description: We present the results from a spectroscopic study of 1080 nearby active M dwarfs, selected by correlating the 2MASS and ROSAT catalogs. We have derived the spectral types and estimated distances for all of our stars. The spectral types range between K5 and M6. Nearly half of our stars lie within 50 pc. We have measured the equivalent width of the H alpha emission line. Our targets show an increase in chromospheric activity from early to mid-spectral types, with a peak in activity around M5. Using the count rate and hardness ratios obtained from the ROSAT catalog, we have derived the X-ray luminosities. Our stars display a "saturation-type" relation between the chromospheric and coronal activity. The relation is such that log (Lx/Lbol) remains "saturated" at a value of about -3 for varying H alpha equivalent width. We have found 568 matches in the USNO-B catalog, and have derived the tangential velocities for these stars. There is a slight trend of decreasing chromospheric activity with age, such that the stars with higher Vtan have lower H alpha equivalent widths. The coronal emission, however, remains saturated at a value of log (Lx/Lbol) -3 for varying tangential velocities, suggesting that the coronal activity remains saturated with age. We do not find any break in the saturation-type relation at the spectral type where stars become fully convective (~M3.5). Most of the stars in our sample show more coronal emission than the dMe stars in the Hyades and Praesepe clusters, and have Vtan< 40km/s, suggesting a young population.

description: We report the efficient and fast ($\sim 2\mathrm{Hz}$) preparation of randomly loaded 1D chains of individual $^{87}$Rb atoms and of dense atomic clouds trapped in optical tweezers using a new experimental platform. This platform is designed for the study of both structured and disordered atomic systems in free space. It is composed of two high-resolution optical systems perpendicular to each other, enhancing observation and manipulation capabilities. The setup includes a dynamically controllable telescope, which we use to vary the tweezer beam waist. A D1 $Λ$-enhanced gray molasses enhances the loading of the traps from a magneto-optical trap. Using these tools, we prepare chains of up to $\sim 100$ atoms separated by $\sim 1 \mathrm{μm}$ by retro-reflecting the tweezer light, hence producing a 1D optical lattice with strong transverse confinement. Dense atomic clouds with peak densities up to $n_0 = 10^{15}\:\mathrm{at}/\mathrm{cm}^3$ are obtained by compression of an initial cloud. This high density results into interatomic distances smaller than $λ/(2π)$ for the D2 optical transitions, making it ideal to study light-induced interactions in dense samples.

description: We consider some aspects of classical S-duality transformations in first order actions taken into account the general covariance of the Dirac algorithm and the transformation properties of the Dirac bracket. By classical S-Duality transformations we mean a field redefinition that interchanges the equations of motion and its associated Bianchi identities. By working from a first order variational principle and performing the corresponding Dirac analysis we find that the standard electro-magnetic duality can be reformulated as a canonical local transformation. The reduction from this phase space to the original phase space variables coincides with the well known result about duality as a canonical non local transformation. We have also applied our ideas to the bosonic string. These Dualities are not canonical transformations for the Dirac bracket and relate actions with different kinetic terms in the reduced space.

description: В статье приведены материалы, посвященные решению проблемы обогащения незаменимыми нутриентами традиционных продуктов на фоне общей тенденции к уменьшению их энергетической ценности. Выявлены основные направления развития отечественной и мировой пищевой индустрии. Обоснована необходимость повышения технологической адекватности кисломолочных продуктов. С этой целью разработана технология производства кисломолочного соуса, включающая рациональную переработку вторичного молочного сырья, использование в качестве наполнителей горчичного порошка, свежих трав, чеснока, а также комплексное применение животного и растительного белков. В ходе исследований посредством метода дегустационной оценки выявлена пищевая система, в которой набухание изолята происходит максимально, то есть оптимальными условиями для данной стадии являются выбор в качестве дисперсионной среды воды, массовое соотношение соевого изолята и воды 1:5. Для подбора наиболее рациональных параметров ультрафиолетового облучения наполнителей исследована динамика образования дрожжей и плесневых грибов в суспензиях ароматных трав в процессе хранения. В результате проведения эксперимента рост дрожжей в чашках Петри не обнаружен, а подсчет мицелий плесневых грибов показал, что при хранении в течение пяти суток их количество составляет 104. Для анализа эффективности использования стабилизаторов исследованы изменения структурно-механических свойств соусов в зависимости от количества и вида вносимых загустителей. Посредством метода капиллярной вискозиметрии определены значения показателей условной вязкости образцов. Экспериментальные данные вязкости свидетельствуют о рациональности использования желатина в качестве структурообразователя в рецептурах соусов кисломолочных, а также о возможности использования крахмала как альтернативного стабилизатора. При исследовании динамики нарастания титруемой кислотности образцов в течение семи дней выявлено, что благодаря бактерицидным свойствам горчицы и чеснока происходит замедление нарастания кислотности соусов в процессе хранения, а внесение в рецептуру свежих трав, обработанных УФ-излучением, не снижает сроков годности готового продукта.

description: Computersysteme, die wir alltäglich verwenden und von denen wir gewissermaßen von abhängen, sind nicht frei von Fehlern. Diese können hardware- oder softwareseitig ursächlich sein und als Konsequenz Einfluss auf die Programme und Daten haben, die wir auf den Systemen verwenden. Gründe für Fehler sind steigende Designkomplexität, kleinere Fertigungsbreiten von Hardware oder komplexer werdende Softwaremodule. Darüber hinaus können auch bewusst eingebrachte Hintertüren dafür sorgen, dass ein System sich anders verhält als erwartet. Letztendlich bleibt nur übrig den Herstellern zu vertrauen, dass ihre Soft- und Hardwareprodukte wie versprochen funktionieren und frei von Fehlern und Hintertüren sind. Diese Arbeit stellt einen Ansatz vor, um die Korrektheit einer Anwendungsausführung zu überprüfen, ohne darauf angewiesen zu sein den Herstellern zu vertrauen. Der Ansatz namens Securing Process Execution by Recording and Replaying the Inner Process State (SPERRIPS) verifiziert die Korrektheit einer Anwendungsausführung über zwei Systeme hinweg auf dem Abstraktionslevel von Systemaufrufen (engl. system calls). Dazu wird die zu verifizierende Anwendung auf zwei unterschiedlichen Systemen ausgeführt und auftretende Unterschiede in den Programmausführungen inspiziert. Eine Ausführung gilt als korrekt und verifiziert, wenn sie auf beiden Systemen gleich stattfindet, indem höchstens akzeptierbare Unterschiede auftreten. Falls unakzeptierbare Unterschiede auftreten, wird die Programmausführung abgebrochen. Unter Berücksichtigung von unter anderem unterschiedlichen Systemumgebungen, Addressraumverwürfelung und verschachtelten Datenstrukturen werden in dieser Arbeit akzeptierbare und unakzeptierbare Unterschiede am Beispiel der Systemaufrufe der cat Anwendung definiert. Etwaige unakzeptierbare Unterschiede deuten auf Fehlverhalten einer der beiden Systeme hin, welches in den Komponenten unterhalb des betrachteten Abstraktionslevel von Systemaufrufen begründet ist. Dies betrifft entweder Hardwarekomponenten oder interne Abläufe im Betriebssystemkern. Diese Arbeit liefert eine Konzeption und eine Implementierung für SPERRIPS. Die Implementierung wurde anhand der vier Anwendungen echo, hostname, cat und ping evaluiert. Dies demonstriert die Fähigkeit des Ansatzes und der Implementierung die Korrektheit von Anwendungen zu überprüfen bzw. Abweichungen in ihren Ausführungen festzustellen. In einen Linuxkern bewusst eingebautes Fehlverhalten, das zur Laufzeit zu Abweichungen in den Programmausführungen führte, wurde erfolgreich detektiert.

description: In the pre-reionization Universe, the regions of the inter-galactic medium (IGM) which are far from luminous sources are the last to undergo reionization. Until then, they should be scarcely affected by stellar radiation; instead, the X-ray emission from an early black hole (BH) population can have much larger influence. We investigate the effects of such emission, looking at a number of BH model populations (differing for the cosmological density evolution of BHs, the BH properties, and the spectral energy distribution of the BH emission). We find that BH radiation can easily heat the IGM to 10^3-10^4 K, while achieving partial ionization. The most interesting consequence of this heating is that BHs are expected to induce a 21-cm signal (delta T_b ~ 20-30 mK at z

description: Tellurite glasses, which contain Tellurium dioxide as the main component, have some remarkable optical properties which are well recognised and exploited in the bulk optics and fibre fields. They include a high acousto-optic figure of merit, wide mid infrared transparency, the highest optical nonlinearity amongst oxides, and excellent rare earth hosting, etc. Despite these attractive properties, until now, no one has succeeded in fabricating low loss planar waveguides in these materials. This work develops high quality optical planar waveguides in Tellurium dioxide for the first time. The project investigates the materials science for optical Tellurium dioxide films and discovers an appropriate waveguide fabrication method. The thin films have been fabricated by reactive radio frequency magnetron sputtering using a Tellurium target in an oxygen and argon atmosphere. Propagation losses at 1550nm in the planar films are 0.1dB/cm or lower in stoichiometric composition. The properties of films have been also found to be stable with thermal annealing up to 300 degree Celsius. Plasma etching of tellurite glasses has been systematically studied. High quality etching of Tellurium dioxide and chalcogenide glass films has been demonstrated with a Methane/Hydrogen/Argon gas mixture. As a result, a fabrication recipe which produces low loss (0.1dB/cm) planar waveguides has been discovered. The nonlinear coefficient of the sputtered TeO2 has been characterised by self-phase modulation (SPM) experiments and the second order nonlinear coefficient has been measured to be around 25 times that of silica. Significant signal conversion, -4dB, has achieved with large bandwidth of 30nm in the four-wave mixing (FWM) experiment pumped at 1550nm in a slightly normal dispersion waveguide. Erbium doped Tellurium oxide thin films have also been fabricated by co-sputtering of Erbium and Tellurium targets into an Oxygen and Argon atmosphere. The obtained films have been found to have good properties for Erbium doped waveguide amplifiers. The Erbium concentration can be controlled within the range of interest with Erbium/Tellurium ratios ranging from 0.1% to 3% or more. The 1.5 micrometre photoluminescence properties of the films are excellent with effective bandwidth of more that 60nm and intrinsic lifetime of order of 3ms. Despite the fact that there was OH contamination in the films, single mode Erbium doped waveguide amplifiers with high internal gain have been successfully obtained. The 1480nm pumped amplifier achieved internal gain from below 1520nm to beyond 1600nm. The peak gain of 2.8dB/cm and 40nm 3dB gain bandwidth have been accomplished. These results are a major stepping stone towards ""system-on-chip"" optical applications for telecom and mid infrared optics given the multifunctional nature of tellurite materials. -- provided by Candidate.

description: We construct a first order parent field theory for free higher spin gauge fields on constant curvature spaces. As in the previously considered flat case, both Fronsdal's and Vasiliev's unfolded formulations can be reached by two different straightforward reductions. The parent theory itself is formulated using a higher dimensional embedding space and turns out to be geometrically extremely transparent and free of the intricacies of both of its reductions.

description: A search for excited neutrinos is performed using the full $e^{-}p$ data sample collected by the H1 experiment at HERA at a centre-of-mass energy of 319 GeV, corresponding to a total luminosity of 184 pb$^{-1}$.The electroweak decays of excited neutrinos $ν^{*}{\to}νγ$, $ν^{*}{\to}νZ$ and $ν^{*}{\to}eW$ with subsequent hadronic or leptonic decays of the $W$ and $Z$ bosons are considered. No evidence for excited neutrino production is found. Mass dependent exclusion limits on $ν^*$ production cross sections and on the ratio of the coupling to the compositeness scale $f/Λ$ are derived within gauge mediated models. A limit on $f/Λ$, independent of the relative couplings to the SU(2) and U(1) gauge bosons, is also determined. These limits extend the excluded region to higher masses than has been possible in previous excited neutrino searches.

How and When Implicit Attitudes About Smoking Affect  Decision Making in the Personal Process of Smoking Cessation

description: Recent theories of attitudes and cognition have made a distinction between explicit attitudes that are conscious, deliberate judgments people make when asked to do so, and implicit attitudes, or those that are made automatically and without conscious effort (Greenwald and Banaji, 1995). This study integrated research and theory of implicit attitudes about smoking with the Transtheoretical Model's understanding of the process individuals go through as they quit smoking, to test the moderating effect of motivation to change on implicit smoking attitudes and to evaluate the indirect (mediated) effects of implicit smoking attitudes on cigarette demand through explicit smoking attitudes. Participants were N=283 daily smokers who completed an online survey that measured characteristics of their smoking, motivational Readiness to change, decisional balance considerations (Pros and Cons of smoking), and demand for cigarettes (Cigarette Purchase Task), before completing the Smoking Implicit Association Test. Results of multiple regression analyses indicated that as implicit attitudes about smoking became more positive, smokers reported on average more explicit positive attitudes (Pros of smoking) about smoking and less negative explicit attitudes (Cons of smoking) about smoking, beyond the effect Readiness for change had on those explicit smoking attitudes. Readiness to change did not moderate the effect of implicit smoking attitudes on decisional balance considerations. Decisional balance considerations were important predictors of smoker's responses on the smoking purchase task and accounted for the relationship between implicit smoking attitudes and choices on a hypothetical smoking purchase task. More positive implicit smoking attitudes indirectly predicted that smokers would purchase cigarettes at higher average prices before consumption dropped to zero, greater average maximum financial expenditure on cigarettes, and higher average price at which expenditure was maximized. These results may be useful for understanding how cigarette prices affect attitudes about smoking and increase the likelihood that people will quit.
Writing the Resistance: A Palestinian Intellectual History, 1967-1974
Creators: name: Quenzer, Katlyn
Publisher: name: The Australian National University
Year: 2019

description: This thesis explores the ideological work of the intellectuals involved in the Palestinian Resistance, and the Palestinian Liberation Organization more specifically, from 1967 to 1974. In particular, it sets out to answer the following question: What were the changing roles of the intellectuals involved in the Palestinian Liberation Organization (PLO) from 1967 to 1974, particularly in relation to anti-colonial politics, and why did they change? Being a particularly fertile time in Palestinian resistance history, many of those involved in the movement had the opportunity to explore new ideological possibilities for resistance and worked to link their movement ideologically to revolutionary resistance movements taking place globally at that time. The 1967 defeat was particularly poignant for Palestinian and Arab intellectuals, as it demonstrated to them that the work of the Ba'thists and Arab nationalists during the 1950s and 1960s had not created the necessary changes to liberate Palestine and, in their opinions, to liberate the entire society. Such changes, the intellectuals had hoped, would bring forth a larger revolution for the Arab world. With criticisms of local regimes, the intervention of external governments, and Zionism itself, they worked to reshape Palestinian resistance and reimagine Arab liberation. Yet due to fractured relationships and general disunity, it became difficult to create the type of resistance they had imagined. Three factors have seemed constraining: the shortcomings of the intellectuals, external factors, and problems in the ideas they developed for their society. Along with presenting the research question and hypothesis and defining key terms, the Introduction provides a literature review. The rest of the thesis chapters are arranged thematically and chronologically. Chapter One provides historical links between this newer generation of intellectuals and the older generation at the end of the Ottoman Empire and the beginning of the Mandate period. In Chapter Two, the initial reactions to the 1967 Defeat and the unique opportunity the PLO and its leaders had following it are analysed. Chapter Three considers the factionalism that took place within the PLO and the various ideological streams that were born of this. Chapter Four explicates the particular reasons why the ideologies they developed were troubled from the start, as well as some of the fundamental ironies within them. In addition to the possibility that their ideas did not suit the needs of the population in part because they did not have mass support, Chapter Five raises the notion that the efforts of the PLO's intellectuals may have been overly quixotic, as some have argued. The Conclusion suggests that, in many ways, the period ends as it begins, with their dreams of revolution as dreams and their criticisms of the society and each other as they were after soon after the Defeat.

description: Chinese floating population children are at risk for being the target of teasing and bullying, and for experiencing loneliness, lower self-esteem, and lack of opportunity to develop social skills. The overall goal of the dissertation project was to examine the factors that may contribute to Chinese floating population children's social and emotional development. First, the roles of determinants of parenting (maternal psychological well-being, acculturation to the urban culture, and social support), parenting styles (authoritarian parenting and authoritative parenting), and indigenous parenting practices (shaming/love withdrawal and maternal involvement) on Chinese floating population children's anxious shyness, regulated shyness and internalizing problems were explored. Further, the complex relations between parenting styles, child effortful control, and three child shyness subtypes (temperamental shyness, anxious shyness, and regulated shyness) were examined in moderated mediation models.   Four hundred and eighty Chinese floating population mothers with preschool children residing in three cities in Guangdong Province, China participated in the study. The results showed that floating population mothers' acculturation to the urban culture was associated with greater maternal endorsement of the authoritative parenting style and less engagement in the authoritarian parenting style. Also, maternal authoritarian parenting style mediated the relation between mothers' acculturation to the urban culture and children's display of regulated shyness. Moreover, the results from the moderated mediation models indicated that floating population mothers' authoritarian parenting style was negatively associated with their children's effortful control. Child effortful control was in turn positively related to children's regulated shyness, but only for children with low levels of temperamental shyness.  The results from the dissertation project contributed to the current literature on children's social withdrawal by identifying predictors of parenting, and parenting and child contributions to shyness in a unique but rapidly growing sample of floating population children. These findings have important implications for the promotion of healthy social-emotional development among floating population children in China.

description: Information retrieval is the area of study concerned with the process of searching, recovering and interpreting information from large amounts of data. In this Thesis we show that many of the problems in information retrieval consist of structured learning, where the goal is to learn predictors of complex output structures, consisting of many inter-dependent variables. We then attack these problems using principled machine learning methods that are specifically suited for such scenarios. In the process of doing so, we develop new models, new model extensions and new algorithms that, when integrated with existing methodology, comprise a new set of tools for solving a variety of information retrieval problems. Firstly, we cover the multi-label classification problem, where we seek to predict a set of labels associated with a given object; the output in this case is structured, as the output variables are interdependent. Secondly, we focus on document ranking, where given a query and a set of documents associated with it we want to rank them according to their relevance with respect to the query; here, again, we have a structured output - a ranking of documents. Thirdly, we address topic models, where we are given a set of documents and attempt to find a compact representation of them, by learning latent topics and associating a topic distribution to each document; the output is again structured, consisting of word and topic distributions. For all the above problems, we obtain state-of-the-art solutions as attested by empirical performance in publicly available real-world datasets.

description: Community Health Workers (CHWs) are an integral part of health-care in underserved or un-served areas. They act as liaisons between health-care providers and patients in communities. They collect information about illnesses, provide preventive and curative care and, report emergency cases to health center. However, the lack of information sharing and training support impedes the effectiveness of CHWs and their ability to correctly refer patients. We propose and describe a system for mobile and wearable computing devices called Remedy which assists CHWs in decision making and facilitates collaboration among them. Remedy can infer possible diseases and treatments by representing the diseases, their symptoms, and patient context in OWL ontologies and by reasoning over this model. The use of semantic representation of data makes it easier to share knowledge such as disease, symptom, diagnosis guidelines, and demography related information, between various personnel involved in health-care (e.g., CHWs, patients, health-care providers). We describe the Remedy system with the help of a motivating community health-care scenario and present an Android prototype for smart phones and Google Glass.
Ambivalent Encounters: Law and the Construction of Jewish Difference
Creators: name: Riedel, Mareike
Publisher: name: The Australian National University
Year: 2019

description: Despite the significance of the figure of 'the Jew' as Other in the Western imagination, critical legal scholarship has so far paid little attention to representations of Jews, Jewishness, and Judaism in contemporary legal discourse. This scholarship emphasises the role of law in the construction of religious and racial difference, but Jews have remained almost absent from such analyses. Once Europe's paradigmatic non-Christian minority, Jews are today seen increasingly as a successful, accepted, and well-integrated model-minority. A growing number of legal conflicts over Jewish practices, such as male circumcision, kosher slaughter, or the construction of eruvin (religious spaces in public for the observance of Shabbat) suggests however that tolerance for Jews can still be fragile and ideas about Jews as different persist. In this thesis, I explore law and legal discourse as a site for the construction of Jewish difference. Through a cultural study of law, I analyse two such contemporary legal conflicts concerning Jewish practices - the German controversy over the legality of male circumcision and an Australian dispute regarding the construction of an eruv in a Sydney suburb. Informed by critical law and religion scholarship, critical race theory, and Jewish studies, I explore images and representations of 'the Jew' in these encounters through a historically contextualised reading of the legal narratives presented by opponents of male circumcision and the eruv. Instead of focussing on Antisemitic imagery, I draw on the notion of ambivalence as a lens in order to capture a range of different attitudes - all of which perceive Jews as different. In each case, I identify the legal techniques through which Jews are rendered as different, thereby providing yet another challenge to the persistent myth of law's neutrality, universality, and objectivity. What emerges from these two case studies is not only the enduring relevance of ideas about Jews as Others and their fluid construction, but also the significance of law and legal discourse as an authoritative and powerful site for this construction. The thesis concludes by highlighting the importance of integrating the Jewish experience into scholarly theorising of the relation between law, religion, and race, allowing us to understand the dynamic nature of exclusion and inclusion as well as the role of law as a site for resistance to exclusion.
High-resolution Near-infrared Spectroscopic Study of Galactic Supernova Remnants. I. Kinematic Distances

description: We have carried out high-resolution near-infrared spectroscopic observations toward 16 Galactic supernova remnants (SNRs) showing strong H$_{2}$ emission features. A dozen bright H$_{2}$ emission lines are clearly detected for individual SNRs, and we have measured their central velocities, line widths, and fluxes. For all SNRs except one (G9.9$-$0.8), the H$_{2}$ line ratios are well consistent with that of thermal excitation at $T\sim2000$ K, indicating that the H$_{2}$ emission lines are most likely from shock-excited gas and therefore that they are physically associated with the remnants. The kinematic distances to the 15 SNRs are derived from the central velocities of the H$_{2}$ lines using a Galactic rotation model. We derive for the first time the kinematic distances to four SNRs: G13.5$+$0.2, G16.0$-$0.5, G32.1$-$0.9, and G33.2$-$0.6. Among the remaining 11 SNRs, the central velocities of the H$_{2}$ emission lines for six SNRs are well consistent ($\pm5$ km s$^{-1}$) with those obtained in previous radio observations, while for the other five SNRs (G18.1$-$0.1, G18.9$-$1.1, Kes 69, 3C 396, W49B) they are significantly different. We discuss the velocity discrepancies in these five SNRs. In G9.9$-$0.8, the H$_{2}$ emission shows nonthermal line ratios and narrow line width ($\sim 4$ km s$^{-1}$), and we discuss its origin.

Structure of the Cascadia subduction zone off Vancouver Island : new evidence from seismic refraction data

Publisher: name: University of British Columbia

description: The Cascadia subduction zone forms the present convergent margin between the North American plate and the oceanic Gorda, Juan de Fuca and Explorer plates from approximately 40°N to 50°N. This thesis examines a subset of the offshore-onshore seismic refraction/wide-angle reflection data recorded during the RECAP'89 (Reflectionrefraction Experiment: Cascadia Accretionary Prism). RECAP'89 was a "piggyback" experiment in which The University of British Columbia deployed four continuous recording seismographs at eight land sites on the west coast of Vancouver Island to record airgun shots fired during an offshore multichannel reflection survey acquired by the Geological Survey of Canada. An iterative combination of two-dimensional travel time inversion and amplitude forward modelling was used to interpret crust and upper mantle P-wave velocity structure. With the aid of interpretation of corresponding reflection data, velocity structures were developed for Line 89-02/03 and 89-09 in Cascadia subduction zone. The principal tectonic elements for which velocity structures are determined are (i) the Pacific Rim with an average velocity of 5.0-6.2 km/s, and Crescent terranes with an average velocity of 4.5-6.4 km/s, which He along the coast against and beneath Wrangellia, (ii) the Accreted Wedge with an average velocity of 4.1-5.0 km/s below Tofino Basin, (iii) the subducting Juan de Fuca plate with an average velocity of 6.1-7.0 km/s. The new velocity models are consistent with the gravity field constraints. The final velocity model of Line 89-02/03 indicates a possible position for the updip limit of the seismic rupture zone for a potential great thrust earthquake in the area. This new improved velocity structure would also help to determine more accurate earthquake locations for the region.

description: Positive mood predicts a broad range of psychological correlates of well-being in children. The present study examined the effects of positive mood on 3 components of social information processing (SIP) in young children including cue encoding, cue interpretation, and response access. The study hypothesized that positive mood and positive emotionality would have main effects on global orientation, response access, and socially competent responding and would also have an interactive effect on these variables. It was also hypothesized that anger would increase anger attribution bias. A computer game, during which participants won or unfairly lost toys, was used to induce happiness and anger in 104 participants recruited from Head Start Centers in urban communities. Participants also were exposed to a neutral stimulus during which they viewed pictures of everyday household and classroom objects. Friedman tests were used to examine the main and interactive effects of positive mood and positive emotionality on cue encoding and response access and the main effect of anger on cue interpretation. Spearman correlations were used to examine the relation between positive emotionality and SIP variables. Results indicated that positive mood has a positive main effect on global orientation and interacts with positive emotionality to predict global orientation such that the effect of positive mood is stronger and more positive for children higher in positive emotionality. Implications for these findings are discussed.

description: Farms that did not receive direct support from Federal farm programs in 1987 or 1988 totaled 1.4 million, or two-thirds of all farms. These farms did not receive payments because they either did not produce the program commodities or did not participate in farm programs. They accounted for about one-half of the land in farms and one-half of the sales of farm products in 1987. These data for 1987 and 1988 are the first such data published by the census of agriculture. They show that not all farmers receive support from the Government and that the characteristics of those who do not receive payments differ greatly from those of farmers who do.

description: We show that the solution of fully nonlinear lasing equations for stadium cavities exhibits a highly directional emission pattern. This directionality can be well explained by a ray-dynamical model, where the dominant ray-escape dynamics is governed by the unstable manifolds of the unstable short periodic orbits for the stadium cavity. Investigating the cold-cavity modes relevant for the lasing, we found that all of the high-Q modes have the emission directionality corresponding to that of the ray-dynamical model.

description: Tailoring spectral properties of photon pairs is of great importance for optical quantum information and measurement applications. High-resolution spectral measurement is a key technique for engineering spectral properties of photons, making them ideal for various quantum applications. Here we demonstrate spectral measurements and optimization of frequency-entangled photon pairs produced via spontaneous parametric downconversion (SPDC), utilizing frequency-resolved sum-frequency generation (SFG), the reverse process of SPDC. A joint phase-matching spectrum of a nonlinear crystal around 1580 nm is captured with a 40 pm resolution and a > 40 dB signal-to-noise ratio, significantly improved compared to traditional frequency-resolved coincidence measurements. Moreover, our scheme is applicable to collinear degenerate sources whose characterization is difficult with previously demonstrated stimulated difference frequency generation (DFG). We also illustrate that the observed phase-matching function is useful for finding an optimal pump spectrum to maximize the spectral indistinguishability of SPDC photons. We expect that our precise spectral characterization technique will be useful tool for characterizing and tailoring SPDC sources for a wide range of optical quantum applications

XML schema matching

description: One of the most critical steps to integrating heterogeneous e-Business applications using different XML schemas is schema matching, which is known to be costly and error-prone. Many automatic schema matching approaches have been proposed, but the challenge is still daunting because of the complexity of schemas and immaturity of technologies in semantic representation, measuring, and reasoning. The dissertation focuses on three challenging problems in schema matching. First, the existing approaches have often failed to sufficiently investigate and utilize semantic information imbedded in the hierarchical structure of the XML schemas. Secondly, due to synonyms and polysemies found in natural languages, the meaning of a data node in the schema cannot be determined solely by the words in its label. Thirdly, it is difficult to correctly identify the best set of matching pairs for all data nodes between two schemas. To overcome these problems, we propose new innovative approaches for XML schema matching, particularly applicable to XML schema integration and data transformation between heterogeneous e-Business systems. Our research supports two different tasks: integration task between two different component schemas; and transformation task between two business documents which confirm to different document schemas. For the integration task, we propose an approximate approach that produces the best matching candidates between global type components of two schemas, using their layer specific semantic similarities. For the transformation task, we propose another approximate approach that produces the best sets of matching pairs for all atomic nodes between two schemas, based on their linguistic and structural semantic similarities. We evaluate our approaches with the state of the art evaluation metrics and sample schema sets obtained from several e-Business standard organizations and e-Business system vendors. A variety of computer experiments have been conducted with encouraging results that show the proposed approaches are valuable for addressing difficulties in XML schema matching.
Structure of the Eastern Coast Belt, southwestern Canadian Cordillera, from reproducing lithoprobe seismic reflection lines 88-17 and 88-14

description: As part of the Lithoprobe Southern Cordillera research program, seismic reflection data were acquired in 1988 along a 100 km profile across the Eastern and Central Coast Belts (lines 88-14 and 88-17) in a region of complex surface geology. A very good interpretation of the crustal section based on previous processing by industry has been made. However, the data were not processed specifically to enhance the features in the upper 5 s and provide a clear tie to surface geology, some of which is newly studied since the earlier interpretation. The present study involves reprocessing of these data to provide this enhancement. Severe crookedness of the line necessitated the implementation of unconventional processing techniques, including creation of several mini-profiles which cut through the midpoint scatter and application of a first-order correction for effects of reflector crossdip ( i.e., the crossline component of reflector dip). Refraction-based statics were computed using a two-step procedure consisting of initial identification and correction of systematic errors in the picked first break traveltimes, and subsequent application of a 2-D statics algorithm. Dip moveout (DMO) was applied to constant-offset gathers to effect prestack partial migration and reduce the dependence of normal moveout velocity on reflector dip. To reduce possible smearing in the upper few seconds, stacks were repeated with truncated spread lengths. The Karhunen-Loeve transform was applied efficiently and economically on the stacked seismic data to enhance coherent signals in all selected dips. The reprocessing has better delineated the subsurface geometry of the terranes and faults and expressed some of the structures which are not visible on previous processing sections, even though the 2-D seismic images cannot completely express the 3-D complexity inferred from the surface geology. The reprocessed sections are considered in light of the new geological mapping to provide a refined interpretation of subsurface structure and its implication for local tectonics. A new geological model is developed based on this refined interpretation and is being further tested by seismic forward modeling.

description: For any recurrent random walk (S_n)_{n>0} on R, there are increasing sequences (g_n)_{n>0} converging to infinity for which (g_n S_n)_{n>0} has at least one finite accumulation point. For one class of random walks, we give a criterion on (g_n)_{n>0} and the distribution of S_1 determining the set of accumulation points for (g_n S_n)_{n>0}. This extends, with a simpler proof, a result of K.L. Chung and P. Erdos. Finally, for recurrent, symmetric random walks, we give a criterion characterizing the increasing sequences (g_n)_{n>0} of positive numbers for which liminf g_n|S_n|=0.
