Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2019

description: Location: JC Room C Students do not engage or perform well when they do not feel socially supported, and they have less opportunities to engage communicatively with each other in our increasingly digital world. This session will help instructors to learn how to create a more compassionate and socially supportive classroom, using evidence-based and evidence-informed mindfulness and compassionate communication techniques. This 90-minute session will blend compassionate communication exercises with mindfulness practices, to support attendees in their own self-awareness as well as their ability to provide and share these practices with their students. Attendees will leave the session with access to a "toolkit for compassionate classrooms" which they can then use in the future, for their own self-compassion and self-care and to support their students' self-care, self-compassion, and learning capacity.

description: A high-resolution nested air quality model, the Weather Research and Forecasting (WRF) model coupled with Chemistry (WRF-Chem), was applied to simulate the ozone concentration in North China from 15 May 2017 to 22 June 2017 during the Atmospheric Pollution and Human Health in a Chinese Megacity (APHH-Beijing) programme measurement campaign and to study an ozone pollution event at the end of May 2017. The model reproduced the meteorological parameters of temperature, relative humidity, wind speed and wind direction well over the period. The key air pollutants of ozone, NOx, SO2, PM2.5 and PM10 are captured reasonable well compared with observations. Results suggest that the ozone simulation matches the observation and simulations of NO2 and SO2 are generally satisfactory using emissions scaled down based on previous studies of anthropogenic emissions changes in China. The model underestimated the peaks in ozone concentration, especially on heavily polluted days, which remain a challenge for modelling ozone and may be attributed to model weaknesses in representing the diurnal cycle of NO and the observed VOC and isoprene. We carried out sensitivity studies investigating how NOx, VOC and isoprene emissions changes affects the simulation of ozone, and improved the ozone simulation of the peaks with 50% increased VOC emissions and doubled isoprene emission. We speculate that the underestimation of VOC emissions or the reactivities of VOC in the model could be reasons for the underestimation of the peaks in ozone concentration and further investigation is needed to improve the simulation of ozone concentrations. We also note that increasing isoprene emission factors can increase the isoprene concentration and improve simulation of ozone concentration, but that simulation of isoprene can still be improved, highlighting the need for investigations of isoprene emissions and model simulation of isoprene. This study describes the effects of different emissions, analyses the weaknesses of the model in simulating ozone and proposes the need for further research on VOC and isoprene simulations.
The Mu2e Experiment -- Searching for Charged Lepton Flavor Violation

description: The Mu2e experiment will search for a Standard Model violating rate of neutrinoless conversion of a muon into an electron in the presence of an aluminum nucleus. Observation of this charged lepton flavor violating process would be an unambiguous sign of new physics. Mu2e will improve upon previous searches for this process by four orders of magnitude. This requires the world's highest-intensity muon beam, a detector system capable of efficiently reconstructing the 105 MeV/c conversion electron signal, and minimizing sensitivity to background events. A pulsed 8 GeV proton beam strikes a target, producing pions that decay into muons. Beam outside the pulse must be suppressed to $< 10^{-10}$ to reduce beam-related backgrounds. The muon beam is guided from the production target along the transport system and onto the aluminum stopping target. Conversion electrons leave the stopping target and propagate inside a solenoidal magnetic field to the tracker and electromagnetic calorimeter. The tracker is a system of straw tube panels filled with Ar/CO$_2$ at 1 atm that tracks particles inside of a solenoidal B-field and measures their momenta with $\sim100$ keV/$c$ resolution to resolve signal events from decay-in-orbit backgrounds. The CsI calorimeter provides $E/p$ and is used to seed the track reconstruction algorithm with $σ_E /E \sim{}10\%$ and $σ_t<500~\rm{ps}$. Additionally, a novel cosmic ray veto with greater than 99.99\% efficiency brings the expected number of background events to fewer than one over three years of running. To normalize the experiment, the stopping target monitor measures the rate of capture photons from muons incident on the stopping target by using a system of high-purity germanium and lanthanum bromide scintillators.

description: The aim of the article is to explore the location and the meaning given to the rainbow flag in places outside the hegemonic center. Through three case studies in the global North and South, held together by a multi-ethnographic approach, as well as a certain theoretical tension between the rainbow flag as a boundary object and/or a floating signifier, we seek to study where the flag belongs, to whom it belongs, with particular focus on how. The three case studies, which are situated in a city in the Global South (Buenos Aires), in a conflict war zone in the Middle East (the West Bank) and in a racialised neighbourhood in the Global North (Sweden), share despite their diversity a peripheral location to hegemonic forms of knowledge production regimes. Central to our analysis is how the rainbow flag is given a multitude of original and radical different meanings that may challenge the colonial/Eurocentric notions which up to a certain extent are embedded in the rainbow flag.

description: Quantum coherence as an asymmetry relative to a translation group generated by a Hermitian operator, is a necessary resource for the quantum parameter estimation. On the other hand, the sensitivity of the parameter estimation is known to be related to the imaginary part of the weak value of the Hermitian operator generating the unitary imprinting of the parameter being estimated. This naturally suggests a question if one can use the imaginary part of the weak value to characterize the coherence as asymmetry. In this work, we show that the average absolute imaginary part of the weak value of the generator of the translation group, maximized over all possible projective measurement bases, can be used to quantify the coherence as asymmetry relative to the translation group, satisfying certain desirable requirements. We argue that the quantifier of coherence so defined, called TC (translationally-covariant) w-coherence, can be obtained experimentally using a hybrid quantum-classical circuit via the estimation of weak value combined with a classical optimization procedure. We obtain upper bounds of the TC w-coherence in terms of the quantum standard deviation, quantum Fisher information, and the imaginary part of the Kirkwood-Dirac quasiprobability. We further obtain a lower bound and derive a relation between the TC w-coherences relative to two generators of translation group taking a form analogous to the Kennard-Weyl-Robertson uncertainty relation.

description: Online communication channels, especially social web platforms, are rapidly replacing traditional ones. Online platforms allow users to overcome physical barriers, enabling worldwide participation. However, the power of online communication bears an important negative consequence --- we are exposed to too much information to process. Too many participants, for example, can turn online public spaces into noisy, overcrowded fora where no meaningful conversation can be held. Here we analyze a large dataset of public chat logs from Twitch, a popular video streaming platform, in order to examine how information overload affects online group communication. We measure structural and textual features of conversations such as user output, interaction, and information content per message across a wide range of information loads. Our analysis reveals the existence of a transition from a conversational state to a cacophony --- a state of overload with lower user participation, more copy-pasted messages, and less information per message. These results hold both on average and at the individual level for the majority of users. This study provides a quantitative basis for further studies of the social effects of information overload, and may guide the design of more resilient online communication systems.

description: In a recent study[Phys. Rev. B 92 (2015) 125427], a hyperspherical approach has been developed to study of few-body fractional quantum Hall states. This method has been successfully applied to the exploration of few boson and fermion problems in the quantum Hall region, as well as the study of inter-Landau level collective excitations. However, the hyperspherical method as it is normally implemented requires a subsidiary (anti-)symmetrization process, which limits its computational effectiveness. The present work overcomes these difficulties and extends the power of this method by implementing a represen- tation of the hyperspherical many-body basis space in terms of Slater determinants of single particle eigenfunctions. A clear connection between the hyperspherical representation and the conventional single particle picture is presented, along with a compact operator representation of the theoretical framework.

description: In this paper, we present an overview of the microjet solutions developed by IEMN/LEMAC-LICS during these last ten years for active flow control in the framework of the GDR \"Control of separations\", the European FP6 \"ADVACT\" program, and different projects from DGA, the aeronautic foundation, EADS foundation, and CNRT-R2A. The work within these different research projects has been made in collaboration with the major French and European aeronautic and automobile industrials. The IEMN/LEMAC-LICS solutions are based on Micro-Magneto-Mechanical Systems (MMMS) and concern integrated devices delivering pulsed microjets, continuous microjets with bistable ON-OFF actuation, and synthetic microjets. These devices were combined in arrays of 8 to 30 elements distributed near the leading edge of a physical model of air wing, within an engine blade, inside a S-duct, around an engine exhaust and at the rear end of a Ahmed car model. Several wind tunnel experiments were made for separation control, and aero-acoustic control. It was demonstrated that the microjets satisfied the functional specifications defined by the industrial partners. Efficient flow control was obtained. MMMS actuators have demonstrated a good robustness in severe wind tunnel environments (temperature, compressibility, humidity, structural vibrations...).

description: It is pointed out that the ground state of n neutrons and n protons in a single-j shell, interacting through an isoscalar (T=0) pairing force, is not paired, J=0, but rather spin-aligned, J=n. This observation is explained in the context of a model of isoscalar P (J=1) pairs, which is mapped onto a system of p bosons, leading to an approximate analytic solution of the isoscalar-pairing limit in jj coupling.

description: The mechanism behind the shaping of bipolar planetary nebulae is still poorly understood. Accurately tracing the molecule-rich equatorial regions of post-AGB stars can give valuable insight into the ejection mechanisms at work. We investigate the physical conditions, structure and velocity field of the dense molecular region of the planetary nebula NGC 6302 by means of ALMA band 7 interferometric maps. The high spatial resolution of the $^{12}$CO and $^{13}$CO J=3-2 ALMA data allows for an analysis of the geometry of the ejecta in unprecedented detail. We built a spatio-kinematical model of the molecular region with the software SHAPE and performed detailed non-LTE calculations of excitation and radiative transfer with the SHAPEMOL plug-in. We find that the molecular region consists of a massive ring out of which a system of fragments of lobe walls emerge and enclose the base of the lobes visible in the optical. The general properties of this region are in agreement with previous works, although the much greater spatial resolution of the data allows for a very detailed description. We confirm that the mass of the molecular region is 0.1 M$_{\odot}$. Additionally, we report a previously undetected component at the nebular equator, an inner, younger ring inclined $\sim$60$^\circ$ with respect to the main ring, showing a characteristic radius of 7.5$\times$10$^{16}$ cm, a mass of 2.7$\times$10$^{-3}$ M$_{\odot}$, and a counterpart in optical images of the nebula. This inner ring has the same kinematical age as the northwest optical lobes, implying it was ejected approximately at the same time, hundreds of years after the ejection of the bulk of the molecular ring-like region. We discuss a sequence of events leading to the formation of the molecular and optical nebulae, and briefly speculate on the origin of this intriguing inner ring.

description: The authorship attribution is a problem of considerable practical and technical interest. Several methods have been designed to infer the authorship of disputed documents in multiple contexts. While traditional statistical methods based solely on word counts and related measurements have provided a simple, yet effective solution in particular cases; they are prone to manipulation. Recently, texts have been successfully modeled as networks, where words are represented by nodes linked according to textual similarity measurements. Such models are useful to identify informative topological patterns for the authorship recognition task. However, there is no consensus on which measurements should be used. Thus, we proposed a novel method to characterize text networks, by considering both topological and dynamical aspects of networks. Using concepts and methods from cellular automata theory, we devised a strategy to grasp informative spatio-temporal patterns from this model. Our experiments revealed an outperformance over traditional analysis relying only on topological measurements. Remarkably, we have found a dependence of pre-processing steps (such as the lemmatization) on the obtained results, a feature that has mostly been disregarded in related works. The optimized results obtained here pave the way for a better characterization of textual networks.

description: In model-driven engineering (MDE), UML class diagrams serve as a way to plan and communicate between developers. However, it is complex and resource-consuming. We propose an automated approach for the extraction of UML class diagrams from natural language software specifications. To develop our approach, we create a dataset of UML class diagrams and their English specifications with the help of volunteers. Our approach is a pipeline of steps consisting of the segmentation of the input into sentences, the classification of the sentences, the generation of UML class diagram fragments from sentences, and the composition of these fragments into one UML class diagram. We develop a quantitative testing framework specific to UML class diagram extraction. Our approach yields low precision and recall but serves as a benchmark for future research.

description: Introduction. Since Regione Veneto suspended compulsory vaccination for children in 2008, and because of an increasing disaffection of parents to the vaccine practice, the vaccination rates have been slowly but steadily decreasing. The aim of this study was to analyze internal and external factors of immuniza- tion reduction and to implement potential solutions of the prob- lem. Methods. Servizio Igiene e Sanita? Pubblica of ULSS 12 Venezi- ana (SISP ? Hygiene and Public Health Service) analyzed and addressed both, the reasons of parents who do not vaccinate their children and the internal problems regarding vaccination clinics management, information to families, procedures and guidelines and, in general, the communication skills of the vaccination staff. Results. A positive trend in vaccination rates was observed, espe- cially in Venice historical centre. Moreover the staff reported a better working atmosphere and benefit from sharing common goals and procedures, even though the workforce was reduced of about 30% in terms of equivalent unit (EU). Discussion. The continuous quality improvement method fol- lowed in this experience led to a steady increase in vaccination coverage in all territorial clinics, to a better adhesion of guide- lines and standard operating procedures and to a general pro- fessional empowerment of SISP staff. The service now offered to the population is better and more efficient, since the workforce has been reduced. Future goals are to improve information about vaccinations among the population.

Creators: name: Barokka, Khairani
Publisher: name: Goldsmiths, University of London

description: In delving into how inconsistently Annah, the young subject of Paul Gauguin’s painting Annah la Javanaise (c. 1893-4), is written about in terms of historical facts, this work queries assumptions of ablenormativity in narratives surrounding them. This multidisciplinary thesis presents scenarios in visual art and creative writing, with artistic process-as-research as primary methodology, presenting Annah outside of their usual context, and as a pained body—prefaced by how such ‘unreliable’ narratives echo the jumble of statements surrounding them; in turn using inconsistent, sometimes clashing ‘facts’ about Annah in these narratives, in order to negate the potential violence of declaring one truth for them, emphasising the liminality of information—in order to explicate what norms these portrayals rupture. Drawing from and linking the work of Sara Ahmed (2002, 2004, 2013), Yasmin Gunaratnam (2013), disability and chronic pain scholars such as Alison Kafer (2013) and Alyson Patsavas (2014), Indonesian feminist and disability scholarship such as Slamet Amex Thohari’s (2013) work, and Ann Laura Stoler’s (1995, 2016) theories, particularly in augmenting the latter’s work on colonial Southeast Asia and imperial duress, this thesis places into relief the functions of compulsory ablenormativity regarding certain young, brown girls of supposed Southeast Asian descent. It exposes how elements of white supremacy and of patriarchy are linked to such ablenormative visual assumptions, and the real, often devastating effects such interpretations have on Southeast Asian women and girls today: ablenormativity, in interpretations of visual culture, as imperial duress. It argues for (a) decolonial, pained-aware readings, and (b) soulbody readings as methods of dismantling the affect structures of imperial duress.

description: Unsupervised learning and supervised learning are key research topics in deep learning. However, as high-capacity supervised neural networks trained with a large amount of labels have achieved remarkable success in many computer vision tasks, the availability of large-scale labeled images reduced the significance of unsupervised learning. Inspired by the recent trend toward revisiting the importance of unsupervised learning, we investigate joint supervised and unsupervised learning in a large-scale setting by augmenting existing neural networks with decoding pathways for reconstruction. First, we demonstrate that the intermediate activations of pretrained large-scale classification networks preserve almost all the information of input images except a portion of local spatial details. Then, by end-to-end training of the entire augmented architecture with the reconstructive objective, we show improvement of the network performance for supervised tasks. We evaluate several variants of autoencoders, including the recently proposed "what-where" autoencoder that uses the encoder pooling switches, to study the importance of the architecture design. Taking the 16-layer VGGNet trained under the ImageNet ILSVRC 2012 protocol as a strong baseline for image classification, our methods improve the validation-set accuracy by a noticeable margin.

description: We consider a modified Nagel-Schreckenberg (NS) model in which drivers do not decelerate if their speed is smaller than the headway (number of empty sites to the car ahead). (In the original NS model, such a reduction in speed occurs with probability $p$, independent of the headway, as long as the current speed is greater than zero.) In the modified model the free-flow state (with all vehicles traveling at the maximum speed, $v_{max}$) is {\it absorbing} for densities $ρ$ smaller than a critical value $ρ_c = 1/(v_{max} + 2)$. The phase diagram in the $ρ- p$ plane is reentrant: for densities in the range $ρ_{c,
Resource efficient redundancy using quorum-based cycle routing in optical networks

description: In this paper we propose a cycle redundancy technique that provides optical networks almost fault-tolerant point-to-point and multipoint-to-multipoint communications. The technique more importantly is shown to approximately halve the necessary light-trail resources in the network while maintaining the fault-tolerance and dependability expected from cycle-based routing. For efficiency and distributed control, it is common in distributed systems and algorithms to group nodes into intersecting sets referred to as quorum sets. Optimal communication quorum sets forming optical cycles based on light-trails have been shown to flexibly and efficiently route both point-to-point and multipoint-to-multipoint traffic requests. Commonly cycle routing techniques will use pairs of cycles to achieve both routing and fault-tolerance, which uses substantial resources and creates the potential for underutilization. Instead, we intentionally utilize redundancy within the quorum cycles for fault-tolerance such that almost every point-to-point communication occurs in more than one cycle. The result is a set of cycles with 96.60% - 99.37% fault coverage, while using 42.9% - 47.18% fewer resources.

description: The formation of microdomains, also called rafts, in biomembranes can be attributed to the surface tension of the membrane. In order to model this phenomenon, a model involving a coupling between the local composition and the local curvature was proposed by Seul and Andelman in 1995. In addition to the familiar Cahn-Hilliard/Modica-Mortola energy, there are additional `forces' that prevent large domains of homogeneous concentration. This is taken into account by the bending energy of the membrane, which is coupled to the value of the order parameter, and reflects the notion that surface tension associated with a slightly curved membrane influences the localization of phases as the geometry of the lipids has an effect on the preferred placement on the membrane. The main result of the paper is the study of the $Γ$-convergence of this family of energy functionals, involving nonlocal as well as negative terms. Since the minimizers of the limiting energy have minimal interfaces, the physical interpretation is that, within a sufficiently strong interspecies surface tension and a large enough sample size, raft microdomains are not formed.

description: The influence of the spin-orbit coupling (SOC) on the magnetic dipole term $T_α$ is studied across a range of systems in order to check whether the $T_α$ term can be eliminated from analysis of x-ray magnetic circular dichroism spectra done via the spin moment sum rule. Fully relativistic Korringa-Kohn-Rostoker (KKR) Green function calculations for Co monolayers and adatoms on Cu, Pd, Ag, Pt, and Au (111) surfaces were performed to verify whether the sum over magnetic dipole terms $T_{x}+T_{y}+T_{z}$ is zero and whether the angular dependence of the \ta\ term goes as $3\cos^{2}θ-1$. It follows that there are circumstances when the influence of the SOC on $T_α$ cannot be neglected even for 3$d$ atoms, where the SOC is nominally small. The crucial factor appears to be the dimensionality of the system: for 3$d$ adatoms, the influence of SOC on $T_α$ can be significant while for monolayers it is always practically negligible. Apart from the dimensionality, hybridization between adatom and substrate states is also important: small hybridization enhances the importance of the SOC and vice versa.

description: We present the first set of benchmark problems for phase field models that are being developed by the Center for Hierarchical Materials Design (CHiMaD) and the National Institute of Standards and Technology (NIST). While many scientific research areas use a limited set of well-established software, the growing phase field community continues to develop a wide variety of codes and lacks benchmark problems to consistently evaluate the numerical performance of new implementations. Phase field modeling has become significantly more popular as computational power has increased and is now becoming mainstream, driving the need for benchmark problems to validate and verify new implementations. We follow the example set by the micromagnetics community to develop an evolving set of benchmark problems that test the usability, computational resources, numerical capabilities and physical scope of phase field simulation codes. In this paper, we propose two benchmark problems that cover the physics of solute diffusion and growth and coarsening of a second phase via a simple spinodal decomposition model and a more complex Ostwald ripening model. We demonstrate the utility of benchmark problems by comparing the results of simulations performed with two different adaptive time stepping techniques, and we discuss the needs of future benchmark problems. The development of benchmark problems will enable the results of quantitative phase field models to be confidently incorporated into integrated computational materials science and engineering (ICME), an important goal of the Materials Genome Initiative.

We obtained the cluster's distance from the Sun as 1721+/-41 pc and log (age)= 9.85+/-0.05 at Solar metallicity. The relaxation time of the cluster is smaller than the estimated cluster age which suggests that the cluster is dynamically relaxed. Our results agree with the values mentioned in the literature. We also determined the cluster's apex coordinates as (281.88 deg, -44.76 deg) using AD-diagram method. Other kinematical parameters like space velocity components, cluster center and elements of Solar motion etc. have also been computed.

description: In this paper we propose a generalized R redundancy cycle technique that provides optical networks almost fault-tolerant communications. More importantly, when applied using only single cycles rather than the standard paired cycles, the generalized R redundancy technique is shown to almost halve the necessary light-trail resources in the network while maintaining the fault-tolerance and dependability expected from cycle-based routing. For efficiency and distributed control, it is common in distributed systems and algorithms to group nodes into intersecting sets referred to as quorum sets. Optimal communication quorum sets forming optical cycles based on light-trails have been shown to flexibly and efficiently route both point-to-point and multipoint-to-multipoint traffic requests. Commonly cycle routing techniques will use pairs of cycles to achieve both routing and fault-tolerance, which uses substantial resources and creates the potential for underutilization. Instead, we intentionally utilize R redundancy within the quorum cycles for fault-tolerance such that every point-to-point communication pairs occur in at least R cycles. The result is a set of R = 3 redundant cycles with 93.23-99.34% fault coverage even with two simultaneous faults all while using 38.85-42.39% fewer resources.

Biological and molecular analysis of important agricultural pest species in southern Australia: Penthaleus species and Halotydeus destructor

description: Blue oat mite species, Penthaleus spp. (Acari: Penthaleidae), and the redlegged earth mite, Halotydeus destructor (Tucker) (Acari: Penthaleidae), are some of the most serious and widespread agricultural pests in southern Australia. Management of these mites has been complicated by the recent discovery of three cryptic species of Penthaleus, whereas prior research has assumed a single species. The species differ markedly in their distribution, plant preferences and response to pesticides. This thesis looks at various aspects of the biology, ecology and molecular analyses of earth mites with particular emphasis on agricultural control.I tested the initiation of diapause egg production in mites using field and shade-house experiments. Halotydeus destructor has a very different diapause response from Penthaleus species. Thus, carefully timed spring sprays are unlikely to be effective against Penthaleus spp., highlighting the importance of correctly distinguishing earth mite species before implementing control strategies. There is also variation in diapause induction among the three Penthaleus spp. that could contribute to their relative distributions and pest status. I examined the effects of different plant hosts on the persistence and reproduction of earth mites. The results are consistent with field observations that mite species differ in their host plants. For all species, pasture is a suitable host and lentils are generally a poor host plant. Canola, ox-tongue, and a mixture of wheat and oats differ in their suitability as long-term hosts for each mite species. This information is important for developing more sustainable management practices, such as weed management and crop rotations. Competitive interactions between earth mites were also investigated in the field and the laboratory over a number of seasons. In order to make valid conclusions with an applied implication, competition was examined on four different plant treatments: pasture, canola, wheat/oats and ox-tongue. I showed that close competition exists between mite species and that competitive interactions differ temporally and on different plant types. Finally, I undertook biochemical analysis of Penthaleus spp. for the development of a rapid and simple field test that could be used by agronomists and farmers to distinguish the different mite species on individual properties. This would allow appropriate control strategies to be devised, as well as reduce the ineffectual application of pesticides. Using mostly immunological techniques, I revealed important information about the complex nature of the Penthaleus group, the similarity between the three species, as well as develop methods for isolating and characterising species-specific proteins. Directions this work may take in future studies are also discussed.

description: Excitation of nonlinear ion acoustic wave (IAW) by an external electric field is demonstrated by Vlasov simulation. The frequency calculated by the dispersion relation with no damping is verified much closer to the resonance frequency of the small-amplitude nonlinear IAW than that calculated by the linear dispersion relation. When the wave number $ kλ_{De} $ increases, the linear Landau damping of the fast mode (its phase velocity is greater than any ion's thermal velocity) increases obviously in the region of $ T_i/T_e < 0.2 $ in which the fast mode is weakly damped mode. As a result, the deviation between the frequency calculated by the linear dispersion relation and that by the dispersion relation with no damping becomes larger with $kλ_{De}$ increasing. When $kλ_{De}$ is not large, such as $kλ_{De}=0.1, 0.3, 0.5$, the nonlinear IAW can be excited by the driver with the linear frequency of the modes. However, when $kλ_{De}$ is large, such as $kλ_{De}=0.7$, the linear frequency can not be applied to exciting the nonlinear IAW, while the frequency calculated by the dispersion relation with no damping can be applied to exciting the nonlinear IAW.

Mediterranei italiani. Il Mediterraneo nelle scritture di viaggio dell’Italia preunitaria
Creators: name: Serafini, Elisabetta
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2016

description: In the Mediterranean of the Nineteenth century the Italian peninsula seems to have played a marginal role, in which the political fragmentation did not help. Starting from the unification, the numerous studies that tried to rebuild the Italian presence beyond national borders have emphasized that the Italians who crossed the ancient seawater in those sixty years were mostly exiles, escaping conservative persecution. In these cases not only men travelled, but also ideas. But those studies also tried to build Italy's Mediterranean history – of which the “excellent” nineteenth-century migrations had been key steps – with the aim of legitimizing the Italian presence in the mare nostrum. Looking at the Peninsula’s Mediterranean perspective, this essay wants to investigate – through travel writings – in what terms that space was experienced by the travellers before the unification.

The Future of Chicago’s Transit-Oriented Development: A Quantitative Analysis of Ridership by ACS and Zoning Variables
Creators: name: Lopez, Barrett
Publisher: name: University of Chicago
Year: 2022

description: This thesis seeks to develop a comprehensive understanding of chronically underused stations throughout the Chicago Transit Authority’s rail network. I will specifically focus on land use, demographic, and built environment indicators within block groups at a half-mile radius as independent variables, studying these variables with all rail stations in the CTA system from 2016-2019. Through the use of negative binomial multivariate regression models with American Community Survey (ACS) block-group level and City of Chicago Zoning Ordinance data, I seek to discern common trends shaping the current status of the system’s use with a distinct focus on the large variety of ridership quantities in the system. Results show that demographic indicators of white population and employment, were significantly correlated with heightened ridership at a system-wide level. Significant zoning types offer unique contributions to ridership assumptions, as Downtown Core (DC), Private Development (PD), and Residential Single-Unit (RS) districts see estimated increased ridership proportional to their areas proximate to stations; the areas of Transit (T) and Neighborhood Commercial (C1) districts show negative estimates. Finally, the model suggests highly significant positive coefficients buildings finished within the eras of post-2000 and 1940-1969. Despite the existence of multiple significant regressors among each type of presumed transit effectors, high standard errors deter certainty of conclusions in each highly significant variable in the final model, which uses 35 unique regressors. This analysis should not be interpreted causally, but the recognition of significant zoning, demographic, and built environment coefficients in a suggest intricate relations to ridership at the system-wide level.

description: We present a feedback protocol that is able to confine a system to a single micro-state without heat dissipation. The protocol adjusts the Hamiltonian of the system in such a way that the Bayesian posterior distribution after measurement is in equilibrium. As a result, the whole process satisfies feedback reversibility -- the process is indistinguishable from its time reversal -- and assures the lowest possible dissipation for confinement. In spite of the whole process being reversible it can surprisingly be implemented in finite time. We illustrate the idea with a Brownian particle in a harmonic trap with increasing stiffness and present a general theory of reversible feedback confinement for systems with discrete states.

description: Subject of our study it is the accelerated expansion of the large scale universe, where a varying ghost dark energy can take the role of the dark energy. The model of the varying ghost dark energy considered in this work it is a phenomenological modification of the ghost dark energy. Recently, three other phenomenological models of the varying ghost dark energy have been suggested and the model considered in this work will complete the logical chain of considered modifications. The best fit of theoretical results to the luminosity distance, has been used to obtain preliminary constraints on the parameters of the models. This does help us to reduce amount of discussion. On the other hand, detailed comparison of theoretical results with observational data has been left as a subject of another discussion elsewhere. Moreover, a look to considered models via $Om$ and statefinder hierarchy analysis is presented and discussed for different forms of interaction between the varying ghost dark energy and cold dark matter.
