Automatic landmark detection based on deep learning to reduce intra- and/or inter-observer variability error in hip range of motion analysis
Creators: name: Kilani, Khalil
Publisher: name: Zenodo
Year: 2023
Subjects: landmark detection, deep learning, hip range of motion, CT, MRI

description: Premature osteoarthritis in the hip joint can often be linked to femoral acetabular
 impingement or hip dysplasia. To assess the hip range of motion (ROM) and detect
 impingement positions between the acetabulum and proximal femur before considering
 surgical treatment, clinicians use a computer-assisted tool called hip ROM analysis.
 This requires 3D surface models of the pelvis, proximal femur, and distal femur, ob-
 tained through bone segmentation from original MRI or CT images. Traditionally, the
 hip ROM analysis involved manual selection of specific anatomical landmarks on these
 surface models to employ its collision detection algorithm, leading to potential varia-
 tions in the outcome due to user variance. To address this issue, this study utilized
 deep learning to automate the identification of these landmarks.
 Three convolutional neural networks were trained on manually segmented bone
 images from the pelvis, the proximal and distal femur using nnU-Net, an optimized
 open-source tool for medical image classification. To enable classification of 3D coor-
 dinates represented by a single voxel, 3D spheres were assigned distinct label values
 surrounding each landmark as ground truth. The center of the predicted 3D spheres
 was subsequently used as the landmark coordinate. Totally, 24 landmarks were pre-
 dicted. The trained networks were integrated into an algorithm that uses three seg-
 mentations from the pelvis, proximal and distal femur as input and stores the landmark
 coordinates in a XML file. To assess the effectiveness of the landmark automation in
 reducing inter-/intra-observer variability, a ROM-test was performed. This test in-
 volved 22 different leg positions and is employed by the clinicians when using the hip
 ROM analysis. The ROM-test was performed for a total of 15 patients with manually
 selected landmarks and with automated landmarks for comparison. Differences in im-
 pinging positions were recorded and further investigated to identify which landmarks
 caused these variations.
 The results showed that in 92% of the tested positions, no differences were found
 when using manual or automated landmarks. In 8% the differences were small, within
 5° to 10°. The mean error between the manual and automated landmarks across all
 landmarks was lower with 3.5 ±2.27mm compared to the intra-observer variability with
 4.32 ±2.78mm and the inter-observer variability with 4.3 ±2.88mm. This indicates
 that automated landmarks reduce user variability and can enhance the reliability of
 hip ROM analysis. The total run time of the algorithm was only one-third with 40
 seconds compared to manual selected landmarks for the same patient.

description: The logistic map is a paradigmatic dynamical system originally conceived to model the discrete-time demographic growth of a population, which shockingly, shows that discrete chaos can emerge from trivial low-dimensional non-linear dynamics. In this work, we design and characterize a simple, low-cost, easy-to-handle, electronic implementation of the logistic map. In particular, our implementation allows for straightforward circuit-modifications to behave as different one-dimensional discrete-time systems. Also, we design a coupling block in order to address the behavior of two coupled maps, although, our design is unrestricted to the discrete-time system implementation and it can be generalized to handle coupling between many dynamical systems, as in a complex system. Our findings show that the isolated and coupled maps' behavior has a remarkable agreement between the experiments and the simulations, even when fine-tuning the parameters with a resolution of $\sim 10^{-3}$. We support these conclusions by comparing the Lyapunov exponents, periodicity of the orbits, and phase portraits of the numerical and experimental data for a wide range of coupling strengths and map's parameters.

Atmospheric Circulation of Hot Jupiters: Dayside-Nightside Temperature Differences

description: The full-phase infrared light curves of low-eccentricity hot Jupiters show a trend of increasing dayside-to-nightside brightness temperature difference with increasing equilibrium temperature. Here we present a three-dimensional model that explains this relationship, in order to shed insight on the processes that control heat redistribution in tidally-locked planetary atmospheres. This three-dimensional model combines predictive analytic theory for the atmospheric circulation and dayside-nightside temperature differences over a range of equilibrium temperature, atmospheric composition, and potential frictional drag strengths with numerical solutions of the circulation that verify this analytic theory. This analytic theory shows that the longitudinal propagation of waves mediates dayside-nightside temperature differences in hot Jupiter atmospheres, analogous to the wave adjustment mechanism that regulates the thermal structure in Earth's tropics. These waves can be damped in hot Jupiter atmospheres by either radiative cooling or potential frictional drag. This frictional drag would likely be caused by Lorentz forces in a partially ionized atmosphere threaded by a background magnetic field, and would increase in strength with increasing temperature. Additionally, the amplitude of radiative heating and cooling increases with increasing temperature, and hence both radiative heating/cooling and frictional drag damp waves more efficiently with increasing equilibrium temperature. Radiative heating and cooling play the largest role in controlling dayside-nightside temperature temperature differences in both our analytic theory and numerical simulations, with frictional drag only important if it is stronger than the Coriolis force. As a result, dayside-nightside temperature differences in hot Jupiter atmospheres increase with increasing stellar irradiation and decrease with increasing pressure.

description: Exchanging data between different systems enables us to build new smart services and digitise various areas of our daily life. This digitalisation leads to more efficient usage of resources, and an increased monetary value. However, the connection of different systems also increases the number of potential vulnerabilities. The vulnerabilities on their own might be harmless, but attackers could build attack paths based on the combination of different vulnerabilities. Additionally, attackers might exploit existing access control policies to further propagate through the system. For analysing this dependency between vulnerabilities and access control policies, we extended an architecture description language (ADL) to model access control policies and specify vulnerabilities. We developed an attack propagation analysis operating on the extended ADL, which can help to determine confidentiality violations in a system. We evaluated our approach by analysing the accuracy and the effort compared to a manual analysis using different scenarios in three case studies. The results indicate that our analysis is capable of identifying attack paths and reducing the effort compared to manual detection.

description: Blood exhibits a heterogeneous nature of hematocrit, velocity, and effective viscosity in microcapillaries. Microvascular bifurcations have a significant influence on the distribution of the blood cells and blood flow behavior. This paper presents a simulation study performed on the two-dimensionalmotions and deformation of multiple red blood cells in microvessels with diverging and converging bifurcations. Fluid dynamics and membrane mechanics were incorporated. Effects of cell shape, hematocrit, and deformability of the cell membrane on rheological behavior of the red blood cells and the hemodynamics have been investigated. It was shown that the blood entering the daughter branch with a higher flow rate tended to receive disproportionally more cells. The results also demonstrate that red blood cells in microvessels experienced lateral migration in the parent channel and blunted velocity profiles in both straight section and daughter branches, and this effect was influenced by the shape and the initial position of the cells, the hematocrit, and the membrane deformability. In addition, a cell free region around the tip of the confluence was observed. The simulation results are qualitatively consistent with existing experimental findings. This study may provide fundamental knowledge for a better understanding of hemodynamic behavior of micro-scale blood flow.

description: Polar codes form a very powerful family of codes with a low complexity decoding algorithm that attain many information theoretic limits in error correction and source coding. These codes are closely related to Reed-Muller codes because both can be described with the same algebraic formalism, namely they are generated by evaluations of monomials. However, finding the right set of generating monomials for a polar code which optimises the decoding performances is a hard task and channel dependent. The purpose of this paper is to reveal some universal properties of these monomials. We will namely prove that there is a way to define a nontrivial (partial) order on monomials so that the monomials generating a polar code devised fo a binary-input symmetric channel always form a decreasing set. This property turns out to have rather deep consequences on the structure of the polar code. Indeed, the permutation group of a decreasing monomial code contains a large group called lower triangular affine group. Furthermore, the codewords of minimum weight correspond exactly to the orbits of the minimum weight codewords that are obtained from (evaluations) of monomials of the generating set. In particular, it gives an efficient way of counting the number of minimum weight codewords of a decreasing monomial code and henceforth of a polar code.

Observational Constraints on Planet Nine: Astrometry of Pluto and Other Trans-Neptunian Objects

description: We use astrometry of Pluto and other TNOs to constrain the sky location, distance, and mass of the possible additional planet (Planet Nine) hypothesized by Batygin and Brown (2016). We find that over broad regions of the sky, the inclusion of a massive, distant planet degrades the fits to the observations. However, in other regions, the fits are significantly improved by the addition of such a planet. Our best fits suggest a planet that is either more massive or closer than argued for by Batygin and Brown (2016) based on the orbital distribution of distant trans-neptunian objects (or by Fienga et al. (2016) based on range measured to the Cassini spacecraft). The trend to favor larger and closer perturbing planets is driven by the residuals to the astrometry of Pluto, remeasured from photographic plates using modern stellar catalogs (Buie and Folkner 2015), which show a clear trend in declination, over the course of two decades, that drive a preference for large perturbations. Although this trend may be the result of systematic errors of unknown origin in the observations, a possible resolution is that the declination trend may be due to perturbations from a body, additional to Planet Nine , that is closer to Pluto, but less massive than, Planet Nine .
Simulation of Quiet-Sun Hard X-rays Related to Solar Wind Superhalo Electrons

description: In this paper, we propose that the accelerated electrons in the quiet Sun could collide with the solar atmosphere to emit Hard X-rays (HXRs) via non-thermal bremsstrahlung, while some of these electrons would move upwards and escape into the interplanetary medium, to form a superhalo electron population measured in the solar wind. After considering the electron energy loss due to Coulomb collisions and the ambipolar electrostatic potential, we find that the sources of the superhalo could only occur high in the corona (at a heliocentric altitude $\gtrsim 1.9$ R$_\odot$ (the mean radius of the Sun)), to remain a power-law shape of electron spectrum as observed by STEREO at 1AU near solar minimum (Wang et al., 2012). The modeled quiet-Sun HXRs related to the superhalo electrons fit well to a power-law spectrum, $f \sim \varepsilon^{-γ}$, with an index $γ$ $\approx$ 2.0 - 2.3 (3.3 - 3.7) at 10 - 100 keV, for the warm/cold thick-target (thin-target) emissions produced by the downward-traveling (upward-traveling) accelerated electrons. These simulated quiet-Sun spectra are significantly harder than the observed spectra of most solar HXR flares. Assuming that the quiet-Sun sources cover 5% of the solar surface, the modeled thin-target HXRs are more than six orders of magnitude weaker than the RHESSI upper limit for quiet-Sun HXRs (Hannah et al., 2010). Using the thick-target model for the downward-traveling electrons, the RHESSI upper limit restricts the number of downward-traveling electrons to at most $\approx$3 times the number of escaping electrons. This ratio is fundamentally different from what is observed during solar flares associated with escaping electrons where the fraction of downward-traveling electrons dominates by a factor of 100 to 1000 over the escaping population.

description: Massive stars are luminous beacons that help us to extract information about the star formation history and the chemodynamical evolution of galaxies in the Universe. Our Galaxy is full of massive stars, which expend their short-lived existence within bright star-forming regions, depositing huge amounts of mechanical and radiative energy to the interstellar medium before they explode as energetic supernovae event. They are also the origin of the recently detected phenomena of gravitational waves, with the merger of a pair of their typical end products: black holes or neutron stars. The IACOB and OWN projects have collected a large database of high-resolution multi-epoch spectra of Galactic O and B-type stars, ~10000 spectra for more than 1000 OB stars. This unique spectroscopic dataset, once analyzed and interpreted with state-of-the-art tools and techniques will provide a new, global overview of the physical and evolutionary properties of massive stars in their early phases. In this contribution, I will present the results from the quantitative spectroscopic analysis of ~300 O stars targeted by the IACOB and OWN surveys (implying the largest sample of O Galactic O stars analyzed homogeneously, using modern automatized tools). I will put special emphasis on highlighting the impact of the GAIA mission in the determination of physical parameters of massive stars, with distance calculation of unprecedented precision for these bright objects. With this, we intend to revisit calibrations of stellar parameters with spectral type and luminosity class, and provide a homogeneous and statistically significant empirical anchor of the physical attributes of Galactic O-type stars.

description: The available diagnostics for atmospheric micro-plasmas remain limited and relatively complex to implement; so we present a radio-frequency technique for diagnosing a key parameter here. The technique allows one to estimate the dependencies of the electron density by measuring the RF-impedance of the micro-plasma and analyzing it with an appropriate equivalent circuit. This technique is inexpensive, can be used in real time and gives reasonable results for argon and helium DC micro-plasmas in holes over a wide pressure range. The electron density increases linearly with current in the expected range consistent with normal glow discharge behavior.
title: Spore germination in the fungus Syncephalastrum racemosum

description: The asexual part of the life cycle of the fungus Syncephalastrum racemosum was investigated using light microscopy, transmission and scanning electron microscopy. The structure and organisation of the vegetative mycelium and spore producing hyphae was studied in detail. Freeze-fracturing, surface replica, metal shadowing and thin sectioning techniques were used to investigate the ultrastrueture of dormant and germinated spore walls subjected to various sequential chemical treatments. The spore wall had a highly complex organisation, consisting of four, major ultrastructurally definable layers. (1) A surface layer consisting of a cross-patched network of rodlets, having a 25nm periodicity. (2) A plate-like layer covered by amorphous material.(3) A layer of thick 17»5nm diameter microfibrils. (4) An innermost layer of thin 8nm diameter microfibrils. The emergent germ tube has a smooth outer surface and an inner layer of thin microfibrils. The breakpoint between spore and germ tube is clearly delimited at various levels within the spore wall. Tentative identification of the wall layers showed: (1) the rodlet layer was mainly protein; (2) the thick microfibrils were probably a β-glucan; (3) the thin microfibrils were chitin. Freeze-fracturing of dormant and germinated spores revealed differences in plasmamembrane ultrastructure. Large particles (34nm) with complimentary large depressions (33nm) were present only in fractures of the plasmamembrane of dormant spores. During germination there is an increase in the numbers of small particles (8.4nm) in the membrane. The physiology of spore germination was studied in shake-flask and batch fermenter cultures. In the presence of glucose, spore swelling preceded outgrowth of germ tubes. Glucose was essential for initiation of these events. Swelling ceased quickly when glucose was removed. Analysis of size distributions within spore populations indicated that the larger spores germinated first. A self-inhibitor of germination was extracted from culture and spore washings, and was identified as nonanoic acid.

description: This communication case study explores the collaboration between Blossom Inner Private Limited and advertising agency Alende Design in creating an innovative advertising strategy for women's underwear products. The study employs Birkigt & Stadler's Corporate Identity and Corporate Image framework model to analyze the alignment of both companies' identities, identify gaps and objectives in the communication strategy, and propose improvements. Blossom, influenced by Christian principles and concerned about juvenile crime, sought to respect and empower women in their advertisements. Alende Design, aligning with the client's philosophy, aimed to use belief, values, and trust to emotionally influence the target market. The study analyzes how both companies' identities were aligned, leading to the development of a distinct campaign that refrains from exploiting female models and avoids showing sensual elements. It also discusses the importance of prioritizing purpose over profit to build a sustainable reputation and proposes a media strategy using social media platforms to enhance customer engagement. The study concludes by emphasizing the significance of effective communication strategies in repositioning a company's image and reputation.

description: Time domain surveys, whether in the form of wide-field photometric (like LSST) or spectroscopic (SDSS-V) surveys, will expand our knowledge in many aspects of stellar Astrophysics in the next decade. J-VAR constitutes a trade-off between such approximations, having a photometric-based approach but with some (low) spectral resolution around key stellar features thanks to its medium- and narrow-band filters (J0395, J0515, J0660, J0861). RR Lyrae stars, intimately tracers of old (>10 Gyr) stellar populations, are classical pulsators with periods between around 0.2 to 1.2 d. They pulsate mainly in two modes: the fundamental (RRab/RR0) and the first-overtone (RRc/RR1) modes. Although they are present in all the MW components, their number stands out in the halo. They are very fair distance indicators (following a well-known and tight luminosity-period-metallicity relation). In this contribution, we explore the capabilities of J-VAR data to analyze how the Spectral Energy Distributions (SEDs) of RR Lyrae stars vary with the phase and what can we learn from it about the physics of these classical pulsators.

description: I present analytical expressions for the cusp anomalous dimension in QCD through three loops in terms of elementary functions and ordinary polylogarithms. I observe interesting relations between the results at different loops and provide a conjecture for the $n$-loop cusp anomalous dimension in terms of the lower-loop results. I also present numerical results and simple approximate formulas for the cusp anomalous dimension relevant to top-quark production.

description: This letter studies parallel independent Gaussian channels with uncertain eavesdropper channel state information (CSI). Firstly, we evaluate the probability of zero secrecy rate in this system for (i) given instantaneous channel conditions and (ii) a Rayleigh fading scenario. Secondly, when non-zero secrecy is achievable in the low SNR regime, we aim to solve a robust power allocation problem which minimizes the outage probability at a target secrecy rate. We bound the outage probability and obtain a linear fractional program that takes into account the uncertainty in eavesdropper CSI while allocating power on the parallel channels. Problem structure is exploited to solve this optimization problem efficiently. We find the proposed scheme effective for uncertain eavesdropper CSI in comparison with conventional power allocation schemes.

description: Velazquez and Curilef have proposed a methodology to extend Monte Carlo algorithms that are based on canonical ensemble. According to our previous study, their proposal allows us to overcome slow sampling problems in systems that undergo any type of temperature-driven phase transition. After a comprehensive review about ideas and connections of this framework, we discuss the application a re-weighting technique to improve the accuracy of microcanonical calculations, specifically, the well-known multi-histograms method of Ferrenberg and Swendsen. As example of application, we reconsider the study of four-state Potts model on the square lattice $L\times L$ with periodic boundary conditions. This analysis allows us to detect the existence of a very small latent heat per site $q_{L}$ during the occurrence of temperature-driven phase transition of this model, whose size dependence seems to follow a power-law $q_{L}(L)\propto(1/L)^{z}$ with exponent $z\simeq0$.$26\pm0$.$02$. It is discussed the compatibility of these results with the continuous character of temperature-driven phase transition when $L\rightarrow+\infty$.

description: Morbus Parkinson ist eine neurologische Erkrankung, die langsam fortschreitet und bis heute nicht geheilt werden kann. Im Verlauf der Krankheit treten bei der Mehrheit der Betroffenen Stimm- und/oder Sprechprobleme auf, welche mit einer logopädischen Therapie gemildert werden können. Die Verbesserungen der Stimme und der Artikulation lassen sich messen und nachweisen, der persönliche Gewinn für die Betroffenen dagegen nicht. Diese Bachelorarbeit geht der Frage nach, inwiefern sich eine wirksame logopädische Intervention auf die subjektive Einschätzung der Lebensqualität in alltäglichen Gesprächssituationen auswirkt. Um die Forschungsfrage zu beantworten, wurde das Theoriewissen mittels Literaturrecherche erworben. Anschliessend wurde mit einer Morbus-Parkinson-Betroffenen je ein problemzentriertes Leitfadeninterview vor und nach der evidenzbasierten Dysarthrie-Therapie mit dem Lee Silverman Voice Treatment (LSVT LOUD®) durchgeführt. Die Aussagen der Betroffenen zeigen, dass sie durch die erzielten Verbesserungen wieder aktiv und mühelos an Alltagsgesprächen teilhaben kann. Die positiven Veränderungen stuft sie als grossen Gewinn für ihr Wohlbefinden ein. Daraus lässt sich ableiten, dass eine logopädische Therapie einen Zuwachs an Lebensqualität bewirken kann. Aufgrund dieser Erkenntnis ist es empfehlenswert, MorbusParkinson-Betroffenen mit einer Stimm- und/oder Sprechstörung zu raten, sich frühzeitig in logopädische Behandlung zu begeben.

description: Hazewinkel proved the Ditters conjecture that the algebra of quasisymmetric functions over the integers is free commutative by constructing a nice polynomial basis. In this paper we prove a structure theorem for the algebra of peak quasisymmetric functions (PQSym) over the integers. It provides a polynomial basis of PQSym over the rational field, different from Hsiao's basis, and implies the freeness of PQSym over its subring of symmetric functions spanned by Schur's Q-functions.

description: Das Thema Poltern ist in der Forschung, der Praxis und der Fachliteratur unterrepräsentiert. Es besteht eine grosse Unsicherheit in Bezug auf die logopädische Diagnostik und Therapie. Das Ziel dieser Arbeit ist die Entwicklung einer Förderspielsammlung als Therapiebaustein «Kommunikationsorganisation» der Zürcher integrativen Poltertherapie (ZiP) von Wolfgang G. Braun. Dazu wurden die folgenden Forschungsfragen gestellt: 1.) Inwiefern berücksichtigen bestehende Polterprogramme die Kommunikationsorganisation, 2.) wie kann eine Förderspielsammlung aufgebaut werden, damit diese entwicklungs- und störungsspezifisch sowie nachvollziehbar ist und 3.) wie schätzen Fachpersonen die Entwicklungs- und Störungsbildspezifität sowie die Nachvollziehbarkeit der erstellten Förderspielsammlung ein? Um die erste Forschungsfrage zu beantworten wurde eine Literaturrecherche durchgeführt. Zur Beantwortung der zweiten Fragestellung wurde die Praxisforschung und insbesondere der Ansatz «Design-Based Research» angewendet. Die dritte Frage wurde mit der Methode der Evaluationsforschung beantwortet. Das Ergebnis der Arbeit ist eine für die logopädische Arbeit Sinn machende Förderspielesammlung. Die 23 entstandenen Förderspiele eignen sich für die Therapie unterschiedlicher Bereiche der Kommunikationsorganisation bei polternden Kindern im Alter von 5-9 Jahren und 9-12 Jahren.

description: Diese Arbeit befasst sich mit der allgemeinen Bedeutung und dem Stellenwert der Kommunikation bei Jungbetroffenen und deren Angehörigen im Frühstadium der Demenz. Besonderen Fokus wird dabei auf die Wohnselbstständigkeit gelegt und wie diese mit gezielter logopädischer Unterstützung längstmöglich erhalten werden kann. Da die Personengruppe der wohnselbstständigen Demenzbetroffenen auch ein wichtiges Arbeitsgebiet der Spitex ist, entsteht die Frage nach der Zusammenarbeit der beiden Professionen. Die Umfrage mit Spitexmitarbeitern zeigt, dass eine Zusammenarbeit beider Professionen durchaus als sinnvoll und praktisch umsetzbar erachtet wird. Aktuell wird die interprofessionelle Zusammenarbeit jedoch kaum praktiziert (Kanton Zürich). Ergänzend werden durch drei qualitative Leitfadeninterviews mit Jungbetroffenen deren persönliche Haltung, Wünsche und Bedürfnisse zu kommunikativen Angeboten ermittelt.

description: We discuss the method to compute the integrals which appear in the retarded potential term for a real-time simulation based on QED (Quantum Electrodynamics). We show that the oscillatory integrals over the infinite interval involved in them can be efficiently performed by the method developed by Ooura and Mori based on the double exponential (DE) formula.
