description: Superconducting topological metals (SCTMs) have recently emerged as a promising platform of topological superconductivity (TSC) and Majorana zero modes(MZMs) for quantum computation. Despite their importance in both fundamental research and applications, SCTMs are very rare in nature. In addition, some superconductors with topological electronic structures have been reported recently, but a feasible program to determine their TSC properties is still lacking. Here, we propose a new strategy to design SCTMs by intercalating the superconducting units into the topological insulators. A program that characterizes the superconducting BdG Chern number of 2D BdG Hamiltonian from ab initio calculations is also developed. Following this strategy, PdBi$_2$Te$_5$ and PdBi$_2$Te$_4$ are found to be experimentally synthesizable and ideal SCTMs. Chiral TSC could be realized in such SCTMs by incorporating topological surface states with Zeeman effect, which can be realized by an external magnetic field or in proximity to ferromagnetic (FM) insulator. Our strategy provides a new method for identifying the SCTMs and TSC candidates, and the program makes it possible to design and modulate the TSC candidates from ab initio calculations.
Self-ratcheting Stokes drops driven by oblique vibrations

description: We develop and analyze a minimal hydrodynamic model in the overdamped limit to understand why a drop climbs a smooth homogeneous incline that is harmonically vibrated at an angle different from the substrate normal [Brunet, Eggers and Deegan, Phys. Rev. Lett. 99, 144501 (2007)]. We find that the vibration component orthogonal to the substrate induces a nonlinear (anharmonic) response in the drop shape. This results in an asymmetric response of the drop to the parallel vibration and, in consequence, in the observed net motion. Beside establishing the basic mechanism, we identify scaling laws valid in a broad frequency range and a flow reversal at high frequencies.

description: Optical fiber tapers are used to collect photoluminescence emission at ~1.5 um from photonic crystal cavities fabricated in erbium doped silicon nitride on silicon. Photoluminescence collection via fiber taper is enhanced 2.5 times relative to free space, with a total taper collection efficiency of 53%. By varying the fiber taper offset from the cavity, a broad tuning range of coupling strength is obtained. This material system combined with fiber taper collection is promising for building on-chip optical amplifiers.

description: Integrated sensing and communication (ISAC) has the advantages of efficient spectrum utilization and low hardware cost. It is promising to be implemented in the fifth-generation-advanced (5G-A) and sixth-generation (6G) mobile communication systems, having the potential to be applied in intelligent applications requiring both communication and high-accurate sensing capabilities. As the fundamental technology of ISAC, ISAC signal directly impacts the performance of sensing and communication. This article systematically reviews the literature on ISAC signals from the perspective of mobile communication systems, including ISAC signal design, ISAC signal processing algorithms and ISAC signal optimization. We first review the ISAC signal design based on 5G, 5G-A and 6G mobile communication systems. Then, radar signal processing methods are reviewed for ISAC signals, mainly including the channel information matrix method, spectrum lines estimator method and super resolution method. In terms of signal optimization, we summarize peak-to-average power ratio (PAPR) optimization, interference management, and adaptive signal optimization for ISAC signals. This article may provide the guidelines for the research of ISAC signals in 5G-A and 6G mobile communication systems.

description: The energy structure of an anisotropically interacting Kitaev model on a honeycomb lattice under triaxial strain is investigated. A numerical calculation shows that quantized states appear in the low-energy region, even when the anisotropy of the interaction is rather strong. Their energies are proportional to the square root of the quantum number and the quantized state at zero energy appears only on one sublattice. These findings indicate the emergence of the strain-induced Landau levels of Majorana fermions, which is also confirmed by an analytical calculation. These Landau levels are stable, when the direction of triaxial strain is slightly changed from the bond direction.

description: We study convergent (terminating and confluent) presentations of n-categories. Using the notion of polygraph (or computad), we introduce the homotopical property of finite derivation type for n-categories, generalizing the one introduced by Squier for word rewriting systems. We characterize this property by using the notion of critical branching. In particular, we define sufficient conditions for an n-category to have finite derivation type. Through examples, we present several techniques based on derivations of 2-categories to study convergent presentations by 3-polygraphs.

Optical-pumping enantio-conversion of chiral mixtures in presence of tunneling between chiral states

description: Enantio-conversion of chiral mixtures, converting the mixtures composed of left- and right-handed chiral molecules into the homochiral ensembles, has become an important research topic in chemical and biological fields. In previous studies on enantio-conversion, the tunneling interaction between the left- and right-handed chiral states was often neglected. However, for certain chiral molecules, this tunneling interaction is significant and cannot be ignored. Here we propose a scheme for enantio-conversion of chiral mixtures through optical pumping based on a four-level model of chiral molecules, comprising two chiral ground states and two achiral excited states, with a tunneling interaction between the chiral states. Under one-photon large detuning and two-photon resonance conditions, one of the achiral excited states is eliminated adiabatically. By well designing the detuning and coupling strengths of the electromagnetic fields, the tunneling interaction between two chiral states and the interaction between one of the chiral states and the remaining achiral excited state can be eliminated. Consequently, one chiral state remains unchanged, while the other can be excited to an achiral excited state, establishing chiral-state-selective excitations. By numerically calculating the populations of two chiral ground states and the enantiomeric excess, we observe that high-efficiency enantio-conversion is achieved under the combined effects of system dissipation and chiral-state-selective excitations.

After introducing a Lifshitz scalar for a general background, we analyze the cosmology of the model in Lorentzian and Euclidean signature. Vacuum solutions are found and it is argued the existence of non-singular bouncing profiles. We find a general qualitative agreement with both the picture of Causal Dynamical Triangulations and Quantum Einstein Gravity. However, inflation driven by a Lifshitz scalar field on a classical background might not produce a scale-invariant spectrum when the principle of detailed balance is assumed.

Venous physiology of aldosterone and bradykinin in health and chronic heart failure
Creators: name: Gunaruwan, Thevarathanthirige Punsiri Prasad
Publisher: name: University Of Tasmania
Year: 2023

description: In this thesis I examined vascular physiology, with an emphasis on venous physiology, of two important neuro-hormones, aldosterone and bradykinin, in health and in chronic heart failure. Capacitance venous tone governs the volume of blood in the peripheral vs. central circulation and thus indirectly influences cardiac output. Mechanisms that control venous tone in health and in heart failure are poorly understood. Chapter 1 discusses the importance of venous physiology in governing cardiac output in health and heart failure. The significance of pressure volume relationships, rather than pressure flow relationships in capacitance veins is explained. The physiological measures and the terms used to describing changes in parameters are defined. Chapter 2 is a literature review of pharmacology and physiology of aldosterone and bradykinin, with an emphasis on vascular physiology in health and in chronic heart failure. Chapter 3 describes in detail our methods of assessing both resistance and capacitance vascular functions. It examines changes to vasculature with a semi-supine posture, relationship between arterial flow and venous capacitance, and compares two established techniques in assessing capacitance veins. Chapter 4, 5 and 6 examines in detail the effects of aldosterone and bradykinin on human forearm vasculature, and differences in vascular responses between states of health and heart failure are discussed. The important new findings of this thesis are: 1. In physiological concentrations, aldosterone does not acutely alter vascular physiology in health. 2. In contrast, in treated heart failure aldosterone decreases blood flow in resistance vessels but not in capacitance vessels 3. Bradylcinin modulates venous capacitance in health via its Type 2 receptor. However, bradykinin does not contribute to basal vascular tone in health 4. In angiotensin-converting-enzyme-inhibitor-treated heart failure, bradykinin contributes to basal venous tone. In contrast, bradykinin does not contribute to venous tone in heart failure treated with angiotensin II receptor antagonists. 5. In mild to moderate heart failure bradykinin effects are mediated via the Type 2 Bradykinin receptor. 6. A paradoxical enhanced venodilatation was discovered in heart failure patients on both aspirin and angiotensin converting enzyme inhibitors, in comparison to those only on the latter.

A Direct Measurement of the IGM Opacity to HI Ionizing Photons

description: We present a new method to directly measure the opacity from HI Lyman limit (LL) absorption k_LL along quasar sightlines by the intergalactic medium (IGM). The approach analyzes the average (``stacked'') spectrum of an ensemble of quasars at a common redshift to infer the mean free path (MFP) to ionizing radiation. We apply this technique to 1800 quasars at z=3.50-4.34 drawn from the Sloan Digital Sky Survey (SDSS), giving the most precise measurements on k_LL at any redshift. From z=3.6 to 4.3, the opacity increases steadily as expected and is well parameterized by MFP = (48.4 +/- 2.1) - (38.0 +/- 5.3)*(z-3.6) h^-1 Mpc (proper distance). The relatively high MFP values indicate that the incidence of systems which dominate k_LL evolves less strongly at z>3 than that of the Lya forest. We infer a mean free path three times higher than some previous estimates, a result which has important implications for the photo-ionization rate derived from the emissivity of star forming galaxies and quasars. Finally, our analysis reveals a previously unreported, systematic bias in the SDSS quasar sample related to the survey's color targeting criteria. This bias potentially affects all z~3 IGM studies using the SDSS database.

description: The Koopman framework is a popular approach to transform a finite dimensional nonlinear system into an infinite dimensional, but linear model through a lifting process, using so-called observable functions. While there is an extensive theory on infinite dimensional representations in the operator sense, there are few constructive results on how to select the observables to realize them. When it comes to the possibility of finite Koopman representations, which are highly important form a practical point of view, there is no constructive theory. Hence, in practice, often a data-based method and ad-hoc choice of the observable functions is used. When truncating to a finite number of basis, there is also no clear indication of the introduced approximation error. In this paper, we propose a systematic method to compute the finite dimensional Koopman embedding of a specific class of polynomial nonlinear systems in continuous-time such that, the embedding, without approximation, can fully represent the dynamics of the nonlinear system.

Publisher: name: University Of Tasmania

description: A quantitative analysis of sister chromatid exchanges and labelling patterns in H 3 thymidine labelled second division (post isotope incorporation) chromosomes of Vicia faba has demonstrated that: (1) The frequency of sister chromatid exchanges per chromosome is proportional to chromosome length. (2) The time of availability of colchicine may have a slight effect on the prospects of sister chromatid exchange events. However, overall, colchicine has no significant effect on the frequency of sister chromatid exchanges; on the incidence of isolabelling or on the type of iso-labelling (3) The distribution of sister chromatid exchanges per chromosome follows a Poissonian form. The prospects of sister chromatid exchange events at either the first or second interphases are equal and independent. (4) The ratio of single to twin sister chromatid exchange is consistent with the expectation that; sister chromatid exchanges occur independently of the tritium dose, and that chromosomal sub-units rejoin non-randomly, i.e. they exhibit polarity and are dissimilar in an analagous manner to the DNA double helix. (5) A high frequency of chromosomes show isolabelling, the probability of which increases with chromosome length and/or exchange frequency. (6) Twin and single isolabelling segments have been noted, however the ratios obtained do not fit those for sister chromatid exchanges and the origin of isolabelling remains unexplained. Mitotic cycle determinations using the labelled mitosis wave method and the double labelling method have been carried out for Vicia faba and Spironema fragrans root tips. The variability of such methods has been commented on.

description: Aromatic B-series were introduced as an extension of standard Butcher-series for the study of volume-preserving integrators. It was proven with their help that the only volume-preserving B-series method is the exact flow of the differential equation. The question was raised whether there exists a volume-preserving integrator that can be expanded as an aromatic B-series. In this work, we introduce a new algebraic tool, called the aromatic bicomplex, similar to the variational bicomplex in variational calculus. We prove the exactness of this bicomplex and use it to describe explicitly the key object in the study of volume-preserving integrators: the aromatic forms of vanishing divergence. The analysis provides us with a handful of new tools to study aromatic B-series, gives insights on the process of integration by parts of trees, and allows to describe explicitly the aromatic B-series of a volume-preserving integrator. In particular, we conclude that an aromatic Runge-Kutta method cannot preserve volume.

description: Automation in the life science research laboratory is a paradigm that has gained increasing relevance in recent years. Current robotic solutions often have a limited scope, which reduces their acceptance and prevents the realization of complex workflows. The transport and manipulation of laboratory supplies with a robot is a particular case where this limitation manifests. In this paper, we deduce a taxonomy of biolaboratory liquid containers that clarifies the need for a flexible grasping solution. Using the taxonomy as a guideline, we design fingers for a parallel robotic gripper which are developed with a monolithic dual-extrusion 3D print that integrates rigid and soft materials to optimize gripping properties. We design fine-tuned fingertips that provide stable grasps of the containers in question. A simple actuation system and a low weight are maintained by adopting a passive compliant mechanism. The ability to resist chemicals and high temperatures and the integration with a tool exchange system render the fingers usable for daily laboratory use and complex workflows. We present the task suitability of the fingers in experiments that show the wide range of vessels that can be handled as well as their tolerance against displacements and their grasp stability.

description: In this paper, based on a weighted projection of the user-object bipartite network, we study the effects of user tastes on the mass-diffusion-based personalized recommendation algorithm, where a user's tastes or interests are defined by the average degree of the objects he has collected. We argue that the initial recommendation power located on the objects should be determined by both of their degree and the users' tastes. By introducing a tunable parameter, the user taste effects on the configuration of initial recommendation power distribution are investigated. The numerical results indicate that the presented algorithm could improve the accuracy, measured by the average ranking score, more importantly, we find that when the data is sparse, the algorithm should give more recommendation power to the objects whose degrees are close to the users' tastes, while when the data becomes dense, it should assign more power on the objects whose degrees are significantly different from user's tastes.

Vibration analysis by holographic interferometry

Publisher: name: University of British Columbia
Year: 2011

description: Holographic interferometry offers tremendous potential in the analysis of small amplitude vibrations of three dimensional objects. Due to stability requirements and the necessity of a coherent light source, the analysis is still limited to the laboratory. In this experiment the various holography systems for vibration analysis developed to date were investigated. Secondly, a real time holographic interferometry technique was developed for quantitatively mapping the complete dynamic field of a surface, where the amplitudes of vibration are on the order of the wavelength of light used. This technique offers the following features: (a) The phase of the object can be determined. (b) The exact resonant frequency can be pinpointed by observing the phase change of the vibrating object (c) Entire displacement fields can be determined, even though the maximum amplitudes of vibrations are on the order of only a few microinches. (d) Under continuous illumination the mode shape of the object can be readily observed.

Model independence implies more free parameters than assumed in previous studies. Using data from atomic clocks based on $^{87}$Sr, $^{171}$Yb$^+$ and $^{133}$Cs, we set bounds on parameters controlling the variation of the fine-structure constant, $α$, and the electron-to-proton mass ratio, $μ$. We consider variations on timescales ranging from a minute to almost a day. In addition, we use our results to derive some of the tightest limits to date on the parameter space of models of ultralight dark matter and axion-like particles.

description: High-cadence, multiwavelength optical observations of a solar active region (NOAA 10969), obtained with the Swedish Solar Telescope, are presented. Difference imaging of white light continuum data reveals a white light brightening, 2 min in duration, linked to a co-temporal and co-spatial C2.0 flare event. The flare kernel observed in the white light images has a diameter of 300 km, thus rendering it below the resolution limit of most space-based telescopes. Continuum emission is present only during the impulsive stage of the flare, with the effects of chromospheric emission subsequently delayed by approximately 2 min. The localized flare emission peaks at 300% above the quiescent flux. This large, yet tightly confined, increase in emission is only resolvable due to the high spatial resolution of the Swedish Solar Telescope. An investigation of the line-of-sight magnetic field derived from simultaneous MDI data shows that the continuum brightening is located very close to a magnetic polarity inversion line. Additionally, an H-alpha flare ribbon is directed along a region of rapid magnetic energy change, with the footpoints of the ribbon remaining co-spatial with the observed white light brightening throughout the duration of the flare. The observed flare parameters are compared with current observations and theoretical models for M- and X-class events and we determine the observed white-light emission is caused by radiative back warming. We suggest that the creation of white-light emission is a common feature of all solar flares.

description: Using wide-field $BVR_cI$ imaging for a sample of 16 intermediate redshift ($0.17 < z < 0.55$) galaxy clusters from the Canadian Network for Observational Cosmology (CNOC1) Survey, we investigate the dependence of cluster galaxy populations and their evolution on environment. Galaxy photometric redshifts are estimated using an empirical photometric redshift technique and galaxy groups are identified using a modified friends-of-friends algorithm in photometric redshift space.We utilize the red galaxy fraction (\fred) to infer the evolutionary status of galaxies in clusters, using both individual galaxies and galaxies in groups. We apply the local galaxy density, \sig5, derived using the fifth nearest-neighbor distance, as a measure of local environment, and the cluster-centric radius, \rCL, as a proxy for global cluster environment. Our cluster sample exhibits a Butcher-Oemler effect in both luminosity-selected and stellar-mass-selected samples. We find that \fred depends strongly on \sig5 and \rCL, and the Butcher-Oemler effect is observed in all \sig5 and \rCL bins. However, when the cluster galaxies are separated into \rCL bins, or into group and non-group subsamples, the dependence on local galaxy density becomes much weaker. This suggests that the properties of the dark matter halo in which the galaxy resides have a dominant effect on its galaxy population and evolutionary history. We find that our data are consistent with the scenario that cluster galaxies situated in successively richer groups (i.e., more massive dark matter halos) reach a high \fred value at earlier redshifts. Associated with this, we observe a clear signature of `pre-processing', in which ...

description: The efficacy of Electroencephalogram (EEG) classifiers can be augmented by increasing the quantity of available data. In the case of geometric deep learning classifiers, the input consists of spatial covariance matrices derived from EEGs. In order to synthesize these spatial covariance matrices and facilitate future improvements of geometric deep learning classifiers, we propose a generative modeling technique based on state-of-the-art score-based models. The quality of generated samples is evaluated through visual and quantitative assessments using a left/right-hand-movement motor imagery dataset. The exceptional pixel-level resolution of these generative samples highlights the formidable capacity of score-based generative modeling. Additionally, the center (Frechet mean) of the generated samples aligns with neurophysiological evidence that event-related desynchronization and synchronization occur on electrodes C3 and C4 within the Mu and Beta frequency bands during motor imagery processing. The quantitative evaluation revealed that 84.3% of the generated samples could be accurately predicted by a pre-trained classifier and an improvement of up to 8.7% in the average accuracy over ten runs for a specific test subject in a holdout experiment.

description: We investigate the performance of the variational quantum eigensolver (VQE) for the optimal flight gate assignment problem. This problem is a combinatorial optimization problem that aims at finding an optimal assignment of flights to the gates of an airport, in order to minimize the passenger travel time. To study the problem, we adopt a qubit-efficient binary encoding with a cyclic mapping, which is suitable for a digital quantum computer. Using this encoding in conjunction with the Conditional Value at Risk (CVaR) as an aggregation function, we systematically explore the performance of the approach by classically simulating the CVaR-VQE. Our results indicate that the method allows for finding a good solution with high probability, and the method significantly outperforms the naive VQE approach. We examine the role of entanglement for the performance, and find that ansätze with entangling gates allow for better results than pure product states. Studying the problem for various sizes, our numerical data show that the scaling of the number of cost function calls for obtaining a good solution is not exponential for the regimes we investigate in this work.
Some aspects in the surface chemistry of metals

description: This thesis has been divided into the following sections:- Section I : The Dehydration of Ferrous Oxalate Dihydrate. Section III Kinetics of the oxidation of Nickel Powders. Section III : Surface Area Measurements of Nickel Powders. Section IV : Heat of adsorption Measurements. Seetion I is isolated and bears little relation to the work reported in the other sections. It is, however, part of a larger programme of work on the chemistry of metal oxalates undertaken in the Department or Chemistry, Unversity of Tasmania. Sections II and III are related in that the work described in Section III followed are a direct consequence the results of Section II. The work described in both these sections was commenced under the direct supervision of Dr. J.A. Allen, formerly Senior Lecturer in Physical Chemistry, University of Tasmania. The choice of a volumetric method and the use of nickel powders in Section II was made because or the following: (a) A high vacuum apparatus had been constructed for previous work and could be used without serious modification as a volumetric apparatus. (b) Previous work in the Chemistry Department, University of Tasmania had suggested that nickel powders produced by the thermal decomposition of nickel oxalate would be suitable material for oxidation studies. Section IV has been subdivided into Parts I and II. Part I describes attempts to design and construct a calorimeter suitable for the measurement of heats of adsorption Of gases on finely divided powders. Part II is concerned with actual measurements of heats of adsorption of several gases on nickel oxide. The work described in this section was undertaken without direct supervision and all glass construction work, described in this section, has been done by the author.

description: The small cross section of Raman scattering poses a great challenge for its direct study at the single-molecule level. By exploiting the high Franck-Condon factor of a common-mode resonance, choosing a large vibrational frequency difference in electronic ground and excited states and operation at T < 2K, we succeed at driving a coherent stimulated Raman transition in individual molecules. We observe and model a spectral splitting that serves as a characteristic signature of the phenomenon at hand. Our study sets the ground for exploiting the intrinsic optomechanical degrees of freedom of molecules for applications in solid-state quantum optics and information processing.

description: Wie können Jugendliche lernen, mit zunehmender religiöser Vielfalt umzugehen?
Was kann Schule, was können LehrerInnen vermitteln, damit sich junge Menschen
in dieser Pluralität orientieren und zurechtfinden können und so auch in
ihrer Lebenswelt bestehen? Nach einem Blick auf die Situation Jugendlicher werden
im vorliegenden Beitrag Kriterien für eine kritische Reflexion nach „innen“
und „außen“ erörtert. Letztlich werden für personales und soziales Lernen „Positionalität“
ebenso eingefordert wie eine „weltoffene Perspektive“. Erfahrungen
von Studierenden der Kirchlichen Pädagogischen Hochschule (KPH) Edith Stein
in Zusammenhang mit der LV „Pluralität religiöser Phänomene“ fließen in den
Beitrag ein.
description: How can teenagers learn to handle ever increasing religious diversity? What can
school or teachers provide in order for young people to be able to orientate
themselves in this plurality and persist in their own environment. After looking
at the situation of teenagers, this entry analyses criteria for a critical reflection
on the inside and the outside. Ultimately “personality” and a “cosmopolitan perspective”
are required for personal and social learning. The experience of students
of the KPH Edith Stein in connection with the course “Plurality of religious
phenomenon” is incorporated in this paper.

description: Transiting planet discoveries have yielded a plethora of information regarding the internal structure and atmospheres of extra-solar planets. These discoveries have been restricted to the low-periastron distance regime due to the bias inherent in the geometric transit probability. Monitoring known radial velocity planets at predicted transit times is a proven method of detecting transits, and presents an avenue through which to explore the mass-radius relationship of exoplanets in new regions of period/periastron space. Here we describe transit window calculations for known radial velocity planets, techniques for refining their transit ephemerides, target selection criteria, and observational methods for obtaining maximum coverage of transit windows. These methods are currently being implemented by the Transit Ephemeris Refinement and Monitoring Survey (TERMS).

Abstract
Foslevodopa/foscarbidopa [PRODUODOPA® (EU); VYALEV™ (USA, Canada, Japan)] is a soluble formulation of levodopa and carbidopa prodrugs for 24-h continuous subcutaneous (SC) infusion. It is approved for the treatment of motor fluctuations in patients with advanced Parkinson’s disease (PD). Administered via an ambulatory infusion pump, it allows for personalized dosing based on individual needs. In a randomized, double-blind, double-dummy trial, continuous SC infusion of foslevodopa/foscarbidopa provided a significant and clinically meaningful increase in hours of ‘on’ time without troublesome dyskinesia and a reduction in hours of ‘off’ time compared with oral immediate-release levodopa/carbidopa. The benefits of foslevodopa/foscarbidopa were maintained over the longer term (up to 124 weeks). Continuous SC infusion of foslevodopa/foscarbidopa was generally well tolerated, including over the longer term. However, infusion site events were common, necessitating regular monitoring, cannula replacement, infusion site rotation and aseptic techniques. Although further long-term data are required, foslevodopa/foscarbidopa represents a promising non-surgical alternative to the available device-aided therapies for patients with advanced PD whose motor fluctuations are inadequately controlled by other oral PD medications.
