description: We describe a procedure for the numerical simulation of the planetary nebulae luminosity function (PNLF), improving on previous work (Mendez & Soffner 1997). Earlier PNLF simulations were based on an imitation of the observed distribution of the intensities of [O III] 5007 relative to Hbeta, generated predominantly using random numbers. We are now able to replace this by a distribution derived from the predictions of hydrodynamical PN models (Schoenberner et al. 2007), which are made to evolve as the central star moves across the HR diagram, using proper initial and boundary conditions. In this way we move one step closer to a physically consistent procedure for the generation of a PNLF. As an example of these new simulations, we have been able to reproduce the observed PNLF in the Small Magellanic Cloud.

description: We present the main sequence for all galaxies and star-forming galaxies for a sample of 28,469 massive ($M_\star \ge 10^{11}$M$_\odot$) galaxies at cosmic noon ($1.5 < z < 3.0$), uniformly selected from a 17.5 deg$^2$ area (0.33 Gpc$^3$ comoving volume at these redshifts). Our large sample allows for a novel approach to investigating the galaxy main sequence that has not been accessible to previous studies. We measure the main sequence in small mass bins in the SFR-M$_{\star}$ plane without assuming a functional form for the main sequence. With a large sample of galaxies in each mass bin, we isolate star-forming galaxies by locating the transition between the star-forming and green valley populations in the SFR-M$_{\star}$ plane. This approach eliminates the need for arbitrarily defined fixed cutoffs when isolating the star-forming galaxy population, which often biases measurements of the scatter around the star-forming galaxy main sequence. We find that the main sequence for all galaxies becomes increasingly flat towards present day at the high-mass end, while the star-forming galaxy main sequence does not. We attribute this difference to the increasing fraction of the collective green valley and quiescent galaxy population from $z=3.0$ to $z=1.5$. Additionally, we measure the total scatter around the star-forming galaxy main sequence and find that it is $\sim0.5-1.0$ dex with little evolution as a function of mass or redshift. We discuss the implications that these results have for pinpointing the physical processes driving massive galaxy evolution.

description: We create new U, B, V, R and I-band light curve templates of type Ia Supernovae (SNe Ia) and re-analyze 122 nearby (redshift < 0.11) SNe Ia using a new ``Multi-band Stretch method,'' which is a revised Stretch method (cf. Perlmutter et al. 1997; Goldhaber et al. 2001) extended to five bands. We find (i) our I-band template can fit about 90% of SNe Ia I-band light curves, (ii) relationships between luminosity, colours and stretch factors, (iii) possible sub-groups of SNe Ia, and (iv) the ratio of total to selective extinction R in other galaxies can be consistent with that in the Milky Way under the assumption that SNe Ia have diversity in their intrinsic colour. Based on these results, we discuss how to select subsets of SNe Ia to serve as good distance indicators for cosmology. We find two possibilities: one is to choose ``BV bluest'' (-0.14 < (B-V)_{max} <= -0.10) objects and the other is to use only SNe Ia which occur in E or S0 galaxies. Within these subsets, we find the root mean square (r.m.s.) of peak B-band magnitudes is 0.17 mag (``BV bluest'' sample) and 0.12 mag (E or S0 sample).

Population III star formation in a Lambda CDM universe, II: Effects of a photodissociating background

description: We examine aspects of primordial star formation in the presence of a molecular hydrogen-dissociating ultraviolet background. We compare a set of AMR hydrodynamic cosmological simulations using a single cosmological realization but with a range of ultraviolet background strengths in the Lyman-Werner band. This allows us to study the effects of Lyman-Werner radiation on suppressing H2 cooling at low densities as well as the high-density evolution of the collapsing core in a self-consistent cosmological framework. We find that the addition of a photodissociating background results in a delay of the collapse of high density gas at the center of the most massive halo in the simulation and, as a result, an increase in the virial mass of this halo at the onset of baryon collapse. We find that, contrary to previous results, Population III star formation is not suppressed for J$_{21} \geq 0.1$, but occurs even with backgrounds as high as J$_{21} = 1$. We find that H2 cooling leads to collapse despite the depressed core molecular hydrogen fractions due to the elevated H2 cooling rates at $T=2-5 \times 10^3$ K. We observe a relationship between the strength of the photodissociating background and the rate of accretion onto the evolving protostellar cloud core, with higher LW background fluxes resulting in higher accretion rates. Finally, we find that the collapsing halo cores in our simulations do not fragment at densities below $n \sim 10^{10}$ cm$^{-3}$ regardless of the strength of the LW background, suggesting that Population III stars forming in halos with T$_{vir} \sim 10^4$ K may still form in isolation.

description: Early in his life Pasolini showed interest in Dante: in a letter sent to Luciano Serra in 1945, he declared that ‘la questione di Dante è importantissima’. He later reaffirmed his interest in Dante in two attempts to rewrite the Commedia: La Mortaccia and La Divina Mimesis. La Mortaccia is an unfinished text from 1959 written as free indirect speech in Roman dialect, in which the author tells the story of a prostitute. Walking at night along the Via Tiburtina, she meets three ‘canacci lupi’, which she tries in vain to escape. Eventually Dante comes to her rescue and takes her to the Rebibbia jail. But by 1963, Pasolini had already left behind the project of La Mortaccia and its linguistic perspective, dependent on the legacy of the fifties. In that year he mentioned La Divina Mimesis for the first time. In the seventh section of Poesia in forma di rosa (‘Progetto di opere future’), it is described as ‘opera, se mai ve ne fu, da farsi’: […]

Fundamental properties of stars from Kepler and Gaia data: parallax offset and revised scaling relations

description: Data from the space missions {\it Gaia}, {\it Kepler}, {\it CoRoT} and {\it TESS}, make it possible to compare parallax and asteroseismic distances. From the ratio of two densities $ρ_{\rm sca}/ρ_π$, we obtain an empirical relation $f_{Δν}$ between the asteroseismic large frequency separation and mean density, which is important for more accurate stellar mass and radius. This expression for main-sequence (MS) and subgiant stars with $K$-band magnitude is very close to the one obtained from interior MS models by Yıldız, Çelik \& Kayhan. We also discuss the effects of effective temperature and parallax offset as the source of the difference between asteroseismic and non-asteroseismic stellar parameters. We have obtained our best results for about 3500 red giants (RGs) by using 2MASS data and model values for $f_{Δν}$ from Sharma et al. Another unknown scaling parameter $f_{ν_{\rm max}}$ comes from the relationship between the frequency of maximum amplitude and gravity. Using different combinations of $f_{ν_{\rm max}}$ and the parallax offset, we find that the parallax offset is generally a function of distance. The situation where this slope disappears is accepted as the most reasonable solution. By a very careful comparison of asteroseismic and non-asteroseismic parameters, we obtain very precise values for the parallax offset and $f_{ν_{\rm max}}$ for RGs of $-0.0463\pm0.0007$ mas and $1.003\pm0.001$, respectively. Our results for mass and radius are in perfect agreement with those of APOKASC-2: the mass and radius of $\sim$3500 RGs are in the range of about 0.8-1.8 M$_{\odot}$ (96 per cent) and 3.8-38 R$_{\odot}$, respectively.

Het is een self-assessment tool waarbij is gekeken naar hoe FAIR-enabled de betreffende HBO instellingen zijn. In deze presentatie zijn de resultaten van de survey voor HBO instellingen op basis van de Do I-PASS for FAIR – Self Assessment tool te vinden. Dit rapport biedt een weergave van de volwassenheid van het werken volgens de FAIR- principes binnen het HBO. Het geeft handvatten aan het DCC-PO om focus aan te brengen in de belangrijkste knelpunten met betrekking tot het faciliteren van een ‘FAIR- enabled’ organisatie. Centraal staat; “Wat is de huidige status van de onderzoeksondersteuning bij het voldoen aan de FAIR principes binnen HBO instellingen? ” Ondersteunend personeel vanuit de deelnemende hogescholen aan het DCC-PO project is gevraagd om zelf, over hun eigen instelling, de status van FAIR adoptie in kaart te brengen aan de hand van een vragenlijst. Het aantal waarnemingen is echter onvoldoende om sluitende conclusies te kunnen trekken. De resultaten zijn dan ook indicatief. Er hebben 18 Hogescholen deelgenomen aan dit onderzoek, allen aangesloten bij het DCC-PO. Er is dan ook geen sprake van een representatieve steekproef van HBO instellingen, uitspraken in dit rapport betreffen dan ook enkel de deelnemende instellingen.

Time-dependent treatment of cosmic-ray spectral steepening due to turbulence driving

Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Cosmic-ray acceleration at non-relativistic shocks relies on scattering by turbulence that the cosmic rays drive upstream of the shock. We explore the rate of energy transfer from cosmic rays to non-resonant Bell modes and the spectral softening it implies. Accounting for the finite time available for turbulence driving at supernova-remnant shocks yields a smaller spectral impact than found earlier with steady-state considerations. Generally, for diffusion scaling with the Bohm rate by a factor $η$, the change in spectral index is at most $η$ divided by the Alfvénic Mach number of the thermal sub-shock. For $M_\mathrm{A}\lesssim 50$ it is well below this limit. Only for very fast shocks and very efficient cosmic-ray acceleration the change in spectral index may reach $0.1$. For standard SNR parameters it is negligible. Independent confirmation is derived by considering the synchrotron energy losses of electrons: if intense nonthermal multi-keV emission is produced, the energy loss, and hence the spectral steepening, is very small for hadronic cosmic rays that produce TeV-band gamma-ray emission.

description: The new measurement of the muon's anomalous magnetic moment released by the Muon g-2 experiment at Fermilab sets strong constraints on the properties of many new particles. Using an effective field theory approach to the interactions of higher-spin fields, we evaluate the contribution of an electrically neutral and colour singlet spin-3/2 fermion to $(g-2)_μ$ and derive the corresponding constraints on its mass and couplings. These constraints are then compared with the ones on spin-1/2 fermions, such as the vector-like leptons that are predicted by various extensions of the Standard Model, the excited leptons which appear in composite models, as well as the charginos and neutralinos of supersymmetric theories. Unlike these new spin-1/2 fermions, the spin-3/2 particles generate only small contributions to the muon anomalous magnetic moment.

description: Models are used in both Software Engineering (SE) and Artificial Intelligence (AI). SE models may specify the architecture at different levels of abstraction and for addressing different concerns at various stages of the software development life-cycle, from early conceptualization and design, to verification, implementation, testing and evolution. However, AI models may provide smart capabilities, such as prediction and decision-making support. For instance, in Machine Learning (ML), which is currently the most popular sub-discipline of AI, mathematical models may learn useful patterns in the observed data and can become capable of making predictions. The goal of this work is to create synergy by bringing models in the said communities together and proposing a holistic approach to model-driven software development for intelligent systems that require ML. We illustrate how software models can become capable of creating and dealing with ML models in a seamless manner. The main focus is on the domain of the Internet of Things (IoT), where both ML and model-driven SE play a key role. In the context of the need to take a Cyber-Physical System-of-Systems perspective of the targeted architecture, an integrated design environment for both SE and ML sub-systems would best support the optimization and overall efficiency of the implementation of the resulting system. In particular, we implement the proposed approach, called ML-Quadrat, based on ThingML, and validate it using a case study from the IoT domain, as well as through an empirical user evaluation. It transpires that the proposed approach is not only feasible, but may also contribute to the performance leap of software development for smart Cyber-Physical Systems (CPS) which are connected to the IoT, as well as an enhanced user experience of the practitioners who use the proposed modeling solution.

description: We measure the expansion of an ultracold plasma across the field lines of a uniform magnetic field. We image the ion distribution by extracting the ions with a high voltage pulse onto a position-sensitive detector. Early in the lifetime of the plasma ($< 20$ $μ$s), the size of the image is dominated by the time-of-flight Coulomb explosion of the dense ion cloud. For later times, we measure the 2-D Gaussian width of the ion image, obtaining the transverse expansion velocity as a function of magnetic field (up to 70 G). We observe that the expansion velocity scales as B$^{-1/2}$, explained by a nonlinear ambipolar diffusion model with anisotropic diffusion in two different directions.

description: The extremely large magnetoresistance (XMR) observed in many topologically nontrivial and trivial semimetals has attracted much attention in relation to its underlying physical mechanism. In this paper, by combining the band structure and Fermi surface (FS) calculations with the Hall resistivity and de Haas-Van Alphen (dHvA) oscillation measurements, we studied the anisotropy of magnetoresistance (MR) of ReO$_3$ with a simple cubic structure, an "ordinary" nonmagnetic metal considered previously. We found that ReO$_3$ exhibits almost all the characteristics of XMR semimetals: the nearly quadratic field dependence of MR, a field-induced upturn in resistivity followed by a plateau at low temperatures, high mobilities of charge carriers. It was found that for magnetic field \emph{H} applied along the \emph{c} axis, the MR exhibits an unsaturated \emph{H}$^{1.75}$ dependence, which was argued to arise from the complete carrier compensation supported by the Hall resistivity measurements. For \emph{H} applied along the direction of 15$^\circ$ relative to the \emph{c} axis, an unsaturated \emph{H}$^{1.90}$ dependence of MR up to 9.43~$\times$~$10^3$$\%$ at 10~K and 9~T was observed, which was explained by the existence of electron open orbits extending along the $k_{x}$ direction. Two mechanisms responsible for XMR observed usually in the semimetals occur also in the simple metal ReO$_3$ due to its peculiar FS (two closed electron pockets and one open electron pocket), once again indicating that the details of FS topology are a key factor for the observed XMR in materials.

We present analytic results for the cut-constructible parts of the leading colour contributions to the all-plus helicity configuration of the $t\bar{t}gg$ amplitude. Using a special choice for the helicity basis of the massive fermions we are able to obtain extremely compact analytic expressions. In particular we describe how one can fix the divergent contributions from tadpole and wave-function renormalisation using universal UV and IR behaviour.

description: We study the duality between JT gravity and the double-scaled matrix model including their respective deformations. For these deformed theories we relate the thermal partition function to the generating function of topological gravity correlators that are determined as solutions to the KdV hierarchy. We specialise to those deformations of JT gravity coupled to a gas of defects, which conforms with known results in the literature. We express the (asymptotic) thermal partition functions in a low temperature limit, in which non-perturbative corrections are suppressed and the thermal partition function becomes exact. In this limit we demonstrate that there is a Hawking-Page phase transition between connected and disconnected surfaces for this instance of JT gravity with a transition temperature affected by the presence of defects. Furthermore, the calculated spectral form factors show the qualitative behaviour expected for a Hawking-Page phase transition. The considered deformations cause the ramp to be shifted along the real time axis. Finally, we comment on recent results related to conical Weil-Petersson volumes and the analytic continuation to two-dimensional de Sitter space.

description: In this study, we analyse the inter-relationships between the Labrador Sea densities, the boundary currents, the AMOC and, more generally, the wider climate of the North Atlantic across an ensemble of climate models. The study mostly relies on the analysis of two 300-year long high-resolution coupled control simulations (with HadGEM3-GC2 and HiGEM, respectively), and is completed with an ensemble of CMIP5 preindustrial control experiments to assess the model dependence of the results.

We have characterised the main modes of Labrador Sea density (LSD) variability across these models. The leading EOF of LSD is reasonably consistent across the control experiments (i.e. HadGEM-GC2, HiGEM and CMIP5). All models show a fairly uniform vertical structure, with maximum positive density values near the surface that slowly decrease with depth. The associated Principal Components of Labrador Sea densities (PC1-LSD) is generally associated with multidecadal variability, and have enhanced variance between 12-30 years. There is also a good agreement on the density evolution in the ocean-only forced experiments; all depict an increase in the Labrador Sea densities from the 60s to the mid 90s, followed by a decreasing trend up to the present. These coherent Labrador Sea density changes are encouraging, but do not appear to translate to coherent changes in the AMOC strength in the forced historical runs. In the control experiments, decadal trends in PC1 do have a strong link with equivalent trends in the AMOC at 45°N, and to a lesser extent with the AMOC at 26°N (which tend to exhibit suppressed variability at interdecadal timescales). Interestingly, no link between PC1-LSD and AMOC at 26°N is observed when the Ekman transport signal is removed. The link with the AMOC at subpolar latitudes can be explained through an effect of LSDs on the western boundary currents. Indeed, PC1-LSD is tightly linked to the boundary densities at 45 and 57°N, but can show important discrepancies across models regarding the depths involved. Larger model discrepancies occur when extending the analysis to 35°N.

Encouragingly, all models support a link between the multi-decadal trends in PC1-LSD and the delayed trends (by 3 to 10 years) in upper ocean temperature in the Eastern Subpolar Gyre (ESPG T700). This is a consistent result regardless of the particular model representation of the PC1-LSD links with the AMOC indices and the boundary densities, further supporting the role of the LSDs and the AMOC on the recent cold blob and its associated climate impacts.

A comparative study of the record keeping practices of the Anglican, Baptist and United churches in British Columbia
Creators: name: Sweeney, Shelley Toni
Publisher: name: University of British Columbia

description: The report entitled Canadian Archives (1980) speaks of a future Canadian archival "system" in which archives of government, business, and institutions are to be bound together through networking. Although churches are to be a part of this system, the Report does not specify their role. Yet the professional world of both archivists and historians in Canada, the United States, and Britain, has been divided over the question of custody of religious archives. Whether the churches themselves are expected to care for their own archives or whether public archives are expected to take up systematic and regular acquisition of religious archives will seriously affect the role of churches in the future development of the Canadian archival system. This thesis then addresses the question of how best to go about preserving religious archives by studying in detail the record keeping attitudes and practices of the Anglican, Baptist, and United Churches in British Columbia. Through a survey of church government and archival programmes, we delve into the nature of the relationships between creator and record. As well as examining the record keeping practices of the three churches, the survey touches upon the policies of secular, public archives in British Columbia towards church archives. The thesis then analyzes the backgrounds of the churches in Europe and in early British Columbia in order to determine why discernible differences exist in the record keeping of the three denominations. In conclusion, the thesis notes that the attitudes and practices of churches with regards to their records are affected by their theology and organization. On the one hand, such fundamental determinants, it is argued, are not easily overcome by public archives which set out to collect religious archives. On the other, those churches which have mounted archival programmes demonstrate a networking capability that so far exceeds that of the secular archival world. In any case, church archives appear destined to play a vital role in any future systematization of Canadian archives.
Hermaphrodites & Reproduction Group Activity
Creators: name: Schneider, Brenda
Publisher: name: QUBES Educational Resources

description: Hermaphrodites & Reproduction Group Activity guides students in overcoming a common misconception about hermaphroditism and self-fertilization. Students explore definitions of meiosis and sexual reproduction, and apply these definitions to categorize an example of reproduction in banana slugs. Students then analyze the selection pressures of sexual reproduction further, and apply these selection pressures to understand several mechanisms that have evolved to prevent self-fertilization. This activity for General Biology courses involves (1) recalling prior knowledge about sexual vs. asexual reproduction, (2) a jigsaw activity to refresh understanding of meiosis and sexual reproduction, (3) a fill in the blank activity, (4) videos on the selection pressures for sexual reproduction and mechanisms in plants of preventing self-fertilization, and (5) an arrangement activity where students move the s-alleles genotypes into a diagram of self-incompatible plants.

description: In this paper we explore whether the quantum oscillation signals recently observed in ortho-II YBa$_2$Cu$_3$O$_{6.5}$ may be explained by conventional density functional band-structure theory. Our calculations show that the Fermi surface of YBa$_2$Cu$_3$O$_{6.5}$ is extremely sensitive to small shifts in the relative positions of the bands. With rigid band shifts of around 30 meV small tubular pockets of Fermi surface develop around the Y point in the Brillouin zone. The cross-sectional areas and band masses of the quantum oscillatory orbits on these pockets are close to those observed. The difference between the bandstructure of YBa$_2$Cu$_3$O$_{6.5}$ and YBa$_2$Cu$_4$O$_{8}$ are discussed.
Fossil AGN jets as ultra high energy particle accelerators

description: Remnants of AGN jets and their surrounding cocoons leave colossal magnetohydrodynamic (MHD) fossil structures storing total energies ~10^{60} erg. The original active galacic nucleus (AGN) may be dead but the fossil will retain its stable configuration resembling the reversed-field pinch (RFP) encountered in laboratory MHD experiments. In an RFP the longitudinal magnetic field changes direction at a critical distance from the axis, leading to magnetic re-connection there, and to slow decay of the large-scale RFP field. We show that this field decay induces large-scale electric fields which can accelerate cosmic rays with an E^{-2} power-law up to ultra-high energies with a cut-off depending on the fossil parameters. The cut-off is expected to be rigidity dependent, implying the observed composition would change from light to heavy close to the cut-off if one or two nearby AGN fossils dominate. Given that several percent of the universe's volume may house such slowly decaying structures, these fossils may even re-energize ultra-high energy cosmic rays from distant/old sources, offsetting the ``GZK-losses'' due to interactions with photons of the cosmic microwave background radiation and giving evidence of otherwise undetectable fossils. In this case the composition would remain light to the highest energies if distant sources or fossils dominated, but otherwise would be mixed. It is hoped the new generation of cosmic ray experiments such as the Pierre Auger Observatory and ultra-high energy neutrino telescopes such as ANITA and lunar Cherenkov experiments will clarify this.

What are the degrees of freedom in the partonic fluid at RHIC ?

description: Recent RHIC data show evidence of multiple hadron production mechanisms in heavy ion collisions compared to simple fragmentation in vacuum. I will review the measurements of collective flow, high momentum quenching, and two particle angular correlations to show that neither thermal production nor string fragmentation can describe the abundances, the angular distributions or the kinematic properties of all hadrons produced at RHIC. The proposed new hadronization mechanisms not only serve as evidence for a deconfined partonic phase of matter, but also for strong coupling of the degrees of freedom in the deconfined phase. I will point out a surprising lack of flavor dependence in these properties at RHIC, though, which might have to lead to further revisions of our understanding of the relevant degrees of freedom in the partonic phase and during the hadronization process.

description: Magnetic field-line reconnection is a universal plasma process responsible for the conversion of magnetic field energy to the plasma heating and charged particle acceleration. Solar flares and Earth's magnetospheric substorms are two most investigated dynamical systems where magnetic reconnection is believed to be responsible for global magnetic field reconfiguration and energization of plasma populations. Such a reconfiguration includes formation of a long-living current systems connecting the primary energy release region and cold dense conductive plasma of photosphere/ionosphere. In both flares and substorms the evolution of this current system correlates with formation and dynamics of energetic particle fluxes. Our study is focused on this similarity between flares and substorms. Using a wide range of datasets available for flare and substorm investigations, we compare qualitatively dynamics of currents and energetic particle fluxes for one flare and one substorm. We showed that there is a clear correlation between energetic particle bursts (associated with energy release due to magnetic reconnection) and magnetic field reconfiguration/formation of current system. We then discuss how datasets of in-situ measurements in the magnetospheric substorm can help in interpretation of datasets gathered for the solar flare.

description: The process pp -> top anti-top bottom anti-bottom + X represents a very important background reaction to searches at the LHC, in particular to top anti-top H production where the Higgs boson decays into a bottom anti-bottom pair. A successful analysis of top anti-top H at the LHC requires the knowledge of direct top anti-top bottom anti-bottom production at next-to-leading order in QCD. We take the first step in this direction upon calculating the next-to-leading-order QCD corrections to the subprocess initiated by quark anti-quark annihilation. We devote an appendix to the general issue of rational terms resulting from ultraviolet or infrared (soft or collinear) singularities within dimensional regularization. There we show that, for arbitrary processes, in the Feynman gauge, rational terms of infrared origin cancel in truncated one-loop diagrams and result only from trivial self-energy corrections.

description: Chemical names are an important class of Medical Subject Headings (MeSH) terms which are assigned to each article indexed at the National Library of Medicine (NLM). Correct identification of chemical names has significant impact in medical applications and helps scientists identify information to better understand the structure, usage and interactions of chemicals with other molecular entities, i.e. in drug development research.

Development of better tools is conditional on the availability of high quality datasets, and the creation and maintenance of chemical terminologies is a complex task. The Chemical project at NLM thus, aims to accomplish these goals:

	Develop a high quality chemical name entity corpus that is representative of the terminology in the scientific literature,
	Develop a high accuracy tagger able to extract chemical mentions, and link them to the appropriate MeSH identifiable term, both in the article abstracts and in the full text.
	Share both resources with the community

description: Existing near-eye display designs struggle to balance between multiple trade-offs such as form factor, weight, computational requirements, and battery life. These design trade-offs are major obstacles on the path towards an all-day usable near-eye display. In this work, we address these trade-offs by, paradoxically, \textit{removing the display} from near-eye displays. We present the beaming displays, a new type of near-eye display system that uses a projector and an all passive wearable headset. We modify an off-the-shelf projector with additional lenses. We install such a projector to the environment to beam images from a distance to a passive wearable headset. The beaming projection system tracks the current position of a wearable headset to project distortion-free images with correct perspectives. In our system, a wearable headset guides the beamed images to a user's retina, which are then perceived as an augmented scene within a user's field of view. In addition to providing the system design of the beaming display, we provide a physical prototype and show that the beaming display can provide resolutions as high as consumer-level near-eye displays. We also discuss the different aspects of the design space for our proposal.
