Interference effects in nonplanar wires with a two-dimensional electron gas

We have studied the universal conductance fluctuations (UCF) due to quantum interface in a two-dimensional electron gas (2DEG) grown on the substrates with pre-patterned, sub-micron wires. The dependence of UCF on the angle between the direction of the magnetic field and the substrate has been investigated. We found, that magnetoresistance traces for different angles are completely uncorrelated. A non-planar character of electron motion is responsible for these angular conductance fluctuations. We compared the experimental results with a simple geometrical model.

Mary E. Frayser Papers - Accession 1

The Mary E. Frayser Papers consists of correspondence, speeches, reports, clippings, minutes, histories, family histories, constitutions and bylaws, membership lists, program notes, photographs, and other papers, relating to her work with the South Carolina Extension Service (1912-1940) Winthrop College, her involvement with the South Carolina Council for the Common Good (1935-1952), the South Carolina Federation of Women’s Clubs (1926-1952), the South Carolina Status of Women Conference (1945-1952), the South Carolina Division of the American Association of University Women (AAUW) (1929, 1935-1949), the South Carolina Interracial Institute (1938-1942), the South Carolina Division of the Southern Regional Council (1944-1951), and the South Carolina Conference of Social Work (1936-1967). There are also papers relating to Frayser’s efforts to promote social and economic legislation and participation by women in public affairs and her interest in libraries and work in the movement for the support of public libraries in South Carolina (1925-1968). Correspondents included G.H. Aault, Evan Chesterman, Wil Lou Gray, Sarah Hughes, Christine South Gee, and Maude Massey Rogers. This collection is a good source of women’s club activities in the twentieth century. Important areas of research would include the way club activity affected social and economic legislation in the state and the various forces involved in the movement for state tax supported libraries. While the papers do range from 1841 to 1953, the greater bulk of the papers extend from the early 1930s to about 1947. Since the work of the various women's club organizations were so inter-related, a researcher working with the papers of a particular organization for a particular time span should consider the Frayser papers of all other organizations. The related papers for the “Correspondence and Related Papers” series for particular organizations are generally similar and include: memoranda, outlines, reports, resolutions, minutes, etc. Additional Frayser information can be found by referring to the Winthrop University Archives (official records).

Implementazione automatica di protocolli di interazione AUML mediante reti di Petri

Questa tesi si basa su una serie di lavori precedenti, volti ad analizzare la correlazione tra i modelli AUML e le reti di Petri, per riuscire a fornire una metodologia di traduzione dai primi alle seconde. Questa traduzione permetterà di applicare tecniche di model checking alle reti così create, al fine di stabilire le proprietà necessarie al sistema per poter essere realizzato effettivamente. Verrà poi discussa un'implementazione di tale algoritmo sviluppata in tuProlog ed un primo approccio al model checking utilizzando il programma Maude. Con piccole modifiche all'algoritmo utilizzato per la conversione dei diagrammi AUML in reti di Petri, è stato possibile, inoltre, realizzare un sistema di implementazione automatica dei protocolli precedentemente analizzati, verso due piattaforme per la realizzazione di sistemi multiagente: Jason e TuCSoN. Verranno quindi presentate tre implementazioni diverse: la prima per la piattaforma Jason, che utilizza degli agenti BDI per realizzare il protocollo di interazione; la seconda per la piattaforma TuCSoN, che utilizza il modello A&A per rendersi compatibile ad un ambiente distribuito, ma che ricalca la struttura dell'implementazione precedente; la terza ancora per TuCSoN, che sfrutta gli strumenti forniti dalle reazioni ReSpecT per generare degli artefatti in grado di fornire una infrastruttura in grado di garantire la realizzazione del protocollo di interazione agli agenti partecipanti. Infine, verranno discusse le caratteristiche di queste tre differenti implementazioni su un caso di studio reale, analizzandone i punti chiave.

Impact of sepsis on neurodevelopmental outcome in a Swiss National Cohort of extremely premature infants

Neonatal sepsis causes high mortality and morbidity in preterm infants, but less is known regarding the long-term outcome after sepsis. This study aimed to determine the impact of sepsis on neurodevelopment at 2 years' corrected age in extremely preterm infants.

Outcome at two years of age in a Swiss national cohort of extremely preterm infants born between 2000 and 2008

Background While survival rates of extremely preterm infants have improved over the last decades, the incidence of neurodevelopmental disability (ND) in survivors remains high. Representative current data on the severity of disability and of risk factors associated with poor outcome in this growing population are necessary for clinical guidance and parent counselling. Methods Prospective longitudinal multicentre cohort study of preterm infants born in Switzerland between 240/7 and 276/7 weeks gestational age during 2000–2008. Mortality, adverse outcome (death or severe ND) at two years, and predictors for poor outcome were analysed using multilevel multivariate logistic regression. Neurodevelopment was assessed using Bayley Scales of Infant Development II. Cerebral palsy was graded after the Gross Motor Function Classification System. Results Of 1266 live born infants, 422 (33%) died. Follow-up information was available for 684 (81%) survivors: 440 (64%) showed favourable outcome, 166 (24%) moderate ND, and 78 (11%) severe ND. At birth, lower gestational age, intrauterine growth restriction and absence of antenatal corticosteroids were associated with mortality and adverse outcome (p < 0.001). At 360/7 weeks postmenstrual age, bronchopulmonary dysplasia, major brain injury and retinopathy of prematurity were the main predictors for adverse outcome (p < 0.05). Survival without moderate or severe ND increased from 27% to 39% during the observation period (p = 0.02). Conclusions In this recent Swiss national cohort study of extremely preterm infants, neonatal mortality was determined by gestational age, birth weight, and antenatal corticosteroids while neurodevelopmental outcome was determined by the major neonatal morbidities. We observed an increase of survival without moderate or severe disability.

Intercomparison of stratospheric ozone profiles for the assessment of the upgraded GROMOS radiometer at Bern

Since November 1994, the GROund-based Millimeter-wave Ozone Spectrometer (GROMOS) measures stratospheric and lower mesospheric ozone in Bern, Switzerland (47.95° N, 7.44° E). GROMOS is part of the Network for the Detection of Atmospheric Composition Change (NDACC). In July 2009, a Fast-Fourier-Transform spectrometer (FFTS) has been added as backend to GROMOS. The new FFTS and the original filter bench (FB) measured parallel for over two years. In October 2011, the FB has been turned off and the FFTS is now used to continue the ozone time series. For a consolidated ozone time series in the frame of NDACC, the quality of the stratospheric ozone profiles obtained with the FFTS has to be assessed. The FFTS results from July 2009 to December 2011 are compared to ozone profiles retrieved by the FB. FFTS and FB of the GROMOS microwave radiometer agree within 5% above 20 hPa. A later harmonization of both time series will be realized by taking the FFTS as benchmark for the FB. Ozone profiles from the FFTS are also compared to coinciding lidar measurements from the Observatoire Haute Provence (OHP), France. For the time period studied a maximum mean difference (lidar – GROMOS FFTS) of +3.8% at 3.1 hPa and a minimum mean difference of +1.4% at 8 hPa is found. Further, intercomparisons with ozone profiles from other independent instruments are performed: satellite measurements include MIPAS onboard ENVISAT, SABER onboard TIMED, MLS onboard EOS Aura and ACE-FTS onboard SCISAT-1. Additionally, ozonesondes launched from Payerne, Switzerland, are used in the lower stratosphere. Mean relative differences of GROMOS FFTS and these independent instruments are less than 10% between 50 and 0.1 hPa.

Hole in the Head: a Play, Accompanied by a Conspectus of Knowledge, Both Repressed and Researched, that Directly Influenced the Playwright in Her Development of a New Work

"Hole in the Head" is a play about a woman who wakes up. Maude wakes up in the first act, and in every subsequent scene she undergoes some form of physical or emotional awakening as characters walk in and out of her front door."Hole in the Head" is accompanied by an introduction that attempts to understand the interplay between creativity and academia through an analysis of theatre, feminist and queer theory, and science.

Female pipefish can detect the immune status of their mates

Given the ubiquity of the parasites and their important fitness consequences on mate and offspring condition, selection for the ability to distinguish healthy from parasitized potential mates is a key process to enhance Darwinian fitness. In this study, we experimentally evaluated how the immunological experience of two potential partners influences mate choice, using the sex-role-reversed pipefish Syngnathus typhle. We exposed S. typhle to immune challenges with heat-killed Vibrio bacteria and investigated whether the activation of the immune system determined mate preferences. Our results demonstrate that the immune status of the potential partners influenced female mate preference, such that females that were exposed to an immune challenge became choosy and favored unchallenged males. Males, however, did not show any preferences for female immune status. In this context, we discuss mate choice decisions and behavioral plasticity as a complex result of immune challenge, severity of infection, as well as trans-generational effects.
