An Archaeological Evaluation of Three Prehistoric Sites Upper Cibolo Creek Watershed, Kendall County, Southern Central Texas

During the summer of 1977, personnel from the Center for Archaeological Research, The University of Texas at San Antonio (UTSA), conducted archaeological test excavations at three sites along Frederick Creek in Kendall County, Texas. These sites were located in areas proposed for modification by the construction of Floodwater Retarding Structure #3 in the Upper Cibolo Creek watershed. The field work was conducted under a contract between the Center for Archaeological Research and the United States Department of Agriculture Soil Conservation Service (Purchase Order No. 40-7442-7-1212). An initial survey of the area had been conducted in February 1975, and resulted in the documentation of two historic and 17 prehistoric sites (Bass and Hester 1975). Three prehistoric sites, 41 KE 46, 41 KE 54 and 41 KE 57, were recommended for testing to evaluate their importance. To more clearly define the archaeological potential of these three sites, the investigations had two major objectives: (l) to accurately determine the horizontal and vertical extent of the cultural deposits; and (2) to evaluate these archaeological resources in terms of possible nomination to the National Register of Historic Places

41BX68: A Preshitoric Quarry-Workshop In Northern Bexar County, Texas

During late February and early March of 1978, personnel from the Center for Archaeological Research, The University of Texas at San Antonio, conducted intensive mapping and limited subsurface testing of the prehistoric quarry-workshop site of 41 BX 68. Investigations of the site, located near the intersection of FM 1604 and Elm Creek in northern Bexar County (see Fig. 1), were conducted under the terms of a contract (Purchase Order No. 40-7442-8-426) with the Soil Conservation Service. Located near proposed Floodwater Retarding Structure 11, portions of the extensive site will soon be altered or critically damaged by modification. Preliminary observations of the site indicated large areas were relatively undisturbed since the original aboriginal activity had taken place (Brown et al. 1977). Intact, relatively undisturbed concentrations of lithic debris were noted (see Fig. 2). The frequency, distribution and association of these materials were considered to be of unusual value in identifying intra-site activity areas. The intent of the current investigation was to formulate a preliminary description of the site and identify various aspects of lithic technological processes and their intra-site relationships in a prehistoric south central Texas quarry-workshop area

Investigation of Prehistoric Rockshelter and Terrace Sites Along Portions of the Salado Creek Drainage, Nothern Bexar County, Texas

During late fall and winter of 1977, personnel from the Center for Archaeological Research, The University of Texas at San Antonio (UTSA), conducted limited test excavations and controlled surface collections along portions of the Salado Creek drainage in northern Bexar County (Fig. I). Four specific areas were examined, as they were soon to be inundated or critically altered by proposed floodwater retarding structures. The sites in these locations had previously been identified and recommended for further work by Hester et al. (1974). During field operations, the areas of Floodwater Retarding Structures 3, 6, 10 and 15 were investigated. A total of four terrace sites, two small rockshelters and two rockshelter complexes were tested. Of the shelters, one complex and one individual shelter, both previously unrecorded, were discovered in the immediate vicinity of the retarding structures during the course of testing operations. Testing was concentrated in the immediate vicinities of Mud Creek, Panther Springs Creek and portions of the main channel of Salado Creek

A Preliminary Assessment of Archaeological Resources at Tobins Oakwell Farm, San Antonio, Texas

A preliminary archaeological survey and assessment of the Tobins Oakwell Farm project area was conducted during August 22-24, 1977, by archaeologists from the Center for Archaeological Research, The University of Texas at San Antonio (UTSA). The work was conducted within two nearby but separate areas adjacent to Salado Creek within the city limits of San Antonio, northern Bexar County. The investigation was performed under a contract between the Center and Ford, Powell and Carson, architects and planners

Archaeological Survey of Areas Proposed for Modification in the Encino Park Development, Northern Bexar County, Texas

During late April and May of 1977, individuals from the Center for Archaeological Research, The University of Texas at San Antonio (UTSA), conducted a preliminary archaeological survey and assessment of the proposed 2500-acre Encino Park Development in northern Bexar County. The work was conducted in two phases by two different teams working during the periods of April 25-May 4 and May 16-20, 1977, although both investigated portions of the East and West Elm Creek drainages and adjacent upland areas. The archaeological assessment was carried out under contract with the Denton Development Corporation. The intent of the survey was to locate and assess archaeological sites in the Encino Park study area and to evaluate their significance before destruction or alteration occurred. Proposed developments will alter or modify major areas of the present physical topography near the Elm Creek drainages and will thus eventually disturb the local archaeological resources

Reinforcement magnitudes modulate subthalamic beta band activity in patients with Parkinson's disease

We set out to investigate whether beta oscillations in the human basal ganglia are modulated during reinforcement learning. Based on previous research, we assumed that beta activity might either reflect the magnitudes of individuals' received reinforcements (reinforcement hypothesis), their reinforcement prediction errors (dopamine hypothesis) or their tendencies to repeat versus adapt responses based upon reinforcements (status-quo hypothesis). We tested these hypotheses by recording local field potentials (LFPs) from the subthalamic nuclei of 19 Parkinson's disease patients engaged in a reinforcement-learning paradigm. We then correlated patients' reinforcement magnitudes, reinforcement prediction errors and response repetition tendencies with task-related power changes in their LFP oscillations. During feedback presentation, activity in the frequency range of 14 to 27 Hz (beta spectrum) correlated positively with reinforcement magnitudes. During responding, alpha and low beta activity (6 to 18 Hz) was negatively correlated with previous reinforcement magnitudes. Reinforcement prediction errors and response repetition tendencies did not correlate significantly with LFP oscillations. These results suggest that alpha and beta oscillations during reinforcement learning reflect patients' observed reinforcement magnitudes, rather than their reinforcement prediction errors or their tendencies to repeat versus adapt their responses, arguing both against an involvement of phasic dopamine and against applicability of the status-quo theory

DCU-Symantec at the WMT 2013 Quality Estimation Shared Task

We describe the two systems submitted by the DCU-Symantec team to Task 1.1. of the WMT 2013 Shared Task on Quality Estimation for Machine Translation. Task 1.1 involve estimating post-editing effort for English-Spanish translation pairs in the news domain. The two systems use a wide variety of features, of which the most effective are the word-alignment, n-gram frequency, language model, POS-tag-based and pseudo-references ones. Both systems perform at a similarly high level in the two tasks of scoring and ranking translations, although there is some evidence that the systems are over-fitting to the training data

DCU-Symantec submission for the WMT 2012 quality estimation task

This paper describes the features and the machine learning methods used by Dublin City University (DCU) and SYMANTEC for the WMT 2012 quality estimation task. Two sets of features are proposed: one constrained, i.e. respecting the data limitation suggested by the workshop organisers, and one unconstrained, i.e. using data or tools trained on data that was not provided by the workshop organisers. In total, more than 300 features were extracted and used to train classifiers in order to predict the translation quality of unseen data. In this paper, we focus on a subset of our feature set that we consider to be relatively novel: features based on a topic model built using the Latent Dirichlet Allocation approach, and features based on source and target language syntax extracted using part-of-speech (POS) taggers and parsers. We evaluate nine feature combinations using four classification-based and four regression-based machine learning techniques

LATE EFFECTS OF HEMATOPETIC STEM CELL TRANSPLANTATION Impact of chronic GVHD on late complications after hematopoietic cell transplantation

Current results with transplantation of marrow or blood derived hemopoietic stem cells (HCT) in patients with aplastic anemia and patients who do not develop chronic graft-versus-host disease (GVHD) show life expectancies similar to agematched controls. However, patients with advanced malignant diseases and patients who develop chronic GVHD after transplant are at risk of late disease recurrence and delayed, potentially fatal complications Infections Late infections due to bacterial, viral and fungal organisms occur most commonly in patients with chronic GVHD. Early post-transplant prophylaxis may result in an increased incidence of late infections (see e.g., acyclovir/ganciclovir and late CMV infections). It is standard practice to give prophylaxis for infections caused by Pneumocystis carinii, varicella zoster and encapsulated bacteria (and, more recently, fungal organisms) during the first year post-transplant, or longer, for patients with chronic GVHD. Airway and pulmonary disease The bronchial tree may be involved by GVHD The pathogenesis of air flow obstruction (AFO) after HCT is not fully understood Progressive bronchiolitis obliterans has been reported to occur in 10% of all patients with chronic GVHD [6] from 3 months to 2 years after HCT. Clinical and pathological findings are similar to those seen after lung or heart-lung transplants A recent analysis of results in 6523 patients transplanted at FHCRC revealed 51 cases of bronchiolitis obliterans organizing pneumonia (BOOP), all but two after allogeneic transplants. BOOP was diagnosed at 5 Á/2,819 (median 108) days after HCT. The disease was significantly associated with acute and chronic GVHD. The disease progressed in 22% of patients and resolved or was stable in the remaining patient
