Finite domination and Novikov homology over strongly Z-graded rings
Let L be a strongly Z-graded ring, and let C be a bounded chain complex of
finitely generated L-modules. We give a homological characterisation of when C
is homotopy equivalent, over L_0, to a bounded complex of finitely generated
projective L_0-modules, generalising known results for twisted Laurent
polynomial rings.Comment: 22 pages; v2: changed example in introduction, and corrected minor

The Effects of Emotion-Focused versus Instrumental Rumination on the Provision of Social Support
Victims of negative events often report that they do not receive the expected and desired social support (e.g., Dunkel-Schetter, 1984). The current study investigated the impact of two types of victim rumination and gender role expectations on support provision and receipt. Using a 2 (Instrumental vs. Emotion-Focused Rumination) x 2 (Victim Gender) x 2 (Participant Gender) between-subjects factorial design, 136 undergraduate students interacted with one of four "burglary victims" for eight minutes, providing both behavioral and questionnaire data. Results suggest that instrumental ruminators receive more support than emotion-focused ruminators. Women provided more support to victims than did men. Additionally, male victims' coping was evaluated more positively than female victims' coping, regardless of rumination type
Flight determined lift and drag characteristics of an F-8 airplane modified with a supercritical wing with comparison to wind-tunnel results
Flight measurements obtained with a TF-8A airplane modified with a supercritical wing are presented for altitudes from 7.6 kilometers (25,000 feet) to 13.7 kilometers (45,000 feet), Mach numbers from 0.6 to 1.2, and Reynolds numbers from 0.8 x 10 to the 7th power to 2.3 x 10 to the 7th power. Flight results for the airplane with and without area-rule fuselage fairings are compared. The techniques used to determine the lift and drag characteristics of the airplane are discussed. Flight data are compared with wind-tunnel model results, where applicable
Association Between Proton Pump Inhibitor Use & Dementia: A Two-Fold Approach
An observational study of data derived from the German Study on Aging, Cognition and Dementia indicated that proton pump inhibitor use was associated with dementia risk (Benmassaoud, McDonald, & Lee, 2016). The purpose of this study is to explore a two-fold approach between proton pump inhibitor use and dementia. This two-fold approach will first investigate the association between dementia and proton pump inhibitor use and secondly, the proposed pathophysiology behind it. This approach to proton pump inhibitor use and dementia will allow for providers to utilize the association and make decisions to avoid chronic proton pump inhibitor use in effort to reduce or prevent dementia. Research methods include reviewing peer reviewed journal that were obtained from Pubmed, ClinicalKeyand PsycINFO. Gomm et al. (2016) found that their study participants prescribed proton pump inhibitors had a significant increase in risk of dementia (HR, 1.44 [95% CI, 1.04-1.83]). Haenischet al. (2015) found that the use of proton pump inhibitor medication increased the risk of any dementia (HR 1.38, [95% CI, 1.04-1.83]) compared to no proton pump inhibitor use. Akteret al. (2015) utilized the CANTAB software which provided multiple significant findings in several different testable areas among proton pump inhibitor users. Badiolaet al. (2013) used materials and methods such as cell culture, drug treatments, analysis of amyloid-beta peptides by ELISA, mass spectrometry of amyloid-beta species, animals and treatments, brain soluble amyloid-beta extraction and western blotting to provide one-way ANOVA and t-test to report the effect of proton pump inhibitors have on amyloid-beta degeneration in mice. Jung et al. (2015) found statistical significance between chronic acid lowering agents and vitamin B12 deficiency with a hazard ratio of 1.83 [95% CI: 1.36-2.46], p-valuehttps://commons.und.edu/pas-grad-posters/1054/thumbnail.jp

Blood on the Moon: The Assassination of Abraham Lincoln
Winner of the 2001 The Lincoln Group of New York\u27s Award of Achievement
The assassination of Abraham Lincoln is usually told as a tale of a lone deranged actor who struck from a twisted lust for revenge. This is not only too simple an explanation; Blood on the Moon reveals that it is completely wrong. John Wilkes Booth was neither mad nor alone in his act of murder. He received the help of many, not the least of whom was Dr. Samuel Alexander Mudd, the Charles County physician who has been portrayed as the innocent victim of a vengeful government. Booth was also aided by the Confederate leadership in Richmond. As he made his plans to strike at Lincoln, Booth was in contact with key members of the Confederate underground, and after the assassination these same forces used all of their resources to attempt his escape. Noted Lincoln authority Edward Steers Jr. introduces the cast of characters in this ill-fated drama, he explores why they were so willing to help pull the trigger, and corrects the many misconceptions surrounding this defining moment that changed American history. After completing an acclaimed career as a research scientist at the National Institutes of Health,
Edward Steers Jr. has turned his research skills to the Lincoln assassination. He is the author of several books about the president, including The Trial. He lives in Berkeley Springs, West Virginia.

Flight-determined stability and control coefficients of the F-111A airplane
A complete set of linear stability and control derivatives of the F-111A airplane was determined with a modified maximum likelihood estimator. The derivatives were determined at wing sweep angles of 26 deg, 35 deg, and 58 deg. The flight conditions included a Mach number range of 0.63 to 1.43 and an angle of attack range of 2 deg to 15 deg. Maneuvers were performed at normal accelerations from 0.9g to 3.8g during steady turns to assess the aeroelastic effects on the stability and control characteristics. The derivatives generally showed consistent trends and reasonable agreement with the wind tunnel estimates. Significant Mach effects were observed for Mach numbers as low as 0.82. No large effects attributable to aeroelasticity were noted
