Field-angle-dependent low-energy excitations around a vortex in the superconducting topological insulator CuxBi2Se3

description: We study the quasiparticle excitations around a single vortex in the superconducting topological insulator Cu$_{x}$Bi$_{2}$Se$_{3}$, focusing on a superconducting state with point nodes. Inspired by the recent Knight shift measurements, we propose two ways to detect the positions of point nodes, using an explicit formula of the density of states with Kramer-Pesch approximation in the quasiclassical treatment. The zero-energy local density of states around a vortex parallel to the $c$-axis has a twofold shape and splits along the nodal direction with increasing energy; these behaviors can be detected by the scanning tunneling microscopy. An angular dependence of the density of states with a rotating magnetic field on the $a$-$b$ plane has deep minima when the magnetic field is parallel to the directions of point nodes, which can be detected by angular-resolved heat capacity and thermal conductivity measurements. All the theoretical predictions are detectable via standard experimental techniques in magnetic fields.

description: Acute presentation of upper and lower extremity motor weakness is commonly attributed to intracerebral ischemic infarct upon initial examination. For those that exhibit acute onset of bilateral weakness, it is important to expand the differential diagnosis to include spinal cord ischemic involvement. One cause of ischemic lesions is spinal dural arteriovenous (AV) fistulas which are generally found in the thoraco-lumbar region. They present with progressive paraplegia or quadriplegia due to changes in the spinal venous pressure and eventual myelopathy. We present a 60 year old gentleman with bilateral upper extremity weakness and right lower extremity weakness preceded by upper back and neck pain. Initial studies included both Magnetic resonance imagine (MRI) of the brain and also the cervical spine that demonstrated abnormal signal intensity within the anterior cervical cord from C3-C7 levels concerning for spinal cord infarct. In our case there were no flow voids to suggest dilated perimedullary vessels that usually prompt further diagnostic evaluation through a spinal angiogram. However, given the clinical suspicion, a spinal angiogram was obtained that demonstrated a cervical dural AV fistula supplied by a dural branch vessel originating from the left vertebral artery. We will highlight the importance of recognizing the clinical presentation of spinal dural AV fistulas; the usual findings on imaging, the value of considering further diagnostic tests if clinical suspicion is high, and provide an overview of the spinal dural AV treatment.

description: The paper undertakes a preliminary assessment of current developments of international law for the purpose of mapping the ground for a larger research project. The research project pursues the goal of determining whether public international law, as it has developed since the end of the Cold War, is continuing its progressive move towards a more human-rights- and multi-actor-oriented order, or whether we are seeing a renewed emphasis of more classical elements of international law. In this context the term “international rule of law” is chosen to designate the more recent and “thicker” understanding of international law. The paper discusses how it can be determined whether this form of international law continues to unfold, and whether we are witnessing challenges to this order which could give rise to more fundamental reassessments.

description: We determine the contribution of long-range pion interactions to the $X(3872)$ dynamics, assuming it is a loosely bound $D^0 \bar{D}^{*0}$ molecule. Our result is based on the distorted wave Born approximation in non-relativistic quantum mechanics. Despite their long-range nature, we find that pion interactions cannot produce a large and negative effective range. Nonetheless, they introduce imaginary parts. In particular, they contribute to the total decay width of the $X(3872)$ with a term associated with, but not precisely corresponding to, the $D^*$ width. Our approach can also be applied to the recently discovered $T_{cc}^+$ states.

description: Starless dense cores eventually collapse dynamically, which forms protostars inside them, and the physical properties of the cores determine the nature of the forming protostars. We report ALMA observations of dust continuum emission and molecular rotational lines toward MC27 or L1521F, which is considered to be very close to the first protostellar core phase. We found a few starless high-density cores, one of which has a very high density of ~10^7 cm^-3, within a region of several hundred AU around a very low-luminosity protostar detected by Spitzer. A very compact bipolar outflow with a dynamical timescale of a few hundred years was found toward the protostar. The molecular line observation shows several cores with an arc-like structure, possibly due to the dynamical gas interaction. These complex structures revealed in the present observations suggest that the initial condition of star formation is highly dynamical in nature, which is considered to be a key factor in understanding fundamental issues of star formation such as the formation of multiple stars and the origin of the initial mass function of stars.

description: In scenarios of physical interest in Loop Quantum Cosmology, with a preinflationary epoch where the kinetic energy of the inflaton dominates, the analytic study of the dynamics of the primordial fluctuations has been carried out by neglecting the inflaton potential in those stages of the evolution. In this work we develop approximations to investigate the influence of the potential as the period of kinetic dominance gives way to the inflationary regime, treating the potential as a perturbation. Specifically, we study how the potential modifies the effective mass that dictates the dynamics of the scalar perturbations in the preinflationary epochs, within the framework of the so-called hybrid prescription for Loop Quantum Cosmology. Moreover, we motivate and model a transition period that connects the kinetically dominated regime with inflation, allowing us to study the interval of times where the contribution of the potential is no longer negligible but an inflationary description is not yet valid. Finally, we include the main modifications coming from a slow-roll correction to a purely de Sitter evolution of the perturbations during inflation. We analytically solve the dynamics of the perturbations in each of these different epochs of cosmological evolution, starting from initial conditions fixed by the criterion of asymptotic Hamiltonian diagonalization. This enables us to compute and quantitatively analyze the primordial power spectrum in a specific case, using a quadratic inflaton potential.

description: Alzheimer’s disease (AD) is a progressive neurodegenerative disease characterized by the deposition of extracellular amyloid-β(Aβ) plaques that are rich in metal ions such as zinc, copper and iron. The neurotoxic role of Aβ has been well established but the mechanism of action is still poorly understood. Recent in vitro evidence suggest that Aβ can interact with metal ions such as Zn(II), Cu(II) or Fe(II/III) which promote its aggregation and/or ROS production. However, it is unclear whether this is the case in cells and whether/how extracellular Aβ can get into cells. Our recently developed molecular imaging probes for iron, copper and ROS enable us to look at this in real time in live cells at subcellular resolution. First, we tagged the Aβ covalently with a fluorescent dye which allows its interactions with cells to be monitored under a microscope. Our laser confocal imaging experiments with human neuroblastoma cells revealed that Aβ accumulated at the cell surface first and subsequently entered the cells via endocytosis pathway over a period of a few hours and finally deposited into endosomes/lysosomes in the cells. The deposition of Aβ induced a marked production of oxygen free radicals in the mitochondria of the cells, as revealed by our oxygen free radical probe and colocalization experiments. Incubation of metal ions such as copper(II) increased the production of oxygen radicals significantly while zinc(II) appears to be protective against ROS production. Our data provided compelling and direct evidence on how amyloid-β(Aβ) entering the cells and its induction of oxygen free radicals as well as the effects of metal ions on the radical production at subcellular level.

description: The COVID-19 outbreak has affected the world among all segments of the population in all possible fields of life, viz health, economic, social & educational. In India, the second wave of the pandemic brings the nightmare on repeat with a tsunami of cases. To encounter this critical situation and to safeguard the health of the students & faculty members, the education system undergoes a significant change, from conventional classroom-based learning to online interaction-based teaching-learning. This turnabout demands the availability of sufficient e-content. In this situation, OAIRs as a free-to-use platform with a voluminous amount of data, are able to help users including the institutions in coping with financial critical situations as well as enabling the learning process. This study aims to determine the current status of Indian OAIR housed in OpenDOAR by conducting a user survey to assess its importance in assisting academics and the education system during this current pandemic situation. The findings of the study reveal that DSpace (58%) is the dominant software in Indian OAIRs while English (96.43%) is the most prominent language. Additionally, the study also identifies the continual growth of Indian OAIRs with regular updation. According to the survey result, library staff and researchers are the most experienced regarding the importance and benefits of OAIRs, whereas students need to be more aware. Overall, the survey agrees with the fact that, in India, OAIRs support the significant change in the education system as well as promote web accessibility and eliminate the digital divide.

description: In recent years the use of Artificial Intelligence (AI) has become increasingly prevalent in a growing number of fields. As AI systems are being adopted in more high-stakes areas such as medicine and finance, ensuring that they are trustworthy is of increasing importance. A concern that is prominently addressed by the development and application of explainability methods, which are purported to increase trust from its users and wider society. While an increase in trust may be desirable, an analysis of literature from different research fields shows that an exclusive focus on increasing trust may not be warranted. Something which is well exemplified by the recent development in AI chatbots, which while highly coherent tend to make up facts. In this contribution, we investigate the concepts of trust, trustworthiness, and user reliance. In order to foster appropriate reliance on AI we need to prevent both disuse of these systems as well as overtrust. From our analysis of research on interpersonal trust, trust in automation, and trust in (X)AI, we identify the potential merit of the distinction between trust and distrust (in AI). We propose that alongside trust a healthy amount of distrust is of additional value for mitigating disuse and overtrust. We argue that by considering and evaluating both trust and distrust, we can ensure that users can rely appropriately on trustworthy AI, which can both be useful as well as fallible.

description: Using deep narrow-band $H_2S1$ and $K_{s}$-band imaging data obtained with CFHT/WIRCam, we identify a sample of 56 H$α$ emission-line galaxies (ELGs) at $z=2.24$ with the 5$σ$ depths of $H_2S1=22.8$ and $K_{s}=24.8$ (AB) over 383 arcmin$^{2}$ area in the ECDFS. A detailed analysis is carried out with existing multi-wavelength data in this field. Three of the 56 H$α$ ELGs are detected in Chandra 4 Ms X-ray observation and two of them are classified as AGNs. The rest-frame UV and optical morphologies revealed by HST/ACS and WFC3 deep images show that nearly half of the H$α$ ELGs are either merging systems or with a close companion, indicating that the merging/interacting processes play a key role in regulating star formation at cosmic epoch z=2-3; About 14% are too faint to be resolved in the rest-frame UV morphology due to high dust extinction. We estimate dust extinction from SEDs. We find that dust extinction is generally correlated with H$α$ luminosity and stellar mass (SM). Our results suggest that H$α$ ELGs are representative of star-forming galaxies (SFGs). Applying extinction correction for individual objects, we examine the intrinsic H$α$ luminosity function (LF) at $z=2.24$, obtaining a best-fit Schechter function characterized by a faint-end slope of $α=-1.3$. This is shallower than the typical slope of $α\sim -1.6$ in previous works based on constant extinction correction. We demonstrate that this difference is mainly due to the different extinction corrections. The proper extinction correction is thus key to recovering the intrinsic LF as the extinction globally increases with H$α$ luminosity. Moreover, we find that our H$α$ LF mirrors the SM function of SFGs at the same cosmic epoch. This finding indeed reflects the tight correlation between SFR and SM for the SFGs, i.e., the so-called main sequence.

description: For the rendering of multiple scattering effects in participating media, methods based on the diffusion approximation are an extremely efficient alternative to Monte Carlo path tracing. However, in sufficiently transparent regions, classical diffusion approximation suffers from non-physical radiative fluxes which leads to a poor match to correct light transport. In particular, this prevents the application of classical diffusion approximation to heterogeneous media, where opaque material is embedded within transparent regions. To address this limitation, we introduce flux-limited diffusion, a technique from the astrophysics domain. This method provides a better approximation to light transport than classical diffusion approximation, particularly when applied to heterogeneous media, and hence broadens the applicability of diffusion-based techniques. We provide an algorithm for flux-limited diffusion, which is validated using the transport theory for a point light source in an infinite homogeneous medium. We further demonstrate that our implementation of flux-limited diffusion produces more accurate renderings of multiple scattering in various heterogeneous datasets than classical diffusion approximation, by comparing both methods to ground truth renderings obtained via volumetric path tracing.

description: A quantum phase transition may occur in the ground state of a system at zero temperature when a controlling field or interaction is varied. The resulting quantum fluctuations which trigger the transition produce scaling behavior of various observables, governed by universal critical exponents. A particularly interesting class of such transitions appear in systems with quantum impurities where a non-extensive term in the free energy becomes singular at the critical point. Curiously, the notion of a conventional order parameter which exhibits scaling at the critical point is generically missing in these systems. We here explore the possibility to use the Schmidt gap, which is an observable obtained from the entanglement spectrum, as an order parameter. A case study of the two-impurity Kondo model confirms that the Schmidt gap faithfully captures the scaling behavior by correctly predicting the critical exponent of the dynamically generated length scale at the critical point.

description: Evaluating a lattice path integral in terms of spectral data and matrix elements pertaining to a suitably defined quantum transfer matrix, we derive form-factor series expansions for the dynamical two-point functions of arbitrary local operators in fundamental Yang-Baxter integrable lattice models at finite temperature. The summands in the series are parameterised by solutions of the Bethe Ansatz equations associated with the eigenvalue problem of the quantum transfer matrix. We elaborate on the example of the XXZ chain for which the solutions of the Bethe Ansatz equations are sufficiently well understood in certain limiting cases. We work out in detail the case of the spin-zero operators in the antiferromagnetic massive regime at zero temperature. In this case the thermal form-factor series turn into series of multiple integrals with fully explicit integrands. These integrands factorize into an operator-dependent part, determined by the so-called Fermionic basis, and a part which we call the universal weight as it is the same for all spin-zero operators. The universal weight can be inferred from our previous work. The operator-dependent part is rather simple for the most interesting short-range operators. It is determined by two functions $ρ$ and $ω$ for which we obtain explicit expressions in the considered case. As an application we rederive the known explicit form-factor series for the two-point function of the magnetization operator and obtain analogous expressions for the magnetic current and the energy operators.

description: We estimate the fraction of F,G,K stars with close binary companions by analysing multi-epoch stellar spectra from SDSS and LAMOST for radial velocity (RV) variations. We employ a Bayesian method to infer the maximum likelihood of the fraction of binary stars with orbital periods of 1000 days or shorter, assuming a simple model distribution for a binary population with circular orbits. The overall inferred fraction of stars with such a close binary companion is 43.0% \pm 2.0% for a sample of F, G, K stars from SDSS SEGUE, and 30% \pm 8.0% in a similar sample from LAMOST. The apparent close binary fraction decreases with the stellar effective temperature. We divide the SEGUE and LEGUE data into three subsamples with different metallicity ([Fe/H] < -1.1; -1.1 < [Fe/H] < -0.6; -0.6 < [Fe/H]), for which the inferred close binary fractions are 56% \pm 5.0%, 56.0% \pm 3%, and 30% \pm 5.7%. The metal-rich stars from our sample are therefore substantially less likely to possess a close binary companion than otherwise similar stars drawn from metal-poor populations. The different ages and formation environments of the Milky Way's thin disk, thick disk and halo may contribute to explaining these observations. Alternatively metallicity may have a significant effect on the formation and/or evolution of binary stars.

description: Simulating the nonequilibrium dynamics of thermal states is a fundamental problem across scales from high energy to condensed matter physics. Quantum computers may provide a way to solve this problem efficiently. Preparing a thermal state on a quantum computer is challenging, but there exist methods to circumvent this by computing a weighted sum of time-dependent matrix elements in a convenient basis. While the number of basis states can be large, in this work we show that it can be reduced by simulating only the largest density matrix elements by weight, capturing the density matrix to a specified precision. Leveraging Hamiltonian symmetries enables further reductions. This approach paves the way to more accurate thermal-state dynamics simulations on near-term quantum hardware.

description: We study the spectral properties of two classes of random matrix models: non-Gaussian RMT with quartic and sextic potentials, and RMT with Gaussian noise. We compute and analyze the quantum Krylov complexity and the spectral form factor for both of these models. We find that both models show suppression of the spectral form factor at short times due to decoherence effects, but they differ in their long-time behavior. In particular, we show that the Krylov complexity for the non-Gaussian RMT and RMT with noise deviates from that of a Gaussian RMT. We discuss the implications and limitations of our results for quantum chaos and quantum information in open quantum systems. Our study reveals the distinct sensitivities of the spectral form factor and complexity to non-Gaussianity and noise, which contribute to the observed differences in the different time domains.

description: The derivation of determinant representations for the space-, time-, and temperature-dependent correlation functions of the impenetrable Gaudin-Yang model in the presence of a trapping potential is presented. These representations are valid in both equilibrium and nonequilibrium scenarios like the ones initiated by a sudden change of the confinement potential. In the equal-time case our results are shown to be equivalent to a multicomponent generalization of Lenard's formula from which Painlevé transcendent representations for the correlators can be obtained in the case of harmonic trapping and Dirichlet and Neumann boundary conditions. For a system in the quantum Newton's cradle setup the determinant representations allow for an exact numerical investigation of the dynamics and even hydrodynamization which is outside the reach of Generalized Hydrodynamics or other approximate methods. In the case of a sudden change in the trap's frequency we predict a many-body bounce effect, not present in the evolution of the density profile, which causes a nontrivial periodic narrowing of the momentum distribution with amplitude depending on the statistics of the particles.

description: The Ising model is defined by an objective function using a quadratic formula of qubit variables. The problem of an Ising model aims to determine the qubit values of the variables that minimize the objective function, and many optimization problems can be reduced to this problem. In this paper, we focus on optimization problems related to permutations, where the goal is to find the optimal permutation out of the $n!$ possible permutations of $n$ elements. To represent these problems as Ising models, a commonly employed approach is to use a kernel that utilizes one-hot encoding to find any one of the $n!$ permutations as the optimal solution. However, this kernel contains a large number of quadratic terms and high absolute coefficient values. The main contribution of this paper is the introduction of a novel permutation encoding technique called dual-matrix domain-wall, which significantly reduces the number of quadratic terms and the maximum absolute coefficient values in the kernel. Surprisingly, our dual-matrix domain-wall encoding reduces the quadratic term count and maximum absolute coefficient values from $n^3-n^2$ and $2n-4$ to $6n^2-12n+4$ and $2$, respectively. We also demonstrate the applicability of our encoding technique to partial permutations and Quadratic Unconstrained Binary Optimization (QUBO) models. Furthermore, we discuss a family of permutation problems that can be efficiently implemented using Ising/QUBO models with our dual-matrix domain-wall encoding.

description: Am Deutschen Archäologischen Institut (DAI) wurde ein digitaler Knotenpunkt für die zentralen Informationen für den Bereich Forschungsdatenmanagement (FDM) für die Mitarbeitenden domänenspezifisch aufgearbeitet und präsentiert. Wenige Inhalte mussten hierfür neu erstellt werden, die Herausforderung lag in der Zusammenstellung, der Les- und Nutzbarkeit sowie der Reduktion der umfangreichen Inhalte. Zur Umsetzung wurde die Software Confluence verwendet. Konzeption, Aufbau, Struktur sowie verwendete Werkzeuge werden detailliert beschrieben sowie angewandte und erprobte Vorgehensweisen, um einem Veralten der Informationen weitestgehend entgegenzuwirken und eine Wartbarkeit zu ermöglichen. Der FDM-Bereich am DAI wurde in weniger als einem Jahr aufgebaut, in diesem Artikel werden Empfehlungen zur Umsetzung und Vereinfachung gegeben.

description: We study the geodesic X-ray transform $X$ on compact Riemannian surfaces with conjugate points. Regardless of the type of the conjugate points, we show that we cannot recover the singularities and therefore, this transform is always unstable (ill-posed). We describe the microlocal kernel of $X$ and relate it to the conjugate locus. We present numerical examples illustrating the cancellation of singularities. We also show that the attenuated X-ray transform is well posed if the attenuation is positive and there are no more than two conjugate points along each geodesic; but still ill-posed, if there are three or more conjugate points. Those results follow from our analysis of the weighted X-ray transform.

Metastability and dynamics in remanent states of square artificial spin ice with long-range dipole interactions

description: After removal of an applied magnetic field, artificial square spin ice can be left in a metastable remanent state, with nonzero residual magnetization and excess energy above the ground state. Using a model of magnetic islands with dipoles of fixed magnitude and local anisotropies, the remanent states are precisely determined here, including all long-range dipole interactions. Small deviations away from remanent states are analyzed and the frequencies of modes of oscillation are determined. Some modes reach zero frequency at high symmetry wave vectors, such that the stability limits are found, as determined by the local anisotropy strength relative to the dipolar coupling strength.
Impacts of pharmaceutical pollution on wildlife in a multi-stressor world

description: This thesis examines the ecological and evolutionary effects of pharmaceutical pollutants on wildlife, in combination with stressors such as temperature and infectious disease. It demonstrates that exposure to fluoxetine, a common antidepressant pollutant, can alter reproductive traits of wildlife in a temperature-dependent manner, shift the nature of host-parasite interactions and influence the spread of disease in a population.

description: The log-rank conjecture is one of the fundamental open problems in communication complexity. It speculates that the deterministic communication complexity of any two-party function is equal to the log of the rank of its associated matrix, up to polynomial factors. Despite much research, we still know very little about this conjecture. Recently, there has been renewed interest in this conjecture and its relations to other fundamental problems in complexity theory. This survey describes some of the recent progress, and hints at potential directions for future research.

description: Background: Media campaigns increase awareness of public health programs that assist smoking cessation (e.g. telephone quitline and insurance benefits). The True Stories Campaign launched in Massachusetts (MA) from Nov-Dec 2006 promoted the use of the telephone quitline and a new Medicaid insurance benefit that provided low-cost cessation treatment as part of Health Care Reform.

Objective: We evaluated the effectiveness of the True Stories Campaign on awareness of 1) the state telephone quitline and 2) the Mass Health smoking cessation benefit among the target population and by select demographic characteristics.

Methods & Analyses: MA adults age 18-98 were surveyed at baseline (n=3,000) and 2 months later (post-campaign, n=3,000). Awareness of the quitline and MassHealth benefit prior to and post-campaign were estimated and compared using proportion tests and logistic regression models.

Results: Awareness of the quitline increased from 26.6% at baseline to 52.5% after the campaign (Odds Ratio (OR) = 3.1, p<.001). Increases were largely invariant by respondent gender (men: OR = 3.3, women: OR=2.8), race (white/non Hispanic: OR=2.9, minorities: OR=3.7), insurance status (MassHealth recipient: OR=4.3, other insurance: OR=2.8), smoking status (former: OR=2.9, nondaily: OR=3.1, daily: OR=3.9) and age group (18-44: OR=2.7, 45-64: OR=3.1, 65+: OR=5.0). The campaign also increased awareness of the MassHealth Benefit from 15.7% to 23.7% (OR=1.7, p< 0.001) across many subpopulations including gender (OR=1.7 for both gender), race (OR=1.7 for all groups), insurance status (MassHealth recipient: OR=2.0, other insurance: OR=1.6), and slightly varied among age group (18-44: OR=2.7, 45-64: OR=1.9, 65+: OR=1.6). The results were robust to whether respondents correctly recalled their exposure to the campaign.

Conclusions: The brief media campaign increased awareness of the state telephone quitline and the insurance benefit in the target population. It was effective across several demographic groups, suggesting the applicability to the general adult population and potential cost-effectiveness of a larger campaign.

description: In diesem Beitrag wird die Bedeutung der Praxislehrpersonen in der schulpraktischen Ausbildung und der Mentor:innen im Berufseinstieg in ihren Rollen und den damit verbundenen Aufgaben für die professionelle Entwicklung von Lehrpersonen untersucht. Dafür werden Daten aus zwei Forschungsprojekten an einer Pädagogischen Hochschule in der Schweiz analysiert und zueinander in Bezug gesetzt. Die Ergebnisse der beiden Studien zeigen, dass Mentoring eine Doppelfunktion hat. Es ist eine Form der Unterstützung für die Entwicklung der professionellen Kompetenzen der angehenden Lehrpersonen und eine Chance für die Weiterentwicklung der Unterrichtspraxis der Praxislehrpersonen. Mentoring in der Lehrer:innenbildung verknüpft theoretische Elemente mit praktischen Erfahrungen und ermöglicht durch unterschiedliche Perspektiven auf den Lehrberuf eine gemeinsame Reflexion, die für die professionelle Entwicklung der Lehrpersonen zentral ist.
