description: Noisy, intermediate-scale quantum (NISQ) systems are expected to have a few hundred qubits, minimal or no error correction, limited connectivity and limits on the number of gates that can be performed within the short coherence window of the machine. The past decade's research on quantum programming languages and compilers is directed towards large systems with thousands of qubits. For near term quantum systems, it is crucial to design tool flows which make efficient use of the hardware resources without sacrificing the ease and portability of a high-level programming environment. In this paper, we present a compiler for the Scaffold quantum programming language in which aggressive optimization specifically targets NISQ machines with hundreds of qubits. Our compiler extracts gates from a Scaffold program, and formulates a constrained optimization problem which considers both program characteristics and machine constraints. Using the Z3 SMT solver, the compiler maps program qubits to hardware qubits, schedules gates, and inserts CNOT routing operations while optimizing the overall execution time. The output of the optimization is used to produce target code in the OpenQASM language, which can be executed on existing quantum hardware such as the 16-qubit IBM machine. Using real and synthetic benchmarks, we show that it is feasible to synthesize near-optimal compiled code for current and small NISQ systems. For large programs and machine sizes, the SMT optimization approach can be used to synthesize compiled code that is guaranteed to finish within the coherence window of the machine.

description: The stabilities of $(BN)_x(C_2)_{1-x}$ alloys and related superlattices are investigated by ab initio pseudopotential calculations. We find that the $(BN)_1/(C_2)_1$ superlattices in (111) orientations have the lowest formation energy among many short-range ordered $BNC_2$ structures due to the smallest number of B-C and C-N bonds. Based on the calculated formation energies at several compositions and for various ordered structures and assuming thermodynamic equilibrium, the solid solution phase diagram of $(BN)_x(C_2)_{1-x}$ alloys is constructed. We find that the complete miscibility of $(BN)_x(C_2)_{1-x}$ alloys is possible, which is in contrast with previous theoretical predictions but in agreement with experimental reports.

description: We theoretically investigate the Goos-Hänchen (GH) effect of spin-wave beams reflected from the interface between two ferromagnetic films with different Dzyaloshinskii-Moriya interactions (DMIs). The formula of the GH shift as functions of the incident angle and material parameters is derived analytically. We show that the GH effect occurs only when spin waves are totally reflected at the interface and vanishes otherwise. We further explore the GH shift of spin waves by narrow DMI strips of different widths. It is found that the induced shift is independent of the strip width down to $10$ nm, offering a novel approach to measure the DMI strength of ultra-narrow magnetic strips which is out the scope of current technology. Full micromagnetic simulations compare well with our theoretical findings. Strong distortion of edge magnetizations for narrower strips however generates a width dependence of the GH shift. The results presented in this work are helpful for understanding the GH effect in chiral magnets and for quantifying the DMI parameter in magnetic strips of sub-$50$ nm scales.

description: The capability to perform facial analysis from video sequences has significant potential to positively impact in many areas of life. One such area relates to the medical domain to specifically aid in the diagnosis and rehabilitation of patients with facial palsy. With this application in mind, this paper presents an end-to-end framework, named 3DPalsyNet, for the tasks of mouth motion recognition and facial palsy grading. 3DPalsyNet utilizes a 3D CNN architecture with a ResNet backbone for the prediction of these dynamic tasks. Leveraging transfer learning from a 3D CNNs pre-trained on the Kinetics data set for general action recognition, the model is modified to apply joint supervised learning using center and softmax loss concepts. 3DPalsyNet is evaluated on a test set consisting of individuals with varying ranges of facial palsy and mouth motions and the results have shown an attractive level of classification accuracy in these task of 82% and 86% respectively. The frame duration and the loss function affect was studied in terms of the predictive qualities of the proposed 3DPalsyNet, where it was found shorter frame duration's of 8 performed best for this specific task. Centre loss and softmax have shown improvements in spatio-temporal feature learning than softmax loss alone, this is in agreement with earlier work involving the spatial domain.

description: The interplane optical spectrum of the organic superconductor kappa-(BEDT-TTF)2Cu[N(CN)2]Br was investigated in the frequency range from 40 to 40,000 cm-1. The optical conductivity was obtained by Kramers-Kronig analysis of the reflectance. The absence of a Drude peak at low frequency is consistent with incoherent conductivity but in apparent contradiction to the metallic temperature dependence of the DC resistivity. We set an upper limit to the interplane transfer integral of tb = 0.1 meV. A model of defect-assisted interplane transport can account for this discrepancy. We also assign the phonon lines in the conductivity to the asymmetric modes of the ET molecule.

Der Beitrag gibt eine Definition der neuen Disziplin (1), untersucht die Rolle des Konzeptes Migration in der Populationsgenetik (2) und beschreibt den Stand der Migrationsforschung in der Mediävistik (3). Anschließend gibt er einen kurzen Überblick über die von der Genetic History untersuchten Migrationsräume (4), betrachtet exemplarisch zunächst eine Studie zur angelsächsischen Migration nach Britannien (5) und dann ein aktuelles Projekt, in dem erstmals ein Mediävist die Leitung innehat (6). Der Beitrag endet mit einigen allgemeinen Beobachtungen und Postulaten (7).
description: Genetic History is the study of historical questions with DNA as a source. Migrations are its main subject. It is thus very relevant to Medieval Studies. Yet until recently historians have not been involved. The contribution provides a definition of the new discipline (1), explores the role of migration as a concept in Population Genetics (2) and describes the state of migration studies in Medieval History (3). It then sets out for an overview of medieval migratory areas studied by Genetic History (4) and takes an exemplary look first (5) at a study on Anglo-Saxon migration to Britain and later (6) at a current project where for the first time a medieval historian has taken the lead. The contribution ends (7) with some general observations and stipulations.

description: We develop a novel hierarchy for zero-dimensional persistence pairs, i.e., connected components, which is capable of capturing more fine-grained spatial relations between persistence pairs. Our work is motivated by a lack of spatial relationships between features in persistence diagrams, leading to a limited expressive power. We build upon a recently-introduced hierarchy of pairs in persistence diagrams that augments the pairing stored in persistence diagrams with information about which components merge. Our proposed hierarchy captures differences in branching structure. Moreover, we show how to use our hierarchy to measure the spatial stability of a pairing and we define a rank function for persistence pairs and demonstrate different applications.

description: Techniques from computational topology, in particular persistent homology, are becoming increasingly relevant for data analysis. Their stable metrics permit the use of many distance-based data analysis methods, such as multidimensional scaling, while providing a firm theoretical ground. Many modern machine learning algorithms, however, are based on kernels. This paper presents persistence indicator functions (PIFs), which summarize persistence diagrams, i.e., feature descriptors in topological data analysis. PIFs can be calculated and compared in linear time and have many beneficial properties, such as the availability of a kernel-based similarity measure. We demonstrate their usage in common data analysis scenarios, such as confidence set estimation and classification of complex structured data.

description: We study the orientational dynamics of infinitely thin hard rods of length L, with the centers-of-mass fixed on a simple cubic lattice with lattice constant a.We approximate the influence of the surrounding rods onto dynamics of a pair of rods by introducing an effective rotational diffusion constant D(l),l=L/a. We get D(l) ~ [1-v(l)], where v(l) is given through an integral of a time-dependent torque-torque correlator of an isolated pair of rods. A glass transition occurs at l_c, if v(l_c)=1. We present a variational and a numerically exact evaluation of v(l).Close to l_c the diffusion constant decreases as D(l) ~ (l_c-l)^γ, with γ=1. Our approach predicts a glass transition in the absence of any static correlations, in contrast to present form of mode coupling theory.

description: Deterministic interpolation and quadrature methods are often unsuitable to address Bayesian inverse problems depending on computationally expensive forward mathematical models. While interpolation may give precise posterior approximations, deterministic quadrature is usually unable to efficiently investigate an informative and thus concentrated likelihood. This leads to a large number of required expensive evaluations of the mathematical model. To overcome these challenges, we formulate and test a multilevel adaptive sparse Leja algorithm. At each level, adaptive sparse grid interpolation and quadrature are used to approximate the posterior and perform all quadrature operations, respectively. Specifically, our algorithm uses coarse discretizations of the underlying mathematical model to investigate the parameter space and to identify areas of high posterior probability. Adaptive sparse grid algorithms are then used to place points in these areas, and ignore other areas of small posterior probability. The points are weighted Leja points. As the model discretization is coarse, the construction of the sparse grid is computationally efficient. On this sparse grid, the posterior measure can be approximated accurately with few expensive, fine model discretizations. The efficiency of the algorithm can be enhanced further by exploiting more than two discretization levels. We apply the proposed multilevel adaptive sparse Leja algorithm in numerical experiments involving elliptic inverse problems in 2D and 3D space, in which we compare it with Markov chain Monte Carlo sampling and a standard multilevel approximation.

description: We measured the vertical pressure response function of a layer of sand submitted to a localized normal force at its surface. We found that this response profile depends on the way the layer has been prepared: all profiles show a single centered peak whose width scales with the thickness of the layer, but a dense packing gives a wider peak than a loose one. We calculate the prediction of isotropic elastic theory in presence of a bottom boundary and compare it to the data. We found that the theory gives the right scaling and the correct qualitative shape, but fails to really fit the data.

description: The stability and electronic structure of a single monatomic Al wire has been studied using the ab initio pseudopotential method. The Al wire undergoes two structural rearrangements under compression, i.e., zigzag configurations at angles of $140^o$ and $60^o$. The evolution of electronic structures of the Al chain as a function of structural phase transition has been investigated. The relationship between electronic structure and geometric stability is also discussed. The 2p bands in the Al nanowire are shown to play a critical role in its stability. The effects of density functionals (GGA and LDA) on cohesive energy and bond length of Al nanostructures (dimmer, chains, and monolayers) are also examined. The link between low dimensional 0D structure (dimmer) to high dimensional 3D bulk Al is estimated. An example of optimized tip-suspended finite atomic chain is presented to bridge the gap between hypothetical infinite chains and experimental finite chains.

description: Im Zentrum der Untersuchung stehen Clanchefs und ihre Rolle bei der Integration von Nomadenstämmen unter römische Verwaltung in den Jahren der römischen Herrschat über Nordafrika von 146 v. Chr. bis ins 5. Jh. n. Chr. Ausgangspunkt der Überlegungen war, daß die ausschließlich in Personenverbänden verlaufende Organisation nomadischer Stämme für die nach dem Kriterium der Ortsfestigkeit operierende römische Verwaltung nach der Eroberung Nordafrikas 146 v. Chr. eine neuartige Herausforderung darstellte. Und es waren v. a. die Anführer dieser Stämme, deren lokale Autonomieansprüche durch die gegenüber den vorherigen Numiderkönigen intensivere Kontrolltätigkeit der Römer eingeschränkt wurden und die deshalb verstärkt rebellierten. Deshalb wurde untersucht, wie der römischen Verwaltung eine Adaption an diese andersartigen lokalen Machtstrukturen gelang. In der Tat ist die zunehmende Stabilität der römischen Herrschat ab dem 2. Jh. n. Chr. nicht unwesentlich mit der erfolgreichen Einbindung nomadischer Clanchefs verknüpt, die z. B. durch Bürgerrechtsverleihungen privilegiert wurden, während das Machtgefüge innerhalb der Stämme und damit lokale Machtstrukturen weitgehend unangetastet blieben. Dies führte zu der ambivalenten Situation, daß der schwindende Einfluss Roms in Nordafrika ab dem 5. Jh. zwar in ein erneutes Erstarken der Territorialmacht von Nomadenstämmen mündete, deren Anführer sich aber weiterhin auf Rom als Quelle ihres Prestiges beriefen.
description: The study focusses on tribal chiefs and their role in integrating nomadic tribes into the Roman administration between 146 BC and the 5th century AD when Rome ruled over North Africa. It acted on the assumption that the specific organizational structure of nomadic tribes, based primarily on personal loyalties, represented a novel challenge for the Roman administration, which was based on a sedentary structure of its subjects. Similarly, the Roman administration posed a threat to the nomadic chietains as well, because it manifested an intensified form of control in comparison with the Numidian kings who had previously ruled large parts of North Africa. Therefore, it was predominantly these chietains who initially led the fierce resistance against Rome. The study raised the question how the Roman

description: We analyse the cosmological implications of brane-antibrane systems in string-theoretic orbifold and orientifold models. In a class of realistic models, consistency conditions require branes and antibranes to be stuck at different fixed points, and so their mutual attraction generates a potential for one of the radii of the underlying torus or the 4D string dilaton. Assuming that all other moduli have been fixed by string effects, we find that this potential leads naturally to a period of cosmic inflation with the radion or dilaton field as the inflaton. The slow-roll conditions are satisfied more generically than if the branes were free to move within the space. The appearance of tachyon fields at certain points in moduli space indicates the onset of phase transitions to different non-BPS brane systems, providing ways of ending inflation and reheating the corresponding observable brane universe. In each case we find relations between the inflationary parameters and the string scale to get the correct spectrum of density perturbations. In some examples the small numbers required as inputs are no smaller than 0.01, and are the same small quantities which are required to explain the gauge hierarchy.

Axion dark matter from Higgs inflation with an intermediate $H_*$

description: In order to accommodate the QCD axion as the dark matter (DM) in a model in which the Peccei-Quinn (PQ) symmetry is broken before the end of inflation, a relatively low scale of inflation has to be invoked in order to avoid bounds from DM isocurvature fluctuations, $H_* \lesssim \mathcal{O}(10^9)\,$GeV. We construct a simple model in which the Standard Model Higgs field is non-minimally coupled to Palatini gravity and acts as the inflaton, leading to a scale of inflation $H_* \sim 10^8\,$GeV. When the energy scale at which the PQ symmetry breaks is much larger than the scale of inflation, we find that in this scenario the required axion mass for which the axion constitutes all DM is $m_0 \lesssim 0.05{\rm \,μeV}$ for a quartic Higgs self-coupling $λ_ϕ= 0.1$, which correspond to the PQ breaking scale $v_σ\gtrsim 10^{14}\,$GeV and tensor-to-scalar ratio $r \sim 10^{-12}$. Future experiments sensitive to the relevant QCD axion mass scale can therefore shed light on the physics of the Universe before the end of inflation.

The low-lying excitations of polydiacetylene

description: The Pariser-Parr-Pople Hamiltonian is used to calculate and identify the nature of the low-lying vertical transition energies of polydiacetylene. The model is solved using the density matrix renormalisation group method for a fixed acetylenic geometry for chains of up to 102 atoms. The non-linear optical properties of polydiacetylene are considered, which are determined by the third-order susceptibility. The experimental 1Bu data of Giesa and Schultz are used as the geometric model for the calculation. For short chains, the calculated E(1Bu) agrees with the experimental value, within solvation effects (ca. 0.3 eV). The charge gap is used to characterise bound and unbound states. The nBu is above the charge gap and hence a continuum state; the 1Bu, 2Ag and mAg are not and hence are bound excitons. For large chain lengths, the nBu tends towards the charge gap as expected, strongly suggesting that the nBu is the conduction band edge. The conduction band edge for PDA is agreed in the literature to be ca. 3.0 eV. Accounting for the strong polarisation effects of the medium and polaron formation gives our calculated E(nBu) ca. 3.6 eV, with an exciton binding energy of ca. 1.0 eV. The 2Ag state is found to be above the 1Bu, which does not agree with relaxed transition experimental data. However, this could be resolved by including explicit lattice relaxation in the Pariser- Parr-Pople-Peierls model. Particle-hole separation data further suggest that the 1Bu, 2Ag and mAg are bound excitons, and that the nBu is an unbound exciton.

description: We demonstrate gravity compensation for an ultracold gas of $^{87}$Rb atoms with a time-averaged optical potential. The position of a far-off-resonance beam is temporally modulated with an acousto-optic deflector to efficiently produce a potential with a linear gradient independent of the atomic magnetic sublevels. We realize compensation of the gravity sag and preparation of a degenerate gas in a trap with weak vertical confinement. Optical gravity compensation will provide the opportunity to perform experiments under microgravity in a laboratory and broaden the scope of cold atom research.

description: The initial conditions describing seed fluctuations for the formation of structure in standard cosmological models, i.e.the Harrison-Zeldovich distribution, have very characteristic ``super-homogeneous'' properties: they are statistically translation invariant, isotropic, and the variance of the mass fluctuations in a region of volume V grows slower than V. We discuss the geometrical construction of distributions of points in ${\bf R}^3$ with similar properties encountered in tiling and in statistical physics, e.g. the Gibbs distribution of a one-component system of charged particles in a uniform background (OCP). Modifications of the OCP can produce equilibrium correlations of the kind assumed in the cosmological context. We then describe how such systems can be used for the generation of initial conditions in gravitational $N$-body simulations.

description: Wie schon die meisten hellenistischen Könige zeichneten sich auch die römischen Klientelherrscher in der Zeit des frühen Prinzipat durch Stitungen und Spenden an Städte, Gemeinden und Heiligtümer außerhalb ihrer eigenen Herrschatsgebiete aus. Jedoch zeigt eine genauere Analyse der Stitungsempfänger, der Verteilung und Art ihrer Gaben, dass es bei der euergetischen Praxis der Klientelherrscher nicht um eine einfach Imitation oder Fortsetzung überlebter monarchischer Traditionen ging, sondern im Gegenteil die abhängigen Fürsten durch die auswärtigen Stitungen gezielt ihre Einbindung in das Imperium Romanum, ihre enge Beziehung zum Princeps und ihre eigene Stellung in das römische Machtgefüge kommunizierten.
description: Benefactions and donations to cities, communities and sanctuaries outside their own realms were a major instrument of public representation and propaganda for client kings in the early imperial period, emulating the model of most of their Hellenistic predecessors. However, a close analysis of the recipients of the benefactions, their geographical distribution and nature shows that the euergetism of Roman client kings was not simply an imitation or continuation of anachronistic Hellenistic royal practices. Instead, benefactions became an important instrument for the rulers to communicate their integration into the Imperium Romanum, their personal relationship with the Emperor and their own rank in the imperial hierarchy.

description: In this paper, we define and study unstable measure theoretic pressure for C^1-smooth partially hyperbolic diffeomorphisms with sub-additive potentials. For any ergodic measure, we show that this unstable metric pressure equals the corresponding unstable measure theoretic entropy plus the Lyapunov exponents with respect to the ergodic measure. On the other hand, we also define unstable topological and metric pressure in terms of the Bowen's picture and the capacity picture. We show that all these definitions of unstable metric pressure actually coincide for any ergodic measure.

description: Doppelstädte entstanden vor allem im 13. Jahrhundert, in der Zeit der Ausbreitung der Stadt mit besonderem Recht, deren wirtschaftlich aktive Bewohner eine lokale städtische Gemeinde bildeten und gleichzeitig in einem Vertragsverhältnis zu einem Herrschaftsträgerstanden. Wo sich dies nicht in einem einzigen Siedlungs- und Rechtskörper realisieren ließ, konnte eine Doppelstadt entstehen. Ein häufiger Grund war eine herrschaftliche Konkurrenzsituation am Ort. Aber auch die Ansiedlung einer größeren Gruppe von Neusiedlern, deren Integration in die bestehende Stadt Schwierigkeiten bereitete, in einer ergänzenden Neustadt zur wirtschaftlichen Stärkung des Ortes und die Lage beiderseits eines Flussübergangs konnten eine Rolle spielen.
description: Twin cities chiefly arose in the thirteenth century, during the time when cities were proliferating and had particular rights; their economically active inhabitants comprised a local urban community and at the same time were in a contractual relationship with a ruler. A twin city could arise in places where this particularity could not be realized in a singlelegal and settlement entity. One frequent reason was local competition for dominance, but a larger group of new settlers could also play a role, by settling in a complementary new city to strengthen the place economically after having trouble integrating into the existingcity, and so could a location on both sides of a river crossing.

description: A vast amount of valuable data is produced and is becoming available for analysis as a result of advancements in smart cyber-physical systems. The data comes from various sources, such as healthcare, smart homes, smart vehicles, and often includes private, potentially sensitive information that needs appropriate sanitization before being released for analysis. The incremental and fast nature of data generation in these systems necessitates scalable privacy-preserving mechanisms with high privacy and utility. However, privacy preservation often comes at the expense of data utility. We propose a new data perturbation algorithm, SEAL (Secure and Efficient data perturbation Algorithm utilizing Local differential privacy), based on Chebyshev interpolation and Laplacian noise, which provides a good balance between privacy and utility with high efficiency and scalability. Empirical comparisons with existing privacy-preserving algorithms show that SEAL excels in execution speed, scalability, accuracy, and attack resistance. SEAL provides flexibility in choosing the best possible privacy parameters, such as the amount of added noise, which can be tailored to the domain and dataset.
