THE VITAL EXODUS | ÉXODO VITAL
Creators: name: Judith Alalú, L.
name: Odette A. Vélez, V.
Publisher: name: Ecopoiesis: eco-human theory and practice
Year: 2020

description: This multi-arts project arose from the encounter between the painting of Judith and the poetry of Odette. Inspired by the intermodal aspect of the expressive arts, which promotes the practice of diverse artistic languages, Judith invited Odette to get to know her paintings and explore the possibility of creating poems in response to them. The verses arrived and this is how Vital Exodus came about, a meeting of visual and poetic images.

description: We study the critical depinning current Jc versus the applied magnetic flux Phi, for quasiperiodic (QP) chains and 2D arrays of pinning centers placed on the nodes of a five-fold Penrose lattice. In QP chains, the peaks in Jc(Phi) are determined by a sequence of harmonics of the long and short segments of the chain. The critical current Jc(Phi) has a remarkable self-similarity. In 2D QP pinning arrays, we predict analytically and numerically the main features of Jc(Phi), and demonstrate that the Penrose lattice of pinning sites provides an enormous enhancement of Jc(Phi), even compared to triangular and random pinning site arrays. This huge increase in Jc(Phi) could be useful for applications.

Multi-dimensional population modelling using frbpoppy: magnetars can produce the observed Fast Radio Burst sky

description: Fast Radio Bursts (FRBs) are energetic, short, bright transients that occur frequently over the entire radio sky. The observational challenges following from their fleeting, generally one-off nature have prevented identification of the underlying sources producing the bursts. As the population of detected FRBs grows, the observed distributions of brightness, pulse width and dispersion measure now begin to take shape. Meaningful direct interpretation of these distributions is, however, made impossible by the selection effects that telescope and search pipelines invariably imprint on each FRB survey. Here we show that multi-dimensional FRB population synthesis can find a single, self-consistent population of FRB sources that can reproduce the real-life results of the major ongoing FRB surveys. This means that individual observed distributions can now be combined to derive the properties of the intrinsic FRB source population. The characteristics of our best-fit model for one-off FRBs agree with a population of magnetars. We extrapolate this model and predict the number of FRBs future surveys will find. For surveys that have commenced, the method we present here can already determine the composition of the FRB source class, and potentially even its subpopulations.

description: For years economists have urged policymakers to use market-based approaches such as cap-and-trade programs or emission taxes to control pollution. The SO2 allowance market created by Title IV of the 1990 U.S. Clean Air Act Amendments represents the first real test of the wisdom of economists' advice. Subsequent urban and regional applications of NOx emission allowance trading took shape in the 1990s in the United States, culminating in a second large experiment in emission trading in the eastern United States that began in 2003. This paper provides an overview of the economic rationale for emission trading and a description of the major U.S. programs for sulfur dioxide (SO2) and nitrogen oxides (NOx). We evaluate these programs along measures of performance including cost savings, environmental integrity, and incentives for technological innovation. We offer lessons for the design of future programs including, most importantly, those reducing carbon dioxide.
Laplacian modes as a filter

Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We compute low-lying eigenmodes of the gauge covariant Laplace operator on the lattice at finite temperature. For classical configurations we show how the lowest mode localizes the monopole constituents inside calorons and that it hops upon changing the boundary conditions. The latter effect we observe for thermalized backgrounds, too, analogously to what is known for fermion zero modes. We propose a new filter for equilibrium configurations which provides link variables as a truncated sum involving the Laplacian modes. This method not only reproduces classical structures, but also preserves the confining potential, even when only a few modes are used.

description: Much has been written about the economic and environmental performance of U.S. emissions trading programs for "acid rain" (sulfur dioxide) and nitrogen oxides. Less explored have been the unique roles and interactions of environmental regulators and the companies they regulate. I first examine how these roles change the way that regulators and companies operate within their own organizations and with each other. Next, I use examples from U.S. trading programs to illustrate the design and administrative features that allow program administrators and industry to best fulfill their respective roles. Finally, I examine briefly whether these features are present in the EU Emissions Trading System and determine the implications for its effectiveness.

description: The author reflects on the significance of fear of nature, resulting from the inability to establish complete control over it, or manage it. In the process of knowing nature, a person nevertheless gains a certain degree of control over it at the cost of losing fear, which, he believes, is one of the prerequisites for creative imagination. The author reveals the contradictory nature of human relationship with nature on the example of his experience in communicating with the forest at different periods of his life.

description: Large panels of etched plastic, situated aboard the Skylab Space Station and inside the Ohya quarry near Tokyo, have been used to set limits on fluxes of cosmogenic particles. These plastic particle track detectors also provide the best sensitivity for some heavy dark matter that interacts strongly with nuclei. We revisit prior dark matter bounds from Skylab, and incorporate geometry-dependent thresholds, a halo velocity distribution, and a complete accounting of observed through-going particle fluxes. These considerations reduce the Skylab bound's mass range by a few orders of magnitude. However, a new analysis of Ohya data covers a portion of the prior Skylab bound, and excludes dark matter masses up to the Planck mass. Prospects for future etched plastic dark matter searches are discussed.

description: This article is based on a description of three geographical locations with which significant events in the author’s life are associated. All these locations are in one way or another connected with economic activity, which has an increasing influence on cultural and natural environments. The author believes that all three examples show that all ecology is now social and cultural ecology. At the same time, the three places indicate a different approach of people to the organization of their environments. People and the environment are more affected when economic benefits are paramount. The situation changes when beauty becomes the ultimate criterion for the organization of the environment and its “ecology.”

A network processor based message manager for MPI
Creators: name: Keppitiyagama, Chamath Indika
Publisher: name: University of British Columbia
Year: 2009

description: We have implemented a system called MPI-NP II, which is an MPI specific messaging system for the Myrinet System Area Networks (SAN). It consists of a lowlevel message manager executing on the LANai processor of the Myrinet Network Interface Card (NIC), a thin host interface layer, and LAM-MPI, a public domain version of MPI. MPI-NP II is a re-design of MPI-NP that simplifies and improves the performance of the original implementation. MPI-NP differs from other low-level messaging systems in that it off-loads some of the MPI specific communication tasks onto the network processor. In particular, it manages MPI message envelopes and can progress messages asynchronously from the host. It realizes three of the goals stated in the MPI standard, namely; zero-copy messaging, overlap of communication and computation, and off-loading tasks to a communication co-processor. In addition, it greatly simplifies and reduces host/NIC interaction and makes it possible to support broadcasting on the NIC. The design MPI-NP II introduces the concept of a microchannel, which is analogous to an independent thread on the NIC whose task is to deliver a specific message. The message manager allows for multiple outstanding send/receive requests and guarantees message delivery based on the available envelope resources, independent of the message size. We achieve these design goals without unduly burdening the slow network processor. MPI-NP II has a minimum message latency of 22 microseconds and a maximum bandwidth of 92MB/s. These values are comparable to other low-level messaging systems but with the added benefit of being able to overlap communication and computation.

description: Many communities on the urban fringe are implementing a range of policies to preserve farmland and open space, cluster residential development, and guide development to areas with existing infrastructure. These efforts are an attempt to control overall growth and the concomitant loss in open space and also to counter a trend toward the so-called large lot development that often takes place in these areas. Planners have argued that policies to manage density are the most important local policy focus for urban areas in the coming years. It is possible that large lot development and sprawl are themselves the result of government policy. Most local governments use zoning to establish minimum acreage requirements for each residential dwelling unit; in ex-urban localities, these limits are often quite high. Developers might build a subdivision with average lot sizes greater than the minimum but they cannot by law go below it. Some researchers have argued, however, that the spatial patterns of development are simply the natural result of household preferences and market forces. In this paper, we address the question of whether zoning limits are the primary cause of lowdensity, sprawling development or whether market forces tend to dictate this outcome. If zoning limits account for low-density development in at least some cases, how would development patterns be different if there had been no such rules? We begin by constructing a simple model of the developer decision about the density of new development. The subdivision is the unit of observation, and developers must weigh both demand and cost considerations in choosing density, in addition to complying with zoning restrictions that vary across parcels. We apply the model using parcel-level data from a region where zoning rules vary but are exogenous to the period under study. Calvert County, Maryland, near Washington, DC, is an historically rural county that has experienced rapid growth in recent years. The county has a transferable development rights (TDRs) program that has led to a great deal of variability in the intensity of development across properties. We are able to not only examine the extent to which zoning has contributed to large lot development but also to determine the economic forces that underlie density decisions. Finally, we are able to forecast how density would have been different in the absence of zoning rules by estimating a Tobit equation that is censored for the observations constrained by zoning.
LYRA I: Simulating the multi-phase ISM of a dwarf galaxy with variable energy supernovae from individual stars

description: We introduce the LYRA project, a new high resolution galaxy formation model built within the framework of the cosmological hydro-dynamical moving mesh code AREPO. The model resolves the multi-phase interstellar medium down to 10 K. It forms individual stars sampled from the initial mass function (IMF), and tracks their lifetimes and death pathways individually. Single supernova (SN) blast waves with variable energy are followed within the hydrodynamic calculation to interact with the surrounding interstellar medium (ISM). In this paper, we present the methods and apply the model to a $10^{10} M_{\odot}$ isolated halo. We demonstrate that the majority of supernovae are Sedov-resolved at our fiducial gas mass resolution of $4 M_{\odot}$. We show that our SN feedback prescription self-consistently produces a hot phase within the ISM that drives significant outflows, reduces the gas density and suppresses star formation. Clustered SN play a major role in enhancing the effectiveness of feedback, because the majority of explosions occur in low density material. Accounting for variable SN energy allows the feedback to respond directly to stellar evolution. We show that the ISM is sensitive to the spatially distributed energy deposition. It strongly affects the outflow behaviour, reducing the mass loading by a factor of 2-3, thus allowing the galaxy to retain a higher fraction of mass and metals. LYRA makes it possible to use a comprehensive multi-physics ISM model directly in cosmological (zoom) simulations of dwarf and higher mass galaxies.

description: This paper examines current agricultural trade negotiations at the World Trade Organization, with particular attention to the relationship between liberalization and developing countries' economic growth and food security. Agriculture remains one of the most highly protected arenas of international trade. The cost of such protection falls particularly hard on developing countries, where agriculture typically accounts for a much higher share of economic output, exports, and employment than in developed countries. Although the 1994 Uruguay Round of trade talks succeeded in bringing agriculture into the rules-based trading system, it did little to actually reduce agricultural trade protection. This paper describes how three important actors in the agricultural trading system-the United States, the European Union, and developing countries-are positioning themselves in the current talks to deal with the unfinished business from the Uruguay Round.

description: We present time-resolved FUV spectra of the dwarf novae SS Cyg and WX Hyi in quiescence from observations using the Hopkins Ultraviolet Telescope on the Astro-1 and Astro-2 Space Shuttle missions and the Goddard High Resolution Spectrograph on the Hubble Space Telescope. Both dwarf novae are characterized by blue continua that extend to the Lyman limit punctuated by broad emission lines including transitions of O VI, N V, Si IV, and C IV. The continuum of WX Hyi can be fit with a white dwarf model with physically reasonable model parameters, but neither system actually shows unambiguous signatures of white dwarf emission. The shape and flux of the spectrum of SS Cyg cannot be self-consistently reconciled with a white dwarf providing all of the FUV continuum flux. Combination white dwarf/disk or white dwarf/optically thin plasma models improve the fit but still do not give physically reasonable model parameters for a quiescent dwarf nova. Assuming that the UV emission lines arise from the disk, the line shapes indicate that surface fluxes fall roughly as R^{-2} in both systems. Fits to the double-peaked line profiles in SS Cyg indicate that the FUV line forming region is concentrated closer to the white dwarf than that of the optical lines and provide no evidence of a hole in the inner disk. Although the flux from SS Cyg was relatively constant during all of our observations, WX Hyi showed significant variability during the GHRS observations. In WX Hyi, the line and continuum fluxes are (with the exception of He II) highly correlated, indicating a link between the formation mechanisms of the line and continuum regions.

description: A comparative study is performed of a deformed mean field theory, represented by the cranked Nilsson-Strutinsky (CNS) model, and the spherical shell model. Energy spectra, occupation numbers, B(E2)-values, and spectroscopic quadrupole moments in the light pf shell nuclei are calculated in the two models and compared. The result is also compared to available experimental data which are generally well described by the shell model. Although the Nilsson-Strutinsky calculation does not include pairing, both the subshell occupation numbers and quadrupole properties are found to be rather similar in the two models. It is also shown that ``unpaired'' shell model calculations produce very similar energies as the CNS at all spins. The role of the pairing energy in the description of backbending and signature splitting in odd-mass nuclei is also discussed.

description: Context: Hyper-velocity stars move so fast that only a supermassive black hole (SMBH) seems to be capable to accelerate them. Hence the Galactic centre (GC) is their only suggested place of origin. Edelmann et al. (2005) found the early B-star HE0437-5439 to be too short-lived to have reached its current position in the Galactic halo if ejected from the GC, except if being a blue straggler. Its proximity to the LMC suggested an origin from this galaxy. Aims: The chemical signatures of stars at the GC are significantly different from those in the LMC. Hence, an accurate measurement of the abundance pattern of HE0437-5439 will yield a new tight constraint on the place of birth of this star. Methods: High-resolution spectra obtained with UVES on the VLT are analysed using state-of-the-art non-LTE modelling techniques. Results: We measured abundances of individual elements to very high accuracy in HE0437-5439 as well as in two reference stars, from the LMC and the solar neighbourhood. The abundance pattern is not consistent at all with that observed in stars near the GC, ruling our an origin from the GC. However, there is a high degree of consistency with the LMC abundance pattern. Our abundance results cannot rule out an origin in the outskirts of the Galactic disk. However, we find the life time of HE0437-5439 to be more than 3 times shorter than the time of flight to the edge of the disk, rendering a Galactic origin unlikely. Conclusions: Only one SMBH is known to be present in Galaxy and none in the LMC. Hence the exclusion of an GC origin challenges the SMBH paradigm. We conclude that there must be other mechanism(s) to accelerate stars to hyper-velocity speed than the SMBH. We draw attention to dynamical ejection from dense massive clusters, that has recently been proposed by Gvaramadze et al. (2008).

As an application, we study the case for which the thermal dimension is reduced to two.

description: Recent CP violation results in B decays suggest that Z penguins may have large weak phase. This can be realized by the four generation (standard) model. Concurrently, B to Xs l+ l- and Bs mixing allow for sizable Vt's* Vt'b only if it is nearly imaginary. Such large effects in b to s transitions would affect s to d transitions, as kaon constraints would demand Vt'd different from zero. Using Gamma(Z to b bbar) to bound |Vt'b|, we infer sizable |Vt's| < |Vt'b| < |Vus|$. Imposing epsilon_K, K+ to pi+ nu nubar and epsilon'/epsilon constraints, we find Vt'd* Vt's = few x 10^(-4) with large phase, enhancing KL to pi0 nu nubar to 5x10^(-10) or even higher. Interestingly, Delta_mBd and sin(2PhiBd) are not much affected, as |Vt'd* Vt'b| << |Vtd* Vtb| = 0.01.

description: In this paper, we review 20 relatively recent empirical studies of telecommuting, all of which focus on the trip reduction perspective. The studies include earlier ones with smaller datasets, such as some pilot studies of individual employers, and more recent studies based on broader surveys of both telecommuters and nontelecommuters. We focus on the results of the studies with respect to participation and frequency of telecommuting, the effects on vehicle-miles-traveled (VMT) and trips, and in some cases, the impacts on emissions and air quality. Although there does not seem to be a consensus, there is a predominant view that certain factors increase both the likelihood of telecommuting and the frequency of telecommuting. These factors are having children in the household, being female, having more education, having a longer commute trip, having worked longer for one's current employer and/or in one's current position, and having a job that does not require face-to-face contact with coworkers or clients. Most studies of VMT and trip reductions from telecommuting show that telecommuters significantly reduce both daily trips and VMT. Not only does commute VMT fall, but noncommute VMT appears to fall in some cases as well. The studies of VMT, however, tend to focus on the reductions for individual employees who choose to telecommute. Although an individual telecommuter may experience a sharp reduction in VMT, total benefits depend on how many people are telecommuting, how often they are doing so, and the duration of telecommuting. More research is needed with larger and more broadly based datasets across employers that include both individual employee characteristics and employer and job characteristics. This would allow a better analysis of telecommuting choice and frequency as well as more reliable estimates of VMT and emissions impacts. This discussion paper is one in a series of four RFF papers on telecommuting published in December 2004. Discussion papers 04-42 and 04-43 present analyses of two recent datasets on telecommuters. In 04-42, Nelson and Walls analyze data from five pilot cities enrolled in the "ecommute" program. In 04-43, Safirova and Walls analyze data from a broad survey conducted by the Southern California Association of Governments (SCAG) of telecommuters and nontelecommuters. Finally, in 04-45 Nelson presents an assessment of institutional and regulatory barriers to using telecommuting in a mobile source emissions trading program. The studies by RFF are part of a larger report on the ecommute program completed by the Global Environment and Technology Foundation (GETF) for the U.S. Environmental Protection Agency.

description: Satellite quantum communications are emerging within the panorama of quantum technologies as a more effective strategy to distribute completely-secure keys at very long distances, therefore playing an important role in the architecture of a large-scale quantum network. In this work, we apply and extend recent results in free-space quantum communications to determine the ultimate limits at which secret (and entanglement) bits can be distributed via satellites. Our study is comprehensive of the various practical scenarios, encompassing both downlink and uplink configurations, with satellites at different altitudes and zenith angles. It includes effects of diffraction, extinction, background noise and fading, due to pointing errors and atmospheric turbulence (appropriately developed for slant distances). Besides identifying upper bounds, we also discuss lower bounds, i.e., achievable rates for key generation and entanglement distribution. In particular, we study the composable finite-size secret key rates that are achievable by protocols of continuous variable quantum key distribution, for both downlink and uplink, showing the feasibility of this approach for all configurations. Finally, we present a study with a sun-synchronous satellite, showing that its key distribution rate is able to outperform a ground chain of ideal quantum repeaters.

Nearing Extremal Intersecting Giants and New Decoupled Sectors in N = 4 SYM

description: We study near-horizon limits of near-extremal charged black hole solutions to five-dimensional $U(1)^3$ gauged supergravity carrying two charges, extending the recent work of Balasubramanian et.al. We show that there are two near-horizon decoupling limits for the near-extremal black holes, one corresponding to the near-BPS case and the other for the far from BPS case. Both of these limits are only defined on the 10d IIB uplift of the 5d black holes, resulting in a decoupled geometry with a six-dimensional part (conformal to) a rotating BTZ X $S^3$. We study various aspects of these decoupling limits both from the gravity side and the dual field theory side. For the latter we argue that there should be two different, but equivalent, dual gauge theory descriptions, one in terms of the 2d CFT's dual to the rotating BTZ and the other as certain large R-charge sectors of d=4,N =4 U(N) SYM theory. We discuss new BMN-type sectors of the N=4 SYM in the $N\to\infty$ limit in which the engineering dimensions scale as $N^{3/2}$ (for the near-BPS case) and as $N^2$ (for the far from BPS case).

Impact of the higher twist effects on the $γγ^{*} \to π^{0}$ transition form factor

description: We reanalyze the $γγ^{*} \to π^{0}$ transition form factor $F_{πγ}(Q^2)$ within the QCD light-cone sum rules method with the twist-4 accuracy. In computations the pion leading twist distribution amplitude (DA) with two nonasymptotic terms, and the renormalon method-inspired twist-4 DAs are used. The latters allow us to estimate impact of effects due to higher conformal spin components in the pion twist-4 DAs on the form factor $F_{πγ}(Q^2)$. Obtained theoretical predictions are employed to deduce constraints on the pion DAs from CELLO and CLEO data.

SiMPLISTIC: A Novel Pairwise Potential for Implicit Solvent Lipid Simulations with Single-site Models

description: Implicit solvent, coarse-grained models with pairwise interactions can access the largest length and time scales in molecular dynamics simulations, owing to the absence of interactions with a huge number of solvent particles, the smaller number of interaction sites in the model molecules, and the lack of fast sub-molecular degrees of freedom. In this paper, we describe a maximally coarse-grained model for lipids in implicit water. The model is called SiMPLISTIC, which abbreviates for Single-site Model with Pairwise interaction for Lipids in Implicit Solvent with Tuneable Intrinsic Curvature. SiMPLISTIC lipids rapidly self-assemble into realistic non-lamellar and lamellar phases such as inverted micelles and bilayers, the spontaneous curvature of the phase being determined by a single free parameter of the model. Model membrane simulations with the lamellar lipids show satisfactory fluid and gel phases with no interdigitation or tilt. The model lipids follow rigid body dynamics suggested by empirical studies, and generate bilayer elastic properties consistent with experiments and other simulations. SiMPLISTIC can also simulate mixtures of lipids that differ in their packing parameter or length, the latter leading to the phenomenon of hydrophobic mismatch driven domain formation. The model has a large scope due to its speed, conceptual and computational simplicity, and versatility. Applications may range from large-scale simulations for academic and industrial research on various lipid-based systems, such as lyotropic liquid crystals, biological and biomimetic membranes, vectors for drug and gene delivery, to fast, lightweight, interactive simulations for gaining insights into self-assembly, lipid polymorphism, biomembrane organization etc.

The AHI : an audio and haptic interface for simulating contact interactions
Creators: name: DiFilippo, Derek
Publisher: name: University of British Columbia
Year: 2009

description: A contact interaction occurs when two rigid objects strike, scrape, or slide against one another. Auditory and haptic (touch) feedback from contact interactions can provide useful information to an individual about their world. We have implemented a prototype human-computer interface that renders synchronized auditory and haptic contact interactions with very low (1ms) latency. This audio and haptic interface (AHI) includes a Pantograph haptic device that reads position input from a user and renders force output based on this input. We synthesize audio in real-time by convolving the force profile generated by user interaction with the measured audio impulse response of the real-world version of the virtual surface. The resulting auditory and haptic stimuli are tightly coupled because we produce both using the same force profile. Also, because we use a dedicated DSP for haptic control and audio synthesis we are able to achieve negligible system latency. The AHI is the only human-computer interface that we know of for providing closely coupled auditory and haptic stimuli with guaranteed low latency. Our work with the AHI draws on research results from a variety of fields: in haptics, audio synthesis, robotic measurement, and psychophysics. We have conducted a pilot user study with the AHI to verify that the system latency lies below the perceptual threshold for detecting synchronization between auditory and haptic contact events. We have also presented our work as a live demonstration at an international conference and have taken some preliminary steps toward integrating the AHI with a rigid body dynamic simulation. These three separate evaluations suggest that the AHI device and algorithms could prove valuable for further perceptual studies and for synthesizing continuous contact interactions in more general virtual environments with commercial haptic devices.
Momentum spectra of charmonium produced in a quark-gluon plasma

description: We calculate rapidity and transverse momentum distributions of charmonium formed in high energy heavy ion collsions from incoherent recombination of charm quarks. The results are very sensitive to the corresponding distributions of the charm quarks, and thus can serve as a probe of the state of matter produced in the heavy ion collision. At one extreme we generate a set of charm pair momenta directly from pQCD amplitudes, which are appropriate if one can neglect interaction of the quarks with the medium. At the other extreme we generate momenta of charm quarks in thermal equilibrium with the expanding medium, appropriate for an extremely strong interaction. Explicit predictions are made for J/Psi formation in Au-Au interactions at RHIC. We find that for the case in which charm quark momenta are unchanged from the pQCD production calculation, both the rapidity and transverse momentum spectra of the formed J/Psi are substantially narrower than would be anticipated in scenarios which do not include the in-medium formation. In particular, the average transverse momentum of the J/Psi will exhibit a non-monotonic behavior in the progression from p-p to p-A to A-A interactions.
