description: We exploit the superb resolution of the new HST/ACS mosaic image of M51 to select a large sample of young (< 1 Gyr) star clusters in the spiral disk, based on their sizes. The image covers the entire spiral disk in B, V, I and H_alpha, at a resolution of 2 pc per pixel. The surface density distribution of 4357 resolved clusters shows that the clusters are more correlated with clouds than with stars, and we find a hint of enhanced cluster formation at the corotation radius. The radius distribution of a sample of 769 clusters with more accurate radii suggests that young star clusters have a preferred effective radius of ~3 pc, which is similar to the preferred radius of the much older GCs. However, in contrast to the GCs, the young clusters in M51 do not show a relation between radius and galactocentric distance. This means that the clusters did not form in tidal equilibrium with their host galaxy, nor that their radius is related to the ambient pressure.

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 2006
Subjects: subject: Transportation Engineering

description: This study addresses experimental evaluation and testing of concrete coatings for maintenance purposes on structural (steel reinforced) concrete. The test methods employed are intended to identify coatings and sealers for eventual incorporation into a qualified products list for structural concrete coatings. Some of the methods/procedures used in this study will be used in the future to evaluate additional coatings and sealers. Developmental work focused on identifying relevant coatings systems and laboratory tests. The objectives of experimental project monitoring were to: 1) identify existing viable concrete coatings along with their properties/ characteristics/surface preparation requirements and determine effective acceptance/evaluation tests for those coatings; 2) provide a compendium of concrete coatings/properties/tests for consideration by KYTC; 3) evaluate laboratory tests of promising concrete coatings and develop new test procedures if existing ones prove unacceptable for KYTC purposes; 4) use those tests to evaluate KYTC-approved coatings; 5) conduct field tests of candidate coatings on existing structures; and 6) provide KYTC with a range of effective concrete bridge coatings and guidelines for selecting them to provide the best benefits to bridges. This report provides a summary of the coatings systems tested and the overall results/findings of this research study.
Using Unreal Engine to Visualize a Cosmological Volume

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: In this work we present `Astera', a cosmological visualization tool that renders a mock universe in real time using Unreal Engine 4. The large scale structure of the cosmic web is hard to visualize in two dimensions, and a 3D real time projection of this distribution allows for an unprecedented view of the large scale universe, with visually accurate galaxies placed in a dynamic 3D world. The underlying data are based on empirical relations assigned using results from N-Body dark matter simulations, and are matched to galaxies with similar morphologies and sizes, images of which are extracted from the Sloan Digital Sky Survey. Within Unreal Engine 4, galaxy images are transformed into textures and dynamic materials (with appropriate transparency) that are applied to static mesh objects with appropriate sizes and locations. To ensure excellent performance, these static meshes are `instanced' to utilize the full capabilities of a graphics processing unit. Additional components include a dynamic system for representing accelerated-time active galactic nuclei. The end result is a visually realistic large scale universe that can be explored by a user in real time, with accurate large scale structure. Astera is not yet ready for public release, but we are exploring options to make different versions of the code available for both research and outreach applications.

description: We consider intersecting D-brane models which have two dimensional chiral fermions localized at the intersections. At weak coupling, the interactions of these fermions are described by generalized Gross-Neveu models. At strong coupling, these configurations are described by the dynamics of probe D-branes in a curved background spacetime. We study patterns of dynamical chiral symmetry breaking in these models at weak and strong coupling, and also discuss relationships between these two descriptions.

description: We investigate whether certain extra-solar multi-planet systems simultaneously follow the scaling and spacing rules of the angular-momentum-deficit model. The masses and semi-major axes of exoplanets in ten multi-planet systems are considered. It is found that GJ 667C, HD 215152, HD 40307, and Kepler-79 systems are currently close to configurations of the angular-momentum-deficit model. In a gas-poor scenario, GJ 3293, HD 141399, and HD 34445 systems are those which had a configuration of the angular-momentum-deficit model in the past and get scattered away due to post gaseous effects. In addition, no matter in gas-free or gas-poor scenario, 55 Cnc, GJ 876, and WASP-47 systems do not follow the angular-momentum-deficit model. Therefore, our results reveal important formation histories of these multi-planet systems.

description: In this paper we briefly review the main idea of the localization technique and its extension suitable in supersymmetric gauge field theory. We analyze the partition function of the vector multiplets with supercharges and its blocks on the even- and odd-dimensional spheres and squashed spheres. We exploit so-called Faà di Bruno's formula and show that multipartite partition functions can be written in the form of expansion series of the Bell polynomials. Applying the restricted specialization argument we show that $q$-infinite-product representation of partition functions admits presentation in terms of the Patterson-Selberg (or the Ruelle-type) spectral functions.

description: This paper concerns sprinklings into Minkowski space (Poisson processes). It proves that there exists no equivariant measurable map from sprinklings to spacetime directions (even locally). Therefore, if a discrete structure is associated to a sprinkling in an intrinsic manner, then the structure will not pick out a preferred frame, locally or globally. This implies that the discreteness of a sprinkled causal set will not give rise to ``Lorentz breaking'' effects like modified dispersion relations. Another consequence is that there is no way to associate a finite-valency graph to a sprinkling consistently with Lorentz invariance.

Perturbations of circuit evolution matrices with Jordan blocks
Creators: name: Figotin, Alexander
Publisher: name: arXiv
Year: 2020
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: In our prior studies we synthesized special circuits possessing evolution matrices that involve nontrivial Jordan blocks and the corresponding degenerate eigenfrequencies. The degeneracy of this type is sometimes referred to as exceptional point of degeneracy (EPD). The simplest of these circuits are composed just of two LC-loops coupled by a gyrator and they are of our primary interest here. These simple circuits when near an EPD state can be used for enhanced sensitivity applications. With that in mind we develop here a comprehensive perturbation theory for these simple circuits near an EPD as well way to assure their stable operation. As to broader problem of numerical treatment of Jordan blocks and their perturbation we propose a few approaches allowing to detect the proximity to Jordan blocks.

description: In this study, we introduce a new approach to statistical decision theory. Without using a loss function, we select good decision rules to choice between two hypotheses. We call them "experts". They are globally unbiased but also conditionally unbiased on a family of events. We do not try to define the best expert. We define a probability distribution on the space of "experts". The measure of evidence for a hypothesis is the inductive probability of experts that decide this hypothesis, we call this measure: a "vote". We compare this point of view with the p-values. For some family of hypotheses, the "votes" can define a probability on the space of parameters. We compare these results with the Bayes posterior distributions. We study in detail real-parameter families of distributions with monotone likelihood ratio and multiparameter exponential families.

description: Motivated by the unsettled conclusion on whether there are any transit timing variations (TTVs) for the exoplanet Qatar-1b, 10 new transit light curves are presented and the TTV analysis with a baseline of 1400 epochs are performed. Because the linear model provides a good fitting with reduced chi-square = 2.59 and the false-alarm probabilities of possible TTV frequencies are as large as 35 %, our results are consistent with a null-TTV model. Nevertheless, a new ephemeris with the reference time T_0 = 2455647.63360\pm 0.00008 (BJD) and the period P= 1.4200236\pm 0.0000001 (day) is obtained. In addition, the updated orbital semi-major axis and planetary radius in unit of stellar radius are being provided, and the lower limit of modified stellar tidal quality factor is also determined.

The method can be successfully applied, as we demonstrate, to define new configurations when changes to the array take place. This may include the addition of new pads or new antennas, or the loss of pads or antennas. Our method is based on identifying which placement of elements provides the most appropriate uv plane sampling for astronomical imaging.

The multiple worlds of Murakami Haruki
Creators: name: Ambury, Brad
Publisher: name: University of British Columbia
Year: 2009

description: The focus of this thesis is Murakami's consistent textual evocations of a parallel world-within-a-world motif. By examining works in which these narrative constructs are most prominent, the analysis will delineate and clarify the structures and thematic significance of such constructs within his fictions and their function in the creation and,even, interpretation of Murakami's other realms. This thesis will also explore the possibilities of links, whether conscious or unconscious, between Murakami's fictions and a modern Japanese literary paradigm for which the term, Mukogawa ('the other-side') fiction, has been coined. It is hoped that the structural and thematic analyses outlined above might aid in the tracing of connections to a Japanese literary tradition with which, according to most critics, Murakami's fictions have nothing in common. By examining similar topoi and textual manifestations of difference, I hope that certain aspects of his fictions will better stand out. At the same time, recognizing the need to keep one eye open to recent critical studies, I will incorporate aspects of theoretical approaches to Magic Realism, a literary phenomenon not unlike mukogawa fiction, that might better enable my analysis of the recurring fantasylike parallel worlds of Murakami and shed more light on his relation to a literary tradition that developed out of the perceived sense of 'loss' (identity, culture, roots) that occurred during the rapid modernization of Japan from the Meiji period onwards.
Supersymmetric contribution to the CP asymmetry of B-> J/ψϕin the light of recent B_s -\bar{B}_s measurements

Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We derive new model independent constraints on the supersymmetric extensions of the standard model from the new experimental measurements of B_s -\bar{B}_s mass difference. We point out that supersymmetry can still give a significant contribution to the CP asymmetry of B_s ->J/ψϕthat can be measured at the LHCb experiment. These new constraints on the LL and RR squark mixing severely restricted their possible contributions to the CP asymmetries of B-> ϕK and B - >η' K. Therefore, SUSY models with dominant LR flavor mixing is the only way to accommodate the apparent deviation of CP asymmetries from those expected in the standard model. Finally we present an example of SUSY non-minimal flavor model that can accommodate the new ΔM_{B_s} results and also induces significant CP asymmetries in B_s ->J/ψϕ, B->ϕK and B ->η' K processes.

description: Group theoretic method for the systematic study of five-quark states with meson-baryon ($q\bar{q}-q^3$) configuration is developed. The calculation of matrix elements of many body Hamiltonian is simplified by transforming the physical bases (meson-baryon quark cluster bases) to symmetry bases (group chain classified bases), where the fractional parentage expansion method can be used. Three quark models, the naive Glashow-Isgur model, Salamanca chiral quark model and quark delocalization color screening model, are used to show the general applicability of the method and general results of constituent quark models for five-quark states are given. The method can also be useful in the calculation of meson-baryon scattering and the study of the five-quark components effect in baryon structure. The physical contents of different model configurations for the same multi-quark system can also be compared through the transformation between different physical bases to the same set of symmetry bases.

description: We study the encounters between stars clusters and giant molecular clouds (GMCs). The effect of these encounters has previously been studied analytically for two cases: 1) head-on encounters, for which the cluster moves through the centre of the GMC and 2) distant encounters, where the encounter distance p > 3*R_n, with p the encounter parameter and R_n the radius of the GMC. We introduce an expression for the energy gain of the cluster due to GMC encounters valid for all values of p and R_n. This analytical result is confronted with results from N-body simulations and excellent agreement is found. From the simulations we find that the fractional mass loss is only 25% of the fractional energy gain. This is because stars escape with velocities much higher than the escape velocity. Based on the mass loss, we derive a disruption time for star clusters due to encounters with GMCs of the form t_dis [Gyr] = 2.0*S*(M_c/10^4 M_sun)^gamma, with S=1 for the solar neighbourhood and inversely proportional with the global GMC density and gamma=1-3lambda, with lambda the index that relates the cluster half-mass radius to the cluster mass (r_h ~ M_c^lambda). The observed shallow relation between cluster radius and mass (e.g. lambda=0.1), makes the index (gamma=0.7) similar to the index found both from observations and from simulations of clusters dissolving in tidal fields (gamma=0.62). The constant of 2.0 Gyr, which is the disruption time of a 10^4 M_sun cluster in the solar neighbourhood, is close to the value of 1.3 Gyr which was empirically determined from the age distribution of open clusters. This suggests that the combined effect of GMC encounters, stellar evolution and galactic tidal field can explain the lack of old open clusters in the solar neighbourhood.

description: The expected possession value (EPV) of a soccer possession represents the likelihood of a team scoring or receiving the next goal at any time instance. By decomposing the EPV into a series of subcomponents that are estimated separately, we develop a comprehensive analysis framework providing soccer practitioners with the ability to evaluate the impact of both observed and potential actions. We show we can obtain calibrated models for all the components of EPV, including a set of yet-unexplored problems in soccer. We produce visually-interpretable probability surfaces for potential passes from a series of deep neural network architectures that learn from low-level spatiotemporal data. Additionally, we present a series of novel practical applications providing coaches with an enriched interpretation of specific game situations.

There is a noticeable difference in their appearance, ride, cost and performance. Since Kentucky utilizes both pavements, as many states do, it is necessary to have a system in place to consistently identify pavement distress and categorize their overall performance.

description: Spin relaxation in graphene is investigated in electrical graphene spin valve devices in the non-local geometry. Ferromagnetic electrodes with in-plane magnetizations inject spins parallel to the graphene layer. They are subject to Hanle spin precession under a magnetic field $B$ applied perpendicular to the graphene layer. Fields above 1.5 T force the magnetization direction of the ferromagnetic contacts to align to the field, allowing injection of spins perpendicular to the graphene plane. A comparison of the spin signals at B = 0 and B = 2 T shows a 20 % decrease in spin relaxation time for spins perpendicular to the graphene layer compared to spins parallel to the layer. We analyze the results in terms of the different strengths of the spin orbit effective fields in the in-plane and out-of-plane directions.

description: Model-based experimental design is attracting increasing attention in chemical process engineering. Typically, an iterative procedure is pursued: an approximate model is devised, prescribed experiments are then performed and the resulting data is exploited to refine the model. To help to reduce the cost of trial-and-error approaches, strategies for model-based design of experiments suggest experimental points where the expected gain in information for the model is the largest. It requires the resolution of a large nonlinear, generally nonconvex, optimization problem, whose solution may greatly depend on the starting point. We present two discretization strategies that can assist the experimenter in setting the number of relevant experiments and performing an optimal selection, and we compare them against two pattern-based strategies that are independent of the problem. The validity of the approaches is demonstrated on an academic example and two test problems from chemical engineering including a vapor liquid equilibrium and reaction kinetics.

description: Making data compliant with the FAIR Data principles (Findable, Accessible, Interoperable, Reusable) is still a challenge for many researchers, who are not sure which criteria should be met first and how. Illustrated from experimental data tables associated with a Design of Experiments, we propose an approach that can serve as a model for a research data management that allows researchers to disseminate their data by satisfying the main FAIR criteria without insurmountable efforts. More importantly, this approach aims to facilitate the FAIRification process by providing researchers with tools to improve their data management practices.

description: Possibilities of all-angle left-handed negative refraction in 2D honeycomb and Kagome lattices made of dielectric rods in air are discussed for the refractive indices 3.1 and 3.6. In contrast to triangular lattice photonic crystals made of rods in air, both the honeycomb and Kagome lattices show all-angle left-handed negative refraction in the case of the TM2 band for low normalized frequencies. Certain advantages of the honeycomb and Kagome structures over the triangular lattice are emphasized. This specially concerns the honeycomb lattice with its circle-like equifrequency contours where the effective indices are close to -1 for a wide range of incident angles and frequencies.

The repair, using externally bonded fiber system, offers the following benefits: (1) the use of light construction equipment, hand kits and tools, (2) minimal traffic disruption as all lanes were open to traffic while work was being performed underneath the bridge, and (3) cost saving; the cost for the repair and 3-years monitoring was USD $105,000.00 compared to the estimated superstructure replacement cost of USD $600,000.00. The repair began in June 2001 and was completed in October 2001. After the repair, crack gauges were used to monitor all shear cracks that existed in the bridge. Inspection of the bridge was carried out at specific intervals from October 2001 to July 2005. No crack movement has been observed during the inspections. This indicates that the retrofit was a success.

description: There has been greater emphasis in recent times on using public-private partnerships (PPPs or P3s) to provide and deliver transportation infrastructure and services. These public-private partnerships differ from contracting out, being applicable to a broader range of projects and requiring different contract management and accountability. In the transportation arena the focus on public-private partnerships has resulted from both the need for greater reliance on private capital to fund critical infrastructure and services and the need to tap private sector expertise to ensure delivery of high quality infrastructure and services on time and on budget. This report serves as a primer on public-private partnerships for the delivery of transportation infrastructure and services. It provides an overview of the concept of public-private partnerships, presenting a broad definition of the privatization approach, comparing it to contracting out, and discussing a theoretical framework for understanding why, when and how partnerships are appropriate as a privatization strategy. The report also reviews six public-private partnership models – design bid build, private contract fee services, design build, design build operate maintain or build operate transfer, design build finance operate, and build own operate – identified by the Federal Highway Administration as available for use by transportation agencies considering privatizing transportation projects. Adopting a public-private partnership involves two important decisions – (1) the decision to privatize via a public-private partnership; and (2) the decision on which partnership model to adopt – which are also addressed. This report also discusses key issues and factors necessary for successful transportation public-private partnerships and provides a glossary of terms as a reference for understanding the terminology and language of privatization and public-private partnerships.

description: Recent technological improvements in vehicle manufacturing may greatly improve safety however, the individuals' driving behaviour still remains a factor of paramount importance with aggressiveness, lack of focus and carelessness being the main cause of the majority of traffic incidents. The imminent deployment of 5G networking infrastructure, paired with the advent of Fog computing and the establishment of the Internet of Things (IoT) as a reliable and cost-effective service delivery framework may provide the means for the deployment of an accurate driving monitoring solution which could be utilized to further understand the underlying reasons of peculiar road behaviour, as well as its correlation to the driver's physiological state, the vehicle condition and certain environmental parameters. This paper presents some of the fundamental attributes of Fog computing along with the functional requirements of a driving behaviour monitoring framework, followed by its high level architecture blueprint and the description of the prototype implementation process.
Direct measurement of the absolute branching fraction for $D^+ \to {\bar K}^0μ^+ν_μ$ and determination of $ Γ(D^0 \to K^-μ^+ν_μ)/Γ(D^+ \to {\bar K}^0μ^+ν_μ)$

description: The absolute branching fraction for the decay $D^+ \to {\bar K}^0μ^+ν_μ$ is determined using $5321 \pm 149 \pm160$ singly tagged $D^-$ sample from the data collected around 3.773 GeV with the BESII detector at the BEPC collider. In the system recoiling against the singly tagged $D^-$ mesons, $28.7 \pm 6.4$ events for $D^+ \to {\bar K}^0μ^+ν_μ$ are observed. These yield the absolute branching fraction to be $BF(D^+ \to {\bar K}^0μ^+ν_μ) = (10.3\pm2.3\pm0.8)%$. The ratio of the two partial widths for the decays $D^0 \to K^-μ^+ν_μ$ and $D^+ \to {\bar K}^0μ^+ν_μ$ is determined to be $Γ(D^0 \to K^-μ^+ν_μ)/Γ(D^+ \to {\bar K}^0μ^+ν_μ) = 0.87 \pm 0.24 \pm 0.15$.

description: The session focuses on Krippendorff’s lifelong engagement with cybernetics, beginning with his exposure to ideas at Ulm through to his 1980s turn to second-order, social constructionist cybernetics. He revisits his graduate school encounters with Rosh Ashby, and his ongoing importance for his (Krippendorff’s) thought. His involvement in cybernetics-related conferences and scholarly societies, like the American Society for Cybernetics and the Society for General Systems Research, are recounted. Considerable attention is paid to Krippendorff’s organization of a 1974 Annenberg School of Communications conference, on Communication and Control in Social Processes, and the 1979 book that emerged from the conference. Krippendorff traces his constructionist turn to Margaret Mead’s paper at the 1967 Gaithersburg American Society for Cybernetics gathering, though he explains that his full engagement with what he called the cybernetics of cybernetics occurred in the early 1980s. His Annenberg teaching on cybernetics-related themes is discussed. Krippendorff describes the cybernetics implications for communication theory and ethics, through to publications appearing in the late 2000s.
Making KYTC Geotechnical Reports Available on the Web

description: The Geotechnical Branch of the Kentucky Transportation Cabinet (KYTC) prepares technical reports that contain drawings, explanations, and recommendations for road and structure construction projects in Kentucky. These design reports, once complete, also serve as historical reference materials for new projects and are utilized by State contractors, regional transportation offices, as well as the KYTC staff in Frankfort, KY. In order to reduce the support needed to distribute these documents to their constituents, the KYTC required a Web-based system for storing and disseminating the reports. The system developed under this project allows KYTC staff to upload an electronic document from any Web-accessible location and catalog the contents of the reports into a relational database. A map interface was developed to facilitate locating projects with varying kinds of geographic reference on a topographic base. Once entered into the system, reports can be identified and viewed using either a text-based or map-based search tool.  The data entry forms were developed as dynamic Web pages using Active Server Pages (ASP) scripting language. The document upload functionality is managed with a third party software product called AspUpload (© Persits Software, Inc.). The data entry program collects metadata about the operator for tracking, and catalogs information about the project’s geographic location, purpose, geologic context, and the nature of the included documents. Projects can be located by a number of methods, including county name, route name, road intersection, and milepoint identifiers, 7.5-minute quadrangle name, and place names. Minimum and maximum coordinate extents can be assigned using an interactive Web map, and these rectangular areas are managed in a database to permit viewing on the map. Drill hole coordinate lists can be uploaded, re-projected, and posted on the map as an alternative method of locating the extent of a project.  A Web-based search form was developed to allow users to find reports according to geographic and other descriptive characteristics of the projects. Over 4000 reports, approximately 70 percent of the library, are currently accessible from the system.

description: We analytically and numerically study the effects of pulsed control on the decoherence of a qubit coupled to a quantum spin bath. When the environment is critical, decoherence is faster and we show that the control is relatively more effective. Two coupling models are investigated, namely a qubit coupled to a bath via a single link and a spin star model, yielding results that are similar and consistent.

Subjects: subject: Transportation Engineering

description: The objective of this study was to develop a training course and handbook to guide on-scene emergency responders responsible for controlling traffic during a roadway crash and subsequent clearance.  Traffic control is an essential component of incident response in order to move road users safely and expeditiously past or around a traffic incident, and to reduce the likelihood of secondary crashes. Emergency responders, with the exception of law enforcement, are provided limited or no training in traffic control but yet by nature of their job often have to perform such duties. There is a need to provide basic knowledge and requirements to on-scene responders in order to reduce traffic delays, secondary crashes, and injuries to those involved in response activities.  Deliverables from the study efforts include workshop materials and a presentation suitable for use in training a wide range of incident responders. In addition, information from the presentation materials and the Manual on Uniform Traffic Control Devices has been excerpted and condensed into a handbook titled “Guidelines for Emergency Traffic Control”.
