description: The Immersed Boundary method has evolved into one of the most useful computational methods in studying fluid structure interaction. On the other hand, the Immersed Boundary method is also known to suffer from a severe timestep stability restriction when using an explicit time discretization. In this paper, we propose several efficient semi-implicit schemes to remove this stiffness from the Immersed Boundary method for the two-dimensional Stokes flow. First, we obtain a novel unconditionally stable semi-implicit discretization for the immersed boundary problem. Using this unconditionally stable discretization as a building block, we derive several efficient semi-implicit schemes for the immersed boundary problem by applying the Small Scale Decomposition to this unconditionally stable discretization. Our stability analysis and extensive numerical experiments show that our semi-implicit schemes offer much better stability property than the explicit scheme. Unlike other implicit or semi-implicit schemes proposed in the literature, our semi-implicit schemes can be solved explicitly in the spectral space. Thus the computational cost of our semi-implicit schemes is comparable to that of an explicit scheme, but with a much better stability property.

description: Although cosmic microwave background (CMB) is the most powerful cosmological probe of neutrino masses, it is in trouble with local direct measurements of $H_0$, which is called the $H_0$ tension. Since neutrino masses are correlated with $H_0$ in CMB, one can expect the cosmological bound on neutrino masses would be much affected by the $H_0$ tension. We investigate what impact this tension brings to cosmological bound on neutrino masses by assuming a model with modified recombination which has been shown to resolve the tension. We argue that constraints on neutrino masses become significantly weaker in models where the $H_0$ tension can be resolved.

An Improved HR Diagram for the Orion Trapezium Cluster

description: In this paper, we present a study of the Trapezium cluster in Orion. We analyze flux-calibrated VLT/MUSE spectra of 361 stars to simultaneously measure the spectral types, reddening, and the optical veiling due to accretion. We find that the extinction law from Cardelli et al. (1989) with a total-to-selective extinction value of $R_{\rm V}=$5.5 is more suitable for this cluster. For 68% of the sample the new spectral types are consistent with literature spectral types within 2 subclasses, but as expected, we derive systematically later types than the literature by one to two subclasses for the sources with significant accretion levels. Here we present an improved Hertzsprung-Russell (H-R) diagram of the Trapezium cluster, in which the contamination by optical veiling on spectral types and stellar luminosities has been properly removed. A comparison of the locations of the stars in the H-R diagram with the non-magnetic and magnetic pre-main sequence evolutionary tracks indicates an age of 1--2~Myr. The magnetic pre-main sequence evolutionary tracks can better explain the luminosities of the low-mass stars. In the H-R diagram, the cluster exhibits a large luminosity spread ($σ$(Log~$L_{\star}/L_{\odot})\sim$0.3). By collecting a sample of 14 clusters/groups with different ages, we find that the luminosity spread tends to be constant ($σ$(Log~$L_{\star}/L_{\odot})\sim$0.2--0.25) after 2~Myr, which suggests that age spread is not the main cause of the spread. There are $\sim$0.1~dex larger luminosity spreads for the younger clusters, e.g., the Trapezium cluster, than the older clusters, which can be explained by the starspots, accretion history and circumstellar disk orientations.

description: Using small-angle neutron scattering we have studied the superconducting vortex lattice (VL) phase diagram in MgB2 as the applied magnetic field is rotated away from the c axis and towards the basal plane. The field rotation gradually suppresses the intermediate VL phase which exists between end states aligned with two high symmetry directions in the hexagonal basal plane for H || c. Above a critical angle, the intermediate state disappears, and the previously continuous transition becomes discontinuous. The evolution towards the discontinuous transition can be parameterized by a vanishing twelvefold anisotropy term in the VL free energy.

description: A number of experimental techniques are currently being deployed in an effort to make the first detection of ultra-high energy cosmic neutrinos. To accomplish this goal, techniques using radio and acoustic detectors are being developed, which are optimally designed for studying neutrinos with energies in the PeV-EeV range and above. Data from the AMANDA experiment, in contrast, has been used to place limits on the cosmic neutrino flux at less extreme energies (up to ~10 PeV). In this letter, we show that by adopting a different analysis strategy, optimized for much higher energy neutrinos, the same AMANDA data can be used to place a limit competitive with radio techniques at EeV energies. We also discuss the sensitivity of the IceCube experiment, in various stages of deployment, to ultra-high energy neutrinos.

description: Producing a bushel of wheat cost U.S. farmers an average of $2.07 in variable cash expenses in 1989. Individual farm costs ranged from less than $1.37 to more than $3.49 per bushel. Wheat acreage, yields, and regional differences among producers influenced wheat production costs. Differences in regional production practices and adverse weather conditions were major influences on production costs and yields. Dry weather and warm temperatures reduced already low subsoil moisture levels throughout the Plains in 1989, resulting in lower wheat yields. Low snowfall and low temperatures caused freeze damage in some parts of the Central and Southern Plains region (CO, KS, NE, OK, and TX), resulting in that region's accounting for 64 percent of all farms in the high-cost group.

description: This paper presents two approaches to mathematical modelling of a synthetic seismic pulse, and a comparison between them. First, a new analytical model is developed in two-dimensional Cartesian coordinates. Combined with an initial condition of sufficient symmetry, this provides a valuable check for the validity of the numerical method that follows. A particular initial condition is found which allows for a new closed-form solution. A numerical scheme is then presented which combines a spectral (Fourier) representation for displacement components and wave-speed parameters, a fourth order Runge-Kutta integration method, and an absorbing boundary layer. The resulting large system of differential equations is solved in parallel on suitable enhanced performance desktop hardware in a new software implementation. This provides an alternative approach to forward modelling of waves within isotropic media which is efficient, and tailored to rapid and flexible developments in modelling seismic structure, for example, shallow depth environmental applications. Visual comparisons of the analytic solution and the numerical scheme are presented.

Soldiers of the King: Vancouver’s interwar militia as a social institution
Creators: name: Yuill, Ian David Campbell
Publisher: name: University of British Columbia
Year: 2009

description: The interwar militia in Vancouver is a poorly understood institution, partly because scholars have come to associate the militia with militarism. However, the militia has important non-military functions and the interwar militia regiments were more than social clubs. This thesis compared the activities of two of Vancouver's militia regiments by examining their archival holdings to see if they had documentary evidence to support the notion that they functioned as a proto-fraternal society during the interwar period. The militia regiments functioned as fraternal associations providing mutual aid as well as congeniality. In the immediate post World War One period and during the Great Depression, with successively lower militia appropriations, militia regiments were forced out of necessity to come up with innovative ways to recruit and keep men on strength. Service in the militia was voluntary with members turning their pay back to the regiments to enable many of the militia regiments to function. The militia regiments held suppers and dances, and paid transportation costs to get members out for parade nights. The militia also played an integral role in the ceremonial life of the city. The ceremonial and symbolic values of militia units on parade were accepted features of public ceremonies in the city. It reaffirmed Vancouver's "Britishness." This thesis compares two of Vancouver's militia regiments during the interwar period, the Seaforth Highlanders of Canada and the British Columbia Regiment. The ethnic affiliation of the Seaforth Highlanders of Canada to the city's Scottish groups was a remarkable feature of Vancouver's elite unit. The militia allowed ambitious and patriotic young men to follow a British aristocratic career pattern: formal education at private schools, post-secondary training and military service. Militia regiments were part of an active social network within Vancouver between the wars. They conferred status, provided aid, and supported dominant values such as in Vancouver's society. This thesis provides some insight into the functioning of these two regiments as fraternal organizations and how they connected to the larger community.
Tracing the X-ray emitting intra-cluster medium of clusters of galaxies beyond r_200

description: (Abridged) We present in this paper a sample of 14 nearby clusters of galaxies observed with the ROSAT/PSPC. We only select clusters with low galactic nH in order to trace the X-ray emitting intra-cluster medium (ICM) out to large radii. We convert the X-ray surface brightness profiles of the clusters into emission measure profiles scaled to the classical scaling relations based on the spherical collapse model. We sort the clusters into different temperature bins and stack the scaled emission measure (ScEM) profiles of clusters together. The stacked profiles allow us to observe out to radii r>r_200. In the center we find that the ScEM profiles deviate from predicted scaling laws. This result is in very good agreement with current studies on the L_X-T relation and the entropy - temperature relation (S \propto T^0.65) found recently. At radii r>0.4r_200 we find that the ScEM profiles agree well within the error bars, suggesting self-similarity. Fitting beta-models to the overall ScEM profiles we find for the different sub samples r_c=0.15-0.18 r_200 and beta=0.8, which is higher than beta=2/3 often found. The beta-model is generally a better representation for hotter than for cooler clusters. We see indications for continuous steepening of the profiles with increasing radius: at radii r>0.8r_200 the profiles are systematically below the beta-model curve with beta=0.8. We discuss our results with respect to the observed X-ray luminosity L_X-T relation, the gas mass M_gas-T relation and the total mass M-T relation. We also address implications on the origin of the observed S-T relation. Furthermore we discuss the observed steepness of the X-ray profiles, which falls off more rapidly than predicted from the NFW-profile for cold dark matter halos.

We will also show how to take advantage of the field equations to anticipate the simple form of the constraints that we find in the paper.

description: Total poultry and red meat per capita consumption set new records almost every year between 1960 and 1992, chiefly due to increased poultry consumption. Red meat (mainly beef and pork) consumption peaked in 1971 and has declined since except for a small increase in 1992. However, per capita consumption of poultry nearly tripled, more than offsetting the 6-percent decline in red meat consumption. This report also contains (1) estimated prices that correspond with the three consumption measures, (2) definitions of price spreads and industry margins, and (3) costs between the farm and retail price of beef.

description: We review recent work on the use of the slice energy concept in generalized theories of gravitation. We focus on two special features in these theories, namely, the energy exchange between the matter component and the scalar field generated by the conformal transformation to the Einstein frame of such theories and the issue of the physical equivalence of different conformal frame representations. We show that all such conformally-related, generalized theories of gravitation allow for the slice energy to be invariably defined and its fundamental properties be insensitive to conformal transformations.

description: A novel probabilistic approach for the design of mechanical structures with friction interfaces is proposed. The objective function is defined as the probability that a specified performance measure of the forced vibration response is achieved subject to parameter uncertainties. The practicability of the approach regarding the extensive amount of required design evaluations is strictly related to the computational efficiency of the nonlinear dynamic analysis. Therefore, it is proposed to employ a recently developed parametric reduced order model (ROM) based on nonlinear modes of vibration, which can facilitate a decrease of the computational burden by several orders of magnitude. The approach was applied to a rotationally periodic assembly of a bladed disk with underplatform friction dampers. The robustness of the optimum damper design was significantly improved compared to the deterministic approach, taking into account uncertainties in the friction coefficient, the excitation level and the linear damping. Moreover, a scale invariance for piecewise linear contact constraints is proven, which can be very useful for the reduction of the numerical effort for the analysis of such systems.

description: This report documents the program and the outcomes of Dagstuhl Seminar 19331 ``Software Protection Decision Support and Evaluation Methodologies''. The seminar is situated in the domain of software protection against so-called man-at-the-end attacks, in which attackers have white-box access to the software that embeds valuable assets with security requirements such as confidentiality and integrity. The attackers try to compromise those by reverse-engineering the software and by tampering with it. Within this domain, the seminar focused mainly on three aspects: 1) how to evaluate newly proposed protections and attackers thereon; 2) how to create an appropriate benchmark suite to be used in such evaluations; 3) how to build decision support to aid users of protection tool with the selection of appropriate protections. The major outcomes are a structure for a white-paper on software protection evaluation methodologies, with some concrete input collected on the basis of four case studies explored during the seminar, and a plan for creating a software protection benchmark suite.

description: Dedicated, after acceptance and publication, in memory of the late Vassos Soteriou. For the first time, we leverage the 2.5D interposer technology to establish system-level security in the face of hardware- and software-centric adversaries. More specifically, we integrate chiplets (i.e., third-party hard intellectual property of complex functionality, like microprocessors) using a security-enforcing interposer. Such hardware organization provides a robust 2.5D root of trust for trustworthy, yet powerful and flexible, computation systems. The security paradigms for our scheme, employed firmly by design and construction, are: 1) stringent physical separation of trusted from untrusted components, and 2) runtime monitoring. The system-level activities of all untrusted commodity chiplets are checked continuously against security policies via physically separated security features. Aside from the security promises, the good economics of outsourced supply chains are still maintained; the system vendor is free to procure chiplets from the open market, while only producing the interposer and assembling the 2.5D system oneself. We showcase our scheme using the Cortex-M0 core and the AHB-Lite bus by ARM, building a secure 64-core system with shared memories. We evaluate our scheme through hardware simulation, considering different threat scenarios. Finally, we devise a physical-design flow for 2.5D systems, based on commercial-grade design tools, to demonstrate and evaluate our 2.5D root of trust.

description: We report on the realization of a strongly interacting quantum degenerate gas of fermionic atoms in a three-dimensional optical lattice. We prepare a band-insulating state for a two-component Fermi gas with one atom per spin state per lattice site. Using a Feshbach resonance, we induce strong interactions between the atoms. When sweeping the magnetic field from the repulsive side towards the attractive side of the Feshbach resonance we induce a coupling between Bloch bands leading to a transfer of atoms from the lowest band into higher bands. Sweeping the magnetic field across the Feshbach resonance from the attractive towards the repulsive side leads to two-particle bound states and ultimately to the formation of molecules. From the fraction of formed molecules we determine the temperature of the atoms in the lattice.

description: Even if nothing but a light Higgs is observed at the LHC, suggesting that the Standard Model is unmodified up to scales far above the weak scale, Higgs physics can yield surprises of fundamental significance for cosmology. As has long been known, the Standard Model vacuum may be metastable for low enough Higgs mass, but a specific value of the decay rate holds special significance: for a very narrow window of parameters, our Universe has not yet decayed but the current inflationary period can not be future eternal. Determining whether we are in this window requires exquisite but achievable experimental precision, with a measurement of the Higgs mass to 0.1 GeV at the LHC, the top mass to 60 MeV at a linear collider, as well as an improved determination of alpha_s by an order of magnitude on the lattice. If the parameters are observed to lie in this special range, particle physics will establish that the future of our Universe is a global big crunch, without harboring pockets of eternal inflation, strongly suggesting that eternal inflation is censored by the fundamental theory. This conclusion could be drawn even more sharply if metastability with the appropriate decay rate is found in the MSSM, where the physics governing the instability can be directly probed at the TeV scale.

description: This report documents the program and the outcomes of Dagstuhl Seminar 19351 ``Computational Proteomics''. The Seminar was originally built around four topics, identification and quantification of DIA data; algorithms for the analysis of protein cross-linking data; creating an online view on complete, browsable proteomes from public data; and detecting interesting biology from proteomics findings. These four topics were led to four correpsonding breakout sessions, which in turn led to five offshoot breakout sessions. The abstracts presented here first describe the four topic introduction talks, as well as a fifth, cross-cutting topic talk on bringin proteomics data into clinical trials. These talk abstracts are followed by one abstract each per breakout session, documenting that breakout's discussion and outcomes. An Executive Summary is also provided, which details the overall seminar structure, the relationship between the breakout sessions and topics, and the most important conclusions for the four topic-derived breakouts.

description: We study a class of superconductive radiation detectors in which the absorption of energy occurs in a long superconductive strip while the redout stage is provided by superconductive tunnel junctions positioned at the two ends of the strip. Such a device is capable both of imaging and energy resolution. In the established current scheme, well studied from the theoretical and experimental point of view, a fundamental ingredient is considered the presence of traps, or regions adjacent to the junctions made of a superconducting material of lower gap. We reconsider the problem by investigating the dynamics of the radiation induced excess quasiparticles in a simpler device, i.e. one without traps. The nonequilibrium excess quasiparticles can be seen to obey a diffusion equation whose coefficients are discontinuous functions of the position. Based on the analytical solution to this equation, we follow the dynamics of the quasiparticles in the device, predict the signal formation of the detector and discuss the potentiality offered by this configuration.

Survey of itinerant teachers of the deaf and hard of hearing in British Columbia, Canada
Creators: name: Williams, Christine Sybilla
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to gather information about the demographic variables and responsibilities of British Columbian itinerant teachers of the deaf and hard of hearing, investigate if these teachers experience occupational stress, determine the relationships between these variables and their stress levels, and to determine which manifestations of stress were most prevalent for this population. Two questionnaires were used in this study: the Teacher Stress Inventory (TSI), which was a standardized measure of stress, and the Itinerant Teacher Questionnaire (ITQ), which was a self-created questionnaire to gather information about demographics and itinerant responsibilities. The survey packages were mailed during the months of May and June 1998, to 92 itinerant teachers of the deaf and hard of hearing in BC, Canada. The response rate was 76% (n=70). The demographic information and responsibilities of the typical BC itinerant teacher of the deaf and hard of hearing were presented and discussed. This was the first project of its kind in BC to examine these variables, and it has created a database of information for further research and comparisons. Using the TSI and its norms, it was determined that BC itinerant teachers of the deaf and hard of hearing experience lower levels of stress than American teachers. However, caution should be exercised when comparing BC itinerant teachers to the norms, because the norms were collected from the northeast, mid-Atlantic, and southeastern states of the US. From the questionnaires and a multiple regression analysis, the predominant sources of stress for these teachers were determined to be: work overload, lack of time, high numbers of personnel worked with, poor ability to have rooms assigned in a school, poor quality of rooms worked in, weather interference during travel, and poor communication with school personnel. Using the TSI, emotional (anxious, depressed, etc.) and fatigue (physical exhaustion, weakness, etc.) manifestations of stress were the highest rated symptoms of stress experienced by BC itinerant teachers of the deaf and hard of hearing. Results, implications, concerns, and suggestions for further study are discussed.

Holographic Coulomb Branch Flows with N=1 Supersymmetry

Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We obtain a large, new class of N=1 supersymmetric holographic flow backgrounds with U(1)^3 symmetry. These solutions correspond to flows toward the Coulomb branch of the non-trivial N=1 supersymmetric fixed point. The massless (complex) chiral fields are allowed to develop vevs that are independent of their two phase angles, and this corresponds to allowing the brane to spread with arbitrary, U(1)^2 invariant, radial distributions in each of these directions. Our solutions are "almost Calabi-Yau:" The metric is hermitian with respect to an integrable complex structure, but is not Kahler. The "modulus squared" of the holomorphic (3,0)-form is the volume form, and the complete solution is characterized by a function that must satisfy a single partial differential equation that is closely related to the Calabi-Yau condition. The deformation from a standard Calabi-Yau background is driven by a non-trivial, non-normalizable 3-form flux dual to a fermion mass that reduces the supersymmetry to N=1. This flux also induces dielectric polarization of the D3-branes into D5-branes.

Massless Pseudoscalar Fields and Solution of the Federbush Model

description: The formal Heisenberg equations of the Federbush model are linearized and then are directly integrated applying the method of dynamical mappings. The fundamental role of two-dimensional free massless pseudo-scalar fields is revealed for this procedure together with their locality condition taken into account. Thus the better insight into solvability of this model is obtained together with the additional phase factor for its general solution, and the meaning of the Schwinger terms is elucidated.

description: We develop new strategies to build numerical relativity surrogate models for eccentric binary black hole systems, which are expected to play an increasingly important role in current and future gravitational-wave detectors. We introduce a new surrogate waveform model, \texttt{NRSur2dq1Ecc}, using 47 nonspinning, equal-mass waveforms with eccentricities up to $0.2$ when measured at a reference time of $5500M$ before merger. This is the first waveform model that is directly trained on eccentric numerical relativity simulations and does not require that the binary circularizes before merger. The model includes the $(2,2)$, $(3,2)$, and $(4,4)$ spin-weighted spherical harmonic modes. We also build a final black hole model, \texttt{NRSur2dq1EccRemnant}, which models the mass, and spin of the remnant black hole. We show that our waveform model can accurately predict numerical relativity waveforms with mismatches $\approx 10^{-3}$, while the remnant model can recover the final mass and dimensionless spin with absolute errors smaller than $\approx 5 \times 10^{-4}M$ and $\approx 2 \times10^{-3}$ respectively. We demonstrate that the waveform model can also recover subtle effects like mode-mixing in the ringdown signal without any special ad-hoc modeling steps. Finally, we show that despite being trained only on equal-mass binaries, \texttt{NRSur2dq1Ecc} can be reasonably extended up to mass ratio $q\approx3$ with mismatches $\simeq 10^{-2}$ for eccentricities smaller than $\sim 0.05$ as measured at a reference time of $2000M$ before merger. The methods developed here should prove useful in the building of future eccentric surrogate models over larger regions of the parameter space.

Inclination-Dependent Extinction Effects in Disk Galaxies in the Sloan Digital Sky Survey

description: We analyze the absolute magnitude (M_r) and color (u-r) of low redshift (z<0.06) galaxies in the Sloan Digital Sky Survey Data Release 6. galaxies with nearly exponential profiles (Sloan parameter fracDeV < 0.1) fall on the blue sequence of the color - magnitude diagram; if, in addition, these exponential galaxies have M_r < -19, they show a dependence of u-r color on apparent axis ratio q expected for a dusty disk galaxy. By fitting luminosity functions for exponential galaxies with different values of q, we find that the dimming is well described by the relation Delta M_r = 1.27 (log q)^2, rather than the Delta M = C log q law that is frequently assumed. When the absolute magnitudes of bright exponential galaxies are corrected to their "face-on" value, M_r^f = M_r - Delta M_r, the average u-r color is linearly dependent on M_r^f for a given value of q. Nearly face-on exponential galaxies (q > 0.9) have a shallow dependence of mean u-r color on M_r^f (0.096 magnitudes redder for every magnitude brighter). By comparison, nearly edge-on exponential galaxies (q < 0.3) are 0.265 magnitudes redder for every magnitude brighter. When the dimming law Delta M = 1.27 (log q)^2 is used to create an inclination-corrected sample of bright exponential galaxies, their apparent shapes are confirmed to be consistent with a distribution of mildly non-circular disks, with median short-to-long axis ratio gamma = 0.22 and median disk ellipticity epsilon = 0.08.

Creating deterministic collisions between two orbiting bodies
Creators: name: Munir, Akhtar
name: Sanders, Barry C.
Publisher: name: arXiv
Year: 2020
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: We aim to create deterministic collisions between orbiting bodies by applying a time-dependent external force to one or both bodies, whether the bodies are mutually repulsive, as in the two- or multi-electron atomic case or mutually attractive, as in the planetary-orbit case. Specifically, we have devised a mathematical framework for causing deterministic collisions by launching an inner orbiting body to a higher energy such that this inner body is guaranteed to collide with the outer body. Our method first expresses the problem mathematically as coupled nonlinear differential equations with a time-dependent driving force and solves to find a feasible solution for the force function. Although our calculation is based strictly on classical physics, our approach is suitable for the case of helium with two highly excited electrons and is also valid for creating collisions in the gravitational case such as for our solar system.

description: Excerpts from the Foreword: Nutrition: Eating for Good Health presents all aspects of nutrition for which the U.S. Department of Agriculture has responsibility, including nutrition guidance, Federal food assistance programs, and state-of-the-art research findings on what nutrients are needed by different groups in our society and how these nutrients affect our health and well-being. More than half of the U.S. Department of Agriculture's $68 billion budget is spent on nutrition programs. Some of these programs feed more than 25 million children lunch each school day or provide groceries for more than 27 million families through the Food Stamp program. This book was written and produced for those who are interested in eating for good health, and that includes most of us. It will be of special interest to people who work in the field of nutrition and meal planning, agricultural producers, educators, and students.
