Research on Model Updating Method of Derrick Structures Based on Sensitivity Analysis

The model updating method of the derrick structure based on the modal sensitivity analysis is discussed.In this method,the design parameters of the derrick structure such as materials,cross-section shapes and geometric size are directly updated,the objective function and state variables of optimal model are determined,and the first-order optimization algorithm is used to optimize parameters and assess state.The method has been verified by experimental analysis of simple derrick model.This method provides a new idea for complex structural damage identification and safety monitoring.It is suitable for practical engineering applications,because the first-order method of ANSYS optimization is used to update the FE model and the sensitivity analysis and model updating are completely based on ANSYS software.

Objective To study the sanitary condition of source water in Xinhui district of Jiangmen city.Methods The monitoring data of source water were collected and analyzed from 2008 to 2012.Results The pass rates of iron,total nitrogen,manganese and fecal coliform were low; There was significant difference from year to year in pass rates(χ2= 11.74,P 0.05); There was no significant difference among wet period,dry period and level period in pass rates(P 0.05);The pass rate of water quality of reservoir was higher than that of rivers(χ2= 23.01,P 0.05).Conclusion The indexes of iron,total nitrogen,manganese and fecal coliform are the main pollutants in source water of Xinhui district of Jiangmen city,and it is necessary to take steps in protecting source water and harnessing the pollution of source water.
Personalized Expert Skeleton Scaffolding in Concept Map Construction

Concept maps have been widely used in educational contexts to facilitate meaningful learning. Recent research has examined how concept mapping tools assist students in summarizing, relating, and organizing concepts. Our goal is to explore how personalized scaffolding can be applied to concept map construction. We provide personalized scaffolding in the form of an adaptive expert skeleton map based on student prior knowledge. We conducted a study comparing the adaptive map to a fixed map and to unscaffolded concept mapping. In an exploratory analysis, we examine the possible impacts of adaptive scaffolding on student learning processes.
Fostering an Active Learning Environment for Undergraduates: Peer-to-Peer Interactions in a Research Group.

The benefits of active learning in the traditional classroom setting are well established among engineering educators; however, this learning model can thrive in other settings, namely in a research group. This work presents findings from an educational research project specifically designed to foster active learning among undergraduates and graduate students. Observations and data were collected in the Research Communications Studio (RCS), which uses the research group as a forum for active learning. Distributed cognition is a key concept behind the structure of the RCS. Specific practices that facilitate active participation are described, and a quantitative analysis of group discourse is used to confirm activity levels and to characterize the nature of the group interactions. The methods used to foster active learning can be adapted to a variety of research group settings.
Catalytic strategy for carbon−carbon bond scission by the cytochrome P450 OleT

OleT is a cytochrome P450 that catalyzes the hydrogen peroxide-dependent metabolism of C n chain-length fatty acids to synthesize C n-1 1-alkenes. The decarboxylation reaction provides a route for the production of drop-in hydrocarbon fuels from a renewable and abundant natural resource. This transformation is highly unusual for a P450, which typically uses an Fe 4+ −oxo intermediate known as compound I for the insertion of oxygen into organic substrates. OleT, previously shown to form compound I, catalyzes a different reaction. A large substrate kinetic isotope effect (≥8) for OleT compound I decay confirms that, like monooxygenation, alkene formation is initiated by substrate C−H bond abstraction. Rather than finalizing the reaction through rapid oxygen rebound, alkene synthesis proceeds through the formation of a reaction cycle intermediate with kinetics, optical properties, and reactivity indicative of an Fe 4+ −OH species, compound II. The direct observation of this intermediate, normally fleeting in hydroxylases, provides a rationale for the carbon−carbon scission reaction catalyzed by OleT.
Paradoxical Trend for Improvement in Mental Health With Aging: A Community-Based Study of 1,546 Adults Aged 21-100 Years.

Objective Studies of aging usually focus on trajectories of physical and cognitive function, with far less emphasis on overall mental health, despite its impact on general health and mortality. This study examined linear and nonlinear trends of physical, cognitive, and mental health over the entire adult lifespan. Methods Cross-sectional data were obtained from 1,546 individuals aged 21-100 years, selected using random digit dialing for the Successful AGing Evaluation (SAGE) study, a structured multicohort investigation that included telephone interviews and in-home surveys of community-based adults without dementia. Data were collected from 1/26/2010 to 10/07/2011 targeting participants aged 50-100 years and from 6/25/2012 to 7/15/2013 targeting participants aged 21-100 years with an emphasis on adding younger individuals. Data included self-report measures of physical health, measures of both positive and negative attributes of mental health, and a phone interview-based measure of cognition. Results Comparison of age cohorts using polynomial regression suggested a possible accelerated deterioration in physical and cognitive functioning, averaging 1.5 to 2 standard deviations over the adult lifespan. In contrast, there appeared to be a linear improvement of about 1 standard deviation in various attributes of mental health over the same life period. Conclusions These cross-sectional findings suggest the possibility of a linear improvement in mental health beginning in young adulthood rather than a U-shaped curve reported in some prior studies. Lifespan research combining psychosocial and biological markers may improve our understanding of resilience to mental disability in older age and lead to broad-based interventions promoting mental health in all age groups.
Why do we behave the way we do

Changing high risk behaviours involves progress through six stages of change: precontemplation, contemplation, preparation, action, maintenance and termination. Stage-matched programs for cardiovascular disease prevention can produce much higher participation rates than traditional action-oriented programs (80 to 85% versus 1 to 5%). The amount of success following intervention is directly related to the state of change participants are in before intervention. Helping people progress through the stages involves matching particular processes and principles of change to particular stages of change.
Race, Age, and Neighborhood Socioeconomic Status in Low Birth Weight Disparities Among Adolescent Mothers: An Intersectional Inquiry.

INTRODUCTION Few studies examined socioeconomic contributors to racial disparities in low birth weight outcomes between African-American and Caucasian adolescent mothers. This cross-sectional study examined the intersections of maternal racial status, age, and neighborhood socioeconomic status in explaining these disparities in low birth weight outcomes across a statewide sample of adolescent mothers. METHODS Using data from the North Carolina State Center of Health Statistics for 2010-2011, birth cases for 16,472 adolescents were geocoded by street address and linked to census-tract information from the 2010 United States Census. Multilevel models with interaction terms were used to identify significant associations between maternal racial status, age, and neighborhood socioeconomic status (as defined by census-tract median household income) and low birth weight outcomes across census tracts. RESULTS Significant racial differences were identified in which African-American adolescents had greater odds of low birth weight outcomes than Caucasian adolescents (OR=1.88, 95% CI 1.64, 2.15). Although racial disparities in low birth weight outcomes remained significant in context of maternal age and neighborhood socioeconomic status, the greatest disparities were found between African-American and Caucasian adolescents that lived in areas of higher socioeconomic status (p<.001). Maternal age was not significantly associated with racial differences in low birth weight outcomes. CONCLUSION These findings indicate that racial disparities in low birth weight outcomes among adolescent mothers can vary by neighborhood socioeconomic status. Further investigations using intersectional frameworks are needed for examining the relationships between neighborhood socioeconomic status and birth outcome disparities among infants born to adolescent mothers.
Commonsense Problems with Substance

In this chapter, I analyze the neo-Aristotelian account of substances, as requiring substances to be ontologically fundamental, independent, and non-relational. I argue that these requirements are interdependent and that a problem for any one of these requirements poses challenges to the others. By looking at the problem of substantial change, and how it poses challenges for the requirement of ontological fundamentality, the neo-Aristotelian’s requirement of ontological independence becomes difficult to fulfill. The result being that the neo-Aristotelian account of substance requires refinement if we are to accept it as a metaphysical theory.
Summary of the Conference on the Meteorological and Oceanographic Uses of Satellites in Molniya Orbits

Only two orbits are in common use for meteorological satellites. Geostationary satellites (GEOs) orbit at about 35 790 km above the equator with the same angular velocity as the earth, so that the satellite remains stationary above a selected meridian. This orbit has the considerable advantage that images can be made frequently, which allows the time evolution of rapidly developing weather phenomena to be observed and studied. Low earth orbiters (LEOs), such as the sunsynchronous NOAA satellites, orbit between about 600 and 1500 km above the surface. They have the advantage that a single instrument can observe the entire earth, but only the poles are observed frequently (once each orbit). Most of the rest of the earth is viewed twice per day. Neither of these orbits serve the high latitudes well. The geostationary satellites cannot view the poles at all, and the high latitudes are observed poorly due to the slant angle. LEOs observe the high latitudes only two to four times per day, separated by long gaps...
Immunotherapy Response Assessment in Neuro-Oncology (iRANO)

Abstract We have formed an international working group of brain tumor immunotherapy experts to develop novel Immunotherapy Response Assessment in Neuro-Oncology (iRANO) criteria (Okada et al., 2015). The generation of these criteria was motivated by the challenges of assessing radiological changes reflecting delayed responses or therapy-induced inflammation in immunotherapy clinical trials. Clinical benefits, such as long-term survival and tumor regression, can still occur following initial progression or appearance of new lesions. According to the iRANO criteria, it is recommended that patients who demonstrate imaging findings meeting traditional criteria for progressive disease (PD) ascertain confirmation of radiographic progression on follow-up imaging, provided that the patient's clinical condition has not significantly declined. Our proposed criteria also include guidelines for use of corticosteroids. As application of immunotherapies for neuro-oncology patients is in early stages, prospective evaluation of the iRANO criteria will be required to confirm their ultimate clinical utility, and the guidelines will inevitably require careful updates and amendments based upon data derived from ongoing and future studies.
Family Socialization for Racism and Heterosexism: Experiences of Latinx Sexual Minority Adolescents and Young Adults

Fluorescence Probes of Protein Dynamics and Conformations in Freely Diffusing Molecules

The results described here demonstrate that single-molecule fluorescence spectroscopy of molecules freely diffusing in solution can yield unique information about both the dynamics and conformations of proteins. We used single-molecule FRET to detect the dynamics in CaM on the timescales of 100’s of microseconds and a few milliseconds by cross-correlation analysis of the donor and acceptor signals. In addition, analysis of the distribution of donor-acceptor distances by single-molecule FRET demonstrates the presence of three distinct conformational substates of CaM in solution. Together these results paint a picture of a protein that is dynamic and flexible, accessing a range of distinct conformation substates in solution.
Specimen Preparation Methods for Microstructural Analysis

Technological advances of the last few decades would seem to have greatly compounded the work of those preparing materials for analysis. This is due not only to the production of new materials but also to the development of new types of instrumentation. The scope of specimen preparation techniques required today may be further inferred from the definition of metallography given by Cochran (1). He states, “Metallography is the study of the internal or surface structure of materials whether by optical, electron, x-ray, microprobe, field-ion or emission analysis.” For the purpose of this paper, this definition will be extended to cover the broader field of microstructural analysis.
Common Consumer Health-Related Needs in the Pediatric Hospital Setting: Lessons from an Engagement Consultation Service.

Background Informed and engaged parents may influence outcomes for childhood illness. Understanding the needs of the caregivers of pediatric patients is a critical first step in promoting engagement in their child's care. In 2014, we developed an Engagement Consultation Service at the Monroe Carell Jr. Children's Hospital at Vanderbilt. This service determines the health-related needs of the caregivers of hospitalized children and makes educational or technology recommendations to meet those needs and support engagement. Objectives This report describes the most common health-related needs identified in the caregivers of hospitalized pediatric patients and details the recommended interventions to meet those needs. Methods The most commonly reported consumer health-related needs from our 3-year experience with the Engagement Consultation Service were extracted from consultations notes. Each need was classified by semantic type using a taxonomy of consumer health needs. Typical recommendations for each need and their administration were detailed. Results The most frequently recognized needs involved communicating with health care providers after discharge, using medical devices, distinguishing between benign and concerning symptoms, knowing what questions to ask providers and remembering them, finding trustworthy sources of information online, understanding disease prognosis, and getting emotional support. A variety of apps, Web sites, printed materials, and online groups were recommended. Conclusion The parents of hospitalized patients share several common health-related needs that can be addressed with educational and technology interventions. An inpatient Engagement Consultation Service provides a generalizable framework for identifying health-related needs and delivers tools to meet those needs and promote engagement during and after hospitalizations.
Management of Posttraumatic Ankle Arthritis: Literature Review

Trauma is the principle cause of osteoarthritis in the ankle, which is associated with significant morbidity. This review highlights the current literature for the purpose of bringing the reader up-to-date on the management of posttraumatic ankle arthritis, describing treatment efficacy, indications, contraindications, and complications. Recent studies on osteoarthritis have demonstrated variability among anatomic locations regarding the mechanisms and rates of development for posttraumatic osteoarthritis, which are attributed to newly discovered biological differences intrinsic to each joint. Regarding surgical management of posttraumatic ankle arthritis, osteochondral allograft transplantation of the talus, and supramalleolar osteotomies have demonstrated promising results. Additionally, the outpatient setting was found to be appropriate for managing pain following total ankle arthroplasty, associated with low complication rates and no readmission. Management for posttraumatic ankle arthritis is generally progressive. Initial treatment entails nonpharmacologic options with surgery reserved for posttraumatic ankle arthritis refractory to conservative treatment. Patient demographics and lifestyles should be carefully considered when formulating a management strategy, as outcomes are dependent upon the satisfaction of each set of respective criteria. Ultimately, the management of posttraumatic ankle arthritis should be individualized to satisfy the needs and desires, which are specific to each patient.
Exploring Challenges in Conducting E-Mental Health Research Among Asian American Women

In this discussion paper, we explore the challenges of conducting e-mental health intervention research among Asian American women and propose a model for addressing these barriers. Based on an extensive literature review, we identify two main types of barriers to conducting e-mental health intervention research among Asian American women: recruitment barriers and adherence barriers. Recruitment barriers are further subcategorized into those related to (1) stigmatized cultural beliefs about mental illness and mental health services; (2) lack of awareness about mental health services; and (3) language barrier. As to adherence barriers, the two identified subtypes concern (1) acuity and severity of mental health condition; and (2) lack of time. In order to enhance recruitment and adherence in e-mental health intervention research among the studied population, we formulate the following three main research strategies, namely: (1) considering the cultural and social contexts of Asian American women in the development of e-mental health interventions; (2) determining appropriate program length; and (3) conducting feasibility studies to test e-mental health interventions. We suggest that nurse researchers integrate our proposed model in conducting e-mental health interventions among Asian American women. Our proposed model also implies that nurses play an important role in encouraging Asian American women’s acceptance of and adherence to e-mental health interventions. In order to overcome the obstacles to conducting e-mental health research among Asian American women, we recommend that nurses familiarize themselves with credible, relevant, and evidence-based e-mental health resources and integrate online mental health services and information within their nursing practice.
Toward a Poetics of the Other: New Directions in Post-scientific Psychology

During the course of the past two decades, calls have been made for establishing what is herein called a “poetics of the Other” (e.g., Freeman, Theory beyond theory. Theory & Psychology, 10, 71–77, 2000; The priority of the other: Thinking and living beyond the self. New York: Oxford University Press, 2014). In this perspective, the idea of the Other comes to assume a measure of priority over the self in understanding human experience. Moreover, poetics comes to assume priority over theoretics, at least as the latter is traditionally understood. This project need not lead beyond the purview of theoretical psychology. But it does point in the direction of a quite different sense of what theoretical psychology—and theory itself—might mean. In efforts to keep within the basic framework of contemporary academic psychology, this project has generally been framed as a potential contributor to the re-imagining of psychological science (e.g., Freeman, Toward poetic science. Integrative Psychological and Behavioral Science, 45, 389–396, 2011; Narrative psychology as science and as art. In J. Valsiner, G. Marsico, N. Chaudhary, T. Sato, & V. Dazzani (Eds.), Psychology as a science of human being: The Yokohama Manifesto (pp. 349–364). Switzerland: Springer, 2015). This stands to reason; to frame what one does as something other than science, one runs the risk not only of alienating one’s colleagues (whether for one’s putative hostility to science or one’s inability to move beyond binary thinking, here manifested in the form of the science/non-science divide) but also of effectively banishing oneself from the discipline proper. It is this idea of the discipline proper, however, that most warrants interrogation. It may be time now to carve a suitable space for thinking more radically about what psychology is and must be. For present purposes, this space may be deemed “post-scientific”—which is to say, it seeks to explore that region of experience which remains after science has done its work. The good news is, it is a large one indeed and well worth the attention of those seeking to “think Otherwise” (Freeman, Thinking and being otherwise: Aesthetics, ethics, erotics. Journal of Theoretical and Philosophical Psychology, 32, 196–208, 2012) about both psychology and the human condition.

The extracellular matrix of the blood–brain barrier: structural and functional roles in health, aging, and Alzheimer’s disease

There is increasing interest in defining the location, content, and role of extracellular matrix (ECM) components in brain structure and function during development, aging, injury, and neurodegeneration. Studies in vivo confirm brain ECM has a dynamic composition with constitutive and induced alterations that impact subsequent cell-cell and cell-matrix interactions. Moreover, it is clear that for any given ECM component, the brain region, and cell type within that location, determines the direction, magnitude, and composition of those changes. This review will examine the ECM at the neurovascular unit (NVU) and the blood-brain barrier (BBB) within the NVU. The discussion will begin at the glycocalyx ECM on the luminal surface of the vasculature, and progress to the abluminal side with a focus on changes in basement membrane ECM during aging and neurodegeneration.

The Second Founding: An Introduction to the Fourteenth Amendment

In The Second Founding: An Introduction to the Fourteenth Amendment, Ilan Wurman provides an illuminating introduction to the original meaning of the Fourteenth Amendment's famous provisions 'due process of law,' 'equal protection of the laws,' and the 'privileges' or 'immunities' of citizenship. He begins by exploring the antebellum legal meanings of these concepts, starting from Magna Carta, the Statutes of Edward III, and the Petition of Right to William Blackstone and antebellum state court cases. The book then traces how these concepts solved historical problems confronting framers of the Fourteenth Amendment, including the comity rights of free blacks, private violence and the denial of the protection of the laws, and the notorious abridgment of freedmen's rights in the Black Codes. Wurman makes a compelling case that, if the modern originalist Supreme Court interpreted the Amendment in 'the language of the law,' it would lead to surprising and desirable results today.
Deletion of newly described pro-survival molecule Pellino-1 increases oxidative stress, downregulates cIAP2/NF-κB cell survival pathway, reduces angiogenic response, and thereby aggravates tissue function in mouse ischemic models.

In the present study, we aimed to explore the functional role of Pellino-1 (Peli1) in inducing neovascularization after myocardial infarction (MI) and hindlimb ischemia (HLI) using Peli1 global knockout mice (Peli1−/−). Recently we have shown that Peli1, an E3 ubiquitin ligase, induce angiogenesis and improve survivability, with decreased necrosis of ischemic skin flaps. Peli1fl/fl and Peli1−/− mice were subjected to either permanent ligation of the left anterior descending coronary artery (LAD) or sham surgery (S). Tissues from the left ventricular risk area were collected at different time points post-MI. In addition, Peli1fl/fl and Peli1−/− mice were also subjected to permanent ligation of the right femoral artery followed by motor function scores, Doppler analysis for blood perfusion and immunohistochemical analysis. Global Peli1 knockout exacerbated myocardial dysfunction, 30 and 60 days after MI compared to wild type (WT) mice as measured by echocardiogram. In addition, Peli1−/− mice also showed decreased motor function scores and perfusion ratios compared with Peli1fl/fl mice 28 days after the induction of HLI. The use of Peli1 in adenoviral gene therapy following HLI in CD1 mice improved the perfusion ratio at 28 days compared to Ad.LacZ-injected mice. These results suggest new insights into the protective role of Peli1 on ischemic tissues and its influence on survival signaling.
Abstract 226: Pathways of nucleotide synthesis in NSCLC

Tracer-based mapping of metabolic networks is a powerful approach for revealing metabolic reprogramming in human cancer. Nucleotide synthesis and turnover is critical for cell proliferation and is tightly regulated [1,2]. We have developed NMR and tandem MS methods for determining the active pathways of the synthesis of free nucleotides and nucleotide sugars including UDP-Glucose and UDPGlcNAc using multiplexed stable isotope resolved metabolomics (mSIRM)[3] in a variety of models including freshly resected lung tumor tissue, mouse PDX and organoids. Using multiple isotopic labels (13C, 2H and 15N) we determined the relative contributions to purine and pyrimidine nucleotide synthesis of both exogenous glucose, glutamine, serine and glycine and metabolically-derived intracellular precursors. We have used these approaches to compare the relative importance of different metabolic pathways in NSCLC under various conditions to assess the role of the tumor microenvironment, and how these pathways are impacted by arsenite and selenite. Our findings indicate that the substrates for de novo nucleotide synthesis may differ profoundly between cancer cell lines and fresh human lung cancer tissues; for purines, the latter preferred glucose to exogenous serine or glycine but not the former. Pyrimidine nucleotides also utilize glucose for ribose synthesis via the pentose phosphate pathway, but both glucose and glutamine for the pyrimidine rings depending on the conditions and cell type. This distinction in substrate utilization in nucleotide synthesis in human cancer tissues should be considered when targeting one-carbon metabolism for cancer therapy.

Quantum criticality in Ce 1 −x Sm x Co In 5

Motivated by the possibility of observing the coexistence between magnetism and unconventional superconductivity in heavy-fermion ${\mathrm{Ce}}_{1\ensuremath{-}x}{\mathrm{Sm}}_{x}\mathrm{Co}{\mathrm{In}}_{5}$ alloys, we studied how the samarium substitution on the cerium site affects the magnetic field-tuned-quantum criticality of stoichiometric $\mathrm{Ce}\mathrm{Co}{\mathrm{In}}_{5}$ by performing specific heat and resistivity measurements. By applying an external magnetic field, we have observed Fermi-liquid to non-Fermi-liquid crossovers in the temperature dependence of the electronic specific heat normalized by temperature and of the resistivity. We obtained the magnetic-field-induced quantum critical point (QCP) by extrapolating to zero temperature the temperature-magnetic field dependence at which the crossovers take place. Furthermore, a scaling analysis of the electronic specific heat is used to confirm the existence of the QCP. We have found that the magnitude of the magnetic-field-induced QCP decreases with increasing samarium concentration. Our analysis of heat capacity and resistivity data reveals a zero-field QCP for ${x}_{\text{cr}}\ensuremath{\approx}0.15$, which falls inside the region where Sm ions antiferromagnetism and superconductivity coexist.
Assessment of diverse image encryption mechanisms under prevalent invasion

Image encryption mechanisms provide confidentiality and concealment of information (image) in transmission over the alleyway, susceptible to prevalent invasions. With escalating threats in cybersecurity, various cryptography techniques were projected by researchers. The abundance of such mechanisms requires systematic investigation so that that appropriate method can be selected for diverse applications. An efficient encryption technique must analyze all the parameters in an ideal situation and practical cases. Numerous survey papers available in the literature for experimental comparison are devoid of many probable attacks such as anti occlusion attack, chosen-plaintext attack, jpeg compression, etc. This paper provides a qualified study of almost all basic, traditional, chaotic, lightweight, quantum, fractal, and qubit based encryption methods under the influence of prevalent intimidation (Salt & Pepper, Gaussian, Poisson, Rotation attack, chosen-plaintext attack, known-plaintext attack, and so on). We thus carried out an experimental and theoretical investigation based on statistical, differential, and quantitative analysis. To measure the efficacy, all the mechanisms are implemented in MATLAB-2014 and provide the standard deviation to each metric. It is observed that the Quantum and Qubit based algorithms are superlative in comparison to others under the majority of extensive threats due to their sensitive behaviour towards initial conditions and highly random behaviour.
Judging a type by its pointer: optimizing GPU virtual functions

Programmable accelerators aim to provide the flexibility of traditional CPUs with significantly improved performance. A well-known impediment to the widespread adoption of programmable accelerators, like GPUs, is the software engineering overhead involved in porting the code. Existing support for C++ on GPUs allows programmers to port polymorphic code with little effort. However, the overhead from the virtual functions introduced by polymorphic code has not been well studied or mitigated on GPUs. To alleviate the performance cost of virtual functions, we propose two novel techniques that determine an object’s type based only on the object’s address, without accessing the object’s embedded virtual table pointer. The first technique, Coordinated Object Allocation and function Lookup (COAL), is a software-only solution that allocates objects by type and uses the compiler and runtime to find the object’s vTable without accessing an embedded pointer. COAL improves performance by 80%, 47%, and 6% over contemporary CUDA, prior research, and our newly-proposed type-based allocator, respectively. The second solution, TypePointer, introduces a hardware modification that allows unused bits in the object pointer to encode the object’s type, improving performance by 90%, 56%, and 12% over CUDA, prior work, and our new allocator. TypePointer can also be used with the default CUDA allocator to achieve an 18% performance improvement without modifying object allocation.

Corrosion in Molten Salts for Solar Thermal Power

Global energy needs continue to grow steadily with increasing population and standard of living. While fossil fuels have been a major source of our energy, they are no longer favorable due to their greenhouse gas emissions and atmospheric pollution; the development of carbon-free sources of energy is crucial. Solar energy promises unlimited amounts of emissions-free energy but suffers from intermittency issues that require expensive secondary energy storage systems to act as baseload power. A thermal energy storage (TES) system can store heat and provide a continuous source of power. Concentrated solar power (CSP) is carbon-free and can ideally be combined with a TES system to provide continuous power. These combined systems operate by focusing a large area of sunlight onto a receiver that contains a TES material to convert the sunlight into thermal energy.
Anatomy-oriented Stereotactic Approach to Cerebrospinal Fluid Collection in Mice

Abstract Extraction of cerebrospinal fluid (CSF) in small animal models is an indispensable technique used in neuroscience and neuro-oncology research but can be technically challenging due to the small size of the brain. Here we describe a simple, reliable, and highly reproducible method for collecting CSF from anesthetized laboratory mice based on anatomical foundation, with no requirement of introducing any custom-made types of equipment. The mouse’s head is fixed to a stereotaxic frame in the position that allows the maximum opening of the cisterna magna. A Hamilton syringe attached with a 26 gauge needle is inserted stereotactically in parallel to the brain axis to reach the cistern. The clear CSF (approximately 10 microliters) can then be drawn slowly in approximately 5 minutes. Our modified approach minimizes technical variations that can result from customized equipment and is applicable in broad research settings.
VTSV: A Privacy-Preserving Vehicle Trajectory Simulation and Visualization Platform Using Deep Reinforcement Learning

Trajectory data is among the most sensitive data and the society increasingly raises privacy concerns. In this demo paper, we present a privacy-preserving Vehicle Trajectory Simulation and Visualization (VTSV) web platform (demo video: https://youtu.be/NY5L4bu2kTU), which automatically generates navigation routes between given pairs of origins and destinations and employs a deep reinforcement learning model to simulate vehicle trajectories with customized driving behaviors such as normal driving, overspeed, aggressive acceleration, and aggressive turning. The simulated vehicle trajectory data contain high-sample-rate of attributes including GPS location, speed, acceleration, and steering angle, and such data are visualized in VTSV using streetscape.gl, an autonomous driving data visualization framework. Location privacy protection methods such as origin-destination geomasking and trajectory k-anonymity are integrated into the platform to support privacy-preserving trajectory data generation and publication. We design two application scenarios to demonstrate how VTSV performs location privacy protection and customize driving behavior, respectively. The demonstration shows that VTSV is able to mitigate data privacy, sparsity, and imbalance sampling issues, which offers new insights into driving trajectory simulation and GeoAI-powered privacy-preserving data publication.
Gewalt und Staatsversagen in Fidschi

Between 1987 and 2006 Fiji experienced four coups in which governments were overthrown by their own military forces. Many observers attribute political violence in Fiji to ethnic tensions between indigenous ethnic Fijians and descendants of persons of Indian origin, who immigrated to Fiji mainly between 1880 and 1920. While ethnicity contributes to political instability in Fiji, the existence of additional cleavages based on class, kinship and centre-periphery dichotomy creates a rather complex picture. The coups are also offsprings of conflicts within the Fijian society, conflicts about the loss of political and economic power in the course of modernization, experienced by traditional chiefs of tribal confederacies, as well as conflicts caused by marginalization of indigenous people living in peripheral areas. External actors like Australia, New Zealand and the USA add another layer to the conflicts. During the socalled Cold War the Pacific islands were nuclear testing grounds for the USA, France and Great Britain as well as a strategic region for the US-American Pacific fleet. Since 9/11 the USA as well as Australia and New Zealand consider political instability in the Pacific island region as a breeding ground for international terrorism and thus a threat to their national security.
A note on independent variables for restricted three-body problems

In studies of the elliptic restricted three-body problem, the true anomaly of the motion of the primaries is often used as the independent variable. The equations of motion then show invariancy in form from the circular case. It is of interest whether other independent variables exist, such that the invariant form of the equations is maintained. It is found that true anomaly is the only such variable.

Guidelines for managing mathematical software libraries at computer centers

This paper sets down some of the issues involved in supporting mathematical software libraries and describes procedures that have been used with moderate success. As is often the case in human relations, the attitudes and personalities of the people involved have as much influence on the effectiveness of the service as the procedures one defines.
Image Sampling and Reconstruction

The chapter reviews sampling in both two-dimensional spatial and one-dimensional wavelength dimensions. It is assumed the reader has previously reviewed one-dimensional sampling for time domain signals at the level of undergraduate courses. Examples are included that show the effects of undersampling in theory and practice. The reconstruction of images is presented for both reproduction of an original image and the enlargement of images that is required so often in windows-based image analysis. Keywords: sampling; aliasing; two-dimensional; imaging; reconstruction; interpolation; color; wavelength
Microstuctural Characterization of Water-Rich Boehmite (AlO(OH)): TEM Correlation of Apparently Divergent XRD and TGA Results

An understanding of the solid-phase thermodynamics and aqueous speciation of aluminum is critical to our ability to understand and predict processes in a wide variety of geologic and industrial settings. Boehmite (AIO(OH)) is an important phase in the system Al2O3-H2O that has been the subject of a number of structural and thermodynamic studies since its initial synthesis [l] and discovery in nature [2]. Unfortunately, it has long been recognized that thermogravimetric analysis (TGA) of both synthetic and natural boehmite samples (that appear well crystallized by powder XRD methods) yields significant excess water - typically losing 16-16.5 wt. % on heating as compared with a nominal expected weight loss of 15.0 wt. % [3,4]. The boehmite used in our experiments was synthesized hydrothermally from acid-washed gibbsite (Al(OH)3) at 200°C. Powder XRD and SEM examination showed no evidence of the presence a contaminant phase. The TGA patterns do not suggest that this is due to adsorbed water, so a structural source is likely. We therefore undertook to examine this material by TEM to clarify this phenomenon.

Examining mechanisms of brain control of bladder function with resting state functional connectivity MRI.

Aims This aim of this study is to identify the brain mechanisms involved in bladder control. Methods We used fMRI to identify brain regions that are activated during bladder filling. We then used resting state connectivity fMRI (rs-fcMRI) to assess functional connectivity of regions identified by fMRI with the rest of the brain as the bladder is filled to capacity. Results Female participants (n = 20) were between ages 40 and 64 with no significant history of symptomatic urinary incontinence. Main effect of time (MET) fMRI analysis resulted in 20 regions of interest (ROIs) that have significant change in BOLD signal (z = 3.25, P <0.05) over the course of subtle bladder filling and emptying regardless of full versus empty bladder state. Bladder-state by time (BST) fMRI analysis resulted in three ROIs that have significant change in BOLD signal (z = 3.25, P <0.05) over the course of bladder runs comparing full versus empty bladder state. Rs-fcMRI fixed effects analysis identified significant changes in connectivity between full and empty bladder states in seven brain regions (z = 4.0) using the three BST ROIs and sixteen brain regions (z = 7) using the twenty MET ROIs. Regions identified include medial frontal gyrus, posterior cingulate (PCC), inferiolateral temporal and post-central gyrus, amygdale, the caudate, inferior parietal lobe as well as anterior and middle cingulate gyrus. Conclusions There is significant and vast changes in the brain's functional connectivity when bladder is filled suggesting that the central process responsible for the increased control during the full bladder state appears to largely rely on the how distributed brain systems are functionally integrated.

Should we try to squeeze database-backed websites into the curriculum: and, if so, where?

This paper describes a set of labs packaged as a tutorial and designed to teach students how to build database-backed web sites. These labs can be used within a variety of existing courses and need only three weeks to complete. Students need prerequisite knowledge of HTML, Visual Basic or VBScript, and the ability to build a simple database using Microsoft Access. The author describes three courses in which the labs have been successfully used and documents the results. Examples of final projects are included. The appendix contains the code from one lab exercise. Student handouts can be downloaded from the tutorial website, and an instructor's guide and lab solutions are available from the author.
Gender, Political Rhetoric, and Moral Metaphors in State of the City Addresses

Politicians and leaders use metaphors and frames in political communication to provide citizens with meaning, persuade, and promote emotional reactions. At the same time, a large body of scholarship documents the propensity for female leaders to “speak in a different voice” when in political office. Research to date on policy metaphors, however, rarely compares male and female leaders’ use of metaphors or evaluates the use of these metaphors in local politics. Using State of the City addresses from 16 cities to evaluate the connection between policy agendas, metaphors, and mayoral gender, I find that male and female leaders emphasize similar issues in their speeches, but use different frames to present these issues, with female leaders using more nurturing framing than do male leaders. In addition, while both male and female mayors emphasize economic development as the central issue in their speeches, female mayors use more inclusive framing in these discussions.
Underground Muons in Super-KAMIOKANDE

The largest underground neutrino observatory, Super-Kamiokande, located near Kamioka, Japan has been collecting data since April 1996. It is located at a depth of roughly 2.7 kmwe in a zinc mine under a mountain, and has an effective area for detecting entering-stopping and through-going muons of about $1238 m^2$ for muons of $>1.7 GeV$. These events are collected at a rate of 1.5 per day from the lower hemisphere of arrival directions, with 2.5 muons per second in the downgoing direction. We report preliminary results from 229 live days analyzed so far with respect to zenith angle variation of the upcoming muons. These results do not yet have enough statistical weight to discriminate between the favored hypothesis for muon neutrino oscillations and no-oscillations. We report on the search for astrophysical sources of neutrinos and high energy neutrino fluxes from the sun and earth center, as might arise from WIMP annihilations. None are found. We also present a topographical map of the overburden made from the downgoing muons. The detector is performing well, and with several years of data we should be able to make significant progress in this area.
