description: Spectrophotometric observations at high signal-to-noise ratio were obtained of a complete sample of 347 DA white dwarfs from the Palomar Green (PG) Survey. Fits of observed Balmer lines to synthetic spectra calculated from pure-hydrogen model atmospheres were used to obtain robust values of Teff, log g, masses, radii, and cooling ages. The luminosity function of the sample, weighted by 1/Vmax, was obtained and compared with other determinations. The mass distribution of the white dwarfs is derived, after important corrections for the radii of the white dwarfs in this magnitude-limited survey and for the cooling time scales. The formation rate of DA white dwarfs from the PG is estimated to be 0.6x10^(-12) pc^(-3) yr^(-1). Comparison with predictions from a theoretical study of the white dwarf formation rate for single stars indicates that >80% of the high mass component requires a different origin, presumably mergers of lower mass double degenerate stars. In order to estimate the recent formation rate of all white dwarfs in the local Galactic disk, corrections for incompleteness of the PG, addition of the DB-DO white dwarfs, and allowance for stars hidden by luminous binary companions had to be applied to enhance the rate. An overall formation rate of white dwarfs recently in the local Galactic disk of 1.15+/-0.25x10^(-12) pc^(-3) yr^(-1) is obtained. Two recent studies of samples of nearby Galactic planetary nebulae lead to estimates around twice as high. Difficulties in reconciling these determinations are discussed.

description: To study the dynamic seismic responses of buried socketed high-density polyethylene (HDPE) pipes in sandy soil foundations during seismic excitations, pipe acceleration, pipe strain and displacement response data were obtained via indoor scaling tests and FLAC3D numerical simulations to establish a socketed HDPE pipe model. The numerical simulation results were compared with the experimental data to validate the effectiveness of the model. A large-diameter HDPE pipe model was established to simulate actual engineering situations. The difference in the seismic liquefaction response between socketed pipes and nonsocketed pipes was systematically analysed. The mechanical responses of socketed pipes were determined via numerical simulations. Compared with those of straight pipes, the acceleration response and strain of socketed HDPE pipes undergo greater changes, whereas the displacement of straight pipes is greater. The peak strain of the socketed pipe decreases axially from the centre to the ends, with the maximum strain occurring at the pipe centre and the minimum strain occurring at the pipe ends, and the peak strain in the middle of the pipe is more than 4 times greater than that at the ends of the pipe. The peak acceleration of the socketed pipes and its range both increase with increases in the input acceleration peak. The displacement of the socketed pipes increases with increases in the input acceleration peak and the depth of the pipeline, and it decreases with increases in the relative density of the soil body and the diameter of the pipe. In the numerical analysis, different diameters were simulated many times, and an equation for the axial strain and displacement of a pipeline with changes in the pipeline diameter is proposed. At a given burial depth, the socketed pipe strain decreases with increasing pipe diameter, whereas the pipeline displacement increases. For a given pipe diameter, both the strain and displacement of a socketed pipe increase with increasing burial depth.

description: We explicitly construct a solution of eight-dimensional gauged supergravity representing D6-branes wrapped on six-cycles inside Calabi-Yau fourfolds. The solution preserves two supercharges and asymptotically is a cone with the coset space SU(2)^4/U(1)^3 as its base. It is shown to correspond to an M-theory compactification on a Calabi-Yau manifold with SU(5) holonomy and we discuss in detail its geometrical and topological features. We also construct a family of related higher dimensional metrics having SU(n+1) holonomy, which of course have no brane interpretation.

description: Transporting nu_mu and nu_tau in a supernova (SN) core involves several processes that have been neglected in traditional simulations. Based on a Monte Carlo study we find that the flavor-dependent spectral differences are much smaller than is often stated in the literature. A full-scale SN simulation using a Boltzmann solver and including all relevant neutrino reactions confirms these results. The flavor-dependent flux differences are largest during the initial accretion phase.

description: Mapping the molecular gas content of the universe is key to our understanding of the build-up of galaxies over cosmic time. Spectral line scans in deep fields, such as the Hubble Ultra Deep Field (HUDF), provide a unique view on the cold gas content out to high redshift. By conducting `spectroscopy-of-everything', these flux-limited observations are sensitive to the molecular gas in galaxies without preselection, revealing the cold gas content of galaxies that would not be selected in traditional studies. In order to capitalize on the molecular gas observations, knowledge about the physical conditions of the galaxies detected in molecular gas, such as their interstellar medium conditions, is key. Fortunately, deep surveys with integral-field spectrographs are providing an unprecedented view of the galaxy population, providing redshifts and measurements of restframe UV/optical lines for thousands of galaxies. We present the results from the synergy between the ALMA Spectroscopic Survey of the HUDF (ASPECS), with deep integral field spectroscopy from the MUSE HUDF survey and multi-wavelength data. We discuss the nature of the galaxies detected in molecular gas without preselection and their physical properties, such as star formation rate and metallicity. We show how the combination of ALMA and MUSE integral field spectroscopy can constrain the physical properties in galaxies located around the main sequence during the peak of galaxy formation.

description: In this paper, a cooperative spectrum sensing scheme based on compressive sensing is proposed. In this scheme, secondary users (SUs) are organized in clusters. In each cluster, SUs forward their compressed signals to the cluster head. Then, the cluster heads report the local sensing data to the fusion center to make the final decision. Analog to information converter is adopted to acquire the received SUs signals. The proposed scheme is evaluated using several metrics, including probability of detection, compression ratio, probability of error, and processing time. The simulation results are compared with those of other cooperative sensing schemes. With our proposed scheme, cooperative spectrum sensing achieves a high probability of detection of 97%, a processing time of 2ms, a low compression ratio of 10%, and low error rate of 35 %. These results show that our proposed method outperforms the spectrum sensing without compressive sensing.

In order to establish the functional form of the volume dependence we study systematically the finite-size effects in the light hadron spectrum. We give an update on the status of the GRAL project and show that our simulation data for the light hadron masses depend exponentially on the lattice size.

Oltre 6 miliardi di anni fa, le regioni periferiche della Via Lattea erano le più sicure per lo sviluppo di eventuali forme di vita, al riparo dalle esplosioni più violente dell’universo. Lo dimostra un nuovo studio che ha analizzato l’incidenza di questi eventi nel corso dell’evoluzione della nostra galassia. Con il passare del tempo, da 4 miliardi di anni fa in avanti, regioni più centrali – compresa quella che ospita il Sistema solare – diventano le più sicure. Non troppo però: lo studio avvalora anche l’ipotesi che la prima delle cinque grandi estinzioni di massa sulla Terra, 445 milioni di anni fa, sia stata provocata proprio da un lampo gamma

description: The day seems not too far away, in which robots will be an active part of our daily life, just like electric appliances already are. Hence, there is an increasing need for paradigms, tools, and techniques to design proper human-robot interaction in a human-centered fashion (Beckerle et al., 2017). To this end, appropriate Human-Machine Interfaces (HMIs) are required, and there is a growing body of research showing how the Peripheral Nervous System (PNS) might be the ideal channel through which this interaction could proficiently happen.

description: We discuss constraints on soft CP-violating couplings of axion-like particles with photon and fermions by using data on electric dipole moments of Standard Model particles. In particular, for the ALP leptophilic scenario we derive bounds on CP-odd ALP-photon-photon coupling from data of the {\tt ACME} Collaboration on electron EDM. We also discuss prospects of the Storage Ring experiment to constrain the ALP-photon-photon coupling from data on proton EDM for the simplified hadrophilic interactions of ALP. The regarding constraints from experimental bounds on the muon and neutron EDMs are weak. We set constraint on the CP-odd ALP coupling with electron and derive bounds on combinations of coupling constants, which involve soft CP-violating terms.

description: We have performed detailed population synthesis on a large number (20 million) of binary systems in order to investigate the properties of massive double degenerate binaries. We have included new important results in our input physics in order to obtain more reliable estimates of the merging timescales and relative formation rates. These improvements include refined treatment of the binding energy in a common envelope, helium star evolution and reduced kicks imparted to newborn black holes. The discovery and observations of GRB afterglows and the identification of host galaxies have allowed comparisons of theoretical distributions of merger sites with the observed distribution of afterglow positions relative to host galaxies. To help investigate the physical nature of short- and long-duration GRBs, we compute the distances of merging neutron stars (NS) and/or black holes (BH) from the centers of their host galaxies, as predicted by their formation scenario combined with motion in galactic potentials. Furthermore, we estimate the formation rate and merging rate of these massive double degenerate binaries. The latter is very important for the prospects of detecting gravitational waves with LIGO/VIRGO. We find that the expected detection rate for LIGO II is ~850 per year for galactic field sources and that this rate is completely dominated by merging BHBH binaries. Even LIGO I may detect such an event (~0.25 per year). Our preferred model estimate the Galactic field NSNS merger rate to be ~1.5*10^(-6) per year. For BHBH systems this model predicts a merger rate of ~9.7*10^{-6} per year. Our studies also reveal an accumulating numerous population of very wide orbit BHBH systems which never merge (t >> t_Hubble).

description: Giant impacts dominate the final stages of terrestrial planet formation and set the configuration and compositions of the final system of planets. A giant impact is believed to be responsible for the formation of Earth's Moon, but the specific impact parameters are under debate. Because the canonical Moon-forming impact is the most intensely studied scenario, it is often considered the archetypal giant impact. However, a wide range of impacts with different outcomes are possible. Here we examine the total energy budgets of giant impacts that form Earth-mass bodies and find that they differ substantially across the wide range of possible Moon-forming events. We show that gravitational potential energy exchange is important, and we determine the regime in which potential energy has a significant effect on the collision outcome. Energy is deposited heterogeneously within the colliding planets, increasing their internal energies, and portions of each body attain sufficient entropy for vaporization. After gravitational re-equilibration, post-impact bodies are strongly thermally stratified, with varying amounts of vaporized and supercritical mantle. The canonical Moon-forming impact is a relatively low energy event and should not be considered the archetype of accretionary giant impacts that form Earth-mass planets. After a giant impact, bodies are significantly inflated in size compared to condensed planets of the same mass, and there are substantial differences in the magnitudes of their potential, kinetic and internal energy components. As a result, the conditions for metal-silicate equilibration and the subsequent evolution of the planet may vary widely between different impact scenarios.

description: An unexpected finding two decades ago demonstrated that Shockley electron states in noble metal surfaces are spin-polarized, forming a circulating spin texture in reciprocal space. The fundamental role played by the spin degree of freedom was then revealed, even for a non-magnetic system, whenever the spin-orbit coupling was present with some strength. Here we demonstrate that similarly to electrons in the presence of spin-orbit coupling, the propagating vibrational modes are also accompanied by a well-defined magnetic oscillation even in non-magnetic materials. Although this effect is illustrated by considering a single layer of the WSe2 dichalogenide, the phenomenon is completely general and valid for any non-magnetic material with spin-orbit coupling. The emerging phonon-induced magnetic oscillation acts as an additional effective flipping mechanism for the electron spin and its implications in the transport and scattering properties of the material are evident and profound.

Towards a Coherent Theory of Physics and Mathematics: The Theory-Experiment Connection

Publisher: name: arXiv
Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The problem of how mathematics and physics are related at a foundational level is of much interest. One approach is to work towards a coherent theory of physics and mathematics together. Here steps are taken in this direction by first examining the theory experiment connection. The role of an implied theory hierarchy and use of computers in comparing theory and experiment is described. The main idea of the paper is to tighten the theory experiment connection by bringing physical theories, as mathematical structures over C, the complex numbers, closer to what is actually done in experimental measurements and computations. The method replaces C by C_{n} which is the set of pairs, R_{n},I_{n}, of n figure rational numbers in some basis. The properties of these numbers are based on the type of numbers that represent measurement outcomes for continuous variables. A model of space and time based on R_{n} is discussed. The model is scale invariant with regions of constant step size interrupted by exponential jumps. A method of taking the limit n to infinity to obtain locally flat continuum based space and time is outlined. Possibly the most interesting result is that R_{n} based space is invariant under scale transformations which correspond to expansion and contraction of space relative to a flat background. Also the location of the origin, which is a space and time singularity, does not change under these transformations. Some properties of quantum mechanics based on C_{n} and on R_{n} space are briefly investigated.

Liminal Space: The Transient Experience of the Architecturally Obsolete
Creators: name: Ginter-Agreda, Julio
Publisher: name: The University of British Columbia
Year: 2024

description: This project explores the concept of liminal space as understood within a cultural continuum of the Internet and the Digital Age. The first part closely examines the online memetic origins of liminal space pictures and theorizations of the uncanny. Given its proliferation on image boards and social media as an architectural mode of analyzing space, what follows is a detailed analysis of both the architecture of the spaces themselves and the architecture of the pictures which capture them. The second part examines the present-day zeitgeist around liminal space and its intentional spread through various mainstream forms, such as television series and videogames, and its unintentional spread within architectural practice. The goal is to establish a rigorous framework to conceptualize liminality not only as a retrospective form of analysis, but as a forward-thinking research lens which focuses on the obsolescence of space and picture as indications of contemporary architectural practice.

description: The coupling constant dependence of correlation functions of BPS operators in N=4 Yang-Mills can be expressed in terms of integrated correlation functions. We approximate these integrated correlators by using a truncated OPE expansion. This leads to differential equations for the coupling dependence. When applied to a particular sixteen point correlator, the coupling dependence we find agrees with the corresponding amplitude computed via the AdS/CFT correspondence. We conjecture that this truncation becomes exact in the large N and large 't Hooft coupling limit.

description: We revisit certain natural algebraic transformations on the space of 3D topological quantum field theories (TQFTs) called "Galois conjugations." Using a notion of multiboundary entanglement entropy (MEE) defined for TQFTs on compact 3-manifolds with disjoint boundaries, we give these abstract transformations additional physical meaning. In the process, we prove a theorem on the invariance of MEE along orbits of the Galois action in the case of arbitrary Abelian theories defined on any link complement in $S^3$. We then give a generalization to non-Abelian TQFTs living on certain infinite classes of torus link complements. Along the way, we find an interplay between the modular data of non-Abelian TQFTs, the topology of the ambient spacetime, and the Galois action. These results are suggestive of a deeper connection between entanglement and fusion.

description: The effect of the finite system size on the QCD phase diagram was studied with various momentum space constraints within a mean-field quark-meson model. On the one hand side, the choice of the scenario -- low-momentum cutoff and discretization with periodic or antiperiodic boundary conditions -- and the presence of the vacuum fluctuations were found to strongly affect the volume dependence of the CEP. On the other hand, its location is significantly shifted in each case for linear sizes below $L\approx 10$ fm. This is also reflected in the conserved charge fluctuations, which were investigated along the phase boundary using multiple scenarios for the finite size effects.

description: This thesis presents measurements of low-energy positron scattering from the noble gases. Sets of total cross section measurements are presented for Ne-Xe, and are compared with prior experimental and theoretical results. The present results represent a substantial improvement on previous experiments, due to improved statistical and systematic uncertainty, as well as an energy resolution that is better than that achieved in most other experiments. Methods for calculating cross sections in a strong magnetic field are discussed, along with improvements made to the techniques for analysis, and the handling and correction, or minimisation, of systematic errors. Preliminary tests of the application of effective range theory have been conducted using theoretical total cross sections, calculated in the polarized orbital approach. These tests provide estimates of the range of applicability of effective range theory. Using this knowledge, analysis of the low-energy cross section, for energies below about 5 eV, has been carried out, using effective range theory to extract the s-wave scattering length. This work is in preparation for future measurements of low-energy total cross sections from metal vapours, where knowledge of the scattering length will provide a means of inferring the presence of theoretically predicted positron-atom bound states. Measurements of the elastic total cross section for positron scattering from He-Xe, in the region of the Ps formation threshold, are presented. These results indicate the presence of pronounced Wigner cusps in each cross section, resulting from channel coupling between the elastic and Ps formation scattering channels. These measurements are compared and contrasted with other recent experimental measurements. The trend of the channel coupling behaviour is discussed with respect to theoretical predictions.

 Munidopsis aries.— Gore, 1983: 203, fig. 2 (synonymy and references).— Macpherson & Segonzac, 2005: 15, fig. 3.
 Material examined. Reunion Island, MD32, Stn 19, 3180– 3480 m: 1 F 69.1 mm (MNHN-Ga5503).
 Remarks. The specimen agrees quite well with the material from the Atlantic Ocean (Macpherson & Segonzac 2005). The species, as the with the closest relative M. albatrossae Pequegnat & Pequegnat, 1973, from the eastern Pacific, has a denticulate carina on the distolateral margin of the fixed finger of P1 (incorrectly stated as absent in Macpherson & Segonzac 2005).
 Distribution. This species was previously known from the Atlantic Ocean: Bequia (Caribbean Sea) at 2912 m (A. Milne-Edwards 1880), Azores Islands, (as M. sundi, Sivertsen & Holthuis 1956), Middle Atlantic Bight (Wenner 1982), Colombia and Venezuela Basins and Gulf of Mexico (Pequegnat & Pequegnat 1971, Gore 1983), between 2615 and 4095 m, and Iberian Abyssal Plain, Mauritania, Angola and South Africa, between 3130 and 5320 m (Macpherson & Segonzac 2005). The present material extends the distribution to the southwest Indian Ocean.

description: The satellite experiment WMAP has produced for the first time a high-coverage, high resolution survey of the microwave sky, releasing publicly available data that are likely to remain unrivalled for years to come. Here we compare the WMAP temperature power spectrum, along with an exhautive compilation of previous experiments, to models of dark energy that allow for a tracking epoch at the present, deriving updated bounds on the dark energy equation of state and the other cosmological parameters. Moreover, we complement the analysis by including a coupling of the dark energy to dark matter. The main results are: a) the WMAP data alone constrains the equation of state of tracking dark energy to be w_ϕ-1), which implies for an inverse power law potential an exponent α<0.99(2.08); b) the dimensionless coupling to dark matter is |β|<0.07(0.13). Including the results from the supernovae Ia further constrains the dark energy equation of state.

description: We present ground-based 2.1 to 4.2 microns observations of four low-mass protostars. We searched for the 4.1 microns OD stretch band, characteristic of solid HDO in grain mantles. We did not detect solid HDO in any of the four sources, but we derive 3-sigma upper limits from 0.5% to 2% for the HDO/H2O ratio depending on the source. These ratios provide strong constraints to solid-state deuteration models when compared to deuterium fractionation values observed in the gas phase. We discuss various scenarios that could lead to such a low water deuteration compared to the high formaldehyde and methanol deuteration observed in the gas phase.

description: Nuclear Magnetic Resonance (NMR) is one of the most powerful experimental techniques to characterize the structure of molecules and confined liquids. Nevertheless, the complexity of the systems under investigation usually requires complementary computational studies to interpret the NMR results. In this work we focus on polycyclic aromatic hydrocarbons (PAHs), an important class of organic molecules which have been commonly used as simple analogues for the spectroscopic properties of more complex systems, such as porous disordered carbons. We use Density Functional Theory (DFT) to calculate 13C chemical shifts and Nucleus Independent Chemical Shifts (NICS) for 34 PAHs. The results show a clear molecular size dependence of the two quantities, as well as the convergence of the 13C NMR shifts towards the values observed for graphene. We then present two computationally cheap models for the prediction of NICS in simple PAHs. We show that while a simple dipolar model fails to produce accurate values, a perturbative tight-binding approach can be successfully applied for the prediction of NICS in this series of molecules, including some non-planar ones containing 5- and 7-membered rings. This model, one to two orders of magnitudes faster than DFT calculations, is very promising and can be further refined in order to study more complex systems.
