description: The colonization of Canada has produced deleterious effects for the First Nations peoples that originally inhabited the land. Through sharing stories with a number of First Nations craft producers the objective of this research was to capture the endurance of First Nations culture beyond the disastrous effects of colonization and repression faced by the First Peoples of this continent. This study investigates the production of craft goods in First Nations communities by building on the concept of the narrative embedded in the material craft culture. By narrative, this study refers to the culturally specific ways that stories are created and maintained to preserve elements of culture and society. Craft goods continue to be produced and used in these communities as a way of preserving and reproducing the specific tribal knowledges that exist within these groups. Data in this project comes from semi-structured interviews with Indigenous craft makers. The methodology was developed to confront the positionality of a non-Indigenous researcher pursuing research objectives in a First Nations community and with the aim to be mindful and mitigate the effects of social privilege and power in the analysis of the data. Interviews and notes were analyzed through a hybrid of narrative and thematic analysis. The themes emerging from preliminary analysis of the data fit within a theoretical framework that centres and privileges Indigenous experience and perspective. Themes include: spirituality, family, animals, social structure, and resistance. These themes contribute to a larger cultural narrative of relationality and endurance embedded in the Indigenous material craft culture being investigated in the research. Together, these themes offer a clearer vision of the First Nations perspective and what it means to maintain a distinct cultural identity under the ongoing campaign of colonization.

description: Clionamines A-D (2.6-2.9) are new aminosteroids isolated from South African specimens of the sponge Cliona celata. All four compounds (2.6-2.9) are activators of autophagy in MCF-7 cells. Autophagy is a catabolic process that plays an important role in maintaining cellular homeostasis. Autophagy is also directly involved in the removal of bacterial and viral antigens and in the development of cancerous tumors. The novel sesterterpenoid ansellone A (3.4) was isolated from the nudibranch Cadlina luteomarginata and was later found to have been sequestered by the nudibranch from the sponge Phorbas sp. Ansellone A (3.4) is an activator of the cAMP signalling pathway. Following the isolation of 3.4, the novel sesterterpenoids ansellones B-D (4.3-4.5) as well as alotaketal E (4.6) were isolated from the sponge Phorbas sp. and were found to also be activators of the cAMP signalling pathway. Several bacterial isolates were obtained from the sponge Phorbas sp. in order to investigate the possibility that the ansellones and the alotaketals isolated from this sponge were biosynthesized by a bacterial symbiont. Since these sesterterpenoids were activators of the cAMP signalling pathway, the investigation was conducted using bioassay guided fractionation of the bacterial isolates. The new meroterpenoid phorbasolic acid (5.1) was isolated, but no sesterterpenoids were found in the bacterial isolates. In an effort to identify molecules with antibiotic properties, a biological assay was designed to screen for inhibitors of the citrate synthase type II enzyme. One aspect of this enzyme that is of therapeutic interest is that Gram-negative bacteria possess a very different isoform of the enzyme than Gram-positive bacteria and eukaryotes. Therefore, an antibiotic specific to type II citrate synthase would target Gram-negative bacteria selectively. An extract from a culture of Bacillus pumillus inhibited the enzyme in the assay. Although the molecule responsible for this effect has yet to be identified, the new aliphatic amide 12-methyl tridecanamide (6.1) was isolated.

description: ‘Through a Lens Darkly: Investigating “Reality” in The Village’ documents the process of rewriting my novel The Village. Organised into three sections, in addition to the full manuscript of the published novel itself, this thesis sets out to examine the ways in which I sought to represent a particular authorial reality in the final draft, after registering its absence in the first version of the book. The first section tackles the process of writing the first draft, the response from my editor, and a distillation of the flaws in the story-telling approach that I felt were preventing the text from having an authentic quality at that point. The second section documents the first part of my endeavour to correct this, through my search for telling detail within video and audio recordings of Sanganer (the North Indian ‘prison-village’ on which The Village is modelled). The third section focuses on the specific influence of three writers on the style and content of the final draft of the novel: Doris Lessing, James Salter and Daniyal Mueenuddin. I read Lessing for insight on tackling issues of exotica and colonialism within the text, Salter for the ability to create a diffuse, ambiguous point of view (in order to force the reader to engage with his or her own viewpoint), and Mueenuddin for techniques to create a powerful sense of place. I have given examples of the ways in which my engagement with these aspects of craft had impact on the final, published version of The Village. A short summary of the novel is given in the appendix at the end of this document. All references to The Village: a doctoral thesis are to the manuscript of the novel supplied as the second part of this manuscript.

description: As embedded devices are becoming more pervasive in our everyday lives, they turn into an attractive target for adversaries. Despite their high value and large attack surface, applying automated testing techniques such as fuzzing is not straightforward for such devices. As fuzz testing firmware on constrained embedded devices is inefficient, state-of-the-art approaches instead opt to run the firmware in an emulator (through a process called re-hosting). However, existing approaches either use coarse-grained static models of hardware behavior or require manual effort to re-host the firmware. We propose a novel combination of lightweight program analysis, re-hosting, and fuzz testing to tackle these challenges. We present the design and implementation of Fuzzware, a software-only system to fuzz test unmodified monolithic firmware in a scalable way. By determining how hardware-generated values are actually used by the firmware logic, Fuzzware can automatically generate models that help focusing the fuzzing process on mutating the inputs that matter, which drastically improves its effectiveness. We evaluate our approach on synthetic and real-world targets comprising a total of 19 hardware platforms and 77 firmware images. Compared to state-of-the-art work, Fuzzware achieves up to 3.25 times the code coverage and our modeling approach reduces the size of the input space by up to 95.5%. The synthetic samples contain 66 unit tests for various hardware interactions, and we find that our approach is the first generic re-hosting solution to automatically pass all of them. Fuzzware discovered 15 completely new bugs including bugs in targets which were previously analyzed by other works; a total of 12 CVEs were assigned.

description: We study the large deviations of a simple noise-perturbed dynamical system having continuous sets of steady states, which mimick those found in some partial differential equations related, for example, to turbulence problems. The system is a two-dimensional nonlinear Langevin equation involving a dissipative, non-potential force, which has the essential effect of creating a line of stable fixed points (attracting line) touching a line of unstable fixed points (repelling line). Using different analytical and numerical techniques, we show that the stationary distribution of this system satisfies in the low-noise limit a large deviation principle containing two competing terms: i) a classical but sub-dominant large deviation term, which can be derived from the Freidlin-Wentzell theory of large deviations by studying the fluctuation paths or instantons of the system near the attracting line, and ii) a dominant large deviation term, which does not follow from the Freidlin-Wentzell theory, as it is related to fluctuation paths of zero action, referred to as sub-instantons, emanating from the repelling line. We discuss the nature of these sub-instantons, and show how they arise from the connection between the attracting and repelling lines. We also discuss in a more general way how we expect these to arise in more general stochastic systems having connected sets of stable and unstable fixed points, and how they should determine the large deviation properties of these systems.

title: A critical edition of Samuel Rowley's 'When you see me, you know me'
Creators: name: Howe, J.N
Publisher: name: Bath Spa University
Year: 2015

description: This edition presents a fully modernised and annotated text of Samuel Rowley’s 'When You See Me, You Know Me', first performed by Prince Henry’s Men at the Fortune playhouse c.1604. The earliest extant playtext to represent King Henry VIII as a character on the early modern stage, When You See Me dramatizes a number of key events in the Tudor king’s reign including, as per the play’s subtitle, ‘the birth and virtuous life of Edward, Prince of Wales’. The play was first printed in 1605, with subsequent editions appearing in 1613, 1621 and 1632. Despite its apparent success on the Fortune stage, however, the play has become increasingly marginalized since the mid-seventeenth century, receiving only cursory critical attention. In addition to making the text of Rowley’s play accessible to a modern readership, this edition aims to rehabilitate When You See Me as an important dramatization of the Henrician Reformation; it also seeks to draw attention to Rowley and his long and influential career in the early modern theatre. The introduction to the edition is divided into two main parts, focusing respectively on the author and the play; the latter is subdivided to include separate critical, bibliographical and editorial introductions. The Critical Introduction provides information on the play’s composition and performance history, including aspects of its performance on the Fortune stage and its position within the extant company repertory; the Bibliographical Introduction considers the play’s entrance in the Stationers’ Register and the manuscript used as printers’ copy, as well as the physical manufacture of its first edition and the text’s treatment in later and modern editions; and the Editorial Introduction provides comment on the specific methodologies employed in the production of the edition, with particular reference to the Arden Early Modern Drama editorial guidelines upon which the text is based. The appendices provide useful supplementary information, including Rowley’s likely source material; doubling charts; current locations of extant copies; bibliographical descriptions; press variants; and photographs of the copy-text.

description: Simulation studies of three thermal recovery processes used in Athabasca reservoirs have been carried out for a 10-year production period. The recovery processes studied are Steam-Assisted Gravity Drainage (SAGD), Fast-SAGD, and Expanding Solvent-SAGD (ES-SAGD). Normal pentane (n-C5) was the solvent of choice used in ES-SAGD simulations with its molar concentration varied from 2% to 5.9%. The main objective of this study is to conduct an economic analysis of the three recovery processes with the goal of determining the most economically viable process. The economic indicator that will be assessed to ascertain the most viable recovery process is their Net Present Value (NPV.) 2D simulation studies based on homogeneous Athabasca reservoirs have been performed. Results obtained show that of the three recovery processes, Fast-SAGD had the lowest cumulative oil produced, followed by SAGD and ES-SAGD, the highest. The cumulative oil produced also increased with increasing molar concentration of n-C5. Furthermore, it was shown that as expected, the CSOR of ES-SAGD was the lowest of them while that of Fast-SAGD was the highest. The CSOR of the ES-SAGD processes reduced as the concentration of the n-C5 increased. The economic analysis showed that of the three recovery processes, ES-SAGD is the most economically viable process. Furthermore, the effect of solvent on the viability of ES-SAGD over the other recovery processes is dependent on the price regime of pentane. In this analysis, two extreme price regimes were chosen and the result showed that for a low price regime, varying the molar ratios of n-C5 had a significant effect on the NPV up to a point before its effect diminishes. In fact, increasing the molar concentration of n-C5 from 2% to 3.76% significantly increased the NPV while further increasing it from 3.76% to 4% and thereafter to 5.9% had no noticeable effect. However, it seems that increasing it from 3.76% to 5.9% had a diminishing effect especially after the 3-year period. Nevertheless, the significant NPV improvement ES-SAGD has over SAGD and Fast-SAGD diminishes once the price regime of pentane is more than 3 times that of oil. In fact, this high price regime showed that 5.9% molar concentration of n-C5 is no longer more viable than the SAGD counterpart. There is still some benefit up till about 4% molar concentration of n-C5 but this benefit is greatly diminished. In conclusion, ES-SAGD has been shown to be the best recovery process for Athabasca reservoirs based on economics but further research is needed to evaluate the molar concentration that will provide the most economic benefit for a real Athabasca reservoir.

description: Schizophrenia (SZ) and intellectual disability (ID) are both included in the continuum of neurodevelopmental disorders (NDDs). DNA methylation is known to be important in the occurrence of NDDs. Family study is conducive to eliminate the effects of relative epigenetic backgrounds, and to screen for differentially methylated positions (DMPs) and regions (DMRs) that are truly associated with NDDs. Four monozygotic twin families were recruited, and both twin individuals suffered from NDDs (either SZ, ID, or SZ plus ID). Genome-wide methylation analysis was performed in all samples and each family. DMPs and DMRs between NDD patients and unaffected individuals were identified. Functional and pathway enrichment analyses were performed on the annotated genes. Two significant DMPs annotated to CYP2E1 were found in all samples. In Family One, 1,476 DMPs mapped to 880 genes, and 162 DMRs overlapping with 153 unique genes were recognized. Our results suggested that the altered methylation levels of FYN, STAT3, RAC1, and NR4A2 were associated with the development of SZ and ID. Neurodevelopment and the immune system may participate in the occurrence of SZ and ID. Our findings suggested that DNA methylation participated in the development of NDDs by affecting neurodevelopment and the immune system.

title: Facilitating human computer interaction artworks: the nature of interactivity within architectonic schemes
Creators: name: Diduch, L
Publisher: name: Bath Spa University
Year: 2015

description: This paper examines Human Computer Interaction artworks and how notions of interactivity are evolving due to the presence of expanding architectonic schemes in and around these artworks. This research draws on sources that use rapid ethnographic methodologies to collect data and argues for a redefinition of current understandings of interactivity within the field of multimedia and art practice. My research has been practice based and is reflected in the artworks and writing that I have produced. Participants' highly differential levels of commitment with an artwork while examining understandings of co-creativity are explored. Artworks of contemporary artists who use Human Computer Interaction and computer technologies to experiment with the idea of expansiveness through spectator participation in the field of HCI artworks are discussed. In varying degrees, and due to varying aspects of immateriality, artworks are considered as being extended beyond the confines of both the multimedia interface and even the architectural structure of the art gallery or exhibition space. Terms such as architectonics, touchpoints, configuration and agora are employed when describing interactive processes in the field of Fine Art installation. Modernist writer and critic R.H. Wilenski is referenced regarding the relationships between art, architecture and the artist/spectator. Current and past understandings of interactivity, as well as terms used by contemporary interface designers such as Don Norman and Dan Saffer are used in relation to the study of HCI artworks. In addition, this paper focuses on the modes in which audiences 'look away' and use a range of devices that exist around artworks to expand the architectonic schemes in and around them...[cut for length].
Factoring and Pairings Are Not Necessary for IO: Circular-Secure LWE Suffices

description: We construct indistinguishability obfuscation (iO) solely under circular-security properties of encryption schemes based on the Learning with Errors (LWE) problem. Circular-security assumptions were used before to construct (non-leveled) fully-homomorphic encryption (FHE), but our assumption is stronger and requires circular randomness-leakage-resilience. In contrast with prior works, this assumption can be conjectured to be post-quantum secure; yielding the first provably secure iO construction that is (plausibly) post-quantum secure. Our work follows the high-level outline of the recent work of Gay and Pass [STOC 2021], who showed a way to remove the heuristic step from the homomorphic-encryption based iO approach of Brakerski, Döttling, Garg, and Malavolta [EUROCRYPT 2020]. They thus obtain a construction proved secure under circular security assumption of natural homomorphic encryption schemes – specifically, they use homomorphic encryption schemes based on LWE and DCR, respectively. In this work we show how to remove the DCR assumption and remain with a scheme based on the circular security of LWE alone. Along the way we relax some of the requirements in the Gay-Pass blueprint and thus obtain a scheme that is secure under a different assumption. Specifically, we do not require security in the presence of a key-cycle, but rather only in the presence of a key-randomness cycle. An additional contribution of our work is to point out a problem in one of the building blocks used by many iO candidates, including all existing provable post-quantum candidates. Namely, in the transformation from exponentially-efficient iO (XiO) from Lin, Pass, Seth and Telang [PKC 2016]. We show why their transformation inherently falls short of achieving the desired goal, and then rectify this situation by showing that shallow XiO (i.e. one where the obfuscator is depth-bounded) does translate to iO using LWE.

We show that when both cavities are intensely driven one can generate bipartite entanglement between any pair of the tripartite system, and that, due to entanglement sharing, optical-microwave entanglement is efficiently generated at the expense of microwave-mechanical and opto-mechanical entanglement.

description: The thermoelectric properties of cubic zincblend silicon carbide nanowires (SiCNWs) with nitrogen impurities and vacancies along [111] direction are theoretically studied by means of atomistic simulations. It is found that the thermoelectric figure of merit ZT of SiCNWs can be significantly enhanced by doping N impurities together with making Si vacancies. Aiming at obtaining a large ZT, we study possible energetically stable configurations, and disclose that, when N dopants locate at the center, a small number of Si vacancies at corners are most favored for n-type nanowires, while a large number of Si vacancies spreading into the flat edge sites are most favored for p-type nanowires. For the SiCNW with a diameter of 1.1 nm and a length of 4.6 nm, the ZT value for the n-type is shown capable of reaching 1.78 at 900K. The conditions to get higher ZT values for longer SiCNWs are also addressed.

How Byzantine is a Send Corruption?

Publisher: name: CISPA
Year: 2023

description: Consensus protocols enable n parties, each holding some input string, to agree on a common output even in the presence of corrupted parties. Recent work has pushed to understand the problem when a majority of parties may be corrupted thus providing higher resilience, and under various forms of corruptions. Zikas, Hauser, and Maurer introduced a model in which receive-corrupt parties may not receive messages sent to them, and send-corrupt parties may have their sent messages dropped. Otherwise, receive-corrupt and send-corrupt parties behave honestly and their inputs and outputs are constrained by the security definitions. Zikas, Hauser, and Maurer gave a perfectly secure, linear-round protocol for n>trcv+tsnd+3tbyz , where trcv , tsnd , and tbyz represent thresholds on receive-, send-, and byzantine-corruptions. We present the first expected constant-round protocol in the general corruption model tolerating n>trcv+2tsnd+2tbyz . In comparison, all current sublinear round consensus protocols fail if there exists even a single party which cannot communicate with some honest parties, but whose output must be consistent with the honest parties. While presenting our protocol, we explore the pathology of send-corruptions and characterize the difficulty of dealing with them in sublinear-round protocols. As an illustrative and surprising example (even though not in sublinear rounds), we show that the classical Dolev-Strong broadcast protocol degrades from tolerating tbyztrcv+tsnd+2tbyz when we constrain the adversary to either drop all or none of a sender’s messages in a round (we denote this model by spotty send corruptions). To our knowledge, our protocol for the spotty send corruption model is thus the first sublinear-round consensus protocol for a majority of online faulty parties in any model. Because we are unable to prove optimality of our protocol’s corruption budget in the general case, we leave open the question of optimal corruption tolerance for both send-corruptions and byzantine-corruptions.
The Precautionary Principle: Concepts, Tools, and Strategies for Analysis

description: In this thesis, I assess the Precautionary Principle (PP) as a guide to decision making in environmental policy. The PP says, roughly, that decision makers should act in advance of scientific certainty to protect against harms to the environment and public health. I argue that the main objections to the PP in the literature can be defended against and, further, that there is a need for such a principle due to the shortcomings of popular quantitative approaches to decision making. I also examine Stephen Gardiner’s influential interpretation of the PP as a version of the maximin decision rule. I argue that Gardiner’s interpretation makes the PP inapplicable in the epistemic situation of ignorance, a situation which most accurately characterizes the nature of our knowledge in many important environmental policy problems. I conclude that the PP should not be interpreted as a version of the maximin rule.
Long distance contribution to $K_{L}$-$K_{S}$ mass difference

description: We present a method to non-perturbatively determine the long-distance contribution to the $K_{L}$-$K_{S}$ mass difference. The calculation is performed on 2+1 flavor, domain wall fermion, $16^3\times32$ configurations with a 421 MeV pion mass and a kaon mass of 559 MeV . We include only current-current operators and drop all disconnected diagrams in the calculation. The largest contribution comes from quadratically divergent, short distance lattice artifacts. This quadratic divergence is eliminated through the GIM mechanism by introducing a valence charm quark. The remaining short distance effects are then removed by using RI/MOM technique which allows their exact replacement by the physical short distance part.
Two-Round Oblivious Linear Evaluation from Learning with Errors

Publisher: name: CISPA
Year: 2023

description: Oblivious Linear Evaluation (OLE) is the arithmetic analogue of the well-know oblivious transfer primitive. It allows a sender, holding an affine function f(x)=a+bx over a finite field or ring, to let a receiver learn f(w) for a w of the receiver’s choice. In terms of security, the sender remains oblivious of the receiver’s input w, whereas the receiver learns nothing beyond f(w) about f. In recent years, OLE has emerged as an essential building block to construct efficient, reusable and maliciously-secure two-party computation. In this work, we present efficient two-round protocols for OLE over large fields based on the Learning with Errors (LWE) assumption, providing a full arithmetic generalization of the oblivious transfer protocol of Peikert, Vaikuntanathan and Waters (CRYPTO 2008). At the technical core of our work is a novel extraction technique which allows to determine if a non-trivial multiple of some vector is close to a q-ary lattice.
Cranberry metabolomics : new approaches for phytochemical characterizations
Creators: name: Brown, Paula Naomi
Publisher: name: University of British Columbia

description: There is a long history of use and modern commercial importance of large (Vaccinium macrocarpon Aiton) and small cranberries (V. oxycoccus L. and V. vitis-idaea L.) in North America. While epidemiological research indicates cranberries have positive health benefits, identifying specific phytochemicals for disease prevention remains elusive. The central objective of this research was to develop phytochemical characterization tools for comparing commercially cultivated cranberries and two wild-harvested Vaccinium species. A method was developed and validated to quantify cyanidin-3-O-galactoside (C3Ga), cyanidin-3-O-glucoside (C3Gl), cyanidin-3-O-arabinoside (C3Ar), peonidin-3-O-galactoside (P3Ga) and peonidin-3-O-arabinoside (P3Ar) in cranberry fruit products. The relative standard deviation (%RSDr) of anthocyanins ranged from 1.77% to 3.31% with the method detection limit (MDL) for C3Ga, C3Gl, C3Ar, P3Ga, and P3Ar estimated at 0.018, 0.016, 0.006, 0.013, and 0.011 µg/mL, respectively. In biological replicates of V. macrocarpon cultivars, anthocyanin content (mg/g) was determined to be 7.98±5.83 in Ben Lear; 7.02±1.75 in Bergman; 6.05± 2.51 in GH1; 3.28± 1.88 in Pilgrim and 2.81 ±0.81 in Stevens. V. oxycoccus contained the five major anthocyanins with the ratio of glycosylated peonidins to cyanidins varying from V. macrocarpon. V. vitis-idaea contained no measurable glycosylated peonidins. Determination and statistical analysis of serotonin, melatonin and ascorbic acid content in the three Vaccinium species, found only vitamin C positively correlated with antioxidant activity. Metabolome comparisons made from untargeted metabolomics by ultra-fast liquid chromatography (UFLC) with time-of-flight (TOF) mass spectrometry (MS), found different pools of common metabolites extracted in methanol (7635), 70% ethanol (5832), and water (5664). Each cranberry matrix contained unique compounds; fruit=3680, product 1=3464, product 2=3500. Clustering was visualized using principal component and partial least squares discriminate analyses with application of univariate statistics to mitigate false discoveries. A significance algorithm found 1987, 716 and 1556 compounds (p-value<0.05) in methanol, 70% ethanol and water extracts, respectively. In metabolomic profiles of V. macrocarpon varietals 6481 compounds were conserved and 136 (Ben Lear), 84 (Bergman), 91 (GH1), 128 (Pilgrim) and 165 (Stevens) unique observations were made. Across the three Vaccinium species 8000-10,000 phytochemicals were detected with 4624 compounds conserved between them. Together these data establish targeted and untargeted methods for phytochemical characterization of cranberries, providing foundational chemotaxonomic knowledge and new insights into the maintenance of health in traditional North American diets.

description: Effective performance testing techniques are essential for understanding whether a Webbased system will meet its performance objectives. Such systems have to be characterized in terms of sessions; a session being a sequence of inter-dependent requests submitted by a user. Dependencies arise because some requests depend on the responses of earlier requests in a session. These dependencies should be reflected in the synthetic workloads used to test Web-based systems. This makes performance testing a challenge. This research proposes an approach to address this issue. This approach uses an application model that can be used to obtain valid request sequences representing how users interact with the application. These sequences can be used to automatically construct a synthetic workload with desired characteristics. The application model provides an indirection which allows a common set of workload generation tools for testing different applications. Consequently, less effort is needed in maintaining and developing the tools.

description: Studying the security and efficiency of blind signatures is an important goal for privacy sensitive applications. In particular, for large-scale settings (e.g., cryptocurrency tumblers), it is important for schemes to scale well with the number of users in the system. Unfortunately, all practical schemes either 1) rely on (very strong) number theoretic hardness assumptions and/or computationally expensive pairing operations over bilinear groups, or 2) support only a polylogarithmic number of concurrent (i.e., arbitrarily interleaved) signing sessions per public key. In this work, we revisit the security of two pairing-free blind signature schemes in the Algebraic Group Model (AGM) + Random Oracle Model (ROM). Concretely, 1. We consider the security of Abe’s scheme (EUROCRYPT ‘01), which is known to have a flawed proof in the plain ROM. We adapt the scheme to allow a partially blind variant and give a proof of the new scheme under the discrete logarithm assumption in the AGM+ROM, even for (polynomially many) concurrent signing sessions. 2. We then prove that the popular blind Schnorr scheme is secure under the one-more discrete logarithm assumption if the signatures are issued sequentially. While the work of Fuchsbauer et al. (EUROCRYPT ‘20) proves the security of the blind Schnorr scheme for concurrent signing sessions in the AGM+ROM, its underlying assumption, ROS, is proven false by Benhamouda et al. (EUROCRYPT ‘21) when more than polylogarithmically many signatures are issued. Given the recent progress, we present the first security analysis of the blind Schnorr scheme in the slightly weaker sequential setting. We also show that our security proof reduces from the weakest possible assumption, with respect to known reduction techniques.

description: This paper reports on, and supplies the checklists for, the known foodplant population currently growing around Diepkloof Rock Shelter, South Africa, within radii of ∼12.5 km, ∼35 km and ∼70 km. It demonstrates that many of the species identified from the shelter’s Middle Stone Age charcoal record still grow on the landscape today and that 33 of the ancient charcoal-identified species are historically known as foodplants in southern Africa. With this contribution the current foodplant species that could serve as dietary resources are extended to 81 within a day’s return trip (∼12.5 km) from the site, 158 within the ∼35 km radius and 170 on the greater foraging landscape extending up to ∼ 70 km from Diepkloof. Data are presented that indicate the proportional increases in plant growth forms and edible plant parts by extending foraging ranges. Initial interpretation of the data shows that foragers may have had adequate access to herbs and shrubs from which leafy vegetables and fruits can be collected, as well as hydrophytes (such as waterblommetjies) within a day’s return trip. To increase especially access to energy-rich corms and roots, they may have used additional/other camp sites or home bases to exploit their ∼35 km foraging range. By travelling over longer distances, access to grass grains that also serve as famine foods can be exponentially increased.
Dynamic modeling of solution-gas drive in heavy oil reservoirs

description: Bibliography: p. 102-108
description: Some heavy oil reservoirs in Canada show atypically high production rates and high primary oil recoveries under solution-gas drive. Much attention has been given to the anomalous behaviour observed in such heavy oil reservoirs, and several models have been suggested to explain these anomalies. There are possibly two classes of effects responsible for the unusual behaviour of solution-gas drive in heavy oil reservoirs, including fluid effects and rock/geomechanical effects. However, since the role of geo-mechanics has been studied by several investigators, this study focuses exclusively on fluid effects. Two main features are different between solution-gas drive in heavy oils and the traditional view of solution-gas drive as seen to function in light oil reservoirs. In heavy oils, the concentration of gas in the oil can be greater than the equilibrium value, giving rise to the oil becoming supersaturated. In addition to this, recovery and gas mobility show rate dependent behaviour in heavy oils. Both of these effects are taken into consideration in this study. In this study, a dynamic model is developed which captures many important processes that affect heavy oil recovery. The non-equilibrium early time behaviour is modeled by introducing a kinetic equation describing the rate of evolution of solution gas into free gas. The equation is derived based on a phenomenological analysis which takes into account bubble nucleation and bubble growth. A second component of this model captures the low gas mobility in heavy oil reservoirs and its dependency on viscous forces. To account for the effect of viscous forces on gas mobility, the proposed relative permeability function depends not only on gas saturation but also on local oil phase velocity and oil viscosity. While many of the previously existing models apply several kinetic equations associated with a large number of parameters, it has been shown that the modifications suggested in this study enable predicting many of the unusual behaviours observed in solution-gas drive in heavy oil reservoirs, using only one kinetic equation with a smaller number of fitting parameters.
Debugger-driven Embedded Fuzzing

description: Embedded Systems – the hidden computers in our lives – are deployed in the billionths and are already in the focus of attackers. They pose security risks when not tested and maintained thoroughly. In recent years, fuzzing has become a promising technique for automated security testing of programs, which can generate tons of test inputs for a program. Fuzzing is hardly applied to embedded systems, because of their high diversity and closed character. During my research I want tackle that gap in fuzzing embedded systems – short: “Embedded Fuzzing”. My goal is to obtain insights of the embedded system during execution, by using common debugging interfaces and hardware breakpoints to enable guided fuzzing in a generic and widely applicable way. Debugging interfaces and hardware breakpoints are available for most common microcontrollers, generating a potential industry impact. Preliminary results show that the approach covers basic blocks faster than blackbox fuzzing. Additionally, it is source code agnostic and leaves the embedded firmware unaltered.

description: The endocrine control of the reproductive function is often studied from the analysis of luteinizing hormone (LH) pulsatile secretion by the pituitary gland. Whereas measurements in the cavernous sinus cumulate anatomical and technical difficulties, LH levels can be easily assessed from jugular blood. However, plasma levels result from a convolution process due to clearance effects when LH enters the general circulation. Simultaneous measurements comparing LH levels in the cavernous sinus and jugular blood have revealed clear differences in the pulse shape, the amplitude and the baseline. Besides, experimental sampling occurs at a relatively low frequency (typically every 10 min) with respect to LH highest frequency release (one pulse per hour) and the resulting LH measurements are noised by both experimental and assay errors. As a result, the pattern of plasma LH may be not so clearly pulsatile. Yet, reliable information on the InterPulse Intervals (IPI) is a prerequisite to study precisely the steroid feedback exerted on the pituitary level. Hence, there is a real need for robust IPI detection algorithms. In this article, we present an algorithm for the monitoring of LH pulse frequency, basing ourselves both on the available endocrinological knowledge on LH pulse (shape and duration with respect to the frequency regime) and synthetic LH data generated by a simple model. We make use of synthetic data to make clear some basic notions underlying our algorithmic choices. We focus on explaining how the process of sampling affects drastically the original pattern of secretion, and especially the amplitude of the detectable pulses. We then describe the algorithm in details and perform it on different sets of both synthetic and experimental LH time series. We further comment on how to diagnose possible outliers from the series of IPIs which is the main output of the algorithm.

description: We study the Kane-Mele-Hubbard model both at half-filling and away from half-filling using a slave-boson mean-field approach at zero temperature. We obtain a phase diagram at half-filling and discuss its connection to recent results from quantum Monte Carlo, slave-rotor, and $Z_2$ mean-field studies. In particular, we find a small window in parameter space where a spin liquid phase with gapped spin and charge excitations reside. Upon doping, we show the spin liquid state becomes a superconducting state by explicitly calculating the singlet pairing order parameters. Interestingly, we find an "optimal" doping for such superconductivity. Our work reveals some of the phenomenology associated with doping an interacting system with strong spin-orbit coupling.
