description: In this paper we present new photometric and radial velocity data for the PMS $δ$ Sct star H254, member of the young cluster IC 348. Photometric V,R$_C$,I$_C$ light curves were obtained at the Loiano and Asiago telescopes. The radial velocity data was acquired by means of the SARG@TNG spectrograph. High-resolution spectroscopy allowed us to derive precise stellar parameters and the chemical composition of the star, obtaining: T$_{\rm eff}$\,=\,6750\,$\pm$\,150 K; $\log g$\,=\,4.1\,$\pm$\,0.4 dex; [Fe/H]=-0.07$\pm$0.12 dex. Photometric and spectroscopic data were used to estimate the total absorption in the $V$ band A$_{\rm V}$=2.06$\pm$0.05 mag, in agreement with previous estimates. We adopted the technique of the difference in phase and amplitude between different photometric bands and radial velocities to verify that H254 is (definitely) pulsating in a radial mode. This occurrence allowed us to apply the CORS realization of the Baade--Wesselink method to obtain a value for the linear radius of H254 equal to 3.3$\pm$0.7 $R_\odot$. This result was used in conjunction with photometry and effective temperature to derive a distance estimate of 273$\pm$23 pc for H254, and, in turn for IC 348, the host cluster. This value is in agreement within the errors with the results derived from several past determinations and the evaluation obtained through the Hipparcos parallaxes. Finally, we derived the luminosity of H254 and studied its position in the Hertzsprung--Russell diagram. From this analysis it results that this $δ$--Scuti occupies a position close to the red edge of the instability strip, pulsates in the fundamental mode, has a mass of about 2.2 $M_\odot$ and an age of 5$\pm$1 Myr, older than previous estimates.

description: Let $W_{g,n}$ be the correlators computed by Topological Recursion for some given spectral curve $(x,y)$ and $W^\vee_{g,n}$ for $(y,x)$, where the role of $x,y$ is inverted. These two sets of correlators $W_{g,n}$ and $W^\vee_{g,n}$ are related by the $x$-$y$ symplectic transformation. Bychkov, Dunin-Barkowski, Kazarian and Shadrin computed a functional relation between two slightly different sets of correlators. Together with Alexandrov, they proved that their functional relation is indeed the $x$-$y$ symplectic transformation in Topological Recursion. This article provides a fairly simple formula directly between $W_{g,n}$ and $W^\vee_{g,n}$ which holds by their theorem for meromorphic $x$ and $y$ with simple and distinct ramification points. Due to the recent connection between free probability and fully simple vs ordinary maps, we conclude a simplified moment-cumulant relation for moments and higher order free cumulants.

Hard to Track Objects with Irregular Motions and Similar Appearances? Make It Easier by Buffering the Matching Space

description: We propose a Cascaded Buffered IoU (C-BIoU) tracker to track multiple objects that have irregular motions and indistinguishable appearances. When appearance features are unreliable and geometric features are confused by irregular motions, applying conventional Multiple Object Tracking (MOT) methods may generate unsatisfactory results. To address this issue, our C-BIoU tracker adds buffers to expand the matching space of detections and tracks, which mitigates the effect of irregular motions in two aspects: one is to directly match identical but non-overlapping detections and tracks in adjacent frames, and the other is to compensate for the motion estimation bias in the matching space. In addition, to reduce the risk of overexpansion of the matching space, cascaded matching is employed: first matching alive tracks and detections with a small buffer, and then matching unmatched tracks and detections with a large buffer. Despite its simplicity, our C-BIoU tracker works surprisingly well and achieves state-of-the-art results on MOT datasets that focus on irregular motions and indistinguishable appearances. Moreover, the C-BIoU tracker is the dominant component for our 2-nd place solution in the CVPR'22 SoccerNet MOT and ECCV'22 MOTComplex DanceTrack challenges. Finally, we analyze the limitation of our C-BIoU tracker in ablation studies and discuss its application scope.

Management by Accounting: An Ethnography of Agencification

description: This study outlines the role of accounting in an agencification context. It explores the everyday accounting in semi-autonomous agencies by observing micro-processes of agencification, i.e. the use of semi-autonomous agencies to deliver public services.To fully grasp how the practice unfolded in real time, ethnographic fieldwork was carried out in five agencies and one supervisory ministry in Indonesia. Participant observation was used by witnessing the ongoing processes, events, situated moments, and routines either at the collective or individual level. Data collection was supplemented by semi-structured interviews, documentary analysis, and a survey.Using practice-based views, the study unveils how everyday accountings are consequential in structuring the contours of agencification. Accounting practices constitute agencification by shaping organisational patterns and relations characterised by a high circulation of numbers and performance metrics. They contribute to the production and reproduction of agencification by actively developing its concepts, adoption, and implementation using numbers and calculative devices. Meanwhile, agencification emerges through and is constituted by the aggregation of interrelated accounting practices. It gives way to accounting-led agencies by providing more space for calculative initiatives performed by agency managers and staff to conduct and conceive their everyday tasks with reference to accounting, and use accounting to shape and pursue agencification objectives.The study suggests that practice theory enhances scholarly understanding on agencification by providing a rich analytical framework to uncover why and how accounting practices are organised. This view provides a way of understanding the various activities involved in agencification in relation to each other as several bundles of accounting activity. This further demonstrates how accounting can be studied and viewed as a social practice.

description: We show that amphiphilic and colloidal systems with competing interactions can be described by the same Landau-Brazovskii functional. The functional is obtained by a systematic coarse-graining procedure applied tosystems with isotropic interaction potentials. Microscopic expressions for the coefficients in the functional are derived. We propose simple criteria to distinguish the effective interparticle potentials that can lead to macro- or microsegregation. Our considerations concern also charged globular proteins in aqueous solutions and other system with effective short-range attraction long-range repulsion interactions.

description: We present a comprehensive formalism to derive precise expressions for the induced gravity of the braneworld, assuming the dynamics of the Dirac-Nambu-Goto type. The quantum fluctuations of the brane at short distances give rise to divergences, which should be cutoff at the scale of the inverse thickness of the brane. It turns out that the induced-metric formula is converted into an Einstein-like equation via the quantum effects. We determine the coefficients of the induced cosmological and gravity terms, as well as those of the terms including the extrinsic curvature and the normal connection gauge field. The latter is the characteristic of the brane induced gravity theory, distinguished from ordinary none-brane induced gravity.

description: Learning image representations using synthetic data allows training neural networks without some of the concerns associated with real images, such as privacy and bias. Existing work focuses on a handful of curated generative processes which require expert knowledge to design, making it hard to scale up. To overcome this, we propose training with a large dataset of twenty-one thousand programs, each one generating a diverse set of synthetic images. These programs are short code snippets, which are easy to modify and fast to execute using OpenGL. The proposed dataset can be used for both supervised and unsupervised representation learning, and reduces the gap between pre-training with real and procedurally generated images by 38%.

Finally, we study observables and show situations when information of an observable on all intervals of the form $(-\infty,t)$ gives full information about the observable.

description: The cotton warehousing industry was able to hold the line on storage and handling costs in fiscal 1972-73 despite continuing increases in input costs. An increase in the average occupancy level of about 5 percent offset increases in labor costs and increases in capital expenditures. These findings are based on analysis of accounting and other data obtained by mail questionnaire from warehouse and compress facilities. The types of cost given are (1) total cost for all facilities, (2) out-of-pocket cost which excludes depreciation and interest on investment, and (3) projected cost for 1974-75 based on projected disappearance and production levels of 13.0 million and 14.5 million bales, respectively.

description: We identify generic protocols achieving optimal power extraction from a single active particle subject to continuous feedback control under the assumption that its spatial trajectory, but not its instantaneous self-propulsion force, is accessible to direct observation. Our Bayesian approach draws on the Onsager-Machlup path integral formalism and is exemplified in the cases of free run-and-tumble and active Ornstein-Uhlenbeck dynamics in one dimension. Such optimal protocols extract positive work even in models characterised by time-symmetric positional trajectories and thus vanishing informational entropy production rates. We argue that the theoretical bounds derived in this work are those against which the performance of realistic active matter engines should be compared.

description: Inferring interior properties of the Sun from photospheric measurements of the seismic wavefield constitutes the helioseismic inverse problem. Deviations in seismic measurements (such as wave travel times) from their fiducial values estimated for a given model of the solar interior imply that the model is inaccurate. Contemporary inversions in local helioseismology assume that properties of the solar interior are linearly related to measured travel-time deviations. It is widely known, however, that this assumption is invalid for sunspots and active regions, and likely for supergranular flows as well. Here, we introduce nonlinear optimization, executed iteratively, as a means of inverting for the sub-surface structure of large-amplitude perturbations. Defining the penalty functional as the $L_2$ norm of wave travel-time deviations, we compute the the total misfit gradient of this functional with respect to the relevant model parameters %(only sound speed in this case) at each iteration around the corresponding model. The model is successively improved using either steepest descent, conjugate gradient, or quasi-Newton limited-memory BFGS. Performing nonlinear iterations requires privileging pixels (such as those in the near-field of the scatterer), a practice not compliant with the standard assumption of translational invariance. Measurements for these inversions, although similar in principle to those used in time-distance helioseismology, require some retooling. For the sake of simplicity in illustrating the method, we consider a 2-D inverse problem with only a sound-speed perturbation.

Studies on the Smooth and Rough colony morphotypes of Mycobacterium abscessus and their relevance to infection transmission

description: Mycobacterium abscessus (Mab) is an opportunistic pathogen causing severe infections in patients with pre-existing lung disease, notably cystic fibrosis; it was first described in 1953 after isolation from a knee abscess (type strain Mab ATCC 19977). Despite its presumed environmental reservoir, recent evidence indicates patient to patient transmission.Mab is divided into two colony morphotypes, Smooth (S) and Rough (R); the former are associated with high production of glycopeptidolipid (GPL) while the latter have less or no GPL production. S to R transition is based on mutations that eliminate GPL expression. It was hypothesized that Smooth and Rough (R) colony morphotypes reflect differences in cellular hydrophobicity, which in turn affect capacity for aerosol transmission.The properties of type and clinical S and R variants were compared. R strains grew differently in broth and biofilm assays, were consistently more hydrophobic and showed no demonstrable GPLs. However, no differences between S and R were observed in Goldberg drum aerosol or desiccation survival experiments and the ATCC S strain was clearly more resistant to UV exposure. Preparation of ffluc (luciferase)-expressing S and R strains facilitated the desiccation and UV assessments and enabled analysis of hydrophobicity attributable to the variants in mixed cultures. In the latter case, the S strain appeared to be as hydrophobic as the R when the two strains we mixed. It was speculated that redistribution of GPLs might be responsible for this and that this might explain the lack of difference between S and R observed in the aerosol survival experiments. Finally, genome and transcriptome analyses revealed several new and previously recognised polymorphisms associated with R transition.Overall, little support for R strains being adapted to airborne transmission was found and a wider range of genomic targets than previously recognised appeared to underpin S to R transition.

description: Context. Type Ia supernovae (SN Ia) have become an invaluable cosmological tool as their exceptional brightness makes them observable even at very large distances (up to redshifts around z~1). To investigate possible systematic differences between local and distant SN Ia requires detailed models whose synthetic spectra can be compared to observations, and in which the solution of the radiative transfer is a key ingredient. One commonly employed method is the Feautrier scheme, which is generally very robust, but which can yield wrong results under certain conditions that frequently occur in the modelling of supernova ejecta or even in the radiatively driven expanding atmospheres of hot stars. Methods. We use a sophisticated model atmosphere code which takes into account the non-LTE effects and high velocity gradients that strongly affect the physics of SN Ia atmospheres at all wavelengths to simulate the formation of SN Ia spectra by the thousands of strong spectral lines which intricately interact with the "pseudo-continuum" formed entirely by these Doppler-shifted lines themselves. We focus to an investigation of the behavior of the Feautrier scheme under these conditions. Results. Synthetic spectra of SN Ia, a complex product of computer models replicating numerous physical processes that determine the conditions of matter and radiation in the ejecta, are affected by large spatial jumps of the line-dominated opacities and source functions for which the application of even well-established methods may harbor certain pitfalls. We analyze the conditions that can lead to a breakdown of conventional procedures and we derive for the Feautrier radiative transfer solver a modified description which yields more accurate results in the given circumstances.

A Generalized Scalarization Method for Evolutionary Multi-Objective Optimization

Subjects: subject: Neural and Evolutionary Computing (cs.NE)

description: The decomposition-based multi-objective evolutionary algorithm (MOEA/D) transforms a multi-objective optimization problem (MOP) into a set of single-objective subproblems for collaborative optimization. Mismatches between subproblems and solutions can lead to severe performance degradation of MOEA/D. Most existing mismatch coping strategies only work when the $L_{\infty}$ scalarization is used. A mismatch coping strategy that can use any $L_{p}$ scalarization, even when facing MOPs with non-convex Pareto fronts, is of great significance for MOEA/D. This paper uses the global replacement (GR) as the backbone. We analyze how GR can no longer avoid mismatches when $L_{\infty}$ is replaced by another $L_{p}$ with $p\in [1,\infty)$, and find that the $L_p$-based ($1\leq p<\infty$) subproblems having inconsistently large preference regions. When $p$ is set to a small value, some middle subproblems have very small preference regions so that their direction vectors cannot pass through their corresponding preference regions. Therefore, we propose a generalized $L_p$ (G$L_p$) scalarization to ensure that the subproblem's direction vector passes through its preference region. Our theoretical analysis shows that GR can always avoid mismatches when using the G$L_p$ scalarization for any $p\geq 1$. The experimental studies on various MOPs conform to the theoretical analysis.

description: Accreditation is a recognition that an educational activity meets certain standards. The processes for accreditation vary considerably depending on the type of activity, and currently there are differing accreditation systems in place for pharmacy continuing education (CE) across different countries. The aim of this thesis was to research a selection of these systems, which would provide an opportunity to develop a catalogue of accreditation approaches currently in place in a number of different countries, and to explore the possibility of developing a common framework for accreditation of pharmacy CE activities. Such a framework would provide guidance to organisations who need to develop new accreditation systems, it could help towards achieving consistency of approach between organisations, and could also provide a foundation for the development of reciprocal recognition between different jurisdictions relating to accreditation. To that end, accreditation processes from the countries represented by the Global Forum on Quality Assurance of Continuing Education and Continuing Professional Development (GFQAC) were reviewed to explore the themes and patterns in them. Based on this, and other sources as detailed in the thesis, a proposed accreditation framework was developed for CE activities for pharmacists. A Delphi method was used as a consensus building technique with the aim of achieving agreement on the inclusion of items in the framework. Three rounds of the Delphi took place followed by a meeting of the participants. This led to an abbreviated fourth round of the Delphi. Each round of the Delphi assisted in modifying the items in the framework to ensure that it reflected the majority opinions of the GFQAC, as well as best practice. The GFQAC steering group indicated their intention to use the resultant framework as the basis for mutual recognition of accreditation between member countries.

description: We say a class $\mathcal{C}$ of graphs is clean if for every positive integer $t$ there exists a positive integer $w(t)$ such that every graph in $\mathcal{C}$ with treewidth more than $w(t)$ contains an induced subgraph isomorphic to one of the following: the complete graph $K_t$, the complete bipartite graph $K_{t,t}$, a subdivision of the $(t\times t)$-wall or the line graph of a subdivision of the $(t \times t)$-wall. In this paper, we adapt a method due to Lozin and Razgon (building on earlier ideas of Weißauer) to prove that the class of all $H$-free graphs (that is, graphs with no induced subgraph isomorphic to a fixed graph $H$) is clean if and only if $H$ is a forest whose components are subdivided stars. Their method is readily applied to yield the above characterization. However, our main result is much stronger: for every forest $H$ as above, we show that forbidding certain connected graphs containing $H$ as an induced subgraph (rather than $H$ itself) is enough to obtain a clean class of graphs. Along the proof of the latter strengthening, we build on a result of Davies and produce, for every positive integer $η$, a complete description of unavoidable connected induced subgraphs of a connected graph $G$ containing $η$ vertices from a suitably large given set of vertices in $G$. This is of independent interest, and will be used in subsequent papers in this series.

description: Optical metasurfaces performing analog image processing - such as spatial differentiation and edge detection - hold the potential to reduce processing times and power consumption, while avoiding bulky 4F lens systems. However, current designs have been suffering from trade-offs between spatial resolution, throughput, polarization asymmetry, operational bandwidth, and isotropy. Here, we show that dispersion engineering provides an elegant way to design metasurfaces where all these critical metrics are simultaneously optimized. We experimentally demonstrate silicon metasurfaces performing isotropic and dual-polarization edge detection, with numerical apertures above 0.35 and spectral bandwidths of 35 nm around 1500 nm. Moreover, we introduce quantitative metrics to assess the efficiency of these devices. Thanks to the low loss nature and dual-polarization response, our metasurfaces feature large throughput efficiencies, approaching the theoretical maximum for a given NA. Our results pave the way for low-loss, high-efficiency and broadband optical computing and image processing with free-space metasurfaces.

description: Systematic Literature Review: Twenty-six articles investigating the psychological experiences of boarding students were identified and subjected to a systematic analysis. Some studies indicated that boarders experience higher levels of psychological distress (especially soon after boarding transition), experience greater incidences of bullying victimisation, engage in more bullying perpetration, and may be at a higher risk of presenting with eating disorder psychopathology. However, other results reported general parity between wellbeing outcomes for boarders and non-boarders, or modest benefits for boarders measures of wellbeing and personality characteristics. Analysis highlighted the lack of research conducted in UK boarding schools, and the need for further research with extended follow-ups. Limitations of the literature and recommendations for professional practice and future research are discussed. Research Paper: Thematic analysis was used to explore the experiences of male ex-boarders who had identified experiences of difficulties in relationships. Three superordinate themes were presented: Disempowerment depicted how participants felt powerless or controlled by others, and the impact this had in later relationships; Suppressing aspects of self and personality related to how participants described hiding emotions or parts of their personality to ‘get by’, and how these strategies presented in adulthood; and A process of recovery was concerned with how participants sought ways to ‘recover’ from their experiences. Findings were discussed in relation to existing theory and literature and highlighted the importance for educational and care institutions to recognise ideological powers, as well as the use of therapeutic interventions that are underpinned by theories of attachment.
Von Neumann algebra description of inflationary cosmology

description: We study the von Neumann algebra description of the inflationary quasi-de Sitter (dS) space. Unlike perfect dS space, quasi-dS space allows the nonzero energy flux across the horizon, which can be identified with the expectation value of the static time translation generator. Moreover, as a dS isometry associated with the static time translation is spontaneously broken, the fluctuation in time is accumulated, which induces the fluctuation in the energy flux. When the inflationary period is given by $(ε_H H)^{-1}$ where $ε_H$ is the slow-roll parameter measuring the increasing rate of the Hubble radius, both the energy flux and its fluctuation diverge in the $G \to 0$ limit. Taking the fluctuation in the energy flux and that in the observer's energy into account, we argue that the inflationary quasi-dS space is described by Type II$_\infty$ algebra. As the entropy is not bounded from above, this is different from Type II$_1$ description of perfect dS space in which the entropy is maximized by the maximal entanglement. We also show that our result is consistent with the observation that the von Neumann entropy for the density matrix reflecting the fluctuations above is interpreted as the generalized entropy.

description: In this paper, we present the details of the ab initio high-precision configuration interaction and many-body perturbation theory calculations that were used in a previous work to place limits on the dependence of the fine-structure constant, alpha, on the gravitational field of the white-dwarf star G191-B2B. These calculations were combined with laboratory wavelengths and spectra from the Hubble Space Telescope Imaging Spectrograph to obtain limits on the gravitational alpha-dependence using Fe V and Ni V transitions. The uncertainty in these results are dominated by the uncertainty in the laboratory wavelengths. In this work we also present ab initio calculations of the isotopic shifts of the Fe V transitions. We show that improved laboratory spectra will enable determination of the relative isotope abundances in Fe V to an accuracy ~20%. Therefore this work provides a strong motivation for new laboratory measurements.

description: The value of convenience foods sold to the institutional market by 152 food processors totaled over $10 billion in 1973. Most of these sales were among the 14 largest firms reporting. Firms reported that over 6,000 food items were introduced in the last 5 years. The items discontinued in the 5-year period amounted to about 19 percent of those introduced. Frozen heat and serve entrees in standardized portions were seen as the largest growth area for convenience foods in the institutional market.

description: We observe fractional quantum Hall effect (FQHE) at the even-denominator Landau level filling factor $ν=1/2$ in two-dimensional hole systems confined to GaAs quantum wells of width 30 to 50 nm and having bilayer-like charge distributions. The $ν=1/2$ FQHE is stable when the charge distribution is symmetric and only in a range of intermediate densities, qualitatively similar to what is seen in two-dimensional electron systems confined to approximately twice wider GaAs quantum wells. Despite the complexity of the hole Landau level structure, originating from the coexistence and mixing of the heavy- and light-hole states, we find the hole $ν=1/2$ FQHE to be consistent with a two-component, Halperin-Laughlin ($Ψ_{331}$) state.

description: We carry out a numerical calculation of the bispectrum in generalised trajectories of canonical, single--field inflation. The trajectories are generated in the Hamilton-Jacobi (HJ) formalism based on Hubble Slow Roll (HSR) parameters. The calculation allows generally shape and scale dependent bispectra, or dimensionless $f_{NL}$, in the out-of-slow-roll regime. The distributions of $f_{NL}$ for various shapes and HSR proposals are shown as an example of how this procedure can be used within the context of Monte Carlo exploration of inflationary trajectories. We also show how allowing out-of-slow-roll behaviour can lead to a bispectrum that is relatively large for equilateral shapes.

description: The interaction of a single-cycle THz electric field with the topological insulator $\mathrm{MnBi}_2\mathrm{Te}_4$ triggers strongly anharmonic lattice dynamics, promoting fully coherent energy transfer between the otherwise non-interacting Raman-active $E_g$ and infrared (IR)-active $E_u$ phononic modes. Two-dimensional (2D) THz spectroscopy combined with modeling based on the classical equations of motion and symmetry analysis reveals the multi-stage process underlying the excitation of the Raman-active $E_g$ phonon. In this process, the THz electric field first prepares a coherent IR-active $E_u$ phononic state and subsequently interacts with this state to efficiently excite the $E_g$ phonon.

Ceneri mancate: i manoscritti orientali della Biblioteca Nazionale Universitaria di Torino
Creators: name: Boschis, Alessia
Publisher: name: Scrineum Rivista
Year: 2020

description: The article focuses on the oriental manuscripts of the Bibli- oteca Nazionale Universitaria of Turin, their history and vicissitudes. The analysis concerns the formation, enrichment and fortune of the oriental collection over the centuries, with emphasis on the fire that struck the Library on the 25th-26th of January, 1904. The collection mainly consists of Arabic, Persian, Turkish and Hebrew manuscripts. The latter, recently subject of in-depth studies, are not dealt with in this work, so the others are the true protagonists of the survey. The aim of the research is to pro- vide information on the current state of conservation of the manuscripts, also paying attention to the group of manuscripts destroyed by the fire. Following this path, the case of the disappeared Gospel written in Turk- ish by the Capuchin missionary Gabriele of Villa del Foro is indicative. His relationship with the Armenian Mekhitarist Congregation of Venice sheds light on the knowledge and the study of the Armenian language in Italy and Europe during the last decades of the 18th century.

From ‘athleta Dei’ to ‘miles Christi’: The Development of Institutional Support for the Conversion of Northern Europe (800-1200)

description: Between the years 800 and 1200, Latin Christendom underwent a radical period of expansion as new lands and peoples were Christianized. This period included the conversion of Scandinavia to Christianity and the Baltic Crusades against Slavic peoples. The means of converting individuals and groups changed dramatically over the course of these few centuries. This thesis demonstrates that paying close attention to the various forms of institutional support that missionary activities received, as recorded in contemporary accounts from across the period, reveals previously unnoticed factors that made conversion efforts possible. The changing availability of institutional support however, depended directly on the shifting nature of political and ecclesiastical institutions within Latin Christendom, changes which would forever alter the realms beyond its boundaries. In particular, the development of canon law, crusade ideology, sacral kingship, and the increasing power of the state made possible military, financial, and spiritual support of missionaries in ways inconceivable before the year 1100. These developments help explain the transformation of the missionary bishop from wandering preacher to holy warrior, as well as sharpening the contrast between the peaceful conversion of Scandinavia around the year 1000 and the coercive conversion of the Baltic Slavs around the year 1200.
Riordinare, riassegnare, ricostruire. Aspetti del lavoro sui manoscritti greci torinesi

description: The National University Library of Turin holds more than 300 Greek manuscripts. The fire which struck the library in 1904 not only destroyed over a hundred manuscripts, but damaged the surviving ones. A huge restoration campaign took place in the following decades. Nevertheless, many Greek codices are now affected by problems, such as a wrong succession of the leaves, or, in some cases, an incorrect attribu- tion of leaves to the manuscripts. The paper deals with the reconstruction of a manuscript, Taur. C.VII.16, which was heavily damaged by the fire. Whereas it was assumed until now that, due to the damages, the manuscript had completely lost one of the two works it contained (the Homeric Centos of the Empress Eu- docia), the paper aims to demonstrate that this text survived the fire and was restored and – incorrectly – identified as another manuscript, Taur. B.VII.31.
