The Design of a Tagged Photon Spectrometer and its Use in Measuring the Photodisintegration of the Deuteron in the Energy Range 80-135 MeV

The work described in this thesis was conducted at the Kelvin Laboratory, University of Glasgow and at the Institut Fur Kernphysik der Universitat Mainz, between October 1982 and January 1986. Presented in this thesis are new results on the photodisintegration of the deuteron in the photon energy range 80 - 135 MeV, the intermediate energy range, using tagged bremsstrahlung photons. This thesis also describes the design and construction details of the tagged photon spectrometer employed for the above measurements. The tagged photon spectrometer was specifically designed for the 180 MeV electron racetrack microtron at the Institut Fur Kernphysik der Universitat Mainz, MAMI - A. The system was designed to enable bremsstrahlung photons in the energy range 80 - 174 MeV to be tagged at fluxes of up to 5 x 10e7s-1. Using the tagged photon spectrometer the differential cross section for the reaction D(gamma,rho)n was measured for the photon energies in the range 80 - 135 MeV, and for the angular range thetap = 50 - 130 the center of mass proton emission angle. Results are presented for the selected photon energies of 87, 95, 104, 113, 122 and 128 MeV for the complete angular range. Measurements were performed simultaneously, for the quoted energy and angular ranges. The cross section information was then extracted using a purpose written data analysis program, which used time correlations and kinematic constraints to identify deuteron type events. Comparisons were made between several well known theoretical descriptions of deuteron photodisintegration and the presented data. The magnitude of the errors assigned to the measurements prevented any reliable indication in favour of one approach over another. However, the possibilities of a measurement of the cross section to an accuracy of better than 5 % look very promising using this apparatus

An Analysis of RF Transfer Learning Behavior Using Synthetic Data

Transfer learning (TL) techniques, which leverage prior knowledge gained from data with different distributions to achieve higher performance and reduced training time, are often used in computer vision (CV) and natural language processing (NLP), but have yet to be fully utilized in the field of radio frequency machine learning (RFML). This work systematically evaluates how radio frequency (RF) TL behavior by examining how the training domain and task, characterized by the transmitter/receiver hardware and channel environment, impact RF TL performance for an example automatic modulation classification (AMC) use-case. Through exhaustive experimentation using carefully curated synthetic datasets with varying signal types, signal-to-noise ratios (SNRs), and frequency offsets (FOs), generalized conclusions are drawn regarding how best to use RF TL techniques for domain adaptation and sequential learning. Consistent with trends identified in other modalities, results show that RF TL performance is highly dependent on the similarity between the source and target domains/tasks. Results also discuss the impacts of channel environment, hardware variations, and domain/task difficulty on RF TL performance, and compare RF TL performance using head re-training and model fine-tuning methods.Comment: arXiv admin note: substantial text overlap with arXiv:2206.0832

Herbal Medicine for Hot Flushes Induced by Endocrine Therapy in Women with Breast Cancer: A Systematic Review and Meta-Analysis

Objective. This systematic review was conducted to evaluate the clinical effectiveness and safety of herbal medicine (HM) as an alternative management for hot flushes induced by endocrine therapy in breast cancer patients. Methods. Key English and Chinese language databases were searched from inception to July 2015. Randomized Controlled Trials (RCTs) evaluating the effects of HM on hot flushes induced by endocrine therapy in women with breast cancer were retrieved. We conducted data collection and analysis in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. Statistical analysis was performed with the software (Review Manager 5.3). Results. 19 articles were selected from the articles retrieved, and 5 articles met the inclusion criteria for analysis. Some included individual studies showed that HM can relieve hot flushes as well as other menopausal symptoms induced by endocrine therapy among women with breast cancer and improve the quality of life. There are minor side effects related to HM which are well tolerated. Conclusion. Given the small number of included studies and relatively poor methodological quality, there is insufficient evidence to draw positive conclusions regarding the objective benefit of HM. Additional high quality studies are needed with more rigorous methodological approach to answer this question

An assessment of the Hua Oranga outcome instrument and comparison to other outcome measures in an intervention study with Maori and Pacific people following stroke

The Hua Oranga instrument, developed for Maori people with mental illness, showed good responsiveness and adequate psychometric properties in Maori and Pacific people after stroke. Its simplicity, relative brevity, minimal cost and adequate psychometric properties should favour its use in future studies with both Maori and Pacific people. Suggestions are made for refinements to the measure. These should be tested in a new population before Hua Oranga is recommended for general use in a clinical setting. Abstract Aim Health outcomes research for Maori has been hampered by the lack of adequately validated instruments that directly address outcomes of importance to Maori, framed by a Maori perspective of health. Hua Oranga is an outcome instrument developed for Maori with mental illness that uses a holistic view of Maori health to determine improvements in physical, mental, spiritual and family domains of health. Basic psychometric work for Hua Oranga is lacking. We sought to explore the psychometric properties of the instrument and compare its responsiveness alongside other, more established tools in an intervention study involving Maori and Pacific people following acute stroke. Method Randomised 2x2 controlled trial of Maori and Pacific people following acute stroke with two interventions aimed at facilitating self-directed rehabilitation, and with follow-up at 12 months after randomisation. Primary outcome measures were the Physical Component Summary (PCS) and Mental Component Summary (MCS) of the Short Form 36 (SF36) at 12 months. Hua Oranga was used as a secondary outcome measure for participants at 12 months and for carers and whanau (extended family). Psychometric properties of Hua Oranga were explored using plots and correlation coefficients, principal factors analysis and scree plots. Results 172 participants were randomised, of whom 139 (80.8%) completed follow-up. Of these, 135 (97%) completed the Hua Oranga and 117 (84.2%) completed the PCS and MCS of the SF36. Eighty-nine carers completed the Hua Oranga. Total Hua Oranga scores and PCS improved significantly for one intervention group but not the other. Total Hua Oranga scores for carers improved significantly for both interventions. Total Hua Oranga score correlated moderately with the PCS (correlation coefficient 0.55, p<0.001). Factor analysis suggested that Hua Oranga measures two and not four factors; one 'physical-mental' and one 'spiritual-family'. Conclusion The Hua Oranga instrument, developed for Maori people with mental illness, showed good responsiveness and adequate psychometric properties in Maori and Pacific people after stroke. Its simplicity, relative brevity, minimal cost and adequate psychometric properties should favour its use in future studies with both Maori and Pacific people. Suggestions are made for refinements to the measure. These should be tested in a new population before Hua Oranga is recommended for general use in a clinical setting

Regionalizing Government in Maine: Opportunities for the Future

In keeping with his promise to make government work better for the people of Maine, Governor Angus King commissioned the Task Force on Regional Options for Better Government. The Governor charged the task force with recommending some alternative regional arrangements for the delivery of government services currently provided by state or local government. The task force evaluated three services in which regionalism offered some advantages: economic development; demand response transportation; and municipal management information systems

Bending properties and ash content of fetal cranial bone

Forty-five specimens of fetal cranial bone ranging in estimated gestational age from 25-40 weeks were tested in three-point bending. Five specimens of a six-year-old calvarium were tested for comparative purposes. The elastic modulus of each specimen was derived from the bending stiffness and geometrical property data. Following mechanical testing, each specimen was oven-dried and ashed to a constant weight. Ash content was determined as the ratio of ash weight to dry specimen weight. The results indicate that the ash content of fetal cranial bone increases significantly (from 50% to 68%) with increasing gestational age. (The elastic modulus of fetal cranial bone significantly increases with increasing ash content.) However, the ash content of the term fetal cranial bone or the six-year-old cranial bone is not significantly different from that found in the adult. These results are discussed in relation to a structural hypothesis for increasing cranial bone stiffness with increasing maturity.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/24497/1/0000773.pd
