description: We analyze the spin dynamics of an individual magnetic atom (Mn) inserted in a II-VI semiconductor quantum dot under resonant optical excitation. In addition to standard optical pumping expected for a resonant excitation, we show that for particular conditions of laser detuning and excitation intensity, the spin population can be trapped in the state which is resonantly excited. This effect is modeled considering the coherent spin dynamics of the coupled electronic and nuclear spin of the Mn atom optically dressed by a resonant laser field. This spin population trapping mechanism is controlled by the combined effect of the coupling with the laser field and the coherent interaction between the different Mn spin states induced by an anisotropy of the strain in the plane of the quantum dot.

description: The introduction of General Data Protection Regulation (GDPR) means that organisations are responsible for data protection for all individuals within the E.U. One area of operation that is unclear is to what degree aerial camera systems capture personal data. Mega-pixels and ground sampling distance are normally used as metrics for camera resolution but they ignore a multitude of factors and do not re ect the actual resolving power of the camera system. This work examines the resolution gap by detailing what is actually captured in the image output and how this can be used as an objective measure when addressing privacy concerns. A methodology is described for easily benchmarking the output for dierent camera systems at dierent heights and then two of the most commonly used capture systems on modern drones are evaluated. Finally, we examine how this can be applied to GDPR policy and how aerial surveys can be constructed that remove any personal data from the dataset.
Late Stages of Stellar Evolution - Herschel's contributions

description: Cool objects glow in the infrared. The gas and solid-state species that escape the stellar gravitational attraction of evolved late-type stars in the form of a stellar wind are cool, with temperatures typically $\la$1500\,K, and can be ideally studied in the infrared. These stellar winds create huge extended circumstellar envelopes with extents approaching $10^{19}$\,cm. In these envelopes, a complex kinematical, thermodynamical and chemical interplay determines the global and local structural parameters. Unraveling the wind acceleration mechanisms and deriving the complicated structure of the envelopes is important to understand the late stages of evolution of ~97% of stars in galaxies as our own Milky Way. That way, we can also assess the significant chemical enrichment of the interstellar medium by the mass loss of these evolved stars. The Herschel Space Observatory is uniquely placed to study evolved stars thanks to the excellent capabilities of the three infrared and sub-millimeter instruments on board: PACS, SPIRE and HIFI. In this review, I give an overview of a few important results obtained during the first two years of Herschel observations in the field of evolved low and intermediate mass stars, and I will show how the Herschel observations can solve some historical questions on these late stages of stellar evolution, but also add some new ones.

description: Many of the current approaches to automatic organ localisation in medical imaging require a large amount of labelled patient data to train systems to accurately identify specific anatomical features. Cross- Correlation, also known as template matching, is a statistical method of assessing the similarity between a template image and a target image. This method has been modified and presented here to localize the liver in Computed Tomography volume images in the Coronal and Sagital planes to achieve a mean positioning error of approximately 11 mm and 20 mm respectively based on between 1 and 25 datasets to create the template liver.

description: High precision comparisons of the proton and antiproton g-factor enable stringent tests of CPT symmetry in the baryonic sector. However, current measurement routines suffer from long preparation times and high particle temperatures, which complicate the increase of the precision beyond the parts per billion regime. As a solution, new sympathetic cooling schemes based on co-trapped laser-cooled ions may be used to cool (anti-)protons to the ground state of motion and to significantly decrease particle preparation times. In addition, motional coupling to an auxiliary ion in a double-well potential can be used for the implementation of new readout schemes based on quantum logic spectroscopy for the spin-state of the (anti-)protons. This thesis describes a cryogenic Penning trap system for ground state cooling of single 9Be+ ions, which represents the latest development of the BASE experiment in Hannover towards the implementation of sympathetic cooling schemes and quantum logic spectroscopy of single (anti-)protons. Furthermore, the setup and implementation of lasers systems at 313nm for Doppler cooling, repumping and Raman interactions are described. To this end, an optical platform for laser beam delivery to the vacuum system and an optical phase-locked loop for the stabilization of the relative phase of two lasers at 313 nm are presented. In this work, the laser systems are used for measurements of the optical resonance frequencies for cooling, probing and repumping of 9Be+ ions. In addition, stimulated Raman transitions are demonstrated using two phase-locked lasers at 313nm. In the following, this technique is used for high-precision measurements of the qubit frequency and the magnetic field, as well as themometry measurements with 9Be+ ions. The temperature of the ions after Doppler cooling is measured as a function of the cooling laser parameters and a minimal axial mode temperature of 1.77(10) mK is obtained. The results of this thesis pave the way for sideband spectroscopy and ground state cooling of single 9Be+ ions in Penning traps, which is an essential prerequisite for sympathetic ground state cooling of single (anti-)protons and the application of quantum logic spectroscopy to (anti-)proton g-factor measurements in the future.

description: The aim of this work is twofold: (i) to properly define a wave-generation formalism for compact-supported sources embedded in Einstein-Maxwell theory, relying on matched post-Newtonian and multipolar-post-Minkowskian expansions; (ii) to apply this formalism (which is valid for any type of post-Newtonian sources) to the case of two stars with constant and aligned magnetic dipoles, by computing the fluxes of energy and angular momentum to the next-to-leading order, as well as the gravitational amplitude modes. Assuming eccentric orbits, we derive the evolution of orbital parameters, as well as the observables of the system, notably the gravitational phase for quasi-circular orbits. Finally, we give some numerical estimates for the contribution of the magnetic dipoles for some realistic systems.
title: Counting Platelets: a Novel Image Analysis Algorithm for Detecting and Counting Platelet Adhesion on an Assay Pattern
titleType: Other

description: Changes in platelet function is a major complication in patients with cardiovascular disease. The authors have previously designed a portable, easy to use, low cost biochip for monitoring of anti-platelet therapy in cardiovascular disease patients [1]. This method directly measures platelet function by measuring platelet adhesion to platelet-specific protein patterns using a simple, optical counting technique. The patterned surfaces are designed so that a single platelet adheres to a single protein spot and for imaging purposes, the proteins patterned on the surface are labelled with a fluorescent dye, as are the platelets that adhere to the patterned surface. Following image acquisition, the occupied (i.e. covered by a platelet) protein spots in each sample must be enumerated. The result, calculated as percent adhesion, constitutes a direct and straightforward measurement of platelet adhesion and, therefore, platelet function.

description: Scanning tunneling microscopy (STM) can be used to detect inelastic spin transitions in magnetic nano-structures comprising only a handful of atoms. Here we demonstrate that STM can uniquely identify the electrostatic spin crossover effect, whereby the exchange interaction between two magnetic centers in a magnetic molecule changes sign as a function of an external electric field. The fingerprint of such effect is a large drop in the differential conductance as the bias increases. Crucially in the case of a magnetic dimer the spin crossover transition inverts the order between the ground state and the first excited state, but does not change their symmetry. This means that at both sides of the conductance drop associated to the spin crossover transition there are two inelastic transition between the same states. The corresponding conductance steps split identically in a magnetic field and provide a unique way to identify the electrostatic spin crossover.

description: Phenolic compounds (quercetin, rutin, cyanidin, tangeretin, hesperetin, curcumin, resveratrol, etc.) are known to have health-promoting effects and they are accepted as one of the main proposed nutraceutical group. However, their application is limited owing to the problems related with their stability and water solubility as well as their low bioaccessibility and bioavailability. These limitations can be overcome by encapsulating phenolic compounds by physical, physicochemical and chemical encapsulation techniques. This review focuses on the effects of encapsulation, especially lipid-based techniques (emulsion/nanoemulsion, solid lipid nanoparticles, liposomes/nanoliposomes, etc.), on the digestibility characteristics of phenolic compounds in terms of bioaccessibility and bioavailability.
title: Tracking Hand Trajectory as a Preliminary Study for Hand Hygiene Stages

Year: 2019

description: The process of hand washing involves complex hand movements. There are six principal sequential steps for washing hands as per the World Health Organisation (WHO) guidelines. In this work, a preliminary analysis was undertaken in order to develop an automated image processing system for tracking and classification of two-handed dynamic gestures involved in hand washing. To facilitate this study, videos of healthcare workers who were engaged in washing hands were sourced from the internet. The videos were analysed in order to extract the unique features of two-handed gestures associated with all hand hygiene (HH) stages. The combination of these unique features can be used to detect each HH stage. In the video recordings, the hand trajectory was found to be linear or circular for all six HH stages. In this paper, we attempt to track hand trajectory with the help of 2.5 Mega Pixel ELP-USB cameras and using an image processing approach for skin detection and the contour-centroid detection method. The YCbCr colour space is invariant to illumination intensity and therefore it was selected for the skin detection method. This work concludes that cameras are suitable for tracking one hand movement- linear and circular motion as a preliminary work and can be further expanded for detecting two hand movements in hand washing.
Critical behavior of the fidelity susceptibility for the d=2 transverse-field Ising model

description: The overlap (inner product) between the ground-state eigenvectors with proximate interaction parameters, the so-called fidelity, plays a significant role in the quantum-information theory. In this paper, the critical behavior of the fidelity susceptibility is investigated for the two-dimensional tranverse-field (quantum) Ising model by means of the numerical diagonalization method. In order to treat a variety of system sizes N=12,14,...,32, we adopt the screw-boundary condition. Finite-size artifacts (scaling corrections) of the fidelity susceptibility appear to be suppressed, as compared to those of the Binder parameter. As a result, we estimate the fidelity-susceptibility critical exponent as α_F =0.715(20).

Konstruktion und Figuration dienen den Untersuchungen und Beobachtungen als Leitgedanken im Sinne zweier Pole, deren einer in der europäischen Tradition der Architektur eine stabile Verankerung umschreibt, während der andere eher das Fremde andeutet und uneindeutige Assoziationsfelder aufspannt.
description: In her contribution `Anderswohnen‘ Margitta Buchert links the relations of body and space with the easily comprehensible and at the same time existential dimension of dwelling in the tradition of philosophical and anthropological research by Martin Heidegger, Gaston Bachelard and Jacques Derrida. The research focus is on the multifaceted theoretical and constructional practice of the Dutch architect Rem Koolhaas and his twin offices OMA/AMO, whose projects and approaches are intensively discussed in the context of philosophical, architectural and art theoretical discourses. Construction and figuration serve as guiding ideas for the investigations and observations in the sense of two poles, one of which circumscribes a stable anchoring in the European tradition of architecture, while the other rather suggests the foreign and spans ambiguous fields of association.

titleType: Other
Creators: name: McEvoy, Padraic
Publisher: name: TU Dublin
Year: 2019

description: Supervised machine learning approaches for tracking objects’ positions in video typically require a large set of images in which the positions are labelled. Human labelling is time-consuming and automatic position labelling using visual markers is generally not possible because visible markers would corrupt the data. Here, we present an approach in which an object is tracked using a hidden tag that emits a PRBS audio signal. Four microphones arranged in a planar cross formation capture parallel recordings of the PRBS signal. Multilateration, using the time difference of arrival (TDoA) of the PRBS at each microphone, is used to estimate the position of the emitter. Here, we describe and evaluate the method by which the TDoAs are obtained and the emitter position is calculated. When evaluated, the approach yielded threedimensional position estimates with a mean error of 18.56cm. In its present form, the method is suitable for applications in which precision is not a priority, but three-dimensional object coordinates are required rather than two-dimensional camera view coordinates.

description: Against the background of the increasing cost and scarcity of raw materials that are required for the manufacture of cutting tools, the question of alternative cutting materials arises. Glasses and glass ceramics represent a possibility for this, the use of which has hardly been considered so far. This thesis is devoted to the question of whether cutting tools can be made from glass and glass ceramic materials at all. In addition, the question of how such tools can be used for which purposes is dealt with. First results on both questions are presented. The grinding of indexable inserts from the materials examined was possible without breaking corners and edges. Plastics can be easily machined with the tools produced. When machining aluminum, however, the tools made of glass fail completely, while those made of glass–ceramic show good results here too. These first results are intended to pave the way for further research in this area.

Within the framework of Fano's theory, continuum-bound anisotropic dressed state formalism of atom-molecule quantum dynamics is presented. This formalism is applicable in photo- and magneto-associative strong-coupling regimes. The significance of Fano effect in ultracold atom-molecule transitions is discussed. Quantum effects at low energy atom-molecule interface are important for exploring coherent phenomena in hither-to unexplored parameter regimes.

Publisher: name: TU Dublin
Year: 2019

description: In this paper an adaptation of the Eulerian Video Magnification technique is described for use with .TIFF files produced by a photo-conversion time lapse protocol for live cell microscopy, specifically for research into Acquired Immune Deficiency Syndrome. The tracking and characterisation of a protein found in Human Immunodeficiency Virus, to determine its dynamics and pathways is a key determinant in understanding the protein’s function. The aim of this algorithm is to process an image sequence in the temporal direction with the result being that changes in fluorescence for particular pixel locations, or regions of interest, are tracked and filtered thereby removing noise which is inherent with these types of images. This reduction in noise produced overall clearer results that will aid in further analysis of the live cells. In addition to this, this implementation attempts to adapt the existing EVM algorithm to aid in the analysis of photo-conversion experiments. The algorithm will decompose images into a multi-scale representation, and filter images in the temporal domain, recompose the image with amplifications applied to exaggerate particular motions in the images sequence. This paper also investigates the applicability of this magnification, to determine if it is practical in the situation of tracking protein dynamics. Modification of captured data is to be kept at a minimum to reduce the possibility of misinterpretation of the data.

description: In a ferromagnetic heterostructure, the interplay between a Rashba spin-orbit coupling and an exchange field gives rise to a current-driven spin torque. In a realistic device setup, we investigate the Rashba spin torque in the diffusive regime and report two major findings: (i) a nonvanishing torque exists at the edges of the device even when the magnetization and effective Rashba field are aligned; (ii) anisotropic spin relaxation rates driven by the Rashba spin-orbit coupling assign the spin torque a general expression ${\bm T}=T^y_{\para}(θ){\bm m}\times(\hat{\bm y}\times{\bm m})+T^y_{\bot}(θ)\hat{\bm y}\times{\bm m}+T^z_{\para}(θ){\bm m}\times(\hat{\bm z}\times{\bm m})+T^z_{\bot}(θ)\hat{\bm z}\times{\bm m}$, where the coefficients $T_{\para,\bot}^{y,z}$ depend on the magnetization direction. Our results agree with recent experiments.

description: A currently common method to design high-performance workpieces is to combine two or more materials to one compound. In this way, workpieces can be composed of the most qualified materials according to local loads. When machining high-performance workpiece compounds high quality requirements concerning the accuracy of dimension and shape as well as surface roughness must be fulfilled. However, in case of parallel machining, where the cutting edge moves from one material into the other within one cutting tool revolution, unequal cutting properties have a significant negative influence on tool wear and surface quality. Shape deviations of the surface occur, which are not detected when machining the single materials. The four most significant shape deviations that affect the workpiece quality are the material height deviation, transition deviation at the material joint as well as surface roughness deviation. This paper contains new approaches on the prediction of the surface shape that is generated by a face milling process. The focus is on the transition deviation at the material joint. It arises from a force impulse that is applied on the cutting tool and creates a wavy surface on the workpiece. This shape is predicted via cutting force prediction as well as frequency response analysis of the cutting tool and workpiece in relation to different tool holders. Furthermore, deviations between calculated surface shapes and measured surface shapes subsequent to machining tests are evaluated.
The validity of perturbation theory for the O(N) nonlinear sigma models
Creators: name: Cline, James M.

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Recently it has been claimed that ordinary perturbation theory (OPT) gives incorrect weak coupling expansions for lattice O(N) non-linear sigma models in the infinite volume limit, and in particular that the two-dimensional non-abelian models are not asymptotically free, contrary to previous findings. Here it is argued that the problem occurs only for one-dimensional infinite lattices, and that in general, OPT gives correct expansions if physical quantities are first computed on a finite lattice, and the infinite volume limit is taken at the end. In one dimension the expansion is sensitive to boundary conditions because of the severe infrared behavior, but this is not expected to happen in higher dimensions. It is concluded that spin configurations which are far from the perturbative vacuum have too small a measure in the path integral to invalidate OPT, even though they are energetically allowed for non-zero values of the coupling.

description: The winding insulation system of inverter-fed electrical machines is exposed to electrical stress due to unpredictable transient overvoltages. The voltages in the μs range happen with fast switching inverters and high DC link voltages. These high-frequency voltage overshoots can cause partial discharges and further lead to severe damage to the machines’ insulation systems, bearings which result in a reduction of their lifetime. In the present study, a high frequency hairpin stator lumped parameter model in a slot-based domain was developed and the influence of a winding scheme on such overvoltages was investigated. The parameters for the model have been calculated analytically or were derived from impedance measurements. The generation of simulation models with different winding schemes was automated and a beneficial winding scheme was determined.

description: L’analyse des événements indésirables (EI) associés aux soins s’est développée tout d’abord à l’hôpital où elle est largement utilisée comme méthode d’amélioration de la sécurité des soins. Elle commence seulement à émerger en médecine de ville et dans le secteur médicosocial (Ehpad). Il est connu que les points de transition sur le parcours de soins sont particulièrement à risque pour les patients. Après une expérience réussie de revue de morbi-mortalité (RMM) pluriprofessionnelle en médecine de ville, nous avons utilisé la même méthodologie pour expérimenter une RMM ville-hôpital (RMM-VH) qui a réuni des professionnels de santé exerçant sur un même territoire mais en des lieux différents du parcours de soins : pour les uns en ville et pour les autres à l’hôpital. Ces RMM-VH avaient pour objectif d’analyser des EI survenus lors de prises en charge impliquant les deux lieux de soins. Cet article décrit la mise en place et les résultats de cette expérimentation menée entre 2013 et 2015 sur le bassin de santé de la ville de Vienne (Isère). Les résultats de l’évaluation démontrent la faisabilité et l’intérêt des RMM-VH qui ont permis en particulier d’améliorer la communication et la coopération entre les professionnels en ville et à l’hôpital. Chaque EI analysé a en effet débouché sur au moins une action d’amélioration qui a pu être rapidement mise en place. Nous recommandons la promotion et la mise en place de RMM-VH, un outil pertinent et efficace pour améliorer la sécurité du parcours de soins.

description: In wireless communication systems, the nonlinear effect and inefficiency of power amplifier (PA) have posed practical challenges for system designs to achieve high spectral efficiency (SE) and energy efficiency (EE). In this paper, we analyze the impact of PA on the SE-EE tradeoff of orthogonal frequency division multiplex (OFDM) systems. An ideal PA that is always linear and incurs no additional power consumption can be shown to yield a decreasing convex function in the SE-EE tradeoff. In contrast, we show that a practical PA has an SE-EE tradeoff that has a turning point and decreases sharply after its maximum EE point. In other words, the Pareto-optimal tradeoff boundary of the SE-EE curve is very narrow. A wide range of SE-EE tradeoff, however, is desired for future wireless communications that have dynamic demand depending on the traffic loads, channel conditions, and system applications, e.g., high-SE-with-low-EE for rate-limited systems and high-EE-with-low-SE for energy-limited systems. For the SE-EE tradeoff improvement, we propose a PA switching (PAS) technique. In a PAS transmitter, one or more PAs are switched on intermittently to maximize the EE and deliver an overall required SE. As a consequence, a high EE over a wide range SE can be achieved, which is verified by numerical evaluations: with 15% SE reduction for low SE demand, the PAS between a low power PA and a high power PA can improve EE by 323%, while a single high power PA transmitter improves EE by only 68%.

description: L’accueil des proches en réanimation pose des difficultés pratiques et justifie un projet de soins centré sur les familles, pour lequel il existe des recommandations récentes. Nous rapportons les résultats d’une étude d’évaluation de la qualité de la relation soignants-familles dans un service de réanimation. L’objectif est de décrire le processus de soin centré sur les proches et d’analyser les risques qui lui sont associés. Pour cela, la participation de l’entourage aux soins est mesurée d’un point de vue soignant. En parallèle, les difficultés réelles et potentielles qu’éprouvent les acteurs à se reconnaître sont évaluées du point de vue des familles. Les résultats montrent qu’il n’est pas dans la culture du soignant d’autoriser l’entourage à participer aux soins car il n’en a pas la compétence. Cela pose la question de la formation et de l’accompagnement des familles. La participation de l’entourage aux soins profite d’abord aux patients et proches et moins aux conditions d’exercice des soignants. Quand la communication est bonne, l’accueil des familles s’en trouve amélioré. Cependant, on observe un risque d’épuisement des mécanismes de reconnaissance mutuelle des acteurs, au cours du séjour. Incarner le rôle d’aidant exige pour la famille une double reconnaissance par le patient et par l’équipe soignante, qui va apprécier sa capacité à développer une relation de confiance. Il en découle que l’accompagnement doit viser un partenariat qui rendra possible la personnalisation du soin.
title: Chambre des erreurs en jeu vidéo 2D : un serious game innovant en santé

description: La chambre des erreurs est un outil de simulation en santé s’inscrivant dans une démarche globale de gestion des risques associés aux soins. L’article fait le point sur cet outil et relate la mise en œuvre d’un serious game de ce type, déployé dans des établissements de santé lors de la semaine de la sécurité des patients (SSP). L’Observatoire des médicaments, des dispositifs médicaux et des innovations thérapeutiques (Omédit) de Normandie a développé ce serious game baptisé Simerror, en partenariat avec le CHU, le centre de lutte contre le cancer Henri Becquerel (CLCC) et l’université de Rouen. Objectifs. Il s’agissait de concevoir un outil numérique, ludique et facilement accessible, afin d’acquérir ou de réactualiser des connaissances sur les bonnes pratiques en sécurité des soins pour les professionnels de santé, et de rendre les usagers acteurs dans la sécurisation de leur prise en charge médicale. Méthode. Le groupe projet a travaillé en collaboration avec une équipe technique et pédagogique spécialisée dans la création de serious games. La première version a été testée en novembre 2016 par 3 établissements pilotes, lors de la SSP. Résultats. En fin de jeu, un questionnaire de satisfaction remis aux participants a montré une très grande satisfaction de leur part. Conclusion. Il est maintenant prévu d’introduire des erreurs supplémentaires, de créer différents niveaux de difficulté, des scènes supplémentaires et de proposer ce serious game en formation initiale ou continue.

description: We propose an approach to enhance and direct the spontaneous emission from isolated emitters embedded inside hyperbolic metamaterials into single photon beams. The approach rests on collective plasmonic Bloch modes of hyperbolic metamaterials which propagate in highly directional beams called quantum resonance cones. We propose a pumping scheme using the transparency window of the hyperbolic metamaterial that occurs near the topological transition. Finally, we address the challenge of outcoupling these broadband resonance cones into vacuum using a dielectric bullseye grating. We give a detailed analysis of quenching and design the metamaterial to have a huge Purcell factor in a broad bandwidth inspite of the losses in the metal. Our work should help motivate experiments in the development of single photon sources for broadband emitters such as nitrogen vacancy centers in diamond.

description: Fokussiert wird das zu Beginn des 21. Jahrhunderts latent vertraute Phänomen des fließenden Raumes, verbunden mit der Idee, damit auch eine Spezifik der Schnittstellen von Architektur und Kunst aufzuspüren. Relationen und Konzepte von „Fließen“ und „Räumen“ werden unter anderem in Referenz zu Konzepten von Georges Perec, Henri Lefebvre, Manuel Castells und Zygmunt Bauman skizziert, durch die der Blick für Dimensionen von gelebter und erlebter Räumlichkeit sowie für zeitgenössische raum-zeitliche Weltverständnisse geöffnet wird.Artikulationen und Interpretationen des fließenden Raumes in Architektur und Kunst seit der frühen Moderne finden schließlich besondere Beachtung. Der Beitrag ist ein Plädoyer für die geduldige Suche und Erforschung der unendlichen Virtualität von Raum, Zeit und Bewegung und ihre Vermittlung in der ästhetischen Praxis, um im Kontext einer transkulturellen und immer vielfältiger werdenden Gegenwart neue Qualitäten für Architekturschaffende und Kunstschaffende zu erschließen.
description: Focus is on the latently familiar phenomenon of flowing spaces at the beginning of the 21st century. This is connected with the idea of tracing a specificity of the interfaces of architecture and art. Relations and concepts of „flowing“ and „spaces“ are outlined referencing, among others, to concepts of Georges Perec, Henri Lefebvre, Manuel Castells and Zymunt Bauman, through which the view of dimensions of lived and experienced spatiality as well as contemporary spatio-temporal understandings of the world are opened. Finally, articulations and interpretations of flowing space in architecture and the arts since early modernism receive special attention. The contribution is a plea for the patient search and exploration of the infinite virtuality of space, time and movement and its mediation in aesthetic practice, in order to open up new qualities for those working in architecture and art in the context of a transcultural and increasingly diverse present.

Three-Dimensional Modelling of Ionized Gas. I. Did very massive stars of different metallicities drive the second cosmic reionization?

description: The first generation of stars that formed directly from the primordial gas played a crucial role in the early phase of the reionization of the universe. Because of the short lifetimes of these stars the metals produced in their cores were quickly returned to the environment, from which early PopII stars with a different initial mass function and different SEDs were formed, already much earlier than the time at which the universe became completely reionized at a redshift of z~6. Using a state-of-the-art model atmosphere code we calculate realistic SEDs of very massive stars (VMSs) of different metallicities to serve as input for the 3-dimensional multi-frequency radiative transfer code we have developed to simulate the temporal evolution of the ionization of the inhomogeneous interstellar and intergalactic medium, using multiple stellar clusters as sources of ionizing radiation. Our tool handles distributions of numerous radiative sources characterized by high resolution synthetic SEDs, and yields occupation numbers of the required energy levels of the most important elements which are treated in NLTE consistently with the 3d radiative transfer. We further demonstrate that the increasing metallicity of the radiative sources in the transition from PopIII stars to PopII stars has a strong impact on the hardness of the emitted spectrum, and hence on the reionization history of helium. A top-heavy stellar mass distribution characterized by VMSs forming in chemically evolved clusters of high core mass density may not only provide the progenitors of intermediate-mass and supermassive black holes (SMBHs), but also play an important role for the reionization of HeII. The number of VMSs required to reionize HeII by a redshift of z~2.5 is astonishingly close to the number of VMSs required to explain galactic SMBHs if one assumes that these have been formed by mergers of smaller black holes.

Intragenomic polymorphisms in the ITS region of high-quality genomes of the Hypoxylaceae (Xylariales, Ascomycota)

description: The internal transcribed spacer (ITS) region of the ribosomal DNA (rDNA) has been established (and is generally accepted) as a primary “universal” genetic barcode for fungi for many years, but the actual value for taxonomy has been heavily disputed among mycologists. Recently, twelve draft genome sequences, mainly derived from type species of the family Hypoxylaceae (Xylariales, Ascomycota) and the ex-epitype strain of Xylaria hypoxylon have become available during the course of a large phylogenomic study that was primarily aimed at establishing a correlation between the existing multi-gene-based genealogy with a genome-based phylogeny and the discovery of novel biosynthetic gene clusters encoding for secondary metabolites. The genome sequences were obtained using combinations of Illumina and Oxford nanopore technologies or PacBio sequencing, respectively, and resulted in high-quality sequences with an average N50 of 3.2 Mbp. While the main results will be published concurrently in a separate paper, the current case study was dedicated to the detection of ITS nrDNA copies in the genomes, in an attempt to explain certain incongruities and apparent mismatches between phenotypes and genotypes that had been observed during previous polyphasic studies. The results revealed that all of the studied strains had at least three copies of rDNA in their genomes, with Hypoxylon fragiforme having at least 19 copies of the ITS region, followed by Xylaria hypoxylon with at least 13 copies. Several of the genomes contained 2–3 copies that were nearly identical, but in some cases drastic differences, below 97% identity were observed. In one case, ascribable to the presence of a pseudogene, the deviations of the ITS sequences from the same genome resulted in only ca. 90% of overall homology. These results are discussed in the scope of the current trends to use ITS data for species recognition and segregation of fungi. We propose that additional genomes should be checked for such ITS polymorphisms to reassess the validity of this non-coding part of the fungal DNA for molecular identification. © 2020, The Author(s).
