CENTERS OF DOMESTICATION FOR CHINESE, SPANISH, AND BEANCAP SNAP BEAN POPULATIONS

INTRODUCTION: Snap beans were primarily developed in Europe after the Columbian Exchange through selection for low fiber pods, thicker pod walls, and pod stringlessness (Myers & Baggett, 1999). Abundant evidence supports separate domestications of dry beans in the Andean and Mesoamerican centers, and the best available evidence suggests that snap beans were derived from dry bean from both centers, although the majority descend from the Andean gene pool (Gepts, 1998). While most snap beans were developed in Europe, they are not exclusively found there. Snap beans may have also been developed in China, and there is evidence that at least one bean with low fiber pod traits may have been developed by Native Americans, viz. ‘Trail of Tears.’ Three unique bean populations from China, Spain, and North America have the potential to shed light on the broader development of snap beans and their dissemination pathways out of the Americas using modern molecular tools. The first of these populations is an uncatalogued collection of Chinese snap beans assembled from a trip in 1991 by Michael Dickson (Cornell Univ.) consisting of 58 genotypes. The second consists of a selection of 11 Spanish genotypes from the Misión Biológica de Galicia – CSIC (Pontevedra, Spain) collection. These are a subset of lines selected from this collection that possess edible pod traits (de Ron, personal communication). The last population, the BeanCAP diversity panels, consists 149 snap beans mostly from commercial bean lines in North America and Europe

Ten years of computer forensic tool testing

Barbara Guttman, James R. Lyle and Richard Ayers give an overview of the Computer Forensic Tool Testing project at the National Institute of Standards and Technology, setting out the test procedures, criteria and test data sets for computer forensic software tools, together with a brief illustration of some of the failures that they encounter that can affect digital evidence

Carter-Payne homomorphisms and Jantzen filtrations

We prove a q-analogue of the Carter-Payne theorem in the case where the differences between the parts of the partitions are sufficiently large. We identify a layer of the Jantzen filtration which contains the image of these Carter-Payne homomorphisms and we show how these homomorphisms compose.Comment: 30 page

Irrigating Alfalfa in South Dakota

Alfalfa performs admirably an irrigated crop in South Dakota-so well that it is often neglected. When given attention, it can realistically maintain irrigated yields of 6 to 7 TIA each year in most of South Dakota where 1 to 2 T are produced on dryland. Irrigated land that will produce 100-130 bu corn will produce 5-7 T alfalfa. On poorer irrigated land that produces 50-70 hu corn, one can expect 3-5 T alfalfa. Alfalfa has higher water requirements for peak yields than most other crops. It may not reach its full potential yield in any part of the stale without irrigation. Alfalfa is produced on 2.2 million acres dryland and irrigated land combined) in every county in South Dakota. By contrast, even when corn is irrigated, it is adapted to only about two thirds of the slate. If the marketing problems of transportation and fluctuating prices are overcome, alfalfa could become the state\u27s number one irrigated crop

The New Media Writing Prize Special Collection

This article introduces the New Media Writing Prize (NMWP) special collection (https://www.webarchive.org.uk/en/ukwa/collection/2912) created on behalf of the six UK Legal Deposit Libraries and hosted by the UK Web Archive. It is divided into two sections, presenting the perspectives of the archivists and the organizers of the prize respectively. The first section outlines the scope of the collection and how it fits within the wider collecting activities of the libraries. It explains the methodology and workflows behind building the collection, with a special focus on the quality assurance aspect of the process, and on what constitutes a ‘good copy’ in the context of complex digital narratives. Furthermore, it touches on the history of the collaborations between the British Library and digital writing communities, which resulted in numerous workshops, events, residencies and ultimately the creation of this collection. The second section presents the history of the Prize from the point of view of its organizers, highlighting its evolution through the years and plans for the future

West Nile Virus–associated Flaccid Paralysis Outcome

We report 1-year follow-up data from a longitudinal prospective cohort study of patients with West Nile virus–associated paralysis. As in the 4-month follow-up, a variety of recovery patterns were observed, but persistent weakness was frequent. Respiratory involvement was associated with considerable illness and death
