Case Study: Mr. Gabriel Marshal Nylowa Yak

In the following case, a refugee and victim of torture, fled religious persecution in Sudan. He first arrived in Syria where he made a claim to asylum to the UNHCR. His claim was initially refused and he fled to Hong Kong. The High Commissioner ruled that Gabriel was an "irregular mover" and that his appeal could not be considered in Hong Kong. He was sent against his will, back to Syria, without any of the documentation that substantiated his claim. During the entire time that his case was being considered, it was closely followed by Amnesty International. Gabriel was ultimately successful in his appeal and was granted protection as a refugee. He was resettled in the United States, where he lives today.Dans le cas qui suit, un réfugié, victime de la torture, s'enfuit de la persécution au Soudan. Il arriva en tout premier lieu en Syrie, où il soumit une demande d'asile à la HCR. Sa demande fut rejeté de prime d'abord, et il s'enfuit vers Hong Kong. Le Haut Commissaire jugea que Gabriel était une « personne aux déplacements irréguliers » et que son appel ne pouvait être entendue à Hong Kong. Contre son gré, il fut renvoyé en Syrie, mais sans aucun des documents étayant sa demande. Amnesty International avait suivi de près son cas pendant tout le temps que dura l'examen de son appel. Gabriel eut finalement gain de cause et obtint la protection du statut de réfugié. Il a été réinstallé aux États Unis, où il vit aujourd'hui

Magnetic Response in the Underdoped Cuprates

We examine the dynamical magnetic response of the underdoped cuprates by employing a phenomenological theory of a doped resonant valence bond state where the Fermi surface is truncated into four pockets. This theory predicts a resonant spin response which with increasing energy (0 to 100meV) appears as an hourglass. The very low energy spin response is found at (pi,pi +- delta) and (pi +- delta,pi) and is determined by scattering from the pockets' frontside to the tips of opposite pockets where a van Hove singularity resides. At energies beyond 100 meV, strong scattering is seen from (pi,0) to (pi,pi). This theory thus provides a semi-quantitative description of the spin response seen in both INS and RIXS experiments at all relevant energy scales

Expression of Sindbis virus structural proteins via recombinant vaccinia virus: synthesis, processing, and incorporation into mature Sindbis virions

We have obtained a vaccinia virus recombinant which contains a complete cDNA copy of the 26S RNA of Sindbis virus within the thymidine kinase gene of the vaccinia virus genome. This recombinant constitutively transcribed the Sindbis sequences throughout the infectious cycle, reflecting the dual early-late vaccinia promoter used in this construction. The Sindbis-derived transcripts were translationally active, giving rise to both precursor and mature structural proteins of Sindbis virus, including the capsid protein (C), the precursor of glycoprotein E2 (PE2), and the two mature envelope glycoproteins (E1 and E2). These are the same products translated from the 26S mRNA during Sindbis infection, and thus these proteins were apparently cleaved, glycosylated, and transported in a manner analogous to that seen during authentic Sindbis infections. By using epitope-specific antibodies, it was possible to demonstrate that recombinant-derived proteins were incorporated into Sindbis virions during coinfections with monoclonal antibody-resistant Sindbis variants. These results suggest that all the information necessary to specify the proper biogenesis of Sindbis virus structural proteins resides within the 26S sequences and that vaccinia may provide an appropriate system for using DNA molecular genetic manipulations to unravel a variety of questions pertinent to RNA virus replication

Neomycin resistance as a dominant selectable marker for selection and isolation of vaccinia virus recombinants

The antibiotic G418 was shown to be an effective inhibitor of vaccinia virus replication when an appropriate concentration of it was added to cell monolayers 48 h before infection. Genetic engineering techniques were used in concert with DNA transfection protocols to construct vaccinia virus recombinants containing the neomycin resistance gene (neo) from transposon Tn5. These recombinants contained the neo gene linked in either the correct or incorrect orientation relative to the vaccinia virus 7.5-kilodalton gene promoter which is expressed constitutively throughout the course of infection. The vaccinia virus recombinant containing the chimeric neo gene in the proper orientation was able to grow and form plaques in the presence of G418, whereas both the wild-type and the recombinant virus with the neo gene in the opposite polarity were inhibited by more than 98%. The effect of G418 on virus growth may be mediated at least in part by selective inhibition of the synthesis of a subset of late viral proteins. These results are discussed with reference to using this system, the conferral of resistance to G418 with neo as a positive selectable marker, to facilitate constructing vaccinia virus recombinants which contain foreign genes of interest

Restrictions on Student Voting: An Unconstitutional Anachronism?

Using Michigan as a vehicle for analysis because it has a student voting process representative of many states, this note seeks to accomplish four purposes: (1) an examination of the case law often underlying the presumption against student registrability; (2) an analysis of recent constitutional developments in the due process and equal protection areas as they relate to the particular problems posed by the student voter; (3) a survey of the competing local and student interests in the student vote issue; and (4) a conclusion regarding the likelihood that thwarted student voters can follow the paths of other disfranchised groups such as black citizens who have successfully achieved the unqualified right to vote

Predicting trophic position in sharks of the north-west Atlantic Ocean using stable isotope analysis

The definitive version was published in Journal of the Marine Biological Association of the UK 83 (2003): 1347-1350, doi:10.1017/S0025315403008798.Trophic positions (TP) were estimated for the blue shark (Prionace glauca), shortfin mako (Isurus oxyrinchus), thresher shark (Alopias vulpinus), and basking shark (Cetorhinus maximus) using stable isotope ratios of carbon ([delta]13C) and nitrogen ([delta]15N). The basking shark had the lowest TP (3·1) and [delta]15N value (10·4‰), whereas the thresher shark had the highest values (4·5, 15·2‰). Mako sharks showed considerable variation in TP and isotopic values, possibly due to foraging from both inshore and offshore waters. Thresher sharks were significantly more enriched in [delta]15N than blue sharks and mako sharks, suggesting a different prey base. The [delta]13C values of thresher sharks and mako sharks varied significantly, but neither was significantly different from that of blue sharks. No statistical differences were found between our TP estimations and those derived from published stomach contents analyses, indicating that stable isotope data may be used to estimate the trophic status of sharks.This work was supported by National Marine Fisheries Service Grant NA16MF1323 to M.E.L

Improving Student Learning Through Use of an In-class Material Processing Design Project

At Marquette University, hybrid project-based learning has been implemented in an undergraduate mechanical engineering course on materials processing and forming using a team-based approach. The goals of the project are to 1) introduce more active and student-centered activities to improve student engagement and mastery of core concepts, 2) increase students\u27 confidence in their ability to apply what they learned in the course to solving real-world problems, 3) enable students to gain experience using engineering software as part of the learning process and in applications context. While use of process modeling software in materials processing and manufacturing courses is not entirely new, the project has students actively developing a model around a realistic process, rather than passive users running canned models and reviewing the output. This paper presents details of the project and discusses preliminary results regarding its impact on student learning and confidence related to application of the course concepts. Recommendations for improving and expanding this in-class project are presented, along with a description of the assessment methods used to measure the impact on students

Completely positive maps with memory

The prevailing description for dissipative quantum dynamics is given by the Lindblad form of a Markovian master equation, used under the assumption that memory effects are negligible. However, in certain physical situations, the master equation is essentially of a non-Markovian nature. This paper examines master equations that possess a memory kernel, leading to a replacement of white noise by colored noise. The conditions under which this leads to a completely positive, trace-preserving map are discussed for an exponential memory kernel. A physical model that possesses such an exponential memory kernel is presented. This model contains a classical, fluctuating environment based on random telegraph signal stochastic variables.Comment: 4 page
