description: We present a holographic model of QCD with a first order chiral restoration phase transition with chemical potential, mu. The first order behaviour follows from allowing a discontinuity in the dual description as the quarks are integrated out below their constituent mass. The model predicts a deconfined yet massive quark phase at intermediate densities (350 MeV< mu <500 MeV), above the nuclear density phase, which has a very stiff equation of state and a speed of sound close to one. We also include a holographic description of a colour superconducting condensate in the chirally restored vacuum and study the resulting equation of state. They provides a well behaved first order transition from the deconfined massive quark phase at very high density (mu>500 MeV). We solve the Tolman-Oppenheimer-Volkoff equations with the resulting equations of state and find stable hybrid stars with quark cores. We compute the tidal deformability for these hybrid stars and show they are consistent with LIGO/Virgo data on a neutron star collision. Our holographic model shows that quark matter could be present at the core of such compact stars.

description: We discuss symmetric quantum measurements and the associated covariant observables modelled, respectively, as instruments and positive-operator-valued measures. The emphasis of this work are the optimality properties of the measurements, namely, extremality, informational completeness, and the rank-1 property which contrast the complementary class of (rank-1) projection-valued measures. The first half of this work concentrates solely on finite-outcome measurements symmetric w.r.t. finite groups where we derive exhaustive characterizations for the pointwise Kraus-operators of covariant instruments and necessary and sufficient extremality conditions using these Kraus-operators. We motivate the use of covariance methods by showing that observables covariant with respect to symmetric groups contain a family of representatives from both of the complementary optimality classes of observables and show that even a slight deviation from a rank-1 projection-valued measure can yield an extreme informationally complete rank-1 observable. The latter half of this work derives similar results for continuous measurements in (possibly) infinite dimensions. As an example we study covariant phase space instruments, their structure, and extremality properties.
Discrete phase space and continuous time relativistic quantum mechanics I: Planck oscillators and closed string-like circular orbits

Publisher: name: arXiv

Subjects: subject: Quantum Physics (quant-ph)

description: The discrete phase space continuous time representation of relativistic quantum mechanics involving a characteristic length $l$ is investigated. Fundamental physical constants such as $\hbar$, $c$, and $l$ are retained for most sections of the paper. The energy eigenvalue problem for the Planck oscillator is solved exactly in this framework. Discrete concircular orbits of constant energy are shown to be circles $S^{1}_{n}$ of radii $2E_n =\sqrt{2n+1}$ within the discrete (1 + 1)-dimensional phase plane. Moreover, the time evolution of these orbits sweep out world-sheet like geometrical entities $S^{1}_{n} \times \mathbb{R} \subset \mathbb{R}^2$ and therefore appear as closed string-like geometrical configurations. The physical interpretation for these discrete orbits in phase space as degenerate, string-like phase cells is shown in a mathematically rigorous way. The existence of these closed concircular orbits in the arena of discrete phase space quantum mechanics, known for the non-singular nature of lower order expansion $S^{\#}$ matrix terms, was known to exist but has not been fully explored until now. Finally, the discrete partial difference-differential Klein-Gordon equation is shown to be invariant under the continuous inhomogeneous orthogonal group $\mathcal{I} [O(3,1)]$ .

Helicopter logging productivity in dispersed and aggregate partial retention systems
Creators: name: Lyons, Charles Kevin
Publisher: name: University of British Columbia
Year: 2009

description: This study evaluated several factors that affect helicopter logging productivity in partial cutting operations. The harvest treatments applied to the 4 units in this study were 75% aggregated retention, 40% dispersed retention, 40% aggregated retention, and 15% dispersed retention. The flight record data included turn time, turn mass, and the number of logs per turn for each unit, while there was only limited detailed sampling of the in-unit turn time elements, and of turn merchantable volume to mass ratios. The treatments applied in this study did not appear to have a dramatic effect on helicopter productivity. There was little correlation detected between turn time and turn mass, turn time and the number of logs per turn, and turn mass and the number of logs per turn. The distance to the unit from the landing appeared to have the greatest affect on total turn time, while the lifting component of the in-unit time dominated the variation of the in-unit timing. The turn cycles with choker drops and aborts increased the average total turn time in units 2 and 5 by less than 7 %. Turn mass did not vary greatly between the units, and this is attributed to the ability of the hooktenders to compensate for the varying conditions. Regression equations were developed to estimate total turn time and turn volume. These equations demonstrate that productivity increases with reduced horizontal distance to the unit, increased log size, and increased volume of merchantable wood per unit mass. However, more detailed sampling is required to identify nonlinear relationships between log volume and turn volume, and horizontal distance and turn time. Also more research is needed to identify factors that link turn time and turn volume to stand conditions at higher levels of retention.

description: We present our method for tackling the legal case retrieval task of the Competition on Legal Information Extraction/Entailment 2019. Our approach is based on the idea that summarization is important for retrieval. On one hand, we adopt a summarization based model called encoded summarization which encodes a given document into continuous vector space which embeds the summary properties of the document. We utilize the resource of COLIEE 2018 on which we train the document representation model. On the other hand, we extract lexical features on different parts of a given query and its candidates. We observe that by comparing different parts of the query and its candidates, we can achieve better performance. Furthermore, the combination of the lexical features with latent features by the summarization-based method achieves even better performance. We have achieved the state-of-the-art result for the task on the benchmark of the competition.

description: We extensively study the phase diagram of a diblock copolymer melt confined in a cylindrical nanopore using real-space self-consistent mean-field theory. We discover a rich variety of new two-dimensional equilibrium structures that have no analog in the unconfined system. These include non-hexagonally coordinated cylinder phases and structures intermediate between lamellae and cylinders. We map the stability regions and phase boundaries for all the structures we find. As the pore radius is decreased, the pore accommodates fewer cylindrical domains and structural transitions occur as cylinders are eliminated. Our results are consistent with experiments, but we also predict phases yet to be observed.

description: Basic physics of drift-wave turbulence and zonal flows has long been studied within the framework of wave-kinetic theory. Recently, this framework has been re-examined from first principles, which has led to more accurate yet still tractable "improved" wave-kinetic equations. In particular, these equations reveal an important effect of the zonal-flow "curvature" (the second radial derivative of the flow velocity) on dynamics and stability of drift waves and zonal flows. We overview these recent findings and present a consolidated high-level picture of (mostly quasilinear) zonal-flow physics within reduced models of drift-wave turbulence.

Diaphragm injury in chronic respiratory disease
Creators: name: MacGowan, Nori A.
Publisher: name: University of British Columbia
Year: 2009

description: Diaphragm injury may occur in chronic respiratory disease due to factors which increase the workload, cause weakness, or reduce the efficiency of the ventilatory pump. Diaphragm injury has been shown in many animal models of respiratory overload, but similar research in humans is limited. The purpose of this thesis was to investigate diaphragm injury in individuals who may experience diaphragm overload due to chronic respiratory disease. Diaphragm biopsies were obtained from twenty-one individuals going for thoracotomy surgery, and from thirty-three individuals post-mortem. In the thoracotomy study, biopsies were quick frozen (n=18) or formalin-fixed (n=3). Thick sections (10 μm) were stained with H & E. Macrophages were identified in thin sections (6 μm) using immunohistochemistry and monoclonal antibodies (Ber- MAC3, DAKO Canada Corp.). In the post-mortem study, biopsies were fixed in 10% formalin, then stained with H & E and Masson's trichrome. Area fractions of normal muscle, abnormal muscle and connective tissue were determined by point counting diaphragm cross-sections from both thoracotomy and post-mortem subjects. Image analysis was used to determine the number of macrophages in diaphragm cross-sections from thoracotomy subjects. Subjects in the thoracotomy study had airflow obstruction ranging from mild to severe, and had relatively homogeneous clinical characteristics. This study showed an inverse relationship between the proportion of abnormal muscle and the % predicted FEV₁ (r = -0.53, p < 0.01), and a direct relationship between the proportion of normal muscle and the % predicted FEV₁ (r = 0.37, p < 0.05). There was no relationship between the number of macrophages and the % predicted FEV₁. Subjects in the post-mortem study were heterogeneous in their clinical characteristics. This study showed a trend towards a direct relationship between the proportion of abnormal muscle and the presence of chronic respiratory disease (p=.065), and no relationship between the proportion of abnormal muscle and other clinical factors (gender, age, body mass index, presence of acute respiratory disease). We conclude from the first study that abnormal morphology is present in the diaphragm and is related to the severity of airflow obstruction in a fairly homogeneous sample of individuals going for thoracotomy surgery. We conclude from the second study that further study with a larger sample of individuals who have died of various causes may provide evidence of a relationship between abnormal diaphragm morphology and the presence of chronic respiratory disease.
Privacy or utility? how to preserve both in outlier analysis
Creators: name: Asif, Hafiz
Publisher: name: No Publisher Supplied
Year: 2021

description: Data analysts use outlier analysis to discover non-conforming patterns in data to gen- erate actionable insights. It is an incredibly useful approach, but like all data-driven approaches, it raises privacy-related serious ethical and legal concerns when data is about peoples’ information. Is it possible to accurately analyze data for outliers while protecting the privacy of people whose data we analyze? In this dissertation, we explicate methods to answer this question for the most practically relevant case, where outliers are defined in a data-dependent way and current privacy methods such as differential privacy fail to achieve practically meaningful utility.To define what it means to protect privacy in outlier analysis, we conceptualize sensitive privacy — it not only admits eﬀicient algorithmic constructions but is also amenable to analysis. We introduce novel constructions to develop sensitively private mechanisms to accurately identify outliers, and to compile low-accuracy differentially private mechanisms into high-accuracy sensitively private mechanisms. Furthermore, to address the lack of a principled approach to private outlier analysis, we provide a framework to help a data analyst identify the right problem-specification and a practical solution for her application.Finally, we develop mechanisms — which guarantee privacy and practically mean- ingful utility — to identify (β,r)-anomalies as well as covid-19 hotspots (an outlying event). An extensive empirical evaluation of these private mechanisms over a range of real-world datasets and use cases overwhelmingly supports the effectiveness of our approach.

description: The easily tunable emission of halide perovskite nanocrystals throughout the visible spectrum makes them an extremely promising material for light-emitting applications. Whereas high quantum yields and long-term colloidal stability have already been achieved for nanocrystals emitting in the red and green spectral range, the blue region currently lags behind, with low quantum yields, broad emission profiles and insufficient colloidal stability. In this work, we present a facile synthetic approach for obtaining two-dimensional CsPbBr3 nanoplatelets with monolayer-precise control over their thickness, resulting in sharp photoluminescence and electroluminescence peaks with a tunable emission wavelength between 432 and 497 nm due to quantum confinement. Subsequent addition of a PbBr2-ligand solution repairs surface defects likely stemming from bromide and lead vacancies in a sub-ensemble of weakly emissive nanoplatelets. The overall photoluminescence quantum yield of the blue-emissive colloidal dispersions is consequently enhanced up to a value of 73+-2 %. Transient optical spectroscopy measurements focusing on the excitonic resonances further confirm the proposed repair process. Additionally, the high stability of these nanoplatelets in films and to prolonged UV light exposure is shown.

Subjects: scalability, robustness testing, public challenge

description: Driven by use case scenarios, WP5 aims to evaluate the results obtained in WP 2 (Policy and Transparency Framework), WP 3 (Big Data Policy Engine), and WP 4 (User Interaction) under conditions. More specifically, the goal of T5.3 Public challenges is to expose the developed system and its components to public hacking challenges, which would, together with the internal backend scalability and robustness testing performed in WP3 (D3.3 and D3.5) and frontend testing in WP4 (D4.2 and D4.4), provide the necessary feedback for further development of the SPECIAL platform. To guarantee the robustness of our architecture, such tests must focus on ensuring that both the individual components and the infrastructure as a whole are capable of sharing data only with authorized parties, while guaranteeing that policies and regulations are being adhered to. This means that the challenges should span beyond just penetration testing, and involve other aspects of the system, be it technical or legal, highlighting any limitations. Moreover, WP 6 (Collaboration, Dissemination & Standardisation) will organize public workshops to present and discuss such limitations and obtain input with respect to possible additional challenges. The experiences gained from all these activities will be merged, generalized, and translated into a set of methodological guidelines for future implementations.
Understanding the Other in the Psychotherapeutic Relationship

Publisher: name: Journal of Applied Hermeneutics
Year: 2019

description: Psychotherapy is often described as the art and science of endeavouring to understand the other. The difficulties inherent in understanding have contributed to psychotherapy being described as “the impossible profession” (Malcolm, 1980). In this article I explore the difficulties of understanding in the psychotherapy relationship, drawing on the hermeneutic phenomenological thinking of Hans-Georg Gadamer, Martin Heidegger, and Maurice Merleau-Ponty in particular, as well as the thinking of psychotherapy writers. I note the relationship between the spoken word and silence, whereby words emerge from silence and contemplation. Further, that understanding is enhanced by being willing to place oneself continually in the position of apprentice learner, by remaining open and able to tolerate uncertainty and not knowing and, to closely attend to one’s own and to the other’s emotional states as they manifest in the work. In describing a clinical case from my practice, I illustrate the complexity and difficulties of doing any or all of these.

Slow, Subjective and Stressful: A Guide to Canada's Asylum System
Creators: name: Falconer, Robert
Publisher: name: The School of Public Policy Publications
Year: 2019

description: This paper is the second in a series of papers on Canada’ asylum system. The first paper, Ping-pong Asylum, took us to the border, and outlined the issues behind the recent influx of people crossing there. This paper focuses on what happens to those people, and other asylum seekers, once they are inside Canada. The analysis shows that Canada’s asylum system is not an easy path to living in Canada or gaining citizenship. Asylum seekers or Canadian citizens who think asylum is a form of queue jumping or circumventing normal immigration pathways are mistaken. It is a complex web of agencies and steps. This complexity partially results from the due process granted to asylum seekers. It is also the result of evolving bureaucracies and case management systems impacted by political agendas and sudden surges in asylum seeker numbers. This complex system does not lend itself well to a quick resolution of an asylum seeker’s case, and it does not respond efficiently to large numbers in a short time span.

description: In the context of a cosmological study of the bulk flows in the Universe, we present a detailed study of the statistical properties of the kinematic Sunyaev-Zel'dovich (kSZ) effect. We first compute analytically the correlation function and the power spectrum of the projected peculiar velocities of galaxy clusters. By taking into account the spatial clustering properties of these sources, we perform a line-of-sight computation of the {\em all-sky} kSZ power spectrum and find that at large angular scales ($l<10$), the local bulk flow should leave a visible signature above the Poisson-like fluctuations dominant at smaller scales, while the coupling of density and velocity fluctuations should give much smaller contribution. We conduct an analysis of the prospects of future high resolution CMB experiments (such as ACT and SPT) to detect the kSZ signal and to extract cosmological information and dark energy constraints from it. We present two complementary methods, one suitable for ``deep and narrow'' surveys such as ACT and one suitable for ``wide and shallow'' surveys such as SPT. Both methods can constraint the equation of state of dark energy $w$ to about 5-10% when applied to forthcoming and future surveys, and probe $w$ in complementary redshift ranges, which could shed some light on its time evolution. These determinations of $w$ do not rely on the knowledge of cluster masses, although they make minimal assumptions on cluster physics.

Tsallis Ensemble as an Exact Orthode

description: We show that Tsallis ensemble of power-law distributions provides a mechanical model of nonextensive equilibrium thermodynamics for small interacting Hamiltonian systems, i.e., using Boltzmann's original nomenclature, we prove that it is an exact orthode. This means that the heat differential admits the inverse average kinetic energy as an integrating factor. One immediate consequence is that the logarithm of the normalization function can be identified with the entropy, instead of the q-deformed logarithm. It has been noted that such entropy coincides with Renyi entropy rather than Tsallis entropy, it is non-additive, tends to the standard canonical entropy as the power index tends to infinity and is consistent with the free energy formula proposed in [S. Abe et. al. Phys. Lett. A 281, 126 (2001)]. It is also shown that the heat differential admits the Lagrange multiplier used in non-extensive thermodynamics as an integrating factor too, and that the associated entropy is given by ordinary nonextensive entropy. The mechanical approach proposed in this work is fully consistent with an information-theoretic approach based on the maximization of Renyi entropy.

The significant increase in cross sections at backward hemisphere due to the contribution of alphacluster transfer is investigated using the distorted wave Born approximation (DWBA) method. The spectroscopic amplitude (SA) for the configuration 20Ne as consisting of 16O (core) and an alpha-particle orbiting this core at the different concerned energies is extracted. The agreement between the experimental data and theoretical calculations using the two considered approaches is reasonably good.

description: Magnetic tunnel junctions operating in the superparamagnetic regime are promising devices in the field of probabilistic computing, which is suitable for applications like high-dimensional optimization or sampling problems. Further, random number generation is of interest in the field of cryptography. For such applications, a device's uncorrelated fluctuation time-scale can determine the effective system speed. It has been theoretically proposed that a magnetic tunnel junction designed to have only easy-plane anisotropy provides fluctuation rates determined by its easy-plane anisotropy field, and can perform on nanosecond or faster time-scale as measured by its magnetoresistance's autocorrelation in time. Here we provide experimental evidence of nanosecond scale fluctuations in a circular shaped easy-plane magnetic tunnel junction, consistent with finite-temperature coupled macrospin simulation results and prior theoretical expectations. We further assess the degree of stochasticity of such signal.
Streetcar strip to neighbourhood centre: the characteristics of good neighbourhood shopping streets examined in the context of Commercial Drive and West 41st Avenue

description: Good neighbourhood shopping streets have long been significant in their ability to provide goods and services within walking distance of neighbourhood residents, to create a rich public realm, and to foster a sense of community. Far removed from their past as streetcar strips, the neighbourhood shopping street is once again being looked at as an important element of the urban environment. The purpose of this thesis is to determine the characteristics of good neighbourhood shopping streets and to examine these characteristics in the context of two Vancouver case studies—Commercial Drive and West 41st Avenue. Based on a review of planning, urban design, and landscape architecture literature, the fundamental principles of good neighbourhood shopping streets are revealed. Specifically, a good neighbourhood shopping street is accessible, comfortable, sociable, a place, adaptable, beautiful, and diverse. Flowing from these principles, and the means to them, are the characteristics of good neighbourhood shopping streets—buildings that relate to the street, good walking facilities, pedestrian amenities, traffic management, street activity, neighbourhood goods and services, maintenance, supportive neighbourhood context, and supportive government. The research suggests that real-life neighbourhood shopping streets rarely have all the characteristics that the literature holds as ideal. Rather, some characteristics— buildings that relate to the street, street activity, neighbourhood goods and services, a supportive neighbourhood context, and supportive government—appear as fundamental to good neighbourhood shopping streets but are exhibited to varying degrees. More specifically, the case studies help illustrate what particular elements are either essential or helpful, creating a checklist that other streets can benefit from.

description: There is reason to suspect that about half of the baryons are in pressure-supported plasma in the halos of normal galaxies, drawn in by gravity along with about half of the dark matter. To be consistent with the observations this baryonic component, the corona, would have to be hotter than the kinetic temperature of the dark matter in the halo so as to produce acceptable central electron densities. We ascribe this hotter plasma temperature to the addition of entropy prior to and during assembly of the system, in an analogy to cluster formation. The plasma cooling time would be longer than the gravitational collapse time but, in the inner parts, shorter than the Hubble time, making the corona thermally unstable to the formation of a cloudy structure that may be in line with what is indicated by quasar absorption line systems. The corona of an isolated spiral galaxy would be a source of soft X-ray and recombination radiation, adding to the more commonly discussed effects of stars and supernovae. In this picture the mass in the corona is much larger than the mass in condensed baryons in a spiral galaxy. The corona thus would be a substantial reservoir of diffuse baryons that are settling and adding to the mass in interstellar matter and stars, so that star formation in isolated spirals will continue well beyond the present epoch.

Ballistic spin field-effect transistors: Multichannel effects

description: We study a ballistic spin field-effect transistor (SFET) with special attention to the issue of multi-channel effects. The conductance modulation of the SFET as a function of the Rashba spin-orbit coupling strength is numerically examined for the number of channels ranging from a few to close to 100. Even with the ideal spin injector and collector, the conductance modulation ratio, defined as the ratio between the maximum and minimum conductances, decays rapidly and approaches one with the increase of the channel number. It turns out that the decay is considerably faster when the Rashba spin-orbit coupling is larger. Effects of the electronic coherence are also examined in the multi-channel regime and it is found that the coherent Fabry-Perot-like interference in the multi-channel regime gives rise to a nested peak structure. For a nonideal spin injector/collector structure, which consists of a conventional metallic ferromagnet-thin insulator-2DEG heterostructure, the Rashba-coupling-induced conductance modulation is strongly affected by large resonance peaks that arise from the electron confinement effect of the insulators. Finally scattering effects are briefly addressed and it is found that in the weakly diffusive regime, the positions of the resonance peaks fluctuate, making the conductance modulation signal sample-dependent.

description: Correlations and fluctuations (the latter are directly related to the 2-particle correlations) is one of the important directions in analysis of heavy ion collisions. At the current stage of RHIC exploration, when the details matter, basically any physics question is addressed with help of correlation techniques. In this talk I start with a general introduction to the correlation and fluctuation formalism and discuss weak and strong sides of different type of observables. In more detail, I discuss the two-particle $p_t$ correlations/$\mpt$ fluctuations. In spite of not observing any dramatic changes in the event-by-event fluctuations with energy, which would indicate a possible phase transition, such correlations measurements remain an interesting and important subject, bringing valuable information. Lastly, I show how radial flow can generate characteristic azimuthal, transverse momentum and rapidity correlations, which could qualitatively explain many of recently observed phenomena in nuclear collisions.

description: In teacher-student framework, a more experienced agent (teacher) helps accelerate the learning of another agent (student) by suggesting actions to take in certain states. In cooperative multiagent reinforcement learning (MARL), where agents need to cooperate with one another, a student may fail to cooperate well with others even by following the teachers' suggested actions, as the polices of all agents are ever changing before convergence. When the number of times that agents communicate with one another is limited (i.e., there is budget constraint), the advising strategy that uses actions as advices may not be good enough. We propose a partaker-sharer advising framework (PSAF) for cooperative MARL agents learning with budget constraint. In PSAF, each Q-learner can decide when to ask for Q-values and share its Q-values. We perform experiments in three typical multiagent learning problems. Evaluation results show that our approach PSAF outperforms existing advising methods under both unlimited and limited budget, and we give an analysis of the impact of advising actions and sharing Q-values on agents' learning.

description: Let phi be a Dubins-Freedman random homeomorphism on [0,1] derived from the base measure uniform on the vertical line x=1/2, and let f be a periodic function satisfying that |f(x)-f(0)| = o(1/log log log 1/x). Then the Fourier expansion of f composed with phi converges at 0 with probability 1. In the condition on f, o cannot be replaced by O. Also we deduce some 0-1 laws for this kind of problems.

description: We present integral-field spectroscopy of the ionized gas in the central regions of four galaxies with a low surface brightness disk taken with the Visible Multi Object Spectrograph at the Very Large Telescope and aimed at testing the accuracy in the determination of the central logarithmic slope $α$ of the mass density radial profile $ρ(r) \propto r^α$ in this class of objects. For all the sample galaxies we subtracted from the observed velocity field the best-fit model of gas in circular motions and derived the residuals. Only ESO-LV 5340200 is characterized by a regular velocity field. We extracted the velocity curves of this galaxy along several position angles, in order to estimate the uncertainty in deriving the central gradient of the total mass density from long-slit spectroscopy. We report the detection of strong non-ordered motions of the ionized gas in three out of four sample galaxies. The deviations have velocity amplitudes and spatial scales that make not possible to disentangle between cuspy and core density radial profiles.
