NFL Betting Market Efficiency: Finding a Profitable Betting Strategy

This paper uses pregame spread data to attempt to analyze the efficiency of the NFL betting market. I look at hot hand betting, performance during prime-time games, home field advantage, and favorites to test for inefficiencies in the market, thereby uncovering a profitable betting strategy. Using OLS regression analysis, I find no evidence of a profitable betting strategy betting on teams on streaks or home underdogs. However, my results suggest that it may be profitable to bet on the home team in prime-time games, regardless of their favorite or underdog status

Social Functioning in Children with Brain Insult

Social dysfunction is commonly reported by survivors of brain insult, and is often rated as the most debilitating of all sequelae, impacting on many areas of daily life, as well as overall quality of life. Within the early brain insult (EBI) literature, physical and cognitive domains have been of primary interest and social skills have received scant attention. As a result it remains unclear how common these problems are, and whether factors predictive of recovery (insult severity, lesion location, age at insult, environment) in other functional domains (motor, speech, cognition) also contribute to social outcome. This study compared social outcomes for children sustaining EBI at different times from gestation to late childhood to determine whether EBI was associated with an increased risk of problems. Children with focal brain insults were categorized according to timing of brain insult: (i) Congenital (n = 38): EBI: first–second trimester; (ii) Perinatal (n = 33); EBI: third trimester to 1-month post-natal; (iii) Infancy (n = 23): EBI: 2 months–2 years post-birth; (iv) Preschool (n = 19): EBI: 3–6 years; (v) Middle Childhood (n = 31): EBI: 7–9 years; and (vi) Late Childhood (n = 19): EBI: after age 10. Children's teachers completed questionnaires measuring social function (Strengths and Difficulties Questionnaire, Walker–McConnell Scale of Social Competence and School Adjustment). Results showed that children with EBI were at increased risk for social impairment compared to normative expectations. EBI before age 2 years was associated with most significant social impairment, while children with EBI in the preschool years and in late childhood recorded scores closer to normal. Lesion location and laterality were not predictive of social outcome, and nor was social risk. In contrast, presence of disability (seizures) and family function were shown to contribute to aspects of social function

Local Arboreal Representations

Let K be a field complete with respect to a discrete valuation v of residue characteristic p. Let f(z)∈K[z] be a separable polynomial of the form z[superscript ℓ]−c. Given a∈K, we examine the Galois groups and ramification groups of the extensions of K generated by the solutions to fn(z)=a. The behavior depends upon v(c), and we find that it shifts dramatically as v(c) crosses a certain value: 0 in the case p∤ℓ, and −p/(p−1) in the case p=ℓ

Inhaled corticosteroids versus long-acting beta -agonists for chronic obstructive pulmonary disease (Review).

Long-acting beta(2)-agonists and inhaled corticosteroids can be used as maintenance therapy by patients with moderate to severe chronic obstructive pulmonary disease. These interventions are often taken together in a combination inhaler. However, the relative added value of the two individual components is unclear

Spatial sampling of the thermospheric vertical wind field at auroral latitudes

Results are presented from two nights of bistatic Doppler measurements of neutral thermospheric winds using Fabry!Perot spectrometers at Mawson and Davis stations in Antarctica. A scanning Doppler imager (SDI) at Mawson and a narrow-field Fabry-Perot spectrometer (FPS) at Davis have been used to estimate the vertical wind at three locations along the great circle joining the two stations, in addition to the vertical wind routinely observed above each station. These data were obtained from observations of the 630.0 nm airglow line of atomic oxygen, at a nominal altitude of 240 km. Low!resolution all-sky images produced by the Mawson SDI have been used to relate disturbances in the measured vertical wind field to auroral activity and divergence in the horizontal wind field. Correlated vertical wind responses were observed on a range of horizontal scales from ~150 to 480 km. In general, the behavior of the vertical wind was in agreement with earlier studies, with strong upward winds observed poleward of the optical aurora and sustained, though weak, downward winds observed early in the night. The relation between vertical wind and horizontal divergence was seen to follow the general trend predicted by Burnside et al. (1981), whereby upward vertical winds were associated with positive divergence and vice versa; however, a scale height approximately 3–4 times greater than that modeled by NRLMSISE-00 was required to best fit the data using this relation

Compositional changes of light hydrocarbons during migration through overburden : proxy for assessing potential leakage from Geological Carbon Storage

Light hydrocarbon compositions evolve during migration through geologic media, but our understanding of geochemical alteration is limited because of the challenges with analyzing fluids in the sedimentary column. Understanding fluid evolution is timely because of the possibility of upward fluid migration from Geologic Carbon Storage (GCS) operations. The first goal of this research is to identify to what extent hydrocarbons migrate to shallower intervals. Addressing this goal is challenging because microbial hydrocarbon production commonly occurs in the near-surface. Light hydrocarbon compositions are investigated in soil gas above a hydrocarbon system and in offshore sediment above a gas chimney. In both cases, the fluid sources are interpreted as microbial in origin. However, these geochemical datasets are relevant to attributing future light hydrocarbon seeps and anomalies above GCS sites. The second goal is to quantify alteration processes when migration has occurred. I hypothesize that phase changes and sorption are the primary alteration processes. To test this hypothesis, I numerical simulation these processes to compare with field datasets that are interpreted as migration. The models indicate that sorption has the most significant influence on light hydrocarbons, although more lab work is warranted to improve these models. Forward models of CO₂ migration show that phase changes are important in attenuating CO₂ and can be identified with noble gas compositions. This conclusion may be valuable to determining the source of CO₂ anomalies above GCS sites.Geological Science

Design and Implementation of an Instruction Set Architecture and an Instruction Execution Unit for the REZ9 Coprocessor System

While the use of RNS has provided groundbreaking theory and progress in this field, the applications still lack viable testing platforms to test and verify the theory. This Thesis outlines the processing of developing an instruction set architecture (ISA) and an instruction execution unit (IEU) to help make the first residue based general processor a viable testing platform to address the mentioned problems. Consider a 32-bit ripple adder. The delay on this device will be 32N where N is the delay for each adder to complete its operation. The delay of this process is due to the need to propagate each carry signal generated by each adder to the next one. This was solved by the creation of the Carry Look Ahead (CLA), which could drastically reduce the delay by 2/3. However, like the ripple adder, the CLA is still encumbered by propagation delay. A residue processor in the same situation would have a delay of 1N regardless of bit size since carry propagation is no longer a concern. The Thesis discusses how prior challenges using residue number systems in computers has been overcome by Digital System Research (DSR)
