Implementing Few-Body Algorithmic Regularization with Post-Newtonian Terms

Year: 2007

description: We discuss the implementation of a new regular algorithm for simulation of the gravitational few-body problem. The algorithm uses components from earlier methods, including the chain structure, the logarithmic Hamiltonian, and the time-transformed leapfrog. This algorithmic regularization code, AR-CHAIN, can be used for the normal N-body problem, as well as for problems with softened potentials and/or with velocity-dependent external perturbations, including post-Newtonian terms, which we include up to order PN2.5. Arbitrarily extreme mass ratios are allowed. Only linear coordinate transformations are used and thus the algorithm is somewhat simpler than many earlier regularized schemes. We present the results of performance tests which suggest that the new code is either comparable in performance or superior to the existing regularization schemes based on the Kustaanheimo-Stiefel (KS) transformation. This is true even for the two-body problem, independent of eccentricity. An important advantage of the new method is that, contrary to the older KS-CHAIN code, zero masses are allowed. We use our algorithm to integrate the orbits of the S stars around the Milky Way supermassive black hole for one million years, including PN2.5 terms and an intermediate-mass black hole. The three S stars with shortest periods are observed to escape from the system after a few hundred thousand years.

description: We extend the analysis of arXiv:0801.4457 [hep-th] to charged black hole solutions of four-dimensional $U(1)^4$ gauged supergravity which carry three charges. There are two decoupling near-horizon limits, one over the near-BPS black hole solution and the other over the near-extremal, but non-BPS geometry. Taking the limit over the eleven dimensional uplift of these black hole solutions, for both of these cases we obtain a geometry which has a piece (conformal) to rotating BTZ $\times S^2$. We study the 4d, $11d$ and $5d, 3d$ black hole properties. Moreover, we show that the BTZ$\times S^2$ geometry obtained after the near-BPS (near-extremal) limit is also a solution to five-dimensional $U(1)^3$ un-gauged (gauged) STU supergravity. Based on these decoupling limits we argue that there should be sectors of 3d CFT resulting from low energy limit of theory on $N$ M2-branes ($N\to \infty)$, which are decoupled from the rest of the theory and are effectively described by a 2d CFT. The central charge of the 2d CFT in both near-BPS and near-extremal case scales as $N$. The engineering dimension of the operators in these decoupled sectors scales as $N^{4/3}$ (for near-BPS case) while as $N^{3/2}$ (for the near-extremal case). Moreover, we discuss the description of the decoupled sectors as certain deformations of $6d$ CFT residing on the intersecting M5-brane giants.

description: The spectra of the planetary nebula M1-42 is reanalysed using spectral measurements made in the mid-infrared with the Spitzer Space Telescope. The aim is to determine the chemical composition of this object. We also make use of ISO, IUE and ground based spectra. Abundances determined from the mid- and far-infrared lines, which are insensitive to electron temperature, are used as the basis for the determination of the composition, which are found to substantially differ from earlier results. High values of neon, argon and sulfur are found. They are higher than in other PN, with the exception of NGC6153, a nebula of very similar abundances. The high values of helium and nitrogen found indicate that the second dredge-up and hot bottom burning has occurred in the course of evolution and that the central star was originally more massive than 4Msun. The present temperature and luminosity of the central star is determined and at first sight may be inconsistent with such a high mass.

description: ANTARES is the largest undersea neutrino telescope and it has been taking data in its final configuration for more than ten years. On their journey to the Earth, cosmic rays can be absorbed by celestial objects, like the Sun, leading to a deficit in the atmospheric muon flux measured by the ANTARES detector, the so-called Sun "shadow" effect. This phenomenon can be used to evaluate fundamental telescope characteristics: the detector angular resolution and pointing accuracy. This work describes the study of the Sun "shadow" effect using the ANTARES data collected between 2008 and 2017. The statistical significance of the Sun shadow observation is $3.7σ$ and the estimated angular resolution value of the ANTARES telescope for downward-going muons is $0.59^{\circ} \pm 0.10^{\circ}$, which is consistent with the expectations obtained from the Monte Carlo simulations and also with the estimation from the Moon "shadow" analysis of 2007-2016 years. No evidence of systematic pointing shift is found and the resulting pointing accuracy is consistent with the expectations.

description: Arp220 is a nearby system in final stages of galaxy merger with powerful ongoing star-formation at and surrounding the two nuclei. Arp 220 was detected in HI absorption and OH Megamaser emission and later recognized as the nearest ultra-luminous infrared galaxy also showing powerful molecular and X-ray emissions. In this paper we review the available radio and mm-wave observational data of Arp 220 in order to obtain an integrated picture of the dense interstellar medium that forms the location of the powerful star-formation at the two nuclei.

Lectotype:— INDIA, Tamil Nadu State, Tinnevelly (Tirunelveli district), without precise locality, April, 1911, Hole s.n., with flowers and fruits (K000800917, digital image!, lectotype designated here; Fig.1); Isolectotype: Tinnevelly (Tirunelveli district), without precise locality, April, 1911, Hole 2946, with flowers and fruits, (CAL000012962, digital image!).
Distribution:—Endemic to Peninsular India (Tamil Nadu; Karnataka, Kerala, and Chhattisgarh).
Notes:— Albizia lathamii was collected by Latham from dry deciduous forests of Tirunelveli and Ramnad (Ramanathapuram) districts at low elevations (300–1,200 ft.), reported to prefer hard red soil rich in disintegrating quartzite (vide Hole, 1912: 156). The endemic legume inhabiting the lower elevations and plains of the Western Ghats extends its distribution to the neighbouring districts in Tamil Nadu [MH: Sirumalai hills, Dindigul district (earlier Madurai dt.), 266 m, K Subramanyam 5352, 13.02.1958; Bodi range, Theni distirct (earlier Madurai dt.), 500 m, K M Sebastine 12904, 15.9.1961]; the recent collection in Tamil Nadu was made by E Vajravelu (MH: 33971, 23.3.1970) from the Western Ghats at Puliyankudi, near Courtallum, Tenkasi district (earlier Tirunelveli dt.) at 250 m altitude and reported it as common. The endemic legume which is considered Critically Endangered. (Sajeev & Sasidharan 1998, Sasidharan 2006, Rivers et al. 2015) was recently found distributed in the Chinnar Wildlife Sanctuary, Kerala (Sajeev & Sasidharan 1998), and from the southern Western Ghats of Karnataka (Singh 1988), and also from Chhattisgarh (earlier part of Madhya Pradesh; Tiwari 1979, cited in Kumar & Sane 2003). The current status of the endemic species needs to be determined through intensive field surveys in the southern Western and Eastern Ghats and the extant populations must be regularly monitored besides initiating ex situ conservation measures to protect this Critically Endangered endemic legume species.

description: Using the GALEX ultraviolet imagers we have observed a region of nebulosity first identified as starlight scattered by interstellar dust by Sandage (1976). Apart from airglow and zodiacal emission, we have found a diffuse UV background of between 500 and 800 \phunit in both the \galex FUV (1350 -- 1750 Å) and NUV (1750 -- 2850 Å). Of this emission, up to 250 \phunit is due to \htwo fluorescent emission in the FUV band; the remainder is consistent with scattering from interstellar dust. We have estimated the optical constants to be $a = 0.3; g = 0.7$ in the FUV and $a = 0.5; g = 0.7$ in the NUV, implying highly forward scattering grains, plus an extragalactic contribution of as much as 150 \phunit. These are the highest spatial resolution observations of the diffuse UV background to date and show an intrinsic scatter beyond that expected from instrumental noise alone. Further modeling is required to understand the nature of this scatter and its implications for the ISM.

The fishermen as predator : numerical responses of British Columbia gillnet fishermen to salmon abundance
Creators: name: Millington, Peter
Publisher: name: University of British Columbia
Year: 2010

description: Fishermen are predators whose functional and numerical responses to prey can be studied. I review the fishery literature and discuss how much of it can be viewed in the context of a predator-prey system. I examined the numerical response, aggregation and movement of boats in response to fish abundance, in the British Columbia salmon gillnet fleet using catch data by area for the period 1979 to 1981. In any one year, for the whole coast, there was a strong relationship between the return (catch value per week per boat) and the number of gillnet boats fishing in the following week. I investigated three hypotheses to explain the within season movement of the gillnet fleet between areas (or sites) along the coast: fixed or traditional movement, which can be equated to an innate pattern of behaviour not substantially modified by learning; movement by fishermen to maximize individual return, which tends to equalize the return per unit time in all sites; and movement in which the drive to maximize individual return is modified by differential foraging costs and benefits between sites. At the individual area level, none of the hypotheses was sufficient to consistently explain the variation in boat numbers within a season. Fixed movement patterns do not adequately explain movement although they may be useful in the short term. Movement by fishermen to maximize individual returns did not consistently explain movement into and out of particular areas, and resultant area returns did not approach the provincial average return. Special features of each area appear to modify fishermen's attempts to maximize their indidividual returns such that each area tends to a characteristic return with respect to adjacent areas in any one year. However there is much variability in these returns between years. I compared the ability of the latter two hypotheses (equalization of return between sites and differential foraging costs) to predict boat numbers in particular areas in the following weeks. In some areas with identifiable features of location or boat type this approach worked well, but in most cases it was confounded by traditional and economic factors. Application of these hypotheses to components of the fleet, such as combination gillnetters and trollers, and pure gillnetters, may provide more insight into the mechanisms driving the numerical response.

description: Wind farm needs prediction models for predictive maintenance. There is a need to predict values of non-observable parameters beyond ranges reflected in available data. A prediction model developed for one machine many not perform well in another similar machine. This is usually due to lack of generalizability of data-driven models. To increase generalizability of predictive models, this research integrates the data mining with first-principle knowledge. Physics-based principles are combined with machine learning algorithms through feature engineering, strong rules and divide-and-conquer. The proposed synergy concept is illustrated with the wind turbine blade icing prediction and achieves significant prediction accuracy across different turbines. The proposed process is widely accepted by wind energy predictive maintenance practitioners because of its simplicity and efficiency. Furthermore, this paper demonstrates the importance of embedding physical principles within the machine learning process, and also highlight an important point that the need for more complex machine learning algorithms in industrial big data mining is often much less than it is in other applications, making it essential to incorporate physics and follow Less is More philosophy.

description: For finite volume field theories with discrete translational invariance, conserved currents can be additively renormalized by infrared effects. We demonstrate this for pions using chiral perturbation theory coupled to electromagnetism in a periodic box. Gauge invariant single particle effective theories are constructed to explain these results. In such theories, current renormalization arises from operators involving the zero mode of the gauge field. No contradictions with Ward identities, or low-energy theorems are encountered.

description: We study the implications and limitations of galaxy cluster surveys for constraining models of particle physics and gravity beyond the Standard Model. Flux limited cluster counts probe the history of large scale structure formation in the universe, and as such provide useful constraints on cosmological parameters. As a result of uncertainties in some aspects of cluster dynamics, cluster surveys are currently more useful for analyzing physics that would affect the formation of structure than physics that would modify the appearance of clusters. As an example we consider the Lambda-CDM cosmology and dimming mechanisms, such as photon-axion mixing.

description: We study how two moduli can be stabilized in a Minkowski/de Sitter vacuum for a wide class of string-inspired Supergravity models with an effective Fayet-like Supersymmetry breaking. It is shown under which conditions this mechanism can be made natural and how it can give rise to an interesting spectrum of soft masses, with a relatively small mass difference between scalar and gaugino masses. In absence of a constant superpotential term, the above mechanism becomes completely natural and gives rise to a dynamical supersymmetry breaking mechanism. Some specific type IIB and heterotic string inspired models are considered in detail.

description: Mixtures are convex combinations of laws. Despite this simple definition, a mixture can be far more subtle than its mixed components. For instance, mixing Gaussian laws may produce a potential with multiple deep wells. We study in the present work fine properties of mixtures with respect to concentration of measure and Sobolev type functional inequalities. We provide sharp Laplace bounds for Lipschitz functions in the case of generic mixtures, involving a transportation cost diameter of the mixed family. Additionally, our analysis of Sobolev type inequalities for two-component mixtures reveals natural relations with some kind of band isoperimetry and support constrained interpolation via mass transportation. We show that the Poincaré constant of a two-component mixture may remain bounded as the mixture proportion goes to 0 or 1 while the logarithmic Sobolev constant may surprisingly blow up. This counter-intuitive result is not reducible to support disconnections, and appears as a reminiscence of the variance-entropy comparison on the two-point space. As far as mixtures are concerned, the logarithmic Sobolev inequality is less stable than the Poincaré inequality and the sub-Gaussian concentration for Lipschitz functions. We illustrate our results on a gallery of concrete two-component mixtures. This work leads to many open questions.

description: We consider a cosmological scenario in which the very early Universe experienced a transient epoch of matter domination due to the formation of a large population of primordial black holes (PBHs) with masses $M \lesssim 10^{9}\,\textrm{g}$, that evaporate before Big Bang nucleosynthesis. In this context, Hawking radiation would be a non-thermal mechanism to produce a cosmic background of axion-like particles (ALPs). We assume the minimal scenario in which these ALPs couple only with photons. In the case of ultralight ALPs ($m_a \lesssim 10^{-9}\,\textrm{eV}$) the cosmic magnetic fields might trigger ALP-photon conversions, while for masses $m_a \gtrsim 10\,\textrm{eV}$ spontaneous ALP decay in photon pairs would be effective. We investigate the impact of these mechanisms on the cosmic X-ray background, on the excess in X-ray luminosity in Galaxy Clusters, and on the process of cosmic reionization.

description: We explore the properties of dark matter in theories with two universal extra dimensions, where the lightest Kaluza-Klein state is a spin-0 neutral particle, representing a six-dimensional photon polarized along the extra dimensions. Annihilation of this 'spinless photon' proceeds predominantly through Higgs boson exchange, and is largely independent of other Kaluza-Klein particles. The measured relic abundance sets an upper limit on the spinless photon mass of 500 GeV, which decreases to almost 200 GeV if the Higgs boson is light. The phenomenology of this dark matter candidate is strikingly different from Kaluza-Klein dark matter in theories with one universal extra dimension. Elastic scattering of the spinless photon with quarks is helicity suppressed, making its direct detection challenging, although possible at upcoming experiments. The prospects for indirect detection with gamma rays and antimatter are similar to those of neutralinos. The rates predicted at neutrino telescopes are below the sensitivity of next-generation experiments.

Productivity and diversity of rocky intertidal macroalgae in relation to a seasonally fluctuating environment
Creators: name: Pecchioli, Joel Albert
Publisher: name: University of British Columbia
Year: 2010

description: The productivity, diversity and community structure of the intertidal macroalgal community in the vicinity of Bamfield, B.C. Canada were studied over a fifteen month period (June 1982 to August 1983). Four study sites were examined as representative along a gradient of wave exposure. Algal standing crops were estimated at semi-weekly intervals; these data were used to calculate algal diversity and, in conjunction with concurrent measurements of photosynthesis, algal productivity. Fucus distichus was most abundant at the upper levels of the three more sheltered sites where it formed an extensive canopy. The lower shore at the sheltered sites was characterized by a series of spring/summer annual and ephemeral species (Leathesia difformis, Cryptosiphonia wood, Ulva fenestrata , etc.). As wave exposure increased, F. distichus abundance decreased. Mid-shore levels at the exposed site were characterized by an "algal turf" while lower levels were dominated by Hedophyllum sessile Standing crop of all species was greatest in spring/summer and least in winter. At the sheltered sites, diversity was very low in those areas dominated by F. distichus and greater on lower levels of the shore. Diversity was greatest in the mid-shore "algal turf" assemblage at the exposed site and lower in the distichus (upper) and H. sessile (lower) dominated zones. It was proposed that the observed vertical (tidal height), horizontal (wave exposure) and seasonal patterns of algal diversity were the result of the interactive effects of wave action and desiccation stress. Herbivory (by Littorina scutulata and L. sitkana ) and the presence of a F. distichus canopy were secondary influences. Net daily photosynthesis in F. distichus was greatest during the spring and early summer and was positively correlated with water temperature. Photosynthetic rates varied little throughout the year, indicating that daylength, and not photon flux density per se, was more responsible for the observed seasonal differences in net daily photosynthesis. Positive net daily productivity was observed all year, but increased wave action during the fall/winter limited algal standing crops. It was proposed that F. distichus productivity is limited by wave action in the fall and winter and nutrient/desiccation stress during the summer.

Di chi sono questi buoi? Problemi di attribuzione della proprietà dell' Inno a Ermes

Year: 2012

description: Many scholars assumed that the Hymn to Hermes is constitued by  building blocks, so to speak (a kind of erratic narrative!), and that  the famous cattle-raiding must be considered one of them. Within the  context of the Hymn, Hermes is described as the "last born", the last  son in a cosmos where everything (timai in particular) has been  divided and already distribued; the new-born god has almost nothing left  for him and can only obtain his place in the Olympian universe by theft  or exchange. As a general statement, the cows stolen under Olympus are  Apollo's ones. This evidence is confirmed by intertextual and (some)  extratextual allusions, but we can by no means take it for granted; what  I am suggesting is that the property of these cows are not so certain  and that, by a deeper insight into the text, we could even find it  doubtful; I shall argue that the very property of the cattle is one of  the weapons used by Hermes to gain his prerogatives and, ultimately, his  place within the divine order.

description: Numerous theoretical and experimental arguments are presented in favor of the generation of intermediate $σ$-dressed dibaryon in $NN$ interaction at intermediate and short distances. We argue that this intermediate dibaryon can be responsible for the strong intermediate-range attraction and the short-range repulsion in the $NN$ interaction, and also for the short-range correlations in nuclei. The suggested mechanism for the $σ$-dressing of the dibaryon is identical to that which explains the Roper resonance structure, its dominant decay modes and its extraordinary low mass. A similar transformation mechanism from the glue to the scalar field was discovered in $J/Ψ$ decays. The new experimental data on 2$π$-production in the scalar-isoscalar channel produced in $pn$- and $pd$-collisions and in particular the very recent data on $γγ$ correlations in $p$C and $d$C scattering in the GeV region seems to corroborate the existence of the $σ$-dressed dibaryon in two- and three nucleon interactions.

An Almost-Optimally Fair Three-Party Coin-Flipping Protocol

Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: In a multiparty fair coin-flipping protocol, the parties output a common (close to) unbiased bit, even when some corrupted parties try to bias the output. Cleve [STOC 1986] has shown that in the case of dishonest majority (i.e., at least half of the parties can be corrupted), in any $m$-round coin-flipping protocol the corrupted parties can bias the honest parties' common output bit by $Ω(\frac1{m})$. For more than two decades the best known coin-flipping protocols against dishonest majority had bias $Θ(\frac{\ell}{\sqrt{m}})$, where $\ell$ is the number of corrupted parties. This was changed by a recent breakthrough result of Moran et al. [TCC 2009], who constructed an $m$-round, two-party coin-flipping protocol with optimal bias $Θ(\frac1{m})$. In a subsequent work, Beimel et al. [Crypto 2010] extended this result to the multiparty case in which less than $\frac23$ of the parties can be corrupted. Still for the case of $\frac23$ (or more) corrupted parties, the best known protocol had bias $Θ(\frac{\ell}{\sqrt{m}})$. In particular, this was the state of affairs for the natural three-party case. We make a step towards eliminating the above gap, presenting an $m$-round, three-party coin-flipping protocol, with bias $\frac{O(\log^3 m)}m$. Our approach (which we also apply for the two-party case) does not follow the "threshold round" paradigm used in the work of Moran et al. and Beimel et al., but rather is a variation of the majority protocol of Cleve, used to obtain the aforementioned $Θ(\frac{\ell}{\sqrt{m}})$-bias protocol.

Lower Bounds for the Size of Random Maximal H-Free Graphs

description: We consider the next greedy randomized process for generating maximal H-free graphs: Given a fixed graph H and an integer n, start by taking a uniformly random permutation of the edges of the complete n-vertex graph. Then, construct an n-vertex graph, M_n(H), iteratively as follows. Traverse the permuted edges of the complete n-vertex graph and add each one to the (initially empty) evolving graph M_n(H) - unless its addition creates a copy of H. The result of this process is a maximal H-free graph M_n(H). The basic question we are concerned with in here is: What is the expected number of edges in M_n(H)? We give new lower bounds on the expected number of edges in M_n(H) for the case where H is a regular, strictly 2-balanced graph. In particular, we obtain new lower bounds for Turan numbers of complete balanced bipartite graphs K_{r,r}, for every fixed r > 4. This improves an old lower bound of Erdos and Spencer.

Localization for ensemble DA: objective diagnostic and effcient application

Publisher: name: Zenodo
Year: 2019
Subjects: data assimilation, ensemble, localization

description: Presentation given at the Workshop on Climate Prediction in the Atlantic-Arctic sector, 7th June 2019.

Abstract: Localization is a key aspect of ensemble data assimilation. Its purpose is to reduce the sampling noise affecting covariances estimated with ensembles of limited size. It is necessary for both variational methods (EnVar) and Ensemble Kalman Filter-related methods, but applied in different spaces for this two kinds of methods. The localization function can be diagnosed objectively by combining elements of the sample covariance estimation theory and the linear filtering theory, as shown in Menetrier et al. (2015 a,b). Recent developments of explicit convolution methods to apply localization functions have shown a promising potential for coupled DA systems.

description: Cavity quantum electrodynamics (cavity QED) describes the coherent interaction between matter and an electromagnetic field confined within a resonator structure, and is providing a useful platform for developing concepts in quantum information processing. By using high-quality resonators, a strong coupling regime can be reached experimentally in which atoms coherently exchange a photon with a single light-field mode many times before dissipation sets in. This has led to fundamental studies with both microwave and optical resonators. To meet the challenges posed by quantum state engineering and quantum information processing, recent experiments have focused on laser cooling and trapping of atoms inside an optical cavity. However, the tremendous degree of control over atomic gases achieved with Bose-Einstein condensation has so far not been used for cavity QED. Here we achieve the strong coupling of a Bose-Einstein condensate to the quantized field of an ultrahigh-finesse optical cavity and present a measurement of its eigenenergy spectrum. This is a conceptually new regime of cavity QED, in which all atoms occupy a single mode of a matter-wave field and couple identically to the light field, sharing a single excitation. This opens possibilities ranging from quantum communication to a wealth of new phenomena that can be expected in the many-body physics of quantum gases with cavity-mediated interactions.

description: In their book Rapoport and Zink constructed rigid analytic period spaces for Fontaine's filtered isocrystals, and period morphisms from moduli spaces of p-divisible groups to some of these period spaces. We determine the image of these period morphisms, thereby contributing to a question of Grothendieck. We give examples showing that only in rare cases the image is all of the Rapoport-Zink period space.

Dimension minimization of a quantum automaton

description: A new model of a Quantum Automaton (QA), working with qubits is proposed. The quantum states of the automaton can be pure or mixed and are represented by density operators. This is the appropriated approach to deal with measurements and dechorence. The linearity of a QA and of the partial trace super-operator, combined with the properties of invariant subspaces under unitary transformations, are used to minimize the dimension of the automaton and, consequently, the number of its working qubits. The results here developed are valid wether the state set of the QA is finite or not. There are two main results in this paper: 1) We show that the dimension reduction is possible whenever the unitary transformations, associated to each letter of the input alphabet, obey a set of conditions. 2) We develop an algorithm to find out the equivalent minimal QA and prove that its complexity is polynomial in its dimension and in the size of the input alphabet.

The role of catecholamines in erythrocyte pH regulation and oxygen transport in rainbow trout (Salmo gairdneri) during and following exhaustive activity
Creators: name: Primmett, Dennis R. N.

description: The role of endogenous plasma catecholamines in erythrocyte pH regulation and blood oxygen transport in freshwater rainbow trout (Salmo gairdneri) was examined. The fish were subjected to anaerobic exercise followed by aerobic exercise at 80% of their critical swimming velocity. The anaerobic exercise was found to result in a substantial extracellular acidosis, increased plasma catecholamine concentrations, increased blood oxygen levels, and increased erythrocytic pH. The transition from anaerobic to near-maximal aerobic exercise seemed to produce a temporary unsteady 6tate in the ventilation/perfusion properties of the oxygen uptake system; however, a new steady state was achieved within one hour of aerobic recovery. Anaerobic exercise followed by propranolol treatment resulted in a significant decrease in erythrocytic pH concurrent to the extracellular acidosis but blood oxygen levels were unchanged; it was assumed that the lack of a Root effect during red cell acidosis was due to secondary effects of propranolol on erythrocytes. It was concluded that adrenergic regulation of red cell pH in freshwater rainbow trout allowed normal haemoglobin-oxygen carriage during plasma acid-base disturbances resulting from strenuous exercise.

description: We argue that the phenomena of distributed responsibility, induced acceptance, and acceptance through ignorance constitute instances of imperfect delegation when tasks are delegated to computationally-driven systems. Imperfect delegation challenges human accountability. We hold that both direct public accountability via public transparency and indirect public accountability via transparency to auditors in public organizations can be both instrumentally ethically valuable and required as a matter of deontology from the principle of democratic self-government. We analyze the regulatory content of 16 guideline documents about the use of AI in the public sector, by mapping their requirements to those of our philosophical account of accountability, and conclude that while some guidelines refer to processes that amount to auditing, it seems that the debate would benefit from more clarity about the nature of the entitlement of auditors and the goals of auditing, also in order to develop ethically meaningful standards with respect to which different forms of auditing can be evaluated and compared.
