Insights into the effect of blood pressure and pregnancy on the PPG signal
Creators: name: Ramos Macias, Barbara Monserrat
Publisher: name: University of British Columbia
Year: 2018

description: Introduction: Hypertension in pregnancy, characterized by high blood pressure, is one of the three most common causes of maternal death. Photoplethysmography (PPG) is a portable, non-invasive and low-cost technique, which might have the potential to detect hypertension in pregnancy along with measuring three vital signs: oxygen saturation, heart rate, and respiratory rate. Currently, efforts have been made to estimate blood pressure and detect hypertension with the PPG signal. Objectives: The primary objective of this study is to describe the effect of pregnancy and blood pressure on the PPG signal. Methods: We calculated the average pulse per month of gestational age from 5,072 PPG signals of normotensive women to create a visual representation of a normal pregnancy effect on the PPG morphology. We fitted a linear model using the gestational age, blood pressure, and their interaction to predict PPG features. The PPG features were extracted from 11,412 PPG signals of pregnant women. The PPG features were calculated using four algorithms developed to locate the: dicrotic notch, diastolic peak, systolic peak, start of the pulse, and second derivative waves. Results: We observed PPG morphology changes based on the gestational age in normal pregnancy. The association with blood pressure described in the literature for non-pregnant subjects of some PPG features such as heart rate can change in pregnancy based on the gestational age. The obtained results of the four algorithms are: 1) pulse location algorithm with an accuracy of 97.67% and 98.1% for the start of the pulse and systolic peak location, respectively; 2) pulse verification algorithm improved pulse location positive predictivity; 3) equal accuracy between the ʻaʼ and ʻbʼ waves and the pulses location; and 4) reliable dicrotic notch, diastolic peak and ʻeʼ location based on the comparison with a high-performance dicrotic notch algorithm and visual inspection. Conclusion: The normal cardiovascular changes seen during pregnancy consistently affect the PPG signal and can be visually represented. The gestational age has a significant effect on the PPG detection of hypertension in pregnant women.

description: FIRE DANCING, a collection of personal essays, tells the story of my experience with mental illness. The first section depicts my experience with my first bipolar episode, allowing the reader to experience the ups, downs and new worries with me as they unfold. The second section describes my childhood, my family life, and the hints of mental health problems around me, both in my family's behavior and my own. I show how anxiety, depression, mania and addiction all showed up at the holiday dinner table, the unspoken members of our family. The third section depicts my experience watching a lover's brain unravel, unable to help as his fractured mind can no longer make sense of reality. Throughout the work, I take a close look at why mental illness is kept so silent­ particularly in families-and why it is so important to start talking.

description: The solution of the null non-radial geodesic in a Schwarzschild-de Sitter background is revisited. The gravitational bending of a light ray is affected by the cosmological constant, in agreement with the findings of some previous investigations. The present study confirms that the leading correction term depends directly not only on the cosmological constant but also on the impact parameter and on the angular distance to the source. Using the resulting lens equation, the projected mass of the lens was estimated for several systems displaying Einstein rings. Corrections on masses due to the cosmological constant are, on the average, of the order of 2%, indicating that they are not completly negligible for lens systems at cosmological distances.

Publisher: name: Zenodo
Year: 2023

description: Cavum Septum Pellucidum (CSP) cysts are considered normal anatomic variants, comprising as many as 15% of the adult and 85% of pediatric populations. On rare occasions, the cavum can obstruct CSF outflow from the lateral ventricles causing elevated intracranial pressure (ICP) and headaches. The purpose of this paper is to present a challenging case of new onset symptomatic CSP in a previously healthy adult male without papilledema and elevated ICP detected by transcranial Doppler (TCD) ultrasonography.

description: We present a dating method for deep-sea sediments that uses the natural radionuclide 230Th (half-life 75,380 years) in analogy to 210Pb with the constant rate of supply (CRS) model. Using an example from the western Indian sector of the Southern Ocean, we demonstrate how sets of values of 230Th, 232Th, and U isotopes activities can supply absolute age information for the last ~450,000 years, given a sufficient precision, resolution, and depth coverage of the analytical data in a suitable core. An assessment of age uncertainties resulting from analytical errors using a Monte Carlo approach and an analytical solution for error propagation shows good agreement. We also investigate errors due to a violation of model assumptions by variable focusing of deep-sea sediments by means of a simulated core. Finally, we use real examples from independently dated sediment cores containing carbonate, using previously existing 230Th data, to test the approach. The consideration of the systematic errors and the examples suggests that the uncertainties are smallest in the central part of the record and that the variability of focusing conditions controls the accuracy of the 230Th CRS dates. Our own example demonstrates an excellent agreement of the 230Th CRS method with independent age constraints, adding an important tool for dating marine records that does not depend on the presence of carbonate. The obtained values are also suitable to calculate 230Th-normalized preserved vertical rain rates of various sedimentary compounds, permitting an improved quantitative comparison of marine paleorecords with other archives like ice cores.

description: An efficient and versatile implementation of offline multiple hypothesis tracking with Algorithm X for optimal association search was developed using Python. The code is intended for scientific applications that do not require online processing. Directed graph framework is used and multiple scans with progressively increasing time window width are used for edge construction for maximum likelihood trajectories. The current version of the code was developed for applications in multiphase hydrodynamics, e.g. bubble and particle tracking, and is capable of resolving object motion, merges and splits. Feasible object associations and trajectory graph edge likelihoods are determined using weak mass and momentum conservation laws translated to statistical functions for object properties. The code is compatible with n-dimensional motion with arbitrarily many tracked object properties. This framework is easily extendable beyond the present application by replacing the currently used heuristics with ones more appropriate for the problem at hand. The code is open-source and will be continuously developed further.

description: Neodymium (Nd) isotopes extracted from authigenic sediment phases are increasingly used as a proxy for past variations in water mass provenance. To better constrain the controls of water mass provenance and nonconservative effects on the archived Nd isotope signal, we present a new depth transect of Nd isotope reconstructions from the Blake Bahama Outer Ridge along the North American continental margin covering the past 30 ka. We investigated five sediment cores that lie directly within the main flow path of the Deep Western Boundary Current, a major advection route of North Atlantic Deep Water. We found offsets between core tops and seawater Nd isotopic compositions that are observed elsewhere in the Northwest Atlantic. A possible explanation for this is the earlier suggested redistribution of sediment by nepheloid layers at intermediate as well as abyssal depths, transporting material downslope and along the continental margin. These processes potentially contributed to Nd isotope excursions recorded in Northwest Atlantic sediment cores during the Bølling-Allerød and early Holocene. An Atlantic-wide comparison of Nd isotope records shows that the early Holocene excursions had an additional contribution from conservative advection of unradiogenic dissolved Nd. Nevertheless, the trends of the Nd isotope records are in general agreement with previous reconstructions of water mass provenance from the entire Atlantic and also reveal millennial-scale changes during the last deglaciation in temporal high resolution, which have rarely been reported before. Further, the new records confirm that during cold periods the Northwest Atlantic was bathed by an increased contribution of southern sourced water.

description: Cyberattacks can cause a severe impact on power systems unless detected early. However, accurate and timely detection in critical infrastructure systems presents challenges, e.g., due to zero-day vulnerability exploitations and the cyber-physical nature of the system coupled with the need for high reliability and resilience of the physical system. Conventional rule-based and anomaly-based intrusion detection system (IDS) tools are insufficient for detecting zero-day cyber intrusions in the industrial control system (ICS) networks. Hence, in this work, we show that fusing information from multiple data sources can help identify cyber-induced incidents and reduce false positives. Specifically, we present how to recognize and address the barriers that can prevent the accurate use of multiple data sources for fusion-based detection. We perform multi-source data fusion for training IDS in a cyber-physical power system testbed where we collect cyber and physical side data from multiple sensors emulating real-world data sources that would be found in a utility and synthesizes these into features for algorithms to detect intrusions. Results are presented using the proposed data fusion application to infer False Data and Command injection-based Man-in- The-Middle (MiTM) attacks. Post collection, the data fusion application uses time-synchronized merge and extracts features followed by pre-processing such as imputation and encoding before training supervised, semi-supervised, and unsupervised learning models to evaluate the performance of the IDS. A major finding is the improvement of detection accuracy by fusion of features from cyber, security, and physical domains. Additionally, we observed the co-training technique performs at par with supervised learning methods when fed with our features.

Group event recognition in ice hockey

Year: 2018

description: With the success of deep learning in computer vision community, most approaches for group activity recognition in sports started relying on Convolutional Neural Networks (CNN) and Recurrent Neural Networks (RNN). However, how to model the interactions among players and the interactions between players and the scene remains a challenging problem. In order to better model these interactions, we propose two models. Our first model combines features of all players in a scene through an attention mechanism. The aggregated feature is then concatenated with the feature of the frame and passed through an RNN to generate the final prediction. In our second model, we designed a spatial grid feature and a temporal grid feature calculated from appearance features and motion features of all players in a scene, as well as their locations. We then apply CNNs to the spatial grid feature, the temporal grid feature, target frame of the scene (the frame at which the event happens), and the stack of optical flow containing the target frame separately. Results from the four streams are fused through score fusion to make the final prediction. Inputs to our models are: the target frame image, a stack of optical flow images, bounding boxes of players and coordinates of players calculated from homography matrix of the frame. We evaluated the two models on an Ice Hockey dataset, and results show that both models produced promising results. We also provide a possible solution for event detection in a more general setting.

description: Supersymmetric Grand Unified Theories (SGUTs) have achieved some degree of success, already present in the minimal models (with SU(5) or SO(10)). However, there are open problems that suggest the need to incorporate more elaborate constructions, specifically the use of higher-dimensional representations in the Higgs sector. For example, a $45$ representation of SU(5) is often included to obtain correct mass relations for the first and second families of d-type quarks and leptons. When one adds these higher-dimensional Higgs representations one must verify the cancellation of anomalies associated to their fermionic partners. One possible choice, free of anomalies, include both $45,\overline{45}$ representations to cancel anomalies. We review the necessary conditions for the cancellation of anomalies and discuss the different possibilities for supersymmetric SU(5) models. Alternative anomaly-free combinations of Higgs representations, beyond the usual vectorlike choice, are identified, and it is shown that their corresponding $β$ functions are not equivalent. Although the unification of gauge couplings is not affected, the introduction of multidimensional representations leads to different scenarios for the perturbative validity of the theory up to the Planck scale. We study the effect on the evolution of the gauge coupling up to the Planck scale due to the different sets of fields and representations that can render an anomaly-free model.

description: We study the existence of traveling wave solutions for a diffusive predator-prey system. The system considered in this paper is governed by a Sigmoidal response function which is more general than those studied previously. Our method is an improvement to the original method introduced in the work of Dunbar \cite{Dunbar1,Dunbar2}. A bounded Wazewski set is used in this work while unbounded Wazewski sets were used in \cite{Dunbar1,Dunbar2}. The existence of traveling wave solutions connecting two equilibria is established by using the original Wazewski's theorem which is much simpler than the extended version in Dunbar's work.

description: The problem of axiomatization of physics formulated by Hilbert as early as 1900 and known as the Sixth Problem of Hilbert is nowadays even more topical than at the moment of its formulation. Axiomatic inconsistency of classic, quantum, and geometrized relativistic physics of the general relativistic theory does not in the least fade away, but on the contrary, becomes more pronounced each year. This naturally evokes the following questions: 1. Is it possible, without drastically changing the mathematics apparatus, to set up the axiomatics of physics so as to transform physics, being presently a multitude of unmatched theories with inconsistent axiomatics, into an integrated science? 2. Is it possible, maybe through expanding their scopes, to generalize of transform the existing axiomatics into an integral system of axioms in such a manner that existing axiomatics of inconsistent theories would follow there from as a particular case?

description: Among the key features of hot and dense QCD matter produced in ultra-relativistic heavy-ion collisions at RHIC is its very low shear viscosity, indicative of the properties of a near-ideal fluid, and a large opacity demonstrated by jet energy loss measurements. In this work, we utilize a microscopic transport model based on the Boltzmann equation with quark and gluon degrees of freedom and cross sections calculated from perturbative Quantum Chromodynamics to simulate an ideal Quark-Gluon-Plasma in full thermal and chemical equilibrium. We then use the Kubo formalism to calculate the shear viscosity to entropy density ratio of the medium as a function of temperature and system composition. One of our key results is that the shear viscosity over entropy-density ratio $η/s$ becomes invariant to the chemical composition of the system when plotted as a function of energy-density instead of temperature.

description: QCD sum rules involving mixed inverse moment integration kernels are used in order to determine the running charm-quark mass in the $\bar{MS}$ scheme. Both the high and the low energy expansion of the vector current correlator are involved in this determination. The optimal integration kernel turns out to be of the form $p(s) = 1 - (s_0/s)^2$, where $s_0$ is the onset of perturbative QCD. This kernel enhances the contribution of the well known narrow resonances, and reduces the impact of the data in the range $s \simeq 20 - 25 GeV^2$. This feature leads to a substantial reduction in the sensitivity of the results to changes in $s_0$, as well as to a much reduced impact of the experimental uncertainties in the higher resonance region. The value obtained for the charm-quark mass in the $\bar{MS}$ scheme at a scale of 3 GeV is $\bar{m}_c (3 GeV) = 987 \pm 9 MeV$, where the error includes all sources of uncertainties added in quadrature.

description: Two particle collisions close to the horizon of the rotating nonextremal black hole are analyzed. It is shown that high energy of the order of the Grand Unification scale in the centre of mass of colliding particles can be obtained when there is a multiple collision - the particle from the accretion disc gets the critical momentum in first collision with the other particle close to the horizon and then there is a second collision of the critical particle with the ordinary one. High energy occurs due to a great relative velocity of two particles and a large Lorentz factor. The dependence of the relative velocity on the distance to horizon is analyzed, the time of movement from the point in the accretion disc to the point of scattering with large energy as well as the time of back movement to the Earth are calculated. It is shown that they have reasonable order.

Inter-aural difference norms for wideband absorbance (WBA) : potential for identifying otosclerosis
Creators: name: Schlagintweit, Martine
Publisher: name: University of British Columbia
Year: 2018

description: Purpose: Wideband acoustic immittance (WAI) is a field of noninvasive diagnostic measures that are used to evaluate the status of the middle ear. Wideband absorbance (WBA) is a WAI tool that distinguishes normally-hearing from pathological middle ears with a high level of diagnostic accuracy. This work aims to further improve the diagnostic efficiency of WBA, by providing a set of normative data which represents the typical inter-aural difference of WBA in adults of Caucasian, Asian and Mixed ethnicities. Design: This retrospective analysis examined records of WBA obtained from normally-hearing adults (N=122; mean age= 24.16 yrs) using the Titan by Interacoustics immittance equipment. Norms were established for individual ear measures, and the inter-aural difference of WBA measured within-subjects. A mixed model ANOVA was used to analyze how normative WBA measures are affected by factors of ethnicity, gender, and test pressurization method. A comparison of the diagnostic efficacy of the two WBA measurements was conducted with an ROC analysis, using WBA records from 28 subjects with surgically confirmed otosclerosis as a clinical group. Results: The ROC analysis confirmed that diagnostic accuracy of WBA individual ear and inter- aural difference measures was equal for the detection of otosclerosis; however, these measurements may provide complementary information regarding middle ear status. WBA norms based on individual ear data varied significantly depending on ethnicity, gender, and test pressurization method across frequencies. WBA norms based on inter-aural difference values only varied significantly with test pressurization method across frequencies, though the difference was small and likely does not have any clinical relevance, at least for the detection of otosclerosis. iii Conclusion: WBA norms based on inter-aural difference values did not depend on population- based factors of ethnicity or gender; the same set of normative data may be used reliably across these populations. Parameterization of norms for individual ear WBA data is recommended based on ethnicity, gender and test pressurization method. Inter-aural difference norms for WBA may be instrumental in interpreting immittance results for individuals with unilateral conductive pathology, or for populations for which other forms of normative data are not available.

description: Given the non-graph-changing Hamiltonian $\widehat{H[N]}$ in Loop Quantum Gravity (LQG), $\langle\widehat{H[N]}\rangle$, the coherent state expectation value of $\widehat{H[N]}$, admits an semiclassical expansion in $\ell^2_{\rm p}$. In this paper, as presenting the detailed derivations of our previous work arXiv:2012.14242, we explicitly compute the expansion of $\langle\widehat{H[N]}\rangle$ to the linear order in $\ell^2_{\rm p}$ on the cubic graph with respect to the coherent state peaked at the homogeneous and isotropic data of cosmology. In our computation, a powerful algorithm is developed, supported by rigorous proofs and several theorems, to overcome the complexity in the computation of $\langle \widehat{H[N]} \rangle$. Particularly, some key innovations in our algorithm substantially reduce the complexity in computing the Lorentzian part of $\langle\widehat{H[N]}\rangle$. Additionally, some quantum correction effects resulting from $\langle\widehat{H[N]}\rangle$ in cosmology are discussed at the end of this paper.

description: We present an analysis of the rotation of young stars in the associations Cepheus OB3b, NGC 2264, NGC 2362 and the Orion Nebula Cluster (ONC). We discover a correlation between rotation rate and position in a colour-magnitude diagram (CMD) such that stars which lie above an empirically determined median pre-main sequence rotate more rapidly than stars which lie below this sequence. The same correlation is seen, with a high degree of statistical significance, in each association studied here. If position within the CMD is interpreted as being due to genuine age spreads within a cluster, then the stars above the median pre-main sequence would be the youngest stars. This would in turn imply that the most rapidly rotating stars in an association are the youngest, and hence those with the largest moments of inertia and highest likelihood of ongoing accretion. Such a result does not fit naturally into the existing picture of angular momentum evolution in young stars, where the stars are braked effectively by their accretion discs until the disc disperses. Instead, we argue that, for a given association of young stars, position within the CMD is not primarily a function of age, but of accretion history. We show that this hypothesis could explain the correlation we observe between rotation rate and position within the CMD.

description: Despite the great efforts to find an effective way for COVID-19 prediction, the virus nature and mutation represent a critical challenge to diagnose the covered cases. However, developing a model to predict COVID-19 via Chest X-Ray (CXR) images with accurate performance is necessary to help in early diagnosis. In this paper, a hybrid quantum-classical convolutional Neural Networks (HQCNN) model used the random quantum circuits (RQCs) as a base to detect COVID-19 patients with CXR images. A collection of 6952 CXR images, including 1161 COVID-19, 1575 normal, and 5216 pneumonia images, were used as a dataset in this work. The proposed HQCNN model achieved higher performance with an accuracy of 98.4\% and a sensitivity of 99.3\% on the first dataset cases. Besides, it obtained an accuracy of 99\% and a sensitivity of 99.7\% on the second dataset cases. Also, it achieved accuracy, and sensitivity of 88.6\%, and 88.7\%, respectively, on the third multi-class dataset cases. Furthermore, the HQCNN model outperforms various models in balanced accuracy, precision, F1-measure, and AUC-ROC score. The experimental results are achieved by the proposed model prove its ability in predicting positive COVID-19 cases.

description: The Constrained Adiabatic Trajectory Method (CATM) allows us to compute solutions of the time-dependent Schrödinger equation using the Floquet formalism and Fourier decomposition, using matrix manipulation within a non-orthogonal basis set, provided that suitable constraints can be applied to the initial conditions for the Floquet eigenstate. A general form is derived for the inherent absorbing potential, which can reproduce any dispersed boundary conditions. This new artificial potential acting over an additional time interval transforms any wavefunction into a desired state, with an error involving exponentially decreasing factors. Thus a CATM propagation can be separated into several steps to limit the size of the required Fourier basis. This approach is illustrated by some calculations for the $H_2^+$ molecular ion illuminated by a laser pulse.

The NIRSPEC Ultracool Dwarf Radial Velocity Survey

description: We report the results of an infrared Doppler survey designed to detect brown dwarf and giant planetary companions to a magnitude-limited sample of ultracool dwarfs. Using the NIRSPEC spectrograph on the Keck II telescope, we obtained approximately 600 radial velocity measurements over a period of six years for a sample of 59 late-M and L dwarfs spanning spectral types M8/L0 to L6. A subsample of 46 of our targets have been observed on three or more epochs. We rely on telluric CH4 absorption features in the Earth's atmosphere as a simultaneous wavelength reference and exploit the rich set of CO absorption features found in the K-band spectra of cool stars and brown dwarfs to measure radial velocities and projected rotational velocities. For a bright, slowly rotating M dwarf standard we demonstrate a radial velocity precision of 50 m/s, and for slowly rotating L dwarfs we achieve a typical radial velocity precision of approximately 200 m/s. This precision is sufficient for the detection of close-in giant planetary companions to mid-L dwarfs as well as more equal mass spectroscopic binary systems with small separations (a<2 AU). We present an orbital solution for the subdwarf binary LSR1610-0040 as well as an improved solution for the M/T binary 2M0320-04. We also combine our radial velocity measurements with distance estimates and proper motions from the literature to estimate the dispersion of the space velocities of the objects in our sample. Using a kinematic age estimate we conclude that our UCDs have an age of 5.0+0.7-0.6 Gyr, similar to that of nearby sun-like stars. We simulate the efficiency with which we detect spectroscopic binaries and find that the rate of tight (a<1 AU) binaries in our sample is 2.5+8.6-1.6%, consistent with recent estimates in the literature of a tight binary fraction of 3-4%.

description: The percolation of strings gives a good description of the RHIC experimental data on the elliptic flow, v2 and predicted a rise on the integrated v2 of the order of 25% at LHC such as it has been experimentally obtained. We show that the dependence of v2 on pT for RHIC and LHC energies is approximately the same as it has been observed, for all the centralities. We show the results for different particles and the dependence of v2 on the centralities and rapidity. Our results are compatible with an small value of the ratio eta/s in the whole energy range such as it was expected in the percolation framework.

description: Abstract
This research study explores the intricate relationship between freedom and happiness as depicted in Jonathan Franzen's novel Freedom. The narrative of the novel revolves around the multigenerational history of the Berglund family in Minnesota, USA. With a blend of humor and cruelty, the story vividly portrays the pleasures and burdens of liberty in the midst of the adventures of adolescence. The easy way people compromise at middle age, the changes suburban expansion brings in the life of individuals, the consequences of power through poignant storytelling-Franzen offers a profound and thought-provoking solution. The author presents modern times, describing failures and delights that individuals encounter as they live in an increasingly perplexing environment. There are different types of characters, each grappling with his own interpretation of freedom and its implications. Franzen investigates the nuances of individual freedom and explains the ways characters struggle hard to attain it. The Berglund family represents multigenerational history that serves as the microcosm of the broader American society. Readers are introduced to the complex relationship present among individuals who thrive hard to attain independence. The researcher seeks to shed light on the concepts maintained by individuals about freedom and different ways they adopt in order to attain happiness in life.

description: Exclusion from school is an issue of national and local concern. With more boys experiencing exclusion than girls the research is dominated by a male perspective. This research aimed to provide an in-depth exploration of the experience of girls who have been excluded and are currently attending Alternative Provisions (AP). A sense of belonging is linked to more positive outcomes therefore this research was underpinned by an exploration of the belonging these girls have experienced in their previous and current settings along with their hopes for the future. This exploratory research had a constructivist epistemology and an ontological position of relativism. It accepts that multiple realities are constructed through lived experience and individually constructed and focuses on the stories of three secondary age girls. The research took a narrative approach and a guided interview and life grids were used to support the gathering of data remotely. Participants’ narratives were re-storied according to Clandinin and Connelly’s (2000) threedimensional space, offering rich and detailed insights into the complexity of their experiences. In the second phase of analysis, the three storied narratives were analysed using narrative thematic analysis, and several themes and subthemes were identified for each of the research questions. The girls were found to experience higher levels of belonging in their alternative provision, feeling a lack of autonomy in their mainstream experiences. Positive teacher relationships contained the most powerful narratives. The girls found in the alternative provisions that male students can experience increased support from staff and that more resources were directed towards their experiences. The girls outlined hopes and aspirations for the future, but these were limited by a fear of a repeated experience of a lack of understanding around their needs. The implications of the research findings for both national strategy, Educational Psychology practice and Educational settings are discussed.

description: We give a parametrization with perfect subsets of $2^{\infty}$ of the abstract Ramsey theorem (see \cite{todo}) Our main tool is an extension of the parametrized version of the combinatorial forcing developed in \cite{nash} and \cite{todo}, used in \cite{mij} to the obtain a parametrization of the abstract Ellentuck theorem. As one of the consequences, we obtain a parametrized version of the Hales-Jewett theorem. Finally, we conclude that the family of perfectly ${\cal S}$-Ramsey subsets of $2^{\infty}\times {\cal R}$ is closed under the Souslin operation. {\bf Key words and phrases}: Ramsey theorem, Ramsey space, parametrization.
