description: While there are many stones on which to step between "stunt pastors" and "a culture of Christianity that does not encourage thought," pressure against thoughtfulness has deep roots in American culture, particularly American religion. To his credit and to the benefit of the Christian church, Christopher Morse taught in such a way that his students who became pastors were inspired and trained to offer an alternative to this deeply-rooted historical pressure.

description: Currently, there is no cure for dementia and prevention trials need to be redesigned with a focus on high-risk population and standardized biomarkers, which include clinical, demographic, imaging and neuropsychological considerations. Transient Ischemic Attack (TIA) patients are at an increased risk of dementia due to the presence of vascular risk factors and underlying vascular/neurodegenerative pathology. We hypothesized that at baseline TIA patients will exhibit abnormal microstructural white matter (WM) changes as measured by diffusion tensor imaging (DTI) parameters, and that these parameters will predict worse cognitive outcomes. Our results suggest that TIA patients showed higher axial diffusivity (AxD), mean diffusivity (MD) and radial diffusivity (RD) parameters in the fornix, a tract crucial for memory, and lower fractional anisotropy (FA) overall when compared to healthy controls. TIA patients also performed poorer on tests of executive function, episodic and working memory, and processing speed. DTI parameters of FA and MD predicted performance in tests of executive function and memory but not processing speed. Considering these results, TIA patients are a high-risk population for cognitive change.

description: The concept of "quantum stress (QS)" is introduced and formulated within density functional theory (DFT), to elucidate extrinsic electronic effects on the stress state of solids and thin films in the absence of lattice strain. A formal expression of QS (σ^Q) is derived in relation to deformation potential of electronic states (Ξ) and variation of electron density (Δn), σ^Q = ΞΔn, as a quantum analog of classical Hook's law. Two distinct QS manifestations are demonstrated quantitatively by DFT calculations: (1) in the form of bulk stress induced by charge carriers; and (2) in the form of surface stress induced by quantum confinement. Implications of QS in some physical phenomena are discussed to underlie its importance.

Although direct reference to the work of the New Testament scholar, J. Louis Martyn, is made frequently throughout the address, the influence of Christopher Morse also stands behind everything I say about the significance of apocalyptic for theology and Christian ethics. Christopher was my advisor in the Ph.D. program in Systematic Theology at Union Theological Seminary, starting in 1979, and continues to be my mentor and friend as well as conversation partner regarding all things apocalyptic.

description: The intestinal epithelium is covered with a thick viscous MUC2 mucin bilayer that acts as a protective barrier and is the habitat for 1014 microorganisms that form the microbiota. Even though disruption of colonic mucus and alterations in microbial composition are intimately linked to gastrointestinal health and disease, their distinct contribution in the pathogenesis of colonic injury is not well understood. In this thesis, I interrogated the impact of alterations in the microbial composition in animals with and without Muc2 mucus in colonic epithelial barrier dysfunction and inflammation, using chemical and pathogen-induced colitis models. For all studies Muc2+/+ and Muc2+/+ littermates were used to normalize the microbiota. To induce dysbiosis (alterations in microbial composition) and reduce bacterial numbers, mice were treated with a broad-spectrum cocktail of antibiotics. Basally, Muc2-/- littermates showed low-grade ongoing inflammation, gastrointestinal permeability and alterations in tight junction proteins that were restored after antibiotic treatment. Muc2+/+ microbiota had a protective innate role against DSS-induced colitis, while microbiota from Muc2 deficient animals did not. Muc2+/+littermates that received Muc2-/- microbiota exhibited a shift in bacteria families and increased susceptibility to DSS and Citrobacter rodentium-induced colitis, demonstrating a critical role for Muc2 mucus in shaping a healthy microbiota in intestinal homeostasis. I also investigated the interdependent relationship between the mucus layer and colonic microbiota in Entamoeba histolytica (Eh)-induced secretory and inflammatory responses, using Muc2-/- and Muc2+/+ littermates and germ-free mice. Following microbial disruption with antibiotics, Eh elicited increased water and mucus secretions and enhanced pro-inflammatory responses. Eh also dysregulated the transcription factor for secretory goblet cells, Math1, which was microbiota dependent. Germ-free mice showed decrease pro-inflammatory and mucus secretagogue responses towards Eh, demonstrating that commensal microbiota plays an important role in mediating host protection against Eh and that dysbiosis can render the colonic epithelium susceptible to Eh-induced pro-inflammatory responses and tissue injury. These findings unravel the interconnected role of a healthy Muc2 barrier and commensal microbiota in maintaining intestinal innate host defense against colonic injury.

description: The distribution of capture zones formed during the nucleation and growth of point islands on a one-dimensional substrate during monomer deposition is considered for general critical island size $i$. A fragmentation theory approach yields the small and (for $i=0$) large size asymptotics for the capture zone distribution (CZD) under the assumption of no neighbour-neighbour gap size correlation. These CZD asymptotic forms are different to those of the Generalised Wigner Surmise which has recently been proposed for island nucleation and growth models, and we discuss the reasons for the discrepancies.

description: The Congress of Women developed a roadmap for enduring peace. The women passed 20 resolutions including five resolutions which were “Principles of a Permanent Peace.” Theirs was a gendered response to a gendered war. The Congress was a bold and brave initiative. The war was not halted. But neither were the women in their quest for peace. This is their story.
description: The International Congress of Women was the major peace initiative of its day. The stakes were high, the odds were low. During the blood-letting of World War 1 (1914-1918), over a thousand women joined together to stop the war. The women came from neutral countries, from belligerent countries of both the Entente and the Central Powers, and from invaded Belgium. These women put their differences - and safety - aside and assembled at The Hague in 1915 (28 April to 1 May).

SPHS: Smoothed Particle Hydrodynamics with a higher order dissipation switch

description: We present a novel implementation of Smoothed Particle Hydrodynamics (SPHS) that uses the spatial derivative of the velocity divergence as a higher order dissipation switch. Our switch -- which is second order accurate -- detects flow convergence before it occurs. If particle trajectories are going to cross, we switch on the usual SPH artificial viscosity, as well as conservative dissipation in all advected fluid quantities (for example, the entropy). The viscosity and dissipation terms (that are numerical errors) are designed to ensure that all fluid quantities remain single-valued as particles approach one another, to respect conservation laws, and to vanish on a given physical scale as the resolution is increased. SPHS alleviates a number of known problems with `classic' SPH, successfully resolving mixing, and recovering numerical convergence with increasing resolution. An additional key advantage is that -- treating the particle mass similarly to the entropy -- we are able to use multimass particles, giving significantly improved control over the refinement strategy. We present a wide range of code tests including the Sod shock tube, Sedov-Taylor blast wave, Kelvin-Helmholtz Instability, the `blob test', and some convergence tests. Our method performs well on all tests, giving good agreement with analytic expectations.

description: In this paper I use the interpretation of the repetitive adverb opjat’ ‘again’ in Rus-

sian to argue that ditransitive structures in this language do not involve a small

clause structure (Kayne 1984; Beck & Johnson 2004; a.o.). Under the syntactic ap-

proach to the semantics of repetitives that I adopt (von Stechow 1996; Beck 2005;

a.o.), the interpretation of repetitives is determined by their attachment in the syn-

tactic representation. I show that in Russian ditransitives, unlike in English ones

(Beck & Johnson 2004), only the repetitive reading of ‘again’ is possible, and argue

that no reason other than a difference in the syntactic structures of ditransitives

in two languages can account for that. I also observe that unlike datives that are

found in ditransitives, “higher” dative arguments and locative applicatives in Rus-

sian can occur in constructions where there is a syntactic constituent denoting the

resultant state, and thus the restitutive reading of repetitives is available.

description: Though much has been rightly made of the destruction wrought by the oil spill in the Gulf of Mexico in April, 2010, it pales in comparison to the ongoing damage done to the environment by our unsustainable way of life. Global instability exacerbated by the economic crisis of 2008 to the present has compounded increasing ecological vulnerabilities, including the most basic needs of food and water among the world’s poorest. Because of these combined crises, it is vital that people of faith develop methods of collaboration that support and enrich each others' efforts towards sustainability sooner rather than later. Given the extent and magnitude of our economic and environmental problems, it is time for evangelicals and liberal Protestants to work together for the ecological good. Protestantism has been a religious movement for great good, but also the source of deep divisions. Born through a division with the Roman Catholic Church, Protestantism, in its engagement with modernity, forced a further division into evangelical and liberal communities. Now the urgent need to preserve and regenerate the global environment offers an ideal opportunity to work towards the repair of these older theological divisions through joining together in the common task of environment justice. In seeking to repair the earth as a common ethical task, Protestants can also enact an ecumenical vocation to heal the divisions within the broader world Christian movement.

description: The spectral energy distribution (SED) of a galaxy contains information on the galaxy's physical properties, and multi-wavelength observations are needed in order to measure these properties via SED fitting. In planning these surveys, optimization of the resources is essential. The Fisher Matrix formalism can be used to quickly determine the best possible experimental setup to achieve the desired constraints on the SED fitting parameters. However, because it relies on the assumption of a Gaussian likelihood function, it is in general less accurate than other slower techniques that reconstruct the probability distribution function (PDF) from the direct comparison between models and data. We compare the uncertainties on SED fitting parameters predicted by the Fisher Matrix to the ones obtained using the more thorough PDF fitting techniques. We use both simulated spectra and real data, and consider a large variety of target galaxies differing in redshift, mass, age, star formation history, dust content, and wavelength coverage. We find that the uncertainties reported by the two methods agree within a factor of two in the vast majority (~ 90%) of cases. If the age determination is uncertain, the top-hat prior in age used in PDF fitting to prevent each galaxy from being older than the Universe needs to be incorporated in the Fisher Matrix, at least approximately, before the two methods can be properly compared. We conclude that the Fisher Matrix is a useful tool for astronomical survey design.

description: On October 23, 2011, Judith Butler joined the ranks of public intellectuals to come out in support of Occupy Wall Street – an ensemble that has included Slavoj Žižek and Cornel West, not to mention the next-gen radical anthropologist David Graeber, who was an early participant in the New York occupation. Butler’s articulation of principles during a General Assembly at Washington Square Park spoke to an internal tension within activist rhetoric that predates the recent groundswell of popular anti-capitalism. Whether ostensibly critical or sympathetic, the interpretive framework for engaging radical organizing appears bifurcated and based on a false dichotomy of activist stereotypes that have even become hot commodities in the marketing world now that protest is fashionable again – as comically exemplified by Axe Body Spray’s ludicrous marketing campaign to peddle its new scent, "Anarchy." Whether dismissively depicting the protestors as quasi-eschatological millennial idealists (even the atheists) or bewildered, angst-ridden Holden Caulfield impostors who compulsively rally against something without contributing anything constructively to society, both renderings infantilize their subjects, because they are both escapist, and ignore the murky realities of day-to-day necessity and the work involved in building and maintaining a homeostatic social order.

description: Silver (I) is an antimicrobial agent that has established antimicrobial activity, yet the mechanism of action is unclear. This thesis follows up on an observation that Ag+ ions cause the cell membrane to separate from the cell wall in Escherichia coli. Data from a chemical genomic screen was utilized, identifying 6 Ag-responsive cells with single gene deletions (damX, rodZ, minC, sanA, ybhO, tolB), which are genes involved in maintenance of the cell envelope. When these mutants were grown in the presence of Ag+, cells demonstrated extensive cell envelope damage as seen by transmission electron microscopy. Evaluation of kill curves, some mutants conferred resistance and others sensitivity to silver in comparison to wildtype. From the data collected, it was recognized that functions around cell wall and transport across the cell membranes have roles in both silver resistance and sensitivity.
Investigating speed-accident relationship at urban signalized intersections using accident prediction models
Creators: name: Tian, Zhun
Publisher: name: University of British Columbia
Year: 2011

description: Motor vehicle speed is a key risk factor contributing to many road accidents. Historical data shows that speed-related accidents account for a significant proportion of all the fatal and serious injury accidents and result in considerable social and economic costs. The objective of this thesis is to understand and quantify the relationship between traffic speed and accident frequency at urban signalized intersections in the city of Edmonton and Vancouver, Canada. This objective is achieved by developing accident prediction models which relate accident frequency to speed variables and other intersection characteristics. Road accident, traffic speed, traffic flow and road geometric data were obtained from the two cities for the purpose of the models development. The generalized linear modelling techniques are used to develop the accident prediction models assuming negative binomial error structure. A total of 15 models are developed relating accident frequency with five speed variables: average speed, mode speed, 85th percentile speed, speed standard deviation and percent of vehicles speeding. The results show that all five speed variables are positively correlated with accident frequency. A quantitative relationship between the change in the value of speed variables and the change in accident frequency is derived from the developed models.

description: A good evaluation of transport properties in reservoir rocks plays a major role in the design of recovery process and prediction of recovery performance. Permeability, thermal and electrical conductivity, are important physical properties affecting fluid flow and fluid distribution. Numerical techniques based on image analysis can be considered as reliable alternative approaches to either experimental methods or empirical correlations to estimate petrophysical properties. There are various numerical approaches to directly simulate fluid flow through a virtual porous medium. For instance, Computational Fluid Dynamics (CFD) and Lattice-Boltzmann as dynamic methods, and pore morphological as quasi-static approaches are the most popular techniques to simulate flow through porous materials. A virtual porous medium can be provided by binarizing either the real CT scan images of porous media or even the synthetic images generated by statistical approaches. In this regard, the virtual porous media have to properly mimic the physical features of real sands. As providing real CT scan images with high-resolution of rock samples is expensive and time consuming, utilizing statistical approaches to generating synthetic porous media based on Particle Size Distribution (PSD) and porosity of real sands could be considered as an alternative to reconstruct virtual porous media. To generate a virtual porous medium statistically, an innovative algorithm is proposed in this research generating irregular grains based on a given porosity and particle size distribution (PSD). The proposed procedure is inspired from the crystallization concept. In this method, the shape, orientation and structure of the grains can be readily controlled by the user. This provides the opportunity to investigate the effect of some geometrical parameters such as grain irregularity on rock and flow properties. In this study, several virtual porous media with different porosities, sphericities and PSD are constructed using the proposed approach. Based on the simulation results on these media the effect of grain irregularity on transport properties and onset of non-Darcy flow is investigated.

description: A handful of studies have recently emerged dealing with Mormonism, its unique set of authoritative texts, and the topic of homosexuality. Some seek to demonstrate how Mormonism might imagine new or alternative theological positions in the Church by deconstructing dominant Latter-day Saint theologies and the verses of scripture that shape them. Specifically, two come to mind (among a handful of examples): Taylor Petrey has written an article titled "Toward a Post-Heterosexual Mormon Theology," which was recently published in Dialogue: A Journal of Mormon Thought. In another instance, Seth Payne has written an essay titled "Mormonism and Same-Sex Marriage: Towards a Mormon Theology of Gender," forthcoming through the Journal of Catholic Legal Studies. What has not been attempted, to my knowledge, is a work that deals with the "everyday theologies" of LGBTQ Latter-day Saints, their families/allies, and those who defend more traditional theological (and political) positions.

description: A key architectural element of future quantum photonic networks is an efficient light-matter interface to connect electronic and photonic qubit systems. Nanophotonic resonators can be fabricated on-chip to provide such interfaces for atomic-like defect centers in diamond, which are leading qubit candidates. Fabrication advancements have recently lead to the construction of high quality diamond microdisk resonators, which show potential to reach enhancements with Purcell factor CNV ∼ 50. Here, a room-temperature experimental apparatus integrating free space and visible wavelength fiber-taper measurement capabilities is built to characterize diamond microdisk resonators. Using this setup, microdisk wisphering gallery modes with quality factors at visible wavelengths resonant with defect centers as high as Q ∼ 1 × 105, are observed for the first time. Spectral filtering effects of the taper on the microdisk are analysed to reveal that coupling to these disks may be limited by phase matching requirements. By thinning these disks it should be possible to improve coupling while lowering mode volumes, as desired to optimize Purcell factors.

description: The differences between the neutron-capture element abundances of halo stars are important to our understanding of the nucleosynthesis of elements heavier than the iron group. We present a detailed abundance analysis of carbon and twelve neutron-capture elements from Sr up to Pb for a peculiar halo star G24-25 with [Fe/H] = -1.4 in order to probe its origin. The equivalent widths of unblended lines are measured from high resolution NOT/FIES spectra and used to derive abundances based on Kurucz model atmospheres. In the case of CH, Pr, Eu, Gd, and Pb lines, the abundances are derived by fitting synthetic profiles to the observed spectra. Abundance analyses are performed both relative to the Sun and to a normal halo star G16-20 that has similar stellar parameters as G24-25. We find that G24-25 is a halo subgiant star with an unseen component. It has large overabundances of carbon and heavy s-process elements and mild overabundances of Eu and light s-process elements. This abundance distribution is consistent with that of a typical CH giant. The abundance pattern can be explained by mass transfer from a former asymptotic giant branch component, which is now a white dwarf.

title: A thousand intertwinings: an exploration of embodied artistic processes made in collaboration with an estuarine landscape and its vibrant matter
Creators: name: Halcrow, L
Publisher: name: Bath Spa University
Year: 2022

description: This doctoral research project is practice-based, artistic research. It proceeds through the development of a series of explorations of embodied, sensorial processes and emergent artworks made in collaboration with place, its materiality, entangled more-than-human and non-human worlds through the often-overlooked stuff of the everyday; from the earth underfoot, to human debris in the form of abandoned structures, daily washed-up plastic and discarded metal detritus. These artworks are thought of as "matter maps" with the embodied making as experimental re-mapping activities. The project asks the question: "How can slow and collaborative artistic mapping processes generate careful records through touch and a close engagement with the vibrant matter of 'place'?" The artistic work/processes as "matter maps" are framed through contextual writing that aims not to replace the work with words, but to offer insights through the lens of Karen Barad's 'agential realism', exploring entangled intra-actions with matter (2007); Donna Haraway's diffractive exploration of matter as a mode of 'making kin' (2016); and Jane Bennett's 'vibrant matter' and 'thing-power' (2010). Contemporary writers including David Abram, Edward Casey, Gilles Deleuze, Tim Ingold, Brian Massumi, Maria Puig de la Bellacasa, Isabelle Stengers, and Rebecca Solnit will provide additional contextual insights in relation to care, embodiment, slow attunement, repetition, horizontal ontologies and the anarchive. Writers exploring contemporary artists working with place, materiality, trace and mapping are highlighted to attend to current trans-disciplinary discourse and artistic research within this field. The project is the culmination of six years of frequent walks along the Taw Estuary in North Devon (UK), so this place in particular forms a case study. The emergent artworks are often fragile or in a state of flux, working with approaches to mapping human, non-human and more-than-human traces situated within a counter-cartographical framework (Stephanie Springgay and Sarah Truman, 2018). This approach aims to unsettle the embodied experience of walking in a place through the act of slowing down to form a close tuning into its matter, and to disrupt notions around what is mapped, how it is mapped, by whom and for what purpose. In this way the work and the contextual writing explores multiple strands that weave together and meander in forms that echo the experience of walking, the estuary itself and my childhood memories of this place. All are inextricably entangled with my experience of the Taw, the residue of the estuary on my walking body, and the trace of my body within the estuary.
Physical and Numerical Modelling of Pipelines in Elastic Visco-Plastic Soils Under Long-Term Ground Movements

description: Pipelines have been constructed and designed to transport essential natural resources such as water, oil, and natural gas for the last 160 years. Many pipeline sections built are buried at shallow depths below the ground surface and through different geologic terrains. This includes complex terrains where permanent ground deformations can occur such as moving slopes/landslides, surface faulting, and ground subsidence. Pipeline sections subjected to such permanent ground deformations can yield because of large strain accumulation over time leading to large pipe stresses. The mode of pipe yielding promoted by permanent ground deformations is dependent on the pipeline axis orientation with respect to the ground movement direction. Longitudinal ground movements promote pipe buckling, transverse ground movements promote pipe bending, and complex ground movements promote a mix of pipe bending and buckling. This study introduces a set of numerical tools aimed at predicting the soil movement before a buried pipeline section reaches the onset of yielding. Various numerical tools are developed for pipelines buried in compacted clay soils such as Regina clay. Compacted clay soils are of specific interest as they exhibit significant time-dependent behavior such as creep, constant strain rate effect, and stress relaxation. The main benefit of the numerical tools developed in this thesis is for the pipeline industry to be able to continually assess pipeline performance in areas with unstable soil movements and to perform necessary remediation procedures such as pipe stress relief to prolong pipeline operation at the right time. The three phases of numerical tool development include: 1) Determination of constitutive models for compacted Regina clay and soil-pipe interface, 2) Validation of the longitudinal, transverse and vertical uplift soil resistances in existing buried pipeline guidelines through a series of physical soil-pipe prototype tests, and 3) Validation of the physical prototype test results through the creation of an Extended Finite Element Method (XFEM) numerical model. The physical prototype test results illustrate consistency with existing guidelines for transverse horizontal soil resistances, but a discrepancy for vertical uplift soil resistances. There also exists behavior discrepancy in the longitudinal soil resistances. The discrepancy in vertical pipe uplift results arises from neglecting the tensile failure mode of the soil in the guidelines. The behavior discrepancy in longitudinal loading is due to differences in adhesion factor estimation, also neglected in the guidelines. The final XFEM numerical model with cap (modified Drucker-Prager) plasticity coupled with Singh-Mitchell creep law for Regina clay demonstrate good predictions of soil-pipe interactions from physical prototype tests.

Matthew 11:28-29 When I was a child, I said the same bedtime prayer every night: "Jesus, meek and humble of heart, make my heart like unto thine." I don’t recall ever thinking about the words of the prayer, or understanding exactly why I would want a "humble heart." It is only now, decades later, that I have given considerable thought to what a "humble heart" might be. My interest in the oft misunderstood virtue of humility was sparked by the work I do at the Center for the Study of Science and Religion (CSSR) at the Earth Institute of Columbia University. My colleagues at the CSSR who are microbiologists, ecologists, cosmologists, and primatologists have clearly shown me that the natural sciences have much to teach theologians about humility.

description: Recently, an excess of events consistent with a Higgs boson with mass of about 125 GeV was reported by the CMS and ATLAS experiments. This Higgs boson mass is consistent with the values that may be obtained in minimal supersymmetric extensions of the Standard Model (SM), with both stop masses less than a TeV and large mixing. The apparently enhanced photon production rate associated with this potential Higgs signal may be the result of light staus with large mixing. Large stau mixing and large coupling of the staus to the SM-like Higgs boson may be obtained for large values of tan β, and moderate to large values of the Higgsino mass parameter, μ. We study the phenomenological properties of this scenario, including precision electroweak data, the muon anomalous magnetic moment, Dark Matter, and the evolution of the soft supersymmetry-breaking parameters to high energies. We also analyze the possible collider signatures of light third generation sleptons and demonstrate that it is possible to find evidence of their production at the 8 TeV and the 14 TeV LHC. The most promising channel is stau and tau sneutrino associated production, with the sneutrino decaying into a W boson plus a light stau.

title: Meme - a novel & In search of digital gothic
Creators: name: Teasdale, B
Publisher: name: Bath Spa University
Year: 2022

description: This doctoral thesis comprises a novel, Meme, which I consider to be in the new genre of digital gothic, and a piece of contextualising research, In Search of Digital Gothic. Meme tells the story of Scarlett, a PhD student in Digital Anthropology who stumbles across the existence of an ancient folk tale that is so disturbing, frightening or dangerous that it has always been forbidden from being shared. Scarlett comes to believe that the tale was leaked onto the internet, and sets out to track it down. In doing so, she discovers it may have played a role in the death of her brother Nathan, whose suicide some years before has left her traumatised and unable to connect with the world around her. In my contextualising research, I explain how I was drawn to the "digital gothic" as a way to express the sense that, beneath the perfect sheen of our twenty-first-century digitally mediated lives, there are troubling and ambiguous forces that border on the uncanny. The Gothic as a genre is a natural correlative or container for such ideas, and my project explores existing manifestations of the digital gothic in both prose fiction and multimedia works. In Part II, "Infectious Media", I examine the behaviour of 'memes', and analyse their unsettling features as 'uncanny replicators' that display 'uncanny metalepsis'. I draw comparisons with Bram Stoker's Dracula (1897), arguing that Dracula is in essence -a meme; and with the ghost stories of M.R. James, in particular "The Mezzotint" (1904), where multimedia objects repeatedly breach their protective frames. Part Ill, "Digital Masks, Digital Ghosts", explores 'presence' in the digital age, with a focus on the haunting possibilities inherent in social media and communications, anonymity and trolling. I use the recent cinematic subgenre of webcam horror (Unfriended, Cam, Host) to examine the notion of the digital ghost. Finally, in Part IV, "Haunted Mazes", I discuss the manifestation of 'uncanny time' and 'interactivity' in the digital gothic, utilising the metaphor of the maze or labyrinth. I use the Jacques Derrida/Mark Fisher concept of 'hauntology' as a frame to examine these themes in the M. R. James ghost story "Mr Humphreys and his Inheritance" (1911), and Charlie Brooker's interactive television episode, Black Mirror: Bandersnatch (2018). Taken together, the novel and the contextual research offer an innovative creative­critical undertaking that nonetheless draws upon an existing tradition of literary work, and resonates meaningfully with the wider culture beyond it.
Effect of surface micro- and nanolayers of composite particles on thermoelectric figure of merit (phenomenological approach)

description: Non-symmetric variants of self-consistent field theory are proposed that served the basis for theoretical investigation of the effect of thermal conductivity of composite particles surface layers on the effective thermoelectric figure of merit. It is shown that in some cases thermoelectric figure of merit can be essentially improved due to the presence of a shell.
Effect of aspect-ratio on vortex distribution and heat transfer in rotating Rayleigh-Bénard convection

description: Numerical and experimental data for the heat transfer as function of the Rossby number Ro in turbulent rotating Rayleigh-Bénard convection are presented for Prandtl number Pr=4.38 and Rayleigh number $Ra=2.91\times10^8$ up to $Ra=4.52\times10^9$. The aspect ratio Γ= D/L, where L is the height and D the diameter of the cylindrical sample, is varied between Γ=0.5 and Γ=2.0. Without rotation, where the aspect ratio influences the global large scale circulation, we see a small aspect-ratio dependence in the Nusselt number for $Ra=2.91\times10^8$. However, for stronger rotation, i.e. $1/Ro \gg 1/Ro_c$, the heat transport becomes independent of the aspect-ratio. We interpret this finding as follows: In the rotating regime the heat is mainly transported by vertically-aligned vortices. Since the vertically-aligned vortices are local, the aspect ratio has a negligible effect on the heat transport in the rotating regime. Indeed, a detailed analysis of vortex statistics shows that the fraction of the horizontal area that is covered by vortices is independent of the aspect ratio when $1/Ro \gg 1/Ro_c$. In agreement with the results of Weiss et al. Phys. Rev. Lett., vol 105, 224501 (2010) we find a vortex-depleted area close to the sidewall. Here, we in addition show that there is also an area with enhanced vortex concentration next to the vortex-depleted edge region and that the absolute widths of both regions are independent of the aspect ratio.

Polarization Controlled Coherent Anti-Stokes Raman Scattering Microscopy for Determination of Structural Order of the Myelin Sheath

description: Coherent Anti-Stokes Raman Scattering (CARS) is a laser-scanning microscopy technique that generates a strong label-free signal in lipid. The myelin sheath surrounding nerves is up to 80% lipid, and therefore is an ideal candidate for CARS imaging. The long lipid chains forming the myelin wraps have a directional preference when the myelin is healthy, with CH2 bonds aligned parallel to the axis of the nerve. The optical polarization dependence of the CARS signal can be used to probe the orientation of CH2 bonds in the sheath and determine their nanoscopic orientation. As myelin becomes unhealthy the organization of the lipids begins to loosen from their native organized packing structure. In the early stages this is not visible by conventional microscopy, however polarization-resolved CARS can measure the increasing disorder in the arrangement of the bonds before obvious morphological changes can occur. The degree of disorder is also measured to provide a metric of myelin disorganization in disease models.
