SCRITTURA BILINGUE: FENOMENI DI CONTATTO LINGUISTICO IN TESTI ARGOMENTATIVI E NARRATIVI DI RAGAZZI BILINGUI ITALO-TEDESCHI
Creators: name: Barberio, Teresa

description: Nell’immaginario collettivo Monaco di Baviera risulta essere la città più a nord dell’Italia (die nördlichste Stadt Italiens), aspetto sottolineato anche dalla forte presenza italiana che, al momento, si delinea come la più numerosa dopo quella turca e croata; in tale prospettiva bisogna considerare, inoltre, l’alto numero di ragazzi italiani bilingue in età scolare che vivono sul territorio. Malgrado la maggior parte degli studi linguistici con probandi bilingue italo-tedeschi sia basata su dati orali, recenti ricerche sul rendimento scolastico dei ragazzi italiani in Baviera e in Germania hanno rivelato, soprattutto nello scritto, basse competenze non solo nella lingua di origine, ma anche in tedesco. L’acquisizione di competenze testuali concerne, infatti, aspetti linguistici diversi rispetto al linguaggio spontaneo, dai quali spesso risultano fenomeni di contatto linguistico. Ciò avviene non solo a livello lessicale, ma anche morfosintattico e di organizzazione del testo. Attraverso l’analisi di testi argomentativi e narrativi in italiano e in tedesco di 53 ragazzi bilingue della nona e decima classe della Realschule, del Gymnasium e della Europäische Schule, il seguente studio si pone in primo luogo l’obiettivo di esaminare la tipologia dei fenomeni di contatto linguistico realizzati. Writing in two languages: phenomena of linguistic contact in argumentative and narrative texts by bilingual Italian-German children In the collective imagination, Munich seems to be the northernmost city in Italy (die nördlichste Stadt Italiens), an aspect underlined by a strong Italian presence, the most numerous after the Turkish and Croatian communities. In this perspective, it is also necessary to consider the high number of bilingual Italian school-age children living in this area. Despite the fact that most studies about bilingual Italian-German pupils are based on oral data, recent research on the school performance of Italian children in Bavaria and Germany has revealed poor writing skills, not only in the language of origin, but also in German. The acquisition of textual competence concerns different linguistic aspects with respect to spontaneous language, which often results in phenomena of linguistic contact. This occurs not only regarding lexis, but also morpho-syntax and text organization. Through the analysis of argumentative and narrative texts in Italian and German written by 53 bilingual ninth and tenth-grade students from three different types of schools (Realschule, Gymnasium and Europäische Schule), this study aims to examine the typology of the phenomena of linguistic contact that occur in these kinds of texts.

description: Tramite l’insegnamento delle e nelle lingue italiana e tedesca, gli alunni di tre scuole elementari di Colonia vengono accompagnati nell’apprendimento e nello sviluppo delle proprie competenze bilingui, non solo per soddisfare bisogni tipici della comunicazione nel quotidiano, ma soprattutto per affrontare efficacemente compiti e attività didattiche proprie dell’educazione scolastica istituzionale. Il raggiungimento di tale scopo può essere garantito solamente da una didattica del plurilinguismo differenziata, che si basi su un’attenta considerazione delle diverse condizioni e requisiti per l’apprendimento bilingue degli alunni e che si serva di dati ottenuti tramite un’accurata diagnostica dello sviluppo delle abilità linguistiche in italiano e in tedesco per adeguare, regolare e potenziare l’offerta formativa. THE Cancello dei fiori: ANALYSIS OF BILITERACY SKILLS IN ITALIAN AND GERMAN IN PRIMARY SCHOOLS Through the teaching of and in the Italian and German languages, the pupils of three primary schools in Cologne are trained in learning and developing their bilingual skills, not only regarding the typical needs of everyday communication, but above all for successfully dealing with the tasks and teaching activities at school. This aim cab be achieved thanks to a diversified multilingual educational approach, based on the careful consideration of the conditions and requirements for bilingual learning and drawing on information obtained through an accurate analysis of the development of language skills in Italian and German in order to adjust, regulate and enhance the educational experience.

Publisher: name: Deutsche Mathematiker-Vereinigung

description: This note provides modern proofs of some classical results in algebraic topology, such as the James Splitting, the Hilton-Milnor Splitting, and the metastable EHP sequence. We prove fundamental splitting results \begin{align*} \Sigma \Omega \Sigma X &\simeq \Sigma X \vee (X\wedge \Sigma\Omega \Sigma X) \\ \intertext{and} \Omega(X \vee Y) &\simeq \Omega X\times \Omega Y\times \Omega \Sigma(\Omega X \wedge \Omega Y) \end{align*} in the maximal generality of an $\infty$-category with finite limits and pushouts in which pushouts squares remain pushouts after basechange along an arbitrary morphism (i.e., Mather's Second Cube Lemma holds). For connected objects, these imply the classical James and Hilton-Milnor Splittings. Moreover, working in this generality shows that the James and Hilton-Milnor splittings hold in many new contexts, for example in: elementary $ \infty $-topoi, profinite spaces, and motivic spaces over arbitrary base schemes. The splitting results in this last context extend Wickelgren and Williams' splitting result for motivic spaces over a perfect field. We also give two proofs of the metastable EHP sequence in the setting of $ \infty $-topoi: the first is a new, non-computational proof that only utilizes basic connectedness estimates involving the James filtration and the Blakers-Massey Theorem, while the second reduces to the classical computational proof.

description: Cyber human interaction is a broad term encompassing the range of interactions that humans can have with technology. While human interaction with fixed and mobile computers is well understood, the world is on the cusp of ubiquitous and sustained interactions between humans and robots. While robotic systems are intertwined with computing and computing technologies, the word robot here describes technologies that can physically affect and in turn be affected by their environments which includes humans. This chapter delves into issues of cyber human interaction from the perspective of humans interacting with a subset of robots known as assistive robots. Assistive robots are robots designed to assist individuals with mobility or capacity limitations in completing everyday activities, commonly called instrumental activities of daily living. These range from household chores, eating or drinking to any activity with which a user may need the daily assistance of a caregiver to complete. One common type of assistive robot is the wheelchair mounted robotic arm. This device is designed to attach to a user's wheelchair to allow him or her to complete their activities independently. In short, these devices have sensors that allow them to sense and process their environment with varying levels of autonomy to perform actions that benefit and improve the well-being of people with capability limitations or disabilities. While human robot interaction is a popular research topic, not much research has been dedicated with regard to individual with limitations. In this chapter, we provide an overview of assistive robotic devices, discuss common methods of user interaction, and the need for an adaptive compensation framework to support potential users in regaining their functional capabilities.

Decompositions of Derived Categories of Gerbes and of Families of Brauer-Severi Varieties

description: It is well known that the category of quasi-coherent sheaves on a gerbe banded by a diagonalizable group decomposes according to the characters of the group. We establish the corresponding decomposition of the unbounded derived category of complexes of sheaves with quasi-coherent cohomology. This generalizes earlier work by Lieblich for gerbes over schemes whereas our gerbes may live over arbitrary algebraic stacks. By combining this decomposition with the semi-orthogonal decomposition for a projectivized vector bundle, we deduce a semi-orthogonal decomposition of the derived category of a family of Brauer-Severi varieties whose components can be described in terms of twisted sheaves on the base. This reproves and generalizes a result of Bernardara.

description: We rederive in a simplified version the Lehmann-Sommers eigenvalue distribution for the Gaussian ensemble of asymmetric real matrices, invariant under real orthogonal transformations, as a basis for a detailed derivation of a Pfaffian generating functional for $n$-point densities. This produces a simple free-fermion diagram expansion for the correlations leading to quaternion determinants in each order n. All will explicitly be given with the help of a very simple symplectic kernel for even dimension $N$. The kernel is valid both for complex and real eigenvalues and describes a deep connection between both. A slight modification by an artificial additional Grassmannian solves also the more complicated odd-$N$ case. As illustration we present some numerical results in the space $\mathbb{C}^n$ of complex eigenvalue $n$-tuples.

description:
Racism is a public health problem. Systems, structures, policies, and practices perpetuate a culture built on racism. Institutional reform is needed to promote antiracism. This article describes 1) a tool used to develop an equity action and accountability plan (EAAP) that promotes antiracism in the Department of Health Behavior at the University of North Carolina at Chapel Hill's Gillings School of Global Public Health, 2) strategies that were developed, and 3) short-term outcomes and lessons learned. A study coordinator, not affiliated with the Department of Health Behavior, was hired to collect qualitative data that documented the lived experiences of students and alumni of color (ie, racial and ethnic minority students) over time in the department. Seeking action from faculty and departmental leadership, students engaged in collective organizing covered the department chair's office door with notes describing microaggressions, and visited faculty one-on-one to demand action. In response, 6 faculty members volunteered to form the Equity Task Force (ETF) to explicitly address students' concerns. The ETF identified priority areas for action based on 2 student-led reports, gathered resources from other institutions and the public health literature, and examined departmental policies and procedures. The ETF drafted the EAAP, solicited feedback, and revised it according to 6 priority strategies with actionable steps: 1) transform culture and climate, 2) enhance teaching, mentoring, and training, 3) revisit performance and evaluation of faculty and staff, 4) strengthen recruitment and retention of faculty of color, 5) increase transparency in student hiring practices and financial resources, and 6) improve equity-oriented research practices. This planning tool and process can be used by other institutions to achieve antiracist reform.
Gravitational Radiation from Plunging Orbits - Perturbative Study -

description: Numerical relativity has recently yielded a plethora of results about kicks from spinning mergers which has, in turn, vastly increased our knowledge about the spin interactions of black hole systems. In this work we use black hole perturbation theory to calculate accurately the gravitational waves emanating from the end of the plunging stage of an extreme mass ratio merger in order to further understand this phenomenon. This study focuses primarily on spin induced effects with emphasis on the maximally spinning limit and the identification of possible causes of generic behavior. We find that gravitational waves emitted during the plunging phase exhibit damped oscillatory behavior, corresponding to a coherent excitation of quasi-normal modes by the test particle. This feature is universal in the sense that the frequencies and damping time do not depend on the orbital parameters of the plunging particle. Furthermore, the observed frequencies are distinct from those associated with the usual free quasi-normal ringing. Our calculation suggests that a maximum in radiated energy and momentum occurs at spin parameters equal to $a/M=0.86$ and $a/M=0.81$, respectively for the plunge stage of a polar orbit. The dependence of linear momentum emission on the angle at which a polar orbit impacts the horizon is quantified. One of the advantages of the perturbation approach adopted here is that insight into the actual mechanism of radiation emission and its relationship to black hole ringing is obtained by carefully identifying the dominant terms in the expansions used.

description: In order to allow for a comparison with the measurements from other antenna systems, the voltage power spectral density measured by the Radio and Plasma waves receiver (RPW) on board Solar Orbiter needs to be converted into physical quantities that depend on the intrinsic properties of the radiation itself.The main goal of this study is to perform a calibration of the RPW dipole antenna system that allows for the conversion of the voltage power spectral density measured at the receiver's input into the incoming flux density. We used space observations from the Thermal Noise Receiver (TNR) and the High Frequency Receiver (HFR) to perform the calibration of the RPW dipole antenna system. Observations of type III bursts by the Wind spacecraft are used to obtain a reference radio flux density for cross-calibrating the RPW dipole antennas. The analysis of a large sample of HFR observations (over about ten months), carried out jointly with an analysis of TNR-HFR data and prior to the antennas' deployment, allowed us to estimate the reference system noise of the TNR-HFR receivers. We obtained the effective length of the RPW dipoles and the reference system noise of TNR-HFR in space, where the antennas and pre-amplifiers are embedded in the solar wind plasma. The obtained $l_{eff}$ values are in agreement with the simulation and measurements performed on the ground. By investigating the radio flux intensities of 35 type III bursts simultaneously observed by Solar Orbiter and Wind, we found that while the scaling of the decay time as a function of the frequency is the same for the Waves and RPW instruments, their median values are higher for the former. This provides the first observational evidence that Type III radio waves still undergo density scattering, even when they propagate from the source, in a medium with a plasma frequency that is well below their own emission frequency.
IL CONTRIBUTO DELL’ITALIANO AL LESSICO LUDICO DEL TURCO DI TURCHIA
Creators: name: Manzelli, Gianguido
Publisher: name: Italiano LinguaDue
Year: 2021

description: L’articolo ha lo scopo di studiare gli elementi lessicali turchi nel campo semantico dei giochi di società e d’azzardo supposti essere prestiti dall’italiano o da altre varietà italo-romanze (come il veneziano e il genovese). Sono stati esaminati venticinque prestiti e ciò che è emerso dallo studio è un problema endemico per quel che riguarda i prestiti occidentali in turco, cioè il complicato rapporto linguistico fra il greco e l’italiano nell’Impero Ottomano (gran parte dei termini è databile al XIX secolo). Questo fatto rende abbastanza difficile stabilire quale sia la vera fonte immediata di molti prestiti. Altre lingue, inoltre, come il francese e il giudeo-spagnolo, sono coinvolte perché gli abitanti di Istanbul e Smirne erano molto spesso plurilingui e non meno di 4-5 lingue devono essere tenute in conto per quel che riguarda il loro repertorio linguistico. L’autore considera i prestiti turchi esaminati una testimonianza dell’esistenza di una lingua non scritta che può essere chiamata italo-levantino, una varietà di italiano che ebbe un particolare sviluppo nella società plurilingue dell’ultimo secolo dell’Impero Ottomano. The Italian contribution to the Turkish lexicon of parlour games and gambling This paper scrutinizes Turkish lexical items in the semantic field of parlour games and gambling assumed to be borrowings from Italian or other Italo-Romance varieties (such as Venetian or Genoese). Twenty-five loanwords were examined in this study which shed light on the endemic problem as far as Western borrowings in Turkish are concerned, i.e. the complicated linguistic relationship between Greek and Italian in the Ottoman Empire (of the items can be dated to the 19th century). This makes it quite difficult to establish the real source of many loanwords. Moreover, other languages such as French and Judeo-Spanish, are involved because the inhabitants of Istanbul and Smyrna were very often plurilingual, and no less than 4-5 languages made up their linguistic repertoires. The author considers the Turkish lexical items analyzed as a testimony of the existence of an unwritten language which can be called Italo-Levantine, a variety of Italian which had a particular development in the last century of the Ottoman Empire.

In this new approach the treatment of the 3N Faddeev equation becomes essentially as simple as the treatment of the two-body Lippmann-Schwinger equation. Very good agreement of the new and old approaches in the application to nucleon-deuteron elastic scattering and the breakup reaction is found.

description: We determine explicitly and discuss in detail the effects of the joint presence of a longitudinal and a transversal (random) magnetic field on the phases of the Random Energy Model (REM) and its hierarchical generalization, the GREM. Our results extent known results both in the classical case of vanishing transversal field and in the quantum case for vanishing longitudinal field. Following Derrida and Gardner, we argue that the longitudinal field has to be implemented hierarchically also in the Quantum GREM. We show that this ensures the shrinking of the spin glass phase in the presence of the magnetic fields as also expected for the Quantum Sherrington-Kirkpatrick model.

VARIETÀ IN CONTATTO IN UN MANOSCRITTO SECENTESCO DI NOVARA DI SICILIA

description: Un testo di osservazione, all’interno di uno dei dialetti galloitalici della Sicilia che ha avuto una elaborazione scritta assai modesta, è un manoscritto agiografico secentesco sulla Vita di suor Cristina da Gesù (1689). Il manoscritto è un testimone prezioso, relativamente antico, scritto in italiano, in una varietà di lingua fortemente marcata sul piano diastratico: abbondano i prestiti dal dialetto, galloitalico e siciliano, integrati sul piano fono-morfologico, e le interferenze ai livelli delle strutture grammaticali, fonologiche, lessicali, semantico-pragmatiche. Benché galloitalici, anche questi testi presentano, in misura diversa, ampi influssi della lingua, come tutta la letteratura novarese in genere, dal momento che a Novara il contatto con il siciliano è sempre stato asimmetrico per il maggior prestigio e l’importanza socioeconomica e culturale dominante del siciliano. Nel corso dei secoli i rapporti tra i tre codici (italiano/siciliano vs. siciliano) sono stati principalmente unidirezionali, il galloitalico è sempre stato la lingua replica accogliendo gli influssi della lingua modello. Di questi fatti linguistici si darà, sulla base del modello weinreichiano di Languages in contact e quello gusmaniano dell’interlinguistica, una descrizione a tutti i livelli della lingua. Languages in contact in a seventeenth-century manuscript from Novara di Sicilia This paper features a detailed description and analysis of a seventeenth-century hagiographical manuscript, Vita di suor Cristina da Gesù, written in one of the Gallo-Italic dialects of Sicily, which had a very modest written elaboration. The manuscript is a valuable example of a relatively old work written in Italian, in a single language strongly marked on a diastratic level: there are a lot of borrowings from the Gallo-Italic and the Sicilian dialects, integrated on a phono-morphological level, and interference at the levels of grammatical, phonological, lexical, semantic-pragmatic structures. Although Gallo-Italic, this text also presents, in varying degrees, a wide range of influences from the Sicilian language, like all Novara literature in general, since in Novara contact with Sicilian was always asymmetrical due to greater prestige and the socio-economic and cultural importance of Sicilian. Over the centuries, the relationship between the three codes (Italian/Sicilian vs Sicilian) was unidirectional, Gallo-Italic has always been the replica language, accepting the influences of the model language. This paper describes these linguistic details at all levels of the language based on the Weinreichian model of Languages ​​in contact and of the Gusmanian model of the interlinguistics.

However the program may be seen as rather tricky and one may not be convinced about its correctness. This paper explains the program in a declarative way, and provides proofs of its correctness and completeness. The specification and the proofs are declarative, i.e. they abstract from any operational semantics. The specification is approximate, it is unnecessary to describe the program's semantics exactly. Despite the program works on non-ground terms, this work employs the standard semantics, based on logical consequence and Herbrand interpretations. Another purpose of the paper is to present an example of precise declarative reasoning about the semantics of a logic program. Under consideration in Theory and Practice of Logic Programming (TPLP).

description: We investigate the relations among the stellar continuum-subtracted 8 micron polycyclic aromatic hydrocarbon (PAH 8 micron) emission, 24 micron hot dust emission, and 160 micron cold dust emission in fifteen nearby face-on spiral galaxies in the Spitzer Infrared Nearby Galaxies Survey sample. The relation between PAH 8 and 24 micron emission measured in ~2 kpc regions is found to exhibit a significant amount of scatter, and strong spatial variations are observed in the (PAH 8 micron)/24 micron surface brightness ratio. In particular, the (PAH 8 micron)/24 micron surface brightness ratio is observed to be high in the diffuse interstellar medium and low in bright star-forming regions and other locations with high 24 micron surface brightness. PAH 8 micron emission is found to be well-correlated with 160 micron emission on spatial scales of ~2 kpc, and the (PAH 8 micron)/160 micron surface brightness ratio is generally observed to increase as the 160 micron surface brightness increases. These results suggest that the PAHs are associated with the diffuse, cold dust that produces most of the 160 micron emission in these galaxies, and the variations in the (PAH 8 micron)/160 micron ratio may generally be indicative of either the intensity or the spectrum of the interstellar radiation field that is heating both the PAHs and the diffuse interstellar dust.

description: One of the earliest proposed phase transitions beyond the Landau-Ginzburg-Wilson paradigm is the quantum critical point separating an antiferromagnet and a valence-bond-solid on a square lattice. The low energy description of this transition is believed to be given by the 2+1 dimensional CP(1) model -- a theory of bosonic spinons coupled to an abelian gauge field. Monopole defects of the gauge field play a prominent role in the physics of this phase transition. In the present paper, we use the state-operator correspondence of conformal field theory in conjunction with the 1/N expansion to study monopole operators at the critical fixed point of the CP(N-1) model. This elegant method reproduces the result for monopole scaling dimension obtained through a direct calculation by Murthy and Sachdev. The technical simplicity of our approach makes it the method of choice when dealing with monopole operators in a conformal field theory.

description: Little-Parks oscillations of a hollow superconducting cylinder are of interest for flux-driven topological superconductivity in single Rashba nanowires. The oscillations are typically symmetric in the orientation of the applied magnetic flux. Using double InAs nanowires coated by an epitaxial superconducting Al shell which, despite the non-centro-symmetric geometry, behaves effectively as one hollow cylinder, we demonstrate that a small misalignment of the applied parallel field with respect to the axis of the nanowires can produce field-asymmetric Little-Parks oscillations. These are revealed by the simultaneous application of a magnetic field perpendicular to the misaligned parallel field direction. The asymmetry occurs in both the destructive regime, in which superconductivity is destroyed for half-integer quanta of flux through the shell, and in the non-destructive regime, where superconductivity is depressed but not fully destroyed at these flux values.

description: This thesis describes a study of six North American, dioicous Brachytheeium species possessing a rough seta. The phenetic variability of the six species was analysed in order to clarify the relationships, between species and to provide .simpler, more reliable means of identifying specimens. As a consequence of this investigation, the taxonomic identities of B. asperrimum (Mitt. ex. C. Muell.) Sull. and B. frigidum (C. Muell.) Besch, have been established through numerical analyses of the variation in the gametophytic features of the two species. Two types of analyses were used: a principal components analysis and a cluster analysis. The phenetic variation and habitat specificity of each species were analysed and documented and synonymy and ranges presented. A. test of the features considered diagnostic for the two species has been performed and the results of this test used to devise a reliable key. The relationships of the two species to the other North American dioicous species possessing rough setae were determined using a principal components analysis and. a cluster analysis. B. asperrimum (Mitt. ex. C. Muell.). Sull is shown to be closely related to B. bolanderi (Lesq.) Jaeg. and Sauerb.. B. frigidum (C. Muell.) Besch. is shown to be closely related to B. rivulare B.S.G. and B. nelsonii Grout. A dendrogram and discussion of the hypothetical, cladistic relationships of the six species are provided.

description: Nel presente lavoro verranno considerate le interrelazioni tra differenti tipi di comunità albanofone in territorio italiano; in particolare analizzerò alcune dinamiche del contatto linguistico e della sostituzione di codice sulla base dell’esempio dato dall’albanese parlato in una comunità della Puglia - Chieuti - e in tre del Molise - Campomarino, Portocannone e Ururi. Tali comunità saranno analizzate in quanto terreno di intersezione di minoranze storiche e nuove minoranze. Dai risultati di indagini precedenti emerge che ci troviamo di fronte a un duplice shift: dall’arbëresh all’italiano nel caso delle minoranze storiche, e dall’albanese all’italiano nel caso delle nuove minoranze. In entrambe le situazioni tale sostituzione di codice è inestricabilmente connessa a questioni di identità. Tali dati, ricavati da autodichiarazioni dei parlanti, verranno comparati con dati di parlato spontaneo; in particolare, analizzando il discorso dei bilingui, sia degli Arbëreshë sia degli Albanesi in contesto italofono: si verificherà se i dati linguistici ricavati in un contesto pervaso da contatto interlinguistico confermano il quadro macro-sociolinguistico sopra delineato. Old and new minorities in contact. Identity dynamics and linguistic outcomes Different relationships among Albanian communities in Italy, that is old minorities, the Arbëreshë from one side and new Albanian minorities from the other, are analyzed in this study. In particular, processes of language contact and shifts based on the examples of some Albanian communities in the Italian regions of Molise and Puglia are investigated. Previous data indicates that a twofold shift is going on: from Arbëresh to Italian and from Albanian to Italian, two processes that are strictly connected to question of identity. These results are compared to bilingual speech data, verifying whether language contact phenomena prove that the macro-sociolinguistic setting is characterized by different degrees of language obsolescence.

description: When we consider the application layer of networked infrastructures, data and control flow are important concerns in distributed systems integration. Modularity is a fundamental principle in software design, in particular for distributed system architectures. Modularity emphasizes high cohesion of individual modules and low coupling between modules. Microservices are a recent modularization approach with the specific requirements of independent deployability and, in particular, decentralized data management. Cohesiveness of microservices goes hand-in-hand with loose coupling, making the development, deployment, and evolution of microservice architectures flexible and scalable. However, in our experience with microservice architectures, interactions and flows among microservices are usually more complex than in traditional, monolithic enterprise systems, since services tend to be smaller and only have one responsibility, causing collaboration needs. We suggest that for loose coupling among microservices, explicit control-flow modeling and execution with central workflow engines should be avoided on the application integration level. On the level of integrating microservices, data-flow modeling should be dominant. Control-flow should be secondary and preferably delegated to the microservices. We discuss coupling in distributed systems integration and reflect the history of business process modeling with respect to data and control flow. To illustrate our recommendations, we present some results for flow-based programming in our Industrial DevOps project Titan, where we employ flow-based programming for the Industrial Internet of Things.

description: Superconductors often contain quantized microscopic whirlpools of electrons, called vortices, that can be modeled as one-dimensional elastic objects. Vortices are a diverse playground for condensed matter because of the interplay between thermal fluctuations, vortex-vortex interactions, and the interaction of the vortex core with the three-dimensional disorder landscape. While vortex matter has been studied extensively, the static and dynamic properties of an individual vortex have not. Here we employ magnetic force microscopy (MFM) to image and manipulate individual vortices in detwinned, single crystal YBa2Cu3O6.991 (YBCO), directly measuring the interaction of a moving vortex with the local disorder potential. We find an unexpected and dramatic enhancement of the response of a vortex to pulling when we wiggle it transversely. In addition, we find enhanced vortex pinning anisotropy that suggests clustering of oxygen vacancies in our sample and demonstrates the power of MFM to probe vortex structure and microscopic defects that cause pinning.

description: Over the past two decades, monarch butterfly populations have been declining. This decline has been partly attributed to the extensive loss of breeding habitat through the reduction of common milkweed (Asclepias syriaca, the larval host plant) through herbicides. While the decline of milkweed has been well documented in the US, less is known about its decline in Canada. To take a first step in quantifying its potential decline, we compared roadside milkweed abundance at sites around Ottawa, Ontario, Canada in 2018, to a county-wide estimate of milkweed abundance in 1943 and 1944. We also evaluated the effect of roadside characteristics on milkweed abundance at these sites. Current milkweed density in the Ottawa region is 33–86% lower than it was 75 years ago. We found milkweed at 67% of our 100 sites and found less milkweed at sites with a higher number of lanes in the road adjacent to the roadside. Interestingly, mowing indices were not significant predictors of milkweed abundance. Here we document the first quantitative evidence for milkweed decline over the past 75 years in Canada, which has likely contributed to the decline of breeding monarchs in Canada.

description: We analyze atomic photoelectron momentum distributions induced by bichromatic and monochromatic laser fields within the strong field approximation (SFA), separable Coulomb-Volkov approximation (SCVA), and ab initio treatment. We focus on the high frequency regime -- the smallest frequency used is larger than the ionization potential of the atom. We observe a remarkable agreement between the ab initio and velocity gauge SFA results while the velocity gauge SCVA fails to agree. Reasons of such a failure are discussed.

description: La globalizzazione ha come conseguenza un intenso flusso migratorio e una moltiplicazione di comunità diasporiche in vari centri del mondo (Vertovec, 2007). Questo lavoro focalizza l´attenzione sull’aspetto linguistico dell’immigrazione straniera, in particolare riferimento alle lingue immigrate. Se all’inizio del fenomeno migratorio poca attenzione veniva prestata, sia in Italia che in Europa, ad una ricognizione delle lingue parlate dagli immigrati, sul loro stato e uso nei paesi di migrazione (Barni, 2004: 8), l’ingresso degli stranieri, sempre più numerosi ha spinto gli esperti nel campo della linguistica ad approfondire ricerche nell’ambito delle lingue degli immigrati. Questo contributo focalizza la propria attenzione sul camfranglais, una delle lingue parlate dai Camerunensi. Con la migrazione dei camerunesi in Italia, il contatto del camfranglais con l’italiano dà origine a una nuova lingua, diversa dal camfranglais usato dai camerunensi in Camerun. Migration, languages in contact and the birth of new languages: the case of Camfranglais Globalization has led to an intense migratory flow and a multiplication of diasporic communities in various centers of the world (Vertovec, 2007). The present work focuses on the linguistic aspect of immigration, particularly with regard to immigrants’ languages. At the nascent stage of the contemporary migratory phenomenon, little attention has been paid - both in Italy and in Europe - to the analysis of the status and uses of the languages spoken by immigrants in the countries of immigration (Barni, 2004: 8). However, the increasing wave of immigration prompted more experts in the field of linguistics to deepen research on the immigrants’ languages. This contribution focuses on Camfranglais, one of the languages spoken by Cameroonians. With the migration of Cameroonians to Italy, the contact of Camfranglais with the Italian language gives birth to a new language, which carries, in the new setting, new characteristics and functions.

description: We report the observation of above-threshold dissociation of a multielectron molecular system, Na$_2^+$. The process is due to continuum-continuum transitions in a field-dressed molecular continuum. Three well resolved fragmentation channels with different kinetic energy release patterns have been detected, of which, two are associated with ordinary photodissociation via light-induced potentials into Na(3s) + Na$^+$ and Na(3p) + Na$^+$, and one with continuum-continuum transitions and above-threshold dissociation into Na(3p) + Na$^+$. We show that when we dress this molecule with a field whose intensity is ~3 x 10$^{12}$ W/cm$^2$, above-threshold dissociation prevails over other processes, such as field-ionization followed by Coulomb explosion.

description: PLANUNGSUNTERSTÜTZUNG DURCH DIE ANALYSE RÄUMLICHER PROZESSE MITTELS COMPUTERSIMULATIONEN. Erst wenn man – zumindest im Prinzip – versteht, wie eine Stadt mit ihren komplexen, verwobenen Vorgängen im Wesentlichen funktioniert, ist eine sinnvolle Stadtplanung möglich. Denn jede Planung bedeutet einen Eingriff in den komplexen Organismus einer Stadt. Findet dieser Eingriff ohne Wissen über die Funktionsweise des Organismus statt, können auch die Auswirkungen nicht abgeschätzt werden. Dieser Beitrag stellt dar, wie urbane Prozesse mittels Computersimulationen unter Zuhilfenahme so genannter Multi-Agenten-Systeme und Zellulärer Automaten verstanden werden können. von

description: We present a novel model for the problem of ranking a collection of documents according to their semantic similarity to a source (query) document. While the problem of document-to-document similarity ranking has been studied, most modern methods are limited to relatively short documents or rely on the existence of "ground-truth" similarity labels. Yet, in most common real-world cases, similarity ranking is an unsupervised problem as similarity labels are unavailable. Moreover, an ideal model should not be restricted by documents' length. Hence, we introduce SDR, a self-supervised method for document similarity that can be applied to documents of arbitrary length. Importantly, SDR can be effectively applied to extremely long documents, exceeding the 4,096 maximal token limits of Longformer. Extensive evaluations on large document datasets show that SDR significantly outperforms its alternatives across all metrics. To accelerate future research on unlabeled long document similarity ranking, and as an additional contribution to the community, we herein publish two human-annotated test sets of long documents similarity evaluation. The SDR code and datasets are publicly available.
