Mourning, materiality and the feminine: Sarah Pucill’s films 2004-2010
Creators: name: Pucill, Sarah
Publisher: name: University of Westminster
Year: 2014

description: The writing-up of this PhD has examined experimental films I made between 2004 and 2010, in all five 16mm films: Stages Of Mourning, (17min, 2004), Taking My Skin, (35min, 2006), Blind Light (21min, 2007), Fall In Frame (19min, 2009), Phantom Rhapsody (19min, 2010). As I have been making films that have been exhibited and funded in the public field since 1990, the films included here constitute just less than half of my total films to date. The commentary is divided into three sections, each of which analyses the films from a particular perspective. In each section the five films are considered in turn, in chronological order. The rationale for having three different perspectives to analyse each film is that this provides a means of acknowledging and preserving a sense of the alterity of artists’ film, where readings are understood more as interpretations than as explanations. The choice of focus in each section summarises key considerations that have been relevant to my filmmaking practice over this time period, if not since the start of my filmmaking in 1990. In addition to providing contextual international film artists from both avantgarde and feminist film, I also reference theorists from philosophy to film and feminist studies who have been instrumental in the rationale for the films.
The first section explores the films from the point of view of cinematic space, examining factors such as camera frame, angle, lens and edit as well as qualities of lighting, and durational qualities where for example a slowing of time might expand an idea of the space. Cinematic space is as much expressed through sound, so where relevant this is also discussed. The second section focuses on qualities of texture through both image and sound. In particular, as all the films were shot and printed onto 16mm, the question of the haptic in relation to the films is discussed, as is the
low-budget hand-made texture of image and sound that is the materiality of the unpolished. Vivian Sobchack (The Address of the Eye: A Phenomenology of Film Experience, 1992), Sobchack (Inscribing Ethical Space: Ten Propositions on Death, Representation and Documentary, 1984) Laura U. Marks (The Skin of the Film: Intercultural Cinema, Embodiment, and the Senses, 2000) and Tom Gunning (The Cinema of Attraction: Early Film, Its Spectator and the Avant-Garde, 2006) are key texts I refer to. The third section focuses on issues of gender, in particular the female body, the female and lesbian gaze, and queer sexuality. Where the first two sections focus more on the structure and language or form of the films, this section focuses on social and philosophical questions of gender difference as points of critique or protest in the films. Luce Irigaray (Speculum Of The Other Woman, 1985 and This Sex Which Is not One, 1985) and Laura Mulvey (‘Visual Pleasure and Narrative Cinema’, 1975) are key texts that inform the writing.

description: Recent photometric observations of first-overtone classical Cepheids and RR Lyrae stars have led to the discovery of additional frequencies showing a characteristic period ratio of 0.60-0.65 with the main pulsation mode. In a promising model proposed by Dziembowski (2016), these signals are suggested to be due to the excitation of non-radial modes with degrees 7, 8 and 9 (Cepheids) or 8 and 9 (RR Lyrae). Such modes usually have low amplitudes in photometric data. Spectroscopic time series offer an unexplored and promising way forward. We simulated time series of synthetic line profiles for a representative first-overtone classical Cepheid model and added a low-amplitude non-radial mode. We studied sets of spectra with dense sampling and without noise, so-called 'perfect' cases, as well as more realistic samplings and signal-to-noise levels. Besides the first-overtone mode and the non-radial mode, also the harmonics of both modes and combination signals were often detected, but a sufficiently high sampling and signal-to-noise ratio prove essential. The amplitudes of the non-radial mode and its harmonic depend on the azimuthal order $m$. The inclination is also an important factor determining the detectability of the non-radial mode and/or its harmonic. We compared the results obtained for the predicted high degrees with those for lower-degree modes. Finally, we studied the sampling requirements for detecting the non-radial mode. Our findings can be used to plan a spectroscopic observing campaign tailored to uncover the nature of these mysterious modes.

description: Hadith is a mandatory thing to be studied and practiced by Muslims. There are many types of teachings that humans can take by studying the hadith. To assist Muslims in studying the hadith, a multi label classification system is needed to categorize Sahih Bukhari Hadi in Indonesian translation based on three topics, namely prohibition, advice and information. In building a text classification system, there are various classification methods that can be used, in this study using Random Forest (RF). The simplicity of the RF algorithm and good ability to deal with high dimensional data, make RF a suitable method of text classification. But, there is not widely known RF capability for the multi label classification. This study uses the Problem Transformation approach method, namely Binary Relevance (BR) and Label Powerset (LP) to adapt RF in building a multi label classification system. The results showed that the best hamming loss performance obtained from a system that used BR and does not use stemming which is equal to 0,0663. These results indicate that the BR method is better than the LP method in adapting the RF algorithm to perform multi label classification of hadith data. This is happened because the BR method produces a classification model of the number of labels in the hadith data and on the other hand, the transformation of data from the use of LP makes the data are imbalanced.

Patterns of practice of general surgeons in non-metropolitan British Columbia
Creators: name: Herdman, John
Publisher: name: University of British Columbia
Year: 2010

description: The problem of ensuring efficient use of human resources in the health care field has become of great importance with the complete coverage of the population by publicly funded schemes that has occured in recent years. There have been numerous suggestions for the replacement of physicians by less skilled personnel, and attention has also been paid to the problem of whether physicians practising in a free-enterprise, fee-for-service system make the most desirable use of their skills. This study examines the practices of two groups of British Columbia surgeons. It seeks to determine the size of their operative workloads, and considers factors which may influence the patterns of practice of these surgeons. The workloads are measured in California Relative Value units, using the British Columbia Medical Association fee schedule and Medical Services Commission data as the basis of a computer analysis. It was found that the workloads were at less than a desirable level as this has been defined in the literature, and that some of the general surgeons carry out a considerable amount of subspecialty surgery, and of general practice. The reasons for this are discussed with particular emphasis on the significance of these findings for medical manpower planning. Several possible areas of further research are described. It is believed that these would provide information which is necessary for sound decision making in the health care field.

description: The rise of beauty products in recent times can make consumers hesitate to choose a beauty product, especially for women. Beauty product reviews have become a very valuable source of information for consumers in making decisions to purchase a product in improving their products and marketing strategies. The process of sentiment analysis on negative and positive beauty product reviews will be classified one by one. Therefore, in this study, sentiment analysis was applied to the beauty product review data using the K-Nearest Neighbor (KNN) method to find the best k in the case of this study. The dataset used will be pre-processed with case folding, noise removal, tokenization, stemming, stopword removal, and slang words, for feature extraction using Term Frequency Inverse Document Frequency (TF-IDF) to calculate the weight of a word in the document, and The feature selection method uses Chi-Square which aims to select the features needed to increase the accuracy value. In this study, the best accuracy value was 71% of the data classified using KNN with a k value of 50 and the model on feature selection with 76 features.

description: We present evidence that the WASP-14 exoplanetary system has misaligned orbital and stellar-rotational axes, with an angle lambda = 33.1 +/- 7.4 deg between their sky projections. The evidence is based on spectroscopic observations of the Rossiter-McLaughlin effect as well as new photometric observations. WASP-14 is now the third system known to have a significant spin-orbit misalignment, and all three systems have "super-Jupiter" planets (M_P > 3 Mjup) and eccentric orbits. This finding suggests that the migration and subsequent orbital evolution of massive, eccentric exoplanets is somehow different from that of less massive close-in Jupiters, the majority of which have well-aligned orbits.

description: This work presents hybrid Constraint Programming (CP) and metaheuristic methods for the solution of Large Scale Optimization Problems; it aims at integrating concepts and mechanisms from the metaheuristic methods to a CP-based tree search environment in order to exploit the advantages of both approaches.

The modeling and solution of large scale combinatorial optimization problem is a topic which has arisen the interest of many researcherers in the Operations
Research field; combinatorial optimization problems are widely spread in everyday life and the need of solving difficult problems is more and more urgent.

Metaheuristic techniques have been developed in the last decades to effectively handle the approximate solution of combinatorial optimization problems; we will examine metaheuristics in detail, focusing on the common aspects of different techniques.
Each metaheuristic approach possesses its own peculiarities in designing and guiding the solution process; our work aims at recognizing components which can be extracted from metaheuristic methods and re-used in different contexts.
In particular we focus on the possibility of porting metaheuristic elements to constraint programming based environments, as constraint programming is able to deal with feasibility issues of optimization problems in a very effective manner.

Moreover, CP offers a general paradigm which allows to easily model any type of problem and solve it with a problem-independent framework, differently from
local search and metaheuristic methods which are highly problem specific.

In this work we describe the implementation of the Local Branching framework, originally developed for Mixed Integer Programming, in a CP-based environment. Constraint programming specific features are used to ease the search
process, still mantaining an absolute generality of the approach. We also propose a search strategy called Sliced Neighborhood Search, SNS, that iteratively explores slices of large neighborhoods of an incumbent solution by performing CP-based tree search and encloses concepts from metaheuristic techniques. SNS
can be used as a stand alone search strategy, but it can alternatively be embedded in existing strategies as intensification and diversification mechanism. In particular we show its integration within the CP-based local branching.
We provide an extensive experimental evaluation of the proposed approaches on instances of the Asymmetric Traveling Salesman Problem and of the Asymmetric Traveling Salesman Problem with Time Windows. The proposed approaches achieve good results on practical size problem, thus demonstrating the benefit of integrating metaheuristic concepts in CP-based frameworks.

Customer Oriented Ideation and its Impact on Customer Adoption of New Solutions
Creators: name: Lysenko, Daryna
Publisher: name: University of Westminster
Year: 2021

description: Customer adoption of new solutions is critical for the development of the modern business environment, and both academics and practitioners have been investigating this notion to uncover the customer adoption patterns to progress business and withstand competition. Despite the variety of marketing research techniques and practices commonly used to obtain customer data it has been said that the customers that “talk the talk” do not always “walk the walk” of innovation adoption. The challenge remains unchanged: making innovation accessible and easy to adopt in consumers’ everyday lives.

This thesis is looking into the processes of creating new solutions to identify the key drivers within the ideation processes that facilitate adoption. The research inquiry is supported by the tendencies in the industry, where, despite the increasing number of new technologies and approaches aimed to develop better products, the success-to-failure ratios remain quite low. The aim of the study is to design an integrative theoretical framework, explaining the drivers of ideation, the impact of customer orientation within ideation, and the influence it has on innovation adoption. 

The author used integrated methodology, combining the best practices of the deductive approach, commonly applied in conceptual works, and qualitative research methodology, where further insights were uncovered via interviews and a focus group. In this research project, the integrated methodology has been applied to combine the strengths of each of the research techniques and uncover insights into the complex notions and relationships under investigation. 

The findings include the introduction of COI and the three-dimensional model, facilitating the solutions development practice, aiming to help achieve a more sustainable growth within the service industries. The author has introduced a novel notion of Customer Oriented Ideation (COI) that focuses on the use of customer insights within the solutions development process and its impact on the market success. The author has also developed a questionnaire for further quantitative investigation of the framework, and further refined it via a pilot study.

description: The many platforms that are equipped with review features make it easy for people to convey anything. Product reviews are judgments that are opinions from consumers about the products they have purchased. These reviews can provide benefits for both producers and consumers. Reviews from consumers can contain ratings that cover aspects of the product and reviews can run into hundreds or even thousands. A large number of reviews makes it difficult in the sentiment analysis process. Therefore we need a model that can analyze sentiment based on aspects of the product. Sentiment analysis was performed using the naive Bayes algorithm, feature extraction with TF-IDF, and feature selection with chi-square. The application of stopwords removal or stemming processes reprocessing and the use of n-grams in feature extraction can affect the resulting performance. In addition, the application of feature selection to the built model has an important role because it can improve classification performance. From the research results obtained the best accuracy of 80,18%, recall of 72,49%, precision of 77,25%, and f1-score of 74,73%.

description: Needs for news information has increased since the change from physical media to online media. News is grouped according to categories to making it easier for readers to get the news as desired. Grouping to determine the category of news information is known as text classification. The number of words in the news text create diversity of words that appear and can be minimized by the stemming process, which is changing an affixed word into its root word. This study comparing between use of stemming and without stemming and finding the best value of K and optimum distance calculation of K-Nearest Neighbor. The best accuracy is 0.9671 which is obtained when stemming algorithm not applied, number of K=9 and cosine distance is used as distance metric. This result is greater than the classification that applies stemming algorithm in condition K=7 using cosine distance which resulted accuracy in 0.9660.

Generic Architecture for Predictive Computational Modelling with Application to Financial Data Analysis: Integration of Semantic Approach and Machine Learning
Creators: name: Yerashenia, Natalia
Publisher: name: University of Westminster
Year: 2023

description: The PhD thesis introduces a Generic Architecture for Predictive Computational Modelling capable of automating analytical conclusions regarding quantitative data structured as a data frame. The model involves heterogeneous data mining based on a semantic approach, graph-based methods (ontology, knowledge graphs, graph databases) and advanced machine learning methods. The main focus of my research is data pre-processing aimed at a more efficient selection of input features to the computational model.

Since the model I propose is generic, it can be applied for data mining of all quantitative datasets (containing two-dimensional, size-mutable, heterogeneous tabular data); however, it is best suitable for highly interconnected data.

To adapt this generic model to a specific use case, an Ontology as the formal conceptual representation for the relevant domain knowledge is needed.

I have determined to use financial/market data for my use cases. In the course of practical experiments, the effectiveness of the PCM model application for the UK companies’ financial risk analysis and the FTSE100 market index forecasting was evaluated. The tests confirmed that the PCM model has more accurate outcomes than stand-alone traditional machine learning methods.

By critically evaluating this architecture, I proved its validity and suggested directions for future research.
Wireless systems for the fourth generation

Subjects: ING-INF/03 Telecomunicazioni

description: Today, third generation networks are consolidated realities, and user expectations on new applications
and services are becoming higher and higher. Therefore, new systems and technologies
are necessary to move towards the market needs and the user requirements. This has driven the
development of fourth generation networks.
”Wireless network for the fourth generation” is the expression used to describe the next step
in wireless communications. There is no formal definition for what these fourth generation
networks are; however, we can say that the next generation networks will be based on the
coexistence of heterogeneous networks, on the integration with the existing radio access network
(e.g. GPRS, UMTS, WIFI, ...) and, in particular, on new emerging architectures that are obtaining
more and more relevance, as Wireless Ad Hoc and Sensor Networks (WASN). Thanks to their
characteristics, fourth generation wireless systems will be able to offer custom-made solutions and
applications personalized according to the user requirements; they will offer all types of services
at an affordable cost, and solutions characterized by flexibility, scalability and reconfigurability.
This PhD’s work has been focused on WASNs, autoconfiguring networks which are not based
on a fixed infrastructure, but are characterized by being infrastructure less, where devices have to
automatically generate the network in the initial phase, and maintain it through reconfiguration
procedures (if nodes’ mobility, or energy drain, etc..., cause disconnections). The main part of
the PhD activity has been focused on an analytical study on connectivity models for wireless ad
hoc and sensor networks, nevertheless a small part of my work was experimental. Anyway, both
the theoretical and experimental activities have had a common aim, related to the performance
evaluation of WASNs. Concerning the theoretical analysis, the objective of the connectivity
studies has been the evaluation of models for the interference estimation. This is due to the
fact that interference is the most important performance degradation cause in WASNs. As a
consequence, is very important to find an accurate model that allows its investigation, and I’ve
tried to obtain a model the most realistic and general as possible, in particular for the evaluation of
the interference coming from bounded interfering areas (i.e. a WiFi hot spot, a wireless covered
research laboratory, ...). On the other hand, the experimental activity has led to Throughput and
Packet Error Rare measurements on a real IEEE802.15.4 Wireless Sensor Network.
Mythic fertility, impurity, and creolization in the works of Octavia E. Butler
Creators: name: Mendoza, Bernabe Sebastian
Publisher: name: No Publisher Supplied
Year: 2020

description: My dissertation focuses on how Octavia Butler’s work intervenes in dominant conceptions of the human. The dualistic thinking that informs the notion of the human within Western discourse is attached to oppositional dichotomies that the genre of science fiction takes on as a human/nonhuman opposition in alien invasion contagion narratives. I connect Butler’s overturning of binary thinking to the work of Black and women of color feminism. Part of my own intervention in this project is to fully situate Butler’s work within the tradition of black feminist thought. I read her work through a creolizing methodology that brings together themes and discourses that disrupt oppositional binaries. The themes I weave together throughout this project and that I see as Butler herself also interweaving in order to overturn dualistic thinking include those associated with creolization, slavery, incest, black women’s reproductive rights and politics, the retelling of mythical and biblical myths attached to monstrous and damned female archetypes, the altering of the alien with the genre of science fiction, shapeshifting and its reconfiguring of gender, aleatory matter, and the Cartesian mind-body duality.

Particle production in models with helicity-0 graviton ghost in de Sitter spacetime

Year: 2008
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We revisit the problem of the helicity-0 ghost mode of massive graviton in the de Sitter background. In general, the presence of a ghost particle, which has negative energy, drives the vacuum to be unstable through pair production of ghost particles and ordinary particles. In the case that the vacuum state preserves the de Sitter invariance, the number density created by the pair production inevitably diverges due to unsuppressed ultra-violet(UV) contributions. In such cases one can immediately conclude that the model is not viable. However, in the massive gravity theory we cannot construct a vacuum state which respects the de Sitter invariance. Therefore the presence of a ghost does not immediately mean the breakdown of the model. Explicitly estimating the number density and the energy density of particles created by the pair production of two conformal scalar particles and one helicity-0 ghost graviton, we find that these densities both diverge. However, since models with helicity-0 ghost graviton have no de Sitter invariant vacuum state, it is rather natural to consider a UV cutoff scale in the three-dimensional momentum space. Then, even if we take the cutoff scale as large as the Planck scale, the created number density and energy density are well suppressed. In many models the cutoff scale is smaller than the Planck scale. In such models the created number density and the energy density are negligiblly small as long as only the physics below the cutoff scale is concerned.

description: Earth's distant past and potentially its future include extremely warm "hothouse" climate states, but little is known about how the atmosphere behaves in such states. One distinguishing characteristic of hothouse climates is that they feature lower-tropospheric radiative heating, rather than cooling, due to the closing of the water vapor infrared window regions. Previous work has suggested that this could lead to temperature inversions and significant changes in cloud cover, but no previous modeling of the hothouse regime has resolved convective-scale turbulent air motions and cloud cover directly, thus leaving many questions about hothouse radiative heating unanswered. Here, we conduct simulations that explicitly resolve convection and find that lower-tropospheric radiative heating in hothouse climates causes the hydrologic cycle to shift from a quasi-steady regime to a "relaxation oscillator" regime, in which precipitation occurs in short and intense outbursts separated by multi-day dry spells. The transition to the oscillatory regime is accompanied by strongly enhanced local precipitation fluxes, a significant increase in cloud cover, and a transiently positive (unstable) climate feedback parameter. Our results indicate that hothouse climates may feature a novel form of "temporal" convective self-organization, with implications for both cloud coverage and erosion processes.

description: The large number of people who refuse to get vaccines is one of the biggest challenges for the Indonesian government in dealing with the COVID-19 pandemic. Widespread misinformation and hoaxes about COVID-19 vaccines has made the level of public trust decreases. This paper was written to see how the public's opinion on the side effects of the three COVID-19 vaccines that have been spreading in Indonesia, among them are Sinovac, Astra Zeneca and Moderna. There will be a sentiment analysis and grouping of public conversations on Twitter with LDA regarding the side effects of the three vaccines. From the results obtained, it is expected to be a reference for the government or related parties in order to validate the issues that circulated among the society regarding the side effects of the COVID-19 vaccine. From the results of the analysis, it was found that in the Sinovac vaccine type, people tend to state that the side effects felt are quite mild, dominated by the words sleepy, achy & hungry. While for the Astra Zeneca & Moderna vaccine, people tend to state that the side effects are quite severe, such as fever, pain, and dizziness. The results of the analysis also found that the Astra Zeneca vaccine was the type of vaccine that received the most negative opinions from the public.

description: Ricerche mostrano che le pratiche cliniche orientate alla recovery, come la condivisione del processo decisionale dei progetti riabilitativi tra operatori e utenti, hanno il potenziale di migliorare la cura nell’ambito della salute mentale impattando positivamente sulla qualità di vita, sull’autonomia degli utenti e sugli esiti di salute. Considerando ciò, nell’Unità Operativa Complessa di Psichiatria di Borgo Roma di Verona, si sta puntando ad integrare i principi e i valori della recovery alla pratica clinica evidence-based, al fine di aumentare la possibilità di guarigione degli utenti, migliorando la specificità dei progetti riabilitativi e la loro partecipazione agli stessi. Per raggiungere questo obiettivo gli operatori sono stati formati all’utilizzo della Mental Health Recovery Star™, scala inglese che orienta i progetti di cura alla recovery supportando l’utente e il suo operatore di riferimento nella definizione, nel monitoraggio e nella valutazione co-prodotti dei percorsi di riabilitazione. Inoltre, è stato creato, per la prima volta nella nostra UOC, un gruppo sperimentale composto sia da utenti che da operatori, che mira alla discussione e al confronto liberi sul tema della recovery al fine di raggiungere obiettivi più ampi come l’empowerment. Aspiriamo alla creazione di un’ associazione di utenti che possa partecipare alle riunioni dipartimentali e alla formazione di utenti esperti in supporto tra pari. In questo poster illustreremo ciò che la nostra UOC sta facendo per raggiungere l’obiettivo di integrare l’approccio alla recovery alle usuali pratiche cliniche evidence-based così da poter puntare a percorsi di cura e guarigione innovativi.

description: A potential pathway of maternal distress affecting infant outcomes could be disruptions in maternal behavior during mother-infant interactions . However, studies are mostly observational and longitudinal in nature, with very few studies examining daily fluctuations in maternal mood and how this could affect caregiving and the infant. To address this issue, the current study will investigate the effect of maternal stress on infant physiology and behavior and the mediating role of maternal quality of behavior within an experimental design.

description: Starting from the famous Pauli problem on the possibility to associate quantum states with probabilities, the formulation of quantum mechanics in which quantum states are described by fair probability distributions (tomograms, i.e. tomographic probabilities) is reviewed in a pedagogical style. The relation between the quantum state description and the classical state description is elucidated. The difference of those sets of tomograms is described by inequalities equivalent to a complete set of uncertainty relations for the quantum domain and to nonnegativity of probability density on phase space in the classical domain. Intersection of such sets is studied. The mathematical mechanism which allows to construct different kinds of tomographic probabilities like symplectic tomograms, spin tomograms, photon number tomograms, etc., is clarified and a connection with abstract Hilbert space properties is established. Superposition rule and uncertainty relations in terms of probabilities as well as quantum basic equation like quantum evolution and energy spectra equations are given in explicit form. A method to check experimentally uncertainty relations is suggested using optical tomograms. Entanglement phenomena and the connection with semigroups acting on simplexes are studied in detail for spin states in the case of two qubits. The star-product formalism is associated with the tomographic probability formulation of quantum mechanics.

description: We study the nature of pressure-strain interaction at reconnection sites, detected by NASA's Magnetospheric Multiscale (MMS) Mission. We employ data from a series of published case studies, including a large-scale reconnection event at the magnetopause, three small-scale reconnection events at the magnetosheath current sheets, and one example of the recently discovered electron-only reconnection. In all instances, we find that the pressure-strain shows signature of conversion into (or from) internal energy at the reconnection site. The electron heating rate is larger than the ion heating rate and the compressive heating is dominant over the incompressive heating rate in all cases considered. The magnitude of thermal energy conversion rate is close to the electromagnetic energy conversion rate in the reconnection region. Although in most cases the pressure-strain interaction indicates that the particle internal energy is increasing, in one case the internal energy is decreasing. These observations indicate that the pressure-strain interaction can be used as an independent measure of energy conversion and dynamics in reconnection regions, in particular independent of measures based on the electromagnetic work. Finally, we explore a selected reconnection site in a turbulent Particle-in-Cell (PIC) simulation which further supports the observational results.

description: In this paper we compute predictions for the number of stellar collisions derived from analytic models based on the mean free path (MFP) approximation and compare them to the results of $N$-body simulations. Our goal is to identify the cluster conditions under which the MFP approximation remains valid. Adopting a range of particle numbers ($100\leq N\leq5000$) and different combinations of particle masses and radii, we explore three different channels leading to stellar collisions, all of which are expected to occur in realistic stellar environments. At high densities, binaries form from isolated three-body interactions of single stars. Hence, we consider collisions between single stars and collisions involving binary stars, after they form in our simulations. For the latter, we consider two channels for mergers, namely direct stellar collisions during chaotic single-binary interactions and perturbation-driven mergers of binaries due to random walks in eccentricity approaching unity. In the densest systems considered here, a very massive object is formed at the cluster centre, causing local stellar orbits to become increasingly Keplerian and the assumptions going into our analytic model to break down. Before reaching this limit, we obtain excellent agreement between our theoretical predictions and the simulations: the analytic rates are typically accurate to within one standard deviation for the entire parameter space considered here, but the agreement is best for short integration times. Our results have direct implications for blue straggler formation in dense star clusters, and stellar mergers in galactic nuclei hosting massive black holes.

description: Using data drawn from the Sloan Digital Sky Survey (SDSS) and the SDSS-II Supernova Survey, we study the local environments of confirmed type Ia supernovae (SNe Ia) in the nearby Universe. At 0.05 < z < 0.15, we find that SN Ia events in blue, star-forming galaxies occur preferentially in regions of lower galaxy density relative to galaxies of like stellar mass and star-formation rate, while SNe Ia in nearby red galaxies show no significant environment dependence within the measurement uncertainties. Even though our samples of SNe in red hosts are relatively small in number, tests on simulated galaxy samples suggest that the observed distribution of environments for red SN Ia hosts is in poor agreement with a cluster type Ia rate strongly elevated relative to the field rate. Finally, after considering the impact of galaxy morphology, stellar age, stellar metallicity, and other relevant galaxy properties, we conclude that the observed correlation between the SN Ia rate and environment in the star-forming galaxy population is likely driven by a gas-phase metallicity effect, such that prompt type Ia supernovae occur more often or are more luminous in metal-poor systems.
