description: Vanadium dioxide ($VO_{2}$) exhibits strong infrared optical switching due to its insulator-metal phase-transition property. However, in the visible wavelengths, it's intrinsic optical switching is quite low. Current research explores solutions like multilayering, intricate structural patterning, high thermal budget processes and costly metals for improved color switching. Nonetheless, the color gamut coverage with these methodologies remains notably limited. This work overcomes these limitations and demonstrates dynamic multi-colour switching covering a large color gamut using a simple, unpatterned, ultrathin ($\sim$ $\fracλ{14}$, where wavelength $λ$ is taken as 575 nm at the center of visible spectrum) asymmetric Fabry-Pérot structure of $VO_{2}$ on Aluminium (Al). We use the transfer matrix method to design the $VO_{2}/Aluminium\,(Al)/Sapphire$ structure for maximum visible reflectance switching. $VO_{2}$ films are synthesized using a simple, low thermal budget atmospheric oxidation of Vanadium (V). With varying oxidation durations, different colors of the oxidized samples are observed. Consistent and reversible color-switching is observed visibly and in reflectance measurements with the change in temperature from low (RT $\sim$ 30$^{\circ}$C) to high (HT $\sim$ 100$^{\circ}$C) or vice versa due to the phase transition property of the $VO_{2}$ layer in the structure. Compared to the existing studies, this work shows a significant change in chromaticities and covers a large color gamut when plotted on the CIE chromaticity diagram. This work has potential applications in the fields of display, thermochromic structures, and visible camouflage.

description: Vibrational properties of inclusion complexes with cyclodextrins are studied by means of Raman spectroscopy and numerical simulation. In particular, Raman spectra of the non-steroidal, anti-inflammatory drug indomethacin undergo notable changes in the energy range between 1600 and 1700 cm$^{-1}$ when inclusion complexes with cyclodextrins are formed. By using both \emph{ab initio} quantum chemical calculations and molecular dynamics, we studied how to relate such changes to the geometry of the inclusion process, disentangling single-molecule effects, from changes in the solid state structure or dimerization processes.

description: KY 80 (Hazard to Watergap) was constructed using abundantly available crushed sandstone. The pavements were designed to have adequate load-carrying capibilities and stability but were considered to be experimental (see Figure 1). It was intended that performance would be monitored and that undesirable features and performance would be identified and studied. Such surveillance was discontinued before construction was completed.  Recently, the need has arisen for testing and evaluation of some of the experimental sections. Some spalls, scuffs, and artesian water have been observed. Excessive water has appeared in the shoulder, median, and mainline. There has been at least one spot failure.  The Kentucky Transportation Research Program was asked to submit a work plan to evaluate the performance of some experimental features. A plan was approved, and the investigations began on October 1, 1982. At this time, the investigative work includes the section of KY 80 from Milepost 9 to Milepost l8. Some data were already available for sections near the Floyd-Knott County line. Those data were obtained in l981 while conducting a study of in-place strength characteristics of sandstone rock subgrades. The investigation reported herein involved the following: condition survey and photologging; Road Rater testing and survey; coring, drilling, and sampling of pavement materials; and testing of cores and samples recovered from the pavement.

description: We consider locally linear Z_p x Z_p actions on the four-sphere. We present simple constructions of interesting examples, and then prove that a given action is concordant to its linear model if and only if a single surgery obstruction taking to form of an Arf invariant vanishes. We discuss the behavior of this invariant under various connected-sum operations, and conclude with a brief discussion of the existence of actions which are not concordant to their linear models.

description: We introduce a novel hybrid algorithm to simulate the real-time evolution of quantum systems using parameterized quantum circuits. The method, named "projected - Variational Quantum Dynamics" (p-VQD) realizes an iterative, global projection of the exact time evolution onto the parameterized manifold. In the small time-step limit, this is equivalent to the McLachlan's variational principle. Our approach is efficient in the sense that it exhibits an optimal linear scaling with the total number of variational parameters. Furthermore, it is global in the sense that it uses the variational principle to optimize all parameters at once. The global nature of our approach then significantly extends the scope of existing efficient variational methods, that instead typically rely on the iterative optimization of a restricted subset of variational parameters. Through numerical experiments, we also show that our approach is particularly advantageous over existing global optimization algorithms based on the time-dependent variational principle that, due to a demanding quadratic scaling with parameter numbers, are unsuitable for large parameterized quantum circuits.

description: A unique acoustic emission monitoring system originally developed for inprocess weld monitoring has been used to monitor fatigue crack growth in a highway bridge during normal traffic loading. The system was able to clearly and reliably detect the presence of fatigue cracks that were adjacent to a row of bolts. The results of the brief experiment show that the signal processing used in this AE system may allow drastic improvements in the ability of acoustic emission to reliably detect propagating bridge flaws under adverse conditions.
Poetic consciousness and the novel Wildgoose
Creators: name: Evans, Sally
Publisher: name: Lancaster University
Year: 2021

description: Wildgoose is a novel about poets, placing protagonists against the historical background of the poetry world in Northern England and Scotland from 1965 to 2015, investigating how poet cousins, female and male, would fare setting out as poets. I added a group of characters to the poetry scene, drawing on the bildungsroman genre to chart my poets’ development. My novel has ‘episodes’ in set years, averaging five-year intervals. Eric becomes accepted as a poet in Scotland. Living with her son among friends and her few sexual partners, Maeve writes a long poem – Wildgoose – which disappears on its completion. Though upset, she carries on and moves to Scotland when her son becomes independent. Later her son rediscovers her poem and invites her back to Scotland. She reads the opening at the concert where she is pushed off the cinema stage and fatally injured. In a substantial Coda, her son’s associate Mary follows Eric while seeking Maeve’s poem. Eric is upset and becomes suicidal, then dies on a journey of repentance. Mary finds and reads Wildgoose in Durham University, and arranges for its publication. The novel ends with Eric’s reflections on his life in poetry. Wildgoose is followed by a four-part reflective essay, discussing the implications of historical time and place, structural and narrative choices, devices for showing poetic consciousness, and the inclusion of poems in the novel. I identify consciousness as the key feature in poets’ experience of life, while showing the experience of poets in a defined part of the poetry world. I use geese as symbols of inspiration and consciousness as they travel the country above the poets in the novel. It is unusual to look at poets in the North of England and Scotland in the light of their personal professional experience rather than judging them purely on worldly success.
I can hear you writing : reflections on voice and writing
Creators: name: Quinn, Andrew Harry
Publisher: name: University of British Columbia
Year: 2009

description: Written in the form of a narrative, this thesis explores the phenomenon of voice in writing, and what the development of an awareness of the multiplicity voices while writing and reading can mean for language learners. This thesis is also a personal reflection of depression, and a recollection of individual, family and life events. One chapter takes the form of a unified narrative, while another presents anecdotal recollections. It is, in this sense, an exploration of voices through an analysis of available academic and public writing, and a personal inquiry into how the concept of voices in writing has affected my development as an individual and as a writer. The first section reviews some of the academic and public literature on writing and voice, and reveals that early writing on the issue of voice reflected a monolistic theory of voice. That is, that there is one voice that as writers we must find within ourselves, or there is a voice of the author that we must seek out. However, views of the multiplicity of voices in writing are increasingly common. While philosophical tradition since Plato has mistrusted writing and viewed it as secondary to speech, philosophy has nevertheless employed writing to further its own inquiries. Re/viewing the issue of voice in writing may be one way to deal with this long-standing schism between speech and writing. There is a need to further problematize the field of writing, not searching for ways to simplify the process but seeking ways to celebrate the inherent complexity, ambiguity, and paradoxical nature of writing. The thesis concludes with a reflection on the need to seriously consider the significance of voices in writing in first and second language instruction.
Experiments in quantum optics : scalable entangled states and quantum computation with cluster states

Subjects: subject: Quantum optics Experiments
subject: Quantum entanglement

description: Quantum optics is an extremely fruitful area of research in that it allows the probing of fundamental and basic science, as well as the opportunity to investigate potential applications that exploit these exotic phenomena. Entanglement is a uniquely quantum phenomenon that is a key feature of quantum mechanics. In this thesis we investigate the scalability of entangled states of light, as well as modest demonstrations of one-way quantum computations, based on a resource that exploits entanglement. Scalability has been a bottleneck of entanglement experiments since the first demonstrations began surfacing a few decades ago. In Part II of this thesis we investigate different methods of multiplexing quantum light modes in order to achieve a scalable architecture. 2 experiments are presented in spatial multiplexing, that lead to programmable linear optics networks that can produce up to 8 entangled modes. Building on this, and shifting domains we then demonstrate temporal multiplexing, where we entangle tens of thousands of quantum modes together in a highly entangled state called a cluster state. This is several orders of magnitude larger than any entangled state created to date, in any platform (be it atomic or electronic). The highly entangled cluster state is a universal resource for quantum computing, and we investigate a particular class of computations in Part III. We demonstrate that a cluster state consisting of only 4 highly entangled quantum modes is sufficient for universal 1-mode Gaussian quantum computing. Further, we demonstrate a tuneable entanglement gate that can be retrofitted to cluster states of arbitrary size or shape. Although the experiments in Part II and Part III are conceptually quite different, they employ very similar optical and electronic equipment. These experimental techniques as well as a survey of relevant quantum optics theory is presented in Part I.

Demographic transition and transformation of regulation and law in Japan

Publisher: name: The Australian National University
Year: 2010
Subjects: subject: KT4648.R93 2010 ANU
subject: Law Social aspects Japan
subject: Demographic transition Japan

description: This dissertation argues that Japan's rapid and dramatic demographic transition is having a transformative effect on regulation and law. It argues that the myriad social and economic challenges associated with demographic transition are a catalyst for collaborative forms of governance - that is, governance that employs indirect and pluralist regulation to supervise and co-opt an otherwise autonomous non-state sector. It contends that Japan's tradition of legal pluralism, which blends formal and contextual elements, is conducive to this collaborative approach to grappling with radical demographic change. However, this tradition has also created an accountability deficit prompting an apparent 'liberal ascendancy' and strengthened commitment to the Rule of Law. In three case studies-retirement pensions, childcare, and adult guardianship - this dissertation demonstrates that the exigencies of demographic change have catalysed compromise between the liberal tradition and the proliferation of indirect, collaborative, and 'responsive' forms of regulation. As evidence, this dissertation charts the growth of 'regulatory' and 'accountability' networks, which span the public and private sectors, and the parallel development of 'hybridisation' of public and private law in Japan.
Dynamics of entanglement after exceptional quantum quench

description: We investigate a quantum quench from a critical to an exceptional point. The initial state, prepared in the ground state of a critical hermitian system, is time evolved with a non-hermitian SSH model, tuned to its exceptional point. The single particle density matrix exhibits supersonic modes and multiple light cones, characteristic to non-hermitian time evolution. These propagate with integer multiples of the original Fermi velocity. In the long time limit, the fermionic Green's function decays spatially as $1/x^2$, in sharp contrast to the usual $1/x$ decay of non-interacting fermions. The entanglement entropy is understood as if all these supersonic modes arise from independent quasiparticles (though they do not), traveling with the corresponding supersonic light cone velocity. The entropy production rate decreases with time and develops plateaus during the time evolution, signaling the distinct velocities in the propagation of non-local quantum correlations. At late times, the entanglement entropy saturates to a finite value, satisfying a volume law.

description: An annual highway safety program is proposed each year for the State of Kentucky in order to comply with Section 402, Title 23 of the United States Code. This program includes the identification, programming, budgeting, and evaluation of safety projects. This report is the fifth in a series of annual reports which have been included as the problem identification portion of Kentucky's Annual Highway Safety Plan.  In the past, the approach to problem identification has been to identify problem areas in the 18 highway safety program areas (standards). While the search for problems in each of these standard areas will continue, certain program areas were identified for emphasis. The result was an analysis of 12 problem areas, with emphasis on alcohol and occupant protection. Recommendations were made for programs which could serve as countermeasures for the highway safety problems identified and for studies to develop and evaluate such programs.

description: Um der Diversität in Klassenräumen des 21. Jahrhunderts besser gerecht zu werden, sollte Unterricht von der Planung an für ein möglichst breites Spektrum an Lernenden zugänglich gestaltet werden. Ein Konzept mit evidenzbasierten Strategien zum Abbau von unnötigen Lernbarrieren und zur Erreichung individuell anspruchsvoller curricularer Lernziele ist das Universal Design for Learning (UDL). Die Implementation des UDL-Rahmenkonzepts in den Fachunterricht stellt jedoch für (angehende) Lehrkräfte eine Herausforderung dar. Das auf Basis einer umfangreichen Literaturrecherche entwickelte Planungsmodell ChemDive soll vor dem Hintergrund ausgewählter didaktischer Funktionen die systematische Integration von UDL-Prinzipien in Unterrichtsstunden erleichtern. In zukünftigen Studien kann dieses für das Fach Chemie entwickelte Modell empirisch geprüft und für andere Fächer adaptiert werden.
description: Lessons should be accessible to the widest possible range of students to meet the challenge of highly diverse classrooms in the 21st century. One concept for reducing unnecessary bar-riers and reaching high educational expectations is called Universal Design for Learning (UDL). However, applying the UDL framework throughout the lesson planning process in different subjects is a big challenge for many (prospective) teachers. This article presents the literature-based planning model ChemDive with selected didactic functions to infuse UDL into chemistry classroom practice. Future studies should focus on further empirical proof and effects of the model and adaptations for other subjects.

description: We study the evolution and oscillations of fixed massive neutrinos interacting with stochastic gravitational waves (GWs). The energy spectrum of these GWs is Gaussian, with the correlator of the amplitudes being arbitrary. We derive the equation for the density matrix for flavor neutrinos in this case. In the two flavors approximation, this equation can be solved analytically. We find the numerical solution for the density matrix in the general case of three neutrino flavors. We consider merging binary black holes as sources of stochastic GWs with realistic spectra. Both normal and inverted mass orderings are analyzed. We discuss the relaxation of the neutrino fluxes in stochastic GWs emitted mainly by supermassive black holes. In this situation, we obtain the range of energies and the propagation lengths for which the relaxation process is the most efficient. We discuss the application of our results for the observation of fluxes of astrophysical neutrinos.

description: It is well-known that a charged particle moving with constant velocity in vacuum does not radiate. In a medium the situation can be different. If the so called Cherenkov condition is satisfied, i.e. the particle velocity exceeds the phase speed in the medium, the particle will radiate. We show that a charge moving with a constant velocity in a gas of photons emits Cherenkov radiation, even in the gamma-ray regime, due to nonlinear quantum electrodynamic effects. Our result is evaluated with respect to the radiation background in the early universe, and it is argued that the effect can be significant.

description: In $α$-RuCl$_3$, an external magnetic field applied within the honeycomb plane can induce a transition from a magnetically ordered state to a disordered state that is potentially related to the Kitaev quantum spin liquid. In zero field, single crystals with minimal stacking faults display a low-temperature state with in-plane zigzag antiferromagnetic order and a three-layer periodicity in the direction perpendicular to the honeycomb planes. Here, we present angle-dependent magnetization, ac susceptibility, and thermal transport data that demonstrate the presence of an additional intermediate-field ordered state at fields below the transition to the disordered phase. Neutron diffraction results show that the magnetic structure in this phase is characterized by a six-layer periodicity in the direction perpendicular to the honeycomb planes. Theoretically, the intermediate ordered phase can be accounted for by including spin-anisotropic couplings between the layers in a three-dimensional spin model. Together, this demonstrates the importance of interlayer exchange interactions in $α$-RuCl$_3$.
description: This article supersedes arXiv:1807.06192 which proposed that the intermediate-field ordered phase displays an in-plane magnetic order different from zigzag

description: A multi-species magnetized collisional nonthermal plasma system containing inertial ion species, non-inertial electron species following nonthermal $κ-$ distribution, and immobile dust particles, is considered to examine the characteristics of the dissipative dust-ion-acoustic (DIA) soliton modes, \textbf{theoretically and parametrically}. The electrostatic solitary modes are found to be associated with the low frequency dissipative dust-ion-acoustic solitary waves (DIASWs). The ion-neutral collision is taken into account, and the influence of ion-neutral collisional effects on the dynamics of dissipative DIASWs is investigated. It is reported that most of the plasma mediums in space and laboratory are far from thermal equilibrium, and the particles in such plasma systems are well fitted via the $κ-$nonthermal distribution than via the thermal Maxwellian distribution. The reductive perturbation approach is adopted to derive the damped KdV (dKdV) equation, and the solitary wave solution of the dKdV equation is derived via the tangent hyperbolic method to analyze the basic features (amplitude, width, speed, time evolution, etc.) of dissipative DIASWs. The propagation nature and also the basic features of dissipative DIASWs are seen to influence significantly due to the variation of the plasma configuration parameters and also due to the variation of the supethermality index $κ$ in the considered plasma system. The implication of the results of this study could be useful for better understanding the electrostatic localized disturbances, in the ion length and time scale, in space and experimental dusty plasmas, where the presence of excess energetic electrons and ion-neutral collisional damping are accountable.

description: We use noncommutative topology to study T-duality for principal torus bundles with H-flux. We characterize precisely when there is a "classical" T-dual, i.e., a dual bundle with dual H-flux, and when the T-dual must be "non-classical," that is, a continuous field of noncommutative tori. The duality comes with an isomorphism of twisted $K$-theories, required for matching of D-brane charges, just as in the classical case. The isomorphism of twisted cohomology which one gets in the classical case is replaced in the non-classical case by an isomorphism of twisted cyclic homology. An important part of the paper contains a detailed analysis of the classifying space for topological T-duality, as well as the T-duality group and its action. The issue of possible non-uniqueness of T-duals can be studied via the action of the T-duality group.

description: We present full photometric coverage and spectroscopic data for soft GRB 201015A with a redshift z = 0.426. Our data spans a time range of 85 days following the detection of GRB. These observations revealed an underlying supernova SN 201015A with a maximum at $8.54 \pm $1.48 days (rest frame) and an optical peak absolute magnitude $-19.45_{-0.47}^{+0.85}$ mag. The supernova stands out clearly, since the contribution of the afterglow at this time is not dominant, which made it possible to determine SN's parameters. A comparison of these parameters reveals that the SN 201015A is the earliest (the minimum $T_{max}$) known supernova associated with gamma-ray bursts. Spectroscopic observations during the supernova decay stage showed broad lines, indicating a large photospheric velocity, and identified this supernova as a type Ic-BL. Thus, the SN 201015A associated with the GRB 201015A becomes the 27th SN/GRB confirmed by both photometric and spectroscopic observations. Using the results of spectral analysis based on the available data of Fermi-GBM experiment, the parameters $E_\text{p,i} = 20.0 \pm 8.5$ keV and $E_\text{iso} = (1.1 \pm 0.2) \times 10^{50}$ erg were obtained. According to the position of the burst on the $E_\text{p,i}$-$E_\text{iso}$ correlation, GRB 201015A was classified as a Type II (long) gamma-ray burst, which was also confirmed by the $T_\text{90,i}$-$EH$ diagram.

description: Active Brownian engines rectify energy from reservoirs composed of self-propelling non-equilibrium molecules into work. We consider a class of such engines based on an underdamped Brownian particle trapped in a power-law potential. The energy they transform has thermodynamic properties of heat only if the non-equilibrium reservoir can be assigned a suitable effective temperature consistent with the second law and thus yielding an upper bound on the engine efficiency. The effective temperature exists if the total force exerted on the particle by the bath is not correlated with the particle position. In general, this occurs if the noise autocorrelation function and the friction kernel are proportional as in the fluctuation-dissipation theorem. But even if the proportionality is broken, the effective temperature can be defined in restricted, fine-tuned, parameter regimes, as we demonstrate on a specific example with harmonic potential.

description: This paper analyses the evolution of renewable energy cooperatives, examining all such cooperatives founded in German districts between 2006 and 2016. The rise of the cooperative form in renewable energy production is a prominent example of the strong involvement of users in market formation. We investigate the effects of ‘institutional relatedness’, arguing that renewable energy cooperatives can leverage the organizational knowledge and the legitimacy gained by cooperatives active in other industries in the same district. Using an organizational ecology approach, we find that the local presence of cooperatives in other industries indeed supported the founding of renewable energy cooperatives.

description: Mindfulness-based therapies have been shown to be effective in improving mental health, and technology-based methods have the potential to expand the accessibility of these therapies. To enable real-time personalized content generation for mindfulness practice in these methods, high-quality computer-synthesized text-to-speech (TTS) voices are needed to provide verbal guidance and respond to user performance and preferences. However, the user-perceived quality of state-of-the-art TTS voices has not yet been evaluated for administering mindfulness meditation, which requires emotional expressiveness. In addition, work has not yet been done to study the effect of physical embodiment and personalization on the user-perceived quality of TTS voices for mindfulness. To that end, we designed a two-phase human subject study. In Phase 1, an online Mechanical Turk between-subject study (N=471) evaluated 3 (feminine, masculine, child-like) state-of-the-art TTS voices with 2 (feminine, masculine) human therapists' voices in 3 different physical embodiment settings (no agent, conversational agent, socially assistive robot) with remote participants. Building on findings from Phase 1, in Phase 2, an in-person within-subject study (N=94), we used a novel framework we developed for personalizing TTS voices based on user preferences, and evaluated user-perceived quality compared to best-rated non-personalized voices from Phase 1. We found that the best-rated human voice was perceived better than all TTS voices; the emotional expressiveness and naturalness of TTS voices were poorly rated, while users were satisfied with the clarity of TTS voices. Surprisingly, by allowing users to fine-tune TTS voice features, the user-personalized TTS voices could perform almost as well as human voices, suggesting user personalization could be a simple and very effective tool to improve user-perceived quality of TTS voice.

The Axion Quality Problem: Global Symmetry Breaking and Wormholes

description: Continuous global symmetries are expected to be broken by gravity, which can lead to important phenomenological consequences. A prime example is the threat that this poses to the viability of the Peccei-Quinn solution to the strong CP problem. In this paper, we explore the impact of wormholes as a source of global symmetry breaking by gravity. We review the current status of wormholes and global symmetries and note that, surprisingly, the axion has a quality problem within non-perturbative Einstein gravity. Although these wormholes lead to a large breaking of global symmetries, we show that their effect is nonetheless relevant for the model building of gauge protected axions. We also find wormhole solutions within two scenarios: (i) an extended global symmetry group within Einstein gravity, and (ii) U(1) wormholes within the low-energy limit of an open String Theory. The former allows us to show that the concept of a global symmetry in General Relativity is somewhat ill-defined. The latter illustrates that for motivated values of the string coupling constant, axions appear to have a quality problem within the open String Theory we consider.

The effects of videos on adult English as a second language student listening comprehension

description: This two-part study employed an experimental design and interviews to examine the effects of videos on adult English as a Second Language (ESL) student listening comprehension. The purpose of the first part of the study was to compare the effects of video in two pre-listening activity conditions on beginner and upper-beginner adult ESL listening comprehension. The participants were 49 Language Instruction for Newcomers to Canada (LINC) students enrolled in two beginner and two upper-beginner ESL classes The beginner classes were randomly assigned either to the audio only (AO) condition or the audio with written script (AW) condition. The upper-beginner classes were similarly assigned to the two conditions, the AO condition or the AW condition. In the AO condition, the students listened to a tape recording of four pre-listening questions prior to viewing the video. In the AW condition, the students listened to the same tape recording and, in addition, were shown the same questions that were printed on large sheets of paper and held up at the front of the class by the teacher. The same pre-test was administered to all four classes. Twelve exercises including pre-listening questions, videos, and comprehension questions were completed. The beginner classes viewed videos from Learning English in the Community LINC 2 (Cameron et al., 1995), and the upper-beginner classes viewed videos from Learning English in the Community LINC 3 (Cameron et al., 1995). The same post-test was administered to all four classes. Results indicated that the written script in the AW condition significantly improved the listening comprehension ability of beginner and upper-beginner adult ESL students. The second part of the study was aimed at gaining insights into the pre-listening questions, the videos, and their value on teaching listening comprehension. All of the students were individually interviewed. Overall the students were positive about the showing of videos as aids for enhancing listening comprehension, the content of the videos, as well as the questions. Some of the students, however, found some of the instruments difficult to understand. They found that the vocabulary was unfamiliar or the speed of delivery was too fast. This lack of comprehension may have affected the results of Part One of the study.

description: This paper explores the scope for system-level agency in new path creation. We identify the roles and challenges for state-led path creation and illustrate them through a case study of a novel and ongoing set of institutional entrepreneurship and system-building activities in the Galicia region of Spain, looking at the practices, relational processes, multilevel lobbying and regulatory change associated with an ambitious initiative to grow a new industry around uncrewed aerial vehicles (UAVs) through anchoring knowledge and legitimacy-building.
