title: Jesuit confession and the private absolution of heresy in sixteenth-century Italy
Creators: name: Dalton, Jessica M.
Publisher: name: University of St Andrews
Year: 2018

description: This thesis offers the first extensive explanation of a unique papal privilege conceded to the Society of Jesus in 1551. This privilege allowed the new religious order to bring former heretics back into the Catholic Church in the absolute secrecy of sacramental confession. The thesis focuses on the use of this privilege on the Italian peninsula during the sixteenth century. There, the concession of the privilege was particularly remarkable as it conflicted with the jurisdiction of the Roman Inquisition, which had been established by Pope Paul III just a decade earlier. The Roman Inquisition used judicial processes to fight the spread of Protestant heresies in the Catholic heartlands. When popes throughout the sixteenth century granted Jesuits in Italy the privilege to absolve heresy, they gave the Society a jurisdiction that undermined their very own organ for stemming religious dissent. This thesis traces the history of the privilege chronologically, using both normative documents and case studies reconstructed using material from the archives of the Society, Inquisition, papacy and temporal leaders. With this approach, the thesis corrects existing accounts of the privilege, which explain it according to the aims of individuals and institutions outside of the Society without integrating the objectives of the Jesuits who actually solicited the power. By incorporating all of these factors, the thesis offers the first detailed history of the privilege and uses that history to illuminate the early Society's relationships with the papacy and the Roman Inquisition, aspects of Jesuit history that have been subject to persistent mythologisation. By analysing the fluctuating pastoral and institutional priorities that dictated the course of the early modern Church, this thesis shows that the actions and interactions of three of the most important protagonists in early modern history - the Society, the papacy and the Inquisition - were characterised by a shared pragmatism, even if their priorities were only pushed into alignment by the crisis that the Church faced after the Protestant Reformation.

description: We report the mechanical response of a model nanocomposite system of poly(styrene) (PS)-silica to large-amplitude oscillatory shear deformations. Nonlinear behavior of PS nanocomposites is discussed with the changes in particle dispersion upon deformation to provide a complete physical picture of their mechanical properties. The elastic stresses for the particle and polymer are resolved by decomposing the total stress into its purely elastic and viscous components for composites at different strain levels within a cycle of deformation. We propose a mechanistic model which captures the deformation of particles and polymer networks at small and large strains, respectively. We show, for the first time, that chain stretching in a polymer nanocomposite obtained in large amplitude oscillatory deformation is in good agreement with the nonlinear chain deformation theory of polymeric networks.

description: We study the properties of the stellar populations in M81's outermost part, which hereafter we will term the stellar halo, using HST ACS/WFC observations of 19 fields from the GHOSTS survey. The observed fields probe the stellar halo out to a projected distance of ~ 50 kpc from the galactic center. Each field was observed in both F606W and F814W filters. The 50% completeness levels of the color magnitude diagrams (CMDs) are typically at 2 mag below the tip of the red giant branch (TRGB). Fields at distances closer than 15 kpc show evidence of disk-dominated populations whereas fields at larger distances are mostly populated by halo stars. The RGB of the M81's halo CMDs is well matched with isochrones of ~ 10 Gyr and metallicities [Fe/H] ~ -1.2 dex, suggesting that the dominant stellar population of M81's halo has a similar age and metallicity. The halo of M81 is characterized by a color distribution of width ~ 0.4 mag and an approximately constant median value of (F606W - F814W) ~ 1 mag measured using stars within the magnitude range 23.7 < F814W < 25.5. When considering only fields located at galactocentric radius R > 15 kpc, we detect no color gradient in the stellar halo of M81. We place a limit of 0.03+/-0.11 mag difference between the median color of RGB M81 halo stars at ~ 15 and at 50 kpc, corresponding to a metallicity difference of 0.08+/-0.35 dex over that radial range for an assumed constant age of 10 Gyr. We compare these results with model predictions for the colors of stellar halos formed purely via accretion of satellite galaxies. When we analyze the cosmologically motivated models in the same way as the HST data, we find that they predict no color gradient for the stellar halos, in good agreement with the observations.

description: In this paper, approaches for the realization of high-resolution periodic structures with gap sizes at sub-100 nm scale by two-photon polymerization (2PP) are presented. The impact of laser intensity on the feature sizes and surface quality is investigated. The influence of different photosensitive materials on the structure formation is compared. Based on the elliptical geometry character of the voxel, the authors present an idea to realize high-resolution structures with feature sizes less than 100 nm by controlling the laser focus position with respect to the glass substrate. This investigation covers structures fabricated respectively in the plane along and perpendicular to the major axis of voxel. The authors also provide a useful approach to manage the fabrication of proposed periodic structure with a periodic distance of 200 nm and a gap size of 65 nm.

description: In the past decades a wide range of complex processes have been developed to solve specific geospatial data integration problems. As a drawback these complex processes are often not sufficiently transferable and interoperable. We propose modularisation of the whole data integration process into reusable, exchangeable, and multi-purpose web services to overcome these drawbacks. Both a high-level split of the process into subsequent modules such as pre-processing and feature matching is discussed as well as another fine-granular split within these modules. Thereby complex integration problems can be addressed by chaining selected services as part of a geo-processing workflow. Parallelization is needed for processing massive amounts of data or complex algorithms. In this paper the two concepts of task and data parallelization are compared and examples for their usage are given. The presented work provides vector data integration within grid-computing workflows of the German Spatial Data Infrastructure Grid (SDI-Grid) project.

description: We present time-resolved photoemission experiments from a peculiar bismuth surface, Bi(114). The strong one-dimensional character of this surface is reflected in the Fermi surface, which consists of spin-polarized straight lines. Our results show that the depletion of the surface state and the population of the bulk conduction band after the initial optical excitation persist for very long times. The disequilibrium within the hot electron gas along with strong electron-phonon coupling cause a displacive excitation of coherent phonons, which in turn are reflected in coherent modulations of the electronic states. Beside the well-known A1g bulk phonon mode at 2.76 THz the time-resolved photoelectron spectra reveal a second mode at 0.72 THz which can be attributed to an optical surface phonon mode along the atomic rows of the Bi(114) surface.

description: A major obstacle to implementing Shor's quantum number-factoring algorithm is the large size of modular-exponentiation circuits. We reduce this bottleneck by customizing reversible circuits for modular multiplication to individual runs of Shor's algorithm. Our circuit-synthesis procedure exploits spectral properties of multiplication operators and constructs optimized circuits from the traces of the execution of an appropriate GCD algorithm. Empirically, gate counts are reduced by 4-5 times, and circuit latency is reduced by larger factors.

Convergence zones for Type I migration: an inward shift for multiple planet systems

description: Earth-mass planets embedded in gaseous protoplanetary disks undergo Type I orbital migration. In radiative disks an additional component of the corotation torque scaling with the entropy gradient across the horseshoe region can counteract the general inward migration, Type I migration can then be directed either inward or outward depending on the local disk properties. Thus, special locations exist in the disk toward which planets migrate in a convergent way. Here we present N-body simulations of the convergent migration of systems of low-mass (M=1-10 m_earth) planets. We show that planets do not actually converge in convergence zones. Rather, they become trapped in chains of mean motion resonances (MMRs). This causes the planets' eccentricities to increase to high enough values to affect the structure of the horseshoe region and weaken the positive corotation torque. The zero-torque equilibrium point of the resonant chain of planets is determined by the sum of the attenuated corotation torques and unattenuated differential Lindblad torques acting on each planet. The effective convergence zone is shifted inward. Systems with several planets can experience stochastic migration as a whole due to continuous perturbations from planets entering and leaving resonances.

description: Research infrastructures and services provide access to (meta)data via user interfaces and APIs. The more advanced services also support access through (Python, R, etc.) packages that users can use in computational environments. For scientific information as a particular kind of research data, the Open Research Knowledge Graph (ORKG) is an example of an advanced service that also supports accessing data from Python scripts. Since many research communities use R as the statistical language of choice, we have developed the ORKG R package to support accessing and processing ORKG data directly from R scripts. Inspired by the Python library, the ORKG R package supports a comparable set of features through a similar programmatic interface. Having developed the ORKG R package, we demonstrate its use in various applications grounded in life science and soil science research fields. As an additional key contribution of this work, we show how the ORKG R package can be used in combination with ORKG templates to support the pre-publication production and publication of machine-readable scientific information, during the data analysis phase of the research life cycle and directly in the scripts that produce scientific information. This new mode of machine-readable scientific information production complements the post-publication Crowdsourcing-based manual and NLP-based automated approaches with the major advantages of unmatched high accuracy and fine granularity.

description: In this paper we discuss the existence problem for a semi-cyclic holey group divisible design of type (n,m^t) with block size 3, which is denoted by a 3-SCHGDD of type (n,m^t). When n=3, a 3-SCHGDD of type (3,m^t) is equivalent to a (3,mt;m)-cyclic holey difference matrix, denoted by a (3,mt;m)-CHDM. It is shown that there is a (3,mt;m)-CHDM if and only if (t-1)m\equiv 0 (mod 2) and t\geq 3 with the exception of m\equiv 0 (mod 2) and t=3. When n\geq 4, the case of t odd is considered. It is established that if t\equiv 1 (mod 2) and n\geq 4, then there exists a 3-SCHGDD of type (n,m^t) if and only if t\geq 3 and (t-1)n(n-1)m\equiv 0 (mod 6) with some possible exceptions of n=6 and 8. The main results in this paper have been used to construct optimal two-dimensional optical orthogonal codes with weight 3 and different auto- and cross-correlation constraints by the authors recently.

description: Any changes to the Earth’s surface should be monitored in order to maintain and update the spatial reference system. To establish a global model of ground movements for a large area, it is important to have consistent and reliable measurements. However, in dealing with mass data, outliers may occur and robust analysis of data is indispensable. In particular, this paper will analyse Synthetic Aperture Radar (SAR) data for detecting the regional ground movements (RGM) in the area of Hanover, Germany. The relevant data sets have been provided by the Federal Institute for Geo-sciences and Natural Resources (BGR) for the period of 2014 to 2018. In this paper, we propose a data adoptive outlier detection algorithm to preprocess the observations. The algorithm is tested with different reference data sets and as a binary classifier performs with 0.99 accuracy and obtains a 0.95 F1-score in detecting the outliers. The RGMs that are observed as height velocities are mathematically modeled as a surface based on a hierarchical B-splines (HB-splines) method. For the approximated surface, a 95% confidence interval is estimated based on a bootstrapping approach. In the end, the user is enabled to predict RGM at any point and is provided with a measure of quality for the prediction.
Migration of small moons in Saturn's rings

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The motions of small moons through Saturn's rings provide excellent tests of radial migration models. In theory, torque exchange between these moons and ring particles leads to radial drift. We predict that moons with Hill radii r_H ~ 2-24 km should migrate through the A ring in 1000 yr. In this size range, moons orbiting in an empty gap or in a full ring eventually migrate at the same rate. Smaller moons or moonlets -- such as the propellers (e.g., Tiscareno et al. 2006) -- are trapped by diffusion of disk material into corotating orbits, creating inertial drag. Larger moons -- such as Pan or Atlas -- do not migrate because of their own inertia. Fast migration of 2-24 km moons should eliminate intermediate-size bodies from the A ring and may be responsible for the observed large-radius cutoff of r_H ~ 1-2 km in the size distribution of the A ring's propeller moonlets. Although the presence of Daphnis (r_H ~ 5 km) inside the Keeler gap challenges this scenario, numerical simulations demonstrate that orbital resonances and stirring by distant, larger moons (e.g., Mimas) may be important factors. For Daphnis, stirring by distant moons seems the most promising mechanism to halt fast migration. Alternatively, Daphnis may be a recent addition to the ring that is settling into a low inclination orbit in ~10^3 yr prior to a phase of rapid migration. We provide predictions of observational constraints required to discriminate among possible scenarios for Daphnis.

description: Постановка проблемы. В последние годы технология радиовидения (метод интроскопии, позволяющий с помощью радиоволн получать изображения объектов, находящихся в оптически непрозрачной среде) успешно используется для неразрушающего контроля диэлектрических материалов, используемых в ракетно-космической промышленности, в частности, теплоизоляционных покрытий ракетных баков для криогенного топлива. При этом решение обратной задачи рассеяния осложняется из-за наличия металлической поверхности бака, являющейся для электромагнитных волн идеальным отражателем. В этих условиях одним из возможных методов восстановления внутренней структуры теплоизоляционного покрытия является итеративный метод Гаусса–Ньютона с использованием функции Грина, соответствующей геометрии зондирования, и регуляризации Тихонова. В случае однородного диэлектрического полупространства (без металлической поверхности) неизвестное расстояние от плоскости регистрации радиолокационных данных до подповерхностного объекта/дефекта может быть определено даже при использовании одночастотного сигнала методом наилучшей фокусировки. Однако при наличии металлической поверхности, при моностатической конфигурации антенной системы, использовавшейся в экспериментах, данный метод не работает, так как подповерхностный объект получается практически одинаково хорошо сфокусированным на разных расстояниях, расположенных периодически, и определить истинное расстояние невозможно. Теоретические исследования показали, что мультистатическая конфигурация с разнесенными передающими и приемными антеннами позволяет решить проблему определения расстояния до объекта, однако практическая реализация требует существенной доработки оборудования. Цель. Работа посвящена получению радиоизображений объектов, расположенных в средах, ограниченных снизу металлической поверхностью. Используется метод восстановления распределения электрических свойство среды, основанный на
аппроксимации Борна при записи уравнения рассеяния и реализованный с помощью итеративного алгоритма Гаусса–Ньютона с регуляризацией Тихонова.
Результаты. Приведены результаты как вычислительных, так и физических экспериментов.
Практическая значимость. Возможность использование для неразрушающего контроля топливных баков изделий ракетно-космической техники.

description: Linear polarization measurements have been performed for $γ$-rays in $^{91}$Ru produced with the $^{58}$Ni($^{36}$Ar, $2p1n$$γ$)$^{91}$Ru reaction at a beam energy of 111 MeV. The EXOGAM Ge clover array has been used to measure the $γ$-$γ$ coincidences, $γ$-ray linear polarization and $γ$-ray angular distributions. The polarization sensitivity of the EXOGAM clover detectors acting as Compton polarimeters has been determined in the energy range 0.3$-$1.3 MeV. Several transitions have been observed for the first time. Measurements of linear polarization and angular distribution have led to the firm assignments of spin differences and parity of high-spin states in $^{91}$Ru. More specifically, calculations using a semi-empirical shell model were performed to understand the structures of the first and second (21/2$^{+}$) and (17/2$^{+}$) levels. The results are in good agreement with the experimental data, supporting the interpretation of the non yrast (21/2$^{+}$) and (17/2$^{+}$) states in terms of the $J_{\rm max}$ and $J_{\rm max}-2$ members of the seniority-three $ν(g_{9/2})^{-3}$ multiplet.

description: Although most rolling element bearings are grease lubricated, the underlying mechanisms of grease lubrication has not been fully explored. This study investigates grease film evolution with glass disc revolutions in rolling elastohydrodynamic lubrication (EHL) contacts. The evolution patterns of the grease films were highly related to the speed ranges and grease structures. The transference of thickener lumps, film thickness decay induced by starvation, and residual layer were recognized. The formation of an equilibrium film determined by the balance of lubricant loss and replenishment was analyzed. The primary mechanisms that dominate grease film formation in different lubricated contacts were clarified. ¬© 2020, The Author(s).
Stochastic Differential Games and Energy-Efficient Power Control

description: One of the contributions of this work is to formulate the problem of energy-efficient power control in multiple access channels (namely, channels which comprise several transmitters and one receiver) as a stochastic differential game. The players are the transmitters who adapt their power level to the quality of their time-varying link with the receiver, their battery level, and the strategy updates of the others. The proposed model not only allows one to take into account long-term strategic interactions but also long-term energy constraints. A simple sufficient condition for the existence of a Nash equilibrium in this game is provided and shown to be verified in a typical scenario. As the uniqueness and determination of equilibria are difficult issues in general, especially when the number of players goes large, we move to two special cases: the single player case which gives us some useful insights of practical interest and allows one to make connections with the case of large number of players. The latter case is treated with a mean-field game approach for which reasonable sufficient conditions for convergence and uniqueness are provided. Remarkably, this recent approach for large system analysis shows how scalability can be dealt with in large games and only relies on the individual state information assumption.

description: It has been built a strict mathematical model of the thermodynamic equilibrium's establishment in the originally nonequilibrium cosmological ultrarelativistic plasma for the arbitrary accelerated Universe under the assumption that scaling of interactions of elementary particles is restored at energies above the unitary limit. It is shown, that in case of Universe positive acceleration, thermodynamic equilibrium never can be completely restored.

description: In recent years, optical nanothermometers have seen huge improvements in terms of precision as well as versatility, and several research efforts have been directed at adapting novel active materials or further optimizing the temperature sensitivity. The signal-to-noise ratio of the emission lines is commonly seen as the only limitation regarding high precision measurements. The role of re-absorption caused by a population of lower energy levels, however, has so far been neglected as a potential bottleneck for both high resolution and material selection. In this work, we conduct a study of the time dependent evolution of population densities in different luminescence nanothermometer classes under the commonly used pulsed excitation scheme. It is shown that the population of lower energy levels varies when the pump source fluctuates in terms of power and pulse duration. This leads to a significant degradation in temperature resolution, with limiting values of 0.5 K for common systems. Our study on the error margin indicates that either short pulsed or continuous excitation should be preferred for high precision measurements. Additionally, we derive conversion factors, enabling the re-calibration of currently available intensity ratio measurements to the steady state regime, thus facilitating the transition from pulse regimes to continuous excitation.

description: We report the discovery of a transiting brown dwarf companion to KOI-205, a K0 main-sequence star, in a 11.720125-day period orbit. The transits were detected by the Kepler space telescope, and the reflex motion of the star was measured using radial velocity observations obtained with the SOPHIE spectrograph. The atmospheric parameters of the host stars were determined from the analysis of high-resolution, high signal-to-noise ratio ESPaDOns spectra obtained for this purpose. Together with spectrophotometric measurements recovered from the literature, these spectra indicate that the star is a mildly metallic K0 dwarf with Teff 5237 $\pm$ 60 K. The mass of the companion is 39.9 $\pm$ 1.0 MJup and its radius is 0.81 $\pm$ 0.02 RJup, in agreement with current theoretical predictions. This is the first time a bona fide brown dwarf companion is detected in orbit around a star of this type. The formation and orbital evolution of brown dwarf companions is briefly discussed in the light of this new discovery.

description: Liebe Leserinnen und Leser, kein Nachrichtentag vergeht, an dem nicht die Expertise aus der Wissenschaft gefragt ist: Ob zum russischen Angriffskrieg in der Ukraine, zur UNKlimakonferenz in Ägypten, zur Flutkatastrophe in Pakistan, zum Dürresommer, zur Energiekrise, selbst zur umstrittenen Fußballweltmeisterschaft in Katar standen und stehen Expertinnen und Experten in den Medien Rede und Antwort. Auch aus der Universität Potsdam. Wir haben sie gefragt, wie sie damit umgehen, wie es ihnen gelingt, aus der laufenden Forschung heraus aktuelle Probleme zu bewerten. Und was davon bleibt, wenn das öffentliche Interesse abebbt. Für die Potsdamer Politik- und Verwaltungswissenschaftlerin Sabine Kuhlmann besteht die Kunst darin, „außerhalb der Krise Ideen und Lösungsansätze zu verstetigen und sie tatsächlich in die Praxis umzusetzen“. In unserem Alumni- und Transfermagazin berichten wir davon, was und wie die Universität Potsdam dazu beiträgt. Wir erzählen, wie Erfindungen zu Innovationen in der Wirtschaft werden und sich Start-ups auf den Weg machen, ihr Produkt selbst zu vermarkten. Das Spektrum reicht von Meeresfrüchten auf Pflanzenbasis bis zu einer App, mit der sich Frühformen der Demenz erkennen lassen. Neben neuen Technologien kommt es aber vor allem darauf an, das an der Universität erzeugte Wissen in die Praxis zu transferieren. Deshalb stellen wir ein Programm zur Bekämpfung von Hassrede in der Schule vor oder auch eine Klettertherapie zur Behandlung von Skoliose. Und wir zeigen, wie eine Studie zur sportlichen Leistungskraft von Kindern helfen kann, den Sportunterricht zu verbessern. Den größten Teil des an der Universität produzierten Wissens tragen die Studierenden in die Welt, wenn sie nach ihrem Abschluss als Musiklehrerin in einer Schule arbeiten oder als Software-Ingenieur im eigenen Unternehmen, als Geologin nach Seltenen Erden schürfen, als Ökologe ausgelaugte Böden wieder fruchtbar machen oder als Politikerin ein Ministerium leiten. Sie alle kommen in diesem Magazin zu Wort. Oder in unserem neuen Podcast „Listen.UP“, in dem Studierende, Forschende und Alumni von ihren Transferprojekten erzählen. Von der Gründerin Ulrike Böttcher erfährt man dort zum Beispiel, wie sie mit Schnallen, Ösen und Knöpfen aus Bio- Materialien die Modeindustrie in diesem Bereich nachhaltig verändern will. Nachzulesen ist das auch in diesem Heft. Immer dort, wo das „Listen. UP“-Logo erscheint, lohnt es, zusätzlich in den Podcast hineinzuhören.

description: High pressure in-situ synchrotron X-ray diffraction experiments were performed on Ag2Te up to 42.6 GPa at room temperature and four phases were identified. Phase I (β-Ag2Te) transformed into phase II at 2.4 GPa, and phase III and phase IV emerged at 2.8 GPa and 12.8 GPa respectively. Combined with first-principles calculations, we solved the phase II and phase III crystal structures, and determined the compressional behavior of phase III. Electronic band structure calculations show that the insulating phase I with a narrow band gap first transforms into semi metallic phase II with the perseverance of topologically non trivial nature, and then to bulk metallic phase III. Density of States (DOS) calculations indicate the contrasting transport behavior for Ag2-δTe and Ag2+δTe under compression. Our results highlight pressure's dramatic role in tuning Ag2Te's electronic band structure, and its novel electrical and magneto transport behaviors.
