A Bear in the Desert: How Putin Justified the Russian Military Intervention in Syria
Creators: name: Takvorian, Charles
Publisher: name: My University
Year: 2022

description: This paper studies how the President of Russia, Vladimir Putin, justified the Russian intervention in the Syrian civil war and compares the arguments he used in the domestic and in the international contexts. Relying on discourse analysis, this research project systematically analyses 133 speeches made by the Russian President between 2011 and 2021. It identifies the main themes that emerge from these speeches and illustrates in three word clouds how Putin articulates his rationale depending on the audience. Among other things, this project finds that in a domestic context, Putin mainly framed the intervention as an anti-terrorist operation that prevented terrorists from coming to Russia. In parallel, when he spoke to an international audience, he emphasized the importance of international cooperation and the need to find a political solution to the Syrian crisis. This paper deconstructs these arguments that form Putin’s narrative and examines the underlying ideas and interests. It also links them to the broader international context which has been marked by increasing tensions between Russia and the West following Moscow’s annexation of Crimea. Overall, this Major Research Project contributes to the academic knowledge on how Putin uses narratives and ideas to justify military actions outside of Russia’s borders. Keywords: Russia, Putin, Syria, Middle East, intervention, justification, discourse, audience.

description: The origin of fast radio bursts (FRBs) remains mysterious. Recently, the only repeating FRB source, FRB 121102, was reported to possess an extremely large and variable rotation measure (RM). The inferred magnetic field strength in the burst environment is comparable to that in the vicinity of the super-massive black hole Sagittarius A* of our Galaxy. Here we show that all the observational properties of FRB 121102 (including the high RM and its evolution, the high linear polarization degree, an invariant polarization angle across each burst and other properties previously known) can be interpreted within the cosmic comb model invoking a regular neutron star whose magnetosphere is sporadically and marginally combed by a variable outflow from a nearby low-luminosity accreting super-massive black hole in the host galaxy. We propose three falsifiable predictions of the model and discuss other FRBs within the context of the cosmic comb model as well as the challenges encountered by other repeating FRB models in light of the new observations.

description: Class incremental learning (CIL) is a challenging setting of continual learning, which learns a series of tasks sequentially. Each task consists of a set of unique classes. The key feature of CIL is that no task identifier (or task-id) is provided at test time. Predicting the task-id for each test sample is a challenging problem. An emerging theory-guided approach (called TIL+OOD) is to train a task-specific model for each task in a shared network for all tasks based on a task-incremental learning (TIL) method to deal with catastrophic forgetting. The model for each task is an out-of-distribution (OOD) detector rather than a conventional classifier. The OOD detector can perform both within-task (in-distribution (IND)) class prediction and OOD detection. The OOD detection capability is the key to task-id prediction during inference. However, this paper argues that using a traditional OOD detector for task-id prediction is sub-optimal because additional information (e.g., the replay data and the learned tasks) available in CIL can be exploited to design a better and principled method for task-id prediction. We call the new method TPL (Task-id Prediction based on Likelihood Ratio). TPL markedly outperforms strong CIL baselines and has negligible catastrophic forgetting. The code of TPL is publicly available at https://github.com/linhaowei1/TPL.

Facilitar a través de la asociación, la construcción de obras de servicio y utilidad común, propicia la creación de riqueza, porque el ejercer la libertad de asociación, lleva a estrechar los vínculos de las personas naturales y jurídicas, fortalece la noción de región, hace efectiva la democracia económica y conduce eficazmente a la democracia política y social. Esta tesis, demuestra la urgente necesidad de la asociación y la evidente utilidad de la misma para mejorar el nivel de la población, es decir, de esa parte de la nación en la que, de acuerdo a la constitución de 1886, reside esencial y exclusivamente la soberanía, de donde emanan todos los poderes públicos. El Sr. Doctor Antonio Rocha Alvira tuvo la generosidad como su presidente de escribirle un prólogo que fue publicado en el magazín dominical del diario El Tiempo el 6 de marzo de 1983.

Facilitating, through association, the construction of works of service and common utility, promotes the creation of wealth, because exercising freedom of association leads to closer ties between natural and legal persons, strengthens the notion of region, makes effective economic democracy and leads effectively to political and social democracy. This thesis demonstrates the urgent need for the association and its obvious usefulness to improve the level of the population, that is, of that part of the nation in which, according to the constitution of 1886, resides essentially and exclusively sovereignty, from which all public powers emanate.

description: In the interest of designing a recursive module extension to ML that is as simple and general as possible, we propose a novel type system for general recursion over effectful expressions. The presence of effects seems to necessitate a backpatching semantics for recursion based on Scheme's. Our type system ensures statically that recursion is well-founded (that the body of a recursive expression will evaluate without attempting to access the undefined recursive variable), which avoids some unnecessary run-time costs associated with backpatching. To ensure well-founded recursion in the presence of multiple recursive variables and separate compilation, we track the usage of individual recursive variables, represented statically by "names". So that our type system may eventually be integrated smoothly into ML's, reasoning involving names is only required inside code that uses our recursive construct and does not need to infect existing ML code.

description: Many areas of the world are without basic information on the socioeconomic well-being of the residing population due to limitations in existing data collection methods. Overhead images obtained remotely, such as from satellite or aircraft, can help serve as windows into the state of life on the ground and help "fill in the gaps" where community information is sparse, with estimates at smaller geographic scales requiring higher resolution sensors. Concurrent with improved sensor resolutions, recent advancements in machine learning and computer vision have made it possible to quickly extract features from and detect patterns in image data, in the process correlating these features with other information. In this work, we explore how well two approaches, a supervised convolutional neural network and semi-supervised clustering based on bag-of-visual-words, estimate population density, median household income, and educational attainment of individual neighborhoods from publicly available high-resolution imagery of cities throughout the United States. Results and analyses indicate that features extracted from the imagery can accurately estimate the density (R$^2$ up to 0.81) of neighborhoods, with the supervised approach able to explain about half the variation in a population's income and education. In addition to the presented approaches serving as a basis for further geographic generalization, the novel semi-supervised approach provides a foundation for future work seeking to estimate fine-scale information from aerial imagery without the need for label data.

description: For a ring $R$, Hilbert's Tenth Problem $HTP(R)$ is the set of polynomial equations over $R$, in several variables, with solutions in $R$. We view $HTP$ as an operator, mapping each set $W$ of prime numbers to $HTP(\mathbb Z[W^{-1}])$, which is naturally viewed as a set of polynomials in $\mathbb Z[X_1,X_2,\ldots]$. For $W=\emptyset$, it is a famous result of Matiyasevich, Davis, Putnam, and Robinson that the jump $\emptyset~\!'$ is Turing-equivalent to $HTP(\mathbb Z)$. More generally, $HTP(\mathbb Z[W^{-1}])$ is always Turing-reducible to $W'$, but not necessarily equivalent. We show here that the situation with $W=\emptyset$ is anomalous: for almost all $W$, the jump $W'$ is not diophantine in $\mathbb Z[W^{-1}]$. We also show that the $HTP$ operator does not preserve Turing equivalence: even for complementary sets $U$ and $\overline{U}$, $HTP(\mathbb Z[U^{-1}])$ and $HTP(\mathbb Z[\overline{U}^{-1}])$ can differ by a full jump. Strikingly, reversals are also possible, with $V

description: We present a type theory for higher-order modules that accounts for many central issues in module system design, including translucency, applicativity, generativity, and modules as first-class values. Our type system harmonizes design elements from previous work, resulting in a simple, economical account of modular programming. The main unifying principle is the treatment of abstraction mechanisms as computational effects. Our language is the first to provide a complete and practical formalization of all of these critical issues in module system design.
Schengen Still Standing: Internal Borders, Integration, and COVID-19
Creators: name: Lojk, Ryan
Publisher: name: My University
Year: 2022

description: In early 2020, widespread reintroductions of internal border controls were taken by member states across the Schengen Area in response to the COVID-19 pandemic. This had perilous consequences for the European economy, which was nearly ground to a halt by these restrictions. This paper investigates the impacts this crisis has had on integration with regards to Schengen. It argues that this crisis has driven member states to deepen integration, as the economic benefits of Schengen are too important to abandon. This paper also highlights how ad hoc improvisation was essential to ensuring that the Schengen Area was able to get back on its feet during this crisis. These crisis proven improvised measures have since been adopted into ongoing reforms to Schengen governance, which seeks to build an agreement better equipped to handle future challenges.

title: Fabrication of methylammonium lead iodide thin ﬁlms via sequential closed space sublimation
Creators: name: Dachauer, Ralph
Publisher: name: UNSPECIFIED
Year: 2019

description: In this work, the characterization of methylammonium lead iodide (MAPI) layers, which were fabricated from PbI2 and PbCl2 via a sequential (2step) closed space sublimation (CSS) route under high vacuum, is presented. The characterization was carried out by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), UV/VIS absorption spectroscopy, photoluminescence (PL) spectroscopy and in vacuo photoelectron spectroscopy (PES). In addition, the 2step CSS MAPI layers were incorporated into planar solar cells and which were subsequently analyzed. For the transformation of the lead salt layers in the CSS, four substrate temperatures (75 °C, 90 °C, 130 °C, 150 °C) were chosen. The crucible temperatures and transformation times were adjusted to obtain most complete transformations. A high phase purity for the 2step CSS MAPI fabricated from PbI2 and from PbCl2 can be derived from the XRD measurements in the whole substrate temperature range. The SEM measurements show that the morphology of the MAPI layers undergoes signiﬁcant changes which become more pronounced with increasing substrate temperature and can be separated into three distinct processes taking place simultaneously: the formation of the perovskite by incorporation of MAI into the lead salt grains, the recrystallization of the perovskite grains and an Ostwald ripening like growth of the recrystallized grains. From UV/VIS spectroscopy experiments a band gap of MAPI around 1.58 eV could be derived. The in vacuo PES experiments show the Fermi level pinned to the conduction band minimum. The UV/VIS and PE spectroscopy results appear to be independent on the substrate temperature. Combining the UV/VIS and the PES results, band energy diagrams for PbI2, PbCl2, MAI and MAPI could be created. Those band energy diagrams highlight the importance of a complete reaction of the lead salt on one hand and the avoidance of a MAI capping layer on top of the MAPI absorber, on the other hand. Working solar cells incorporating MAPI layers derived form PbI2 and from PbCl2 could be fabricated for all examined substrate temperatures. However, the efﬁciencies of the fabricated solar cells were mostly limited to the range of 2-3 %, with few solar cells exceeding 4 %. The reason for this is probably the combination of a hindered charge extraction due to a thin PbI2 interface layer between the MAPI absorber and the FTO/TiO2 electrode with the recombination of photoexcited charge carriers in the MAPI layers. Nevertheless, the relatively large size and the narrow efﬁciency distribution of the solar cells on one substrate indicate the potential of the 2step CSS process to fabricate solar cells with active areas in the square centimeter regime. Thereby, the unique property of the CSS, the combination of high processing temperatures and a high vacuum environment, is expected to open promising opportunities, especially for research on inorganic perovskite absorber materials.

description: We study the electronic waiting time distributions (WTDs) in a non-interacting quantum dot spin valve by varying spin polarization and the noncollinear angle between the magnetizations of the leads using scattering matrix approach. Since the quantum dot spin valve involves two channels (spin up and down) in both the incoming and outgoing channels, we study three different kinds of WTDs, which are two-channel WTD, spin-resolved single-channel WTD and cross-channel WTD. We analyze the behaviors of WTDs in short times, correlated with the current behaviors for different spin polarizations and noncollinear angles. Cross-channel WTD reflects the correlation between two spin channels and can be used to characterize the spin transfer torque process. We study the influence of the earlier detection on the subsequent detection from the perspective of cross-channel WTD, and define the influence degree quantity as the cumulative absolute difference between cross-channel WTDs and first passage time distributions to quantitatively characterize the spin flip process. The influence degree shows a similar behavior with spin transfer torque and can be a new pathway to characterize spin correlation in spintronics system.

description: Research Questions: We explored if and how decision-makers of different types of national sport organizations (NSOs) govern their brand, considering the changing landscape and the role of stakeholders and social media. The three research questions were: (RQ1) Do leaders of NSOs include brand governance in their overall governance?; (RQ2) How important is the relationship between the NSOs and their stakeholders for NSOs’ brand governance?; (RQ3) How does social media contribute to NSOs’ brand governance? Research methods: Thirty-two chief executive officers (CEOs) and/or board members of 58 Canadian NSOs (RR=55%) participated in an online survey. Data were collected about brand governance in the organization (8 questions), the interrelationship with stakeholders (4 questions), and the role of social media in brand governance (4 questions). Results and findings: Brand governance is absent in small NSOs, and in early stages of application by larger NSOs. NSOs deal with their brand primarily internally, with no operational involvement of stakeholders, missing opportunities for possible knowledge transfer and co-creation to help NSOs govern their brand. Social media is a cost-efficient way to brand the organization, but a lack of control and consistency indicates a need for brand governance related to social media. Implications: NSOs would benefit from actively involving stakeholders to co-create and strengthen their brand. Social media offers opportunities for branding, but governance regulations should help overcome major challenges. Future research should include 3 interviews with NSOs’ decision-makers to further understand how NSOs can engage more meaningfully with stakeholders and social media to strengthen their brand governance.
On the foundation of equipartition in supernova remnants

description: A widely accepted paradigm is that equipartition (eqp) between the energy density of cosmic rays (CRs) and the energy density of the magnetic field cannot be sustained in supernova remnants (SNRs). However, our 3D hydrodynamic supercomputer simulations, coupled with a non-linear diffusive shock acceleration model (NLDSA), provide evidence that eqp may be established at the end of the Sedov phase of evolution in which most SNRs spend the longest portions of their lives. We introduce term "constant partition" for any constant ratio between the CR energy density and the energy density of magnetic field in an SNR, while term "equipartition" should be reserved for the case of approximately the same values of the energy density (also, it is {constant partition} in the order of magnitude) of ultrarelativistic electrons only (or CRs in total) and the energy density of magnetic field. Our simulations suggest that this approximate constant partition does exist in all but the youngest SNRs. We speculate that since evolved SNRs at the end of the Sedov phase of evolution can reach eqp between CRs and magnetic fields, they may be responsible for initializing this type of eqp in the interstellar medium. Additionally, we show that eqp between the electron component of CRs and magnetic field may be used for calculating the magnetic field strength directly from observations of synchrotron emission from SNRs. The values of magnetic field strengths in SNRs given here are approximately 2.5 times lower than values calculated by Arbutina et al. (2012, 2013).

description: Quantum Neural Networks (QNNs) are suggested as one of the quantum algorithms which can be efficiently simulated with a low depth on near-term quantum hardware in the presence of noises. However, their performance highly relies on choosing the most suitable architecture of Variational Quantum Algorithms (VQAs), and the problem-agnostic models often suffer issues regarding trainability and generalization power. As a solution, the most recent works explore Geometric Quantum Machine Learning (GQML) using QNNs equivariant with respect to the underlying symmetry of the dataset. GQML adds an inductive bias to the model by incorporating the prior knowledge on the given dataset and leads to enhancing the optimization performance while constraining the search space. This work proposes equivariant Quantum Convolutional Neural Networks (EquivQCNNs) for image classification under planar $p4m$ symmetry, including reflectional and $90^\circ$ rotational symmetry. We present the results tested in different use cases, such as phase detection of the 2D Ising model and classification of the extended MNIST dataset, and compare them with those obtained with the non-equivariant model, proving that the equivariance fosters better generalization of the model.

Das heißt, die fertigungstechnische Ausbildung ist sehr praxisorientiert. In der industriellen Fertigung, in der viele an Hochschulen für angewandte Wissenschaften ausgebildete Ingenieure arbeiten, herrscht oft großer Termindruck. Dadurch bleibt dem Ingenieur wenig Zeit für Recherche, Dokumentation und Nachbereitung von Projekten. Aufgabe der Fort- und Weiterbildung ist es, dem Praktiker die Möglichkeiten der Digitalisierung für die tägliche wissensbasierte Arbeit aufzuzeigen und Kompetenzen zum effizienten Umgang zu vermitteln. Beispielsweise werden durch den Einsatz von virtuellen Maschinen Prozesse effizienter, wenn Versuche eingespart werden können. Mit digitalen Werkzeugen lässt sich weiterhin die Lehre, Fort- und Weiterbildung optimieren, indem beispielsweise ein weltweiter Zugriff auf Lehrlizenzen gewährt wird oder die Zusammenarbeit über Lernplattformen gefördert wird.
Man Machine Poem: Viewing the Tragically Hip's final tour through a post-humanitarianism lens
Creators: name: Vreugdenhil;Beauclerc, Connor
Publisher: name: My University
Year: 2018

description: In late 2015, Gord Downie, lead singer of the iconic Canadian rock band the Tragically Hip was diagnosed with glioblastoma, a terminal brain cancer. Some eight months later, on August 20, 2016, the band completed its final concert tour in its hometown of Kingston, Ontario. One of the many noteworthy features of the tour was the extensive fan-based fundraising efforts for brain cancer research that accompanied it. In recent years, some commentators have characterized this type of emotional outpouring as a form of ethical ambivalence or post-humanitarianism reflecting a sensibility of pity that valorizes a consumerist oriented form of short-term low-intensity agency as opposed to some more authentic forms of empathy. A leading figure in developing the concept of post-humanitarianism is Lilie Chouliaraki. Her 2013 book, The Ironic Spectator, investigates four different aspects of contemporary humanitarian communication appeals, celebrity, concerts, and news to examine the ethical ambivalence underlying post-humanitarianism. Drawing on Chouliaraki’s claims about the influence of celebrity and news reporting in fostering post-humanitarianism, this Major Research Paper analyzes newspaper reporting of the Hip’s Man Machine Poem tour in order to assess how news reporting of celebrity and suffering is structured when the celebrity is the suffering other.

description: Abstract: "Many heuristics have been developed for adapting on-disk data layouts to expected and observed workload characteristics. This paper describes a two-tiered software architecture for cleanly and extensibly combining such heuristics. In this architecture, each heuristic is implemented independently and an adaptive combiner merges their suggestions based on how well they work in the given environment. The result is a simpler and more robust system for automated tuning of disk layouts, and a useful blueprint for other complex tuning problems such as cache management, scheduling, data migration, and so forth."

The result can be used to extend the concept of path-ordering, as employed in the Wilson loop, from a closed curve into the interior of a surface spanning the curve. Taking this surface as a string world-sheet yields a generalisation of the string contact interaction previously used to represent the Abelian Wilson loop as a tensionless string. We also describe a supersymmetric generalisation.

description: The ordinary contact process is used to model the spread of a disease in a population. In this model, each infected individual waits an exponentially distributed time with parameter 1 before becoming healthy. In this paper, we introduce and study the contact process in a randomly evolving environment. Here we associate to every individual an independent two-state, $\{0,1\},$ background process. Given $δ_0

description: Inspired by the recent work by Delacretaz et. al., we rigorously derive an exact and simple method to bosonize a non-interacting fermionic system with a Fermi surface starting from a microscopic Hamiltonian. In the long-wavelength limit, we show that the derived bosonized action is exactly equivalent to the action obtained by Delacretaz et. al. In addition, we propose diagrammatic rules to evaluate correlation functions using our bosonized theory and demonstrate these rules by calculating the three- and four-point density correlation functions. We also consider a general density-density interaction and show that the simplest approximation in our bosonic theory is identical to RPA results.

description: Dimensions are an integral part of many models we use every day. Without thinking about it, we frequently use the time dimension: many financial and accounting spreadsheets have columns representing months or years. Representing a second dimension is often done by repeating blocs of formulas in a worksheet or creating multiple worksheets with the same structure.

Gender Wage Differential in Canada, 2000-2018
Creators: name: Ahmed, Nabia
Publisher: name: My University
Year: 2020

description: The main purpose of this research is to update the Canadian evidence on the gender wage gap and see if the results have changed since the Great Recession of 2008. Using public-use files of the 2018 National Graduates Survey, I find that the gender wage gap ten years after the Great Recession is essentially the same as it was in the years prior to this recession. Furthermore, employing a Blinder-Oaxaca decomposition, I find that mean characteristics have little explanatory power, other than industry. Industry is the greatest contributor in explaining the gender wage gap. However, the largest portion of the gender wage gap still remains unexplained.

description: El objetivo del presente estudio de caso fue analizar los principios expuestos en el Acuerdo de la Facilitación del comercio en comparación con la realidad del Acuerdo de la Facilitación del comercio en Colombia. Para lograr dicho objetivo se realizó inicialmente, un análisis de la literatura y de la normatividad actual, con el propósito de identifica a fecha de hoy si se cumple o no con lo que se propone dentro de la documentación. En cuanto a la metodología, se contó con dos expertos de empresas privadas quienes, desde su cargo como gerentes de operaciones, informaron que algunos de los principios no se cumplen y que el proceso de la implementación ha sido bastante complicado. Como resultado se logro identificar que actualmente en Colombia, los principios se están llevando a cabo, no obstante, la implementación ha sido un poco difícil, pues la transparencia, la simplificación la armonización y la estandarización no se identifican tan claramente en la parte operativa.
description: The objective of this case study was to analyze the principles set forth in the Trade Facilitation Agreement in comparison with the reality of the Trade Facilitation Agreement in Colombia. To achieve this objective, an analysis of the literature and current regulations was initially carried out, with the purpose of identifying a date of today if what is proposed within the documentation is fulfilled or not. Regarding the methodology, there were two experts from private companies who from their position as operations managers, information that some of the principles are not met and that the implementation process has been quite complicated. As a result, it is possible to identify that currently in Colombia, the principles are being carried out, however, the implementation has been a bit difficult, since transparency, simplification, harmonization and standardization are not so clearly identified in the operational part.

description: Let $(ξ_i,\mathcal{F}_i)_{i\geq1}$ be a sequence of martingale differences. Set $S_n=\sum_{i=1}^nξ_i $ and $[ S]_n=\sum_{i=1}^n ξ_i^2.$ We prove a Cramér type moderate deviation expansion for $\mathbf{P}(S_n/\sqrt{[ S]_n} \geq x)$ as $n\to+\infty.$ Our results partly extend the earlier work of [Jing, Shao and Wang, 2003] for independent random variables.

description: To search for low-redshift damped Lyα (DLA) and sub-DLA quasar absorbers, we have conducted a 21 cm absorption survey of radio-loud quasars at small impact parameters to foreground galaxies selected from the Sloan Digital Sky Survey (SDSS). Here we present the first results from this survey based on observations of SDSS J104257.58+074850.5 (z QSO = 2.66521), a quasar at an angular separation from a foreground galaxy (z gal = 0.03321) of 25 (1.7 kpc in projection). The foreground galaxy is a low-luminosity spiral with on-going star formation (0.004 M yr–1 kpc–2) and a metallicity of –0.27 ± 0.05 dex. We detect 21 cm absorption from the galaxy with the Green Bank Telescope (GBT), the Very Large Array (VLA), and the Very Long Baseline Array (VLBA). The absorption appears to be quiescent disk gas co-rotating with the galaxy and we do not find any evidence for outflowing cold neutral gas. The width of the main absorption line indicates that the gas is cold, Tk < 283 K, and the H I column is surprisingly low given the impact parameter of 1.7 kpc; we find that N(H I) ≤9.6 × 1019 cm–2 (GBT) and N(H I) ≤1.5 × 1020 cm–2 (VLBA). VLBA marginally resolves the continuum source and the absorber, and a lower limit of 27.1 × 13.9 pc is derived for the size of the absorbing cloud. In turn, this indicates a low density for a cold cloud, n(H I) < 3.5 cm–3. We hypothesize that this galaxy, which is relatively isolated, is becoming depleted in H I because it is converting its interstellar matter into stars without a replenishing source of gas, and we suggest future observations to probe this and similar galaxies.
A Trainable Transfer-based Machine Translation Approach for Languages with Limited Resources

description: We describe a Machine Translation (MT) approach that is specifically designed to enable rapid development of MT for languages with limited amounts of online resources. Our approach assumes the availability of a small number of bi-lingual speakers of the two languages, but these need not be linguistic experts. The bi-lingual speakers create a comparatively small corpus of word aligned phrases and sentences (on the order of magnitude of a few thousand sentence pairs) using a specially designed elicitation tool. From this data, the learning module of our system automatically infers hierarchical syntactic transfer rules, which encode how syntactic constituent structures in the source language transfer to the target language. The collection of transfer rules is then used in our run-time system to translate previously unseen source language text into the target language. We describe the general principles underlying our approach, and present results from an experiment, where we developed a basic Hindi-to-English MT system over the course of two months, using extremely limited resources.
