description: We derive the Lax connection of the free fermion model on a lattice starting from the fermionic formulation of Bazhanov-Stroganov's three-parameter elliptic parametrization for the R-operator. It results in the Yang-Baxter and decorated Yang-Baxter equations of difference type in one of the spectral parameters, which is the most suitable form to obtain any relativistic model of free fermions in the continuous limit.

description: The stellar populations in the outer Galactic disk are nowadays a subject of wide interest. To contribute to a better picture of this part of the Galaxy, we have studied the nature of five marginally investigated star clusters (Collinder 74, Berkeley 27, Haffner 8, NGC 2509, and VdB-Hagen 4) by means of accurate CCD photometry in the V and I pass-bands. These clusters are in fact located in the Third Galactic Quadrant. We aim to obtain the basic parameters of these objects, which in some cases are still disputed in the literature. In the case of VdB-Hagen 4 we provide the first estimate of its fundamental parameters, while for Haffner 8 we present the first CCD photometry. The analysis is based on the comparison between field stars decontaminated Color Magnitude Diagrams and stellar models. Particular care is devoted to the assessment of the data quality, and the statistical field stars decontamination. The library of stellar isochrones from Girardi et al. (2000) is adopted in this study. The analysis we carried out allowed us to solve a few inconsistencies in the literature regarding Haffner 8 and NGC 2509. Collinder 74 is found to be significantly older than reported before. VdB-Hagen 4 is a young open cluster located more than 20 kpc from the Galactic center. Such an extreme distance is compatible with the cluster belonging to the Norma-Cygnusarm.

description: The classical theory of modulation instability (MI) attributed to Bespalov-Talanov in optics and Benjamin-Feir for water waves is just a linear approximation of nonlinear effects and has limitations that have been corrected using the exact weakly nonlinear theory of wave propagation. We report results of experiments in both, optics and hydrodynamics, which are in excellent agreement with nonlinear theory. These observations clearly demonstrate that MI has wider band of unstable frequencies than predicted by the linear stability analysis. The range of areas where the nonlinear theory of MI can be applied is actually much larger than considered here.

description: We analyze the behavior of a spinning particle in gravity, both from a quantum and a classical point of view. We infer that, since the interaction between the space-time curvature and a spinning test particle is expected, then the main features of such an interaction can get light on which degrees of freedom have physical meaning in a quantum gravity theory with fermions. Finally, the dimensional reduction of Papapetrou equations is performed in a 5-dimensional Kaluza-Klein background and Dixon-Souriau results for the motion of a charged spinning body are obtained.

Αρχικά επιχειρήσαμε να κάνουμε μια σύντομη επισκόπηση του πρώιμου μοναχισμού. Στη συνέχεια παρουσιάσαμε τα βιογραφικά στοιχεία του συγγραφέα, το θέμα της αυθεντικότητας του κειμένου, το σκοπό συγγραφής του και ακολούθως επιχειρήσαμε μια ανάλυση της δομής και του περιεχομένου των 94 κεφαλαίων του Βίου. Επίσης θίξαμε το θέμα των επιρροών στο κείμενο του Βίου, τόσο των βιβλικών όσο και των φιλοσοφικών. Επιπρόσθετα επιχειρήσαμε τη βιογράφηση του προσώπου του Μεγάλου Αντωνίου και παρουσιάσαμε τις ασκητικές, αγιολογικές και ιστορικές πηγές, στις οποίες γίνεται αναφορά στο Μέγα Αντώνιο. Ασχοληθήκαμε επιπλέον με τα θεολογικά στοιχεία, τα οποία προβάλλονται μέσα στο Βίο, όπως το θέμα της δαιμονολογίας, τον αγώνα του Μεγάλου Αντωνίου εναντίον των αιρέσεων και τέλος τα ιδεώδη του αναχωρητικού βίου και τις μοναχικές αρετές.
description: Subject of the present essay is the study of St Anthony’s life through a hagiological as well as a theological approach of the life of the great ascetic, based on his biography written by Athanasius the Great, which became an example of monastic biography. The essay begins with a short review of the early monasticism, followed by the presentation of the writer’s biography, the text authenticity issue as well as of the purpose of its composition and finally by an analysis of the structure and content of the 94 chapters of the Life of Anthony. The issue of both biblical and philosophical influences throughout the Life of Antony text is also raised, while there is an attempt of portraying Anthony the Great and presenting the ascetical, hagiological and historical sources referring to him. Furthermore, the essay examines the theological issues raised in the Life of Anthony, such as the demonology issue, St Anthony’s battle against heresy, the anchoritic life ideals as well as the monastic virtues.

description: This note records two results which were inexplicably omitted from our paper on Pin structures on low dimensional manifolds, [KT]. Kirby chose not to be listed as a coauthor. A Pin^- structure on a surface F induces a quadratic enhancement of the mod 2 intersection form, q: H_1(F;Z/2Z) -> Z/4Z Theorem 1.1 says that q vanishes on the kernel of the map in homology to a bounding 3-manifold. This is used by Kreck and Puppe (arXiv:0707.1599 [math.AT]) who refer for a proof to an email of the author to Kreck. A more polished and public proof seems desirable. In [KT], section 6, a Pin^- structure is constructed on a surface F dual to w_2 in an oriented 4-manifold M^4. Theorem 2.1 says that q vanishes on the Poincare dual to the image of H^1(M^4;Z/2Z) in H^1(F;Z/2Z).

description: The absence of food monitoring has contributed significantly to the increase in the population's weight. Due to the lack of time and busy routines, most people do not control and record what is consumed in their diet. Some solutions have been proposed in computer vision to recognize food images, but few are specialized in nutritional monitoring. This work presents the development of an intelligent system that classifies and segments food presented in images to help the automatic monitoring of user diet and nutritional intake. This work shows a comparative study of state-of-the-art methods for image classification and segmentation, applied to food recognition. In our methodology, we compare the FCN, ENet, SegNet, DeepLabV3+, and Mask RCNN algorithms. We build a dataset composed of the most consumed Brazilian food types, containing nine classes and a total of 1250 images. The models were evaluated using the following metrics: Intersection over Union, Sensitivity, Specificity, Balanced Precision, and Positive Predefined Value. We also propose an system integrated into a mobile application that automatically recognizes and estimates the nutrients in a meal, assisting people with better nutritional monitoring. The proposed solution showed better results than the existing ones in the market. The dataset is publicly available at the following link http://doi.org/10.5281/zenodo.4041488

description: We present early-time ($t < +50$ days) observations of SN 2019muj (= ASASSN-19tr), one of the best-observed members of the peculiar SN Iax class. Ultraviolet and optical photometric and optical and near-infrared spectroscopic follow-up started from $\sim$5 days before maximum light ($t_{max}(B)$ on $58707.8$ MJD) and covers the photospheric phase. The early observations allow us to estimate the physical properties of the ejecta and characterize the possible divergence from a uniform chemical abundance structure. The estimated bolometric light curve peaks at 1.05 $\times$ 10$^{42}$ erg s$^{-1}$ and indicates that only 0.031 $M_\odot$ of $^{56}$Ni was produced, making SN 2019muj a moderate luminosity object in the Iax class with peak absolute magnitude of $M_{V}$ = -16.4 mag. The estimated date of explosion is $t_0 = 58698.2$ MJD and implies a short rise time of $t_{rise}$ = 9.6 days in $B$-band. We fit of the spectroscopic data by synthetic spectra, calculated via the radiative transfer code TARDIS. Adopting the partially stratified abundance template based on brighter SNe Iax provides a good match with SN 2019muj. However, without earlier spectra, the need for stratification cannot be stated in most of the elements, except carbon, which is allowed to appear in the outer layers only. SN 2019muj provides a unique opportunity to link extremely low-luminosity SNe Iax to well-studied, brighter SNe Iax.

description: We propose an enhanced Time-Dependent Variational Principle (TDVP) algorithm for Matrix Product States (MPS) that integrates Clifford disentangling techniques to efficiently manage entanglement growth. By leveraging the Clifford group, which maps Pauli strings to other Pauli strings while maintaining low computational complexity, we introduce a Clifford dressed single-site 1-TDVP scheme. During the TDVP integration, we apply a global Clifford transformation as needed to reduce entanglement by iteratively sweeping over two-qubit Clifford unitaries that connect neighboring sites in a checkerboard pattern. We validate the new algorithm numerically using various quantum many-body models, including both integrable and non-integrable systems. Our results demonstrate that the Clifford dressed TDVP significantly improves entanglement management and computational efficiency, achieving higher accuracy, extended simulation times, and enhanced precision in computed observables compared to standard TDVP approaches. Additionally, we propose incorporating Clifford gates directly within the two-site 2-TDVP scheme.

description: For quantum effects to be significant in plasmas it is often assumed that the temperature over density ratio must be small. In this paper we challenge this assumption by considering the contribution to the dynamics from the electron spin properties. As a starting point we consider a multicomponent plasma model, where electrons with spin up and spin down are regarded as different fluids. By studying the propagation of Alfvén wave solitons we demonstrate that quantum effects can survive in a relatively high-temperature plasma. The consequences of our results are discussed.

In der vorliegenden Expertise analysieren Kai Maaz und Markus Lörz (Bildungsforscher am DIPF, Leibniz-Institut für Bildungsforschung und Bildungsinformation) auf Basis von PISA-Daten die Entwicklung von sozialen Disparitäten für den Zeitraum von 2000 bis 2018: Haben die sozial bedingten Unterschiede in den Lese- und Mathematikkompetenzen von Schüler:innen zu- oder abgenommen, oder sind sie gar unverändert? Es wurde auch der Frage nachgegangen, ob die zu verzeichnenden Entwicklungstrends anhand von Veränderungen in der soziodemographischen Zusammensetzung in Schulen oder der Bildungsbeteiligung von Schüler:innen erklärt werden können.

description: Applying the nonrelativistic quantum chromodynamics factorization formalism to the $Υ(1S,2S,3S)$ hadroproduction, a complete analysis on the polarization parameters $λ_θ$, $λ_{θϕ}$, $λ_ϕ$ for the production are presented at QCD next-to-leading order. With the long-distance matrix elements extracted from experimental data for the production rate and polarization parameter $λ_θ$ of $Υ$ hadroproduction, our results provide a good description for the measured parameters $λ_{θϕ}$ and $λ_ϕ$ in both the helicity and the Collins-Soper frames. In our calculations the frame invariant parameter $\tildeλ$ is consistent in the two frames. Finally, it is pointed out that there are discrepancies for $\tildeλ$ between available experimental data and corresponding theoretical predictions.

description: We consider the Hankel determinant formula of the $τ$ functions of the Toda equation. We present a relationship between the determinant formula and the auxiliary linear problem, which is characterized by a compact formula for the $τ$ functions in the framework of the KP theory. Similar phenomena that have been observed for the Painlevé II and IV equations are recovered. The case of finite lattice is also discussed.

description: It is remarkable that the primordial fluctuations as revealed by the CMB coincide with what quantum fluctuations would look like if they were stretched across the sky by accelerated cosmic expansion. It has been observed that this same stretching also brings very small -- even trans-Planckian -- length scales up to observable sizes if extrapolated far enough into the past. This potentially jeopardizes later descriptions of late-time cosmology by introducing uncontrolled trans-Planckian theoretical errors into all calculations. Recent speculations, such as the Trans-Planckian Censorship Conjecture (TCC), have been developed to avoid this problem. We revisit old arguments why the consistency of (and control over) the Effective Field Theory (EFT) governing late-time cosmology is not necessarily threatened by the descent of modes due to universal expansion, even if EFT methods may break down at much earlier times. Failure of EFT methods only poses a problem if late-time predictions rely on non-adiabatic behaviour at these early times (such as is often true for bouncing cosmologies, for example). We illustrate our arguments using simple non-gravitational examples such as slowly rolling scalar fields and the spacing between Landau levels for charged particles in slowly varying magnetic fields, for which similar issues arise and are easier to understand. We comment on issues associated with UV completions. Our arguments need not invalidate speculative ideas like the TCC but suggest they are not required by the present evidence.

description: A connection between the gauge fixed dynamics of protected operators in superconformal Yang-Mills theory in four dimensions and Calogero systems is established. This connection generalizes the free Fermion description of the chiral primary operators of the gauge theory formed out of a single complex scalar to more general operators. In particular, a detailed analysis of protected operators charged under an su(1|1)contained in psu(2,2|4) is carried out and a class of operators is identified, whose dynamics is described by the rational super-Calogero model. These results are generalized to arbitrary BPS operators charged under an su(2|3) of the superconformal algebra. Analysis of the non-local symmetries of the super-Calogero model is also carried out, and it is shown that symmetry for a large class of protected operators is a contraction of the corresponding Yangian algebra to a loop algebra.

description: Word emphasis in textual content aims at conveying the desired intention by changing the size, color, typeface, style (bold, italic, etc.), and other typographical features. The emphasized words are extremely helpful in drawing the readers' attention to specific information that the authors wish to emphasize. However, performing such emphasis using a soft keyboard for social media interactions is time-consuming and has an associated learning curve. In this paper, we propose a novel approach to automate the emphasis word detection on short written texts. To the best of our knowledge, this work presents the first lightweight deep learning approach for smartphone deployment of emphasis selection. Experimental results show that our approach achieves comparable accuracy at a much lower model size than existing models. Our best lightweight model has a memory footprint of 2.82 MB with a matching score of 0.716 on SemEval-2020 public benchmark dataset.

The effects of temperature, photoperiod, and leaf age on foliar senescence in western larch (larix occidentalis nutt)
Creators: name: Rosenthal, Selma Iduna
Publisher: name: University of British Columbia

description: Deciduous trees integrate environmental signals to determine the onset and rate of autumnal foliar senescence. In this thesis I studied that process by characterizing environmentally-induced foliar senescence in western larch (Larix occidentalis Nutt.). I obtained measurements from seedlings senescing outdoors and from those induced to senesce in environmentally controlled chambers. The data were examined using graphs and regressions. Findings from outdoor growing seedlings were similar to results from seedlings that senesced in growth chambers, suggesting that both experimental designs allow one to study the senescence process effectively. I quantified the timing and process of senescence as it varied with leaf age and environmental conditions. In most experiments, senescing needles displayed a decline in pigment levels first, followed by carbon assimilation and Rubisco amount, and finally, chlorophyll a/b ratio and quantum yield. Warmer air temperature delayed the onset of chlorophyll and photosynthetic decline. Extended photoperiod delayed the onset of chlorophyll decline but did not affect the timing of photosynthetic decline. Neither air temperature or photoperiod directly affected the onset of decline in chlorophyll a/b ratio. Instead, the initial decline in pigment and assimilation rates may have caused the subsequent decline in chlorophyll a/b ratio. Finally, increased leaf age accelerated the onset of decline of all measures of senescence. Environmental conditions affected not only the onset but also the rate of senescence. While extended photoperiods delayed the onset of pigment loss, the rate of photosynthetic decline, once it began, was unaffected by extended photoperiod. In contrast, seedlings grown in 8°C above ambient warmer soil had higher photosynthetic rates per unit chlorophyll than control seedlings while seedlings grown in 3°C warmer soil did not display different photosynthetic rates from control seedlings. Using new methods developed in this thesis, I provide evidence that leaves integrate temperature and photoperiod signals differently. I show that it is possible to quantify the relative importance of these conditions in stimulating autumn chloroplast senescence. Furthermore, if differences in the weather and age of the leaf are accounted for, it is possible to predict the timing of pigment loss and rate of photosynthetic decline during autumn.

description: With the ongoing growth in number of digital articles in a wider set of languages and the expanding use of different languages, we need annotation methods that enable browsing multi-lingual corpora. Multilingual probabilistic topic models have recently emerged as a group of semi-supervised machine learning models that can be used to perform thematic explorations on collections of texts in multiple languages. However, these approaches require theme-aligned training data to create a language-independent space. This constraint limits the amount of scenarios that this technique can offer solutions to train and makes it difficult to scale up to situations where a huge collection of multi-lingual documents are required during the training phase. This paper presents an unsupervised document similarity algorithm that does not require parallel or comparable corpora, or any other type of translation resource. The algorithm annotates topics automatically created from documents in a single language with cross-lingual labels and describes documents by hierarchies of multi-lingual concepts from independently-trained models. Experiments performed on the English, Spanish and French editions of JCR-Acquis corpora reveal promising results on classifying and sorting documents by similar content.

description: Gauge/string duality is a potentially important framework for addressing the properties of the strongly coupled quark gluon plasma produced at RHIC. However, constructing an actual string theory dual to QCD has so far proven elusive. In this paper, we take a partial step towards exploring the QCD plasma by investigating the thermodynamics of a non-conformal system, namely the N=2^* theory, which is obtained as a mass deformation of the conformal N=4 gauge theory. We find that at temperatures of order the mass scale, the thermodynamics of the mass deformed plasma is surprisingly close to that of the conformal gauge theory plasma. This suggests that many properties of the quark gluon plasma at RHIC may in fact be well described by even relatively simple models such as that of the conformal N=4 plasma.

description: Let $\{S_n=(X_n,W_n)\}_{n\ge0}$ be a random walk with $X_n\in \mathbb{R}$ and $W_n\in \mathbb{R}^m$. Let $τ=τ_a=\inf\{n:X_n>a\}$. The main results presented are two term asymptotic expansions for the joint distribution of $S_τ$ and $τ$ and the marginal distribution of $h(S_τ/a,τ/a)$ in the limit $a\to\infty$. These results are used to study the distribution of $t$-statistics in sequential experiments with sample size $τ$, and to remove bias from confidence intervals based on Anscombe's theorem.

description: Single pair Ethernet in combination with Ethernet endpoints provides a scalable basis for the direct control of sensors and actuators in zonal vehicle networks. As recently shown, this approach is also ideal for driving high-resolution light functions. The ability to transmit different parallel data streams to actuators opens a wide field for new applications. Here, we show a method for stabilising high-resolution light projections in driving operation. The stabilization of the light image is based on an inertial measurement unit that records vehicle movements in real-time. An algorithm in a central control unit continuously calculates correction values for the position and distortion compensation of the light distribution and sends this data to the lamp via Ethernet, preferably 10BASE-T1S. Two methods are combined in a proof of concept: predictive correction with video data rate and image shifting in the headlamp’s frame buffer at high frequency.

description: By mechanically distorting a crystal lattice it is possible to engineer the electronic and optical properties of a material. In graphene, one of the major effects of such a distortion is an energy shift of the Dirac point, often described as a scalar potential. We demonstrate how such a scalar potential can be generated systematically over an entire electronic device and how the resulting changes in the graphene work function can be detected in transport experiments. Combined with Raman spectroscopy, we obtain a characteristic scalar potential consistent with recent theoretical estimates. This direct evidence for a scalar potential on a macroscopic scale due to deterministically generated strain in graphene paves the way for engineering the optical and electronic properties of graphene and similar materials by using external strain.

description: In this work, solar cells (organic and inorganic) were examined with indentation tests in order to examine their mechanical properties. The active layer of the organic solar cells was made of blend of P3HT:PCBM. All of the six samples had the same structure of P3HT:PCBM/PEDOT:PSS/ITO; From the six samples that were examined from this category the four of them had in the interface of the active layer Au or Ag Nanoparticles. Two of these four samples were annealed whereas the other two were not. The other two samples was; a polymer only without Nanoparticles and been annealed and the other without Nanoparicles but annealed.The indentation measurements showed that the annealed samples had slightly increased their elastic modulus. In the category of inorganic solar cells, samples of crystalline Si and samples of crystalline Si coated with ITO were examined with cyclic indentation. The results showed an important increase of Hardness in both samples.This increase of Hardness was due to phase transformation of Si. When the sample was under Load the lattice changed from Diamond Cubic (FCC)/(semiconductor) to Tetragonally Body Centered structure (conductor). In the Unload phase the sample transformed to Si-III or Si-XII with BCC/Rombohedrar lattice (semiconductor/ semi-metallic) if the unloading rate was slow or in a-Si if the rate wast fast.
description: Στην παρούσα εργασία μελετήθηκαν φωτοβολταικά (οργανικά και ανόργανα) με την μέθοδο της νανο- εντύπωσης με τελικό σκοπό τη μελέτη των μηχανικών ιδιοτήτων τους. To active layer του οργανικού φωτοβολταικού σε όλα τα δείγματα ήταν από P3HT:PCBM. Μελετήθηκαν έξι δείγματα με δομή P3HT:PCBM/PEDOT:PSS/ITO. Στα τέσσερα από τα έξι δείγματα είχαν εισηχθεί νανοσωματίδια χρυσού (σε δύο) και αργύρου (στα άλλα δύο) ενώ στα υπόλοιπα δύο δεν είχαν εμφιτευτεί Νανοσωματίδια. Επίσης τρία από τα έξι αυτά δείγματα είχαν υποστεί θερμική κατεργασία (ένα χωρίσ προσμίξεις,ένα με προσμίξεις χρυσού και ένα με προσμίξεις αργύρου). Τα αποτελέσματα από τα πειράματα της Νανοεντύπωσης για αυτή την κατηγορία των υλικών έδειξαν μία μικρή αύξηση του μέτρου ελαστικότητας στα δείγματα που έιχαν υποστεί σε θερμική κατεργασία. Τα ανόργανα δέιγματα ήταν από Si και από Si επικαλυμένα με ITO. Τα αποτελέσματα από τις νανο-εντυπώσης έδειξαν μέσο κυκλικής φόρτισης και αποφόρτισης των δοκιμίων η σκληρότητά τους αυξήθηκε τουλάχιστον κατά το διπλάσιο. Αυτό οφείλεται στην αλλαγή φάσης του Si το οποίο αρχικά είναι σε κρυσταλλική δομή FCC (ημιαγώγιμη) και μετά την φόρτισή του μετατρέπεται σε β-Sn Tetragonally Body Centered δομή (αγώγιμη). Έπειτα αν η αποφόρτιση γίνει με αργό ρυθμό αλλάζει πάλι η φάση του πυριτίου και έχουμε Si-III ή Si-XII δομή με BCC/Rombohedrar πλέγμα (ημιαγωγός/semi-metallic) ενώ αν γίνει με γρήγορο ρυθμό παίρνουμε φάση άμορφου Si.

description: Hintergrund:  Limbische Enzephalitis (LE) ist eine Autoimmunerkrankung, die häufig mit Temporallappenepilepsie und subakuten Gedächtnisstörungen einhergeht. Sie wird in serologische Untergruppen eingeteilt, die sich hinsichtlich des klinischen Verlaufs, des Therapieansprechens und der Prognose unterscheiden. Mit Hilfe einer longitudinalen MRT-Analyse wurde die Hypothese aufgestellt, dass die mesiotemporale Volumetrie und die kortikale Atrophierate serotypspezifische Muster aufzeigen und den Schweregrad der Erkrankung widerspiegeln.
 Methoden:  In die Studie wurden Personen mit Antikörper-positiven (Glutaminsäure-Decarboxylase 65 [GAD], Leucine-rich Glioma-inactivated Protein 1 [LGI1], Contactin-assoziiertes Protein 2 [CASPR2] und N-Methyl-D-Aspartat-Rezeptor [NMDAR]) nicht-paraneoplastischen LE aufgenommen, die zwischen 2005 und 2019 am Universitätsklinikum Bonn behandelt wurden. Eine gesunde Kohorte wurde als Kontrollgruppe einbezogen. Subkortikale Segmentierung und kortikale Rekonstruktion der T1-gewichteten MRT-Bilder wurden mit dem longitudinalen Framework von FreeSurfer durchgeführt. Für die Untersuchung mesiotemporaler Volumina und kortikaler Dicken im Längsschnitt wurden lineare gemischte Modelle verwendet.
 Ergebnisse:  Das Amygdalavolumen war bei Krankheitsbeginn bei Personen mit LE signifikant höher (p ≤ 0,048 für alle Antikörper-Untergruppen) als bei gesunden Kontrollen und nahm im Laufe der Zeit in allen Antikörper-Untergruppen ab, außer in der GAD-Untergruppe. Es konnte eine signifikant höhere Hippocampus-Atrophierate in allen Antikörper-Untergruppen im Vergleich zu den gesunden Kontrollen (alle p ≤ 0,002) gefunden werden, außer in der GAD-Untergruppe. Die kortikalen Atrophieraten überstiegen bei Personen mit beeinträchtigtem verbalen Gedächtnis den normalen Alterungsprozess, während diejenigen, die nicht beeinträchtigt waren, sich nicht signifikant von gesunden Kontrollen unterschieden.
 Diskussion:  Die Daten zeigen höhere mesiotemporale Volumina im frühen Krankheitsstadium, was höchstwahrscheinlich auf eine ödematöse Schwellung zurückzuführen ist, gefolgt von einer Volumenreduktion und Atrophie/Hippocampus-Sklerose im späten Krankheitsstadium. Es konnte außerdem der Hinweis geliefert werden, dass LE als eine Netzwerkerkrankung angesehen werden sollte, bei der die extratemporale Beteiligung ein wichtiger Faktor für die Schwere der Erkrankung darstellt.
