description: After a decade of design and construction, South Africa's SKA-MID precursor MeerKAT has begun its science operations. To make full use of the widefield capability of the array, it is imperative that we have an accurate model of the primary beam of its antennas. We have taken available L-band full-polarization 'astro-holographic' observations of three antennas and a generic electromagnetic simulation and created sparse representations of the beams using principal components and Zernike polynomials. The spectral behaviour of the spatial coefficients has been modelled using discrete cosine transform. We have provided the Zernike-based model over a diameter of 10 deg averaged over the beams of three antennas in an associated software tool (EIDOS) that can be useful in direction-dependent calibration and imaging. The model is more accurate for the diagonal elements of the beam Jones matrix and at lower frequencies. As we get more accurate beam measurements and simulations in the future, especially for the cross-polarization patterns, our pipeline can be used to create more accurate sparse representations of MeerKAT beams.

Fisheries and Fishery Management in a Variable Climate

description: Fisheries around the world are in collapse despite decades of research and attempts to manage them. While conventional bioeconomic models of fishery depletion are well-understood, reversing these trends has proven to be a stubborn problem, even in the presence of science-based management regimes. My dissertation uses empirical tools to uncover new insights into the biophysical dynamics that may be preventing stocks from rebounding. I focus on the effects of environmental variability, which prevailing fishery management practices tend to overlook. Theoretically, variations in climate can create booms and busts in fish population that may be exacerbated if fishing practices don't adapt accordingly. To identify and quantify these linkages empirically, I draw on an understanding of climate dynamics, the biology of the stocks, and the specifics of fishing policies in the North Atlantic, where catch-size restrictions on key species lead to a lagged relationship between the climate signal and its effects on the fishery. Chapters 2 and 3 chart the impacts of climate variability on population dynamics, catch, and labor demand over time. Together they demonstrate that a failure to account for such variations is both hindering fishery management efforts and hurting fishing communities. Chapter 4 directly examines the efficacy of existing U.S. fishing policy, which is a model for fishing policies around the world. I find that while the policy is reducing catch, it has not driven the intended rebounds in biomass.

description: This paper presents ContrastWSD, a RoBERTa-based metaphor detection model that integrates the Metaphor Identification Procedure (MIP) and Word Sense Disambiguation (WSD) to extract and contrast the contextual meaning with the basic meaning of a word to determine whether it is used metaphorically in a sentence. By utilizing the word senses derived from a WSD model, our model enhances the metaphor detection process and outperforms other methods that rely solely on contextual embeddings or integrate only the basic definitions and other external knowledge. We evaluate our approach on various benchmark datasets and compare it with strong baselines, indicating the effectiveness in advancing metaphor detection.

description: Neutrino nucleus elastic scattering (νAel) with reactor neutrinos is an interaction under full quantum-mechanical coherence. It has not yet been experimentally observed. We present new results on the studies of νAel cross section with an electro-cooled p-type point-contact germanium detector at the Kuo-Sheng Reactor Neutrino laboratory. A total of (242)357 kg-days of Reactor ON(OFF) data at a detector threshold of 200 eVee in electron equivalent unit are analyzed. The Lindhard model parametrized by a single variable k which characterizes the quenching function was used. Limits at 90% confidence level are derived on the ratio ρ relative to standard model (SM) cross section of ρ<4.7 at the predicted value of k=0.162, while k<0.285 at the SM-value of ρ=1. Prospects on future positive measurements are discussed.

description: Quantum optics promises excellent capabilities for experimental demonstrations of quantum information processing. So far, the practical implementation of protocols displaying a clear quantum advantage has been limited, as they rely on perfect quantum states and high delity measurements. Additionally, the fragile nature of the quantum states makes them susceptible to imperfections in measurement devices, and environmental loss. Two of the key challenges for quantum technologies are that of producing single photons, and pairs of entangled photons, more eciently, and overcoming the detrimental effects of photon loss. The research presented in this thesis tackles the practical realisation of quantum-enhanced protocols by improving spontaneous parametric down conversion for producing photon pairs. I present a spontaneous parametric down-conversion source of frequency-uncorrelated polarisation-entangled photon pairs at telecom wavelengths. The source provides photon pairs that display-simultaneously-the key properties for high-performance quantum information tasks and the investigation of fundamental quantum physics. Specifically, the source provides high heralding efficiency, high quantum state purity and high entangled-state fidelity at the same time. Among the different tests applied, perfect non-classical interference between photons from independent sources with a visibility of (1005)% was observed. Additionally, the polarisation-unentangled version of the source achieved symmetric heralding efficiencies of up to (82 2)%. The following two experiments presented in this thesis make use of these high-performance sources to implement an entanglement verication protocol over a high-loss quantum channel, and to perform a quantum metrology experiment, both of which were not previously achievable with existing sources or designs.

description: Given a finite group G and a G-space X, we show that a direct sum $F_G (X) = \bigoplus_{n \geq 0}K_{G_n} (X^n) \bigotimes \C$ admits a natural graded Hopf algebra and $λ$-ring structure, where $G_n$ denotes the wreath product $G \sim S_n$. $F_G (X)$ is shown to be isomorphic to a certain supersymmetric product in terms of $K_G(X)\bigotimes \C$ as a graded algebra. We further prove that $F_G (X)$ is isomorphic to the Fock space of an infinite dimensional Heisenberg (super)algebra. As one of several applications, we compute the orbifold Euler characteristic $e(X^n, G_n)$.

description: The genome of eukaryotes is packaged into the small volume of the nucleus in an organised manner. This structure of DNA and associated proteins is called chromatin. The basic unit of chromatin is the nucleosome; an octomer of core histone proteins and associated DNA. Other proteins such as linker histones can also associate with the DNA or the core histones. The modular structure of chromatin allows for structural variation with functional consequences including activation or repression of transcription. Alterations can include post-translational modifications to histones, remodelling by multi-protein complexes, DNA methylation, and non-allelic variants of the canonical histones. Changes to chromatin structure have an important impact on all DNA processing events. This thesis investigated the histone variant H2A.Z, a variant of the canonical core histone H2A. H2A.Z is highly conserved and essential in a number of species suggesting it has a critical function. Preliminary work using the Xenopus laevis developmental model system had revealed that disruption of H2A.Z function resulted in defective embryo morphology consistent with disrupted gastrulation and mesoderm development (Ridgway et al., 2004a). This led to the following hypothesis: H2A.Z is important to gastrulation and mesodermal development in X laevis because it plays a developmental role. Temporal and spatial expression patterns of H2A.Z mRNA demonstrated in this study are consistent with a role in mesoderm development. Peak H2A.Z mRNA expression levels occur during gastrulation. H2A.Z mRNA is enriched in the marginal zone of the late blastula, involuting tissue in the gastrula and in notochord (a mesodermal tissue) in tailbud embryos. Significantly, maternal H2A.Z mRNA is enriched asymmetrically in dorsal cells of the early blastula before zygotic transcription, indicating that H2A.Z may play a role in determining polarity of the dorsal ventral axis. Two important processes for development were examined in this thesis: cell fate and cell movement. Determination of mRNA levels and localisations for a selection of mesodermal marker genes indicates that cell fate programs progress normally in embryos where H2A.Z function is disrupted. However, the localisation of mesoderm derived cells is perturbed suggesting cell movement is perturbed. Taken together these studies suggest the H2A.Z histone variant has a specific role in regulating cell mobility during early Xenopus laevis development.

description: For over 25 years it is known that the roll structure of electroconvection (EC) in the dielectric regime in planarly aligned nematic liquid crystals has, after a transition to defect chaos, the tendency to form chevron structures. We show, with the help of a coarse-grained model, that this effect can generally be expected for systems with spontaneously broken isotropy, that is lifted by a small external perturbation. The linearized model as well as a nonlinear extension are compared to simulations of a system of coupled amplitude equations which generate chevrons out of defect chaos. The mechanism of chevron formation is similar to the development of Turing patterns in reaction diffusion systems.

T cell deficiencies resulting from aberrant pre-mRNA alternative splicing caused by a novel splicing silencer hnRNP LL in an ENU mutant mouse strain thunder

Subjects: ENU mutagenesis, pre-mRNA, alternative splicing, T cell, immunity, hnRNP LL.

description: ENU mutagenesis screening is a phenotype-driven approach to identify genes in a nonbiased manner. Through this approach we identified a previously uncharacterised gene, Hnrpll, which is involved in nascent mRNA alternative splicing. Thunder strain carries a point mutation in the Hnrpll gene (407T->A) in its first RNA recognition motif (RRM) which changes it function in regulating nascent mRNA alternative splicing. One of Hnrpll target genes is CD45 that undergoes alternative splicing in T cells depending on their development stages and activation status. We demonstrated that Hnrpllthu/thu T cells fail to silence 3 variable exons of CD45 and result in constitutive expression of CD45RA, B, and C epitopes on the cell surface. Retroviral based expression of wild-type Hnrpll cDNA in the Hnrpllthu/thu T cells compensates the effects of loss of function in the mutation. The mutated RRM1 domain remains the ability to bind the regulatory element of activation responsive sequence (ARS) within CD45 pre-mRNA but cripples the protein function by destabilising the proteins to unfold in a thermolible sensitive manner. We also found that Hnrpllthu/thu mutation disrupts peripheral T cell subsets. Thunder mice have normal T cell development in the thymus but specifically lost naïve T cells in the peripheral lymphoid tissues, whereas memory T cells are not affected. Hnrpllthu/thu naïve T cells can homeostatically proliferate but fail to persist for a long term in vivo, suggesting that thunder mutation influences naïve T cell longevity. We observed that Hnrpllthu/thu naïve T cells express lower level of IL-7Ra and lower Bcl-2, together with the stronger pro-apoptotic BimS isoform due to alternative splicing. This highlights the nonredundant role of the Hnrpll gene in regulating peripheral T cell homeostasis. CD45 isoforms are widely used markers to distinguish naïve and memory T cell subsets. CD45 splicing does not account for the loss of naïve T cells in the thunder mice, however, CD45RABC shows stronger phosphatase activity than CD45RO when the amount of CD45 is dramatically reduced to 5% remaining on T cell surface, suggesting jointly regulation of CD45 catalytic activity by its expression and alternative splicing. Immunological memory is the hallmark of the adaptive immune system. Through Affymetrix mouse all exon arrays, we found that hnRNP LL protein plays a critical role in controlling an extensive program of alternative splicing as naïve T cells differentiate to the memory cell fate. It acts as an either trans- or cis- acting factor in regulating multiple nascent mRNA alternative splicing. This study provides an unprecedented insight into the extent of alternative splicing in the generation of immune memory.

description: Bit-flip attacks (BFAs) can manipulate deep neural networks (DNNs). For high-level DNN models running on deep learning (DL) frameworks like PyTorch, extensive BFAs have been used to flip bits in model weights and shown effective. Defenses have also been proposed to guard model weights. However, DNNs are increasingly compiled into DNN executables by DL compilers to leverage hardware primitives. These executables manifest distinct computation paradigms; existing research fails to accurately capture and expose the BFA surfaces on DNN executables.
 To this end, we launch the first systematic study of BFAs on DNN executables. Prior BFAs are limited to attacking model weights and assume a strong whitebox attacker with full knowledge of victim model weights, which is unrealistic as weights are often confidential. In contrast, we find that BFAs on DNN executables can achieve high effectiveness by exploiting the model structure (usually stored in the executable code), which only requires knowing the (often public) model structure. Importantly, such structure-based BFAs are pervasive, transferable, and more severe in DNN executables. They also slip past existing defenses.
 To demonstrate the new attack surfaces, we assume a weak and more realistic attacker with no knowledge of victim model weights. We design an automated tool to identify vulnerable bits in victim executables with high confidence (70% vs. baseline 2%). We show on DDR4 DRAM that only 1.4 flips on average are needed to fully downgrade the accuracy of victim models, including quantized ones which could require 23x more flips previously, to random guesses. We comprehensively evaluate 16 DNN executables, covering large-scale models trained on commonly-used datasets compiled by the two most popular DL compilers. Our finding calls for incorporating security mechanisms in future DNN compilation toolchains.

description: The features for the unsteady process of thermal equilibration ("the fast motions") in a one-dimensional harmonic crystal lying in a viscous environment (e.g., a gas) are under investigation. It is assumed that initially the displacements of all the particles are zero and the particle velocities are random quantities with zero mean and a constant variance, thus, the system is far away from the thermal equilibrium. It is known that in the framework of the corresponding conservative problem the kinetic and potential energies oscillate and approach the equilibrium value that equals a half of the initial value of the kinetic energy. We show that the presence of the external damping qualitatively changes the features of this process. The unsteady process generally has two stages. At the first stage oscillations of kinetic and potential energies with decreasing amplitude, subjected to exponential decay, can be observed (this stage exists only in the underdamped case). At the second stage (which always exists), the oscillations vanish, and the energies are subjected to a power decay. The large-time asymptotics for the energy is proportional to $t^{-3/2}$ in the case of the potential energy and to $t^{-5/2}$ in the case the kinetic energy. Hence, at large values of time the total energy of the crystal is mostly the potential energy. The obtained analytic results are verified by independent numerical calculations.

description: The relation between the dynamical properties of a coupled quasiparticle-oscillator system in the mixed quantum-classical and fully quantized descriptions is investigated. The system is considered to serve as a model system for applying a stepwise quantization. Features of the nonlinear dynamics of the mixed description such as the presence of a separatrix structure or regular and chaotic motion are shown to be reflected in the evolution of the quantum state vector of the fully quantized system. In particular it is demonstrated how wave packets propagate along the separatrix structure of the mixed description and that chaotic dynamics leads to a strongly entangled quantum state vector. Special emphasis is given to view the system from a dynamical Born-Oppenheimer approximation defining integrable reference oscillators and elucidating the role of the nonadiabatic couplings which complements this approximation into a rigorous quantization scheme.

description: Wireless sensor networks for sports monitoring applications support data collection from multiple sensor platforms. Important network requirements are data throughput, range, low power operation and number of sensor nodes. The Bluetooth specification has been designed for low power, medium data rate, cable replacement solutions and as such is useful for wireless sensor networks. However it has a limitation of a maximum number of eight active devices per Bluetooth network (Piconet). This project investigates and extends the capability of the Bluetooth specification and increases the usefulness for sensor applications. This has been achieved by utilising a combination of a network of Bluetooth wireless access points and innovative Bluetooth network structures. The Bluetooth network structures were created and controlled via the fixed Bluetooth access points, which act as root nodes for the network structures. The developed network structures for wireless sensing applications were Piconet Sharing, Scatternet Tree, Piconet Tree and Multiple Piconet. These network structures all allow more than seven Bluetooth devices to communicate to a fixed Bluetooth access point. A MATLAB based simulation tool was developed to compare the theoretical throughput per node for each network structure and validated experimentally. Bluetooth hardware was used to test the performance of the proposed network structures with current Bluetooth hardware and software implementations. Several limitations were discovered with the test Bluetooth hardware used and this impacted on the performance of the Bluetooth network structures. All network structures were shown (via data extrapolation) to provide the throughput per node required for the specific wireless sensing application. The developed network of Bluetooth root nodes combined with the developed network structures provided a complete solution suitable for wireless sensor applications. The same principles developed for Bluetooth based wireless sensor networks can be applied to other wireless applications that require a greater number of nodes than standard Bluetooth Piconets can provide. The developed network structures expand the applications that the Bluetooth Specification is suitable for.

description: This thesis focuses on the implementation of participatory development between 1978 and 1993 in the Pesantren Annuqayah of Madura and the Pesantren Maslakul Huda of Central Java during which they collaborated with LP3ES (Lembaga Penelitian, Pendidikan, dan Penerangan Ekonomi dan Sosial, the Institute for Social and Economic Research, Education and Information) and P3M (Perhimpunan Pengembangan Pesantren and Masyarakat, the Indonesian Society for Pesantren and Community Development). This study examines the effectiveness of the pesantren in accommodating bottom-up development as an alternative to the top-down development model of the New Order government. This study demonstrates that while both pesantren strengthened local people to participate more fully in their own development, in both cases the pesantren utilised participatory development to maintain their dominance over local society.

description: In this paper we complete in several aspects the picture of locally compact quantum groups. First of all we give a definition of a locally compact quantum group in the von Neumann algebraic setting and show how to deduce from it a C*-algebraic quantum group. Further we prove several results about locally compact quantum groups which are important for applications, but were not yet settled in our paper "Locally compact quantum groups". We prove a serious strengthening of the left invariance of the Haar weight, and we give several formulas connecting the locally compact quantum group with its dual. Loosely speaking we show how the antipode of the locally compact quantum group determines the modular group and modular conjugation of the dual locally compact quantum group.

description: Recent detections of aromatic species in dark molecular clouds suggest formation pathways may be efficient at very low temperatures and pressures, yet current astrochemical models are unable to account for their derived abundances, which can often deviate from model predictions by several orders of magnitude. The propargyl radical, a highly abundant species in the dark molecular cloud TMC- 1, is an important aromatic precursor in combustion flames and possibly interstellar environments. We performed astrochemical modeling of TMC-1 using the three-phase gas-grain code NAUTILUS and an updated chemical network, focused on refining the chemistry of the propargyl radical and related species. The abundance of the propargyl radical has been increased by half an order of magnitude compared to the previous GOTHAM network. This brings it closer in line with observations, but it remains underestimated by two orders of magnitude compared to its observed value. Predicted abundances for the chemically related C4H3N isomers within an order of magnitude of observed values corroborate the high efficiency of CN addition to closed-shell hydrocarbons under dark molecular cloud conditions. The results of our modeling provide insight into the chemical processes of the propargyl radical in dark molecular clouds and highlight the importance of resonance-stabilized radicals in PAH formation.

description: The exceptional abilities of top-tier athletes – from Simone Biles’ dizzying gymnastics to LeBron James’ gravity-defying bounds – can easily lead one to forget to marvel at the exceptional breadth of everyday movements. Whether holding a cup of coffee, reaching out to grab a falling object, or cycling at a quick clip, every motor action requires activating multiple muscles with the appropriate intensity and timing to move each limb or counteract the weight of an object. These actions are planned and executed by the motor cortex, which transmits its intentions to motoneurons in the spinal cord, which ultimately drive muscle contractions. A central problem in neuroscience is precisely how neural activity in cortex and the spinal cord gives rise to this diverse range of behaviors. At the level of spinal cord, this problem is considered to be well understood. A foundational tenet in motor control asserts that motoneurons are controlled by a single input to which they respond in a reliable and predictable manner to drive muscle activity, akin to the way that depressing a gas pedal by the same degree accelerates a car to a predictable speed. Theories of how motor cortex flexibly generates different behaviors are less firmly developed, but the available evidence indicates that cortical neurons are coordinated in a similarly simplistic, well-preserved manner. Yet a potential complication for both these old and new theories are the relative paucity of diverse behaviors during which motor cortex and spinal motoneurons have been studied. In this dissertation, I present results from studying these two neuronal populations during a broader range of behaviors than previously considered. These results indicate, in essence, that diverse behaviors involve greater complexity and flexibility in cortical and spinal neural activity than indicated by current theories.
Theory and empirics of root causes of economic progress

description: The thesis revisits the debate over the relative contribution of root causes (institutions, geography, trade openness, religion and culture, and knowledge) in economic growth. The results show that institutions, market proximity, malaria and Catholicism have direct effects on economic progress. Catholicism is associated with poor institutions and is not good for trade. Malaria is the most important factor for Africa. The Africa result is explained by an overlapping generations model which shows that high malaria incidence encourages households to consume more at the current period and save less for the future which leads to a poverty trap. Among institutions, ‘market creating institutions’ and ‘market stabilising institutions’ are important. Strong ‘market creating institutions’ characterized by the adequate protection of private property and contract enforcement are growth enhancing. ‘Market stabilizing institutions’ that ensures macroeconomic stability and does not undertake distortionary policies boosts investor confidence and are also good for growth. I notice that there is a growth maximizing level of ‘market regulation’ beyond which it increases red tape and kills the incentive for investment. The effect of ‘market legitimizing institutions’ is statistically insignificant.

description: Convolutional Neural Networks (ConvNets) are commonly developed at a fixed resource budget, and then scaled up for better accuracy if more resources are available. In this paper, we systematically study model scaling and identify that carefully balancing network depth, width, and resolution can lead to better performance. Based on this observation, we propose a new scaling method that uniformly scales all dimensions of depth/width/resolution using a simple yet highly effective compound coefficient. We demonstrate the effectiveness of this method on scaling up MobileNets and ResNet. To go even further, we use neural architecture search to design a new baseline network and scale it up to obtain a family of models, called EfficientNets, which achieve much better accuracy and efficiency than previous ConvNets. In particular, our EfficientNet-B7 achieves state-of-the-art 84.3% top-1 accuracy on ImageNet, while being 8.4x smaller and 6.1x faster on inference than the best existing ConvNet. Our EfficientNets also transfer well and achieve state-of-the-art accuracy on CIFAR-100 (91.7%), Flowers (98.8%), and 3 other transfer learning datasets, with an order of magnitude fewer parameters.

description: As a consequence of the structural changes in agriculture many fields were let rest in the past years and decades. This is a particular phenomenon in the New Laender. The present paper deals with fallow land on the "Kleiner Fallstein" in the northern foreland of the Harz (Saxony-Anhalt). The species migration patterns after five years rest is shown here by means of species lists, linear transects and a grid map. The question was which species are able to migrate into fallow land during five years and how far is the distance. The fallow land was chosen after the following criteria: areas directly above calcareous grassland, directly below calcareous grassland, and areas separated from calcareous grassland by broad shrubbery. Most prominent were Festuco-Brometea and Koelerio-Corynephoretea (Sedo-Scleranthetea) species as well as biennial species such as Echium vulgare and Cynoglossum officinale. Species with a high potential of dissemination such as Festuca rupicola migrated up to 204 meters, while Alyssum alyssoides and Bromus erectus were only found in the first 10 meters of the fallow land. 160 species were found in the fallow land but just one rare species (Asperula cynanchica). 21 Festuco-Brometea species und 15 Koelerio-Corynephoretea species migrated into fallow land. There is evidence that at least young fallow land may be a suitable habitat for these species. Many of the species are able to spread by stolones. The number of species migrated into the fallow land depends on the position of the fallow land relatively to the calcareous grassland. The highest number of Festuco-Brometea and Koelerio-Corynephoretea species migrated into fallow land below calcareous grassland, whereas less species migrated into fallow land above calcareous grassland. Broad shrubbery separating fallow land from calcareous grassland seems to delay the migration of Festuco-Brometea and Koelerio-Corynephoretea species into fallow land.
