The CaNOP CubeSat Mission

The CaNOP Cubesat Mission is a student based cubesat mission based out of Carthage College. The purpose of the mission is to test a method for multispectral imaging, image changes in the rain forest on Earth, and visualize changes in urban night lighting due to the growth in low power LED street lights. The 3U Cubesat camera system is designed to replicate early Landsat remote sensing capabilities. For this mission CaNOP is using a commercial four-band multispectral push-broom imager designed for precision agriculture applications. This imaging system reproduces a subset of the visible and near-IR Landsat and MODIS spectral imaging channels at a ground pixel size of 60m at an orbital altitude of 400 km. CaNOP will be deployed from the ISS in Fall 2019. Communications will be through our LinkStar-STX3 and LinkStar duplex radios which link the satellite through the Globalstar network providing global beaconing and positioning, command and control, and image download. We will be able to control swaths to image based on known location via our web ground interface. For this presentation we will discuss the mission plan and mission science, provide comparison figures of merit for CaNOP, present the new PC104 based BeagleBone Black interface and architecture and how it was integrated with the cubesat, and how data from the mission will be collected and shared with the community

Effect of Abundance and Survey Protocol on Estimates of Occupancy and Detection Probability for Northern Bobwhites

We compared estimates of occupancy of northern bobwhite (Colinus virginianus) between areas with relatively low and high abundance using single-survey and multiple-survey protocols, with and without accounting for detection probability, and investigated how time during the breeding season affected detection probability in Oklahoma, USA, in 2009–2011. Estimates of occupancy and detection probability increased as the number of survey occasions increased. Detection probability was significantly higher in the area of high abundance (P 0.001), and increased as the breeding season advanced from mid-May to late July. Accounting for detection probability increased occupancy estimates by 31% in the low-abundance area but only 1.9% in the high abundance area when using 3 survey occasions per year. Managers using occupancy to detect changes in bobwhite populations should use 4 survey occasions per year to ensure accurate estimates of both occupancy and detection probability

Eye movements in code reading:relaxing the linear order

Abstract—Code reading is an important skill in programming. Inspired by the linearity that people exhibit while natural lan-guage text reading, we designed local and global gaze-based mea-sures to characterize linearity (left-to-right and top-to-bottom) in reading source code. Unlike natural language text, source code is executable and requires a specific reading approach. To validate these measures, we compared the eye movements of novice and expert programmers who were asked to read and comprehend short snippets of natural language text and Java programs. Our results show that novices read source code less linearly than natural language text. Moreover, experts read code less linearly than novices. These findings indicate that there are specific differences between reading natural language and source code, and suggest that non-linear reading skills increase with expertise. We discuss the implications for practitioners and educators. I

Paperless Transfer of Medical Images: Storing Patient Data in Medical Images

Medical images have become an integral part ofpatient diagnosis in recent years. With the introduction of HealthInformation Management Systems (HIMS) used for the storageand sharing of patient data, as well as the use of the PictureArchiving and Communication Systems (PACS) formanipulating and storage of CT Scans, X-rays, MRIs and othermedical images, the security of patient data has become a seriousconcern for medical professionals. The secure transfer of theseimages along with patient data is necessary for maintainingconfidentiality as required by the Data Protection Act, 2011 inTrinidad and Tobago and similar legislation worldwide. Tofacilitate this secure transfer, different digital watermarking andsteganography techniques have been proposed to safely hideinformation in these digital images. This paper focuses on theamount of data that can be embedded into typical medical imageswithout compromising visual quality. In addition, ExploitingModification Direction (EMD) is selected as the method of choicefor hiding information in medical images and it is compared tothe commonly used Least Significant Bit (LSB) method.Preliminary results show that by using EMD there little to nodistortion even at the highest embedding capacity

Three experimental homes for the elderly mentally ill : final report

Against a background of increasing numbers of elderly mentally ill people, the Department of Health [Liverpool] established an initiative to develop and evaluate alternative ways of caring for this client group. Three experimental schemes were established, with the Department providing 50% funding for five years. All three units aim to provide a homely and domestic living environment and provide individualised care for clients.Chapter 1. INTRODUCTION; Chapter 2. METHODOLOGY; Chapter 3.

Northern Bobwhite and Bird Community Response to Habitat Restoration in Oklahoma

Reversing the population decline of Northern Bobwhites (Colinus virginianus, hereafter bobwhite), an economically important gamebird, in Oklahoma, is a priority for wildlife managers in the state. The Quail Habitat Restoration Initiative (QHRI) was initiated in 2008 to address this issue by doing cost-share with private landowners for the restoration of bobwhite habitat. The purpose of my study was to evaluate the effect of this program on bobwhites and other grassland bird species of conservation concern, and evaluate the key factors affecting the outcome of the program. There was very little bobwhite response to restoration treatments, and occupancy of restoration areas did not significantly increase. The main habitat factor effecting bobwhite occupancy on a sample unit was overstory canopy cover, with a secondary effect of visual obstruction. Bobwhite occupancy was also significantly affected by the amount of habitat within 1 km of the sample unit. Most restoration areas were within the appropriate landscape context for bobwhites to recolonize the site, but proper local habitat condition were only created within a few sample units and this was the limiting factor in the success of the QHRI program. Community analysis showed that bird community composition responded most strongly to overstory canopy cover and visual obstruction, and many declining grassland bird species were strongly associated with bobwhites in species groupings from cluster analysis. Bobwhites show the potential to act as an umbrella species for declining bird species that rely on early-successional habitat. Occupancy modeling showed that estimates of bobwhite occupancy may be biased low by as much as 30% if detection probability is not accounted for, especially in areas where they are uncommon. Maximizing detection probability in the study design, and accounting for it in the analysis, must be done if estimates of bobwhite occupancy are to be accurate.Department of Natural Resource Ecology and Managemen

Dominant mutations of the Notch ligand Jagged1 cause peripheral neuropathy

Notch signaling is a highly conserved intercellular pathway with tightly regulated and pleiotropic roles in normal tissue development and homeostasis. Dysregulated Notch signaling has also been implicated in human disease, including multiple forms of cancer, and represents an emerging therapeutic target. Successful development of such therapeutics requires a detailed understanding of potential on-target toxicities. Here, we identify autosomal dominant mutations of the canonical Notch ligand Jagged1 (or JAG1) as a cause of peripheral nerve disease in 2 unrelated families with the hereditary axonal neuropathy Charcot-Marie-Tooth disease type 2 (CMT2). Affected individuals in both families exhibited severe vocal fold paresis, a rare feature of peripheral nerve disease that can be life-threatening. Our studies of mutant protein posttranslational modification and localization indicated that the mutations (p.Ser577Arg, p.Ser650Pro) impair protein glycosylation and reduce JAG1 cell surface expression. Mice harboring heterozygous CMT2-associated mutations exhibited mild peripheral neuropathy, and homozygous expression resulted in embryonic lethality by midgestation. Together, our findings highlight a critical role for JAG1 in maintaining peripheral nerve integrity, particularly in the recurrent laryngeal nerve, and provide a basis for the evaluation of peripheral neuropathy as part of the clinical development of Notch pathway-modulating therapeutics.This article is freely available via Open Access.

La fabrique des indésirables

Basé sur une recherche ethnographique réalisée dans un aéroport européen, cet article analyse les pratiques de contrôle des gardes-frontières auprès des voyageurs ressortissants de pays tiers, proposant une anthropologie du pouvoir des contrôles aux frontières qui examine l’usage de la violence symbolique et du pouvoir étatique discrétionnaire. En nous appuyant sur les théories des « street-level bureaucracies » et celles des interactions sociales, nous analysons les pratiques de travail, les routines professionnelles et l’organisation du travail des gardes-frontières en démontrant que ce sont ces dernières qui activent et constituent la frontière et la politique du contrôle de la mobilité. Nous soutenons que le contrôle au sein de l’aéroport est basé à la fois sur l’influence de la frontière-réseau, ainsi que sur une performance dramaturgique de gestion bureaucratique qui créent les voyageurs légitimes et les passagers indésirables, évitent de potentielles protestations de ces derniers et feignent une responsabilité (accountability), destinée à un public plus large de citoyens. En tant que tel, le contrôle de la frontière serait dès lors plus un acte politique symbolique qu’un outil efficace de politique de mobilité et d’immigration.Based on empirical research in a European airport, this article analyses how border guards control third-country nationals by advancing an anthropology of the power of border control as exhibited by the use of symbolic violence and discretionary state power. Leaning on the theories of street-level bureaucracies and organizations, we analyze the work practices, professional routines and organization of the work of border guards in order to show how border guards activate and constitute the border and the control of mobility. We argue that control at the airport is based both on the influence of the network-border and on a dramaturgical performance of bureaucratic governance, which is meant to create legitimate travelers and undesirable passengers, while circumventing potential protests of the latter and simulating accountability toward the broader public of citizens. As such, border control is more of a symbolic act than an efficient tool of immigration policy
