description: We demonstrate that among all quantum teleportation protocols giving rise to the same average fidelity, those with aligned Bloch vectors between input and output states exhibit the minimum average trace distance. This defines optimal protocols. Furthermore, we show that optimal protocols can be interpreted as the perfect quantum teleportation protocol under the action of correlated one-qubit channels. In particular, we focus on the deterministic case, for which the final Bloch vector length is equal for all measurement outcomes. Within these protocols, there exists one type that corresponds to the action of uncorrelated channels: these are depolarizing channels. Thus, we established the optimal quantum teleportation protocol under a very common experimental noise.

title: Untersuchung des (post-)meritokratischen Narrativs
Creators: name: Wernig, Vanessa
Year: 2022

description: Zeitgenössische Filme der letzten Jahre zeugen von einer neuen Inszenierungstendenz, welche das Scheitern des meritokratischen Aufstiegsversprechens ins Zentrum rücken. Diese Arbeit beschäftigt sich mit eben jener neuen Inszenierungstendenz, dem postmeritokratischen Narrativ, und untersucht, wie durch die Verknüpfung von theoretischen, inszenierungsanalytischen sowie autobiographischen Methoden dieses in seinem Vorkommen konkret gefasst werden kann. Ausgehend von Lauren Berlants Theorien zum Cinema of Precarity und Andrea Seiers und Stephan Trinkaus‘ Beschreibungen zum Begriff des postmeritokratischen Narrativs, werden der österreichische Dokumentarfilm Mind the Gap (R.: Robert Schabus, Österreich 2019) sowie der deutsche Spielfilm Contra (R.: Sönke Wortmann, Deutschland 2020) als Inszenierungsbeispiele bezüglich ihrer Darstellung des Postmeritokratischen untersucht. Daran anschließend folgt die autobiographische Ausarbeitung dreier Aspekte: Verhaltensweisen, Leistungen und berufliche Wege, welche anhand subjektiver Erfahrungspraxen der Autorin Schwierigkeiten im Bezug zu meritokratischen Vorstellungen vermitteln sollen. Die Arbeit nutzt einen interdisziplinären Ansatz, in welchem soziologische Begriffe in Hinblick auf film- und medienwissenschaftliche Theoreme verknüpft werden und durch welche die Relevanz der weiteren fächerübergreifenden Forschung aufgezeigt werden soll. Das postmeritokratische Narrativ kann so in seiner Komplexität aus unterschiedlichen Perspektiven beleuchtet und in seinem Bezug zur Repräsentation prekärer Lebensverhältnisse gefasst werden.
description: Contemporary movies of recent years reveal a new staging tendency that focuses on the failure of the meritocratic promise of social mobility. This thesis concerns itself with precisely this new staging tendency, the post-meritocratic narrative and shall examine its occurrence by combining theoretical, staging-analytical and autobiographical methods. Based on Lauren Berlant’s theories on the Cinema of Precarity and Andrea Seier und Stephan Trinkaus’ descriptions of the post-meritocratic narrative, the Austrian documentary Mind the Gap (R.: Robert Schabus, Österreich 2019) and the German motion picture Contra (R.: Sönke Wort-mann, Deutschland 2020) shall be analyzed as staging examples regarding their use of the post-meritocratic narrative. Thereafter, an autobiographical elaboration of three aspects is provided: behavior, achievement and professional outlook, which are used to convey difficulties pertaining to meritocratic notions on the basis of the author’s own lived experiences. This thesis demonstrates an interdisciplinary approach, in which sociological concepts are combined with theorems from film and media studies to illustrate the importance of further research spanning different subjects. This opens up the possibility of shedding light on the complexity of the post-meritocratic narrative from different perspectives and of grasping it in its relation to the representation of precarious living conditions.

description: The aim of this paper is to derive new representations for the Hankel functions, the Bessel functions and their derivatives, exploiting the reformulation of the method of steepest descents by M. V. Berry and C. J. Howls (Berry and Howls, Proc. R. Soc. Lond. A 434 (1991) 657--675). Using these representations, we obtain a number of properties of the asymptotic expansions of the Hankel and Bessel functions and their derivatives of nearly equal order and argument, including explicit and numerically computable error bounds, asymptotics for the late coefficients, exponentially improved asymptotic expansions, and the smooth transition of the Stokes discontinuities.

Analysis Optimisation with Differentiable Programming
Creators: name: Simpson, Nathan Daniel
Publisher: name: Zenodo
Year: 2022

description: This tutorial will cover how to optimise various aspects of analyses -- such as cuts, binning, and learned observables like neural networks -- using gradient-based optimisation. This has been made possible due to work on the relaxed software package, which offers a set of standard HEP operations that have been made differentiable. In addition to targeting Asimov significance, we will also use the full analysis significance that incorporates systematic uncertainties as an optimisation objective. Finally, we will reproduce the neos method for learning systematic-aware observables, and you'll see how you can modify it for your use-case.

description: Paraffin coatings on glass slides were investigated through both X-ray photoelectron spectroscopy (XPS) and spin relaxation measurement for cesium (Cs) vapor. The components of the glass substrate, such as silicon (Si) and oxygen (O), existed in the XPS spectra of the coated slides, indicating the imperfection of the prepared paraffin coatings. The substrate was not observed after the annealing of the coatings in Cs vapor, which is known as a `ripening' process for spin relaxation measurement. We found a general trend that effective anti-spin relaxation performance requires high paraffin and low Cs coverage on the surface. We also examined a type of diamond-like carbon (DLC) film, anticipating the effect of anti-spin relaxation; our attempts have failed to date.

description: The feature interaction problem occurs when two or more independently developed components interact with each other in unanticipated ways, resulting in undesirable system behaviors. Feature interaction problems remain a challenge for emerging domains in cyber-physical systems (CPS), such as the Internet of Things and autonomous drones. Existing techniques for resolving feature interactions take a "winner-takes-all" approach, where one out of the conflicting features is selected as the most desirable one, and the rest are disabled. However, when multiple of the conflicting features fulfill important system requirements, being forced to select one of them can result in an undesirable system outcome. In this paper, we propose a new resolution approach that allows all of the conflicting features to continue to partially fulfill their requirements during the resolution process. In particular, our approach leverages the idea of adaptive requirement weakening, which involves one or more features temporarily weakening their level of performance in order to co-exist with the other features in a consistent manner. Given feature requirements specified in Signal Temporal Logic (STL), we propose an automated method and a runtime architecture for automatically weakening the requirements to resolve a conflict. We demonstrate our approach through case studies on feature interactions in autonomous drones.

Developing implicitly-parallel Python analysis tools for NOvA
Creators: name: Doyle, Derek
Publisher: name: Zenodo
Year: 2022

description: The NOvA collaboration together with a Dept. of Energy ASCR supported SciDAC-4 project, have been exploring Python-based analysis workflows for HPC platforms. This research has been focused on adapting machine-learning application workflows using highly-parallel computing environments for neutrino-nucleon cross section measurements. This work accelerates scientific analysis and lowers the learning barriers required to leverage leadership computing platforms. Users of these HPC workflows have often been required to have significant experience with parallel computing libraries and principles in addition to dedicated access to accounts and resource allocations at off-site HPC/Supercomputing centers such as NERSC and the Argonne Leadership Computing Facility. With the commissioning of the new Fermilab analysis cluster, which will provide dynamically provisioned pools of HPC resources, we are now exploring ways to improve the efficiency and approachability of Python-based analysis tools. These include data organizations using HDF5 and the PandAna analysis framework, both of which natively support highly data-parallel operations. Our research enables fully data-parallel exploration, selection, and aggregation of neutrino data, which are the fundamental operations required for neutrino cross section analysis work in NOvA. These operations are executed with the analysis cluster through Jupyter notebook interfaces and have been demonstrated to achieve low execution latencies, which are highly compatible with interactive analysis time-scale(s). We have developed a method for constructing large monolithic HDF5 based files, which each represent an entire NOvA dataset, and we have demonstrated a factor of more than 10× speedup of basic event selection using this data representation, relative to equivalent multi-file composite representations of the datasets. We have developed a complete, implicitly-parallel analysis workflow with basic histogram operations and demonstrated its scalability using a realistic neutrino cross section measurement on the Perlmutter system at NERSC. These tools will enable real-time turnaround of more physics results for the NOvA collaboration and wider HEP community.

description: We present the first spectroscopic confirmation of an ultra-massive galaxy at redshift z>3 using data from Keck-NIRSPEC, VLT-Xshooter, and GTC-Osiris. We detect strong [OIII] and Ly$α$ emission, and weak [OII], CIV, and HeII, placing C1-23152 at a spectroscopic redshift of $z_{spec}$=3.351. The modeling of the emission-line corrected spectral energy distribution results in a best-fit stellar mass of $M_{*}=3.1^{+0.6}_{-0.7}\times10^{11} M_{\odot}$, a star-formation rate of <7 $M_{\odot} yr^{-1}$, and negligible dust extinction. The stars appear to have formed in a short intense burst ~300-500 Myr prior to the observation epoch, setting the formation redshift of this galaxy at z~4.1. From the analysis of the line ratios and widths, and the observed flux at 24$μ$m, we confirm the presence of a luminous hidden active galactic nucleus (AGN), with bolometric luminosity of ~$10^{46}erg s^{-1}$. Potential contamination to the observed SED from the AGN continuum is constrained, placing a lower limit on the stellar mass of $2\times10^{11} M_{\odot}$. HST/WFC3 $H_{160}$ and ACS $I_{814}$ images are modeled, resulting in an effective radius of $r_{e}$~1 kpc in the $H_{160}$ band and a Sersic index n~4.4. This object may be a prototype of the progenitors of local most massive elliptical galaxies in the first 2 Gyr of cosmic history, having formed most of its stars at z>4 in a highly dissipative, intense, and short burst of star formation. C1-23152 is completing its transition to a post-starburst phase while hosting a powerful AGN, potentially responsible for the quenching of the star formation activity.

description: This paper proposes two nonlinear dynamics to solve constrained distributed optimization problem for resource allocation over a multi-agent network. In this setup, coupling constraint refers to resource-demand balance which is preserved at all-times. The proposed solutions can address various model nonlinearities, for example, due to quantization and/or saturation. Further, it allows to reach faster convergence or to robustify the solution against impulsive noise or uncertainties. We prove convergence over weakly connected networks using convex analysis and Lyapunov theory. Our findings show that convergence can be reached for general sign-preserving odd nonlinearity. We further propose delay-tolerant mechanisms to handle general bounded heterogeneous time-varying delays over the communication network of agents while preserving all-time feasibility. This work finds application in CPU scheduling and coverage control among others. This paper advances the state-of-the-art by addressing (i) possible nonlinearity on the agents/links, meanwhile handling (ii) resource-demand feasibility at all times, (iii) uniform-connectivity instead of all-time connectivity, and (iv) possible heterogeneous and time-varying delays. To our best knowledge, no existing work addresses contributions (i)-(iv) altogether. Simulations and comparative analysis are provided to corroborate our contributions.
Scaling of Fluctuations in a Trapped Binary Condensate

description: We demonstrate that measurements of number fluctuations within finite cells provide a direct means to study fluctuation scaling in a trapped two-component condensate. This quantum system supports a second-order phase transition between miscible (co-spatial) and immiscible (symmetry-broken) states that is driven by a diverging susceptibility to magnetic fluctuations. As the transition is approached from the miscible side the magnetic susceptibility is found to depend strongly on the geometry and orientation of the observation cell. However, a scaling exponent consistent with that for the homogenous gas ($γ= 1$) can be recovered, for all cells considered, as long as the fit excludes the region in the immediate vicinity of the critical point. As the transition is approached from the immiscible side, the magnetic fluctuations exhibit a non-trivial scaling exponent $γ\simeq 1.30$. Experimentally, the observation cells may be formed either by considering individual imaging pixels or by combining pixels to form larger cells, and fluctuation statistics can be obtained by repeated \emph{in situ} images. Interestingly, on both sides of the transition, we find it best to extract the exponents using an observation cell that covers half of the trapped system. This implies that relatively low-resolution \emph{in situ} imaging will be adequate for the investigation of these exponents. We also investigate the gap energy and find exponents $νz$ = 0.505 on the miscible side and, unexpectedly, $νz$ = 0.60(3) for the immiscible phase.

description: Die Entdeckung eines neuen Hauptplaneten in unserem Sonnensystem stellte die Astronomen des 18. Jahrhunderts vor die Herausforderung, dem Himmelsobjekt einen Namen zu geben. Fast jeder wichtige Astronom Europas machte einen eigenen Namenvorschlag, verwendete diesen und der Planet hatte fast 70 Jahre lang keinen offiziellen, einheitlichen Namen. Maximilian Hell, der Direktor der Universitätssternwarte und kaiserlich-königliche Hofastronom in Wien, dichtete für seinen Namenvorschlag Urania ein Gedicht, das mit astronomischen und mythologischen Anspielungen gespickt war und brachte es in seinen jährlich herausgegebenen astronomischen Tabellen zur Verbreitung. Diese Arbeit bettet das Gedicht in den historischen Kontext der Entdeckung des Planeten und der Geschichte der Namensfindung ein. Im Hauptteil werden die astronomischen Bestandteile des Gedichtes kommentiert und der Zusammenhang mit dem Streit um die Benennung herausgestrichen. Den Abschluss bildet eine Zusammenfassung, wie der endgültige, heutige Namen des Planeten Uranus gefunden wurde und eine Begründung, wieso es heutzutage nicht mehr zu solchen Querelen unter den Astronominnen und Astronomen kommen kann.

description: We derive the null energy condition, understood as a constraint on the Einstein-frame Ricci tensor, from worldsheet string theory. For a closed bosonic string propagating in a curved geometry, the spacetime interpretation of the Virasoro constraint condition is precisely the null energy condition, to leading nontrivial order in the alpha-prime expansion. Thus the deepest origin of the null energy condition lies in worldsheet diffeomorphism invariance.

title: Die Karwoche am Wiener Hof von Karl VI. bis Joseph II.
Creators: name: Aigmüller, Rudolf
Year: 2022

description: In dieser Arbeit wird die Karwoche am Wiener Hof im 18. Jahrhundert untersucht. Für die kaiserliche Familie und die Hofgesellschaft war diese Woche bis ca. 1765 eine Zeit der Öffnung. In zahlreichen Prozessionen präsentierte sich der Hof in der Stadt. Gleichzeitig war es eine Zeit, die mit klar strukturiertem weltlichen und kirchlichen Zeremoniell verbunden war. Die Hofgesellschaft besuchte mehrmals täglich den Gottesdienst. In dieser Arbeit wird auch auf die Veränderung der Karwoche im 18. Jahrhundert eingegangen. Diese rührt aus einer, von der französischen Aufklärung beeinflussten, gesellschaftlichen Veränderung in der zweiten Hälfte des Jahrhunderts. Bräuche, die auf Volksfrömmigkeit zurückzuführen waren, wurden Großteiles abgesetzt – was am Wiener Hof blieb, waren die Gottesdienste, die auf das Konzil von Trient zurückzuführen waren. Den Hauptteil dieser Arbeit bildet die Erläuterung der einzelnen Tage von Palm- bis Ostersonntag. Dabei wurden zahlreiche Quellen miteinbezogen, um die Gottesdienste und deren Musik zu rekonstruieren. Aus der Analyse des musikalischen Charakters der Karwoche entstand eine ausführlich Tabelle mit aufgeführten Musikalien, die der Arbeit angehängt ist.
description: This work examines Holy Week at the Viennese Court in the 18th century. For the imperial family and court society, this week was a time of opening until around 1765. The Court presented itself in the city in numerous processions. At the same time, it was a time associated with clearly structured secular and ecclesiastical ceremonial. The court society attended church services several times a day. This work also deals with the change in Holy Week in the 18th century. This stems from a social change in the second half of the century influenced by the French Enlightenment. Customs based on popular piety were largely discontinued - what remained at the Viennese Court were the services based on the Council of Trent. The main part of this work is the explanation of the individual days from Palm Sunday to Easter Sunday. Numerous sources were used to reconstruct the services and their music. The analysis of the musical character of Holy Week resulted in a detailed table with listed musical works, which is appended to the work.

description: We describe why Ising spin chains with competing interactions in $\rm SrHo_2O_4$ segregate into ordered and disordered ensembles at low temperatures ($T$). Using elastic neutron scattering, magnetization, and specific heat measurements, the two distinct spin chains are inferred to have Néel ($\uparrow\downarrow\uparrow\downarrow$) and double-Néel ($\uparrow\uparrow\downarrow\downarrow$) ground states respectively. Below $T_\mathrm{N}=0.68(2)$~K, the Néel chains develop three dimensional (3D) long range order (LRO), which arrests further thermal equilibration of the double-Néel chains so they remain in a disordered incommensurate state for $T$ below $T_\mathrm{S}= 0.52(2)$~K. $\rm SrHo_2O_4$ distills an important feature of incommensurate low dimensional magnetism: kinetically trapped topological defects in a quasi$-d-$dimensional spin system can preclude order in $d+1$ dimensions.

description: The relevant length scales for superconductivity are of the order of nanometers. By confining the superconducting condensate to such dimensions, many physical properties change substantially, and novel phenomena emerge, which are absent in the pristine material. We discuss various methods of creating artificial nanostructures by top-down approaches in metallic and copper-oxide superconductors and their applications. Such nanostructures can be used to control magnetic flux quanta in superconductors, anchoring them to engineered defects to avoid dissipation, guiding their motion, or building artificial flux-quanta arrangements. Nanopatterned superconductors are essential for creating model systems for basic research and enable building almost dissipationless and ultrafast electronic devices and highly sensitive sensors.

description: Die vorliegende Masterarbeit beschäftigt sich mit Variation und Wandel von Lokal- und Direktionaladverbien in den Basisdialekten Salzburgs. Im Rahmen einer apparent-time-Studie wurden Daten von 44 Gewährspersonen, die drei verschiedenen Altersgruppen (Altersgruppe A: 18–30 Jahre, Altersgruppe B: 31–60 Jahre, Altersgruppe C: 61+ Jahre) angehören, an acht Orten im Bundesland Salzburg mittels indirekter Befragung erhoben. Der Untersuchungsgegenstand wurde in vier Phänomene untergliedert: 1) Lokaladverbien im allgemeinen Verwendungskontext, 2) Direktionaladverbien im allgemeinen Verwendungskontext, 3) Lokaladverbien mit Befindlichkeit [Ort] und 4) Direktionaladverbien mit Zielrichtung [Ort]. Die Ergebnisse zeigen, dass die Wahl verschiedener Varianten von Lokal- und Direktionaladverbien vor allem von kognitiven und innersprachlichen, z.T. aber auch von sprachgeographischen und soziolinguistischen Faktoren gesteuert wird. Bei Lokal- und Direktionaladverbien im allgemeinen Verwendungskontext hat sich insbesondere die Perspektivierung als variationsbeeinflussender kognitiver Faktor erwiesen, insofern nicht nur die Sprecherperspektive, sondern auch die Hörerperspektive oder eine neutrale Perspektive eingesetzt wird. Für Lokal- und Direktionaladverbien mit Befindlichkeit/Zielrichtung [Ort] spielt der kognitive Faktor „Orts(un)vertrautheit“ eine bedeutende Rolle. Hinsichtlich innersprachlicher Faktoren ist bei allen Untersuchungsphänomenen der Unterschied in der Verwendungsobligatorik (fakultativ vs. obligatorisch) bei Artikulation vs. Nicht-Artikulation des Verweisraums im Hinblick auf den Einsatz von oder den Verzicht auf Lokal- und Direktionaladverbien eine relevante Variable. Unter den soziolinguistischen Faktoren hat sich das Alter der Gewährspersonen nur bei Lokal- und Direktionaladverbien mit Befindlichkeit/Zielrichtung [Ort] als Einflussfaktor erwiesen. Sprachgeographische Unterschiede konnten nur zwischen der westmittelbairischen Dialektregion und den beiden anderen Dialektregionen nachgewiesen werden.

description: Assessing the condition and visibility of veins is a crucial step before obtaining intravenous access in the antecubital fossa, which is a common procedure to draw blood or administer intravenous therapies (IV therapies). Even though medical practitioners are highly skilled at intravenous cannulation, they usually struggle to perform the procedure in patients with low visible veins due to fluid retention, age, overweight, dark skin tone, or diabetes. Recently, several investigations proposed combining Near Infrared (NIR) imaging and deep learning (DL) techniques for forearm vein segmentation. Although they have demonstrated compelling results, their use has been rather limited owing to the portability and precision requirements to perform venipuncture. In this paper, we aim to contribute to bridging this gap using three strategies. First, we introduce a new NIR-based forearm vein segmentation dataset of 2,016 labelled images collected from 1,008 subjects with low visible veins. Second, we propose a modified U-Net architecture that locates veins specifically in the antecubital fossa region of the examined patient. Finally, a compressed version of the proposed architecture was deployed inside a bespoke, portable vein finder device after testing four common embedded microcomputers and four common quantization modalities. Experimental results showed that the model compressed with Dynamic Range Quantization and deployed on a Raspberry Pi 4B card produced the best execution time and precision balance, with 5.14 FPS and 0.957 of latency and Intersection over Union (IoU), respectively. These results show promising performance inside a resource-restricted low-cost device.

description: Designing digital artifacts is not a linear, straightforward process. This is particularly true when applying a user-centered design approach, or co-design, with users who are unable to participate in the design process. Although the reduced participation of a particular user group may harm the end result, the literature on solving this issue is sparse. In this article, proxy design is outlined as a method for involving a user group as proxy users to speak on behalf of a group that is difficult to reach. We present a design ethnography spanning three years at a cancer rehabilitation clinic, where digital artifacts were designed to be used collaboratively by nurses and patients. The empirical data were analyzed using content analysis and consisted of 20 observation days at the clinic, six proxy design workshops, 21 telephone consultations between patients and nurses, and log data from the digital artifact. We show that simulated consultations, with nurses roleplaying as proxies for patients ignited and initiated the design process and enabled an efficient in-depth understanding of patients. Moreover, we reveal how proxy design as a method further expanded the design. We illustrate: (1) proxy design as a method for initiating design, (2) proxy design as an embedded element in co-design and (3) six design guidelines that should be considered when engaging in proxy design. The main contribution is the conceptualization of proxy design as a method that can ignite and initiate the co-design process when important users are unreachable, vulnerable or unable to represent themselves in the co-design process. Based on the empirical findings from a design ethnography that involved nurses as proxy users speaking on behalf of patients, the article shows that roleplaying in proxy design is a fitting way of initiating the design process, outlining proxy design as an embedded element of co-design.

description: We describe a universal scheme of quantum computation by state injection on rebits (states with real density matrices). For this scheme, we establish contextuality and Wigner function negativity as computational resources, extending results of [M. Howard et al., Nature 510, 351--355 (2014)] to two-level systems. For this purpose, we define a Wigner function suited to systems of $n$ rebits, and prove a corresponding discrete Hudson's theorem. We introduce contextuality witnesses for rebit states, and discuss the compatibility of our result with state-independent contextuality.

description: Software testing is an inevitable part of software development to ensure the quality of the product. Thorough testing of software, however, might consume an significant amount of time and resources. Therefore, already decades ago, research has begun to reduce this effort by automating the process, while improving the efficiency of testing as well. One of the recommended methods is white-box test generation, which uses only the source code to generate test cases. Although there are several types of techniques using this idea - including symbolic execution, search-based testing, and guided random testing - the complexity of real-world software can make their application burdensome. These techniques usually suffer from issues, when the software under test interacts with its environment, structured objects should be created for good coverage, valid test oracles should be guessed, or the size of the program is too large. Furthermore, the use of such advanced techniques is not trivial for ordinary developers or testers due to their underlying complexity, hence the identification of test generation problems can be a difficult task as well. This work empirically evaluates these challenges and addresses some of them by proposing new techniques and tools for white-box test generation.

description: We test the hypothesis that (3) Juno is a parent body of the H chondrites with dynamical modeling of an asteroid-family-forming impact and comparison to current observational data. Using a dynamical model that includes the Yarkovsky force on a simulated Juno family and a simplified cosmic ray exposure age model we examine the expected distribution of Juno family members in both the main belt and near-Earth orbits over 300 Myrs and the cosmic ray exposure distribution for fragments exiting the main belt via the 3:1J, 5:2J, and 8:3J mean motion resonances. We find that the smallest modeled ($D<$10 m) family members of (3) Juno cannot be directly responsible for the observed H chondrite flux and that the breakup of larger family members creates an CRE distribution that resembles the measured H chondrite CRE distribution but is still unable to adequately explain the significant number of H chondrites with CRE ages of 6-8 Myrs. A similar model was performed for the asteroid (6) Hebe, another parent body candidate, and produced a CRE age distribution that is inconsistent with the measured H chondrite CRE ages. We also find from our dynamical models that we can expect $<$7 km-scale Juno family members in near-Earth orbits in the present day, consistent with the recent discovery of the shock-darkened H chondrite-like asteroid (52768) 1998 OR$_{2}$.

description: The Outer-Edge Veto (OEV) counter subsystem for extra-photon detection from the backgrounds for the? $K^0_L\rightarrowπ^0ν\barν$ decay is located at the outer edge of the endcap CsI calorimeter of the KOTO experiment at J-PARC. The subsystem is composed of 44 counters with different cross-sectional shapes. All counters are made of lead and scintillator plates and read out through wavelength-shifting fibers. In this paper, we discuss the design and performances of the OEV counters under heavy load ($\sim8$ tons/m$^2$) in vacuum. For 1-MeV energy deposit, the average light yield and time resolution are 20.9 photo-electrons and 1.5 ns, respectively. Although no pronounced peak by minimum-ionizing particles is observed in the energy distributions, an energy calibration method with cosmic rays works well in monitoring the gain stability with an accuracy of a few percent.

title: Interpreting for the Colombian indigenous communities
Creators: name: Gonzalez Figueroa, Laura Andrea
Year: 2022

description: In der vorliegenden Arbeit wird die Sprachen- und Translationspolitik Kolumbiens analysiert und ein Vergleich zu den Einstellungen und Wahrnehmungen der kolumbianischen indigenen Gemeinschaft der Misak gezogen. Dafür wurden mit Angehörigen der Gemeinschaft qualitative Interviews geführt. Um das nötige Hintergrundwissen für die Analyse zu schaffen, wird zu Beginn die Sprachenpolitik im Allgemeinen näher untersucht. Danach folgt ein Überblick über wichtige linguistische und zeitgeschichtliche Aspekte indigener Gemeinschaften Lateinamerikas. Ein weiterer Fokus liegt auf wichtige historische Ereignisse der jüngeren Geschichte Kolumbiens und deren Auswirkungen auf die indigenen Gemeinschaften im Land. Die Analyse zeigt, dass Gesetze und Politiken zum Schutz von indigenen Sprachen in Kolumbien nur unzureichend umgesetzt werden. Wenn die Regierung und die indigenen Gemeinschaften sich nur unzureichend beteiligen, werden die am Papier schon fortschrittlichen Schutzmaßnahmen schwer erfolgreich sein.
description: This paper examines the language and translation policy in Colombia and contrasts its findings with qualitative interviews conducted with members of the Misak Indigenous community in the country, to enquire about their perspective regarding existing policies and their implemen- tation. To provide the necessary background for this analysis, this paper explores three main topics: first, language policy in a general sense; second, an overview of Indigenous peoples and their languages; third, Colombia’s particular historical and social context and its effects on the Indigenous communities in the country. The analysis of the interviews suggest that even if there are policies protecting and promoting Indigenous languages in Colombia, the policies will hardly materialize unless the government and the communities make an effort and actively work towards making them a reality.

description: The BPS Skyrme model has been demonstrated already to provide a physically intriguing and quantitatively reliable description of nuclear matter. Indeed, the model has both the symmetries and the energy-momentum tensor of a perfect fluid, and thus represents a field theoretic realization of the "liquid droplet" model of nuclear matter. In addition, the classical soliton solutions together with some obvious corrections (spin-isospin quantization, Coulomb energy, proton-neutron mass difference) provide an accurate modeling of nuclear binding energies for heavier nuclei. These results lead to the rather natural proposal to try to describe also neutron stars by the BPS Skyrme model coupled to gravity. We find that the resulting self-gravitating BPS Skyrmions provide excellent results as well as some new perspectives for the description of bulk properties of neutron stars when the parameter values of the model are extracted from nuclear physics. Specifically, the maximum possible mass of a neutron star before black-hole formation sets in is a few solar masses, the precise value depending on the precise values of the model parameters, and the resulting neutron star radius is of the order of 10 km.

The impact of nostalgia on college belonging and college optimism among first-generation college students

description: • First generation (students whose parents did not earn a college degree) often come to college feeling uncertain about whether they fit or belong in college• Belonging concerns are linked to pessimistic attitudes about success; when first-gen students face academic struggles they are likely to view these struggles as evidence that they do not belong• Different psychological interventions and foundational initiatives (i.e, TRiO and summer bridge programs) have been implemented to promote adaptive mindsets for their belonging concerns.• We hypothesize that nostalgia has the capacity to promote sense of belonging and academic optimism among first-generation college students.• Nostalgic reflection inspires the confidence needed to connect with others• Nostalgia inspires optimism about future success

description: We demonstrate that the inclusion of a realistic lepton sector can relax significantly the upper bound on top partner masses in minimal composite Higgs models, induced by the lightness of the Higgs boson. To that extend, we present a comprehensive survey of the impact of different realizations of the fermion sectors on the Higgs potential, with a special emphasis on the role of the leptons. The non-negligible compositeness of the $τ_R$ in a general class of models that address the flavor structure of the lepton sector and the smallness of the corresponding FCNCs, can have a significant effect on the potential. We find that, with the $τ_R$ in the symmetric representation of $SO(5)$, an increase in the maximally allowed mass of the lightest top partner of $\gtrsim 1$ TeV is possible for minimal quark setups like the MCHM$_{5,10}$, without increasing the tuning. A light Higgs boson $m_H \sim(100-200)$ GeV is a natural prediction of such models, which thus provide a new setup that can evade ultra-light top partners without ad-hoc tuning in the Higgs mass. Moreover, we advocate a more minimal realization of the lepton sector than generally used in the literature, which still can avoid light partners due to its contributions to the Higgs mass in a different and very natural way, triggered by the seesaw mechanism. This allows to construct the most economical $SO(5)/SO(4)$ composite Higgs models possible. Using both a transparent 4D approach, as well as presenting numerical results in the 5D holographic description, we demonstrate that, including leptons, minimality and naturalness do not imply light partners. Leptonic effects, not considered before, could hence be crucial for the viability of composite models.

Publisher: name: Zenodo
Year: 2024

description: This thesis is aimed at studying the psycho-pedagogical aspects of using the spiritual heritage of the ancients. In its time, the Jadidlar movement promoted renewal in education and upbringing and developed spiritual and moral values with its pedagogical approaches. The article analyzes the psycho-pedagogical aspects of modern educational methods and spiritual education approaches. Their methods of meeting psychological needs and taking into account the individual characteristics of students, as well as their role in spiritual development, are considered. It will be discussed how the use of the spiritual heritage of the ancients can help in the development of psycho-pedagogical approaches in the modern education system and have a positive effect on the spiritual and moral development of students.
