A Mathematical Study of Amplitudes Through Their Singularities
Authors:   , Godwin John
Published: May 2021

In this thesis, amplitudes in pure Yang-Mills and an extended theory of gravity are investigated through the use of four-dimensional gener-alised unitarity and recursive techniques. In particular, the two-loop all-plus helicity amplitude in Yang-Mills is examined which, when viewed through the lens of four-dimensional unitarity, has a singu-larity structure related to general one-loop amplitudes. This helicity amplitude is computed for n = 6, 7 at leading order in the number of colours, presenting new results for the rational terms of these ampli-tudes through augmented recursion. Augmented recursion deals with the complications faced when performing complex recursion on an amplitude that contains double poles in particular momentum chan-nels. A section is dedicated to reviewing this method in great detail. Additionally, the reach of four-dimensional unitarity and recursion is extended to all orders in the number of colours, and used to compute all partial amplitudes that contribute to the two-loop n = 5 all-plus amplitude in U(Nc) Yang-Mills. In the second half of the thesis, tree-level and one-loop amplitudes that arise in a theory of Einstein-Hilbert (EH) gravity extended by an αR3 term are examined. Such a theory provides counterterms for two-loop amplitudes in EH gravity. Focussing on the leading deformation of EH gravity, the O(α) tree-level S-Matrix is obtained solely by demanding the amplitudes fac-torise as a propagator goes on shell, and defining the O(α0) and O(α) three-point amplitudes. Finally, the renormalisability of the one-loop amplitudes in this theory are studied by using four-dimensional tech-niques to determine the UV singularities present in bubble integral functions.

El objetivo de esta investigación fue emplear con estudiantes de la carrera de abogado del Campus Universitario de los Valles (Universidad de Guadalajara) (específicamente en la asignatura Derecho Civil V, ubicada en el séptimo semestre) dos estrategias pedagógicas que fomentan la participación activa de los alumnos, es decir, el aprendizaje basado en problemas y el análisis de casos. El enfoque metodológico usado fue mixto (cualitativo y cuantitativo). Los resultados demuestran (utilizando el software SPSS) que, según el nivel de significancia, el hecho de que el alumno de la carrera de abogado asesore a un testador o presencie el otorgamiento de un testamento público abierto favorece su desempeño como estudiante. En conclusión, se puede asegurar que emplear el aprendizaje basado en problemas y el análisis de casos con estudiantes de la carrera de abogado puede acercarlos a la realidad jurídica con la que se enfrentarán al culminar su educación universitaria. Además, el hecho de preguntarles de manera verbal sobre problemas jurídicos fomenta la habilidad de hablar en público (oratoria), así como el aplicar el derecho positivo al caso concreto fundando y motivando su dicho.

Durante los últimos años se ha incrementado el desarrollo de modelos probabilísticos y de análisis estadísticos aplicados a datos de supervivencia. El modelo de riesgos proporcionales de Cox se ha convertido en uno de los más empleados, principalmente en temas relacionados con la salud, pues resulta particularmente útil para comparar grupos en los que se estudia el tiempo transcurrido hasta la ocurrencia de un evento, pudiendo analizar conjuntamente el efecto de varias variables. Por ende, el objetivo de este estudio es presentar los parámetros de validación de los supuestos del modelo de riesgos proporcionales de Cox como una herramienta para la toma de decisiones respecto al tiempo de ocurrencia del fenómeno, comparación de grupos, efectos de diferentes factores sobre el evento de desenlace o falla, así como destacar características que identifican a grupos de riesgo con el fin de proporcionar a los profesionales de la salud información estadística que les ayude a fundamentar decisiones en materia de diagnóstico, pronóstico y tratamiento. Esta, por tanto, es una investigación transversal exploratoria en donde se reportan los resultados obtenidos de un análisis estadístico realizado a los datos derivados de expedientes y entrevistas a un grupo de 127 pacientes diagnosticadas con cáncer cervicouterino durante el periodo 2013-2017 en la clínica de colposcopia de la Jurisdicción Sanitaria II en Cd. Juárez Chihuahua. Se analizaron los factores edad, diabetes, escolaridad, estado civil y cantidad de parejas con el fin de determinar su tasa de riesgo mediante el modelo de riesgos proporcionales de Cox. El estudio identificó que los factores que tiene mayor efecto en la supervivencia de pacientes son la edad y la diabetes. El modelo de Cox permite utilizar información de sujetos que se pierden durante el seguimiento, como sucede en los análisis de supervivencia, además de que toma en cuenta todos los factores de riesgo que pueden intervenir en un resultado dado.

Rollsiegel sequenzieren.
Authors: Schmitz Daniel , Wagner Thomas
Published: May 2021

The definition of subjects through the sequencing of cylinder seal rollings is a funda-mental step for the interpretation of a iconographic evidence. The perception of the images is largely determined by the arrangement of their symbols. In many cases, this is done intuitively, in that the unroller cuts the rolling in such a way as he perceives the motif arrangement at first glance. With cata- and anaphoric elements as well as the arrangement of the symbols aligned with the centre, this article describes essential compositional features that need to be perceived and considered when sequencing.
Mehr als nur ein Text. Erwägungen zu Lehr-/Lernpotentialen neutestamentlicher Handschriften am Beispiel des Codex Boernerianus
Authors: Künzl Kevin
Published: May 2021

Using the Dresden manuscript Codex Boernerianus as an example, the paper discusses a range of didactic possibilities to incorporate (New Testament) manuscripts into higher education in Biblical studies. It focuses on overcoming the association of man-uscripts with a barren form of textual criticism that very much limits itself to read-ing the apparatus criticus. Instead the present article exemplifies a holistic view on manuscripts as complex historical artifacts. This view does not only encompass using manuscripts to illustrate text critical and tradition historical phenomena, but also rec-ognizes their physical and optical features as well as their paratexts and side contents, all of which offer their own specific teaching and learning potentials.
Functional Method of Localization and LaSalle Invariance Principle
Authors: Kanatnikov A. N. , Krishchenko A. P.
Published: May 2021

A functional method of localization has proved to be good in solving the qualitative analysis problems of dynamic systems. Proposed in the 90s, it was intensively used when studying a number of well-known systems of differential equations, both of autonomous and of non-autonomous discrete systems, including systems that involve control and / or disturbances.

The method essence is to construct a set containing all invariant compact sets in the phase space of a dynamical system. A concept of the invariant compact set includes equilibrium positions, limit cycles, attractors, repellers, and other structures in the phase space of a system that play an important role in describing the behavior of a dynamical system. The constructed set is called localizing and represents an external assessment of the appropriate structures in the phase space.

Relatively recently, it was found that the functional localization method allows one to analyze a behavior of the dynamical system trajectories. In particular, the localization method can be used to check the stability of the equilibrium positions.

Here naturally emerges an issue of the relationship between the functional localization method and the well-known La Salle invariance principle, which can be regarded as a further development of the method of Lyapunov functions for establishing stability. The article discusses this issue.
Self-consistent Equation Method for Solving Problems of Wave Diffraction on Scatter Systems
Authors: Vetluzhsky A. Yu.
Published: May 2021

The paper considers one of the numerical methods to solve problems of scattering electromagnetic waves on the systems formed by parallel-oriented cylindrical elements – two-dimensional photonic crystals. The method is based on the classical partition approach used for solving the wave equation. Тhe method principle is to represent the field as the sum of the primary field and the unknown secondary field scattered on the medium elements. The mathematical expression for the latter is written as the infinite series according to elementary wave functions with unknown coefficients. In particular, the N elements-scattered field is found as the sum of N diffraction series in which one of the series is composed of the wave functions of one body and the wave functions in the remaining series are expressed in terms of the eigenfunctions of the first body using addition theorems. Further, to meet the boundary conditions, on the surface of each element, we obtain systems of linear algebraic equations with the infinite number of unknowns – the required expansion coefficients, which are solved by standard methods. A feature of the method is the use of analytical expressions to describe diffraction on a single element of the system. In contrast to most numerical methods, this approach allows one to obtain information on the amplitude-phase or spectral characteristics of the field only at the local points of the structure. The high efficiency of this method stems from the fact that there is no need to determine the field parameters in the entire area of space occupied by the multi-element system under consideration. The paper compares the calculated results of the transmission spectra of two-dimensional photonic crystals using the considered method with the experimental data and numerical results, obtained by other approaches, and demonstrates their good agreement.

Decolonizing Approach to Understanding Intimate Partner Violence in Belize
Authors: Warren-Gordon Kiesha
Published: May 2021

Countries like Belize, located in the Global South, often have limited financial resources to address problems such as intimate partner violence, and financial support from the Global North is often accompanied by the inherent problems caused by the effects of colonization. As violence is one of the leading causes of death for women in Belize, the need to understand the reasons is pronounced. A decolonized approached is utilized to center the voices of women who had been victims of intimate partner violence. In conducting this research I address, the W questions: who, why, where, and how, in order to recognize my role in the research process and to center the voices of the collaborators. All of the collaborators, through sharing their stories, revealed the impact of colonization on how they see themselves and the world around them. These findings indicate the need for further research on the effects of colonization, as well as the decolonization methods needed in order to restructure how victims of intimate partner abuse are treated and provided support

Authors: Mitran Madalina Irina , Tampa Mircea , Nicolae Ilinca , Mitran Cristina Iulia , Matei Clara , Georgescu Simona Roxana , Popa Mircea Ioan
Published: May 2021

Introduction. Lichen planus (LP) is a mucocutaneous T-cell mediated disorder of unknown etiology. There is growing evidence that oxidative stress is an important player in the pathogenesis of LP. Therefore, we have investigated oxidative stress markers in LP and the influence of hepatitis C virus (HCV) infection, a frequently associated condition, on oxidative stress in LP patients.

Method. We have determined the serum levels of 4- hydroxynonenal (4-HNE) and symmetric dimethylarginine (SDMA), as markers of oxidative stress, and total antioxidant capacity (TAC), as a marker of the antioxidant defence, in 4 groups: group A – HCV positive patients with LP (n=12), group B – HCV positive patients without LP (n=12), group C – HCV negative patients with LP (n=31) and group D – control group (n=26).

Results. In LP patients, we have identified an increased level of lipid peroxidation (4-HNE – group A – 8.41±1.11 μg/mL, group B - 7.97±2.17 μg/mL, group C – 7.81±1.96 μg/mL and group D – 6.15±1.17 μg/mL) and alterations in arginine methylation (SDMA – group A – 1.10±0.24 μmol/L, group B – 1.03±0.16 μmol/L, group C – 0.84±0.19 μmol/L and group D – 0.50±0.06 μmol/L) associated with a diminished antioxidant defence (TAC – group A – 234.50±49.96, μmol/L group B – 255.83±41.41 μmol/L, group C – 269.83±43.33 μmol/L and group D – 316.46 ±29.33 μmol/L), processes augmented by the association with HCV infection.

Conclusion. There is an imbalance between oxidants and antioxidants in patients with LP, an imbalance that is augmented by the presence of HCV infection. SDMA could be regarded as a novel biomarker of oxidative stress among these patients. To the best of our knowledge this is the first study to investigate the influence of HCV infection on oxidative stress in LP patients.
Legal Protection Against Customers Using Bank Aceh Co-Brand Bank Mandiri Credit Card Products After Bank Aceh Syari'ah Conversion
Authors: Salda Muhammad , Ridha Muhammad
Published: May 2021

Banking products are inseparable from the existence of an agreement between the Bank and the customer, as stipulated in Article 1338 paragraph (3) of the Civil Code, one of the requirements that must be met in applying the principle of freedom of contract is the good faith of the party making the agreement. Good faith in the implementation stage of the agreement is propriety, where the principle applies equally to both conventional and Sharia banking systems, one of the concrete forms of which is to provide clear information to customers. In this case, it turns out that the Bank Aceh product, namely the Bank Aceh Co-Brand Bank Mandiri credit card, does not provide clear information to customers that the products they use use conventional principles and have a time period. So that the legal problem is how the legal protection for customers who hold Sharia Card. The research was carried out using the empirical juridical research method using a statute approach. The results of the research show that for 3 years according to the time period agreed by the parties in the agreement of the Bank Aceh Co-Brand Credit Card, Bank Mandiri did not explain conversion problems, including ownership of databases, documents and rights, legal ownership of Bank Aceh data also gave to the Bank. Mandiri, as referred to in Article 5 paragraph (5.1.) Number 1 states that, "Bank Aceh is the legal owner of the Bank Aceh customer database provided to Bank Mandiri in connection with the cooperation as stipulated in this Agreement" this should be and is related to changes to the system of conventional to be shari'ah must be informed to the customer.

Based on the facts in decision No: 0429 / Pdt.G / 2016 / PA.Mtr due to the legal consequences of divorce due to financial factors and other reasons, the court obliges the ex-husband to provide living expenses and / or determine an obligation for the ex-wife. Before the marriage between a husband and a wife candidate should be more solidified in terms of physical and spiritual preparation and to officials at the Religious Courts, so that they can decide cases related to this factor of living more carefully and quickly so as not to cause harm to either party.

Remote Sensing for the Determination of the Woody-to-total Area Ratios in Mixedwood Forest Stands
Authors: Ezzio Sarah
Published: May 2021

Leaf area index (LAI) is a biophysical variable that is important for estimating processes such as productivity and yield rates in forest stands.  Indirect methods for estimating LAI (e.g., digital hemispherical photography (DHP)), provide efficient and reliable measurements.  However, DHP utilizes gap-fraction-based methods that are unable to both discriminate between leafy and other plant material and compensate for the non-random positioning of canopy elements.  Therefore, LAI estimates obtained with these techniques can be termed effective leaf area index (LAIe).  Woody-to-total area ratios are applied to these measurements to compensate for the inclusion of non-photosynthetic canopy components, but these parameters vary amongst tree species and are not well studied.  This project attempts to determine LAI for mixedwood stands (i.e., deciduous and coniferous) by examining the woody-to-total area ratio for species in the Haliburton Forest located in southeastern Ontario.  Two sets of DHPs were taken for 23 stem-mapped forest plots during field campaigns carried out in leaf-on and leaf-off periods to establish the impact of non-photosynthetic materials on estimating LAI.  For solely deciduous stands, the woody-to-total area ratio is assumed to be directly equal to the difference in LAIe values between these two periods.  For purely coniferous stands, the woody-total area ratio will be derived in the same manner for leaf-on and leaf-off conditions (i.e., with correction factors applied based on published ratios and corresponding to the basal area ratio of conifers). For mixed stands, the proportions of conifers (in terms of BA) to deciduous species will be used to determine appropriate models for estimating LAIe.
Angiotensin 1-7 Reduces Right Ventricular Hypertrophy and Fibrosis in a Rat Model of monocrotaline Induced Pulmonary Arterial Hypertension
Authors: Kim Laura
Published: May 2021

Background: Pulmonary arterial hypertension (PAH), characterized by high pressure in the pulmonary arteries, is fatal due to the development of right ventricular (RV) failure. Angiotensin-1-7 (Ang-(1-7)) is a metabolite of Angiotensin I/ II that has beneficial effects on pulmonary vascular remodelling in animal models of PAH. However its effect on RV myocardial remodelling in PAH is unknown.Objective: To study the effects of Ang-(1-7) on RV hypertrophy and fibrosis in an experimental PAH model.Methods: 220 gram Sprague-Dawley rats were randomized to: sham-controls (n=2), monocrotaline (MCT) induced PAH (n=3) and PAH + Ang-1-7 administered via subcutaneous injection for 5-weeks following injection of MCT (n=4). Animals were sacrificed at 5-weeks and the heart harvested for investigation of RV wall thickness and collagen content.Results: RV wall thickness was increased in the MCT-group (70.3  2.3 pixels vs. sham-controls 50.42  2.1 pixels p=0.0001) and decreased towards control values with the addition of Ang-(1-7) (52.7 1.9, p=0.0001 vs. MCT). RV myocardial collagen increased in the MCT-group (6.70.8 % vs. shams 2.70.2 %, p=0.0001) and decreased with the addition of Ang-(1-7) (5.60.2 %, p=0.04 vs. MCT).Conclusions:  Ang-(1-7) reduces development of RV hypertrophy and fibrosis in MCT-induced PAH in rats, despite similar pulmonary arterial pressures. Further study is needed to investigate whether Ang-(1-7) improves RV performance and clinical outcomes in experimental and clinical settings.
Fashioning an Identity: A Study of Dutch and Flemish Portraits from the Agnes Etherington Art Centre
Authors: Leisk Madeleine
Published: May 2021

Portraiture developed as a distinct genre of art during the Renaissance in response to the growing interest in humanism. The new humanist ideal placed emphasis on individual human identity and critical thinking. This interest in the individual resulted in the growth of portraiture. During the early development of this genre, portraits were reserved for the elite and commissioned by members of the aristocracy. The high cost and perceived egotism associated with commissioning a portrait meant that it was not a popular or accessible genre of art for the general public during the Renaissance. This stagnant state of portraiture transformed with the economic growth in the Netherlands during the Seventeenth Century often referred to as the Dutch Golden Age. Dutch international trade created a period of economic prosperity during the Seventeenth Century that resulted in a rapidly expanding middle class. Through investments in trade, individuals began amassing wealth and, in turn, status. The rising middle class combined with a shift away from inherited titles and the aristocracy created a unique social position in the Netherlands whereby status was based on financial wealth and the Dutch could fabricate their own identities. My research examines the use of portraits to shape identity through the study of a selection of portraits from the Agnes Etherington Art Centre. These works can tell the viewer about the sitters’ public and or perceived private life as well as the society they belonged to through the study of their physical appearance, setting, attributes and stylistic choices.
Deserted Medieval Villages in Sussex, England
Authors: Skelton Kate
Published: May 2021

The topic of the poster which I wish to submit originally served as the subject of a USSRF research fellowship project which I completed during the summer of 2015 at the Bader International Study Centre, under my supervisor Dr. Scott McLean. The poster serves as a condensed summary of a longer essay which I wrote during my time at the BISC. My final poster, entitled “Deserted Medieval Villages in Sussex, England,” looks closely at some of the patterns of displacement and resettlement which occurred around the southeastern coast of England during the medieval period. The poster identifies three primary causes of village desertion which were prevalent in this setting: environmental (particularly coastal) change, economic change (i.e. the decline of the salt industry), and social change (from rapid population growth and collapse). I then demonstrate the impact of these themes by more closely analyzing the development and decline of four particular deserted villages within East Sussex: Herste, Hooe, Manxey and Northeye. The ultimate goal of this poster is to consider how the broader issues of environmental, economic and social change influenced human settlement patterns on a more localized scale, and how some of the patterns and differences which are present within such examples may reflect broader themes of life and desertion in medieval English settlements.
Perfluorooctane Sulfonate and Perfluorooctanoic Acid as Emerging Contaminants
Authors: Turner Lauren
Published: May 2021

Perfluoroocatane sulfonate (PFOS) and perfluororooctanoic acid (PFOA) are perfluorinated carbons (PFCs) with varying applications for surface coatings and surfactants. They were produced in mass quantities before an overwhelming international movement to reduce production and use. As a result of manufacturing and widespread usage, distribution of the compounds in the environment and wildlife is apparent and concerning. PFOS and PFOA are highly persistent in the environment and accumulate in organisms, plants and groundwater. PFOS and PFOA concentrate in blood serum and the liver; the compounds have been noted to have negative biological implications in humans, wildlife and laboratory treated animals.  Identified as emerging contaminants worldwide, governments and organizations including Environment and Climate Change Canada, The United States Environmental Protection Agency, The European Food Safety Authority and United Nations Environmental Programme agree effects are detrimental to human and environmental health.  Remediation strategies are currently being studied and developed to identify possible technologies for full scale economical implementation. The presentation encompasses the physico-­‐chemical properties, partitioning, transport behaviour, health effects and current remediation technologies relevant to PFOS and PFOA groundwater contamination.
Potential Nitric Oxide Treatment for Alleviating Muscle Atrophy in Hindlimb-Suspended Mice
Authors: Zhu Antonia
Published: May 2021

Muscle atrophy is a debilitating condition that results from muscle disuse and aging. It is often experienced by people who are sedentary or elderly and cannot be effectively treated or prevented. Since nitric oxide (NO) activates muscle stem cells, this study aimed to test the hypothesis that treatment with a NO-donor drug, isosorbide dinitrate, during hindlimb suspension for 18 days, can alleviate muscle atrophy. Muscles in unloaded lower and weight-bearing upper limbs were weighed to study muscle loss. Western blots were used to measure protein levels in experimental (suspended and treated-suspended) and age-matched control groups of young (3 weeks old) and adult (6-8 weeks old) mice. Protein levels of atrogin-1, myostatin, and myosin heavy chain isoforms were analyzed (relative to ß-actin) for changes expected with muscle atrophy. Analysis of variance was used to determine if changes were statistically significant. The weight of unloaded muscles (quadriceps and soleus) in NO-treated-suspended mice tended to increase towards that of the control mice, compared to the atrophy after suspension without treatment. In the same muscles of young and adult suspended mice, NO treatment decreased atrogin-1, a negative regulator of muscle mass (p<0.05 for quadriceps). A precursor protein of myostatin, an inhibitor of myogenesis, showed the same trend. Results suggest that NO treatment has the potential to attenuate muscle-disuse atrophy, with possible significance to preventing atrophy with aging or space travel.

Soldier or Artist? An Investigation into the Possible Roman Origins of Footprint Petroglyphs from Humayma
Authors: Zmijowskyj Ally
Published: May 2021

The archaeological site of Humayma in southern Jordan contains traces of human occupation spanning the Neolithic period through to the present day, with major occupation associated with the Nabatean, Roman, Byzantine and early Islamic settlements dating from the 1st century BC to the 8th century AD. Petroglyphs of feet carved into the sandstone landmasses next to the site could conceivably be associated with any of these population groups. The goal of this study is to investigate the possibility that some may have been carved by soldiers of the Roman garrison who were stationed at Humayma from the early 2nd C AD to the early 5th C AD. Specific aspects of Humayma’s foot petroglyphs (e.g. shape, dimensions, details) will be compared to published descriptions of Roman military footwear and to depictions in Roman art to determine the likelihood that Roman soldiers garrisoned at Humayma created these carvings. Further comparison of the nature and context of these carvings against other depictions of shoes, bare feet, footprints in Roman art may establish motives behind the creation of these petroglyphs. The findings as to whether or not support the theory that Roman soldiers likely created these petroglyphs will provide important information for understanding the activities of Humayma’s soldiers and the identity of those carving foot petroglyphs at Humayma and in the surrounding region.
Group 6: Satanism
Authors: Melissa Naami Melissa , Myszko Marnie , Nijhuis Stephanie , Kulinich Martin , Worth Madison
Published: May 2021

This poster will discuss the origins of Satanism by looking at the beliefs and intentions of its founder, Anton LaVey, who founded the Church of Satan in San Francisco in 1966. Two types of Satanism that developed from these origins will be compared: Rational Satanism and Esoteric Satanism. This poster will contextualize these movements by drawing on contemporary religious studies sources that highlight Satanism as a reaction to modernity. It will also consider the negative cultural connotations attached to being a Satanist. Consistent with the scholarly literature, this poster argues that due to these negative connotations, Satanism is usually not viewed as a religion but rather a ‘cult,’ a term which carries its own negative connotations. These connotations are explained with reference to the history of the early 20th C Christian counter-cult movement and the mid-20th C secular anti-cult movement. This poster looks to relate the beliefs and practices of both branches of Satanism to those commonly associated with major world religions. In doing so, it seeks to broaden the audience’s understanding of what Satanism is and what beliefs and practices Satanists are committed to.
