description: We investigate the prospects of future supernova searches to get meaningful constraints about the cosmic star formation history (CSFH) and the delay time of type Ia supernovae from star formation (tau_{Ia}), based only on supernova data. Here we parameterize the CSFH by two parameters, alpha and beta that are the evolutionary indices (proportional to (1+z)^{alpha, beta}) at z ~ 1, respectively, and quantitatively examined how well the three parameters (alpha, beta, and tau_{Ia}) can be constrained in ongoing and future supernova surveys. We found that the type classification of detected supernovae down to the magnitude of I_{AB} ~ 27 is essential, to get useful constraint on beta. The parameter tau_{Ia} can also be constrained within an accuracy of ~ 1--2 Gyr, without knowing alpha that is somewhat degenerate with tau_{Ia}. This might be potentially achieved by ground-based surveys but depending on the still highly uncertain type-classification by imaging data. More reliable classification will be achieved by the SNAP mission. The supernova counts at a magnitude level of I_{AB} or K_{AB} ~ 30 will allow us to break degeneracies between alpha and tau_{Ia} and independently constrain all the three parameters, even without knowing supernova types. This can be achieved by the SNAP and JWST missions, having different strength of larger statistics and reach to higher redshifts, respectively. The dependence of observable quantities on survey time intervals is also quantitatively calculated and discussed.

description: The interfacial Dzyaloshinskii-Moriya interaction (DMI) can be exploited in magnetic thin films to realize lateral chirally coupled systems, providing a way to couple different sections of a magnetic racetrack and realize interconnected networks of magnetic logic gates. Here, we systematically investigate the interplay between spin-orbit torques, chiral coupling and the device design in domain wall racetracks. We show that the current-induced domain nucleation process can be tuned between single-domain nucleation and repeated nucleation of alternate domains by changing the orientation of an in-plane patterned magnetic region within an out-of-plane magnetic racetrack. Furthermore, by combining experiments and micromagnetic simulations, we show that the combination of damping-like and field-like spin-orbit torques with DMI results in selective domain wall injection in one of two arms of a Y-shaped devices depending on the current density. Such an element constitutes the basis of domain wall based demultiplexer, which is essential for distributing a single input to any one of the multiple outputs in logic circuits. Our results provide input for the design of reliable and multifunctional domain-wall circuits based on chirally coupled interfaces.

description: Numerical simulations based on electronic structure calculations are finding ever growing applications in many areas of physics. A major limiting factor is however the cubic scaling of the algorithms used. Building on previous work [F. R. Krajewski and M. Parrinello, Phys.Rev. B71, 233105 (2005)] we introduce a novel statistical method for evaluating the inter-atomic forces which scales linearly with system size and is applicable also to metals. The method is based on exact decomposition of the fermionic determinant and on a mapping onto a field theoretical expression. We solve exactly the problem of sampling the Boltzmann distribution with noisy forces. This novel approach can be used in such diverse fields as quantum chromodynamics, quantum Monte Carlo or colloidal physics.

description: Purpose Zebrafish, a small fish model, exhibits a multipotent ability for retinal regeneration after damage throughout its lifetime. Compared with zebrafish, birds and mammals exhibit such a regenerative capacity only during the embryonic period, and this capacity decreases with age. In medaka, another small fish model that has also been used extensively in biological research, the retina’s inner nuclear layer (INL) failed to regenerate after injury in the hatchling at eight days postfertilization (dpf). We characterized the regenerative process of the embryonic retina when the retinal injury occurred during the early embryonic period in medaka. Methods We employed a 10 Gy dose of gamma-ray irradiation to initiate retinal injury in medaka embryos at 3 dpf and performed histopathological analyses up to 21 dpf. Results One day after irradiation, numerous apoptotic neurons were observed in the INL; however, these neurons were rarely observed in the ciliary marginal zone and the photoreceptor layer. Numerous pyknotic cells were clustered in the irradiated retina until two days after irradiation. These disappeared four days after irradiation, but the abnormal bridging structures between the INL and ganglion cell layer (GCL) were present until 11 days after irradiation, and the neural layers were completely regenerated 18 days after irradiation. After gamma-ray irradiation, the spindle-like Müller glial cells in the INL became rounder but did not lose their ability to express SOX2. Conclusion Irradiated retina at 3 dpf of medaka embryos could be completely regenerated at 18 days after irradiation (21 dpf), although the abnormal layer structures bridging the INL and GCL were transiently formed in the retinas of all the irradiated embryos. Four days after irradiation, embryonic medaka Müller glia were reduced in number but maintained SOX2 expression as in nonirradiated embryos. This finding contrasts with previous reports that 8 dpf medaka larvae could not fully regenerate damaged retinas because of loss of SOX2 expression.

description: Recently, the anomalous decay rate of quasinormal modes has been studied for some geometries under scalar field perturbations, which occurs when the longest-lived modes are the ones with higher angular number, as well as, the existence of a critical scalar field mass, i.e the value of scalar field mass such that the decay rate does not depend appreciably on the angular number, and beyond which the behaviour of the decay rate is inverted. Here, we consider the propagation of fermionic fields in the background of Schwarzschild de Sitter black holes, and we show that the anomalous decay rate behaviour and the fine structure, related to the coupling between the chirality and the mass of the field, can be observed in the fermionic spectrum.

description: Several works in the past decade have used the ratio between total (rest 8-1000$μ$m) infrared and radio (rest 1.4~GHz) luminosity in star-forming galaxies (q$_{IR}$), often referred to as the "infrared-radio correlation" (IRRC), to calibrate radio emission as a star formation rate (SFR) indicator. Previous studies constrained the evolution of q$_{IR}$ with redshift, finding a mild but significant decline, that is yet to be understood. For the first time, we calibrate q$_{IR}$ as a function of \textit{both} stellar mass (M$_{\star}$) and redshift, starting from an M$_{\star}$-selected sample of $>$400,000 star-forming galaxies in the COSMOS field, identified via (NUV-r)/(r-J) colours, at redshifts 0.1$

description: A novel proton imaging technique was applied which allows a continuous temporal record of electric fields within a time window of several nanoseconds. This "proton streak deflectometry" was used to investigate transient electric fields of intense (~ 10^17 W/cm^2) laser irradiated foils. We found out that these fields with an absolute peak of up to 10^8 V/m extend over millimeter lateral extension and decay at nanosecond duration. Hence, they last much longer than the (~ ps) laser excitation, and extend much beyond the laser irradiation focus.
The linguistic u-turn in the philosophy of thought
Creators: name: Fleming, Michael Neil
Publisher: name: University of British Columbia
Year: 2009

description: A central task of contemporary analytic philosophy is to develop an understanding of how our minds are connected to the external (or mind-independent) world. Arising from this task is the need to explain how thoughts represent things in the world. Giving such an explanation is the central endeavor of this dissertation—the aim being to contribute to our understanding of what it is for a subject to be thinking of a particular object. The structure of the dissertation is set, in part, by responding to the commonly held view that a satisfactory explanation of what it is to think of a particular object can be drawn out of, or extended from, an explanation of what it is to be referring to that particular object. Typically, in investigating these matters, it is accepted that there is an explanatory priority of language over thought. This is the Priority Thesis. Some take the Priority Thesis to reflect an appropriate methodological strategy. In this form, it implies the methodological point that the best way to describe thoughts is by describing them as they are expressed in language. Most, however, seem to take the Priority Thesis to be symptomatic of a substantive, metaphysical truth. This, to put it one way, is that the content of a thought is paralleled by the content of the associated linguistic expression. I call this the Assumption of Parallelism. This characterizes what we call Linguistic Turn philosophy (i.e., analytic philosophy). The body of the dissertation arises out of questioning the extent of the application ofthe Priority Thesis in developing theories of reference and thought. I call the move of the partial overturning ofthe Priority Thesis the Linguistic U-Turn. The overall conclusion is that we cannot explain what it is to think of a particular object by extending explanations of what it is to be referring to that particular object. In particular, I reject what I call the Causal Theory of Thought—the view that the representational properties of a thought are explained by the referential properties of the appropriate singular term. My aim, then, is to show that a popular conviction concerning the representational properties of thoughts about things in the world is not warranted.

description: Ultraluminous infrared galaxies (ULIRGs) represent a critical stage in the merger-driven evolution of galaxies when AGN activity is common and AGN feedback is expected. We present high sensitivity and large field of view intergral field spectroscopy of the ULIRG Mrk 273 using new data from the Keck Cosmic Web Imager (KWCI). The KCWI data captures the complex nuclear region and the two extended nebulae in the northeast (NE) and southwest (SW) to $\sim 20$ kpc scales. Kinematics in the nuclear region show a fast, extended, bipolar outflow in the direction of the previously reported nuclear superbubbles spanning $\sim 5$ kpc, two to three times greater than the previously reported size. The larger scale extended nebulae on $\sim 20$ kpc show fairly uniform kinematics with FWHM $\sim 300 ~\kmps$ in the SW nebula and FWHM $\sim 120 ~\kmps$ in the NE nebula. We detect for the first time high ionization [NeV]3426, [OIII]4363 and HeII4684 emission lines in the extended NE nebula. Emission line ratios in the nuclear region correlate with the kinematic structures, with the bipolar outflow and the less collimated "outflow regions" showing distinct line ratio trends. Line ratio diagnostics of high ionization emission lines reveal non-trivial contribution from shock plus precursor ionization in the NE nebula and the nuclear region, mixed with AGN photoionization. These data are highly constraining for models of cool ionized gas existing ~20 kpc from a galactic nucleus.

description: Observations in polarized emission reveal the existence of large-scale coherent magnetic fields in a wide range of spiral galaxies. Radio-polarization data show that these fields are strongly inclined towards the radial direction, with pitch angles up to $35\degr$ and thus cannot be explained by differential rotation alone. Global dynamo models describe the generation of the radial magnetic field from the underlying turbulence via the so called $α$-effect. However, these global models still rely on crude assumptions about the small-scale turbulence. To overcome these restrictions we perform fully dynamical MHD simulations of interstellar turbulence driven by supernova explosions. From our simulations we extract profiles of the contributing diagonal elements of the dynamo $α$-tensor as functions of galactic height. We also measure the coefficients describing vertical pumping and find that the ratio $\hatγ$ between these two effects has been overestimated in earlier analytical work, where dynamo action seemed impossible. In contradiction to these models based on isolated remnants we always find the pumping to be directed inward. In addition we observe that $\hatγ$ depends on whether clustering in terms of super-bubbles is taken into account. Finally, we apply a test field method to derive a quantitative measure of the turbulent magnetic diffusivity which we determine to be ~ 2 kpc kms.

description: We provide gauge/gravity dual descriptions of the strong coupling sector of composite Higgs models using insights from non-conformal examples of the AdS/CFT correspondence. We calculate particle masses and decay constants for proposed Sp(4) and SU(4) gauge theories, where there is the best lattice data for comparison. Our results compare favorably to lattice studies and go beyond those due to a greater flexibility in choosing the fermion content. That content changes the running dynamics and its choice can lead to sizable changes in the bound state masses. We describe top partners by a dual fermionic field in the bulk. Including suitable higher dimension operators can ensure a top mass consistent with the standard model.

description: Materials capable of highly efficient, direct thermal-to-electric energy conversion would have substantial economic potential. Theory predicts that thermoelectric efficiencies approaching the Carnot limit can be achieved at low temperatures in one-dimensional conductors that contain an energy filter such as a double-barrier resonant tunneling structure. The recent advances in growth techniques suggest that such devices can now be realized in heterostructured, semiconductor nanowires. Here we propose specific structural parameters for InAs/InP nanowires that may allow the experimental observation of near-Carnot efficient thermoelectric energy conversion in a single nanowire at low temperature.
Classification theorem and properties of singular solutions to the Tolman-Oppenheimer-Volkoff equation

description: The Tolman-Oppenheimer-Volkoff (TOV) equation admits singular solutions in addition to regular ones. Here, we prove the following theorem. For any equation of state that (i) is obtained from an entropy function, (ii) has positive pressure and (iii) satisfies the dominant energy condition, the TOV equation can be integrated from a boundary inwards to the center. Hence, thermodynamic consistency of the EoS precludes pathological solutions, in which the integration terminates at finite radius (because of horizons, or divergences / zeroes of energy density). At the center, the mass function either vanishes (regular solutions) or it is negative (singular solutions). For singular solutions, the metric at the center is locally isomorphic to negative-mass Schwarzschild spacetime. This means that matter is stabilized because the singularity is strongly repulsive. We show that singular solutions are causally well behaved: they are bounded-acceleration complete, and they are conformal to a globally hyperbolic spacetime with boundary. Finally, we show how to modify unphysical equations of state in order to obtain non-pathological solutions, and we undertake a preliminary investigation of dynamical stability for singular solutions.

description: The plane-of-satellites problem is one of the most severe small-scale challenges for the standard $Λ$CDM cosmological model: several dwarf galaxies around the Milky Way and Andromeda co-orbit in thin, planar structures. A similar case has been identified around the nearby elliptical galaxy Centaurus A (Cen A). In this Letter, we study the satellite system of Cen A adding twelve new galaxies with line-of-sight velocities from VLT/MUSE observations. We find 21 out of 28 dwarf galaxies with measured velocities share a coherent motion. Similarly flattened and coherently moving structures are found only in 0.2% of Cen A analogs in the Illustris-TNG100 cosmological simulation, independently of whether we use its dark-matter-only or hydrodynamical run. These analogs are not co-orbiting, and arise only by chance projection, thus they are short-lived structures in such simulations. Our findings indicate that the observed co-rotating planes of satellites are a persistent challenge for $Λ$CDM, which is largely independent from baryon physics.

description: We examine the evolution of peculiar velocities of cold dark matter (CDM) in localized arrays of inhomogeneous cosmic structures in a $Λ$CDM background that can be identified as a frame comoving with the Cosmic Microwave (CMB). These arrays are constructed by smoothly matching to this cosmological background regions of Szekeres-II models whose source is an imperfect fluid reinterpreted as non-comoving dust, keeping only first order terms in $v/c$. Considering a single Szekeres-II region matched along two comoving interfaces to a $Λ$CDM background, the magnitudes of peculiar velocities within this region are compatible with values reported in the literature, while the present day Hubble expansion scalar differs from that of the $Λ$CDM background value by a 10\% factor, a result that might provide useful information to the ongoing debate on the $H_0$ tension. While the models cannot describe the virialization process, we show through a representative example that structures of galactic cluster mass reach the onset of this process at redshifts around $z\sim 3$.

Population III and the Near-Infrared Background Excess
Creators: name: Madau, Piero

Subjects: subject: Astrophysics (astro-ph)

description: We make a critical assessment of models that attribute the recently detected near-infrared background ``excess'' (NIRBE) to the redshifted light from Population III objects. To supply the required 25 keV/baryon at redshift 9, Pop III massive stars must form with an efficiency exceeding 30% in all ``minihalos'' with virial temperatures above a few hundred kelvins: to avoid excessive metal pollution, most of the baryons once in Pop III stars must end up in intermediate-mass black holes (IMBHs). Gas accretion onto such IMBHs must either be inhibited or lead to early miniquasars with steep UV/X-ray spectra, in order not to overproduce the present-day unresolved soft X-ray background. In the latter case (NIRBE dominated by "X-ray quiet miniquasars"), the total mass density of IMBHs at redshift 9 must be >50 times higher than the mass density of supermassive black holes observed today in the nuclei of galaxies. A stellar-dominated NIRBE is less economical energetically: more than 5% of all baryons in the universe must be processed into Population III stars. We survey various aspects of the Population III hypothesis for the NIRBE, and show that the ionizing photon budget required to account for the NIRBE is much larger than that required to explain the high electron scattering optical depth measured by the WMAP satellite.

description: Photonic crystal (PC) coupled cavity waveguides (CCWs) with \textit{completely separated eigenfrequencies} (or supermodes) are investigated. Using a coupled mode theory, the properties of the supermodes, such as the electric field profiles, the eigenfrequencies (including the central frequencies and corresponding linewidths), and the quality factors (Qs) are expressed in very simple formulas, and these results agree well with those of ``exact'' numerical method. We also discuss the great differences between the supermodes and \textit{continuous modes}, which are described by tight binding (TB) theory. Then, the properties of supermodes are used to investigate their potential applications in multichannel (covering the whole C-band) bistable switchings, and bistable loops are obtained numerically. We also predict and verify that all the thresholds are uniform inherently.

description: Dramatic increases in levels and volatility of gasoline prices observed in recent years may create market incentives for adoption of alternative fuels characterized by lower price volatility. This hypothesis is investigated by applying the real-options pricing approach to develop optimal thresholds for switching from conventional gasoline to alternative fuels such as ethanol blends. The main result of the paper is that given the historical price patterns of conventional gasoline and ethanol, switching to ethanol blends is an economically sound decision provided this does not decrease efficiency of the vehicle. Analysis of data subsamples during the periods of higher volatility of gasoline prices (Gulf War and War on Terrorism) provides even stronger support for this result.

subject: Standard Reinsurance Agreement

description: This paper examines how insurance companies participating in delivery of crop insurance would change patterns of portfolio allocation across reinsurance funds in reaction to the 2005 Standard Reinsurance Agreement. The returns of insurance companies under the SRA are calculated using a simulation model. An heuristic allocation rule is introduced in order to imitate portfolio allocation strategies of participating companies. The main conclusion of the analysis is that the bulk of changes in portfolio allocations are likely to be caused by the introduction of "retained net book quota share" reinsurance rather than adjustments in the cession limits and retention requirements for the Assigned Risk Fund.

description: The identification of improved methods for characterizing crop yield densities has experienced a recent surge in activity due in part to the central role played by crop insurance in the Agricultural Risk Protection Act of 2000 (estimates of yield densities are required for the determination of insurance premium rates). Nonparametric kernel methods have been successfully used to model yield densities; however, traditional kernel methods do not handle the presence of categorical data in a satisfactory manner and have therefore tended to be applied on a county-by-county basis. By utilizing recently developed kernel methods that admit mixed data types, we are able to model the yield density jointly across counties, leading to substantial finite sample efficiency gains. Findings show that when we allow insurance companies to strategically reinsure with the government based on this novel approach they accrue significant rents.

description: Galaxy clusters are the largest virialised objects in the Universe, and as such, have a high dark matter (DM) concentration. This abundance of dark matter makes them promising targets for indirect DM searches. Here we report the details of a search, utilising almost 12~years of Fermi/LAT data, for gamma ray signatures from the pair annihilation of WIMP dark matter in the GeV energy band. From this, we present the constraints on the annihilation cross section for the bb-bar, W+W- and gamma-gamma channels, derived from the non-detection of a characteristic signal from five nearby high galactic latitude galaxy clusters (Centaurus, Coma, Virgo, Perseus and Fornax). We discuss the potential of a boost to the signal due the presence of substructures in the DM halos of selected objects, as well as the impact of uncertainties in DM profiles on the presented results. We assert that the obtained limits are, within a small factor, comparable to the best available limits of those based on Fermi/LAT observations of dwarf spheroidal galaxies.

description: A space-time econometric model was developed for pine sawtimber timber prices of 21 geographically contiguous regions in the southern United States. The correlations between prices in neighboring regions helped predict future prices. The impulse response analysis showed that although southern pine sawtimber markets were not globally integrated, local supply and demand shocks did transmit partially to immediate neighboring regions, and could also have weaker effects in more distant regions.

description: The spatial coverage produced by a single discrete-time random walk, with asymmetric jump probability $p\neq 1/2$ and non-uniform steps, moving on an infinite one-dimensional lattice is investigated. Analytical calculations are complemented with Monte Carlo simulations. We show that, for appropriate step sizes, the model displays a critical phenomenon, at $p=p_c$. Its scaling properties as well as the main features of the fragmented coverage occurring in the vicinity of the critical point are shown. In particular, in the limit $p\to p_c$, the distribution of fragment lengths is scale-free, with nontrivial exponents. Moreover, the spatial distribution of cracks (unvisited sites) defines a fractal set over the spanned interval. Thus, from the perspective of the covered territory, a very rich critical phenomenology is revealed in a simple one-dimensional standard model.

description: A national telephone survey was conducted in the United States in April 2002 to study the consumer acceptance of genetically modified (GM) foods. Attitudes toward GM foods were examined through the use of a multiple correspondence analysis (MCA), analyzing the interrelationships among many categorical variables. This method was combined with a cluster analysis to construct a typology of consumers' attitudes. Four distinct classes of attitudes were finally extracted, denoted as: Proponents, Non-Opponents, Moderate Opponents, and Extreme Opponents. It was estimated that only 35% of the surveyed population was opposed to GM foods.
How to do more for less? An urgent call for the expanded use of mathematical operations research to help reach the UNAIDS 90-90-90 targets

description: The United Nations Joint Programme on HIV/AIDS (UNAIDS) recently announced the 90-90-90 targets to guide global expansion of access to antiretroviral therapy. Reaching these targets will  require a massive expansion of HIV health services, to more than double current antiretroviral therapy (ART) coverage within five years. As continued funding shortages to resource the HIV/AIDS response are likely, the optimal delivery of HIV treatment and care to maximize the impact of investments will become more crucial than ever. Operations research (OR) is a sub-field of mathematics, which uses analytical methods to design optimal systems, processes and interventions. Widely applied in optimizing business, industrial and health care system operations, mathematical OR methods are severely underutilised within the HIV response, We reviewed the mathematical OR literature to identify studies relevant to the 90-90-90 strategy. Areas for OR application include (i) budget and resource allocation from facility to international levels; (ii) production, supply and delivery of antiretroviral drugs; (iii) development of HIV testing strategies; (iv) improving the HIV care and treatment continuum; and (v) clinical patient monitoring and surveillance. Reviewing current Global Fund, WHO, and UNAIDS guidelines we found that existing OR frameworks for HIV focus on: identifying service-delivery bottlenecks; implementing operational interventions; post-implementation monitoring and evaluation of interventions. Instructions on methodology are provided only for steps and. Step is best informed by mathematical OR methods including modelling, simulation, optimization, resource allocation analysis, capacity planning, facility location, routing and related methods of intervention design. In part due to a misleading commonality in terminology, mathematical OR methods are underutilized in designing interventions for best use of scarce resources, maximum epidemiological impact and accelerated progress toward 90-90-90 goals. Mathematical OR methods should be embraced to inform 90-90-90 and could be easily adapted into existing frameworks guiding HIV-related OR. A large body of research published outside the mainstream HIV literature on or applicable to HIV demonstrates how optimal use of existing resources could dramatically improve service delivery and health outcomes. Many mathematical OR experts already consult on individual HIV projects and yet are not engaged with the HIV community. Actively engaging these experts could provide critical knowledge to inform policy relevant to the 90-90-90 goals.

description: Using single-crystal organic field-effect transistors with the conduction channel exposed to environmental agents we have observed generation of electronic defects at the organic surface in the high-vacuum environment. Rapid decrease of the source-drain current of an operating device is observed upon exposure of the channel to the species generated by high-vacuum gauges. We attribute this effect to interaction of the organic surface with electrically neutral free radicals produced in the process of hydrocarbon cracking on hot filaments with a relatively low activation energy Ea ~ 2.5 eV (240 kJ/mol). The reported results might be important for optimizing the high-vacuum processes of fabrication and characterization of a wide range of organic and molecular electronic devices.
