description: We present an efficient algorithm for calculating the properties of Ising models in two dimensions, directly in the spin basis, without the need for mapping to fermion or dimer models. The algorithm gives numerically exact results for the partition function and correlation functions at a single temperature on any planar network of N Ising spins in O(N^{3/2}) time or less. The method can handle continuous or discrete bond disorder and is especially efficient in the case of bond or site dilution, where it executes in O(L^2 ln L) time near the percolation threshold. We demonstrate its feasibility on the ferromagnetic Ising model and the +/- J random-bond Ising model (RBIM) and discuss the regime of applicability in cases of full frustration such as the Ising antiferromagnet on a triangular lattice.

Long-term potentiation and mathematical analysis of electrical models of dendritic spines
Creators: name: Thiara, Rajpal Singh
Publisher: name: University of British Columbia
Year: 2009

description: Dendritic spines are small evaginations of the dendrites of neurons first discovered late in the 19th century. Since their discovery, many theories have been put forth to explain the physiological role of the spine. However, only recently with the advent of new laboratory technology has data been available to test the various theories put forward. The two most compelling theories today are that spines are important mediators of a form of cellular memory known as long-term potentiation (LTP), and that spines may be involved in the conduction of regenerative electrical impulses within dendrites similar to action potentials in axons. We will review some of the major mathematical models put forth which attempt to explain the role spines may play in the induction of LTP. We will address the importance of calcium signals in LTP induction and suggest how the unique morphology of the spine may allow for transient, spatially localized increases in calcium within the spine head, but not elsewhere in the dendrite. This could help account for the associativity, cooperativity, and input specificity requirements of LTP. We will also review some of the major mathematical models on dendritic action potentials. These models generally assume the existence of voltage-gated ion channels with Hodgkin-Huxley (HH) type dynamics exist in the spine head. We will employ a continuum approach in which spines are modeled as having a certain uniform density. We will further make use of the FitzHugh-Nagumo (FHN) equations without recovery to approximate the HH equations. We will examine the new set of equations in the traveling wave frame and seek to determine how the various parameters influence the speed, and the shape of the traveling wave front solutions. We show that there is a certain balance between local excitation of the spine heads, and freedom for the electrical current to pass from spine head to dendrite required for traveling front solutions to exist. Furthermore, strict parameter spaces in which traveling front solutions exist are determined, as is the profile of the wave in the special case of a standing wave.

description: We study the dynamics of a reaction-diffusion system composed of two mutually coupled excitable fibers. We focus on the situation in which dynamical properties of the two fibers are not identical because of the parameter difference between the fibers. Using the spatially one-dimensional FitzHugh-Nagumo equations as a model of a single excitable fiber, we show that the system exhibits a rich variety of dynamical behavior, including soliton-like collision between two pulses, recombination of a solitary pulse and synchronized pulses, and overtaking of a slow-moving solitary pulse by fast-moving synchronized pulses.

description: We suggest that the transition that occurs at large $N_c$ in the eigenvalue distribution of a Wilson loop may have a turbulent origin. We arrived at this conclusion by studying the complex-valued inviscid Burgers-Hopf equation that corresponds to the Makeenko-Migdal loop equation, and we demonstrate the appearance of a shock in the spectral flow of the Wilson loop eigenvalues. This picture supplements that of the Durhuus-Olesen transition with a particular realization of disorder. The critical behavior at the formation of the shock allows us to infer exponents that have been measured recently in lattice simulations by Narayanan and Neuberger in $d=2$ and $d=3$. Our analysis leads us to speculate that the universal behavior observed in these lattice simulations might be a generic feature of confinement, also in $d=4$ Yang-Mills theory.

description: Collective (elementary) excitations of quantum bosonic condensates, including condensates of exciton polaritons in semiconductor microcavities, are a sensitive probe of interparticle interactions. In anisotropic microcavities with momentum-dependent TE-TM splitting of the optical modes, the excitations dispersions are predicted to be strongly anisotropic, which is a consequence of the synthetic magnetic gauge field of the cavity, as well as the interplay between different interaction strengths for polaritons in the singlet and triplet spin configurations. Here, by directly measuring the dispersion of the collective excitations in a high-density optically trapped exciton-polariton condensate, we observe excellent agreement with the theoretical predictions for spinor polariton excitations. We extract the inter- and intra-spin polariton interaction constants and map out the characteristic spin textures in an interacting spinor condensate of exciton polaritons.
A Significant Population of Very Luminous Dust-Obscured Galaxies at Redshift z ~ 2

description: Observations with Spitzer Space Telescope have recently revealed a significant population of high-redshift z~2 dust-obscured galaxies (DOGs) with large mid-IR to UV luminosity ratios. These galaxies have been missed in traditional optical studies of the distant universe. We present a simple method for selecting this high-z population based solely on the ratio of the observed mid-IR 24um to optical R-band flux density. In the 8.6 sq.deg Bootes NDWFS Field, we uncover ~2,600 DOG candidates (= 0.089/sq.arcmin) with 24um flux densities F24>0.3mJy and (R-[24])>14 (i.e., F[24]/F[R] > 1000). These galaxies have no counterparts in the local universe, and become a larger fraction of the population at fainter F24, representing 13% of the sources at 0.3~mJy. DOGs exhibit evidence of both star-formation and AGN activity, with the brighter 24um sources being more AGN- dominated. We have measured spectroscopic redshifts for 86 DOGs, and find a broad z distribution centered at ~2.0. Their space density is 2.82E-5 per cubic Mpc, similar to that of bright sub-mm-selected galaxies at z~2. These redshifts imply very large luminosities LIR>~1E12-14 Lsun. DOGs contribute ~45-100% of the IR luminosity density contributed by all z~2 ULIRGs, suggesting that our simple selection criterion identifies the bulk of z~2 ULIRGs. DOGs may be the progenitors of ~4L* present-day galaxies seen undergoing a luminous,short- lived phase of bulge and black hole growth. They may represent a brief evolution phase between SMGs and less obscured quasars or galaxies. [Abridged]

description: We identify a valley-polarized Chern insulator in the van der Waals heterostructure, Pt$_{2}$HgSe$_{3}$/CrI$_3$, for potential applications with interplay between electric, magnetic, optical, and mechanical effects. The interlayer proximity magnetic coupling nearly closes the band gap of Pt$_{2}$HgSe$_{3}$ and the strong intra-layer spin-orbit coupling further lifts the valley degeneracy by over 100 meV leading to positive and negative band gaps at opposite valleys. In the valley with negative gap, the interfacial Rashba spin-orbit coupling opens a topological band gap of 17.8 meV, which is enlarged to 30.8 meV by adding an $h$-BN layer. We find large orbital magnetization in Pt$_{2}$HgSe$_{3}$ layer that is much larger than spin, which can induce measurable optical Kerr effect. The valley polarization and Chern number are coupled to the magnetic order of the nearest neighboring CrI$_3$ layer, which is switchable by electric, magnetic, and mechanical means in experiments. The presence of $h$-BN protects the topological phase allowing the construction of superlattices with valley, spin, and layer degrees of freedoms.

description: We demonstrate an efficient eigen-decomposition method for analyzing the guided modes in metal nanoparticle chains. The proposed method has the advantage of showing the dispersion relation and mode quality simultaneously. It can also separate the material and geometrical properties, so its efficiency does not depend on the complexity of the material polarizability. The method is applied to analyze the guided modes of a single and a pair of metal chains. The more accurate dynamic dipole polarizability typically gives a red-shift compared with the results obtained with the broadly used quasistatic dipole polarizability with radiation correction.

description: We present the first measurements of cyclotron resonance of electrons and holes in bilayer graphene. In magnetic fields up to B = 18 T we observe four distinct intraband transitions in both the conduction and valence bands. The transition energies are roughly linear in B between the lowest Landau levels, whereas they follow \sqrt{B} for the higher transitions. This highly unusual behavior represents a change from a parabolic to a linear energy dispersion. The density of states derived from our data generally agrees with the existing lowest order tight binding calculation for bilayer graphene. However in comparing data to theory, a single set of fitting parameters fails to describe the experimental results.

description: In the $e^+e^-$ annihilation processes $e^+e^-\to D^0\bar{D}^0, D^+D^-$ near or above the threshold of $D\bar{D}$, there are not only the resonance contribution $e^+e^-\to ψ(3770)\to D^0\bar{D}^0, D^+D^-$, but also the continuum contribution through virtual photon directly $e^+e^-\to γ^*\to D^0\bar{D}^0, D^+D^-$. The amplitudes through virtual photon directly and through resonance can interfere seriously. We consider the continuum and interference effect in the $D\bar{D}$ production process in $e^+e^-$ annihilation. We find that the effect is significant near and above the threshold of the $D\bar{D}$ mesons.

Analysis of cyclic reduction for the numerical solution of three-dimensional convection-diffusion equations
Creators: name: Greif, Chen
Publisher: name: University of British Columbia
Year: 2009

description: This thesis deals with the numerical solution of convection-diffusion equations. In particular, the focus is on the analysis of applying one step of cyclic reduction to linear systems of equations which arise from finite difference discretization of steady-state three-dimensional convection-diffusion equations. The method is based on decoupling the unknowns and solving the resulting smaller linear systems using iterative methods. In three dimensions this procedure results in some loss of sparsity, compared to lower dimensions. Nevertheless, the resulting linear system has excellent numerical properties, is generally better conditioned than the original system, and gives rise to faster convergence of iterative solvers, and convergence in cases where solvers of the original system of equations fail to converge. The thesis starts with an overview of the equations that are solved and general properties of the resulting linear systems. Then, the unsymmetric discrete operator is derived and the structure of the cyclically reduced linear system is described. Several important aspects are analyzed in detail. The issue of orderings is addressed and a highly effective ordering strategy is presented. The complicated sparsity pattern of the matrix requires careful analysis; comprehensive convergence analysis for block stationary methods is provided, and the bounds on convergence rates are shown to be very tight. The computational work required to perform cyclic reduction and compute the solution of the linear system is discussed at length. Preconditioning techniques and various iterative solvers are considered.

description: We review recent developments in understanding quantum/string corrections to BPS black holes and strings in five-dimensional supergravity. These objects are solutions to the effective action obtained from M-theory compactified on a Calabi-Yau threefold, including the one-loop corrections determined by anomaly cancellation and supersymmetry. We introduce the off-shell formulation of this theory obtained through the conformal supergravity method and review the methods for investigating supersymmetric solutions. This leads to quantum/string corrected attractor geometries, as well as asymptotically flat black strings and spinning black holes. With these solutions in hand, we compare our results with analogous studies in four-dimensional string-corrected supergravity, emphasizing the distinctions between the four and five dimensional theories.

description: Surface lithium abundance and rotation velocity can serve as powerful and mutually complementary diagnostics of interior structure of stars. So far, the processes responsible for the lithium depletion during pre-main sequence evolution are still poorly understood. We investigate whether a correlation exists between equivalent widths of Li (EW(Li)) and rotation period (P$_{rot}$) for Weak-line T Tauri stars (WTTSs). We find that rapidly rotating stars have lower EW(Li) and the fast burning of Li begins at the phase when star's P$_{rot}$ evolves towards 3 days among 0.9M$_\odot$ to 1.4M$_\odot$ WTTSs in Taurus-Auriga. Our results support the conclusion by Piau & Turch-Chiéze about a model for lithium depletion with age of the star and by Bouvier et al. in relation to rotation evolution. The turn over of the curve for the correlation between EW(Li) and P$_{rot}$ is at the phase of Zero-Age Main Sequence (ZAMS). The EW(Li) decreases with decreasing P$_{rot}$ before the star reaches the ZAMS, while it decreases with increasing P$_{rot}$ (decreasing rotation velocity) for young low-mass main sequence stars. This result could be explained as an age effect of Li depletion and the rapid rotation does not inhibit Li destruction among low mass PMS stars.

Year: 1992
Subjects: subject: Transportation Engineering

description: This report summarizes findings of laboratory and field trial evaluations of two experimental test sections constructed adjacent to one another. One experimental section contained a mixture of pulverized fuel ash, residue from an atmospheric fluidized bed combustion process, and limestone aggregate. The second section contained a similar mixture but included a small amount of Type Ill cement. Both experimental sections were constructed to a total nominal thickness of nine inches. The typical design section included six inches of the experimental mixtures, used as base materials, beneath three inches asphaltic concrete. A previous report documented construction of the test sections and preliminary performance evaluations or the experimental base mixtures (UKTRP 87·15).  Analyses of additional periodic deflection testing are detailed within this report. The experimental sections were monitored over a three year period. It was concluded, based upon performance observations and evaluation activities, that both experimental mixtures are suitable for use as a road base material. Both test sections performed well with no cracking, rutting or unexpected deterioration observed. Results of the deflection testing activities indicated that the pavement structure containing cement had somewhat higher stiffness values and generally maintained those values over time.

description: In this article, we assume that there exist the pseudoscalar $D\bar{D}_{s0}^*(2317)$ and $D^*\bar{D}_{s1}^*(2460)$ molecular states $Z_{1,2}$ and construct the color singlet-singlet molecule-type interpolating currents to study their masses with the QCD sum rules. In calculations, we consider the contributions of the vacuum condensates up to dimension-10 and use the formula $μ=\sqrt{M_{X/Y/Z}^{2}-\left(2{\mathbb{M}}_{c}\right)^{2}}$ to determine the energy scales of the QCD spectral densities. The numerical results, $M_{Z_1}=4.61_{-0.08}^{+0.11}\,\text{GeV}$ and $M_{Z_2}=4.60_{-0.06}^{+0.07}\,\text{GeV}$, which lie above the $D\bar{D}_{s0}^*(2317)$ and $D^*\bar{D}_{s1}^*(2460)$ thresholds respectively, indicate that the $D\bar{D}_{s0}^*(2317)$ and $D^*\bar{D}_{s1}^*(2460)$ are difficult to form bound state molecular states, the $Z_{1,2}$ are probably resonance states.

Summary of Results of 1991 Field and Laboratory Evaluations of Pavement Marking Materials

Year: 1992
Subjects: subject: Transportation Engineering

description: This report summarizes the results of data collected as part of the 1991 field and laboratory evaluations of pavement marking materials for the SASHTO Regional Test Facility.The purpose of the Regional Test Facility (RTF) is to minimize the amount of field and laboratory research testing of specific types of materials. This is accomplished by combining efforts in an organized manner to reduce the monetary and man-hour requirements of both the states and industry. A RTF for the twelve SASHTO states was approved at the 1988 SASHTO convention. The twelve SASHTO states are Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, and West Virginia.  The SASHTO Regional Test Facility (SRTF) began operation in November 1988 when informational packets were mailed to all known manufacturers of four types of material. One type of material included in the test is classified as striping materials. To be included in the test, the manufacturers has until 5:00 p.m. at the end of the first working day in January to submit a Product Evaluation Form, a check for the testing fee, sample materials, and other pertinent information to the coordinator of the SRTF in order to have their product considered for inclusion in the testing process for that calendar year. A testing fee of $2,000 per sample was originally established for the striping materials. This fee covered the cost of performing the required field and laboratory tests and reporting the results. This fee was reduced to $1,500 per sample starting with the 1991 test.  Different states were selected to perform the tests for the various materials. For the striping materials, Kentucky was selected as the lead state responsible for reporting the results. Alabama was selected as the support state. Identical field installations were placed in Kentucky and Alabama in 1989 and 1990. However, beginning in 1991, the field tests began operating on an alternating basis. The materials submitted for testing in 1991 were placed in Kentucky in 1991 and in Alabama in 1992. The laboratory tests were performed by Louisiana. The Transportation Center at the University of Kentucky performed the work in Kentucky for the Kentucky Transportation Cabinet. The Alabama Highway Department conducted the field tests in Alabama while the Louisiana Department of Transportation performed the laboratory tests in Louisiana.  This report is the third summary of field and laboratory evaluations of pavement marking materials at the SASHTO Regional Test Facility. The previous summaries dealt with the 1989 and 1990 evaluations. The data in this report are for a one-year period for materials placed in Kentucky in 1991 and a two-year period for the longer life materials (such as thermoplastics and nonremovable tape) placed in Kentucky and Alabama in 1990.

Design and Performance of a Bituminous Surface Mixture Containing Bottom Ash Aggregate
Creators: name: Hunsucker, David Q.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1992
Subjects: subject: Transportation Engineering

description: A one-mile experimental bituminous surface overlay was placed in October 1987 on State Route 3 in Lawrence County, Kentucky. The experimental section utilized bottom ash aggregate from the Kentucky Power Company's Big Sandy Power Plant, near Louisa, Kentucky. Bottom ashes are generally angular and have very porous surfaces. Approximately 539 tons of the experimental bituminous surface material, containing 40 percent bottom ash (dry weight), were placed. Reported herein are results of laboratory tests and performance evaluations of the experimental surface mixture.  Performance of the experimental bottom ash surface has been excellent. Skid resistance tests indicate the surface is highly skid resistant. Bottom ash represents a large potential source of high-friction, nonpolishing aggregate that may be successfully substituted for a portion of the coarse aggregate in a bituminous surface mixture.

description: We study a three-mode Hamiltonian modelling a heteronuclear molecular Bose--Einstein condensate. Two modes are associated with two distinguishable atomic constituents, which can combine to form a molecule represented by the third mode. Beginning with a semi-classical analogue of the model, we conduct an analysis to determine the phase space fixed points of the system. Bifurcations of the fixed points naturally separate the coupling parameter space into different regions. Two distinct scenarios are found, dependent on whether the imbalance between the number operators for the atomic modes is zero or non-zero. This result suggests the ground-state properties of the model exhibit an unusual sensitivity on the atomic imbalance. We then test this finding for the quantum mechanical model. Specifically we use Bethe ansatz methods, ground-state expectation values, the character of the quantum dynamics, and ground-state wavefunction overlaps to clarify the nature of the ground-state phases. The character of the transition is smoothed due to quantum fluctuations, but we may nonetheless identify the emergence of a quantum phase boundary in the limit of zero atomic imbalance.

description: Supplemental material, tables and figure for manuscript titled "Short Stature is Progressive in Patients with Heterozygous NPR2 Mutations"
Abstract:
Background: NPR2 encodes natriuretic peptide receptor B (NPR-B), a regulator of skeletal growth. Homozygous loss-of-function mutations in NPR2 result in acromesomelic dysplasia Maroteaux type (AMDM; OMIM 602875), while heterozygous mutations may account for 2-6% of idiopathic short stature (ISS).
Objective: Describe the physical proportions and growth characteristics of an extended family with novel NPR2 mutations including members with AMDM, ISS, or normal stature.
Design and Participants: We performed whole exome sequencing in two healthy parents and two children with AMDM. Detailed genotyping and phenotyping was performed on members of a multigenerational family in an academic medical center. We expressed mutant proteins in mammalian cells and characterized expression and function.
Results: The sisters with AMDM were compound heterozygotes for two novel missense mutations in the NPR2 gene, p.P93S (maternal) and p.R989L (paternal), which lack catalytic function. Heterozygous relatives had proportionate short stature (height z-scores -2.06 ± 0.97, median ± SD) compared to their wild type siblings (-1.37 ± 0.59). Height z-scores progressively and significantly decreased as NPR2 heterozygous children aged, while it remained consistent in their wild type siblings.
Conclusions: Biallelic NPR2 mutations cause severe skeletal dysplasia (ADMD), whereas heterozygous mutations lead to a subtler phenotype characterized by progressive short stature and increasing loss of height potential with age.
Précis: Study of family including children with AMDM and short stature from novel NPR2 mutations. Subjects with heterozygous mutations showed progressive short stature and loss of height potential with age.

description: We prove a more general version of the Gruss inequality by using the recent theory of combined dynamic derivatives on time scales and the more general notions of diamond-alpha derivative and integral. For the particular case when alpha = 1, one gets a delta-integral Gruss inequality on time scales; for alpha = 0 a nabla-integral Gruss inequality. If we further restrict ourselves by fixing the time scale to the real (or integer) numbers, then the standard continuous (discrete) inequalities are obtained.

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1992
Subjects: subject: Transportation Engineering

description: This report summarizes findings of laboratory and construction evaluations of using residue from an atmospheric fluidized bed combustion (AFBC) process as a component in an experimental road base and subbase application. The base mixture contains pulverized fuel ash, AFBC residue, and limestone aggregates used as bulk filler. The subbase mixture contains AFBC residue and pond ash (ponded fly ash and bottom ash). Mixtures containing various proportions of each component were evaluated in the laboratory relative to maximum dry density, optimum moisture content, and compressive strength development.  Two 750-foot test sections of a 22-foot wide roadway, containing the experimental mixtures, were constructed in May and June 1988. Prior to construction, in-place California Bearing Ratio tests, moisture content determinations and Road Rater deflection tests were performed on the prepared subgrade. During construction of the experimental base and subbase layers, relative compaction and moisture contents of the materials were monitored by nuclear devices. Specimens were compacted for subsequent evaluations. Initial post-construction evaluations included compressive strength development, elastic modulus, Road Rater deflection analyses, and monitoring expansion of the experimental mixtures both in the field and in the laboratory.

description: The coincidental detection of the gravitational wave event GW 170817 and the associated gamma-ray burst GRB 170817A marked the advent of multi-messenger astronomy and represented a milestone in the study of GRBs. In this context, the launch of SVOM in mid-2022, with its two wide-field high-energy instruments ECLAIRs and GRM, will foster the possibilities of coincidental transient detection with gravitational waves and gamma-rays events. The purpose of this paper is to assess the ability of SVOM/ECLAIRs to detect and quickly characterize high-energy transients in the local Universe (z<0.3), and to discuss the contribution of this instrument to multi-messenger astronomy and to gamma-ray burst(GRB) astrophysics in the 2020s. A list of local HE transients, along with their main characteristics, is constructed through an extensive literature survey. The detectability of these transients with ECLAIRs is assessed with detailed simulations using tools developed for the SVOM mission, including a GEANT4 simulation of the energy response and a simulated trigger algorithm representative of the onboard trigger algorithm. The SNR for almost all detections will be sufficiently high to allow the on-board ECLAIRs trigger algorithm to detect and derive the localisation of the transient, transmitting it to the SVOM satellite and ground-based instruments. Coupled with the anti-solar pointing strategy of SVOM, this will enable an optimal follow-up of the events, allowing the observation of their afterglows, supernovae/kilonovae counterparts, and host galaxies. We conclude the paper with a discussion of the unique contribution expected from SVOM and of the possibility of simultaneous GW detection for each type of transient in our sample.

description: In this paper we present calculations of single-particle excitation spectra of neutral and three-electron-doped Hubbard C$_{60}$ molecules and monolayers from large-scale quantum Monte Carlo simulations and cluster perturbation theory. By a comparison to experimental photoemission, inverse photoemission, and angle-resolved photoemission data, we estimate the intermolecular hopping integrals and the C$_{60}$ molecular orientation angle, finding agreement with recent X-ray photoelectron diffraction (XPD) experiments. Our results demonstrate that a simple effective Hubbard model, with intermediate coupling, $U=4t$, provides a reasonable basis for modeling the properties of C$_{60}$ compounds.

Contact mechanics using Green's functions for interactive simulated environments
Creators: name: Ullrich, C.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is concerned with the determination of contact models for linear elastic solids which are both accurate and computable in a real time environment. We review previous models based on restitution coefficients and penalty functions, along with their efficiency and accuracy. A new model is proposed which is both rapidly computable and based on easily measurable material properties. In addition, we consider the role that friction plays in contact modeling and examine the various friction based effects that each model can produce. We conclude by outlining a simulation system in which this model can be used.
