description: This paper presents an all-electronic approach for loss compensation in metamaterials. This is achieved by embedding active-transistors based negative differential resistance (NDR) circuits in each unit cell of the metamaterial lattice. NDR circuits provide tunable loss compensation over a broad frequency range limited only by the maximum operating frequency of transistors that is reaching terahertz values in newer semiconductor processes. Design, simulation and experimental results of metamaterials composed of split ring resonators (SRR) with and without loss compensation circuits are presented.

description: This study examines Anne Carson’s use and abuse of the lyric form, elucidating how Carson reinvigorates the lyric poem with the power of the sublime, and theorizing the relationship between poetry and knowledge. Through three critical and historical inflections, “Symbolon: The Poetry of Anne Carson” contextualizes Carson’s synthetic approach to poetry alongside the work of her significant influences and her significant peers. In following two diverging themes in Carson’s work, the erotic and the thanatological, this dissertation posits a new way to understand Carson’s contribution to poetry in Canada. By illuminating the ways in which Carson proffers a significant challenge to both contemporary critical practices and contemporary poetic practices, “Symbolon: The Poetry of Anne Carson” traces the development of an alternative lyrical tradition – a tradition that manifests the sublime as a “counter-song” to the neo-Romanticism that pervades lyricism in Canada. This dissertation consists of five chapters. The Introduction, “Troubling Propositions,” links Carson’s reception by readers, critics, and academics to her unique poetics, elaborating on the controversies surrounding both her publications and her prestigious, international awards. Chapter one, “Synagôgê and Diairesis: Anne Carson’s Classical Precedents,” establishes the way the Classics influence Carson’s poetry and scholarship, including her theories of both desire and loss. Chapter two, “The Matter of History: Anne Carson’s Modern Inflections,” provides context for Carson’s poetic experimentalism, locating her concerns about historical representation among those of Ezra Pound, H. D. (Hilda Doolittle), Phyllis Webb, and P. K. Page. Chapter three, “Postmodern Relatives: Anne Carson’s Elusive Doubles,” theorizes her subversive use of the lyric in relation to Postmodernist epistemology, including an examination the work of her peers Sina Queyras and Lisa Robertson. In conclusion, “Symbolon: The Poetry of Anne Carson” speculates that Carson’s approach to the lyric both affirms the consanguinity of philosophy and poetics, and constitutes an alternative to the dominant lyrical tradition in Canada.
Regulation of gene expression in invasive and non-invasive Compositae weeds
Creators: name: Bell, Graeme Douglas Milton
Publisher: name: University of British Columbia
Year: 2010

description: Gene expression divergence between populations has been linked to adaptive morphological evolution and is thought to be a factor in the invasive success of certain weedy plants. Understanding the genetic basis of these regulatory changes can identify genes that have been under selection during adaptation to a new environment or new species interactions. A high-throughput sequencing approach was used to study the regulatory basis (cis and/or trans) of gene expression differences between native and invasive populations of Cirsium arvense (Canada thistle) by exploring patterns of differential gene expression and sequence variation. Parent and hybrid allele-specific expression ratios were compared to infer the relative effects of cis- and trans-regulatory change. Genes differentially regulated in cis are considered candidate genes involved in adaptation or weediness because there is evidence for selection acting primarily on cis-regulatory variation. Illumina sequencing of cDNA libraries derived from parents and hybrid pools resulted in a total of 82,713,256 paired-end (2x100bp) reads and 83.4% of these were mapped to a reference C. arvense transcriptome of 88,374 unigene sequences. Expression analysis and variant (SNPs and Indel) calling was performed to score the nature of regulatory divergence for the first 900 contigs, representing ~1% of the total dataset. Of the 40 high-confidence cases, 7 showed cis-effects, 6 showed trans-effects, 9 had varying degrees of both cis and trans, and 18 showed non-intermediate hybrid effects. A set of contigs that had high similarity to 63 known or confirmed stress-related genes, previously identified in studies of sunflower and Canada thistle, was also assayed for allelic imbalance. Of these, 2 cases showed a cis-effect, 2 showed both cis- and trans-effects, and 2 revealed hybrid effects. Contig 23614, an auxin-response transcription factor, was differentially regulated due to cis-effects and has been previously confirmed as drought-stress gene in both sunflower and C. arvense. This research identifies changes in gene expression that are driven by differential selective pressures in native and invasive populations. It also advances our understanding of the nature of genetic changes that drive gene expression evolution.

description: Two important invariants in classical algebraic topology are the homotopy groups and the homology groups. The first of these are notoriously difficult to compute while the second is reasonably easier. The Hurewicz homomorphism is a natural transformation between these invariants which can make computation of some homotopy groups easier. In this thesis we will look at the analogue of these invariants, and of the Hurewicz homomorphism, for the category of interest in modern stable homotopy theory.

description: Inspired by the swarming or flocking of animal systems we study groups of agents moving in unbounded 2D space. Individual trajectories derive from a ``bottom-up'' principle: individuals reorient to maximise their future path entropy over environmental states. This can be seen as a proxy for keeping options open, a principle that may confer evolutionary fitness in an uncertain world. We find an ordered (co-aligned) state naturally emerges, as well as disordered states or rotating clusters; similar phenotypes are observed in birds, insects and fish, respectively. The ordered state exhibits an order-disorder transition under two forms of noise: (i) standard additive orientational noise, applied to the post-decision orientations (ii) ``cognitive'' noise, overlaid onto each individual's model of the future paths of other agents. Unusually, the order increases at low noise, before later decreasing through the order-disorder transition as the noise increases further.

description: We present methods for pricing of American and European options under a Geometric Markov Renewal Process (GMRP) as the underlying asset model. We provide a detailed overview of the GMRP. Discussions of Markov processes, Geometric Brownian Motion, and GMRP approximation techniques are presented. We discuss the Aase trading model, with a MATLAB implementation. We discuss the Black-Scholes and binomial Cox-Ross-Rubinstein formulas for European and American options. We present results on Fixed Time Increments GMRP, with a derivation of a method for a limiting case of Fixed Time Increments GMRP (applicable to perpetual American options), complete with MATLAB implementations. We also present a MATLAB implementation for the pricing of European options under GMRP with an arbitrary jump distribution. We discuss diffusion and normal deviated approximations of a GMRP, and present MATLAB implementations for pricing American and European options. We follow this with a discussion of a Poisson approximation of a security market. A literature review is presented, together with an appendix including our MATLAB implementations. Conclusions and recommendations for future research directions conclude the paper.
Investigation of the role of ING1a in Cellular Senescence and ING1b in Ribosomal DNA transcription

description: The INhibitor of Growth (ING) proteins are type II tumor suppressors that regulate epigenetic state and transcription by functioning as stoichiometric members of histone acetyltransferase and histone deacetylase complexes. Expression of the ING1a isoform increases more than 10-fold during replicative senescence. ING1a overexpression itself induced all features of senescence examined. In this study we have identified and characterized a causal role for endocytosis and signal transduction in inducing senescence-associated phenotypes. ING1a regulated endocytosis through transcriptional activation of endocytic adaptor ITSN2. Inhibition of endocytosis altered growth factor signaling pathways leading to Rb-mediated inhibition of E2F activity, enforcing a senescence phenotype. Overexpression of ITSN2 itself induced senescence-associated characteristics in primary cells. The upstream causal role of endocytosis during senescence induction was further confirmed by ING1a-mediated increase in ITSN2 prior to the appearance of senescence markers and also by induction of senescence-associated phenotypes upon altering the stoichiometry of endocytosis regulators. ING1b isoform is well characterized in terms of regulation of cell growth and tumor suppression. Nucleolar localization of ING1b has been previously reported to be associated with stress-induced apoptosis. In this work we observe that ING1 regulates histone acetylation and the chromatin state of rDNA by recruiting HDAC1. ING1 also regulated recruitment of RNA Pol I- associated transcription factor UBF to rDNA, and affected levels of both rRNA and protein synthesis in cells. A role for ING1-mediated rRNA repression was also observed during PMA-induced differentiation of THP-1 cells. We observed that nucleolar localization of ING1 required its NTS motifs while recruitment of HDAC was dependent on the ING1 unique N-terminal region. Knock down of ING1 increased rRNA transcription and affected cellular proliferation during stress. This study identifies two novel mechanisms by which ING1 exerts its tumor suppressor function, by affecting mitogenic signaling pathways and regulating the major transcription process in cells, and confirms that epigenetic processes play an essential role in these process.
Isospin-conserving hadronic decay of the ${D_{s1}(2460)}$ into ${D_sπ^+π^-}$

description: The internal structure of the charm-strange mesons $D_{s0}^*(2317)$ and $D_{s1}(2460)$ are subject of intensive studies. Their widths are small because they decay dominantly through isospin-breaking hadronic channels $D_{s0}^*(2317)^+\to D_s^+π^0$ and $D_{s1}(2460)^+\to D_s^{*+}π^0$. The $D_{s1}(2460)$ can also decay into the hadronic final states $D_s^+ππ$, conserving isospin. In that case there is, however, a strong suppression from phase space. We study the transition $D_{s1}(2460)^+\to D_s^+π^+π^-$ in the scenario that the $D_{s1}(2460)$ is a $D^*K$ hadronic molecule. The $ππ$ final state interaction is taken into account through dispersion relations. We find that the ratio of the partial widths of the $Γ(D_{s1}(2460)^+\to D_s^+π^+π^-)/Γ(D_{s1}(2460)^+\to D_s^{*+}π^0)$ obtained in the molecular picture is consistent with the existing experimental measurement. More interestingly, we demonstrate that the $π^+π^-$ invariant mass distribution shows a double bump structure, which can be used to disentangle the hadronic molecular picture from the compact state picture for the $D_{s1}(2460)^+$. Predictions on the $B_{s1}^0\to B_s^0π^+π^-$ are also made.

description: We address the crystallization of monodisperse hard spheres in terms of the properties of finite- size crystalline clusters. By means of large scale event-driven Molecular Dynamics simulations, we study systems at different packing fractions ϕ ranging from weakly supersaturated state points to glassy ones, covering different nucleation regimes. We find that such regimes also result in different properties of the crystalline clusters: compact clusters are formed in the classical-nucleation-theory regime (ϕ \leq 0.54), while a crossover to fractal, ramified clusters is encountered upon increasing packing fraction (ϕ \geq 0.56), where nucleation is more spinodal-like. We draw an analogy between macroscopic crystallization of our clusters and percolation of attractive systems to provide ideas on how the packing fraction influences the final structure of the macroscopic crystals. In our previous work (Phys. Rev. Lett., 106, 215701, 2011), we have demonstrated how crystallization from a glass (at ϕ > 0.58) happens via a gradual (many-step) mechanism: in this paper we show how the mechanism of gradual growth seems to hold also in super-saturated systems just above freezing showing that static properties of clusters are not much affected by dynamics.

description: Superconducting single flux quantum (SFQ) circuits can process information at extremely high speeds, in the range of hundreds of GHz. SFQ circuits are based on Josephson junction cells for switching logic and ballistic transmission for transferring SFQ pulses. Multi-chip modules (MCM) are often used to implement larger complex designs, which cannot be fit onto a single chip. We have optimized the design of wideband interconnects for transferring signals and SFQ pulses between chips in flip-chip MCMs and evaluated the importance of several design parameters such as the geometry of bump pads on chips, length of passive micro-strip lines (MSL)s, number of corners in MSLs as well as flux trapping and fabrication effects on the operating margins of the MCMs. Several test circuits have been designed to evaluate the above mentioned features and fabricated in the framework of 4.5-kA/cm2 HYPRES process. The MCMs bumps for electrical connections have been deposited using the waferlevel electroplating process. We have found that, at the optimized configuration, the maximum operating frequency of the MCM test circuit, a ring oscillator with chip-to-chip connections, approaches 100 GHz and is not noticeably affected by the presence of MCM interconnects, decreasing only about 3% with respect to the same circuit with no inter-chip connections.

description: Dairy cows require amino acids (AA) in the correct amount and profile to maximize milk protein secretion. This study was conducted to examine the effects of a deficiency of 3 essential AA - phenylalanine (Phe), threonine (Thr) and tryptophan (Trp) - on mammary metabolism and milk production. Five Holstein cows were abomasally infused with water or AA solutions that contained all AA, or were deficient in Phe, Thr, or Trp. Milk and milk protein yields decreased with a deficiency of Phe or Thr but not Trp. Arterial concentrations of Phe, Thr, and Trp decreased with their respective deletions, whereas concentrations of metabolites that serve as energy substrates were unaffected by treatment. Mammary plasma flow and mammary uptake of several AA changed in response to treatments, demonstrating that the mammary gland can respond to changes in nutrient supply in an attempt to maximize milk synthesis.
Improving Heuristics Through Relaxed Search - An Analysis of TP4 and HSP*a in the 2004 Planning Competition

description: The hm admissible heuristics for (sequential and temporal) regression planning are defined by a parameterized relaxation of the optimal cost function in the regression search space, where the parameter m offers a trade-off between the accuracy and computational cost of theheuristic. Existing methods for computing the hm heuristic require time exponential in m, limiting them to small values (m andlt= 2). The hm heuristic can also be viewed as the optimal cost function in a relaxation of the search space: this paper presents relaxed search, a method for computing this function partially by searching in the relaxed space. The relaxed search method, because it computes hm only partially, is computationally cheaper and therefore usable for higher values of m. The (complete) hm heuristic is combined with partial hm heuristics, for m = 3,..., computed by relaxed search, resulting in a more accurate heuristic. This use of the relaxed search method to improve on the hm heuristic is evaluated by comparing two optimal temporal planners: TP4, which does not use it, and HSP*a, which uses it but is otherwise identical to TP4. The comparison is made on the domains used in the 2004 International Planning Competition, in which both planners participated. Relaxed search is found to be cost effective in some of these domains, but not all. Analysis reveals a characterization of the domains in which relaxed search can be expected to be cost effective, in terms of two measures on the original and relaxed search spaces. In the domains where relaxed search is cost effective, expanding small states is computationally cheaper than expanding large states and small states tend to have small successor states.

description: This paper presents a deep learning-based pipeline for categorizing Bengali toxic comments, in which at first a binary classification model is used to determine whether a comment is toxic or not, and then a multi-label classifier is employed to determine which toxicity type the comment belongs to. For this purpose, we have prepared a manually labeled dataset consisting of 16,073 instances among which 8,488 are Toxic and any toxic comment may correspond to one or more of the six toxic categories - vulgar, hate, religious, threat, troll, and insult simultaneously. Long Short Term Memory (LSTM) with BERT Embedding achieved 89.42% accuracy for the binary classification task while as a multi-label classifier, a combination of Convolutional Neural Network and Bi-directional Long Short Term Memory (CNN-BiLSTM) with attention mechanism achieved 78.92% accuracy and 0.86 as weighted F1-score. To explain the predictions and interpret the word feature importance during classification by the proposed models, we utilized Local Interpretable Model-Agnostic Explanations (LIME) framework. We have made our dataset public and can be accessed at - https://github.com/deepu099cse/Multi-Labeled-Bengali-Toxic-Comments-Classification
Gated-ness, Income Segregation and Neighbourhood Cohesion in Two Western Canadian Metropolises

description: This research investigated the relation between the degree of gated-ness of a neighbourhood and the level of neighbourhood cohesion among its residents. Such an investigation was prompted by the current practice of municipal planners for promoting a grid pattern of streets for neighbourhoods and linking such a pattern with principles of resilience and connectedness while at the same time condemning altogether the enclave pattern of curvilinear streets, loops and cul-de-sacs as being non-resilient and non-sustainable. Municipal planners seem to overlook the reasons behind the morphological development of postwar suburbs as well as overlook, in particular, socio-psychological effects of their physical structure and access configuration. This research introduces new typologies in order to differentiate neighbourhoods along those two structural aspects. By undertaking a comparative analysis of four case studies in two Western Canadian metropolises, this research argues that semi-gated neighbourhoods raise cohesion among residents. The major findings of the research are that residents’ sense of neighbourhood cohesion, for both its affective and interactive dimensions, increased in the case of neighbourhoods that had a sense of enveloping space, a sense of entry into a domain that is signalled by the degree of exclusion and seclusion of the development. This research does not claim that all neighbourhoods need to be single access ones. Rather, it suggests that in as much as a neighbourhood is successful in conveying a cohesive image for such a domain, in as much do residents identify with the neighbourhood and with each other. The aesthetic quality of such a domain plays a role of in-forming residents who gradually develop an embodied space such that residents of the neighbourhood could be identifiable from outsiders. Such a process of in-forming and embodiment sets a common ground for social acceptance, sense of familiarity, and facilitates social interaction among residents who have developed common norms and values over time.

description: The growing demand for indoor navigation applications has promoted the implementation of navigation techniques on handheld devices. An accurate and reliable indoor navigation system hosted on handheld devices would benefit many consumer industries. MEMS (Micro-Electromechanical System) sensors can provide a short-term accurate navigation solution. WiFi-based (Wireless Fidelity) positioning is another potential technology for indoor navigation, which only uses pre-existing WiFi infrastructures and is a good source to aid the MEMS-based navigation solution. However, WiFi positioning requires databases to estimate the user position. The pre-surveys for building and maintaining the WiFi databases make most current WiFi positioning systems are not automatic. Currently, it remains difficult to find an automatic and accurate indoor navigation system on typical handheld devices. However, the complementary characteristics of MEMS sensors and WiFi offer an efficient integration for indoor navigation applications. Two automatic WiFi Positioning Services (WPSs) based on trilateration and fingerprinting are investigated in this research, which both consist of the background survey service and WiFi positioning service. Both WPSs provide WiFi positioning solutions, with no cost to build and to maintain WiFi databases. This removes the limitations that most current WPSs require time-consuming and labor-intensive pre-surveys to build the databases. Different approaches are investigated to improve the accuracy of both the WiFi databases and the user’s positions in indoor environments. The developed two automatic WPSs are also compared. An innovative MEMS navigation solution, based on motion constraints and the integration of INS (Inertial Navigation System) and PDR (Pedestrian Dead Reckoning), is built on handheld devices. LC (Loosely-coupled) integration and TC (Tightly-coupled) integration are implemented for WiFi and MEMS sensors to further limit the drifts of MEMS sensors. The navigation performances of PDR, INS, the PDR/INS-integrated MEMS solution, the LC integration solution, and the TC integration solution are compared in this research. The test results also show its average positioning error of TC integration in various trajectories is 0.01% of INS, 10.38% of PDR, 32.11% of the developed MEMS solution, and 64.58% of LC integration. This developed TC integration solution can be used in both environments with dense and sparse deployments of WiFi APs (Access Points).

description: Climate change has reduced the width and breadth of sea ice in the waters of the Canadian Arctic, rendering the region more accessible to southern interests, particularly shipping, than at any time in its history. The realities of an emergent Arctic have rekindled old fears regarding the nature and extent of Canadian sovereignty over the waters of its Arctic Archipelago. These fears are related to the historically and legally contested nature of Canadian claims. While the Canadian government is asserting its sovereignty in the Arctic region, the federal organizations that are the instruments of sovereignty assertion are both impacting the manner in which Canada’s Arctic foreign policy is conducted and affecting Canada’s sovereignty claims. This paper investigates said organizational effects through interviews conducted with high ranking members, current and retired, of the Royal Canadian Navy, The Canadian Coast Guard, Transport Canada and the Department of Foreign Affairs and International Trade.

Submerged in the Greater Will For 2 cellos, choir (in four parts) and sub tone.Dedicated to Judith Hamman and Tristen Parr.
PROGRAM NOTEThe title refers to one of he challenges of democracy: where notions of individualism are consumed within a greater overarching will. This is played out in the piece, as choir sections mirror and copy each other, and the cello duet blend in and out of the mass of singers.
The score is proportional, with the highest point of the screen being the highest pitch reference, the bottom being the lowest pitch reference. Line thickness indicates dynamic (should be pp – mf). When text is black, it applies to all voices. Coloured text is specific to that part. The electronics are embedded in the score and should be played through one or more subwoofers, using the mini jack line out of an ipad playing the score.
NOTE FOR PERFORMANCE
The majority of my compositions use scores that are read on an iPad tablet computer, using the Decibel ScorePlayer, an application available on the App Store . Any fixed media is embedded in the score, and some feature automated functions. In the case of ensemble works, multiple iPads can be networked on a LAN or over the Internet so parts can be read in a synchronised way. You should upload the score file (ending with.dsz) to your iPad from your computer via AirDrop on an Apple, or cable from a PC. Instructions on how to do this and using the Decibel ScorePlayer, more generally are included in the Application, which ships with five other scores. Thus my works have different versions of the score, as you may see above. A PDF/PNG file of the score ‘image’, a DSZ file to upload onto the iPad for performance, and for some less complex scores, a video version. Hardcopies are also available from my publisher. You can find out more about the Decibel ScorePlayer, and how to make your own scores for it, here.

description: We investigate graph transformations, defined using Datalog-like rules based on acyclic conjunctive two-way regular path queries (acyclic C2RPQs), and we study two fundamental static analysis problems: type checking and equivalence of transformations in the presence of graph schemas. Additionally, we investigate the problem of target schema elicitation, which aims to construct a schema that closely captures all outputs of a transformation over graphs conforming to the input schema. We show all these problems are in EXPTIME by reducing them to C2RPQ containment modulo schema; we also provide matching lower bounds. We use cycle reversing to reduce query containment to the problem of unrestricted (finite or infinite) satisfiability of C2RPQs modulo a theory expressed in a description logic.

description: We are carrying out multi-frequency radio continuum observations, using the Australia Telescope Compact Array, to systematically search for collimated ionized jets towards high-mass young stellar objects (HMYSOs). Here we report observations at 1.4, 2.4, 4.8 and 8.6 GHz, made with angular resolutions of about 7, 4, 2, and 1 arcsec, respectively, towards six objects of a sample of 33 southern HMYSOs thought to be in very early stages of evolution. The objects in the sample were selected from radio and infrared catalogs by having positive radio spectral indices and being luminous (L_bol > 20,000 L_sun), but underluminous in radio emission compared to that expected from its bolometric luminosity. This criteria makes the radio sources good candidates for being ionized jets. As part of this systematic search, two ionized jets have been discovered: one previously published and the other reported here. The rest of the observed candidates correspond to three hypercompact hii regions and two ultracompact hii regions. The two jets discovered are associated with two of the most luminous (70,000 and 100,000 Lsun) HMYSOs known to harbor this type of objects, showing that the phenomena of collimated ionized winds appears in the formation process of stars at least up to masses of ~ 20 M_sun and provides strong evidence for a disk-mediated accretion scenario for the formation of high-mass stars. From the incidence of jets in our sample, we estimate that the jet phase in high-mass protostars lasts for 40,000 yr.

description: This thesis investigates the ability of a vector-based Global Positioning System (GPS) receiver and an ultra-tight GPS/inertial receiver to detect and mitigate Continuous Wave (CW) interference in tracking and navigation domains. In this work, an Interference Detector (ID) is incorporated into the tracking domain of a GPS software receiver and a new observation weighting (OW) algorithm is developed to help classify GPS measurements when CW signal is present. Results show that both vector-based and ultra-tight GPS receivers, accompanied by the ID and OW, offer better navigation solution accuracies in CW jamming than their un-aided counterparts. Specifically, aided receivers improved the horizontal position approximately by a factor of two, while the horizontal velocity errors of the aided vector-based receiver were reduced by a factor of four compared to that of the un-aided counterpart during interference. Also, the novel OW technique set more appropriate observation variances than the carrier-to-noise (C/N0) weighting in jamming.

description: Magnetic fields of low-mass stars and planets are thought to originate from self-excited dynamo action in their convective interiors. Observations reveal a variety of field topologies ranging from large-scale, axial dipole to more structured magnetic fields. In this article, we investigate more than 70 three-dimensional, self-consistent dynamo models obtained by direct numerical simulations. The control parameters, the aspect ratio and the mechanical boundary conditions have been varied to build up this sample of models. Both, strongly dipolar and multipolar models have been obtained. We show that these dynamo regimes can in general be distinguished by the ratio of a typical convective length scale to the Rossby radius. Models with a predominantly dipolar magnetic field were obtained, if the convective length scale is at least an order of magnitude larger than the Rossby radius. Moreover, we highlight the role of the strong shear associated with the geostrophic zonal flow for models with stress-free boundary conditions. In this case, the above transition disappears and is replaced by a region of bistability for which dipolar and multipolar dynamos co-exist. We interpret our results in terms of dynamo eigenmodes using the so-called test-field method. We can thus show that models in the dipolar regime are characterized by an isolated 'single mode'. Competing overtones become significant as the boundary to multipolar dynamos is approached. We discuss how these findings relate to previous models and to observations.

title: The Effect of Water Conditions on Decomposition Rate: A Comparative Study of the Estimation of Post-mortem Submersion Interval

description: Many factors affect aquatic decomposition and the accuracy of Post-mortem Submersion Interval (PMSI) estimations but have not been researched thoroughly. The extent of decomposition in bodies recovered from water is measured using visual decomposition scoring systems (DSS). The applicability of the Heaton, van Daalen and Reh DSS is limited because they were developed with predominantly pale-skinned individuals in temperate climates. This PhD aimed to (1) determine the effect of water temperature, hardness, salinity, and current on decomposition rate in human analogues, (2) compare the effectiveness and suitability of these DSS for assessing decomposition changes in human analogues/human remains and estimating PMSI in dark-skinned individuals. Laboratory studies, where 660 mice decomposed for 35 days, were conducted to investigate the effect of salinity, hardness and current on decomposition rate. To augment the laboratory results with larger human analogues, 35 pigs were decomposed for 70 days in water of varied salinity. To evaluate the accuracy of the DSS in PMSI estimation of human cases, the Heaton, van Daalen and Reh DSS to assess the extent of decomposition visible in pictures of drowning victims from the Netherlands, U.K., and South Africa and compared with known PMSI. A ‘drowning database’ of data from global drowning cases cited in scientific literature and media was collated to understand worldwide drowning demographics. This research demonstrated that temperature, salinity, hardness, and current significantly affected the decomposition rate of human analogues (p<0.05) and has shown for the first time that discolouration changes can be misleading in dark skin-toned individuals when using the DSS, and these DSS are inaccurate for estimating the PMSI of dark and pale-skinned bodies in advanced decomposition states or recovered in winter. Recommendations for applying the DSS to dark-skinned individuals have been made to improve the estimation of PMSI. Therefore, temperature, salinity, current, and hardness levels should be considered when estimating the PMSI of bodies recovered from marine environments, and more global studies should be conducted to improve the suitability of these DSS in assessing decomposition and estimating PMSI in darker-skin-toned individuals.

PROGRAM NOTE

Dark Water focuses on the narrative of a deep-sea environment that unexpectedly manifests in the walls of a grieving women’s suburban dwelling; an impossible, flooded inner-architecture. It explores familial trauma through the darkly surreal tale of a woman who discovers an ocean within her house. The life forms that dwell in this space are both real and a manifestation of the resident’s internal psychological state, as she comes to terms with the death of her mother. Dark Water is underscored by both a sense of human loss and contemporary concerns around habitat loss within our oceans.

description: Substations are among the most important components of electrical transmission and distribution systems in the world. Unfortunately, some electrical equipment in substations is suitable place for animals to perch, roost, and hunt leading to their electrocution and possible power outages. Researchers have proposed different solutions to protect these animals from electrocution such as covering the electrical equipment. This solution requires field work to determine the dimensions of electrical equipment within high voltage environments which is potentially dangerous. Remote sensing methods can provide a suitable means to obtain measurements while mitigating such danger, because the field worker can stay a safe distance away from hazardous equipment such as power lines and hot connections. In this work, analysis of images taken from electrical substations is used to obtain measurements of equipment of interest. The main idea of this work is that hot connections are placed somewhere between insulators and power lines or insulators and bus pipes. Thus, if centerlines of insulators and power lines are extracted, the position of the hot connections will be known. Therefore, different feature-based algorithms are developed to extract insulators and power lines which will help in extracting hot connections. These algorithms include: 1) an automated texture/edge-based algorithm for insulator extraction, 2) an automatic edge-based power line extraction, and 3) a semi-automatic snake-based power line extraction. Then, the main objective of this thesis is to extract insulators and power lines from imagery of electrical substations. The extraction of bus pipes is not directly addressed; however, the power line extraction algorithms can be used to extract some of bus pipes, too.

description: Celem niniejszego artykułu jest przybliżenie konsekwencji wciąż postępującego zjawiska liberalizacji przepisów dotyczących upadłości konsumenckiej. Nowela z 30 sierpnia 2019 r. znacznie rozszerzyła zakres zdolności upadłościowej i w rezultacie ułatwiła ogłoszenie upadłości i otrzymanie oddłużenia. Konsekwencje takiego zabiegu legislacyjnego to istotne zwiększenie ilości spraw upadłościowych, osłabienie pozycji wierzycieli względem dłużników i zmiana przyjętego w Polsce modelu upadłości z modelu umiarkowanego na liberalny. Ponadto w artykule zostały przybliżone nowe rozwiązania natury proceduralnej, które miały przygotować sądy na masowy przypływ spraw. Jednakże jak wynika z analizy przyjętych zmian, procedura zostanie tylko jeszcze bardziej skomplikowana i przedłużona.
description: The purpose of this article is to bring closer the consequences of the still ongoing liberalisation of personal bankruptcy legislation. The amendment of 30 August 2019 significantly expanded the scope of bankruptcy capacity and consequently made it easier to declare bankruptcy and receive debt relief. The consequences of such a legislative procedure are a significant increase in the number of bankruptcy cases, weakening of the position of creditors towards debtors, and a change in the model of bankruptcy adopted in Poland, from a moderate to a liberal one. However, as the analysis of the adopted changes shows, the procedure will only be even more complicated and prolonged.
