description: Introduction: Chronic kidney disease prevalence has been increasing worldwide, with an increasing need to deliver an effective treatment. During the first months of the coronavirus disease 2019 (COVID-19) pandemic healthcare systems around the world were under stress. Therefore, the aim of this study is to report a single center experience with arteriovenous fistula (AVF) creation while also evaluating the impact of COVID-19. Methods: Procedures for AVF creation in a tertiary hospital between March 2017 and December 2020 were included in this study and their case records were retrospectively analyzed and data retrieved. Results: A total of 582 procedures were performed and a total of 568 accesses were created (506 being made pre-COVID onset and 62 post-COVID onset). The period between the referral to the vascular surgery consultation was significantly longer for the COVID group [18 (23) days vs 28 (44) days; p<0,001] while the period between the consultation to the surgery was significantly shorter [76 (77) days vs 40 (57) days; p<0,001]. This resulted in significantly less time between referral to surgery in the COVID group [103 (77) days vs 88 (55) days; p=0,008]. Conclusion: The ability of hospitals to adapt their resources was paramount to mitigate COVID impact. In the institution where the study took place, the time from referral to consultation was increased significantly during the first months of COVID but the time from consultation to surgery was significantly reduced. Overall, these results show that there was a successful effort to expedite the creation of a vascular access.

A Variational Principle for Discrete Integrable Systems

description: For integrable systems in the sense of multidimensional consistency (MDC) we can consider the Lagrangian as a form, which is closed on solutions of the equations of motion. For 2-dimensional systems, described by partial difference equations with two independent variables, MDC allows us to define an action on arbitrary 2-dimensional surfaces embedded in a higher dimensional space of independent variables, where the action is not only a functional of the field variables but also the choice of surface. It is then natural to propose that the system should be derived from a variational principle which includes not only variations with respect to the dependent variables, but also with respect to variations of the surface in the space of independent variables. Here we derive the resulting system of generalized Euler-Lagrange equations arising from that principle. We treat the case where the equations are 2 dimensional (but which due to MDC can be consistently embedded in higher-dimensional space), and show that they can be integrated to yield relations of quadrilateral type. We also derive the extended set of Euler-Lagrange equations for 3-dimensional systems, i.e., those for equations with 3 independent variables. The emerging point of view from this study is that the variational principle can be considered as the set of equations not only encoding the equations of motion but as the defining equations for the Lagrangians themselves.

One application (if not the most significant at the present) of Privacy Enhancing Technology is anonymous Web surfing. While weak protection can be achieved by simple proxy solutions, strong anonymity needs more effort: Systems like JAP and TOR are based on the idea of the "mix network" introduced by David Chaum in 1981. The talk presents selected basic privacy enhancing techniques, available practical solutions and gives some insights into the operation of the JAP Anonymizer.

description: For each function on bit strings, its restriction to bit strings of any given length can be computed by a finite instruction sequence that contains only instructions to set and get the content of Boolean registers, forward jump instructions, and a termination instruction. We describe instruction sequences of this kind that compute the function on bit strings that models multiplication on natural numbers less than $2^N$ with respect to their binary representation by bit strings of length $N$, for a fixed but arbitrary $N > 0$, according to the long multiplication algorithm and the Karatsuba multiplication algorithm. We find among other things that the instruction sequence expressing the former algorithm is longer than the one expressing the latter algorithm only if the length of the bit strings involved is greater than $2^8$. We also go into the use of an instruction sequence with backward jump instructions for expressing the long multiplication algorithm. This leads to an instruction sequence that it is shorter than the other two if the length of the bit strings involved is greater than $2$.

description: Let $X$ be a smooth manifold belonging to one of these three collections: acyclic manifolds (compact or not, possibly with boundary), compact connected manifolds (possibly with boundary) with nonzero Euler characteristic, integral homology spheres. We prove that $Diff(X)$ is Jordan. This means that there exists a constant $C$ such that any finite subgroup $G$ of $Diff(X)$ has an abelian subgroup whose index in $G$ is at most $C$. Using a result of Randall and Petrie we deduce that the automorphism groups of connected, non necessarily compact, smooth real affine varieties with nonzero Euler characteristic are Jordan.

description: Although Cushing's Syndrome (CS) is usually caused by pituitary/adrenal adenomas, in the remaining few cases, Adrenocorticotrophic hormone (ACTH) is secreted by extrapituitary neuroendocrine tumors (NET). In typical pulmonary / bronchial carcinoid tumors leading to ectopic ACTH syndrome (EAS). The main principle of treatment is the localization of the ACTH-secreting tumor and its surgical removal. In this case report, we aimed to present two typical carcinoid cases, whose ACTH and cortisol levels returned to normal after lung surgery for ectopic ACTH. One of the cases, a 32-year-old female patient with CS symptoms and signs, was referred to our department after detecting a lesion in the left lower lobe in the thorax CT, which did not show an obvious focus on cranial MRI. The other patient, a 36-year-old male, had previously undergone adrenalectomy for Cushing's syndrome and was admitted to the emergency department due to adrenal insufficiency. The lesion seen in the right lower lobe on thorax CT was evaluated as an ectopic ACTH focus. After the tumors of the patients were resected according to surgical principles, CS clinic regressed, and ACTH and cortisol values returned to normal. Pathological examinations of the surgically resected tumors were reported as typical carcinoid. With surgically removed typical carcinoids tumors, excellent longterm survival results can be achieved and hypercortisolism can be controlled.

description: Objectives: In recent years, a correlation between prognosis of various cancers and inflammation has been emphasized in many studies. Uric acid which is a purine metabolite is one of the serum inflammation markers. Albumin is a major component of serum protein and it is used as a parameter reflecting nutritional status and cancer aggressiveness. Here, we have investigated whether preoperative serum uric acid levels, albumin levels, and uric acid to albumin ratio predict lymph node metastasis in non-small cell lung cancer treated surgically by VATS. Methods: The medical records of patients underwent VATS lobectomy-segmentectomy for non-small cell lung cancer between January 2015 and December 2020, were reviewed retrospectively. Cut-off values of preoperative serum uric acid, albumin and uric acid to albumin ratio were determined by Receiver Operating Characteristics (ROC) analysis. Groups with and without lymph node metastasis were created according to hilar and/or mediastinal lymph node metastasis. In addition, high and low groups were created according to preoperative uric acid levels and uric acid to albumin ratio. Pearson chi-square test was used investigate whether any significant correlation between the groups. Results: A total of 115 patients were included in the study. Lymph node metastasis in N1 and N2 stations was detected in 11 and 18 patients, respectively. Cut-off values for uric acid and uric acid to albumin ratio were 5.97 mg/dL and 1.28x10-3, respectively. There was a statistically significant correlation between lymph node metastasis and high uric acid levels (p=0.008, OR: 3.2) and high uric acid to albumin ratio (p=0.03, OR: 2.6). Conclusion: Preoperative serum uric acid and uric acid to albumin ratio can predict the lymph node metastasis in non-small cell lung cancer treated surgically by video assisted thoracic surgery.

description: Epithelioid hemangioma (EH) is an uncommon benign vascular lesion usually present as subcutaneous nodules in the head and neck area. Sometimes, these lesions can occur in the peripheral arteries, and when they do, they can be mistaken for aneurysmal dilatations of that respective vessel. We report a case of a 43-year-old male who underwent surgical recession of a radial aneurysm, which after anatomopathological examination, revealed an EH.

description: The open educational resources (OER) movement is an emerging trend in higher education contexts, primarily due to the ubiquitous use of technology and access to the internet. This literature review focuses on the concept of OER, its essential definitions, its potential benefits, its open nature, and various aspects of adoption. The research findings indicate that the OER movement has not expanded fully into educational sectors, and the level of faculty and student awareness is quite low. The research also reveals that the current status of OER adoption in educational sectors is minimal. Additionally, OER adoption has encountered several obstacles; potential users have difficulty finding the proper OER materials, and there are quality control issues with resources. However, students saved a significant amount of money when OER replaced traditional textbooks. Many critical issues related to OER adoption must be resolved, and others may arise as more faculty and students begin to use these resources.

description: Peripheral arterial disease (PAD), abdominal aortic aneurysm (AAA) and chronic mesenteric ischaemia (CMI) are vascular diseases uncommonly observed in the same patient, especially when treatment is required. This case report illustrates a patient requiring mesenteric revascularization due to CMI. A long flush occlusion of the superior mesenteric artery (SMA) precluded endovascular revascularization. Therefore, we performed a retrograde bypass from the right common iliac artery (CIA) to the SMA. On the 6-month follow-up, the patient developed right limb ischemia despite the absence of intestinal angina. CT angiography revealed CIA occlusion, bypass patency through hypogastric retrograde filling and modest growth of a AAA. Due to the presence of contralateral CIA lesions and to achieve durable revascularization, we opted to perform a AAA repair with an aorto-uni-iliac endograft followed by a femorofemoral crossover bypass. This achieved AAA’s repair, lower limb revascularization, and a suitable and durable inflow to the mesenteric bypass.

description: We extend the covariant color-kinematics duality introduced by Cheung and Mangan to effective field theories. We focus in particular on relations between the effective field theories of gluons only and of gluons coupled to bi-adjoint scalars. Maps are established between their respective equations of motion and between their tree-level scattering amplitudes. An additional rule for the replacement of flavor structures by kinematic factors realizes the map between higher-derivative amplitudes. As an example of new relations, the pure-gluon amplitudes of mass dimension up to eight, featuring insertions of the $F^3$ and $F^4$ operators which satisfy the traditional color-kinematics duality, can be generated at all multiplicities from just renormalizable amplitudes of gluons and bi-adjoint scalars. We also obtain closed-form expressions for the kinematic numerators of the dimension-six gluon effective field theory, which are valid in $D$ space-time dimensions. Finally, we find strong evidence that this extended covariant color-kinematics duality relates the $(DF)^2+$YM$(+\phi^3)$ theories which, at low energies, generate infinite towers of operators satisfying the traditional color-kinematics duality, beyond aforementioned $F^3$ and $F^4$ ones.

description: Extant ray-finned fishes (Actinopterygii) dominate marine and freshwater environments, yet spatio-temporal diversity dynamics following their origin in the Palaeozoic are poorly understood. Previous studies investigate face-value patterns of richness, with only qualitative assessment of biases acting on the Palaeozoic actinopterygian fossil record. Here, we investigate palaeogeographic trends, reconstruct local richness and apply richness estimation techniques to a recently assembled occurrence database for Palaeozoic ray-finned fishes. We identify substantial fossil record biases, such as geographical bias in sampling centred around Europe and North America. Similarly, estimates of diversity are skewed by extreme unevenness in the occurrence distributions, reflecting historical biases in sampling and taxonomic practices, to the extent that evenness has an overriding effect on diversity estimates. Other than a genuine rise in diversity in the Tournaisian following the end-Devonian mass extinction, diversity estimates for Palaeozoic actinopterygians appear to lack biological signal, are heavily biased and are highly dependent on sampling. Increased sampling of poorly represented regions and expanding sampling beyond the literature to include museum collection data will be critical in obtaining accurate estimates of Palaeozoic actinopterygian diversity. In conjunction, applying diversity estimation techniques to well-sampled regional subsets of the ‘global’ dataset may identify accurate local diversity trends.

description: One of the most important practical realizations of the fundamentals of quantum mechanics is continuous-variable quantum key distribution (CVQKD). Here we propose the adaptive multicarrier quadrature division-multiuser quadrature allocation (AMQD-MQA) multiple access technique for continuous-variable quantum key distribution. The MQA scheme is based on the AMQD modulation, which granulates the inputs of the users into Gaussian subcarrier continuous-variables (CVs). In an AMQD-MQA multiple access scenario, the simultaneous reliable transmission of the users is handled by the dynamic allocation of the Gaussian subcarrier CVs. We propose two different settings of AMQD-MQA for multiple input-multiple output communication. We introduce a rate-selection strategy that tunes the modulation variances and allocates adaptively the quadratures of the users over the sub-channels. We also prove the rate formulas if only partial channel side information is available for the users of the sub-channel conditions. We show a technique for the compensation of a nonideal Gaussian input modulation, which allows the users to overwhelm the modulation imperfections to reach optimal capacity-achieving communication over the Gaussian sub-channels. We investigate the diversity amplification of the sub-channel transmittance coefficients and reveal that a strong diversity can be exploited by opportunistic Gaussian modulation.

Obesity and C-Reactive Protein, Immunoglobulins, and Lipids
Creators: name: Alsufyani, Amal Abdulaziz
Publisher: name: Journal of Mason Graduate Research
Year: 2016

description: Obesity has been increasing in rich oil producing countries, such as Saudi Arabia, for the last few decades. Weight above the healthy level is suggested to interfere with normal immune function, affecting both innate and acquired immune responses. This study aimed to determine the relationship between increased weight and serum concentrations of C-reactive protein (CRP), Immunoglobulin (Ig)G, IgM, IgA, and the lipid profile. One hundred and nineteen randomly chosen Saudi female college students were assessed for their weight status using the body mass index (BMI) and the waist-to-hip ratio (WHR). Findings show that as the BMI and WHR increase, the CRP levels increase highly significantly compared to the controls. IgA levels also increase significantly as the BMI and WHR increase. Conversely, both IgG and IgM levels are not affected by the BMI or WHR. As for the lipid profile, cholesterol concentrations rise highly significantly as the WHR increases, but it is not affected by the BMI. Triacylglycerols and LDL levels increase highly significantly, while HDL decreases highly significantly in association with BMI and WHR increase. Multiple comparisons between the BMI and WHR groups were also investigated. In conclusion, increasing weight and obesity is correlated with an increase in CRP concentration, suggesting the presence of a state of harmful unspecific inflammation. The observed increase in IgA with the increase of weight and obesity agrees with findings by other researchers of increased respiratory infections in obese individuals. Finally, it is also concluded that overweight and obesity are associated with an unfavorable lipid profile, which is known to be detrimental to health and the immune system.

description: We consider the problem of deriving an explicit approximate solution of the nonlinear power equations that describe a balanced power distribution network. We give sufficient conditions for the existence of a practical solution to the power flow equations, and we propose an approximation that is linear in the active and reactive power demands of the PQ buses. For this approximation, which is valid for generic power line impedances and grid topology, we derive a bound on the approximation error as a function of the grid parameters. We illustrate the quality of the approximation via simulations, we show how it can also model the presence of voltage controlled (PV) buses, and we discuss how it generalizes the DC power flow model to lossy networks.

Modeling the Propensity to Default on Microloans in Mali, Africa

description: Microfinance is a global phenomenon that is focused on sustainable poverty alleviation.Â  By providing people in developing countries with the capital to sustain themselves and an educational background on which to build their futures, microfinance institutions (MFIs) have given the poor an opportunity to get out of poverty.Â  For the purposes of this study, a specific MFI in Mali Africa was utilized to model the propensity for micro-borrowers to default on their loans.Â  Using the MFIâ€™s historical data on each of their loans, this study models the repayment percentage of individual loans, contingent upon qualitative and quantitative factors.Â  Employing an Ordinary Least Squares Model I am able to analyze how each independent factor influences default rates.Â  I also harness fuzzy analysis to group together factors that contribute to high default rates.Â  I hypothesize that high default rates were encouraged by a longer time between payments, a large initial loan size, business development in investment heavy industries, and starting a business in a hostile market environment.Â  By utilizing these results, the MFI can optimize its loan repayment success by targeting specific borrowers and modifying their loan structure. The purpose of this study is to provide the Mali MFI with tangible results that they can utilize to increase their loaning effectiveness.Â  This model is important because microfinance is a relatively new field and 3it seeks to improve the Mali MFIâ€™s poverty alleviating capacity.Â Â

description: Let $X$ be an abelian variety defined over an algebraically closed field $k$. We consider theta groups associated to \emph{simple semi-homogenous vector bundles of separable type} on $X$. We determine the structure and representation theory of these groups. In doing so we relate work of Mumford, Mukai, and Umemura. We also consider adelic theta groups associated to line bundles on $X$. After reviewing Mumford's construction of these groups we determine functorial properties which they enjoy and then realize the Neron-Severi group of $X$ as a subgroup of the cohomology group $\H^2(\V(X); k^\times)$.

Coral Reefs: Challenges, Opportunities and Evolutionary Strategies for Surviving Climate Change in the Caribbean
Creators: name: Mahabir, Ron
Publisher: name: Journal of Mason Graduate Research
Year: 2016

description: Coral reefs are some one of the most diverse marine ecosystems on Earth. They are renowned hotspots of species biodiversity and provide home to a large array of marine plants and animals. Over the past 100 years in many tropical regions sea surface temperatures have increased by almost 1Â°C and are currently increasing at about 1â€“2Â°C per century. Corals have very specific thermal thresholds beyond which their temperature sensitive symbiot Zooxanthellae becomes affected and causes corals to bleach. Mass bleaching has already caused significant losses to live coral in many parts of the world. This paper looks at the key role that temperature plays in affecting the health and spatial distribution of coral in the Caribbean.

description: A holographic model of QCD in the limit of large number of colors, $N_c$, and massless fermion flavors, $N_f$, but constant ratio $x_f=N_f/N_c$ is analyzed at finite temperature and chemical potential. The five dimensional gravity model contains three bulk fields: a scalar dilaton sourcing ${\rm Tr}F^2$, a scalar tachyon dual to $\bar qq$ and a 4-vector dual to the baryon current $\bar q γ^μ q$. The main result is the $μ,T$ phase diagram of the holographic theory. A first order deconfining transition along $T_h(μ)$ and a chiral transition at $T_χ(μ)>T_h(μ)$ are found. The chiral transition is of second order for all $μ$. The dependence of thermodynamical quantities including the speed of sound and susceptibilities on the chemical potential and temperature is computed. A new quantum critical regime is found at zero temperature and finite chemical potential. It is controlled by an AdS$_2\times R^3$ geometry and displays semi-local criticality.

Media Coverage of the Arctic National Wildlife Refuge Drilling Controversy

Publisher: name: Journal of Mason Graduate Research

description: Protected areas are often subject to legal changes that allow natural resource extraction to occur within their boundaries. It is important to understand how the media covers these legal changes in order to inform science communication, environmental policy, and practice. As a case study, the oil drilling controversy in the Arctic National Wildlife Refuge (ANWR), the largest protected area in the United States, was examined. ANWR contains both environmental and potential economic value, including billions of barrels of oil. Controversy over whether to drill in the 1002 region of ANWR has been ongoing since the late 1970s and has been covered extensively in the media. A content analysis of media coverage of US national and Alaskan local newspapers was conducted for 100 news articles. Contrary to expectations, it was found that on average, media coverage tended to focus more on reasons to oppose drilling. When comparing local and national sources, it was found that local news articles also focused more on opposition to drilling. Arguments against drilling included risk of oil spills and other damage to wildlife and the environment, native Eskimo perspectives, and uncertainty about the amount and value of oil in ANWR. This analysis may inform future studies on environmental controversies and public land, especially related to the influence of the media on political decisions.

Multi-agent Inverse Reinforcement Learning for Two-person Zero-sum Games

description: The focus of this paper is a Bayesian framework for solving a class of problems termed multi-agent inverse reinforcement learning (MIRL). Compared to the well-known inverse reinforcement learning (IRL) problem, MIRL is formalized in the context of stochastic games, which generalize Markov decision processes to game theoretic scenarios. We establish a theoretical foundation for competitive two-agent zero-sum MIRL problems and propose a Bayesian solution approach in which the generative model is based on an assumption that the two agents follow a minimax bi-policy. Numerical results are presented comparing the Bayesian MIRL method with two existing methods in the context of an abstract soccer game. Investigation centers on relationships between the extent of prior information and the quality of learned rewards. Results suggest that covariance structure is more important than mean value in reward priors.
Do Grape Growers Cluster?  A Study of Virginia Winery Locations between 1971 and 2015

description: The growing demand for wine presents opportunities for the expansion of viticulture into new regions.Â  While the effect of climate and terrain upon the spatial distribution of wine grape (vitis vinifera) cultivation have been closely studied, economic factors such as the presence of local knowledge, tourist visitation patterns, and local investment and support also exhibit a strong influence upon where wineries open.Â  After examining the spatio-temporal patterns of winery openings in Virginia from 1976-2015 there is a strong trend towards increased spatial clustering as the wine region develops, with the most pronounced clusters being associated with counties where agribusiness has local support.Â  This pattern may offer local planners in other developing wine regions guidance for their zoning and developing policies to support a budding wine industry.

Exploration of Local Sea Level Rise Planning Public Perceptions
Creators: name: Carpenter, Adam Thomas
Publisher: name: Journal of Mason Graduate Research
Year: 2019

description: Sea level rise (SLR) is a potentially destructive phenomenon to coastal communities, despite uncertainties surrounding its extent, timing, and impacts. Forces driving SLR include climate change and geologic factors, globally and locally. Information available to communities preparing for SLR will likely never be perfect, given the difficulty of planning through uncertain global projections and assessing local conditions. Communities will need to develop SLR plans despite uncertainties, balancing factors such as determining the scope of a plan, assessing funding options, and identifying conflict resolution methods. This study describes a survey assessing the range of public preferences on these three planning factors. Key findings include that public engagement may be effective for overcoming local conflict, that too much focus on government intervention could be divisive, and that there are a wide variety of palatable methods to fund planning and implementation of those plans. This research informs local planning to reduce SLR risks.

description: Based on 33 interviews conducted in three different cities in Brazil (Sao Paulo, Salvador de Bahia, and Rio de Janeiro), this article explored the narratives of identity and social consciousness of Afro-Brazilians. The research aimed to understand how these communities have created a sense of self as well as their position in the Brazilian society. Moreover, it intended to explore their connection to Africa, the land of their ancestors, as we as the impact of the Brazilian Racial Democracy politics on their social and political identities. In a series of interviews and field work, I examined the different narratives and stories of identity, cultural affiliations, and social consciousness told by Afro-Brazilians. In the current political and economic instabilities, race and poverty are becoming major factors that influence the Brazilian social structures and problematized the different groups’ sense of selves and construction of meaning-making.
