description: Quillen et al.(2007) presented an imaging survey with the {\it Spitzer Space Telescope} of 62 brightest cluster galaxies with optical line emission located in the cores of X-ray luminous clusters. They found that at least half of these sources have signs of excess infrared emission. Here we discuss the nature of the IR emission and its implications for cool core clusters. The strength of the mid-IR excess emission correlates with the luminosity of the optical emission lines. Excluding the four systems dominated by an AGN, the excess mid-infrared emission in the remaining brightest cluster galaxies is likely related to star formation. The mass of molecular gas (estimated from CO observations) is correlated with the IR luminosity as found for normal star forming galaxies. The gas depletion time scale is about 1 Gyr. The physical extent of the infrared excess is consistent with that of the optical emission line nebulae. This supports the hypothesis that the star formation occurs in molecular gas associated with the emission line nebulae and with evidence that the emission line nebulae are mainly powered by ongoing star formation. We find a correlation between mass deposition rates (${\dot M}_X$) estimated from the X-ray emission and the star formation rate estimated from the infrared luminosity. The star formation rates are 1/10 to 1/100 of the mass deposition rates suggesting that the re-heating of the ICM is generally very effective in reducing the amount of mass cooling from the hot phase but not eliminating it completely.

description: Combining two Bose-Einstein condensates (BECs) may result in a miscible or immiscible mixture, or even a violent implosion. We theoretically demonstrate that dipolar two-component BECs produce far richer physics than their nondipolar counterparts. Intriguingly, when both components have equivalent dipoles, the transition to immiscibility is largely unaffected by dipolar physics, yet the dipoles maximally affect stability. Conversely, antiparallel dipoles strongly affect miscibility but have little effect on stability. By performing three-dimensional calculations of the ground states and their excitations, we find strong dependencies on the confinement geometry. We explore and elucidate the various phononic and rotonic phase transitions, as well as symmetry preserving crossovers.

description: Consider a unit-resistive plate in the shape of a regular polygon with 2n sides, in which even-numbered sides are wired to electrodes and odd-numbered sides are insulated. The response matrix, or Dirichlet-to-Neumann map, allows one to compute the currents flowing through the electrodes when they are held at specified voltages. We show that the entries of the response matrix of the regular 2n-gon are given by the differences of cotangents of evenly spaced angles, and we describe some connections with the limiting distributions of certain random spanning forests.

Insubordinated puisque in French. Grammaticalization, De-Grammaticalization, Reanalysis?
Creators: name: Detges, Ulrich
Publisher: name: JournaLIPP
Year: 2017

description: In Modern French, main-clause initial puisque is a discourse-marker which coexists with a homonymous subordinating causal connective. Diachronically, it has emerged from the latter through a process of insubordination. It is often assumed that the diachronies of discourse makers can be meaningfully described as grammaticalization processes. This view has been challenged by Detges & Waltereit­ (2009, 2016) on the grounds that grammar in the narrow sense (e.g. inflectional mor­phology) on the one hand and discourse markers and modal particles on the other are the outcome of different kinds of diachronic processes. For sentence-initial puisque, this question is further complicated by the fact that insubordination has been claimed to be a counter-example to basic assumptions of established grammaticalization theo­ries. Against this backdrop, this article pursues two objectives. Firstly, an account will be given of the diachronic mechanisms that turned the subordinating connective puis­que into a main-clause-initial item. It will be shown that the emergence of main-clause-initial puisque is brought about by a pragmatically motivated reanalysis whereby a frequent usage-effect was conventionalized as the construction's new meaning. This change took place in elaborative discourse contexts (see D’Hertefelt / Verstraete 2014) where subordinating puisque was used to negotiate the next move in discourse building. Secondly (and more importantly), I will discuss the question of whether this process can be meaningfully classified as an instance of grammaticalization.

description: We calculate the critical magnetic fields for vortex expulsion for an infinitely long superconducting strip, using the Ginzburg-Landau formalism. Two critical fields can be defined associated with the disappearance of either the energetic stability or metastability of vortices in the center of the strip for decreasing magnetic fields. We compare the theoretical predictions for the critical fields in the London formalism with ours and with recently published experimental results. As expected, for narrow strips our results reproduce better the experimental findings.

Πιο συγκεκριμένα, γίνεται αναφορά στους λόγους για τους οποίους προέκυψε η ανάγκη για την δημιουργία ενιαίας αγοράς ενέργειας, οι πέντε πυλώνες της ευρωπαϊκής πολιτικής και οι στόχοι αυτής. Επιπλέον, όσο αφορά τα χρηματιστήριο ενέργειας, γίνεται αναφορά στα γενικά χαρακτηριστικά αυτού, στον τρόπο λειτουργίας του αλλά κυρίως στα ακραία φαινόμενα που παρατηρούνται στις τιμές της ηλεκτρικής ενέργειας, τα οποία οδηγούν στην εμφάνιση των ακραίων θετικών τιμών. Στο δεύτερο μέρος, το εμπειρικό, έγινε μια προσπάθεια περιγραφής της συμπεριφοράς των τιμών υπό την επίδραση των ακραίων θετικών τιμών που παρουσιάζονται στις τιμές της ηλεκτρικής ενέργειας. Συγκεκριμένα, έγινε ανάλυση των τιμών δύο χωρών κατά την διάρκεια της δεκαετίας 2009-2018 σε ημερήσιες και ωριαίες τιμές, μέσω διάφορων στατιστικών, έγιναν διάφοροι έλεγχοι όπως είναι τα τεστ κανονικότητας και αυτοσυσχέτισης, παρουσιάστηκαν κάποια χαρακτηριστικά των χρονοσειρών αυτών, όπως είναι η εποχικότητα, το mean-reversion, και χρησιμοποιήθηκε το μοντέλο των Lucia και Schwarz, στο οποίο ενσωματώθηκε ο παράγοντας των ακραίων τιμών, ο οποίος εφαρμόστηκε ξεχωριστά για κάθε χώρα και εντοπίστηκαν οι ακραίες αυτές τιμές, για να αποδειχθεί τελικά η επίδραση αυτών στις τιμές της ηλεκτρικής ενέργειας
description: This Dissertation consists of two main parts, the theoretical and the empirical. The first part, the theoretical one, includes some general information about EU energy union and the energy exchange. To be more detailed, there is an analysis about the reasons that EU were driven to the energy union, the five dimensions of it and the targets of this policy. Furthermore, a theoretical analysis about energy exchange, the factors which affect the spot prices, the operation mode of the exchange and some abnormally extreme prices which can be observed and affect the spot prices. At the second part, the empirical one, I address the issue of modelling spot electricity prices. Moreover, is given an extensive research about the statistical features of electricity prices such as the seasonality, the mean-reversion and the existence of jumps and spikes by using daily and hourly spot prices from two different European energy exchanges, from Germany and from France, at the period from 2009 to 2018. An effort has been made to include the parameter of jumps in the model of Lucia and Schwarz, which has been identified through an algorithm separate for the prices from each country, and prove the positive influence at the spot prices of energy markets
On causality and superluminal behavior in classical field theories. Applications to k-essence theories and MOND-like theories of gravity

description: Field theories whose full action is Lorentz invariant (or diffeomorphism invariant) can exhibit superluminal behaviors through the breaking of local Lorentz invariance. Quantum induced superluminal velocities are well-known examples of this effect. The issue of the causal behavior of such propagations is somewhat controversial in the literature and we intend to clarify it. We provide a careful analysis of the meaning of causality in classical relativistic field theories, and we stress the role played by the Cauchy problem and the notions of chronology and time arrow. We show that superluminal behavior threaten causality only if a prior chronology on spacetime is chosen. In the case where superluminal propagations occur, however, there is at least two non conformally related metrics on spacetime and thus two available notions of chronology. These two chronologies are on equal footing and it would thus be misleading to choose \textit{ab initio} one of them to define causality. Rather, we provide a formulation of causality in which no prior chronology is assumed. We argue this is the only way to deal with the issue of causality in the case where some degrees of freedom propagate faster than others. We actually show that superluminal propagations do not threaten causality. As an illustration of these conceptual issues, we consider two field theories, namely k-essences scalar fields and bimetric theories of gravity, and we derive the conditions imposed by causality. We discuss various applications such as the dark energy problem, MOND-like theories of gravity and varying speed of light theories.

Prozesse up and down the cline und die Frage der (De-)Grammatikalisierung

Publisher: name: JournaLIPP
Year: 2017

description: Grammatikalisierung ist nach Fischer, Norde und Perridon (2004) ein down the cline gerichteter Prozess. Präzisierend fassen ihn Lehmann (2004) und Harnisch (2004) als Abstieg auf der Skala der Konstruktionsebenen: Phrase – Wort – Klitikon – Affix. Umgekehrt wird De-Grammatikalisierung als up the cline gerichteter Prozess und als Aufstieg auf der Skala der Konstruktionsebenen aufgefasst: Affix – Klitikon – Wort – Phrase. Bei beiden Prozessarten wird der Bereich bedeutungstragender Einheiten (die Sphäre der Morphie) nicht verlassen. Harnisch (2004) bezieht darüber hinaus jedoch die Konstruktionsebene der reinen (bedeutungslosen) Lautsubstanz (die Sphäre der Amorphie) mit ein und betrachtet auch Prozesse, die – down oder up the cline – die Grenze zwischen Morphie und Amorphie überschreiten. Doch anders, als noch bei Harnisch (2004) konzipiert, hat man es bei Prozessen, die down the cline die Grenze zwischen Morphie und Amorphie übertreten, nicht mehr mit Grammatikalisierung zu tun, denn bei diesem Übertritt geht ja Grammatizität, verstanden als explizite Kennzeichnung grammatischer Kategorien, gerade verloren. Umgekehrt hat man es bei Prozessen, die up the cline die Grenze zwischen Amorphie und Morphie übertreten, nicht mehr mit De-Grammatikalisierung zu tun, denn bei diesem Übertritt wird ja gerade Grammatizität, wiederum verstanden als explizite Kennzeichnung grammatischer Kategorien, gewonnen. Die sich hierbei abspielenden Prozesse werden anhand von Beispielen aus den Bereichen Sprachwandel, Fremdwortintegration und Spracherwerb veranschaulicht. Ein Exkurs soll verdeutlichen, dass sich solche Erscheinungen nicht nur in der Flexionsmorphologie abspielen (als De-/Grammatikalisierung) sondern auch in der Wortbildungsmorphologie (als Ent-/Derivationalisierung). Abschließend wird eine Typologie sowohl der Vorgänge vorgeschlagen, die sich innerhalb der Sphäre der Morphie abspielen, als auch der Vorgänge, bei denen die Grenze zwischen Morphie oder Amorphie in der einen oder andern Richtung überschritten wird.

description: Models at various levels of resolution are commonly used, both for forest management and in ecological research. They all have comparative advantages and disadvantages, making desirable a better understanding of the relationships between the various approaches. It is found that accounting for crown and root plasticity creates more realistic links between spatial and non-spatial models than simply ignoring spatial structure. The article reviews also the connection between distance-independent models and size distributions, and how distributions evolve over time and relate to whole-stand descriptions. In addition, some ways in which stand-level knowledge feeds back into detailed individual-tree formulations are demonstrated. The presentation intends to be accessible to non-specialists. Study implications: Introducing plasticity improves the representation of physio-ecological processes in spatial modelling. Plasticity explains in part the practical success of distance-independent models. The nature of size distributions and their relationship to individual-tree and whole-stand models are discussed. I point out limitations of various approaches and questions for future research.

description: Questo articolo cerca di offrire alcune strategie per presentare il tema dell’antimafia all’interno dei corsi di scuola secondaria di italiano come lingua straniera. Si mette in evidenza come i movimenti antimafia rappresentino una realtà importante e positiva della società italiana contemporanea e come, per questo motivo, possano essere inclusi nell’insegnamento della cultura italiana nei curricoli linguistici. Negli ultimi anni alcune associazioni hanno iniziato a combattere la mafia, grazie alla partecipazione dei cittadini, un punto di vista che solleva l’interesse degli studenti stranieri. Le lezioni qui descritte hanno avuto luogo in Austria e si concentrano sul concetto di “Consumo critico” sviluppato da Addiopizzo (Palermo, Italia), associazione che ha contribuito alle attività svolte nel corso delle lezioni rispondendo a una lista di domande formulate da parte degli studenti coinvolti. Da un punto di vista metodologico, principi e tecniche del CLIL (Content and Language Integrated Learning) hanno contribuito a pianificare le lezioni, al fine di coniugare lingua e contenuti in modo produttivo. L’articolo comprende una descrizione step-to-step delle attività svolte.

Are you Afraid of the mafia? Antimafia Culture through CLIL in Teaching Italian as a Foreign Language

Gioia Panzarella

This article seeks to offer some strategies for presenting the topic of antimafia within secondary school courses of Italian as a foreign language. I argue that antimafia movements represent an important and positive reality of contemporary Italian society and, for this reason, they can be included in the teaching of Italian culture within language curricula. In recent years some associations have started to fight the mafia thanks to citizens’ participation, a point of view which raises students’ interest. The lessons here described took place in Austria and focus on the notion of “consumo critico” developed by Addiopizzo (Palermo, Italy), an association that contributed to the activities by answering a list of questions posed by the students involved. From a methodological point of view, CLIL (Content and Language Integrated Learning) principles and techniques were used to plan the lessons, in order to combine language and content in a productive way. The article includes a step-to-step description of the activities.

description: We computed the self-organisation process of a monodisperse collection of spherical micrometric particles trapped in a two-dimensional (2D) thin liquid film isothermally dried on a chemically inert substrate. The substrate is either flat or indented to create linear stripes on its surface. The numerical results are illustrated and discussed in the light of experimental ones obtained from the drying of diamond particles water based suspension ($d_{50} = 10 μm$) on a glass substrate. The drying of the suspension on a flat substrate leads to the formation of linear patterns and small clusters of micrometric particles distributed over the whole surface of the substrate, whereas the drying of the suspension on a indented substrate leads to the aggregation of the particles along one side of the stripe which has a higher roughness than the other side of the stripe. This is an easy experimental way to obtain colloidal selforganized patterns.

description: Questa ricerca si pone l’obiettivo di identificare strategie efficaci nella gestione dell’insegnamento uno a uno in contesti professionali. A partire da un’attenta riflessione sulle peculiarità di questo ambito di insegnamento, si analizzano i possibili percorsi di apprendimento che l’insegnante può intraprendere al fine di impostare una azione didattica incisiva. Si esaminano in particolare lo sviluppo della competenza strategica e metacognitiva e la costruzione della personalità interculturale come possibili chiavi di accesso a un apprendimento più consapevole e autonomo. Attraverso lo studio di tre casi differenti, questo contributo intende fornire idonei strumenti di analisi che possano guidare l’insegnante nel riconoscimento di un profilo non solo linguistico, ma anche cognitivo, metacognitivo e socio-affettivo dell’apprendente e nell’impostazione di una diversa azione didattica in armonia con le caratteristiche dell’allievo.

Marcella Panascì

This study aims at identifying effective strategies in one-to-one teaching in professional contexts. Starting from a careful consideration of the peculiarities of this type of teaching, this study analyses the possible learning paths which the teacher can take in order to plan successful didactic actions. The development of strategic and meta-cognitive competences and the construction of an intercultural personality will be examined as possible way to a more independent and conscious way of learning. Through three different case studies, this article offers analysis strategies so that the teacher can recognize a student’s profile not only linguistically, but also which including cognitive, meta-cognitive and affective aspects in order to plan ad hoc didactic actions in harmony with the learner’s characteristics.

Ne evidenzia gli aspetti glottodidattici, sociolinguistici e socioculturali, per illustrare come l’apprendimento/acquisizione della lingua seconda, in reclusione, sia facilitato da una didattica integrata e flessibile, dove l’arte e la L2 sono funzionali al processo di rieducazione del detenuto.

Educational projects for foreign prisoners

Claudia Savino

This paper offers ideas for teaching sociolinguistic literacy to foreign prisoners, through the integrated testing of some language teaching methodologies. In particular, it proposes an interdisciplinary laboratory where Italian L2 activities are mixed with figurative art. In the first part, the article outlines the communicative interactions within the prison facilities, with the cultural implications that derive from it. Mention is made of the pilot projects of the University for Foreigners in Siena in this area. In the second part, the author describes an educational project under development, aimed at Italian and foreign prisoners: language education through art for teaching intercultural communication. It highlights language teaching, sociolinguistic and socio-cultural aspects, to illustrate how the learning/acquisition of a second language, in prison, is facilitated by integrated and flexible learning, where the art and L2 are functional in the process of the rehabilitation of prisoners.

description: Quantum mechanical systems whose symmetry is given by $\mathbb{Z}_2^3$-graded version of superconformal algebra are introduced. This is done by finding a realization of a $\mathbb{Z}_2^3$-graded Lie superalgebra in terms of a standard Lie superalgebra and the Clifford algebra. The realization allows us to map many models of superconformal quantum mechanics (SCQM) to their $\mathbb{Z}_2^3$-graded extensions. It is observed that for the simplest SCQM with $\mathfrak{osp}(1|2)$ symmetry there exist two inequivalent $\mathbb{Z}_2^3$-graded extensions. Applying the standard prescription of conformal quantum mechanics, spectrum of the SCQMs with the $\mathbb{Z}_2^3$-graded $\mathfrak{osp}(1|2)$ symmetry is analyzed. It is shown that many models of SCQM can be extended to $\mathbb{Z}_2^n$-graded setting.
Application of optimization for the enzymatic synthesis of sweet aspartyl dipeptide analogs catalyzed by thermolysin
Creators: name: Lee, Grace Ilah
Publisher: name: University of British Columbia
Year: 2008

description: The enzymatic peptide synthesis of two sweet dipeptide analogs (aspartyl derivatives), Z-L-Asp-Tyr-OMe and Z-L-Asp-Met-OMe, was attempted using thermolysin as a catalyst. These two dipeptides are analogs of Z-L-Asp-Phe-OMe, the precursor to aspartame, which has already been successfully synthesized enzymatically using thermolysin. Random Centroid Optimization was employed to obtain optimal conditions for maximum yield. Seven factors were optimized for each peptide and they included: reactant concentration (only the amino component for Z-L-Asp-Tyr-OMe but both carboxyl and amino components for Z-L-Asp-Met- OMe), solvent concentration, buffer concentration, enzyme concentration, calcium chloride concentration, pH and temperature. Factor ranges were entered into the Random Centroid Optimization program, which generated the conditions for the experiments. Organic solvents were used in order to shift the equilibrium towards synthesis. A mixture of two solvents, water-miscible dimethylformamide (DMF), and water-immiscible ethyl acetate (EA), were used for both the first and second cycles in the optimization of Z-L-Asp-Tyr-OMe. For Z-LAsp- Met-OMe, glycerol, a polyol, was used in the first cycle but in the second cycle, another polyol, ethanediol was substituted because glycerol appeared to have an inhibitory effect on the enzyme. The maximum yield of Z-L-Asp-Tyr-OMe was 2.13 ± 0.46% (Mean ± S.D., n=3) under the following conditions: 80mM Z-L-Asp, 154mM Tyr-OMe, 2.3/9.7/88 DMF/EA/buffer, 39μM thermolysin, 7mM CaCl2, pH 6.3, at 46°C for 24 hours. The optimum yield of Z-L-Asp-Met-OMe was 9.13 ± 1.22% (Mean ± S.D., n=3) under the following conditions: 53mM Z-L-Asp, 96mM Met-OMe, 2/98 ethanediol/buffer, 35μM thermolysin, 3.8mM CaCl2, pH 5.1, at 49°C for 24 hours. Random Centroid Optimization was shown to be a useful method for attaining the conditions of maximum peptide synthesis, especially with the Z-L-Asp-Met-OMe. However, there were few clear indications of which factors most affected the yield. In general, it was found that the type of solvent used definitely had a great impact on the synthesis of both peptides. Z-L-Asp-Tyr-OMe synthesis was not very successful since the DMF:EA solvents did not sufficiently solubilize the reactants. In addition, high concentrations of solvents which are normally used in other systems could not be used for this synthesis. This indicates that the effect of the solvent on the enzyme must be examined further. It was apparent that not only the solvent had an effect on the synthesis, but that other factors were also important, although the nature of these other factors could not be deduced from this study.

In secondo luogo, si è scelto di approfondire le caratteristiche dell’apporto para-testuale, fornendo un’analisi completa della didascalia e alcune notizie di tipo storico. In terzo luogo si sono esaminati casi particolari di didascalie; nello specifico, sono state scelte quelle che accompagnano i dipinti presenti nelle prime cinque sale del Museo del 900 a Milano e sono stati forniti degli esempi concreti a supporto dell’analisi linguistica.

Linguistic characteristics of captions in art, a study case: the: Milan’s Museo del 900 (Museum of the Twentieth Century)

Elena Villa

The aim of this work was to emphasize the importance of paratextual apparatus with which artworks are presented; in particular, the author analyzed the linguistic structure and the specific characteristics of captions. First of all, in order to briefly analyze the language of art history, linguistic research was conducted. It built on what are considered to be the three main levels of analysis when jargons is concerned: lexicon, morphosyntax and textuality. Secondly, the author chose to examine in depth the characteristics of the paratextual contribution, by making a complete analysis of captions and giving historical information. Thirdly, the author provided concrete examples of captions to support his previous linguistic observation choosing those associated with the paintings of the first five rooms of Milan’s Museo del 900.

description: In recent years, Vietnam witnesses the mass development of social network users on different social platforms such as Facebook, Youtube, Instagram, and Tiktok. On social medias, hate speech has become a critical problem for social network users. To solve this problem, we introduce the ViHSD - a human-annotated dataset for automatically detecting hate speech on the social network. This dataset contains over 30,000 comments, each comment in the dataset has one of three labels: CLEAN, OFFENSIVE, or HATE. Besides, we introduce the data creation process for annotating and evaluating the quality of the dataset. Finally, we evaluated the dataset by deep learning models and transformer models.

Analysis of spin precession in binary black hole systems including quadrupole-monopole interaction

description: We analyze in detail the spin precession equations in binary black hole systems, when the tidal torque on a Kerr black hole due to quadrupole-monopole coupling is taken into account. We show that completing the precession equations with this term reveals the existence of a conserved quantity at 2PN order when averaging over orbital motion. This quantity allows one to solve the (orbit-averaged) precession equations exactly in the case of equal masses and arbitrary spins, neglecting radiation reaction. For unequal masses, an exact solution does not exist in closed form, but we are still able to derive accurate approximate analytic solutions. We also show how to incorporate radiation reaction effects into our analytic solutions adiabatically, and compare the results to solutions obtained numerically. For various configurations of the binary, the relative difference in the accumulated orbital phase computed using our analytic solutions versus a full numerical solution vary from about 0.3% to 1.8% over the 80 - 140 orbital cycles accumulated while sweeping over the orbital frequency range 20 - 300 Hz. This typically corresponds to a discrepancy of order 5-6 radians. While this may not be accurate enough for implementation in LIGO template banks, we still believe that our new solutions are potentially quite useful for comparing numerical relativity simulations of spinning binary black hole systems with post-Newtonian theory. They can also be used to gain more understanding of precession effects, with potential application to the gravitational recoil problem, and to provide semi-analytical templates for spinning, precessing binaries.

description: Transmission spectroscopy is the widely used observational technique that exploits the planetary transit events with aim to characterize the exoplanetary atmospheres. While it already revealed atomic and molecular absorption, haze layers and thick clouds in about two dozen of objects, the literature presents some worthy mentioned discrepant results on individual targets. An example of controversial results in the literature is the case of HAT-P-12b, which I solved successfully during my studies. Intriguingly, two independent investigations from different groups, one with ground-based observations and one using the Hubble Space Telescope (HST), concluded to contradicting transmission spectra, interpreted from opaque clouds in the atmosphere to a Rayleigh scattering slope. The optical slope in this case is affected by the orbital parameters yielding to inconsistencies. I will present this degeneracy investigated for the entire parameter space with aim to ameliorate the quality of the scientific output.
Grammaticalization and automation
Creators: name: Lehmann, Christian

description: Every human activity including language is part of a teleonomic hierarchy, where subordinate processes serve superordinate goals. The goals are pursued consciously; the processes run automatically. A teleonomic hierarchy is, at the same time, a scale between the poles of control and automation. Automation is the downgrading of an action to the level of an uncontrolled process. Regain of control over a process that has been automatized is hard or impossible. Language activity, too, is controlled or automatic in different aspects and to different degrees. The speaker’s freedom is realized at two logical levels: • At the lower level, his use of grammatical operations and formatives is not free, but determined by rules of the linguistic system. • At the higher level, he can choose the components of his activity which he wants to control, leaving the rest to automatisms of the system. Grammaticalization subjects operations and items to constraints of the system. This creates a uniform relation between conditioning factor and construction formed. This relation, together with frequency of use, is responsible for the automation of grammar. Since processes once automated are withdrawn from control, degrammaticalization is all but impossible.

description: DNA loop formation is one of several mechanisms used by organisms to regulate genes. The free energy of forming a loop is an important factor in determining whether the associated gene is switched on or off. In this paper we use an elastic rod model of DNA to determine the free energy of forming short (50--100 basepair), protein mediated DNA loops. Superhelical stress in the DNA of living cells is a critical factor determining the energetics of loop formation, and we explicitly account for it in our calculations. The repressor protein itself is regarded as a rigid coupler; its geometry enters the problem through the boundary conditions it applies on the DNA. We show that a theory with these ingredients is sufficient to explain certain features observed in modulation of in vivo gene activity as a function of the distance between operator sites for the lac repressor. We also use our theory to make quantitative predictions for the dependence of looping on superhelical stress, which may be testable both in vivo and in single-molecule experiments such as the tethered particle assay and the magnetic bead assay.

description: The classification of time-series data is pivotal for streaming data and comes with many challenges. Although the amount of publicly available datasets increases rapidly, deep neural models are only exploited in a few areas. Traditional methods are still used very often compared to deep neural models. These methods get preferred in safety-critical, financial, or medical fields because of their interpretable results. However, their performance and scale-ability are limited, and finding suitable explanations for time-series classification tasks is challenging due to the concepts hidden in the numerical time-series data. Visualizing complete time-series results in a cognitive overload concerning our perception and leads to confusion. Therefore, we believe that patch-wise processing of the data results in a more interpretable representation. We propose a novel hybrid approach that utilizes deep neural networks and traditional machine learning algorithms to introduce an interpretable and scale-able time-series classification approach. Our method first performs a fine-grained classification for the patches followed by sample level classification.

The Virgin Suicides

description: This dissertation explores the function of the female body in Jeffrey Eugenides’s The Virgin Suicides. As I demonstrate, the female body serves as the locus where the novel’s two major constitutive axes converge. The first axis is that of the text’s narrative organization. More precisely, the novel’s central plural narrative voice is interwoven with an abundance of different narrative voices. I locate the drive that produces the novel’s narrative thrust in the centrality of the female body. The second axis has to do with the novel’s generic self-identification. The narrative consciously uses the tropes of the Suburban Gothic, and in doing so, problematizes the female body within the American Suburb, and the Gothic genre. I argue that, while most narrative voices and gothic representations of femininity in the novel ostensibly reproduce the dominant patriarchal ideology, a number of narrative moments insidiously undermine this ideology, therefore enabling a reading of the novel as critical of patriarchy.
description: Στην παρούσα εργασία διερευνάται ο ρόλος του γυναικείου σώματος στις Αυτόχειρες Παρθένους του Τζέφρι Ευγενίδη. Όπως υποστηρίζω, το γυναικείο σώμα λειτουργεί ως σημείο τομής των δύο κύριων καταστατικών αξόνων του μυθιστορήματος. Ο πρώτος άξονας είναι αυτός της αφηγηματικής οργάνωσης του κειμένου. Πιο συγκεκριμένα, η κεντρική αφηγηματική φωνή του μυθιστορήματος διαπλέκεται με μια πληθώρα περιφερειακών αφηγηματικών φωνών. Είναι δε στην κεντρική θέση του γυναικείου σώματος μέσα στο βιβλίο που εντοπίζω την κινητήριο δύναμη που κατευθύνει την ανάπτυξη της αφήγησης. Ο δεύτερος άξονας αφορά τον ειδολογικό χαρακτήρα του κειμένου. Ειδικότερα, όπως θα δείξω, στο εν λόγω έργο γίνεται μεθοδική χρήση των εκφραστικών τρόπων του λεγόμενου Προαστιακού Γοτθικού Μυθιστορήματος, με συνέπεια την ανάδειξη μιας σειράς από προβληματικές που σχετίζονται με τη θέση του γυναικείου σώματος, τόσο εντός των Αμερικανικών προαστίων όσο και εντός του λογοτεχνικού είδους του Γοτθικού Mυθιστορήματος. Σύμφωνα με το κεντρικό μου επιχείρημα, ενώ η πλειονότητα των αφηγηματικών φωνών και των αναπαραστάσεων της θηλυκότητας μέσα στο μυθιστόρημα φαινομενικά αναπαράγουν την ιδεολογία της πατριαρχίας, την ίδια ώρα, μια σειρά από αφηγηματικές στιγμές υποσκάπτουν, έστω και έμμεσα, τη συγκεκριμένη ιδεολογία, επιτρέποντας την ανάγνωση του μυθιστορήματος ως κειμένου που στέκεται κριτικά απέναντι στον κυρίαρχο πατριαρχικό λόγο.

Demonstrative reinforcement cycles and grammaticalization
Creators: name: Vindenes, Urd
Publisher: name: JournaLIPP
Year: 2017

description: Demonstratives, broadly defined as deictic expressions, do not develop through grammaticalization (Diessel 1999: 150). The renewal of demonstratives, and the mechanisms and motivations underlying such processes, have not been studied in great detail. Greenberg’s (1978) observation that demonstratives are often replaced by reinforced forms might shed light on this diachronic process, and this study aims to explore this phenomenon further, as well as its connection with grammaticalization. I hypothesize that the frequent reinforcement of demonstratives can lead to the development of new demonstratives, which may catalyze the grammaticalization of old ones. The hypothesis presented here differs from many other accounts of renewal in that it sees reinforcement as a possible driving force behind grammaticalization, and not vice versa, as suggested in Diessel (2006: 474) and van Gelderen (2011: 210), among others.

description: Estimating stellar ages is important for advancing our understanding of stellar and exoplanet evolution and investigating the history of the Milky Way. However, ages for low-mass stars are hard to infer as they evolve slowly on the main sequence. In addition, empirical dating methods are difficult to calibrate for low-mass stars as they are faint. In this work, we calculate ages for Kepler F, G, and crucially K and M dwarfs, using their rotation and kinematic properties. We apply the simple assumption that the velocity dispersion of stars increases over time and adopt an age--velocity--dispersion relation (AVR) to estimate average stellar ages for groupings of coeval stars. We calculate the vertical velocity dispersion of stars in bins of absolute magnitude, temperature, rotation period, and Rossby number and then convert velocity dispersion to kinematic age via an AVR. Using this method, we estimate gyro-kinematic ages for 29,949 Kepler stars with measured rotation periods. We are able to estimate ages for clusters and asteroseismic stars with an RMS of 1.22 Gyr and 0.26 Gyr respectively.
