description: Consider the Schroeodinger equation: - Du(x) - l(x)u + s(x)u = 0, where D is the Laplacian, l(x) > 0 and s(x) is dominated by l(x). We shall extend the celebrated Kato's result on the asymptotic behavior of the solution to the case where l(x) has unbounded discontinuity. The result will be used to establish the limiting absorption principle for a class of reduced wave operators with discontinuous coefficients.

Neville Lytton, the Balcombe frescoes and the experience of war, 1908-1923
Creators: name: Grieves, Keith

description: Sussex Archaeological Collections, 134, 197-211
description: The Hon. Neville Lytton of Crabbet Park and the Royal Sussex Regiment left much evidence of a reflective approach to the impact of the First World War on his life as a squire. In 1914 his leisured lifestyle was overtaken by the age old function of the landed gentleman in war which was to go to the Front at the head of his tenantry. In 1916 substantial portions of the Crabbet estate were sold and in Worth the association of locality and controlling landowner abruptly diminished while he served in a front-line unit during the Somme offensive. In France, Lytton grew to appreciate the essential role and virtues of the 'common man' and to understand that his advance would bring an end to squires and their 'kingdoms '. After the war he revealed himself as an acute observer of the impact of war on the 'South Country' landed elite. Lytton also contributed to the memorial hall movement by undertaking War and Peace frescoes at the Victory Hall, Balcombe in 1923. He visualized a village community which was not dependent on the country house and celebrated the natural beauty of the Sussex landscape. As an artist-memorialist of the Great War, who had served in a locally-raised battalion, Lytton provided as much insight as Edmund Blunden into the effect of total war on the pastorally-minded.

description: Formulae expressing the trace of the composition of several (up to five) adjoint actions of elements of the Griess algebra of a vertex operator algebra are derived under certain assumptions on the action of the automorphism group. They coincide, when applied to the moonshine module $V^\natural$, with the trace formulae obtained in a different way by S.Norton, and the spectrum of idempotents related to 2A, 2B, 3A and 4A element of the Monster is determined by the representation theory of Virasoro algebra at $c=1/2$, $W_3$ algebra at $c=4/5$ or $W_4$ algebra at $c=1$. The generalization to the trace function on the whole space is also given for the composition of two adjoint actions, which can be used to compute the McKay-Thompson series for a 2A involution of the Monster.

description: Constraints on the tension and the abundance of cosmic strings depend crucially on the rate at which they decay into particles and gravitational radiation. We study the decay of cosmic string loops in the Abelian-Higgs model by performing field theory simulations of loop formation and evolution. We find that our set of string loops emit particle radiation primarily due to kink collisions, and that their decay time due to these losses is proportional to $L^p$ with $p \approx 2$ where $L$ is the loop length. In contrast, the decay time to gravitational radiation scales in proportion to $L$, and we conclude that particle emission is the primary energy loss mechanism for loops smaller than a critical length scale, while gravitational losses dominate for larger loops.

description: Trilayer nickelates, which exhibit a high degree of orbital polarization combined with an electron count (d8.67) corresponding to overdoped cuprates, have been identified as a promising candidate platform for achieving high-Tc superconductivity. One such material, La4Ni3O8, undergoes a semiconductor-insulator transition at ~105 K, which was recently shown to arise from the formation of charge stripes. However, an outstanding issue has been the origin of an anomaly in the magnetic susceptibility at the transition and whether it signifies formation of spin stripes akin to single layer nickelates. Here we report single crystal neutron diffraction measurements (both polarized and unpolarized) that establish that the ground state is indeed magnetic. The ordering is modeled as antiferromagnetic spin stripes that are commensurate with the charge stripes, the magnetic ordering occurring in individual trilayers that are essentially uncorrelated along the crystallographic c-axis. Comparison of the charge and spin stripe order parameters reveals that, in contrast to single-layer nickelates such as La2-xSrxNiO4 as well as related quasi-2D oxides including manganites, cobaltates, and cuprates, these orders uniquely appear simultaneously, thus demonstrating a stronger coupling between spin and charge than in these related low-dimensional correlated oxides.

description: We investigate the occurrence and nature of naked singularities in the Szekeres space-times. These space-times represent irrotational dust. They do not have any Killing vectors and they are generalisations of the Tolman-Bondi-Lemaitre space-times. It is shown that in these space-times there exist naked singularities that satisfy both the limiting focusing condition and the strong limiting focusing condition. The implications of this result for the cosmic censorship hypothesis are discussed.

Furthermore, the overlaps satisfy ultrametric relations. As a consequence the Parisi tree is essentially the same at all temperatures with lower branches developing when lowering the temperature. We conjecture that the reference free energies of the clusters are also fixed at all temperatures as in the generalized random-energy model.

description: Professional development is a continuous process of individual and experimental tests that must empower individual educators to make complex decisions; to identify and to solve problems; to connect theory and practice in learners’ output; and to enable educators to offer learning opportunities to students and prepare them in terms of provided world class standards and citizen responsibilities of adults inspired by these assumptions, the present study aimed to identify factors affecting the professional development of its faculty members. The statistical sample consisted of 209 individuals all of whom were faculty members of the Islamic Azad University, Ilam Branch, Iran that were studied by a census method. The survey instrument was a research-made questionnaire whose content and face validity was confirmed by a panel of experts and its reliability coefficient turned out to be at a desirable level. SPSS21 software and factor analysis technique were employed to analyze the collected data. The results of the factor analysis showed that four development services such as structural-service maturity, institutional directorial maturity, personal and character maturity and network-social maturity were identified as factors affecting the professional development of faculty members which explained 50.89% of the total variance altogether.

description: Countries need short, medium, and long-term investment plans for production growth and development. Different sources for these investments can be supplied through retained profit, stock issuance, and bank loans, or a combination them. Institutions and firms need huge amount of capitals for their survival, production, and also development of activities. In addition, these institutions and firms rely heavily on financial markets for self-financing. The role of financial markets is to provide the required capitals for institutions and firms. Financing strategy is considered as one of the main areas of financial management decisions in companies seeking to increase shareholders’ wealth. Therefore, the aim of this paper was to discuss conventional methods of external financing through debt and stock issuance and explain their associated advantages and disadvantages.
Introduction to Dynamic Linear Models for Time Series Analysis
Creators: name: Laine, Marko
Publisher: name: arXiv
Year: 2019
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: Dynamic linear models (DLM) offer a very generic framework to analyse time series data. Many classical time series models can be formulated as DLMs, including ARMA models and standard multiple linear regression models. The models can be seen as general regression models where the coefficients can vary in time. In addition, they allow for a state space representation and a formulation as hierarchical statistical models, which in turn is the key for efficient estimation by Kalman formulas and by Markov chain Monte Carlo (MCMC) methods. A dynamic linear model can handle non-stationary processes, missing values and non-uniform sampling as well as observations with varying accuracies. This chapter gives an introduction to DLM and shows how to build various useful models for analysing trends and other sources of variability in geodetic time series.

Networks of Displacement Genealogy, Nationality, and Ambivalence in Works by Vladimir Nabokov and Gary Shteyngart

description: In this dissertation I examine Vladimir Nabokov’s and Gary Shteyngart’s use of family metaphors to manage intersecting Russian and American literary and cultural continuities.  Both authors fashion their relationships to literary predecessors and common cultural narratives in terms of disrupted filial relationships, describing both an attachment to the conservative narratives of the nation and a desire to move beyond their rigid structure.  I articulate this ambivalence as a productive state of transnational subjecthood that allows these authors to navigate apparently oppositional national identities.  Central to this reorientation is a critique of the hierarchical schema of the national canon, which frames literary culture as a determinative series of authoritative relationships.  By reimagining these relations as part of a branching network of co-constituting associations, we open the space for transnational subjects to move within and overlap these networks.

description: Thermodynamic uncertainty relations have emerged as universal bounds on current fluctuations in non-equilibrium systems. Here we derive a new bound for a particular class of run-and-tumble type processes using the mathematical framework of renewal-reward theory which can be applied to both Markovian and non-Markovian systems. We demonstrate the results for selected single-particle models as well as a variant of the asymmetric simple exclusion process with collective tumbles. Our bound is relatively tight for a broad parameter regime and only requires knowledge of the statistics of run lengths and the mean entropy production rate of tumbles.

description: Using data from previous cohorts of Curtin students, our research team have developed a program called Checking on Mental Health Providing Alternatives to Suicide for Students (COMPAS-S). The team have developed a multivariable statistical tool to pre-emptively identify students at future risk of suicidal behaviour (including plans and attempts) in the next 12-months. This new algorithm can identify the top 15% of at-risk individuals and capture 53.06 % of students who report a subsequent plan or attempt. COMPAS-S embeds this statistical tool into the wellbeing survey that all in-coming first year students are invited to take part in.

Our team then proactively reach out to students identified at elevated risk and, in collaboration with the student, conduct support and safety planning. We assess the student’s needs and link them in with appropriate resources and services, including Curtin Counselling, Student Services, Guild Clubs, and community groups. In some instance, this might mean talking with the student about attending the emergency department if they are currently in crisis.

Initial evaluation of COMPAS-S shows that identifying and providing personalised referrals for students identified as at-risk is associated with a 41.7% reduction in the probability of suicidal behaviour one year after the initial phone call. In recognition of the impact this has on university students, our team were awarded the 2022 Curtinnovation Award in the teaching and learning category.

description: We have measured the thermal conductivity tensor of a twinned YBa$_2$Cu$_3$O$_{7-x}$ single crystal as a function of angle $θ$ between the magnetic field applied parallel to the CuO$_2$ planes and the heat current direction, at different magnetic fields and at T=13.8 K. Clear fourfold and twofold variations in the field-angle dependence of $κ_{xx}$ and $κ_{xy}$ were respectively recorded in accordance with the d-wave pairing symmetry of the order parameter. The oscillation amplitude of the transverse thermal conductivity $κ^0_{xy}$ was found to be larger than the longitudinal one $κ^0_{xx}$ in the range of magnetic field studied here ($0 T $$ \le B \le 9 $$T$). From our data we obtain quantities that are free from non-electronic contributions and they allow us a comparison of the experimental results with current models for the quasiparticle transport in the mixed state.

description: Recent radio surveys have discovered a large number of low luminosity core dominated radio galaxies that are much more abundant than those at higher luminosities. These objects will be too faint in gamma-rays to be detected individually by Fermi. Nevertheless, they may contribute significantly to the unresolved extragalactic gamma-ray background. We consider here the possible contribution of these core dominated radio galaxies to the diffuse extragalactic gamma-ray background. Using published data available for all 45 of the radiogalaxies listed as detected counterparts in the Fermi FL8Y source list update to the 3FGL catalog, we have searched for radio maps which can resolve the core flux from the total source flux. Using high resolution radio maps we were able to obtain core fluxes for virtually every source. We then derived a relation between core radio flux and gamma-ray flux that we extrapolated to sources with low radio luminosities that are known to be highly core dominated. We then employed a very recent determination of the luminosity function for core dominated radio galaxies in order to obtain the contribution of all possible gamma-ray emitting radio galaxies to the unresolved extragalactic gamma-ray background. We find this contribution to be a possibly non-negligible, 4% - 18% of the background.

description: Experiments on planar Josephson junction architectures have recently been shown to provide an alternative way of creating topological superconductors hosting accessible Majorana modes. These zero-energy modes can be found at the ends of a one-dimensional channel in the junction of a two-dimensional electron gas (2DEG) proximitized by two spatially separated superconductors. The channel, which is below the break between the superconductors, is not in direct contact with the superconducting leads, so that proximity coupling is expected to be weaker and less well-controlled than in the simple nanowire configuration widely discussed in the literature. This provides a strong incentive for this paper which investigates the nature of proximitization in these Josephson architectures. At a microscopic level we demonstrate how and when it can lead to topological phases. We do so by going beyond simple tunneling models through solving self-consistently the Bogoliubov-de Gennes equations of a heterostructure multicomponent system involving two spatially separated $s$-wave superconductors in contact with a normal Rashba spin-orbit-coupled 2DEG. Importantly, within our self-consistent theory we present ways of maximizing the proximity-induced superconducting gap by studying the effect of the Rashba spin-orbit coupling, chemical potential mismatch between the superconductor and 2DEG, and sample geometry on the gap. Finally, we note (as in experiment) a Fulde-Ferrell-Larkin-Ovchinnikov phase is also found to appear in the 2DEG channel, albeit under circumstances which are not ideal for topological superconducting phase.

description: The canonical generator $G$ of local symmetries in Poincaré gauge theory is constructed as an integral over a spatial section $Σ$ of spacetime. Its regularity (differentiability) on the phase space is ensured by adding a suitable surface term, an integral over the boundary of $Σ$ at infinity, which represents the asymptotic canonical charge. For black hole solutions, $Σ$ has two boundaries, one at infinity and the other at horizon. It is shown that the canonical charge at horizon defines entropy, whereas the regularity of $G$ implies the first law of black hole thermodynamics.

description: $\mathcal{PT}$-symmetry --- invariance with respect to combined space reflection $\mathcal{P}$ and time reversal $\mathcal{T}$ --- provides a weaker condition than (Dirac) Hermiticity for ensuring a real energy spectrum of a general non-Hermitian Hamiltonian. $\mathcal{PT}$-symmetric Hamiltonians therefore form an intermediate class between Hermitian and non-Hermitian Hamiltonians. In this work, we derive the conditions for $\mathcal{PT}$-symmetry in the context of electronic structure theory, and specifically, within the Hartree-Fock (HF) approximation. We show that the HF orbitals are symmetric with respect to the $\mathcal{PT}$ operator \textit{if and only if} the effective Fock Hamiltonian is $\mathcal{PT}$-symmetric, and \textit{vice versa}. By extension, if an optimal self-consistent solution is invariant under $\mathcal{PT}$, then its eigenvalues and corresponding HF energy must be real. Moreover, we demonstrate how one can construct explicitly $\mathcal{PT}$-symmetric Slater determinants by forming $\mathcal{PT}$ doublets (i.e. pairing each occupied orbital with its $\mathcal{PT}$-transformed analogue), allowing $\mathcal{PT}$-symmetry to be conserved throughout the self-consistent process. Finally, considering the \ce{H2} molecule as an illustrative example, we observe $\mathcal{PT}$-symmetry in the HF energy landscape and find that the symmetry-broken unrestricted HF wave functions (i.e. diradical configurations) are $\mathcal{PT}$-symmetric, while the symmetry-broken restricted HF wave functions (i.e. ionic configurations) break $\mathcal{PT}$-symmetry.

description: Mixing of two fractions of a granular material in a slowly rotating two-dimensional drum is considered. The rotation is around the axis of the upright drum. The drum is filled partially, and mixing occurs only at a free surface of the material. We propose a simple theory of the mixing process which describes a real experiment surprisingly well. A geometrical approach without appealing to ideas of self-organized criticality is used. The dependence of the mixing time on the drum filling is calculated. The mixing time is infinite in the case of the half-filled drum. We describe singular behaviour of the mixing near this critical point.

description: Integrated circuits (ICs) are ubiquitous, ranging from consumer electronics to custom hardware. While scaling of CMOS feature sizes has enabled faster and smaller ICs, manufacturing smaller transistors and wires has become more challenging, particularly with the sub-wavelength lithography era. In response, foundries, to ensure the manufacturability of ICs at advanced CMOS nodes, have increased the number of design rules. The resultant difficulty in achieving design closure threatens the ability to create custom ICs within required timeframes. As a result, the use of advanced CMOS nodes has become unfavorable particularly for low-volume ICs wherein the design cost is higher than the fabrication cost. To this end, this dissertation explores opportunities to extend the use of advanced CMOS nodes for low-volume ICs by trading some amount of chip area for a reduction in design complexity, but without significantly affecting the performance and power consumption of ICs. To pursue this objective, we propose finding more optimal logic cell heights and wire pitches by selecting values more relaxed than the technology-allowed minimums.
To evaluate the impact of this optimization, we designed multiple digital ICs in a commercial 14/16 nm FinFET process. The silicon measurements indicate that relaxing the wiring pitches can reduce power consumption through coupling capacitance reduction. Moreover, taller logic cells that pose a minimal area increase penalty still perform comparably to shorter logic cells while eliminating routing problems. Lastly, using a layout pattern enumerator developed in-house, cell height increase is shown to mitigate manufacturing risks via layout simplification and re-use. These results suggest that logic cell height and wire pitch optimizations provide an excellent foundation for enabling low-volume customers to fabricate ICs in advanced CMOS nodes.

description: Language has been the subject of academic fascination for centuries, and the ability to communicate abstract notions through speech and writing allows humans to interact in ways that would not otherwise be possible. While the mechanisms of language processing have been studied extensively with behavioral and noninvasive neuroimaging methods, much about how the brain encodes language remains unknown. In this dissertation, I describe experiments using intracranial neurophysiology in humans to interrogate the mechanisms of language perception at high spatiotemporal resolution. First, I explore the neural mechanisms of visual word recognition in a large human intracranial dataset. By analyzing population sensitivity to a hierarchy of word features, I create a high-resolution map of stimulus encoding during single-word reading that reveals the early influence of lexical features in lingual and fusiform gyri followed by a cascade of lexical, orthographic, and semantic information in temporal and frontal lobes. Along with clustering analyses that show stimulus encoding in anatomically distributed populations, these results demonstrate that feed-forward, feed-back, and distributed processing mechanisms underlie visual word recognition. Second, I describe the development of an artificial language task designed to characterize the neural mechanisms of auditory word segmentation. The task is designed in three phases to probe how the brain tracks distributional regularity and the neural mechanisms of word segmentation with and without lexical access. Taken together, this work expands our understanding of the neural mechanisms of language processing using human intracranial neurophysiology.

description: The world is a complex and dynamic place. The incredibly dense and constantly changing information stream with which our senses are bombarded must be decomposed, taken in, and processed by any organism hoping to make enough sense of this world in order to survive to the next moment. For complex behaviors, and in particular a great many of those that we often feel define us as a human species, this dense sensory stream must not just be processed, but the important features of the environment must be further distilled and structured into representations that can then be stored long-term to guide future behavior through the joint processes of Learning and Memory. The primary goal of this thesis is to further our understanding of the neurobiological bases - at the subcellular, circuit, and network level - of learning and memory. The hippocampus, one of the most studied systems in the brain by far, is thought to play a central role in learning and memory. Principal cells in the hippocampus become tuned to environmental features, forming persistent representations of an animal’s environment, but the precise mechanisms by which these representations are formed, used, and maintained remain unresolved. By employing a variety of experimental techniques including in vivo two-photon calcium imaging, extracellular electrophysiology, optogenetics, and chemogenetics in awake, behaving mice, we attempted to characterize the subcellular and circuit determinants of place field representations and to connect them to these cells’ role in spatial learning and memory.

description: Alzheimer’s disease (AD) is a progressive neurodegenerative disease with limited therapeutic options, largely due to challenges in delivering drugs across the blood–brain barrier (BBB). In this study, we synthesized folic acid (FA) conjugated amphiphilic copolymers via reversible addition-fragmentation chain transfer (RAFT) polymerization to enhance the targeted delivery of donepezil (DZP) to the brain. The copolymers were self-assembled into micelles and extensively characterized for their size, zeta potential, and stability using dynamic light scattering (DLS) and transmission electron microscopy (TEM). The micelles were further evaluated for their ability to cross an in vitro BBB model and their cellular uptake by brain endothelial cells. FA conjugation was employed to exploit the folate receptor-mediated transport mechanism, which has shown potential for improving drug delivery across the BBB. This study demonstrates the feasibility of using FA functionalized micelles as a targeted delivery system, offering potential advancements in the treatment of Alzheimer’s disease.
