Rotating launch device for a remotely piloted aircraft

A method and apparatus for launching a remotely piloted aircraft is disclosed, wherein the aircraft is revolved about a fixed pivot point until a predetermined speed is reached whereupon the vehicle is released from the launching apparatus. The vehicle is attached to one end of a rotatable arm, the imbalance on the arm being counteracted by a counter weight attached to the opposite end. The counter weight is released from the arm at the same time as the aircraft so as to avoid structural damage to the apparatus caused by rotation in the unbalanced condition. The arm is oriented such that it rotates in a plane inclined obliquely to the local gravitational field of the launch site

Embedding Groups into Distributive Subsets of the Monoid of Binary Operations

Let X be a set and Bin(X) the set of all binary operations on X. We say that a subset of Bin(X) is a distributive set of operations if all pairs of elements are right distributive. J.Przytycki posed the question of which groups can be realized as distributive sets. The initial guess that any group may be embedded into Bin(X) for some X was complicated by an observation that if a binary operation is idempotent (a*a=a), then it commutes with every element of S. The first noncommutative subgroup of Bin(X), the symmetric group on three elements, was found in October of 2011 by Y.Berman. We show that any group can be embedded in Bin(X) for X=G (as a set). We also discuss minimality of embeddings observing that, in particular, X with six elements is the smallest set such that Bin(X) contains a non-abelian subgroup.Comment: 6 page

A Shplit Ticket, Half Irish, Half Chinay : Representations of Mixed-Race and Hybridity in the Turn-of-the-Century Theater

Charles Townsend\u27s 1889 adaptation of Harriet Beecher Stowe\u27s Uncle Tom\u27s Cabin features white actors playing light- and dark-skinned African-American characters, changing degrees of make-up as the script, stage business, or number of available players demands. Thomas Denison\u27s stage directions to his 1895 play, Patsy O\u27Wang, an Irish Farce with a Chinese Mix-Up, stipulates that the alternation of the half -Chinese, half-Irish cook between his two ethnic personas is key to this capital farce, and that a comedie use of the Chinese dialect is central to this. The Geezer (c. 1896), Joseph Herbert\u27s spoof of the popular musical, The Geisha, features white actors playing Chinese dignitaries, but also donning German and Irish accents. The white actors in these plays enact different paradigms of hybridity. The actors in Townsend\u27s Uncle Tom\u27s Cabin, a Melodrama in Five Acts embody conceptions of both mixed and unmixed African Americans, freely alternating between each. In Patsy O\u27Wang, the main character\u27s background is central to the story, and the lead actor moves between the two ethnicities by his accent, mannerisms, and politics. Racial mixing is central to the plot of The Geezer through Anglo actors who make themselves hybrid by appearing Chinese and appropriating a third accent, rather than the creation of racially mixed offspring

The Effect of High School Accounting on the Selection of College Major, Performance, Satisfaction, and Retention

The objective of this study is to examine the impact completion of a high school accounting course has on the selection of college major, academic performance in introductory accounting courses, satisfaction with one’s major, and retention. These relations are examined using data from a survey given to 208 students of various majors enrolled in the Paul College of Business and Economics at the University of New Hampshire. Multiple linear regression analyses were used to analyze the data. The results provide evidence of a significant positive relation between high school accounting and two variables: selection of college major, and performance in introduction to managerial accounting. The results also provide evidence consistent with a moderately significant relation between high school accounting and retention. The results do not show any significant relation between high school accounting and performance in introduction to financial accounting or major satisfaction. Overall, the results of this study contribute to a better understanding of the effect high school accounting can have on the development of future accounting professionals

The Importance of Seeming Earnest: Emotion Work and Leadership in Theater Worlds

Although leaders can always use formal power to establish their authority, they do so at risk of alienating group members. By studying theater workers who must establish authority without having the opportunity to establish their expertise, I find a third way of establishing authority: through emotion work that shows commitment to the group and its goals. By employing in-depth interviewing, participant observation, and qualitative content analysis, I find that stage managers establish their concern for the show and key actors by acting as emotional buffers, creating a safe psychological space, and preparing actors for the transition to performance. All of this work comes out of an emotional ideology that puts the good of the show first. Other leaders may be able to employ a similar emotional ideology to influence group members

Metachronous Intraductal Papillary Neoplasm of the Bile Duct and Intraductal Papillary Mucinous Neoplasm of the Pancreas in a Patient Diagnosed With Mucinous Adenocarcinoma.

Intraductal papillary neoplasm of the bile duct (IPNB) is a rare biliary tumor, which shares some radiologic and histologic similarities with pancreatic intraductal papillary mucinous neoplasm (IPMN). IPNB is a recognized precursor lesion of invasive adenocarcinoma. We present a case of metachronous IPNB and IPMN lesions in a patient with mucinous adenocarcinoma of the pancreas who presented with jaundice and abdominal pain. The patient was treated with surgery and adjuvant chemotherapy

Outer trapped surfaces are dense near MOTSs

We show that any vacuum initial data set containing a marginally outer trapped surface S and satisfying a "no KIDs" condition can be perturbed near S so that S becomes strictly outer trapped in the new vacuum initial data set. This, together with the results in [9], gives a precise sense in which generic initial data containing marginally outer trapped surfaces lead to geodesically incomplete spacetimes.Comment: 14 pages, minor rewording

A Remark on Witten Effect for QCD Monopoles in Matrix Quantum Mechanics

In a recent work (hep-th/9905198) we argued that a certain matrix quantum mechanics may describe 't Hooft's monopoles which emerge in QCD when the theory is projected to its maximal Abelian subgroup. In this note we find further evidence which supports this interpretation. We study the theory with a non-zero theta-term. In this case, 't Hooft's QCD monopoles become dyons since they acquire electric charges due to the Witten effect. We calculate a potential between a dyon and an anti-dyon in the matrix quantum mechanics, and find that the attractive force between them grows as the theta angle increases.Comment: 5 pages, revte
