Differential Very Long Baseline Interferometry (delta VLBI) spacecraft tracking system demonstration. Part 2: Data acquisition and processing

A set of experiments in the use of Differential Very Long Baseline Interferometry (delta VLBI) for spacecraft navigation were completed. Data using both Voyager spacecraft and a single quasar were acquired during the Jupiter encounter time period. The data were processed and analyzed to assess the navigation accuracy of delta VLBI. The data reduction and techniques for assessing data quality and consistency are discussed

You Can Get There from Here: A Phenomenological Study of Help-Seeking Behavior and Experiences of Student Military Veterans in Community College

This phenomenological study described the experiences of student military veterans in a community college with physical and psychological health needs. Each participant enrolled in the community college by utilizing the benefits of the post-9/11 GI Bill and transitioned from active duty to civilian life. More than 40,000 programs in the United States are designed to assist veterans transitioning to civilian life (Carter, 2013). Further, the health needs and transition experiences of military veterans have been well-documented. Numerous programs seek to reduce barriers; however, many veterans experience challenges when using the programs or services (Perkins et al., 2019; Aronson et al., 2019). Previous studies suggested that veterans reported not using services during the reintegration process for the following reasons: many felt they did not need help, had difficulty identifying a program or service that adequately met their needs, did not understand the types of programs they qualified for, and did not know where to acquire assistance (Morgan et al., 2020). Employing purposive sampling and the Moustakas (1994) method for phenomenological analysis, interviews with eight participants served as the primary data collection source. A phenomenological methodology was used to explore veterans’ perceptions of the transition experience to the community college and utilizing college services through the lens of Rendón’s (1994) validation theory. Six major themes emerged, including a positive view of college resources, recognizing feeling misunderstood or isolated, seeking community, a challenging enrollment process, possessing mission-driven goals, and pursuing ways to mitigate needs

Oral History Interview: Donivan E. Adams

Mr. Adams gives a detailed history of his professional career in this interview, a career in which he has had many different responsibilities. Adams talks about how he was recruited by the West Virginia State Police early in his life, when he was making a living by teaching and driving a cream truck. Through the discussion of this part of his career, some of the history of the West Virginia State Police is revealed, including the story of the development of the statewide driver\u27s education program. After working for several years as a police and intelligence officer, Mr. Adams was appointed warden of the West Virginia State Penitentiary at Moundsville. Mr. Adams describes what the material conditions at the prison were like when he began his post, and then discusses in detail the reforms which he personally implemented. He also describes in great detail what it was like to be a prison warden, which generates an image of the day-to-day workings of the state penitentiary. Toward the end of the interview, Mr. Adams talks about his life after leaving the warden position, describing his work with the Red Cross and his political aspirations.https://mds.marshall.edu/oral_history/1135/thumbnail.jp

Efforts toward understanding dietary components and the reproductive behaviors and limitations of the giant panda (Ailuropoda melanoleuca)

Preservation of giant pandas, Ailuropoda melanoleuca, is a worldwide concern. This study was designed to examine dietary and reproductive challenges associated with panda management. Phytoestrogens are natural plant compounds that mimic estrogen and often negatively impact mammalian reproduction. Phytoestrogens in bamboo, the panda’s primary food source, is unknown. Here, estrogen radioimmuno- and receptor-binding assays revealed estrogenic activity in three species of Phyllostachys bamboo. These results present indirect evidence of phytoestrogenic mimics in bamboo, but their relevance is still unknown. Studies were also conducted to observe panda reproductive behaviors in an attempt to augment the use of an artificial vagina (AV) for semen collection. A preliminary study confirmed the panda could differentiate between estrus urine and a water ‘control.’ However, when estrus urine was placed on the AV as an attractant, the subject didn’t approach the AV. Further investigation of dietary challenges and reproductive alternatives are needed to substantiate these findings

Neural Biosensor Probes for Simultaneous Electrophysiological Recordings, Neurochemical Measurements, and Drug Delivery with High Spatial and Temporal Resolution.

The aim of this work is to develop and validate novel neural biosensor probes for simultaneous electrophysiological and neurochemical measurements with precise, localized drug delivery. This technology has been developed to interface with the complex environment of the brain for more advanced experimental investigations at the intersections of neurophysiology, neuropathology, and neuropharmacology. The validation experiments have been conducted using relevant in vivo testbeds as a foundation for future work to more fully understand and treat neurological disorders. Chapter II presents a multimodal probe that enables concurrent detection of choline, recording of electrophysiology, and localized drug delivery. Central to this work is the development of selective electrodeposition methods for enzyme immobilization and polymerization on individual microelectrode sites that more closely approach the scale of neurons than currently reported neural biosensors. Multiple neurotransmitter systems are implicated in the pathophysiology of schizophrenia, Alzheimer’s disease, Parkinson’s disease, and other neurological disorders, yet the direct relationships remain unclear. The ability to simultaneously monitor multiple chemical signals concurrently with electrophysiology and integrated pharmacological manipulation can serve as a useful tool to further these investigations. Chapter III further extends the probe capabilities to include glutamate sensing concurrent with choline sensing, electrophysiology recordings, and drug delivery. Electrochemical biosensors are commonly used to record neurotransmitter dynamics, yet there remains no standard calibration media or procedure. Differences in calibration procedures can impact reported performance making the interpretation of in vivo difficult. Chapter IV aims to improve our ability to interpret in vivo neurochemical recordings by investigating the influence of calibration media on performance characteristics of amperometric biosensors. Bridging the electrophysiological and neurochemical domains with sufficient fidelity, resolution, sensitivity, and selectivity can provide novel insights into neurophysiology that lead to improved therapeutic approaches for treating neurologicalvdisorders.PhDBiomedical EngineeringUniversity of Michigan, Horace H.

Formation of Jets and Equatorial Superrotation on Jupiter

The zonal flow in Jupiter's upper troposphere is organized into alternating retrograde and prograde jets, with a prograde (superrotating) jet at the equator. Existing models posit as the driver of the flow either differential radiative heating of the atmosphere or intrinsic heat fluxes emanating from the deep interior; however, they do not reproduce all large-scale features of Jupiter's jets and thermal structure. Here it is shown that the difficulties in accounting for Jupiter's jets and thermal structure resolve if the effects of differential radiative heating and intrinsic heat fluxes are considered together, and if upper-tropospheric dynamics are linked to a magnetohydrodynamic (MHD) drag that acts deep in the atmosphere. Baroclinic eddies generated by differential radiative heating can account for the off-equatorial jets; meridionally propagating equatorial Rossby waves generated by intrinsic convective heat fluxes can account for the equatorial superrotation. The zonal flow extends deeply into the atmosphere, with its speed changing with depth, up to depths at which the MHD drag acts. The theory is supported by simulations with an energetically consistent general circulation model of Jupiter's outer atmosphere. A simulation that incorporates differential radiative heating and intrinsic heat fluxes reproduces Jupiter's observed jets and thermal structure and makes testable predictions about as-yet unobserved aspects thereof. A control simulation that incorporates only differential radiative heating but not intrinsic heat fluxes produces off-equatorial jets but no equatorial superrotation; another control simulation that incorporates only intrinsic heat fluxes but not differential radiative heating produces equatorial superrotation but no off-equatorial jets.Comment: 23 pages, 10 figure

Nobush

Nobush is a piece for chamber orchestra. The form is sonata-allegro and may be divided into the following parts: Introduction mm. 1-5, Exposition mm. 6-37, Development mm. 38-69, Recapitulation mm. 70-95. Emphasis is on motivic development of the short theme and the sonority of the perfect fifth. Tonal centers of work are G and C#, the tritone. The rhythm and tempo of the piece are slow and sombre with few deviations. Nobush derives its name and solemn character from a legendary Scandinavian dwarf who brought sadness and gloom wherever he went.California State University, Northridge. Department of Music
