description: Medical data analysis often combines both imaging and tabular data processing using machine learning algorithms. While previous studies have investigated the impact of attention mechanisms on deep learning models, few have explored integrating attention modules and tabular data. In this paper, we introduce TabAttention, a novel module that enhances the performance of Convolutional Neural Networks (CNNs) with an attention mechanism that is trained conditionally on tabular data. Specifically, we extend the Convolutional Block Attention Module to 3D by adding a Temporal Attention Module that uses multi-head self-attention to learn attention maps. Furthermore, we enhance all attention modules by integrating tabular data embeddings. Our approach is demonstrated on the fetal birth weight (FBW) estimation task, using 92 fetal abdominal ultrasound video scans and fetal biometry measurements. Our results indicate that TabAttention outperforms clinicians and existing methods that rely on tabular and/or imaging data for FBW prediction. This novel approach has the potential to improve computer-aided diagnosis in various clinical workflows where imaging and tabular data are combined. We provide a source code for integrating TabAttention in CNNs at https://github.com/SanoScience/Tab-Attention.

description: We study spectra of surface states in 2D topological insulators (TIs) based on HgTe/(Hg,Cd)Te quantum wells and 3D Bi$_2$Se$_3$-type compounds by constructing a class of feasible time-reversal invariant boundary conditions (BCs) for an effective ${\bf k}{\bf p}$-Hamiltonian and a tight-binding model of the topological insulators. The BCs contain some phenomenological parameters which implicitly depend on both bulk Hamiltonian parameters and crystal potential behavior near the crystal surface. Space symmetry reduces the number of the boundary parameters to four real parameters in the 2D case and three in the 3D case. We found that the boundary parameters may strongly affect not only an energy spectrum but even the very existence of these states inside the bulk gap near the Brillouin zone center. Nevertheless, we reveal in frames of the tight-binding model that when surface states do not exist in the bulk gap in the Brillouin zone center they cross the gap in other points of the Brillouin zone in agreement with the bulk-boundary correspondence.

description: We present the results of muon-spin relaxation measurements of spin excitations in the one-dimensional quantum Heisenberg antiferromagnet Cu(pyz)(NO$_{3}$)$_{2}$. Using density-functional theory we propose muon sites and assess the degree of perturbation the muon probe causes on the system. We identify a site involving the muon forming a hydroxyl-type bond with an oxygen on the nitrate group that is sensitive to the characteristic spin dynamics of the system. Our measurements of the spin dynamics show that in the temperature range $T_{\mathrm{N}}J$ and that in the related two-dimensional system Cu(pyz)$_2$(ClO$_4$)$_{2}$.

description: We show that the flocking transition in the Vicsek model is best understood as a liquid-gas transition, rather than an order-disorder one. The full phase separation observed in flocking models with Z2 rotational symmetry is, however, replaced by a microphase separation leading to a smectic arrangement of traveling ordered bands. Remarkably, continuous deterministic descriptions do not account for this difference, which is only recovered at the fluctuating hydrodynamics level. Scalar and vectorial order parameters indeed produce different types of number fluctuations, which we show to be essential in selecting the inhomogeneous patterns. This highlights an unexpected role of fluctuations in the selection of flock shapes.

description: Despite considerable progress, the advancement of Panoptic Narrative Grounding (PNG) remains hindered by costly annotations. In this paper, we introduce a novel Semi-Supervised Panoptic Narrative Grounding (SS-PNG) learning scheme, capitalizing on a smaller set of labeled image-text pairs and a larger set of unlabeled pairs to achieve competitive performance. Unlike visual segmentation tasks, PNG involves one pixel belonging to multiple open-ended nouns. As a result, existing multi-class based semi-supervised segmentation frameworks cannot be directly applied to this task. To address this challenge, we first develop a novel SS-PNG Network (SS-PNG-NW) tailored to the SS-PNG setting. We thoroughly investigate strategies such as Burn-In and data augmentation to determine the optimal generic configuration for the SS-PNG-NW. Additionally, to tackle the issue of imbalanced pseudo-label quality, we propose a Quality-Based Loss Adjustment (QLA) approach to adjust the semi-supervised objective, resulting in an enhanced SS-PNG-NW+. Employing our proposed QLA, we improve BCE Loss and Dice loss at pixel and mask levels, respectively. We conduct extensive experiments on PNG datasets, with our SS-PNG-NW+ demonstrating promising results comparable to fully-supervised models across all data ratios. Remarkably, our SS-PNG-NW+ outperforms fully-supervised models with only 30% and 50% supervision data, exceeding their performance by 0.8% and 1.1% respectively. This highlights the effectiveness of our proposed SS-PNG-NW+ in overcoming the challenges posed by limited annotations and enhancing the applicability of PNG tasks.

description: Reducing maternal mortality is a priority for UN Sustainable Development Goals. Safe childbirth is key. Caesarean Section (CS) is an integral part of the World Health Organization’s (WHO) comprehensive emergency obstetric care package to prevent maternal and perinatal deaths, and is a key indicator of healthcare system performance. Life-saving CS is associated with high maternal and perinatal deaths in low-and-middle income settings (LMIC), which have resulted in major concerns about the safety of CS and the appropriateness in LMICs. Both high and low CS rates adversely affect maternal and perinatal outcomes. Although WHO does not specify an optimal CS rate, there is growing concern that the global CS rates are too high. In order to propose and implement effective measures to amend CS rates, it is essential to identify what groups of women are undergoing CS and investigate the reasons in different settings. This requires a classification system that can monitor and compare rates in a standardized, reliable and action-oriented manner.

description: The future Belle II experiment will employ a computer-farm based data reduction system for the readout of its innermost detector, a DEPFET-technology based silicon detector with pixel readout. A large fraction of the background hits can be rejected by defining a set of Regions Of Interest (ROI) on the pixel detector sensors and then recording just the data from the pixels inside the ROI. The ROIs are defined on an event by event basis by extrapolating back onto the PXD the charged tracks detected in the outer trackers (a 4 layer double-sided silicon strip detector surrounded by a wire chamber). The tracks are reconstructed in real time on the High Level Trigger (HLT). The pixel detector is then read out based on the ROI information. A demonstrator of this architecture was under beam test earlier this year in DESY (Hamburg, Germany). The demonstrator was operated in an electron beam whose momentum was in the 2-6 GeV/c range with a typical trigger rate of a few kHz in a magnetic field of strength up to 1 T. The demonstrator consists of one pixel sensor and 4 silicon strip sensors arranged in a 5 layers configuration mimicking the Belle II vertex detector. The detector readout was a scaled down version of the full Belle II DAQ + HLT chain. The demonstrator was used to detect the particles, reconstruct in real time the trajectories, identify the ROIs on the PXD plane and record the PXD data within. We describe the requirements and the architecture of the final system together with the results obtained with the demonstrator.

description: Generating and tailoring photocurrent in topological materials has immense importance in fundamental studies and the technological front. Present work introduces a universal method to generate ultrafast photocurrent in {\it both} inversion-symmetric and inversion-broken Weyl semimetals with degenerate Weyl nodes at the Fermi level. Our approach harnesses the asymmetric electronic population in the conduction band induced by an intense {\it single-color} circularly polarized laser pulse. It has been found that the induced photocurrent can be tailored by manipulating helicity and ellipticity of the employed laser. Moreover, our approach generates photocurrent in realistic situations when the Weyl nodes are positioned at different energies and have finite tilt along a certain direction. Present work adds a new dimension on practical applications of Weyl semimetals for optoelectronics and photonics-based quantum technologies.

description: Diese Masterarbeit fragt nach dem Potential einer „emanzipatorischen Soziologie“ (Wright 2017) für Tiere in der gegenwärtigen deutschsprachigen Forschungslandschaft. Dazu wurden problemzentrierte Interviews mit sieben Personen durchgeführt, die sich bereits mit Tieren beziehungsweise gesellschaftlichen Mensch-Tier-Verhältnissen aus sozialwissenschaftlicher Perspektive beschäftigt haben. Ausgangspunkt für die empirischen Erhebung war die Frage, wie die Interviewten das „soziale Feld“ (Bourdieu und Wacquant 1996) der Soziologie wahrnehmen und wie sie dies in ihrem professionelles Handeln beeinflusst (hat). Ein zentraler Zugang stellte die von Frickel und Gross 2005 publizierte Theorie über „Scientific-Intellectual-Movements“ dar. Dieser ermöglicht eine Einordnung von Situationen und Strategien, die das Aufkommen und den Erfolg einer akademischen Bewegung wahrscheinlicher machen. Die Erzählungen der Interviewten bildeten die Grundlage um eine Einsicht in die sozialen Bedingungen von wissenschaftlicher Erkenntnisproduktion im betreffenden Forschungsbereich in Erfahrung zu bringen. Die Analyse der von ihnen beschriebenen Spannungsverhältnisse und Einflussfaktoren soll zum Verständnis gegenüber der aktuellen Formierung, Beteiligung und Richtung des Diskurses um gesellschaftliche Mensch-Tier-Verhältnisse beitragen.

description: We consider the problem of estimating parameters in large-scale weakly nonlinear inverse problems for which the underlying governing equations is a linear, time-dependent, parabolic partial differential equation. A major challenge in solving these inverse problems using Newton-type methods is the computational cost associated with solving the forward problem and with repeated construction of the Jacobian, which represents the sensitivity of the measurements to the unknown parameters. Forming the Jacobian can be prohibitively expensive because it requires repeated solutions of the forward and adjoint time-dependent parabolic partial differential equations corresponding to multiple sources and receivers. We propose an efficient method based on a Laplace transform-based exponential time integrator combined with a flexible Krylov subspace approach to solve the resulting shifted systems of equations efficiently. Our proposed solver speeds up the computation of the forward and adjoint problems, thus yielding significant speedup in total inversion time. We consider an application from Transient Hydraulic Tomography (THT), which is an imaging technique to estimate hydraulic parameters related to the subsurface from pressure measurements obtained by a series of pumping tests. The algorithms discussed are applied to a synthetic example taken from THT to demonstrate the resulting computational gains of this proposed method.

description: Die sozialwissenschaftliche Forschung versteht die Verwitwung als kritisches Lebensereignis mit potenziell weitreichenden sozialen Folgen. Der Partner*innenverlust tritt dabei überwiegend im höheren Alter auf, weshalb mit dem steigenden Anteil älterer Personen im hohen Alter die Betrachtung des Übergangs in die Verwitwung und der damit verbundenen Auswirkungen auf das Leben im Alter an Bedeutung gewinnt. Die vorliegende Arbeit betrachtet daher Implikationen der Verwitwung auf das Einsamkeitsempfinden und die Möglichkeiten der sozialen Teilhabe im Alter. Darüber hinaus stehen (potenzielle) Veränderungen in den Handlungsspielräumen der Personen im Vordergrund. Die Datenbasis stellen hierfür neun leitfadengestützte, problemzentrierte Interviews mit Personen im Alter ab 75 Jahren dar, welche aus dem an der Universität Wien angesiedelten GENPATH Projekt entstammen. Durch eine thematische Analyse der qualitativen Sekundärdaten lässt sich zunächst die Relevanz der sozialen Beziehungen von Verwitweten in Hinblick auf gegenseitige Hilfe- und Unterstützungsleistungen unterstreichen. Im Weiteren zeigen sich unterschiedliche Ausprägungen und Formen der Einsamkeit, die mit dem Lebensereignis in Verbindung gebracht werden können. Zuletzt lassen sich eine Reihe an Handlungsgewinnen und -verlusten nach der Verwitwung identifizieren, welche sich in Veränderungen der persönlichen Handlungsspielräume ausdrücken und die Lebenslage im Alter kennzeichnen.
description: The social sciences view the loss of a romantic partner as a critical life transition. Due to the commonness of widowhood in late life and with the demographic change in our society, bereavement in old age increases in significance for empirical research. The present thesis therefore explores the impacts of the transition into widowhood in relation to social participation, loneliness and opportunities for action in late life. The data base exists of nine problem-centered interviews with persons aged 75 and older, originating from the GENPATH project of University of Vienna. A thematic analysis of the qualitative secondary data first illustrates the relevance of older widow’s and widower’s relationships to family, friends and neighbors, especially regarding reciprocal forms of support within the network. Next, as a consequence of the transition into widowhood, loneliness becomes evident for part of the sample. Finally, the results reveal a range of action-related wins and losses, that influence the widow’s and widower’s scope of action and opportunities in later life.

description: Quantum gravity is often expected to solve both the singularity problem and the information-loss problem of black holes. This article presents an example from loop quantum gravity in which the singularity problem is solved in such a way that the information-loss problem is made worse. Quantum effects in this scenario, in contrast to previous non-singular models, do not eliminate the event horizon and introduce a new Cauchy horizon where determinism breaks down. Although infinities are avoided, for all practical purposes the core of the black hole plays the role of a naked singularity. Recent developments in loop quantum gravity indicate that this aggravated information loss problem is likely to be the generic outcome, putting strong conceptual pressure on the theory.

description: Fitness-Lover, insbesondere Fitness-Influencer, posten ihren trainierten Körper, ihre Workouts und ihr gesundes Essen auf Social Media mit dem Hashtag #fitspiration oder #fitspo. Fitspiration ist ein Trend, der Menschen dazu anregen soll, einen gesunden und aktiven Lebensstil zu führen. Die Forschung zeigt unterschiedliche Ergebnisse zu dieser Thematik. Ziel dieser Arbeit ist es, wir Wirkung von Fitspiration-Bildern auf Körper(un)zufriedenheit, Stimmung und Markenwahrnehmung in sozialen Medien zu untersuchen. Da sich die Forschung bisher vor allem auf Frauen konzentriert hat, soll diese Studie einen Beitrag zu diesem Phänomen in Bezug auf Männern leisten. Dazu wurde eine experimentelle Studie mit in Österreich lebenden Männern sowie Personen, die sich als Männer identifizieren bzw. sich zugehörig fühlen, die zwischen 18 und 29 Jahre alt sind, durchgeführt werden. Das 2 (Fitspiration vs. Kein Fitspiration) X 2 (Marke vs. Keine Marke) Studiendesign hat die folgenden vier Bedingungen, bei denen Männer zufällig einer zugeordnet wurden: Gruppe 1 erhält Bilder von trainierten Männern (Fitspiration), die die Sportbekleidung von Nike tragen (Marke), Gruppe 2 bekommt Bilder von durchschnittlich gebauten Männern (kein Fitspiration), die auch Nike tragen (Marke). In Gruppe 3 erhalten die Personen Bilder von trainierten Männern (Fitspiration), aber es wird keine Sportmarke zu sehen sein (keine Marke), und Gruppe 4 bekommt Bilder von durchschnittlich gebauten Männern (kein Fitspiration) auch ohne Einbettung von Nike (keine Marke). Moderator ist der BMI der Probanden. Die Ergebnisse zeigten bei keinen hergeleiteten Hypothesen eine signifikante Auswirkung. Daher könne keine Aussagen gemacht werden. In weiteren Untersuchungen sollten die Limitationen dieser Studie aufgezeigt werden wie, dass eine größere Stichprobe wichtig ist und auch, dass der Stimulus stärker sein sollte, um auch tatsächlich einen Effekt hervorrufen zu können.

description: The equilibrium density of fluids under nanoconfinement can differ substantially from their bulk density. Using a mean-field approach to describe the energetic landscape near the carbon nanotube (CNT) wall, we obtain analytical results describing the lengthscales associated with the layering observed at the fluid-CNT interface. When combined with molecular simulation results for the fluid density in the layered region, this approach allows us to derive a closed-form prediction for the overall equilibrium fluid density as a function of the CNT radius that is in excellent agreement with molecular dynamics simulations. We also show how aspects of this theory can be extended to describe water confined within CNTs and find good agreement with results from the literature.

description: General lowest order perturbations to hermitian squared mass matrices of leptons are considered away from the tribimaximal (TBM) limit in which a weak flavor basis with mass diagonal charged leptons is chosen. The three measurable TBM deviants are expressed linearly in terms of perturbation induced dimensionless coefficients appearing in the charged lepton and neutrino flavor eigenstates. With unnatural cancellations assumed to be absent and the charged lepton perturbation contributions to their flavor eigenstates argued to be small, we analytically derive the following result. Within lowest order perturbations, a deviation from maximal atmospheric neutrino mixing and the amount of CP violation in neutrino oscillations cannot both be large (i.e. $12$-$17 \% $), posing the challenge of verification to forthcoming experiments at the intensity frontier.

title: Die romanischen Anteile der Klosterkirche Millstatt, mit besonderem Augenmerk auf den oberitalienischen Einfluss am Westportal
Creators: name: Hanny, Sabrina
Year: 2022

description: Die vorliegende Arbeit befasst sich mit der ehemaligen Stiftskirche, heute Pfarrkirche St. Salvator und Allerheiligen von Millstatt in Kärnten. Es handelt sich hierbei um eine ursprünglich romanische, dreischiffige Pfeilerbasilika mit wenig überhöhtem Mittelschiff, welche zum Großteil noch in ihrer ursprünglichen Gestalt erhalten ist. Durch die Neuauslage der Domitianslegende, wird davon ausgegangen, dass die Stiftskirche vermutlich zwischen 1120/25 durch einen Großbrand vernichtet wurde und unter Abt Otto I. neu aufgebaut wurde. Oftmals wird als Blütezeit der Kirche, jene unter der Regierungszeit von Abt Heinrich II. 1166-1177/78 genannt. Dieser Abt hat sich auch auf dem hier zu behandelnden Westportalstympanon inschriftlich verewigen lassen. Jener Abt hielt stets Ausschau nach äußerst qualifizierten Bauleuten. Dies Bezeugt vor allem die Qualität des figuralen Schmucks an den beiden Portalen als auch im Kreuzgang. In der heutigen Forschung gibt es kaum oder wenige direkte Vergleichsbeispiele, woher die Formen des Millstätter Westportals stammen könnten. Es wird zwar immer wieder ein Vergleich auf die normannischen Einflüsse am Westportal hergestellt, aber auch diese werden selten Vertiefend behandelt. Man kann schon von einer Seltenheit sprechen, wenn man nach anderen Einflüssen in der Literatur sucht und hierzu fündig wird. Aus diesem Grund bildete diese Ausgangssituation den Grundstein für weitere Betrachtungen. Im Allgemeinen lässt sich also sagen, dass die gesamte Vorhallenplastik der Millstätter Stiftskirche eines der beeindruckensten Zeugnisse der österreichischen, romanischen Bildhauerei ist. Die besondere Portalform lässt sich am ehesten den romanischen Portalen in Bayern, als auch der Lombardei vergleichen.

description: We show that if $T$ is any of four semigroups of two elements that are not groups, there exists a finite dimensional associative $T$-graded algebra over a field of characteristic $0$ such that the codimensions of its graded polynomial identities have a non-integer exponent of growth. In particular, we provide an example of a finite dimensional graded-simple semigroup graded algebra over an algebraically closed field of characteristic $0$ with a non-integer graded PI-exponent, which is strictly less than the dimension of the algebra. However, if $T$ is a left or right zero band and the $T$-graded algebra is unital, or $T$ is a cancellative semigroup, then the $T$-graded algebra satisfies the graded analog of Amitsur's conjecture, i.e. there exists an integer graded PI-exponent. Moreover, in the first case it turns out that the ordinary and the graded PI-exponents coincide. In addition, we consider related problems on the structure of semigroup graded algebras.

description: We study electric and magnetic monopoles in static, spherically symmetric and constant curvature geometries in the context of the inverse electrodynamics model. We prove that this U(1) invariant Lagrangian density is able to support the standard metric of a Reissner-Nordstrom Black Hole, but with more complex thermodynamical properties than in the standard case. By employing the Euclidean Action approach we perform a complete analysis of its phase space depending on the sign and singularities of the heat capacity and the Helmholtz free energy.

description: We present a theoretical analysis of mid-infrared radiative recombination in InAs/GaSb superlattices (SLs). We employ a semi-analytical plane wave expansion method in conjunction with an 8-band $\mathbf{k} \cdot \mathbf{p}$ Hamiltonian to compute the SL electronic structure, paying careful attention to the identification and mitigation of spurious solutions. The calculated SL eigenstates are used directly to compute spontaneous emission spectra and the radiative recombination coefficient $B$. We elucidate the origin of the relatively large $B$ coefficients in InAs/GaSb SLs which, despite the presence of spatially indirect (type-II-like) carrier confinement, are close to that of bulk InAs and compare favourably to those calculated for mid-infrared type-I pseudomorphic and metamorphic quantum well structures having comparable emission wavelengths. Our analysis explicitly quantifies the roles played by carrier localisation (specifically, partial delocalisation of bound electron states) and miniband formation (specifically, miniband occupation and optical selection rules) in determining the magnitude of $B$ and its temperature dependence. We perform a high-throughput optimisation of the room temperature $B$ coefficient in InAs/GaSb SLs across the 3.5 -- 7 $μ$m wavelength range, quantifying the dependence of $B$ on the relative thickness of the electron-confining InAs and hole-confining GaSb layers. This analysis provides guidance for the growth of optimised SLs for mid-infrared light emitters. Our results, combined with the expected low non-radiative Auger recombination rates in structures having spatially indirect electron and hole confinement, corroborate recently observed high output power in prototype InAs/GaSb SL inter-band cascade light-emitting diodes.

description: We study the far-from-equilibrium dynamics of a (2+1)-dimensional superfluid at finite temperature and chemical potential using its holographic description in terms of a gravitational system in 3+1 dimensions. Starting from various initial conditions corresponding to ensembles of vortex defects we numerically evolve the system to long times. At intermediate times the system exhibits Kolmogorov scaling the emergence of which depends on the choice of initial conditions. We further observe a universal late-time regime in which the occupation spectrum and different length scales of the superfluid exhibit scaling behaviour. We study these scaling laws in view of superfluid turbulence and interpret the universal late-time regime as a non-thermal fixed point of the dynamical evolution. In the holographic superfluid the non-thermal fixed point can be understood as a stationary point of the classical equations of motion of the dual gravitational description.

description: Fermionic atoms in optical lattices have served as a compelling model system to study and emulate the physics of strongly-correlated matter. Driven by the advances of high-resolution microscopy, the recent focus of research has been on two-dimensional systems in which several quantum phases, such as anti-ferromagnetic Mott insulators for repulsive interactions and charge-density waves for attractive interactions have been observed. However, the aspired emulations of real materials, such as bilayer graphene, have to take into account that their lattice structure composes of coupled layers and therefore is not strictly two-dimensional. In this work, we realize a bilayer Fermi-Hubbard model using ultracold atoms in an optical lattice and demonstrate that the interlayer coupling controls a crossover between a planar anti-ferromagnetically ordered Mott insulator and a band insulator of spin-singlets along the bonds between the layers. Our work will enable the exploration of further fascinating properties of coupled-layer Hubbard models, such as theoretically predicted superconducting pairing mechanisms.

description: Very few AdS_6 x M_4 supersymmetric solutions are known: one in massive IIA, and two IIB solutions dual to it. The IIA solution is known to be unique; in this paper, we use the pure spinor approach to give a classification for IIB supergravity. We reduce the problem to two PDEs on a two-dimensional space Sigma. M_4 is then a fibration of S^2 over Sigma; the metric and fluxes are completely determined in terms of the solution to the PDEs. The results seem likely to accommodate near-horizon limits of (p,q)-fivebrane webs studied in the literature as a source of CFT_5's. We also show that there are no AdS_6 solutions in eleven-dimensional supergravity.

Speeding up differentiable programming with a Computer Algebra System
Creators: name: De Boer, Remco
Publisher: name: Zenodo
Year: 2022

description: In the ideal world, we describe our models with recognizable mathematical expressions and directly fit those models to large data samples with high performance. It turns out that this can be done by formulating our models with SymPy (a Computer Algebra System) and using its symbolic expression trees as template to computational back-ends like JAX and TensorFlow. The CAS can in fact further simplify the expression tree, which results in speed-ups in the numerical back-end.
 In this talk, we have a look at amplitude analysis as a case study and use the Python libraries of the ComPWA project to formulate and fit large expressions to unbinned, multidimensional data sets.

description: Storing, transmitting, and manipulating information using the electron spin resides at the heart of spintronics. Fundamental for future spintronics applications is the ability to control spin currents in solid state systems. Among the different platforms proposed so far, semiconductors with strong spin-orbit interaction are especially attractive as they promise fast and scalable spin control with all-electrical protocols. Here we demonstrate both the generation and measurement of pure spin currents in semiconductor nanostructures. Generation is purely electrical and mediated by the spin dynamics in materials with a strong spin-orbit field. Measurement is accomplished using a spin-to-charge conversion technique, based on the magnetic field symmetry of easily measurable electrical quantities. Calibrating the spin-to-charge conversion via the conductance of a quantum point contact, we quantitatively measure the mesoscopic spin Hall effect in a multiterminal GaAs dot. We report spin currents of 174 pA, corresponding to a spin Hall angle of 34%.

description: Grading, immunohistochemistry and c-kit mutation status are criteria for assessing the prognosis and therapeutic options of canine cutaneous mast cell tumours (MCTs). As a subset, canine digital MCTs have rarely been explored in this context. Therefore, in this retrospective study, 68 paraffin-embedded canine digital MCTs were analysed, and histological grading was assessed according to Patnaik and Kiupel. The immunohistochemical markers KIT and Ki67 were used, as well as polymerase chain reaction (PCR) for mutational screening in c-kit exons 8, 9, 11 and 14. Patnaik grading resulted in 22.1% grade I, 67.6% grade II and 10.3% grade III tumours. Some 86.8% of the digital MCTs were Kiupel low-grade. Aberrant KIT staining patterns II and III were found in 58.8%, and a count of more than 23 Ki67-positive cells in 52.3% of the cases. Both parameters were significantly associated with an internal tandem duplication (ITD) in c-kit exon 11 (12.7%). French Bulldogs, which tend to form well-differentiated cutaneous MCTs, had a higher proportion of digital high-grade MCTs and ITD in c-kit exon 11 compared with mongrels. Due to its retrospective nature, this study did not allow for an analysis of survival data. Nevertheless, it may contribute to the targeted characterisation of digital MCTs.

description: Computer models of humans are ubiquitous throughout computer animation and computer vision. However, these models rarely represent the dynamics of human motion, as this requires adding a complex layer that solves body motion in response to external interactions and according to the laws of physics. FLSH is a library that facilitates this task for researchers and developers who are not interested in the nuisances of physics simulation, but want to easily integrate dynamic humans in their applications. FLSH provides easy access to three flavors of body physics, with different features and computational complexity: skeletal dynamics, full soft-tissue dynamics, and reduced-order modeling of soft-tissue dynamics. In all three cases, the simulation models are built on top of the pseudo-standard SMPL parametric body model.
