description: Cognitive decline leading to dementia represents a global health burden. In the absence of targeted pharmacotherapy, lifestyle approaches remain the best option for slowing the onset of dementia. However, older adults spend very little time doing moderate to vigorous exercise and spend a majority of time in sedentary behavior. Sedentary behavior has been linked to poor glycemic control and increased risk of all-cause mortality. Here, we explore a potential link between sedentary behavior and brain health. We highlight the role of glycemic control in maintaining brain function and suggest that reducing and replacing sedentary behavior with intermittent light-intensity physical activity may protect against cognitive decline by reducing glycemic variability. Given that older adults find it difficult to achieve current exercise recommendations, this may be an additional practical strategy. However, more research is needed to understand the impact of poor glycemic control on brain function and whether practical interventions aimed at reducing and replacing sedentary behavior with intermittent light intensity physical activity can help slow cognitive decline.

description: The active substance of turmeric rhizome (curcumin) was extracted and identified with TLC and NMR. To evaluate the antioxidant efficiency of different concentrations of curcumin (120, 160 and 200 ppm) compared with tert-butylhydroquinone (TBHQ) (120 ppm) and α-tocopherol (200 ppm) at two different temperatures (25°C and 55°C) under dark and light conditions during 90 days, the soybean oil with no added antioxidant was used as a food model, and its fatty acids profile was determined by GC. Results indicated that increasing concentration of curcumin leads to significantly decreased oxidation rates. The soybean oil containing curcumin at 25°C in darkness with the lowest rate of increased peroxide value indicated the same antioxidant activity with α-tocopherol and TBHQ. Moreover, the results of acid value and iodine value indicated that samples with curcumin were more effective in preventing oxidation at both temperatures compared with control. However, light did not have any significant effect.

description: Excerpts from the report: The Bison 2014 study was conducted by the National Animal Health Monitoring System (NAHMS) with assistance from the National Agricultural Statistics Service (NASS). NAHMS is a nonregulatory program within the USDA Animal and Plant Health Inspection Service (APHIS) that gathers and disseminates animal health information. NAHMS is designed to help meet the Nation’s animal health information needs. The Bison 2014 study is the first time that NAHMS has conducted a survey of the U.S. ranched-bison industry. The study was designed and conducted in response to a request from the National Bison Association to do an epidemiological investigation of Mycoplasma bovis in bison. It was determined that the first step was to conduct a study to develop baseline information about the bison industry and the health of ranched bison. The purpose of the Bison 2014 study was to compile the most-needed information about the industry with regard to animal health and production management. To meet these information needs, the Bison 2014 study had the following objectives: • Provide a baseline description of the U.S. bison industry, including basic characteristics of operations, such as inventory, size, and type. • Describe current U.S. bison industry production practices and challenges, including identification, confinement and handling, animal care, and disease testing. • Describe health management and biosecurity practices important for the productivity and health of ranched bison. • Describe producer-reported occurrence of select health problems and evaluate potentially associated risk factors.
description: Acknowledgments: The Bison 2014 study was a cooperative effort between two U.S. Department of Agriculture (USDA) agencies: the National Agricultural Statistics Service (NASS) and Veterinary Services’ National Animal Health Monitoring System (NAHMS) within the Animal and Plant Health Inspection Service (APHIS). We would like to thank the NASS for allowing use of its list frame and mailing questionnaires to bison producers. We also especially thank the bison producers whose voluntary efforts made the Bison 2014 study possible. Finally, we thank the National Bison Association for its instrumental help in promoting the study and reviewing the questionnaire and report.

description: CsTaWO6 is a typical AMWO6-type compound and the photocatalysis of the pure and doped phases has been extensively studied experimentally. In this work, the electronic structures of sulphur (S) and nitrogen (N) co-doped CsTaWO6 have been studied in the framework of density functional theory, in particular the S/N co-doping effect has been investigated. It is found that, (i) S/N co-dopants prefer to be separated; (ii) middle-gap states are introduced by Nsingle bond and S-dopant at the edges of valence band and conduction band; and (iii) Co-doping not only narrows the band gap, but also promotes the separation of photo-excited electrons and holes. Feature (iii) has been identified as a key reason why S/N co-doped CsTaWO6 is more efficient in photocatalytic water-splitting. A general doping strategy has been further suggested: co-dopants which can dominate the frontier states and favour to be separated can offer excellent photocatalysis performance.

Enhancements to solving constraints written as imperative predicates

description: Modern software systems rely on automated testing and reliability techniques to detect bugs during development and to make the system resilient to runtime failures. Logical constraints that characterize properties of software components lie at the heart of many such techniques. Hence, improving the effectiveness of constraint solvers has been a continuous endeavor. Our focus is the Korat solver, which introduced a backtracking search algorithm to enumerate all object graphs that satisfy user given constraints (provided as a runnable check using an imperative language) within user given bounds. Korat has been applied to various applications including bounded exhaustive testing, constraint-based data structure repair, and model counting. While prior work explored various optimizations to enhance the performance and usability of Korat, scalability continues to remain a key challenge and applicability remains rather limited. Our work makes a threefold contribution. First, we introduce a new approach for constraint-based bounded exhaustive testing that is extension-aware and can re-use the test structures generated for a software component to speed up generating tests for an extended variant of that component that adds new fields, new constraints, or new bounds. Second, we propose a data structure repair technique by adapting the Korat search. Our technique succinctly memoizes the Korat search in tandem with a data structure repair to optimize future repairs of similar erroneous data structures that overlap in search. Third, we extend Korat-API, a framework that introduced a programmatic API for constraint-solving using Korat, by proposing new APIs and pruning mechanisms for testing and reliability applications. In particular, we introduce APIs to support constraint prioritization and Parallel Korat with memoization for generating tests, and we propose new approaches, namely incremental model counting and finer-grained control on bounds to optimize using Korat as a backend model counter for software reliability analysis. We share our algorithms and data structures that enable them, and report our experimental evaluation that shows the effectiveness of our new approaches. We believe this work opens a promising new direction to optimize solving constraints that are written as imperative predicates and further facilitate the usability of Korat in various testing and reliability applications.
Importance of stent-graft design for aortic arch aneurysm repair

description: Aneurysm of the aorta is currently treated by open surgical repair or endovascular repair. However, when the aneurysm occurs in regions between the aortic arch and proximal descending aorta, it can be a complex pathology to treat due to its intricate geometry. When complex aortic aneurysms are treated with the conventional procedures, some of the patients present with significant post-operative complications and high mortality rate. Consequently, a clinically driven hybrid innovation known as the frozen elephant trunk procedure was introduced to treat complex aortic aneurysms. Although this procedure significantly reduces mortality rate and operating time, it is still associated with complications such as endoleaks, spinal cord ischemia, renal failure and stroke. Some of these complications are consequences of a mismatch in the biomechanical behaviour of the stent-graft device and the aorta. Research on complex aneurysm repair tended to focus more on the surgical procedure than the stent-graft design. Current stent-graft devices are suitable for straight vessels. However, when used to treat aortic aneurysm with complex geometry, these devices are ineffective in restoring the normal biological and biomechanical function of the aorta. A stent-graft device with mechanical properties that are comparable with the aorta and aortic arch could possibly lead to fewer post-operative complications, thus, better outcome for patients with complex aneurysm conditions. This review highlights the influence stent-graft design has on the biomechanical properties of the aorta which in turn can contribute to complications of complex aneurysm repair. Design attributes critical for minimising postoperative biomechanical mismatch are also discussed.

description: Hand gesture recognition is a crucial aspect of human-machine interface (HMI) and assistive technology (AT) applications, allowing users to control devices and interfaces through intuitive and natural movements. This study proposed and compares two powerful machine learning (ML) methods, K-Nearest Neighbors (KNN) and fitcensemble (Ensemble of Learners for classification), for real-time hand gesture recognition (HGR) to control a powered wheelchair (PW). Using surface electromyography (sEMG) signals for HGR, this study first explores the KNN algorithm’s potential and demonstrates its exceptional offline accuracy of 99.74%. KNN leverages the similarity of nearby data points to classify hand gestures. Additionally, this study investigates the fitcensemble algorithm as an alternative approach for HGR. This ensemble learning method combines multiple decision trees for improving classification accuracy through diversity and ensemble aggregation. The result shows an impressive 97.68% offline accuracy for fitcensemble, making it promising for the real-time applications. In the real-time implementation and intuitive interface to control the PW by using HGR. This study demonstrates the seamless interaction between the HGR models and the wheelchair control, allowing users to maneuver the wheelchair in a user-friendly manner. Overall, this study contributes to the advancement of AT and HMI by showcasing the efficacy of KNN and fitcensemble for real-time HGR. The achieved accuracy and performance highlight the potential of these methods in real-world applications, promoting enhanced mobility and independence for individuals with limited physical abilities. The findings presented in this study provide valuable insights for researchers, developers, and practitioners working on gesture-based control systems and AT interfaces.

To simulate measurements on rough surfaces the boundary element method (BEM) simulation tool SpeckleSim, developed by the ITO of the University of Stuttgart, is combined with a Fourier optics based image formation. SpeckleSim, which calculates the light-structure interaction by solving the Maxwell equations, is compared with the well-known FEM based solver JCMsuite and the FDTD based solver Ansys Lumerical. As an example, a rectangular shaped line is used as an object. Due to different boundary conditions the results show as expected small deviations, which require further investigations. First comparison results and the general concept of the image formation method will be presented.

description: Presentation at Medical Library Association meeting, April 29, 2022. Objectives: Open science practices have received considerable attention during the COVID-19 pandemic. However, the openness of COVID-19-related randomized controlled trials (RCTs) has yet to be comprehensively assessed. RCTs are frequently referred to as the “gold standard” of evidence which underscores the importance of ensuring their results are rigorous and transparent.

 In this observational study, we are examining the openness of COVID-19 trials along several dimensions, including open access to publications, data sharing, preregistration, and the availability of other research materials (e.g. protocols).

 Methods: After identifying published reports describing the results of COVID-19-related RCTs through a comprehensive literature search, we have begun to extract information- both from the reports themselves and from additional information sources (e.g. Unpaywall)- to characterize their degree of openness.

 In this presentation, we will discuss our preliminary findings as well as how we used this effort to gain experience implementing open science practices ourselves.

description: Thesis defended Desember 2007. The work presented in this thesis deals with instrumental-and method development of various multidimensional on-line liquid chromatography-solid phase extraction-spectroscopy combinations and applications performed utilizing such instrumentation. Reasons for employing on-line instrumentations are, amongst others, the possibility of automation with a lowered risk of human error and greater lab throughput, and the increased ability to handle small sample sizes and low analyte concentrations. Liquid Chromatography (LC)-based on-line systems (i.e. on-line LC-NMR or on-line two dimensional (2D LC)) are available without Solid Phase Extraction (SPE) columns incorporated in the system. However, employing SPE columns have many benefits, such as enabling large volume injections on capillary LC (cap LC) columns, aiding the separation of very large amounts of compounds with conventional HPLC columns and eliminating inter-dimension solvent incompatibility in 2D LC systems. In this thesis it is argued that on-line LC-SPE combinations are well suited tools for solving several key problematic situations encountered in chromatography; when the target compound(s) is often present at very low concentrations in a small sample, and is hence not easy to detect, when the compound(s) of interest must often be separated from the other compounds present, and when the identity of target compound(s) in a mixture is unknown.

title: Constraining Viscous Protoplanetary Disk Models Using ALMA Kinematic Observations
Creators: name: Rabago, Ian
Publisher: name: University of Nevada, Las Vegas
Year: 2020

description: Recent molecular line observations by ALMA have revealed the 3D velocity structure of protoplanetary disks, providing new insight on the mechanisms of disk accretion and ring/gap formation. Although the constant α viscous disk model has been widely used to describe the disk surface density evolution, it may not adequately describe the gas velocity at different disk heights. By carrying out viscous hydrodynamic simulations, we confirm that the vertical velocity structure varies considerably between these models. On the other hand, the surface density evolution of the disk is only dependent on the vertically integrated stress, and does not depend on a particular vertical stress profile. We also include a planet in the 3D simulation to study the kinematic signatures of a young protoplanet. The planet-induced gap causes gas at the gap edge to deviate from Keplerian velocity. This deviation is constant in the vertical direction up to three scale heights in the disk, and the relation between the amplitude of the deviation and the planet mass is consistent with previous relationships derived in 2D simulations. Finally, by removing the planet from the simulation, most of the velocity structure is unchanged and is thus a product of the gap and not the planet. The only notable velocity flows induced by the planet appear in the radial velocity component, away from the planet at the midplane. Overall, axisymmetric observations of the disk can sensitively probe the structure of the rings and gaps, but they cannot exclude other mechanisms besides planets as a process for ring/gap formation.

To explore this concept, I examine Sandra Cisneros, Caramelo, looking at all the mothers, but specifically into the Reyes matriarchs, and Aaron Bobrow-Strain, The Life and Death of Aida Hernandez, to show how the border has influenced Mexican mothering styles, along with juxtaposing how Mexican immigrants were treated in the 20th century to how politicization of the border has led increased policing into the 21st century. Under this timeline, I examine how the border contributes to intergenerational trauma, looking into the effects mixed-status (undocumented vs. documented) families have on children who identify as American but cannot share in this identity with their undocumented mother. This thesis explores how gender roles, tradition, and religion impact the way Mexican woman mother and examine how the border has busted through, leading to pain in both the mother and daughter. This thesis is broken up into three chapters, with chapter one examining how both Mexican mothers and Mexican-American daughters can benefit from Healing Justice and explore how Caramelo and Aida Hernandez hint to those movements of healing, followed with chapter two analyzing the mother figures during the 20th century in Cisneros Caramelo and chapter three exploring how the border disrupts mothering in the 21st century in Bobrow-Strain’s The Life and Death of Aida Hernandez.

description: Pounded yam is a staple starchy food enjoyed by many West African countries. Traditionally, the yam is mashed using a pestle in a mortar, a process that requires significant physical effort and is typically performed by housewives who often lack the necessary strength for this laborious task. Additionally, this traditional method generates excessive sweat and noise, making it unsanitary. This study aims to design and fabricate a yam pounding machine that hygienically processes pounded yam, eliminates the strenuous manual labour, and reduces processing time. During the machine's design and construction, several factors were considered, including the electric motor's power, machine capacity, effectiveness, material availability, and maintenance. The machine was constructed using stainless steel, mild steel, pulleys, belts, bearings, and shafts. Specifically, a type A37 V-belt was used, the bowl's depth is 160 mm, and the beater's dimensions are 73 x 30 x 3 mm. Testing with two different types of yams demonstrated that the yam pounding machine produced hygienic and well-processed pounded yam in less time. The machine completely eliminated the laborious manual pounding process, achieving an efficiency of 88.171%, which is commendable for a locally fabricated machine.
Perspex Machine XIII: Construction of the Transcomplex Numbers from the Complex Numbers

description: New title: Construction of the Transcomplex Numbers From the Complex Numbers. Transcomplex arithmetic is total. In particular this allows division by zero. Hence transcomplex arithmetic permits computations at mathematical singularities, thereby supporting novel computer applications and the design of novel computing machines. A geometrical construction of the transcomplex numbers was given elsewhere. Here we simplify the transcomplex plane and construct the set of transcomplex numbers from the set of complex numbers. Thus transcomplex numbers and their arithmetic arise as consequences of their construction, not by an axiomatic development. This simplies transcomplex arithmetic, compared to the previous treatment, but retains totality so that every arithmetical operation can be applied to any transcomplex number(s) such that the result is a transcomplex number.
title: Thinking About Thinking: Children’s Awareness and Development of Metacognitive Emotion Regulation

description: Metacognitive emotion regulation is a complex system of our underlying thinking that contributes to the emotions that we endure. By gaining an understanding of this concept, young children can learn various strategies, e.g. cognitive reappraisal, problem solving, and delayed gratification, to help alter their thoughts and/or goals to alleviate negative emotion. Thus, they are able to increase their confidence in their own metacognitive emotion regulation abilities and awareness. This study explored the awareness of young children and their metacognitive emotion regulation abilities, the strategies that young children take part in to try and control negative emotion, and the learning strategies that young children pair with developing emotion. This study concluded with knowledge that children rely on cognitive reappraisal in order to promote positive emotion and in turn, control negative emotions.

description: El trabajo contempla una metodología monográfica descriptiva sobre el origen, desarrollo y evolución de la noción de la antijuricidad en la labor de la responsabilidad patrimonial extracontractual, en especial la del Estado, aunque hace referencia a conceptos y teorías propias del derecho privado sobre la materia, por cuanto se encuentran estrechamente relacionadas. Luego de un breve relato, se concentra en la forma como se ha analizado la responsabilidad patrimonial del Estado en el derecho colombiano, antes y después de la introducción del artículo 90 de la Constitución de 1991. En ese orden de ideas, procede a realizar un estudio sobre la utilidad de la noción de daño antijurídico y de las correspondientes críticas sobre los cambios que dicha consagración normativa significó, para encontrar o ratificar finalmente que no implicó ninguna diferencia en relación con la forma como la jurisprudencia contenciosa administrativa resolvía los asuntos antes de su incorporación.
description: The work consists of a descriptive monographic methodology on the origin, development, and evolution of the notion of unlawfulness in the attribution of non-contractual patrimonial responsibility, especially that of the State, although it refers to concepts and theories specific to private law on the subject, as they are closely related. After a brief historical account, it focuses on how the patrimonial responsibility of the State has been analyzed in Colombian law, befare and after the introduction of Article 90 of the Political Constitution of 1991. In that line of thought, it proceeds to conduct a study on the utility of the notion of unlawful damage and the corresponding criticisms of the changes that such normative consecration meant, to finally find or reaffirm that it did not imply any difference in relation to how administrative case law resolved matters befare its incorporation.

description: This thesis investigates antigenic variation and its evolution in Plasmodium falciparum, the cause of the most deadly form of human malaria. Antigenic variation is a strategy for evading immunity by switching between antigenic variants during infection. In P. falciparum, such variable antigens confer different binding phenotypes that may affect parasite survival and have also been linked to pathology. Here, a new statistical method is described for determining the switching patterns that underlie antigenic variation. This method is then applied to experimental data to yield a full description of an antigenic switching network in P. falciparum. In light of the findings, theoretical modelling is used to show how immune selection and binding phenotypes may have contributed to the evolution of antigenic repertoire structure, expression order and virulence. Related models are also used to investigate parasite population diversity, providing possible explanations for observations reported here and elsewhere, with implications for vaccine design. Together, these chapters advance understanding of P. falciparum immune evasion and how it relates to pathology. This work further reinforces the role of host immunity in shaping pathogen population diversity at multiple levels.

description: Objectives: To explore the impact of uninterrupted sitting versus sitting with resistance-type activity breaks on adolescents' postprandial glucose responses while consuming a diet varying in energy. Design: Cross-over randomised trial. Methods: Thirteen healthy participants (16.4. ±. 1.3. years) completed a four-treatment cross-over trial: (1) uninterrupted sitting + high-energy diet; (2) sitting with breaks + high-energy diet; (3) uninterrupted sitting + standard-energy diet; and (4) sitting with breaks + standard-energy diet. For all four conditions, two identical meals were consumed; at 0. h and 3. h. A continuous glucose monitoring system (CGM) recorded interstitial glucose concentrations every five minutes. Linear mixed models examined differences in glucose positive incremental area under the curve (iAUC) and total AUC between the sitting and diet conditions for the first meal, second meal and entire trial period. Results: Compared to the uninterrupted sitting conditions, the breaks condition elicited a 36.0. mmol/L/h (95%CI 6.6-65.5) and 35.9. mmol/L/h (95%CI 6.6-65.5) lower iAUC response after the first and second meal, respectively, but not for the entire trial period or for total AUC. Compared to the standard-energy diet, the high-energy diet elicited a 55.0. mmol/L/h (95%CI 25.8-84.2) and 75.7. mmol/L/h (95%CI 8.6-142.7) higher iAUC response after the first meal and entire trial, respectively. Similar response to the high-energy diet were observed for total AUC. Conclusions: According to iAUC, interrupting sitting had a significant effect on lowering postprandial glucose for both dietary conditions, however, it was not significant when examining total AUC. Larger studies are needed to confirm these findings. Clinical Trial Registration Number: ACTRN12615001145594.
