description: We present an efficient algorithm to follow spectral evolution of Cosmic Rays (CR) coupled with an MHD system on Eulerian grids. The algorithm is designed for studies of CR energy spectrum evolution in MHD simulations of a galactic interstellar medium. The base algorithm for CR transport relies on the two-moment piece-wise power-law method, known also as Coarse Grained Momentum Final Volume (CGMV), for solving the Fokker-Planck CR transport equation, with a low number of momentum-bins extending over several decades of the momentum coordinate. We propose an extension of the CGMV with a novel feature which allows momentum boundaries to change in response to CR momentum gains or losses near the extremes of the population distribution. Our extension involves a special treatment of momentum bins containing spectral cutoff. Contrary to the regular bins of fixed width, those bins have variable-width, and their outer edges coincide with spectral cutoffs. The cutoff positions are estimated from the particle number density and energy density in the outer bins for an assumed small value of an additional parameter representing the smallest physically significant level of CR spectral energy density. We performed a series of elementary tests to validate the algorithm and demonstrated, whenever possible, that results of the test simulations correspond, with a reasonable accuracy, to the results of analogous analytical solutions. In a more complex test of galactic CR-driven wind problem we obtained results consistent with expectations regarding the effects of advection, diffusion, adiabatic, and synchrotron cooling of a CR population.

Search for exotic decays of the Higgs boson into long-lived particles in $pp$ collisions at $\sqrt{s} = 13$ TeV using displaced vertices in the ATLAS inner detector

description: A novel search for exotic decays of the Higgs boson into pairs of long-lived neutral particles, each decaying into a bottom quark pair, is performed using 139 fb$^{-1}$ of $\sqrt{s} = 13$ TeV proton-proton collision data collected with the ATLAS detector at the LHC. Events consistent with the production of a Higgs boson in association with a leptonically decaying $Z$ boson are analysed. Long-lived particle (LLP) decays are reconstructed from inner-detector tracks as displaced vertices with high mass and track multiplicity relative to Standard Model processes. The analysis selection requires the presence of at least two displaced vertices, effectively suppressing Standard Model backgrounds. The residual background contribution is estimated using a data-driven technique. No excess over Standard Model predictions is observed, and upper limits are set on the branching ratio of the Higgs boson to LLPs. Branching ratios above 10% are excluded at 95% confidence level for LLP mean proper lifetimes $cτ$ as small as 4 mm and as large as 100 mm. For LLP masses below 40 GeV, these results represent the most stringent constraint in this lifetime regime.

description: The dynamics of entanglement in `hybrid' non-unitary circuits (for example, involving both unitary gates and quantum measurements) has recently become an object of intense study. A major hurdle toward experimentally realizing this physics is the need to apply \emph{postselection} on random measurement outcomes in order to repeatedly prepare a given output state, resulting in an exponential overhead. We propose a method to sidestep this issue in a wide class of non-unitary circuits by taking advantage of \emph{spacetime duality}. This method maps the purification dynamics of a mixed state under non-unitary evolution onto a particular correlation function in an associated unitary circuit. This translates to an operational protocol which could be straightforwardly implemented on a digital quantum simulator. We discuss the signatures of different entanglement phases, and demonstrate examples via numerical simulations. With minor modifications, the proposed protocol allows measurement of the purity of arbitrary subsystems, which could shed light on the properties of the quantum error correcting code formed by the mixed phase in this class of hybrid dynamics.

description: We present singular value decomposition of spin correlation matrix defined from the ground state of one-dimensional antiferromagnetic quantum Heisenberg model. The decomposition creates a data set that coincides with various domain excitations from classical antiferromagnetic state. We determine the scaling relation for the singular values as a function of the domain size. The singular values are closely related to the square of weights of the bases in the ground-state wavefunction. The nature of the singular value decomposition is to precisely estimate the appropriate bases and corresponding weights of the ground-state wavefunction.

Prediction of acid rock drainage Red mountain project
Creators: name: Frostad, Scott
Publisher: name: University of British Columbia
Year: 2009

description: Mine waste planning and management is essential to minimize the environmental impacts resulting from the deposition of mine and milling wastes, particularly with respect to acid rock drainage (ARD). Kinetic tests such as humidity cells are widely used in an attempt to predict the rates of acid generation and neutralization, water quality and time to onset of acidity. Results from a kinetic prediction program to assist in the development of a waste management plan for the Red Mountain project in North-western British Columbia have been used to evaluate the effects of testing under a variety of controlled conditions and to make long term predictions. Results of laboratory tests conducted on samples with masses of 1 to 50 kg were compared to large scale (20-tonne) test results conducted at the mine site. Non-aerated cells provided rates of weathering that were similar to the standard humidity cells. The advantages of the non-aerated test protocol over the standard humidity cell include: • improved repeatability of results, • less expensive apparatus, • easier to operate, and • require less time to obtain rates of weathering. Increasing the volume of leach water did not influence the sulfate release rate, yet it increased the rate of neutralization potential (NP) depletion. The results indicate that water addition to kinetic tests must be sufficient to remove weathering products but must not be excessive that may artificially inflate NP depletion. The cumulative amount of Mg and Ca released at the point of acidity was greater for column tests than for humidity cells, which was attributed to the test protocol. Therefore, predicting time to acidity from estimates of NP depletion are questionable. Based on the testwork, time to acidity seems to relate better to measurements of cumulative sulfate release (acid production). Laboratory oxidation rates, corrected for surface area and temperature, could not be scaled up to predict the field results. Therefore extensive laboratory kinetic test programs that attempt to account for variations in waste pile rock types are considered unwarranted until the models used to scale-up laboratory data are validated. The large scale field tests produced results that were difficult to interpret and inconsistent when compared to the laboratory tests. In addition, field tests are prohibitively expensive and time consuming. Therefore, before conducting field tests, careful consideration of the expected results and test protocols is required.

description: We study totally umbilic isometric immersions between Riemannian manifolds. First, we provide a novel characterization of the totally umbilic isometric immersions with parallel normalized mean curvature vector, i.e., those having nonzero mean curvature vector and such that the unit vector in the direction of the mean curvature vector is parallel in the normal bundle. Such characterization is based on a family of curves, called planar pseudo-geodesics, representing a natural extrinsic generalization of both geodesics and Riemannian circles: being planar, their Cartan development in the tangent space is planar in the ordinary sense; being pseudo-geodesics, their geodesic and normal curvatures satisfy a linear relation. We study these curves in detail and, in particular, establish their local existence and uniqueness. Moreover, in the case of codimension-one immersions, we prove the following statement: an isometric immersion $ι\colon M \hookrightarrow Q$ is totally umbilic if and only if the extrinsic shape of every geodesic of $M$ is planar. This extends a well-known result about surfaces in $\mathbb{R}^{3}$.

description: Active Learning (AL) is an active domain of research, but is seldom used in the industry despite the pressing needs. This is in part due to a misalignment of objectives, while research strives at getting the best results on selected datasets, the industry wants guarantees that Active Learning will perform consistently and at least better than random labeling. The very one-off nature of Active Learning makes it crucial to understand how strategy selection can be carried out and what drives poor performance (lack of exploration, selection of samples that are too hard to classify, ...). To help rebuild trust of industrial practitioners in Active Learning, we present various actionable metrics. Through extensive experiments on reference datasets such as CIFAR100, Fashion-MNIST, and 20Newsgroups, we show that those metrics brings interpretability to AL strategies that can be leveraged by the practitioner.

description: The infrared behaviour of gluon and ghost propagators, ghost-gluon vertex and three-gluon vertex is investigated for both the covariant Landau and the non-covariant Coulomb gauge. Assuming infrared ghost dominance, we find a unique infrared exponent in the d=4 Landau gauge, while in the d=3+1 Coulomb gauge we find two different infrared exponents. We also show that a finite dressing of the ghost-gluon vertex has no influence on the infrared exponents. Finally, we determine the infrared behaviour of the three-gluon vertex analytically and calculate it numerically at the symmetric point in the Coulomb gauge.

description: This dissertation examines the development of women's activism in Pakistan since the early 1980's. It is a case study, which demonstrates the significance for the development of women's activism of the contingencies of the political and social context, and which explores the analytical value and political potential of different theoretical approaches to activism. A new framework for understanding women's activism is developed by answering four questions: How have political shifts and social contexts shaped women's activism? How have the personal backgrounds and experiences of activists shaped the trajectory of their activism? Why has much of women's activism focussed on high-profile incidents of gender violence and how have these incidents informed negotiations for change in gender relations? What does the future for women's activism look like in the light of the answers to these questions? Critics of women's activism in Pakistan assert that activists, who belong mainly to the elite, have acted to protect their own interests and failed to pursue an agenda that embraces the challenges that affect women from other social classes. Examining these critiques, the thesis reconceptualises women's activism as a recognition struggle that contests status and identity issues through its focus on the injustices suffered by all women because of discriminatory laws. This recognition struggle is enacted through patron-client relationships: activists as clients of the patron-state, relying on their connections with the state to promote an agenda for change, while simultaneously acting as patrons for other, less privileged women, enabling them to access the legal, political and social systems. The recognition struggle/patron-client paradigm exposes new relations of social and political subordination that activists have created, but it also demonstrates how activists have succeeded in diagnosing and responding to some of the structural roots of women's subordination. The efforts of these elite women activists show that another reality is possible -that all women can hope for a different future.

description: We give a new proof of a sumset conjecture of Furstenberg that was first proved by Hochman and Shmerkin in 2012: if $\log r / \log s$ is irrational and $X$ and $Y$ are $\times r$- and $\times s$-invariant subsets of $[0,1]$, respectively, then $\dim_\text{H} (X+Y) = \min ( 1, \dim_\text{H} X + \dim_\text{H} Y)$. Our main result yields information on the size of the sumset $λX + ηY$ uniformly across a compact set of parameters at fixed scales. The proof is combinatorial and avoids the machinery of local entropy averages and CP-processes, relying instead on a quantitative, discrete Marstrand projection theorem and a subtree regularity theorem that may be of independent interest.

description: We study kinetics of diffusion-limited catalytically-activated $A + B \to B$ reactions taking place in three dimensional systems, in which an annihilation of diffusive $A$ particles by diffusive traps $B$ may happen only if the encounter of an $A$ with any of the $B$s happens within a special catalytic subvolumen, these subvolumens being immobile and uniformly distributed within the reaction bath. Suitably extending the classical approach of Wilemski and Fixman (G. Wilemski and M. Fixman, J. Chem. Phys. \textbf{58}:4009, 1973) to such three-molecular diffusion-limited reactions, we calculate analytically an effective reaction constant and show that it comprises several terms associated with the residence and joint residence times of Brownian paths in finite domains. The effective reaction constant exhibits a non-trivial dependence on the reaction radii, the mean density of catalytic subvolumens and particles' diffusion coefficients. Finally, we discuss the fluctuation-induced kinetic behavior in such systems.

Oscillatory and tip-splitting instabilities in 2D dynamic fracture: The roles of intrinsic material length and time scales

description: Recent theoretical and computational progress has led to unprecedented understanding of symmetry-breaking instabilities in 2D dynamic fracture. At the heart of this progress resides the identification of two intrinsic, near crack tip length scales -- a nonlinear elastic length scale $\ell$ and a dissipation length scale $ξ$ -- that do not exist in the classical theory of cracks. In particular, it has been shown that at a high propagation velocity $v$, cracks in 2D brittle materials undergo an oscillatory instability whose wavelength varies linearly with $\ell$, and at yet higher propagation velocities and larger loading levels, a tip-splitting instability emerges, both in agreements with experiments. In this paper, using phase-field models of brittle fracture, we demonstrate the following properties of the oscillatory instability: (i) It exists also in the absence of near-tip elastic nonlinearity, i.e. in the limit $\ell\!\to\!0$, with a wavelength determined by the dissipation length scale $ξ$. This result shows that the instability crucially depends on the existence of an intrinsic length scale associated with the breakdown of linear elasticity near crack tips, independently of whether the latter is related to nonlinear elasticity or to dissipation. (ii) It is a supercritical Hopf bifurcation, featuring a vanishing oscillations amplitude at onset. (iii) It is largely independent of the fracture energy $Γ(v)$ that is controlled by a dissipation time scale. These results substantiate the universal nature of the oscillatory instability of ultra-high speed cracks in 2D. In addition, we provide evidence indicating that the ultra-high velocity tip-splitting instability is controlled by the limiting rate of elastic energy transport inside the crack tip region. Finally, we describe in detail the numerical implementation scheme of the employed phase-field fracture approach.

description: Motivated by recent progress in experimental techniques of electric dipole moment (EDM) measurements, we study correlations between the neutron and electron EDMs in common supersymmetric models. These include minimal supergravity (mSUGRA) with small CP phases, mSUGRA with a heavy SUSY spectrum, the decoupling scenario and split SUSY. In most cases, the electron and neutron EDMs are found to be observable in the next round of EDM experiments. They exhibit certain correlation patterns. For example, if d_n ~ 10^{-27} e cm is found, d_e is predicted to lie in the range 10^{-28}-10^{-29} e cm.

description: We show that some gapped quantum many-body systems have a ground state degeneracy that is stable to long-range (e.g., power-law) perturbations, in the sense that any ground state energy splitting induced by such perturbations is exponentially small in the system size. More specifically, we consider an Ising symmetry-breaking Hamiltonian with several exactly degenerate ground states and an energy gap, and we then perturb the system with Ising symmetric long-range interactions. For these models we prove (1) the stability of the gap, and (2) that the residual splitting of the low-energy states below the gap is exponentially small in the system size. Our proof relies on a convergent polymer expansion that is adapted to handle the long-range interactions in our model. We also discuss applications of our result to several models of physical interest, including the Kitaev p-wave wire model perturbed by power-law density-density interactions with an exponent greater than 1.

description: Long-Term visual localization under changing environments is a challenging problem in autonomous driving and mobile robotics due to season, illumination variance, etc. Image retrieval for localization is an efficient and effective solution to the problem. In this paper, we propose a novel multi-task architecture to fuse the geometric and semantic information into the multi-scale latent embedding representation for visual place recognition. To use the high-quality ground truths without any human effort, the effective multi-scale feature discriminator is proposed for adversarial training to achieve the domain adaptation from synthetic virtual KITTI dataset to real-world KITTI dataset. The proposed approach is validated on the Extended CMU-Seasons dataset and Oxford RobotCar dataset through a series of crucial comparison experiments, where our performance outperforms state-of-the-art baselines for retrieval-based localization and large-scale place recognition under the challenging environment.

description: We examine several assignments of spin and parity for the pentaquark Theta+ state (J^P=1/2^{+,-}, 3/2^{+,-}) in connection with known baryon resonances. Assuming that the Theta+ belongs to an antidecuplet representation which mixes with an octet, we calculate the mass spectra of the flavor partners of the Theta+ based on the SU(3) symmetry. The decay widths of the Theta+ and nucleon partners are analyzed for the consistency check of the mixing angle obtained from the masses. It is found that a suitable choice of the mixing angle successfully reproduces the observed masses of Theta(1540) and Xi_{3/2}(1860), when their spin and parity are assigned to be J^P=3/2^-, together with other J^P=3/2^- resonances. The decay widths of Theta -> KN, N(1520) -> pi N, and N(1700) -> pi N are also reproduced simultaneously.

This name includes material that is similar in morphology and close in size to those of the current Pt. deserta, Pt. feae, and Pt. cahow, so they could be included in any of these species. Nevertheless, it also remains possible (even probable) that they represent one or more cryptic unknown species (Figs 3, 4, 6, 7; Tables 2, 3, 4; Supporting Information, Figs S1–S8).
Material and collection information: See Supporting Information, Table S1.
Horizon: Late Quaternary–Recent.
Distribution: Porto dos Frades (Porto Santo, Madeira Archipelago), Madeira Island, and the Azores (São Miguel, Terceira, Graciosa, São Jorge, and Pico).
Remarks: The 14 C date of two fragments of ulna (proximal right and distal left) of one specimen of Pterodroma sp. B from Furna das Torres, Pico (Azores): RICH-21398 and 1654 ± 30 BP, was calibrated with 38 ± 139 (∆ R ± SD) providing the interval 665–1263 CE (Table 1). These bones are longer than those of the current Pt. madeira (Tables 2–4; Figs 3, 4, 6, 7). The ANOVA performed with the ulna lengths of the current Pt. madeira and those from these material [from Madeira Island, Porto dos Frades (Porto Santo), and Graciosa, Pico, and São Miguel (Azores)] indicate a smaller size of Pt. madeira bones (F 5,62 = 18 526; P <.001). The carpometacarpus from Madeira Island, Porto dos Frades (Porto Santo), Graciosa, and Pico are longer than those of the current Pt. madeira (U = –2.170; P =.03, U = –2.846; P =.004, U = –2.536; P =.011, and U = –2.449; P =.014, respectively). In addition, the ANOVA performed with the tarsometatarsus lengths of the current Pt. madeira and those of Pterodroma sp. B from the island of Madeira sites and from Porto Santo (Porto dos Frades) indicate a small size of the former (F 2,41 = 53 326; P <.001).
The material of this genus found in the Canary Islands (El Hierro) (Rando 2002) is of a similar size to those of this group (Tables 2, 4; Figs 3, 4, 6, 7). No differences were found in the carpometacarpus lengths between the fossil bones from El Hierro, the fossils from Pico (U = –0,816; P =.414), São Jorge (U = –0,655; P =.513), Porto dos Frades (U = –1528; P =.126), and the bones of the current specimens of Pt. cahow (U = –1061; P =.289) and Pt. deserta (U = –0,707; P =.48).

On the other hand, if the PBHs evaporate in the PBH dominated era, a quite heavy scotogenic dark matter ($m_{/rm DM} /gtrsim 10^9$ GeV) for $M_{/rm in}/M_{/rm Pl} /sim 10^{13}$ may be allowed.

description: We have examined the momentum expansion of the disk level S-matrix element of two tachyons and two gauge fields to find, up to on-shell ambiguity, the couplings of these fields in the world volume theory of N coincident non-BPS D-branes to all order of $α'$. Using the proposal that the action of D-brane-anti-D-brane is given by the projection of the action of two non-BPS D-branes with $(-1)^{F_L}$, we find the corresponding couplings in the world volume theory of the brane-anti-brane system. Using these infinite tower of couplings, we then calculate the massless pole of the scattering amplitude of one RR field, two tachyons and one gauge field in the brane-anti-brane theory. We find that the massless pole of the field theory amplitude is exactly equal to the massless pole of the disk level S-matrix element of one RR, two tachyons and one gauge field to all order of $α'$.

description: Pavarino proved that the additive Schwarz method with vertex patches and a low-order coarse space gives a $p$-robust solver for symmetric and coercive problems. However, for very high polynomial degree it is not feasible to assemble or factorize the matrices for each patch. In this work we introduce a direct solver for separable patch problems that scales to very high polynomial degree on tensor product cells. The solver constructs a tensor product basis that diagonalizes the blocks in the stiffness matrix for the internal degrees of freedom of each individual cell. As a result, the non-zero structure of the cell matrices is that of the graph connecting internal degrees of freedom to their projection onto the facets. In the new basis, the patch problem is as sparse as a low-order finite difference discretization, while having a sparser Cholesky factorization. We can thus afford to assemble and factorize the matrices for the vertex-patch problems, even for very high polynomial degree. In the non-separable case, the method can be applied as a preconditioner by approximating the problem with a separable surrogate. We demonstrate the approach by solving the Poisson equation and a $H(\mathrm{div})$-conforming interior penalty discretization of linear elasticity in three dimensions at $p = 15$.

description: We compute the magnetic field-induced modifications to the boson self-coupling and the boson-fermion coupling, in the static limit, using an effective model of QCD, the linear sigma model with quarks. The former is computed for arbitrary field strengths as well as using the strong field approximation. The latter is obtained in the strong field limit. The arbitrary field result for the boson self-coupling depends on the ultraviolet renormalization scale and this dependence cannot be removed by a simple vacuum subtraction. Using the strong field result as a guide, we find the appropriate choice for this scale and discuss the physical implications. The boson-fermion coupling depends on the Schwinger's phase and we show how this phase can be treated consistently in such a way that the magnetic field induced vertex modification is both gauge invariant and can be written with an explicit factor corresponding to energy-momentum conservation for the external particles. Both couplings show a modest decrease with the field strength.

description: Monte Carlo simulations, supplemented by ab initio calculations, shed light into the energetics and thermodynamic stability of nanostructured amorphous carbon. The interaction of the embedded nanocrystals with the host amorphous matrix is shown to determine in a large degree the stability and the relative energy differences among carbon phases. Diamonds are stable structures in matrices with sp^3 fraction over 60%. Schwarzites are stable in low-coordinated networks. Other sp^2-bonded structures are metastable.

description: Transport through quantum coherent conductors, like atomic junctions, is described by the distribution of conduction channels. Information about the number of channels and their transmission can be extracted from various sources, such as multiple Andreev reflections, dynamical Coulomb blockade, or shot noise. We complement this set of methods by introducing the superconducting excess current as a new tool to continuously extract the transport channel transmissions of an atomic scale junction in a scanning tunneling microscope. In conjunction with ab initio simulations, we employ this technique in atomic aluminum junctions to determine the influence of the structure adjacent to the contact atoms on the transport properties.

Structural Evaluation of Asphaltic Pavements

Subjects: subject: Transportation Engineering

description: To evaluate projects involving approximately 200 route-miles of interstate and primary pavements in Kentucky and Tennessee in relatively short time frames, it was decided to test, analyze, and design overlays using test equipment (Road Rater) and procedures developed by the University of Kentucky Transportation Research Program. This paper presents the analysis methodology and the evaluation and overlay designs for selected projects, including the before-and-after analysis of milling on one project.  The Road Rater applies a dynamic sinusoidal loading of known force and frequency. The velocity of the vibration waves are measured by sensors and integrated electronically to obtain surface deflections. An analysis of the shape and magnitude of the deflection bowl permits an assessment of whether the structure is performing as anticipated or whether some component is significantly weaker than designed. Analyses permit the determination of the ''behavioral'' or effective thicknesses of the asphaltic concrete layers and the in-place subgrade moduli. Strip charts of overlay thicknesses for each test point along the length of a project permit delineation of the project into relatively uniform segments. The required overlay thickness is the difference between the total thickness required for new construction to carry the anticipated traffic and the behavioral thickness of the existing pavement.

description: We will present the latest developments in CutLang, the runtime interpreter of a recently-developed analysis description language (ADL) for collider data analysis. ADL is a domain-specific, declarative language that describes the contents of an analysis in a standard and unambiguous way, independent of any computing framework. In ADL, analyses are written in human-readable plain text files, separating object, variable and event selection definitions in blocks, with a syntax that includes mathematical and logical operations, comparison and optimisation operators, reducers, four-vector algebra and commonly used functions. Adopting ADLs would bring numerous benefits to the LHC experimental and phenomenological communities, ranging from analysis preservation beyond the lifetimes of experiments or analysis software to facilitating the abstraction, design, visualization, validation, combination, reproduction, interpretation and overall communication of the analysis contents. Since their initial release, ADL and CutLang have been used for implementing and running numerous LHC analyses. In this process, the original syntax from CutLang v1 has been modified for better ADL compatibility, and the interpreter has been adapted to work with that syntax, resulting in the current release v2. Furthermore, CutLang has been enhanced to handle object combinatorics, to include tables and weights, to save events at any analysis stage, to benefit from multi-core/multi-CPU hardware among other improvements. In this contribution, these and other enhancements are discussed in details. In addition, real life examples from LHC analyses are presented together with a user manual.

description: We introduce a novel deep learning based group activity recognition approach called the Pose Only Group Activity Recognition System (POGARS), designed to use only tracked poses of people to predict the performed group activity. In contrast to existing approaches for group activity recognition, POGARS uses 1D CNNs to learn spatiotemporal dynamics of individuals involved in a group activity and forgo learning features from pixel data. The proposed model uses a spatial and temporal attention mechanism to infer person-wise importance and multi-task learning for simultaneously performing group and individual action classification. Experimental results confirm that POGARS achieves highly competitive results compared to state-of-the-art methods on a widely used public volleyball dataset despite only using tracked pose as input. Further our experiments show by using pose only as input, POGARS has better generalization capabilities compared to methods that use RGB as input.

description: We hereby derive the Newtonian metric potentials for the fourth-derivative gravity including the one-loop logarithm quantum corrections. It is explicitly shown that the behavior of the modified Newtonian potential near the origin is improved respect to the classical one, but this is not enough to remove the curvature singularity in $r=0$. Our result is grounded on a rigorous proof based on numerical and analytic computations.

description: The objective of this study is-to evaluate the effectiveness of the traffic noise barrier on I 471 in Campbell County, Kentucky. Since the barrier construction coincided with construction of I 471, it was necessary to predict noise levels that would exist if no barrier were present by utilizing the FHWA STAMINA 2.0 computer model. This was compared to actual noise level measurements at the barrier site in order to determine the barrier insertion loss.  After calibration of the STAMINA 2.0 model, initial field measurements were taken at receiver locations throughout the barrier site. The average insertion loss in Leq was found to be 7.0 dBA, ranging from 3.5 dBA to 13.0 dBA. The average insertion loss in L10 was found to be 8.2 dBA, ranging from 5.0 dBA to 14.3 dBA.  A questionnaire to be used in a community perception survey was developed. The survery will be distributed and the results summarized in the final report.
