Abstract:
Abstract This thesis project is divided in two parts. The first part examines the possibility that correlation matrix estimates based on an outlier sample would contain information about extreme events. According to my findings, such methods do not perform better than simple shrinkage methods where robust shrinkage targets are used. The method tested is especially outperformed when it comes to the extreme events, where a shrinkage of the correlation matrix towards the identity matrix seems to give the best result. The second part is about valuation of skewness in marginal distributions and the penalizing of heavy tails. I argue that it is reasonable to use a degrees of freedom parameter instead of kurtosis and a certain regression parameter, that I develop, instead of skewness due to robustness issues. When minimizing the one period draw-down is our target, the "value" of skewness seems to have a linear relationship with expected returns. Re-valuing of expected returns, in terms of skewness, in the standard Markowitz framework will tend to lower expected shortfall (ES), increase skewness and lower the realized portfolio variance. Penalizing of heavy tails will most times in the same way lower ES, lower kurtosis and realized portfolio variance. The results indicate that the parameters representing higher order moments in some way characterize the assets and also reflect their future behavior. These properties can be used in a simple optimization framework and seem to have a positive impact even on portfolio level

Abstract:
Microscopy as applied to the biological sciences has benefited tremendously in the last 50 years from the invention of optically sectioning microscopes. Many techniques for microscopy developed recently offer super-resolved imaging, but often at the cost of light efficiency, signal, acquisition speed or significant amounts of money. This thesis investigates further development of aperture correlation microscopy: a cheap, light-efficient, wide-field, optically sectioning, video-rate imaging technique until now incapable of super-resolution. An aperture correlation microscope was constructed, using a geometry consisting of 2 separate cameras permitting a larger field size than previous spinning disk aperture correlation systems. This microscope, operating at 16Hz (limited by the cameras) was then tested by imaging different samples and found to match reasonably well to the theory, while producing very clear images of biological samples. In order to power this aperture correlation microscope, an image registration algorithm must first register the frames from both cameras. We present a high-speed image registration algorithm suitable for fixed deformations, where a calibration pattern can first be imaged, by leveraging the graphics processing unit. In testing, this registration algorithm is capable of framerates of over 200Hz on modest hardware. A reflection correlation microscope was also constructed and characterised, operating at an illumination wavelength of 405nm, representing an advance into the UV for this technique. Synchronisation of camera acquisition and disk rotation allow for fast acquisition from a single camera. Measurements of its axial resolution match closely to the theory for 4 different illumination pattern pitches. Z-Stacks of transistor and Photovoltaic cell samples were taken in order to demonstrate this system's viability for imaging semiconductor devices. Finally, a novel type of aperture correlation microscope capable of super-resolution is designed and characterised, leveraging coherent illumination. It is demonstrated how tailoring the spatial frequencies present in the aperture mask can result in enhancement of high frequency information up to twice the diffraction limit. Transfer functions are measured, and found to match reasonably well with theory. Lateral resolution improvement of 1.5 times over conventional microscopy is seen here, paving the way for a new, highly efficient super-resolving microscope.

Abstract:
Korrelationskodierung im Hippokampus bildet möglicherweise die neuronale Basis für episodisches Gedächtnis. In dieser Arbeit untersuchen wir zwei Phänomene der Korrelationskodierung: Phasenpräzession und Sequenzwiederholungen. Phasenpräzession bezeichnet die Abnahme der Phase des Aktionspotentials einer Ortszelle relativ zur Theta-Oszillation. Sequenzwiederholung beschreibt die Aktivität von Ortszellen in Ruhephasen; dabei werden vorangegangene Orts- Sequenzen in umgekehrter Reihenfolge wiederholt. Wir untersuchen Phasenpräzession in einzelnen Versuchsdurchläufen. In bisherigen Studien wurden Daten zur Phasenpräzession in vielen Versuchsdurchläufen zusammengelegt. Wir zeigen, dass dies zu einer verzerrten Schätzung von grundlegenden Eigenschaften der Phasenpräzession führen kann. Weiterhin demonstrieren wir eine starke Variabilität der Phasenpräzession zwischen verschiedenen Versuchsdurchläufen. Daher ist Phasenpräzession besser geeignet zeitlich strukturierte Sequenzen zu lernen, als man aufgrund der zusammengelegten Daten vermutet hatte. Desweiteren untersuchen wir die Beziehung von Phasenpräzession in unterschiedlichen Teilen des Hippokampus. Wir zeigen, dass die extrazellulären Theta- Oszillationen in CA3 und CA1 außer Phase sind. Dennoch geschieht Phasenpräzession in beiden Regionen fast gleichzeitig, und CA3 Zellen feuern oft kurz vor CA1 Zellen. Diese zeitliche Beziehung ist im Einklang mit einer Vererbung von Phasenpräzession von CA3 nach CA1. Wir entwickeln ein mechanistisches Modell für Sequenzwiederholungen in umgekehrter Reihenfolge basierend auf Kurzzeitfazilitierung. Mit Hilfe des Tempotrons beweisen wir, dass die entstehenden zeitlichen Muster geeignet sind, um von nachgeschalteten Strukturen ausgelesen zu werden. Das Modell sagt voraus, dass im Gyrus Dentatus synchrone Zellaktivität kurz vor einer Sequenzwiederholung in CA3 zu sehen ist, und es zeigt, dass Sequenzwiederholungen zum Lernen von zeitlichen Mustern genutzt werden können.
Hippocampal correlation coding is a putative neural mechanism underlying episodic memory. Here, we look at two related phenomena: phase precession and reverse replay of sequences. Phase precession refers to the decrease of the firing phase of a place cell with respect to the local theta rhythm during the crossing of the place field. Reverse replay refers to reactivation of previously experienced place field sequences in reverse order during awake resting periods. First, we study properties of phase precession in single trials. Usually, phase precession is studied on the basis of data in which many place field traversals are pooled together. We find that single-trial and pooled-trial phase precession are different with respect to phase-position correlation, phase-time correlation, and phase range. We demonstrate that phase precession exhibits a large trial-to-trial variability and that pooling trials changes basic measures of phase precession. These findings indicate that single trials may be better suited for encoding temporally structured events than is suggested by the pooled data. Second, we examine the coordination of phase precession among subregions of the hippocampus. We find that the local theta rhythms in CA3 and CA1 are almost antiphasic. Still, phase precession in the two regions occurs with only a small phase shift, and CA3 cells tend to fire a few milliseconds before CA1 cells. These results suggest that phase precession in CA1 might be inherited from CA3. Finally, we present a model of reverse replay based on short-term facilitation. The model compresses temporal patterns from a behavioral time scale of seconds to shorter time scales relevant for synaptic plasticity. We demonstrate that the compressed patterns can be learned by the tempotron learning rule. The model provides testable predictions (synchronous activation of dentate gyrus during sharp wave-ripples) and functional interpretations of hippocampal activity (temporal pattern learning).

We study the problem of distributed correlation generators wherein n parties wish to simulate unbounded samples from a joint distribution D = Di x D2 X ... x D[subscript n], once they are initialized using randomness sampled from a (possibly different) correlated distribution. We wish to ensure that these samples are computationally indistinguishable from i.i.d. samples from D. Furthermore, we wish to ensure security even against an adversary who corrupts a subset of the parties and obtains their internal (initialization) state. Our contributions are three-fold. First, we define the notion of distributed (noninteractive) correlation generators and show its connection to other cryptographic primitives. Secondly, assuming the existence of indistinguishability obfuscators, we show a construction of distributed correlation generators for a large and natural class of joint distributions that we call conditionally sampleable distributions. Finally, we show a construction for the subclass of additive-spooky distributions assuming private constrained pseudorandom functions (private CPRFs).

Abstract:
Fluorescence correlation spectroscopy has become a standard technique for modern biophysics and single molecule spectroscopy research. Here is presented a novel widefield extension of the established single-point technique. Flow in microfluidic devices was used as a model system for microscopic motion and through widefield fluorescence correlation spectroscopy flow profiles were mapped in three dimensions. The technique presented is shown to be more tolerant to low signal strength, allowing image data with signal-to-noise values as low as 1.4 to produce accurate flow maps as well as utilizing dye-labeled single antibodies as flow tracers. With proper instrumentation flows along the axial direction can also be measured. Widefield fluorescence correlation spectroscopy has also been utilized to produce super-resolution confocal microscopic images relying on the single-molecule microsecond blinking dynamics of fluorescent silver clusters. A method for fluorescence modulation signal extraction as well as synthesis of several novel noble metal fluorophores is also presented.

Abstract:
In this article, we explore whether the evaluation instruments used to recruit teachers in the national teacher hiring process in Peru are good predictors of teacher effectiveness. To this end, we estimate teacher value-added (TVA) measures for public primary school teachers in 2018 and test for their correlation with the results of the 2015 and 2017 national evaluations. Our findings indicate that among the three sub-tests that comprise the first, centralized stage of the process, the curricular and pedagogical knowledge component has the strongest (and significant) correlation with the TVA measure, while the weakest correlation is found with the reading comprehension component. At the second, decentralized stage, we find no significant correlation with our measures of TVA for math, as well as non-robust correlations for the professional experience and classroom observation evaluation instruments. A positive and significant correlation is found between the classroom observation component and TVA for reading. Moreover, we find correlations between our measure of TVA and several teacher characteristics: TVA is higher for female teachers and for those at higher salary levels while it is lower for teachers with temporary contracts (compared to those with permanent positions).

Full text
Abstract:
This study investigates the temporal and spatio-temporal correlations of solar power generation among different prosumers of Uppsala and Halmstad, Sweden. Using solar power generation data from seven prosumer in Uppsala and five in Halmstad, we evaluate the correlation of solar power production generation at specific locations correlates with itself over different time lags (autocorrelation). In addition, we examine the spatiotemporal correlations of solar power production at various locations over a range of lags using time shifted cross correlation. These spatio-temporal correlations can facilitate the development of synchronized demand response strategies and dynamic energy pricing. Moreover, the timeshifted cross-correlation analysis assists in improving forecasting models for solar power generation. By identifying significant correlations between solar generation data from different locations and applying time shifts to account for variations in weather and sunlight exposure, operators can enhance the accuracy of their predictions. This methodology enables them to fill in missing data points by leveraging correlated information from neighboring regions. Consequently, more robust forecasting models can be developed, leading to better resource allocation, improved energy management, and reduced operational uncertainties in the grid. This research highlights the evaluation and potential of utilizing spatio-temporal and temporal correlations in solar power data to enhance energy management and planning.

Abstract:
The objective of this project was to either validate the current correlations or develop a new correlation that are used to compare compressor maps. Most compressor maps are presented at standard temperature and pressure. In order to compare data that is not collected at these conditions, correlations are used to relate the data to standard conditions. This project analyzes the validity of currently used correlations and provides improved correlations as needed.
