silla Observatory (Chile) to survey known variable stars. Once reduced by the dedicated pipelines, the radial velocities are determined from cross correlation with synthetic template spectra, and the spectral types are determined by an automatic minimum distance matching to synthetic spectra, with traditional manual spectral typing cross-checks. The variability types are determined by manually evaluating the available light curves and the spectroscopy. In the future, a new automatic classifier, currently being developed by members of the VSOP team, based on these spectroscopic data and on the photometric classifier developed for the COROT and Gaia space missions, will be used. We confirm or revise spectral types of 221 variable stars from the GCVS. We identify 26 previously unknown multiple systems, among them several visual binaries with spectroscopic binary individual components. We present new individual results for the multiple systems V349 Vel and BC Gru, for the composite spectrum star V4385 Sgr, for the T-Tauri star V1045 Sco, and for DM Boo which we re-classify as a BY Draconis variable. The complete data release can be accessed via the VSOP web site.

description: With a compact PL manifold X we associate a category T(X). The objects of T(X) are all combinatorial manifolds of type X, and morphisms are combinatorial assemblies. We prove that the homotopy equivalence BT (X) \approx BPL(X) holds, where PL(X) is the simplicial group of PL-homeomorphisms. Thus the space BT(X) is a canonical countable (as a CW-complex) model of BPL(X). As a result, we obtain functorial pure combinatorial models for PL fiber bundles with fiber X and a PL polyhedron B as the base. Such a model looks like a T(X)-coloring of some triangulation K of B. The vertices of K are colored by objects of T(X) and the arcs are colored by morphisms in such a way that the diagram arising from the 2-skeleton of K is commutative. Comparing with the classical results of geometric topology, we obtain combinatorial models of the real Grassmannian in small dimensions: BT(S^{n-1}) \approx BO(n) for n=1,2,3,4. The result is proved in a sequence of results on similar models of B\PL(X). Special attention is paid to the main noncompact case X=R^n and to the tangent bundle and Gauss functor of a combinatorial manifold. The trick that makes the proof possible is a collection of lemmas on "fragmentation of a fiberwise homeomorphism", a generalization of the folklore lemma on fragmentation of an isotopy.

description: A small fraction of early-type galaxies (ETGs) show prolate rotation, i.e. they rotate around their long photometric axis. In simulations, certain configurations of galaxy mergers are known to produce this type of rotation. We investigate the association of prolate rotation and signs of galaxy interactions among the observed galaxies. We collected a sample of 19 nearby ETGs with distinct prolate rotation from the literature and inspected their ground-based deep optical images for interaction signs - 18 in archival images and one in a new image obtained with the Milanković telescope. Tidal tails, shells, asymmetric/disturbed stellar halos, or on-going interactions are present in all the 19 prolate rotators. Comparing this with the frequency of tidal disturbance among the general sample of ETGs of a roughly similar mass range and surface-brightness limit, we estimate that the chance probability of such an observation is only 0.00087. We also found a significant overabundance of prolate rotators that are hosting multiple stellar shells. The visible tidal features imply a relatively recent galaxy interaction. That agrees with the Illustris large-scale cosmological hydrodynamical simulation, where prolate rotators are predominantly formed in major mergers during the last 6 Gyr. In the appendix, we present the properties of an additional galaxy, NGC 7052, a prolate rotator for which no deep images are available, but for which an HST image revealed the presence of a prominent shell, which had not been reported before.

description: Control of molecular orientation is emerging as crucial for the characterization of the stereodynamics of kinetics processes beyond structural stereochemistry. The special role played in chiral discrimination phenomena has been particularly emphasized by the authors after their extensive probes of experimental control of molecular alignment and orientation. In this work, the role of the orientation has been demonstrated for the first time in first-principles molecular dynamics simulations: stationary points characterized on potential energy surfaces have been calculated for the study of chemical reactions occurring between the bisulfide anion HS- and oriented prototypical chiral molecules CHFXY (where X = CH3 or CN and Y = Cl or I). The important reaction channels are those corresponding to bimolecular nucleophilic substitution (SN2) and to bimolecular elimination (E2): their relative role has been assessed and alternative pathways due to the mirror forms of the oriented chiral molecule are revealed by the different reactivity of the two enantiomers of CHFCNI in SN2 reaction.

ricostruzione come questo sapere scientifico (la scoperta del cambiamento climatico antropico sostanziata dalla comunità scientifica di 190 paesi) ha influenzato la ricerca, la politica e il discorso pubblico nel nostro paese, l'italia. Il titolo è indicativo quando riassuntivo: Il cambiamento climatico in Italia. Istituzioni scientifiche, politica e discorso pubblico (1988-2012). Esso definisce in maniera puntuale i temi che si tratteranno: una genealogia di fenomeni storici, politici, culturali nati in nuce alla scoperta di questo cambiamento che influenzerà in maniera determinante il modo in cui viviamo, l'ambiente intorno a noi, i modelli di sviluppo, la sicurezza del nostro abitare, la forma delle nostre città. In ogni paese questa complessa scoperta ha avuto impatti differenti, un portato differente sulla ricerca e sullo sviluppo economico.

description: Agricultural mechanization is an area of knowledge that has evolved a lot over the past century, its main actors being agricultural tractors that, in 100 years, have increased their powers by 3,300%. This evolution has resulted in an exponential increase in the field capacity of such machines. However, it has also generated negative results such as excessive consumption of fossil fuel, excessive weight on the soil, very high operating costs, and millionaire acquisition value. This paper aims to present an antiparadigmatic alternative in this area. It is proposing a swarm of small electric robotic tractors that together have the same field capacity as a large tractor with an internal combustion engine. A comparison of costs and field capacity between a 270 kW tractor and a swarm of ten swarm tractors of 24 kW each was carried out. The result demonstrated a wide advantage for the small robot team. It was also proposed the preliminary design of an electric swarm robot tractor. Finally, research challenges were suggested to operationalize such a proposal, calling on the Brazilian Robotics Research Community to elaborate a roadmap for research in the area of swarm robot for mechanized agricultural operations.

description: (abridged) Debris disks around main sequence stars are produced by the erosion and evaporation of unseen parent bodies. AU Microscopii (GJ 803) is a compelling object to study in the context of disk evolution across different spectral types, as it is an M dwarf whose near edge-on disk may be directly compared to that of its A5V sibling beta Pic. We resolve the disk from 8-60 AU in the near-IR JHK' bands at high resolution with the Keck II telescope and adaptive optics, and develop a novel data reduction technique for the removal of the stellar point spread function. The point source detection sensitivity in the disk midplane is more than a magnitude less sensitive than regions away from the disk for some radii. We measure a blue color across the near-IR bands, and confirm the presence of substructure in the inner disk. Some of the structural features exhibit wavelength-dependent positions. The disk architecture and characteristics of grain composition are inferred through modeling. We approach the modeling of the dust distribution in a manner that complements previous work. Using a Monte Carlo radiative transfer code, we compare a relatively simple model of the distribution of porous grains to a broad data set, simultaneously fitting to midplane surface brightness profiles and the spectral energy distribution. Our model confirms that the large-scale architecture of the disk is consistent with detailed models of steady-state grain dynamics. Here, a belt of parent bodies from 35-40 AU is responsible for producing dust that is then swept outward by the stellar wind and radiation pressures. We infer the presence of very small grains in the outer region, down to sizes of ~0.05 micron. These sizes are consistent with stellar mass-loss rates Mdot_* << 10^2 Mdot_sun.

description: No abstracts are to be cited without prior reference to the author.The focus on the precautionary approach, sustainable fisheries and ecological management requires knowledge about the uncertainty of stock assessments. An increasing number of working groups in the ICES system include uncertainty estimates, and new reference points are being developed. When it comes to the quality or the uncertainty of uncertainty estimates and reference points, this is communicated by scarce comments in ACFM reports or working group reports. Uncertainty is difficult to estimate, and to get a picture of the quality of assessments it might be fruitful to stndy not only the data and models used, but also how the models are used by the participants of the ICES working groups. It seems that personal knowledge plays an important role when results from each run are evaluated and the program package is rerun with new options or other data. In this paper I discuss the role personal knowledge plays in stock assessment and how this can reflect the quality of the assessment.

description: Integrated development environments (IDE) play an important role in supporting developers during program comprehension and completion. Many of these supportive features focus on low-level programming and debugging activities. Unfortunately, there is less support in understanding and implementing architectural concerns in the form of patterns, tactics and/or other concerns. In this paper we present ArCode, a tool designed as a plugin for a popular IDE, IntelliJ IDEA. ArCode is able to learn correct ways of using frameworks' API to implement architectural concerns such as Authentication and Authorization. Analyzing the programmer's code, this tool is able to find deviations from correct implementation and provide fix recommendations alongside with graphical demonstrations to better communicate the recommendations with the developers. We showcase how programmers can benefit from ArCode by providing an API misuse detection and API recommendation scenario for a famous Java framework, Java Authentication and Authorization (JAAS) security framework.

Prepayment behavior of Canadian mortgage backed securities
Creators: name: Fu, Seung Tak
Publisher: name: University of British Columbia
Year: 2010

description: Mortgage-Backed securities (MBS) represent a financial instrument which "securitizes" residential first mortgages. Although the trading processes of MBS are similar to those of bonds, there are significant differences between the valuation methods of MBS and other securities. One of the sources of these differences is the possibility of prepayment of the mortgages. This study makes the distinction between full prepayment and partial prepayment. The results of this study suggest that full prepayment is directly related to housing market activities and partial prepayment is affected mainly by the prepayment provision in the mortgage contracts.

description: Reconciling the geology of Mars with models of atmospheric evolution remains a major challenge. Martian geology is characterized by past evidence for episodic surface liquid water, and geochemistry indicating a slow and intermittent transition from wetter to drier and more oxidizing surface conditions. Here we present a new model incorporating randomized injection of reducing greenhouse gases and oxidation due to hydrogen escape, to investigate the conditions responsible for these diverse observations. We find that Mars could have transitioned repeatedly from reducing (H2-rich) to oxidizing (O2-rich) atmospheric conditions in its early history. Our model predicts a generally cold early Mars, with mean annual temperatures below 240 K. If peak reducing gas release rates and background CO2 levels are high enough, it nonetheless exhibits episodic warm intervals sufficient to degrade crater walls, form valley networks and create other fluvial/lacustrine features. Our model also predicts transient buildup of atmospheric O2, which can help explain the occurrence of oxidized mineral species such as manganese oxides at Gale Crater. We suggest that the apparent Noachian--Hesperian transition from phyllosilicate deposition to sulfate deposition around 3.5 billion years ago can be explained as a combined outcome of increasing planetary oxidation, decreasing groundwater availability and a waning bolide impactor flux, which dramatically slowed the remobilization and thermochemical destruction of surface sulfates. Ultimately, rapid and repeated variations in Mars' early climate and surface chemistry would have presented both challenges and opportunities for any emergent microbial life.

description: We make conjectures on the moments of the central values of the family of all elliptic curves and on the moments of the first derivative of the central values of a large family of positive rank curves. In both cases the order of magnitude is the same as that of the moments of the central values of an orthogonal family of L-functions. Notably, we predict that the critical values of all rank 1 elliptic curves is logarithmically larger than the rank 1 curves in the positive rank family. Furthermore, as arithmetical applications we make a conjecture on the distribution of a_p's amongst all rank 2 elliptic curves, and also show how the Riemann hypothesis can be deduced from sufficient knowledge of the first moment of the positive rank family (based on an idea of Iwaniec).
