description: Motivated by experimental evidence for mixed-valence correlations affecting the neutralization of strontium ions on gold surfaces we set up an Anderson-Newns model for the Sr:Au system and calculate the neutralization probability $α$ as a function of temperature. We employ quantum-kinetic equations for the projectile Green functions in the finite$-U$ non-crossing approximation. Our results for $α$ agree reasonably well with the experimental data as far as the overall order of magnitude is concerned showing in particular the correlation-induced enhancement of $α$. The experimentally found non-monotonous temperature dependence, however, could not be reproduced. Instead of an initially increasing and then decreasing $α$ we find over the whole temperature range only a weak negative temperature dependence. It arises however clearly from a mixed-valence resonance in the projectile's spectral density and thus supports qualitatively the interpretation of the experimental data in terms of a mixed-valence scenario.

description: Many economic time series exhibit persistent seasonal patterns. One approach to model this phenomenon is given by models including seasonal unit roots and, if several time series are considered jointly, seasonal cointegration. For quarterly time series, e.g., unit roots may be present at frequencies =2 and , in addition to the “standard unit root” at frequency zero. Gregoir (2010) has extended the fully modified OLS estimator of Phillips and Hansen (1990) from the cointegrating regression to the seasonally cointegrating regression case. In this paper, we have a similar agenda, in that we undertake the corresponding extension for the IM-OLS estimator of Vogelsang and Wagner (2014). The benefit of the seasonal IMOLS estimator, or SIM-OLS estimator, is that it forms the basis not only for asymptotic standard inference but also allows for fixed-b inference. The paper furthermore proposes a test for seasonal cointegration at all unit root frequencies. Note here that the cointegrating spaces in general differ across frequencies and have to be estimated separately for each frequency. The theoretical analysis is complemented by a simulation study.

Consequences of bulk odd-frequency superconducting states for the classification of Cooper pairs

description: We analyze symmetries and magnetic properties of Cooper pairs appearing as subdominant pairing correlations in inhomogeneous superconductors, on the basis of the quasiclassical Green-function theory. The frequency symmetry, parity, and the type of magnetic response of such subdominant correlations are opposite to those of the dominant pairing correlations in the bulk state. Our conclusion is valid even when we generalize the theory of superconductivity to recently proposed diamagnetic odd-frequency superconductors. As a consequence, Cooper pairs are classified into eight classes in terms of their symmetries and magnetic properties. Anomalous magnetic properties of subdominant components can be probed by studying the Meissner effect.

title: Die Vereinbarkeit von Schwangerschaftsabbrüchen mit der Gleichwertigkeit aller Menschenleben
Creators: name: Bauer, Eleonore
Year: 2021

description: Diese Arbeit befasst sich mit der Frage, inwieweit der Anspruch, alle Menschenleben als prinzipiell gleichwertig anzusehen theoretisch mit der moralischen Legitimität von Schwangerschaftsabbrüchen vereinbar ist. Ausgegangen wird dabei von den Überlegungen Peter Singers, der das Dogma von der Gleichwertigkeit aller Menschenleben für veraltet, nicht ausreichend begründet und vor allem der bioethischen Diskussion nicht dienlich erachtet. Anschließend werden drei weitere Theorien vorgestellt, die Schwangerschaftsabbrüche auf eine Art und Weise rechtfertigen, die die Gleichwertigkeit aller Menschen nicht in Frage stellt. Als Ergebnis kann festgehalten werden, dass die drei Theorien von Norbert Hoerster, Judith Thomson und Cheryl Abbate diesen Spagat zwar schaffen, aber unter Zuhilfenahme gewisser einschränkender Bedingungen, wie zum Beispiel dem Zeitpunkt, ab dem die Gleichwertigkeit beginnt. Dies zeigt dennoch, dass es für Befürworter*innen von Schwangerschaftsabbrüchen keine Notwendigkeit ist, das Dogma von der Gleichwertigkeit aller Menschenleben aufzugeben, wie Singer das vorschlägt.

description: We investigate the laminar flow of two-fluid mixtures inside a simple network of inter-connected tubes. The fluid system is comprised of two miscible Newtonian fluids of different viscosity which do not mix and remain as nearly distinct phases. Downstream of a diverging network junction the two fluids do not necessarily split in equal fraction and thus heterogeneity is introduced into network. We find that in the simplest network, a single loop with one inlet and one outlet, under steady inlet conditions the flow rates and distribution of the two fluids within the network loop can undergo persistent spontaneous oscillations. We develop a simple model which highlights the basic mechanism of the instability and we demonstrate that the model can predict the region of parameter space where oscillations exist. The model predictions are in good agreement with experimental observations.

description: In der vorliegenden Arbeit wird der Frage nachgegangen, in welcher Art und Weise das differenzierte Verstehen eines Volksschülers dazu beitragen kann, adäquate Handlungsmöglichkeiten in der Schule zu erarbeiten. Der Schüler, der im Fokus der Masterarbeit steht, zeigt im Schulalltag ein Verhalten, das als pädagogisch besorgniserregend betrachtet werden kann. In der Fallanalyse werden Protokolle aus einem Work Discussion-Seminar untersucht: Im Zentrum steht ein differenziertes Verstehen von innerpsychischen Aktivitäten und Prozessen. Leitend sind ausgewählte psychoanalytische Annahmen zur bestmöglichen Regulation von Emotionen sowie Annahmen zu unbewussten Abwehraktivitäten. Basierend auf diesem Verstehen werden Überlegungen möglicher hilfreicher Handlungsperspektiven für das Einzel- und auch Gruppensetting dargestellt. Dabei bezieht sich das Einzelsetting auf die Arbeit zwischen Lehrer*in und Schüler*in. Neben konkreten Handlungen, kann die spezifische Haltung der Lehrperson ebenso dazu beitragen, den Umgang mit einem Kind, welches soziale und emotionale Probleme zeigt, förderlich zu gestalten. Die Handlungsperspektiven für das Gruppensetting beschreiben die pädagogisch angeleitete Arbeit mit der Klasse. Die Gruppe als Gemeinschaft kann Einfluss auf die soziale und emotionale Entwicklung eines Kindes nehmen.

description: MiniBooNE [1] and MINERvA [2] charge current π + production data in the Delta region are discussed. It is argued that despite the differences in neutrino flux they measure the same dynamical mechanism of pion production and should be strongly correlated. The correlation is clearly seen in the Monte Carlo simulations done with NuWro generator but is missing in the data. Both normalization and the shape of the ratio of measured differential cross sections in pion kinetic energy are different from the Monte Carlo results, in the case of normalization a discrepancy is by a factor of 1.49.

Comparative analyses

description: The study used a confirmatory factor analysis based on the UTAUT model to investigate the factors that have contributed to the growth of e-commerce in both Morocco and the United Kingdom.The strength of the relationships between the several factors is then analyzed using Hofstede’s theory. A total of one hundred persons participated in this study by filling out questionnaires. They were drawn from Morocco and United Kingdom. The survey questions were not developed to gather insights into the consumption of specific goods or services. However, they were detained solely to expose the common internet buying habits of people in both countries. Using the UTAUT model, this comprehensive study shows the study’s findings and establishes its validity in both nations. Additionally, the study offers some practical recommendations for encouraging online shopping. It also shows that UTAUT scales are valid and reliable, and it recommended more research be done to enhance the model
Evaluation of Gluconobacter spp. as biocontrol agent against Phytophthora spp.
Creators: name: Tabet Dania

Publisher: name: Zenodo
Year: 2019

description: Phytophthora spp. are highly virulent plant pathogens that are common in many plant nurseries. Chemical treatments used in the control of these pathogens have negative impacts on the environment and present health risks to non-target organisms. Regular use of chemicals in control of soil-borne pathogens may also lead in development of resistance. There is a need to find and establish more effective long-term strategies for sustainable agriculture and improvement of crop growth and health. Implementation of environmentally friendly control methods is currently encouraged in an integrated management approach that minimizes the use of chemicals in nurseries. This review therefore considers in detail the application of biocontrol agents based on endophytic bacteria, as potential biological agents for the management of Phytophthora spp. In vitro evaluations of the capacities of Gluconobacter spp. to biosynthesize secondary metabolites that suppress plant diseases will be presented, along with examination of their capacity as plant growth promoting bacteria (PGPB).

description: Certain local thermal observables are considered in well-known examples of spatially open FRW spaces: Milne, open de Sitter and anti de Sitter as well as Einstein static universes. Another value for fixing the ambiguity in defining the Wick square and, hence, the local temperature is motivated in the last example. Physical consequences of that choice are discussed for static and conformal vacua in those spaces.

description: Die Straße ist ein Medium für alltägliche Lebenspraktiken und ein Eckpfeiler für die Identitätsbildung. Moderne urbane Praktiken, die den sich verändernden Lebensstilen Rechnung tragen, bedrohen die einzigartigen Qualitäten eines Raums. Die Entwicklung von Gemeinschaftsmodellen konzentrierte sich in der Regel auf großflächige Stadträume und vernachlässigte die Bedeutung sozialräumlicher Prozesse und des immateriellen Erbes in kleineren Wohngebieten. Um diese Lücke zu schließen, untersucht diese Arbeit die Schnittstelle zwischen dem wahrgenommenen Image und dem gelebten Aspekt wertvoller Straßenelemente, die Orte von Räumen unterscheiden. Die Bedeutung einer Straße lässt sich am besten aus der Perspektive ihrer Bewohner verstehen. Um zu verstehen, wie die Wahrnehmung die Nutzung prägt, werden in dieser Studie die Erzählungen und Erinnerungen von Bewohnern einer Wohnstraße (Eckersbergsgade) in einem denkmalgeschützten Arbeiterviertel (Kartoffelraekkerne) im Herzen Kopenhagens untersucht. Diese Einträge wurden durch qualitative, halbstrukturierte Interviews und durch Beobachtung von Phänomenen auf der Ebene dieser Straße gewonnen. Die Ergebnisse zeigen eine Vielzahl von individuellen und kollektiven Erzählungen über die Straße und die mit ihr verbundenen Elemente. Darüber hinaus zeigen sie die Straße als einen Ort theatralischer menschlicher Interaktionen. Durch Wiederholung und Erinnerung wird der wesentliche Charakter der Straße ständig geformt und angefochten.
description: The street is a medium for everyday life practices and a cornerstone for identity formation. Modern urban practices that cater to changing lifestyles threaten the unique qualities of a space. Developing community models typically focused on large-scale city spaces while neglecting the significance of socio-spatial processes and intangible heritage in smaller residential areas. To cover this gap, this thesis studies the interface between the perceived image and the lived aspect of valued street elements that distinguish places from spaces. The significance of any street is best understood from the perspective of its inhabitants. Hence, to understand how perceptions shape uses, this study explores narratives and memories of dwellers in a residential street (Eckersbergsgade) within a working-class heritage neighborhood (Kartoffelrækkerne [The Potato Rows]) in the heart of Copenhagen. These entries were retrieved through qualitative semi-structured interviews and observed phenomena at the level of this street. The findings reveal a multitude of individual and collective narratives on the street and the elements associated with it. In addition, they depict the street as a site of theatrical human interactions. Through repetition and recollection, the essential character of the street is continuously shaped and contested.

description: Diese Masterarbeit beschäftigt sich mit der Frage, ob KritikerInnenbewertungen einen Einfluss auf Fine-Wine-Preise haben. Nach der Auswahl der KritikerInnen wurden jene Weine mit der Höchstpunktzahl der jeweiligen KritikerInnen zu Rate gezogen und das Sample anhand entsprechender Argumente und Kriterien reduziert und verkleinert, um Fremdeinflüsse ausschließen zu können. Ein regression discontinuity in time model wurde angewandt und sowohl statistisch als auch graphisch interpretiert und erläutert. Es zeigt sich für die Mehrheit der Weine nach dem Rating ein signifikant positiver Einfluss auf den Preis. Dies stimmt mit der bestehenden Literatur überein.
description: This thesis addresses the question of whether expert ratings have an influence on fine wine prices. For this reason, a selection of renowned critics in the wine industry has been made. Subsequently a selection of the rated wines was carried out and carefully reduced according to appropriate arguments to make data comparable. A regression discontinuity in time model was applied and interpreted visually as well as statistically. Further, a Wilcoxon test was conducted to check the results. The majority of the sampled wines shows that the rating has a significantly positive impact on the price, which is in line with previous literature.

description: We present the analysis of the gravitational microlensing event OGLE-2013-BLG-0102. The light curve of the event is characterized by a strong short-term anomaly superposed on a smoothly varying lensing curve with a moderate magnification $A_{\rm max}\sim 1.5$. It is found that the event was produced by a binary lens with a mass ratio between the components of $q = 0.13$ and the anomaly was caused by the passage of the source trajectory over a caustic located away from the barycenter of the binary. From the analysis of the effects on the light curve due to the finite size of the source and the parallactic motion of the Earth, the physical parameters of the lens system are determined. The measured masses of the lens components are $M_{1} = 0.096 \pm 0.013~M_{\odot}$ and $M_{2} = 0.012 \pm 0.002~M_{\odot}$, which correspond to near the hydrogen-burning and deuterium-burning mass limits, respectively. The distance to the lens is $3.04 \pm 0.31~{\rm kpc}$ and the projected separation between the lens components is $0.80 \pm 0.08~{\rm AU}$.

description: While ferroelectric hafnia ($\mathrm{HfO_2}$) has become a technically important material for microelectronics, the physical origin of its ferroelectricity remains poorly understood. The tetragonal $P4_2/nmc$ phase is commonly assigned as its paraelectric mother phase but has no soft mode at the Brillouin zone center. In this work, we propose that the paraelectric-ferroelectric transition in hafnia-like $Pca2_1$ ferroelectric family can be described by a $Pcca$-$Pca2_1$ transition, where the $Pcca$ mother phase will evolve into either the $Pca2_1$ ferroelectric phase or the centrosymmetric $P2_1/c$ monoclinic phase, depending on the strain conditions. The $Pcca$ phase is directly linked to both phases in the context of continuous phase transition. Hafnia is regarded as a special case of this family, in that it has accidental atomic degeneracy because all anions are oxygen. The theory is also correlated to the seven-coordination theory that explains the ferroelectricity in hafnia from a chemical perspective. In addition, the strain conditions to promote the ferroelectric phase in hafnia are discussed.

description: The realization of a future quantum Internet requires processing and storing quantum information at local nodes, and interconnecting distant nodes using free-space and fibre-optic links. Quantum memories for light are key elements of such quantum networks. However, to date, neither an atomic quantum memory for non-classical states of light operating at a wavelength compatible with standard telecom fibre infrastructure, nor a fibre-based implementation of a quantum memory has been reported. Here we demonstrate the storage and faithful recall of the state of a 1532 nm wavelength photon, entangled with a 795 nm photon, in an ensemble of cryogenically cooled erbium ions doped into a 20 meter-long silicate fibre using a photon-echo quantum memory protocol. Despite its currently limited efficiency and storage time, our broadband light-matter interface brings fibre-based quantum networks one step closer to reality. Furthermore, it facilitates novel tests of light-matter interaction and collective atomic effects in unconventional materials.

description: ‘Openness’ is one of the key concepts brought forward by postindustrial narratives questioning the modern repartition of roles between industries and customers. In these narratives, citizen participation in design and intellectual property management based on open source principles are the promise of more sustainable production models. In this context, openness in product design and development has been the object of growing interest and experimentation from academia, businesses and grassroots communities. As a result, numerous concepts emerged that attempt to grasp the essence of this phenomenon, unfortunately leading to overlapping, conflicting or speculative depictions. In this article, we share the understanding we gained throughout 6 years of research on Open Design and Open Source Hardware and attempt to make the difference between myths and facts. We depict an enthusiastic but realistic picture of Open Design and Open Source Hardware practices as we could observe them and deliver a structured framework to situate concepts and their differences. From this, we share seven observations leading to seven corresponding research questions and establish a research agenda to stimulate further investigations into this socially relevant and potentially ground-breaking phenomenon.

description: We present multi-frequency (1-8 GHz) VLA data, combined with VIMOS IFU data and HST imaging, of a z=0.085 radio-quiet type 2 quasar (with L(1.4GHz)~5e23 W/Hz and L(AGN)~2e45 erg/s). Due to the morphology of its emission-line region, the target (J1430+1339) has been referred to as the Teacup AGN in the literature. We identify "bubbles" of radio emission that are extended ~10-12 kpc to both the east and west of the nucleus. The edge of the brighter eastern bubble is co-spatial with an arc of luminous ionized gas. We also show that the Teacup AGN hosts a compact radio structure, located ~0.8 kpc from the core position, at the base of the eastern bubble. This radio structure is co-spatial with an ionized outflow with an observed velocity of v=-740 km/s. This is likely to correspond to a jet, or possibly a quasar wind, interacting with the interstellar medium at this position. The large-scale radio bubbles appear to be inflated by the central AGN, which indicates that the AGN can also interact with the gas on >~10 kpc scales. Our study highlights that even when a quasar is formally "radio-quiet" the radio emission can be extremely effective for observing the effects of AGN feedback.

title: Immersive Online-Theaterstücke als Bildungsanlass
Creators: name: Zigelli, Annika
Year: 2021

description: Bei immersivem Theater ist das Publikum konstitutiver Teil der erzählten Geschichte, taucht förmlich in das Geschehen ein und interagiert sowohl mit den Schauspieler*innen, als auch mit dem anderen Publikum. Die folgende Masterarbeit untersucht das immersive Online-Theaterstück ‚Goodbye Kreisky‘ von der Performance Gruppe ‚Nesterval‘ als möglichen Bildungsanlass für das teilnehmende Publikum und dessen weiterführende Bildungs- bzw. Lernprozesse. Dafür werden auf der medienpädagogischen Grundlage von Norbert Meders relationaler Bildungstheorie (2007, 2014, 2017) die Transkriptionen von Fokusinterviews mit sechs Menschen aus dem Publikum vor, direkt nach und eine Woche nach dem Besuch des Theaterstücks innerhalb einer qualitativen Inhaltsanalyse auf die Forschungsfragen hin analysiert. Die Ergebnisse der Forschungsarbeit zeigen, dass das immersive Online-Theaterstück ein Bildungsanlass war und vor allem durch seine spezielle immersive Form verschiedene Bildungsprozesse beim Publikum ausgelöst hat.
description: The spectators of immersive theatre are a constituent part of the story which is told. They literally are immersed in the event and interact with the actors and actresses and the other spectators. The following master thesis explores whether the immersive online theatre play ‘Goodbye Kreisky’ by the performance group ‘Nesterval’ can act as an educational occasion for the spectators and therefore, initiate potential educational or learning processes. The relational education theory of Norbert Meder (2007, 2014, 2017) serves as the theoretical basis for the empirical research and analysis. The focused interviews of six spectators right before, right after, and one week after the play were analysed with a qualitative content analysis in regard with the research questions. The results of the study show that the play has acted as an educational occasion and initiated some educational processes within the spectators due to its special immersive format.
Effect of active cargo containers on aircraft smoke transport

description: A simulated model of a full-sized aircraft cargo compartment was used to determine the effect of active cargo containers. Physical testing in conjunction with the simulated cargo compartment was used to validate the accuracy of the Fire Dynamics Simulator model which included an artificial smoke generator. The artificial smoke generator is currently used in certification of smoke detectors in aircraft cargo compartments. It consisted of heaters that vaporize oil to create smoke.Arranging cargo containers with the smoke generator gives a baseline for smoke movement in the compartment. The smoke was measured using lasers and light meters which were partially obscured by the moving smoke. Fans were added to the containers as a stand-in for temperature-controlled cargo containers (TCC), also called “active” cargo containers, that had condenser cooling fans.Comparing the experimental test data to the simulated test data showed that the simulation is a good fit. The smoke trends between the tests are very similar and there was a difference in detection time typically less than 10 seconds over the entirety of the tests.Using the Envirotainer RKN e1 as a typical TCC, an airflow of 35 CFM was used for the experimental testing. According to the testing and simulations, using TCCs with airflows of 17.5 or 35 CFM has an inconsistent effect on the smoke detection time, at the extremes, ±20 seconds, ±30% of detection time. At elevated airflow of 70 and 140 CFM, the time to smoke detection was almost always delayed, an average of 30 seconds (+50%) and at most up to 70 seconds (+110%). Delay of smoke detection could cause potentially dangerous conditions in the aircraft. Because of the delay, it is recommended to keep airflow of TCCs to below 70 CFM.

description: We present the first self-consistent global simulations of pulsar magnetospheres with operating $e^\pm$ discharge. We focus on the simple configuration of an aligned or anti-aligned rotator. The star is spun up from zero (vacuum) state to a high angular velocity, and we follow the coupled evolution of its external electromagnetic field and plasma particles using the "particle-in-cell" method. A plasma magnetosphere begins to form through the extraction of particles from the star; these particles are accelerated by the rotation-induced electric field, producing curvature radiation and igniting $e^\pm$ discharge. We follow the system evolution for several revolution periods, longer than required to reach a quasi-steady state. Our numerical experiment puts to test previous ideas for the plasma flow and gaps in the pulsar magnetosphere. We first consider rotators capable of producing pairs out to the light cylinder through photon-photon collisions. We find that their magnetospheres are similar to the previously obtained force-free solutions with a current sheet and the Y-point near the light cylinder. The magnetosphere continually ejects $e^\pm$ pairs and ions. Pair creation is sustained by a strong electric field along the current sheet. We observe powerful curvature and synchrotron emission from the current sheet, consistent with Fermi observations of gamma-ray pulsars. We then study pulsars that can only create pairs in the strong-field region near the neutron star, well inside the light cylinder. We find that both aligned and anti-aligned rotators relax to the "dead" state with suppressed pair creation and electric currents, regardless of the discharge voltage.

description: Despite enormous efforts devoted to the study of the many-body localization (MBL) phenomenon, the nature of the high-energy behavior of the Heisenberg spin chain in a strong random magnetic field is lacking consensus. Here, we take a step back by exploring the weak interaction limit starting from the Anderson localized (AL) insulator. Through shift-invert diagonalization, we find that below a certain disorder threshold $h^*$, weak interactions necessarily lead to ergodic instability, whereas at strong disorder the AL insulator directly turns into MBL. This agrees with a simple interpretation of the avalanche theory for restoration of ergodicity. We further map the phase diagram for the generic XXZ model in the disorder $h$ -- interaction $Δ$ plane. Taking advantage of the total magnetization conservation, our results unveil the remarkable behavior of the spin-spin correlation functions: in the regime indicated as MBL by standard observables, their exponential decay undergoes a unique inversion of orientation $ξ_z>ξ_x$. We find that the longitudinal length $ξ_z$ is a key quantity for capturing ergodic instabilities, as it increases with system size near the thermal phase, in sharp contrast to its transverse counterpart $ξ_x$.

description: The SDC_GLO_CLIM_TS_V2 product is an improved version of SDC_GLO_CLIM_TS_V1 and contains two different monthly climatologies for temperature and salinity from the World Ocean Database 2018 (WOD-18). Along with the basic quality control flags from the WOD-18, an additional quality control named Nonlinear Quality Control (NQC) is applied. The first climatology, V2_1, considers temperature and salinity profiles from Conductivity Depth Temperature (CTD), Ocean station data (OSD) and Moored buoy data (MRB) along with Profiling Floats (PFL) from 1900 to 2017. The second climatology, V2_2, utilizes only PFL data from 2003 to 2017. V2_1 considers 44 layers from surface to 6000 m while V2_2 only 34 from 0 to 2000 m. The gridded fields are computed using DIVAnd (Data Interpolating Variational Analysis) version 2.3.1. Basic statistics for differences between the WOD gridded fields, so-called World Ocean Atlas 2018 (WOA-18) and the SDC_GLO analyses are computed and the estimates are found to be consistent.

description: Stroke is primarily a neurodegenerative disease but can also severely impact the functions of other vital organs and deteriorate disease outcomes. A malfunction of the gastrointestinal tract (GIT), commonly observed in stroke patients, is often characterized by severe bowel obstruction, intestinal microbiota changes and inflammation. Over-activated immune cells after stroke are the major contributors to endorse intestinal inflammation and may induce damage to single-layer epithelial cell barriers. The post-stroke leakage of intestinal barriers may allow the translocation and dissemination of resident microflora to systemic organs and cause sepsis. This overshooting systemic immune reaction fuels ongoing inflammation in the degenerating brain and slows recovery. Currently, the therapeutic options to treat these GIT-associated anomalies are very limited and further research is required to develop novel treatments. In this mini-review, we first discuss the current knowledge from clinical studies and experimental stroke models that provide strong evidence of the existence of post-stroke GIT complications. Then, we review the literature regarding novel therapeutic approaches that might help to maintain GIT homeostasis and improve neurological outcomes in stroke patients.

description: The James Webb Space Telescope (JWST) is unveiling astounding results about the first few hundred million years of life of the Universe, delivering images of galaxies at very high redshifts. Here, we develop a UV luminosity function model for high-redshift galaxies, considering parameters such as the stellar formation rate, dust extinction, and halo mass function. Calibration of this luminosity function model using UV luminosity data at redshifts z = 4-7 yields optimal parameter values. Testing the model against data at higher redshifts reveals successful accommodation of the data at z = 8-9, but challenges emerge at z~13. Our findings suggest a negligible role of dust extinction at the highest redshifts, prompting a modification of the stellar formation rate to incorporate a larger fraction of luminous objects per massive halo, consistently with similar recent studies. This effect could be attributed to mundane explanations such as unknown evolution of standard astrophysics at high redshift or to the existence of exotic objects at high redshift. We comment on this latter possibility.

description: The equations of motion of a charged particle in the field of Yang's $\mathrm{SU}(2)$ monopole in 5-dimensional Euclidean space are derived by applying the Kaluza-Klein formalism to the principal bundle $\mathbb{R}^8\setminus\{0\}\to\mathbb{R}^5\setminus\{0\}$ obtained by radially extending the Hopf fibration $S^7\to S^4$, and solved by elementary methods. The main result is that for every particle trajectory $\mathbf{r}:I\to\mathbb{R}^5\setminus\{0\}$, there is a 4-dimensional cone with vertex at the origin on which $\mathbf{r}$ is a geodesic. We give an explicit expression of the cone for any initial conditions.
