L'analisi delle pasioni: note a «La Regenta» di Clarín
Creators: name: Rosso, Maria
Publisher: name: Università degli Studi di Milano
Year: 2011

description: «La Regenta» es el fruto de las reflexiones teóricas de Clarín sobre el naturalismo, en las que el escritor reconoce un único dogma: «copiar la vida» en sus complejas relaciones humanas y sociales. Movido por el propósito de presentar un «cuadro general» de la realidad, en su novela compone un amplio retablo y analiza las pasiones de los personajes en sus recíprocas presiones conflictivas, que llevan a una implacable lucha por la autoafirmación, siguiendo un instinto primordial de conquistar, dominar y devorar. Entre las estrategias compositivas del autor, adquiere una particular eficacia la focalización múltiple, que utiliza las miradas de los personajes como importante instrumento narrativo y, al mismo tiempo, las convierte en un motivo esencial de la acción. Destaca, además, el arte del retrato, que explota las convenciones codificadas de la fisiognómica, integrándolas con una gestualidad comunicativa, en la que puede vislumbrarse la influencia de «La expresión de las emociones» de Darwin.

description: We study the effect of cooling on the spatial distribution of the topological charge density in quenched SU(2) lattice gauge theory with overlap fermions. We show that as the gauge field configurations are cooled, the Hausdorff dimension of regions where the topological charge is localized gradually changes from d = 2..3 towards the total space dimension. Therefore, the cooling procedure destroys some of the essential properties of the topological charge distribution.

description: With software increasing in scale and playing an important role in today’s society, application reliability has become a crucial metric. Most applications use logging as a mechanism to diagnose anomalies, but is often employed post-failure. However, since logs provide insight into current software health, they can be leveraged to detect anomalies, which could help with reducing system downtime. Anomaly detection using software execution logs has been explored in several prior studies, using both classical and deep neural network based machine learning models. In recent years, the research has largely focused in using variations of sequence-based deep neural networks (e.g., Long-Short Term Memory and Transformer-based models) for log-based anomaly detection on open-source data. However, they have not been applied in industrial datasets as often. In addition, the studied open-source datasets are typically very large in size with logging statements that do not change over time, which may not be the case with a dataset from an industrial service that is relatively new. In this thesis, we evaluate several state-of-the-art anomaly detection models on an industrial dataset from our research partner, which is much smaller and loosely structured than most open-source datasets. Results show that while all models are capable of detecting anomalies, certain models are better suited for less-structured datasets. We also see that model effectiveness changes when data leaks associated with a random train-test split is removed. A qualitative study of error types identified by the developers on the industrial dataset further shows strengths and weaknesses of the models in detecting different types of anomalies. Finally, we explore the effect of limited training data by gradually increasing the training set size, to evaluate if the model effectiveness does depend on the training set size.

description: En la segunda mitad del siglo XIX la poesía española se encuentra en un momento de transición que se refleja en los prólogos de los volúmenes poéticos. Dos autores formados en el ambiente de la Escuela de Sevilla, Cañete y Campillo, expresan sus ideas sobre la poesía escribiendo prefacios para los jóvenes poetas, e intentan renovar la estética poética por medio de la asimilación de los ejemplos alemanes y la sugestión de la poesía popular. Por un lado, Cañete se da cuenta de la necesidad de una evolución de la poesía y alaba la brevedad y la sencillez de las composiciones modernas; Campillo, en cambio, sigue rechazando la evolución hacia el intimismo e intenta defender el patrimonio clásico de la escuela sevillana.

description: Software testing is an important part of the software development cycle. It helps prevent future potential defects in the system and reduce maintenance cost. However, it is often neglected by developers like other tasks such as documentation, code review, etc. Automated unit test generation is the process of generating unit tests for a method or a class for a given project. It helps developers to detect some of the potential defects automatically. Existing approaches usually use heuristic methods such as random data generation (fuzzing) or genetic algorithms (search-based testing) to generate tests, which are based on optimizing a cost function such as code coverage. Some of the main downsides of these methods are (a) the synthetic nature of the tests that are generated based on predefined templates and (b) targeting surrogate measures such as coverage, which might not always detect existing defects. In this study, we leverage novel machine translation models, i.e., transformers to generate unit tests for a given program. Specifically, we use CodeT5, i.e., a state-of-the-art large code model, and fine-tune it on the test generation downstream task. We use the Methods2test dataset for fine-tuning CodeT5. We also use Defects4j for project-level domain adaptation and evaluation. The main contribution of this study is proposing a fully automated testing framework that leverages developer-written tests and available code models to generate compilable unit tests. Results show that using domain adaptation, we can increase line coverage of the model-generated unit tests by 49.9% and 54% in terms of mean and median (compared to the model without domain adaptation). We can also use our framework as a complementary solution alongside common search-based methods to increase the overall coverage with mean and median of 25.3% and 6.3%. It can also increase the mutation score of search-based methods with mean and median of 8.6% and 1%.

description: En tres siglos de colonización, las relaciones culturales entre España y Filipinas fueron escasas. Varios factores contribuyeron a popularizar lo filipino en la Península a partir de la segunda mitad del siglo XIX. A esta época pertenecen los textos de Cañamaque y de Entrala, en abierta polémica el uno con el otro, que expresan posturas diferentes acerca del fenómeno colonial, así como percepciones opuestas con respecto a los filipinos y a la sociedad española de Manila. Después de 1898, los vínculos afectivos entre la ex madre patria y la antigua colonia no cesaron, como demuestra Julio Palacios, que vierte en su libro —también objeto de análisis— el orgullo de constatar la presencia de una importante y positiva herencia española en el archipiélago.

description: Cloud manufacturing is seen as a promising improvement for networked manufacturing, with potential for achieving higher service quality at a lower cost, although the progress of its application has not met expectations. The main obstacle hindering its adoption is the reluctance of potential users to share data with cloud manufacturing due to concerns about data safety issues caused by central management. To address this drawback, the integration of a decentralized blockchain system has been proposed as a promising solution. However, the traceable data and provable system features of blockchain technology cannot guarantee data security, particularly for small or moving objects that lack the ability for data verification. Therefore, blockchain-based cloud manufacturing systems must have the ability to ensure data reliability. Moreover, the scalability problem must be addressed for the adoption of a blockchain-based system. This PhD thesis proposes a feasible architecture for a blockchain-based cloud manufacturing system and evaluates the reliability of perceived data through data similarity measurement. Firstly, the architecture of the system is outlined, with the use of rollup technology to address scalability issues. Second, the proper fee setting for the system is analyzed. For data similarity measurement, comparable data is selected using a modified clustering algorithm, and the data is described using polygon-based descriptions, including existing and proposed polygon descriptions. Finally, data similarity measurement is transformed into a similarity comparison of polygon descriptions, with methods such as multi-objective programming-based similarity comparison and overlap area-based similarity comparison applied for this purpose. The feasibility of the proposed methods is verified through a case study.
PLA-BASED MULTILAYER PACKAGING FILMS

description: Abstract: Single-layer packaging films are sporadic on the market today, especially ones made of a single polymer. It is usually a blend of polymers or some polymer-based composite material. This is because one material does not have all the required properties for food protection, and the purpose of functionality causes the need for combining and blending materials. Today's packaging materials are multilayer structures since they provide the best quality and safety of the packed food maintenance. Multilayer packaging materials are tough to recycle because it is complicated to separate layers made from different materials, and there is no unique way to do it for all materials. For this reason, multilayer films are the leading variety of packaging waste in landfills. Due to the increased production and application of single-use plastics, the EU adopted a range of strategies and regulations to minimize plastic waste and incorporate plastic into the circular economy. The main goal is to change the product design and enable the recycling of all plastic packaging by 2030. PLA-based multilayer films were prepared in this work by combining solvent casting PLA films with electrospun PLA film. Two and three-layer structures were prepared by annealing the layers to achieve transparent films. The electrospun layer is to ensure better barrier properties compared to solvent cast film. Mechanical, thermal, morphological, and surface properties were examined together with water vapor permeability for all samples. The presence of the electrospun layer did not affect the mechanical and thermal properties compared to pure PLA films, while it has some positive effects on barrier properties. Combining polymer processing technologies without combining materials can be an excellent way to reach sustainability goals in the forthcoming years.

description: We consider a population of agents that are heterogeneous with respect to (i) their strategy when interacting $n_{g}$ times with other agents in an iterated prisoners dilemma game, (ii) their spatial location on $K$ different islands. After each generation, agents adopt strategies proportional to their average payoff received. Assuming a mix of two cooperating and two defecting strategies, we first investigate for isolated islands the conditions for an exclusive domination of each of these strategies and their possible coexistence. This allows to define a threshold frequency for cooperation that, dependent on $n_{g}$ and the initial mix of strategies, describes the outbreak of cooperation in the absense of migration. We then allow migration of a fixed fraction of the population after each generation. Assuming a worst case scenario where all islands are occupied by defecting strategies, whereas only one island is occupied by cooperators at the threshold frequency, we determine the optimal migration rate that allows the outbreak of cooperation on \emph{all} islands. We further find that the threshold frequency divided by the number of islands, i.e. the relative effort for invading defecting islands with cooperators decreeses with the number of islands. We also show that there is only a small bandwidth of migration rates, to allow the outbreak of cooperation. Larger migration rates destroy cooperation.

Low-Overhead Packet Loss Diagnosis for Virtual Private Clouds using P4-Programmable NICs

description: The virtual private cloud, a logical division into tenants of a service provider's multi-tenant multi-cloud architecture, has become a major trend in the cloud computing industry because of its cost-effectiveness. Effective monitoring systems are critical for cloud tenants to identify and troubleshoot problems that cause negative impact on the reliability and availability of their services in the virtualized cloud infrastructure. However, the virtualized and complex nature of cloud infrastructure limits tenants' ability to pinpoint problems that result in performance degradation, such as packet loss, within the cloud environment. Current monitoring systems are either designed for the physical network or are not adequate to be able to detect the specific cause of packet losses in the physical network. Besides, there are few virtual network monitoring systems suitable for tenants that impose an insignificant overhead. This thesis presents a Packet Loss Diagnosis (PLD) system, which is a specific monitoring service designed to detect packet losses on virtual networks. It notifies virtual private cloud tenants with diagnostic information for troubleshooting. This comprehensive mechanism is based on the modern capabilities of P4 data plane programmable NICs and has a limited footprint in the network. Virtual networks at cloud-scale pose considerable challenges in achieving this goal. We differentiate between packet losses in virtual and physical networks to address these challenges. As for the former, we support tenants with comprehensive information that allows them to locate and resolve their problems on their own. In relation to the latter, we provide high-level information respecting service isolation and abstraction. Furthermore, PLD is designed to meet the requirements of a monitoring system designed for multi-tenant clouds at large scales. To prove the viability of the proposed scheme, we implemented it in P4 as well as investigated its performance through extensive experiments and Mininet simulation. The results of our study demonstrate that the proposed scheme can detect all packet losses reliably and can notify tenants in real-time of the occurrence of packet losses while imposing a minimal overhead that is proportional to the number of packet losses.

The Role of Nuclear Envelope Lipids in Nuclear Shape and Transcription

Subjects: subject: biochemistry

subject: lipids
subject: genome organization
subject: Biology--Molecular

description: The nuclear envelope (NE) is a double membrane structure contiguous with the endoplasmic reticulum (ER) encompassing the nucleus. The NE is important in maintaining genome organization, as silenced domains are sequestered at the nuclear periphery, while active domains associate with the nuclear pore complex for rapid export of mRNA. Budding yeast in particular tether silenced telomeres at the NE to prevent aberrant recombination of the chromosome ends. In this thesis, the role of lipids in communication between the NE and telomere regulation was investigated, including how changes in lipid composition impact gene expression and overall nuclear architecture. Yeast cells were treated with the non-metabolizable lysophosphatidylcholine analog edelfosine, a lipid drug known to accumulate at the perinuclear ER. Edelfosine induced NE deformation and disrupted telomere clustering but not anchoring. In addition, the association of Sir4 of the Silent Information Regulator complex with telomeres decreased. RNA-seq analysis showed upregulation of Sir-dependent genes located at sub-telomeric regions, and downregulation of ribosomal protein genes. Transcriptomic analysis also revealed that two lipid metabolic circuits are activated in response to edelfosine, one mediated by the membrane sensing transcription factors, Spt23/Mga2, and the other by a transcriptional repressor, Opi1. Activation of these transcriptional programs resulted in higher levels of unsaturated fatty acids and the formation of nuclear lipid droplets. Interestingly, cells lacking Sir proteins displayed resistance to edelfosine and unsaturated fatty acids. Characterization of the edelfosine mechanism of toxicity in cells lacking SIR4 found that while these cells display similar NE deformations and formation of nuclear lipid droplets as seen in wild type cells, they have less internalization of sterols from the plasma membrane, with a concomitant maintenance of the proton pump Pma1 at the plasma membrane and a reduced acidification of the cytosol. Altogether this body of work presents evidence supporting a cross-talk between NE lipids and nuclear architecture and function.

title: DEPRECATED: Attachment and affect motivated eating behavior in an obese population: Maintenance versus relapse
Creators: name: Celec, Mary Jean
Publisher: name: University of Plymouth
Year: 1994

description: This dissertation explored object relations characteristics in an obese population by comparing those who relapse following treatment with those who maintain their weight losses following treatment. The impetus for this study came from the proliferation, in recent years, of weight loss programs whose long-term results have been dismal. This all-too-common trend of relapse only serves to perpetuate the negative physical and psychological concominants of obesity. This dissertation presented a psychodynamic approach to conceptualizing relapse in weight loss and conducted a preliminary exploration in an effort to glean same information to confirm or disconfirm the usefulness of this approach. Theoretically, disruptions in early attachment, through empathic failures on the part of the selfobject, interfere with internalization of self-soothing structures. consequently, when the self experiences intolerable affect, the self initiates some action to ameliorate it. In the case of obesity, the self eats compulsively. This dynamic plays a role in relapse. Assessing the theoretical concepts presented through the Bell Object Relations Inventory with particular attention to the Insecure Attachment subscale, this study proposed that those who relapsed would show greater object relations deficits than those who maintained their weight losses and that those who reported emotional eating would show greater deficits on the Insecure Attachment subscale than those who did not. The subjects included in this study were thirty-nine caucasian females who had participated in a modified fasting diet. The study contacted the subjects through mailed surveys. It analyzed the data collected through the use of a t-test. Results did not show a significant difference between the relapse and maintenance groups. However, a significant difference appeared on the Insecure Attachment subscale when it compared emotional eaters to non-emotional eaters. This finding was consistent with the theoretical link between affect motivated eating behavior and the quality of object relations.

Copper and nickel toxicity and metal loading capacity of larval haemolymph in Aedes aegypti, using a novel small volume laser ablation inductively coupled plasma mass spectrometry method
Creators: name: Kotzeva, Lilia Dimitrova
Publisher: name: University of British Columbia
Year: 2013

description: Much of the current literature focuses on fish as models for waterborne metal toxicology, yet few studies examine invertebrate or insect metal toxicology. The present study examined copper and nickel waterborne toxicity in Aedes aegypti larvae. The 24-hour LC₅₀ for copper in fouth instar larval Aedes aegypti was 2.28 mmol L-¹ (95% C. I. 1.97, 2.67) and 4.63 mmol L-¹ (95% C. I. 4.25, 5.05) in the unfed and fed treatments respectively. The 24-hour LC₅₀ for nickel in fouth instar larval Aedes aegypti was 17.2 mmol L-¹ (95% C. I. 15.58, 18.66) and 27.2 mmol L-¹¹ 1 (95% C. I. 25.49, 29.11) in the unfed and fed treatments respectively. To determine the metal loading capacity of haemolymph following acute and chronic copper and nickel exposures, a novel laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was developed as an alternative approach to analysis of small-volume samples. Matrix matching of liquid samples and standards was achieved by using oiled TLC plates. Sample chamber orientation was assessed, and the orientation used was opposite to the manufacturer’s specified orientation, resulting in better ablation characteristics. The relationship between the volume and surface area of samples spotted on the TLC plates was found to be linear. The method was validated using a certified reference material (Seronorm). It was determined that the average peak height of the chromatographs were best for analysis, after spatial profiling established the area of the most stable analyte signal. Further, the analytical method was independent of volume, avoiding the need to accurately measure small-volume samples. Using the developed method, it was found that Aedes aegypti larvae have an innate level of copper in their haemolymph and can concentrate copper in their haemolymph when chronically exposed to a low concentration (0.25 mmol L-¹ -1 mmol L-¹). Conversely, larvae did not concentrate nickel in their haemolymph, and nickel was not found in control samples of haemolymph. Taken together, the data supports copper’s role as an essential metal and implies that nickel may not be an essential metal for larval Aedes aegypti.

description: Unitary limit for model point scatterers in graphene is known to reveal low-energy resonances. The same limit could be achieved from hybridization of band electrons with the localized impurity level positioned in the vicinity of the Fermi level. The finite size defects represent an easier realization of the effective unitary limit, occurring when the Fermi wavelength induced by the potential becomes of the order of the size of the defect. We calculate the induced electron density and find two signatures of a strong impurity, independent of its specific realization. The dependence of the impurity-induced electron density on the distance changes near resonances from ~r^{-3} to ~r^{-2}. The total number of induced particles at the resonance is equal to one per degree of spin and valley degeneracy. The effects of doping on the induced density are found.

description: Legionella pneumophila is a Gram-negative bacterial pathogen that causes Legionnaires' disease, a severe form of pneumonia in humans. It utilizes a multiprotein complex called the Dot/Icm secretion system to translocate a diverse set of bacterial proteins known as effectors into host cells during infection. L. pneumophila's effector arsenal comprises over 330 proteins, accounting for more than 10% of this bacterium's proteome. The functional redundancy and sheer number of L. pneumophila effectors complicate the characterization of their specific functions during infection, which remains poorly understood. Recent research has revealed that Legionella bacteria have a unique mechanism of controlling the activity of other effectors by utilizing a subset of effectors called meta-effectors. These meta-effectors modify the function of other effectors by targeting them within the host cell. One such example is LubX, a meta-effector encoded by the lpg2830 gene in L. pneumophila, which targets another effector, SidH (encoded by lpg2829), for ubiquitination and degradation by host proteasome. A large-scale analysis of effector-meta-effector interactions has identified nineteen such pairs, indicating that this type of regulation plays a crucial role in Legionella's pathogenic strategy. This study investigates the functional diversification of SidH across different Legionella strains, its interaction with the meta-effector LubX, and its potential mechanisms underlying SidH-mediated toxicity. A combination of structural analysis, in vitro experiments, and in cellulo assays was employed to investigate the characteristics of the SidH protein. The study also evaluated the interactions between SidH and LubX and the toxicity of SidH orthologs across Legionella species using a yeast model system. The C-terminus portion of SidH adopts an alpha-helical fold with no structural similarity to other characterized proteins and co-precipitates with host Rab11A. The research findings also indicate that LubX specifically ubiquitinates the N-terminal region of SidH, and LubX mutants, which lack E3 ubiquitin ligase function, are incapable of ubiquitinating the N-terminal region of SidH. The results provide insights into the functional diversification of SidH and the species-specific mechanisms of effector-meta-effector interactions in bacterial pathogenesis, highlighting the importance of meta-effectors in the pathogenic strategy and emphasizing the need for both effector interaction and functional regulation.

description: We show that weak antilocalization by disorder competes with resonant Andreev reflection from a Majorana zero-mode to produce a zero-voltage conductance peak of order e^2/h in a superconducting nanowire. The phase conjugation needed for quantum interference to survive a disorder average is provided by particle-hole symmetry - in the absence of time-reversal symmetry and without requiring a topologically nontrivial phase. We identify methods to distinguish the Majorana resonance from the weak antilocalization effect.

Macro-scale direct shear device for studying the large displacement shear strength of soil-structure interfaces under very low effective normal stresses.

Publisher: name: University of British Columbia

description: This thesis describes a new macro-scale test device for assessing the large-displacement soil/solid interface shear strength at very low effective normal stresses (3 kPa to 6 kPa). The testing method arises from a need to obtain the interface friction between soils and epoxy-coated pipes under low effective normal stress levels which is an important consideration in the design of partly buried seabed pipelines. The test device is fundamentally similar to the conventional small-scale direct-shear apparatus except for its large footprint that provides a plan interface shear area of 1.72 m by 1.75 m. The device is designed to impart displacement-controlled interface-shearing at displacement rates ranging from 0.0001 mm/s to 1 mm/s and with the ability to reach a maximum interface shear displacement of 1.2 m. The desired normal stress at the soil/solid interface is obtained using surcharge loads externally applied by means of bulk sand or water masses, or both in certain cases. The device is instrumented with pressure transducers mounted flush with the top surface of the solid test surface for the measurement of pore water pressure at the shear interface, in turn, allowing accurate determination of the effective normal stress at the soil/solid interface during shearing. The key features of this device are described, and the device capabilities are demonstrated by testing three soil types (Fraser-River sand, non-plastic silt, kaolinite) on two test surfaces (mild steel, epoxy-coated mild steel) at effective normal stresses between 3 kPa and 7 kPa. Comparison of the test results with available findings from other devices is used to further confirm the suitability of the device for the intended purpose.

description: We use autocorrelation to investigate evolution in flow fields inferred by applying Fourier Local Correlation Tracking (FLCT) to a sequence of high-resolution (0.3 \arcsec), high-cadence ($\simeq 2$ min) line-of-sight magnetograms of NOAA active region (AR) 10930 recorded by the Narrowband Filter Imager (NFI) of the Solar Optical Telescope (SOT) aboard the {\em Hinode} satellite over 12--13 December 2006. To baseline the timescales of flow evolution, we also autocorrelated the magnetograms, at several spatial binnings, to characterize the lifetimes of active region magnetic structures versus spatial scale. Autocorrelation of flow maps can be used to optimize tracking parameters, to understand tracking algorithms' susceptibility to noise, and to estimate flow lifetimes. Tracking parameters varied include: time interval $Δt$ between magnetogram pairs tracked, spatial binning applied to the magnetograms, and windowing parameter $σ$ used in FLCT. Flow structures vary over a range of spatial and temporal scales (including unresolved scales), so tracked flows represent a local average of the flow over a particular range of space and time. We define flow lifetime to be the flow decorrelation time, $τ$. For $Δt > τ$, tracking results represent the average velocity over one or more flow lifetimes. We analyze lifetimes of flow components, divergences, and curls as functions of magnetic field strength and spatial scale. We find a significant trend of increasing lifetimes of flow components, divergences, and curls with field strength, consistent with Lorentz forces partially governing flows in the active photosphere, as well as strong trends of increasing flow lifetime and decreasing magnitudes with increases in both spatial scale and $Δt$.
