description: It is well-known that light bridges inside a sunspot produce small-scale plasma ejections and transient brightenings in the chromosphere, but the nature and origin of such phenomena are still unclear. Utilizing the high-spatial and high temporal resolution spectral data taken with the Fast Imaging Solar Spectrograph and the TiO 7057 A broadband filter images installed at the 1.6 meter New Solar Telescope of Big Bear Solar Observatory, we report arcsecond-scale chromospheric plasma ejections (1.7 arc) inside a light bridge. Interestingly, the ejections are found to be a manifestation of upwardly propagating shock waves as evidenced by the sawtooth patterns seen in the temporal-spectral plots of the Ca II 8542 A and H-alpha intensities. We also found a fine-scale photospheric pattern (1 arc) diverging with a speed of about 2 km/s two minutes before the plasma ejections, which seems to be a manifestation of magnetic flux emergence. As a response to the plasma ejections, the corona displayed small-scale transient brightenings. Based on our findings, we suggest that the shock waves can be excited by the local disturbance caused by magnetic reconnection between the emerging flux inside the light bridge and the adjacent umbral magnetic field. The disturbance generates slow-mode waves, which soon develop into shock waves, and manifest themselves as the arcsecond-scale plasma ejections. It also appears that the dissipation of mechanical energy in the shock waves can heat the local corona.

description: The effect of the $\ord{\partial^4}$ terms of the gradient expansion on anomalous dimension $η$ and the correlation length's critical exponent $ν$ of the Wilson-Fisher fixed point has been determined for the Euclidean $O(N)$ model for $N=1$ and the number of dimensions $2< d<4$ as well as for $N\ge 2$ and $d=3$. Wetterich's effective average action renormalization group method is used with field-independent derivative couplings and Litim's optimized regulator. It is shown that the critical theory for $N\ge 2$ is well approximated by the effective average action preserving $O(N)$ symmetry with the accuracy of $\ordη$.

description: Postpartum disease is a common occurrence in the dairy cow. Nationally about 7% of calvings and 15% of culls occur in the first 30 days postpartum. Metritis is one of the most common diseases of the postpartum period. Metritis has been shown to occur as often as 37.3% of the time (Markusfeld 2007). Monitoring of the rectal temperature of dairy cows for the first 10 days post partum is a common recommendation (100 day contract Pfizer Animal Health). Treatment with antibiotics is often recommended to be initiated if temperatures are greater than 103 to 104°F. The purpose of this study was to determine the temperature of lactating dairy cows in the first two weeks postpartum, and evaluate temperature as an indication of the need for antibiotic therapy for the treatment of metritis.

description: In this work we investigate a $Z_2$ symmetric model of one scalar field $ϕ$ in $(1,1)$ dimension. The model is characterized by a continuous transition from a potential $V(ϕ)$ with two vacua to the vacuumless case. The model has kink and antikink solutions that minimize energy. Stability analysis are described by a Schrödinger-like equation with a potential that transits from a volcano-shape with no vibrational states (in the case of vacuumless limit) to a smooth valley with one vibrational state. We are interested on the structure of 2-bounce windows present in kink-antikink scattering processes. The standard mechanism of Campbell-Schonfeld-Wingate (CSW) requires the presence of one vibrational state for the occurrence of 2-bounce windows. We report that the effect of increasing the separation of vacua from the potential $V(ϕ)$ has the consequence of trading some of the first 2-bounce windows predicted by the CSW mechanism by false 2-bounce windows. Another consequence is the appearance of false 2-bounce windows of zero-order.

description: A formulation of linearized gravity in flat background, based on the Fierz tensor as a counterpart of the electromagnetic field strength, is discussed in detail and used to study fundamental properties of the linearized gravitational field. In particular, the linearized Einstein equations are written as first order partial differential equations in terms of the Fierz tensor, in analogy with the first order Maxwell equations. An energy-momentum tensor ($T_{\mathrm{lg}}^{ab}$) with favourable properties and exhibiting remarkable similarity to the standard energy-momentum tensor of the electromagnetic field is found for the linearized gravitational field. $T_{\mathrm{lg}}^{ab}$ is quadratic in the Fierz tensor (which is constructed from the first derivatives of the linearized metric), traceless, and satisfies the dominant energy condition in a gauge that contains the transverse traceless gauge. It is further shown that in suitable gauges, including the transverse traceless gauge, linearized gravity in the absence of matter has a duality symmetry that maps the Fierz tensor, which is antisymmetric in its first two indices, into its dual. Conserved currents associated with the gauge and duality symmetries of linearized gravity are also determined. These currents show good analogy with the corresponding currents in electrodynamics.

description: The purpose of this work is to better understand the confidence limits of the photospheric solar oxygen abundance derived from three-dimensional models using the forbidden [OI] line at 6300 Å, including correlations with other parameters involved. We worked with a three-dimensional empirical model and two solar intensity atlases. We employed Bayesian inference as a tool to determine the most probable value for the solar oxygen abundance given the model chosen. We considered a number of error sources, such as uncertainties in the continuum derivation, in the wavelength calibration and in the abundance/strength of Ni. Our results shows correlations between the effects of several parameters employed in the derivation. The Bayesian analysis provides robust confidence limits taking into account all of these factors in a rigorous manner. We obtain that, given the empirical three-dimensional model and the atlas observations employed here, the most probable value for the solar oxygen abundance is $\log(ε_O) = 8.86\pm0.04$. However, we note that this uncertainty does not consider possible sources of systematic errors due to the model choice.

description: Non-equilibrium dynamics of strongly correlated systems constitutes a fascinating problem of condensed matter physics with many open questions. Here we investigate the relaxation dynamics of Landau-quantized electron system into spin-valley polarized ground state in a gate-tunable MoSe$_2$ monolayer subjected to a strong magnetic field. The system is driven out of equilibrium with optically injected excitons that depolarize the electron spins and the subsequent electron spin-valley relaxation is probed in time-resolved experiments. We demonstrate that the relaxation rate at millikelvin temperatures sensitively depends on the Landau level filling factor: it becomes faster whenever the electrons form an integer quantum Hall liquid and slows down appreciably at non-integer fillings. Our findings evidence that valley relaxation dynamics may be used as a tool to investigate the interplay between the effects of disorder and strong interactions in the electronic ground state.

description: The goal of this study was to evaluate the ability of a commercially-available feed supplement (OmniGen-AF) to reduce development of mastitis in a mouse mastitis model. The rationale for completing this study was two-fold. First, dairy producers have reported that OmniGen-AF reduced somatic cell counts and reduced mastitis after the introduction of the product into herds. Second, recent studies have shown that the product increased markers of both innate and adaptive immunity. Our hypothesis, therefore, was that feeding the product would reduce the development and severity of mastitis in a mouse model. To assess this hypothesis, five experiments were completed with three bovine mastitis isolates. The isolates included Streptococcus uberis (S. uberis), Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus).

description: Wavefront aberrations are identified as a major limitation in quantum sensors. They are today the main contribution in the uncertainty budget of best cold atom interferometers based on two-photon laser beam splitters, and constitute an important limit for their long-term stability, impeding these instruments from reaching their full potential. Moreover, they will also remain a major obstacle in future experiments based on large momentum beam splitters. In this article, we tackle this issue by using a deformable mirror to control actively the laser wavefronts in atom interferometry. In particular, we demonstrate in an experimental proof of principle the efficient correction of wavefront aberrations in an atomic gravimeter.

description: No abstracts are to be cited without prior reference to the author.Adding extra information on the horizontal and vertical distribution of fish, both on and between trawl stations is reason enough to routinely perform acoustic surveys in tandem with annual groundfish trawl surveys. Ideally, acoustic and trawl density indices could be combined to maximise information fish distribution and provide more reliable estimates of stock size. The core of the problem boils down to the question: “How does what we see on an echosounder relate to what we catch in a net?' Founded on the premise that there ought to be some kind of relationship, the fuzzy logic ‘model-free estimation’ approach presented here side-steps the need to understand specific mechanisms that determine the nature and variability of any relationship between acoustic and trawl catches. We show the development of fuzzy logic models that describe and predict the relationship linking acoustics and other environmental variables (inputs) with trawl catches (output), and further discuss the sensitivities and robustness of the approach. In the models examined, location and depth proved to be a better predictor of the trawl catches in the North Sea than the acoustic energy in the first 5 meters off the bottom.

description: Low-mass (sub-eV) scalar field dark matter may induce apparent oscillations of fundamental constants, resulting in corresponding oscillations of the size and the index of refraction of solids. Laser interferometers are highly sensitive to changes in the size and index of refraction of the main beamsplitter. Using cross-correlated data of the Fermilab Holometer instrument, which consists of twin co-located 40-m arm length power-recycled interferometers, we investigate the possible existence of scalar field dark matter candidates in the mass range between 1.6$\cdot$10$^{-12}$ eV and 1.0$\cdot$10$^{-7}$ eV. We set new upper limits for the coupling parameters of scalar field dark matter, improving on limits from previous direct searches by up to three orders of magnitude.

description: In Canada, mastitis treatment accounts for more than half of all antibiotics used by dairy producers. Treatment decisions are often made without knowledge of the pathogen, therefore, researchers have called for a more targeted approach to antibiotic therapy for clinical mastitis. The overall hypothesis of this project is that the use of rapid on-farm tools for the identification of mastitis pathogens will result in therapy decisions that will decrease antibiotic use, without compromising short or long term cow or herd mastitis outcomes. The objective of this study was to determine test characteristics and compare two potential on-farm culture systems, the Minnesota Easy Culture System II Bi-plate (University of Minnesota, St. Paul, MN) and 3M Petrifilm™ (3M Microbiology, London, ON).

description: We present F-PKI, an enhancement to the HTTPS public-key infrastructure (or web PKI) that gives trust flexibility to both clients and domain owners, and enables certification authorities (CAs) to enforce stronger security measures. In today's web PKI, all CAs are equally trusted, and security is defined by the weakest link. We address this problem by introducing trust flexibility in two dimensions: with F-PKI, each domain owner can define a domain policy (specifying, for example, which CAs are authorized to issue certificates for their domain name) and each client can set or choose a validation policy based on trust levels. F-PKI thus supports a property that is sorely needed in today's Internet: trust heterogeneity. Different parties can express different trust preferences while still being able to verify all certificates. In contrast, today's web PKI only allows clients to fully distrust suspicious/misbehaving CAs, which is likely to cause collateral damage in the form of legitimate certificates being rejected. Our contribution is to present a system that is backward compatible, provides sensible security properties to both clients and domain owners, ensures the verifiability of all certificates, and prevents downgrade attacks. Furthermore, F-PKI provides a ground for innovation, as it gives CAs an incentive to deploy new security measures to attract more customers, without having these measures undercut by vulnerable CAs.

Among the conflict, its transformation and resistance, the spaces of reincorporation are not defined solely within the legal-political and administrative limits that often ignore the complex and heterogeneous nature that characterizes them; from the physical and symbolic layout in which spaces are organized and appropriated to the ways of life or the types of social relationships that are established to produce and reproduce collective and individual existence.

description: No abstracts are to be cited without prior reference to the author.Groundfish have a wide and variable distribution making the use of trawling alone a highly inadequate sampling method. Trawl data provide species identification and numbers over a very small area and habitat type while acoustic data provide a wider coverage of the ecosystem, but fail to identify species. Both methods provide essential information required for assessing fish stock abundance and distribution, but no systematic method of combining these data has yet been identified. Acoustic and trawl data were collected for both the North and Barents Seas and their relationships investigated using artificial neural networks (ANNs). ANNs are information processing systems that were inspired by the structure of the brain. They can incorporate multiple variables and explore complex interactions between variables in far greater depth than many traditional statistical techniques. This modelling tool has had many successes in environmental modelling and is increasingly being applied in situations where the underlying relationships are poorly known. Network architectures, optimisation of connection weights (learning), model validation, and the reasons for the difference in performance between the North Sea and Barents Sea models are discussed.

description: We study the real-time evolution of an electron influenced by intense electromagnetic fields using the time-dependent basis light-front quantization (tBLFQ) framework. We focus on demonstrating the non-perturbative feature of the tBLFQ approach through a realistic application of the strong coupling QED problem, in which the electromagnetic fields are generated by an ultra-relativistic nucleus. We calculate transitions of an electron influenced by such electromagnetic fields and we show agreement with light-front perturbation theory when the atomic number of the nucleus is small. We compare tBLFQ simulations with perturbative calculations for nuclei with different atomic numbers, and obtain the significant higher-order contributions for heavy nuclei. The simulated real-time evolution of the momentum distribution of an electron evolving inside the strong electromagnetic fields exhibits significant non-perturbative corrections comparing to light-front perturbation theory calculations. The formalism used in this investigation can be extended to QCD problems in heavy ion collisions and electron ion collisions.

description: We study an ensemble of strongly coupled electrons under continuous microwave irradiation interacting with a dissipative environment, a problem of relevance to the creation of highly polarized non-equilibrium states in nuclear magnetic resonance. We analyse the stationary states of the dynamics, described within a Lindblad master equation framework, at the mean-field approximation level. This approach allows us to identify steady state phase transitions between phases of high and low polarization controlled by the distribution of electronic interactions. We compare the mean-field predictions to numerically exact simulations of small systems and find good agreement. Our study highlights the possibility of observing collective phenomena, such as metastable states, phase transitions and critical behaviour in appropriately designed paramagnetic systems. These phenomena occur in a low-temperature regime which is not theoretically tractable by conventional methods, e.g., the spin-temperature approach.

description: No abstracts are to be cited without prior reference to the author.Jellyfish are gaining increasing prominence in many pelagic marine ecosystems worldwide. It has been argued that jellyfish-dominated communities will be the end-point in ecosystems perturbed by high fishing effort, and that increases in jellyfish abundance could be indicative of, and consequences of, climate-induced changes and/or regime shifts in pelagic ecosystems. Jellyfish are difficult to sample using conventional netting techniques, and data on changes in distribution and abundance are consequently sparse. Recent field observations and modelling studies have however shown that jellyfish can be detected acoustically at frequencies used routinely for fisheries surveys (18, 38, 120 and 200 kHz). Acoustic surveys might therefore provide a means for monitoring jellyfish populations but, prerequisite to this, echoes arising from jellyfish must be distinguishable from echoes returned by other scatterers. This paper presents multi-frequency acoustic data for two jellyfish that are common in the Namibian Benguela; Chrysaora hysoscella and Aequorea aequorea, and explores how characteristic acoustic signatures of jellyfish may enable these organisms to be discriminated acoustically from pelagic fish including horse mackerel (Trachurus trachurus capensis) and pilchard (Sardinops ocellatus). The ability to discriminate jellyfish and fish using multi-frequency acoustic data may lead to improved acoustic estimates of pelagic fish biomass (by reducing bias due to jellyfish echoes) and aid ecological investigations of jellyfish.

description: This paper presents Hierarchical Network Dissection, a general pipeline to interpret the internal representation of face-centric inference models. Using a probabilistic formulation, our pipeline pairs units of the model with concepts in our "Face Dictionary", a collection of facial concepts with corresponding sample images. Our pipeline is inspired by Network Dissection, a popular interpretability model for object-centric and scene-centric models. However, our formulation allows to deal with two important challenges of face-centric models that Network Dissection cannot address: (1) spacial overlap of concepts: there are different facial concepts that simultaneously occur in the same region of the image, like "nose" (facial part) and "pointy nose" (facial attribute); and (2) global concepts: there are units with affinity to concepts that do not refer to specific locations of the face (e.g. apparent age). We use Hierarchical Network Dissection to dissect different face-centric inference models trained on widely-used facial datasets. The results show models trained for different tasks learned different internal representations. Furthermore, the interpretability results can reveal some biases in the training data and some interesting characteristics of the face-centric inference tasks. Finally, we conduct controlled experiments on biased data to showcase the potential of Hierarchical Network Dissection for bias discovery. The results illustrate how Hierarchical Network Dissection can be used to discover and quantify bias in the training data that is also encoded in the model.

description: This work presents an evaluation study using a force feedback evaluation framework for a novel direct needle force volume rendering concept in the context of liver puncture simulation. PTC/PTCD puncture interventions targeting the bile ducts have been selected to illustrate this concept. The haptic algorithms of the simulator system are based on (1) partially segmented patient image data and (2) a non-linear spring model effective at organ borders. The primary aim is to quantitatively evaluate force errors caused by our patient modeling approach, in comparison to haptic force output obtained from using gold-standard, completely manually-segmented data. The evaluation of the force algorithms compared to a force output from fully manually segmented gold-standard patient models, yields a low mean of 0.12 N root mean squared force error and up to 1.6 N for systematic maximum absolute errors. Force errors were evaluated on 31,222 preplanned test paths from 10 patients. Only twelve percent of the emitted forces along these paths were affected by errors. This is the first study evaluating haptic algorithms with deformable virtual patients in silico. We prove haptic rendering plausibility on a very high number of test paths. Important errors are below just noticeable differences for the hand-arm system.

description: In den Originalarbeiten dieser Habilitationsschrift wurde untersucht inwieweit quantitativ messbare Veränderungen verschiedener Aspekte der menschlichen Wahrnehmung Aufschluss über die Pathophysiologie von Schmerzsyndromen und Bewegungsstörungen geben oder gar als diagnostischer Marker für spezifische Erkrankungen herangezogen werden können. Hierzu wurden Verfahren zur Erfassung der somatosensorischen Funktion und von internen prämotorischen Signalen genutzt. Wir konnten für das CRPS zeigen, dass die Druckschmerzschwellen nicht nur über der Muskulatur der betroffenen Extremität, sondern auch über den distalen Gelenken erniedrigt waren. Darüber hinaus korrelierte die erniedrigte Druckschmerzschwelle mit dem erhöhten periartikulären Knochenmetabolismus in der Spätphase der Drei-Phasen-Szintigraphie, was die Validität dieser psychophysikalischen Messung unterstreicht. Die Druckhyperalgesie über den Gelenken war hochspezifisch und sensitiv für das CPRS, so dass diese Untersuchung in Zukunft als diagnostische Ergänzung zu den rein klinischen Diagnosekriterien des CRPS genutzt werden könnte. Weiterhin phänotypisierten wir Patient:innen mit molekulargenetisch gesicherter hereditärer Erythromelalgie bei Mutationen im SCN9A Gen. Bemerkenswerterweise zeichneten die Betroffenen neben den für die Erkrankung klassischen paroxysmalen Schmerzattacken in den Extremitäten auch einen Dauerschmerz auf. Dieser könnte mit der Funktionsstörung der kleinkalibrigen Nervenfasern zusammenhängen, die wir in diesem Kollektiv mittels quantitativ sensorischer Testung detektierten. Bei isolierten fokalen Dystonien fanden wir wider Erwarten keinerlei Veränderung in behavioralen Markern als Korrelate für die kortikale Somatotopie in dystonen und nicht-betroffenen Arealen. Hier könnte eine zu geringe Sensitivität der Methode zur Detektion von Veränderungen in Bezug auf die untersuchte Körperregion eine Rolle gespielt haben. Ergänzend stellten wir fest, dass eine physikalische Dehnung der Haut, wie sie bei abnormen Körperhaltungen bei der Dystonie vorkommt, zu einer veränderten Wahrnehmung der Distanz zwischen zwei taktilen Reizen führt. Dies deutet darauf hin, dass keine korrigierenden top-down-Mechanismen existieren, welche zu einer Größenkonstanz taktiler Reize trotz Dehnung der Haut führen würden. Schließlich demonstrierten wir bei Patient:innen mit Tourette-Syndrom eine durch die Erkrankung beeinträchtigte Entwicklung der Fähigkeit zur Diskrimination interner prämotorischer Signale. Die gestörte Signaldetektion könnte zur Aufrechterhaltung der Erkrankung beitragen, aber auch einen möglichen Ansatzpunkt für behaviorale Therapien darstellen.
Peruvian working girls making movement

description: In this dissertation I show how Peruvian girls who work and are organized as members of MANTHOC in Lima and Cajamarca are well equipped to navigate power structures. I do this by first talking about how girls in MANTHOC, or MANTHOCas, define their identity as dignified workers and how this classification teaches them how to traverse often negative conceptualizations of them. I then talk about how in becoming part of this organization, girls have a space where they can learn how to participate politically inside and outside their child-led social movement. By transposing their worker identity into different ways that they identify, more experienced girls begin to embody the movement’s values and as such maintain its purpose. In doing so, these girls are capable of gaining access to a differential mode of consciousness they can use to navigate adult power. As this process is always shifting and evolving, not one girl’s lived experience is the same as another’s, but they are able to use Sandoval’s five technologies of resistance to create positive change locally and globally.
