description: Nanophotonic chiral antennas exhibit orders of magnitude higher circular dichroism (CD) compared to molecular systems. Merging magnetism and structural chirality at the nanometric level allows for the efficient magnetic control of the dichroic response, bringing exciting new prospects to active nanophotonic devices and magnetochirality. Here we devise macroscale enantiomeric magnetophotonic metasurfaces of plasmon and ferromagnetic spiral antennas. Mixed 2D- and 3D- chiral nanoantennas induce large CD response, where we identify reciprocal and non-reciprocal contributions. The simultaneous chiroptical and magneto-optical response in a wide spectral range with these metasurfaces delivers an attractive platform for the study of magnetochirality at the nanoscale. Exploring further this type of magnetophotonic metasurfaces allows the realization of high-sensitivity chiral sensors and prompts the design of novel macroscopic optical devices operating with polarized light.

description: In this paper, we propose a general architecture for designing language servers for hybrid modeling languages, that is, modeling languages that contain both textual and graphical representations. The architecture consists of a textual language server, a graphical language server, and a client that communicates with the two servers. The servers are implemented using the Language Server Protocol (LSP) and the Graphical Language Server Protocol (GLSP) and are based on a shared abstract syntax of the hybrid language. This means that only static resources need to be common between the graphical and textual language servers. The servers' separation allows each to be developed and maintained independently, while also enabling forward-compatibility with their respective dependencies. We describe a prototype implementation of our architecture in the form of a hybrid editor for the UML-RT language. The evaluation of the architecture via this prototype gives us useful insight into further generalization of the architecture and the way it is used. We then sketch a suitable extension of the architecture to enable support for multiple diagram types and, thus, multiple graphical views.

description: We develop a new nonlinear stability method, the Energy-Enstrophy (EZ) method, that is specialized to two-dimensional hydrodynamics; the method is applied to a beta-plane flow driven by a sinusoidal body force, and retarded by drag with damping time-scale mu^{-1}. The standard energy method (Fukuta and Murakami, J. Phys. Soc. Japan, 64, 1995, pp 3725) shows that the laminar solution is monotonically and globally stable in a certain portion of the (mu,beta)-parameter space. The EZ method proves nonlinear stability in a larger portion of the (mu,beta)-parameter space. And by penalizing high wavenumbers, the EZ method identifies a most strongly amplifying disturbance that is more physically realistic than that delivered by the energy method. Linear instability calculations are used to determine the region of the (mu,beta)-parameter space where the flow is unstable to infinitesimal perturbations. There is only a small gap between the linearly unstable region and the nonlinearly stable region, and full numerical solutions show only small transient amplification in that gap.

description: The use of magneto-optical techniques to tune the plasmonic response of nanostructures is a hot topic in active plasmonics, with fascinating implications for several plasmon-based applications and devices. For this emerging field, called magnetoplasmonics, plasmonic nanomaterials with strong optical response to magnetic field are desired, which is generally challenging to achieve with pure noble metals. To overcome this issue, several efforts have been carried out to design and tailor the magneto-optical response of metal nanostructures, mainly by combining plasmonic and magnetic materials in a single nanostructure. In this tutorial we focus our attention on magnetoplasmonic effects in purely plasmonic nanostructures, as they are a valuable model system allowing for an easier rationalization of magnetoplasmonic effects. The most common magneto-optical experimental methods employed to measure these effects are introduced, followed by a review of the major experimental observations that are discussed within the framework of an analytical model developed for the rationalization of magnetoplasmonic effects. Different materials are discussed, from noble metals to novel plasmonic materials, such as heavily doped semiconductors.

description: Congenital heart disease (CHD) is the most common congenital abnormality associated with birth defects in the United States. Despite training efforts and substantial advancement in ultrasound technology over the past years, CHD remains an abnormality that is frequently missed during prenatal ultrasonography. Therefore, computer-aided detection of CHD can play a critical role in prenatal care by improving screening and diagnosis. Since many CHDs involve structural abnormalities, automatic segmentation of anatomical structures is an important step in the analysis of fetal echocardiograms. While existing methods mainly focus on the four-chamber view with a small number of structures, here we present a more comprehensive deep learning segmentation framework covering 14 anatomical structures in both three-vessel trachea and four-chamber views. Specifically, our framework enhances the V-Net with spatial dropout, group normalization, and deep supervision to train a segmentation model that can be applied on both views regardless of abnormalities. By identifying the pitfall of using the Dice loss when some labels are unavailable in some images, this framework integrates information from multiple views and is robust to missing structures due to anatomical anomalies, achieving an average Dice score of 79%.

description: In the context of a gravity's rainbow, the asymptotic quasinormal modes of the scalar perturbation in the quantum modified Schwarzschild black holes are investigated. By using the monodromy method, we calculated and obtained the asymptotic quasinormal frequencies, which are dominated not only by the mass parameter of the spacetime, but also by the energy functions from the modified dispersion relations. However, the real parts of the asymptotic quasinormal modes is still $T_H\ln 3$, which is consistent with Hod's conjecture. In addition, for the quantum corrected black hole, the area spacing is calculated and the result is independent of the energy functions, in spite of the area itself is energy dependence. And that, by relating the area spectrum to loop quantum gravity, the Barbero-Immirzi parameter is given and it remains the same as from the usual black hole.

description: We present the results from the multi-wavelength monitoring observations of the Narrow-Line Seyfert 1 galaxy Mrk 335 with AstroSat. We analysed both the X-ray (SXT & LAXPC) and UV (UVIT) data of the source at two epochs, separated by ~18 days. The source was in a low flux state during the observations, and the X-ray spectra were found to be harder than usual. The presence of soft X-ray excess was identified in the observations, and the broadband X-ray continuum was modelled with power-law and blackbody (modified by intrinsic absorption) and a distant neutral reflection component. We did not find any variability in the X-ray spectral shape or the flux over this period. However, the UV flux is found to be variable between the observations. The obtained results from the X-ray analysis point to a scenario where the primary emission is suppressed and the component due to distant reflection dominates the observed spectrum.

description: Neonatal sepsis is a condition that poses a significant threat to new-borns in neonatal intensive care units (NICUs), and its early detection is a critical challenge due to the nonspecific symptoms associated with it. This thesis presents the design and evaluation of the user interface (UI) of the Digi-NewB system, which was developed to aid in the early diagnosis and management of neonatal sepsis. Utilizing a Human-Centred Design (HCD) approach, the research involved the iterative development of the UI and focused on usability, human factors, and the alignment with clinicians' workflow in NICUs. The research commenced with a comprehensive exploration of existing UIs in physiological monitors and wearable devices used in critical care settings. These chapters highlight the need for balancing innovation with familiarity and acknowledged the constraints of the critical care clinical environment. A significant outcome from this exploration was the realization that wearable technology, although promising, was not yet viable for integration into the Digi-NewB system. Furthermore, an international survey of clinicians informed the design of the UI, by emphasizing the importance of touchscreen interfaces and the preference for non-intrusive alarms. The survey also revealed a gap in formal training associated with existing patient monitors, leading to the development of an elearning platform for the Digi-NewB UI. This training platform was designed to address the need for flexible, comprehensive training methods for critical care clinicians. The thesis also describes the development of the Digi-NewB UI through iterative prototyping and evaluation. The thesis concludes by describing a usability evaluation of the Digi-NewB UI conducted in a high-fidelity simulation setting. This preliminary evaluation of the UI, involving NICU nurses, confirmed the effectiveness of the HCD approach, with the UI being positively received by the participants.

description: Dieser Artikel porträtiert den Germanisten und Schriftsteller Peter Demetz (1922–2024) als transatlantische Schlüsselfigur auf Grundlage seiner Korrespondenzen mit dem Merkur Herausgeber Hans Paeschke. Durch Skizzieren der vielfältigen Bestrebungen von Demetz wird klar, dass es seine professionelle und persönliche Flexibilität und Offenheit waren, die ihm die erfolgreiche transatlantische Transition von Europa in die USA ermöglicht haben. Inmitten der aktuellen geopolitischen Spannungen kann Demetz's kreative und konstruktive Herangehensweise an das akademische und das literarische Arbeiten heute ein Modell sein, transatlantischen Austausch zu gestalten.

Demetz's manifold pursuits show his professional and personal broad-mindedness which has allowed him to successfully master the transatlantic transition from Europe to the US. Sketching Demetz's manifold pursuits, I argue that his professional flexibility and openness allowed him to successfully master the transatlantic transition from Europe to the US. Given rising geopolitical tensions, Demetz's creative and constructive approach to academic and literary work beyond rigid institutional conventions may inspire transatlantic careers and communication today.

description: Membrane and nuclear proteins of poor solubility have been separated by high resolution two-dimensional (2-D) gel electrophoresis. Isoelectric focusing with immobilized pH gradients leads to severe quantitative losses of proteins in the resulting 2-D map, although the resolution is usually high. Protein solubility could be improved by using denaturing solutions containing various detergents and chaotropes. Best results were obtained with a denaturing solution containing urea, thiourea, and detergents (both nonionic and zwitterionic). The usefulness of thiourea-containing denaturing mixtures is shown for microsomal and nuclear proteins as well as for tubulin, a protein highly prone to aggregation.

description: A molecular Mott insulator $κ$-(ET)$_2$B(CN)$_4$ [ET = bis(ethylenedithio)tetrathiafulvalene] with a distorted triangular lattice exhibits a quantum disordered state with gapped spin excitation in the ground state. $^{13}$C nuclear magnetic resonance, magnetization, and magnetic torque measurements reveal that magnetic field suppresses valence bond order and induces long-range magnetic order above a critical field $\sim 8$ T. The nuclear spin-lattice relaxation rate $1/T_1$ shows persistent evolution of antiferromagnetic correlation above the transition temperature, highlighting a quantum spin liquid state with fractional excitations. The field-induced transition as observed in the spin-Peierls phase suggests that the valence bond order transition is driven through renormalized one-dimensionality and spin-lattice coupling.

My research encompasses a sea pen collection of over 400 specimens, enabling me to explore various analyses related to morphology, phylogeny, and species boundaries.
title: The use of the biodesign innovation process to identify an unmet clinical need in heart failure with preserved ejection fraction

Year: 2024

subject: Biodesign innovation
subject: Heart failure

description: Heart failure, also known as congestive heart failure, is a disorder that occurs when the heart cannot pump enough blood to meet the requirements from the body. Heart Failure with Preserved Ejection Fraction (HFpEF) is a classification of heart failure where the left ventricular ejection fraction is greater than or equal to 50%. Half of all heart failure cases are HFpEF with 32 million people living with HFpEF worldwide. HFpEF has a complex aetiology and pathophysiology as well as poor outcomes with a 5-year mortality of up to 75%. While the treatment landscape is constantly evolving, the heterogeneous nature of this population makes standardising treatment with medication extremely difficult in HFpEF patients. There are limited specific drug therapies available for the treatment of HFpEF and no device-based therapy has yet been approved for the management of HFpEF. This thesis outlines how the phases of the Biodesign Process were deployed to identify an unmet clinical need in HFpEF. The three phases of the Biodesign Process are Identify, Invent, and Implement. Through the Identify Phase, 880 need statement were created by the cardiology team. These 880 need statements were narrowed down to the top 3 need statements through detailed validation and research. The HFpEF need was chosen to be the topic of further research due to personal preference. An insight into the relationship between epicardial adipose tissue (EAT) and HFpEF was crucial to the Invent Phase of the Biodesign Process. The insight discovered was that increased EAT is associated with the development, progression, and prognosis of HFpEF. This thesis hypothesises that reducing EAT back to a healthy level in a subset of HFpEF patients will provide an acute and chronic outcome to the symptoms of HFpEF patients. In the Concept Generation stage of the Invent Phase, a brainstorming session was conducted. This session led to the development of Concept 1 and Concept 2. Through further validation with key stakeholders, Concept 1 was chosen to have the best chance of success. Concept 1 involves intravascular access to the chambers of the heart where a high intensity focused ultrasound (HIFU) will be deployed to denature EAT on the other side of the myocardium. A relevant haemodynamic parameter will be monitored to measure the effect of the acute reduction of EAT. The selected concept showed no major failing points in terms of IP, reimbursement, or the regulatory pathway. In conclusion, the Biodesign Process enabled the identification of an unmet clinical need in HFpEF. The Biodesign Process led to the development of a proposed solution direction with no major failing points. HFpEF patients are an underserved population with no approved alternative devices for the treatment of the condition. This solution has the potential to have a significant impact on the lives of HFpEF patients.

description: We imaged the Lynds 723 dark nebula (L723) with the aim of studying the morphology of the Herbig-Haro object HH 223 and other line-emission nebula detected in the region. We obtained deep narrow-band images in the Halpha and [SII] lines and in the continuum nearby Halpha of a field of ~5' of the L723 dark nebula centered on HH 223. The Halpha and [SII] images reveal the detailed morphology of HH 223, unresolved in previous optical images. Both images show a quite complex knotty, wiggling structure embedded in a low-emission nebula. Comparison between the [SII] and Halpha fluxes of the knots are indicative of variations in the excitation conditions through HH 223. In addition, several other faint nebula are detected in Halpha a few arcmin to the SE and to the NW of HH 223, all of them lying projected onto the east-west pair of lobes of the quadrupolar CO outflow. Comparison between the Halpha and the continuum images confirms the HH-like nature of the Vrba object V83, while the Vrba objects V84 and V85 are identified as faint field stars.

description: Microcalcifications are small deposits of calcium that appear in mammograms as bright white specks on the soft tissue background of the breast. Microcalcifications may be a unique indication for Ductal Carcinoma in Situ breast cancer, and therefore their accurate detection is crucial for diagnosis and screening. Manual detection of these tiny calcium residues in mammograms is both time-consuming and error-prone, even for expert radiologists, since these microcalcifications are small and can be easily missed. Existing computerized algorithms for detecting and segmenting microcalcifications tend to suffer from a high false-positive rate, hindering their widespread use. In this paper, we propose an accurate calcification segmentation method using deep learning. We specifically address the challenge of keeping the false positive rate low by suggesting a strategy for focusing the hard pixels in the training phase. Furthermore, our accurate segmentation enables extracting meaningful statistics on clusters of microcalcifications.

The concepts of growth and the cell : students' alternative conceptions and the nature of conceptual change
Creators: name: Luyten, Peter Henri
Publisher: name: University of British Columbia
Year: 2011

description: Learning difficulties resulting from students holding conceptions of scientific concepts which are at variance with those presented in curricular materials have been identified in the literature in a number of areas of science. In this study a number of student learning difficulties related to the concepts of growth and the cell were identified. More specifically, this study was designed to investigate whether alternative conceptions held by students prior to instruction were, in part, responsible for these learning difficulties. The study also investigated whether omissions in instruction contributed to these learning difficulties. Finally, the study examined changes in student conceptions after formal instruction. Through concept analyses of growth and the cell, two semi-structured interview protocols were developed. The Growth Protocol was used to interview students in Grades 3, 5, and 7 and the Cell Protocol was used to interview students in Grade 10. The students in Grades 3 and 10 were interviewed both before and after instruction. The conceptions of the students identified in the transcripts were classified into a number of categories specific to the constituent concepts of growth and the cell. Students at all grade levels were found to hold a wide variety of alternative conceptions regarding the concepts in question. The majority of these alternative conceptions were identified in more than one student and did not reflect current scientific or curricular understandings of growth or the cell. Rather, it seemed that these alternative conceptions reflected student attempts to make sense of concrete experiences with phenomena in their surroundings. After instruction at both the elementary and secondary level, the majority of students did not incorporate most of the scientific concepts as they were presented during instruction. The older students did not hold a conception of cell differentiation nor did the majority of students link the microscopic phenomena of cell division with the macroscopic phenomena of growth in organisms other than humans. The variability of alternative conceptions of mitosis and meiosis after instruction strongly suggested that the students experienced learning difficulties with respect to these concepts. The results of this study imply that in order to effectively move the learner from alternative conceptions to scientific conceptions both curricular and instructional strategies must shift their emphasis from one of presenting only disciplinary knowledge to one of considering also the prior knowledge that the learner brings to the instructional setting.

description: Visual script languages with a node-based interface have commonly been used in the video game industry. We examined the bug database obtained in the development of FINAL FANTASY XV (FFXV), and noticed that several types of bugs were caused by simple mis-descriptions of visual scripts and could therefore be mechanically detected. We propose a method for the automatic verification of visual scripts in order to improve productivity of video game development. Our method can automatically detect those bugs by using symbolic model checking. We show a translation algorithm which can automatically convert a visual script to an input model for NuSMV that is an implementation of symbolic model checking. For a preliminary evaluation, we applied our method to visual scripts used in the production for FFXV. The evaluation results demonstrate that our method can detect bugs of scripts and works well in a reasonable time.

description: We present a 1.4-GHz catalog of 810 radio sources (560 sources in the complete sample) with 1.8" resolution found within a 17' radius in the SSA13 field (RA=13h12m,DEC=42d38'). The radio image from the VLA has an rms noise level of 4.82 microJy/beam at the field center, and Subaru optical images in r-band (6300A) and z-band (9200A) have a three-sigma detection magnitude of 26.1 and 24.9, respectively. 88% of the radio sources are identified with an optical counterpart, and there is significantly more reddening for objects fainter than 24-mag. The radio and optical parameters are tabulated, and source morphologies are displayed by radio contours overlaying optical false-color images. The radio structures show a wealth of complexity and these are classified into a small number of categories. About one-third of the radio sources are larger than 1.2" and their orientation is often similar to that of the associated galaxy or binary-galaxy system. The density of sources in the SSA13 field above 75 microJy is 0.40 per square arcmin, with a slope of -2.43 in the differential counts. The radio spectral index may steepen for sources below 75 microJy. We estimate that at most 40% of the microJansky radio sources are dominated by AGN processes.

description: Planck scale corrections arising from deformed special relativity on Hawking radiation in Parikh and Wilczk's tunneling framework are studied. We calculate the emission rate of massless particles tunneling though the corrected horizon of modified black holes from gravity's rainbow. In the tunneling process, when a particle get across the quantum horizon, the metric fluctuation not only due to the energy conservation but also quantum effects of the space-time are taken into account. Our results show that, the emission rate is related to the changes of the black hole's quantum corrected entropy and consistent with an underlying unitary theory. In the modified black hole, by using black hole thermodynamics, a series of quantum correction terms including a logarithmic term to the Bekenstein-Hawking entropy are obtained. Correspondingly, the Planck scale corrected emission spectrum is obtained and it deviates from the thermal spectrum.

description: Since the first experimental observation of optical Airy beams, various applications ranging from particle and cell micromanipulation to laser micromachining have exploited their non-diffracting and accelerating properties. The later discovery that Airy beams can self-heal after being blocked by an obstacle further proved their robustness to propagate under scattering and disordered environment. Here, we report the generation of Airy beams on an integrated silicon photonic chip and demonstrate that the on-chip 1D Airy beams preserve the same properties as the 2D beams. The 1D meta-optics used to create the Airy beam has the size of only 3 by 16 microns, at least three orders of magnitude smaller than the conventional optic. The on-chip self-healing beams demonstrated here could potentially enable diffraction-free light routing for on-chip optical networks and high-precision micromanipulation of bio-molecules on an integrated photonic chip.
Electrodynamics of superconductors

description: Electrodynamics of superconductors is primarily the electrodynamics of the Meissner state, a state characterized by zero magnetic induction of a superconducting fraction of conduction electrons. Simultaneously, the Meissner state is characterized by zero resistivity and zero entropy of these electrons. The latter means that the temperature of an ensemble of superconducting electrons is zero as well. Understanding properties of the Meissner state provides a key to understand and predict these and other equilibrium and non-equilibrium properties of superconductors, e.g., properties of the intermediate and mixed states, flux quantization, resistanceless transport current, etc. The reader will see that all these properties have a single and very simple origin: quantization of the angular momentum of the conduction electrons combined into Cooper pairs, and that the electrodynamics of superconductors and superconductivity as a whole is a magnificent manifestation of the boundless ingenuity of Nature and of the power of Physics laws.

description: We show that universal rogue wave patterns exist in integrable systems. These rogue patterns comprise fundamental rogue waves arranged in shapes such as triangle, pentagon and heptagon, with a possible lower-order rogue wave at the center. These patterns appear when one of the internal parameters in bilinear expressions of rogue waves gets large. Analytically, these patterns are determined by the root structures of the Yablonskii-Vorob'ev polynomial hierarchy through a linear transformation. Thus, the induced rogue patterns in the space-time plane are simply the root structures of Yablonskii-Vorob'ev polynomials under actions such as dilation, rotation, stretch, shear and translation. As examples, these universal rogue patterns are explicitly determined and graphically illustrated for the generalized derivative nonlinear Schrödinger equations, the Boussinesq equation, and the Manakov system. Similarities and differences between these rogue patterns and those reported earlier in the nonlinear Schrödinger equation are discussed.

description: Different types of observations, together with consistent and physical modelizations, suggest as realistic the hypothesis of enrichement of galactic nuclei by mean of massive globular clusters orbitally decayed and merged in the inner regions of early type galaxies. In this context, the scenario of globular cluster mergers and subsequent formation of a dense Super Star Cluster in the center of a triaxial galaxy is presented and discussed, together with its astrophysical implications, including that of massive black hole feeding and accretion in the center of a triaxial galaxy.

description: The Bhatnagar-Gross-Krook (BGK) single-relaxation-time collision model for the Boltzmann equation serves as the foundation of the lattice BGK (LBGK) method developed in recent years. The description of the collision as a uniform relaxation process of the distribution function towards its equilibrium is, in many scenarios, simplistic. Based on a previous series of papers, we present a collision model formulated as independent relaxations of the irreducible components of the Hermit coefficients in the reference frame moving with the fluid. These components, corresponding to the irreducible representation of the rotation group, are the minimum tensor components that can be separately relaxed without violating rotation symmetry. For the 2nd, 3rd and 4th moments respectively, two, two and three independent relaxation rates can exist, giving rise to the shear and bulk viscosity, thermal diffusivity and some high-order relaxation process not explicitly manifested in the Navier-Stokes-Fourier equations. Using the binomial transform, the Hermite coefficients are evaluated in the absolute frame to avoid the numerical dissipation introduced by interpolation. Extensive numerical verification is also provided.

description: Precision measurements of a collective mode in superfluid 3He B are sensitive to quasiparticle and f wave pairing interactions. Measurements were performed at various pressures using interference of transverse sound in an acoustic cavity. We fit the measured collective mode frequencies, which depend on the strength of f wave pairing and the Fermi liquid parameter F2s, to theoretical predictions and discuss what implications these values have for observing new order parameter collective modes.

description: Aims. The main goal of the present study is to determine the fractional SiO abundance in high-mass star-forming cores, and to investigate its dependence on the physical conditions. In this way we wish to provide constraints on the chemistry models concerning the formation of SiO in the gas phase or via grain mantle evaporation. The work addresses also CH3CCH chemistry as the kinetic temperature is determined using this molecule. Methods. We estimate the physical conditions of 15 high-mass star-forming cores and derive the fractional SiO and CH3CCH abundances in them by using spectral line and dust continuum observations with the SEST. Results. The kinetic temperatures as derived from CH3CCH range from 25 to 39 K. The SiO emission regions are extended and typically half of the integrated line emission comes from the velocity range traced out by CH3CCH emission. The upper limit of SiO abundance in this 'quiescent' gas component is ~10^-10. The average CH3CCH abundance is about 7 x 10^-9. It shows a shallow, positive correlation with the temperature, whereas SiO shows the opposite tendency. Conclusions. We suggest that the high CH3CCH abundance and its possible increase when the clouds get warmer is related to the intensified desorption of the chemical precursors of the molecule from grain surfaces. In contrast, the observed tendency of SiO does not support the idea that the evaporation of Si-containing species from the grain mantles would be important, and it contradicts with the models where neutral reactions with activation barriers dominate the SiO production. A possible explanation for the decrease is that warmer cores represent more evolved stages of core evolution with fewer high-velocity shocks and thus less efficient SiO replenishment.
