description: The High-z Supernova Search Team has discovered and observed 8 new supernovae in the redshift interval z=0.3-1.2. These independent observations, confirm the result of Riess et al. (1998a) and Perlmutter et al. (1999) that supernova luminosity distances imply an accelerating universe. More importantly, they extend the redshift range of consistently observed SN Ia to z~1, where the signature of cosmological effects has the opposite sign of some plausible systematic effects. Consequently, these measurements not only provide another quantitative confirmation of the importance of dark energy, but also constitute a powerful qualitative test for the cosmological origin of cosmic acceleration. We find a rate for SN Ia of 1.4+/-0.5E-04 h^3/Mpc^3/yr at a mean redshift of 0.5. We present distances and host extinctions for 230 SN Ia. These place the following constraints on cosmological quantities: if the equation of state parameter of the dark energy is w=-1, then H0 t0 = 0.96+/-0.04, and O_l - 1.4 O_m = 0.35+/-0.14. Including the constraint of a flat Universe, we find O_m = 0.28+/-0.05, independent of any large-scale structure measurements. Adopting a prior based on the 2dF redshift survey constraint on O_m and assuming a flat universe, we find that the equation of state parameter of the dark energy lies in the range -1.48-1, we obtain w

Infinite compressibility states in the Hierarchical Reference Theory of fluids. I. Analytical considerations
Creators: name: Reiner, Albert
Publisher: name: arXiv
Year: 2003
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: In its customary formulation for one-component fluids, the Hierarchical Reference Theory yields a quasilinear partial differential equation for an auxiliary quantity f that can be solved even arbitrarily close to the critical point, reproduces non-trivial scaling laws at the critical singularity, and directly locates the binodal without the need for a Maxwell construction. In the present contribution we present a systematic exploration of the possible types of behavior of the PDE for thermodynamic states of diverging isothermal compressibility kappa[T] as the renormalization group theoretical momentum cutoff approaches zero. By purely analytical means we identify three classes of asymptotic solutions compatible with infinite kappa[T], characterized by uniform or slowly varying bounds on the curvature of f, by monotonicity of the build-up of diverging kappa[T], and by stiffness of the PDE in part of its domain, respectively. These scenarios are analzyed and discussed with respect to their numerical properties. A seeming contradiction between two of these alternatives and an asymptotic solution derived earlier [Parola et al., Phys. Rev. E 48, 3321 (1993)] is easily resolved.

description: The existence of a fundamental ultraviolet scale, such as the Planck scale, may lead to modifications of the dispersion relations for particles at high energies, in some scenarios of quantum gravity. We apply effective field theory to this problem and identify dimension 5 operators that do not mix with dimensions 3 and 4 and lead to cubic modifications of dispersion relations for scalars, fermions, and vector particles. Further we show that, for electrons, photons and light quarks, clock comparison experiments bound these operators at 10^{-5}/Mpl.

Connections between resonance and nonlinearity in swimming performance of a flexible heaving plate

Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We investigate the role of resonance in finite-amplitude swimming of a flexible flat plate in a viscous fluid. The role of resonance in performance remains unclear for two reasons: i) a lack of definition of resonance for the fully-coupled fluid-structure interaction system in a viscous flow, and ii) the presence of nonlinear effects, which makes it difficult to disentangle resonant and non-resonant mechanisms in finite-amplitude swimming. We address point i) and provide an unambiguous definition for system resonance by computing global linear stability modes of the fully-coupled fluid-structure interaction system that account for the viscous fluid, the plate, and the coupling between them. We then resolve point ii) by considering high-fidelity nonlinear simulations of systematically increased amplitude. By comparing the results for different amplitudes with one another and with the linear stability modes, we separate linear and/or resonant effects from nonlinear and/or non-resonant effects. Resonant behavior is observed over a wide range of plate stiffnesses, with peaks in trailing-edge motion and thrust occurring near the resonant frequency defined by the global linear analysis. The peaks broaden and weaken with increasing heave amplitude, consistent with an increased damping effect from the fluid. At the same time, non-resonant mechanisms are present at large heave amplitudes. The input power exhibits qualitatively different dynamics at large heave amplitudes compared to smaller heave amplitudes, where resonance dominates. Moreover, leading-edge separation is present for stiff plates at large heave amplitudes, which can drastically alter the performance characteristics from what one would expect through linear predictions.
Self-interaction of ultrashort pulses in an epsilon-near-zero nonlinear material at the telecom wavelength

description: Dynamics of femtosecond pulses with the telecom carrier wavelength is investigated numerically in a subwavelength layer of an indium tin oxide (ITO) epsilon-near-zero (ENZ) material with high dispersion and high nonlinearity. Due to the subwavelength thickness of the ITO ENZ material, and the fact that the pulse's propagation time is shorter than its temporal width, multiple reflections give rise to self-interaction in both spectral and temporal domains, especially at wavelengths longer than the ENZ point, at which the reflections are significantly stronger. A larger absolute value of the pulse's chirp strongly affects the self-interaction by redistributing energy between wavelengths, while the sign of the chirp affects the interaction in the temporal domain. It is also found that, when two identical pulses are launched simultaneously from both ends, a subwavelength counterpart of a standing-wave state can be established. It shows robust energy localization in the middle of the sample, in terms of both the spectral and temporal intensity distributions.

description: Abstract:
Understanding chemical reactivity of surface-attached functional groups with gaseous reactive species is critical for many applications including atmospheric chemistry, paints/coatings and sensors. As contributors to the RADICAL consortium working on atmospheric radical sensors1, we have studied reactions of ozone and non-thermal He/H2O/O2 plasma (as a source of hydroxyl radicals) with functionalized self-assembled monolayers on non-porous silica nanoparticles and planar silica substrates. In order to characterize the reaction products on silica nanoparticles, we have developed methodology for removing the monolayer from the surface to yield soluble products that can be analysed by conventional analytical techniques.
We are particularly interested in the effect of monolayer environment (e.g., the presence of adjacent molecules, monolayer thickness, position of the functional group in the monolayer) on the kinetics and chemical reactivity of the monolayers. Initial results suggest that the reactivity follows a similar trend to the bulk condensed phases with higher ozone reactivity for shorter monolayers.

description: Situated learning experiences such as research apprenticeships can help connect girls to the sciences, ultimately helping to achieve gender equity in the science workforce. The material resources available in research apprenticeships—such as research equipment, field gear, etc.—may be particularly consequential for building identification with science, as they are abundant and frequently hold disciplinary authenticity. However, most sociocultural studies of research apprenticeships have focused on cognitive-ideational or social aspects rather than on the material aspects of the learning setting. This paper investigates the association between different types of science-related material resources in the context of a geoscience and biology-focused research apprenticeship program for girls. The study employed a qualitative approach, drawing on theoretical constructs of communities of practice, identity resources, and identity work to inform program design and analysis. Our findings highlight specific ways that instruments, specialized clothing, specimens, artifacts, and physical settings of science intersect with science-related affect, science learning, and a sense of “feeling like a scientist.” The results imply that practitioners both in and out of the classroom should privilege agentic use of tools when working with all learners, but especially girls. Further, the types of material resources selected in learning settings are critically important, as different types of material resources afford different types of identity work. In particular, using materials that hold disciplinary authenticity, when coupled with learning about how scientists use those same instruments, helps girls “feel like scientists,” an important part of becoming a science apprentice.

description: Using the techniques of Neural Networks (NN), we study the three-dimensional (3D) 5-state ferromagnetic Potts model on the cubic lattice as well as the two-dimensional (2D) 3-state antiferromagnetic Potts model on the square lattice. Unlike the conventional approach, here we follow the idea employed in Ann.~Phy.~391 (2018) 312-331. Specifically, instead of numerically generating numerous objects for the training, the whole or part of the theoretical ground state configurations of the studied models are considered as the training sets. Remarkably, our investigation of these two models provides convincing evidence for the effectiveness of the method of preparing training sets used in this study. In particular, the results of the 3D model obtained here imply that the NN approach is as efficient as the traditional method since the signal of a first order phase transition, namely tunneling between two channels, determined by the NN method is as strong as that calculated with the Monte Carlo technique. Furthermore, the outcomes associated with the considered 2D system indicate even little partial information of the ground states can lead to conclusive results regarding the studied phase transition. The achievements reached in our investigation demonstrate that the performance of NN, using certain amount of the theoretical ground state configurations as the training sets, is impressive.

Nucleosynthesis in Early Stars

description: We present preliminary results of stellar structure and nucleosynthesis calculations for some early stars. The study (still in progress) seeks to explore the expected chemical signatures of second generation low- and intermediate-mass stars that may have formed out of a combination of Big Bang and Pop III (Z=0) supernovae material. Although the study is incomplete at this stage, we find some important features in our models. The initial chemical composition of these early stars is found to be significantly different to that given by just scaling the solar composition. The most notable difference is the lack of nitrogen. This should not affect the structural evolution significantly as nitrogen will be quickly produced through the CNO cycle due to the presence of carbon (and oxygen). It should however effect the nucleosynthetic yields. We also find that our very low metallicity five solar-mass model, with [Fe/H]=-4.01, does not reach the RGB - it goes directly to the helium burning phase. It does not experience the first dredge-up either. This is not a new finding but it will have an effect on the surface chemical evolution of the stars and should alter the nucleosynthetic yields that we are currently calculating. Our higher metallicity stars, with a globular cluster composition at [Fe/H]= -1.40, do experience all the standard phases of evolution but also have significantly higher surface temperatures and luminosities compared to solar metallicity stars. Their internal temperatures are also higher which should again effect the final nucleosynthetic yields.

description: We consider toy cosmological models in which a classical, homogeneous, spinor field provides a dominant or sub-dominant contribution to the energy-momentum tensor of a flat Friedmann-Robertson-Walker universe. We find that, if such a field were to exist, appropriate choices of the spinor self-interaction would generate a rich variety of behaviors, quite different from their widely studied scalar field counterparts. We first discuss solutions that incorporate a stage of cosmic inflation and estimate the primordial spectrum of density perturbations seeded during such a stage. Inflation driven by a spinor field turns out to be unappealing as it leads to a blue spectrum of perturbations and requires considerable fine-tuning of parameters. We next find that, for simple, quartic spinor self-interactions, non-singular cyclic cosmologies exist with reasonable parameter choices. These solutions might eventually be incorporated into a successful past- and future-eternal cosmological model free of singularities. In an Appendix, we discuss the classical treatment of spinors and argue that certain quantum systems might be approximated in terms of such fields.

Experimental Investigation of a Novel Boundary Layer Ingestion Engine Intake with S-Shaped Geometry

Subjects: subject: 90199 Aerospace Engineering not elsewhere classified

description: ABSTRACTThis paper presents the experimental study of athree-dimensional flow, accompanied by several fluid-induced phenomena. These phenomena appear at boundary layer ingesting aero-engine intakes of S-shape geometry. The main variable of the experiment is the geometry of the intake. To account for the variation two different geometries in the form of S-shape were examined where the ratios of length (L) - height (H) had become 5.625 and 11.25 respectively. Initially, the oil and pigment visualization technique is performed to visualize flow phenomena in the suction field of the propulsion unit. Pressure measurements of the flow were conducted at three levels longitudinal to the inlet duct for the depiction of pressure distribution. Moreover, measurements were made at the end of the S-duct after the placement of an improvement geometry at the aerodynamic interface plane (AIP) of the fans. The specific geometry was used to reduce the distortions of flow within the S-duct. The shape of geometry reminds a Beak, to smoothly guide the flow into the fans. The study was conducted in an experimental wind tunnel. The device consists of two fan arrays, the first simulating the flight velocity V∞ and the second the propulsion velocity Vj. The geometry of the S-duct changes via a special mechanism. The monitoring and recording of fan rotational speeds was achieved using infrared sensors. In addition, the pressure measurements were conducted with a cobra five-hole probe. The visualization method was employed after the placement of the Beak geometries. The process showed that the flow lines do not completely embrace the Beak geometries and there are signs of saddle points. As the L/H ratio decreases, i.e., the geometry becomes more aggressive, the saddle points produced by the Beak geometries grow upstream, resulting in stronger losses. Finally, the measurements with the Beak geometries reveal an increase of 1.9% in total pressure for the 11.25 ratio case and 0.15% for the other case. Also, it has been shown that Beak geometries reduce the Yaw angle generated from the array of five fans by 28.1% and 10% respectively for the two cases.

Toroidal States of the $^{12}$C Nucleus

subject: FOS: Physical sciences

description: Among the states of $^{12}$C, there is an important subset of $K$=0 and $K$=$I$ planar intrinsic states in which the intrinsic motion of the nucleons are confined in the planar region defined by the three-alpha cluster or by their generated toroid. The intrinsic nuclear densities of these states are toroidal in nature. We study these $^{12}$C toroidal states from the generator-coordinate viewpoints in both the alpha cluster model and the toroidal shell model. Numerical solutions in the toroidal mean field approximation are examined to pave the way for future extensions and refinements.

description: The problem of data security in IEEE 802.15.4 systems on Pololu Wixel devices is solved, examples of hardware and software implementation of encryption and decryption of different devices on the same platform are given. The proposed approaches can be used in the development, implementation and operation of wireless enterprise, industrial, and personal systems. Possible areas of development for this work are related to research on improving encryption algorithms (increasing key length, using asymmetric ciphers, etc.), comparing their performance, and implementing a complete data exchange protocol. During the work there were problems in the implementation of encryption algorithms on low-power processors. During the work, a number of issues were resolved regarding type reduction, addressing, memory space, buffer overflow, and more. Issues resolved with reconciliation of receiver and transmitter operation. Examples of hardware and software implementation of encryption and decryption of different devices based on Pololu Wixel are given in the paper. The basic task of building a secure communication channel by encrypting data in the channel was solved and firmware and application software were obtained to fully validate the devices. In addition, this work has great application potential, since the implementation of encryption in existing systems will have a small impact on implementation and will not affect the project budget, but will dramatically improve the security of data transmission in these networks. The proposed approaches can be used in the development, implementation and operation of wireless enterprise, industrial, and personal systems. Continuing this work may be to test the performance of other protocols on this and similar hardware for systems that may be embedded in short-range wireless communication projects of short-range standards.

description: Purpose: This study reports a secondary analysis of the nature of communicative functions and modalities used in initiations and responses of minimally verbal preschoolers with severe autism spectrum disorder (ASD) from a previously published study (Thiemann-Bourque, Feldmiller, Hoffman, & Johner, 2018). This analysis focused on the final cohort (n = 6) from a group design study (N = 45) that examined a peer mediation and speech-generating device (SGD) intervention compared to an SGD-only condition.Method: After teaching peers to use an iPad as an SGD within a modified stay-play-talk approach, school staff implemented SGD instruction in child–peer dyads during typical preschool activities. To investigate individual differences among children who demonstrated increased communication acts in the peer + SGD condition, changes in reciprocity, modalities used, and communicative functions were examined using a multiple-baseline design across children. Fidelity of implementation and social validity data were also collected.Results: Six children with ASD and their peers demonstrated more balanced reciprocity, with individual differences in how and why children communicated during exchanges. That is, all children with ASD increased in SGD use as their primary communication mode; 3 children used different modalities including more speech, and 3 children used primarily gestures and SGD. The most frequent function expressed was requests for objects. More modest increases were observed in comments and requests for actions, with negligible changes in gaining attention. Social validity reports by naïve judges reflected clear improvements in communication interactions. Conclusion: Findings are promising for a preschool SGD intervention that can expand children’s modalities and communicative functions to engage in balanced exchanges with peer partners.

description: We use a unique dataset that combines the responses from an original survey of households, information about the structural characteristics of their homes, utility-provided longitudinal electricity usage records, plus utility program participation information, to study the uptake of energy efficiency incentives and their effect on residential electricity consumption. Attention is restricted to homes where heating and cooling are provided exclusively by heat pumps, which are common in our study area—four counties in Maryland—and were covered by federal, state and utility incentives during our study period (2007-2012). We deploy a difference-in-difference study design. We find that replacing an existing heat pump with a new one does reduce electricity usage: the average treatment effect is an 8% reduction. However, the effect differs dramatically across households based upon whether they receive an incentive towards the purchase of a new heat pump. Among those that receive the purchase incentive, the effect is small or nil, and indeed, the larger the incentive, the smaller the reduction in electricity usage. Those that do not receive incentives reduce usage by about 16%. Our results appear to be driven by the numerous free riders in our sample and by persons who—inferred from their responses to survey questions—might be exploiting the subsidy to purchase a larger system and increase usage, with no emissions reductions benefits to society.
A Simple Formula for the Social Cost of Carbon

description: The social cost of carbon (SCC), commonly referred to as the carbon price, is the monetized damage from emitting one unit of CO2 to the atmosphere. The SCC is typically obtained from large‐scale computational Integrated Assessment Models (IAMs) that consolidate interdisciplinary climate research inputs to obtain a carbon price estimate relevant for policy‐making. However, the climate economy interactions of IAMs remain inaccessible to scientists in general. Here we develop a simple closed‐form formula that captures the key physical and economic determinants of the SCC in the IAMs. For a mainstream IAM, it explains over 99 percent of the within‐model variation originating from structural uncertainties; in an inter‐model comparison, the structural variation captured by the formula matches closely a SCC distribution of previous SCC estimates. The precise replication of the SCC estimates is strikingly free of details such as those on future policy and technology options, or even carbon concentration levels; the size of the current economy and the emissions‐temperature‐damage response are the dominant SCC determinants in the IAMs. The structural interpretation given allows decision‐makers to disentangle the subjective and structural determinants of the carbon price. Structural uncertainties alone lead to a strongly right‐skewed density with median 15 €/tCO2, mean 31 €/tCO2, and more than 5 percent probability for higher than 100 €/tCO2 for year 2015.
A Micromechanical Constitutive Model for the Dynamic Response of Brittle Materials "Dynamic Response of Marble"

Publisher: name: California Institute of Technology
Year: 2000
Subjects: Aeronautics

description: A micromechanically based constitutive model for the dynamic inelastic behavior of brittle materials, specifically "Dionysus-Pentelicon marble" with distributed microcracking is presented. Dionysus-Pentelicon marble was used in the construction of the Parthenon, in Athens, Greece. The constitutive model is a key component in the ability to simulate this historic explosion and the preceding bombardment form cannon fire that occurred at the Parthenon in 1678. Experiments were performed by Rosakis (1999) that characterized the static and dynamic response of this unique material. A micromechanical constitutive model that was previously successfully used to model the dynamic response of granular brittle materials is presented. The constitutive model was fitted to the experimental data for marble and reproduced the experimentally observed basic uniaxial dynamic behavior quite well. This micromechanical constitutive model was then implemented into the three dimensional nonlinear lagrangain finite element code Dyna3d(1998). Implementing this methodology into the three dimensional nonlinear dynamic finite element code allowed the model to be exercised on several preliminary impact experiments. During future simulations, the model is to be used in conjunction with other numerical techniques to simulate projectile impact and blast loading on the Dionysus-Pentelicon marble and on the structure of the Parthenon.

description: For a pair of coupled rectangular random matrices we consider the squared singular values of their product, which form a determinantal point process. We show that the limiting mean distribution of these squared singular values is described by the second component of the solution to a vector equilibrium problem. This vector equilibrium problem is defined for three measures with an upper constraint on the first measure and an external field on the second measure. We carry out the steepest descent analysis for a 4 $\times$ 4 matrix-valued Riemann-Hilbert problem, which characterizes the correlation kernel and is related to mixed type multiple orthogonal polynomials associated with the modified Bessel functions. A careful study of the vector equilibrium problem, combined with this asymptotic analysis, ultimately leads to the aforementioned convergence result for the limiting mean distribution, an explicit form of the associated spectral curve, as well as local Sine, Meijer-G and Airy universality results for the squared singular values considered.

description: I present a Hamiltonian model and a computational method suitable to evaluate structural and thermodynamic properties of helical molecules embedded in crowded environments which may confine the space available to the base pair fluctuations. It is shown that, for the specific case of a short DNA fragment in a nanochannel, the molecule is markedly over-twisted and stretched by narrowing the width of the channel.
