description: The phase diagram of QCD at finite temperature and density and the existence of a critical point are currently very actively researched topics. Although tremendous progress has been made, in the case of two light quark flavors even the order of the phase transition at zero density is still under discussion. Finite-size scaling is a powerful method for the analysis of phase transitions in lattice QCD simulations. From the scaling behavior, critical exponents can be tested and the order as well as the universality class of a phase transition can be established. This requires knowledge of the critical exponents and the scaling behavior. We use a non-perturbative Renormalization Group method to obtain critical exponents and the finite-size scaling functions for the O(4) universality class in three dimensions. These results are useful for a comparison to the actual scaling behavior in lattice QCD simulations with two flavors, as well as for an estimate of the size of the scaling region and the deviations from the expected scaling behavior.

description: In a recent publication (Bertulani et al., PLB 650 (2007) 233 and arXiv:0704.0060v2) the validity of analysis methods used for intermediate-energy Coulomb excitation experiments was called into question. Applying a refined theory large corrections of results in the literature seemed needed. We show that this is not the case and that the large deviations observed are due to the use of the wrong experimental parameters. We furthermore show that an approximate expression derived by Bertulani et al. is in fact equivalent to the theory of Winther and Alder (NPA 319 (1979) 518), an analysis method often used in the literature.

description: Tainacan was born from the need of open technologies that could, with a low cost, address the interoperability and participation demands of cultural heritage institutions (museums, archives, libraries, galleries - GLAM) in the digital culture era. Starting from the vision that cultural engagement on the Internet is essentially a digital publishing operation, Tainacan takes advantage of WordPress' code and community to bring mature user interfaces and advanced publishing/presentation/participation features to the digital collections of the GLAM world. Tainacan is an effort to make it easier for these professionals to create, manage and spread their repositories with little dependence on IT technical skills. We design it in an effort to shorten the gap between the work of the end user and all the technical requisites of digital publishing. In other words, manage their repository, make it accessible in the web, discoverable by aggregators, sharable in social network and available in Linked Open Data RDF format. The presentation will cover a brief history of the project and its motivation, a live demonstration of the key features, highlighting the reasons to choose WordPress and it's integration with Elastic Search, interoperability and linked open data features.

description: Percutaneous devices are necessary tools in modern healthcare. More than one hundred fifty million percutaneous catheters have been purchased annually for various medical procedures, such as blood monitoring, urine drainage, and drug administration. However, catheter-related bloodstream infections occur in a high rate, up to 250,000 cases each year, and lead up to 25% mortality rate. One of the key causes is the skindevice incompatibility. It contributes to chronic inflammation and skin migration that generates a deep gap around the device. The lack of body outer barrier in such small area is ample for bacteria that accumulate near the insertion site to penetrate into the blood system, leading to a high risk of infections. Engineering of physical, chemical, and mechanical properties of percutaneous biomaterials is promising to improve host responses and ultimately prevent the infections. In this study, we design percutaneous biomaterials using three main approaches, i.e. surface topography, macrophage modulation, and protein-adsorption resisting materials, to attenuate the dermal downgrowth. The material in each design is characterized in in vitro environments to obtain physical, chemical, and mechanical properties, and also in in vivo milieu using a mouse model to profoundly investigate host responses. This work provides an insight of promising percutaneous material designs that reduce catheter-related complications and infections.

description: Modern mobile devices incorporate several transmit and receive antennas in highly constrained volumes. As miniaturized antennas impinge upon fundamental physical limits on efficiency, new design approaches are required to support ever-smaller devices with more varied and robust communication performance. We take an unconventional design approach in which an arbitrary metallic structure and its components can be modified to act as efficient radiators. Using eigenmode analysis and the theory of characteristic modes (TCM), we develop algorithms that allow for effective integration of antennas with mechanical structures and enable structure reuse, helping meet stringent space and weight constraints without sacrificing electromagnetic performance. We derive TCM-based objectives for effective exploration of the design space in the electromagnetic (EM) domain. The procedure includes a feed placement technique that identifies viable excitation points on the structure without running full EM analysis. In addition to computational advantages, this provides a point of comparison among a variety of antenna shapes. Empirical evaluation shows that the estimates of radiated power from TCM can effectively guide optimization toward structures with improved radiating properties. Automated feed placement increases the proportion of good-quality designs among the explored candidates by consistently selecting the most promising feed positions. The ability of the TCM-based algorithm to direct the search is further validated on two real-world applications: integration of a GPS antenna with the frame of a mobile phone and integration of an S-band antenna with the frame of a small spacecraft. To the best of our knowledge, this is the first work that applies TCM to automated optimization of antennas. We investigate how to leverage domain-specific methods and solution representations in the coupled optimization of antennas. We develop a novel multiobjective optimization framework based on local search in each domain. In this procedure, the local optima in each objective are obtained and modified to create a new population of candidate designs. On a number of benchmark problems, the proposed technique is competitive with leading multi-objective algorithms: while it finds a less uniform distribution along the Pareto front, it shows better performance in locating solutions at the boundaries of the tradeoff curve. The local search algorithm is successfully applied to topology optimization of an antenna for a CubeSat, a small low-cost satellite platform.

Perturbative QCD corrections to the production cross section for gluon fusion are calculated as well as the contributions from gluon-quark and quark-antiquark collisions to the total cross section. The dependence on the renormalization and factorization scales and on the choice of the parton distribution functions is explored. QCD corrections to the branching ratio of $η_{t}$ into $γγ$ are included and the two-loop QCD potential is used to predict the wave function at the origin. The branching ratio of $η_{t}$ into $γZ$, $ZZ$, $HZ$ and $WW$ is compared with the $γγ$ channel.

Publisher: name: arXiv
Year: 2018
Subjects: subject: Robotics (cs.RO)

description: In this paper, we introduce iBoW-LCD, a novel appearance-based loop closure detection method. The presented approach makes use of an incremental Bag-of-Words (BoW) scheme based on binary descriptors to retrieve previously seen similar images, avoiding any vocabulary training stage usually required by classic BoW models. In addition, to detect loop closures, iBoW-LCD builds on the concept of dynamic islands, a simple but effective mechanism to group similar images close in time, which reduces the computational times typically associated to Bayesian frameworks. Our approach is validated using several indoor and outdoor public datasets, taken under different environmental conditions, achieving a high accuracy and outperforming other state-of-the-art solutions.

description: Equilibrium configurations of electrically charged perfect fluid surrounding a central rotating black hole endowed with a test electric charge and embedded in a large-scale asymptotically uniform magnetic field are presented. Following our previous studies considering the central black hole non-rotating, we show that in the rotating case, conditions for the configurations existence change according to the spin of the black hole. We focus our attention on the charged fluid in rigid rotation which can form toroidal configurations centered in the equatorial plane or the ones hovering above the black hole, along the symmetry axis. We conclude that a non-zero value of spin changes the existence conditions and the morphology of the solutions significantly. In the case of fast rotation, the morphology of the structures is close to an oblate shape.

description: In this paper, we derive generalized Bern-Carrasco-Johansson relations for color-ordered Yang-Mills amplitudes by imposing gauge invariance conditions and dimensional reduction appropriately on the new discovered graphic expansion of Einstein-Yang-Mills amplitudes. These relations are also satisfied by color-ordered amplitudes in other theories such as color-scalar theory, bi-scalar theory and nonlinear sigma model (NLSM). As an application of the gauge invariance induced relations, we further prove that the three types of BCJ numerators in NLSM , which are derived from Feynman rules, Abelian Z-theory and Cachazo-He- Yuan formula respectively, produce the same total amplitudes. In other words, the three distinct approaches to NLSM amplitudes are equivalent to each other.

description: Quantum simulation on emerging quantum hardware is a topic of intense interest. While many studies focus on computing ground state properties or simulating unitary dynamics of closed systems, open quantum systems are an interesting target of study owing to their ubiquity and rich physical behavior. However, their non-unitary dynamics are also not natural to simulate on digital quantum devices. Here, we report algorithms for the digital quantum simulation of the dynamics of open quantum systems governed by a Lindblad equation using adaptations of the quantum imaginary time evolution (QITE) algorithm. We demonstrate the algorithms on IBM Quantum's hardware with simulations of the spontaneous emission of a two level system and the dissipative transverse field Ising model. Our work advances efforts to simulate the dynamics of open quantum systems on quantum hardware.

description: Complex systems are designed using the model-based design paradigm in which mathematical models of systems are created and checked against specifications. Cyber-physical systems (CPS) are complex systems in which the physical environment is sensed and controlled by computational or cyber elements possibly distributed over communication networks. Various aspects of CPS design such as physical dynamics, software, control, and communication networking must interoperate correctly for correct functioning of the systems. Modeling formalisms, analysis techniques and tools for designing these different aspects have evolved independently, and remain dissimilar and disparate. There is no unifying formalism in which one can model all these aspects equally well. Therefore, model-based design of CPS must make use of a collection of models in several different formalisms and use respective analysis methods and tools together to ensure correct system design. To enable doing this in a formal manner, this thesis develops a framework for multi-model verification of cyber-physical systems based on behavioral semantics. Heterogeneity arising from the different interacting aspects of CPS design must be addressed in order to enable system-level verification. In current practice, there is no principled approach that deals with this modeling heterogeneity within a formal framework. We develop behavioral semantics to address heterogeneity in a general yet formal manner. Our framework makes no assumptions about the specifics of any particular formalism, therefore it readily supports various formalisms, techniques and tools. Models can be analyzed independently in isolation, supporting separation of concerns. Mappings across heterogeneous semantic domains enable associations between analysis results. Interdependencies across different models and specifications can be formally represented as constraints over parameters and verification can be carried out in a semantically consistent manner. Composition of analysis results is supported both hierarchically across different levels of abstraction and structurally into interacting component models at a given level of abstraction. The theoretical concepts developed in the thesis are illustrated using a case study on the hierarchical heterogeneous verification of an automotive intersection collision avoidance system.

GLAM collaboration

description: In 2017, the University of Notre Dame received a grant from the Andrew W. Mellon Foundation to build a platform for digitized collections from the campus art museum and library. Although we know that users seek materials from the museum, rare books and special collections department, and university archives in tandem, these units are administratively distinct with collections that are held and accessed separately. Furthermore, available software solutions rarely accommodate collaboration between library and museum collections. A portal where museum and library sources are accessible in one place is therefore, a new undertaking for the University and for the field at large. How do you assess user needs for a brand new, innovative project? The grant funded a unique position, an Outreach Specialist, to ensure that development work on the project took a user-centered design approach. This person was tasked with gathering and assessing user needs as well as communicating with stakeholders about project milestones. This presentation will explore the benefits of creating a position devoted to understanding users in the GLAM context (gallery, library, archive, museum), the strategies used to assess user needs for a new and formerly non-existent platform, and the findings of the project's discovery and testing phase.

description: The survey focused on structural change towards inclusive gender equality in R&I organisations in the country. Structural change is defined here as a long-term, sustainable process, aimed at building an institutional environment (values, norms, structures and procedures) in which inclusive gender equality is widely discussed and explicitly embraced through organisational and individuals' practices that have a demonstrable impact on reducing gender and other axes of inequality and discrimination within the organisation.
The survey addressed five topics of interest related to structural change:

Initiating change: How organisations can be encouraged to adopt a gender equality policy (GEPs and equivalent/alternative measures) based on local knowledge, experience and change movements as well as evidence-based tools (e.g., gender equality audit).
Sustaining and deepening change: How organisations can address resistances and sustain and deepen change by building institutional gender competence, dedicating resources and structures, promoting evidence-based measures, and broadening the scope of intervention (e.g., integrating sex/gender analysis in curricula or research content; implementing a sexual harassment protocol).
Adopting an intersectional approach: How organisations can move from GEPs and/or EDI interventions to inclusive intersectional GEPs fostering change towards equality.
Implementing gendered innovations: How innovation clusters and private R&I companies can be encouraged to implement gendered innovations - that is to innovate by integrating methods of sex and gender analysis into their R&I products or services, ideally taking into account also other axes of inequality and discrimination.
Monitoring inclusive gender equality: How organisations can support an evidence-based inclusive gender equality by implementing effective monitoring conceptual approaches, tools, and indicators - in particular in the four topics identified above (initiating change; sustaining and deepening change; adopting an intersectional approach; implementing gendered innovations).

description: Unsegmented, large-volume liquid scintillator (LS) neutrino detectors have proven to be a key technology for low-energy neutrino physics. The efficient rejection of radionuclide background induced by cosmic muon interactions is of paramount importance for their success in high-precision MeV neutrino measurements. We present a novel technique to reconstruct GeV particle tracks in LS, whose main property, the resolution of topological features and changes in the differential energy loss $\mathrm{d}E/\mathrm{d}x$, allows for improved rejection strategies. Different to common track reconstruction approaches, our method does not rely on concrete track / topology hypotheses. Instead, based on a reference point in space and time, the observed distribution of photon arrival times at the photosensors and the detector's characteristics in terms of photon production, propagation and detection (optical model), it reconstructs the voxelized distribution of optical photon emissions. Techniques from three-dimensional data analysis can then be applied to extract parameters describing the topology, e.g., the direction of a track. We performed a first performance evaluation of our method using single muon events with up to $10\,\mathrm{GeV}$ from a Geant4 simulation of the LENA detector. The current results indicate that our approach is competitive with existing reconstruction methods -- although its full potential has not yet been exploited. We also remark on other detector technologies in astroparticle physics as well as applications in medical imaging that could benefit from the fundamental ideas of our method.

description: The main performance objective in an electric power grid entails timely and efficient generation and delivery to the time-varying electricity demand. As the electricity industry is witnessing proliferation of the mainstream renewables, the minute-by-minute variations in wind and solar power generation may result in temporary electricity scarcity that jeopardizes grid stability and quality of service. The evolving electricity markets are aimed at incentivizing the conventional generators to reinforce their operating flexibility. This dissertation concerns the goal of enhancing the dynamic response rates of interconnected controllable resources by means of a multi-layered fuel input control of electrically coupled heterogeneous energy conversion components. Both power engineering and large-scale control contributions are made in support of this enhancement. First, improved fuel input controls are designed to enable flexible physics-based energy conversion dynamics required by the interconnected grid. To efficiently utilize the resources load-following and regulation problems are stated. The efficacy of proposed fuel input control designs in enhancing the dynamic response rates is illustrated on IEEE 14-bus system. Second, the problem is formalized as multi-input multioutput time-varying trajectory tracking based on a decentralized spatiotemporal composite control design. The concepts of vector-Lyapunov function and singular perturbation are invoked to formalize model decompositions, over space and time, respectively. Next, the assumptions for model simplifications are relaxed and the problem of parametric uncertainty is addressed. A minimumcost resilient co-design approach is introduced for storage-sensors-communication channels in a complex electric power grid. The notion of selective strong structural fixed modes is explored as a characterization of feasible decentralized control laws for an arbitrary system realization satisfying a pre-specified structure. Finally, it is proposed that planning of generation portfolio must be driven by the objective of maintaining adequate operating flexibility in the system. The goal is to ensure sufficient ramp capacity to sustain the significant integration of intermittent renewable resources.

description: Turbulent motions in stellar convection zones generate acoustic energy, part of which is then supplied to normal modes of the star. Their amplitudes result from a balance between the efficiencies of excitation and damping processes in the convection zones. We develop a formalism that provides the excitation rates of non-radial global modes excited by turbulent convection. As a first application, we estimate the impact of non-radial effects on excitation rates and amplitudes of high-angular-degree modes which are observed on the Sun. A model of stochastic excitation by turbulent convection has been developed to compute the excitation rates, and it has been successfully applied to solar radial modes (Samadi & Goupil 2001, Belkacem et al. 2006b). We generalize this approach to the case of non-radial global modes. This enables us to estimate the energy supplied to high-($\ell$) acoustic modes. Qualitative arguments as well as numerical calculations are used to illustrate the results. We find that non-radial effects for $p$ modes are non-negligible: - for high-$n$ modes (i.e. typically $n > 3$) and for high values of $\ell$; the power supplied to the oscillations depends on the mode inertia. - for low-$n$ modes, independent of the value of $\ell$, the excitation is dominated by the non-diagonal components of the Reynolds stress term. We carried out a numerical investigation of high-$\ell$ $p$ modes and we find that the validity of the present formalism is limited to $\ell < 500$ due to the spatial separation of scale assumption. Thus, a model for very high-$\ell$ $p$-mode excitation rates calls for further theoretical developments, however the formalism is valid for solar $g$ modes, which will be investigated in a paper in preparation.

Multi-Goal Path Optimization for Robotic Systems with Redundancy based on the Traveling Salesman Problem with Neighborhoods

description: Finding an optimal path for a redundant robotic system to visit a sequence of several goal locations is a complex optimization problem and poses two main technical challenges. Because of the redundancy in the system, the robot can assume an infinite number of goal configurations to reach each goal location. Therefore, not only an optimal sequence of the goals has to be defined, but also, for each goal, an optimal configuration has to be chosen among infinite possibilities. Second, the actual cost for the system to move from one configuration to the next depends on many factors, such as obstacle avoidance or energy consumption, and can be calculated only through the employment of specific path planning techniques.
We first address the optimization problem of finding an optimal sequence of optimal configurations, while assuming the cost function to be analytically defined. This problem is modeled as a Traveling Salesman Problem with Neighborhoods (TSPN), which extends the well-known TSP to more general cases where each vertex (goal configuration) is allowed to move in a given region (neighborhood). In the literature, heuristic solution approaches are available for TSPN instances with only circular or spherical neighborhoods. For more general neighborhood topologies, but limited to the Euclidean norm as edge weighting function, approximation algorithms have also been proposed. We present three novel approaches: (1) a global Mixed Integer Non Linear Programming (MINLP) optimizer and (2) a convex MINLP optimizer are modified to solve to optimality TSPN instances with up to 20 convex neighborhoods, and (3) a hybrid random-key Genetic Algorithm (GA) is developed to address more general problems with a larger number of possibly non-convex neighborhoods and with different types of edge weighting functions. Benchmark tests show that the GA is able to find the same optimal tour calculated by the MINLP solvers while drastically reducing the computational cost, and it always improves the best known solutions for available test problems with up to 1,000 neighborhoods.
Second, we integrate the GA with a probabilistic path planning technique to apply the proposed procedure to two practical applications. We minimize the time currently required by an industrial vision inspection system to complete a multi-goal cycle, where the neighborhoods are defined using piecewise cubic splines in a seven-dimensional configuration space. Afterwards, we optimize the flight path and the energy consumption of a quadrotor Unmanned Aerial Vehicle (UAV) on an urban survey mission. The specifications of the camera installed on the UAV are used here to define the neighborhoods as three-dimensional polyhedra.

description: We present the results of our recent studies of a Thick Gaseous Electron Multiplier (THGEM)-based detector, operated in Ar, Xe and Ar:Xe (95:5) at various gas pressures. Avalanche-multiplication properties and energy resolution were investigated with soft x-rays for different detector configurations and parameters. Gains above 10E4 were reached in a double-THGEM detector, at atmospheric pressure, in all gases, in almost all the tested conditions; in Ar:Xe (95:5) similar gains were reached at pressures up to 2 bar. The energy resolution dependence on the gas, pressure, hole geometry and electric fields was studied in detail, yielding in some configurations values below 20% FWHM with 5.9 keV x-rays.

description: In Pickup and Delivery Problems (PDPs), mobile vehicles retrieve and deliver a set of items. The PDP is a well-studied, NP-hard problem. Examples of the PDP include mail and courier services, taxis, ridesharing services, and robots such as our own CoBots and CreBots, which retrieve and deliver items for the occupants of a building, and are the motivation for this thesis. The goal of the PDP is to find a schedule that delivers as many items as possible at the lowest cost, under various constraints such as time windows and vehicle capacities. We augment the PDP with transfers to form the PDP with Transfers (PDP-T). Instead of having a single vehicle retrieve and deliver each item, vehicles can transfer items to other vehicles (or chains of vehicles) for delivery. Allowing transfers makes lower cost solutions feasible, but increases the number of possible schedules exponentially. In this thesis, we contribute a series of algorithms to form schedules for variants of the PDP-T. We introduce the Very Large Neighborhood Search with Transfers (VLNS-T) algorithm to plan schedules for the most general version of the PDP-T, with constraints including time windows, capacities, vehicle start and end locations, maximum item transport times, and maximum vehicle route durations. We also contribute algorithms for simplified variants of the PDP-T, which take advantage of the problem structure to find solutions more quickly and more effectively than the general algorithm for specific PDP-T variants, some with provable guarantees. We also study the challenges of deploying PDP-T schedules on physical robots, and execute PDP-T schedules on the CoBots. The robots reschedule their tasks in response to new requests, delays, failures, and shared information from other robots. We also introduce the CreBots, which transfer items fully autonomously. Our PDP-T algorithms are evaluated on benchmark problems, on the CoBots, and on problems on city maps sampled from real world taxi data, demonstrating that lower cost schedules can be found with transfers.

description: In Autumn, 2018, I began working to set up a research data repository at the Royal Veterinary College, University of London, working primarily with Dr. Dan O'Neill, an epidemiologist. The resulting efforts offer some instructive insight into the challenges and opportunities presented for librarians and research support staff by open repositories, and specifically the expectation, increasingly held by researchers, that technical and administrative support in the matter of open data be available to them via their institution's library and/or IT services. The poster documents, visually and descriptively, the different parties and systems involved in the effort to support what remains a relatively nascent expectation among researchers. This expectation, in turn, has been generated by external (expectations of peer reviewers, grant funder policy), institutional (research data policies specific to their institution), and professional (effective techniques for collaboration, intellectual property concerns related to use of commercial repositories) responsibilities. This poster looks at the different concepts and stakeholders represented in a local project in an attempt to draw out some widely applicable truths and recommendations.

description: We demonstrate a method that merges the quantum filter diagonalization (QFD) approach for hybrid quantum/classical solution of the time-independent electronic Schrödinger equation with a low-rank double factorization (DF) approach for the representation of the electronic Hamiltonian. In particular, we explore the use of sparse "compressed" double factorization (C-DF) truncation of the Hamiltonian within the time-propagation elements of QFD, while retaining a similarly compressed but numerically converged double-factorized representation of the Hamiltonian for the operator expectation values needed in the QFD quantum matrix elements. Together with significant circuit reduction optimizations and number-preserving post-selection/echo-sequencing error mitigation strategies, the method is found to provide accurate predictions for low-lying eigenspectra in a number of representative molecular systems, while requiring reasonably short circuit depths and modest measurement costs. The method is demonstrated by experiments on noise-free simulators, decoherence- and shot-noise including simulators, and real quantum hardware.

description: In this paper, we explore a new avenue to a natural explanation of the observed tiny neutrino masses with a dynamical realization of the three-generation structure in the neutrino sector. Under the magnetized background based on $T^2/Z_2$, matter consists of multiply-degenerated zero modes and the whole intergenerational structure is dynamically determined. In this sense, we can conclude that our scenario is favored by minimality, where no degree of freedom remains to deform the intergenerational structure by hand freely. Under the consideration of brane-localized Majorana-type mass terms for an $SU(2)_L$ singlet neutrino, it is sufficient to introduce one Higgs doublet for reproducing the observed neutrino data. In all reasonable flux configurations with three right-handed neutrinos, phenomenologically acceptable parameter configurations are found.
