A Parametric Framework and Tool for Posing Photorealistic Facial Expressions in 3D Characters
Creators: name: Romana, Amrinder
Publisher: name: Leeds Beckett University
Year: 2025

description: This research introduces a parametric framework to address the lack of educational resources for teaching realistic facial animation in digital characters, focusing on developing a Parametric Framework and Tool for Posing Photorealistic 3D Character Facial Expressions. The research applies the Facial Action Coding System (FACS), essential for understanding a wide range of realistic facial movements and enhancing digital characters' emotional depth and reliability. A novel innovation of the thesis is a tool that offers animators control over the range of movement of facial expressions. This tool's parametric functionality enables detailed, incremental adjustments, capturing human emotions' subtleties in digital form. The study demonstrates a systematic approach to developing a Parametric Framework and Tool for posing photorealistic 3D character facial expressions. It employs a Design Science Research Methodology, focusing on practical solution-oriented research. Key stages include problem identification, defining objectives, design and development of the tool, demonstration, evaluation, and communication. The process is iterative, integrating knowledge from facial expression theory, animation, computer graphics, and user interface design. The methodology emphasises user testing with animators and learners, incorporating feedback to refine the tool, ensuring practicality and utility for its intended users. The thesis emphasises successfully developing a Parametric Framework and Tool and highlights advancements in bridging the gap between theoretical knowledge and practical application in facial animation. The thesis concludes by underscoring the potential impact of this work on the animation industry, improving the emotional depth and realism of digital characters. Future directions for research and development are suggested, focusing on further enhancing the tool's capabilities and exploring new applications in various digital media contexts.
Whole rock geochemistry and mineral chemistry of the Hanging Wall Sequence, Hellyer deposit, Tasmania
Creators: name: Fulton, R
Publisher: name: University Of Tasmania
Year: 2023

description: Hellyer is a 17 Mt, high-grade, polymetallic VHMS-style deposit containing 13.0% Zn, 6.8% Pb, 0.3% Cu, 160 g/t Ag and 2.3 g/t Au (Gemmell and Large, 1992) located in western Tasmania's Mt. Read Volcanics belt. Analysis of the Hellyer core log database shows that there are five main types of alteration within the Hellyer basalt; (1) silica-albite, (2) fuchsite (¬¨¬±carbonate), (3) chlorite, (4) carbonate and (5) sericite, of which the first two are the most significant volumetrically. The pillow lava facies of the Hellyer hanging wall basalt has principally undergone fuchsite and chlorite dominant alteration, whereas the massive lava facies is typically affected by carbonate, silica-albite, or epidote dominant alteration The breccia facies behaves similarly to the massive lava facies but sericite dominant alteration also occurs. Three-dimensional computer modelling of the database indicates that silica-albite-dominant alteration is best developed on the flanks of the ore body and to the south and west. Fuchsite dominant alteration, is well developed vertically above the ore body. Carbonate dominant alteration is sparsely distributed about the ore body. Chlorite-dominant alteration is best developed above the ore body and more laterally than the fuchsite-dominant alteration. Sericite-dominant alteration occurs to the south of the ore body and laterally above the northern end of the orebody. A lithogeochemical halo of Sb occurs within the basalt from immediately above the ore deposit to immediately beneath the overlying Que River Shale and provides an excellent vector to the Hellyer deposit. The halo spreads out beneath the Que River Shale for at least 400 metres west, and up to 900 metres north-east. Other geochemical parameters which show are useful in defining the halo are Tl, As, Ba, Ba/Sr and Cs. The halo has been previously defined by apple green \fuchsite\" altereration visible in hand specimen. The commodity elements Cu Pb and Zn are rarely elevated within the Hellyer basalt. The Ba content of white mica has been found to increase with proximity to the Hellyer deposit and this is the only mineral chemistry vector to the deposit identified. Although widely recorded in core logs and visible in hand specimen fuchsite-altered rocks contain very little true fuchsite. Most white mica is chromian muscovite with Cr20 3 less than 1%. Chlorites have been found to contain up to to 2.44% Cr20 3. Barium-rich samples of basalt have been found to contain barium-rich feldspars with up to 5.58% BaO similar to feldspars reported from the Hellyer footwall and the nearby Que River deposit. "

description: This paper reports the synthesis and superconducting behaviors of the tetragonal iron-chalcogenide superconductor FeSe. The electrical resistivity and magnetic moment measurements confirmed its superconductivity with a $T_c^{zero}$ and $T_c^{mag}$ at 9.4 K under ambient pressure. EPMA indicated the sample to have a stoichiometric Fe:Se ratio of 1:1 ($\pm$0.02). The Seebeck coefficient which was 12.3 $μ$V/K at room temperature, changed to a negative value near 200 K, indicating it to be a two carriers material. Above $T_c$, the $ρ(T)$ curve revealed an 'S' shape. Hence $dρ(T)/dT$, and $d^2ρ(T)/dT^2$ showed pseudogap-like behavior at $T^*$=110 K according to the resistivity curvature mapping (RCM) method for high $T_c$ cuprates. Moreover, the magnetoresistance $ρ_H(T)/ρ_{H=0}$ under a magnetic field and the Seebeck coefficient $S(T)$ revealed revealed pseudogap-like behavior near $T^*$. Interestingly, at the same temperature, 30 K, the sign of $S(T)$ and all signs of $d^2ρ(T)/dT^2$ changed from negative to positive above $T_c$.

description: Das Verhältnis von Adel und Militär beruhte lange Zeit auf der bereits für die preußischen Kernprovinzen widerlegten Annahme, dass Besitzarmut die Neigung eines adligen Rittergutbesitzers zum Militär wesentlich bestimmte. Die Analyse der beiden östlichsten bisher noch nicht untersuchten Provinzen Preußens kommt speziell für Ostpreußen zur gleichen Erkenntnis – zu Westpreußen war die Quellenlage nicht aussagekräftig genug. Für das ausgehende 18. Jahrhundert zeigte damit der ostpreußische Adel eine ähnliche militärische Dienstbereitschaft wie die bisher untersuchten Provinzen, einen „Sonderweg“ für einen Eintritt in das preußische Militär hatte es daher nicht gegeben. Das unterschiedliche militärische Engagement eines Adligen war von mehreren Faktoren bestimmt. Sowohl Elemente des adelsständischen Regionalismus wie auch Familientraditionen bzw. Netzwerkbeziehungen und eben nur bedingt sozioökonomische Rahmenbedingungen waren verantwortlich, ob ein Adliger bereit war, in der preußischen Armee zu dienen.
description: It was long assumed that the relationship between aristocracy and military, and therefore the inclination of a lord of the manor to the latter, was largely governed by possession poverty, a theory that already has been invalidated for the central Prussian provinces. The analysis of the two easternmost Prussian provinces, which have not yet been researched, comes to the same conclusion, especially for East Prussia - the sources for West Prussia were not conclusive enough. Towards the end of the 18th century, the East Prussian noble appeared to have similar military service commitment as the already reasearched provinces, therefore it is believed that no special permission to enter the Prussia military service has been given. Several factors influenced the different aristocratic military engagements such as regional elements of nobility, family traditions or network relationships. Socio-economic conditions only partially influenced the willingness of an aristocrat to serve the Prussia military.

description: We study the DC transport of finite graphene samples with random gap. Using Dirac fermions to describe the low-energy physics near the Dirac point, we employ a generalized Drude form for the conductivity. The latter is constant for a vanishing average gap but always decreases with increasing sample size for a nonzero average gap. The asymptotic conductivity of the infinite sample is either nonzero if the average gap is smaller than a critical value or zero otherwise. Our results are in agreement with recent numerical calculations of Bardarson et al..

We obtain an approximate solution that reduces to the Kerr solution when a coupling constant vanishes. The Chern-Simons correction effectively reduces the frame-dragging effect around a black hole in comparison with that of the Kerr solution.

description: Communication of quantized information is frequently followed by a computation. We consider situations of \emph{distributed functional scalar quantization}: distributed scalar quantization of (possibly correlated) sources followed by centralized computation of a function. Under smoothness conditions on the sources and function, companding scalar quantizer designs are developed to minimize mean-squared error (MSE) of the computed function as the quantizer resolution is allowed to grow. Striking improvements over quantizers designed without consideration of the function are possible and are larger in the entropy-constrained setting than in the fixed-rate setting. As extensions to the basic analysis, we characterize a large class of functions for which regular quantization suffices, consider certain functions for which asymptotic optimality is achieved without arbitrarily fine quantization, and allow limited collaboration between source encoders. In the entropy-constrained setting, a single bit per sample communicated between encoders can have an arbitrarily-large effect on functional distortion. In contrast, such communication has very little effect in the fixed-rate setting.

description: Christopher Columbus became a public-and controversial-figure the moment his letters of February and March 1493, giving an account of his voyage to the Indies were read by Europeans. Almost immediately, contemporary writers began to write about the mysterious Genoese, his achievements and his motives. Since the 16th century, the Columbian bibliography has grown by many titles, some written to coincide with an anniversary of Columbus's first voyage, others when newly discovered documentation has revealed unknown facts. The 500th anniversary in particular has stimulated the production not only of new biographies and translations but also of bibliographies, dictionaries, encyclopedias, novels, poetry, operas, plays, motion pictures, and children's books. This bibliography is a highly selective listing of both popular and research printed sources.

description: Today, variants of the story of King Leir are addressed as either sources for, or adaptations of, Shakespeare’s King Lear. This linear and teleological approach has unnecessarily obscured a rich and complex palimpsest of cognate variants of the Leir story that existed in the early modern era. In this thesis, a new method, the historical collation, is proposed and utilised in order to understand this palimpsest. A historical collation of the bibliographic, paratextual, and narrative elements of substantive retellings of the Leir story, found in works printed in the British Isles between 1557 and 1710, reveals several trends and influences within the palimpsest. Variants of the Leir story were initially consistent and conservative, factual historiographies written to praise the monarch and the nation. Then, driven by trends within the book trade, and the diversification of historical genres, variants of the Leir story fractured and diversified in content and context, with the exigencies of new generic forms motivating the inclusion of topicalities and fictional elements. Finally, responding to trends within historiography, variants of the Leir story stagnated in number, style, and content, largely failing to respond to the politicised nature of contemporary print. Co-occurring with, but not causing this stagnation, was Shakespeare’s nascent canonisation, with the story of King Leir no longer relevant as a history, but instead becoming sought after as a Shakespearean creation. Thus, a historical collation illuminates the palimpsest of early modern variants of the Leir story and reveals trends within the book trade as its greatest influence, impacting first upon the diversification and popularisation of the traditional historiography, and then upon its stagnation and regeneration.

description: This thesis explores the foreign policy motivations of Hezbollah, an armed political movement (APM), with a particular focus on its interventions in Syria and Iraq. The central question of this study is: What are Hezbollah’s foreign policy motivations? To answer this question, the thesis employs a two-layered conception of security, encompassing both physical and ontological dimensions, and examines the interplay between material and ideational factors. Physical security refers to the survival of the actor, whether it is a state or a movement, and considers the physical dangers faced by the actor. Ontological security, on the other hand, pertains to the distinctiveness of the actor's identity in relation to an "Other." By analyzing these dimensions, the thesis aims to shed light on Hezbollah's foreign policy motivations. The study utilizes two case studies: Hezbollah's military intervention in Syria following the 2011 uprising, and its undisclosed involvement in Iraq after the 2003 US invasion, as well as its more overt military intervention in 2014. The thesis argues that the Syrian Uprising threatened Hezbollah's physical security, leading the party to engage in a large-scale military intervention. Additionally, Hezbollah's ontological security required reinforcement, which was achieved through emphasizing the distinctiveness of its identity while demonizing the “Other’s” identity. Following the US invasion of Iraq, Hezbollah's ontological security, centered around its narrative of supporting the "oppressed" and defending holy shrines, was at stake. A stable US occupation of Iraq posed a strategic physical threat to Hezbollah and its allies in the "Axis of Resistance." Furthermore, the Arab Uprisings and the subsequent ISIS takeover of Mosul posed a direct physical threat to Hezbollah's security, prompting it to publicly acknowledge its military involvement in Iraq. In addition to its theoretical contribution, the thesis presents original information based on unpublished data, providing insights into the motives behind Hezbollah's military interventions in Syria and Iraq.

description: Materials that undergo internal transformations are usually described in solid mechanics by multi-well energy functions that account for both elastic and transformational behavior. In order to separate the two effects, physicists use instead phase-field-type theories where conventional linear elastic strain is quadratically coupled to an additional field that describes the evolution of the reference state and solely accounts for nonlinearity. In this paper we propose a systematic method allowing one to split the non-convex energy into harmonic and nonharmonic parts and to convert a nonconvex mechanical problem into a partially linearized phase-field problem. The main ideas are illustrated using the simplest framework of the Peierls-Nabarro dislocation model.

Are local government authorities in Australia reporting on sustainability?
Creators: name: Williams, Belinda
Publisher: name: University Of Tasmania
Year: 2023

description: Ball (2004a) in describing the up-take of sustainability reporting in the public sector suggests that it is 'seemingly patchy' whilst Tort et al. (2010) and Dickenson et al. (2005) described it as an emerging field in its infancy approached on an ad hoc basis. This study contributes to the debate by examining sustainability reporting within the public sector specifically focused on local government authorities in Australia. Reporting by these authorities on sustainability is examined from a communication theory perspective. The study looks at the key factors in establishing sustainability reporting, the use of accountants in this process and the types of reporting frameworks that are being used. Finally, a broad reporting framework is developed specific to local government intended to act as a guide in the advancement of the sustainability reporting agenda in the sector. A triangulated approach was adopted for this study utilizing mail survey and interview techniques. Subjects for the mail survey were chief financial officers (CFOs) of all local government authorities in Australia. One hundred and ninety usable responses were returned, providing a usable response rate of 35.51%. To supplement and enrich the data provided by the mail survey, twenty-two interviews across sixteen organizations were then conducted. The results indicate that local government authorities in Australia are reporting on sustainability. Such reporting appears, though, to be inconsistent in focus and in location of the reported information. Further, significant differences were found in reporting levels between urban and rural local authorities. Key leadership support and stakeholder engagement were found to be the two key factors driving the establishment of sustainability reporting in local government in Australia. The results indicate that accountants play a role in the sustainability reporting process though in a limited capacity. Finally, a number of reporting frameworks are being utilized by local government authorities with the expected framework, the GRI guidelines, being utilized by few. A number of areas for further research were highlighted including the potential effects of mandatory reporting requirements on local government sustainability reporting practices, the exploration of the significant occurrence of social reporting highlighted in this study and research that examines restraints on sustainability reporting. In doing so, such research will assist in the further development of a more coherent knowledge and understanding of sustainability reporting in the local government sector.

Creators: name: Dalton, Maria

description: What is a tea lady? Tea ladies are often popularly understood as marginal figures. However, throughout the 1990s peace process in Northern Ireland, women who were referred to as the ‘tea ladies’ by skeptical male counterparts were central figures in the Province’s path towards peace and reconciliation. This thesis explores the role of women as peacemakers and peacebuilders in 1990s Northern Ireland. It offers a multi-level analysis of women’s contributions at the community, political and British governmental level. Through the use of interview data and archival evidence, this thesis plays an important role in restoring women’s voices and experiences to the historical record. The argument put forward is that, in order to fully understand and appreciate many of the contributions made by the women discussed in this thesis, it is vital to consider the impact of ‘micro-gestures’ and daily occurrences, whether they be the toss of a wig, a hug, or a friendship spawned from an interface Christmas party. In order to fully appreciate the significance of the achievements made by peacemakers and peacebuilders, whether they be male or female, attention must be given to the barely visible and the unquantifiable- the violence that did not happen, the lives that were not lost. As well as offering a detailed women’s history of the Northern Irish Peace Process, this thesis will engage with wider theorizations on gender and peacemaking and illustrate the ways in which gender has the potential to impact change at the peace table.

description: We study an experimental search of a GeV scale vector boson at BES-III/BEPCII. It is responsible for mediating a new U(1)$_d$ interaction, as recently exploited in the context of weakly interacting massive particle dark matter. At low energy $e^+ e^-$ colliders this dark state can be efficiently probed. We discuss the direct productions of this light vector $U$ boson and the decay of this state with BES-III data and its foreseen larger data. In particular, we show that Higgs' strahlung in the dark sector can lead to multilepton signatures, which probe the physics range for kinetic mixing parameter $ε\sim 10^{-4} -10^{-3}$ over a large portion of the parameter space.

description: Feminism is about challenging power in all its forms. Applying a feminist lens to scientific research brings many advantages, such as broadening theoretical perspectives, encouraging collaboration with—and inclusion of—marginalized groups, and widening the scope of research methods. However, findings from an informal survey as part of a SIPS hackathon revealed that both academics and non-academics grapple with a lack of clear conceptual understanding regarding feminist approaches and feminism as a whole. We aim for this perspective piece to provide an access point for why researchers should incorporate feminist approaches in psychological science, what feminist approaches look like and how researchers can start incorporating them into their own work. In answering the why, what and how of feminist practices, we aim to make working in a feminist way more legible and accessible, with the ultimate aim of cultivating a more comprehensive understanding of human psychology while fostering diverse perspectives. Based on the survey and our unique viewpoints as feminist ECRs working in different domains of psychological science, we propose constructive approaches for integrating feminist values and practices into the domain of psychological science. We highlight what possible barriers exist to incorporating feminist practices into one‘s own work and how future research can embrace feminist practices. We also provide a short glossary explaining terminology that can support the communication of feminist research as well as a curated checklist of feminist practices to start out with. This perspective warmly invites—and promotes—researchers from all backgrounds to engage in and contribute to the exploration of feminist values and practices within the realm of psychological science.

description: We introduce lossless state detection of trapped neutral atoms based on cavity-enhanced fluorescence. In an experiment with a single 87-Rb atom, a hyperfine-state-detection fidelity of 99.4% is achieved in 85 microseconds. The quantum bit is interrogated many hundreds of times without loss of the atom while a result is obtained in every readout attempt. The fidelity proves robust against atomic frequency shifts induced by the trapping potential. Our scheme does not require strong coupling between the atom and cavity and can be generalized to other systems with an optically accessible quantum bit.

description: We discuss multiscale simulations of long biopolymer translocation through wide nanopores that can accommodate multiple polymer strands. The simulations provide clear evidence of folding quantization, namely, the translocation proceeds through multi-folded configurations characterized by a well-defined integer number of folds. As a consequence, the translocation time acquires a dependence on the average folding number, which results in a deviation from the single-exponent power-law characterizing single-file translocation through narrow pores. The mechanism of folding quantization allows polymers above a threshold length (approximately $1,000$ persistence lengths for double-stranded DNA) to exhibit cooperative behavior and as a result to translocate noticeably faster.

description: We consider spatially homogeneous and isotropic Friedmann-Robertson-Walker (FRW) solutions of Milgrom's recently proposed class of bimetric theories of gravity. These theories have two different regimes, corresponding to high and low acceleration. We find simple power-law matter dominated solutions in both, as well as solutions with spatial curvature, and exponentially expanding solutions. In the high acceleration limit these solutions behave like the FRW solutions of General Relativity, with a cosmological constant term that is of the correct order of magnitude to explain the observed accelerating expansion of the Universe. We find that solutions that remain in the high acceleration regime for their entire history, however, require non-baryonic dark matter fields, or extra interaction terms in their gravitational Lagrangian, in order to be observationally viable. The low acceleration regime also provides some scope to account for this deficit, with solutions that differ considerably from their general relativistic counterparts.

Consumer practices of low income families in Vancouver, Winnipeg and Halifax
Creators: name: Geoffrey, Barbara
Publisher: name: University of British Columbia
Year: 2011

description: This is a study of low income family expenditure patterns in urban Canada based on data contained in the National Urban Low Income Family Evaluation study. The structured interview method with open-ended questions as set up in the NULIFE study offered data gathered between January 1 to April 15, 1967. Using this data, the relationships between total family income and expenditures on shelter, food and all other expenditures were examined. This data also shows that the relationship between expenditures on shelter, food, and other basic expenses were related to family sizes of one, three, and five person families within Vancouver, Winnipeg and Halifax. Correlation coefficients yielded two negative correlations about expenditures on shelter and food, inferring a positive correlation about expenditures on all other expenses. Findings showed a relationship between income and expenditure as follows: as income increases, percentage of expenditure on shelter and food decreases. At the same time, there was an increased percentage of income spent on other categories grouped together. Relationships for different family sizes and regions indicated trends between the expenditure on shelter, food, and all other basic expenses. Public housing areas within the Winnipeg and Halifax samples influence shelter costs. The one person family had the highest percentage expenditure on shelter in all three cities, whereas the five person family generally had the highest percentage expenditure on food. The three person family had the highest percentage expenditure on all other basic expenses. The Vancouver sample generally had the highest income. With a slightly lower income than Vancouver, the Winnipeg sample had the lowest percentage expenditure on shelter and the highest on all other basic expenses. Halifax, with the lowest income had the highest percentage expenditure on shelter, generally the highest on food, and the lowest percentage expenditure on all other basic expenses. This project has limited value due to the fact that the computer did not produce data such as age and composition of family units which might have yielded more detailed information.

This removal of text resulted in the loss of large portions of a significant document from the convict era in New South Wales, Van Diemen's Land and Norfolk Island. The narrative is told from the point of view of an illiterate Irish convict. It is established that Cash's recall of his twenty-seven years in the British penal system and Burke's scribing and co-authoring produced a narrative/manuscript which adds fresh dimensions to the historiography of time and place and also buttresses already known data. The basic dilemma was to establish a methodology which both separated and rejoined the exclusions into the full manuscript and in the process examine the origins and meanings of the omissions. With the separation and rejoining of the text in mind, the thesis examines the Cash/Burke narrative/manuscript closely by extricating Cash's words and experiences from sometimes seemingly unconnected material inserted by Burke or others. By reinstating the missing material from the twelve editions of 1880-1981, a fuller understanding of a long-term convict's experience within the British penal system emerges. Also examined is the relationship the Cash/Burke work has with Marcus Clarke's For the Term of His Natural Life. The result is the reconstruction of the Cash/Burke narrative/manuscript as a primary source from the years 1828-1855. This reconstructed information is in addition to material gained from official records, the opinions of contemporaries, newspaper reports and the mythology of bushranger Cash. Burke's role in the production may be referred to in a number of ways as 'editor', 'biographer', 'amanuensis', 'co-author' 'scribe' or 'author'. He was all of these. For the purpose of this thesis, the term 'co-author' will be the operative definition. The result is a new examination of an overlooked Australian colonial manuscript.

description: The majority of running geothermal plants worldwide are located in geological settings with convection- or advection-dominant heat transport. In Germany as in most regions in Europe, conduction is the dominating heat transport mechanism, with a resulting average geothermal gradient. The geothermal play type concept is a modern methodology to group geothermal resources according to their geological setting, and characteristic heat transport mechanisms. In particular, the quantity of heat transport is related to fluid flow in natural or engineered geothermal reservoirs. Hence, the permeability structure is a key element for geothermal play typing. Following the existing geothermal play type catalogue, four major geothermal play types can be identified for Germany: intracratonic basins, foreland basins and basement/crystalline rock provinces as conduction-dominated play types, and extensional terrains as the convection-dominated play type. The installed capacity of geothermal facilities sums up to 397.1 MWth by the end of 2018. District heating plants accounted for the largest portion, with about 337.0 MWth. The majority of these installations are located in the play type 'foreland basin', namely the Molasse Basin in southern Germany. The stratigraphic unit for geothermal use is the Upper Jurassic, also known as 'Malm' formation, a carbonate reservoir with high variability in porosity and permeability. Recently drilled wells in the southernmost Molasse Basin indicate the Upper Jurassic as a tight, fracture-controlled reservoir, not usable for conventional hydrothermal well doublets. Our new data compilation including the recently drilled deep geothermal well Geretsried reveals the relation of porosity and permeability to depth. The results suggest that obviously diagenetic processes control permeability with depth in carbonate rock, diminishing the predictability of reservoir porosity and permeability. The play type concept helps to delineate these property variations in play type levels because it is based on geological constraints, common for exploration geology. Following the general idea of play typing, the results from this play analysis can be transferred to geological analogues as carbonate rock play levels in varying depth. © The Author(s) 2020.

description: In this paper for a class of symmetric multiparty pure states we consider a conjecture related to the geometric measure of entanglement: 'for a symmetric pure state, the closest product state in terms of the fidelity can be chosen as a symmetric product state'. We show that this conjecture is true for symmetric pure states whose amplitudes are all non-negative in a computational basis. The more general conjecture is still open.

description: Radiation spectrum from high energy $e^\pm$ in a bent crystal with arbitrary curvature distribution along the longitudinal coordinate is evaluated, based on the stationary phase approximation. For a uniformly bent crystal a closed-form expression for the spectrum is derived. Features such as sharp end of spectrum and volume reflection turnover at beginning of the spectrum are discussed. The coherence length in a bent crystal appears to depend only on the crystal geometry and not on the electron or photon energies, which is essential for interpretation of the results. Estimates of non-dipole radiation and multiple scattering effects are given. The value for the crystal bending angle at which the dipole coherent bremsstrahlung theory holds best appears to be $\sim 10^{-4}\mathrm{rad}$.

description: We show the importance of the Voros product in defining a noncommutative Schwarzschild black hole. The corrected entropy/area-law is then computed in the tunneling formalism. Two types of corrections are considered; one, due to the effects of noncommutativity and the other, due to the effects of going beyond the semiclassical approximation. The leading correction to the semiclassical entropy/area-law is logarithmic and its coefficient involves the noncommutative parameter.

description: Fort McMurray has experienced significant environmental disruptions, raising concerns about chemical releases that affect the environment, particularly berries. This thesis explores the relationship between environmental factors and the nutritional quality of pin cherry (Prunus pensylvanica L.F.) and common blueberry (Vaccinium myrtilloides Michx) fruits and soil in Fort McMurray (reclaimed and natural lands). Samples were collected in August 2022 and analyzed for chemicals and quality variables. The results revealed concentration variations among samples, with hydrocarbons higher in reclaimed areas and blueberries than others and soil surpassing those in fruits. Copper and iron in fruits exceeded regulatory limits. A strong association between soil chemicals and alkylated hydrocarbons in fruits explained most differences. Soil trace elements and properties were primary environmental drivers, while hydrocarbons were secondary influencers, evident mainly in reclaimed berry environments. Antioxidant-focused nutritional quality in reclaimed berries was predominantly influenced by these key drivers in soil, requiring consistent monitoring.

description: We study a scenario that a U(1) hidden gaugino constitutes the dark matter in the Universe and decays into a lepton and slepton pair through a mixing with a U(1)B-L gaugino. We find that the dark-matter decay can account for the recent PAMELA and ATIC anomalies in the cosmic-ray positrons and electrons without an overproduction of antiprotons.
