description: This paper reports on the detection of optical novae in our neighbour galaxy M31 based on digitized historical Tautenburg Schmidt plates. The accurate positions of the detected novae lead to a much larger database when searching for recurrent novae in M31. We conducted a systematic search for novae on 306 digitized Tautenburg Schmidt plates covering a time span of 36 years from 1960 to 1996. From the database of both ~ 300 000 light curves and about one million detections on only one plate per colour band, nova candidates were efficiently selected by automated algorithms and subsequently individually inspected by eye. We report the detection of 84 nova candidates. We found 55 nova candidates from the automated analysis of the light curves. Among these, 22 were previously unknown, 12 were known but not identified on Tautenburg Schmidt plates before, and 21 novae had been previously discovered on Tautenburg plates. An additional 29 known novae could be confirmed by the detailed investigation of single detections. One of our newly discovered nova candidates shows a high position coincidence with a nova detected about 30 years earlier. Therefore, this object is likely to be a recurrent nova. Furthermore, we re-investigated all 41 nova candidates previously found on Tautenburg plates and confirm all but two. Positions are given for all nova candidates with a typical accuracy of ~ 0.4 arcsec. We present light curves and finding charts as online material. The analysis of the plates has shown the wealth of information still buried in old plate archives. Extrapolating from this survey, digitization of other historical M31 plate archives (e.g. from the Mount Wilson or Asiago observatories) for a systematic nova search looks very promising.

description: The societal benefit of electric vehicles depends heavily on how they interact with the electric power system. In this thesis, I investigate the impact of electric vehicles based on this interaction in order to determine the possible benefits of controlling electric vehicle charging and how they compare to other vehicle options based on optimization models of electricity systems. I estimate the cost reductions from controlled charging of electric vehicles in the New York power system both with and without a high wind penetration and with and without the need for capacity expansion. In this power system, controlled charging can reduce the generation costs associated with charging the vehicles in half, with slightly higher cost reductions in high wind scenarios. I also estimate the cost reductions along with the changes in carbon and criteria air pollutant emissions due to controlled charging in the PJM power system. I examine both current and future grid scenarios, several plug-in vehicles types, and a high wind penetration scenario. Again I find that controlled charging can significantly reduce the costs of charging the vehicles, on the order of 30% of the generation costs to meet the charging demand. However, the environmental and health damages from the emissions cause total social costs to be higher with controlled charging in most cases. Finally, using the charging emissions from PJM, I evaluate the lifecycle emissions of plug-in, hybrid, and conventional vehicles in this region to determine which has lower environmental and health damages. I find that given the representative vehicles studied, plug-in electric vehicles have higher lifecycle damages than hybrids in PJM in 2010 but have lower lifecycle damages in a forecasted 2018 PJM power system.

We derive the determinant formula for the scalar products by applying the Izergin-Korepin technique developed by Wheeler to investigate the scalar products of integrable lattice models. By combining the determinant formula for the scalar products with the recently-developed Izergin-Korepin technique to analyze the wavefunctions, we derive a Cauchy formula for elliptic Schur functions.

description: Kazuo Kondo (1911-2001) was Chair of the Department of Mathematical Engineering at the University of Tokyo, Japan. Over a period of 50 years, he and a few colleagues wrote and published a voluminous series of papers and monographs on the applications of analytical geometry within a diverse range of subjects in the natural sciences. Inspired by Otto Fischer's attempt at a quaternionic unified theory in the late 1950's he adopted the mathematics of the revered Akitsugu Kawaguchi to produce his own speculative unified theory. The theory appears to successfully apply Kawaguchi's mathematics to the full range of natural phenomena, from the structure of fundamental particles to the geometry of living beings. The theories are testable and falsifiable. Kondo and his theories are now almost completely unknown and this paper serves as the barest introduction to his work

description: Abstract:  The selection of a portfolio encounters several extremely complex situations. From among them, it has to be highlighted, due to its difficulty and transcendence, the Financial Assets selection when interrelations (positive and/or negative) occur among the expected profitabilities of each one of them. The tools traditionally used have tried to approach it by simplifying reality and, therefore, the obtained results are not fully satisfactory. This situation has encouraged the authors to questioning whether better solutions can be reached by applying the so called Intelligent Technologies. Thus, one of the available tools is the one constituted by Genetic Algorithms, due to its utility when offering solutions to complex optimization problems. Furthermore, by using the Fuzzy Sets Theory. we intend to obtain a closer representation for the uncertainty that characterises Financial Market. This way, it is intended to outline an approach to solve Financial Assets selection problems for a portfolio in a non-linear and uncertainty environment, by applying a Fuzzy Genetic Algorithm to optimize the investment profitability.

description: The recent LEP data for gauge coupling constants constrain many grand unified models. In this paper, we study several possibilities for unification of gauge coupling constants. Without an intermediate mass scale, the minimal supersymmetric standard model is the only possibility. For one intermediate mass scale, it is possible to have many routes toward grand unification: $SO(10)\rightarrow SU(3)_c\times SU(2)_L\times SU(2)_R\times U(1) , SU(7), SU(8)$, etc. We present also simple relations for the possibility of unification.

Universal Features of BPS Strings in Six-dimensional SCFTs

Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In theories with extended supersymmetry the protected observables of UV superconformal fixed points are found in a number of contexts to be encoded in the BPS solitons along an IR Coulomb-like phase. For six-dimensional SCFTs such a role is played by the BPS strings on the tensorial Coulomb branch. In this paper we develop a uniform description of the worldsheet theories of a BPS string for rank-one 6d SCFTs. These strings are the basic constituents of the BPS string spectrum of arbitrary rank six-dimensional models, which they generate by forming bound states. Motivated by geometric engineering in F-theory, we describe the worldsheet theories of the BPS strings in terms of topologically twisted 4d $\mathcal{N}=2$ theories in the presence of $1/2$-BPS 2d $(0,4)$ defects. As the superconformal point of a 6d theory with gauge group $G$ is approached, the resulting worldsheet theory flows to an $\mathcal{N}=(0,4)$ NLSM with target the moduli space of one $G$ instanton, together with a nontrivial left moving bundle characterized by the matter content of the six-dimensional model. We compute the anomaly polynomial and central charges of the NLSM, and argue that the 6d flavor symmetry $F$ is realized as a current algebra on the string, whose level we compute. We find evidence that for generic theories the $G$ dependence is captured at the level of the elliptic genus by characters of an affine Kac-Moody algebra at negative level, which we interpret as a subsector of the chiral algebra of the BPS string worldsheet theory. We also find evidence for a spectral flow relating the R-R and NS-R elliptic genera. These properties of the string CFTs lead to constraints on their spectra, which in combination with modularity allow us to determine the elliptic genera of a vast number of string CFTs, leading also to novel results for 6d and 5d instanton partition functions.

We calculate the ballistic phonon conductance G for membranes using elasticity theory, considering the transition from three to two dimensions. We discuss the temperature and thickness dependence and especially concentrate on the issue of material parameters. For all membrane thicknesses, the best conductors have, counter-intuitively, the lowest speed of sound.

description: In the holographic correspondence, subregion duality posits that knowledge of the mixed state of a finite spacelike region of the boundary theory allows full reconstruction of a specific region of the bulk, known as the entanglement wedge. This statement has been proven for local bulk operators. In this paper, specializing first for simplicity to a Rindler wedge of AdS$_3$, we find that generic curves within the wedge are in fact not fully reconstructible with entanglement entropies in the corresponding boundary region, even after using the most general variant of hole-ography, which was recently shown to suffice for reconstruction of arbitrary spacelike curves in the Poincare patch. This limitation is an analog of the familiar phenomenon of entanglement shadows, which we call 'entanglement shade'. We overcome it by showing that the information about the nonreconstructible curve segments is encoded in a slight generalization of the concept of entanglement of purification, whose holographic dual has been discussed very recently. We introduce the notion of 'differential purification', and demonstrate that, in combination with differential entropy, it enables the complete reconstruction of all spacelike curves within an arbitrary entanglement wedge in any 3-dimensional bulk geometry.

description: We calculate leading long-distance noncommutative corrections to the classical Schwarzschild black hole which is sourced by a massive noncommutative scalar field. The energy-momentum tensor is taken up to ${\cal O}(\ell^4)$ in noncommutative parameter, and is treated in semiclassical (tree level) approximation. These noncommutative corrections can dominate classical post-post-Newtonian corrections providing $\ell > 1/M_P$, however, they are still too small to be observable in present-day experiments.

description: Recently, Madsen has argued that relativistic decays of massive neutrinos into lighter fermions and bosons may lead, via thermalization, to the formation of a Bose condensate. If correct, this could generate mixed hot and cold dark matter, with important consequences for structure formation. From a detailed study of such decays, we arrive at substantially different conclusions; for a wide range of masses and decay times, we find that stimulated emission of bosons dominates the decay. This phenomenon can best be described as a neutrino laser, pumped by the QCD phase transition. We discuss the implications for structure formation and the dark-matter problem.

description: This presentation explores the complexities of measuring the impact of use vs. reuse among cultural heritage and knowledge organizations (including but not limited to museums, libraries, archives, data repositories, and historical societies). It will provide an overview of the project team's evolving definitions for use and reuse, informed by their work with the Measuring Reuse project. These definitions help delineate the differences between reuse and use, thus setting the stage to help information professionals determine which use cases should be considered use or reuse and developing more detailed and relevant assessments of the impact of digital collections. The speakers will apply the new definitions to specific use cases to show their utility and value and suggest how these efforts will lead to more informed assessment methods of digital library materials.
The volume densities of GMCs in M81

description: HI features near young star clusters in M81 are identified as the photodissociated surfaces of Giant Molecular Clouds (GMCs) from which the young stars have recently formed. The HI column densities of these features show a weak trend, from undetectable values inside R = 3.7 kpc and increasing rapidly to values around 3 x 10^21 cm^-2 near R ~ 7.5 kpc. This trend is similar to that of the radially-averaged HI distribution in this galaxy, and implies a constant area covering factor of ~ 0.21 for GMCs throughout M81. The incident UV fluxes G0 of our sample of candidate PDRs decrease radially. A simple equilibrium model of the photodissociation-reformation process connects the observed values of the incident UV flux, the HI column density, and the relative dust content, permitting an independent estimate to be made of the total gas density in the GMC. Within the GMC this gas will be predominantly molecular hydrogen. Volume densities of 1 < n < 200 cm^-3 are derived, with a geometric mean of 17 cm^-3. These values are similar to the densities of GMCs in the Galaxy, but somewhat lower than those found earlier for M101 with similar methods. Low values of molecular density in the GMCs of M81 will result in low levels of collisional excitation of the CO(1-0) transition, and are consistent with the very low surface brightness of CO(1-0) emission observed in the disk of M81.

description: Motivated by recent experiments at LEP ($Z \to l^+l^-γγ$, with $M_{γγ} \simeq 59 GeV$), we examine the possibility that such events are explained by a Bjorken process with a resonant Higgs ($M_{h^o} \simeq 59 GeV$) decaying to $γγ$. Our model is an N-doublet-Higgs model without CP-violation. Under the simplifying assumption that $(N-k)$ doublets ($k \geq 1$) decouple from the fermion sector, we could explain the observed events if: i) $(N-1) \geq 2$ and ii) the masses of the corresponding $(N-1)$ neutral scalars are either completely or almost degenerate, i.e. the decay $Z \to l^+l^- γγ$ proceeds now via several overlapping resonances.

description: The advent of the nanoscale integrated circuit (IC) technology makes high performance analog and RF circuit increasingly susceptible to large-scale process variations. Process variations, including inter-die variations and local mismatches, significantly impact the parametric yield of analog/RF circuit, and must be properly handled at all levels of design hierarchy. Traditional approaches based on over-design are not sufficient to maintain high parametric yield, due to the large-scale process variations and aggressive design specifications at advanced technology nodes. In this context, the self-healing circuit has emerged as promising methodology to address the variability issue. In this thesis, we propose efficient pre-silicon validation and post-silicon tuning techniques, which are essential for the practical usage of self-healing methodology. One important problem in self-healing methodology is to efficiently and accurately predict the parametric yield in pre-silicon. The main challenge of this problem is caused by multiple circuit states related to tuning knobs. Given that these circuit states closely interact with process variations, they must be properly modeled in order to accurately estimate the parametric yield. Towards this goal, we develop an efficient performance modeling algorithm, referred to Correlated Bayesian Model Fusion (C-BMF) that explores the correlation between circuit states. Next, based on the performance model, the self-healing behavior and the parametric yield can be efficiently and accurately predicted. Another important problem in self-healing circuit is to efficiently perform post-silicon tuning. Towards this goal, indirect performance sensing methodology has recently attracted great attention. In the indirect performance sensing paradigm, the performance of interest (PoI) is not directly measured by on-chip sensor, but is instead accurately predicted from an indirect sensor model. Such indirect sensor model takes a set of other performances as inputs, which are referred to as the performances of measurements (PoMs). The PoMs are selected such that they are highly correlated with PoI and are easy to measure. Due to the process shift associated with manufacturing lines, the indirect sensor model must be calibrated from time to time. For the purpose of reducing the model calibration cost, we propose a Bayesian Model Fusion (BMF) algorithm that reuses the information collected in early stage of manufacturing. We further extend BMF to a Co-learning Bayesian Model Fusion (CL-BMF) algorithm that incorporates not only the early stage information, but also the current stage information that was not considered in the original modeling problem.

description: Here we report the observation of Fermi surface (FS) pockets via the Shubnikov de Haas effect in Na$_x$CoO$_2$ for $x = 0.71$ and 0.84, respectively. Our observations indicate that the FS expected for each compound intersects their corresponding Brillouin zones, as defined by the previously reported superlattice structures, leading to small reconstructed FS pockets, but only if a precise number of holes per unit cell is \emph{localized}. For $0.71 \leq x < 0.75$ the coexistence of itinerant carriers and localized $S =1/2$ spins on a paramagnetic triangular superlattice leads at low temperatures to the observation of a deviation from standard Fermi-liquid behavior in the electrical transport and heat capacity properties, suggesting the formation of some kind of quantum spin-liquid ground state.

description: Despite being controversial, research metrics are becoming a key component of research evaluation processes globally. Nevertheless, accessing research metrics to support these processes in a timely manner is not a straightforward task, as it requires either having access to expensive commercial solutions such as Elsevier SciVal or Clarivate Analytics' InCites, or having substantial knowledge of existing APIs and data sources as well as the ability and skills needed to analyse large amounts of raw scholarly data in-house. This is especially the case on a department or institutional level where large amounts of data have to be aggregated prior to analysis. To alleviate this problem we have designed and prototyped CORE Analytics Dashboard – a tool for analytical evaluation of research outputs of universities. The aim of the CORE Analytics Dashboard is to help universities analyse their performance using a variety of metrics captured from openly available data sources, including citation counts and social media metrics, and to help them compare their performance with other institutions. This paper presents the motivation behind developing this dashboard and its main features.

description: We give a geometrical set up for the semiclassical approximation to euclidean field theories having families of minima (instantons) parametrized by suitable moduli spaces ${\cal M}$. The standard examples are of course Yang-Mills theory and non-linear $σ$-models. The relevant space here is a family of measure spaces $\tilde {\cal N} \ra {\cal M}$, with standard fibre a distribution space, given by a suitable extension of the normal bundle to ${\cal M}$ in the space of smooth fields. Over $\tilde {\cal N}$ there is a probability measure $dμ$ given by the twisted product of the (normalized) volume element on ${\cal M}$ and the family of gaussian measures with covariance given by the tree propagator $C_ϕ$ in the background of an instanton $ϕ\in {\cal M}$. The space of ``observables", i.e. measurable functions on ($\tilde {\cal N}, \, dμ$), is studied and it is shown to contain a topological sector, corresponding to the intersection theory on ${\cal M}$. The expectation value of these topological ``observables" does not depend on the covariance; it is therefore exact at all orders in perturbation theory and can moreover be computed in the topological regime by setting the covariance to zero.

description: State estimation and tracking (also known as filtering) is an integral part of any system performing inference in a partially observable environment, whether it is a robot that is gauging an environment through noisy sensors or a natural language processing system that is trying to model a sequence of characters without full knowledge of the syntactic or semantic state of the text. In this work, we develop a framework for constructing state estimators. The framework consists of a model class, referred to as predictive state models, and a learning algorithm, referred to as two-stage regression. Our framework is based on two key concepts: (1) predictive state: where our belief about the latent state of the environment is represented as a prediction of future observation features and (2) instrumental regression: where features of previous observations are used to remove sampling noise from future observation statistics, allowing for unbiased estimation of system dynamics. These two concepts allow us to develop efficient and tractable learning methods that reduce the unsupervised problem of learning an environment model to a supervised regression problem: first, a regressor is used to remove noise from future observation statistics. Then another regressor uses the denoised observation features to estimate the dynamics of the environment. We show that our proposed framework enjoys a number of theoretical and practical advantages over existing methods, and we demonstrate its efficacy in a prediction setting, where the task is to predict future observations, as well as a control setting, where the task is to optimize a control policy via reinforcement learning.

description: On the basis of first-principle calculation using density functional theory, we systematically investigate the vibrational properties and thermal properties of two-dimensional honeycomb lattices of graphene, silicene and black phosphorene. We focus on the similarities and differences of their properties and try to understand them from their lattice structures. We illustrate that, a phonon band gap develops in silicene and black phosphorene which reduce effectively the phonon thermal conductivity. All the systems (graphene, silicene and black phosphorene) have positive frequencies which ensure their structural stability. Also, we found that the specific heat, entropy and free energy for all the systems increases rapidly at very low temperature and specific heat (Cv) become constant at higher temperature.

description: In [P. Kanti, B. Kleihaus, J. Kunz, Phys. Rev. Lett. 107, 271101 (2011)] it was shown that the four-dimensional Einstein-dilaton-Gauss-Bonnet theory allows for wormholes without introducing any exotic matter. The numerical solution for the wormhole was obtained there and it was claimed that this solution is gravitationally stable against radial perturbations, what, by now, would mean the only known theoretical possibility for existence of an apparently stable, four-dimensional and asymptotically flat wormhole without exotic matter. Here, more detailed analysis of perturbations shows that the Kanti-Kleihaus-Kunz wormhole is unstable against small perturbations for any values of its parameters. The exponential growth appears in the time domain after a long period of damped oscillations, in the same way as it takes place in the case of unstable higher-dimensional black holes in the Einstein-Gauss-Bonnet theory. The instability is driven by the purely imaginary mode, which is nonperturbative in the Gauss-Bonnet coupling$α$.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Green and gold are artificial distinctions, mainly driven by the technical and business separation between publishing platforms and institutional and thematic repositories operated by research institutions or research communities. Building on two efforts that were presented last year at Open Repositories in 2018, (1) Next Generation Repositories functionalities and (2) prospects for greater integration between repositories and journal publishing platforms, we have developed a conceptual model for publishing overlay services on top of distributed repository platforms. The model removes the green and gold dichotomy by providing a system that integrates publishing capabilities with repository capabilities, thereby combining the strength of the two worlds, while building out an integrative and interoperable infrastructure for scholarly communication.
Closing the gap – connection points between DMPs and repositories

description: This proposal is for a 3 hour workshop session to discuss the potential connection points between Data Management Plans and repository platforms. DMPs capture a lot of useful information that could assist repositories in capacity planning and improving deposit workflows. At the IDCC conference in 2017, we ran a workshop that gathered requirements based around a number of use cases, including those of the repository community. [1] In the White Paper that resulted, we highlighted a number of potential avenues for exploration. In the intervening period, a series of activities have taken place internationally. The California Digital Library has an NSF Eager grant in which they have been collaborating with data centres. [3] Meanwhile DCC is developing export features to common repository and journal platforms. Within the Research Data Alliance, two Working Groups are developing Common Standards for DMPs [4] to facilitate information exchange and addressing use cases for 'exposing DMPs' – specifically what information can be shared and how, when and by whom can it be used. [5] The workshop will provide an update on recent activities and engage with the OR community to develop work further. [Refs] ran out of space!

description: We perform the first global QCD analysis of parton distribution functions (PDFs) in the pion, combining $πA$ Drell-Yan data with leading neutron electroproduction from HERA within a Monte Carlo approach based on nested sampling. Inclusion of the HERA data allows the pion PDFs to be determined down to much lower values of $x$, with relatively weak model dependence from uncertainties in the chiral splitting function. The combined analysis reveals that gluons carry a significantly higher pion momentum fraction, $\sim 30\%$, than that inferred from Drell-Yan data alone, with sea quarks carrying a somewhat smaller fraction, $\sim 15\%$, at the input scale. Within the same effective theory framework, the chiral splitting function and pion PDFs can be used to describe the $\bar d-\bar u$ asymmetry in the proton.

description: We investigate the influence of an interaction between dark energy and dark matter upon the dynamics of galaxy clusters. We obtain the general Layser-Irvine equation in the presence of interactions, and find how, in that case, the virial theorem stands corrected. Using optical, X-ray and weak lensing data from 33 relaxed galaxy clusters, we put constraints on the strength of the coupling in the dark sector. We find that this coupling is small but positive, indicating that dark energy can be decaying into dark matter.

description: Recent years have seen an uptick in master boot record (MBR) based rootkits that load before the Windows operating system and subvert the operating system’s own procedures. As such, MBR rootkits are difficult to counter with operating system-based antivirus software that runs at the same privilege-level as the rookits. Hypervisors operate at a higher privilege level than the guests they manage, creating a high-ground position in the host. This high-ground position can be exploited to perform security checks on the virtual machine guests where the checking software is isolated from guest-based viruses. The efficient introspection system described in this thesis targets existing virtualized systems to improve security with real-time, concurrent memory introspection capabilities. Efficient introspection decouples memory introspection from virtual machine guest execution, establishes coherent and consistent memory views between the host and running guest, while maintaining normal guest operation. Existing introspection systems have provided one or two of these properties but not all three at once. This thesis presents a new concurrent-computing approach – high-performance memory snapshotting – to accelerating hypervisor based introspection of virtual machine guest memory that combines all three elements to improve performance and security. Memory snapshots create a coherent and consistent memory view of the guest that can be shared with the independently running introspection application. Three memory snapshotting mechanisms are presented and evaluated for their impact on normal guest operation. Existing introspection systems and security protection techniques that were previously dismissed as too slow are now be enabled by efficient introspection. This thesis explains why existing introspection systems are inadequate, describes how existing system performance can be improved, evaluates an efficient introspection prototype on both applications and microbenchmarks, and discusses two potential security applications that are enabled by efficient introspection. These applications point to efficient introspection’s utility for supporting useful security applications.

description: We have studied the scalar field as well as the fermonic field perturbations in the background of the massless BTZ black holes. Comparing with the perturbation results in the generic nonrotating BTZ black hole background, we found that the massless BTZ hole contains only normal modes in the perturbations. We argued that this special property reflects that the massless BTZ black hole is a different phase from that of the generic nonrotating BTZ hole.
