Experimental Review of Baryons in the Nuclear Medium

Inclusive studies of nuclear photoabsorption have provided clear evidence of medium modifications but the results have not yet been explained in a model independent way. A deeper understanding of the situation is anticipated from a detailed experimental study of meson photoproduction from nuclei in exclusive reactions. Recent results on meson production in photonuclear experiments indicate a large difference between quasifree meson production from the nuclear surface and non-quasifree components.Comment: Proceedings Baryons200

Lessons from GDPR for AI Policymaking

The ChatGPT chatbot has not just caught the public imagination; it is also amplifying concern across industry, academia, and government policymakers interested in the regulation of Artificial Intelligence (AI) about how to understand the risks and threats associated with AI applications. Following the release of ChatGPT, some EU regulators proposed changes to the EU AI Act to classify AI systems like ChatGPT that generate complex texts without any human oversight as “high-risk” AI systems that would fall under the law’s requirements. That classification was a controversial one, with other regulators arguing that technologies like ChatGPT, which merely generate text, are “not risky at all.” This controversy risks disrupting coherent discussion and progress toward formulating sound AI regulations for Large Language Models (LLMs), AI, or ICTs more generally. It remains unclear where ChatGPT fits within AI and where AI fits within the larger context of digital policy and the regulation of ICTs in spite of nascent efforts by OECD.AI and the EU. This paper aims to address two research questions around AI policy: (1) How are LLMs like ChatGPT shifting the policy discussions around AI regulations? (2) What lessons can regulators learn from the EU’s General Data Protection Regulation (GDPR) and other data protection policymaking efforts that can be applied to AI policymaking? The first part of the paper addresses the question of how ChatGPT and other LLMs have changed the policy discourse in the EU and other regions around regulating AI and what the broader implications for these shifts may be for AI regulation more widely. This section reviews the existing proposal for an EU AI Act and its accompanying classification of high-risk AI systems, considers the changes prompted by the release of ChatGPT and examines how LLMs appear to have altered policymakers’ conceptions of the risks presented by AI. Finally, we present a framework for understanding how the security and safety risks posed by LLMs fit within the larger context of risks presented by AI and current efforts to formulate a regulatory framework for AI. The second part of the paper considers the similarities and differences between the proposed AI Act and GDPR in terms of (1) organizations being regulated, or scope, (2) reliance on organizations’ self-assessment of potential risks, or degree of self-regulation, (3) penalties, and (4) technical knowledge required for effective enforcement, or complexity. For each of these areas, we consider how regulators scoped or implemented GDPR to make it manageable, enforceable, meaningful, and consistent across a wide range of organizations handling many different kinds of data as well as the extent to which they were successful in doing so. We then examine different ways in which those same approaches may or may not be applicable to the AI Act and the ways in which AI may prove more difficult to regulate than issues of data protection and privacy covered by GDPR. We also look at the ways in which AI may make it more difficult to enforce and comply with GDPR since the continued evolution of AI technologies may create cybersecurity tools and threats that will impact the efficacy of GDPR and privacy policies. This section argues that the extent to which the proposed AI Act relies on self-regulation and the technical complexity of enforcement are likely to pose significant challenges to enforcement based on the implementation of the most technologically and self-regulation-focused elements of GDPR

Surface and volume effects in the photoabsorption of nuclei

Recent experimental results for meson photoproduction from nuclei obtained with TAPS at MAMI are analyzed in view of the suppression of the second nucleon resonance region in total photoabsorption. The cross sections can be split into a component from the low density surface region of nuclei and a component which scales more like the nuclear volume. The energy dependence of the surface component is similar to the deuteron cross section, it shows a clear signal for the second resonance peak assigned to the excitation of the P11(1440), D13(1520), and S11(1535). The volume component behaves differently, it is lacking the second resonance peak and shows an enhancement at intermediate photon energies.Comment: accepted for publication in Eur. J. Phys.

Photoproduction of pi0-mesons from nuclei

Photoproduction of neutral pions from nuclei (carbon, calcium, niobium, lead) has been studied for incident photon energies from 200 MeV to 800 MeV with the TAPS detector using the Glasgow photon tagging spectrometer at the Mainz MAMI accelerator. Data were obtained for the inclusive photoproduction of neutral pions and the partial channels of quasifree single pi0, double pi0, and pi0pi+/- photoproduction. They have been analyzed in terms of the in-medium behavior of nucleon resonances and the pion - nucleus interaction. They are compared to earlier measurements from the deuteron and to the predictions of a Boltzmann-Uehling-Uhlenbeck (BUU) transport model for photon induced pion production from nuclei.Comment: 15 pages, 22 figures, accepted for publication in EPJ

Relativistic Diskoseismology. I. Analytical Results for 'Gravity Modes'

We generalize previous calculations to a fully relativistic treatment of adiabatic oscillations which are trapped in the inner regions of accretion disks by non-Newtonian gravitational effects of a black hole. We employ the Kerr geometry within the scalar potential formalism of Ipser and Lindblom, neglecting the gravitational field of the disk. This approach treats perturbations of arbitrary stationary, axisymmetric, perfect fluid models. It is applied here to thin accretion disks. Approximate analytic eigenfunctions and eigenfrequencies are obtained for the most robust and observable class of modes, which corresponds roughly to the gravity (internal) oscillations of stars. The dependence of the oscillation frequencies on the mass and angular momentum of the black hole is exhibited. These trapped modes do not exist in Newtonian gravity, and thus provide a signature and probe of the strong-field structure of black holes. Our predictions are relevant to observations which could detect modulation of the X-ray luminosity from stellar mass black holes in our galaxy and the UV and optical luminosity from supermassive black holes in active galactic nuclei.Comment: 31 pages, 6 figures, uses style file aaspp4.sty, prepared with the AAS LATEX macros v4.0, significant revision of earlier submission to include modes with axial index m>

Mesopore etching under supercritical conditions – A shortcut to hierarchically porous silica monoliths

Hierarchically porous silica monoliths are obtained in the two-step Nakanishi process, where formation of a macro microporous silica gel is followed by widening micropores to mesopores through surface etching. The latter step is carried out through hydrothermal treatment of the gel in alkaline solution and necessitates a lengthy solvent exchange of the aqueous pore fluid before the ripened gel can be dried and calcined into a mechanically stable macro mesoporous monolith. We show that using an ethanol water (95.6/4.4, v/v) azeotrope as supercritical fluid for mesopore etching eliminates the solvent exchange, ripening, and drying steps of the classic route and delivers silica monoliths that can withstand fast heating rates for calcination. The proposed shortcut decreases the overall preparation time from ca. one week to ca. one day. Porosity data show that the alkaline conditions for mesopore etching are crucial to obtain crack-free samples with a narrow mesopore size distribution. Physical reconstruction of selected samples by confocal laser scanning microscopy and subsequent morphological analysis confirms that monoliths prepared via the proposed shortcut possess the high homogeneity of silica skeleton and macropore space that is desirable in adsorbents for flow-through applications

Spectral Function of Quarks in Quark Matter

We investigate the spectral function of light quarks in infinite quark matter using a simple, albeit self-consistent model. The interactions between the quarks are described by the SU(2) Nambu--Jona-Lasinio model. Currently mean field effects are neglected and all calculations are performed in the chirally restored phase at zero temperature. Relations between correlation functions and collision rates are used to calculate the spectral function in an iterative process.Comment: final version, published in PRC; 15 pages, RevTeX
