description: The conformal anomaly induced sector of four-dimensional quantum gravity (infrared quantum gravity) ---which has been introduced by Antoniadis and Mottola--- is here studied on a curved fiducial background. The one-loop effective potential for the effective conformal factor theory is calculated with accuracy, including terms linear in the curvature. It is proven that a curvature induced phase transition can actually take place. An estimation of the critical curvature for different choices of the parameters of the theory is given.

description: To probe CP violation in the leptonic sector using GeV energy neutrino beams in current and future experiments using argon detectors, precise models of the complex underlying neutrino and antineutrino interactions are needed. The E12-14-012 experiment at Jefferson Lab Hall A was designed to perform a combined analysis of inclusive and exclusive electron scatterings on both argon ($N = 22$) and titanium ($Z = 22$) nuclei using GeV energy electron beams. The measurement on titanium nucleus provides essential information to understand the neutrino scattering on argon, large contribution to which comes from scattering off neutrons. Here we report the first experimental study of electron-titanium scattering as double differential cross section at beam energy $E=2.222$ GeV and electron scattering angle $θ= 15.541$ deg, measured over a broad range of energy transfer, spanning the kinematical regions in which quasielastic scattering and delta production are the dominant reaction mechanisms. The data provide valuable new information needed to develop accurate theoretical models of the electromagnetic and weak cross sections of these complex nuclei in the kinematic regime of interest to neutrino experiments.

description: We present the first high spatial resolution near-infrared direct and polarimetric observations of Parsamian 21, obtained with the VLT/NACO instrument. We complemented these measurements with archival infrared observations, such as HST/WFPC2 imaging, HST/NICMOS polarimetry, Spitzer IRAC and MIPS photometry, Spitzer IRS spectroscopy as well as ISO photometry. Our main conclusions are the following: (1) we argue that Parsamian 21 is probably an FU Orionis-type object; (2) Parsamian 21 is not associated with any rich cluster of young stars; (3) our measurements reveal a circumstellar envelope, a polar cavity and an edge-on disc; the disc seems to be geometrically flat and extends from approximately 48 to 360 AU from the star; (4) the SED can be reproduced with a simple model of a circumstellar disc and an envelope; (5) within the framework of an evolutionary sequence of FUors proposed by Green et al. (2006) and Quanz et al. (2007), Parsamian 21 can be classified as an intermediate-aged object.

description: We study various geometrical aspects of the propagation of particles obeying fractional statistics in the physical setting of the quantum Hall system. We find a discrete set of zeros for the two-particle kernel in the lowest Landau level; these arise from a combination of a two-particle Aharonov-Bohm effect and the exchange phase related to fractional statistics. The kernel also shows short distance exclusion statistics, for instance, in a power law behavior as a function of initial and final positions of the particles. We employ the one-particle kernel to compute impurity-mediated tunneling amplitudes between different edges of a finite-sized quantum Hall system and and find that they vanishes for certain strengths and locations of the impurity scattering potentials. We show that even in the absence of scattering, the correlation functions between different edges exhibits unusual features for a narrow enough Hall bar.

description: The explosive growth of multimedia content on the Internet is revolutionizing the way of multimedia security and copyright management. Unfortunately, the two major technological solu-tions in the past decade, namely encryption and watermarking, are ill-equipped to deal with the change. This article introduces the third solution, i.e., Content-based Multimedia Identification (CBMI). The key idea is to automatically generate a new descriptor from the content, called mediaprint, as the identifier of that media item. Compared with the active protection (i.e., encryption) and authen-tication (i.e., watermarking) approaches, CBMI of-fers a passive but reproducible and reliable ap-proach to manage rights of the digital content.

description: The discovery of a repeating fast radio burst has led to the first precise localization, an association with a dwarf galaxy, and the identification of a coincident persistent radio source. However, further localizations are required to determine the nature of FRBs, the sources powering them, and the possibility of multiple populations. Here we investigate the use of associated persistent radio sources to establish FRB counterparts, taking into account the localization area and the persistent source flux density. Due to the lower areal number density of radio sources compared to faint optical sources, robust associations can be achieved for less precise localizations as compared to direct optical host galaxy associations. For generally larger localizations which preclude robust associations, the number of candidate hosts can be reduced based on the ratio of radio-to-optical brightness. We find that confident associations with $\sim 0.01-$1 mJy sources, comparable to the luminosity of the persistent source associated with FRB 121102 over the redshift range $z \approx 0.1 - 1$, require FRB localizations of $\lesssim 20''$. In the absence of a robust association, constraints can be placed on the luminosity of an associated radio source as a function of localization and DM. For DM $\approx 1000 \rm \ pc \ cm^{-3}$, an upper limit comparable to the luminosity of the FRB 121102 persistent source can be placed if the localization is $\lesssim 10''$. We apply our analysis to the case of the ASKAP FRB 170107, using optical and radio observations of the localization region. We identify two candidate hosts based on a ratio of radio-to-optical brightness of $\gtrsim 100$. We find that if one of these is associated with FRB 170107, the resulting radio luminosity ($1 \times 10^{29} - 4 \times 10^{30} \ \rm erg \ s^{-1} \ Hz^{-1}$) is comparable to the luminosity of the FRB 121102 persistent source.

description: Using linear response theory within the Random Phase Approximation, we investigate the propagation of sound in a uniform two dimensional (2D) Bose gas in the collisionless regime. We show that the sudden removal of a static density perturbation produces a damped oscillatory behavior revealing that sound can propagate also in the absence of collisions, due to mean-field interaction effects. Our analysis points out the crucial role played by Landau damping. We support our predictions by performing numerical simulations with the stochastic (projected) Gross-Pitaevskii equation. The results are consistent with the recent experimental observation of sound in a weakly interacting 2D Bose gas both below and above the superfluid Berezinskii-Kosterlitz-Thouless transition.

The density function of expenditure exhibits a fat tail that follows a power law. We observe the Pareto principle where both the top 25% and 2% of the customers account for 80% and 25% of the store's sales, respectively. Using the Lorenz curve, the Gini coefficient is estimated to be 0.70; this implies a strong economic inequality.

Loss of superfluidity in the Bose-Einstein condensate in an optical lattice with cubic and quintic nonlinearity

description: In a one-dimensional shallow optical lattice, in the presence of both cubic and quintic nonlinearity, a superfluid density wave is identified in a Bose-Einstein condensate. Interestingly, it ceases to exist when only one of these interactions is operative. We predict the loss of superfluidity through a classical dynamical phase transition, where modulational instability leads to the loss of phase coherence. In a certain parameter domain, the competition between lattice potential and the interactions is shown to give rise to a stripe phase, where atoms are confined in finite domains. In a pure two-body case, apart from the known superfluid and insulating phases, a density wave insulating phase is found to exist, possessing two frequency modulations commensurate with the lattice potential.

Proposed Solutions to Problems with Academic Copyright

description: Legislated to promote the progress of science and art, copyright in the academy appears to be broken. High prices, restricted access and copyright term extensions that exceed the market viability of academic work limit readership and thus impede rather than promote innovation and the public good. At least four approaches to solving the problem have been articulated. Three of the four approaches work within the parameters of copyright law. Steven Shavell suggests adding a legislative exception that would abolish copyright to academic work. Robert Kasunic recommends broadening examination and application of the second factor - the nature of the copyrighted work - in fair use assessments to force focus onto the incentivizing purpose of copyright for the original authors rather than the market economics of secondary copyright owners. The open access movement promotes author and sponsor education and retention of the copyrights necessary to provide free, legal access to academic work on the Internet. Google, the Authors Guild and the Association of American Publishers seek to solve copyright monopoly problems with a commercial monopoly that would be established by judicial decision, sidestepping existing laws and the legislative process altogether. This presentation will provide a brief comparative analysis of the four approaches to solving copyright problems in the academy. The analysis will explore their driving assumptions, range of application and fit with the gift culture and needs of the academy, exposing barriers to their success. An aggressive push for open access remains the only option that maintains faculty honor, propriety, autonomy and control.

description: Extremal black holes are studied in a two dimensional model motivated by a dimensional reduction from four dimensions. Their quantum corrected geometry is calculated semiclassically and a mild singularity is shown to appear at the horizon. Extensions of the geometry past the horizon are not unique but there are continuations free from malevolent singularities. A few comments are made about the relevance of these results to four dimensions and to the study of black hole entropy and information loss.

description: We evaluate the no-boundary path integral exactly in a Bianchi IX minisuperspace with two scale factors. In this model the no-boundary proposal can be implemented by requiring one scale factor to be zero initially together with a judiciously chosen regularity condition on the momentum conjugate to the second scale factor. Taking into account the non-linear backreaction of the perturbations we recover the predictions of the original semiclassical no-boundary proposal. In particular we find that large perturbations are strongly damped, consistent with vacuum state wave functions.

description: We study the effective degrees of freedom of the lasso in the framework of Stein's unbiased risk estimation (SURE). We show that the number of nonzero coefficients is an unbiased estimate for the degrees of freedom of the lasso--a conclusion that requires no special assumption on the predictors. In addition, the unbiased estimator is shown to be asymptotically consistent. With these results on hand, various model selection criteria--$C_p$, AIC and BIC--are available, which, along with the LARS algorithm, provide a principled and efficient approach to obtaining the optimal lasso fit with the computational effort of a single ordinary least-squares fit.

description: We investigate one-particle semi-inclusive processes in lepton-hadron scattering. In unpolarized scattering order $Q^{-1}$ corrections appear only when transverse momenta are detected. We consider the twist two and three matrix elements and calculate the semi-inclusive structure functions in terms of quark correlation functions. We find that at twist three level not only the standard quark distribution and fragmentation function contribute, but also two new transverse "profile functions". We demonstrate explicit gauge invariance of the hadronic tensor at the twist three level. The results of our approach are used to calculate expressions for some cross sections for semi-inclusive processes.

description: Section 1 of the present paper describes the main policy instruments characterising the Common Agricultural Policy (CAP) and Italy's position within the EEC as far as the agricultural sector is concerned. The figures presented show an overall and substantial weakness in Italian agriculture. Italy's chances of reducing its foreign trade deficit in agricultural commodities are certainly weakened by concern at Community level about discouraging agricultural production in order to deal with increasing surpluses and the growing pressure of agricultural expenses on the Community budget. Such concern is reflected in the policy initiatives with which policy makers have attempted to restore a certain degree of inelasticity in the agricultural product demand function as well as in the recently introduced set-aside programme. As far as the relationship between CAP and the environment is concerned (section 2), it is emphasised that at the time when CAP goals were established environmental issues were extremely marginal, and it is only very recently that this view has begun to change. The emphasis recently placed in official statements on the need for reorienting agricultural policy in order to improve the allocation of natural resources within the sector is to be welcomed. However, there is a risk that the emphasis placed on environmental issues is merely a 'cosmetic' for covering over other objectives, and in any case one can justifiably wonder whether European policymakers have yet learned from past experience about the risks of ineffectiveness and inefficiency inherent in an approach which applies a limited number of policy instruments in order to deal with a plurality of objectives. In revising the CAP, agricultural policy-makers should be aware that they face a number of 'second-best theorem' problems. Caution in designing new policy instruments is called for by the simultaneous presence of different types of distortions, suggesting that there is no single panacea for improving resource allocation within European agriculture, and that there is a need for articulated policy revision, taking account of the differences in agricultural structures and environmental conditions in Europe.
Theory of metal-insulator transitions in graphite under high magnetic field

description: Graphite under high magnetic field exhibits consecutive metal-insulator (MI) transitions as well as re-entrant insulator-metal (IM) transition in the quasi-quantum limit at low temperature. In this paper, we identify the low-$T$ insulating phases as excitonic insulators with spin nematic orderings. We first point out that graphite under the relevant field regime is in the charge neutrality region, where electron and hole densities compensate each other. Based on this observation, we introduce interacting electron models with electron pocket(s) and hole pocket(s) and enumerate possible umklapp scattering processes allowed under the charge neutrality. Employing effective boson theories for the electron models and renormalization group (RG) analyses for the boson theories, we show that there exist critical interaction strengths above which the umklapp processes become relevant and the system enter excitonic insulator phases with long-range order of spin superconducting phase fields ("spin nematic excitonic insulator"). We argue that, when a pair of electron and hole pockets get smaller in size, a quantum fluctuation of the spin superconducting phase becomes larger and destabilizes the excitonic insulator phases, resulting in the re-entrant IM transitions. We also show that an odd-parity excitonic pairing between the electron and hole pockets reconstruct surface chiral Fermi arc states of electron and hole into a 2-dimensional helical surface state with a gapless Dirac cone. We discuss field- and temperature-dependences of in-plane resistance by surface transports via these surface states.

description: We discuss the possibility of accurately estimating the source number density of ultra-high-energy cosmic rays (UHECRs) using small-scale anisotropy in their arrival distribution. The arrival distribution has information on their source and source distribution. We calculate the propagation of UHE protons in a structured extragalactic magnetic field (EGMF) and simulate their arrival distribution at the Earth using our previously developed method. The source number density that can best reproduce observational results by Akeno Giant Air Shower Array is estimated at about $10^{-5} {\rm Mpc}^{-3}$ in a simple source model. Despite having large uncertainties of about one order of magnitude, due to small number of observed events in current status, we find that more detection of UHECRs in the Auger era can sufficiently decrease this so that the source number density can be more robustly estimated. 200 event observation above $4 \times 10^{19} {\rm eV}$ in a hemisphere can discriminate between $10^{-5}$ and $10^{-6} {\rm Mpc}^{-3}$. Number of events to discriminate between $10^{-4}$ and $10^{-5} {\rm Mpc}^{-3}$ is dependent on EGMF strength. We also discuss the same in another source model in this paper.

description: Aufgrund der stetig wachsenden Anforderungen an die Netzinfrastruktur, stellt der Einsatz von leistungsstarken Switches und Netzwerkkarten, die Datenraten von bis zu 100 Gbit/s bereitstellen, eine wesentliche Bedeutung für Rechenzentren dar. Weil jedoch die Systemsoftware von Servern nicht für solch hohe E/A-Geschwindigkeiten konzipiert wurde, ist es kaum möglich das Leistungspotential dieser Netzwerkgeräte vollumfänglich auszuschöpfen. Neben der Übergabe von Anwendungslogik an den Gerätetreiber (z.B. mittels eBPF) oder dem direkten Speichertransfer (z.B. via RDMA) sind Kernel-Bypass-Lösungen ein leistungsstarker Optimierungsansatz, um dem hohen Datenaufgebot von heutigen Netzwerkschnittstellen standzuhalten. Das von Intel entwickelte Framework DPDK hat sich dabei in verschiedenen Benchmarks als performanteste Kernel-Bypass-Lösungen herausgestellt. Diese Arbeit wird deshalb schwerpunktmäßig die Datenstrukturen und Mechanismen untersuchen, welche den Leistungsunterschied von DPDK gegenüber vergleichbaren Frameworks möglich machen.

description: In this letter we present constant solutions to the tetrahedron equations proposed by Zamolodchikov. In general, from a given solution of the Yang-Baxter equation there are two ways to construct solutions to the tetrahedron equation. There are also other kinds of solutions. We present some two-dimensional solutions that were obtained by directly solving the equations using either an upper triangular or Zamolodchikov's ansatz.

description: Bosonization techniques are important nonperturbative tools in quantum field theory. In three dimensions they possess interesting connections to topologically ordered systems and ultimately have driven the observation of an impressive web of dualities. In this work, we use the quantum wires formalism to show how the fermion-boson mapping relating the low-energy regime of the massive Thirring model in three spacetime dimensions with the Maxwell-Chern-Simons model can be obtained from the exact bosonization in two dimensions.

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.

Strongly Interacting W's and Z's and the Existence of a Heavy Fourth Generation of Fermions

description: By employing the dictum that axiomatic principles are devoid of predictive power, we find that the elastic unitarity constraint, applied to strong W$_L$W$_L$ scattering, does not alter the assumed spectrum of intermediate states. We consider intermediate states involving a heavy Higgs and heavy fermions of a hypothetical fourth generation doublet. In contrast to recent studies, we find no p-wave resonance, and therefore no violation of the S parameter upper bound. We conclude that the elastic unitarity constraint sheds no light on the existence of a heavy fourth generation.

description: We study quantum phase transitions (QPTs) associated with splitting nodal Fermi points, motivated by topological phase transitions between Dirac and Weyl semi-metals. A Dirac point in Dirac semi-metals may be split into two Weyl points by breaking a lattice symmetry or time reversal symmetry, and the Lifshitz transition is commonly used to describe the phase transitions. Here, we show that the Lifshitz description is fundamentally incorrect in QPTs with splitting nodal Fermi points. We argue that correlations between fermions, order parameter, and the long range Coulomb interaction { must} be incorporated from the beginning. One of the most striking correlation effects we find is {\it infinite anisotropy} of physical quantities, which cannot appear in a Lifshitz transition. By using the standard renormalization group (RG) method, two types of infinitely anisotropic quantum criticalities are found in three spatial dimensions varying with the number of the Dirac points ($N_f$). For $N_f = 1$, the ratio of the fermion velocity to the velocity of order parameter excitations becomes universal ($\sqrt{2}-1$) along the Dirac point splitting direction . For $N_f >1$, we find that fermions are parametrically faster than order parameter excitations in all directions. Our RG analysis is fully controlled by the fact that order parameter and fermion fluctuations are at the upper critical dimension, and thus our stable fixed points demonstrate the presence of weakly coupled quantum criticalities with infinite anisotropy.

Efficient flow monitoring for virtualized applications with eBPF

Subjects: Network flow monitoring, cloud computing, eBPF, cloud-native applications

description: Flow monitoring is widely used to understand the composition of network traffic, which can be used to spot anomalies, attacks, misconfigurations. While dedicated hardware appliances are commonly used in physical infrastructures, efficient software implementations are today required for virtualized and software-defined systems, which are often designed to run in different environments. Traditionally, efficient packet processing in software requires acceleration frameworks kernel-bypass mechanisms, to reduce the overhead. This approach brings large performance gains, but requires additional kernel modules and the re-implementation of common functions of the standard networking stack. In ASTRID, we investigated the usage of the extended Berkeley Packet Filter (eBPF) for effective and efficient packet inspection. Our goal is the implementation of a lightweight flow-monitoring tool that provides similar information as existing appliances but with a reduced execution footprint, in order to be easily integrated in cloud-native applications. The scope is limited to basic flow identification, including most common fields in the IP, ICMP, TCP, end UDP headers, whereas Deep Packet Inspection (DPI) if currently out of the scope.

description: The giant mutually connected component (GMCC) of an interdependent or multiplex network collapses with a discontinuous hybrid transition under random damage to the network. If the nodes to be damaged are selected in a targeted way, the collapse of the GMCC may occur significantly sooner. Finding the minimal damage set which destroys the largest mutually connected component of a given interdependent network is a computationally prohibitive simultaneous optimization problem. We introduce a simple heuristic strategy -- Effective Multiplex Degree -- for targeted attack on interdependent networks that leverages the indirect damage inherent in multiplex networks to achieve a damage set smaller than that found by any other non computationally intensive algorithm. We show that the intuition from single layer networks that decycling (damage of the $2$-core) is the most effective way to destroy the giant component, does not carry over to interdependent networks, and in fact such approaches are worse than simply removing the highest degree nodes.

Critical line in undirected Kauffman boolean networks - the role of percolation

description: We show that to correctly describe the position of the critical line in the Kauffman random boolean networks one must take into account percolation phenomena underlying the process of damage spreading. For this reason, since the issue of percolation transition is much simpler in random undirected networks, than in the directed ones, we study the Kauffman model in undirected networks. We derive the mean field formula for the critical line in the giant component of these networks, and show that the critical line characterizing the whole network results from the fact that the ordered behavior of small clusters shields the chaotic behavior of the giant component. We also show a possible attitude towards the analytical description of the shielding effect. The theoretical derivations given in this paper quite tally with numerical simulations done for classical random graphs.

description: Specifications of the Federal Reserve target rate that have more realistic features mitigate in-sample over-fitting and are favored in the data. Imposing a positivity constraint and discrete increments significantly increases the accuracy of model out-of-sample forecasts for the level and volatility of the Federal Reserve target rates. In addition, imposing the constraints produces different estimates of the response coefficients. In particular, a new and simple specification, where the target rate is the maximum between zero and the prediction of an ordered-choice Probit model, is more accurate and has higher response coefficients to information about inflation and unemployment.
description: Les spécifications relatives au taux cible de la Réserve fédérale comportant des caractéristiques plus réalistes atténuent le risque de surajustement à l’intérieur de l’échantillon et sont privilégiées dans les données. L’imposition d’une contrainte de positivité et de changements discrets augmente considérablement l’exactitude des prévisions hors échantillon issues des modèles pour ce qui est du niveau et de la volatilité du taux cible de la Réserve fédérale. De plus, l’imposition de contraintes donne lieu à des estimations différentes des coefficients de réaction. En particulier, une nouvelle spécification simple où le taux cible correspond à la valeur la plus élevée entre zéro et la prévision d’un modèle probit ordonné présente une plus grande exactitude ainsi que des coefficients de réaction plus élevés à l’égard de l’information sur l’inflation et le chômage.
