description: With the emergence of very high energy astronomy (VHE; E>100 GeV), new open questions were presented to astronomers studying the multi-wavelength emission from blazars. Answers to these open questions, such as the Doppler crisis, and finding the location of the high-energy activity have eluded us thus far. Recently, quasi-simultaneous multi-wavelength monitoring programs have shown considerable success in investigating blazar activity. After the launch of the Fermi Gamma-ray Space Telescope in 2008, such quasi-simultaneous observations across the electromagnetic spectrum became possible. In addition, with very long baseline interferometry (VLBI) observations we can resolve the central parsec region of active galactic nuclei (AGN) and compare morphological changes to the gamma-ray activity to study high-energy emitting blazars. To achieve our goals, we need sensitive, long-term VLBI monitoring of a complete sample of VHE detected AGN. We performed VLBI observations of TeV-detected AGN and high likelihood neutrino associations as of December of 2021 with the Long Baseline Array (LBA) and other southern hemisphere radio telescopes at 2.3 GHz. In this paper we present first light TANAMI S-band images, focusing on the TeV-detected sub-sample of the full TANAMI sample. Apart from these very high energy-detected sources, we also show images of the two flux density calibrators and two additional sources included in the observations. We study the redshift, 0.1-100 GeV photon flux and S-band core brightness temperature distributions of the TeV-detected objects, and find that flat spectrum radio quasars and low synchrotron peaked sources on average show higher brightness temperatures than high-synchrotron-peaked BL Lacs. Sources with bright GeV gamma-ray emission also show higher brightness temperature values than gamma-low sources.

Central bank independence and inflation performance: panacea or placebo?
Creators: name: JENKINS, M.A.
Publisher: name: PSL Quarterly Review
Year: 2013
Subjects: subject: Inflation, Central banks
subject: E58

description: A great deal of recent attention has been devoted towards the relationship between central bank independence and economic performance. The degree of central bank independence is said to determine cross-country inflation differences. However, several factors have been raised that cast doubts on such a relationship. First, the link between independence and inflation may not be as tight as previously declared. Also, predictive validity tests show that the link does not score favourably. Relevant variables also appear to have been omitted in using central bank independence as the determinant of cross-country inflation differences. This paper investigates the stylised facts regarding central bank independence and inflation performance. The structure of the labor market, the regulatory burden of the central bank and the exchange rate regime are found to be significant determinants as well. JEL Codes: E58

Quantum Financial Modeling on Noisy Intermediate-Scale Quantum Hardware: Random Walks using Approximate Quantum Counting

description: Quantum computers are expected to contribute more efficient and accurate ways of modeling economic processes. Quantum hardware is currently available at a relatively small scale, but effective algorithms are limited by the number of logic gates that can be used, before noise from gate inaccuracies tends to dominate results. Some theoretical algorithms that have been proposed and studied for years do not perform well yet on quantum hardware in practice. This encourages the development of suitable alternative algorithms that play similar roles in limited contexts.
 This paper implements this strategy in the case of quantum counting, which is used as a component for keeping track of position in a quantum walk, which is used as a model for simulating asset prices over time. We introduce quantum approximate counting circuits that use far fewer 2-qubit entangling gates than traditional quantum counting that relies on binary positional encoding. The robustness of these circuits to noise is demonstrated.
 We compare the results to price change distributions from stock indices, and compare the behavior of quantum circuits with and without mid-measurement to trends in the housing market. The housing data shows that low liquidity brings price volatility, as expected with the quantum models.
An Allgravity as a Grand Unification of Forces

Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: To each type of Coulomb (Newton) charge corresponds a kind of Coulomb (Newton) mass. Such a mass-charge duality explains the availability in a neutrino of the united rest mass and charge equal to all its mass and charge consisting of the electric, weak, strong and the range of other the innate components. A neutrino itself, similarly to all other the quantum matter with Coulomb (Newton) mass and charge, says herewith in favor of a kind of mononeutrino with magnetocoulomb (magnetonewton) rest mass and charge equal to all its mass and charge including the magnetoelectric, magnetoweak, magnetostrong and the range of other the innate parts. We discuss a theory in which symmetry between electricity and magnetism comes forward at the level of a grand unification mathematical logic as the defined symmetry between gravity and magnetogravity within the same allgravity responsible for all that in a curved space-time. This allgravity relates graviton and monograviton as a consequence of force unification forming one single allgraviton. Thereby, it establishes a set of forces and a role in their formation of mass, charge and thus directly reveals so far unknown most diverse properties of a curved space.

description: Achiral molecules can be made temporarily chiral by excitation with electric fields, in the sense that an average over molecular orientations displays a net chiral signal [Tikhonov et al., Sci. Adv. 8, eade0311 (2022)]. Here, we go beyond the assumption of molecular orientations to remain fixed during the excitation process. Treating both rotations and vibrations quantum mechanically, we identify conditions for the creation of chiral vibrational wavepackets -- with net chiral signals -- in ensembles of achiral molecules which are initially randomly oriented. Based on the analysis of symmetry and controllability, we derive excitation schemes for the creation of chiral wavepackets using a combination of (a) microwave and IR pulses and (b) a static field and a sequence of IR pulses. These protocols leverage quantum rotational dynamics for pump-probe spectroscopy of chiral vibrational dynamics, extending the latter to regions of the electromagnetic spectrum other than the UV.

description: It has been observed that several Milky Way (MW) satellite dwarf galaxies are distributed along a coherent planar distribution known as the Vast Polar Structure (VPOS). Here we investigate whether MW satellites located on the VPOS have different physical and orbital properties from those not associated with it. Using the proper motion measurements of the MW satellites from the \textit{Gaia} mission and literature values for their observational parameters, we first discriminate between systems that may or may not be associated with the VPOS, and then compare their chemical and dynamical properties. Comparing the luminosity distributions of the on-plane and off-plane samples, we find an excess of bright satellites observed on the VPOS. Despite this luminosity gap, we do not observe a significant preference for on-plane and off-plane systems to follow different scaling relations. The on-plane systems also show a striking pattern in their radial velocities and orbital phases: co-orbiting satellites are almost all approaching their pericenters, while both counter-orbiting satellites are leaving their last pericenters. This contrasts with the more random distribution of the off-plane sample. The on-plane systems also tend to have the lowest orbital energies for a given value of angular momentum. These results are robust to the assumed MW potential, even in the case of a potential perturbed by the arrival of a massive LMC. Considering them a significant property of the VPOS, we explore several scenarios, all related to the late accretion of satellite systems, which interpret the VPOS as a young structure. We hypothesise that the VPOS formed as a result of the accretion of a group of dwarf galaxies. More accurate proper motions and dedicated studies in the context of cosmological simulations are needed to confirm this scenario.

Infinite-dimensional gradient-based descent for alpha-divergence minimisation

Publisher: name: arXiv

description: This paper introduces the $(α, Γ)$-descent, an iterative algorithm which operates on measures and performs $α$-divergence minimisation in a Bayesian framework. This gradient-based procedure extends the commonly-used variational approximation by adding a prior on the variational parameters in the form of a measure. We prove that for a rich family of functions $Γ$, this algorithm leads at each step to a systematic decrease in the $α$-divergence and derive convergence results. Our framework recovers the Entropic Mirror Descent algorithm and provides an alternative algorithm that we call the Power Descent. Moreover, in its stochastic formulation, the $(α, Γ)$-descent allows to optimise the mixture weights of any given mixture model without any information on the underlying distribution of the variational parameters. This renders our method compatible with many choices of parameters updates and applicable to a wide range of Machine Learning tasks. We demonstrate empirically on both toy and real-world examples the benefit of using the Power descent and going beyond the Entropic Mirror Descent framework, which fails as the dimension grows.

description: The free-trade argument as situated in the normative dimension of orthodox theory had an explicit prescriptive role of expressing that free trade is efficient. Moreover, the factor-price equalisation theorem as framed in the positive dimension of orthodox theory served an implicit prescriptive role stating that free trade is also equitable. As evidenced by the influence of political realities the developments in the international trading system, there has been variation in the application of the free trade doctrine across time. The evolution of economic thinking about free trade is examined. Amongst the important issues explored are the reasons for departure from free trade. The reality of the present pattern of free trade is considered in the light of the Uruguay Round agreement. JEL Codes: F13

description: The measurement of risks associated with options is a complex business for a number of reasons. Firstly, option prices tend to be influenced in a non-linear manner by several variables. Unanticipated changes in the price or volatility of the underlying security or changes in interest rates are just some examples of these factors affecting risk measurement. Another reason why option-related risks are difficult to measure is that such risks should be examined in relation to other positions. The nature of the risks involved in options are clarified in order to help assess whether the various capital adequacy requirements proposed are reasonable. Four different bank capital adequacy schemes are examined. JEL Codes: G10

description: The Exchange Rate Mechanism 2 (ERM2) framework promises a stronger and closer relationship between the euro and potential non-euro members of the EU. The central factor of the relationship will depend on the progress of the economic convergence of participating countries. ERM2 provides for a suspension of intervention and financing by the European Central Bank (ECB) and non-euro banks during price stabilisation. It clearly indicates an exchange rate objective that is geared towards non-inflationary economic and monetary policies. An examination is undertaken of how best to organise monetary and exchange rate policy cooperation between the euro area and these other EU countries. JEL Codes: F15, E52

description: This work focuses on the numerical modelling of confined concretes when subjected to multiaxial loading accounting for a nonlinear material response. Particularly, an improved return mapping procedure is here presented to cope with the issue of singularities (corners) in the yield surface, able to catch locally the optimal return point on the active yield surface. The algorithm is applied to the Menetry and Willam's yield surface, with a plastic potential as suggested by Grassl and the softening law proposed by Cervenka suitable for concrete materials. The model capabilities to reproduce the confined behaviour of concrete, as well as its post-peak behaviour, and to predict perfect plasticity or softening are here discussed. The proposed approach can be applied to any elastoplastic material with singular yield surface along the hydrostatic axis.

Inflation, unemployment and the position of the central bank: the opinion of the public

Publisher: name: PSL Quarterly Review
Year: 2013
Subjects: subject: Domestic Monetary Policy, Public opinion
subject: E52, E58

description: Recent theoretical developments in monetary policy are based on the view that the effectiveness of monetary policy is strongly influenced by the interaction between the behaviour of the monetary policy-makers and the private sector. Optimal monetary policy and the possible desirability of central bank independence are directly related to respective assumptions about the information and opinion of the private sector. These assumptions are tested in Italy and the Netherlands. Surveys conducted through telephone and face-to-face interviews show central bank independence and future inflation estimates that are higher among people with higher education and lower for those with lower education. Also revealed is a central bank that is more concerned with unemployment and a government that is concerned with inflation. The glaring result, however, is the public's lack of awareness about a trade-off between inflation and unemployment. JEL Codes: E52, E58

subject: E00, G34

description: From the middle of 1993, the French government has followed an ambitious privatisation programme. Nine major state-owned enterprises have been at least partially sold; other companies some of which are amongst the largest in France, will be sold in the next few years. An analysis is undertaken of how the post-1993 privatisations have related to changes in both the mechanisms of corporate governance and the market for corporate control. Privatisation in France is found to be tactically motivated rather than being spurred by efficiency. Privatisation opened more political than economic opportunities, and corporate governance stayed in stable entities to protect managers from take-over threats. However, a move that will allow organisational competition between Anglo-Saxon and German-Japanese mechanisms may further improve governance of large French corporations. JEL Codes: E00, G34

description: The fluid-gravity correspondence is a duality between anti-de Sitter Einstein gravity and a relativistic fluid living at the conformal boundary. We show that one can accommodate the causal first-order viscous hydrodynamics recently developed by Bemfica, Disconzi, Noronha, and Kovtun in this framework, by requiring a set of natural conditions for the geometric data at the horizon. The latter hosts an induced Carrollian fluid, whose equations of motion are shown to be tightly tied to the ones describing the fluid at the boundary. Functional expressions for the transport coefficients are found --with those associated to viscosity and heat flux uniquely determined--, satisfying a set of known causality requirements for the underlying equations of motion.

description: We study Berry connection polarizability (BCP) induced electric polarization and third-order Hall (TOH) effect in a two-dimensional electron/hole gas (2DEG/2DHG) with Rashba-Dresselhaus (RD) spin-orbit couplings in III-V semiconductor heterostructures. The electric polarization decreases with the increase of the Fermi energy and is responsive to the electric field orientation in the presence of RD spin-orbit couplings for both systems. We determine the BCP-induced TOH conductivity ($χ_{\perp}^{\text{I}}$) along with the TOH conductivity associated with the band velocity ($χ_{\perp}^{\text{II}}$). We find that the presence of an infinitesimal amount of Dresselhaus coupling in addition to the dominant Rashba coupling results in finite TOH responses. These conductivities vanish when the field is aligned with and/or orthogonal to the symmetry lines $k_x\pm k_y=0$ in both systems. For typical system parameters in a 2DEG with $k$-linear RD interactions, the magnitude of $χ_{\perp}^{\text{I}}$ is smaller than that of $χ_{\perp}^{\text{II}}$. On the other hand, when both the SO couplings are comparable, $χ_{\perp}^{\text{I}}$ shows a notable increase in magnitude, owing to the distinctive characteristics of BCP. The TOH conductivity of 2DEG remains unchanged when Rashba and Dresselhaus spin-orbit couplings are exchanged. For 2DHG with $k$-cubic RD interactions, $χ_{\perp}^{\text{I},h}$ exhibits a larger magnitude compared to $χ_{\perp}^{\text{II},h}$. Unlike the electron case, the BCP induced $χ_{\perp}^{\text{I},h}$ alters under the exchange of spin-orbit coupling parameters, whereas $χ_{\perp}^{\text{II},h}$ remains the same.

What really matters: conservativeness or independence?
Creators: name: DE HAAN, J.

Publisher: name: PSL Quarterly Review
Year: 2013
Subjects: subject: Financial Systems and central banks
subject: E58, G20

description: Contemporary views often support the idea that a high level of central bank independence, together with a clear mandate for it to restrain inflation, are important institutional devices for maintaining price stability. The meaning and policy implications of central bank independence are discussed. Two indicators of central bank independence are tested, and it is shown that 'instrument independence' (the freedom of a central bank to choose its policy means) is important for inflation performance, but other aspects of central bank independence and 'conservativeness' have little or no impact on inflation.

description: We provide the first supersymmetric embedding of an integrable $λ$-deformation to type-II supergravity. Specifically, that of the near horizon of the NS1-NS5 brane intersection, geometrically corresponding to $AdS_3 \times S^3 \times T^4$. We show that the deformed background preserves 1/4 of the maximal supersymmetry. In the Penrose limit we show that it preserves no-more than one half of the maximal supersymmetry.

description: We present a detailed study of the local atomic and magnetic structure of the type-I multiferroic perovskite system (Sr,Ba)(Mn,Ti)O$_3$ using x-ray and neutron pair distribution function (PDF) analysis, polarized neutron scattering, and muon spin relaxation ($μ$SR) techniques. The atomic PDF analysis reveals widespread nanoscale tetragonal distortions of the crystal structure even in the paraelectric phase with average cubic symmetry, corresponding to incipient ferroelectricity in the local structure. Magnetic PDF analysis, polarized neutron scattering, and $μ$SR likewise confirm the presence of short-range antiferromagnetic correlations in the paramagnetic state, which grow in magnitude as the temperature approaches the magnetic transition. We show that these short-range magnetic correlations coincide with a reduction of the tetragonal (i.e. ferroelectric) distortion in the average structure, suggesting that short-range magnetism can play an important role in magnetoelectric and/or magnetostructural phenomena even without genuine long-range magnetic order. The reduction of the tetragonal distortion scales linearly with the local magnetic order parameter, pointing to spontaneous linear magnetoelectric coupling in this system. These findings provide greater insight into the multiferroic properties of (Sr,Ba)(Mn,Ti)O$_3$ and demonstrate the importance of investigating the local atomic and magnetic structure to gain a deeper understanding of the intertwined degrees of freedom in multiferroics.

The first-order factorizable contributions to the three-loop massive operator matrix elements $A_{Qg}^{(3)}$ and $ΔA_{Qg}^{(3)}$

description: The unpolarized and polarized massive operator matrix elements $A_{Qg}^{(3)}$ and $ΔA_{Qg}^{(3)}$ contain first-order factorizable and non-first-order factorizable contributions in the determining difference or differential equations of their master integrals. We compute their first-order factorizable contributions in the single heavy mass case for all contributing Feynman diagrams. Moreover, we present the complete color-$ζ$ factors for the cases in which also non-first-order factorizable contributions emerge in the master integrals, but cancel in the final result as found by using the method of arbitrary high Mellin moments. Individual contributions depend also on generalized harmonic sums and on nested finite binomial and inverse binomial sums in Mellin $N$-space, and correspondingly, on Kummer-Poincaré and square-root valued alphabets in Bjorken-$x$ space. We present a complete discussion of the possibilities of solving the present problem in $N$-space analytically and we also discuss the limitations in the present case to analytically continue the given $N$-space expressions to $N \in \mathbb{C}$ by strict methods. The representation through generating functions allows a well synchronized representation of the first-order factorizable results over a 17-letter alphabet. We finally obtain representations in terms of iterated integrals over the corresponding alphabet in $x$-space, also containing up to weight {\sf w = 5} special constants, which can be rationalized to Kummer-Poincaré iterated integrals at special arguments. The analytic $x$-space representation requires separate analyses for the intervals $x \in [0,1/4], [1/4,1/2], [1/2,1]$ and $x > 1$. We also derive the small and large $x$ limits of the first-order factorizable contributions.

Quels sont les ancêtres des bibles portatives? Enquête sur les bibles de petite taille antérieures au XIIIe siècle
Creators: name: Ruzzier, Chiara
Publisher: name: Scrineum Rivista
Year: 2021

description: The article studies the codicological and textual features of seven complete Latin Bibles (pandects) dating to the second half of the 12th century and of different origins (England, France and southern Italy) and places their production within that of complete medieval bibles. During the 12th century the majority of Bibles are large manuscripts, often in two or three volumes, while these specimens are significantly smaller than the average. They represent the first attempts to produce Bibles in a handy format and probably intended for personal reading. The article focuses on the pandects’ layout and compares the different strategies implemented to reduce the size while preserving readability. It attempts to assess whether these manuscripts are a prelude to the production of portable bibles of the 13th century.

Operator dynamics in Lindbladian SYK: a Krylov complexity perspective

description: We use Krylov complexity to study operator growth in the $q$-body dissipative SYK model, where the dissipation is modeled by linear and random $p$-body Lindblad operators. In the large $q$ limit, we analytically establish the linear growth of two sets of coefficients for any generic jump operators. We numerically verify this by implementing the bi-Lanczos algorithm, which transforms the Lindbladian into a pure tridiagonal form. We find that the Krylov complexity saturates inversely with the dissipation strength, while the dissipative timescale grows logarithmically. This is akin to the behavior of other $\mathfrak{q}$-complexity measures, namely out-of-time-order correlator (OTOC) and operator size, which we also demonstrate. We connect these observations to continuous quantum measurement processes. We further investigate the pole structure of a generic auto-correlation and the high-frequency behavior of the spectral function in the presence of dissipation, thereby revealing a general principle for operator growth in dissipative quantum chaotic systems.

Sul S. Pantaleo 8 della Biblioteca Nazionale Centrale di Roma: una miscellanea dantesca di metà Trecento
Creators: name: Signorini, Maddalena
Publisher: name: Scrineum Rivista
Year: 2021

description: The article discusses the MS S. Pantaleo 8, a remarkable collection of Dante’s works now kept at the Biblioteca Nazionale Centrale in Rome. By investigating how the manuscript was prepared, and on the basis of the eight different writings of the scribes who copied the texts, as well as of the work of the three illuminators involved in the decoration of the book, the author suggests that the manuscript might have been copied around the mid-14th century either in eastern Tuscany or in Umbria.

Communes et omnibus notas. Sulla relazione tra litterae communes e rudimenta litterarum fra età tar-doantica e precarolingia
Creators: name: Boccuzzi, Maria
Publisher: name: Scrineum Rivista
Year: 2021

description: This paper focuses on the interrelated meanings of the expression litterae communes as attested in different types of sources. One group of texts includes a law issued by the emperors Valentinian and Valens and one of the Justinian’s novels; here litterae communes is employed to refer to the minuscule writing system of the new Roman cursive, which was widespread in documentary practices outside the imperial chancery and, more generally, in current uses since the 4th century onwards. Another type of sources comprises pedagogical-grammatical texts from Late Antiquity to early Middle Ages, where the expression litterae communes relates to the rudimenta litterarum that could be learnt through primary education. The convergence point between these seemingly different meanings lies in the letterforms used for teaching/learning writing, as revealed by the comparison between the graphic models at the basis of elementary writings and the scripts employed for pragmatic purposes from Late Antiquity to Precarolingian Age.

Currency board or central bank? Lessons from the Irish pound’s link with sterling, 1928-79
Creators: name: HONOHAN, P.
Publisher: name: PSL Quarterly Review
Year: 2013
Subjects: subject: Financial systems and central banks
subject: E58, G20

description: The resurgence of interest in currency boards prompts reconsideration of one of the Irish experience. The authors evaluate the institutional arrangements which underpinned the Irish pound for a half-century. While the regime did have a credibility which led to low interest rates and a degree of price stability, its resilience was partly due to the large additional foreign reserves held by the private banking system and to the fact that the sterling proved not to be a very strong currency. However, an attempt in 1955 to evade the interest rate discipline of the regime was quickly punished, with far-reaching policy consequences. JEL Codes: E58, G20
