description: Η Πολιτεία αποτελεί ένα από τα μεγαλύτερα έργα του Πλάτωνα μέσα στο οποίο παρουσιάζονται οι πιο αντιπροσωπευτικές θεωρίες του, όπως για παράδειγμα ο τριμερής διαχωρισμός της ψυχής και η ανάγκη για πολιτικές μεταρρυθμίσεις. Ένα από τα προβλήματα που θα αντιμετωπίσει ένας μελετητής είναι η κατηγοριοποίηση του έργου, δηλαδή αν αποτελεί ένα έργο πολιτικής φιλοσοφίας ή ηθικής. Η παρούσα διπλωματική θα ασχοληθεί με αυτό ακριβώς το ζήτημα. Μετά από μία συνοπτική παρουσίαση του έργου θα παρατεθούν ένα σύνολο από επιχειρήματα που υποστηρίζουν την άποψη ότι πρόκειται για ένα έργο ηθικής φιλοσοφίας. Στη συνέχεια, θα αναλυθούν τα επιχειρήματα της πλευράς που υποστηρίζει ότι αποτελεί ένα έργο πολιτικής φιλοσοφίας. Τέλος, στον επίλογο θα γίνει μία σύγκριση των επιχειρημάτων αυτών, και θα παρουσιαστεί και μία διαφορετική προσέγγιση στην επίλυση του προβλήματος αυτού
description: The Republic is one of the biggest works of Plato, and within it Plato presents some of his most representative theories, such as the tripartite theory of soul and the need for political reforms. One of the problems a researcher will face is the identification of the branch of philosophy this work belongs to, i.e. whether it is a work of political philosophy or ethics. This master thesis will study this exact matter. After a short presentation of the Republic, a number of arguments will be presented that support the view that it is a work of ethics. In the next section, the arguments of those who debate that the Republic is a work of political philosophy will be presented. Finally, a comparison of those arguments will be displayed in the conclusion, and a different approach to the solution of this problem will be provided
The White Dwarf in AE Aqr Brakes Harder

description: Taking advantage of the very precise de Jager et al. optical white dwarf orbit and spin ephemerides; ASCA, XMMN, and Chandra X-ray observations spread over 10 yrs; and a cumulative 27 yr baseline, we have found that in recent years the white dwarf in AE Aqr is spinning down at a rate that is slightly faster than predicted by the de Jager et al. spin ephemeris. At the present time, the observed period evolution is consistent with either a cubic term in the spin ephemeris with Pdouble_dot = 3.46(56)E-19 per d, which is inconsistent in sign and magnitude with magnetic-dipole radiation losses, or an additional quadratic term with Pdot = 2.0(1.0)E-15 d/d, which is consistent with a modest increase in the accretion torques spinning down the white dwarf. Regular monitoring, in the optical, ultraviolet, and/or X-rays, is required to track the evolution of the spin period of the white dwarf in AE Aqr.

pysradb: A Python package to query next-generation sequencing metadata and data from NCBI Sequence Read Archive
Creators: name: Saket Choudhary
Publisher: name: F1000 Research Limited
Year: 2019

description: The NCBI Sequence Read Archive (SRA) is the primary archive of next-generation sequencing datasets. SRA makes metadata and raw sequencing data available to the research community to encourage reproducibility and to provide avenues for testing novel hypotheses on publicly available data. However, methods to programmatically access this data are limited. We introduce the Python package, pysradb, which provides a collection of command-line methods to query and download metadata and data from SRA, utilizing the curated metadata database available through the SRAdb project. We demonstrate the utility of pysradb on multiple use cases for searching and downloading SRA datasets. It is available freely at https://github.com/saketkc/pysradb.

description: The present work is devoted to the investigation of the interaction between vortices (topological defects) and site-impurities (structural defects) in the 2D XY model and its influence on the well-known properties of the pure system. The main goal is a theoretical description of the Berezinskii-Kosterlitz-Thouless (BKT) temperature reduction by quenched non-magnetic impurities, based on the vacancy-vortex interactions and the vortex-pair dissociation mechanism of the transition. The non-magnetic impurity interaction with a system of vortices can be found either from the phenomenological theory of topological defects or from the Villain model. We take both paths and compare the results obtained. Our prediction for the BKT temperature reduction is confirmed by the available Monte Carlo data.

description: Η παρούσα μελέτη αφορά στην ανάδειξη της ταυτότητας του έλληνα μετανάστη στη Γερμανία μέσα από λογοτεχνικά έργα της ελληνικής και γερμανικής λογοτεχνίας. Προσεγγίζεται σε αυτήν η έννοια της ταυτότητας σε διάφορες διαστάσεις της, ατομική, κοινωνική, εθνική, πολιτισμική, για να υπάρξει έπειτα ιδιαίτερη εστίαση στην ταυτότητα του μετανάστη. Δίνεται το ιστορικό της μετανάστευσης των Ελλήνων στη Γερμανία, ιδιαίτερα κατά τη δεκαετία του 1960 και οι ιδιαίτερες συνθήκες κάτω από τις οποίες έγινε η μετανάστευση αυτή. Ακριβώς αυτές συνθήκες συντέλεσαν και στην εμφάνιση μιας ιδιαίτερης και σχετικής με το θέμα λογοτεχνίας, κυρίως στον ελλαδικό χώρο και σε πολύ μικρό βαθμό στο γερμανικό, πολλές φορές, ειδικά στη δεύτερη περίπτωση, με τη μορφή γερμανόφωνης λογοτεχνίας Ελλήνων. Σε αυτό το πλαίσιο αναλύονται κάποιες πλευρές της Θεωρίας της Λογοτεχνίας και γίνεται ακολούθως υποκειμενική ανάλυση των αφηγήσεων έξι λογοτεχνικών βιβλίων, έργων συγγραφέων που είτε είναι Έλληνες μετανάστες πρώτης ή δεύτερης γενιάς είτε Γερμανοί, που βίωσαν αυτές τις ιδιάζουσες συνθήκες της μετανάστευσης, μέσα από τη δική τους κάθε φορά οπτική. Από αυτήν την ανάλυση προκύπτουν συμπεράσματα που αφορούν στην ταυτότητα του Έλληνα μετανάστη στη Γερμανία στις διάφορες εκφάνσεις της αλλά και στην ατομική ταυτότητα των ηρώων των εξεταζόμενων κειμένων
description: The present study is dealing with the emergence of the identity of Greek immigrants in Germany, through literature works from both Greek and German writers. The notion of identity is approached in its variety of dimensions, personal, national, social and cultural with a particular focus in that of the Greek immigrant. The historical context of the immigration wave from Greece to Germany especially in the 60’s is unfolded with an emphasis in the events that took place. It was those conditions that contributed to the emergence of this particular literature genre especially in Greece and in a much lesser extend in Germany, with works from Greeks written in the German language. Drawing from the paradigm of discourse theory, we analyze six novels, works of first or second generation Greek immigrants. People, who experienced the particular conditions of the immigration, and described it through their own lens. Based on this analysis, we are able to make significant assumptions about the identity of the Greek immigrants in Germany and how it intertwines with the individual identities of the novels’ characters

The implementation of sequential and parallel algorithms for solving almost block bidiagonal systems
Creators: name: Song, Yan
Publisher: name: University of British Columbia
Year: 2008

description: In this thesis, we mainly concentrate on the implementation of sequential and parallel algorithms for solving block bidiagonal linear system arising from the discretization of boundary value problems for linear ordinary differential equations. It consists of two parts. In Part I, several sequential algorithms, the Alternate Row and Column Pivoting Algorithm, the Structured QR Algorithm, the Structured LU Algorithm and the Least Square Algorithm, are implemented and some stability issues of these algorithms are considered. Numerical results are presented. In Part II, the corresponding parallel algorithms, except the Parallel Alternate Row and Column Pivoting Algorithm, are implemented on INMOS T800 Transputers, a microcomputer with multi processors.To abstract the application from the system function calls, we use a template based on a simple software system with master-slave technique as the interface with the application. The description of those parallel algorithms and numerical results are presented. Only the case with separate boundary conditions is considered here. Among all the sequential algorithms, we can say that the Alternate Row and Column Pivoting Algorithm is the most efficient algorithm with no fill-ins, while the Structured QR Algorithm is the most stable algorithm. Though the Structured LU Algorithm is much faster than Structured QR Algorithm in the sequential case if the block size is greater than 3, the absolute run times of both parallel algorithms are almost the same because the Parallel Structured QR Algorithm obtains better speedup.

description: Various planning-based know-how logics have been studied in the recent literature. In this paper, we use such a logic to do know-how-based planning via model checking. In particular, we can handle the higher-order epistemic planning involving know-how formulas as the goal, e.g., find a plan to make sure p such that the adversary does not know how to make p false in the future. We give a PTIME algorithm for the model checking problem over finite epistemic transition systems and axiomatize the logic under the assumption of perfect recall.

description: Sentiment orientation is the field of Natural Processing Language (NLP) studying the identification of the sentiment in text. This master thesis addresses the problem of predicting the sentiment of messages from Twitter using traditional Machine Learning Techniques (ML) and Neural Nets (NNs) applying word embeddings produced by Neural Language Models (NLMs). At first, the terms Sentiment Orien-tation and Sentiment Analysis are defined. Later, the traditional machine learning techniques are pre-sented alongside with their algorithms. Special attention is given to the function of NNs and their ar-chitectures. Later, the importance of encoding the text into vectors is analysed using different tech-niques. There is a history flashback related to the creation of the vector representations using NNs. Furthermore, the architecture and the system of NLMs is demonstrated which produce state-of-the-art word embeddings in many fields of NLP using NNs. The methodology and the used neural net archi-tecture is described in order to create each aforementioned word embedding. Finally, the results are displayed after the application of traditional Machine Learning Techniques and NNs with the different word embeddings in two datasets using the metrics F1 and Accuracy

telemedicine abortion

description: The Covid-19 pandemic prompted the United Kingdom’s Royal College of Obstetricians and Gynaecologists to publish guidelines to safeguard abortion care in the UK. These new guidelines allowed for the delivery of medical abortion via telemedicine for people with pregnancies up to 10 weeks’ gestation. The telemedicine model does not require ultrasound scans unless there are reported symptoms. Based on over 52,000 reports of abortion during the study period, the authors, led by PRC faculty research associate Abigail Aiken, found that telemedicine medical abortion without ultrasound is safe, effective and improves access. They argue that no-test telemedicine should become routine in the provision of abortion care.

description: Purpose
Given the surge in foreign direct investment (FDI) in emerging economies (EEs) during the past four decades, inward FDI (IFDI) has spawned a rich, scholarly conversation on the topic. This paper aims to review the literature regarding EE IFDI determinants and the impact of IFDI on those economies. It also aims to provide some future research directions.

Design/methodology/approach
A systematic review with thematic analysis of 372 articles on the topic, published between 1991 and 2021, is undertaken. In addition to using the relevant keywords, the snowballing approach was used to manually track the literature.

Findings
This review highlights EE IFDI determinants such as institutional quality, corruption and intellectual property rights, regional trade agreements and distances, formal and informal institutions and their interactions, national and subnational diversity and policy expectations. Further, IFDI impacts EEs both at macro- and micro-levels. This review also indicates a substantial increase in research during the period 2000 to 2010 and a decline thereafter; it also indicates Africa and Latin America being under-researched, with a focus on Africa recently increasing.

Research limitations/implications
Rich research opportunities exist in examining the mechanisms (mediators) and conditions (moderators) that influence relationships between the antecedents of IFDI and their outcomes. Further opportunities exist in examining the role of the context and in undertaking a multilevel analysis.

Originality/value
This review provides an understanding of what influences multinational enterprises’ FDI to EEs and how it impacts those economies. It also raises potential future research questions. It provides a holistic understanding of the chosen scope and domain.
A model for exchange-biased asymmetric giant magneto-impedance in amorphous wires

description: A model describing the exchange-biased asymmetric giant magneto-impedance in Joule-heated amorphous wires is proposed. It is assumed that the Joule heating results in the formation of a surface hard magnetic crystalline layer, and the asymmetric giant magneto-impedance is related to the exchange coupling between the amorphous and crystalline phases. The coupling between the surface layer and the amorphous bulk is described in terms of an effective bias field. The model is based on a simultaneous solution of linearizied Maxwell equations and the Landau-Lifshitz equation. The calculated field and frequency dependences of the wire impedance are in a qualitative agreement with results of the experimental study of the asymmetric giant magneto-impedance in Joule-heated Co-based amorphous wires.

description: We offer a very simple model of how collective memory may form. Agents keep signalling within neighbourhoods, and depending on how many support each signal, some signals "win" in that neighbourhood. By agents interacting between different neighbourhoods, 'influence' spreads and sometimes, a collective signal emerges. We propose a logic in which we can reason about such emergence of memory and present preliminary technical results on the logic.

description: We present a detailed analysis of a large spectroscopic and photometric sample of DZ white dwarfs based on our latest model atmosphere calculations. We revise the atmospheric parameters of the trigonometric parallax sample of Bergeron, Leggett, & Ruiz (12 stars) and analyze 147 new DZ white dwarfs discovered in the Sloan Digital Sky Survey. The inclusion of metals and hydrogen in our model atmosphere calculations leads to different atmospheric parameters than those derived from pure helium models. Calcium abundances are found in the range from log (Ca/He) = -12 to -8. We also find that fits of the coolest objects show peculiarities, suggesting that our physical models may not correctly describe the conditions of high atmospheric pressure encountered in the coolest DZ stars. We find that the mean mass of the 11 DZ stars with trigonometric parallaxes, = 0.63 Mo, is significantly lower than that obtained from pure helium models, = 0.78 Mo, and in much better agreement with the mean mass of other types of white dwarfs. We determine hydrogen abundances for 27% of the DZ stars in our sample, while only upper limits are obtained for objects with low signal-to-noise ratio spectroscopic data. We confirm with a high level of confidence that the accretion rate of hydrogen is at least two orders of magnitude smaller than that of metals (and up to five in some cases) to be compatible with the observations. We find a correlation between the hydrogen abundance and the effective temperature, suggesting for the first time empirical evidence of a lower temperature boundary for the hydrogen screening mechanism. Finally, we speculate on the possibility that the DZA white dwarfs could be the result of the convective mixing of thin hydrogen-rich atmospheres with the underlying helium convection zone.

Έχει στόχο να αναδείξει τα προβλήματα που ανακύπτουν κατά την είσοδο και παραμονή τους στο Νοσοκομείο, το μη συντονισμό των εμπλεκόμενων υπηρεσιών (κοινωνικών, αστυνομικών, δικαστικών), αλλά και τη στάση του προσωπικού σχετικά με την υποδοχή και διαχείριση τους. Το δείγμα της έρευνας αποτέλεσαν 68 ανήλικοι, από τους οποίους οι 53 εισήχθησαν κατόπιν εισαγγελικής εντολής, ενώ για τους 15 ζητήθηκε η συνδρομή της εισαγγελίας, όταν διαπιστώθηκε ότι η ζωή τους διέτρεχε κίνδυνο. Στην έρευνα χρησιμοποιήθηκε ερωτηματολόγιο ερωτήσεων κλειστού τύπου πολλαπλών για την αναλυτική αποτύπωση των παραπάνω περιστατικών. Πιο συγκεκριμένα, το ερωτηματολόγιο αναφερόταν στα δημογραφικά χαρακτηριστικά των ανηλίκων, την παραπομπή και διαχείρισή τους, το λόγο της εισαγγελικής εντολής και την έκβαση.

description: The research concerns a retrospective study of children who were admitted after a public prosecutor’s order at the AHEPA Pediatric Clinic in the period 2009-2018. Its aim is to highlight the problems that arise when entering and staying at the Hospital, the non-coordinated operation of the services involved (social, police, judicial), as well as the staff attitudes about reception and management. The sample consists of 68 minors, of whom 53 were admitted following a public prosecutor’s order. For the remaining 15, the prosecutor’s assistance was called for, when their life was found to be at risk. A multiple-type closed questionnaire was used for the detailed description of the above incidents. In particular, the questionnaire referred to the demographic characteristics of the minors, their referral and management, the reason for the prosecution and the outcome. The data, which were statistically analyzed through the IBMSPSS 23 software, demonstrated the need for a number of additional measures to improve the coordination between the involved actors in order to avoid the minors’ secondary traumatization and, ultimately, ensure if possible their stay in their family

description: Influenza A virus (IAV) Matrix 2 protein (M2) is an ion channel, required for efficient viral entry and egress. M2 interacts with the small ubiquitin-like LC3 protein through a cytoplasmic C-terminal LC3-interacting region (LIR). Here, we report that M2 is cleaved by caspases, abolishing the M2-LC3 interaction. A crystal structure of the M2 LIR in complex with LC3 indicates the caspase cleavage tetrapeptide motif (82SAVD85) is an unstructured linear motif that does not overlap with the LIR. IAV mutant expressing a permanently truncated M2, mimicking caspase cleavage, exhibit defects in M2 plasma membrane transport, viral filament formation, and virion production. Our results reveal a dynamic regulation of the M2-LC3 interaction by caspases. This highlights the role of host proteases in regulating IAV exit, relating virion production with host cell state.

Measurements on fourteen common CPAs including alcohols (glycerol, methanol, isopropanol), sugars (sucrose, xylitol, dextrose, trehalose), PEGs (ethylene glycol, PEG 200, PEG 2 000, PEG 20 000), glycols (DMSO, MPD), and salt (NaCl) were performed for volumes ranging over four orders of magnitude from ~nL to 20 mkL, and covering the range of interest in protein crystallography. X-ray diffraction measurements on aqueous glycerol mixtures confirm that the polycrystalline-to-vitreous transition occurs within a span of less than 2% w/v in CPA concentration, and that the form of polycrystalline ice (hexagonal or cubic) depends on CPA concentration and cooling rate. For most of the studied cryoprotectants, the critical concentration decreases strongly with volume in the range from ~5 mkL to ~0.1 mkL, typically by a factor of two. By combining measurements of the critical concentration versus volume with cooling time versus volume, we obtain the function of greatest intrinsic physical interest: the critical CPA concentration versus cooling rate during flash cooling. These results provide a basis for more rational design of cryoprotective protocols, and should yield insight into the physics of glass formation in aqueous mixtures.

description: In this paper, we investigate the photon sphere, shadow radius and quasinormal modes of a four-dimensional charged Einstein-Gauss-Bonnet black hole. The perturbation of a massless scalar field in the black hole's background is adopted. The quasinormal modes are gotten by the $6th$ order WKB approximation approach and shadow radius, respectively. When the value of the Gauss-Bonnet coupling constant increase, the values of the real parts of the quasinormal modes increase and those of the imaginary parts decrease. The coincidence degrees of quasinormal modes derived by the two approaches increases with the increase of the values of the Gauss-Bonnet coupling constant and multiple number. It shows the correspondence between the shadow and test field in the four-dimensional Einstein-Gauss-Bonnet-Maxwell gravity. The radii of the photon sphere and shadow increase with the decrease of the Gauss-Bonnet coupling constant.

description: A common feature of all Quantum Gravity (QG) phenomenology approaches is to consider a modification of the mass shell condition of the relativistic particle to take into account quantum gravitational effects. The framework for such approaches is therefore usually set up in the cotangent bundle (phase space). However it was recently proposed that this phenomenology could be associated with an energy dependent geometry that has been coined ``rainbow metric". We show here that the latter actually corresponds to a Finsler Geometry, the natural generalization of Riemannian Geometry. We provide in this way a new and rigorous framework to study the geometrical structure possibly arising in the semiclassical regime of QG. We further investigate the symmetries in this new context and discuss their role in alternative scenarios like Lorentz violation in emergent spacetimes or Deformed Special Relativity-like models.

Publisher: name: Imperial College London
Year: 2020

description: Problem Domain: Type II diabetes (T2D) is a severe chronic metabolic disorder. The Kingdom of Saudi Arabia (KSA) currently suffers from high rates of undiagnosed T2D. In response, the KSA Ministry of Health (MoH) implemented the National Diabetes Prevention and Control Program (NDPCP) as a way to promote the diagnosis and early intervention for T2D. This project aimed to assess the feasibility of using Twitter, a highly-used social media platform in KSA, to promote diabetic screening among persons at risk of developing T2D in KSA. The objectives of this research were to: 1) develop a targeted social media model for the “Do not Wait for Diabetes” (DNWD) Campaign using Twitter, 2) compare the screening frequencies for T2D before and after the implementation of the DNWD Twitter Campaign, 3) measure users’ engagement and satisfaction with the DNWD Twitter Campaign, and 4) explore stakeholders’ views on the DNWD Twitter Campaign and its wider implementation and sustainability. Methodology: To achieve the objectives, a Twitter social media campaign was implemented using the MoH NDPCP Twitter account, and three substudies performed. Frequencies of T2D referrals at two MoH clinical locations, results from a Twitter user survey, and qualitative data from interviewing clinical and governmental stakeholders were analyzed to provide insight on the impact of the Twitter social media campaign. Results: The social media campaign was implemented from November 2017 through July 2018. Referral data were not helpful in providing insight on campaign impact, but survey data were. Of the approximately 800 Twitter users surveyed who were following the NDPCP Twitter account, 95% of respondents reported getting screened for T2D over the period of the campaign, and of those, 87% said they were Page 7 motivated by the tweets from the campaign. Over 90% of respondents reported satisfaction with various dimensions of the tweets. Interview results revealed that stakeholders felt that the campaign was realistic and sustainable if budgeted as a component of the overall public health campaign organized by the MoH. Conclusion: This project demonstrated that social media can be used to enhance the reach of an existing government-sponsored T2D awareness public health campaign. Future social media health education awareness projects can use this example as a prototype for applying social media to public health campaigns aimed at other clinical areas and populations.

description: The minimal gauged $U(1)_{L_μ-L_τ}$ model has long been known to be able to explain the tension between the theoretical and experimental values of the muon magnetic moment. It has been explored and tested extensively, pushing the viable parameter space into a very tight corner. Further, embedding the $U(1)_{L_μ-L_τ}$ model in a supersymmetric (SUSY) framework has been shown to relax some of these constraints and has recently been shown to explain the electron anomalous magnetic moment as well. In this model, the logarithm of the mass ratio of third to second generation (s)leptons control the non-negligible kinetic mixing and may crucially alter many of the constraints. We confront both the non-SUSY and SUSY versions of this class of models with the CsI(2017), the recently released CENNS10 data from the liquid Argon detector as well as the updated CsI(2020) data of the COHERENT experiment. We use the recoil energy and timing binned data from CsI(2017) and the energy, time, and Pulse Shape Discriminator binned data from CENNS10 to find estimates for the model parameters in a likelihood maximization test. We also show updated exclusions using all of the above data from the COHERENT Collaboration, as well as projected exclusions from the ongoing Coherent CAPTAIN-Mills experiment. The $(g-2)_μ$ favored values of the $U(1)_{L_μ-L_τ}$ gauge coupling that are still unconstrained overlap with the estimates from COHERENT data within $1σ$. The combined COHERENT data is found to prefer the presence of the $U(1)_{L_μ-L_τ}$ gauge boson over the Standard Model at $\sim1.4σ$. The global minima of a chi-square deviation function using CsI(2020) as well as CENNS10 total counts has significant overlap with the $(g-2)_μ$ favored parameter space in the context of the SUSY and non-SUSY $L_μ-L_τ$ models with a mediator mass in the $20-100$ MeV range.

description: The comparison theorem for skew Brownian motions is proved. As the corollary we get the estimate on ${\Cal L}_1-$distance between two skew Brownian motions started from different points. Using this result we prove the continuous dependence on starting point of one class of generalized diffusion processes constructed as the strong solution to an SDE.
Ultra-Precise relative Astrometry with next-generation VLBI: Methods, Opportunities and Requirements
Creators: name: Rioja, Maria J.
Publisher: name: Zenodo

description: We are at the cusp of a generational shift in the power of radio interferometers, with exciting next-generation instruments, such as SKA, ngVLA and upgraded EHT, that are coming online. Next-generation VLBI observations bring a potential order-of-magnitude improvements in sensitivity and in astrometric performance, provided that the requirements for optimum calibration methods and usability are not designed out. We have been exploring the implications for astrometry of these new instruments, as sensitivity alone will not improve over the current astrometric limits - being systematic and not driven by thermal noise. Thus using traditional phase-referencing techniques will not be able to significantly overcome the current astrometric accuracy nor extend the moderate range of operational frequencies. 

The developments that drive forward the field of ultra-precise astrometry constitute a very active field of research. Next-generation methods such as Source-Frequency-Phase-Referencing and/or MultiView, combined with next-generation technology, offer an order-of-magnitude increase both in accuracy and in the range of operating frequencies across the radio spectrum, for both ground and space-VLBI domains.  In this talk I will report on the fundamentals, potential and recent on-going steps to confirm that these new methods will deliver on their promise and to ensure that any technological requirements are not designed out from the next-generation instruments. We foresee that the combination of the next-generation developments (on instruments, methods and technology) will have the greatest impact in the compilation of large and unbiased ultra-precise astrometric surveys, compared to current instruments, expanding the role of VLBI into new areas of research.

description: The formalization of action and obligation using logic languages is a topic of increasing relevance in the field of ethics for AI. Having an expressive syntactic and semantic framework to reason about agents' decisions in moral situations allows for unequivocal representations of components of behavior that are relevant when assigning blame (or praise) of outcomes to said agents. Two very important components of behavior in this respect are belief and belief-based action. In this work we present a logic of doxastic oughts by extending epistemic deontic stit theory with beliefs. On one hand, the semantics for formulas involving belief operators is based on probability measures. On the other, the semantics for doxastic oughts relies on a notion of optimality, and the underlying choice rule is maximization of expected utility. We introduce an axiom system for the resulting logic, and we address its soundness, completeness, and decidability results. These results are significant in the line of research that intends to use proof systems of epistemic, doxastic, and deontic logics to help in the testing of ethical behavior of AI through theorem-proving and model-checking.

description: We present arguments for the existence of charged, rotating black holes in $d=2N+1$ dimensions, with $d\geq 5$ with a positive cosmological constant. These solutions posses both, a regular horizon and a cosmological horizon of spherical topology and have $N$ equal-magnitude angular momenta. They approach asymptotically the de Sitter spacetime background. The counterpart equations for $d=2N+2$ are investigated, by assuming that the fields are independant of the extra dimension $y$, leading to black strings solutions. These solutions are regular at the event horizon. The asymptotic form of the metric is not the de Sitter form and exhibit a naked singularity at finite proper distance.

description: A partir del “Mapa de Confiabilidad” elaborado por María Page, Pedro Antenucci y Marcelo Leiras (2019) y los resultados de la misión de observación electoral realizada por la Defensoría del Pueblo de la Ciudad Autónoma de Buenos Aires durante el proceso electoral 2019 en la Ciudad de Buenos Aires, se presenta un análisis forense de la integridad de las elecciones generales 2019. Para ello se trabajó con los resultados finales de las actas de las mesas de electores nacionales distribuidas en los establecimientos de la Ciudad, las mesas de personas privadas de la libertad y de argentinos/as residentes en el exterior con domicilio en la Ciudad, y finalmente, los resultados del voto de los/as agente de las fuerzas de seguridad que cumplieron funciones durante la jornada electoral. Primeramente, se introducen las particularidades normativas en materia electoral que rigen en la Ciudad y un breve análisis del voto en el exterior, de las personas privadas de la libertad y de las fuerzas de seguridad. Luego, se realiza un análisis en profundidad de la integridad del registro y conteo de los votos en las mesas de electores nacionales. Para ello, primero se presenta la distribución geográfica de electores/as en la Ciudad y los niveles de participación electoral; para después, analizar la integridad de los resultados a partir de ciertos indicadores como son: el comportamiento del voto en blanco y voto nulo; análisis del último dígito y conteo de 0 y 5; consistencia de resultados mediante la correlación entre participación y desempeño de la lista ganadora y la correlación entre el voto en blanco y el margen de victoria; densidad de la distribución de los votos; e indicadores controlados por factores geográficos. Los resultados de todos los indicadores son consistentes y se ubican dentro de lo esperado por la teoría, por lo que no se encuentran indicios de irregularidades o manipulación de las actas donde se registran los resultados de las mesas; ni problemas sistemáticos de administración electoral. Sin embargo, la observación electoral permitió detectar ciertos problemas de gestión electoral respecto al voto de las personas privadas de la libertad: falta de información y capacitación por parte de las autoridades de mesa y electores/as; escasez de boletas e irregularidades con los documentos de identidad. Estos problemas impiden el ejercicio pleno de los derechos políticos y electorales de esta población, y deberán ser atendidos por la autoridad electoral competentes para futuras elecciones.
