description: Ventricular fibrillation (VF) is a lifethreatening electromechanical dysfunction of the heart associated with complex spatiotemporal dynamics of electrical excitation and mechanical contraction of the heart muscle. It has been hypothesized that VF is driven by three-dimensional (3D) rotating electrical scroll waves, which can be characterized by filament-like electrical phase singularities (EPS). Recently, it was shown that rotating excitation waves during VF are associated with rotating waves of mechanical deformation. 3D mechanical scroll waves and mechanical filaments describing their rotational core were observed in the ventricles by using high-resolution ultrasound. The findings suggest that the spatiotemporal organization of cardiac fibrillation may be assessed from waves of mechanical deformation. However, the complex relationship between excitation and mechanical waves during VF is currently not understood. Here, we study the fundamental nature of mechanical phase singularities (MPS), their spatiotemporal organization and relation with EPS. We demonstrate the existence of two fundamental types of MPS: "paired singularities", which are co-localized with EPS, and "unpaired singularities", which can form independently. We show that the unpaired singularities emerge due to the anisotropy of the active force field, generated by fiber anisotropy in cardiac tissue, and the non-locality of elastic interactions, which jointly induce strong spatiotemporal inhomogeneities in the strain fields. The inhomogeneities lead to the breakup of deformation waves and create MPS, even in the absence of EPS, which are typically associated with excitation wave break. We exploit these insights to develop an approach to discriminate paired and unpaired MPS. Our findings provide a fundamental understanding of the complex spatiotemporal organization of electromechanical waves in the heart.

description: The coupling between the spin and momentum degrees of freedom due to spin-orbit interactions (SOI) suggests that the strength of the latter can be modified by controlling the motion of the charge carriers. In this paper, we investigate how the effective SOI can be modulated by constraining the motion of charge carriers to curved waveguides thereby introducing real-space geometric curvature in their motion. The change in the SOI can in turn induce topological phase transitions in the system. Specifically, we study how the introduction of periodic sinusoidal curvature in nanowires with intrinsic SOC can induce the onset of mid-gap topologically protected edge states, which can be characterized by a topological invariant or Chern number. The Chern number corresponds to the number of discrete charges that would be pumped across the length of the nanowire when the phase of a sliding gate potential relative to that of the sinusoidal curvature is varied adiabatically over a complete period. In addition, coupling to an external magnetization can be utilized as an experimental knob to modify the Chern number by changing the ordering of the nanowire energy bands. The magnetization can be tuned to achieve large discrete jumps in the number of pump charges per phase period.

description: Die Versuche wurden an isolierten Organen des Meerschweichens mit der Substanz JB23 (N-(3,5-Dimethoxypenyl)-4'-trifluormethoxybenzamid), die von Herrn Prof. Erker zur Verfügung gestellt und am Insitut für Organische Chemie an der Universität Wien synthetisiert wurde, durchgeführt. Alle Versuchstiere stammten aus einer Versuchstierzucht in Himberg (Niederösterreich). Verwendet wurden weibliche und männliche Tiere vom durchschnittlichen Körpergewicht von 300-800g. Zur Präparation wurden folgende Organe entnommen: Arteria pulmonalis, rechter Vorhof, Papillarmuskel, Aorta, terminales Ileum und Uterus. Die Organpräparate wurden in mit Oxymix durchperlten Nährlösungen (Tyroden) aufbewahrt. Stammlösungen der Testsubstanz wurden täglich frisch zubereitet und die Badkonzentrationen wurden berehnet für 0,1µmol/l, 0,3µmol/l, 1µmol/l, 3µmol/, 10µmol/l, 30µmol/l, 100µmol/l und 300µml/l. Zusätzlich zu den Versuchen mit der Testsubstnz, um deren Einfluss auf die glatte Muskulatur und mögliche chronotrope bzw. inotrope Wirkung zur erforschen, wurden auch zur Aufkärung möglichen Wirkungsmechanismus Kombinationsversuche der Testsubstanz mit unterschiedlichen Agonisten (Histamindihydrochlorid, Acetylcholinhydrochlorid und Phenylephrinhydrochlorid) durchgeführt. Diese Kombinationsversuche wurden am terminalen Ileum und am Uterus durchgeführt. Bei den Versuchen: -am rechten Vorhof wurde eine negativ chronotrope Wirkung festgestellt (Verminderung der Schlafrequenz ab der ersten Kozentrationsstufe er Testsubstanz); -am Papillarmuskel leichte Zunahme der Kontraktionskraft, erst ab Konzentrationsstufe 100µmol/l Abnahme, -an der Aorta Abnahme der Kontraktionskraft -auf der Arteria pulmonalis keine signifikante Abnahme der Kontraktionskraft; -am terminalen Ileum eine stark relaxierende Wirkung. Bei den Kombinationsversuchen am terminalen Ileum -mit Histamin-Zunahme, -mit Acetylcholin-Abnahme, -mit Phenylephrin-Abnahme der Kontraktionskraft, bei Kombinationsversuchen mit Histamin am Uterus-Abnahme der Kontraktionskraft festgestellt. Vergleich mit Resveratrol: sehr starke chronotrope Wirkung der Testsubstanz (ausgeprägter als bei Resveratrol), stärker relaxierender Effekt als bei Resveratrol, eventuelle histaminerge und anticholinerge Wirkung.

description: The treatment of electronic correlations in open-shell systems is among the most challenging problems of condensed matter theory. Current approximations are only partly successful. Ligand field multiplet theory (LFMT) has been widely successful in describing intra-atomic correlation effects in x-ray spectra, but typically ignores itinerant states. The cumulant expansion for the one electron Greens function has been successful in describing shake-up effects but ignores atomic multiplets. More complete methods, such as dynamic mean-field theory can be computationally problematic. Here we show that separating the dynamic Coulomb interactions into local and longer-range parts with ab initio parameters yields a combined multiplet plus cumulant approach that accounts for both local atomic multiplets and satellite excitations. The approach is illustrated in transition metal oxides and explains the multiplet peaks, charge-transfer satellites and distributed background features observed in XPS experiment.

description: In the study of quantum vacuum energy and the Casimir effect, it is desirable to model the conductor by a potential of the form $V(z)=z^α$. This "soft wall" model was proposed so as to avoid the violation of the principle of virtual work under ultraviolet regularization that occurs for the standard Dirichlet wall. The model was formalized for a massless scalar field, and the expectation value of the stress tensor has been expressed in terms of the reduced Green function of the equation of motion. In the limit of interest, $α\gg 1$, which approximates a Dirichlet wall, a closed-form expression for the reduced Green function cannot be found, so piecewise approximations incorporating the perturbative and WKB expansions of the Green function, along with interpolating splines in the region where neither expansion is valid, have been developed. After reviewing this program, in this article we apply the scheme to the wall with $α=6$ and use it to compute the renormalized energy density and pressure inside the cavity for various values of the conformal parameter. The consistency of the results is verified by comparison to their numerical counterparts and verification of the trace anomaly and the conservation law. Finally, we use the approximation scheme to reproduce the energy density inside the quadratic wall, which was previously calculated exactly but with some uncertainty.

Energy scales and black hole pseudospectra: the structural role of the scalar product
Creators: name: Gasperin, Edgar

Publisher: name: arXiv
Year: 2021
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: A pseudospectrum analysis has recently provided evidence of a potential generic instability of black hole (BH) quasinormal mode (QNM) overtones under high-frequency perturbations. Such instability analysis depends on the assessment of the size of perturbations. This is encoded in the scalar product and its choice is not unique. We address the impact of the scalar product choice, founding it on the physical energy scales of the problem. The article is organized in three parts: basics, applications and heuristic proposals. In the first part, we revisit the energy scalar product used in the hyperboloidal approach to QNMs, extending previous effective analyses and placing them on solid spacetime basis. The second part focuses on applications of the scalar product in the QNM problem: i) we demonstrate that the QNM instability is not an artifact of previous spectral numerical schemes, by implementing a finite elements calculation from a weak formulation; ii) using Keldysh's theorem, we provide QNM resonant expansions for the gravitational waveform, with explicit expressions of the expansion coefficients; iii) we propose the notion of "epsilon-dual QNM expansions" to exploit BH QNM instability in BH spectroscopy, exploiting both non-perturbed and perturbed QNMs, the former informing on large scales and the latter probing small scales. The third part enlarges the conceptual scope of BH QNM instability proposing: a) spiked perturbations are more efficient in triggering BH QNM instabilities than smooth ones, b) a general picture of the BH QNM instability problem is given, supporting the conjecture (built on Burnett's conjecture) that Nollert-Price branches converge universally to logarithmic Regge branches in the high-frequency limit and c) aiming at a fully geometric description of QNMs, BMS states are hinted as possible asymptotic/boundary degrees of freedom for an inverse scattering problem.

description: These days, there is an emerging pattern in both large corporations and smaller businesses ofemployees conducting business from their homes. The majority of workers are now completingtheir duties at home. Under this operational model, there has been an increase in theproductivity of workers, but there has also been the emergence of a new challenge forbusinesses, which is to secure the integrity of their data as well as their systems. As is wellknown, the safety of a company's technological systems and the reliability of its data are bothof the utmost importance to that company. A significant amount of capital is being invested bybusinesses in the protection of their information and computer systems. Since it is commonknowledge that many employees are now working from home in the wake of COVID, securingthe data and the system is made more difficult by the fact that employees are working awayfrom the physical locations of their employers. Therefore, it is very difficult to ensure that aworker's laptop is kept in a secure environment And even we don’t know about the activities ofemployees. Employee who currently work or have worked in the past for an organization andwho have authorized access to its networks, systems, and/or data. However, instead offulfilling their duties, these individuals use their privileged position to carry out malicious actsthat may include theft of intellectual property or information. To address this security threat,many enterprise organizations are actively seeking to develop and implement solutions todetect and prevent insider threats. Absence of monitoring or control Any cybercriminal cansteal sensitive information by hacking into the employee's laptop and gaining access to it.Even though many businesses have firewalls and numerous SIEM systems in place to protecttheir data, there are still frequent instances of security flaws occurring in these businesses. Inorder to solve this issue, we make use of the User and Entity Behavior Analysis (UEBA)method and put into action some clever solutions by combining big data tools, machinelearning, and deep learning models.

description: We present the solution of the weak noise theory (WNT) for the Kardar-Parisi-Zhang equation in one dimension at short time for flat initial condition (IC). The non-linear hydrodynamic equations of the WNT are solved analytically through a connexion to the Zakharov-Shabat (ZS) system using its classical integrability. This approach is based on a recently developed Fredholm determinant framework previously applied to the droplet IC. The flat IC provides the case for a non-vanishing boundary condition of the ZS system and yields a richer solitonic structure comprising the appearance of multiple branches of the Lambert function. As a byproduct, we obtain the explicit solution of the WNT for the Brownian IC, which undergoes a dynamical phase transition. We elucidate its mechanism by showing that the related spontaneous breaking of the spatial symmetry arises from the interplay between two solitons with different rapidities.

description: We develop a physics-informed machine learning approach for large-scale data assimilation and parameter estimation and apply it for estimating transmissivity and hydraulic head in the two-dimensional steady-state subsurface flow model of the Hanford Site given synthetic measurements of said variables. In our approach, we extend the physics-informed conditional Karhunen-Loéve expansion (PICKLE) method for modeling subsurface flow with unknown flux (Neumann) and varying head (Dirichlet) boundary conditions. We demonstrate that the PICKLE method is comparable in accuracy with the standard maximum a posteriori (MAP) method, but is significantly faster than MAP for large-scale problems. Both methods use a mesh to discretize the computational domain. In MAP, the parameters and states are discretized on the mesh; therefore, the size of the MAP parameter estimation problem directly depends on the mesh size. In PICKLE, the mesh is used to evaluate the residuals of the governing equation, while the parameters and states are approximated by the truncated conditional Karhunen-Loéve expansions with the number of parameters controlled by the smoothness of the parameter and state fields, and not by the mesh size. For a considered example, we demonstrate that the computational cost of PICKLE increases near linearly (as $N_{FV}^{1.15}$) with the number of grid points $N_{FV}$, while that of MAP increases much faster as $N_{FV}^{3.28}$. We demonstrated that once trained for one set of Dirichlet boundary conditions (i.e., one river stage), the PICKLE method provides accurate estimates of the hydraulic head for any value of the Dirichlet boundary conditions (i.e., for any river stage).

Tribe: Thlaspideae DC.
Notes. – A genus of three Eurasian species, and the generic type, Thlaspi arvense L., is a cosmopolitan weed and cultivated plant.
As recognized by CANDOLLE (1821 a, 1821b), BOISSIER (1867a), and subsequent authors prior to 1973, Thlaspi was so broadly delimited to include over 100 species. MEYER (1973, 1979) retained only six species in the genus and transferred the remaining taxa into a dozen segregates based primarily on seed-coat anatomy.
However, subsequent authors (e.g., GREUTER et al., 1986; APPEL & AL-SHEHBAZ, 2003) retained the genus in the broad sense, whereas others (e.g., AL-SHEHBAZ, 2012, 2014) relied on the available molecular data and placed all except six species in Noccaea of the tribe Coluteocarpeae. The latter genus also currently encompasses almost all taxa described in Iberidella by BOISSIER (1841b).
As recently delimited, ESMAILBEGI et al. (2018) recognized only four species in Thlaspi, of which T. kochianum F.K. Mey. was subsequently reduced by GERMAN (2018) to the following species.

description: The study of the generation of metric perturbation in the laboratory presents an opportunity to observe and understand more easily the mechanisms at work in gravitation. The present study will focus on the metric perturbation generated by a light pulse, as it could be generated by a current ultra-high power laser. Although of very small magnitude, the potential thus generated has advantages over that generated by mass acceleration, such as the absence of noise due to non uniform acceleration or the ability to scale up the experiment. It is indeed easier to scale up an electromagnetic oscillation compared to a mechanical oscillator, which must either be made with a large accelerated mass or a lot of small masses, all in sync, which acceleration must furthermore be quadripolar. Generation of metric deformation by laser could therefore prove useful in the long-term establishment of a laboratory experiment for the generation and detection of gravitational waves.

description: A sample of 14 FRBs with measured redshifts and scattering times is used to assess contributions to dispersion and scattering from the intergalactic medium (IGM), galaxy halos, and the disks of host galaxies. The IGM and galaxy halos contribute significantly to dispersion measures but evidently not to scattering, which is then dominated by host galaxies. This enables usage of scattering times for estimating DM contributions from host galaxies and also for a combined scattering-dispersion redshift estimator. Redshift estimation is calibrated using scattering of Galactic pulsars after taking into account different scattering geometries for Galactic and intergalactic lines of sight. The DM-only estimator has a bias $\sim 0.1$ and RMS error $\sim 0.15$ in the redshift estimate for an assumed ad-hoc value of 50 pc cm$^{-3}$ for the host galaxy's DM contribution. The combined redshift estimator shows less bias by a factor of four to ten and a 20 to 40% smaller RMS error. We find that values for the baryonic fraction of the ionized IGM $f_{\rm igm} \sim 0.85 \pm 0.05$ optimize redshift estimation using dispersion and scattering. Our study suggests that two of the 14 candidate galaxy associations (FRB 20190523 and FRB~20190611B) should be reconsidered.

description: High finesse optical cavities of current interferometric gravitational-wave detectors are significantly limited in sensitivity by laser quantum noise and coating thermal noise. The thermal noise is associated with internal energy dissipation in the materials that compose the test masses of the interferometer. Our understanding of how the internal friction is linked to the amorphous material structure is limited due to the complexity of the problem and the lack of studies that span over a large range of materials. We present a systematic investigation of amorphous metal oxide and Ta$_2$O$_5$-based mixed oxide coatings to evaluate their suitability for low Brownian noise experiments. It is shown that the mechanical loss of metal oxides is correlated to their amorphous morphology, with continuous random network materials such as SiO$_2$ and GeO$_2$ featuring the lowest loss angles. We evaluated different Ta$_2$O$_5$-based mixed oxide thin films and studied the influence of the dopant in the optical and elastic properties of the coating. We estimated the thermal noise associated with high-reflectance multilayer stacks that employ each of the mixed oxides as the high index material. We concluded that the current high index material of TiO$_2$-doped Ta$_2$O$_5$ is the optimal choice for reduced thermal noise among Ta$_2$O$_5$-based mixed oxide coatings with low dopant concentrations.

description: Eigenvector continuation (EC) has recently attracted a lot attention in nuclear structure and reactions as a variational resummation tool for many-body expansions. While previous applications focused on ground-state energies, excited states can be accessed on equal footing. This work is dedicated to a detailed understanding of the emergence of excited states from the eigenvector continuation approach. For numerical applications the one-dimensional quartic anharmonic oscillator is investigated, which represents a strongly non-perturbative quantum system where the use of standard perturbation techniques break down. We discuss how different choices for the construction of the EC manifold affect the quality of the EC resummation and investigate in detail the results from EC for excited states compared to results from a full diagonalization as a function of the basis-space size.

description: Peaking at 3.7 mag on 2020 July 11, YZ Ret was the second-brightest nova of the decade. The nova's moderate proximity (2.7 kpc from Gaia) provided an opportunity to explore its multi-wavelength properties in great detail. Here we report on YZ Ret as part of a long-term project to identify the physical mechanisms responsible for high-energy emission in classical novae. We use simultaneous Fermi/LAT and NuSTAR observations complemented by XMM-Newton X-ray grating spectroscopy to probe the physical parameters of the shocked ejecta and the nova-hosting white dwarf. The XMM-Newton observations revealed a super-soft X-ray emission which is dominated by emission lines of CV, CVI, NVI, NVII, and OVIII rather than a blackbody-like continuum, suggesting CO-composition of the white dwarf in a high-inclination binary system. Fermi/LAT detected YZ Ret for 15 days with the gamma-ray spectrum best described by a power law with an exponential cut-off at 1.9 +/-0.6 GeV. In stark contrast with theoretical predictions and in keeping with previous NuSTAR observations of Fermi-detected classical novae (V5855 Sgr and V906 Car), the 3.5-78 keV X-ray emission is found to be two orders of magnitude fainter than the GeV emission. The X-ray emission observed by NuSTAR is consistent with a single-temperature thermal plasma. We detect no non-thermal tail of the GeV emission expected to extend down to the NuSTAR band. NuSTAR observations continue to challenge theories of high-energy emission from shocks in novae.

description: It is known that the large-scale structure (LSS) mapped by a galaxy redshift survey is subject to distortions by galaxies' peculiar velocities. Besides the signatures generated in common N-point statistics, such as the anisotropy in the galaxy 2-point correlation function, the peculiar velocities also induce distinct features in LSS's morphological properties, which are fully described by four Minkowski functionals (MFs), i.e., the volume, surface area, integrated mean curvature and Euler characteristic (or genus). In this work, by using large suite of N-body simulations, we present and analyze these important features in the MFs of LSS on both (quasi-)linear and non-linear scales, with a focus on the latter. We also find the MFs can give competitive constraints on cosmological parameters compared to the power spectrum, probablly due to the non-linear information contained. For galaxy number density similar to the DESI BGS galaxies, the constraint on $σ_8$ from the MFs with one smoothing scale can be better by $\sim 50\%$ than from the power spectrum. These findings are important for the cosmological applications of MFs of LSS, and probablly open up a new avenue for studying the peculiar velocity field itself.

The transverse field XY model on the diamond chain

description: We consider the $s=1/2$ transverse field $XY$ model on the frustrated diamond chain, considering anisotropic exchange parameters between nearest-neighbor spins. To this end, we employ three different methodologies: mean-field approximations, and state-of-the-art exact diagonalizations (ED), and density matrix renormalization group (DMRG) simulations. Within a mean-field theory, the Hamiltonian is fermionized by introducing the Jordan-Wigner transformation, and the interacting (many-body) terms are approximated to single-particle ones by a Hartree-Fock approach. We analyze the behavior of the induced and spontaneous magnetization as functions of the external field, investigating the magnetic properties at the ground state, and at finite temperatures. Interestingly, the mean-field results are in reasonable agreement with the ED and DMRG ones, in particular for the distorted chain, or at an intermediate/large spin anisotropy parameter. As our key results, we present phase diagrams anisotropy $\times$ magnetic field at zero temperature, discussing the emergence of phases and their quantum critical points. Finally, our analysis at finite temperature provides a range of parameters in which an unusual behavior of the induced magnetization occurs -- with it increasing as a function of temperature. This work presents a \textit{global} picture of the XY model on the diamond chain, which may be useful to understand features of magnetism in more complex geometries.

description: We introduce a versatile and practical framework for applying matrix product state techniques to continuous quantum systems. We divide space into multiple segments and generate continuous basis functions for the many-body state in each segment. By combining this mapping with existing numerical Density-Matrix Renormalization Group routines, we show how one can accurately obtain the ground-state wave function, spatial correlations, and spatial entanglement entropy directly in the continuum. For a prototypical mesoscopic system of strongly-interacting bosons we demonstrate faster convergence than standard grid-based discretization. We illustrate the power of our approach by studying a superfluid-insulator transition in an external potential. We outline how one can directly apply or generalize this technique to a wide variety of experimentally relevant problems across condensed matter physics and quantum field theory.

description: Scholars have emphasized the importance of individuals’ agency in defending themselves from low quality, misleading, and false information. Research indicates that critical thinking ability, as part of individuals’ decision-making processes, should assist individuals in navigating the sea of information on the Internet. However, communication scholars haven’t agreed on a generalized instrument to measure critical thinking ability, which has blocked the greater debate on when, how, and whether critical thinking will lead to better decision making. This dissertation looks at the relationship between critical thinking ability and information systemic processing and individuals’ seeking of fitness and nutrition information on social media to update and test a new critical thinking ability scale. The new measurement is based on a previously developed scale of critical understanding of media by the European Commission for Information Society and Media Literacy Unit in 2011. After a series Exploratory Factor Analysis and Confirmatory Factor Analysis, the amended scale for critical thinking ability was formulated. The new scale addressed individuals’ skill in analyzing and comparing different information source, being aware of the common media effects, and knowing where laws and regulations of media might be applied in life. The scale consists of 12 questions, all self-reported, making it efficient and easy to be included in various cross-sectional or experimental studies. The new scale showed good internal consistency, and validity. Using the updated scale, this dissertation found direct effect of critical thinking ability on both information systematic processing and information seeking, contrary to previous assertion that information processing and seeking are largely results of information insufficiency. In the context of looking for fitness and nutrition information on social media, critical thinkers are more likely to engage in information systematic processing, but not to seek additional health information. Practical implication and future research directions were discussed.
