Preliminary Cultural Resources Investigations for the Pharr-Reynosa International Bridge, Hidalgo County, Texas

Archeological, archival, and geomorphologic investigations were conducted for the proposed Pharr-Reynosa International Bridge Project in Hidalgo County, Texas, by Prewitt and Associates, Inc. from October 12-27, 1992. The purposes of these investigations were to locate and record any cultural resources within the project area, determine their eligibility for listing on the National Register of Historic Places and designation as State Archeological Landmarks, and to provide an overview of the Holocene geomorphic history of the project area. The geomorphic history of the project area suggests that the Rio Grande has experienced continuous channel aggradation from the end of the Pleistocene to ca. 1000 B.P. Climatic changes and diminishing sediment loads led to channel incision around 1000 B.P., forming a low late Holocene terrace and resulting in increased sinuosity and a decreased channel width-to-depth ratio. The investigations included a stratified sample survey of approximately 162 hectares (400 acres) and the excavation of 16 backhoe trenches and 14 shovel tests. A total of 10 sites, consisting of 10 historic and 2 prehistoric components, were documented. Six standing architectural properties, each consisting of a structure or groups of structures, also were documented. Four of the sites (41HG153, 41HG155, 41HG156, and 41HG158) are considered to be potentially eligible for listing on the National Register of Historic Places and for designation as State Archeological Landmarks. Two of the architectural properties - the Carmichael and Sorenson farmsteads - also may be eligible for listing on the National Register. The four potentially eligible sites consist of four historic and two prehistoric components. The historic components date from the Texas Republic period to the early twentieth century, representing the establishment and development of the EI Capote Ranch community. The two prehistoric components (41HG153 and 41HG158), of which only 41HG153 is potentially eligible, represent Late Prehistoric and unknown prehistoric components, respectively

International Trade in Telecommunication Services: A Cross Sectional Gravity Regression

The gravity model has been successful in measuring the effects of institutions, trade barriers, and other characteristics on trade in goods. Kimura and Lee [2004] find the gravity model is also suitable for measuring trade in services. The Organization for Economic Co-Development [2009a] develop gravity models for pilot service sectors such as construction, computer, professional, and telecommunication services. The purpose of this paper is to extend the findings of the OECD paper for telecommunication services. The paper finds that a 10 percent increase in distance between countries will decrease imports by 11.77 percent. Imports of telecommunication services are influenced by sharing a common language, EU membership, but no relationship exists for sharing a common border. This paper also shows that countries with higher output will import more services and that the sector level of trade restrictiveness negatively effects service imports. The paper concludes with a survey of previous international negotiations on pro-competitive regulation of the telecommunications market

Astrochemical confirmation of the rapid evolution of massive YSOs and explanation for the inferred ages of hot cores

Aims. To understand the roles of infall and protostellar evolution on the envelopes of massive young stellar objects (YSOs). Methods. The chemical evolution of gas and dust is traced, including infall and realistic source evolution. The temperatures are determined self-consistently. Both ad/desorption of ices using recent laboratory temperature-programmed-desorption measurements are included. Results. The observed water abundance jump near 100 K is reproduced by an evaporation front which moves outward as the luminosity increases. Ion-molecule reactions produce water below 100 K. The age of the source is constrained to t \~ 8 +/- 4 x 10^4 yrs since YSO formation. It is shown that the chemical age-dating of hot cores at ~ few x 10^3 - 10^4 yr and the disappearance of hot cores on a timescale of ~ 10^5 yr is a natural consequence of infall in a dynamic envelope and protostellar evolution. Dynamical structures of ~ 350AU such as disks should contain most of the complex second generation species. The assumed order of desorption kinetics does not affect these results.Comment: Accepted by A&A Letters; 4 pages, 5 figure

Rudy Vallee: Franco-American and Man from Maine

The Vallee family, like others that migrated from Quebec to New England, was gradually Americanized. Hubert “Rudy ” Vallee, shaped by this process of Americanization, nevertheless maintained a lifelong pride in his Franco-American roots. Throughout his long and successful career, Vallee also retained a strong affection for his native state, his fellow Mainers, and the University of Maine, which he put on the map with his hit recording of the “Stein Song. ” Rudy’s loyalty to his roots and native soil is reflected in his final resting place: the Franco-American St. Hyacinthe s Cemetery at Westbrook, in the State of Maine

Reflections on Tiles (in Self-Assembly)

We define the Reflexive Tile Assembly Model (RTAM), which is obtained from the abstract Tile Assembly Model (aTAM) by allowing tiles to reflect across their horizontal and/or vertical axes. We show that the class of directed temperature-1 RTAM systems is not computationally universal, which is conjectured but unproven for the aTAM, and like the aTAM, the RTAM is computationally universal at temperature 2. We then show that at temperature 1, when starting from a single tile seed, the RTAM is capable of assembling n x n squares for n odd using only n tile types, but incapable of assembling n x n squares for n even. Moreover, we show that n is a lower bound on the number of tile types needed to assemble n x n squares for n odd in the temperature-1 RTAM. The conjectured lower bound for temperature-1 aTAM systems is 2n-1. Finally, we give preliminary results toward the classification of which finite connected shapes in Z^2 can be assembled (strictly or weakly) by a singly seeded (i.e. seed of size 1) RTAM system, including a complete classification of which finite connected shapes be strictly assembled by a "mismatch-free" singly seeded RTAM system.Comment: New results which classify the types of shapes which can self-assemble in the RTAM have been adde

Innovating While Small

Re-think it: Libraries for a New Age is a national conference that brings together academic, public and K-12 librarians, administrators, technologists, architects, designers, furniture manufacturers, and educators. Participants gathered to collectively re-think the increasingly important role libraries play in the communities they serve. The conference was held January 8-10, 2018 at the University of Texas and other locations in Austin. In its second edition, Re-think it 2018 is co-hosted by The UT Libraries, the Austin Public Library, the Austin Community College Library Services, and seven additional local library partners.UT Librarie

Force induced triple point for interacting polymers

We show the existence of a force induced triple point in an interacting polymer problem that allows two zero-force thermal phase transitions. The phase diagrams for three different models of mutually attracting but self avoiding polymers are presented. One of these models has an intermediate phase and it shows a triple point but not the others. A general phase diagram with multicritical points in an extended parameter space is also discussed.Comment: 4 pages, 8 figures, revtex
