description: In this paper, the phenomenon of low-threshold field emission of electrons from thin films of several metals (molybdenum, nickel, tungsten, titanium, and zirconium) is experimentally studied. The ability of island metal films to emit electrons at room temperature in a field with a macroscopic intensity of the order of units V /Î¼ is confirmed. A correlation was found between the emission properties of films and their morphology, namely, the presence of isolated metal Islands with a lateral size in the range of 20-50 nm and a few nanometers in height.
Analytical results connecting stellar structure parameters and extended reaction rates

description: Possible modification in the velocity distribution in the non-resonant reaction rates leads to an extended reaction rate probability integral. The closed form representation for these thermonuclear functions are used to obtain the stellar luminosity and neutrino emission rates. The composite parameter {C} that determines the standard nuclear reaction rate through the Maxwell-Boltzmann energy distribution is extended to {C}^* by the extended reaction rates through a more general distribution than the Maxwell-Boltzmann distribution. The new distribution is obtained by the pathway model introduced by Mathai in 2005 [Linear Algebra and Its Applications, 396, 317-328]. Simple analytic models considered by various authors are utilized for evaluating stellar luminosity and neutrino emission rates and are obtained in generalized special functions such as Meijer's G-function and Fox's H-function. The standard and extended non-resonant thermonuclear functions are compared by plotting them. Behavior of the new energy distribution, more general than Maxwell-Boltzmann is also studied.

description: This article extends the transnational history of Anzac by shifting the focus from Britain to the United States. It tells a history of Anzac in the United States, focused on New York and California, that shows how both Anzac Day and the broader language and iconography of “Anzac” has been core to the production of Australian community and identity in the United States from the 1920s until the 2020s. Over multiple generations, stateside Australians have reached to Anzac to enact their Australianness and build ties with fellow expatriates. As a result, Anzac has come to serve as a metonym for Australians and Australianness within the United States. At the same time, Anzac in the United States has indexed Australia’s shift from British to American empires. Once a British affair, it is now an annual event to renew the transpacific alliance.
A combined-methods study of the training and practice of Alberta's therapeutic massage bodywork providers

description: Background Therapeutic massage bodywork (TMB) therapies are commonly used by the public, nevertheless, research validating TMB is nascent. Practitioner variability may be affecting research outcomes. This study therefore describes and explores the relationship between therapist variables (e.g., training, practice focus) and clinical TMB experience, and the consequent implications for TMB research. Methods A combined methods design, consisting of a quantitative, population-based survey and qualitative interviews with practitioners trained in multiple therapies, was used to explore the training and practice of TMB practitioners in Alberta, Canada. Results Of the 5242 distributed surveys, 791 were returned (15.1%). The sample demographics did not significantly differ from other massage therapist study populations. Practitioners were trained in 77 distinct TMB therapies. Most practitioners (94.4%) were trained in two or more therapies, with a median of 8 and range of 40 therapies. Training programs varied widely in number and type of TMB components, training length, or both. Nineteen practitioners trained in multiple TMB therapies were interviewed. Participants reported greatly varying training backgrounds, resulting in practitioners learning and practicing unique combinations of therapy techniques. Moreover, all practitioners described addressing patients’ needs by providing individualized patient treatment based on a responsive feedback process throughout practice. Additionally, practitioners distrust TMB research results because of perceived and actual treatment provision differences between TMB clinical practice and TMB treatments used in research. Conclusions The training received, the number of therapies trained in, and the practice descriptors of TMB practitioners are all highly variable. Clinical experience and continuing education may further alter or enhance treatment techniques. Therefore, treatment provision and individualization are likely practitioner-specific. Practitioners surmise that clinical trials do not accommodate practitioner variability or treatment individualization, resulting in limited clinical application of TMB research. The high variability in training and experience between practitioners necessitates improved research reporting of practitioner qualifications and expertise, and the consequent impact on the results. TMB research designs need to accommodate the inherent individualization of clinical practice and capture relevant contextual outcomes. Knowledge translation of research results must address TMB practitioners’ perceived differences between TMB research treatments and TMB clinical practice.

description: Under the umbrella of the BioMedBridges project, fourteen research infrastructures in the biological, biomedical and environmental sciences developed commonly agreed principles of data management and sharing. The document makes key recommendations on how data management and sharing via the research infrastructures can be supported and encouraged:

	The RIs encourage data sharing and reuse and support the notion that public funders should encourage Open Access to data from publicly funded research where possible.
	Some data may only be shared under certain conditions and with appropriate safekeeping mechanisms in place, such as personally identifiable data, data subject to ethical or legal restrictions, or restrictions for intellectual property protection.
	To encourage data sharing, systematic reward and recognition mechanisms are necessary.
	Proposals for publicly funded research at RIs should include a data management plan concerning the deposition of data in long-term archives that addresses specific resources and activities (including standardisation of data production and curation/annotation).
	Funding for tools and activities connected to data deposition must be available.
	Systems, services and resources must be in place to facilitate straightforward data deposition by researchers, including support concerning the necessary data use agreements and consent forms for data with data protection or intellectual property requirements.
	Systems are also needed to capture and track data provenance and use.
	To ensure necessary trust by data providers or depositors, RIs must guarantee high standards of security and traceability.

description: Russia’s energy sector has changed dramatically over the past three decades and this study examines this change within the oil, gas, and nuclear sectors. Having inherited a state capitalist system after the fall of the Soviet Union, Russia’s bureaucracy now presides over an incredibly rich and deeply problematic energy economy. At its core, this is a study on institutionalized corruption and the behavior of corrupt elites. More specifically, it examines whether Russia can succeed within this context and what this may teach us on the nature of corrupt states and institutions.

description: A non-perturbative version of the BRST quartet mechanism in infrared Landau gauge QCD is proposed for transverse gluons and quarks. Based on the positivity violation for transverse gluons the content of the respective non-perturbative BRST quartet is derived. To identify the gluon's BRST-daughter and second parent state, a truncated Bethe-Salpeter equation for the gluon-(anti-)ghost bound state is investigated. We comment shortly on several equivalent forms of this equation. Repeating the same construction for quarks leads to a truncated Bethe-Salpeter equation for a fundamentally charged quark-(anti-)ghost bound state. It turns out that a cardinal input to this equation is given by the fully dressed quark-gluon vertex, and that it is indispensable to dress the quark-gluon vertex in this equation in order to obtain a consistent truncation.

Neurogenic Hypertension Mediated Mitochondrial Abnormality Leads to Cardiomyopathy: Contribution of UPRmt and Norepinephrine-miR-18a-5p-HIF-1a Axis
Creators: name: Nandi, Shyam Sundar
Publisher: name: figshare
Year: 2023
Subjects: Cardiology (incl. cardiovascular diseases)

description: Aims: Hypertension increases the risk of heart disease. Hallmark features of hypertensive heart disease is sympathoexcitation and cardiac mitochondrial abnormality. However, the molecular mechanisms for specifically neurally mediated mitochondrial abnormality and subsequent cardiac dysfunction are unclear. We hypothesized that enhanced sympatho-excitation to the heart elicits cardiac miR-18a-5p/HIF-1α and mitochondrial unfolded protein response (UPRmt) signaling that lead to mitochondrial abnormalities and consequent pathological cardiac remodeling. Methods and Results: Using a model of neurogenic hypertension (NG-HTN), induced by intracerebroventricular (ICV) infusion of Ang II (NG-HTN; 20 ng/min, 14 days, 0.5 μl/h, or Saline; Control, 0.9%) through osmotic mini-pumps in Sprague-Dawley rats (250–300 g), we attempted to identify a link between sympathoexcitation (norepinephrine; NE), miRNA and HIF-1α signaling and UPRmt to produce mitochondrial abnormalities resulting in cardiomyopathy. Cardiac remodeling, mitochondrial abnormality, and miRNA/HIF-1α signaling were assessed using histology, immunocytochemistry, electron microscopy, Western blotting or RT-qPCR. NG-HTN demonstrated increased sympatho-excitation with concomitant reduction in UPRmt, miRNA-18a-5p and increased level of HIF-1α in the heart. Our in silico analysis indicated that miR-18a-5p targets HIF-1α. Direct effects of NE on miRNA/HIF-1α signaling and mitochondrial abnormality examined using H9c2 rat cardiomyocytes showed NE reduces miR-18a-5p but increases HIF-1α. Electron microscopy revealed cardiac mitochondrial abnormality in NG-HTN, linked with hypertrophic cardiomyopathy and fibrosis. Mitochondrial unfolded protein response was decreased in NG-HTN indicating mitochondrial proteinopathy and proteotoxic stress, associated with increased mito-ROS and decreased mitochondrial membrane potential (ΔΨm), and oxidative phosphorylation. Further, there was reduced cardiac mitochondrial biogenesis and fusion, but increased mitochondrial fission, coupled with mitochondrial impaired TIM-TOM transport and UPRmt. Direct effects of NE on H9c2 rat cardiomyocytes also showed cardiomyocyte hypertrophy, increased mitochondrial ROS generation, and UPRmt corroborating the in vivo data. Conclusion: In conclusion, enhanced sympatho-excitation suppress miR-18a-5p/HIF-1α signaling and increased mitochondrial stress proteotoxicity, decreased UPRmt leading to decreased mitochondrial dynamics/OXPHOS/ΔΨm and ROS generation. Taken together, these results suggest that ROS induced mitochondrial transition pore opening activates pro-hypertrophy/fibrosis/inflammatory factors that induce pathological cardiac hypertrophy and fibrosis commonly observed in NG-HTN.

description: Gibbs measures are the main object of study in equilibrium statistical mechanics, and are used in many other contexts, including dynamical systems and ergodic theory, and spatial statistics. However, in a large number of natural instances one encounters measures that are not of Gibbsian form. We present here a number of examples of such non-Gibbsian measures, and discuss some of the underlying mathematical and physical issues to which they gave rise.

description: In this thesis, we introduce an algorithm to compute 6-dimensional totally-sewn neighbourly polytopes. We apply this algorithm to construct a class of semi-cyclic 6-polytopes, and give a complete description of their faces. We then confirm the Separation Conjecture for these semi-cyclic 6-polytopes. Next, we verify the X-ray Conjecture in the plane by showing that triangles are the only planar convex sets that cannot be X-rayed along two lines. We use this result to show that any 3-dimensional convex body exhibiting mirror symmetry also satisfies the X-ray conjecture.
Transboundary management of a fish stock under climate variability : the case of Pacific sardine in the California current ecosystem
Creators: name: Ishimura, Gakushi
Publisher: name: University of British Columbia
Year: 2010

description: The time variant/asymmetric distribution of a fish stock caused by ocean climate variability is one of the challenges that must be overcome to establish cooperative management of a transboundary fish stock. Pacific sardine (Sardinops sagax) exhibits extreme decadal variability in its abundance and geographic distribution that corresponds to water temperature regime shifts within the California Current Ecosystem. It is a transboundary fish stock and targeted by Mexican, American and Canadian fisheries, and the three countries do not currently have a cooperative management arrangement. This thesis explores the economic and conservation consequences of non-cooperative management, and the potential benefits of full/partial cooperative management of Pacific sardine, and studies the stability of cooperative management under ocean climate variability. The core of the thesis is presented in Chapters 2-4, with an introduction given in Chapter 1 and a conclusion in Chapter 5. Appendix A and B provide background information on Pacific sardine and the Pacific sardine fishery, respectively. Chapter 2 develops a three-agent bioeconomic framework to investigate the impact of ocean climate variability on stock abundance and geographic distribution. A game theoretic analysis was conducted to evaluate the conservation and economic benefits of various management strategies. The results show that under a regime of ocean climate variability, a country having a dominate share of the resource within its waters cannot achieve effective unilateral conservation for optimal economic benefits due to the actions of free-riders. Chapter 3 conducts simulations to evaluate the stability of full and partial cooperative management of Pacific sardine under various climate variability scenarios. The results show that in all scenarios, ocean climate variability is an obstacle to the formation of stable, fully-cooperative management of Pacific sardine fisheries as operated by the three countries. Chapter 4 estimates the cost of delaying cooperative management of this fishery, and how costs are incurred due to such delays. The results suggest that the cost of delaying cooperative management is significant for a country having a dominant share, while countries that have minor shares gain economic benefits from delaying cooperative management.

description: The role of elastic defects on the kinetics of 180-degree uncharged ferroelectric domain wall motion is explored using continuum time-dependent LGD equation with elastic dipole coupling. In one dimensional case, ripples, steps and oscillations of the domain wall velocity appear due to the wall-defect interactions. While the defects do not affect the limiting-wall velocity vs. field dependence, they result in the minimal threshold field required to activate the wall motions. The analytical expressions for the threshold field are derived and the latter is shown to be much smaller than the thermodynamic coercive field. The threshold field is linearly proportional to the concentration of defects and non-monotonically depends on the average distance between them. The obtained results provide the insight into the mesoscopic mechanism of the domain wall pinning by elastic defects in ferroelectrics.

The Impacts of Urbanization on Agricultural Sustainability in Palestine after the Construction of the Separation Wall: The Case of the City of Tulkarem

subject: Urban Planning

description: Agricultural land use in the urban environment is a hot topic in global urban sustainable development. However, most cities are losing agricultural areas to urbanization. Cities in Palestine and especially the city of Tulkarem have experienced rapid urbanization that is responsible for an increased demand for land. At the same time, city expansion is restricted due to the political situation and existence of the Separation Wall along the city’s west side. The squeeze of urban land results in loss of arable land for agriculture, degradation of ecosystems, and social changes within urban populations. A study to document the impacts of urbanization on agricultural land use with the existence of the Separation Wall and unstable political conditions is needed, and that was the purpose of this research. The study presented views of the urban planners, decision makers and farmers. Quantitative and qualitative case study methods were employed where interviews were conducted with the study participants. At the same time, land use maps for the city of Tulkarem before and after creation of the Separation Wall were compared using the GIS software package. The GIS analysis and maps were compatible with the information shared by the interview participants concluding that the study area has been subjected to land use change, especially urban expansion, which have caused serious threats to available agricultural land. Political instability, poor economic situation of the farmers, lack of support and guidance, land fragmentation and lack of laws and bylaws and interest in protecting agricultural lands were found to be the main factors that lead to agricultural land loss for urban uses in the city of Tulkarem. Further, the study found from the interviews that most of the land owners who sell for urban uses are expatriates, who live outside the country, and cannot come back or stay in Palestine due to the political and economical situation in Palestine. The impact of political factors, such as the Separation Wall and Oslo division of land to area A, B, and C, on this change in the Tulkarem area was clear. The political factors have direct and indirect impacts on Palestinian life conditions. The direct impact includes conversion of the land into Israeli structures, namely Separation Wall and C area as well as alienation of, or inaccessibility to, part or all of land, crops, water resources, and business assets, which caused wealth; income-generating and market access losses. The indirect impact is on the existing and future urban expansion, which will lead to losing more of the agricultural lands as there is no Palestinian control on the urban expansion directions and process.
How to remedy the eta-problem of SUSY GUT hybrid inflation via vector backreaction

description: It is shown that, in supergravity models of inflation where the gauge kinetic function of a gauge field is modulated by the inflaton, we can obtain a new inflationary attractor solution, in which the roll-over of the inflaton suffers additional impedance due to the vector field backreaction. As a result, directions of the scalar potential which, due to strong Kaehler corrections, become too steep and curved to normally support slow-roll inflation can now naturally do so. This solves the infamous eta-problem of inflation in supergravity and also keeps the spectral index of the curvature perturbation mildly red despite eta of order unity. This mechanism is applied to a model of hybrid inflation in supergravity with a generic Kaehler potential. The spectral index of the curvature perturbation is found to be 0.97 - 0.98, in excellent agreement with data. The gauge field can act as vector curvaton generating statistical anisotropy in the curvature perturbation. However, this anisotropy could be possibly observable only if the gauge coupling constant is unnaturally small.

description: We observed unexpected resonant response in [Fe/Cr]_(10) multilayers epitaxially grown on MgO(100) substrates which exists only when both ac current and dc magnetic field are simultaneously applied. The magnitude of the resonances is determined by the multilayer magnetization proving their intrinsic character. The reduction of interface epitaxy leads to non-linear dependence of the magnitude of resonances on the alternating current density. We speculate that the existence of the interface transition zone could facilitate the subatomic vibrations in thin metallic films and multilayers grown on bulk insulating substrates.

description: By using the Atiyah-Singer theorem through some similarities with the instanton and the anti-instanton moduli spaces, the dimension of the moduli space for two and four-dimensional BF theories valued in different background manifolds and gauge groups scenarios is determined. Additionally, we develop Dirac's canonical analysis for a four-dimensional modified BF theory, which reproduces the topological YM theory. This framework will allow us to understand the local symmetries, the constraints, the extended Hamiltonian and the extended action of the theory.

description: The present work employs network analysis to investigate the relationships between the great kings of the Near-East (Egypt, Mitanni, Hatti, Alashiya, Babylonia) and the mayors of the Syro-Palestinian region from the very end of the Amenhotep III reign to the beginning of Amenhotep IV-Akhenaten reign. Data are extracted from a sample of 83 letters from the el-Amarna corpus of correspondences discovered in Egypt (14th century B.C.). We focus on the distribution of information (actors and links) in the Amarna letters and how this distribution influences the shape of the egyptian king’s personnal network. Through a holistic approach, we highlight different groups of interactions and analyse their relationnal properties. Futhermore, we show which type of interaction is predominant according to each group. Observations suggest that trade flows monopolize the attention of the great kings who organize their close networks around these exchanges. On the other hand, the mayors of the Syro-Palestinian corridor are integrated into a network structured around warlike concerns. This structure is distorted by the rise of the Amurru in northern Lebanon, which leads to a polarization of relations towards two antagonists: Rib-Hadda, the mayor of Byblos and Abdi-Aširta, a local warlord. On an individual level, we analyse closely the strategies of the two opponents with the support of correlative analysis QAP. The study concludes by discussing possible developments based on this dataset.

Canine CAR T cell therapy for solid tumors

description: Adoptive cell transfer of chimeric antigen receptors (CAR) T cells has successfully targeted hematological malignancies in human patients. However, unpredicted side effects experienced after injection of the CAR T cells suggests the need for an optimal predictive preclinical animal model. Dogs have intact immune systems and develop solid tumors spontaneously with similar morphology and genetics to humans. I hypothesize that generating CAR T cells for dogs will closely mimic human patients' outcomes, thus providing new understandings of the safety of this immunotherapy. In addition to the dog as a preclinical model, we propose using a universal CAR T cell to overcome various tumor-related immunosuppressive challenges and control the killing of the target cells. To achieve this, we established methods for activating and expanding canine T cells to a clinically relevant scale. Then, we expressed a second-generation anti-FITC-8-41BB-ζ CAR T cell via lentiviral transduction. In the presence of the correct low-molecular-weight bispecific adapter, we showed in-vitro CAR-mediated function. Our results proved that it is feasible to generate functional canine anti-FITC-8-BB-ζ CAR T cells for therapy.

description: Sense of place is an impression of setting that emerges through one’s experiences within. Tied to phenomenology, the concept that knowledge is transferred through direct experience, place is considered important in community settings as it helps individuals come to know the cultural landscape; it’s place-identity, more fully. Community pathway systems provide a beneficial platform for activity in community settings , providing access to the environment and the intrinsic cultural symbols within, that support place-identity knowledge. As urban centers continue to grow demographically and spatially, the maintenance of traditional place-identity is an increasingly important area of study. By identifying and drawing on the cultural themes and narratives that a community values most, and integrating these into a place-centric experience, knowledge of traditional character and heritage can be impressed and thus supported for the future. This thesis explores and outlines a place-making design methodology that, in application, will enhance the experience in community pathway systems. The objective of this study is to establish a design model that will affect sense of place and leverage its phenomenological potential to transfer the knowledge upon which community place-identity is based. In addition to supporting and heightening the place-experience(s) within these settings, this model will result in a unique pathway environment which can bolster a community’s image, both for resident and visitor alike.
q-Deformation of the AdS5 x S5 Superstring S-matrix and its Relativistic Limit

description: A set of four factorizable non-relativistic S-matrices for a multiplet of fundamental particles are defined based on the R-matrix of the quantum group deformation of the centrally extended superalgebra su(2|2). The S-matrices are a function of two independent couplings g and q=exp(iπ/k). The main result is to find the scalar factor, or dressing phase, which ensures that the unitarity and crossing equations are satisfied. For generic (g,k), the S-matrices are branched functions on a product of rapidity tori. In the limit k->infinity, one of them is identified with the S-matrix describing the magnon excitations on the string world sheet in AdS5 x S5, while another is the mirror S-matrix that is needed for the TBA. In the g->infinity limit, the rapidity torus degenerates, the branch points disappear and the S-matrices become meromorphic functions, as required by relativistic S-matrix theory. However, it is only the mirror S-matrix which satisfies the correct relativistic crossing equation. The mirror S-matrix in the relativistic limit is then closely related to that of the semi-symmetric space sine-Gordon theory obtained from the string theory by the Pohlmeyer reduction, but has anti-symmetric rather than symmetric bound states. The interpolating S-matrix realizes at the quantum level the fact that at the classical level the two theories correspond to different limits of a one-parameter family of symplectic structures of the same integrable system.

Transport of Ultra-Fine Particles in Suspension through Structured Porous Media
Creators: name: Sajjadiani, Simin
Publisher: name: Graduate Studies
Year: 2014
Subjects: Engineering--Chemical

description: Transport of suspensions of ultrafine and colloidal particles through porous structures is a common occurrence. Commercial filters are examples of media usually consisting of randomly-oriented fibers in layers to capture large particles. Aquifers, fixed-bed catalytic reactors and hydrocarbon reservoirs are granular formations with high spatial interconnectivity that allow small particles to be carried with the percolating fluid. Often, of interest is how far the particles would penetrate into the structure on advective streams. Experiments were conducted to record the paths of nanoparticles in dilute suspensions through micromodels of porous media. The particles are primarily propelled by hydrodynamic forces through regular arrays of cylindrical posts arranged between two closely-spaced flat surfaces. The setup consisted of the test cell, an inverted microscope, a high speed camera, a data processor, a precise actuating syringe pump, and spherical silica particles (0.2, 0.5 and 1.5 µm diameter) that encapsulated a fluorescent dye. The particle trajectories deviated from the streamlines for particle-free fluids through the domain, and the slip condition was prevalent in an environment in which the fluid velocity field and the particle motion affected each other. The trajectories show evidence of Brownian motion more significantly for the smaller particles that were also dispersed faster through the less porous media. Suspensions were dispersed in the Hele-Shaw section primarily by advection, and the extent was directly correlated to the flow rates and inversely correlated to the particle diameter, the solid volume fraction and the concentration. Axial dispersion was slower in the micro-models than in the Hele-Shaw cell.

The case of hard-core bosons is considered and pseudospin formalism is used. Phase diagrams are built in the plain of chemical potential of the bosons-bosonic hopping parameter. It is shown that in the case of anisotropic hopping, the region of the supersolid phase existence is possible for a smaller parameter space.

description: In this study, the influence of levan on the phase behavior and the thermally induced gelation of the mixed β-lactoglobulin—levan gels as a function of polymer content, molecular weight and ionic strength was characterized. For this purpose, rheology was used to study the mechanical properties of the gels and the water binding of the network structure was investigated by time domain nuclear magnetic resonance. Phase behavior and network type were analyzed by optical observation and electron microscopy. Levan enhanced the aggregation and gel formation of β-lg due to segregative forces between the polymer species. Segregation was caused by the excluded volume effect and was more pronounced at lower ionic strength, higher levan contents and higher levan molecular weights. The presence of levan increased the water binding of the gel networks. However, this effect decreased with increasing levan content. At high ionic strength and high levan content, phase separated gels were formed. While segregative forces enhanced network formation, and therefore, increased the gel strength of mixed gels at low ionic strength, levan had also antagonistic effects on the network formation at high ionic strength and high polymer contents.
