MODIS Composite Based Maps of East Antarctic Fast Ice Coverage
No full textProgress Code: completedMaps of East Antarctic landfast sea-ice extent, generated from approx. 250,000 1 km visible/thermal infrared cloud-free MODIS composite imagery (augmented with AMSR-E 6.25-km sea-ice concentration composite imagery when required).<br/><br/>Because of imperfections in the MODIS composite images (typically caused by inaccurate cloud masking, persistent cloud in a given region, and/or a highly dynamic fast-ice edge), automation of the fast-ice extent retrieval process was not possible. Each image was thus classified manually. A study of errors/biases of this process revealed that most images were able to be classified with a 2-sigma accuracy of +/- ~3%. More details are provided in Fraser et al., (2010).<br/><br/>*Version 1.2 with extra QC around the Mawson coast and Lutzow-Holm Bay<br/><br/>The directory named "pngs" contains browsable maps of fast-ice extent, in the form of Portable Network Graphics (PNG) images. Each of the 159 consecutive images (20-day intervals from Day Of Year (DOY) 61-80, 2000 to DOY 341-366, 2008) contains a map of fast-ice extent along the East Antarctic coast, generated from MODIS and AMSR-E imagery. The colour scale is as follows:<br/><br/>Dark blue: Fast ice, as classified from a single 20-day MODIS composite image<br/>Red: Fast ice, as classified using the previous or next 20-day MODIS composite images<br/>Yellow: Fast ice, as classified using a single 20-day AMSR-E composite image<br/>White: Antarctic continent (including ice shelves), as defined using the Mosaic of Antarctica product.<br/>Light blue: Southern ocean/pack ice/icebergs<br/><br/><br/>These maps are also provided as unformatted binary fast ice images, in the directory named "imgs". These .img files are all flat binary images of dimension 4300 * 425 pixels. The data type is 8-bit byte. Within the .img files, the value for each pixel indicates its cover:<br/>0: Southern Ocean, pack ice or icebergs, corresponding to light blue in the PNG files.<br/>1: Antarctic continent (including ice shelves), as defined using the Mosaic of Antarctica product, corresponding to white in the PNG files.<br/>2: Fast ice, as classified from a single 20-day MODIS composite image, corresponding to dark blue in the PNG files<br/>3: Fast ice, as classified using a single 20-day AMSR-E composite image, corresponding to yellow in the PNG files<br/>4: Fast ice, as classified using the previous or next 20-day MODIS composite images, corresponding to red in the PNG files<br/><br/>To assist in georeferencing these data, files containing information on the latitude and longitude of each pixel are provided in the directory named "geo". These files are summarised as follows:<br/><br/>lats.img: File containing the latitude of the centre of each pixel. File format is unformatted 32-bit floating point, 4300 * 425 pixels.<br/>lons.img: File containing the longitude of the centre of each pixel. File format is unformatted 32-bit floating point, 4300 * 425 pixels.<br/><br/>The .gpd Grid Point Descriptor file used to build the projection is also included. It contains parameters which you can use for matching your projection.<br/><br/>To refer to the time series, climatology, or maps of average persistence, please reference this paper:<br/>Fraser, A. D., R. A. Massom, K. J. Michael, B. K. Galton-Fenzi, and J. L. Lieser, East Antarctic landfast sea ice distribution and variability, 2000-08, Journal of Climate 25, 4, pp. 1137-1156, 2012<br/><br/>In addition, please cite the following reference when describing the process of generating these maps:<br/>Fraser, A.

An Immigrant Defends America
No full textMany people in the United States feel hopeless about their future, arguing that capitalism, police brutality, and racism prevent them from reaching their goals. Some even suggest that the American Dream is a lie and that the game is rigged against African-Americans, in particular. Jason D. Hill challenges this skepticism. He argues that success is a personal choice and that the vast numbers of upwardly-mobile immigrants are all the proof one needs of boundless American potential. He also takes issue with Ta-Nehisi Coates and writers like him, claiming that their fame and wealth undermine their own charges of victimization.
Jason D. Hill is a Professor of Philosophy, member of the Honors Distinguished Faculty, and Director of Teaching Practicum at DePaul University. He is the author of four books, the most recent of which is the soon-to-be-released We Have Overcome: An Immigrant’s Letter to the American People, available for pre-order on Amazon.com

Identification of a new gene mutated in Fraser syndrome and mouse myelencephalic blebs
No full textFraser syndrome is a recessive, multisystem disorder presenting with cryptophthalmos, syndactyly and renal defects and associated with loss-of-function mutations of the extracellular matrix protein FRAS1. Fras1 mutant mice have a blebbed phenotype characterized by intrauterine epithelial fragility generating serous and, later, hemorrhagic blisters. The myelencephalic blebs (my) strain has a similar phenotype. We mapped my to Frem2, a gene related to Fras1 and Frem1, and showed that a Frem2 gene-trap mutation was allelic to my. Expression of Frem2 in adult kidneys correlated with cyst formation in my homozygotes, indicating that the gene is required for maintaining the differentiated state of renal epithelia. Two individuals with Fraser syndrome were homozygous with respect to the same missense mutation of FREM2, confirming genetic heterogeneity. This is the only missense mutation reported in any blebbing mutant or individual with Fraser syndrome, suggesting that calcium binding in the CALXβ-cadherin motif is important for normal functioning of FREM2

No full textChapter 4 of Library Technology Reports (53, no. 5), "3-D Printers for Libraries, 2017 Edition"Chapter 4 of Library Technology Reports (vol. 53, no. 5), “3-D Printers for Libraries, 2017 Edition,” lists and discusses the 3-D printer companies and products that author Jason Griffey thinks are most effective and efficient for library use as well as a few experimental models that might bear watching in the future. The criteria used for evaluation include popularity, ease of use, support, and the degree to which the company espouses library values of openness and information access. The attempt will be made to provide buying advice for libraries, taking into account the possible differences in use cases that libraries may have

Part of the Sustainable futures speaker series sponsored by the Schatz Energy Research Center and the Environment and Community Program. In the 21st century, on the verge of what some are calling the Anthropocene, is there any place that's still really, truly wild? And, if so, how can we hold onto wildness as a touchstone for our relationship with the rest of nature? In this lecture, Jason will share some thoughts from his 2015 book, 'Satellites in the High Country', and will explore the meaning of wilderness today
