description: This report documents the selection and sampling of 21 long-term pavement performance testing sites. Seven of those sites were also chosen to be a part of the LTPP portion of the Strategic Highway Research Program (SHRP). All sites were sampled in accordance with SHRP protocol and procedures.  The report includes three years of visual distress data and pavement deflection data obtained by a Road Rater. There were wide variabilities in backcalculated subgrade moduli and asphaltic concrete moduli within each 500-foot test section.  Laboratory resilient modulus tests were performed on undisturbed samples of the subgrade and asphaltic concrete cores. Again, there was wide variability between laboratory resilient moduli and backcalculated moduli from field deflection.  A number of models were developed to permit estimation of pavement distresses with time, AADT's, or ESAL's. In addition, relationships were developed between laboratory and field data.  It is recommended that longer-term data be obtained, to refine the models and to make their estimations more accurate. The models developed in this study can estimate the service history of a pavement.

A study of orbifolds
Creators: name: Milley, Peter Lawrence
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is a study of the theory of orbifolds and their applications in low-dimensional topology and knot theory. Orbifolds are a generalization of manifolds, and provide a larger, richer context for many of the concepts of manifold theory, such as covering spaces, fibre bundles, and geometric structures. Orbifolds are intimately connected with both the theory of Seifert fibrations and with knot theory, both of which are connected to the theory and classification of three-dimensional manifolds. Orbifolds also provide a new way to visualize group actions on manifolds, specifically actions which are not free. In chapter one we motivate the discussion with the history of orbifolds, and then we define orbifolds and certain key related terms. We extend the theory of orbifolds in chapter two to encompass many of the concepts of manifold theory, such as fibre bundles, covering spaces, and orbifold geometry. We also see in chapter two the proof that every orbifold with a geometric structure is covered by a manifold, a result which does not have an analogue in manifold theory. In chapter three we study and classify compact two-dimensional orbifolds, and show how to construct hyperbolic geometric structures for a vast majority of such orbifolds. We examine the connections between orbifolds and Seifert fibrations in chapter four. We pass on to three dimensions in chapter five. In that chapter we not only study the local structure of three-dimensional orbifolds, we also study polyhedral orbifolds and examine the consequences of Andreev's theorem. We also look at ways of constructing orbifolds from Dehn surgery diagrams in chapter five. Finally in chapter six we discuss more advanced topics, such as the state of the Geometrization Theorem for orbifolds, as well as orbifold differential geometry and orbifold topological invariants including extensions of the fundamental group and the homology groups.

Enhancements of the 3/2 and 5/2 frequencies of de Haas-van Alphen oscillations near the Lifshitz transition in the two-dimensional compensated metal with overtilted Dirac cones

description: We study the de Haas-van Alphen (dHvA) oscillations in the two-dimensional compensated metal with overtilted Dirac cones near the Lifshitz transition. We employ the tight-binding model of $α$-(BEDT-TTF)$_2$I$_3$, in which the massless Dirac fermions are realized. When a uniaxial pressure $(P)$ along the $y$-axis is applied above $P\simeq 0.2$ kbar in $α$-(BEDT-TTF)$_2$I$_3$, one electron pocket, which encloses the overtilted Dirac points, is changed to two electron pockets, i.e., Lifshitz transition happens, while a hole pocket does not change a topology. We show that the Fourier components corresponding to the $3/2$ and $5/2$ areas of the hole pocket are anomalously enhanced in the region of pressure where the Lifshitz transition occurs. This phenomenon will be observed in the two-dimensional overtilted Dirac fermions near the Lifshitz transition.

Higher-order effects in the dynamics of hierarchical triple systems. Quadrupole-squared terms

description: We analyze the secular evolution of hierarchical triple systems to second-order in the quadrupolar perturbation induced on the inner binary by the distant third body. The Newtonian three-body equations of motion, expanded in powers of the ratio of semimajor axes $a/A$, become a pair of effective one-body Keplerian equations of motion, perturbed by a sequence of multipolar perturbations, denoted quadrupole, $O[(a/A)^3]$, octupole, $O[(a/A)^4]$, and so on. In the Lagrange planetary equations for the evolution of the instantaneous orbital elements, second-order effects arise from obtaining the first-order solution for each element, consisting of a constant (or slowly varying) piece and an oscillatory perturbative piece, and reinserting it back into the equations to obtain a second-order solution. After an average over the two orbital timescales to obtain long-term evolutions, these second-order quadrupole ($Q^2$) terms would be expected to produce effects of order $(a/A)^6$. However we find that the orbital average actually enhances the second-order terms by a factor of the ratio of the outer to the inner orbital periods, $ \sim (A/a)^{3/2}$. For systems with a low-mass third body, the $Q^2$ effects are small, but for systems with a comparable-mass or very massive third body, such as a Sun-Jupiter system orbiting a solar-mass star, or a $100 \, M_\odot$ binary system orbiting a $10^6 \, M_\odot$ massive black hole, the $Q^2$ effects can completely suppress flips of the inner orbit from prograde to retrograde and back that occur in the first-order solutions. These results are in complete agreement with those of Luo, Katz and Dong, derived using a "Corrected Double-Averaging" method.

description: Point defects are ubiquitous in two dimensional crystals and play a fundamental role in determining their mechanical and thermodynamical properties. When crystals are formed on a curved background, finite length grain boundaries (scars) are generally needed to stabilize the crystal. We provide a continuum elasticity analysis of defect dynamics in curved crystals. By exploiting the fact that any point defect can be obtained as an appropriate combination of disclinations, we provide an analytical determination of the elastic spring constants of dislocations within scars and compare them with existing experimental measurements from optical microscopy. We further show that vacancies and interstitials, which are stable defects in flat crystals, are generally unstable in curved geometries. This observation explains why vacancies or interstitials are never found in equilibrium spherical crystals. We finish with some further implications for experiments and future theoretical work.

Federated Learning at the Network Edge: When Not All Nodes are Created Equal

Year: 2021
Subjects: subject: Networking and Internet Architecture (cs.NI)

description: Under the federated learning paradigm, a set of nodes can cooperatively train a machine learning model with the help of a centralized server. Such a server is also tasked with assigning a weight to the information received from each node, and often also to drop too-slow nodes from the learning process. Both decisions have major impact on the resulting learning performance, and can interfere with each other in counterintuitive ways. In this paper, we focus on edge networking scenarios and investigate existing and novel approaches to such model-weighting and node-dropping decisions. Leveraging a set of real-world experiments, we find that popular, straightforward decision-making approaches may yield poor performance, and that considering the quality of data in addition to its quantity can substantially improve learning.

description: All metal objects support fluctuating currents that are responsible for evanescent-wave Johnson noise in their vicinity due both to thermal and quantum effects. The noise fields can decohere qubits in their neighborhood. It is quantified by the average value of $B(x,t)B(x',t')$ and its time Fourier transform. We develop the formalism particularly for objects whose dimensions are small compared with the skin depth, which is the appropriate regime for nanoscale devices. This leads to a general and surprisingly simple formula for the noise correlation function of an object of arbitrary shape. This formula has a clear physical interpretation in terms of induced currents in the object. It can also be the basis for straightforward numerical evaluation. For a sphere, a solution is given in closed form in terms of a generalized multipole expansion. Plots of the solution illustrate the physical principles involved. We give examples of how the spatial pattern of noise can affect quantum information processing in nearby qubits. The theory implies that if the qubit system is miniaturized to a scale $D$, then decoherence rates of qubits scale as $1/D$.

description: The objectives of the current cost allocation study, the fifth in a series begun in 1982, include the following: 1) to evaluate current cost allocation methodologies and identify possible changes to Kentucky practices; and 2) to determine the 1991 fiscal year levels of cost responsibility and revenue contribution for each of several classes of highway users. Additional objectives include an evaluation of the equity of tax proposals advanced by the Kentucky Motor Transport Association, a preliminary determination of the revenue and cost implications of the Extended-Weight Coal Haul System, and an evaluation of the efficiency with which certain highway user taxes have been collected.  As was the case in other recent cost-allocation studies, incremental cost assignment has been replaced with various highway use measures including vehicle-miles of travel, axle-miles, passenger-car-equivalent miles, and equivalent-single-axle-load miles.  Results from the analysis indicate that cost responsibility was borne most heavily by passenger cars and motorcycles (44.2 percent). Other cost responsibilities were 24.6 percent for heavy trucks; 20.4 percent for pickups and vans; and 10.8 for all other groups. When compared to revenue for each vehicle class; cars, pickups and vans, and heavy trucks exceeded their cost responsibility, while medium trucks fell significantly short. From a limited examination of the Extended-Weight Coal Haul System, it was found that an estimated $2 million are lost annually from the Road Fund because fewer trucks are registered. Heavier weights of coal-decal trucks add approximately $9 million annually to pavement overlay costs. Related to tax collection, it was found that the weight-distance tax was collected at an efficiency of about 70 percent and other user-reported fuel taxes in the range of 75 to 77 percent.

description: We propose a new class of Bayesian neural networks (BNNs) that can be trained using noisy data of variable fidelity, and we apply them to learn function approximations as well as to solve inverse problems based on partial differential equations (PDEs). These multi-fidelity BNNs consist of three neural networks: The first is a fully connected neural network, which is trained following the maximum a posteriori probability (MAP) method to fit the low-fidelity data; the second is a Bayesian neural network employed to capture the cross-correlation with uncertainty quantification between the low- and high-fidelity data; and the last one is the physics-informed neural network, which encodes the physical laws described by PDEs. For the training of the last two neural networks, we use the Hamiltonian Monte Carlo method to estimate accurately the posterior distributions for the corresponding hyperparameters. We demonstrate the accuracy of the present method using synthetic data as well as real measurements. Specifically, we first approximate a one- and four-dimensional function, and then infer the reaction rates in one- and two-dimensional diffusion-reaction systems. Moreover, we infer the sea surface temperature (SST) in the Massachusetts and Cape Cod Bays using satellite images and in-situ measurements. Taken together, our results demonstrate that the present method can capture both linear and nonlinear correlation between the low- and high-fideilty data adaptively, identify unknown parameters in PDEs, and quantify uncertainties in predictions, given a few scattered noisy high-fidelity data. Finally, we demonstrate that we can effectively and efficiently reduce the uncertainties and hence enhance the prediction accuracy with an active learning approach, using as examples a specific one-dimensional function approximation and an inverse PDE problem.

Detecting the Glint of Starlight on the Oceans of Distant Planets

description: We propose that astronomers will be eventually be able to discriminate between extrasolar Earth-like planets with surface oceans and those without using the shape of phase light curves in the visible and near-IR spectrum. We model the visible light curves of planets having Earth-like surfaces, seasons, and optically-thin atmospheres with idealized diffuse-scattering clouds. We show that planets partially covered by water will appear measurably brighter near crescent phase (relative to Lambertian planets) because of the efficient specular reflection (i.e., glint) of starlight incident on their surfaces at a highly oblique angle. Planets on orbits within 30 degrees of edge-on orientation (half of all planets) will show pronounced glint over a sizeable range of orbital longitudes, from quadrature to crescent, all outside the glare of their parent stars. Also, water-covered planets will appear darker than a Lambertian disk near full illumination. Finally, we show that planets with a mixed land/water surface will polarize the reflected signal by as much as 30-70 percent. These results suggest several new ways of directly identifying water on distant planets.

description: The purpose of this study was to carry out an investigation on the role of supply chain collaboration oncustomer satisfaction among manufacturing firms in Kenya. Studies by previous researchers haveindicated that manufacturingfirms faces the challenges of uncertainty associated with sourcing for rawmaterials from oversees and failure to embrace modern technology which adversely affected the ability tosatisfy customers. The general objective of the study was to determine the role of supply chaincollaboration on customer satisfaction among manufacturing firms in Kenya. Specific objectives was: Toestablish the roleof supply chain collaboration on customer satisfaction among manufacturing firms inKentaThe target population was flour milling firms in Kenya. The study used the simple random samplingtechnique will be used to select the sample size. There were 800 employees involved directly andindirectly in the supply chain process in this sector. The sample was 30% of the employees and this willresult to a sample size of 240 employees. The study used questionnaires to gather data. Descriptiveanalysis was used to analyze the data which was presented in the form of frequencies, tables andpercentages.The results of the study indicated that supply chain collaboration was instrumental in ensuringresponsiveness in the entire supply chain. The study concluded that there is an urgent need fororganizations to adopt pro-active approach towards customer satisfaction by adopting practices thatprovide real-time and accurate response to customer satisfaction. The role played by supply chaincollaboration is critical in achieving sustainable customer satisfaction. This study recommends thatmanufacturing firms should leverage on supply chain best practices particularly supply chain collaborationas a big differentiator in providing customer satisfaction and value by eliminating the barricades betweencustomers and suppliers.The study also made suggestions for further research to be undertaken on the role of supply chain bestpractices in service delivery in the public sector.

description: Since 2009, OpenAIRE has been serving research communities around Europe by facilitating the compliance to the EC’s mandates on Open Access and Open Science. With more than 30 mi publications (and 1,5 mi research data and 100k software) available through its portal and APIs, OpenAIRE is an essential resource in the Open Science landscape providing access and research sharing and building advanced services on top of the data collected in the OpenAIRE infrastructure. Our current efforts are focused on re-designing and enhancing OpenAIRE’ services via a set of dashboards. Each of them is serving specific stakeholders (Content Providers, Research Communities, Research Funders, and Institutions) and is aiming to include Open Science in research and research administration workflows. These services provide a rich set of open scholarly outputs, from publications, that also encompasses grey literature, to research organizations and project information. The OpenAIRE service infrastructure harvests metadata about scholarly communication products (literature, datasets, software, and other research products) and links between such products from a range of institutional or subject repositories, national and institutional research information portals, aggregators, e-journals, data repositories, and software repositories. In addition, it infers links between literature and such products via advanced text and data mining techniques. The resulting information graph is intended to favor monitoring of open science (e.g. science reproducibility and transparent research assessment). OpenAIRE is one of the key pillars in the European Open Science Cloud (EOSC), representing the “O” in this context. In fact, through the network of National Open Access Desks all over the European countries. OpenAIRE contributes to the implementation and alignment of policies and guidelines on and for Open Science in Europe and beyond. Through this, OpenAIRE connects Open Science in Europe and around the world. Means of shaping Open Science in the framework of the EOSC also pass through the training activities OpenAIRE organises periodically on various topics, from the basics about the compliance to EC’s mandates on Open Access and Open Science to those on Data Management and related legal issues to the technical ones on how to become an OpenAIRE content provider and use the available services.

description: Miniaturization of devices has been a primary objective in microelectronics and photonics for decades, aiming at denser integration, enhanced functionalities and drastic reduction of power consumption. Headway in nanophotonics is currently linked to the progress in concepts and technologies necessary for applications in information and communication, brain inspired computing, medicine and sensing and quantum information. Amongst all nanostructures, semiconductor photonic crystals (PhCs) occupy a prominent position as they enable the fabrication of quasi ultimate optical cavities. Low threshold laser diodes or Raman lasers , low power consuming optical memories , efficient single photon sources or single photon quantum gates are impressive examples of their capabilities. We report the demonstration of about 20 micron long PhC semiconductor optical parametric oscillator (OPO) at telecom wavelength exploiting nearly diffraction limited optical modes. The pump power threshold is measured below 0.2 mW. Parametric oscillation was reached through the drastic enhancement of Kerr optical Four Wave Mixing by thermally tuning the high Q modes of a nanocavity into a triply resonant configuration. Miniaturization of this paradigmatic source of coherent light paves the way for quantum optical circuits, dense integration of highly efficient nonlinear sources of squeezed light or entangled photons pairs.

description: Στην εργασία αυτή πραγματοποιήθηκε επιτυχώς α. η απομόνωση του cdna της ανθρώπινης β-σφαιρίνης από υγιή εθελοντή β. η κλωνοποίηση του cdna της β-σφαιρνίνης, εφαρμόζοντας την τεχνολογία της πρωτεϊνικής μεταγωγής, στο βακτηριακό φορέα έκφρασης ptyb11, με εισαγωγή τόσο της αλληλουχίας tat-ha, όσο και της θέσης κοπής από τον παράγοντα xa για τον καθαρισμό της πρωτεϊνης. Επαγωγή της έκφρασης οδήγησε στην παραγωγή της πρωτεϊνης σύντηξης ιντεϊνης-βσφαιρίνης-tat-ha και της πρωτεϊνης σύντηξης ιντεϊνης-xasite-βσφαιρίνης tat-ha. Ο καθαρισμός και η απομόνωση της β-σφαιρίνης tat ha θα βοηθήσουν στη διεξαφωγή πειραμάτων ενδοκυτταρικής μεταφοράς της πρωτεςΐνης σε ερυθρολευχαιμικά Κ562 κύτταρα. Τα πειράματα αυτά θα πραγματοποιηθούν για την αξιολόγηση της μεταφοράς, της ανασυγκρότησης και της λειτουργικότητας της αιμοσφαιρίνηςHba και θα είναι ενδεικτική για την πιθανότητα μεταφοράς της πρωτεΐνης σε πρόδρομα κύτταρα της ερυθράς σειράς ως εναλλακτική θεραπευτική προσέγγιση των βο-θαλασσαιμικών ασθενών
description: In this project we managed to do : 1. isolation of the Cdna of b-hemoglobin from human healthy blood sample 2. cloning of the Cdna by using the technology of protein transduction domain, in the expression vector ptvbii by using the tat-ha domain and the xa site for the purification of the protein. Induction of the produced clones led ta the expression of the fused intein-b-globin tat-ha protein and intein -xasite-b-globin tat-ha protein. The purification of b-globin-tat-ha protein will help to proceed in the transduction of the protein to k562 erythroleukemia cells. These experiments will be useful for the examination of the transduction and the restoration of the basic domain and function of HbA. Finally the results will be useful for the possibility of the transduction of the protein into reticulocytes derived from b-thalassemic patients, as an alternative therapeutic approach

description: Stochastic inflation describes the global structure of the inflationary universe by modeling the super-Hubble dynamics as a system of matter fields coupled to gravity where the sub-Hubble field fluctuations induce a stochastic force into the equations of motion. The super-Hubble dynamics are ultralocal, allowing us to neglect spatial derivatives and treat each Hubble patch as a separate universe. This provides a natural framework in which to discuss probabilities on the space of solutions and initial conditions. In this article we derive an evolution equation for this probability for an arbitrary class of matter systems, including DBI and k-inflationary models, and discover equilibrium solutions that satisfy detailed balance. Our results are more general than those derived assuming slow roll or a quasi-de Sitter geometry, and so are directly applicable to models that do not satisfy the usual slow roll conditions. We discuss in general terms the conditions for eternal inflation to set in, and we give explicit numerical solutions of highly stochastic, quasi-stationary trajectories in the relativistic DBI regime. Finally, we show that the probability for stochastic/thermal tunneling can be significantly enhanced relative to the Hawking-Moss instanton result due to relativistic DBI effects.

description: A sound wave travelling in water is scattered by a periodic assembly of air bubbles. The local structure matters even in the low frequency regime. If the bubbles are arranged in a face-centered cubic (fcc) lattice, a total band gap opens near the Minnaert resonance frequency. If they are arranged in the diamond structure, which one obtains by simply adding a second bubble to the unit cell, one finds an additional branch with a negative slope (optical branch). For a single specific frequency, the medium behaves as if its refractive index (relative to water) is exactly $n=-1$. We show that a slab of this material can be used to design a three three-dimensional flat lens. We also report super-resolution focusing in the near field of the slab and illustrate its potential for imaging in three dimensions.

description: GST or Goods and Services Tax, the best tax reform in India since independence which has been long pending. GST is supposed to simplify the taxation regime of India by replacing a number of taxes by one unified tax. GST is that the only revenue enhancement that directly connects all the world of Indian economy thus enhancing the economic process of the country by creating one unified market. Over 160 countries of the planet have implemented GST up to now follow by France. The thought of GST in India was proposed by Atal Bihari Vajpayee in 1999 and a committee was founded under the leadership of Asim Das Gupta the then minister of finance of state. It had been purported to be implemented from 1 st April 2010 under flagship of P Chidambaram the then government minister of UPA government but because of political issues and conflicting interests of assorted stakeholders

description: A procedure to characterize chaotic dynamical systems with concepts of complex networks is pursued, in which a dynamical system is mapped onto a network. The nodes represent the regions of space visited by the system, while edges represent the transitions between these regions. Parameters used to quantify the properties of complex networks, including those related to higher order neighborhoods, are used in the analysis. The methodology is tested for the logistic map, focusing the onset of chaos and chaotic regimes. It is found that the corresponding networks show distinct features, which are associated to the particular type of dynamics that have generated them.

Subjects: subject: Transportation Engineering

description: In this study a procedure has been developed to evaluate the structural condition of pavements using Road Rater deflection measurements. These procedures compare actual field deflections with deflections calculated by the Chevron N-Layer linear elastic computer program. The results obtained from these procedures are the layer moduli of the pavement materials. Procedures have been developed for asphaltic concrete pavements and composite pavements, including broken and non-broken concrete layers. This report also contains a comparison of structural overlay determined using the results of the new procedure, with overlays calculated using results from the 2-3 Projected procedure currently used by the Pavement Management branch of the Kentucky Transportation Cabinet. A users manual from the computer programs developed during this study is included in the appendix of the report.

description: We compute numerically the sequence of successive pinned configurations of an elastic line pulled quasi-statically by a spring in a random bond (RB) and random field (RF) potential. Measuring the fluctuations of the center of mass of the line allows to obtain the functional renormalization group (FRG) functions at the depinning transition. The universal form of the second cumulant Delta(u) is found to have a linear cusp at the origin, to be identical for RB and RF, different from the statics, and in good agreement with 2-loop FRG. The cusp is due to avalanches, which we visualize. Avalanches also produce a cusp in the third cumulant, whose universal form is obtained, as predicted by FRG.

description: Motivated by a puzzle in the study of two dimensional lattice Quantum Electrodynamics with staggered fermions, we construct a two dimensional fermionic model with a global U(1) symmetry. Our model can be mapped into a model of closed packed dimers and plaquettes. Although the model has the same symmetries as the XY model, we show numerically that the model lacks the well known Kosterlitz-Thouless phase transition. The model is always in the gapless phase showing the absence of a phase with vortex condensation. In other words the low energy physics is described by a non-compact U(1) field theory. We show that by introducing an even number of layers one can introduce vortex condensation within the model and thus also induce a KT transition.
