description: Understanding the physics of structurally and chemically complex transition-metal oxide and polyanionic materials such as those used for battery electrodes is challenging, even at the level of pristine compounds. Yet these materials are also prone to and their properties and performance are strongly affected or even determined by crystallographic point defects. In this review, we highlight recent advances in the study of defects and doping in such materials using first-principles calculations. The emphasis is on describing a theoretical and computational approach that has the ability to predict defect landscapes under various synthesis conditions, provide guidelines for defect characterization and defect-controlled synthesis, uncover the mechanisms for electronic and ionic conduction and electrochemical extraction and (re-)insertion, and provide an understanding of the effects of doping. Though applied to battery materials here, the approach is general and applicable to any materials in which the defect physics plays a role or drives the properties of interest. Thus, this work is intended as an in-depth review of defect physics in particular classes of materials, but also as a methodological template for the understanding and design of complex functional materials.

description: This research is an attempt to coalesce sociology and psychoanalysis and to approach less palpable and more insidious aspects of xenophobia. I have used the Lacanian concept of perversion to address the question of xenophobia as a recurrent phenomenon. Once again, xenophobia has reached the point where Europe’s death is seen imminent by neo-conservatives like Douglas Murray whose book, The Strange Death of Europe; Immigration, Identity, Islam has been my case of study. This is an attempt at understanding xenophobia as a social problem characterized by an essential corporeality that has been neglected in social sciences. I suggest that the xenophobic is the perverse who is calling on the father to stop the flow of abjects into the house. The abjects are Unheimliche in Lacan’s terms whose appearance in the house has caused phobia in the perverse. In a precise manner, I will practically analyze xenophobia enunciated by Murray in his book and in the end I will suggest what has to be borne in mind in treating xenophobia whose subject is desperately calling for a charismatic leader to show face and lead him to terminate the flow of migration. The xenophobic is making scenery that is a necessity for him to feel satisfied. If the EU forgets her part and is incapable of playing her part in the xenophobic’s fantasy the scene collapses.
Energy Decay in Burgers Turbulence and Interface Growth. the Problem of Random Initial Conditions - II

description: We present a study of the Burgers equation in one and two dimensions $d=1,2$ following the analytic approach indicated in the previous paper I. For the problem of the initial conditions decay we consider two classes of initial condition distributions $Q_{1,2} \sim \exp[-(1/4D)\int({\nabla}h)^2$d{\bf x}] where $h$-field is unbounded ($Q_1$) or bounded ($Q_2, |h|\leq H$). Avoiding the replica trick and using an integral representation of the logarithm we study the tractable field theory which has $d=2$ as a critical dimension. It is shown that the degenerate one-dimensional case has three stages of decay, when the kinetic energy density diminishes with time as $t^{-2/3}$, $t^{-2}$, $t^{-3/2}$ contrary to the predictions of the similarity hypothesis based on the second-order correlator of the distribution. In two dimensions we find the kinetic energy decay which is proportional to $t^{-1}\ln^{-1/2}(t)$. It is shown that the pure diffusion equation with the $Q_2$-type initial condition has non-trivial energy decay exponents indicating connection with the $O(2)$ non-linear $σ$-model.

Instanton Calculus and Loop Operator in Supersymmetric Gauge Theory

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We compute one-point function of the glueball loop operator in the maximally confining phase of supersymmetric gauge theory using instanton calculus. In the maximally confining phase the residual symmetry is the diagonal U(1) subgroup and the localization formula implies that the chiral correlation functions are the sum of the contributions from each fixed point labeled by the Young diagram. The summation can be performed exactly by operator formalism of free fermions, which also featured in the equivariant Gromov-Witten theory of P^1. By taking the Laplace transformation of the glueball loop operator, we find an exact agreement with the previous results for the generating function (resolvent) of the glueball one-point functions.

Ashtekar variables, self-dual metrics and w-infinity
Creators: name: Husain, Viqar
Publisher: name: arXiv
Year: 1992
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The self-duality equations for the Riemann tensor are studied using the Ashtekar Hamiltonian formulation for general relativity. These equations may be written as dynamical equations for three divergence free vector fields on a three dimensional surface in the spacetime. A simplified form of these equations, describing metrics with a one Killing field symmetry are written down, and it shown that a particular sector of these equations has a Hamiltonian form where the Hamiltonian is an arbitrary function on a two-surface. In particular, any element of the $w_\infty$ algebra may be chosen as a the Hamiltonian. For a special choice of this Hamiltonian, an infinite set of solutions of the self-duality equations are given. These solutions are parametrized by elements of the $w_\infty$ algebra, which in turn leads to an explicit form of four dimensional complex self-dual metrics that are in one to one correspondence with elements of this algebra.

description: We report the experimental observation of commensurability oscillations (COs) in 1D graphene superlattices. The widely tunable periodic potential modulation in hBN encapsulated graphene is generated via the interplay of nanopatterned few layer graphene acting as a local bottom gate and a global Si back gate. The longitudinal magneto-resistance shows pronounced COs, when the sample is tuned into the unipolar transport regime. We observe up to six CO minima, providing evidence for a long mean free path despite the potential modulation. Comparison to existing theories shows that small angle scattering is dominant in hBN/graphene/hBN heterostructures. We observe robust COs persisting to temperature exceeding $T=150$ K. At high temperatures, we find deviations from the predicted $T$-dependence, which we ascribe to electron-electron scattering.

description: The Internet of Things (IoT) realizes a vision where billions of interconnected devices are deployed just about everywhere, from inside our bodies to the most remote areas of the globe. As the IoT will soon pervade every aspect of our lives and will be accessible from anywhere, addressing critical IoT security threats is now more important than ever. Traditional approaches where security is applied as an afterthought and as a "patch" against known attacks are insufficient. Indeed, next-generation IoT challenges will require a new secure-by-design vision, where threats are addressed proactively and IoT devices learn to dynamically adapt to different threats. To this end, machine learning and software-defined networking will be key to provide both reconfigurability and intelligence to the IoT devices. In this paper, we first provide a taxonomy and survey the state of the art in IoT security research, and offer a roadmap of concrete research challenges related to the application of machine learning and software-defined networking to address existing and next-generation IoT security threats.

National Roadmap

description: Developing countries have begun to take strong steps in open access publishing through open repositories, however, they face significant challenges that may differ from those in developed countries, most notably the lack of resources at the institutional level, as well as the political and geographic constraints that reduce the incentive for open repositories adoption. Developing countries also have special needs at the user level, specifically with regard to the language used in open repository systems. The existence of solutions at the national or perhaps regional level will contribute to encouraging institutions in these countries to adopt open repositories, especially if these solutions come to remove most of the burden on institutions to develop, customize, and maintain these open repositories. In this presentation, we will introduce ROMOR, a project funded by the Erasmus+ program, as one of the initiatives for building open institutional repositories in Palestine. We will discuss with the conference participants ROMOR's future vision for a national solution to support open access publishing.
Safety-critical Geometric Control Design with Application to Aerial Transportation
Creators: name: Guofan  Wu
Publisher: name: Carnegie Mellon University
Year: 2017
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: Safety constraints are ubiquitous in many robotic applications. For instance, aerial robots such as quadrotors or hexcoptors need to realize fast collision-free flight, and bipedal robots have to choose their discrete footholds properly to gain the desired friction and pressure contact forces. In this thesis, we address the safety critical control problem for fully-actuated and under-actuated mechanical systems. Since many mechanical systems evolve on nonlinear manifolds, we extend the concept of Control Barrier Function to a new concept called geometric Control Barrier Function which is specifically designed to handle safety constraints on manifolds. This type of Control Barrier Function stems from geometric control techniques and has a coordinate free and compact representation. In a similar fashion, we also extend the concept of Control Lyapunov Function to the concept of geometric Control Lyapunov Function to realize tracking on the manifolds. Based on these new geometric versions of CLF and CBF, we propose a general control design method for fully-actuated systems with both state and input constraints. In this CBF-CLF-QP control design, the control input is computed based on a state-dependent Quadratic Programming (QP) where the safety constraints are strictly enforced using geometric CBF but the tracking constraint is imposed through a type of relaxation. Through this type of relaxation, the controller could still keep the system state safe even in the cases when the reference is unsafe during some time period. For a single quadrotor, we propose the concept of augmented Control Barrier Function specifically to let it avoid external obstacles. Using this augmented CBF, we could still utilize the idea of CBF-CLF-QP controller in a sequential QP control design framework to let this quadrotor remain safe during the flight. In meantime, we also apply the geometric control techniques to the aerial transportation problem where a payload is carried by multiple quadrotors through cable suspension. This type of transportation method allows multiple quadrotors to share the payload weight, but introduces internal safety constraints at the same time. By employing both linear and nonlinear techniques, we are able to carry the payload pose to follow a pre-defined reference trajectory.
The modulation of the gamma-ray emission from the binary LS 5039

description: Gamma-ray binaries, composed of a massive star and compact object, have been established as a new class of sources of very high energy (VHE) photons. The gamma-rays are produced by inverse Compton scattering of the stellar light by VHE electrons accelerated in the vicinity of the compact object. The VHE emission from LS 5039 displays an orbital modulation. The inverse Compton spectrum depends on the angle between the incoming and outgoing photon in the electron rest frame. Since the angle at which an observer sees the star and electrons changes with the orbit, a phase dependence of the spectrum is expected. The phase-dependent spectrum of LS 5039 is calculated, assuming a continuous injection of electrons. The shape of the electron distribution depends on the injected power-law and on the magnetic field intensity. Anisotropic scattering produces hard emission at inferior conjunction, when attenuation due to pair production of the VHE gamma-rays on star light is minimum. The computed lightcurve and spectra provide good fits to the HESS and EGRET observations, except at phases of maximum attenuation where pair cascade emission may be significant for HESS. Detailed predictions are made for a modulation in the GLAST energy range. The magnetic field intensity at periastron is 0.8+-0.2 G. Anisotropic inverse Compton scattering plays a major role in LS 5039. The derived magnetic field intensity, injection energy and slope suggest a rotation-powered pulsar wind nebula. Gamma-ray binaries are promising sources to study the environment of pulsars on small scales.

description: We present a measurement of the galaxy merger fraction and number density from observations in the Hubble Ultra Deep Field for 0.510^10 M_sol. When correcting for mass incompleteness, the major merger fraction is not simply proportional to (1+z)^m, but appears to peak at z_frac~=1.3+-0.4. From this merger fraction, we infer that ~42% of massive galaxies have undergone a major merger since z~1. We show that the major merger number density peaks at z_dens~1.2, which marks the epoch where major merging of massive galaxies is most prevalent. This critical redshift is comparable to the peak of the cosmic star formation rate density, and occurs roughly 2.6 Gyr earlier in cosmic time than the peak in the number density of X-ray selected active galactic nuclei. These observations support an indirect evolutionary link between merging, starburst, and active galaxies.

description: We analyse the dispersion properties of two types of explicit finite element methods for modelling acoustic and elastic wave propagation on tetrahedral meshes, namely mass-lumped finite element methods and symmetric interior penalty discontinuous Galerkin methods, both combined with a suitable Lax--Wendroff time integration scheme. The dispersion properties are obtained semi-analytically using standard Fourier analysis. Based on the dispersion analysis, we give an indication of which method is the most efficient for a given accuracy, how many elements per wavelength are required for a given accuracy, and how sensitive the accuracy of the method is to poorly shaped elements.

Non-perturbative solutions of the multi-critical unitary matrix models map to non-singular solutions of the `renormalisation group' equation for the string susceptibility, $[\tilde{P},Q]=Q$. We also demonstrate that the large N solutions of unitary matrix integrals in external fields, studied by Gross and Newman, equal the non-singular pure closed-string solutions of $[\tilde{P},Q]=Q$.

description: We present a concise method to construct a BRST invariant action for the topological quantum field theories in the Batalin-Vilkovisky antifield formalism. The BV action that is a solution for the master equation is directly obtained by means of the extended forms that involve all the required ghosts and antifields. The BV actions for the non-abelian $BF$ theories (in 4 and higher dimensions) and the Chern-Simons theory are constructed by means of the extended form method. An extension of the $BF$ theory in 4-dimensions to include a ``cosmological term'' is also examined and the close connection with the topological Yang-Mills theory is indicated.

description: We investigate the Schwinger pair production phenomena in spatially homogeneous strong electric fields. We first consider scalar QED in four-dimensions and discuss the potential ambiguity in the adiabatic order assignment for the electromagnetic potential required to fix the renormalization subtractions. We argue that this ambiguity can be solved by invoking the conformal anomaly when both electric and gravitational backgrounds are present. We also extend the adiabatic regularization method for spinor QED in two-dimensions and find consistency with the chiral anomaly. We focus on the issue of the renormalization of the electric current $\langle j^μ\rangle$ generated by the created pairs. We illustrate how to implement the renormalization of the electric current for the Sauter pulse.

Robust Rearrangement Planning Using Nonprehensile Interaction
Creators: name: King, Jennifer E.
Publisher: name: Carnegie Mellon University
Year: 2016
Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics
subject: FOS: Computer and information sciences

description: As we work to move robots out of factories and into human environments, we must empower robots to interact freely in unstructured, cluttered spaces. Humans do this easily, using diverse, whole-arm, nonprehensile actions such as pushing or pulling in everyday tasks. These interaction strategies make difficult tasks easier and impossible tasks possible. In this thesis, we aim to enable robots with similar capabilities. In particular, we formulate methods for planning robust open-loop trajectories that solve the rearrangement planning problem using nonprehensile interactions. In these problems, a robot must plan in a cluttered environment, reasoning about moving multiple objects in order to achieve a goal. The problem is difficult because we must plan in continuous, high-dimensional state and action spaces. Additionally, during planning we must respect the physical constraints induced by the nonprehensile interaction between the robot and the objects in the scene. Our key insight is that by embedding physics models directly into our planners we can naturally produce solutions that use nonprehensile interactions such as pushing. This also allows us to easily generate plans that exhibit full arm manipulation and simultaneous object interaction without the need for programmer defined high-level primitives that specifically encode this interaction. We show that by generating these diverse actions, we are able to find solutions for motion planning problems in highly cluttered, unstructured environments. In the first part of this thesis we formulate the rearrangement planning problem as a classical motion planning problem. We show that we can embed physics simulators into randomized planners. We propose methods for reducing the search space and speeding planning time in order to make the planners useful in real-world scenarios. The second part of the thesis tackles the imperfect and imprecise worlds that reflect the true reality for robots working in human environments. We pose the rearrangement planning under uncertainty problem as an instance of conformant probabilistic planning and offer methods for solving the problem. We demonstrate the effectiveness of our algorithms on two platforms: the home care robot HERB and the NASA rover K-Rex. We demonstrate expanded autonomous capability on HERB, allowing him to work better in high clutter, completing previously infeasible tasks and speeding feasible task execution. In addition, we show these planners increase autonomy for the NASA rover K-Rex by allowing the rover to actively interact with the environment.

description: One aim of the equal load sharing fiber bundle model is to describe the critical behavior of failure events. One way of accomplishing this, is through a discrete recursive dynamics. We introduce a continuous mesoscopic equation catching the critical behavior found through recursive dynamics. It allows us to link the model with the unifying framework of absorbing phase transitions traditionally used in the study of non-equilibrium phase transitions. Moreover, it highlights the analogy between equal load sharing and spinodal nucleation. Consequently, this work is a first step towards the quest of a field theory for fiber bundle models.

Statistical upper bounds are provided for the Kullback-Leiber divergence and the $\ell_2$ risk between the estimator and the true transition matrix. The estimator reveals a compressed state space of the Markov chain. We also develop a novel DC (difference of convex function) programming algorithm to tackle the rank-constrained non-smooth optimization problem. Convergence results are established. Experiments show that the proposed estimator achieves better empirical performance than other popular approaches.

description: We report the serendipitous discovery of a dusty, starbursting galaxy at $z=5.667$ (hereafter called CRLE) in close physical association with the "normal" main-sequence galaxy HZ10 at $z=5.654$. CRLE was identified by detection of [CII], [NII] and CO(2-1) line emission, making it the highest redshift, most luminous starburst in the COSMOS field. This massive, dusty galaxy appears to be forming stars at a rate of at least 1500$\,M_\odot$ yr$^{-1}$ in a compact region only $\sim3$ kpc in diameter. The dynamical and dust emission properties of CRLE suggest an ongoing merger driving the starburst, in a potentially intermediate stage relative to other known dusty galaxies at the same epoch. The ratio of [CII] to [NII] may suggest that an important ($\sim15\%$) contribution to the [CII] emission comes from a diffuse ionized gas component, which could be more extended than the dense, starbursting gas. CRLE appears to be located in a significant galaxy overdensity at the same redshift, potentially associated with a large-scale cosmic structure recently identified in a Lyman Alpha Emitter survey. This overdensity suggests that CRLE and HZ10 reside in a protocluster environment, offering the tantalizing opportunity to study the effect of a massive starburst on protocluster star formation. Our findings support the interpretation that a significant fraction of the earliest galaxy formation may occur from the inside out, within the central regions of the most massive halos, while rapidly evolving into the massive galaxy clusters observed in the local Universe.

description: We look at the prospects for detecting light bosons, $X$, at proposed Z factories assuming a production of $10^{12}$ Z bosons. Such a large yield is within the design goals of future FCC-ee and CEPC colliders. Specifically we look at the cases where $X$ is either a singlet scalar which mixes with the standard model Higgs or a vector boson with mass $1\lesssim M_X \lesssim 80$ GeV. We find that several channels are particularly promising for discovery prospects. In particular $Z\rightarrow f \bar{f} X$ and $Z \rightarrow V_Q X$ gives a promising signal above a very clean standard model background. We also discuss several channels that have too large a background to be useful.

OA Theses: Demonstrating value and addressing concerns of students and their supervisors
Creators: name: McKnight, Jenny
Publisher: name: Zenodo
Year: 2019
Subjects: Open Access theses; Open Access policies; Open Access—outreach and engagement

description: In 2017, the University of Melbourne introduced a revised thesis access policy. Under this revised policy, open access became 'opt out' rather than 'opt in' for students and the default embargo period was reduced from seven years to two. Whilst these changes were welcomed by many members of the university community, they also served to generate a degree of anxiety in many quarters: what was the value of these changes? Would this new policy facilitate plagiarism of student work? And (by far the most the most common concern raised) would it prevent students publishing from their thesis? This paper will explore a number of initiatives undertaken at the university to address these concerns at a local level and increase confidence amongst graduate research students, and their supervisors, in making their theses OA.
Correlation between Dzyaloshinskii Moriya interaction and spin mixing conductance at antiferromagnet / ferromagnet interface

description: The rich interaction phenomena at antiferromagnet (AFM)/ ferromagnet (FM) interfaces are key ingredients in AFM spintronics, where many underlying mechanisms remain unclear. Here we report a correlation observed between interfacial Dzyaloshinskii-Moriya interaction (DMI) Ds and effective spin mixing conductance g at IrMn/CoFeB interface. Both Ds and g are quantitatively determined with Brillouin light scattering measurements, and increase with IrMn thickness in the range of 2.5~7.5 nm. Such correlation likely originates from the AFM-states-mediated spin-flip transitions in FM, which promote both interfacial DMI and spin pumping effect. Our findings provide deeper insight into the AFM-FM interfacial coupling for future spintronic design.

ROSI – Open Metrics for Open Repositories

description: Researchers rely more and more on online tools to conduct their research. In theory, the growing need for comprehensive information about online research outputs could be easily satisfied. Yet, the majority of scientometric sources are not completely open, which generates intransparent data and limits impact assessments. To illustrate, some proprietary databases that generate scientometric indicators do not disclose the raw data for users beyond traditional subscription-based models. At the same time, researchers' needs concerning scientometric indicators are not addressed adequately by these existing products. In contrast, the project ROSI (Reference Implementation for Open Scientific Indicators) focuses only on open data sources. A reference implementation to visualise related metrics from open data sources, such as open access repositories, will be developed. Throughout the project, the needs of researchers concerning scientometric indicators are gathered in an iterative process, and researchers will be invited to evaluate the project outcomes. The reference implementation will be documented in a user handbook and will be reusable in other contexts, such as research information systems, repositories and publishing software.
Spectral properties of the one-dimensional Hubbard model

description: The spectral properties of the 1-D Hubbard model are obtained from quantum Monte Carlo simulations using the maximum entropy method. The one-particle excitations are characterized by dispersive cosine-like bands. Velocities for spin- and charge excitations are obtained that lead to a conformal charge c=0.98 +/- 0.05 for the largest system simulated (N=84). An exact sum-rule for the spin-excitations is fulfilled accurately with deviations of at most 10% only around 2 kF.

description: We consider the full probability distribution for the transverse magnetization of a finite subsystem in the transverse field Ising chain. We derive a determinant representation of the corresponding characteristic function for general Gaussian states. We consider applications to the full counting statistics in the ground state, finite temperature equilibrium states, non-equilibrium steady states and time evolution after global quantum quenches. We derive an analytical expression for the time and subsystem size dependence of the characteristic function at sufficiently late times after a quantum quench. This expression features an interesting multiple light-cone structure.

description: Based on 1-minute price changes recorded since year 2012, the fluctuation properties of the rapidly-emerging Bitcoin (BTC) market are assessed over chosen sub-periods, in terms of return distributions, volatility autocorrelation, Hurst exponents and multiscaling effects. The findings are compared to the stylized facts of mature world markets. While early trading was affected by system-specific irregularities, it is found that over the months preceding Apr 2018 all these statistical indicators approach the features hallmarking maturity. This can be taken as an indication that the Bitcoin market, and possibly other cryptocurrencies, carry concrete potential of imminently becoming a regular market, alternative to the foreign exchange (Forex). Since high-frequency price data are available since the beginning of trading, the Bitcoin offers a unique window into the statistical characteristics of a market maturation trajectory.
Multi-messenger gamma-ray counterpart of the IceCube neutrino signal

description: A signal of high-energy extraterrestrial neutrinos from unknown source(s) was recently discovered by the IceCube experiment. Neutrinos are always produced together with gamma-rays, but the gamma-ray flux from extragalactic sources is suppressed due to attenuation in the intergalactic medium. We report the discovery of a gamma-ray excess at high Galactic latitudes starting at energies 300 GeV in the data of the Fermi telescope. We show that the multi-TeV gamma-ray diffuse emission has spectral characteristics at both low and high Galactic latitudes compatible with those of the IceCube high neutrino signal in the same sky regions. This suggests that these gamma-rays are the counterpart of the IceCube neutrino signal, implying that a sizable part of the IceCube neutrino flux originates from the Milky Way. We argue that the diffuse neutrino and gamma-ray signal at high Galactic latitudes originates either from previously unknown nearby cosmic ray "PeVatron" source(s), an extended Galactic CR halo or from decays of heavy dark matter particles.
