Nestorian Christianity
Creators: name: Koralija, Srecko

description: Nestorian Christianity as a distinguished Christian group came into existence after the Christological movement that held the theological position initially developed by Nestorius (4/5 CE). Nestorius considered Christ the Son of God and Christ the son of Mary as two separate persons with two natures rather than one person having human and divine nature. That Christological teaching was officially condemned by the Council of Ephesus in 431. The Council of Ephesus anathema led to the separation of the early Church, development of the Nestorian doctrine and ultimately initiated the process of creating the so-called Church of the East. The teaching of the Church of the East as it developed throughout history should be distinguished from the initial Nestorian teaching. Theological differences quickly had political and socio-cultural implications at the global level (relationship with the Western Church as well as other Christian communities in the East). Historically speaking, Nestorian Christians played an important role in bringing Christianity to China as well as other regions like Mongolia and India. The historical timeline of Nestorian Christianity depends on the region, socio-cultural setting and date of missionary penetration. The bilingual (Chinese-Syriac) Nestorian stele (8th ct) from Xian witnesses to the early 7th century presence of Christians in the area. Nestorian Christians also reached India, and interacted with many other groups as Mongols, Turks, and Uigurs. Members of the Nestorian community played an important role during the Islamic period when they translated many works by Aristotle into Arabic (e.g. Timothy I). Modern Assyrian Church of the East is the successor of medieval Nestorian Christians, but its doctrine today should not be identified with Nestorius. After the disintegration of the Mongolian Empire during the 14th century, the Church of the East faced rapid decline. In the aftermath of these events, the presence of Nestorian Christianity was mainly reduced to India and Mesopotamia. During the 16th century, some members of the community united with the Roman Catholic Church and were named Chaldeans, whereas those who did not united with the RCC became known as Assyrians. Nestorian Christians faced persecutions in Persia during the 6th century, but flourished in China (7-10th ct), and was also well received during the medieval Mongolian period.

subject: evasive malware
subject: multi-execution

description: Malware is a foundational component of cyber crime that enables an attacker to modify the normal operation of a computer or access sensitive, digital information. Despite the extensive research performed to identify such programs, existing schemes fail to detect evasive malware, an increasingly popular class of malware that can alter its behavior at run-time, making it difficult to detect using today’s state of the art malware analysis systems. In this thesis, we present DVasion, a comprehensive strategy that exposes such evasive behavior through a multi-execution technique. DVasion successfully detects behavior that would have been missed by traditional, single-execution approaches, while addressing the limitations of previously proposed multi-execution systems. We demonstrate the accuracy of our system through strong parallels with existing work on evasive malware, as well as uncover the hidden behavior within 167 of 1,000 samples.

description: Denitrification is a microbially-mediated process that converts nitrate (NO3-) to dinitrogen (N2) gas and has implications for soil fertility, climate change, and water quality. Using PCR, qPCR, and T-RFLP, the effects of environmental drivers and land management on the abundance and composition of functional genes were investigated. Environmental variables affecting gene abundance were soil type, soil depth, nitrogen concentrations, soil moisture, and pH, although each gene was unique in its spatial distribution and controlling factors. The inclusion of microbial variables, specifically genotype and gene abundance, improved denitrification models and highlights the benefit of including microbial data in modeling denitrification. Along with some evidence of niche selection, I show that nirS is a good predictor of denitrification enzyme activity (DEA) and N2O:N2 ratio, especially in alkaline and wetland soils. nirK was correlated to N2O production and became a stronger predictor of DEA in acidic soils, indicating that nirK and nirS are not ecologically redundant.

description: Current trends in speech-language pathology focus on early intervention as the preferred tool for promoting the best possible outcomes in children with language disorders. Neuroimaging techniques are being studied as promising tools for flagging at-risk infants. In this study, the auditory brainstem response (ABR) to the syllables /ba/ and /ga/ was examined in 41 infants between 3 and 12 months of age as a possible tool to predict language development in toddlerhood. The MacArthur-Bates Communicative Development Inventory (MCDI) was used to assess language development at 18 months of age. The current study compared the periodicity of the responses to the stop consonants and phase differences between /ba/ and /ga/ in both at-risk and low-risk groups. The study also examined whether there are correlations among ABR measures (periodicity and phase differentiation) and language development. The study found that these measures predict language development at 18 months.

description: I seek to create a Lucretius text useful for a high school classroom including a commentary on four sections of the poem.  The passages include 2.998 – 1047 which explains how the Epicurean atomic theory, 3.912—979 the famous passage that denies the underworld and its tortures, 5.855 – 923 the semi-Darwinian passage detailing the sorts of creatures that can exist in this world, and 5.1194– 1240 about the detrimental effects of humans fearing gods.

In addition to writing a commentary on these passages, I will explore the perception of Lucretius though the present day, in hopes of discovering how and why this important and influential  author has been so systematically excluded from secondary latin literary studies.  My discussion will include an overview of how modern Latin textbooks do or do not mention Lucretius and how his presence in these textbooks compares to his role in university-level Latin course offerings.

description: Background: Antivirals are needed to combat the COVID-19 pandemic, which is caused by SARS-CoV-2. The clinically-proven protease inhibitor Camostat mesylate inhibits SARS-CoV-2 infection by blocking the virus-activating host cell protease TMPRSS2. However, antiviral activity of Camostat mesylate metabolites and potential viral resistance have not been analyzed. Moreover, antiviral activity of Camostat mesylate in human lung tissue remains to be demonstrated. Methods: We used recombinant TMPRSS2, reporter particles bearing the spike protein of SARS-CoV-2 or authentic SARS-CoV-2 to assess inhibition of TMPRSS2 and viral entry, respectively, by Camostat mesylate and its metabolite GBPA. Findings: We show that several TMPRSS2-related proteases activate SARS-CoV-2 and that two, TMPRSS11D and TMPRSS13, are robustly expressed in the upper respiratory tract. However, entry mediated by these proteases was blocked by Camostat mesylate. The Camostat metabolite GBPA inhibited recombinant TMPRSS2 with reduced efficiency as compared to Camostat mesylate. In contrast, both inhibitors exhibited similar antiviral activity and this correlated with the rapid conversion of Camostat mesylate into GBPA in the presence of serum. Finally, Camostat mesylate and GBPA blocked SARS-CoV-2 spread in human lung tissue ex vivo and the related protease inhibitor Nafamostat mesylate exerted augmented antiviral activity. Interpretation: Our results suggest that SARS-CoV-2 can use TMPRSS2 and closely related proteases for spread in the upper respiratory tract and that spread in the human lung can be blocked by Camostat mesylate and its metabolite GBPA.
Unitarian Universalism

description: In the United States, the American Unitarian Association and Universalist Church of America merged in 1961 to form the Unitarian Universalist Association. Although Unitarians and Universalists were nominally Christian denominations, the Unitarian Universalists subsequently adopted the principles of free faith, in which each member unites in seeking truth and affirms each other's worth without the guidance of a particular doctrine or divinity. Now described as a liberal religious movement or post-Christian, Unitarian Universalists hold many different theological opinions and operate as a radically non-creedal body. There is a wide diversity of congregational structures and organizations and each group may self-describe as a church, society, fellowship, or temple, among other identifiers. Each Unitarian Universalist congregation is distinct in tone and content of worship, even within the same city, but each is guided by the seven Principles and six Sources. The Principles serve as a uniting guide and affirm the inherent worth and dignity of every person; justice, equity, and compassion in human relations; acceptance of one another and encouragement to spiritual growth; a free and responsible search for truth and meaning; the right of conscience and the use of the democratic process without congregations and in society at large; the goal of world community with peace, liberty and justice for all; and respect for the interdependent web of all existence of which we are part. The Sources include direct experience, words and deeds of prophetic people, wisdom from the world’s religions, Jewish and Christian teachings to love our neighbors, humanist teachings and the guidance of reason and science, and spiritual teachings drawn from Earth-centered traditions. As a result, congregants draw from religious traditions such as Christianity or Judaism; spiritual practices of meditation, yoga, and connection to nature; and other influences including Paganism and New Age beliefs. Unitarian Universalists express strong commitment to social justice and action. They contend that spirituality and community extend beyond the walls of the congregation and must be lived in the world, and this message has spread beyond the borders of North America. The International Council of Unitarians and Universalists provides a network of organizations worldwide, including congregations throughout Africa; Europe and the UK; Australia and New Zealand; India, the Philippines, Hong Kong, and Indonesia; the Caribbean; and in Central and South America. However, the tradition remains deeply affiliated with the West, as estimates indicate over 60% of Unitarian Universalists are in the United States and approximately 30% in Europe.

description: We consider a disordered Hubbard model and show that, at sufficiently weak disorder, a single spin-down mobile impurity can thermalize an extensive initially localized system of spin-up particles. Thermalization is enabled by resonant processes that involve correlated hops of the impurity and localized particles. This effect indicates that Anderson localized insulators behave as “supercooled” systems, with mobile impurities acting as ergodic seeds. We provide analytical estimates, supported by numerical exact diagonalization, showing how the critical disorder strength for such mechanism depends on the particle density of the localized system. In the U→∞ limit, doublons are stable excitations, and they can thermalize mesoscopic systems by a similar mechanism. The emergence of an additional conservation law leads to an eventual localization of doublons. Our predictions apply to fermionic and bosonic systems and are readily accessible in ongoing experiments simulating synthetic quantum lattices with tunable disorder.

description: The input of almost every machine learning algorithm targeting the properties of matter at the atomic scale involves a transformation of the list of Cartesian atomic coordinates into a more symmetric representation. Many of the most popular representations can be seen as an expansion of the symmetrized correlations of the atom density and differ mainly by the choice of basis. Considerable effort has been dedicated to the optimization of the basis set, typically driven by heuristic considerations on the behavior of the regression target. Here, we take a different, unsupervised viewpoint, aiming to determine the basis that encodes in the most compact way possible the structural information that is relevant for the dataset at hand. For each training dataset and number of basis functions, one can build a unique basis that is optimal in this sense and can be computed at no additional cost with respect to the primitive basis by approximating it with splines. We demonstrate that this construction yields representations that are accurate and computationally efficient, particularly when working with representations that correspond to high-body order correlations. We present examples that involve both molecular and condensed-phase machine-learning models.

description: Twin-screw extrusion is used to compound fillers into a polymer matrix in order to improve the properties of the final product. The resultant properties of the composite are determined by the operating conditions used during extrusion processing. Changes in the operating conditions affect the physics of the melt flow, inducing unique composite properties. In the following work, the Residence Stress Distribution methodology has been applied to model both the stress behavior and the property response of a twin-screw compounding process as a function of the operating conditions. The compounding of a pigment into a polymer melt has been investigated to determine the effect of stress on the degree of mixing, which will affect the properties of the composite. In addition, the pharmaceutical properties resulting from the compounding of an active pharmaceutical ingredient are modeled as a function of the operating conditions, indicating the physical behavior inducing the property responses.

description: Physically motivated and mathematically robust atom-centered representations of molecular structures are key to the success of modern atomistic machine learning. They lie at the foundation of a wide range of methods to predict the properties of both materials and molecules and to explore and visualize their chemical structures and compositions. Recently, it has become clear that many of the most effective representations share a fundamental formal connection. They can all be expressed as a discretization of n-body correlation functions of the local atom density, suggesting the opportunity of standardizing and, more importantly, optimizing their evaluation. We present an implementation, named librascal, whose modular design lends itself both to developing refinements to the density-based formalism and to rapid prototyping for new developments of rotationally equivariant atomistic representations. As an example, we discuss smooth overlap of atomic position (SOAP) features, perhaps the most widely used member of this family of representations, to show how the expansion of the local density can be optimized for any choice of radial basis sets. We discuss the representation in the context of a kernel ridge regression model, commonly used with SOAP features, and analyze how the computational effort scales for each of the individual steps of the calculation. By applying data reduction techniques in feature space, we show how to reduce the total computational cost by a factor of up to 4 without affecting the model’s symmetry properties and without significantly impacting its accuracy.

description: Charge carrier lifetime measurements in bulk or unfinished photovoltaic (PV) materials allow for a more accurate estimate of power conversion efficiency in completed solar cells. In this work, carrier lifetimes in PV- grade silicon wafers are obtained by way of quasi-steady state photoconductance measurements. These measurements use a contactless RF system coupled with varying narrow spectrum input LEDs, ranging in wavelength from 460 nm to 1030 nm. Spectral dependent lifetime measurements allow for determination of bulk and surface properties of the material, including the intrinsic bulk lifetime and the surface recombination velocity. The effective lifetimes are fit to an analytical physics-based model to determine the desired parameters. Passivated and non-passivated samples are both studied and are shown to have good agreement with the theoretical model.

description: The interaction of a magnetic insulator with the helical electronic edge of a two-dimensional topological insulator has been shown to lead to many interesting phenomena. One of these is that for a suitable orientation of the magnetic anisotropy axis, the exchange coupling to an easy-plane magnet has no effect on DC electrical transport through a helical edge, despite the fact that it opens a gap in the spectrum of the helical edge [Meng et al., Phys. Rev. B 90, 205403 (2014)]. Here, we theoretically consider such a magnet embedded in an interferometer, consisting of a pair of helical edge states connected by two tunneling contacts, at which electrons can tunnel between the two edges. Using a scattering matrix approach, we show that the presence of the magnet in one of the interferometer arms gives rise to AC currents in response to an applied DC voltage. On the other hand, the DC Aharonov-Bohm effect is absent at zero temperature and small DC voltages, and only appears if the applied voltage or the temperature exceeds the magnet-induced excitation gap.

description: Liquid crystals (LCs) have revolutionized the display and communication technologies. Doping of LCs with inorganic nanoparticles such as carbon nanotubes, gold nanoparticles and ferroelectric nanoparticles have garnered the interest of research community as they aid in improving the electro-optic performance. In this thesis, we examine a hybrid nanocomposite comprising of 5CB liquid crystal and block copolymer functionalized barium titanate ferroelectric nanoparticles. This hybrid system exhibits a giant soft-memory effect. Here, spontaneous polarization of ferroelectric nanoparticles couples synergistically with the radially aligned BCP chains to create nanoscopic domains that can be rotated electromechanically and locked in space even after the removal of the applied electric field. The resulting non-volatile memory is several times larger than the non-functionalized sample and provides an insight into the role of non-covalent polymer functionalization. We also present the latest results from the dielectric and spectroscopic study of field assisted alignment of gold nanorods.

Nigerian Pentecostalism

Publisher: name: Database of Religious History (DRH)
Year: 2020

description: Pentecostalism has become a major cultural force in Nigeria since the early twentieth century, accounting for approx. 63% of Nigerian Christians today (World Christian Database). The success of Pentecostalism across Nigeria and Africa more widely has resulted in the widespread absorption of Pentecostal styles of worship into 'mainstream' African Protestant and Catholic churches (the latter known as 'Charismatic' churches). Pentecostals emphasise the active presence of the Holy Spirit both in worship settings and beyond, evidenced in miracles, healings, prophecies, tongues (glossolalia) and other 'gifts of the Spirit'. Nigerian Pentecostals tend to regard their religious faith as a means by which to ‘break’ with their ‘pagan’ heritage, and becoming born again as a way to be delivered from indigenous African spiritual and cultural life (Meyer 1998). Some Pentecostal churches place a strong emphasis on tithing and material success (‘Prosperity’), whilst others are more focused on asceticism and purity ('Holiness'), or healing and exorcism (‘Deliverance’). Pentecostalism in Nigeria is widely recognised to have unfolded in three phases. The first phase, known as Aladura, or the African Initiated/Independent Church movement, (1910-1930s) was led by Yoruba itinerant preachers like Joseph Ayo Babalola who clashed with missionaries on the use of medicine (Peel 1968). The Aladura movement, meaning ‘praying people’, emphasised prayer, healing and deliverance from traditional 'pagan' religion. In this period, foreign Pentecostal denominations like the Classical Pentecostal church, Assemblies of God, and the Welsh Apostolic church also laid down roots in Nigeria. The second wave, known as the 'Latter Rain' revival, took place in the 1950s and was initiated by British and American evangelists like Sydney Granville Elton and Oral Roberts. This phase emphasised deliverance, healing and also apocalyptic eschatology. The third wave, known as the Neo-Pentecostal movement, emerged in the 1960s-80s and was heavily influenced by ideas and trends introduced to Nigeria in American evangelical literature. Open air revivals, especially on university campuses such as the Universities of Ibadan and Ife, led to an influx of young converts to the movement. Some denominations emphasised Holiness and millennialism (1970s) whilst others propagated the Prosperity Gospel (80s onward). This period saw the emergence of the Nigerian Pentecostal megachurches like Deeper Life Bible Church and the Church of God Mission International. Moreover, since the 1990s, demonology, spiritual warfare and the practice of Deliverance have become increasingly popular features of Nigerian Pentecostalism.

description: Unmanned aerial vehicles (UAVs) frequently operate in partially or entirely unknown environments. As the vehicle traverses the environment and detects new obstacles, rapid path replanning is essential to avoid collisions. This thesis presents a new algorithm called Hierarchical D* Lite (HD*), which combines the incremental algorithm D* Lite with a novel hierarchical path planning approach to replan paths sufficiently fast for real-time operation. Unlike current hierarchical planning algorithms, HD* does not require map corrections before planning a new path. Directional cost scale factors, path smoothing, and Catmull-Rom splines are used to ensure the resulting paths are feasible. HD* sacrifices optimality for real-time performance. Its computation time and path quality are dependent on the map size, obstacle density, sensor range, and any restrictions on planning time. For the most complex scenarios tested, HD* found paths within 10% of optimal in under 35 milliseconds.

description: Using a simplified microscopic model of coupled spin and lattice excitations in a ferromagnetic insulator we evaluate the magnetic-field dependence of the spin Seebeck effect at low temperatures. The model includes Heisenberg exchange coupling, a harmonic lattice potential, and a pseudodipolar exchange interaction. Our approach goes beyond previous work [Phys. Rev. B 98, 134421 (2018)] in that it does not rely on the a priori assumption of a fast equilibration of the magnon and phonon distributions. Our theory shows that singular features in the magnetic-field dependence of the spin Seebeck effect at low temperatures observed by Kikkawa et al. [Phys. Rev. Lett. 117, 207203 (2016)] are independent of the relative strength of magnon-impurity and phonon-impurity scattering.

description: Invoking Justice, a performative work of dance-theater, is a social commentary, both on the failure of the American justice system to balance the scales, and on our individual and collective failings to balance our communities, and ourselves, while recognizing our inherent unity and interconnectedness. The show was performed on March 10th and 11th, 2016 in the Clarice Smith Performing Arts Center, at the University of Maryland, College Park.

	This document is a survey of the creative process through which this project was realized and serves as a record of the many obstacles and successes that one might encounter in directing a work of dance-theater.

"Let Us Sing as We Go": The Role of Music in the United States Suffrage Movement

description: Music played a prominent role in the United States women’s suffrage movement (1848–1920). Suffragists left behind hundreds of compositions supporting their cause and historical accounts indicate that musical performances were common at suffrage events. With only a few exceptions, scholars have disregarded the music used in this movement, and have underemphasized its significance. This study examines the use of music in the suffrage movement from three perspectives: music with lyrics, titles, and images that espouse women’s enfranchisement; music performed at national suffrage conventions held by the National American Woman Suffrage Association; and music accompanying suffrage parades. Though the music used varies in each case, it is clear that music played an important role in unifying suffragists and underscoring the ideals and goals of the movement.
Reaction coordinates in complex systems-a perspective

description: In molecular simulations, the identification of suitable reaction coordinates is central to both the analysis and sampling of transitions between metastable states in complex systems. If sufficient simulation data are available, a number of methods have been developed to reduce the vast amount of high-dimensional data to a small number of essential degrees of freedom representing the reaction coordinate. Likewise, if the reaction coordinate is known, a variety of approaches have been proposed to enhance the sampling along the important degrees of freedom. Often, however, neither one nor the other is available. One of the key questions is therefore, how to construct reaction coordinates and evaluate their validity. Another challenges arises from the physical interpretation of reaction coordinates, which is often addressed by correlating physically meaningful parameters with conceptually well-defined but abstract reaction coordinates. Furthermore, machine learning based methods are becoming more and more applicable also to the reaction coordinate problem. This perspective highlights central aspects in the identification and evaluation of reaction coordinates and discusses recent ideas regarding automated computational frameworks to combine the optimization of reaction coordinates and enhanced sampling.
Machtverhältnisse und die Problematik des postkolonialen Blicks in Uwe Timms Morenga (1978) und Gerhard Seyfrieds Herero (2003)

description: Using a postcolonial methodology within a German Cultural Studies framework, this thesis applies a close reading to Uwe Timm’s 1978 novel Morenga and Gerhard Seyfried’s 2003 novel Herero. Both novels narrate the colonial experience in German Southwest Africa during the 1904-1907 Herero and Nama uprising through the eyes of a German male protagonist. I investigate how notions of the ‘other’ become ingrained in the collective cultural imaginary of a nation and manifest themselves as inherent truths used to justify methods of subjugation. I also examine the conflicts that arise due to the clash between these drastically different cultures in the “contact zone”, a term I borrow from Mary Louise Pratt. Emphasis is placed on analyzing the ways in which the natives’ use of mimicry allows for the creation of a cultural hybridity in which power relations are constantly negotiated and re-evaluated. I also problematize the difficulty both protagonists demonstrate in their quest to abandon the colonial gaze in favor of adopting a postcolonial perspective, an attempt that often appears ambivalent at best.

description: In order to advance the mission of in silico cell biology, modeling the interactions of large and complex biological systems becomes increasingly relevant. The combination of molecular dynamics (MD) and Markov state models (MSMs) have enabled the construction of simplified models of molecular kinetics on long timescales. Despite its success, this approach is inherently limited by the size of the molecular system. With increasing size of macromolecular complexes, the number of independent or weakly coupled subsystems increases, and the number of global system states increase exponentially, making the sampling of all distinct global states unfeasible. In this work, we present a technique called Independent Markov Decomposition (IMD) that leverages weak coupling between subsystems in order to compute a global kinetic model without requiring to sample all combinatorial states of subsystems. We give a theoretical basis for IMD and propose an approach for finding and validating such a decomposition. Using empirical few-state MSMs of ion channel models that are well established in electrophysiology, we demonstrate that IMD can reproduce experimental conductance measurements with a major reduction in sampling compared with a standard MSM approach. We further show how to find the optimal partition of all-atom protein simulations into weakly coupled subunits.
