Troubles with Posthumanism
Creators: name: Bard, Imre
Year: 2010

description: Fortschritte im Bereich der Medizin und der Biotechnologie haben vorher als fundamental und solide geltenden Grenzziehungen, wie jene zwischen natürlich-künstlich oder lebendig-tot disloziert und verunsichert. Mit dem Verschwimmen der scharfen Trennung zwischen heilenden, restitutiven Eingriffen und verbessernden, optimierenden Massnahmen wird es allmählich möglich werden explizit in die „menschliche Natur“ einzugreifen um erwünschte Modifikationen zu unternehmen. Die Diplomarbeit beschäftigt sich mit dem Fragenkomplex der verbessernden Technologien und besteht aus drei Teilen. Zuerst soll eine historische Rekonstruktion der Idee der technologischen Verbesserung des Menschen gegeben werden. Es handelt sich um eine ideengeschichtliche Skizzierung die vor Augen führen wird, wie umfangreich die Geschichte dieser Idee ist und welche philosophische Strömungen auf gegenwärtige Positionen Einfluss ausgeübt haben. Diese geschichtliche Einführung führt zu den gegenwärtigen Debatten um die Normativität der menschlichen Natur, bzw. der Frage in welchem Verhältnis technologische Manipulationen zum Menschen stehen. Im zweiten Teil sollen also wichtige Autoren der aktuellen Debatte diskutiert werden, wie Jürgen Habermas und Francis Fukuyama, die von einer starken Normativität der menschlichen Natur ausgehen und meinen, dass die Grenzen der technologischen Verfügbarmachung in der menschlichen Natur liegen. Andererseits kommen auch solche Autoren zum Wort die in neuen technologischen Möglichkeiten eine Chance sehen die Schränke des Menschseins zu durchbrechen und eine helle „posthumane“ Zukunft einzuleiten. Auf der Grundlage von technikphilosophischen Argumenten wie jene von Donna Haraway und Katherine Hayles versucht die Arbeit die These stark zu machen, dass beide Positionen in der Debatte das ko-konstitutive Verhältnis zwischen Mensch und Technik viel zu wenig beachten. Beide Gruppen fassen Technik im Sinne eines Instruments auf mithilfe dessen die menschliche Natur entweder beschmutzt oder befreit werden kann. Im Gegensatz, scheinen Verbesserungs-, und konvergierenden Technologien andere Fragen aufzuwerfen, wenn wir das Verhältnis komplexer denken. Im dritten Teil wird Technik weder als Mittel zur Befreiung, noch als eine drohende Form der Instrumentalisierung und Entmenschlichung aufgefasst sondern etwas viel ambivalenteres das sowohl befreiende als auch potentiell unterdrückende Potentiale birgt. Rückgreifend auf Foucault´s Konzept der Biopolitik und der Governmentality Studies werden einige wichtige Züge der gegenwärtigen biopolitischen Landschaft diskutiert. Im Vordergrund stehen die Verallgemeinerung eines Risikodenkens und die wachsende Rolle vor preventiven Maßnahnamen und Screening-Verfahren.

Neo Rauch
Creators: name: Damianitsch, Stephanie
Year: 2010

description: Ziel dieser Arbeit ist es, Neo Rauchs Malerei als eine postmoderne Form des Historienbildes vorzustellen, welches auf den inhomogenen Erfahrungsraum unserer heutigen Gesellschaft antwortet. Über eine, auf semiologischen und strukturalistischen Theorien basierende Analyse seiner Werke - dabei stehen vor allem die Werke des Zeitraumzyklus (2006) im Vordergrund - soll aufgezeigt werden, dass Neo Rauch in der Gestaltung seiner Bilder einer historischen Methodik folgt, die die Geschichte selbst und seine spezifische Wahrnehmung von Geschichte über die Struktur seiner Werke reflektiert. Den Korrespondenzen und Unterschieden zur Historienmalerei der Leipziger Schule und der von Götz Großklaus analysierten zeitgenössischen, mediengenerierten Zeitwahrnehmung wird dabei ebenso nachgegangen, wie dem Vergleich Neo Rauchs Werke mit Walter Benjamins Kategorie des dialektischen Bildes, der es ermöglicht die Relevanz des stillgestellten, statischen Bildes - und damit des Mediums der Malerei - für Neo Rauchs Form der Geschichtsschreibung hervorzustreichen. Abseits der Idee eines linearen Zeitverlaufs und des Paradigmas des Fortschritts »konstruiert« Neo Rauch seine Historienbilder über ein affirmatives Verfahren der Aneignung, welches auf einem unwillkürlichen Erinnerungsprozess basiert und über das Neo Rauch bestrebt ist auf jene memorialen Zeichen des kollektiven Gedächtnisses zurückzugreifen, die unsere Vergangenheitskonstruktionen stützen. Aufgrund einer formalen Überarbeitung, die sich an den Mechanismen der Traumarbeit orientiert, erscheinen jene, an einer Ästhetik mit historischem Index partizipierenden Fragmente, als bruchstückhafte Spuren der Vergangenheit, in Schichtungen auf der Bildebene überlagert, sowie über relationale Verknüpfungen zueinander in Beziehung gesetzt. Abschließend kann festgestellt werden, dass die strukturelle Form seiner Werke - sowie deren dadurch bedingte Vielschichtigkeit und Multivalenz - der Ausdrucksweise der Allegorie entspricht, die als zentraler Repräsentationsmodus postmoderner Kunst gilt. Als Allegorien können Neo Rauchs Werke als postmoderne Historienbilder gedacht werden, die nicht die Normativität von Geschichte, sondern gerade deren Abwesenheit verhandeln und in denen unabgegoltene Vergangenheit, in synergetischer Beziehung zur Gegenwart stehend, erst »entdeckt« werden muss. Gleichzeitig macht der Künstler auf die, durch die mit Ideologien verbundenen Totalitätsansprüche bedingten Gefahren ehemaliger Konstruktionen von Geschichte - auch der Geschichte der Malerei in der Moderne - aufmerksam. Dadurch etabliert Neo Rauch über seine Bilder nicht nur ein kritisches und offenes Verständnis von Geschichte, sondern positioniert sich auch abseits des Diskurses eines Endes bzw. einer Rückkehr der Malerei.

description: The orientation of the disk of material accreting onto supermassive black holes that power quasars is one of most important quantities that are needed to understand quasars -- both individually and in the ensemble average. We present a hypothesis for determining comparatively edge-on orientation in a subset of quasars (both radio loud and radio quiet). If confirmed, this orientation indicator could be applicable to individual quasars without reference to radio or X-ray data and could identify some 10-20% of quasars as being more edge-on than average, based only on moderate resolution and signal-to-noise spectroscopy covering the CIV 1549A emission feature. We present a test of said hypothesis using X-ray observations and identify additional data that are needed to confirm this hypothesis and calibrate the metric.

Die filmische Darstellung der argentinischen Diktatur
Creators: name: Natter, Alexandra
Year: 2010

description: Die argentinische Diktatur, deren letzte Militärregierung bis 1984 andauerte, hat einen wesentlichen Einfluss auf die argentinische Filmgeschichte. Ziel dieser Arbeit ist es, die Hintergründe der Diktatur, anhand eines diskursanalytischen Zugangs, aufzuzeigen. Daraus leiten sich die Forschungsfragen ab: Wie wird die Diktatur im Film während der Diktatur, in den Exilfilmen und unmittelbar nach der Diktatur inszeniert? Im zweiten Teil der Arbeit erfolgt eine explizite Analyse des Filmes La Historia oficial. Als Grundgerüst hierbei dient die Filmanalyse nach Faulstich. Das Forschungsergebnis zielt auf die Inszenierung und Symbolik der Diktatur im Filmbeispiel ab. Am Ende soll, im speziellen anhand des Machtbegriffes nach Michel Foucault, die Aussage des Filmes aufgezeigt werden.

description: We describe the definition and the role background independence and the closely related notion of diffeomorphism invariance play in modern string theory. These important concepts are transformed by a new understanding of gauge redundancies and their implementation in non-perturbative quantum field theory and quantum gravity. This new understanding also suggests a new role for the so-called background-independent approaches to directly quantize the gravitational field. This article is intended for a general audience, and is based on a plenary talk given in the Loops 2007 conference in Morelia, Mexico.

description: We aim to study the nature of the faint, polarised radio source population whose source composition and redshift dependence contain information about the strength, morphology, and evolution of magnetic fields over cosmic timescales. We use a 15 pointing radio continuum L-band mosaic of the Lockman Hole, observed in full polarisation, generated from archival data of the WSRT. The data were analysed using the RM-Synthesis technique. We achieved a noise of 7 μJy/beam in polarised intensity, with a resolution of 15''. Using infrared and optical images and source catalogues, we were able to cross-identify and determine redshifts for one third of our detected polarised sources. We detected 150 polarised sources, most of which are weakly polarised with a mean fractional polarisation of 5.4 %. With a total area of 6.5 deg^2 and a detection threshold of 6.25 σ we find 23 polarised sources per deg^2. Based on our multi wavelength analysis, we find that our sample consists of AGN only. We find a discrepancy between archival number counts and those present in our data, which we attribute to sample variance. Considering the absolute radio luminosty, to distinguish weak and strong sources, we find a general trend of increased probability to detect weak sources at low redshift and strong sources at high redshift. Further, we find an anti-correlation between fractional polarisation and redshift for our strong sources sample at z{\geq}0.6. A decrease in the fractional polarisation of strong sources with increasing redshift cannot be explained by a constant magnetic field and electron density over cosmic scales, however the changing properties of cluster environments over the cosmic timemay play an important role. Disentangling these two effects requires deeper and wider polarisation observations, and better models of the morphology and strength of cosmic magnetic fields.

Ephemeroporus undetermined

description: 54. ** Ephemeroporus sp.
(Fig. 5A–F)
Localities and specimens found: 50 – 10♀, 2j; 51 – 4♀, 3♀ ov, 8j.
Distribution and ecology. These unidentified individuals of Ephemeroporus were found in the root system of floating macrophytes together with E. barroisi (see Appendix 1).
Remarks. These Ephemeroporus specimens require further careful study. It is possible that they belong to a new species still unknown. According to the complex of external features, these Vietnamese individuals do not correspond to any of the currently known species of the genus (Frey 1982b; Alonso 1987; Elmoor-Loureiro 2014; Sinev & Yusoff 2016; Korovchinsky et al. 2021b). First of all, they differ by a relatively long posterior basal spine on the postabdominal claw (about two-thirds of the length of the anterior spine) (Figs. 5A, D, E), as well as an unusually long lateral seta on the antennule (more than twice as long as the antennule) (Figs. 5A, B). None of the other species of Ephemeroporus have such long posterior basal spines on the claws and setae on the antennules (Frey 1982b; Alonso 1987; Elmoor-Loureiro 2014; Sinev & Yusoff 2016). With the presence of several denticles on the anterior margin of the labrum (Figs. 5A, C) and the absence of teeth on the posterior-ventral corner of the valves (Figs. 5A, F), this Ephemeroporus from Vietnam is similar to E. phintonicus (Margaritora, 1969) and E. tridentatus (Bergamin, 1939). However, apart from the general differences mentioned above, Ephemeroporus sp. does not have a group of enlarged marginal teeth proximally on the postanal part of the postabdomen (Figs. 5A, E), as in E. phintonicus and E. tridentatus (Frey 1982b). The appearance of the postabdominal claws in Ephemeroporus sp. (Figs. 5A, D, E) is very similar to that in Chydorus nitidulus (Sars, 1901), but the latter has a noticeably different shape and armament of the postabdomen, has a tooth on the posterior-ventral corner of the valves and does not have denticles on the anterior margin of the labrum (Frey 1982b).

description: The interpretation of potentially new and already known stellar structures located at low-latitudes is hindered by the presence of dense gas and dust, as observations toward these sight-lines are limited. We have identified APOGEE stars belonging to the low-latitude globular clusters 2MASS-GC02 and Terzan 4, presenting the first chemical element abundances of stars residing in these poorly studied clusters. As expected, the signature of multiple populations co-existing in these metal-rich clusters is evident. We redetermine the radial velocity of 2MASS-GC02 to be -87 +- 7 km/s, finding that this cluster's heliocentric radial velocity is offset by more than 150 km/s from the literature value. We investigate a potentially new low-latitude stellar structure, a kiloparsec-scale nuclear disk (or ring) which has been put forward to explain a high-velocity (V_{GSR} ~200 km/s) peak reported in several Galactic bulge fields based on the APOGEE commissioning observations. New radial velocities of field stars at (l,b)=(-6,0) are presented and combined with the APOGEE observations at negative longitudes to carry out this search. Unfortunately no prominent -200 km/s peak at negative longitudes along the plane of the Milky Way is apparent, as predicted for the signature of a nuclear feature. The distances and Gaia EDR3 proper motions of the high-V_{GSR} stars do not support the current models of stars on bar-supporting orbits as an explanation of the +200 km/s peak.

description: Fatty acid products derived from cytochromes P450 (CYP) monooxygenase and lipoxygenase (LOX)/CYP ω/(ω-1)-hydroxylase pathways are a superclass of lipid mediators with potent bioactivities. Whether or not the chronic kidney disease (CKD) and hemodialysis treatments performed on end-stage renal disease (ESRD) patients affect RBC epoxy fatty acids profiles remains unknown. Measuring the products solely in plasma is suboptimal. Since such determinations invariably ignore red blood cells (RBCs) that make up 3 kg of the circulating blood. RBCs are potential reservoirs for epoxy fatty acids that regulate cardiovascular function. We studied 15 healthy persons and 15 ESRD patients undergoing regular hemodialysis treatments. We measured epoxides derived from CYP monooxygenase and metabolites derived from LOX/CYP ω/(ω-1)-hydroxylase pathways in RBCs by LC–MS/MS tandem mass spectrometry. Our data demonstrate that various CYP epoxides and LOX/CYP ω/(ω-1)-hydroxylase products are increased in RBCs of ESRD patients, compared to control subjects, including dihydroxyeicosatrienoic acids (DHETs), epoxyeicosatetraenoic acids (EEQs), dihydroxydocosapentaenoic acids (DiHDPAs), and hydroxyeicosatetraenoic acids (HETEs). Hemodialysis treatment did not affect the majority of those metabolites. Nevertheless, we detected more pronounced changes in free metabolite levels in RBCs after dialysis, as compared with the total RBC compartment. These findings indicate that free RBC eicosanoids should be considered more dynamic or vulnerable in CKD.

description: Aims: Atrial contractile dysfunction contributes to worse prognosis in hypertensive heart disease (HHD), but the role of cardiomyocyte dysfunction in atrial remodelling in HHD is not well understood. We investigated and compared cellular mechanisms of left (LA) and right atrial (RA) contractile dysfunction in pigs with HHD. Methods and results: In vivo electrophysiological and magnetic resonance imaging studies were performed in control and pigs treated with 11-deoxycorticosterone acetate (DOCA)/high-salt/glucose diet (12 weeks) to induce HHD. HHD leads to significant atrial remodelling and loss of contractile function in LA and a similar trend in RA (magnetic resonance imaging). Atrial remodelling was associated with a higher inducibility of atrial fibrillation but unrelated to changes in atrial refractory period or fibrosis (histology). Reduced atrial function in DOCA pigs was related to reduced contraction amplitude of isolated LA (already at baseline) and RA myocytes (at higher frequencies) due to reduced intracellular Ca release (Fura 2-AM, field stimulation). However, Ca regulation differed in LA and RA cardiomyocytes: LA cardiomyocytes showed reduced sarcoplasmic reticulum (SR) [Ca], whereas in RA, SR [Ca] was unchanged and SR Ca2+-ATPase activity was increased. Sodium-calcium exchanger (NCX) activity was not significantly altered. We used ORM-10103 (3 mu M), a specific NCX inhibitor to improve Ca availability in LA and RA cardiomyocytes from DOCA pigs. Partial inhibition of NCX increased Ca2+ transient amplitude and SR Ca in LA, but not RA cells. Conclusions: In this large animal model of HHD, atrial remodelling in sinus rhythm in vivo was related to differential LA and RA cardiomyocyte dysfunction and Ca signalling. Selective acute inhibition of NCX improved Ca release in diseased LA cardiomyocytes, suggesting a potential therapeutic approach to improve atrial inotropy in HHD.
A BLR origin for the iron K$α$ line in NGC7213

description: The X-ray spectrum of NGC7213 is known to present no evidence for Compton reflection, a unique result among bright Seyfert 1s. The observed neutral iron K$α$ line, therefore, cannot be associated with a Compton-thick material, like the disc or the torus, but is due to Compton-thin gas, with the Broad Line Region (BLR) as the most likely candidate. To check this hypothesis, a long Chandra HETG observation, together with a quasi-simultaneous optical spectroscopic observation at the ESO NTT EMMI were performed. We found that the iron line is resolved with a FWHM=$2 400^{+1 100}_{-600}$ km/s, in perfect agreement with the value measured for the broad component of the H$α$, $2640^{+110}_{-90}$ km/s. Therefore, NGC7213 is the only Seyfert 1 galaxy whose iron K$α$ line is unambiguously produced in the BLR. We also confirmed the presence of two ionised iron lines and studied them in greater detail than before. The resonant line is the dominant component in the Fe XXV triplet, therefore suggesting an origin in collisionally ionised gas. If this is the case, the blueshift of around 1000 km/s of the two ionised iron lines could be the first measure of the velocity of a starburst wind from its X-ray emission.

Influence of the adult eyes on circadian and lunar rhythms in Platynereis dumerilii
Creators: name: Keplinger, Stefan
Year: 2010

description: This study is concerned with the influence of the cerebral adult eyes on the lunar and circadian rhythmicity in Platynereis dumerilii. By means of UV-laser ablation adult eyes were destroyed and via qPCR the relative abundance of orthologue clock genes were measured throughout 24 hours. Due to this molecular read-out of the circadian clock genes the entrainability of blinded Platynereis dumerilii to an inverted day/night rhythm could be tested. The finding of newly discovered ocelli in Platynereis dumerilii might suggest a role for them in circadian entrainment.

Mittels UV-Laser-Ablation wurden die cerebralen Adultaugen zerstört und mittels qPCR die Genexpression orthologer "clock" gene über 24 Stunden gemessen. Durch dieses molekulare Auslesen der circadianen clock in Platynereis dumerilli wurden die blinde Tiere auf ihre Anpassungsfähigkeit auf einen exakt invertieren Tag/Nacht Rhythmus getestet. Die Entdeckung neuer rhabdomerer Ocelli in Platynereis dumerilii lässt eine Rolle dieser im circadianem entrainment plausibel erscheinen.

description: Objectives: Increasing the number of daily steps by using a pedometer and a diary leads to an activity increase and improved health outcomes in a variety of somatic disorders. Hence, for the inpatient treatment of depression, supervised exercise interventions are more widespread. We aim to examine if a self-managed pedometer intervention (PI) with the option of being proceeded after discharge leads to reduction of depression and to a physical activity (PA) increase. Methods: The Step Away from Depression (SAD) study is a multicenter randomized controlled trial targeting 400 patients with major depressive disorder. Treatment as usual (TAU) is compared to TAU plus PI after 4 weeks, at discharge, and 6 months after hospital admission. Primary outcomes are clinically rated depression severity and accelerometer-measured step counts. Secondary outcomes include self-reported depression symptoms and PA level, psychiatric symptoms, health-related quality of life, self-efficacy, and components of the Motivation Volition Process Model. Results: We report the design of the SAD study considering several methodological aspects for exercise studies, in general. Conclusions: Results of our study will provide information about efficacy of PI for inpatient treatment and about interrelating processes of change concerning depression, PA, and aspects of motivation and volition.

description: We propose and experimentally prove efficient high-resolution electro-optic sampling measurement of broadband terahertz waveforms in a LiNbO$_3$ crystal in the configuration with the probe laser beam propagating along the optical axis of the crystal. This configuration allows one to avoid the detrimental effect of strong intrinsic birefringence of LiNbO$_3$ without any additional optical elements. To achieve velocity matching of the terahertz wave and the probe beam, the terahertz wave is introduced into the crystal through a Si prism at the Cherenkov angle to the probe beam. The workability of the scheme at different wavelengths of the probe optical beam (800 and 1550 nm) is demonstrated.

description: Abstract machine definitions have been recognized as convenient and powerful tools for enhancing software portability. One such machine, the Inter lisp Virtual Machine, is examined in this thesis. We present the Multilisp System as an implementation of the Virtual Machine and discuss some of the design criteria and difficulties encountered in mapping the Virtual Machine onto a particular environment. On the basis of our experience with Multilisp we indicate several weaknesses of the Virtual Machine which impair its adequacy as a basis for a portable Interlisp System.

description: The phase diagrams at high temperature of SU(N) gauge theories with massive fermions are calculated by numerically minimizing the one-loop effective potential. We consider fermions in the Fundamental (F), Adjoint (Adj), Antisymmetric (AS), and Symmetric (S) representations, for N from 3 to 9, with periodic and antiperiodic boundary conditions applied. For one flavour of AS/S (Dirac) fermion with periodic boundary conditions the C-breaking phase is favoured perturbatively for all values of the fermion mass. In the case of one flavour of adjoint Majorana fermion, and periodic boundary conditons, the deconfined phase is favoured for any fermion mass. For one or more adjoint Dirac fermion (two or more Majorana fermions) we find partially-confining phases as well as new phases with unusual properties. Our results for SU(3) and SU(4) are consistent with our lattice simulations of a related model.

description: We optimize number squeezing when splitting a mesoscopic Bose Einstein condensate. Applying optimal control theory to a realistic description of the condensate allowed us to identify a form of the splitting ramp which drastically outperforms the adiabatic splitting. The results can be interpreted in terms of a generic two-mode model mapped onto a parametric harmonic oscillator. This optimal route to squeezing paves the way to a much longer phase coherence and atom interferometry close to the Heisenberg limit.

description: Criticality has been conjectured as an integral part of neuronal network dynamics. Operating at a critical threshold requires precise parameter tuning and a corresponding mechanism remains an open question. Recent studies have suggested that topological features observed in brain networks give rise to a Griffiths phase, leading to power-law scaling in brain activity dynamics and the operational benefits of criticality in an extended parameter region. Motivated by growing evidence of neural correlates of different states of consciousness, we investigate how topological changes affect the expression of a Griffiths phase. We analyze the activity decay in modular networks using a susceptible-infected-susceptible propagation model and find that we can control the extension of the Griffiths phase by altering intra- and intermodular connectivity. We find that by adjusting system parameters, we can counteract changes in critical behavior and maintain a stable critical region despite changes in network topology. Our results give insight into how structural network properties affect the emergence of a Griffiths phase and how its features are linked to established topological network metrics. We discuss how those findings could contribute to an understanding of the changes in functional brain networks.

description: We have measured the cross section $σ(e^+e^-\toπ^+π^-γ(γ))$ at DA$Φ$NE, the Frascati ϕ-factory, using events with initial state radiation photons emitted at small angle and inclusive of final state radiation. We present the analysis of a new data set corresponding to an integrated luminosity of 240 pb$^{-1}$. We have achieved a reduced systematic uncertainty with respect to previously published KLOE results. From the cross section we obtain the pion form factor and the contribution to the muon magnetic anomaly from two pion states in the mass range $0.592 < M_{ππ} < 0.975$ GeV. For the latter we find $Δa^{ππ}_μ= (387.2\pm0.5_{\rm stat}\pm2.4_{\rm exp}\pm2.3_{\rm th})\times 10^{-10}$

description: We present results from a detailed experimental investigation of LaFeAsO, the parent material in the series of "FeAs" based oxypnictide superconductors. Upon cooling this material undergoes a tetragonal-orthorhombic crystallographic phase transition at ~160 K followed closely by an antiferromagnetic ordering near 145 K. Analysis of these phase transitions using temperature dependent powder X-ray and neutron diffraction measurements is presented. A magnetic moment of ~0.35 Bohr magnetons per iron is derived from Mossbauer spectra in the low temperature phase. Evidence of the structural transition is observed at temperatures well above the structural transition (up to near 200 K) in the diffraction data as well as the polycrystalline elastic moduli probed by resonant ultrasound spectroscopy measurements. The effects of the two phase transitions on the transport properties (resistivity, thermal conductivity, Seebeck coefficient, Hall coefficient), heat capacity, and magnetization of LaFeAsO are also reported, including a dramatic increase in the magnitude of the Hall coefficient below 160 K. The results suggest that the structural distortion leads to a localization of carriers on Fe, producing small local magnetic moments which subsequently order antiferromagnetically upon further cooling. Evidence of strong electron-phonon interactions in the high-temperature tetragonal phase is also observed.

description: Amorphous gallium oxide thin films were grown by plasma-enhanced atomic layer deposition on (100) silicon substrates from trimethylgallium Ga(CH3)3 precursor and oxygen plasma. At 200 °C, the growth per cycle is in the range of 0.65–0.70 Å for O2 plasma exposure times ranging from 3 up to 30 s during each cycle. The effect of O2 plasma exposure times on the interfacial SiOx regrowth and the electrical properties was investigated. In situ spectroscopic ellipsometry shows that the SiOx regrowth occurs during the first three cycles and is limited to 0.27 nm for plasma times as long as 30 s. Increasing the O2 plasma exposure during each ALD cycle leads to a drastic decrease in the leakage current density (more than 5 orders of magnitude for 30 nm films), which is linked to the suppression of oxygen vacancy states as evidenced by spectroscopic ellipsometry. Interestingly, an increase in the dielectric constant with increasing O2 plasma exposure time is observed, reaching a value of 𝜀𝑟∼14.2, larger than that of single crystalline β-Ga2O3. This study highlights the crucial role of oxygen plasma exposure time in the control and tuning of the electrical properties of amorphous gallium oxide films.

description: The rho Oph molecular cloud is undergoing intermediate-mass star formation. UV radiation from its hottest young stars heats and dissociates exposed layers, but does not ionize hydrogen. Only faint radiation from the Rayleigh-Jeans tail of ~10-100K dust is expected at wavelengths longwards of 3mm. Yet Cosmic Background Imager (CBI) observations reveal that the rho Oph W photo-dissociation region (PDR) is surprisingly bright at centimetre wavelengths. We searched for interpretations consistent with the WMAP radio spectrum, new ISO-LWS parallel mode images and archival Spitzer data. Dust-related emission mechanisms at 1 cm, as proposed by Draine & Lazarian, are a possibility. But a magnetic enhancement of the grain opacity at 1cm is inconsistent with the morphology of the dust column maps Nd and the lack of detected polarization. Spinning dust, or electric-dipole radiation from spinning very small grains (VSGs), comfortably explains the radio spectrum, although not the conspicuous absence from the CBI data of the infrared circumstellar nebulae around the B-type stars S1 and SR~3. Allowing for VSG depletion can marginally reconcile spinning dust with the data. As an alternative interpretation we consider the continuum from residual charges in rho Oph W, where most of carbon should be photoionised by the close binary HD147889 (B2IV, B3IV). Electron densities of ~100 cm^{-3}, or H-nucleus densities n_H > 1E6 cm^{-3}, are required to interpret rho Oph W as the CII Stromgren sphere of HD147889. However the observed steep and positive low-frequency spectral index would then require optically thick emission from an hitherto unobserved ensemble of dense clumps or sheets with a filling factor ~1E-4 and n_H ~ 1E7 cm^{-3}.

The application of optimal stochastic control theory to adaptive performance control of computer systems
Creators: name: Lo, Nyuk Leong
Publisher: name: University of British Columbia

description: This thesis applies optimal stochastic control theory, a well-known engineering technique, to adaptive performance control of computer systems. The major advantages of using the theory to adaptive performance control of computer systems are: a) the policy so obtained can be shown mathematically to give optimal performance, b) the policy is dynamic in the sense that control decisions are made based on the current system state thus optimizing performance at all time, c) once a stochastic model of a system has been developed it can be used to determine optimal policies pertaining to different criteria simply by using different objective functions in the model. The application is exemplified by using the theory to compute the optimal admission policy for a combined batch-interactive system with paging. A mathematical model of the system was developed and the theory applied to compute the optimal admission policy. The policy determines the number of batch and interactive jobs that should be activated at each system state. The solution is shown to exhibit the following properties: i) It maximizes the total system throughput. ii) It gives good mean response time to interactive jobs. iii) It guarantees a minimium level of batch throughput. The improvement in total system throughput compared to the case when jobs are automatically admitted on arrival is substantial. The improvement is most dramatic when the workload is heavy.

description: An assessment of variance in ocean current signal and noise shared by in situ observations (drifters) and a large gridded analysis (GlobCurrent) is sought as a function of day of the year for 1993-2015 and across a broad spectrum of current speed. Regardless of the division of collocations, it is difficult to claim that any synoptic assessment can be based on independent observations. Instead, a measurement model that departs from ordinary linear regression by accommodating error correlation is proposed. The interpretation of independence is explored by applying Fuller's (1987) concept of equation and measurement error to a division of error into shared (correlated) and unshared (uncorrelated) components, respectively. The resulting division of variance in the new model favours noise. Ocean current shared (equation) error is of comparable magnitude to unshared (measurement) error and the latter is, for GlobCurrent and drifters respectively, comparable to ordinary and reverse linear regression. Although signal variance appears to be small, its utility as a measure of agreement between two variates is highlighted. Sparse collocations that sample a dense grid permit a first order autoregressive form of measurement model to be considered, including parameterizations of analysis-in situ error cross-correlation and analysis temporal error autocorrelation. The former (cross-correlation) is an equation error term that accommodates error shared by both GlobCurrent and drifters. The latter (autocorrelation) facilitates an identification and retrieval of all model parameters. Solutions are sought using a prescribed calibration between GlobCurrent and drifters (by variance matching). Because the true current variance of GlobCurrent and drifters is small, signal to noise ratio is near zero at best. This is particularly evident for moderate current speed and meridional current component.
