description: Currently, HOPS and AIPS are the primary choices for the time-consuming process of (millimeter) Very Long Baseline Interferometry (VLBI) data calibration. However, for a full end-to-end pipeline, they either lack the ability to perform easily scriptable incremental calibration or do not provide full control over the workflow with the ability to manipulate and edit calibration solutions directly. The Common Astronomy Software Application (CASA) offers all these abilities, together with a secure development future and an intuitive Python interface, which is very attractive for young radio astronomers. Inspired by the recent addition of a global fringe-fitter, the capability to convert FITS-IDI files to measurement sets, and amplitude calibration routines based on ANTAB metadata, we have developed the the CASA-based Radboud PIpeline for the Calibration of high Angular Resolution Data (rPICARD). The pipeline will be able to handle data from multiple arrays: EHT, GMVA, VLBA and the EVN in the first release. Polarization and phase-referencing calibration are supported and a spectral line mode will be added in the future. The large bandwidths of future radio observatories ask for a scalable reduction software. Within CASA, a message passing interface (MPI) implementation is used for parallelization, reducing the total time needed for processing. The most significant gain is obtained for the time-consuming fringe-fitting task where each scan be processed in parallel.

description: Recent years have witnessed a rise in global investments in the digital economy. The growing digital reach of Chinese tech companies is responsible for at least part of this transformation. Yet, little is known about how host country citizens view China’s increasing stature in the digital sphere. Focusing on Chinese investments in mobile payment platforms (CIM), this article explains citizens’ levels of approval of Chinese outward investments in the digital economy. Based on online surveys conducted in four selected Southeast Asian countries – Thailand, Malaysia, Indonesia, and the Philippines – this research shows that citizens of these four countries perceive the benefits of CIM to outweigh the risks, with approval rates to be higher for Thailand and Malaysia, and lower for Indonesia and the Philippines. We find these high levels of approval for CIM to be significantly associated with perceived personal benefit, such as price reductions and an increase in purchasing choices. By contrast, country-level factors, such as geopolitical concerns about China, do matter in some contexts, but overall show less explanatory influence. These results shed light on citizens’ views of different types of foreign investments and of China, and support previous arguments on the separation between consumer behavior and politics.

description: We provide a partial solution to the problem of defining a constructive version of Voevodsky's simplicial model of univalent foundations. For this, we prove constructive counterparts of the necessary results of simplicial homotopy theory, building on the constructive version of the Kan-Quillen model structure established by the second-named author. In particular, we show that dependent products along fibrations with cofibrant domains preserve fibrations, establish the weak equivalence extension property for weak equivalences between fibrations with cofibrant domain and define a univalent classifying fibration for small fibrations between bifibrant objects. These results allow us to define a comprehension category supporting identity types, $Σ$-types, $Π$-types and a univalent universe, leaving only a coherence question to be addressed.

description: Diese Arbeit liefert einen Überblick über die dolmetschwissenschaftliche Literatur hinsichtlich des Antizipationsbegriffs. In den ersten zwei Kapiteln werden die kognitiven Aspekte beim Simultandolmetschen dargelegt und der Antizipationsbegriff psycholinguistisch und dolmetschwissenschaftlich erklärt. Vor allem die Ansichten des russischen Dolmetschers und Dolmetschwissenschaftlers Chernov werden in einem eigenen Kapitel aufgegriffen. Der Forschungsgegenstand der vorliegenden Arbeit ist nämlich als Replikation von Chernovs Experiment zu verstehen, in welchem die Antizipationsfähigkeit von DolmetscherInnen untersucht wurde. Auch in der vorliegenden Arbeit wird die Antizipationsfähigkeit von Dolmertsch-Studierenden am Zentrum der Translationswissenschaft der Universität Wien, aber auch von professionellen Dolmetscherinnen im Sprachenpaar Deutsch - Bosnisch/Kroatisch/Serbisch untersucht.
description: This master’s thesis deals with anticipation as an interpreting strategy. The beginning chapters give an overview on the various definitions of anticipation in psychology, linguistics and interpreting science. Especially Chernov’s research work and his views on anticipation are being picked up in a separate chapter of this present thesis. By the means of an experiment, Chernov demonstrated the importance of anticipation as a special interpreting strategy. Also, the present object of research is a replication of Chernov’s experiment, in purpose of testing his hypotheses. Here as well the interpreting students’ and interpreters’ ability to anticipate is examined.

description: Despite the growing importance of nationality as an international problem, certain phases of the subject have been almost entirely neglected in the field of scientific research. The particular topic of "Statelessness" is one of these phases. This question has arrested the attention of scholars, especially since the World War, which event enormously increased the number of persons without a country. Because of the growing importance of the subject of "Statelessness", the lack of any comprehensive treatment of it, and the personal interest of the writer in the field of nationality, this work has been undertaken. The study is organized from three points of view. First, the historical development of the pertinent nationality laws of the United States is traced. Secondly, the significant interpretations of these laws, through court decisions and administrative opinions and practice are analyzed. Finally, an effort is made to offer constructive suggestions by means of which the obviously abnormal situation of statelessness may be eliminated.

For this we construct a filtered circle interpolating between the usual topological circle and a formal version of it. By mapping to schemes we produce this way an interpolation, realized in practice by the existence of a natural filtration, from Hochschild and (a filtered version of) cyclic homology to derived de Rham cohomology. In particular, we show that this recovers the filtration of Antieau and Bhatt-Morrow-Scholze. The construction of our filtered circle is based on the theory of affine stacks and affinization introduced by the third author, together with some facts about schemes of Witt vectors.

description: We introduce type-theoretic algebraic weak factorisation systems and show how they give rise to homotopy-theoretic models of Martin-Löf type theory. This is done by showing that the comprehension category associated to a type-theoretic algebraic weak factorisation system satisfies the assumptions necessary to apply a right adjoint method for splitting comprehension categories. We then provide methods for constructing several examples of type-theoretic algebraic weak factorisation systems, encompassing the existing groupoid model and cubical sets models, as well as some models based on normal fibrations

description: Consider the problem of imputing missing values in a dataset. One the one hand, conventional approaches using iterative imputation benefit from the simplicity and customizability of learning conditional distributions directly, but suffer from the practical requirement for appropriate model specification of each and every variable. On the other hand, recent methods using deep generative modeling benefit from the capacity and efficiency of learning with neural network function approximators, but are often difficult to optimize and rely on stronger data assumptions. In this work, we study an approach that marries the advantages of both: We propose *HyperImpute*, a generalized iterative imputation framework for adaptively and automatically configuring column-wise models and their hyperparameters. Practically, we provide a concrete implementation with out-of-the-box learners, optimizers, simulators, and extensible interfaces. Empirically, we investigate this framework via comprehensive experiments and sensitivities on a variety of public datasets, and demonstrate its ability to generate accurate imputations relative to a strong suite of benchmarks. Contrary to recent work, we believe our findings constitute a strong defense of the iterative imputation paradigm.

Time-Optimal Control Problem With State Constraints In A Time-Periodic Flow Field

description: This article contributes to a framework for a computational indirect method based on the Pontryagin maximum principle to efficiently solve a class of state constrained time-optimal control problems in the presence of a time-dependent flow field. Path-planning in a flow with tidal variations is an emblematic real-life task that serves as an example falling in the class of problems considered here. Under rather natural assumptions on the flow field, the problem is regular and the measure Lagrange multiplier, associated with the state constraint, is continuous. These properties (regularity and continuity) play a critical role in computing the field of extremals by solving the two-point boundary value problem given by the maximum principle. Moreover, some sufficient conditions preventing the emergence of singular control processes are given. A couple of examples of time-periodic fluid flows are studied and the corresponding optimal solutions are found.

description: Among all of the first-year graduate students enrolled in doctoral-granting physics departments, the percentage of female and racial minority students has remained unchanged for the past 20 years. The current graduate program admissions process can create challenges for achieving diversity goals in physics. In this paper, we will investigate how the various aspects of a prospective student's application to a physics doctoral program affect the likelihood the applicant will be admitted. Admissions data was collected from a large, Midwestern public research university that has a decentralized admissions process and included applicants' undergraduate GPAs and institutions, research interests, and GRE scores. Because the collected data varied in scale, we used supervised machine learning algorithms to create models that predict who was admitted into the PhD program. We find that using only the applicant's undergraduate GPA and physics GRE score, we are able to predict with 75% accuracy who will be admitted to the program.

description: In many upper-division lab courses, instructors implement multiweek student-led projects. During such projects, students may design and carry out experiments, collect and analyze data, document and report their findings, and collaborate closely with peers and mentors. To better understand cognitive, social, and affective aspects of projects, we conducted an exploratory investigation of student ownership of projects. Ownership is a complex construct that refers to, e.g., students' willingness and ability to make strategic decisions about their project. Using data collected through surveys and interviews with students and instructors at five institutions, we developed a preliminary model for student ownership of projects. Our model describes student interactions with the project during three phases: choice of topic, execution of experiment, and synthesis of results. Herein, we explicate our model and demonstrate that it maps well onto students' and instructors' conceptions of ownership and ideas presented in prior literature.

description: Understanding how adolescents integrate multiple cultures into their identity is a growing field of research in modern multicultural societies and requires psychometrically sound assessments tools. The Bicultural Identity Integration framework together with the Bicultural Identity Integration Scale 2 (BIIS-2; Huynh et al., 2018) offers an instrument that allows assessing BII with two factors (Blendedness vs. Compartmentalization and Harmony vs. Conflict). However, the psychometric properties of the BIIS-2 remain inconclusive for multicultural youth in Germany. To address this gap, we examined the psychometric properties of the BIIS-2 in a sample comprising 595 diverse ethnic minority adolescents in Germany (Mage = 13.26, SD = 1.3; 45.6% female). Contrary to the proposed two-factor structure (Huynh et al., 2018), our findings provide evidence for a four-factor structure (Blendedness, Compartmentalization, Harmony, and Conflict) which is also supported through unique associations in validation results.
Early's Raid on Washington, June-July 1864

description: Most Americans know that our national capital was captured by the British during the war of 1812, but how many realize that Washington was almost captured again during the Civil War? The stories of Bull Run, Antietam, and Gettysburg are familiar to us all, and have been widely discussed in books and periodicals. General Jubal A. Early's raid on Washington during the Civil War has not received attention comparable to its importance, however. Numerous accounts have discussed certain phases of Early's raid in detail, but none of them gives a complete picture of the raid from the time of its inception in the minds of the Confederate leaders to its ultimate failure at the very gates of Washington. I have attempted, in this thesis, to write a complete and accurate account of Early's raid, including many aspects which other writers have omitted.

description: This article concerns a class of time-optimal state constrained control problems with dynamics defined by an ordinary differential equation involving a three-dimensional steady flow vector field. The problem is solved via an indirect method based on the maximum principle in Gamkrelidze's form. The proposed computational method essentially uses a certain regularity condition imposed on the data of the problem. The property of regularity guarantees the continuity of the measure multiplier associated with the state constraint, and ensures the appropriate behavior of the corresponding numerical procedure which, in general, consists in computing the entire field of extremals for the problem in question. Several examples of vector fields are considered to illustrate the computational approach.

Parameter-based particle identification using machine learning techniques in KM3NeT/ORCA6
Creators: name: Pedrajas, Alfonso Lazo
Publisher: name: Zenodo
Year: 2022

description: Particle-identification (PID) is used in KM3NeT/ORCA6 to separate atmospheric neutrinos, which are used to study neutrino properties, from the background of atmospheric muons, and further to distinguish track- and shower-like events, allowing the identification of the neutrino flavour. For this purpose, two boosted decision trees (BDTs) have been trained independently to provide a muon score and a track score, which provide a measurement of how much do the detected events resemble the two categories. The results stated in this work promise to build the basis for event selections, which can be able to reduce the muon contamination down to the few-percent level, while keeping high signal efficiencies. Moreover, the separation power between track and shower events allows for establishing very pure track samples, a crucial prerequisite for studying neutrino oscillations.

description: We present two new proofs of Simon Henry's result that the category of simplicial sets admits a constructive counterpart of the classical Kan-Quillen model structure. Our proofs are entirely self-contained and avoid complex combinatorial arguments on anodyne extensions. We also give new constructive proofs of the left and right properness of the model structure.

description: The Physics Inventory of Quantitative Literacy (PIQL), a reasoning inventory under development, aims to assess students' physics quantitative literacy at the introductory level. The PIQL's design presents the challenge of isolating types of mathematical reasoning that are independent of each other in physics questions. In its current form, the PIQL spans three principle reasoning subdomains previously identified in mathematics and physics education research: ratios and proportions, covariation, and signed (negative) quantities. An important psychometric objective is to test the orthogonality of these three reasoning subdomains. We present results from exploratory factor analysis, confirmatory factor analysis, and module analysis that inform interpretations of the underlying structure of the PIQL from a student viewpoint, emphasizing ways in which these results agree and disagree with expert categorization. In addition to informing the development of existing and new PIQL assessment items, these results are also providing exciting insights into students' quantitative reasoning at the introductory level.

description: The inter/intramolecular interactions and associations between constituents determine the microstructure of food and its response to mechanical deformation and flow. The characterization of food rheology enables the design of efficient processing equipment, production of high-quality, stable end products, prediction of textural and sensorial attributes, and assurance of consumer acceptability. Foods are subjected to rapid and large deformations during processing operations and consumption. Dynamic oscillatory shear tests are carried out by subjecting food to a sinusoidal deformation (or stress) and probing the mechanical stress (or strain) and recording the response as a function of time. In the SAOS region, the mechanical response is in the form of a perfect sinusoidal curve and interpretation is straightforward as expected from a linear model. On the other hand, LAOS response requires complex mathematical relations to extract meaningful rheological parameters. In this dissertation, Fourier Transform-Chebyshev Decomposition (FTC) and Sequence of Physical Processes (SPP) methods were utilized to quantify the LAOS response of selected food materials. The objective of this study is to gain new insights into the nonlinear rheology and structural architecture of food materials. To offer insights into the microstructure–rheology relations, rheological measurements were accompanied by various techniques probing chemical interactions (FTIR), imaging (Cryo-SEM, SEM), quantitative network analysis, and molecular size (SDS-PAGE). This dissertation showed that LAOS rheology is highly correlated with the network structure of food shown by the quantitative network analysis utilizing SEM images. It is a powerful tool to detect the effect of small molecules on the nonlinear rheology of food (HMW-LMW glutenin ratio, gliadin for dough, fat content in yogurt, and amylopectin/amylose ratio of starch in a suspension). Nonlinear parameters were sensitive to structural changes occurring in dough structure during processing conditions including aging at room and elevated temperatures. Lastly, the SPP method enabling time-resolved interpretation of nonlinear rheology provided detailed transient microstructural interpretations whereas the FTC method gave static measures at specific strains in an oscillation cycle. Thus, nonlinear rheology of doughs with various gluten subfractions in MAOS and LAOS regions as well as shear thickening characteristic of starch suspensions with changing amylopectin/amylose ratio interpreted by the SPP method gave more sensitive results than the FTC method. The application of fundamental knowledge from this work can be a guide to evaluating the architecture and nonlinear rheology of food for the assurance of consumer acceptancy and the fabrication of efficient machinery by building more accurate mechanical models of complex food systems.

description: Most Americans know that our national capital was captured by the British during the war of 1812, but how many realize that Washington was almost captured again during the Civil War? The stories of Bull Run, Antietam, and Gettysburg are familiar to us all, and have been widely discussed in books and periodicals. General Jubal A. Early's raid on Washington during the Civil War has not received attention comparable to its importance, however. Numerous accounts have discussed certain phases of Early's raid in detail, but none of them gives a complete picture of the raid from the time of its inception in the minds of the Confederate leaders to its ultimate failure at the very gates of Washington. I have attempted, in this thesis, to write a complete and accurate account of Early's raid, including many aspects which other writers have omitted.

description: Stereoscopic virtual reality (VR) has experienced a resurgence due to flagship products such as the Oculus Rift, HTC Vive and smartphone-based VR solutions like Google Cardboard. This is causing the question to resurface: how can stereoscopic VR be useful in instruction, if at all, and what are the pedagogical best practices for its use? To address this, and to continue our work in this sphere, we performed a study of 289 introductory physics students who were sorted into three different treatment types: stereoscopic virtual reality, WebGL simulation, and static 2D images, each designed to provide information about magnetic fields and forces. Students were assessed using preliminary items designed to focus on heavily-3D systems. We report on assessment reliability, and on student performance. Overall, we find that students who used VR did not significantly outperform students using other treatment types. There were significant differences between sexes, as other studies have noted. Dependence on students' self-reported 3D videogame play was observed, in keeping with previous studies, but this dependence was not restricted to the VR treatment.

title: Polens Erinnerungspolitik
Creators: name: Heckermann, Blanka
Year: 2017

description: Die Erfahrung mit dem Staatssozialismus prägt bis heute Polens Erinnerungspolitik. Verschiedene Geschichtsinterpretationen konkurrieren miteinander und dienen manchen Akteuren der politischen Instrumentalisierung sowie Legitimierung. Auch auf symbolischer Ebene lässt sich der Umgang mit der Vergangenheit erkennen. Diese Masterarbeit erläutert anhand der Gedenkreden zum Unabhängigkeitstag der Staatspräsidenten ab 1989 ob, wie und mit welchen Intentionen das Erbe des Staatssozialismus gedeutet und genutzt wird. Des Weiteren wird versucht diese Geschichtsdarstellungen in Vergleich der einzelnen Präsidenten zu stellen und Rückschlüsse daraus auf die polnische Erinnerungspolitik und ihrer Akteure zu ziehen. Ergänzend werden die innenpolitischen Debatten, vor allem nach 1989, beleuchtet. Den theoretischen Rahmen stellen Begriffe der Erinnerungs- bzw. Geschichtspolitik, der Erinnerungskultur, Polens Identität und Nationalbewusstsein sowie die Akteure der Geschichtspolitik und Gesellschaft im Bezug auf den Staatssozialismus in Polen dar.

description: Searching for geometric objects that are close in space is a fundamental component of many applications. The performance of search algorithms comes to the forefront as the size of a problem increases both in terms of total object count as well as in the total number of search queries performed. Scientific applications requiring modern leadership-class supercomputers also pose an additional requirement of performance portability, i.e. being able to efficiently utilize a variety of hardware architectures. In this paper, we introduce a new open-source C++ search library, ArborX, which we have designed for modern supercomputing architectures. We examine scalable search algorithms with a focus on performance, including a highly efficient parallel bounding volume hierarchy implementation, and propose a flexible interface making it easy to integrate with existing applications. We demonstrate the performance portability of ArborX on multi-core CPUs and GPUs, and compare it to the state-of-the-art libraries such as Boost.Geometry.Index and nanoflann.
