description: We study whether the nonmonotonic behavior found in the differential cross section of the phi-meson photoproduction near threshold can be described by a resonance. Namely, we add a resonance to a model consisting of Pomeron and (pi,eta) exchange by fiat and see if, with a suitable assignment of spin and parity, mass and width, as well as the coupling constants, one would be able to obtain a good description to all the data reported by the LEPS collaboration in the low-energy region. The resonant contribution is evaluated by using an effective Lagrangian approach. We find that, with the assumption of a J^P=3/2^- resonance with mass of 2.10 +- 0.03 GeV and width of 0.465 +- 0.141 GeV, LEPS data can indeed be well described. The ratio of the helicity amplitudes A_(1/2)/A_(3/2) calculated from the resulting coupling constants differs in sign from that of the known D13(2080). We further find that the addition of this postulated resonance can substantially improve the agreement between the existing theoretical predictions and the recent omega photoproduction data if a large value of the OZI evading parameter x_OZI = 12 is assumed for the resonance.

description: We propose and analyze a scheme for sympathetic cooling of the translational motion of polar molecules in an optical lattice, interacting one by one with laser-cooled ions in a radio-frequency trap. The energy gap between the excitation spectra of the particles in their respective trapping potentials is bridged by means of a parametric resonance, provided by the additional modulation of the RF field. We analyze two scenarios: simultaneous laser cooling and energy exchange between the ion and the molecule, and a scheme when these two processes take place separately. We calculate the lowest final energy of the molecule and the cooling rate depending on the amplitude of the parametric modulation. For small parametric modulation, the dynamics can be solved analytically within the rotating wave approximation.

description: Photoinduced polarons in solid films of polymer-fullerene blends were studied by photoluminescence (PL), photoinduced absorption (PIA) and electron spin resonance (ESR). The donor materials used were P3HT and MEH-PPV. As acceptors we employed PC60BM as reference and various soluble C70-derivates: PC70BM, two different diphenylmethano-[70]fullerene oligoether (C70-DPM-OE) and two dimers, C70-C70 and C60-C70. Blend films containing C70 revealed characteristic spectroscopic signatures not seen with C60. Light-induced ESR showed signals at g\geq2.005, assigned to an electron localized on the C70 cage. The formation of C70 radical anions also leads to a subgap PIA band at 0.92 eV, hidden in the spectra of C70-based P3HT and MEH-PPV blends, which allows for more exact studies of charge separated states in conjugated polymer:C70 blends.

description: Standard singularity theorems are proven in Lorentzian manifolds of arbitrary dimension n if they contain closed trapped submanifolds of arbitrary co-dimension. By using the mean curvature vector to characterize trapped submanifolds, a unification of the several possibilities for the boundary conditions in the traditional theorems and their generalization to arbitrary co-dimension is achieved. The classical convergence conditions must be replaced by a condition on sectional curvatures, or tidal forces, which reduces to the former in the cases of co-dimension 1, 2 or n.

"Hey, where can I go for help?" : Aboriginal people and "good medicine" at an urban Aboriginal health agency
Creators: name: Wilson, Margaret
Publisher: name: University of British Columbia
Year: 2018

description: This dissertation examines the perspectives and experiences of urban Aboriginal people who utilize cultural, social and health services and staff who work at an urban Aboriginal agency located in Surrey, British Columbia (BC). Availability, accessibility, and acceptability of health services from the perspectives of urban Aboriginal people are emphasized to inform future policy and services offered to urban Aboriginal people by the BC provincial health care system. Archibald’s (2008) seven Indigenous Storywork principles of respect, responsibility, reciprocity, reverence, holism, inter-relatedness, and synergy form the foundation of the Indigenous methodology for this study. Kirkness and Barnhardt’s (1991) principle of relevance is added to the methodology. The traditional story and metaphor of Hamumu, (Butterfly) from my family in Kwakiutl territory, Kalugwis/Turnour Island also guides methodological and theoretical aspects of this thesis. Hamumu highlights transformation and the metamorphosis of urban Aboriginal people’s lives, including mine, through wholistic health services that address physical, emotional, mental, and spiritual well-being. The development of a Hamumu Theoretical Framework for this research is an outcome of a critical examination of colonial impacts upon urban Aboriginal people and the start of a self-determining conceptual health framework based on local Indigenous knowledge. Three sources of knowledge which shape the development of an Indigenous Good Medicine Theory include: (1) my personal story; (2) perspectives and health-related stories of 14 urban Aboriginal people; and (3) health and policy literature. The Indigenous Good Medicine Theory includes approaches that focus on culture, comfort, collaboration, and communication.
Consequences from conservation of the total density of the universe during the expansion

Subjects: subject: General Physics (physics.gen-ph)

description: The recent Cosmic Microwave Background (CMB) experiments have shown that the average density of the universe is close to the critical one and the universe is asymptotically flat (Euclidean). Taking into account that the universe remains flat and the total density of the universe $Ω_{0}$ is conserved equal to a unit during the cosmological expansion, the Schwarzschild radius of the observable universe has been determined equal to the Hubble distance $R_{s}=2GM/c^{2}=R\sim c/H$, where M is the mass of the observable universe, R is the Hubble distance and H is the Hubble constant. Besides, it has been shown that the speed of the light c appears the parabolic velocity for the observable universe $c=\sqrt{2GM/R}=v_{p}$ and the recessional velocity $v_{r}=Hr$ of an arbitrary galaxy at a distance r > 100 Mps from the observer, is equal to the parabolic velocity for the sphere, having radius r and a centre, coinciding with the observer. The requirement for conservation of $Ω_{0}=1$ during the expansion enables to derive the Hoyle-Carvalho formula for the mass of the observable universe $M=c^{3}/(2GH)$ by a new approach. Key words: flat universe; critical density of the universe; Schwarzschild radius; mass of the universe; parabolic velocity

description: We investigate the dynamical Casimir effect and its detection with Rydberg atoms. The photons are created in a resonant cavity with a plasma mirror of a semiconductor slab which is irradiated by periodic laser pulses. The canonical Hamiltonian is derived for the creation and annihilation operators showing the explicit time-variation in the couplings, which originates from the external configuration such as a nonstationary plasma mirror. The number of created photons is evaluated as squeezing from the Heisenberg equations with the Hamiltonian. Then, the detection of the photons as the atomic excitations is examined through the atom-field interaction. Some consideration is made for a feasible experimental realization with a semiconductor plasma mirror.

description: We study the phases and phase transition lines of the finite temperature G(2) Higgs model. Our work is based on an efficient local hybrid Monte-Carlo algorithm which allows for accurate measurements of expectation values, histograms and susceptibilities. On smaller lattices we calculate the phase diagram in terms of the inverse gauge coupling $β$ and the hopping parameter $κ$. For $κ\to 0$ the model reduces to G(2) gluodynamics and for $κ\to\infty$ to SU(3) gluodynamics. In both limits the system shows a first order confinement-deconfinement transition. We show that the first order transitions at asymptotic values of the hopping parameter are almost joined by a line of first order transitions. A careful analysis reveals that there exists a small gap in the line where the first order transitions turn into continuous transitions or a cross-over region. For $β\to\infty$ the gauge degrees of freedom are frozen and one finds a nonlinear O(7) sigma model which exhibits a second order transition from a massive O(7)-symmetric to a massless O(6)-symmetric phase. The corresponding second order line for large $β$ remains second order for intermediate $β$ until it comes close to the gap between the two first order lines. Besides this second order line and the first order confinement-deconfinement transitions we find a line of monopole-driven bulk transitions which do not interfer with the confinement-deconfinment transitions.

The vortex is pinned when the impurity is close to the vortex core. The bound states shows up for the unpinned vortex and are wiped out by a impurity. Our results are in good agreement with recent experiments and present a consistent explanation for the different electronic structure of vortex core revealed by experiments on different materials.

description: Time series data, such as weather forecasts, stock market trends, or heart rate monitors, plays a vital role in many areas of our lives. However, creating realistic synthetic time series data for research and testing purposes has been a significant challenge due to limitations in existing methods, which often struggle with accuracy and consistency. In this study, we developed two new approaches to generate high-quality time series data more effectively. The first method introduces a dual-feedback system that helps the model learn and replicate real data patterns more accurately by providing guidance at different stages of the learning process. The second method features a novel design that works well with both short and long sequences of data, making it versatile for various applications. Both methods incorporate innovative techniques to improve stability and ensure the generated data closely mirrors real-world patterns. These techniques include algorithms for preserving the best model during training, novel cost functions, and an integrated joint training mechanism to enhance performance. We tested these approaches on different types of time series data, including financial markets and medical signals. The results showed that our methods consistently produced more accurate and reliable data than existing standard techniques.
Buoyancy-induced time delays in Babcock-Leighton flux-transport dynamo models

description: The Sun is a magnetic star whose cyclic activity is thought to be linked to internal dynamo mechanisms. A combination of numerical modelling with various levels of complexity is an efficient and accurate tool to investigate such intricate dynamical processes. We investigate the role of the magnetic buoyancy process in 2D Babcock-Leighton dynamo models, by modelling more accurately the surface source term for poloidal field. Methods. To do so, we reintroduce in mean-field models the results of full 3D MHD calculations of the non-linear evolution of a rising flux tube in a convective shell. More specifically, the Babcock-Leighton source term is modified to take into account the delay introduced by the rise time of the toroidal structures from the base of the convection zone to the solar surface. We find that the time delays introduced in the equations produce large temporal modulation of the cycle amplitude even when strong and thus rapidly rising flux tubes are considered. Aperiodic modulations of the solar cycle appear after a sequence of period doubling bifurcations typical of non-linear systems. The strong effects introduced even by small delays is found to be due to the dependence of the delays on the magnetic field strength at the base of the convection zone, the modulation being much less when time delays remain constant. We do not find any significant influence on the cycle period except when the delays are made artificially strong. A possible new origin of the solar cycle variability is here revealed. This modulated activity and the resulting butterfly diagram are then more compatible with observations than what the standard Babcock-Leighton model produces.

description: We report the discovery of the first new ultra-cool brown dwarf found with the Wide-field Infrared Survey Explorer (WISE). The object's preliminary designation is WISEPC J045853.90+643451.9. Follow-up spectroscopy with the LUCIFER instrument on the Large Binocular Telescope indicates that it is a very late-type T dwarf with a spectral type approximately equal to T9. Fits to an IRTF/SpeX 0.8-2.5 micron spectrum to the model atmospheres of Marley and Saumon indicate an effective temperature of approximately 600 K as well as the presence of vertical mixing in its atmosphere. The new brown dwarf is easily detected by WISE, with a signal-to-noise ratio of ~36 at 4.6 microns. Current estimates place it at a distance of 6 to 10 pc. This object represents the first in what will likely be hundreds of nearby brown dwarfs found by WISE that will be suitable for follow up observations, including those with the James Webb Space Telescope. One of the two primary scientific goals of the WISE mission is to find the coolest, closest stars to our Sun; the discovery of this new brown dwarf proves that WISE is capable of fulfilling this objective.

Feedback Message Passing for Inference in Gaussian Graphical Models

description: While loopy belief propagation (LBP) performs reasonably well for inference in some Gaussian graphical models with cycles, its performance is unsatisfactory for many others. In particular for some models LBP does not converge, and in general when it does converge, the computed variances are incorrect (except for cycle-free graphs for which belief propagation (BP) is non-iterative and exact). In this paper we propose {\em feedback message passing} (FMP), a message-passing algorithm that makes use of a special set of vertices (called a {\em feedback vertex set} or {\em FVS}) whose removal results in a cycle-free graph. In FMP, standard BP is employed several times on the cycle-free subgraph excluding the FVS while a special message-passing scheme is used for the nodes in the FVS. The computational complexity of exact inference is $O(k^2n)$, where $k$ is the number of feedback nodes, and $n$ is the total number of nodes. When the size of the FVS is very large, FMP is intractable. Hence we propose {\em approximate FMP}, where a pseudo-FVS is used instead of an FVS, and where inference in the non-cycle-free graph obtained by removing the pseudo-FVS is carried out approximately using LBP. We show that, when approximate FMP converges, it yields exact means and variances on the pseudo-FVS and exact means throughout the remainder of the graph. We also provide theoretical results on the convergence and accuracy of approximate FMP. In particular, we prove error bounds on variance computation. Based on these theoretical results, we design efficient algorithms to select a pseudo-FVS of bounded size. The choice of the pseudo-FVS allows us to explicitly trade off between efficiency and accuracy. Experimental results show that using a pseudo-FVS of size no larger than $\log(n)$, this procedure converges much more often, more quickly, and provides more accurate results than LBP on the entire graph.

description: We study a planar metamaterial supporting electromagnetically-induced transparency (EIT)-like effect by exploiting the coupling between bright and quasi-dark eigenmodes. The specific design of such a metamaterial consists of a cut-wire (CW) and a single-gap split-ring resonator (SRR). From the numerical and the analytical results we demonstrate that the response of SRR, which is weakly excited by external electric field, is mitigated to be a quasi-dark eigenmode in the presence of strongly radiative CW. This result suggests more relaxed conditions for the realization of devices utilizing the EIT-like effects in metamaterial, and thereby widens the possibilities for many different structural implementations.

Linguistic dating of biblical texts : proponents, challengers and Judges 5
Creators: name: Felushko, Brian G.
Publisher: name: University of British Columbia
Year: 2018

description: Whether the biblical texts can or cannot be dated has a significant impact on the reliability, or usefulness in using them to reconstruct Israelite history. In addition, knowing when a text was written impacts our ability to understand what its meaning was for its readers. Some biblical texts can be dated to the post-exilic period with relative confidence based on convergences between content and historically dated extra-biblical material and/or literary sources. This corpus, for most scholars, would include Esther, Daniel, Ezra, Nehemiah and Chronicles. Beyond these, however, there is much debate about whether it is possible to even provide relative dates to any other texts. Numerous scholars, past and present, confidently assert that linguistic features can date biblical texts, on the basis of typology, to at least one of three periods: pre-monarchic, pre-exilic or post-exilic. In contrast, especially since the early 1990s, numerous linguists, Hebraists, and Hebrew Bible scholars have challenged that thesis. In large part, they reject the idea that typology indicates chronology and argue rather that it is indicative of authorial/editorial style and of genre. The purpose of this paper is, first, to summarize and explain each side in this debate. This will be followed by a linguistic analysis of Judges 5 in order to demonstrate the principle that linguistic features alone are insufficient for textual dating. This conclusion will be supported through a critique of some of the essential assumptions on each side of the debate. Finally, I will offer a path through the current impasse and towards continued study and respectful discussion that will add to our knowledge and deepen our understanding of the role of linguistic features in the dating of biblical texts.

description: Based on quantum mechanical approach the polarization transport of photons which propagate in a medium with slow varying refractive index is studied. The photon polarizations are separated in opposite directions normal to the ray which is called "Spin Hall effect" of photons, and also the rotation of polarization plane, a manifestation of the Berry phase, occurs. This approach can be generalized to other spinning particles in inhomogeneous media as a universal approach.

What can be learned from binding energy differences about nuclear structure: the example of delta V_{pn}

description: We perform an analysis of a binding energy difference called delta V_{pn}(N,Z) =- 1/4(E(Z,N)-E(Z,N-2)-E(Z-2,N)+ E(Z-2,N-2) in the framework of a realistic nuclear model. Using the angular-momentum and particle-number projected generator coordinate method and the Skyrme interaction SLy4, we analyze the contribution brought to delta V_{pn} by static deformation and dynamic fluctuations around the mean-field ground state. Our method gives a good overall description of delta V_{pn} throughout the chart of nuclei with the exception of the anomaly related to the Wigner energy along the N=Z line. The main conclusions of our analysis are that (i) the structures seen in the systematics of delta V_{pn} throughout the chart of nuclei can be easily explained combining a smooth background related to the symmetry energy and correlation energies due to deformation and collective fluctuations; (ii) the characteristic pattern of delta V_{pn} around a doubly-magic nucleus is a trivial consequence of the asymmetric definition of delta V_{pn}, and not due to a the different structure of these nuclei; (iii) delta V_{pn} does not provide a very reliable indicator for structural changes; (iv) δV_{pn} does not provide a reliable measure of the proton-neutron interaction in the nuclear EDF, neither of that between the last filled orbits, nor of the one summed over all orbits; (v) delta V_{pn} does not provide a conclusive benchmark for nuclear EDF methods that is superior or complementary to other mass filters such as two-nucleon separation energies or Q values.

description: The Approach unifying spin and charges, assuming that all the internal degrees of freedom---the spin, all the charges and the families---originate in $d > (1+3)$ in only two kinds of spins (the Dirac one and the only one existing beside the Dirac one and anticommuting with the Dirac one), is offering a new way in understanding the appearance of the families and the charges (in the case of charges the similarity with the Kaluza-Klein-like theories must be emphasized). A simple starting action in $d >(1+3)$ for gauge fields (the vielbeins and the two kinds of the spin connections) and a spinor (which carries only two kinds of spins and interacts with the corresponding gauge fields) manifests after particular breaks of the starting symmetry the massless four (rather than three) families with the properties as assumed by the Standard model for the three known families, and the additional four massive families. The lowest of these additional four families is stable. A part of the starting action contributes, together with the vielbeins, in the break of the electroweak symmetry manifesting in $d=(1+3)$ the Yukawa couplings (determining the mixing matrices and the masses of the lower four families of fermions and influencing the properties of the higher four families) and the scalar field, which determines the masses of the gauge fields. The fourth family might be seen at the LHC, while the stable fifth family might be what is observed as the dark matter.

Damage, collapse potential and long duration effects of subduction ground motions on structural systems
Creators: name: Capraro, Ilaria
Publisher: name: University of British Columbia
Year: 2018

description: Current code designs are based on design spectrum which does not account adequately for long duration shaking and therefore they do not reflect the duration effects of subduction earthquakes on seismic demands. The 2015 edition of the National Building Code of Canada (NBCC) probabilistically includes the effects of subduction earthquakes in developing the Uniform Hazard Spectrum (UHS), thus leading to increased interest in the impact of subduction ground motions on seismic demands for design. The research aim of this thesis is to investigate in detail the impact of subduction motions on design, particularly the effect of duration and the evaluation of the damage potential of the subduction motions. The evidence of structural damage observed during reconnaissance after the 2011 Tohoku and 2010 Maule subduction earthquakes was used to investigate the characteristics of ground motions that could be used as consistent indicators of damage potential. Characteristics considered were basic shaking parameters, as well as spectral parameters. Among the parameters considered, the constant strength spectrum appeared to be the best indicator. The effects of the long duration shaking due to subduction motions on the dynamic performance of structures was investigated using Incremental Nonlinear Dynamic Analysis (IDA). The response of several nonlinear Single-Degree-of-Freedom (SDOF) systems designed using a force-reduction factor of 5.0, covering a wide range of fundamental periods and ductility capacities was studied. The effect of duration was isolated by compiling two suites of spectrally compatible motions representing crustal and subduction earthquakes. Based on the drift ratios from IDAs, fragility curves were developed giving the probability of exceeding a prescribed drift ratio. The study clearly showed that the conditional probability of exceeding a prescribed drift for subduction earthquakes is higher than the probability associated with crustal motions. However, the magnitude of this effect depends on the fundamental period, the ductility of the building and the shaking intensity. In order to investigate how the above findings apply to a Multi-Degree-of-Freedom (MDOF) building, the same pair of input motions were used to run IDA on a 6-storey reinforced concrete (RC) moment frame. The resulting fragility curves confirmed the findings obtained with the SDOF analyses.

description: Direct photon spectra are calculated within a transport+hydrodynamics hybrid approach, in which the high-density part of the transport evolution has been replaced by a 3+1-dimensional hydrodynamic calculation. We study the effects of changing the parameters of the two interfaces between the transport- and hydrodynamic descriptions on the resulting direct photon spectra.

description: The synthetic control (SC) method, a powerful tool for estimating average treatment effects (ATE), is increasingly popular in fields such as statistics, economics, political science, and marketing. The SC is particularly suitable for estimating ATE with a single (or a few) treated unit(s), a fixed number of control units, and large pre and post-treatment periods (which we refer as “long panels”). To date, there has been no formal inference theory for SC ATE estimator with long panels under general conditions. Existing work mostly use placebo tests for inference or some permutation methods when the post-treatment period is small. In this article, we derive the asymptotic distribution of the SC and modified synthetic control (MSC) ATE estimators using projection theory. We show that a properly designed subsampling method can be used to obtain confidence intervals and conduct inference whereas the standard bootstrap cannot. Simulations and an empirical application that examines the effect of opening a physical showroom by an e-tailer demonstrate the usefulness of the MSC method in applications.

description: We consider the possibility that solid molecular hydrogen is present in interstellar space. If so cosmic-rays and energetic photons cause ionisation in the solid leading to the formation of H6+. This ion is not produced by gas-phase reactions and its radiative transitions therefore provide a signature of solid H2 in the astrophysical context. The vibrational transitions of H6+ are yet to be observed in the laboratory, but we have characterised them in a quantum-theoretical treatment of the molecule; our calculations include anharmonic corrections, which are large. Here we report on those calculations and compare our results with astronomical data. In addition to the H6+ isotopomer, we focus on the deuterated species (HD)3+ which is expected to dominate at low ionisation rates as a result of isotopic condensation reactions. We can reliably predict the frequencies of the fundamental bands for five modes of vibration. For (HD)3+ all of these are found to lie close to some of the strongest of the pervasive mid-infrared astronomical emission bands, making it difficult to exclude hydrogen precipitates on observational grounds. By the same token these results suggest that (HD)3+ could be the carrier of the observed bands. We consider this possibility within the broader picture of ISM photo-processes and we conclude that solid hydrogen may indeed be abundant in astrophysical environments.

description: The positive relationship between airborne fine particulate matter (PM2.5) and cardiovascular disease (CVD) is established. Little is known about effect size heterogeneity across distinct CVD outcomes. We conducted a multi-outcome case-crossover study of Medicare beneficiaries aged > 65 years residing in the mainland USA from 2000 through 2012. The exposure was two-day average PM2.5 in each individual’s residential zipcode. The outcomes were hospitalization for 432 distinct CVDs defined by the International Classification of Diseases, Revision 9. Our dataset included almost 24 million CVD hospitalizations. We analyzed the data using Multi-Outcome Regression with Tree-structured Shrinkage (MOReTreeS), a novel method that enables: (1) borrowing of strength across outcomes; (2) data-driven discovery of outcome groups that are similarly affected by the exposure; (3) estimation of a single effect for each group. MOReTreeS grouped 420 outcomes together; for this group, the odds ratio [OR] for hospitalization associated with a 10μg·m– 3 increase in PM2.5 was 1.011 (95% credible interval [CI] = 1.011 to 1.012). The model identified congestive heart failure as having the strongest positive association with PM2.5 (OR = 1.019; 95%CI = 1.017 to 1.022). Some outcomes exhibited negative associations with PM2.5, including aortic dissection, subarachnoid and intracerebral hemorrhage, abdominal aneurysm, and essential hypertension; further research is needed to understand these counterintuitive findings.

In engaging technologies and the built environment within the social sci- ences, there increasingly have been appeals to examine the intricacies of time and temporalities in our collective interactions with science and technology more thoroughly. This seems particularly relevant when we consider the rhythms, cycles, rituals, (a)synchronicities, and time horizons of infrastruc- tural configurations. Studying repair and maintenance practices reveals how temporal properties of infrastructure are not only conceptually relevant in understanding socio-material relations, but also of very practical concern to members of society engaging in such relations.

description: We introduce a new shrinkage prior on function spaces, called the functional horseshoe (fHS) prior, that encourages shrinkage toward parametric classes of functions. Unlike other shrinkage priors for parametric models, the fHS shrinkage acts on the shape of the function rather than inducing sparsity on model parameters. We study the efficacy of the proposed approach by showing an adaptive posterior concentration property on the function. We also demonstrate consistency of the model selection procedure that thresholds the shrinkage parameter of the fHS prior. We apply the fHS prior to nonparametric additive models and compare its performance with procedures based on the standard horseshoe prior and several penalized likelihood approaches. We find that the new procedure achieves smaller estimation error and more accurate model selection than other procedures in several simulated and real examples. Supplementary materials for this article, which contain additional simulated and real data examples, MCMC diagnostics, and proofs of the theoretical results, are available online.

description: Kidney obstruction, if untreated in a timely manner, can lead to irreversible loss of renal function. A widely used technology for evaluations of kidneys with suspected obstruction is diuresis renography. However, it is generally very challenging for radiologists who typically interpret renography data in practice to build high level of competency due to the low volume of renography studies and insufficient training. Another challenge is that there is currently no gold standard for detection of kidney obstruction. Seeking to develop a computer-aided diagnostic (CAD) tool that can assist practicing radiologists to reduce errors in the interpretation of kidney obstruction, a recent study collected data from diuresis renography, interpretations on the renography data from highly experienced nuclear medicine experts as well as clinical data. To achieve the objective, we develop a statistical model that can be used as a CAD tool for assisting radiologists in kidney interpretation. We use a Bayesian latent class modeling approach for predicting kidney obstruction through the integrative analysis of time-series renogram data, expert ratings, and clinical variables. A nonparametric Bayesian latent factor regression approach is adopted for modeling renogram curves in which the coefficients of the basis functions are parameterized via the factor loadings dependent on the latent disease status and the extended latent factors that can also adjust for clinical variables. A hierarchical probit model is used for expert ratings, allowing for training with rating data from multiple experts while predicting with at most one expert, which makes the proposed model operable in practice. An efficient MCMC algorithm is developed to train the model and predict kidney obstruction with associated uncertainty. We demonstrate the superiority of the proposed method over several existing methods through extensive simulations. Analysis of the renal study also lends support to the usefulness of our model as a CAD tool to assist less experienced radiologists in the field.
Partner trust and childhood emotional maltreatment : considering the roles of maladaptive schemas and psychological flexibility
Creators: name: Baugh, Leah M.
Publisher: name: University of British Columbia

description: Victims of childhood emotional maltreatment (CEM) often experience lasting interpersonal impacts. CEM is commonly experienced as a betrayal of trust and can lead victims to generalize this mistrust to relationships in adulthood, including their romantic partners. The aim of the present study was to better understand the association between CEM and partner trust by examining the relative strength of three potential mediators – psychological flexibility, maladaptive self schemas, and maladaptive other schemas. The study also investigated whether psychological flexibility buffers the association between maladaptive schemas and partner trust. Adults (N = 231) in committed romantic relationships completed measures of CEM, romantic partner trust, maladaptive schemas, and psychological flexibility. Simple and multiple mediation analyses were performed. I found that maladaptive self schemas were a stronger mediator than maladaptive other schemas; however, psychological flexibility was a more potent mediator than either schema type. Contrary to my hypothesis, psychological flexibility did not significantly moderate the effect of maladaptive schemas on partner trust. The findings highlight the importance of attending to and increasing psychological flexibility with victims of CEM to facilitate romantic partner trust. Practical and clinical implications are discussed.

description: We investigate the thermodynamics of a combined Dicke- and Ising-model which exhibits a rich phenomenology arising from the second order and quantum phase transitions from the respective models. The partition function is calculated using mean field theory, and the free energy is analyzed in detail to determine the complete phase diagram for the system. The analysis reveals both first- and second-order Dicke phase transitions into a super-radiant state, and the cavity mean-field in this regime acts as an effective magnetic field, which restricts the Ising chain dynamics to parameter ranges away from the Ising phase transition. Physical systems with a first order phase transitions are natural candidates for metrology and calibration purposes, and we apply filter theory to show that the sensitivity of the physical system to temperature and external fields reaches the 1/N Heisenberg limit.
