Pricing control as a strategy of urban transportation planning
Creators: name: Hansen, John Hojgaard
Publisher: name: University of British Columbia
Year: 2011

description: For many reasons planners in the past have failed to realize the full potential of the market system as a powerful practical and intellectual tool to be used in urban transportation planning. At a time when there is increasing evidence that past approaches to the urban transportation problem have not yielded the long term solutions that were expected, it is urgent that all alternative strategies be explored. This study addresses itself to one policy course: control of urban transportation through the deliberate use of the market mechanism. The objective of the pricing of urban transportation would be to promote a more socially desirable pattern of usage of the system through a structuring of the demand characteristics - by mode, route, time of travel, and amount of travel. Pricing may thus be used to make the trip-maker aware of, and accountable for, the social costs he incurs in the form of delays due to congestion, noise, air pollution, and so forth, and his travel behaviour would alter accordingly. Because these so-called externalities are, at present not quantifiable in monetary terms, and because of differences in individual utilities, the use of the pricing mechanism cannot displace the political decision-making, but can supplement it. This study is an evaluation of the tool of pricing control in urban transportation planning. The theoretical relationships and the rationale for use of the price mechanism are discussed, and the technical and administrative problems of implementation of a pricing scheme are evaluated. The potential impacts are examined. The practical application of the tool is explored in the context of a case study of traffic in the Lions' Gate Bridge Corridor in Vancouver. There are several compelling advantages to the use of the pricing system for achieving both short-run and long-run objectives. It is extremely flexible, adaptable, incremental, reversible, and most schemes can be implemented at very low capital cost. It can be a strategy for restraint or containment of traffic, or more generally a strategy for directing the patterns of use of the transportation system. But there are serious unanswered questions concerning the limitations of the tool - specifically the income redistribution effects and the overall effectiveness of the pricing mechanism in an increasingly affluent society. There are potential long-term impacts which will remain speculative until we have working urban simulation models. Although the direct application of pricing would be practicable in Canada in only a limited number of clearly defined situations, an understanding of the theoretical concepts will assist in the formulation of specific objectives which may then be pursued using alternate tools more suited to each set of circumstances.
Realizing a tunable honeycomb lattice in ABBA-stacked twisted double bilayer WSe$_2$

description: The ideal honeycomb lattice, featuring sublattice and SU(2) spin rotation symmetries, is a fundamental model for investigating quantum matters with topology and correlations. With the rise of the moiré-based design of model systems, realizing a tunable and symmetric honeycomb lattice system with a narrow bandwidth can open access to new phases and insights. We propose the ABBA-stacked twisted double bilayer WSe$_2$ as a realistic and tunable platform for reaching this goal. Adjusting the twist angle allows the bandwidth and the ratio between hopping parameters of different ranges to be tuned. Moreover, the system's small bandwidth and spin rotation symmetry enable effective control of the electronic structure through an in-plane magnetic field. We construct an extended Hubbard model for the system to demonstrate this tunability and explore possible ordered phases using the Hartree-Fock approximation. We find that at a hole filling of $ν= 2$ (two holes per moiré unit cell), an in-plane magnetic field of a few Tesla can ``dope" the system from a semimetal to a metal. Interactions then drive an instability towards a canted antiferromagnetic insulator ground state. Additionally, we observe a competing insulating phase with sublattice charge polarization. Finally, we discuss the experimental signatures of these novel insulating phases.

description: Snapshot compressive imaging (SCI) systems have gained significant attention in recent years. While previous theoretical studies have primarily focused on the performance analysis of Gaussian masks, practical SCI systems often employ binary-valued masks. Furthermore, recent research has demonstrated that optimized binary masks can significantly enhance system performance. In this paper, we present a comprehensive theoretical characterization of binary masks and their impact on SCI system performance. Initially, we investigate the scenario where the masks are binary and independently identically distributed (iid), revealing a noteworthy finding that aligns with prior numerical results. Specifically, we show that the optimal probability of non-zero elements in the masks is smaller than 0.5. This result provides valuable insights into the design and optimization of binary masks for SCI systems, facilitating further advancements in the field. Additionally, we extend our analysis to characterize the performance of SCI systems where the mask entries are not independent but are generated based on a stationary first-order Markov process. Overall, our theoretical framework offers a comprehensive understanding of the performance implications associated with binary masks in SCI systems.

description: We study the transition time distribution for a particle moving between two wells of a multidimensional potential in the low-noise limit of overdamped Langevin dynamics. Possible transition paths are restricted to a thin tube surrounding the most probable trajectory. We demonstrate that finding the transition time distribution reduces to a one-dimensional problem. The resulting transition time distribution has a universal and compact form. We suggest that transition barriers can be estimated from a single-temperature experiment if both the life times and the transition times are measured.

description: Signal reconstruction from magnitude-only measurements presents a long-standing problem in signal processing. In this contribution, we propose a phase (re)construction method for filter banks with uniform decimation and controlled frequency variation. The suggested procedure extends the recently introduced phase-gradient heap integration and relies on a phase-magnitude relationship for filter bank coefficients obtained from Gaussian filters. Admissible filter banks are modeled as the discretization of certain generalized translation-invariant systems, for which we derive the phase-magnitude relationship explicitly. The implementation for discrete signals is described and the performance of the algorithm is evaluated on a range of real and synthetic signals.

description: We discuss entanglement entropies in 4d interface CFTs based on 4d $\mathcal N=4$ SYM coupled to 3d $\mathcal N=4$ degrees of freedom localized on an interface. Focusing on the entanglement between the two half spaces to either side of the interface, we show that applying the Ryu-Takayanagi prescription in general leads to multiple natural entanglement entropies. We interpret the different entropies as corresponding to different ways of assigning the 3d degrees of freedom localized on the interface to the two half spaces. We contrast these findings with recent discussions of universal relations for entanglement entropies in 2d interface CFTs and formulate generalized relations for 4d interface CFTs which incorporate our results.

description: Heritage science is an interdisciplinary field and successful heritage science research by necessity involves interdisciplinary collaboration between researchers with different disciplinary backgrounds and professional experience. Successful interdisciplinary research is challenging, and many issues have been identified both within and outside heritage science. However, within heritage science there has never been an attempt to do an in-depth study of how communication in interdisciplinary research works in practice. This paper aims to address this gap by providing an in-depth exploration of a case study. We present the analysis of the transcribed recording of a five-hour workshop and follow-up interviews with the workshop participants that took place within the framework of a collaborative heritage science research project. The analysis looks in detail at the dynamics of communication in the context of this meeting, identifying the main topics of conversation and the nature of the transitions between them. We discuss the way in which researchers use different physical scales when thinking about heritage material degradation. We identify key features of interdisciplinary research such as the sense of community and the use of language. Recommendations and insights for future practice are presented.

description: The spectral properties of a non-Hermitian quasi-1D lattice in two of the possible dimerization configurations are investigated. Specifically, it focuses on a non-Hermitian diamond chain that presents a zero-energy flat band. The flat band originates from wave interference and results in eigenstates with a finite contribution only on two sites of the unit cell. To achieve the non-Hermitian characteristics, the system under study presents non-reciprocal hopping terms in the chain. This leads to the accumulation of eigenstates on the boundary of the system, known as the non-Hermitian skin effect. Despite this accumulation of eigenstates, for one of the two considered configurations, it is possible to characterize the presence of non-trivial edge states at zero energy by a real-space topological invariant known as the biorthogonal polarization. This work shows that this invariant, evaluated using the destructive interference method, characterizes the non-trivial phase of the non-Hermitian diamond chain. For the second non-Hermitian configuration, there is a finite quantum metric associated with the flat band. Additionally, the system presents the skin effect despite the system having a purely real or imaginary spectrum. The two non-Hermitian diamond chains can be mapped into two models of the Su-Schrieffer-Heeger chains, either non-Hermitian, and Hermitian, both in the presence of a flat band. This mapping allows to draw valuable insights into the behavior and properties of these systems.

A comparative study of the simulation of daily streamflow sequences
Creators: name: Thambirajah, Percy Anandarajah
Publisher: name: University of British Columbia
Year: 2011

description: Using three years of daily streamflow and meteorological data from the Similkameen watershed at Princeton, B.C., the model parameters of the existing deterministic UBC Budget Model are evaluated. With these model parameters and the available meteorological data, the synthetic streamflow sequences are generated for the other seven years for the Similkameen watershed. These are subsequently compared with the actual flows. A separate statistical stochastic model is developed by using the spectral analysis, and the three years of the same daily flows are decomposed into 30 sub-harmonics or Fourier coefficients. By interpolating the Fourier coefficients and by estimating the anticipated mean annual flows from the snowpack data at Blackwall Peak, the synthetic traces of the daily streamflow sequences are simulated for the other seven years. A first order Markovian model is used to explain the random component. The comparative study is then carried out between the actual daily streamflow sequences and those generated by the deterministic UBC Budget Model and the stochastic spectral model. In comparison with the stochastic spectral model, good fits are obtained with the fixed model parameters of the UBC Budget Model for the sequence of peaks for the simulated hydro-graphs of the intervening years. Since the winter melt factor in the UBC Budget Model was assumed to be a constant for this analysis, some errors occur between the actual and the generated cumulative volumes. With the deterministic periodic component of the spectral model, the reconciliation between the cumulative volumes is fairly well maintained. Since the role of operational hydrology is not concerned with the prediction of actual flows, the stochastic spectral model should be judged on its ability in presenting the designer with a series of synthetic traces that are likely to occur during the lifetime of a particular project.

description: This work addresses human intention identification during physical Human-Robot Interaction (pHRI) tasks to include this information in an assistive controller. To this purpose, human intention is defined as the desired trajectory that the human wants to follow over a finite rolling prediction horizon so that the robot can assist in pursuing it. This work investigates a Recurrent Neural Network (RNN), specifically, Long-Short Term Memory (LSTM) cascaded with a Fully Connected layer. In particular, we propose an iterative training procedure to adapt the model. Such an iterative procedure is powerful in reducing the prediction error. Still, it has the drawback that it is time-consuming and does not generalize to different users or different co-manipulated objects. To overcome this issue, Transfer Learning (TL) adapts the pre-trained model to new trajectories, users, and co-manipulated objects by freezing the LSTM layer and fine-tuning the last FC layer, which makes the procedure faster. Experiments show that the iterative procedure adapts the model and reduces prediction error. Experiments also show that TL adapts to different users and to the co-manipulation of a large object. Finally, to check the utility of adopting the proposed method, we compare the proposed controller enhanced by the intention prediction with the other two standard controllers of pHRI.

description: There have been more hitting streaks in Major League Baseball than we would expect. All batting lines of MLB hitters from 1957-2006 were randomly permuted 10,000 times and the number of hitting streaks of each length from 2 to 100 was measured. The average count of each length streak was then compared to the corresponding total from real-life, when the games were in chronological order. The number of streaks in real-life was significantly higher than over the random permutations. Non-starts (such as pinch-hitting appearances) were removed since these may be unduly reducing the number of streaks in the permutations; the number of streaks in the permutations increased but was still significantly lower than real-life totals. Possible explanations are given for why more streaks have appeared in real-life than we would expect, including possibly the hot hand idea. Contact at trentm@email.unc.edu

Fifteenth-century clergy in the diocese of Norwich : a study of clerical calling, career and culture
Creators: name: Underwood, Emese Caroline Kathleen
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis is a study of the late medieval clergy in the diocese of Norwich. The inquiry examines the career-paths of individual clerks from their schooling through their ordination and appointment to livings and to their achievements. Special attention is paid to patterns of advancement in the Church and to the differences between the career-paths of clerks from diverse educational backgrounds and aspirations, The work is divided into four major parts; each but the last consists of three chapters which deal with topics relevant to the principal theme. As education was a prerequisite for ordination the initial questions are directed towards the problems of schools and schooling. An examination of all known schools and educational benefactions aims to determine the number and type of schools and the range of provisions available to the region. The inquiry next focusses on the availability of patronage and its significance in the lives of the young aspirants who needed moral and financial support to set out on the road to a clerical career. Was there a shortage of priests or was there an oversupply? To find answers to this question the size of the clerical population and the number of benefices and other livings are surveyed and analysed. Attention is next turned towards the manifold nature of clerical careers. This part of the study examines the parish priests at work. It looks at their pastoral and temporal duties, at their finances and living standards, and at their activities at home and within the community. An analysis of book ownership seeks answers to questions touching the cultural interests and development of the clergy. The pastoral duties of the parish priests included extra responsibilities during the time of Lollard infiltration. From the first isolated cases, through the heresy trials of the period and until the end of the century clerks in the diocese were instructed to be alert to beliefs contrary to the Church's teaching and to attempt to eliminate such beliefs in any way they were able. The last part of the dissertation considers the career achievements of the clerks of the diocese during the century and beyond. It is contended here that higher offices in the church were reached by only a few but that for many moderate wealth, influence and learning still meant a significant upward movement socially. The thesis is based on a thorough examination of the Norwich diocesan records and other relevant materials. The methods applied for the analysis of these documents are described in the introductory chapter preceding the main parts of the thesis.

description: The COVID-19 pandemic has highlighted the lack of preparedness of many healthcare systems against pandemic situations. In response, many population-level computational modeling approaches have been proposed for predicting outbreaks, spatiotemporally forecasting disease spread, and assessing as well as predicting the effectiveness of (non-) pharmaceutical interventions. However, in several countries, these modeling efforts have only limited impact on governmental decision-making so far. In light of this situation, the review aims to provide a critical review of existing modeling approaches and to discuss the potential for future developments.

description: Direct photon production in minimum bias d+Cu and d+Au and central Cu+Cu and Au+Au collisions at center of mass energies $\sqrt{s}=62.4$ GeV and 200GeV at RHIC is systematically investigated. We study the jet quenching effect, the medium-induced photon bremsstrahlung and jet-photon conversion in the hot QGP. We account for known cold nuclear matter effects, such as the isospin effect, the Cronin effect, shadowing and cold nuclear matter energy loss. It is shown that at high $p_T$ the nuclear modification factor for direct photons $R_{AA}^γ (p_T) < 1$ is dominated by cold nuclear matter effects and there is no evidence for large cross section amplification due to medium-induced photon bremsstrahlung and jet-photon conversion in the medium. Comparison of numerical simulations to experimental data also rules out large Cronin enhancement and incoherent photon emission in the QGP but the error bars in the current experimental data cannot provide further constraints on the magnitudes of other nuclear matter effects.

description: We propose a class of line-transformed cylindrical cloaks which have easily-realizable constitutive parameters. The scattering properties of such cloaks have been investigated numerically for both transverse-electric (TE) and transverse-magnetic (TM) incidences of plane waves. A line-transformed invisibility cloak with a perfectly electric conducting (PEC) inner boundary is actually a reshaping of a PEC line to which the cloaked object is crushed. The numerical results of near-field distributions and far-field scattering properties have verified the above conclusions. We also investigate the relationship between the constitutive parameters of a line-transformed cloak and the length of the corresponding line. The changing range of constitutive parameters is large when the line is short, while the changing range becomes small when the line is long. The above conclusion provides an efficient way to realize the invisibility cloaks using artificial metamaterials.

description: Introducing a radially dependent magnetic field into Newton's off-center circular orbits potential so as to preserve the $E=0$ dynamical symmetry leads to a unique choice of field that can be identified as the inclusion of a magnetic monopole in the inverse stereographically projected problem. One finds also a phenomenological correspondence with that of the linearly damped Kepler model. The presence of the monopole field deforms the symmetry algebra by a central extension, and the quantum mechanical version of this algebra reveals a number of zero modes equal to that counted using the index theorem of elliptic operators.

description: Methods. We study an equatorial CH observed simultaneously by HINODE and STEREO on July 27, 2007. The HINODE/SP maps are adopted to derive the physical parameters of the photosphere and to research the magnetic field evolution and distribution. The G band and Ca II H images with high tempo-spatial resolution from HINODE/BFI and the multi-wavelength data from STEREO/EUVI are utilized to study the corresponding atmospheric response of different overlying layers. Results. We explore an emerging dipole locating at the CH boundary. Mini-scale arch filaments (AFs) accompanying the emerging dipole were observed with the Ca II H line. During the separation of the dipolar footpoints, three AFs appeared and expanded in turn. The first AF divided into two segments in its late stage, while the second and third AFs erupted in their late stages. The lifetimes of these three AFs are 4, 6, 10 minutes, and the two intervals between the three divisions or eruptions are 18 and 12 minutes, respectively. We display an example of mixed-polarity flux emergence of IN fields within the CH and present the corresponding chromospheric response. With the increase of the integrated magnetic flux, the brightness of the Ca II H images exhibits an increasing trend. We also study magnetic flux cancellations of NT fields locating at the CH boundary and present the obvious chromospheric and coronal response. We notice that the brighter regions seen in the 171 A images are relevant to the interacting magnetic elements. By examining the magnetic NT and IN elements and the response of different atmospheric layers, we obtain good positive linear correlations between the NT magnetic flux densities and the brightness of both G band (correlation coefficient 0.85) and Ca II H (correlation coefficient 0.58).

description: This resource is a single blog post created as part of the Day of Archaeology initiative. The Day of Archaeology project aimed to provide a window into the daily lives of archaeologists from all over the world. The project asked people working, studying or volunteering in the archaeological world to participate in a 'Day of Archaeology' each year by recording their day and sharing it through text, images or video on the Day of Archaeology blog.
The project asked anyone with a personal, professional or voluntary interest in archaeology to get involved, and help highlight the reasons why archaeology is vital to protect the past and inform our futures. The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

description: We study injective endomorphisms of the semigroup $\boldsymbol{B}_ω^{\mathscr{F}}$ with the two-elements family $\mathscr{F}$ of inductive nonempty subsets of $ω$. We describe the elements of the semigroup $\boldsymbol{End}^1_*(\boldsymbol{B}_ω^{\mathscr{F}})$ of all injective monoid endomorphisms of the monoid $\boldsymbol{B}_ω^{\mathscr{F}}$, and show that Green's relations $\mathscr{R}$, $\mathscr{L}$, $\mathscr{H}$, $\mathscr{D}$, and $\mathscr{J}$ on $\boldsymbol{End}^1_*(\boldsymbol{B}_ω^{\mathscr{F}})$ coincide with the relation of equality.

description: Brain-body co-optimization suffers from fragile co-adaptation where brains become over-specialized for particular bodies, hindering their ability to transfer well to others. Evolutionary algorithms tend to discard such low-performing solutions, eliminating promising morphologies. Previous work considered applying MAP-Elites, where niche descriptors are based on morphological features, to promote better search over morphology space. In this work, we show that this approach still suffers from fragile co-adaptation: where a core mechanism of MAP-Elites, creating stepping stones through solutions that migrate from one niche to another, is disrupted. We suggest that this disruption occurs because the body mutations that move an offspring to a new morphological niche break the robots' fragile brain-body co-adaptation and thus significantly decrease the performance of those potential solutions -- reducing their likelihood of outcompeting an existing elite in that new niche. We utilize a technique, we call Pollination, that periodically replaces the controllers of certain solutions with a distilled controller with better generalization across morphologies to reduce fragile brain-body co-adaptation and thus promote MAP-Elites migrations. Pollination increases the success of body mutations and the number of migrations, resulting in better quality-diversity metrics. We believe we develop important insights that could apply to other domains where MAP-Elites is used.

description: In ihrem Beitrag "Die Rolle sozialer Innovationen im Rahmen staatlicher missionsorientierter und transformativer Innovationspolitik" geben Jakob Edler, Katrin Ostertag und Johanna Schuler einen Einblick in aktuelle Entwicklungen der transformationsorientierten Innovationspolitik und betten die Debatte um Soziale Innovation darin ein. Dabei wird der Frage nachgegangen, welche Rolle Soziale Innovationen im Kontext soziotechnischer Transformationsprozesse spielen können und sollen. Formen und Wirkungsmechanismen von Sozialen Innovationen werden in Bezug zu zwei Formen der transformationsorientierten Innovationspolitik - Missionsorientierte Innovationspolitik (MOIP) und Transformative Innovationspolitik (TIP) - gesetzt und diskutiert. Unter Berücksichtigung aktueller Beispiele der Mobilisierung von Sozialen Innovationen in Deutschland werden konzeptionelle Entwicklungen, Chancen und Herausforderung diskutiert und Perspektiven für die fruchtbare Einbindung von Sozialen Innovationen in transformationsorientierte Politik skizziert.
