description: The galaxy SDSSJ0952+2143 showed remarkable emission-line properties first reported in 2008 (paper I), which are the consequence of a powerful high-energy flare. Here we report follow-up observations of SDSSJ0952+2143, and discuss outburst scenarios in terms of stellar tidal disruption by a SMBH, peculiar variability of an AGN, and a supernova explosion. The optical spectrum of SDSSJ0952+2143 exhibits several peculiarities: an exceptional ratio of [FeVII] transitions over [OIII], a dramatic decrease by a factor of 10 of the highest-ionization lines, a very unusual and variable Balmer line profile including a triple-peaked narrow component with two unresolved horns, and a large Balmer decrement. The MIR emission measured with the Spitzer IRS in the narrow 10-20mu band is extraordinarily luminous (3.5 x 10^{43} erg\s). The IRS spectrum shows a bump around ~11mu and an increase towards longer wavelengths, reminiscent of silicate emission. The strong MIR excess over the NIR implies the dominance of relatively cold dust. The X-ray luminosity of 10^{41} erg\s measured with Chandra is below that typically observed in AGN. Similarities of SDSSJ0952+2143 with some extreme supernovae suggest the explosion of a supernova of Type IIn. However, an extreme accretion event in a low-luminosity AGN or inactive galaxy, especially stellar tidal disruption, remain possibilities, which could potentially produce a very similar emission-line response. If indeed a supernova, SDSSJ0952+2143 is one of the most distant X-ray and MIR detected SNe known so far, the most MIR luminous, and one of the most X-ray luminous. It is also by far the most luminous (>10^{40} erg\s) in high-ionization coronal lines, exceeding previous SNe by at least a factor of 100 [abridged].

description: Reumatoidartriit on krooniline süsteemne põletikuline haigus, mis haarab peamiselt liigeseid ja võib viia nende destruktsioonini. Haiguse  seroloogiline diagnostika on  siiani olnud piiratud  ja mittespetsiifiline. Kuna nüüdisaegse reumatoidartriidi ravi põhimõtteks on võimalikult varajane agressiivne ravi haiguse algstaadiumis, siis on suure spetsiifilisusega diagnostiliste testide kasutuselevõtt väga vajalik. Artiklis on käsitletud  tsüklilise  tsitrullineeritud peptiidi vastaste antikehade olemust, määramise metoodikat ning nende tähtsust reumatoidartriidi seroloogilises diagnostikas ja haiguse kulu hindamisel.

description: We present an implicit-explicit finite volume scheme for two-fluid single-temperature flow in all Mach number regimes which is based on a symmetric hyperbolic thermodynamically compatible description of the fluid flow. The scheme is stable for large time steps controlled by the interface transport and is computational efficient due to a linear implicit character. The latter is achieved by linearizing along constant reference states given by the asymptotic analysis of the single-temperature model. Thus, the use of a stiffly accurate IMEX Runge Kutta time integration and the centered treatment of pressure based quantities provably guarantee the asymptotic preserving property of the scheme for weakly compressible Euler equations with variable volume fraction. The properties of the first and second order scheme are validated by several numerical test cases.
Network dynamical stability analysis reveals key "mallostatic" natural variables that erode homeostasis and drive age-related decline of health

description: Using longitudinal study data, we dynamically model how aging affects homeostasis in both mice and humans. We operationalize homeostasis as a multivariate mean-reverting stochastic process. We hypothesize that biomarkers have stable equilibrium values, but that deviations from equilibrium of each biomarker affects other biomarkers through an interaction network - this precludes univariate analysis. We therefore looked for age-related changes to homeostasis using dynamic network stability analysis, which transforms observed biomarker data into independent "natural" variables and determines their associated recovery rates. Most natural variables remained near equilibrium and were essentially constant in time. A small number of natural variables were unable to equilibrate due to a gradual drift with age in their homeostatic equilibrium, i.e. allostasis. This drift caused them to accumulate over the lifespan course and makes them natural aging variables. Their rate of accumulation was correlated with risk of adverse outcomes: death or dementia onset. We call this tendency for aging organisms to drift towards an equilibrium position of ever-worsening health "mallostasis". We demonstrate that the effects of mallostasis on observed biomarkers are spread out through the interaction network. This could provide a redundancy mechanism to preserve functioning until multi-system dysfunction emerges at advanced ages.

description: We present the measurements of sky surface brightness on Mount Graham International Observatory obtained during the first binocular-mode science runs at the Large Binocular Telescope (LBT). A total of 860 images obtained on 23 moonless nights in the period Feb 2008-Jun 2008 were analyzed with our data quality assessment procedure. These data, taken at the solar minimum, show that Mt.Graham, in photometric conditions, still has one of the darkest skies, competing with the other first-class observatories. The zenith-corrected values are 21.98, 22.81, 21.81, 20.82 and 19.78 mag/arcsec^2 in U, B, V R and I, respectively. In photometric conditions, the sky background is ~0.1 mag/arcsec^2 higher than the median when observing toward Tucson and Phoenix but it may be up to ~0.5 mag/arcsec^2 higher in non-photometric conditions. The sky at Mt.Graham is ~0.32 mag/arcsec^2 brighter at airmass ~1.4 than at zenith but no significant trend was found with the time of the night. We demonstrated the dependence of the sky background at Mt.Graham on the solar activity for the first time. In fact in 2008, at B and V bands, the sky was ~0.3 mag /arcsec^2 darker than in 1999-2002. With these results we conclude that Mt.Graham is still a first-class observing site, comparable to the darkest sites in Hawaii, Chile and Canary Islands.

description: Modified theories of gravity encompass a class of $f(R)$-models that seek to elucidate the observed late time accelerated expansion of the universe. In this study, we examine a set of viable $f(R)$ models (Hu-Sawicki: two cases, Satrobinsky, Tsujikawa, exponential and arcTanh models) in metric formalism, using recent cosmological data sets: type Ia supernovae data, cosmic chronometer observations, baryonic acoustic oscillations data, data from H\textsc{ii} starburst galaxies, and local measurements of the Hubble parameter $H_0$. The model parameters are constrained using a Bayesian analysis with the Monte Carlo Markov Chain method. We employ statistical tools such as the Akaike Information Criterion, Bayesian Information Criterion, and reduced chi-square statistics to conduct a comparative investigation of these models. We determine the transition redshift, the evolution of total equation-of-state (EoS) parameter, and the EoS for the component responsible for current accelerated expansion to characterize the expansion's evolution. Taking into account the ``Hubble tension," we perform the study with and without a Gaussian prior for $H_0$ from local measurements. Our findings are as follows: (i) in many cases the $f(R)$ models are strongly favored over the standard $Λ$CDM model, (ii) the deviation parameter ($b$) significantly deviates from zero in several cases, (iii) the inclusion of local $H_0$ not only increases the fitted value of $H_0$ (as expected) but also affects the gap between predictions of $f(R)$ models and the $Λ$CDM model, and (iv) the relevant quantities characterizing the (accelerated) expansion of the universe obtained in our models are consistent with those obtained in a model-independent way by others. Our investigation and results present a compelling case for pursuing further research on $f(R)$ models with future observations to come.
Automorphisms of extensions of Lie-Yamaguti algebras and Inducibility problem

description: Lie-Yamaguti algebras generalize both the notions of Lie algebras and Lie triple systems. In this paper, we consider the inducibility problem for automorphisms of extensions of Lie-Yamaguti algebras. More precisely, given an abelian extension $$0 \to V \xrightarrow[]{i} \widetilde{L} \xrightarrow[]{p} L \to 0$$ of a Lie-Yamaguti algebra $L$, we are interested in finding the pairs $(ϕ, ψ)\in \mathrm{Aut}(V)\times \mathrm{Aut}(L)$, which are inducible by an automorphism in $\mathrm{Aut}(\widetilde{L})$. We connect the inducibility problem to the $(2,3)$-cohomology of Lie-Yamaguti algebra. In particular, we show that the obstruction for a pair of automorphism in $\mathrm{Aut}(V)\times \mathrm{Aut}(L)$ to be inducible lies in the $(2,3)$-cohomology group $\mathrm{H}^{(2,3)}(L,V)$. We develop the Wells exact sequence for Lie-Yamaguti algebra extensions, which relates the space of derivations, automorphism groups, and $(2,3)$-cohomology groups of Lie-Yamaguti algebras. As an application, we describe certain automorphism groups of semi-direct product Lie-Yamaguti algebras. In the sequel, we apply our results to discuss inducibility problem for nilpotent Lie-Yamaguti algebras of index $2$. We give examples of infinite families of such nilpotent Lie-Yamaguti algebras and characterize the inducible pairs of automorphisms for extensions arising from these examples. Finally, we write an algorithm to find out all the inducible pairs of automorphisms for extensions arising from nilpotent Lie-Yamaguti algebras of index $2$.

description: In two-dimensional electron systems, plasmons are gapless and long-lived collective excitations of propagating charge density oscillations. We study the fluctuation mechanism of plasmon-assisted transport in the regime of electron hydrodynamics. We consider pristine electron liquids where charge fluctuations are thermally induced by viscous stresses and intrinsic currents, while attenuation of plasmons is determined by the Maxwell mechanism of charge relaxation. We show that while the contribution of plasmons to the shear viscosity and thermal conductivity of a Fermi liquid is small, plasmon resonances in the bilayer devices enhance the drag resistance. In systems without Galilean invariance, fluctuation-driven contributions to dissipative coefficients can be described only in terms of hydrodynamic quantities: intrinsic conductivity, viscosity, and plasmon dispersion relation.

description: The conversion between different spherical image and video projection formats requires highly accurate resampling techniques in order to minimize the inevitable loss of information. Suitable resampling algorithms such as nearest neighbor, linear or cubic resampling are readily available. However, no generally applicable resampling technique exploits the special properties of spherical images so far. Thus, we propose a novel viewport-adaptive resampling (VAR) technique that takes the spherical characteristics of the underlying resampling problem into account. VAR can be applied to any mesh-to-mesh capable resampling algorithm and shows significant gains across all tested techniques. In combination with frequency-selective resampling, VAR outperforms conventional cubic resampling by more than 2 dB in terms of WS-PSNR. A visual inspection and the evaluation of further metrics such as PSNR and SSIM support the positive results.

Christopher Boorse’i analüütiline terviseteooria vaatleb tervist ja tõbe organismi tasandil. Selle biostatistilise teooria lähtemõiste on tõbi (ingl disease) ning tervise hindamise aluseks liigiomase bioloogilise funktsiooni statistiline norm. Lennart Nordenfelti normatiivne terviseteooria vaatleb isiku tervist velfaristlikus tegevusteoreetilises raamistikus. Teooria primaarmõiste on tervis ning selle hindamise aluseks on inimese enese hinnang oluliseks peetud eesmärkide saavutatuse kohta.

description: Motion compensation is one of the key technologies enabling the high compression efficiency of modern video coding standards. To allow compression of spherical video content, special mapping functions are required to project the video to the 2D image plane. Distortions inevitably occurring in these mappings impair the performance of classical motion models. In this paper, we propose a novel motion plane adaptive motion modeling technique (MPA) for spherical video that allows to perform motion compensation on different motion planes in 3D space instead of having to work on the - in theory arbitrarily mapped - 2D image representation directly. The integration of MPA into the state-of-the-art H.266/VVC video coding standard shows average Bjøntegaard Delta rate savings of 1.72\% with a peak of 3.37\% based on PSNR and 1.55\% with a peak of 2.92\% based on WS-PSNR compared to VTM-14.2.

description: One of the foundations of the Standard Model of Cosmology is statistical isotropy, which can be tested, among other probes, through the study of the Cosmic Microwave Background (CMB). However, a hemispherical power asymmetry on large scales has been reported for WMAP and Planck data by different works. The statistical significance is above 3$σ$ for temperature, suggesting a directional dependence of the local power spectrum, and thus a feature beyond the $Λ$CDM model. With the third release of the Planck data (PR3), a new analysis was performed including the E-mode polarization maps, finding an asymmetry at a modest level of significance. In this work, we perform an asymmetry analysis in intensity and polarization maps for the latest Planck processing pipeline (PR4). We obtain similar results to those obtained with PR3, with a slightly lower significance (2.8% for the Sevem method) for the amplitude of the E-mode local variance dipole as well as a significant variability with the considered mask. In addition, a hint of a possible T-E alignment between the asymmetry axes is found at the level of $\sim$ 5%. For the analysis, we have implemented an alternative inpainting approach in order to get an accurate reconstruction of the E-modes. More sensitive all-sky CMB polarization data, such as those expected from the future LiteBIRD experiment, are needed to reach a more robust conclusion on the possible existence of deviations from statistical isotropy in the form of a hemispherical power asymmetry.

description: Using the results of extensive Monte Carlo simulations we discuss corrections to the linear mixing rule in strongly coupled binary ionic mixtures. We analyze the plasma screening function at zero separation, H_{jk}(0), for two ions (of types j=1,2 and k=1,2) in a strongly coupled binary mixture. The function H_{jk}(0) is estimated by two methods: (1) from the difference of Helmholtz Coulomb free energies at large and zero separations; (2) by fitting the Widom expansion of H_{jk}(x) in powers of interionic distance x to Monte Carlo data on the radial pair distribution function g_{jk}(x). These methods are shown to be in good agreement. For illustration, we analyze the plasma screening enhancement of nuclear burning rates in dense stellar matter.

It is found that thicknesses as low as 0.5 A can be monitored to within ± 5%. An attempt is made to improve the structure of the gold films by using rapid deposition rates (15 to 20 A per second) and by depositing the gold films on nucleating silver layers of molecular thicknesses. The effect of increasing nucleating layer thicknesses (up to 25 A) is studied by electron microscopy and d.c. resistance measurements. A critical nucleating layer thickness for silver is found to exist between 5 to 7 A. On these critical layers, gold films down to 25 A are found conducting. All the films tested show an irreversible change in conductivity with heating. Without a silver layer, continuous decrease in the conductivity of gold films is observed, the film being destroyed at 450° C. On the other hand, increasingly better conductivities are observed by heating the gold-on-silver films, and an optimum annealing temperature of about 350° C is indicated. Above this temperature the conductivity decreases; however, films are still conducting and continuous at 600° C. These films are, therefore, suitable as heat reflecting windows. D.C, and high frequency measurements (at 9.7 Gc) on gold films are given. In both cases, almost identical values of surface resistance are obtained in the range 10 to 1,000 ohms per square. A method for preparing gold film bolometer elements using interrupted deposition of gold on a nucleating silver layer is discussed. As very thin gold on silver films with high d.c. conductivities are found to have low microwave transmission coefficients, the possible application of visual protection from microwave radiation is discussed.

description: Pankrease pseudotsust on ägeda ja kroonilise pankreatiidi või pankreasetrauma üks võimalikke tüsistusi. Pankrease pseudotsust on amulaasi ja teiste pankrease ensüümide suure sisaldusega lokaliseerunud vedelikukogumik, mis on ümbritsetud fibrooskoelise seinaga ning mida ei vooderda epiteel (1).Pseudotsustid on ühenduses pankreasejuha süsteemiga kas otseselt või pankrease parenhuumi kaudu. Tekkepõhjuseks peetakse pankreasejuha rebenemist suurenenud surve tõttu, mille põhjuseks võib olla juha stenoos, juha ummistavad kivid või proteiinikämbud ning ägedast pankreatiidist tingitud pankreasenekroos (2, 3). Harva võivad pankrease pseudotsüstid laieneda ka keskseinandisse (4, 5). Sellisel juhul võivad nad tekitada pleura või perikardi efusiooni, kuid samuti võivad nad massiefekti tõttu põhjustada ka südame kompressiooni ning düsfaagiat (6, 7). Pankrease pseudotsustiga seoses on kirjeldatud ka väga harva esinevaid haigusjuhtumeid nagu pseudotsüsti ruptuuri portaalveeni (8), pseudotsüsti paiknemist alajäseme lihaste vahel kuni põlveõndlani (9) ning pseudotsüstist tingitud ülemise mesenteriaalarteri erosiooni ja sellest lähtunud seedetraktiverejooksu (10). Artikli kirjutamise ajendiks sai asjaolu, et mediastinaalsed pankreasest ürgnenud pseudotsustid on väga harvaks nähtuseks kogu maailmas. Pankrease pseudotsusti ruptuurist tingitud mediastiniiti on aga meile teadaolevatel andmetel varem kirjeldatud vaid väga üksikutel juhtudel.

title: Weir-Baffled Culvert Hydrodynamics Evaluation for Fish Passage Using Particle Image Velocimetry and Computational Fluid Dynamic Techniques
Creators: name: Khodier, Mohanad A.
Publisher: name: Utah State University
Year: 2014

description: Due to a recent increase in environmental awareness regarding fish passage through hydraulic constructions including culverts, an evaluation for the passage of wild brown trout through a weir-baffled prototype-scale culvert was performed under a variety of culvert slopes and discharge conditions. The influence of the sample fish population and the length of the individual fish on passage rates were investigated; the data showed that the brown trout fish passage sample size evaluated in this study (25 per test) was sufficiently large to minimize sample size dependency. Fish behavior while traversing the culvert was observed and reported, including resting/staging zone locations.
Turbulent flow through weir baffled-culvert was also simulated numerically using three-dimensional numerical model employing the (k-Є) model, Renormalized Group k-Є model (RNG), and Large Eddy Simulation (LES) model. Experimental data measured with the Particle Image Velocimetry (PIV) were used to assess the accuracy and the applicability of these turbulence models in predicting the turbulent flow characteristics of the flow through a weir-baffled culvert at different spatial locations inside the culvert for variety of culvert slopes and flow rates. The influence of flow rates and culvert slopes on the forward velocities and reverse velocities was evaluated. It was noted that the influence of the flow rates on the flow velocities depends on the culvert slopes. Turbulent kinetic energy and flow direction effects on flow characteristic were also evaluated. Validation of Manning’s equation and Manning’s roughness coefficient for the tested culvert were reported.

description: We investigate the process $η_c \to {\bar{K}}^0K^+π^-$ by taking into account the $S$-wave ${K^*\bar{K}^*}$ and $ρω$ interactions within the unitary coupled-channel approach, where the scalar meson $a_0(1710)$ is dynamically generated. In addition, the contributions from the intermediate resonances $K_0^*(1430)^{-}\to {\bar{K}}^0π^- $ and $K_0^*(1430)^{0}\to K^+π^-$ are also considered. We find a significant dip structure around 1.8~GeV, associated to the $a_0(1710)$, in the ${\bar{K}^0K^+}$ invariant mass distribution, and the clear peaks of the $K_0^*(1430)$ in the ${\bar{K}}^0π^-$ and $K^+π^-$ invariant mass distributions, consistent with the {\it BABAR} measurements. We further estimate the branching fractions $\mathcal{B}(η_c \to \bar{K}^{*0}K^{\ast+}π^-)= 5.5\times10^{-3}$ and $\mathcal{B}(η_c \to ωρ^+π^-)= 7.9\times10^{-3}$. Our predictions can be tested by the BESIII and BelleII experiments in the future.

description: The Covid-19 pandemic has changed the way work is conducted resulted in widespread unemployment–both of which may have consequences for workers’ wellbeing. Using unique data collected during New Zealand’s Alert Level 4 lockdown, this paper examines differences in affective wellbeing among surveyed workers (n = 1,238) who lost jobs due to the lockdown and those who remained employed. We found that those who lost jobs, compared to those who remained employed, experienced poorer wellbeing. Essential workers also experienced more stress and worry than other workers. The findings can inform policy aimed at buffering workers from the negative consequence of pandemic-related restrictions.
A study of the nucleate boiling heat transfer coefficient of dichlorodifluoremethane (Freon-12) over a horizontal surface
Creators: name: Tang, Shih-I
Publisher: name: University of British Columbia
Year: 2011

description: The heat transfer coefficients for oil-free liquid dichlorodifluoromethane (Preon-12 or Genetron-12) in nucleate boiling over a horizontal copper surface were measured at saturation temperatures of 0°F and 25°F and at heat flux densities between 6,000 and 63,000 Btu/hr-ft². The heating surfaces were finished with 400-A emery paper in two different patterns before each series of test-runs, while the geometric arrangement and the other parameters of the apparatus remained unchanged. Profilometer measurements of roughness and photomicrographs of the surface were taken. All the boiling curves calculated and plotted from the experimental results were of "S" shape, revealing a pronounced deviation from the conventional (normal) boiling curve, especially at lower saturation temperatures. The deviation of the boiling curve was probably due to the unpredictable nucleating characteristics of the heating surface and of the bubble population [1, 2]. This makes it impossible to correlate the experimental data by any of the existing empirical equations formulated by Zuber [3, 4, 5], Rohsenow [6, 7], Levy [16] and others.
Approximate Inference via Fibrations of Statistical Games

description: We characterize a number of well known systems of approximate inference as loss models: lax sections of 2-fibrations of statistical games, constructed by attaching internally-defined loss functions to Bayesian lenses. Our examples include the relative entropy, which constitutes a strict section, and whose chain rule is formalized by the horizontal composition of the 2-fibration. In order to capture this compositional structure, we first introduce the notion of 'copy-composition', alongside corresponding bicategories through which the composition of copy-discard categories factorizes. These bicategories are a variant of the Copara construction, and so we additionally introduce coparameterized Bayesian lenses, proving that coparameterized Bayesian updates compose optically, as in the non-coparameterized case.

description: A new network model is proposed to describe the $1/f^α$ resistance noise in disordered materials for a wide range of $α$ values ($0< α< 2$). More precisely, we have considered the resistance fluctuations of a thin resistor with granular structure in different stationary states: from nearly equilibrium up to far from equilibrium conditions. This system has been modelled as a network made by different species of resistors, distinguished by their resistances, temperature coefficients and by the energies associated with thermally activated processes of breaking and recovery. The correlation behavior of the resistance fluctuations is analyzed as a function of the temperature and applied current, in both the frequency and time domains. For the noise frequency exponent, the model provides $0< α< 1$ at low currents, in the Ohmic regime, with $α$ decreasing inversely with the temperature, and $1< α<2$ at high currents, in the non-Ohmic regime. Since the threshold current associated with the onset of nonlinearity also depends on the temperature, the proposed model qualitatively accounts for the complicate behavior of $α$ versus temperature and current observed in many experiments. Correspondingly, in the time domain, the auto-correlation function of the resistance fluctuations displays a variety of behaviors which are tuned by the external conditions.

description: In one-dimensional quantum lattice models with open boundaries, we find and study localization at the lattice edge. We show that edge-localized eigenstates can be found in both bosonic and fermionic systems, specifically, in the Bose-Hubbard model with on-site interactions and in the spinless fermion model with nearest-neighbor interactions. We characterize the localization through spectral studies via numerical diagonalization and perturbation theory, through considerations of the eigenfunctions, and through the study of explicit time evolution. We concentrate on few-particle systems, showing how more complicated edge states appear as the number of particles is increased.

title: A Study of the Inheritance and Linkage Relationships of Three Glossy Characteristics in Barley
Creators: name: Martineau, Jess R.
Publisher: name: Utah State University
Year: 1972

description: Twenty-two barley crosses (Hordeum sp.) were studied in the F2 generation to determine the inheritance of the following contrasting characters: (N,n),(E,e),(Tr, tr), (Li,li),(Gp,gp),(K,k),(Z,z), (Gl,gl), (Gs, gs),(B,b),(Trd,trd),(O,o),(R,r),(Rb,rb), and Ge, ge).
The three factors for glossyness, (gl), (gs), and (ge), were studied in relation to the other factors and each other to determine possible linkage relationships.
(gl) was found to be linked with (k) and 16 percent recombination and to (z) with 13 percent recombination. (gs) appeared to be linked with (gp) in two crosses, with a third cross showing independence. No other linkage relationships were found.
A closed form exact formulation of the spectral representation of a second-order symmetric tensor and of its derivatives

description: The spectral decomposition of a symmetric, second-order tensor is widely adopted in many fields of Computational Mechanics. As an example, in elasto-plasticity under large strain and rotations, given the Cauchy deformation tensor, it is a fundamental step to compute the logarithmic strain tensor.
 Recently, this approach has been also adopted in small-strain isotropic plasticity to reconstruct the stress tensor as a function of its eigenvalues, allowing the formulation of predictor-corrector return algorithms in the invariants space. These algorithms not only reduce the number of unknowns at the constitutive level, but also allow the correct handling of stress states in which the plastic normals are undefined, thus ensuring a better convergence with respect to the standard approach.
 While the eigenvalues of a symmetric, second-order tensor can be simply computed as a function of the tensor invariants, the computation of its eigenbasis can be more difficult, especially when two or more eigenvalues are coincident. Moreover, when a Newton-Rhapson algorithm is adopted to solve nonlinear problems in Computational Mechanics, also the tensorial derivatives of the eigenbasis, whose computation is still more complicate, are required to assemble the tangent matrix.
 A simple and comprehensive method is presented, which can be adopted to compute a closed form representation of a second-order tensor, as well as their derivatives with respect to the tensor itself, allowing a simpler implementation of spectral decomposition of a tensor in Computational Mechanics applications.

description: Our adaptive optics observations of nearby AGN at spatial resolutions as small as 0.085arcsec show strong evidence for recent, but no longer active, nuclear star formation. We begin by describing observations that highlight two contrasting methods by which gas can flow into the central tens of parsecs. Gas accumulation in this region will inevitably lead to a starburst, and we discuss the evidence for such events. We then turn to the impact of stellar evolution on the further inflow of gas by combining a phenomenological approach with analytical modelling and hydrodynamic simulations. These complementary perspectives paint a picture in which all the processes are ultimately regulated by the mass accretion rate into the central hundred parsecs, and the ensuing starburst that occurs there. The resulting supernovae delay accretion by generating a starburst wind, which leaves behind a clumpy interstellar medium. This provides an ideal environment for slower stellar outflows to accrete inwards and form a dense turbulent disk on scales of a few parsecs. Such a scenario may resolve the discrepancy between the larger scale structure seen with adaptive optics and the small scale structure seen with VLTI.
