description: Gould's Belt is a flat local system composed of young OB stars, molecular clouds and neutral hydrogen within 500 pc from the Sun. It is inclined about 20 degrees to the galactic plane and its velocity field significantly deviates from rotation around the distant center of the Milky Way. We discuss possible models of its origin: free expansion from a point or from a ring, expansion of a shell, or a collision of a high velocity cloud with the plane of the Milky Way. Currently, no convincing model exists. Similar structures are identified in HI and CO distribution in our and other nearby galaxies.

description: Careful immunological examination of patients is of crucial importance in diagnosis of DM type 1 and its differentiation from DM type 2. Detection of pronounced immunological changes in cell-mediated immunity, and specific auto-antibodies allows the auto-immune origin of DM being established with high degree of confidence. A reliable dependence of specific auto-antibody levels on patients’ age and remoteness of disease is established. It is the GAD antibody that is first appeared in subjects with predilection to DM type 1, and they reach the highest levels. Undoubtedly, the detection of specific autoantibodies in DM is a prerequisite test for confirmation of auto-immune origin of disease. In DM type 1, there is a significantly augmented cell-mediated mechanism of immune response, mainly due to helper cell activity. It is the activation of effector T-helpers which is believed to be associated with development of autoimmune damage to pancreatic tissue leading to DM type 1
Particular type of gap in the spectrum of multiband superconductors

description: We show, that in contrast to the free electron model (standard BCS model), a particular gap in the spectrum of multiband superconductors opens at some distance from the Fermi energy, if conduction band is composed of hybridized atomic orbitals of different symmetries. This gap has composite superconducting-hybridization origin, because it exists only if both the superconductivity and the hybridization between different kinds of orbitals are present. So for many classes of superconductors with multiorbital structure such spectrum changes should take place. These particular changes in the spectrum at some distance from the Fermi level result in slow convergence of the spectral weight of the optical conductivity even in quite conventional superconductors with isotropic s-wave pairing mechanism.

description: Trabajo de grado para optar al título de Licenciado en Física de la Universidad de Oriente // Se realizó un estudio utilizando los epicentros post-sísmicos registrados en la red temporal RESICA, luego del evento de Cariaco de 1997 (Ms = 6,8), para estimar la estructura cortical de la cuenca del Golfo de Cariaco. Se generaron secciones sísmicas utilizando los sismos secundarios como fuentes de energía, identificándose en cuatro de ellas, las fases corticales Pg y Sg, y en una, reflexiones del Moho (fases PM y SM) ubicándolo a una profundidad de 34 km. Los tiempos de llegada para las fases identificadas se utilizaron para generar modelos corticales bidimensionales para el área de estudio (ondas P y ondas S). El modelo presenta una primera capa de 180 m de espesor y velocidad promedio para las ondas P de 2 km/s, que puede interpretarse como los sedimentos de la cuenca del Golfo de Cariaco. La segunda capa corresponde a formaciones calizas y/o metamórficas de la Serranía del Interior, hasta una profundidad de 3,5 km con velocidades entre 4,85 y 5,40 km/s, seguida por una capa de transición a la corteza cristalina, hasta una profundidad de 8,5 km con velocidades entre 5,7 y 6,0 km/s. A partir de una profundidad de 8,5 km, se obtuvieron velocidades superiores a 6,5 km/s, que corresponden con las velocidades reportadas para la corteza media o inferior. El modelo cortical para las ondas S se obtuvo a partir del modelo para las ondas P, mediante la relación de Poisson (Vp/Vs), validándose mediante los tiempos de llegadas de las fases Sg y SM.

description: We examine the two-photon exchange corrections to elastic electron-proton scattering within a dispersive approach, including contributions from both Nucleon and Delta intermediate states. The dispersive analysis avoids off-shell uncertainties inherent in traditional approaches based on direct evaluation of loop diagrams, and guarantees the correct unitary behavior in the high energy limit. Using empirical information on the electromagnetic nucleon elastic and N-Delta transition form factors, we compute the two-photon exchange corrections both algebraically and numerically. Results are compared with recent measurements of e+p to e-p cross section ratios from the CLAS, VEPP-3 and OLYMPUS experiments, as well as with polarization transfer observables.

description: In recent decades, University has undergone various changes, in relation to the purposes, functions and targets of its actions, and has called to transit from a cultural transmission, centred on content and dedicated to the few, to a mass education, aimed at promoting significant learning and skills as much as possible. These innovations must be followed by as many important transformations in methods and tools adopted by the professors in both teaching and evaluation. Because university teachers are able to review concepts and practices according to the new functions attributed to University, appropriate training courses should be organized. We present the emerging issues in this regard, in particular by focusing on the problematic aspects of the evaluation. We therefore describe the intervention carried out about this topic by the University of Turin (IRIDI Project) and we take into account the main results obtained. Formare i docenti universitari alla valutazione degli apprendimenti: istanze teoriche ed esiti di ricerca Negli ultimi decenni l’università è stata oggetto di numerosi cambiamenti, in relazione agli scopi, alle funzioni, e ai destinatari delle sue azioni, ed è stata chiamata a transitare, da una trasmissione culturale, centrata sui contenuti, dedicata a pochi, ad una formazione di massa, volta a promuovere apprendimenti significativi e competenze quanto più possibile. A queste innovazioni devono seguire altrettante importanti trasformazioni dei metodi e degli strumenti adottati dai docenti universitari sia nella didattica che nella valutazione. Perché chi insegna sia in grado di rivedere concezioni e pratiche secondo le nuove funzioni attribuite all’università, è opportuno che siano organizzati percorsi adeguati di formazione. Presenteremo le istanze emergenti a tal proposito, in particolare centrandoci sugli aspetti problematici della valutazione. Descriveremo quindi un intervento, realizzato in quest’ambito dall’Università di Torino (Progetto IRIDI) e daremo conto dei principali esiti ottenuti.

description: We propose a scheme for authentication of physical keys that are materialized by optical multiple-scattering media. The authentication relies on the optical response of the key when probed by randomly selected coherent states of light, and the use of standard wavefront-shaping techniques that direct the scattered photons coherently to a specific target mode at the output. The quadratures of the electromagnetic field of the scattered light at the target mode are analysed using a homodyne detection scheme, and the acceptance or rejection of the key is decided upon the outcomes of the measurements. The proposed scheme can be implemented with current technology and offers collision resistance and robustness against key cloning.

description: The work aims to present and discuss the evidence supporting peer assessment to improve the academic performance of students in higher education by conducting an overview of meta-analyses. Meta-analyses were selected on the basis of the following selection criteria: (i) inclusion of the university context (ii) inclusion of only studies with experimental or quasi-experimental designs; (iii) description of the activities carried out in the control group during the experiment. The results show that peer evaluation has a moderate level of effectiveness on students’ academic performance. Peer assessment strategies with a high level of structure that include students training on evaluation, the use of explicit and quantitative criteria and the mediation of the computer are the key elements to make peer assessment a practice of high effectiveness to enhance students’ performance. L’efficacia della valutazione fra pari sulle performance degli studenti universitari. Evidenze di una overview di meta-analisi Il contributo si propone di presentare e discutere le evidenze a supporto della valutazione fra pari per migliorare le performance accademiche degli studenti universitari attraverso la conduzione di una overview di meta-analisi. Le meta-analisi sono state selezionate sulla base dei seguenti criteri di selezione: (i) inclusione del contesto universitario (ii) inclusione di soli studi con disegni sperimentali e/o quasi-sperimentali; (iii) indicazione delle attività condotte nel gruppo di controllo durante la sperimentazione. I risultati delle due meta-analisi selezionate (Double et al., 2019, Li et al., 2020) mostrano che la valutazione fra pari ha un livello moderato di effetto sulle performance accademiche degli studenti. In particolare emerge che modalità strutturate e sistematiche che includono la formazione degli studenti alla valutazione, l’utilizzo di criteri espliciti e quantitativi, e la mediazione del computer, siano la chiave per rendere la valutazione fra pari una pratica di elevata efficacia per l’apprendimento degli studenti.

description: For the first time, we have reported in this study an ab initio investigation on elastic properties, Debye temperature, Mulliken population, Vickers hardness, and charge density of superconducting ScRhP and ScIrP phosphides. The optimized cell parameters show fair agreement with experimental results. The elastic constants and moduli, Poisson's as well as Pugh's ratio and elastic anisotropy factors have also been calculated to understand the mechanical behavior of these ternary compounds. Their mechanical stability is confirmed via the calculated elastic constants. The calculated values for Poisson's and Pugh's ratio indicate the ductile nature of these compounds. ScIrP is expected to be elastically more anisotropic than ScRhP. The estimated value of Debye temperature predicts that ScRhP is thermally more conductive than ScIrP and the phonon frequency in ScRhP is higher than that in ScIrP. The hardness of ScRhP is lower due to the presence of anti-bonding Rh-Rh in ScRhP. The investigated electronic structure predict that the metallic conductivity of ScRhP reduces significantly when Rh is replaced with Ir. The main contribution to the total density of states (TDOS) at Fermi-level (EF) comes from the d-electrons of Sc and Rh/Ir in both compounds. These two ternary compounds are characterized mainly by metallic and covalent bonding with little ionic contribution. As far as superconductivity is concerned, the matrix elements of electron-phonon interaction are noticeably enhanced in ScIrP compared to that in ScRhP.

The Great Sumatran Fault Strike-slip Syntaxes in North Sumatra: New Insights From DEM and Fieldwork Data Analyses

description: Oblique subduction produces slip partitioning or decoupling, in which underthrusting of the subducting slab accommodates the margin-normal component of slip while a trench-parallel strike-slip fault accommodates margin-parallel slip. This process triggers the individualization of slivers of lithosphere between the trench slope and the large-scale strike-slip fault, that control the location of earthquakes and volcanic eruptions. This tectonic setting is seen in the Sumatran section of the Sunda arc-trench system, in which the Great Sumatran Fault (GSF) acts as the main strike-slip system. The accurate definition of the structure and geometry of the GSF, as well as that of its main splays, allow proper constraints on the relative motion of the fore-arc sliver plate and its internal deformation. We present a detailed structural analysis on the basis of GDEM and outcrop data at the northernmost tip of Sumatra, including the northwest islands (i.e., between 4,5N and 6N). In this area, we identify two main deformation domains along the GSF, in relation to a western and an eastern branch. The GSF's splays form the structural highs bounding the Aceh Basin as well as distinctive offshore strike-slip syntaxes responsible for the formation of the NW Sumatra islands. Fieldwork observations in relation to the western branch of the GSF show strike-slip or oblique-slip motions and roughly N-S main stress indicators. A >500m2 fault plane exposure shows well-preserved calcite crystallizations and slickenlines, which mark a transition from pure strike to oblique-slip during N-S transpression. In the offshore, the Pulau Aceh islands developed as a transpressional system of thrust splays splitting westwards from the NNW-SSE western trending line of the GSF. These top-to-the-north thrusts, which become younger northward, formed by N-S to NE-SW main stresses. A tectonic restoration based on the geometry of the thrust system points to >20% shortening accommodated by pure reverse dip-slip. The eastern branch of the GSF built the Pulau Weh Island, a tens-of-kms scale Riedel system, which principal stress axis is N-S. The GSF eastern branch further bifurcates in Pulau Weh, resulting in the development of two NNW-trending ridges to the sides of the island, which are parallel to the main deformation zone. Synthetic R and P systems, with N and NW orientations, are marked regionally by structural highs. The strike-slip syntaxes and the wide distribution of deformation of and within the Sumatra fore-arc sliver document the delocalization of the GSF system. More than 20% of the strike-slip motion in the GSF is accommodated by pure contraction and similar or larger percentages are expected from associated fault splays and strike-slip systems at oblique angles.

description: The role of rescaling (expansion or squeezing) of quantized skyrmions is studied for the spectrum of baryons beginning with nucleon and $Δ(1232)$, and with flavors strangeness, charm or beauty. The expansion of skyrmions due to the centrifugal forces has influence on the masses of baryons without flavor ($N$ and especially $Δ$). The rescaling of skyrmions has smaller influence on the spectrum of strange baryons, it is more important for the case of charm, and is crucial for baryons with beauty quantum number, where strong squeezing takes place. Two competing tendencies are clearly observed: expansion of skyrmions when isospin (or spin) increases, and squeezing with increasing mass of the flavor. For the case of beauty baryon $Λ_b$ satisfactory agreement with data can be reached for the value $r_b= F_B/F_π\simeq 2.6 $, for the case of $Σ_b$ there should be $r_b\sim 2$, so for the beauty flavor the method seems to be not quite satisfactory because of certain intrinsic discrepances. Some pentaquark states with hidden strangeness, charm or beauty are considered as well.

description: Die Arbeit setzt sich zum Ziel zu zeigen wie mittels eines nutzerorientierten Immobilienmanagements die Performance der Immobilie gesteigert werden kann. Dabei stehen Büroimmobilien im Fokus in denen Mitarbeiter als Nutzer mit ihren Tätigkeiten Wertschöpfung im Sinne der Unternehmensziele vollbringen. Die Unternehmen werden als Corporates oder Non-Property Unternehmen bezeichnet. In dieser Arbeit wird speziell die Operating Performance als Teil der Immobilienperformance adressiert. Durch eine Fokussierung auf den Nutzer und dessen Arbeitsperformance soll die Nutzungsqualität der Immobilie erhöht werden. Die Arbeit definiert zunächst die Wirkungsparameter und -beziehungen zwischen Immobilien und deren Nutzern und betrachtet auch psychologische Grundlagenmodelle sowie die neuen Arbeitswelten. Zudem werden die Möglichkeiten der Bewertung der Performance im laufenden Betrieb diskutiert. Anhand eines systematischen Literaturüberblicks werden Partialmodelle zu den Wirkungszusammenhängen aufgestellt und ein allumfassendes Rahmenmodell konzipiert. In den anschließenden Fallstudien werden Open Space Bürokonzepte auf ihre Nutzertauglichkeit hin untersucht. Sowohl in der Literaturanalyse als auch in den beiden Fallstudien wird vor allem die Herausforderung der Konzentrationsmöglichkeit aufgrund von Lärm deutlich. Zum Schluss der Arbeit werden Handlungsempfehlungen für das Corporate Real Estate Management (CREM) abgeleitet, besonders auch zur Akustik in Büros.
Towards Loop-Free Forwarding of Anonymous Internet Datagrams that Enforce Provenance

Subjects: subject: Networking and Internet Architecture (cs.NI)

description: The way in which addressing and forwarding are implemented in the Internet constitutes one of its biggest privacy and security challenges. The fact that source addresses in Internet datagrams cannot be trusted makes the IP Internet inherently vulnerable to DoS and DDoS attacks. The Internet forwarding plane is open to attacks to the privacy of datagram sources, because source addresses in Internet datagrams have global scope. The fact an Internet datagrams are forwarded based solely on the destination addresses stated in datagram headers and the next hops stored in the forwarding information bases (FIB) of relaying routers allows Internet datagrams to traverse loops, which wastes resources and leaves the Internet open to further attacks. We introduce PEAR (Provenance Enforcement through Addressing and Routing), a new approach for addressing and forwarding of Internet datagrams that enables anonymous forwarding of Internet datagrams, eliminates many of the existing DDoS attacks on the IP Internet, and prevents Internet datagrams from looping, even in the presence of routing-table loops.

description: We determine a new set of parton distribution functions (ABMP16), the strong coupling constant $α_s$ and the quark masses $m_c$, $m_b$ and $m_t$ in a global fit to next-to-next-to-leading order (NNLO) in QCD. The analysis uses the $\overline{\mathrm{MS}}$ scheme for $α_s$ and all quark masses and is performed in the fixed-flavor number scheme for $n_f=3, 4, 5$. Essential new elements of the fit are the combined data from HERA for inclusive deep-inelastic scattering (DIS), data from the fixed-target experiments NOMAD and CHORUS for neutrino-induced DIS, and data from Tevatron and the LHC for the Drell-Yan process and the hadro-production of single-top and top-quark pairs. The theory predictions include new improved approximations at NNLO for the production of heavy quarks in DIS and for the hadro-production of single-top quarks. The description of higher twist effects relevant beyond the leading twist collinear factorization approximation is refined. At NNLO we obtain the value $α_s^{(n_f=5)}(M_Z) = 0.1147 \pm 0.0008$.

Exact stabilization of entangled states in finite time by dissipative quantum circuits

description: Open quantum systems evolving according to discrete-time dynamics are capable, unlike continuous-time counterparts, to converge to a stable equilibrium in finite time with zero error. We consider dissipative quantum circuits consisting of sequences of quantum channels subject to specified quasi-locality constraints, and determine conditions under which stabilization of a pure multipartite entangled state of interest may be exactly achieved in finite time. Special emphasis is devoted to characterizing scenarios where finite-time stabilization may be achieved robustly with respect to the order of the applied quantum maps, as suitable for unsupervised control architectures. We show that if a decomposition of the physical Hilbert space into virtual subsystems is found, which is compatible with the locality constraint and relative to which the target state factorizes, then robust stabilization may be achieved by independently cooling each component. We further show that if the same condition holds for a scalable class of pure states, a continuous-time quasi-local Markov semigroup ensuring rapid mixing can be obtained. Somewhat surprisingly, we find that the commutativity of the canonical parent Hamiltonian one may associate to the target state does not directly relate to its finite-time stabilizability properties, although in all cases where we can guarantee robust stabilization, a (possibly non-canonical) commuting parent Hamiltonian may be found. Beside graph states, quantum states amenable to finite-time robust stabilization include a class of universal resource states displaying two-dimensional symmetry-protected topological order, along with tensor network states obtained by generalizing a construction due to Bravyi and Vyalyi. Extensions to representative classes of mixed graph-product and thermal states are also discussed.

description: We propose a marginally stable optical resonator suitable for atom interferometry. The resonator geometry is based on two flat mirrors at the focal planes of a lens that produces the large beam waist required to coherently manipulate cold atomic ensembles. Optical gains of about 100 are achievable using optics with part-per-thousand losses. The resulting power build-up will allow for enhanced coherent manipulation of the atomic wavepackets such as large separation beamsplitters. We study the effect of longitudinal misalignments and assess the robustness of the resonator in terms of intensity and phase profiles of the intra-cavity field. We also study how to implement atom interferometry based on Large Momentum Transfer Bragg diffraction in such a cavity.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Although there is no shortage of clustering algorithms proposed in the literature, the question of the most relevant strategy for clustering compositional data (i.e., data made up of profiles, whose rows belong to the simplex) remains largely unexplored in cases where the observed value of an observation is equal or close to zero for one or more samples. This work is motivated by the analysis of two sets of compositional data, both focused on the categorization of profiles but arising from considerably different applications: (1) identifying groups of co-expressed genes from high-throughput RNA sequencing data, in which a given gene may be completely silent in one or more experimental conditions; and (2) finding patterns in the usage of stations over the course of one week in the Velib' bicycle sharing system in Paris, France. For both of these applications, we focus on the use of appropriately chosen data transformations, including the Centered Log Ratio and a novel extension we propose called the Log Centered Log Ratio, in conjunction with the K-means algorithm. We use a nonasymptotic penalized criterion, whose penalty is calibrated with the slope heuristics, to select the number of clusters present in the data. Finally, we illustrate the performance of this clustering strategy, which is implemented in the Bioconductor package coseq, on both the gene expression and bicycle sharing system data.

description: Among the Milky Way satellites discovered in the past three years, Triangulum II has presented the most difficulty in revealing its dynamical status. Kirby et al. (2015a) identified it as the most dark matter-dominated galaxy known, with a mass-to-light ratio within the half-light radius of 3600 +3500 -2100 M_sun/L_sun. On the other hand, Martin et al. (2016) measured an outer velocity dispersion that is 3.5 +/- 2.1 times larger than the central velocity dispersion, suggesting that the system might not be in equilibrium. From new multi-epoch Keck/DEIMOS measurements of 13 member stars in Triangulum II, we constrain the velocity dispersion to be sigma_v < 3.4 km/s (90% C.L.). Our previous measurement of sigma_v, based on six stars, was inflated by the presence of a binary star with variable radial velocity. We find no evidence that the velocity dispersion increases with radius. The stars display a wide range of metallicities, indicating that Triangulum II retained supernova ejecta and therefore possesses or once possessed a massive dark matter halo. However, the detection of a metallicity dispersion hinges on the membership of the two most metal-rich stars. The stellar mass is lower than galaxies of similar mean stellar metallicity, which might indicate that Triangulum II is either a star cluster or a tidally stripped dwarf galaxy. Detailed abundances of one star show heavily depressed neutron-capture abundances, similar to stars in most other ultra-faint dwarf galaxies but unlike stars in globular clusters.

description: Agriculture is the main anchor of the Eswatini economy and profitability in this sector still remains vital for sustainable development of the economy. This study investigated the factors affecting profitability of smallholder vegetable farmers in the Shiselweni region. Primary data was obtained using a structured questionnaire and personal interviews from 60 vegetable farmers. Data was analyzed using descriptive statistics, enterprise budget, profitability ratios and multiple linear regression models. The SPSS software was used. The results showed that the mean age of the vegetable farmers was found to be 50.5 years, the mean household size was 8 people, mean farming experience was 3 years, mean farm size was 3 hectares and the majority of the farmers had high school education. The net income of smallholder vegetable farmers was E5810.30. The results of the multiple linear regression analysis revealed that land size, gender, household size, had a direct relationship with profitability of vegetable production while age, education, experience, income and labour had a negative relationship. Farmers requested that the subsidized farm inputs should arrive on time, new engines be bought for them and dams be constructed to generate irrigation water in winter

Superradiance in rotating stars and pulsar-timing constraints on dark photons

description: In the presence of massive bosonic degrees of freedom, rotational superradiance can trigger an instability that spins down black holes. This leads to peculiar gravitational-wave signatures and distribution in the spin-mass plane, which in turn can impose stringent constraints on ultralight fields. Here, we demonstrate that there is an analogous spindown effect for conducting stars. We show that rotating stars amplify low frequency electromagnetic waves, and that this effect is largest when the time scale for conduction within the star is of the order of a light crossing time. This has interesting consequences for dark photons, as massive dark photons would cause stars to spin down due to superradiant instabilities. The time scale of the spindown depends on the mass of the dark photon, and on the rotation rate, compactness, and conductivity of the star. Existing measurements of the spindown rate of pulsars place direct constraints on models of dark sectors. Our analysis suggests that dark photons of mass $m_V \sim 10^{-12}$ eV are excluded by pulsar-timing observations. These constraints also exclude superradiant instabilities triggered by dark photons as an explanation for the spin limit of observed pulsars.

The analytic properties of the quark propagator from an effective infrared interaction model

description: In this paper I investigate the analytic properties of the quark propagator Dyson-Schwinger equation (DSE) in the Landau gauge. In the quark self-energy, the combined gluon propagator and quark-gluon vertex is modeled by an effective interaction (the so-called Maris-Tandy interaction), where the ultraviolet term is neglected. This renders the loop integrand of the quark self-energy analytic on the cut-plane -Pi < arg(x) < Pi of the square of the external momentum. Exploiting the simplicity of the truncation, I study solutions of the quark propagator in the domain x in [-5.1,0] GeV^2 X i[0,10.2] GeV^2. Because of a complex conjugation symmetry, this region fully covers the parabolic integration domain for Bethe-Salpeter equations (BSEs) for bound state masses of up to 4.5 GeV. Employing a novel numerical technique that is based on highly parallel computation on graphics processing units (GPUs), I extract more than 6500 poles in this region, which arise as the bare quark mass is varied over a wide range of closely spaced values. The poles are grouped in 23 individual 'trajectories', that capture the movement of the poles in the complex region as the bare mass is varied. The raw data of the pole locations and -residues is provided as supplemental material, which can be used to parametrize solutions of the complex quark propagator for a wide range of bare mass values and for large bound state masses. This study is a first step towards an extension of previous work on the analytic continuation of perturbative one-loop integrals, with the long-term goal of establishing a framework that allows for the numerical extraction of the analytic properties of the quark propagator with a truncation that extends beyond the rainbow by making adequate adjustments in the contour of the radial integration of the quark self-energy.
