description: We present an experimental and theoretical study of the optically detected magnetic resonance signals for ensembles of negatively charged nitrogen-vacancy (NV) centers in 13C isotopically enriched single-crystal diamond. We observe four broad transition peaks with superimposed sharp features at zero magnetic field and study their dependence on applied magnetic field. A theoretical model that reproduces all qualitative features of these spectra is developed. Understanding the magnetic-resonance spectra of NV centers in isotopically enriched diamond is important for emerging applications in nuclear magnetic resonance.

Eccentric debris disc morphologies II: Surface brightness variations from overlapping orbits in narrow eccentric discs

description: We present Paper II of the Eccentric Debris Disc Morphologies series to explore the effects that significant free and forced eccentricities have on high-resolution millimetre-wavelength observations of debris discs, motivated by recent ALMA images of HD53143's disc. In this work, we explore the effects of free eccentricity, and by varying disc fractional widths and observational resolutions, show for a range of narrow eccentric discs, orbital overlaps result in dust emission distributions that have either one or two radial peaks at apocentre and/or pericentre. The narrowest discs contain two radial peaks, whereas the broadest discs contain just one radial peak. For fixed eccentricities, as fractional disc widths are increased, we show that these peaks merge first at apocentre (producing apocentre glow), and then at pericentre (producing pericentre glow). Our work thus demonstrates that apocentre/pericentre glows in models with constant free and forced eccentricities can be both width and resolution dependent at millimetre wavelengths, challenging the classical assertion that apocentre/pericentre glows are purely wavelength dependent. We discuss future high-resolution observations that can distinguish between competing interpretations of underlying debris disc eccentricity distributions.

description: Finding the origin of short phrases propagating through the web has been formalized by Leskovec et al. [ACM SIGKDD 2009] as DAG Partitioning: given an arc-weighted directed acyclic graph on $n$ vertices and $m$ arcs, delete arcs with total weight at most $k$ such that each resulting weakly-connected component contains exactly one sink---a vertex without outgoing arcs. DAG Partitioning is NP-hard. We show an algorithm to solve DAG Partitioning in $O(2^k \cdot (n+m))$ time, that is, in linear time for fixed $k$. We complement it with linear-time executable data reduction rules. Our experiments show that, in combination, they can optimally solve DAG Partitioning on simulated citation networks within five minutes for $k\leq190$ and $m$ being $10^7$ and larger. We use our obtained optimal solutions to evaluate the solution quality of Leskovec et al.'s heuristic. We show that Leskovec et al.'s heuristic works optimally on trees and generalize this result by showing that DAG Partitioning is solvable in $2^{O(w^2)}\cdot n$ time if a width-$w$ tree decomposition of the input graph is given. Thus, we improve an algorithm and answer an open question of Alamdari and Mehrabian [WAW 2012]. We complement our algorithms by lower bounds on the running time of exact algorithms and on the effectivity of data reduction.
description: A preliminary version of this article appeared at CIAC'13. Besides providing full proof details, this revised and extended version improves our O(2^k * n^2)-time algorithm to run in O(2^k * (n+m)) time and provides linear-time executable data reduction rules. Moreover, we experimentally evaluated the algorithm and compared it to known heuristics

description: We have found that the 2+2 quadruple star system BU CMi is currently the most compact quadruple system known, with an extremely short outer period of only 121 days. The previous record holder was TIC 219006972 (Kostov et al. 2023), with a period of 168 days. The quadruple nature of BU CMi was established by Volkov et al. (2021), but they misidentified the outer period as 6.6 years. BU CMi contains two eclipsing binaries (EBs), each with a period near 3 days, and a substantial eccentricity of about 0.22. All four stars are within about 0.1 solar mass of 2.4 solar masses. Both binaries exhibit dynamically driven apsidal motion with fairly short apsidal periods of about 30 years, thanks to the short outer orbital period. The outer period of 121 days is found both from the dynamical perturbations, with this period imprinted on the eclipse timing variations (ETV) curve of each EB by the other binary, and by modeling the complex line profiles in a collection of spectra. We find that the three orbital planes are all mutually aligned to within 1 degree, but the overall system has an inclination angle near 83.5 degrees. We utilize a complex spectro-photodynamical analysis to compute and tabulate all the interesting stellar and orbital parameters of the system. Finally, we also find an unexpected dynamical perturbation on a timescale of several years whose origin we explore. This latter effect was misinterpreted by Volkov et al. (2021) and led them to conclude that the outer period was 6.6 years rather than the 121 days that we establish here.

The Gini ($g$) index, giving the overall inequality is the most common one, while the recently introduced Kolkata ($k$) index gives a measure of $1-k$ fraction of population who possess top $k$ fraction of wealth in the society. Here, we show the relationship between the two indices, using both empirical data and analytical estimates. The significance of their relationship has been discussed.

description: Six widely different subthreshold $K^- N$ scattering amplitudes obtained in SU(3) chiral-model EFT approaches by fitting to low-energy and threshold data are employed in optical-potential studies of kaonic atoms. Phenomenological terms representing $K^-$ multinucleon interactions are added to the EFT inspired single-nucleon part of the $K^-$-nucleus optical potential in order to obtain good fits to kaonic-atom strong-interaction level shifts and widths across the periodic table. Introducing as a further constraint the fractions of single-nucleon $K^-$ absorption at rest from old bubble-chamber experiments, it is found that only two of the models considered here reproduce these absorption fractions. Within these two models, the interplay between single-nucleon and multinucleon $K^-$ interactions explains features observed previously with fully phenomenological optical potentials. Radial sensitivities of kaonic atom observables are also re-examined, and remarks are made on the role of `subthreshold kinematics' in absorption at rest calculations.

description: FU Orionis objects (FUors) are eruptive young stars, which exhibit outbursts that last from decades to a century. Due to the duration of their outbursts, and to the fact that only about two dozens of such sources are known, information on the end of their outbursts is limited. Here we analyse follow-up photometry and spectroscopy of Gaia21elv, a young stellar object, which had a several decades long outburst. It was reported as a Gaia science alert due to its recent fading by more than a magnitude. To study the fading of the source and look for signatures characteristic of FUors, we have obtained follow-up near infrared (NIR) spectra using Gemini South/IGRINS, and both optical and NIR spectra using VLT/X-SHOOTER. The spectra at both epochs show typical FUor signatures, such as a triangular shaped $H$-band continuum, absorption-line dominated spectrum, and P Cygni profiles. In addition to the typical FUor signatures, [OI], [FeII], and [SII] were detected, suggesting the presence of a jet or disk wind. Fitting the spectral energy distributions with an accretion disc model suggests a decrease of the accretion rate between the brightest and faintest states. The rapid fading of the source in 2021 was most likely dominated by an increase of circumstellar extinction. The spectroscopy presented here confirms that Gaia21elv is a classical FUor, the third such object discovered among the Gaia science alerts.

description: Last complete novel completed by Charles Dickens and is one of his most sophisticated works, combining savage satire with social analysis. In the opening chapters a body is found in the Thames and identified as that of John Harmon, a young man recently returned to London to receive his inheritance. Were he alive, his father's will would require him to marry Bella Wilfer, a beautiful, mercenary girl whom he had never met. Instead, the money passes to the working-class Boffins, and the effects spread into various corners of London society. Issued monthly from May 1864 to November 1865 in illustrated green paper covers.

description: Η διπλωματική εργασία σχεδιάστηκε με σκοπό να παρουσιάσει τα ψυχολογικά οφέλη των ατόμων με αναπηρία από τη συμμετοχή τους σε αθλητικές δραστηριότητες. Αρχικά, αναλύονται τα είδη αναπηρίας και ταξινομούνται σε κατηγορίες. Περιγράφεται η ψυχολογική κατάσταση των ατόμων που βιώνουν την εκάστοτε αναπηρία αλλά και οι λόγοι για τους οποίους δε λαμβάνουν μέρος σε χώρους άθλησης. Η εργασία στη συνέχεια παρουσιάζει τα αποτελέσματα ερευνών που καταδεικνύουν γιατί η σωματική άσκηση είναι απαραίτητη για τον ψυχισμό των ατόμων με αναπηρίες. Επίσης, σύμφωνα με πρόσφατες μελέτες παρουσιάζονται τα είδη άσκησης που είναι κατάλληλα για άτομα με αναπηρίες. Από την ανασκόπηση της βιβλιογραφίας διαπιστώθηκε ότι η άσκηση στα άτομα με αναπηρία συμβάλλει στην μείωση του άγχους, του στρες και της κατάθλιψης, στην αύξηση της αυτοπεποίθησης και της αυτοεκτίμησης αλλά και γενικότερα στην καλύτερη ποιότητα ζωής. Τέλος, εντοπίζονται τα κενά που υπάρχουν στη βιβλιογραφία για μελλοντικές έρευνες ώστε να υπάρχει μια ολοκληρωμένη εικόνα για το πως επιδρά η άσκηση σε άτομα με αναπηρία αλλά και ποιο είδος άσκησης, ποια συχνότητα και ποια ένταση έχει τα καλύτερα αποτελέσματα.
description: The dissertation presents the psychological benefits of people with disability from their participation in sports activities. To make it more understandable to the reader, it analyzes the categories and types of disability. In addition, it describes the anatomy of the Central Nervous System whose damage can lead to motor, sensory, mental and intellectual disability. Also, through the literature, it presents types of exercise that are suitable for people with disabilities. In addition, it describes the benefits of exercise for people with disabilities, with particular emphasis on the psychological benefits. It also mentions the problems faced by the people with disability in their physical exercise. Finally, it identifies gaps in the literature for future research so that there is a complete picture of how exercise affects people with disability but also what type of exercise, what frequency and intensity has the best results.

description: Ο τουρισμός περιπέτειας σε ορεινές περιοχές γίνεται όλο ένα και περισσότερο πιο γνωστός καθώς οι τουρίστες περιπέτειας ψάχνουν για περισσότερες και πιο ιδιαίτερες εμπειρίες περιπέτειας. Στην Κεντρική Μακεδονία ο τουρίστες περιπέτειας πληθαίνουν με το πέρασμα του καιρού αναζητώντας νέες εμπειρίες και εμπειρίες που θα τους μείνουν αξέχαστες. Η Κεντρική Μακεδονία έχει μεγάλους ορεινούς όγκους οι οποίοι χαρίζουν στους τουρίστες περιπέτειας την άνεση της επιλογής και την δυνατότητα της ανάπτυξης νέων δεξιοτήτων. Είναι όμως σημαντικό οι φορείς τουρισμού της Κεντρικής Μακεδονίας να κατανοήσουν καλύτερα το πώς οι τουρίστες αντιλαμβάνονται την περιπέτεια την οποία επιλέγουν και αγοράζουν, τι τους οδηγεί να εμπλακούν με αυτές τις περιπέτειες και ποιες προσδοκίες έχουν από τους διάφορους φορείς. Είναι σημαντικό, επίσης, να κατανοήσουν πώς βλέπουν και αντιμετωπίζουν την τοπική κοινότητα και τους ντόπιους κατοίκους. Αυτά τα ερωτήματα οδήγησαν στο να δημιουργηθεί αυτή η έρευνα ώστε να ανακαλυφθούν τα συναισθήματα των τουριστών, όπως και το θυμικό τους να ανακαλύψουν νέους τόπους και να συναναστραφούν και να εμπλακούν με τους ντόπιους κατοίκους, ώστε να βοηθηθούν οι τουριστικοί φορείς και να αναπτύξουν τις τακτικές τους.
description: Mountain adventure tourism is becoming more and more popular as adventure tourists look for more and more unique adventure experiences. In Central Macedonia, the number of adventure tourists is increasing over time, looking for new and unforgettable experiences. Central Macedonia has large mountain ranges which give adventure tourists the comfort of choice and the possibility of developing new skills. However, it is important for tourism operators in Central Macedonia to better understand how tourists perceive the adventure they choose and buy, what drives them to get involved with these adventures and what expectations they have from the various operators. It is also important that they understand how they see and treat the local community and residents. These questions led to the creation of this research to discover the emotions of tourists as well as their motivation to discover new places and socialize and engage with residents in order to help tourism operators and develop their tactics.

The theory is valid for any periodicity of driving Hamiltonians that commute with themselves at all times and do not induce coherence in the WF. Continuous and stroke cycles arise in opposite limits of this theory, which encompasses hitherto unfamiliar cycle forms, dubbed here hybrid cycles. The theory allows us to discover the speed, power and efficiency limits attainable by incoherently-operating multilevel HE depending on the cycle form and the dynamical regimes.

description: The LOFAR Two-Metre Sky Survey (LoTSS) is an invaluable new tool for investigating the properties of sources at low frequencies and has helped to open up the study of galaxy populations in this regime. In this work, we perform a search for host galaxies of gamma-ray bursts (GRBs). We use the relative density of sources in Data Release 2 of LoTSS to define the probability of a chance alignment, $P_{\rm chance}$, and find 18 sources corresponding to 17 GRBs which meet a $P_{\rm chance}$<1% criterion. We examine the nature and properties of these radio sources using both LOFAR data and broadband information, including their radio spectral index, star formation rate estimates and any contributions from active galactic nucleus emission. Assuming the radio emission is dominated by star formation, we find that our sources show high star formation rates ($10^1$-$10^3$ $M_{\odot}$ yr$^{-1}$) compared with both a field galaxy sample and a sample of core-collapse supernova hosts, and the majority of putative hosts are consistent with ultraluminous infrared galaxy (ULIRG) classifications. As a result of our analyses, we define a final sample of eight likely GRB host candidates in the LoTSS DR2 survey.

description: The gravitational wave (GW) signals from the Galactic population of cataclysmic variables (CVs) have yet to be carefully assessed. Here we estimate these signals and evaluate their significance for LISA. First, we find that at least three known systems are expected to produce strong enough signals to be individually resolved within the first four years of LISA's operation. Second, CVs will contribute significantly to the LISA Galactic binary background, limiting the mission's sensitivity in the relevant frequency band. Third, we predict a spike in the unresolved GW background at a frequency corresponding to the CV minimum orbital period. This excess noise may impact the detection of other systems near this characteristic frequency. Fourth, we note that the excess noise spike amplitude and location associated with $P_{\rm{min}}\sim80~\mathrm{min}$ can be used to measure the CV space density and period bounce location with complementary and simple GW biases compared to the biases and selection effects plaguing samples selected from electromagnetic signals. Our results highlight the need to explicitly include the Galactic CV population in the LISA mission planning, both as individual GW sources and generators of background noise, as well as the exciting prospect of characterising the CV population through their GW emission.

description: Vacuum perturbations of the Kerr metric can be reconstructed from the corresponding perturbation in either of the two Weyl scalars $ψ_0$ or $ψ_4$, using a procedure described by Chrzanowski and others in the 1970s. More recent work, motivated within the context of self-force physics, extends the procedure to metric perturbations sourced by a particle in a bound geodesic orbit. However, the existing procedure leaves undetermined a certain stationary, axially-symmetric piece of the metric perturbation. In the vacuum region away from the particle, this "completion" piece corresponds simply to mass and angular-momentum perturbations of the Kerr background, with amplitudes that are, however, a priori unknown. Here we present and implement a rigorous method for finding the completion piece. The key idea is to impose continuity, off the particle, of certain gauge-invariant fields constructed from the full (completed) perturbation, in order to determine the unknown amplitude parameters of the completion piece. We implement this method in full for bound (eccentric) geodesic orbits in the equatorial plane of the Kerr black hole. Our results provide a rigorous underpinning of recent results by Friedman {\it et al.}\ for circular orbits, and extend them to non-circular orbits.

description: Background: African American (AA) women have higher incidence of aggressive, young-onset (<40 years) breast cancers. Young- and older-onset disease may have distinct tumor biologies and etiologies; however, studies investigating age differences among AA women have been rare and generally underpowered. Methods: We examined tumor characteristics and breast cancer risk factors associated with premenopausal young (<40) vs. older (40) AA women's breast cancer in the African American Breast Cancer Epidemiology and Risk Consortium (2,008 cases and 5,144 controls). Unconditional logistic regression models assessed heterogeneity of tumor biology and risk factor associations by age, overall, and by estrogen receptor status. Results: Premenopausal AA women <40 years had higher frequency of poorer-prognosis tumor characteristics compared with older women, including negative estrogen and progesterone receptor status, triple-negative subtype, higher grade, higher stage, and larger tumors. Adiposity (i.e., waist-to-hip ratio) and family history of breast cancer were more strongly associated with young-onset disease [case–control OR ¼ 1.46, 95% confidence interval (CI) ¼ 1.04–2.05; OR ¼ 3.10, 95% CI ¼ 2.08–4.63, respectively] compared with older-onset disease (OR ¼ 1.11, 95% CI ¼ 0.91–1.35; OR ¼ 1.57, 95% CI ¼ 1.26–1.94). Breastfeeding showed a slight inverse risk association among young women (OR ¼ 0.70, 95% CI ¼ 0.43–1.16). Oral contraceptive use was associated with increased risk regardless of age. Considering various cutoff points for young age (<40, <45, <50), age-related heterogeneity was greatest when <40 was used. Conclusions: Among premenopausal AA women, diagnosis before age 40 is associated with more aggressive breast tumor biology and some etiologic differences. Impact: Modifiable risk factors including breastfeeding, adiposity, and oral contraceptive use may be important targets for mitigating harms of young-onset breast cancer.

Towards a national diamond open access strategy for tertiary vocational education in Aotearoa New Zealand
Creators: name: Savage, James L
Publisher: name: Zenodo
Year: 2023

description: The Reform of Vocational Education (RoVE) in Aotearoa New Zealand is currently unifying all sixteen Institutes of Technology and Polytechnics and nine Industry Training Organisations into a single national entity. This newly formed ‘Te Pūkenga — New Zealand Institute of Skills and Technology’ is now the largest tertiary education organisation in the country, with a unique opportunity to establish open access principles at the foundation of its national network. This is facilitated by the alignment of the open access movement with the overarching values of Te Pūkenga: to be diverse, inclusive, and welcoming (manawa nui), to embrace progress and collaboration (manawa roa), and to be empowering and transparent (manawa ora). Newly formed in 2023, the role of Te Pūkenga Publishing Group will be to facilitate existing publishing activity while sharing and overseeing good practice across the network. Currently, three of the formerly independent organisations have a press that regularly publishes books, monographs, conference proceedings, and other works, and five currently publish a total of fourteen peer-reviewed journals. To minimise barriers for both creators and users of research, and give effect to the values of Te Pūkenga, we consider diamond open access the ideal: no publication or subscription fees, peer review, and retention of copyright by authors. Diamond open access ensures that our indigenous, professional, business and not-for-profit communities can benefit from the research that we publish, and removes barriers to publishing for authors without funding. This presentation will explore our progress towards defining and implementing this strategy.
Κοινωνιολογική προσέγγιση της διερμηνείας: Μια μελέτη περίπτωσης της διερμηνείας συνεδρίων στα ευρωπαϊκά όργανα

description: Ο σκοπός της παρούσας διπλωματικής είναι η προσέγγιση του επαγγέλματος του διερμηνέα από μια κοινωνιολογική σκοπιά, βασισμένη στη θεωρία του πεδίου του Pierre Bourdieu, μέσα από ημιδομημένες συνεντεύξεις επαγγελματιών διερμηνέων. Οι συνεντεύξεις χωρίζονται σε τρεις άξονες: την προσωπική σχέση του διερμηνέα με το επάγγελμα, το επάγγελμα καθαυτό και τέλος την αλληλεπίδραση με άλλα δρώντα υποκείμενα στο πεδίο της διερμηνείας. Αμφότεροι οι συνεντευξιαζόμενοι εργάζονται ως εξωτερικοί διερμηνείς για τα όργανα της Ευρωπαϊκής Ένωσης και διδάσκουν στο ΔΠΜΣ Διερμηνείας. Μέσα από τη μακροχρόνια πορεία τους στον κλάδο μιλούν για το πώς η διερμηνεία έχει αλλάξει όλα αυτά τα χρόνια, πώς προσαρμόστηκε στις νέες συνθήκες της πανδημίας και πώς κρίνουν οι ίδιοι ότι θα εξελιχθεί στο μέλλον. Από τις διηγήσεις τους βλέπουμε πόσο απαιτητικό είναι το επάγγελμα αυτό που από το ευρύ κοινό θεωρείται μια αυτοματοποιημένη διαδικασία.
description: The purpose of this thesis is to approach the profession of the interpreter from a sociological point of view, based on Pierre Bourdieu’s field theory, through semi-structured interviews of professional interpreters. The interviews are divided into three main parts: the interpreter's relationship with the profession, the profession as such, and the interaction with other agents in the field of interpretation. Both interviewees work as freelance interpreters for the institutions of the European Union and teach at the course of Conference Interpreting. Throughout their long career, they talk about how interpreting has changed over the years, how it has adapted to the new conditions of the pandemic and how they think it will evolve in the future. From their stories we see how demanding the profession is but nevertheless considered an automated process by the general public.

description: Using the representation theory of Yangians we construct the rational R-matrix which takes values in the adjoint representation of SU(n). From this we derive an integrable SU(n) spin chain with lattice spins transforming under the adjoint representation. However, the resulting Hamiltonian is found to be non-Hermitian.

description: Blumea megacephala essential oil, obtained through steam distillation of samples collected from the Shiwang Mountains in Guangxi Province, China, was analyzed using GC-FID and GC-MS. Among the 65 compounds identified in the oil, the main compounds were borneol (13.6 %), β-caryophyllene (9.56 %), germacrene D (9.09 %), sabinene (6.37 %), and α-humulene (4.78 %). Antimicrobial activity revealed that the essential oil (1000 μg/disc) has promising antimicrobial effects against several pathogens, giving satisfactory inhibition zone diameter values (21.5, 21.6, 23.4, 23.8, 21.9) and MIC values (125, 125, 62.5, 125, 125 μg/ml) against Gram-negative bacteria (Pseudomonas aeruginosa, Escherichia coli), Gram-positive bacteria (Bacillus subtilis, Staphylococcus aureus), and yeast (Hansenula anomala). Antioxidant and antimicrobial activities were correlated with chemical composition.

Noise-dissipation relation for nonlinear electronic circuits

Year: 2023
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: An extension of fluctuation-dissipation theorem is used to derive a "speed limit" theorem for nonlinear electronic devices. This speed limit provides a lower bound on the dissipation that is incurred when transferring a given amount of electric charge in a certain amount of time with a certain noise level (average variance of the current). This bound, which implies a high energy dissipation for fast, low-noise operations (such as switching a bit in a digital memory), brings together recent results of stochastic thermodynamics into a form that is usable for practical nonlinear electronic circuits, as we illustrate on a switching circuit made of an nMOS pass gate in a state-of-the-art industrial technology.
Η κριτική και ουτοπική διάσταση της Επιστημονικής Φαντασίας Η αναπαράσταση του ουτοπικού από τις ουτοπίες στην επιστημονική φαντασία

description: Η εργασία θα προσπαθήσει να εξερευνήσει τον τρόπο με τον αναπαριστάται η ουτοπία, συγκεκριμένα στο λογοτεχνικό είδος της Ουτοπίας και στην Επιστημονική Φαντασία. Στόχος είναι να αναδειχθούν οι κριτικές και ουτοπικές διαστάσεις της Επιστημονικής Φαντασίας και να διερευνηθεί το υπερβατολογικό ζήτημα της ίδιας της δυνατότητας αναπαράστασης της ουτοπίας. Εκκινώντας από τον ορισμό των δύο ειδών, της Επιστημονικής Φαντασίας ως το είδος της γνωσιακής ανοικείωσης και της ουτοπίας ως λεκτική κατασκευή που μιμείται το ιδρυτικό κείμενο του Thomas More, θα γίνει μία προσπάθεια χαρτογράφησης και ιστορικής αναδρομής των τρόπων με τους οποίους έχει εκφραστεί η ουτοπία στη λογοτεχνία για να αμφισβητηθεί εν τέλει ως προς την κριτική της διάσταση. Η ουτοπία έπειτα θα επαναοριστεί, αυτή τη φορά ως ουτοπική ερμηνευτική, αντλώντας από το έργο του Ernst Bloch, «Η Αρχή της Ελπίδας», και μέσα από την αντίστιξη αφηρημένης και συμπαγούς ουτοπίας θα επιχειρηθεί η ανάδειξη της Επιστημονικής Φαντασίας ως περισσότερο κριτικής και ουτοπικής από τις παραδοσιακές Ουτοπίες, ως το είδος εκείνο που είναι περισσότερο σε συμφωνία με την ουτοπία στην ερμηνευτική της θεώρηση.
description: The present paper will try to investigate the ways in which utopia is represented, specifically in the literary genre of utopia and science fiction. The purpose is to point out the critical and utopian aspects of science fiction and to investigate the transcendental problem of the very potential of utopian representation itself. Defining the two genres, of science fiction as the genre of cognitive estrangement, and utopia as the verbal construct that mimics the founding text of Thomas More, there will be an attempt of a historical mapping and retrospection of the ways in which utopia has been expressed in literature, only to bring its critical aspect into question. Utopia will then be redefined, this time as utopian hermeneutics, drawing from the work of Ernst Bloch, “The Principle of Hope”, and through the juxtaposition of abstract and concrete utopias, science fiction will emerge as the genre that is more critical and utopian than traditional utopian texts, as the genre that is more compatible with utopia in its hermeneutical dimension.

description: The present review is based on the lectures that the author had been giving during several years at the Swiss Federal Institute of Technology in Zurich (ETH Zurich). Being bounded by lecture frames, the selection of the material, by necessity, is limited and is motivated by the author's research interests. The paper gives an introduction to the physics of social systems, providing the main definitions and notions used in the modeling of these systems. The behavior of social systems is illustrated by several simple typical models. The present part considers equilibrium systems. Nonequilibrium systems will be presented in the second part of the lectures. The style of the paper combines the features of a tutorial and a survey, which, from one side, makes it easy to read for nonspecialists aiming at grasping the basics of social physics, and from the other side, describes several rather recent original models containing new ideas that could be of interest to experienced researchers in the field.

description: Last complete novel completed by Charles Dickens and is one of his most sophisticated works, combining savage satire with social analysis. In the opening chapters a body is found in the Thames and identified as that of John Harmon, a young man recently returned to London to receive his inheritance. Were he alive, his father's will would require him to marry Bella Wilfer, a beautiful, mercenary girl whom he had never met. Instead, the money passes to the working-class Boffins, and the effects spread into various corners of London society. Issued monthly from May 1864 to November 1865 in illustrated green paper covers. Chapters 8-11: Chapter 8. A few grains of pepper -- Chapter 9. Two places vacated -- Chapter 10. The doll's dressmaker discovers a word -- Chapter 11. Effect is given to the doll's dressmaker's discovery
