description: Der Beitrag berichtet über eine praktikable Lösung zur Umsetzung des Forschungsdatenmanagements (FDM), welche den Anforde­rungen des mittlerweile abgeschlossenen, europäisch-sächsischen Verbundprojekts AMTwin folgt. AMTwin zielte auf die Entwicklung eines digitalen Zwillings für additiv gefertigte Komponenten ab. Konkret wurden Berechnungs­modelle für das Materialverhalten von Titanteilen aus Ti6Al4V und für die Prozessstabilität bei deren Herstellung mittels Selektivem Lasersintern (SLM) entwickelt. Da die Modellbildung datenbasiert erfolgte, war für den reibungslosen Datenaustausch und schließ­lich für den Projekterfolg ein praktikables FDM zwingend. Der Datenaustausch im interdisziplinären Verbundprojekt erfolgte la­borübergreifend entlang der untersuchten Prozesskette von der Rohstoffcharakterisierung, über den Formgebungsprozess, die Gefügeanalyse, die Prüfung der mechanischen Bauteileigenschaf­ten bis hin zur Datenanalyse und zur Entwicklung der Simulations­modelle. Der Beitrag zeigt zunächst, dass die Einhaltung der FAIR-Prin­zipien nicht nur die Vorgabe eines Ideals sondern die technische Voraussetzung für den Datenaustauch und die Datenintegration darstellt. Die FAIR-Prinzipien wurden u.a. durch die Einführung einer fachspezifischen Ontologie zusammen mit einem Synonym­wörterbuch umgesetzt, um die Domänenspezifika der beteiligten Partner bei der Generierung eines Gesamtdatensatzes zur be­trachteten Prozesskette zu berücksichtigen. Der Beitrag fasst die notwendigen Entwicklungen sowohl bei den einzelnen Fachdomä­nen als auch im Projektkonsortium zusammen, um zum übergeord­neten FDM zu gelangen. Dies beinhaltet u.a. ein Id-Management der erstellten Probekörper. Der erstellte Gesamtdatensatz wurde schließlich umfangreichen Analysen zugeführt, um einerseits Erkenntnisse zu Fertigungspro­zess und Materialverhalten zu gewinnen und um andererseits die Modellbildung zu unterstützen. Es wird gezeigt, wie Prozessketten-übergreifende Datenanalysen unmittelbar aus dem FDM möglich werden. In der Regel werden Ergebnisse aus Forschungsprojekten publi­ziert. In AMTwin umfasste dies, neben der Veröffentlichung neuer Erkenntnisse in den Materialwissenschaften und der Produktions­technik sowie zu numerischen Verfahren, auch den im Verbundpro­jekt generierten Gesamtdatensatz. Es wird veranschaulicht, wie der Datensatz aus dem FDM direkt in eine Open-Access-Publikation geführt werden kann. Abschließend zieht dieser Beitrag ein Fazit zur erreichten Usabi­lity der entwickelten Lösung und leitet Schwerpunkte des weiteren Ausbaus ab.

description: Tubular aggregate myopathy (TAM) is one of a cluster of rare genetic diseases, together with Stormorken syndrome and York platelet syndrome (YPS). The aetiology of these diseases is the mutation in one of two key proteins, ORAIi and STIMÍ. Both proteins are the principai protagonists in Store-Operated Calcium Entry (SOC Entry), a mechanism of calcium homeostasis. Up to now, no mouse model has been designed bearing a luminal STIM1 mutation associated with the clinical diagnosis of any of the diseases. A mouse model bearing 11 15F mutation, which is associated with TAM and YPS, is extremely needed, to guarantee the effectiveness of putative treatment in patients bearing luminal STIM1 mutations. This thesis project demonstrates that the KI-STIM" mouse model is valid for both TAM and YPS, confirming at the same time the hypothesis of some authors, who defend that TAM, Stormorken, and YPS are indeed the spectra of the same disease whose symptoms differences are base in the position and effect of the point mutation.

description: Il presente lavoro di ricerca intende colmare una lacuna tuttora riscontrabile nella ricezione in lingua italiana dell'opera poetica dell'autore francese Robert Desnos (Parigi, 1900-1945). Sulla scia della semantica seriale proposta da Henri Meschonnic, della traduzione intesa come opera a tutti gli effetti e non mero compendio all'originale sotto gli auspici di Franco Buffoni e secondo la visione di Lawrence Venuti, con il superamento della pretesa invisibilità del traduttore, abbiamo proposto una prima traduzione integrale in lingua italiana della raccolta poetica postuma Destinée arbitraire (1975), che abbraccia l'intera produzione del poeta, e presenta una sezione dedicata ai poemi in gergo. La traduzione, corredata di un apparato di note, è preceduta da una riflessione teorica sulla traduzione del testo e sulla poetica di Desnos. L'inchiesta condotta nel mondo delle avanguardie d'inizio Novecento si è rivelata necessaria, nella misura in cui l'autore ne rappresenta, a tratti, il fulcro, e offre la sua poesia militante prima all'anti-poesia di matrice surrealista, poi alla lotta dei repubblicani spagnoli e, infine, alla causa della resistenza. L'analisi dell'architettura verbale ha evidenziato alcuni procedimenti compositivi in consonanza con il campo musicale e, in particolare, la nozione di sincope, che l'autore, critico musicale e cinematografico, oltre che d'arte in generale, sfrutta per mantenere viva l'attenzione del lettore ed interrompere una serie di variazioni su uno stesso tema, nonché alcune strutture generative in relazione al principio del parallelismo. Ancora come sovversione del linguaggio vanno letti i défigement e le déproverbialisation che, innestando dei meccanismi di rottura in modelli ritmici consolidati, contribuiscono all'azione di demistificazione delle convenzioni e dei pregiudizi, portata avanti, con coerenza e costante humour, dall'autore, fino alla lotta all'oppressione nazista, che lo vedrà soccombere nel campo di Terezin.

description: We study the Krapivsky-Redner (KR) network growth model but where new nodes can connect to any number of existing nodes, $m$, picked from a power-law distribution $p(m)\sim m^{-α}$. Each of the $m$ new connections is still carried out as in the KR model with probability redirection $r$ (corresponding to degree exponent $γ_{\rm KR}=1+1/r$, in the original KR model). The possibility to connect to any number of nodes resembles a more realistic type of growth in several settings, such as social networks, routers networks, and networks of citations. Here we focus on the in-, out-, and total-degree distributions and on the potential tension between the degree exponent $α$, characterizing new connections (outgoing links), and the degree exponent $γ_{\rm KR}(r)$ dictated by the redirection mechanism.

description: Das Projekt NFDI4Ing zur Nationalen Forschungsdateninfrastruktur für die Ingenieurwissenschaften orientiert sich in seiner praktischen Arbeit mit der Fachcommunity an der Systematik der Fachkollegien der Deutschen Forschungsgemeinschaft (DFG) und bildet anhand die­ser so genannte Community-Cluster. Die Technische Universität Dres­den in Zusammenarbeit mit dem Deutschen Zentrum für Luft- und Raumfahrt (DLR) und der Sächsischen Landesbibliothek — Staats- und Universitätsbibliothek Dresden (SLUB) koordinieren das fachlich sehr heterogene Community-Cluster CC-44, welches neben den Verkehrs­wissenschaften Disziplinen wie Automatisierung und Robotik, System­technik, Elektrotechnik und Informatik umfasst (DFG 407, 408 und 409). Die Ziele der Arbeit mit der Fachcommunity umfassen die Einbe­ziehung fachspezifischer Anforderungen an das Forschungsdaten­management in die Arbeit in NFDI4Ing, den fachlichen Austausch zu Best-Practice Beispielen innerhalb der Community, die Sicherstel­lung nutzer:innen-naher Entwicklungen in NFDI4Ing durch die enge Zusammenarbeit mit der Community in allen Schritten sowie die Weitergabe von in NFDI4Ing erarbeiteten Ergebnissen und Diensten an die Fachcommunity. Der Vortrag berichtet aus der praktischen Arbeit mit dieser Fachcommunity: • Wie wird diese erfasst, wie werden relevante Multiplikatoren identifiziert? • Wie werden spezifische Handlungsbedarfe herausgearbeitet? • Welche werden Arbeitsaufgaben daraus abgeleitet? • Wie werden Veranstaltungen inhaltlich und strukturell konzipiert? Es wird zudem beschrieben, welche konkreten Handlungsfel­der sich für die Communityarbeit ergeben und wie eines dieser Handlungsfelder, „Datenstandards und – schnittstellen“ konkret in einem parallel verlaufenden top-down und bottom-up Prozess adressiert wird: Dieser wird, zur Unterstützung sowohl der Schaffung von Best- Practice Beispielen als auch von generischen Ansätzen, aus den Verkehrswissenschaften heraus einen Use Case zur systematischen Erfassung, Beschreibung und Verknüpfung von domänenspezifischen Datentypen etablieren. Hierzu soll zunächst mit Fachexpert:innen eine gemeinsame Übersicht über die domänenspezifisch verwen­deten Typologien von Daten geschaffen werden. Anschließend wird erarbeitet, wie diese Daten zweckmäßig beschrieben und welche Standards dabei eingesetzt werden können, um diese nachfolgend zu veröffentlichen. So soll ein fachspezifischer aber auch ein allge­mein nutzbarer Workflow als systematischer Prozess vom Erzeugen bis zum Veröffentlichen von Datensätzen beschrieben werden, wel­cher entlang des Forschungsdatenlebenszyklus mit nachnutzbaren Standards ausgestattet ist (Ontologien, Vokabulare etc.).

description: Questa tesi fornisce per la prima volta negli studi traduzione italiana e commento storico della Pro Quattuor del retore d'età antonina Elio Aristide, lunghissima orazione con la quale il suo autore si prefigge l'obiettivo di difendere Pericle, Cimone, Milziade e Temistocle dalle accuse di servilismo loro riservate nel Gorgia platonico. Il lavoro appronta un resoconto puntuale dei riferimenti a eventi politico-militari della storia greca di V e IV sec. a.C. disseminati nel testo e discute la possibilità della valorizzazione in chiave apologetica, da parte del retore, di tradizioni storiografiche, dossografiche, biografiche elleniche per noi perdute ma ancora vitali nel II sec. d.C.: con questa duplice finalità, viene assecondato un versante di ricerca che fino ad oggi non ha trovato riscontro alcuno nella pur striminzita letteratura prodotta su quest'opera, bollata spregiativamente nella critica del '900 come mero gioco letterario fine a sé stesso.

description: Rationale: Osteopontin (OPN) is a pleomorphic cytokine known to influence a wide range of immune cells; allergic asthma was previously associated with high circulating OPN levels. The aim was to evaluate OPN as a possible biomarker of immune activation in allergic patients belonging to two different ethnic groups: Caucasians and South-East Asians. B. Method: Serum OPN levels were measured by ELISA test in a series of 121 Italian adult patients affected by allergic asthma, allergic rhinitis, Hymenoptera venom allergy, food allergy, allergic contact dermatitis and IgE-mediated hypersensitivity to B-lactams. 116 healthy subjects served as controls. 576 ethnic Chinese subjects were recruited at the National University of Singapore as cross-sectional cohort of an epidemiological study on the national prevalence of allergic diseases, and OPN levels were detected by Luminex and ELISA assays. C. Results: In the Italian cohort, OPN levels were significantly higher in cases compared to controls (P=0.0010 by the Mann-Whitney test). Statistically higher OPN levels were found in asthma (P=0.0269) and food allergy (P=0.046) groups in comparison to controls. No significant differences were found (P=0.597) between Singaporeans with "lifetime asthma" (i.e., subjects presenting asthma at least once in their life) and healthy controls. However, a strong gender effect was shown, in both cases (P<0.0001) and controls (P<0.0001), with males presenting higher OPN levels in comparison to females. Consequently, the mRNA expression levels of OPN gene (SPP1) were checked with illumina chips in whole blood of males and females, and no differences were found. Several experiments with Western Blots were performed to verify if possible post-transcriptional/post-translational modifications of OPN could explain these findings

description: We generalize the ordinary Wess-Zumino model to the Bosonic-Fermionic noncommutative (BFNC) superspace and study its renormalization. In our previous work that can be regarded as the key foundation of the present paper, we have proved that the BFNC Wess-Zumino model with the real mass and interacting constant is one-loop renormalizable up to the second order of BFNC parameters. Based on the result obtained, in the present paper we modify the one-loop renormalizable BFNC Wess-Zumino model by generalizing the mass and interacting constant to complex numbers, introduce the U(1)_{R} R-symmetry and U(1)_Φ flavor symmetry in the modified model, analyze possible divergent operators in the effective action of the modified model by using the dimensional analysis method, and further give a new BFNC Wess-Zumino model that is renormalizable at all loops still up to the second order of BFNC parameters by imposing symmetries rather than doing a direct perturbative investigation.

description: Recently, a max-plus dual space fundamental solution semigroup for a class of difference Riccati equation (DRE) has been developed. This fundamental solution semigroup is represented in terms of the kernel of a specific max-plus linear operator that plays the role of the dynamic programming evolution operator in a max-plus dual space. In order to fully understand connections between this dual space fundamental solution semigroup and evolution of the value function of the underlying optimal control problem, a new max-plus primal space fundamental solution semigroup for the same class of difference Riccati equations is presented. Connections and commutation results between this new primal space fundamental solution semigroup and the recently developed dual space fundamental solution semigroup are established.

Vortrag

description: Viele Forschungseinrichtungen halten zentrale Tools, Policies und Services für FDM vor. Jedoch sind oft das Interesse und die Nutzung dieser von den Forschern oft gering ausgeprägt. Die Schaffung von Strukturen kann daher nur ein Baustein für erfolgreiches FDM sein. Multi-institutionelle Exzellenzcluster wie NeuroCure bewegen sich zwischen FDM-Strukturen unterschiedlicher Ausprägung und sind durch Fördergeber angehalten, Vorreiter im FDM-Bereich zu sein. Daraus ergeben sich Chancen für eine punktuelle Sensibilisierung und Selbstreflektion. Der Vortrag erläutert Konzepte für erfolgs­versprechende, nachhaltige Interaktionen mit Forschern durch Ein­bettung von FDM in offene Wissenschaften und Forschungsqualität: • Besuchsprogramm mit Selbstreflektion hinsichtlich offener Wissenschaft • Nutzung von Dimensions und OddPub für OpenData und Qua­litäts-Assessement • Aktive Unterstützung bei Zweitveröffentlichungen • Angebote - Automatische Screeningservice für Manuskripte und PrePrints • Kurze öffentliche Selbstverpflichtung zu FDM statt Forschung­daten-Policy • FDM-Kurzumfrage • Praktisches FDM einbinden in OpenScience/Transparenz- Workshops Dabei ist die Einbettung in Open Science, Transparenz und Quali­tätsaspekten erhält den FDM einen anderen Stellenwert. Mit wenig Aufwand läßt sich eine individuelle Publikationsanalyse gestalten, die die eigenen Praktiken hinsichtlich offener Wissenschaft und Data Sharing aufzeigt und als Vorlage für individuelle Empfehlun­gen dient. Durch strukturiertes, proaktives Handeln und dem Auf­zeigen von Verbesserungspotentialen ist eine nachhaltige Sensibili­sierung von Arbeitsgruppen für aktiveres FDM möglich.
Individual differences and their implications in educational and occupational outcomes

Subjects: Individual Differences

description: This thesis includes four studies focused on the role of Individual Differences in educational and occupational outcomes. These four studies were aimed to bridge gaps in the academic literature and to devise novel avenues for research. Chapter 1 introduces the concept and history of Individual Differences research. Chapter 1 also includes a summary of the milestones in Intelligence research history. Chapter 2 includes our first study, where we used two waves from a British longitudinal study to explore the changes in student Self-Competence and Task-Value during the primary to secondary school transition according to student’s verbal abilities. We conceptualized change as Difference Scores and as Residuals but none offered a reliable measure of change. In Chapter 3, we used the same sample to study the degree to which change in grades between ages 7 and 11 mediated the relation between verbal ability and changes in occupational aspirations between ages 11 and 14. However, we did not find evidence supporting the mediating role of grades change. Chapter 4 summarizes the highlights of personality history and frames our methodological approach to personality measures. In Chapter 5, we used Cohen’s d and Mahalanobis D to study personality differences at facet and domain level between four groups: heterosexual men, heterosexual women, homosexual men, and homosexual women. We found that homosexual participants did not always score as their heterosexual counterparts. Often, personality scores of homosexual participants shifted toward those of their opposite sex -e.g. homosexual men scoring more similar to heterosexual women than heterosexual men. In Chapter 6, we studied to which degree personality sex differences were feeding into the gendered nature of the labor market, this is, men tend to work in jobs related to Science, Technology, Engineering, and Mathematics (STEM), while women work in Non-STEM related occupations. We found little evidence supporting this hypothesis. However, there was some evidence suggesting that personality differences between occupational orientations (i.e. Prediger’s dimension of people vs. things) do resemble personality sex differences. Finally, Chapter 7 summarizes the key findings of these studies. Further implications and future research directions are also discussed in this last chapter.

description: Dynamic models are important tools for public health purposes; they allow esimaing the impact of diferent approaches and can be used for a populaion health improvement planning or to organize a response to an emerging public health issue. The aims of my thesis are to design, build, test, parameterized, and illustrated two dynamic models. One is a populaion-based model of Human Papilloma Virus (HPV) infecion natural history and vaccinaion; the other is an individual based model of tobacco control. Both models have been adapted to account for public health measure of prevenion and control. Also, both models can incorporate enough demographic data to adapt their outputs to speciic populaion, in which realisic intervenions are simulated. The model of HPV transmission and control has been adapted and parameterized to represent diferent populaions from both high- and low-middle-income countries, i.e. Sweden, Italy, US, and India, and diferent HPV types, i.e. 16,18, and 45. By contrast, the model of tobacco control has been designed to reproduce smoking behaviors and demography of the Italian populaion between year 2000 and 2013 and used to evaluate the efect of public health policy, e.g. smoking prevalence on the Italian populaion in year 2030. Both models are coded in C compuing language, according to high-performance programming standards, eicient data structures and algorithms, and opimizaion techniques to maximize the compuing eiciency. In my thesis, I have used the two models to predict the expected impact of selected public health intervenions both for HPV and cervical cancer control and for tobacco control. The outputs of each set of simulations have been analysed using advanced staisical methods/libraries, e.g. GNU Scieniic Library and sotware such as R (CRAN) and STATA. These predicions illustrate the potenial of using mathemaical model for assessing the efeciveness of selected prevenion and control measures.

description: In this paper we consider a fractional analogue of the Monge-Ampère operator. Our operator is a concave envelope of fractional linear operators of the form $ \inf_{A\in \mathcal{A}}L_Au, $ where the set of operators corresponds to all affine transformations of determinant one of a given multiple of the fractional Laplacian. We set up a relatively simple framework of global solutions prescribing data at infinity and global barriers. In our key estimate, we show that the operator remains strictly elliptic, which allows to apply known regularity results for uniformly elliptic operators and deduce that solutions are classical.

A max-plus dual space fundamental solution for a class of operator differential Riccati equations

Publisher: name: arXiv
Year: 2014
Subjects: subject: Optimization and Control (math.OC)

description: A new fundamental solution semigroup for operator differential Riccati equations is developed. This fundamental solution semigroup is constructed via an auxiliary finite horizon optimal control problem whose value functional growth with respect to time horizon is determined by a particular solution of the operator differential Riccati equation of interest. By exploiting semiconvexity of this value functional, and the attendant max-plus linearity and semigroup properties of the associated dynamic programming evolution operator, a semigroup of max-plus integral operators is constructed in a dual space defined via the Legendre-Fenchel transform. It is demonstrated that this semigroup of max-plus integral operators can be used to propagate all solutions of the operator differential Riccati equation that are initialized from a specified class of initial conditions. As this semigroup of max-plus integral operators can be identified with a semigroup of quadratic kernels, an explicit recipe for the aforementioned solution propagation is also rendered possible.

Optically active 2a is easily hydrolyzed to the corresponding carbinol 2b. The optical purity of 2b is determined via diastereomeric esters. Als Zwischenprodukt des Chlorameisensäureethylester-Abbaus von Laudanosin [(-)-)1] zum Stilben 3 hat Gadamer das α-Chlorbisbenzylderivat 2a formuliert. Optisch aktives 2a wird leicht zum entsprechenden Carbinol 2b hydrolysiert, dessen optische Reinheit über diastereomere Ester bestimmt wird.

description: Radical-ion pairs, fundamental for understanding photosynthesis and the avian magnetic compass, were recently shown to be biological open quantum systems. We here show that the coupling of the radical-pair's spin degrees of freedom to its decohering vibrational reservoir leads to a shift of the radical-pair's magnetic energy levels. The Lamb shift Hamiltonian is diagonal in the singlet-triplet basis, and results in a singlet-triplet energy splitting physically indistinguishable from an exchange interaction. This could have significant implications for understanding the energy level structure and the dynamics of photosynthetic reaction centers.

description: The lockdown, commencing in India from March 23, 2020 to control the escalation of Covid-19 cases, exhibited a positive impact on the air quality. The study attempts to assess the outcome of lockdown on the air quality of Kolkata, India followed by the comparison of six priority pollutants during pre-lockdown, lockdown, and unlock phases. Averaged concentrations of PM10 (72%), PM2.5 (73%), NOx (84%), SO2 (48%), and CO (61%) showed reduction throughout lockdown in comparison with pre-lockdown phase, although no significant reduction was observed in ground-level Ozone. Unlock Phases I and II showed similar concentrations of the pollutants as that in the lockdown period whereas, in unlock Phase-III, the air quality became comparable to that before lockdown. Statistical analysis confirmed that the reduction in air pollution is attributed to atmospheric factors. PCA analysis established significant positive correlation between particulate matters, CO, SO2, and NOx; however, no significant correlation was observed between NOx and O3. January and December showed the highest load of most of the pollutants. Health risk was evaluated by calculating the Relative risk and Health Air Quality Index, which showed maximum health risk during the pre-lockdown and minimum during lockdown and unlock Phase-II with the highest contributor being PM10. The study outcome manifests a reduction in environmental pollution as a result of controlled anthropogenic activities.

description: In this note we study the topology of 3-dimensional initial data sets with horizons of a sort associated with asymptotically locally anti-de Sitter spacetimes. We show that, within this class, those initial data sets which contain no (immersed) marginally outer trapped surfaces in their interior must have simple topology: they are a product of a surface and an interval, or a mild variation thereof, depending on the connectedness of the horizon and on its genus relative to that of the end. The results obtained here extend results in [11] to the case of higher genus ends.

description: Several low-dimensional systems show a crossover from diffusive to ballistic heat transport when system size is decreased. Although there is some phenomenological understanding of this crossover phenomena in the coarse grained level, a microscopic picture that consistently describes both the ballistic and the diffusive transport regimes has been lacking. In this work we derive a scaling from for the thermal current in a class of one dimensional systems attached to heat baths at boundaries, and show rigorously that the crossover occurs when the characteristic length scale of the system competes with the system size.

description: The data is used to investigate the structures of Estonian and Lithuanian Master’s theses, focusing in particular on the question of whether and to what extent these texts adhere to, or depart from, the standard IMRaD structure. By applying an automatic analysis, we ask whether elements of text structures can be detected automatically, and if so, with which types of methods. As we work both with Estonian and Lithuanian data, we also ask whether it is feasible to develop a method which would work independently of the language used.

Vortrag

description: Die Charité hat sich zum Ziel gesetzt, offene Forschungspraktiken zu inzentivieren. Eine der Maßnahmen hierfür ist die Vergabe leistungs­orientierter Mittel (LOM) für Publikationen, zu denen Forschungs­daten geteilt wurden. Diese „Open Data-LOM“, die auch zugangsbe­schränkte Daten berücksichtigt, wird seit 2019 vergeben. Um diese Mittel vergeben zu können, müssen die Artikel detektiert werden, zu denen Daten geteilt wurden. Ein erstes Screening wird mit dem von uns entwickelten Open Source Text Mining-Algorithmus ODDPub vorgenommen. Für die Vergabe leistungsorientierter Mittel muss der Open Data-Begriff jedoch darüber hinaus soweit operationali­siert werden, dass eine dichotome Ja-Nein-Entscheidung möglich wird. Hierfür haben wir einen Kriterienkatalog erarbeitet, mit dem wir für biomedizinische Publikationen eine solche Entscheidung treffen können. Der Vortrag wird diese Kriterien im Detail vorstellen und diskutieren, warum wir uns für genau diese Operationalisierung von Open Data entschieden haben. Ebenso werden auch die noch bestehenden – und vielleicht unumgänglichen – Schwierigkeiten bei der Anwendung zur Sprache komme. Technisch haben wir die Prü­fung der Kriterien im Open Source-Tool Numbat implementiert, das ursprünglich für Systematische Reviews entwickelt wurde. Der Vor­trag wird auch diese praktische Umsetzung, wie von uns als Protokoll veröffentlicht, kurz vorstellen. Abschließend werden auch die Ergeb­nisse unseres Screenings und ihre Visualisierungen in Dashboards vorgestellt. Damit wird der Vortrag einen Einblick in ein bestehendes institutionelles Screening auf Open Data geben, und kann eine Hilfestellung für andere Einrichtungen bei der Implementierung eines Open Data-Monitorings sein.

Dynamical evolution of $U(1)$ gauged Q-balls in axisymmetry

description: We study the dynamics of $U(1)$ gauged Q-balls using fully non-linear numerical evolutions in axisymmetry. Focusing on two models with logarithmic and polynomial scalar field potentials, we numerically evolve perturbed gauged Q-ball configurations in order to assess their stability and determine the fate of unstable configurations. Our simulations suggest that there exist both stable and unstable branches of solutions with respect to axisymmetric perturbations. For solutions belonging to the stable branch, the gauged Q-balls respond to the perturbations by oscillating continuously or weakly radiating before returning to the initial configuration. For the unstable branch, the solutions are eventually destroyed and can evolve in several ways, such as dispersal of the fields to infinity or fragmentation into smaller gauged Q-balls. In some cases, we observe the formation of ring-like structures which we call "gauged Q-rings". We also investigate the stability of gauged Q-balls when the gauge coupling is small, finding that the behaviour of these configurations closely resembles that of ordinary (non-gauged) Q-balls.

Reassessing the causal connection between satDNA dynamics and chromosomal evolution in Ctenomys (Rodentia, Ctenomyidae): Unveiling the overlooked importance of the Y chromosome

description: Satellite DNAs (satDNA) have long been recognized as a major driving force in karyotypic repatterning, owing to their ability to recombine between non-homologous chromosomes. A quite extensively studied model is the Repetitive PvuII Ctenomys Sequence (RPCS), the main component of constitutive heterochromatin in rodents of the genus Ctenomys (Rodentia, Ctenomyidae). At the genus level, fluctuations in RPCS copy number have been previously associated with karyotypic instability. However, when a microevolutionary approach was assayed in the most karyotypically variable lineage of the genus, the vast population-level copy number variation precluded any possibility of analyzing it in a phylogenetic framework. However, the existence of sex-related differences as a source of variability was not considered until later, when chromosomal banding suggested that the Y chromosome may be a significant reservoir of RPCS. This study aimed to investigate the bias associated with the presence of the Y chromosome in RPCS copy number variation in the Corrientes group of Ctenomys. The results revealed that the Y chromosome harbors almost twice the amount of RPCS compared to the rest of the chromosome complement, explaining the high levels of intrapopulation variation. The evolution of RPCS copy number in males and females showed independent patterns, attributable to the Y chromosome. The correlation between RPCS dynamics and diploid number fluctuations was also investigated, concluding that some karyotypic repatterning events could be explained by satDNA amplification/deletion, but not all of them. This study highlights the importance of considering differences resulting from the differential accumulation of satDNA in the heterogametic chromosome.

description: We study the effect of Coulomb interactions on the low energy band structure of single-layer transition metal dichalcogenide semiconductors using an effective low energy model. We show how a large conduction band spin splitting and a spin dependent Fermi velocity are generated in MoS$_2$, as a consequence of the difference between the gaps of the two spin projections induced by the spin-orbit interaction. The conduction band and Fermi velocity spin splittings found are in agreement with the optical absorption energies of the excitonic peaks A, B measured in the experiments.
