Multiply sectioned Bayesian belief networks for large knowledge-based systems: an application to neuromuscular diagnosis
Creators: name: Xiang, Yang
Publisher: name: University of British Columbia
Year: 2008

description: In medical diagnosis a proper uncertainty calculus is crucial in knowledge representation. Finite calculus is close to human language and should facilitate knowledge acquisition. An investigation into the feasibility of finite totally ordered probability models has been conducted. It shows that a finite model is of limited usage, which highlights the importance of infinite totally ordered models including probability theory. Representing the qualitative domain structure is another important issue. Bayesian networks, combining graphical representation of domain dependency and probability theory, provide a concise representation and a consistent inference formalism. An expert system QUALICON for quality control in electromyography has been implemented as a pilot study of Bayesian nets. The performance is comparable to that from human professionals. Extending the research into a large system PAINULIM in neuromuscular diagnosis shows that the computation using homogeneous net representation is unnecessarily complex. At any one time a user’s attention is directed to only part of a large net, i.e., there is ‘localization’ of queries and evidence. The homogeneous net is inefficient since the overall net has to be updated each time. Multiply Sectioned Bayesian Networks (MSBNs) have been developed to exploit localization. Reasonable constraints are derived such that a localization preserving partition of a domain and its representation by a set of subnets are possible. Reasoning takes place at only one of them due to localization. Marginal probabilities obtained are identical to those obtained when the entire net is globally consistent. When the user’s attention shifts, a new subnet is swapped in and previously acquired evidence absorbed. Thus, with β subnets, the complexity is reduced approximately to 1/β. Reducing the complexity with MSBN, the knowledge acquisition of PAINULIM has been conducted using normal hospital computers. This results in efficient cooperation with medical staff. PAINULIM was thus constructed in less than one year. An evaluation shows very good performance. Coding probability distribution of Bayesian nets in causal direction has several ad vantages. Initially the distribution is elicited from the expert in terms of probabilities of a symptom given causing diseases. Since disease-to-symptom is not the direction of daily practice, the elicited probabilities may be inaccurate. An algorithm has been derived for sequentially updating probabilities in Bayesian nets, making use of the expert’s symptom to-disease probabilities. Simulation shows better performance than Spiegeihalter’s {O, l} distribution learning.
Deep HDR Hallucination for Inverse Tone Mapping

description: Inverse Tone Mapping (ITM) methods attempt to reconstruct High Dynamic Range (HDR) information from Low Dynamic Range (LDR) image content. The dynamic range of well-exposed areas must be expanded and any missing information due to over/under-exposure must be recovered (hallucinated). The majority of methods focus on the former and are relatively successful, while most attempts on the latter are not of sufficient quality, even ones based on Convolutional Neural Networks (CNNs). A major factor for the reduced inpainting quality in some works is the choice of loss function. Work based on Generative Adversarial Networks (GANs) shows promising results for image synthesis and LDR inpainting, suggesting that GAN losses can improve inverse tone mapping results. This work presents a GAN-based method that hallucinates missing information from badly exposed areas in LDR images and compares its efficacy with alternative variations. The proposed method is quantitatively competitive with state-of-the-art inverse tone mapping methods, providing good dynamic range expansion for well-exposed areas and plausible hallucinations for saturated and under-exposed areas. A density-based normalisation method, targeted for HDR content, is also proposed, as well as an HDR data augmentation method targeted for HDR hallucination.
On scaling laws at the phase transition of systems with divergent order parameter and/or internal length : the example of DNA denaturation

description: We used the Transfer-Integral method to compute, with an uncertainty smaller than 5%, the six fundamental characteristic exponents of two dynamical models for DNA thermal denaturation and investigate the validity of the scaling laws. Doubts concerning this point arise because the investigated systems (i) have a divergent internal length, (ii) are described by a divergent order parameter, (iii) are of dimension 1. We found that the assumption that the free energy can be described by a single homogeneous function is robust, despite the divergence of the order parameter, so that Rushbrooke's and Widom's identities are valid relations. Josephson's identity is instead not satisfied. This is probably due to the divergence of the internal length, which invalidates the assumption that the correlation length is solely responsible for singular contributions to thermodynamic quantities. Fisher's identity is even wronger. We showed that this is due to the d=1 dimensionality and obtained an alternative law, which is well satisfied at DNA thermal denaturation.

description: Using the general expressions for level shifts obtained from the master equation for a small system interacting with a large one considered as a reservoir, we calculate the dispersive potentials between an atom and a wall in the dipole approximation. We analyze in detail the particular case of a two-level atom in the presence of a perfectly conducting wall. We study the van der Waals as well as the resonant interactions. All distance regimes as well as the high and low temperature regimes are considered. We show that the Casimir-Polder interaction can not be considered as a direct result of the vacuum fluctuations only. Concerning the interaction between the atom and the wall at high temperature, which show that a saturation of the potential for all distances occurs. This saturated potential coincides exactly with that obtained in the London-van der Waals limit.

description: The possibility of velocity shear-induced linear transformations of different magnetohydrodynamic waves in the solar wind is studied both analytically and numerically. A quantitative analysis of the wave transformation processes for all possible plasma-$β$ regimes is performed. By applying the obtained criteria for effective wave coupling to the solar wind parameters, we show that velocity shear-induced linear transformations of Alfvén waves into magneto-acoustic waves could effectively take place for the relatively low-frequency Alfvén waves in the energy containing interval. The obtained results are in a good qualitative agreement with the observed features of density perturbations in the solar wind.

We report an experimental implementation of a conditional logical gate between two logical qubits that are each in decoherence free subspaces that protect the quantum information from fully correlated dephasing.

Implicit Bias Against Artificial Intelligence Algorithms

Subjects: subject: Social and Behavioral Sciences
subject: Other Social and Behavioral Sciences

description: We suggest that people develop an implicit bias (i.e., prejudice) against artificial intelligence (AI) systems, as a different and threatening “species” the behavior of which is unknown. We expected people to be guided by this implicit bias but try to override it. This leads to some willingness to rely on algorithmic advice (appreciation) which is reduced as a function of people’s implicit prejudice against the machine. Next, we provide an explanation as to why aversion is ephemeral. As people learn about the performance of an algorithm, they depend less on primal implicit biases when deciding whether to rely on the AI’s advice. Two studies (n1=675, n2=317) that use the Implicit Association Test consistently support this view. Two additional studies (n3=255, n4=332) rule out alternative explanations and provide stronger support for our assertions.
Mass Uncertainties of f0(600) and f0(1370) and their Effects on Determination of the Quark and Glueball Admixtures of the I=0 Scalar Mesons

description: Within a nonlinear chiral Lagrangian framework the correlations between the quark and glueball admixtures of the isosinglet scalar mesons below 2 GeV and the current large uncertainties on the mass of the f0(600) and the f0(1370) are studied. The framework is formulated in terms of two scalar meson nonets (a two-quark nonet and a four-quark nonet) together with a scalar glueball. It is shown that while some properties of these states are sensitive to the mass of f0(600) and f0(1370), several relatively robust conclusions can be made: The f0(600), the f0(980), and the f0(1370) are admixtures of two and four quark components, with f0(600) being dominantly a non-strange four-quark state, and f0(980) and f0(1370) having a dominant two-quark component. Similarly, the f0(1500) and the f0(1710) have considerable two and four quark admixtures, but in addition have a large glueball component. For each state, a detailed analysis providing the numerical estimates of all components is given. It is also shown that this framework clearly favors the experimental values: m[f0(600)] < 700 MeV and m[f0(1370)] = 1300-1450 MeV. Moreover, an overall fit to the available data shows a reciprocal substructure for the f0(600) and the f0(1370), and a linear correlation between their masses of the form m [f0(1370)] = 0.29 m[f0(600)] + 1.22 GeV. The scalar glueball mass of 1.5-1.7 GeV is found in this analysis.

description: A novel method for extracting multipole amplitudes in the nucleon resonance region from electroproduction data is presented. The method is based on statistical concepts and it relies heavily on Monte Carlo and simulation techniques; it produces precise identification and determination of the contributing multipole amplitudes in the resonance region and for the first time a rigorous determination of the associated experimental uncertainty. The results are demonstrated to be independent of any model bias. The method is applied in the reanalysis of the $Q^{2}=0.127 GeV^2/c^2$ Bates and Mainz $N\to Δ$ data.

description: We investigate the behavior of extended urban traffic networks within the framework of percolation theory by using real and synthetic traffic data. Our main focus shifts from the statistical properties of the cluster size distribution studied recently, to the spatial analysis of the clusters at criticality and to the definition of a similarity measure between whole urban configurations. We discover that the breakup patterns of the complete network, formed by the connected functional road clusters at criticality, show remarkable stability from one hour to the next, and predictability for different days at the same time. We prove this by showing how the average spatial distributions of the highest-rank clusters evolve over time, and by building a taxonomy of traffic states via dimensionality-reduction of the distance matrix, obtained via a clustering similarity score. Finally, we show that a simple random percolation model can approximate the breakup patterns of heavy real traffic when long-ranged spatial correlations are imposed.

Vaccum solutions of five-dimensional Einstein equations generated by inverse scattering method II : Production of black ring solution

description: We study vacuum solutions of five-dimensional Einstein equations generated by the inverse scattering method. We reproduce the black ring solution which was found by Emparan and Reall by taking the Euclidean Levi-Civita metric plus one-dimensional flat space as a seed. This transformation consists of two successive processes; the first step is to perform the three-solitonic transformation of the Euclidean Levi-Civita metric with one-dimensional flat space as a seed. The resulting metric is the Euclidean C-metric with extra one-dimensional flat space. The second is to perform the two-solitonic transformation by taking it as a new seed. Our result may serve as a stepping stone to find new exact solutions in higher dimensions.

Harm reduction of switching from metformin plus sulfonylureas to metformin plus DPP4s in older adults: A target trial emulation using German routine claims data
Creators: name: Starke, Paula
Publisher: name: OSF Registries
Year: 2023
Subjects: subject: Medicine and Health Sciences

description: This project is my master thesis. The modalities and form of publication are not determined yet.
I will conduct a study to evaluate the real-world benefit of switching elderly patients from potentially inappropriate medications (PIMs) to alternative medications using an example from diabetic treatment. More concretely, we apply the concept of target trial emulation to analyse the hypothetical intervention of prescribing only DPP4 inhibitors instead of Sulfonyurea in addition to metformin to all patients over 65 years. The hypothesis is that the intervention could reduce adverse events. In addition, we aim to identify heterogenous treatment effects regarding these PIMs. Thus, we aim to identify subgroups within the population of elderly patients that have an especially high risk for adverse events when taking the selected sulfonylurea. The study will use routine claims data from a German health insurance provider.

It corresponds to the transition from glueballs to non-perturbative gluons which condense at a non vanishing momentum. In this respect the proposed phase is analogous to the color superconducting LOFF phase for fermionic systems.

description: Given the long subclinical stage of Alzheimer's disease (AD), the study of biomarkers is relevant both for early diagnosis and the fundamental understanding of the pathophysiology of AD. Biomarkers provided by amyloid-${\unicode[Times]{x3B2}}$ (A${\unicode[Times]{x3B2}}$) plaques have led to an increasing interest in characterizing this hallmark of AD due to its promising potential. In this work, we characterize A${\unicode[Times]{x3B2}}$ plaques by label-free multimodal imaging: we combine two-photon excitation autofluorescence (TPEA), second harmonic generation (SHG), spontaneous Raman scattering (SpRS), coherent anti-Stokes Raman scattering (CARS), and stimulated Raman scattering (SRS) to describe and compare high-resolution images of A${\unicode[Times]{x3B2}}$ plaques in brain tissues of an AD mouse model. Comparing single-laser techniques images, we discuss the origin of the SHG, which can be used to locate the plaque core reliably. We study both the core and the halo with vibrational microscopy and compare SpRS and SRS microscopies for different frequencies. We also combine SpRS spectroscopy with SRS microscopy and present two core biomarkers unexplored with SRS microscopy: phenylalanine and amide B. We provide high-resolution SRS images with the spatial distribution of these biomarkers in the plaque and compared them with images of the amide I distribution. The obtained spatial correlation corroborates the feasibility of these biomarkers in the study of A${\unicode[Times]{x3B2}}$ plaques. Furthermore, since amide B enables rapid imaging, we discuss its potential as a novel fingerprint for diagnostic applications.

description: We study the zero temperature phase diagram of hard core bosons in two dimensions subjected to three types of background potentials: staggered, uniform, and random. In all three cases there is a quantum phase transition from a superfluid (at small potential) to a normal phase (at large potential), but with different universality classes. As expected, the staggered case belongs to the XY universality, while the uniform potential induces a mean field transition. The disorder driven transition is clearly different from both; in particular, we find z~1.4, ν~1, and β~0.6.

description: Device-independent quantum key distribution (DIQKD) exploits the violation of a Bell inequality to extract secure key even if the users' devices are untrusted. Currently, all DIQKD protocols suffer from the secret key capacity bound, i.e., the secret key rate scales linearly with the transmittance of two users. Here we propose a heralded DIQKD scheme based on entangled coherent states to improve entangling rates whereby long-distance entanglement is created by single-photon-type interference. The secret key rate of our scheme can significantly outperform the traditional two-photon-type Bell-state measurement scheme and, importantly, surpass the above capacity bound. Our protocol therefore is an important step towards a realization of DIQKD and can be a promising candidate scheme for entanglement swapping in future quantum internet.

description: In order to simulate the motion of heavy equipment used in the forestry industry for the purpose of human factors and teleoperation research, we have designed a six degrees-of-freedom, hydraulic, one person motion simulator. In this thesis we derive the inverse kinematics and the jacobian of the platform. We also derive the forward kinematics of the platform using Newton's method and address workspace issues from the point of view of a "singularity boundary." In addition, we look at platform dynamics including the design of the hydraulic actuation system. Based on the results of dynamic simulations, we expect that this motion simulator will provide 9.8 m/s² , 400°/s² accelerations and 1 m/s, 30°/s speeds to a 250 kg payload with 1 m, 45° displacements from a nominal center.

description: Dynamical mean-field approximation with explicit pairing is utilized to study the properties of a two-component Fermi gas at unitarity. The problem is approximated by the lattice Hubbard Hamiltonian, and the continuum limit is realized by diluting the lattice. We have found that at zero temperature the predictions of this theory for the energy and the pairing gap agree remarkably well with the results of full numerical Monte-Carlo simulations. Investigating the evolution of the system with temperature we identify the existence of a second order phase transition associated with a jump in the heat capacity and the collapse of the pairing gap.

description: Overlay measurements are a critical part of modern semiconductor fabrication, but overlay targets have not scaled down in the way devices have. In this work, we produce overlay targets with very small footprint, consisting of just a few scattering nanoparticles in two separate device layers. Using moiré patterns to deterministically generate many overlay errors on a single chip, we demonstrate successful readout of the relative displacement between the two layers and show that calibration on one realization of the targets can be used for overlay measurements on subsequent instances. Our results suggest using greater quantities of smaller overlay targets may benefit performance both directly and through finer sampling of deformation.

Adaptive trellis-coded modulation for mobile communications
Creators: name: Alamouti, Siavash Massoumi
Publisher: name: University of British Columbia
Year: 2008

description: An adaptive scheme for trellis-coded modulation of MPSK signals called adaptive trellis-coded multiple-phase-shift-keying (ATCMPSK) is proposed for Rayleigh fading channels. The adaptive scheme employs a slightly modified rate 1/2 convolutional encoder and the corresponding Viterbi decoder to realize a family of codes of different rates which are employed according to channel conditions. During poor channel conditions, trellis-coded QPSK (TCQPSK) together with repetition schemes are employed. As channel conditions improve, higher rate schemes such as trellis-coded 16PSK are used. An interleaving/deinterleaving method suitable for the adaptive scheme is proposed. Theoretical bounds for the error performance and throughput of the proposed adaptive scheme are derived, and are compared against the simulation results. Simulations have been performed to measure the performance of the scheme for different parameters and nonideal conditions. It is shown that ATCMPSK results in considerable improvement in bit-error-rate (BER) performance of MPSK signals. Under ideal conditions, gains in the range of 3 — 20 dB are achieved over conventional fixed rate trellis-coded schemes.

description: Source code plagiarism is a long-standing issue in tertiary computer science education. Many source code plagiarism detection tools have been proposed to aid in the detection of source code plagiarism. However, existing detection tools are not robust to pervasive plagiarism-hiding transformations, and as a result can be inaccurate in the detection of plagiarised source code. This article presents BPlag, a behavioural approach to source code plagiarism detection. BPlag is designed to be both robust to pervasive plagiarism-hiding transformations, and accurate in the detection of plagiarised source code. Greater robustness and accuracy is afforded by analysing the behaviour of a program, as behaviour is perceived to be the least susceptible aspect of a program impacted upon by plagiarism-hiding transformations. BPlag applies symbolic execution to analyse execution behaviour and represent a program in a novel graph-based format. Plagiarism is then detected by comparing these graphs and evaluating similarity scores. BPlag is evaluated for robustness, accuracy and efficiency against 5 commonly used source code plagiarism detection tools. It is then shown that BPlag is more robust to plagiarism-hiding transformations and more accurate in the detection of plagiarised source code, but is less efficient than compared tools.

description: Topological semimetals are a new class of metallic materials, which exist at band fillings that ordinarily correspond to insulators or compensated accidental semimetals with zero Luttinger volume. Their metallicity is a result of nontrivial topology in momentum space and crystal symmetry, wherein topological charges may be assigned to point band-touching nodes, preventing gap opening, unless protecting crystal symmetries are violated. These topological charges, however, are defined from noninteracting band eigenstates, which raises the possibility that the physics of topological semimetals may be modified qualitatively by electron-electron interactions. Here we ask the following question: what makes the topological semimetals nontrivial beyond band theory? Alternatively, can strong electron-electron interactions open a gap in topological semimetals without breaking the protecting symmetries or introducing topological order? We demonstrate that the answer is generally no, and what prevents it is their topological response, or quantum anomalies. While this is familiar in the case of magnetic Weyl semimetals, where the topological response takes the form of an anomalous Hall effect, analogous responses in other types of topological semimetals are more subtle and involve crystal symmetry as well as electromagnetic gauge fields. Physically these responses are detectable as fractional symmetry charges induced on certain gauge defects. We discuss the cases of type-I Dirac semimetals and time-reversal invariant Weyl semimetals in detail. For type-I Dirac semimetals, we also show that the anomaly vanishes, in a nontrivial manner, if the momenta of the Dirac nodes satisfy certain exceptional conditions.

description: The evolution of the magnetic moment in iron clusters containing 20 to 400 atoms is investigated using first-principles numerical calculations based on density-functional theory and real-space pseudopotentials. Three families of clusters are studied, characterized by the arrangement of atoms: icosahedral, body-centered cubic centered on an atom site, and body-centered cubic centered on the bridge between two neighboring atoms. We find an overall decrease of magnetic moment as the clusters grow in size towards the bulk limit. Clusters with faceted surfaces are predicted to have magnetic moment lower than other clusters with similar size. As a result, the magnetic moment is observed to decrease as function of size in a non-monotonic manner, which explains measurements performed at low temperatures.

description: We perform an analysis in harmonic space of the Dark Energy Survey Year 1 Data (DES-Y1) galaxy clustering data using products obtained for the real-space analysis. We test our pipeline with a suite of lognormal simulations, which are used to validate scale cuts in harmonic space as well as to provide a covariance matrix that takes into account the DES-Y1 mask. We then apply this pipeline to DES-Y1 data taking into account survey property maps derived for the real-space analysis. We compare with real-space DES-Y1 results obtained from a similar pipeline. We show that the harmonic space analysis we develop yields results that are compatible with the real-space analysis for the bias parameters. This verification paves the way to performing a harmonic space analysis for the upcoming DES-Y3 data.

description: The ground-state properties of neutron-rich 106Nb and its beta decay into 106Mo have been studied using the CARIBU radioactive-ion-beam facility at Argonne National Laboratory. Niobium-106 ions were extracted from a 252Cf fission source and mass separated before being delivered as low-energy beams to the Canadian Penning Trap, as well as the X-Array and SATURN beta-decay-spectroscopy station. The measured 106Nb ground-state mass excess of -66202.0(13) keV is consistent with a recent measurement but has three times better precision; this work also rules out the existence of a second long-lived, beta-decaying state in 106Nb above 5 keV in excitation energy. The decay half-life of 106Nb was measured to be 1.097(21) s, which is 8% longer than the adopted value. The level scheme of the decay progeny, 106Mo, has been expanded up to approximately 4 MeV. The distribution of decay strength and considerable population of excited states in 106Mo of J >= 3 emphasises the need to revise the adopted Jpi = 1- ground-state spin-parity assignment of 106Nb; it is more likely to be J => 3.

Signatures of the Unruh effect from electrons accelerated by ultra-strong laser fields

description: We calculate the radiation resulting from the Unruh effect for strongly accelerated electrons and show that the photons are created in pairs whose polarizations are maximally entangled. Apart from the photon statistics, this quantum radiation can further be discriminated from the classical (Larmor) radiation via the different spectral and angular distributions. The signatures of the Unruh effect become significant if the external electromagnetic field accelerating the electrons is not too far below the Schwinger limit and might be observable with future facilities. Finally, the corrections due to the birefringent nature of the QED vacuum at such ultra-high fields are discussed. PACS: 04.62.+v, 12.20.Fv, 41.60.-m, 42.25.Lc.

The impact of storage conditions on the stability of clinical and experimental pharmaceuticals

description: To ensure a drug exhibits maximum efficacy and does not compromise patient acceptability or safety, it is essential to consider its physical, chemical, and biological stability outside of the body. Factors that can impact pharmaceutical stability include exposure to different environmental conditions (e.g. heat, light) and chemical processes (e.g. oxidation, hydrolysis) during transport, storage, and use. While pharmaceutical companies provide basic storage instructions, the impact of exposure to conditions that fluctuate from those recommended is not always evident. The aim of the investigations that form these doctoral studies was to determine the effect of different storage conditions, including solution pH and temperature, on the stability of a range of pharmaceuticals. These included clinically-used drugs, specifically remifentanil (an opioid analgesic), propofol (a short-acting anaesthetic), and tenecteplase (a thrombolytic agent), as well as an experimental plant extract still in development, EBC-46 (found to exhibit both anticancer and wound-healing properties). The findings of the studies demonstrate that even minor changes in the storage environment can have a substantial impact on the pharmaceutical stability of these diverse agents, therefore controlling this environment is crucial in ensuring full potency is retained long term.

description: This pre-registration is for the data collection procedures of the ExAMS Study. In this project, we aim to investigate people’s emotional functioning (including emotions, appraisals, emotion regulation motives and strategy use) over the course of an uncertain event. We will address this aim in an academic context by following medical students before and after their end-of-year exams. Using experience sampling methods (ESM), we will survey medical students multiple times a day across three time periods: (1) in the lead up to their first exam (the anticipation period), (2) while they wait for their end-of-year results (the uncertain waiting period), and (3) after they receive their end-of-year results (the certain outcome period).
Yukawa potential for realistic prediction of Hubbard and Hund interaction parameters for transition metals

description: The generalized Hubbard model is an important theoretical model for modeling strongly correlated materials. To be able to theoretically predict the properties of the materials, the model requires Hubbard's $U$ and Hund's $J$ parameter that represent the on-site Coulomb and exchange interaction, respectively. For bare Coulomb interactions, the analytic expression of $U$ and $J$ are analytically described by Racah's $A,B,C$ parameters. However, the values of $U$ are too large for transition-metal-based materials. To obtain more accurate values for realistic materials, we employ a Yukawa-type screened Coulomb interaction, characterized by screening constant $λ$. We characterize $λ$ for transition metals. The modified $A,B,C$ parameters give a more realistic $U$ and $J$ values.
