description: We study exact sequences of finite tensor categories of the form $\Rep G \to \C \to \D$, where $G$ is a finite group. We show that, under suitable assumptions, there exists a group $Γ$ and mutual actions by permutations $\rhd: Γ\times G \to G$ and $\lhd: Γ\times G \to Γ$ that make $(G, Γ)$ into matched pair of groups endowed with a natural crossed action on $\D$ such that $\C$ is equivalent to a certain associated crossed extension $\D^{(G, Γ)}$ of $\D$. Dually, we show that an exact sequence of finite tensor categories $\vect_G \to \C \to \D$ induces an $\Aut(G)$-grading on $\C$ whose neutral homogeneous component is a $(Z(G), Γ)$-crossed extension of a tensor subcategory of $\D$. As an application we prove that such extensions $\C$ of $\D$ are weakly group-theoretical fusion categories if and only if $\D$ is a weakly group-theoretical fusion category. In particular, we conclude that every semisolvable semisimple Hopf algebra is weakly group-theoretical.

description: Observations from the large galaxy surveys, especially the measurements of galaxy clustering and weak gravitational lensing have emerged as a strong probes of cosmology in the last decade and a half. Joint analysis of galaxy clustering and galaxy position-lensing (g-L) cross correlations provides a direct measurement of the clustering of matter in the universe and thus a strong test of models of
cosmology, independent of the galaxy bias. Combined with measurements of galaxy velocities from redshift space distortions, these measurements can also test the models of gravity

description: Monolayer transition metal dichalcogenides, known for exhibiting strong excitonic resonances, constitute a very interesting and versatile platform for investigation of light-matter interactions. In this work we report on a strong coupling regime between excitons in monolayer WSe2 and photons confined in an open, voltage-tunable dielectric microcavity. The tunability of our system allows us to extend the exciton-polariton state over a wide energy range and, in particular, to bring the excitonic component of the lower polariton mode into resonance with other excitonic transitions in monolayer WSe2. With selective excitation of spin-polarized exciton-polaritons we demonstrate the valley polarization when the polaritons from the lower branch come into resonance with a bright trion state in monolayer WSe2 and valley depolarization when they are in resonance with a dark trion state.

description: Soft x-ray fluorescence spectroscopy has been employed to obtain information about the Si-derived valence band states of Fe/Si multilayers. The valence band spectra are quite different for films with and without antiferromagnetic interlayer exchange coupling, demonstrating that these multilayers have different silicide phases in their spacer layers. Comparison with previously published fluorescence data on bulk iron silicides shows that the Fe concentration in the silicide spacer layers is substantial. Near-edge x-ray absorption data on antiferromagnetically coupled multilayers in combination with the fluorescence data demonstrate unambiguously that the silicide spacer layer in these films is metallic. These results on the electronic structure of buried layers in a multilayer film exemplify the wide range of experiments made possible by new high-brightness synchrotron sources.

description: We present an analysis of K2 short cadence data of 34 M dwarfs which have spectral types in the range M0 - L1. Of these stars, 31 showed flares with a duration between $\sim$10-90 min. Using distances obtained from Gaia DR2 parallaxes, we determined the energy of the flares to be in the range $\sim1.2\times10^{29}-6\times10^{34}$ erg. In agreement with previous studies we find rapidly rotating stars tend to show more flares, with evidence for a decline in activity in stars with rotation periods longer than $\sim$10 days. The rotational modulation seen in M dwarf stars is widely considered to result from a starspot which rotates in and out of view. Flux minimum is therefore the rotation phase where we view the main starspot close to the stellar disk center. Surprisingly, having determined the rotational phase of each flare in our study we find none show any preference for rotational phase. We outline three scenarios which could account for this unexpected finding. The relationship between rotation phase and flare rate will be explored further using data from wide surveys such as NGTS and TESS.

Dimensional perturbation theory for vibration-rotation spectra of linear triatomic molecules
Creators: name: Suvernev, Andrei A.

Year: 1997
Subjects: subject: Chemical Physics (physics.chem-ph)
subject: FOS: Physical sciences

description: A very efficient large-order perturbation theory is formulated for the nuclear motion of a linear triatomic molecule. To demonstrate the method, all of the experimentally observed rotational energies, with values of $J$ almost up to 100, for the ground and first excited vibrational states of CO$_2$ and for the ground vibrational states of N$_2$O and of OCS are calculated. All coupling between vibration and rotation is included. The perturbation expansions reported here are rapidly convergent. The perturbation parameter is $D^{-1/2}$, where $D$ is the dimensionality of space. Increasing $D$ is qualitatively similar to increasing the angular momentum quantum number $J$. Therefore, this approach is especially suited for states with high rotational excitation. The computational cost of the method scales only as $JN_v^{5/3}$, where $N_v$ is the size of the vibrational basis set.

description: Since a long time caffeine has been used in pharmaceutical and cosmetic preparations due to its favorable effects on the skin. The aim of this study was to evaluate the topical anti-inflammatory activity (carrageenan-induced paw oedema) of an ointment prepared using a methanolic extract from green beans of C. robusta via histology. Results showed that the treatment with the ointment reduced the paw oedema within 3 and 5 h post-carrageenan administration. The immunohistochemical evaluations of αSMA, Langerin and S100 gave further support to the morphological analysis. Finally, the methanolic extract from green beans of C. robusta proved to possess elevated free radical scavenger capability by DPPH assay, which may contribute to the observed anti-inflammatory activity.

description: We present the second major release of data from the SAMI Galaxy Survey. Data Release Two includes data for 1559 galaxies, about 50% of the full survey. Galaxies included have a redshift range 0.004 < z < 0.113 and a large stellar mass range 7.5 < log (M_star/M_sun) < 11.6. The core data for each galaxy consist of two primary spectral cubes covering the blue and red optical wavelength ranges. For each primary cube we also provide three spatially binned spectral cubes and a set of standardised aperture spectra. For each core data product we provide a set of value-added data products. This includes all emission line value-added products from Data Release One, expanded to the larger sample. In addition we include stellar kinematic and stellar population value-added products derived from absorption line measurements. The data are provided online through Australian Astronomical Optics' Data Central. We illustrate the potential of this release by presenting the distribution of ~350,000 stellar velocity dispersion measurements from individual spaxels as a function of R/R_e, divided in four galaxy mass bins. In the highest stellar mass bin (log (M_star/M_sun)>11), the velocity dispersion strongly increases towards the centre, whereas below log (M_star/M_sun)<10 we find no evidence for a clear increase in the central velocity dispersion. This suggests a transition mass around log (M_star/M_sun) ~10 for galaxies with or without a dispersion-dominated bulge.

6 + 1 Vacua in Supersymmetric QCD with G_2 Gauge Group

Year: 1998
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We consider N=1 supersymmetric QCD based on the G_2 gauge group and including 3 chiral matter 7-plets. In that case, the gauge symmetry is broken completely and the instanton-generated superpotential on the classical moduli space is present. If the theory involves the Yukawa term, there are six chirally asymmetric vacua. In the limit when the Yukawa coupling vanishes, two of the vacua run away to infinity and only 4 asymmetric vacuum states are left. Besides, a chirally symmetric state is always present. We consider also an O(7) model with 4 chiral multiplets in spinor representation. In that case, there are 4 extra "virtual vacua" dwelling at infinity of the moduli space. In a non-renormalizable theory involving a quartic term in the superpotential, they show up at finite moduli values.

Year: 2019

description: This paper investigates the influences of the recording/reproduction format, video and listening position on the quality perception of surround ambience recordings for sport events. Two microphone systems First Order Ambisonics (FOA) and Equal Segment Microphone Array (ESMA) were compared in both 4-channel (2D) and 8- channel (3D) loudspeaker reproductions. One subject group tested audio-only conditions while the other group was presented with video as well as audio. Overall, the ESMA was rated significantly higher than the FOA for all quality attributes tested regardless of the presence of video. The 2D and 3D reproductions did not have a significant difference within each microphone system. Video had a significant interaction with the microphone system and listening position depending on the attribute.

description: We study electron dynamics in a two-band delta-doped semiconductor within the envelope-function approximation. Using a simple parametrization of the confining potential arising from the ionized donors in the delta-doping layer, we are able to find exact solutions of the Dirac-type equation describing the coupling of host bands. As an application we then consider Si delta-doped GaAs. In particular we find that the ground subband energy scales as a power law of the Si concentration per unit area in a wide range of doping levels. In addition, the coupling of host bands leads to a depression of the subband energy due to nonparabolicity effects.

description: The Photon-Ion Spectrometer at PETRA III - in short, PIPE - is a permanently installed user facility at the "Variable Polarization XUV Beamline" P04 of the synchrotron light source PETRA III operated by DESY in Hamburg, Germany. The careful design of the PIPE ion-optics in combination with the record-high photon flux at P04 has lead to a breakthrough in experimental studies of photon interactions with ionized small quantum systems. This short review provides an overview over the published scientific results from photon-ion merged-beams experiments at PIPE that were obtained since the start of P04 operations in 2013. The topics covered comprise photoionization of ions of astrophysical relevance, quantitative studies of multi-electron processes upon inner-shell photoexcitation and photoionization of negative and positive atomic ions, precision spectroscopy of photoionization resonances, photoionization and photofragmentation of molecular ions and of endohedral fullerene ions.

description: We present CO J=4-3 line and 3 mm dust continuum observations of a 100 kpc-scale filamentary Lyα nebula (SSA22 LAB18) at z=3.1 using the Atacama Large Millimeter/submillimeter Array (ALMA). We detected the CO J=4-3 line at a systemic z(CO)=3.093 {\pm} 0.001 at 11 σ from one of the ALMA continuum sources associated with the Lyα filament. We estimated the CO J=4-3 luminosity of L'CO(4-3)=(2.3\pm0.2)x10^9 K km s^{-1} pc^2 for this CO source, which is one order of magnitude smaller than those of typical z>1 dusty star-forming galaxies (DSFGs) of similar far-infrared luminosity L(IR)~10^{12} Lsun. We derived a molecular gas mass of Mgas=(4.4^{+0.9}_{-0.6})x10^9 Msun and a star-formation rate of SFR=270\pm160 Msun yr^{-1}. We also estimated a gas depletion time of τ(dep)=17\pm10 Myr, being shorter than those of typical DSFGs. It is suggested that this source is in a transition phase from DSFG to a gas-poor, early-type galaxy. From ALMA to Herschel multi-band dust continuum observations, we measured a dust emissivity index β=2.3\pm0.2, which is similar to those of local gas-poor, early-type galaxies. Such a high β can be reproduced by specific chemical compositions for interstellar dust at the submillimeter wavelengths from recent laboratory experiments. ALMA CO and multi-band dust continuum observations can constrain the evolutionary stage of high-redshift galaxies through τ(dep) and β, and thus we can investigate dust chemical compositions even in the early Universe.

description: Objective: Patients’ perceptions about their asthma can influence behavior, coping and outcomes. Previous studies have also identified that patients’ views can differ significantly to that of healthcare professionals. Enhancing current understanding of patients’ perceptions can assist in reducing this mismatch. We aimed to utilize the medium of drawings to add qualitative specificity and depth to a quantitative measure of illness perceptions exploring patients’ perspectives of their asthma. Methods: Eighteen adults with asthma completed the Brief Illness Perception Questionnaire (BIPQ) and participated in a drawing activity. Analysis was based on the participants’ transcribed descriptions of their drawing. A coding approach was used to map the data according to the BIPQ items. Results: The drawings and subsequent discussions specified the “what,” the “how,” and the “why” of the experience of living with asthma. Prominent emotional and social elements emerged, with evocative images coupled with expressive and profound language. Use of drawing also revealed additional representations which were outside of the BIPQ scope. Conclusions: Using qualitative methods to analyze a novel approach to understanding illness perceptions provided insight into how asthma affects patients’ lives personally.

description: The nonlocal problems have been used to model very different applied scientific phenomena, which involve the fractional Laplacian when one looks at the Lévy processes and stochastic interfaces. This paper deals with the nonlocal problems on a bounded domain, where the stiffness matrices of the resulting systems are Toeplitz-plus-tridiagonal and far from being diagonally dominant, as it occurs when dealing with linear finite element approximations. By exploiting a weakly diagonally dominant Toeplitz property of the stiffness matrices, the optimal convergence of the two-grid method is well established [Fiorentino and Serra-Capizzano, {\em SIAM J. Sci. Comput.}, {17} (1996), pp. 1068--1081; Chen and Deng, {\em SIAM J. Matrix Anal. Appl.}, {38} (2017), pp. 869--890]; and there are still questions about best ways to define coarsening and interpolation operator when the stiffness matrix is far from being weakly diagonally dominant [Stüben, {\em J. Comput. Appl. Math.}, {128} (2001), pp. 281--309]. In this work, using spectral indications from our analysis of the involved matrices, the simple (traditional) restriction operator and prolongation operator are employed in order to handle general algebraic systems which are {\em neither Toeplitz nor weakly diagonally dominant} corresponding to the fractional Laplacian kernel and the constant kernel, respectively. We focus our efforts on providing the detailed proof of the convergence of the two-grid method for such situations. Moreover, the convergence of the full multigrid is also discussed with the constant kernel. The numerical experiments are performed to verify the convergence with only $\mathcal{O}(N \mbox{log} N)$ complexity by the fast Fourier transform, where $N$ is the number of the grid points.

X-ray spectral variability of blazars using principal component analysis

description: Principal Component Analysis (PCA) is applied to a variety of blazars to examine X-ray spectral variability. Data from nine different objects are analysed in two ways: long-term, which examines variability trends across years or decades, and short-term, which looks at variability within a single observation. The results are then compared to simulated spectra in order to identify the physical components that they correspond to. It is found that long-term variability for all objects is dominated by changes in a single power law component. The primary component is responsible for more than 84 per cent of the variability in every object, while the second component is responsible for at least 3 per cent. Small differences in the shapes of these components can be used to predict qualities such as the degree to which spectral parameters are varying relative to one another, and correlations between spectral hardness and flux. Short-term variability is less clear-cut, with no obvious physical analogue for some of the PCA results. We discuss the simulation process, and specifically remark on the consequences of the breakdown of the linearity assumption of PCA and how it manifests in the real data. We conclude that PCA is a useful tool for analysing variability, but only if its underlying assumptions and limitations are understood.

description: Background: Metastatic papillary renal cell carcinoma (mPRCC) is understudied. The disease is often aggressive and specific treatment options are lacking. Patients and methods: mPRCC patients (n = 86) referred to three academic centres in Sweden and Germany in the years 2005–2015 were retrospectively identified from medical records. Statistical analyses included Kaplan–Meier curves and calculation of Cox proportional hazards, generating hazard ratios with 95% confidence intervals. The aim of the study was to evaluate overall survival (OS) of mPRCC patients treated outside of clinical trials in the era of targeted agents (TA) and to identify clinically useful prognostic factors. Results: Median OS of all mPRCC patients was 11.2 months. TA were used in 77% of the patients and associated with younger age and better Eastern Cooperative Oncology Group performance status (PS). Brain metastases were common (28%). Patients with synchronous or metachronous metastases had similar OS. Variables independently associated with risk of death included age ≥60 years, worse PS and ≥3 metastatic sites. The MSKCC criteria did not provide additional prognostic information. A subgroup analysis of TA-treated patients revealed an association of lymph node metastasis with risk of death in addition to the other prognostic factors. Conclusion: OS in mPRCC remained short in the era of targeted agents. Age, PS, and number of metastatic sites provided independent prognostic information.

description: We explore a model akin to axion electrodynamics in which the axion field $θ(t,\mathbf{x})$ rather than being dynamical is a piecewise constant effective parameter $θ$ encoding the microscopic properties of the medium inasmuch as its permittivity or permeability, defining what we call a $θ$-medium. This model describes a large class of phenomena, among which we highlight the electromagnetic response of materials with topological order, like topological insulators for example. We pursue a Green's function formulation of what amounts to typical boundary-value problems of $θ$-media, when external sources or boundary conditions are given. As an illustration of our methods, which we have also extended to ponderable media, we interpret the constant $θ$ as a novel topological property of vacuum, a so called $θ$-vacuum, and restrict our discussion to the cases where the permittivity and the permeability of the media is one. In this way we concentrate upon the effects of the additional $θ$ coupling which induce remarkable magnetoelectric effects. The issue of boundary conditions for electromagnetic radiation is crucial for the occurrence of the Casimir effect, therefore we apply the methods described above as an alternative way to approach the modifications to the Casimir effect by the inclusion of topological insulators.
