A Superfield for Every Dash-Chromotopology
The recent classification scheme of so-called adinkraic off-shell
supermultiplets of N-extended worldline supersymmetry without central charges
finds a combinatorial explosion. Completing our earlier efforts, we now
complete the constructive proof that all of these trillions or more of
supermultiplets have a superfield representation. While different as
superfields and supermultiplets, these are still super-differentially related
to a much more modest number of minimal supermultiplets, which we construct
herein.Comment: 13 pages, integrated illustration

The role of Turkish percussion in the history and development of the orchestral percussion section
The fascination of eighteenth century Western composers with the Eastern percussion instruments of the Turks was the impetus behind the initial use of percussion instruments in the orchestra. Consequently, the era beginning in the late eighteenth-century when percussion instruments were first included deserves reexamination. The objectives of this monograph include the examination of the manner in which composers first utilized Turkish percussion (excluding kettledrums) in the orchestra. This study then investigates the subsequent history of these instruments and manner in which composers utilized them, leading to their recognition as musical instruments in their own right. The findings of this study provide a resource for both performers and conductors who seek to recreate authentic performances of music from that era. Research methods included the examination of existing primary and largely secondary sources that included musical scores and newspaper articles of the period. The organology of these instruments and their performance practices were studied, aided by iconographical evidence of the instruments and their performance. Salient findings of this study were that the percussion instruments first incorporated into the late eighteenth-century and early nineteenth-century orchestra consisted of the bass drum, cymbals, and triangle. The Turkish crescent and tambourine was also occasionally added. Some of these instruments entered the orchestra with a specialized performance practice. The bass drum, for example, was struck by one hand on the side of the drum\u27s head with a wooden beater; the other hand struck the opposite head with a switch most often made of twigs, called a ruthe. Orchestral composers such as Haydn, Mozart, and Beethoven were among the first to incorporate Turkish percussion instruments, using them as a homogeneous group that produced a characteristic tone color through the simultaneous playing of each instrument, reminiscent of their use in military bands. Each Turkish percussion instrument experienced changes in design that resulted in a more independent use of each instrument. Nineteenth-century composers such as Berlioz wrote parts for percussion and timpani integral to the harmonic and textural structure of their orchestral compositions. Percussion instruments have since become a frequent focal point of orchestration
Incorporating Punctuation Into the Sentence Grammar: A Lexicalized Tree Adjoining Grammar Perspective
Punctuation helps us to structure, and thus to understand, texts. Many uses of punctuation straddle the line between syntax and discourse, because they serve to combine multiple propositions within a single orthographic sentence. They allow us to insert discourse-level relations at the level of a single sentence. Just as people make use of information from punctuation in processing what they read, computers can use information from punctuation in processing texts automatically. Most current natural language processing systems fail to take punctuation into account at all, losing a valuable source of information about the text. Those which do mostly do so in a superficial way, again failing to fully exploit the information conveyed by punctuation. To be able to make use of such information in a computational system, we must first characterize its uses and find a suitable representation for encoding them.
The work here focuses on extending a syntactic grammar to handle phenomena occurring within a single sentence which have punctuation as an integral component. Punctuation marks are treated as full-fledged lexical items in a Lexicalized Tree Adjoining Grammar, which is an extremely well-suited formalism for encoding punctuation in the sentence grammar. Each mark anchors its own elementary trees and imposes constraints on the surrounding lexical items. I have analyzed data representing a wide variety of constructions, and added treatments of them to the large English grammar which is part of the XTAG system. The advantages of using LTAG are that its elementary units are structured trees of a suitable size for stating the constraints we are interested in, and the derivation histories it produces contain information the discourse grammar will need about which elementary units have used and how they have been combined. I also consider in detail a few particularly interesting constructions where the sentence and discourse grammars meet-appositives, reported speech and uses of parentheses. My results confirm that punctuation can be used in analyzing sentences to increase the coverage of the grammar, reduce the ambiguity of certain word sequences and facilitate discourse-level processing of the texts
Equitable Tolling of Statutory Benefit Time Limitations: A Congressional Intent Analysis
Courts toll time limitations that limit a statutory right to sue when tolling is consonant with congressional intent. Courts have left open, however, whether to extend this congressional intent analysis to toll time limitations that limit a statutory right to receive a benefit. This Comment analyzes how the United States Supreme Court\u27s 1988 decision in INS v. Pangilinan affects the power of courts to equitably toll time limitations limiting the application period for a statutory benefit. The Comment concludes that these benefit time limitations should be tollable when they are consonant with congressional intent
