description: The advent of nanotechnology has hurtled the discovery and development of nanostructured materials with stellar chemical and physical functionalities in a bid to address issues in energy, environment, telecommunications and healthcare. In this quest, a class of two-dimensional layered materials consisting of alkali or coinage metal atoms sandwiched between slabs exclusively made of transition metal and chalcogen (or pnictogen) atoms arranged in a honeycomb fashion have emerged as materials exhibiting fascinatingly rich crystal chemistry, high-voltage electrochemistry, fast cation diffusion besides playing host to varied exotic electromagnetic and topological phenomena. Currently, with a niche application in energy storage as high-voltage materials, this class of honeycomb layered oxides serves as ideal pedagogical exemplars of the innumerable capabilities of nanomaterials drawing immense interest in multiple fields ranging from materials science, solid-state chemistry, electrochemistry and condensed matter physics. In this review, we delineate the relevant chemistry and physics of honeycomb layered oxides, and discuss their functionalities for tunable electrochemistry, superfast ionic conduction, electromagnetism and topology. Moreover, we elucidate the unexplored albeit vastly promising crystal chemistry space whilst outlining effective ways to identify regions within this compositional space, particularly where interesting electromagnetic and topological properties could be lurking within the aforementioned alkali and coinage-metal honeycomb layered oxide structures. We conclude by pointing towards possible future research directions, particularly the prospective realisation of Kitaev-Heisenberg-Dzyaloshinskii-Moriya interactions with single crystals and Floquet theory in closely-related honeycomb layered oxide materials.

"MEMOIRES INTIMES" BY GEORGES SIMENON: THE FOUR-SIDED VIEWPOINT OF A ONE-SIDED NARRATOR
Creators: name: Ruble, Michele Florence
Publisher: name: American University
Year: 2023

description: There is misrepresentation of both the subject and the nature of the text resulting from the author's inaccurate representation of the work to the reader. This study illustrates how this distortion is the result of the author's splitting his first-person narrative voice into four autonomous and antagonistic entities. The presentation and analysis of numerous contradictions and conflicts found in the separate accounts and viewpoints provided by each narrative entity substantiates the thesis that the author is misleading and manipulating the reader in an effort to validate false claims with regard to the objectivity of the text and its contents. Contrary to the author's claims, the text is not an impartial biographical tribute to the memory of his late daughter, Marie-Georges Simenon, but a prejudicial, self-justifying, autobiographical narrative detailing the long-standing feud between the author and his second wife, Denyse Simenon-Ouimet.
The Transitional Justice Framework agreed between the Colombian Government and the FARC—EP

Publisher: name: Routledge
Year: 2018

description: This chapter analyses the transitional justice framework defined by the peace agreements between the Fuerzas Armadas Revolucionarias de Colombia—Ejercito del Pueblo (FARC—EP) and the Colombian Government. Peace talks began officially in November 2012, with the parties reaching an agreement on 24 September 2016. The agreement on the victims of the conflict starts with the recognition by the government and the FARC—EP that the main aim of this agreement is to compensate victims. When the FARC—EP entered into a negotiation process with the Colombian Government, they did not entertain the possibility of embracing a transitional justice framework. The agreement recognizes the clarification of truth, coexistence, and non-repetition as one of the mechanisms that victims' organizations have demanded, thus its inclusion not only responds to best practices in the field but also to the citizen's demands. The agreement explicitly addresses forced disappearances, given that it is one of the main crimes of the Colombian armed conflict.

description: Topic Detection and Tracking (TDT) is a very active research question within the area of text mining, generally applied to news feeds and Twitter datasets, where topics and events are detected. The notion of "event" is broad, but typically it applies to occurrences that can be detected from a single post or a message. Little attention has been drawn to what we call "micro-events", which, due to their nature, cannot be detected from a single piece of textual information. The study investigates the feasibility of micro-event detection on textual data using a sample of messages from the Stack Overflow Q&A platform and Free/Libre Open Source Software (FLOSS) version releases from Libraries.io dataset. We build pipelines for detection of micro-events using three different estimators whose parameters are optimized using a grid search approach. We consider two feature spaces: LDA topic modeling with sentiment analysis, and hSBM topics with sentiment analysis. The feature spaces are optimized using the recursive feature elimination with cross validation (RFECV) strategy. In our experiments we investigate whether there is a characteristic change in the topics distribution or sentiment features before or after micro-events take place and we thoroughly evaluate the capacity of each variant of our analysis pipeline to detect micro-events. Additionally, we perform a detailed statistical analysis of the models, including influential cases, variance inflation factors, validation of the linearity assumption, pseudo R squared measures and no-information rate. Finally, in order to study limits of micro-event detection, we design a method for generating micro-event synthetic datasets with similar properties to the real-world data, and use them to identify the micro-event detectability threshold for each of the evaluated classifiers.

description: The ability to understand the real impact of research and clinical activities in the modern biomedical  academic environment is a Sisyphean task, given the increasing complexity of today's research and clinical care landscape. The sheer amount of relevant, related data from commercial and open data aggregators, as well as from the enterprise itself in systems such as the EHR, data warehouse, and research information systems, has never been
greater. The scholarly publishing process is obviously a very important step of disseminating scholarly discoveries to the broader community. This bibliographic metadata can also play a valuable role in helping an institution gain insights about its research and clinical activities that might not be discernable from other means, including some of the available institution-level data stores. These insights allow both investigators and the institutions themselves to convey the benefits and impact of their research and clinical efforts to stakeholders, thus providing valuable information that can be used for benchmarking, forecasting, and strategic planning activities.

description: Intensity mapping (IM) of spectral lines has the potential to revolutionize cosmology by increasing the total number of observed modes by several orders of magnitude compared to the cosmic microwave background (CMB) anisotropies. In this paper, we consider IM of neutral hydrogen (HI) in the redshift range $0 \lesssim z \lesssim 3$ employing a halo model approach where HI is assumed to follow the distribution of dark matter (DM) halos. If a portion of the DM is composed of ultralight axions then the abundance of halos is changed compared to cold dark matter below the axion Jeans mass. With fixed total HI density, $Ω_{\rm HI}$, assumed to reside entirely in halos, this effect introduces a scale-independent increase in the HI power spectrum on scales above the axion Jeans scale, which our model predicts consistent with N-body simulations. Lighter axions introduce a scale-dependent feature even on linear scales due to its suppression of the matter power spectrum near the Jeans scale. We use the Fisher matrix formalism to forecast the ability of future HI surveys to constrain the axion fraction of DM and marginalize over astrophysical and model uncertainties. We find that a HIRAX-like survey is a very reliable IM survey configuration, being affected minimally by uncertainties due to non-linear scales, while the SKA1MID configuration is the most constraining as it is sensitive to non-linear scales. Including non-linear scales and combining a SKA1MID-like IM survey with the Simons Observatory CMB, the benchmark "fuzzy DM" model with $m_a = 10^{-22}\text{ eV}$ can be constrained at the 10% level. For lighter ULAs this limit improves below 1%, and allows the possibility to test the connection between axion models and the grand unification scale across a wide range of masses.

description: The paper deals with the two-state (opening-closing of base pairs) model used to describe the fluctuation dynamics of a single bubble formation. We present an exact solution for the discrete and finite size version of the model that includes end effects and derive analytic expressions of the correlation function, survival probability and lifetimes for the bubble relaxation dynamics. It is shown that the continuous and semi-infinite limit of the model becomes a good approximation to exact result when a^N << 1, where N is bubble size and a, the ratio of opening to closing rates of base pairs, is the control parameter of DNA melting.

description: Semileptonic decays of doubly heavy baryons are studied in the framework of the relativistic quark model. The doubly heavy baryons are treated in the quark-diquark approximation. The transition amplitudes of heavy diquarks bb and bc going respectively to bc and cc are explicitly expressed through the overlap integrals of the diquark wave functions in the whole accessible kinematic range. The relativistic baryon wave functions of the quark-diquark bound system are used for the calculation of the transition matrix elements, the Isgur-Wise function and decay rates in the heavy quark limit.

description: We show that the dissipation rate bounds the rate at which physical processes can be performed in stochastic systems far from equilibrium. Namely, for rare processes we prove the fundamental tradeoff $\langle \dot S_\text{e} \rangle \mathcal{T} \geq k_{\text{B}} $ between the entropy flow $\langle \dot S_\text{e} \rangle$ into the reservoirs and the mean time $\mathcal{T}$ to complete a process. This dissipation-time uncertainty relation is a novel form of speed limit: the smaller the dissipation, the larger the time to perform a process.

title: Student perceptions of a sixth form college: a case study of Yale College, Wrexham.
Creators: name: Pritchard, Keith
Publisher: name: The Open University
Year: 1984

description: Research focusses upon an institution (Yale College, Wrexham) catering exclusively for Sixth Form students in the 16-19 age group. Content is based upon information collected from the selected student cohort, (240) over a two year attendance period. (1979-81). Its basic aims are: to identify student perception of the learning milieu; to monitor the consistency of attitudes over time and to examine the relative influences of internal (school based) or external (non-school based) factors. Only limited evidence was found of other sociological investigations exclusive to Sixth Form institutions and the nearest parallels were provided by research into Social processes within Secondary schools of the selective and non-selective variety. Research design seeks to establish whether identical processes, e.g. Differentiation and Polarisation, operate within a mixed. Comprehensive Sixth Form College, drawing its clientele primarily from seven contributory 11-16 schools. An attempt has been made to synthesise the Functionalist and Interactionist approaches to the study of Organisations. Objective measures of institutional attitudes were obtained from two separate essays written by each student at the 'entry' and 'departure' stage. These values indicated the spread of opinion within the pro/anti spectrum. Interviews with a selected sample,(32) post dated each essay and provided further subjective information, which added an illuminative dimension. Comprehensive student profiles, containing academic, socio-economic and other information, compiled from student record cards, formed the final raw data element. Finally, at the analytical stage, a mixture of interpretive and statistical techniques were employed to; describe the attitude and distribution pattern at each stage; assess the uniformity of results or pinpoint significant changes; clarify the role of contributory factors, and maintain the rigour and consistency of analysis.

description: In three dimensions, we consider the Einstein-Maxwell Lagrangian dressed by a nonminimally coupled scalar field in New Massive Gravity. For this theory, we provide two families of electrically charged Lifshitz black holes where their metric functions depend only on an integration constant. We calculate their masses using the quasilocal approach, as well as their entropy and electric charge. These charged configurations are interpreted as extremal in the sense that the mass vanishes identically while the entropy and electric charge are non zero thermodynamic quantities. Using these examples, we corroborate that the semiclassical entropy can be recovered through a charged Cardy-like formula, involving the corresponding magnetically charged solitons obtained by a double Wick rotation. Finally, the first law of thermodynamics, as well as the Smarr formula are also verified

description: We consider cosmological models with a scalar field with equation of state $w\ge 1$ that contract towards a big crunch singularity, as in recent cyclic and ekpyrotic scenarios. We show that chaotic mixmaster oscillations due to anisotropy and curvature are suppressed, and the contraction is described by a homogeneous and isotropic Friedmann equation if $w>1$. We generalize the results to theories where the scalar field couples to p-forms and show that there exists a finite value of $w$, depending on the p-forms, such that chaotic oscillations are suppressed. We show that $Z_2$ orbifold compactification also contributes to suppressing chaotic behavior. In particular, chaos is avoided in contracting heterotic M-theory models if $w>1$ at the crunch.

AN EXPERIMENTAL STUDY TO COMPARE THE EFFECTIVENESS OF A REGULAR CLASSROOM READING PROGRAM TO A REGULAR CLASSROOM READING PROGRAM WITH A COMPUTER-ASSISTED INSTRUCTION PROGRAM IN READING COMPREHENSION SKILLS IN GRADES TWO THROUGH FOUR

description: This study was designed to examine the relationship between the effectiveness of a regular classroom reading program to a regular classroom reading program with computer-assisted instruction program in reading comprehension skills in grades two through four. A pre-post test experimental design was used. The subjects consisted of 248 pupils in the experimental group in 1982 and 230 pupils in 1983, with 322 in the control group in 1982 and 320 in 1983. The experimental variable was a daily 10-minute computer drill program in reading comprehension that continued from September 1982 to May 1983. The dependent variable consisted of the subjects' scores on the California Achievement Test in the areas of literal comprehension, interpretive comprehension, and critical comprehension. The test results showed there was no significant difference between the second-, third-, and fourth-grade pupils who were taught by the classroom teacher and the computer-assisted program and second-, third-, and fourth-grade students who were taught by the regular reading program. The dependent measures were the scores on the California Achievement Test in the following three areas of reading comprehension: literal, interpretive, and critical. Since there were no significant differences between the experimental group and the control group and their pre-test scores on the three dependent variables--literal, interpretive, and critical comprehension, the assumption that these two groups were drawn from the same population was accepted. A post analysis of the experimental design revealed four factors which might have functioned as intervening or confounding variables in this study: (1) Experimental teacher resistance; (2) Selection of the California Achievement Test as the measuring instrument; (3) The time variable appears to be noneffective to have the same block of time for all grades; (4) The computer-assisted instruction program did not contain interesting material geared to the average classroom instructional program. The recommendations from this study are: (1) Teachers must be trained to be computer literate; (2) Time spent using the computer must be carefully evaluated; (3) The Metropolitan Achievement Test might prove to be a more sensitive instrument for measuring the effectiveness of the computer-assisted program; (4) The computer-assisted program material should be more colorful, interesting, and geared to incorporate the material learned in the classroom.

Year: 2016

description: The University of British Columbia is committed to sustainability projects and implementing infrastructure that can improve sorting behaviour (Sustainability Plans, n.d.). The research question for this study is: does adding a lid to a garbage bin that is part of a larger sorting station - in which lids are already present - increase sorting behaviour? Through a covert naturalistic observation, 181 participants were observed and coded as they used the sorting stations present in the Irving K. Barber library. The results indicate that there is a positive correlation of 0.21, suggesting that lid presence on garbage bins is correlated to increases in effective sorting behaviour. Based on this study, UBC is recommended to add lids to the garbage bins at sorting stations in which other lids are present to increase sorting behaviour.

Numerical Discretization of Variational Phase Field Model for Phase Transitions in Ferroelectric Thin Films

description: Phase field methods have been widely used to study phase transitions and polarization switching in ferroelectric thin films. In this paper, we develop an efficient numerical scheme for the variational phase field model based on variational forms of the electrostatic energy and the relaxation dynamics of the polarization vector. The spatial discretization combines the Fourier spectral method with the finite difference method to handle three-dimensional mixed boundary conditions. It allows for an efficient semi-implicit discretization for the time integration of the relaxation dynamics. This method avoids explicitly solving the electrostatic equilibrium equation (a Poisson equation) and eliminates the use of associated Lagrange multipliers. We present several numerical examples including phase transitions and polarization switching processes to demonstrate the effectiveness of the proposed method.
A Lambda Calculus for Quantum Computation

description: The classical lambda calculus may be regarded both as a programming language and as a formal algebraic system for reasoning about computation. It provides a computational model equivalent to the Turing machine, and continues to be of enormous benefit in the classical theory of computation. We propose that quantum computation, like its classical counterpart, may benefit from a version of the lambda calculus suitable for expressing and reasoning about quantum algorithms. In this paper we develop a quantum lambda calculus as an alternative model of quantum computation, which combines some of the benefits of both the quantum Turing machine and the quantum circuit models. The calculus turns out to be closely related to the linear lambda calculi used in the study of Linear Logic. We set up a computational model and an equational proof system for this calculus, and we argue that it is equivalent to the quantum Turing machine.

INCOMPLETE CHARACTERS: PIRANDELLO'S FATHER, CHEKHOV'S COLONEL, AND BRECHT'S GOOD WOMAN (ITALY, RUSSIA, GERMANY)
Creators: name: London, Todd
Publisher: name: American University
Year: 2023

description: This study aims at a reading of character that allows for psychological inconsistency and behavioral discontinuity. The readings of Luigi Pirandello's Six Characters in Search of an Author, Anton Chekhov's Three Sisters, and Bertolt Brecht's The Good Woman of Setzuan attempt to account for and allow for apparent disunities in character opinion and behavior within a coherent interpretation. They try to suggest ways for the actors playing the roles to accommodate such disunities, while also creating coherent interpretations in their performances. Throughout, I have tried to unite the concerns of critics and those of actors, the least explored relationship in the collaborative process of theater. Pirandello's character The Father, Chekhov's Colonel Vershinin, and Brecht's Shen Te/Shui Ta are each incomplete in some way. They lack the means for survival or happiness. They live at odds with their circumstances. In order to gain control over these circumstances, they make attempts to revise themselves and the world around them. But these efforts to alter reality contradict that reality and keep the characters out of sync with it. Because they can never remake the world, their thwarted attempts to do so remain incomplete. Their behavior seems discontinuous; their psychology, fragmentary and unfinished. These characters are incomplete in another way. They are theatrical creations and, as such, can only fully exist in performance when interpreted by the actor. Moreover, they are conscious creations in that their status as characters for the stage is acknowledged and explored by their creators. They cannot be whole human beings precisely because they are characters. The readings--not the theory of character--are the center of this study. Each play redefines the problem of character completeness. The Father attempts to rewrite his abandoned life. Vershinin leaps out of the actual present into an imagined future. Shen Te creates Shui Ta in order to complete herself. Each author encounters the futility of attempts to complete oneself by changing the world.

description: We investigate one-electron properties of one-dimensional self-similar structures called limit quasi-periodic lattices. The trace map of such a lattice is nonconservative in contrast to the quasi-periodic case, and we can determine the structure of its attractor. It allows us to obtain the three new features of the present system: 1) The multi-fractal characters of the energy spectra are {\it universal}. 2) The supports of the $f(α)$-spectra extend over the whole unit interval, $[0, 1]$. 3) There exist marginal critical states.

description: We develop a theory describing the transition to a spatially homogeneous regime in a mixing flow with a chaotic in time reaction. The transverse Lyapunov exponent governing the stability of the homogeneous state can be represented as a combination of Lyapunov exponents for spatial mixing and temporal chaos. This representation, being exact for time-independent flows and equal Péclet numbers of different components, is demonstrated to work accurately for time-dependent flows and different Péclet numbers.

description: The idea of reduction of couplings consists in searching for renormalization group invariant relations between parameters of a renormalizable theory that hold to all orders of perturbation theory. Based on the principle of the reduction of couplings, one can construct Finite Unified Theories (FUTs) which are $N=1$ supersymmetric Grand Unified Theories that can be made all-order finite. The prediction of the top quark mass well in advance of its experimental discovery and the prediction of the light Higgs boson mass in the range $\sim 121-126$ GeV much earlier than its experimental discovery are among the celebrated successes of such models. Here, after a brief review of the reduction of couplings method and the properties of the resulting finiteness in supersymmetric theories, we analyse four phenomenologically favoured models: a minimal version of the $N=1$ $SU(5)$, a finite $N=1$ $SU(5)$, a $N=1$ finite $SU(3)\otimes SU(3)\otimes SU(3)$ model and a reduced version of the Minimal Supersymmetric Standard Model (MSSM). A relevant update in the phenomenological evaluation has been the improved light Higgs-boson mass prediction as provided by the latest version of $\texttt{FeynHiggs}$. All four models predict relatively heavy supersymmetric spectra that start just below or above the TeV scale, consistent with the non-observation LHC results. Depending on the model, the lighter regions of the spectra could be accessible at CLIC, while the FCC-hh will be able to test large parts of predicted spectrum of each model. The lightest supersymmetric particle (LSP), which is a neutralino, is considered as a cold dark matter candidate and put to test using the latest $\texttt{MicrOMEGAs}$ code.

title: Stress corrosion cracking, and corrosion fatigue in aluminium alloy 7017 with and without residual stresses
Creators: name: Hermann, Reinhold
Publisher: name: The Open University
Year: 1986

description: This thesis presents recent work on the stress corrosion cracking of aluminium alloy 7017 with and without residual stresses, and some results on corrosion fatigue. Chapter I contains a literature review of the stress-corrosion cracking (SCC) and corrosion fatigue (CF) cracking mechanisms. It explains techniques, practices and the conclusions reached when Al-Zn-Mg-(Cu) are employed in such tests. The latter part of the review is devoted to recent work in aluminium alloys containing residual stresses when subjected to cyclic loading. In Chapter II a description is given of the properties of the alloy, followed by specimen design, environmental aspects of testing, tensile loading of specimens and the deliberate introduction of residual stresses to test pieces for both stress corrosion and corrosion fatigue studies. Chapter III outlines the experimental results of SCC without residual stress. Here the kinetics of sub-critical crack growth are assessed by analysing the v-K curves of the alloy when stress-corroded in various moist air environments. The effects of pre-exposure to salt solution prior to loading is described in the light of these experiments. Also in Chapter III corrosion behaviour is discussed where specimens are deliberately pre-loaded in compression prior to SCC testing. It is shown that crack growth can be achieved without bolt-loading. The effects of environment and morphology of fractures are described and compared with those of Chapter III. Chapter IV examines the corrosion fatigue behaviour of the alloy under the influence of residual stresses and cyclic loading, with reference to crack -growth rates under compressive loading, frequency and pre-exposure effects. A model for assessing the residual stress ahead of the crack tip is suggested, using data from crack closure measurements.
INCOMPLETE CHARACTERS: PIRANDELLO'S FATHER, CHEKHOV'S COLONEL, AND BRECHT'S GOOD WOMAN (ITALY, RUSSIA, GERMANY)

description: This study aims at a reading of character that allows for psychological inconsistency and behavioral discontinuity. The readings of Luigi Pirandello's Six Characters in Search of an Author, Anton Chekhov's Three Sisters, and Bertolt Brecht's The Good Woman of Setzuan attempt to account for and allow for apparent disunities in character opinion and behavior within a coherent interpretation. They try to suggest ways for the actors playing the roles to accommodate such disunities, while also creating coherent interpretations in their performances. Throughout, I have tried to unite the concerns of critics and those of actors, the least explored relationship in the collaborative process of theater. Pirandello's character The Father, Chekhov's Colonel Vershinin, and Brecht's Shen Te/Shui Ta are each incomplete in some way. They lack the means for survival or happiness. They live at odds with their circumstances. In order to gain control over these circumstances, they make attempts to revise themselves and the world around them. But these efforts to alter reality contradict that reality and keep the characters out of sync with it. Because they can never remake the world, their thwarted attempts to do so remain incomplete. Their behavior seems discontinuous; their psychology, fragmentary and unfinished. These characters are incomplete in another way. They are theatrical creations and, as such, can only fully exist in performance when interpreted by the actor. Moreover, they are conscious creations in that their status as characters for the stage is acknowledged and explored by their creators. They cannot be whole human beings precisely because they are characters. The readings--not the theory of character--are the center of this study. Each play redefines the problem of character completeness. The Father attempts to rewrite his abandoned life. Vershinin leaps out of the actual present into an imagined future. Shen Te creates Shui Ta in order to complete herself. Each author encounters the futility of attempts to complete oneself by changing the world.

description: Supersymmetric or Darboux transformations are used to construct local phase equivalent deep and shallow potentials for $\ell \neq 0$ partial waves. We associate the value of the orbital angular momentum with the asymptotic form of the potential at infinity which allows us to introduce adequate long-distance transformations. The approach is shown to be effective in getting the correct phase shift effective range expansion. Applications are considered for the $^1P_1$ and $^1D_2$ partial waves of the neutron-proton scattering.

SINGULAR VALUE DECOMPOSITION USING A JACOBI ALGORITHM WITH AN UNBOUNDED ANGLE OF ROTATION (CYCLIC, SVD, REAL SYMMETRIC)
Creators: name: Booker, T. Hoy
Publisher: name: American University
Year: 2023

description: This dissertation presents an investigation of the convergence of the cyclic Jacobi algorithm for use in the computation of the Singular Value Decomposition (SVD) of an arbitrary m x n matrix. For reference, it can be shown that this problem is equivalent to that of finding the eigenvalues and eigenvectors of a real symmetric matrix. This dissertation is presented in terms of SVD instead of the more traditional eigen-solution of a real symmetric matrix. The reason for this is that in recent years SVD has become increasingly popular in many fields of the applied sciences. This presentation considers the convergence of cyclic Jacobi methods using an unbounded angle of rotation. It provides a partial proof for the general case, two proofs for an m x 3 matrix, an analysis of the internal character of the "threshold" cyclic Jacobi method and a general proof of convergence of the threshold method.
