description: This presentation describes two initiatives aimed at enhancing FAIRification of sample data. One is being undertaken by SciLifeLab Data Centre. In conjunction with instating the infrastructure to allow handling of biospecimens in life sciences, associated metadata and datasets, we hope to mobilize the community to identify the minimum set of attributes required for describing biospecimens in biological life science (Minimal Information About a Biological Sample, MIABS) with ontological mapping for semantic unambiguity and machine actionability. The aim is to facilitate the highest levels of interoperability and portability of sample information between multiple repositories and other kinds of resources (e.g. e-infrastructures). In addition, identifying the required attributes for registering PIDs for biospecimen will pave the way for a framework of coupling the descriptive metadata to the digital object in a FAIR and comprehensive manner. The other initiative is development being undertaken with the Inventory (sample management) module of the RSpace electronic research notebook, in collaboration with the FAIMS3 field acquisition information management system. The aim is similar to SciLifeLab’s as described above: to facilitate portability and interoperability of sample information – in this case between a tool (RSpace) that supports user-friendly sample collection and management and association of sample data and metadata with experimental data – and other tools, repositories and e-infrastructures. Both initiatives aim to implement certain common core elements designed to FAIRify sample data: Association of variable domain-specific PIDS with sample data Incorporation of variable but standardized metadata schemas User-friendly collection of sample data in the field Scalable submission of sample metadata in standardized formats to domain repositories Automated and scalable passage of sample data and metadata within the respective systems and into external tools and resources Challenges faced in implementing each of these elements, and approaches to overcoming the challenges under consideration or implementation by the two initiatives, will be described. The potential role for the new IGSN sample identifier being developed by IGSN and DataCite will be highlighted.

description: Two of the main factors shaping an individual's opinion are social coordination and personal preferences, or personal biases. To understand the role of those and that of the topology of the network of interactions, we study an extension of the voter model proposed by Masuda and Redner (2011), where the agents are divided into two populations with opposite preferences. We consider a modular graph with two communities that reflect the bias assignment, modeling the phenomenon of epistemic bubbles. We analyze the models by approximate analytical methods and by simulations. Depending on the network and the biases' strengths, the system can either reach a consensus or a polarized state, in which the two populations stabilize to different average opinions. The modular structure has generally the effect of increasing both the degree of polarization and its range in the space of parameters. When the difference in the bias strengths between the populations is large, the success of the very committed group in imposing its preferred opinion onto the other one depends largely on the level of segregation of the latter population, while the dependency on the topological structure of the former is negligible. We compare the simple mean-field approach with the pair approximation and test the goodness of the mean-field predictions on a real network.

Mutually unbiased measurements for high-dimensional time-bin based photonic states

description: The task of measuring in two mutually unbiased bases is central to many quantum information protocols, as well as being of fundamental interest. Increasingly, there is an experimental focus on generating and controlling high-dimensional photonic states. One approach is to use the arrival time of a photon, which can be split into discrete time bins. An important problem associated with such states is the difficulty in experimentally realizing a measurement that is mutually unbiased with respect to the time-of-arrival. We propose a simple and compact scheme to measure in both the time of arrival basis and a basis that is approximately mutually unbiased with respect to the arrival time.

description: This project as an entirety is to provide a diagnosis of the ability for an individual attempting to shift their attention from one medium to the user. This will be demonstrated through testers playing a given video game which I have made, whilst the researcher will be asking questions related to how they are getting on, but not having an effect on the results, instead the results calculated will be the level of response as well as the time per question. To create accurate data for further research.
The intention of this diagnosis is to give trainee teachers a measurement to allow them to see if they are able to shift attention to students with autism. One approach is to get advice from professionals in the field, this includes teachers, learning support staff as well as experts who work with autism to get accurate results for the game.
Smart prediction for test smells refactorings
Creators: name: Martins, Luana
Publisher: name: Zenodo
Year: 2022

description: Test smells are considered bad practices for developing the test code. Their presence can reduce the test code quality, thus harming software testing and maintenance activities. Software refactoring has been a key practice to handle smells and improve software quality without changing its behavior. However, existing refactoring tools target production code with very different characteristics than test code. Despite the research invested in test smell refactoring, little is known about whether current refactorings improve the test code quality. This thesis proposal presents our research to help developers decide when and how to refactor test smells through a machine learning-based approach. First, we aim to mine refactorings performed by developers to derive a catalog of test-specific refactorings and their impact on the test code. Our findings show that developers prefer specific features of the testing frameworks, which may lead to test smells such as Inappropriate Assertion and Handling Exception. While the refactorings proposed in the literature aligned with the evolution of testing frameworks helps refactoring test smells, the Inappropriate Assertion remains unexplored in the literature. Second, we aim to collect and learn from test-specific refactorings to suggest which refactorings have the potential to fix test smells. As a result, the approach could support the test smells detection and refactoring guided to the practices closer to the developers’ perspective.
Origin of the diffuse 4-8 keV emission in M82

description: We present the first spatially resolved, X-ray spectroscopic study of the 4-8 keV diffuse emission found in the central part of the nearby starburst galaxy M82 on a few arcsecond scales. The new details that we see allow a number of important conclusions to be drawn on the nature of the hot gas and its origin as well as feedback on the ISM. We use archival data from Chandra with an exposure time of 570 ks. The Fexxv emission at 6.7 keV, expected from metal-enriched hot gas, is enhanced only in a limited area close to the starburst disc and is weak or almost absent over the rest of the diffuse emission, resulting in spatial variations in EW from <0.1 keV to 1.9 keV. This shows the presence of non-thermal emission due to inverse Compton scattering of the FIR photons by radio emitting cosmic ray electrons. The morphological resemblance between the diffuse X-ray, radio, and FIR emission maps supports this concept. Our decomposition of the diffuse emission spectrum indicates that ~70% of the 4-8 keV luminosity originates from the inverse Compton emission. The metal-rich hot gas with kT~5 keV makes a minor contribution to the 4-8 keV continuum, but it accounts for the majority of the observed Fexxv line. This hot gas appears to emerge from the circumnuclear starburst ring and fill the galactic chimneys identified as mid-infrared and radio emission voids. The energetics argument suggests that much of the supernova energy in the starburst site has gone into creating the chimneys and is transported to the halo. We argue that a hot, rarefied environment produced by strong supernova feedback results in displacing the brightest X-ray and radio supernova remnants which are instead found to reside in GMC. We find a faint X-ray source with a radio counterpart, close to the kinematic centre of the galaxy and we carefully examine the possibility that this source is a low-luminosity AGN in ADAF phase.

On Semicontinuity of Multiplicities in Families
Creators: name: Smirnov, Ilya
Publisher: name: Deutsche Mathematiker-Vereinigung
Year: 2020

description: This paper investigates the behavior of Hilbert-Samuel multiplicity and Hilbert-Kunz multiplicity in families of ideals. We show that Hilbert-Samuel multiplicity is upper semicontinuous and that Hilbert-Kunz multiplicity is upper semicontinuous in families of finite type. As a consequence, F-rational signature, an invariant defined by Hochster and Yao as the infimum of relative Hilbert-Kunz multiplicities, is, in fact, a minimum. This gives a different proof for its main property: F-rational signature is positive if and only if the ring is F-rational. The tools developed in this paper can be also applied to families over $\mathbb Z$ and yield a solution to Claudia Miller's question on reduction mod $p$ of Hilbert-Kunz function.

description: We present refined color-color selection criteria for identifying Wolf-Rayet (WR) stars using available mid infrared (MIR) photometry from WISE in combination with near infrared (NIR) photometry from 2MASS. Using a sample of spectrally classified objects, we find that WR stars are well distinguished from the field stellar population in the (W1-W2) vs. (J-Ks) color-color diagram, and further distinguished from other emission line objects such as Planetary Nebulae, Be, and Cataclysmic variable stars using a combination of NIR and MIR color constraints. As proof of concept we applied the color constraints to a photometric sample in the Galactic plane, located WR star candidates, and present five new spectrally confirmed and classified WC (1) and WN (4) stars. Analysis of the 0.8-5.0 micron spectral data for a subset of known, bright WC and WN stars shows that emission lines (primarily He I) extend into the 3.0 - 5.0 micron spectral region, although their strength is greatly diminished compared to the 0.8-2.5 micron region. The WR population stands out relative to background field stars at NIR and MIR colors due to an excess continuum contribution, likely caused by free-free scattering in dense winds. Mean photometric properties of known WRs are presented and imply that reddened late-type WN and WC sources are easier to detect than earlier-type sources at larger Galactic radii. WISE W3 and W4 images of 10 Wolf Rayet stars show evidence of circumstellar shells linked to mass ejections from strong stellar winds.

description: Water fountain stars represent a stage between the asymptotic giant branch (AGB) and planetary nebulae phases, when the mass loss changes from spherical to bipolar. These types of evolved objects are characterized by high-velocity jets in the 22 GHz water maser emission. We surveyed the CO and 13CO line emission towards a sample of ten water fountain stars through observing the J=1-0 and 2-1 lines of CO and 13CO, using the 30m IRAM radio telescope at Pico Veleta. All the water fountains visible from the observatory were surveyed. Most of the line emission arises from foreground or background Galactic clouds, and we had to thoroughly analyse the spectra to unveil the velocity components related to the stars. In two sources, IRAS 18460-0151 and IRAS 18596+0315, we identified wide velocity components with a width of 35-40 km/s that are centred at the stellar velocities. These wide components can be associated with the former AGB envelope of the progenitor star. A third case, IRAS 18286-0959, is reported as tentative; in this case a pair of narrow velocity components, symmetrically located with respect to the stellar velocity, has been discovered. We also modelled the line emission using an LVG code and derived some global physical parameters, which allowed us to discuss the possible origin of this gas in relation to the known bipolar outflows. For IRAS 18460-0151 and IRAS 18596+0315, we derived molecular masses close to 0.2 solar masses, mean densities of 10^4 cm^{-3}, and mass-loss rates of 10^{-4} M_sun/yr. The kinetic temperatures are rather low, between 10 and 50 K in both cases, which suggests that the CO emission is arising from the outer and cooler regions of the envelopes. No fitting was possible for IRAS 18286-0959, because line contamination can not be discarded in this case.

Pollenia flavipalpis

description: [Pollenia flavipalpis] Rondani, 1862d: 202.
REMARKS: misspelling. Rondani (1862d: 202) used the name Pollenia flavipalpis for Pollenia fulvipalpis Macquart, 1835 in his key (p. 196) and index (p. 236). Bezzi & Stein (1907: 525, 527) and Schumann (1986: 49) considered Pollenia flavipalpis as a nomen dubium in Polleniinae. Rognes (1991b: 366) considered the name “ flavipalpis ” as an incorrect subsequent spelling of fulvipalpis Macquart, 1835.

description: We propose a method for coupling a tapered optical fiber to an inverted tapered SiN waveguide by fabricating a microfiber using 3D nanoprinting lithography. The microfiber consists of three parts: a tapered cladding cap, an S-bend, and a straight part, all composed of high-refractive-index material. Light is adiabatically coupled from the tapered fiber to the printed microfiber through the cladding cap. The light is then transmitted through the S-bend and the straight part with low loss and is finally coupled to the waveguide through the evanescent field. In the simulation, our design can achieve a high coupling efficiency (TE mode) of ~97% at a wavelength of 1542 nm with a wide bandwidth of ~768 nm at the 1-dB cut-off criterion.

description: Rhiniidae
This family of calyptrate flies contains 382 predominantly tropical species (Evenhuis & Pape 2020). It is unknown in the Nearctic and Neotropical regions (Marshall 2012). Rondani (1861e, 1865 c, 1873e, 1875c) described two Palaearctic, two Oriental, and one Afrotropical species in his “ Stirps Stomoxidinae ”. The family Rhiniidae was proposed by Brauer & Bergenstamm (1889). One nominal species is currently considered as valid, four as junior synonyms (James 1977, Pont 1980 b, Schumann 1986, Pape et al. 1995). The type material is distributed between the MZUF (Palaearctic) and the MSNG (Oriental and Afrotropical).

description: We study subproduct systems in the sense of Shalit and Solel arising from stochastic matrices on countable state spaces, and their associated operator algebras. We focus on the non-self-adjoint tensor algebra, and Viselter's generalization of the Cuntz-Pimsner C*-algebra to the context of subproduct systems. Suppose that $X$ and $Y$ are Arveson-Stinespring subproduct systems associated to two stochastic matrices over a countable set $Ω$, and let $\mathcal{T}_+(X)$ and $\mathcal{T}_+(Y)$ be their tensor algebras. We show that every algebraic isomorphism from $\mathcal{T}_+(X)$ onto $\mathcal{T}_+(Y)$ is automatically bounded. Furthermore, $\mathcal{T}_+(X)$ and $\mathcal{T}_+(Y)$ are isometrically isomorphic if and only if $X$ and $Y$ are unitarily isomorphic up to a *-automorphism of $\ell^\infty(Ω)$. When $Ω$ is finite, we prove that $\mathcal{T}_+(X)$ and $\mathcal{T}_+(Y)$ are algebraically isomorphic if and only if there exists a similarity between $X$ and $Y$ up to a *-automorphism of $\ell^\infty(Ω)$. Moreover, we provide an explicit description of the Cuntz-Pimsner algebra $\mathcal{O}(X)$ in the case where $Ω$ is finite and the stochastic matrix is essential.

description: The `blazar sequence' has been proposed for more than 20 years, yet its nature is still unclear. In this work, for the first time, we expand this topic to the TeV band by using a sample of 58 TeV blazars including 48 blazars in the quiescent state and 21 blazars in the flaring state. We investigate the correlation between the TeV luminosity, which has been compensated for attenuation from extragalactic background light, and the synchrotron peak frequency. We note that there is no correlation between TeV luminosity and peak frequency in the quiescent state and a strong anti-correlation in the flaring state for the observed value. However, there is a strong positive correlation in both the quiescent state and the flaring state for the intrinsic value. This indicates that the blazar sequence is shown in the flaring state rather than in the quiescent state for the observed value and the blazar sequence is not present in both two states after removing the beaming effect. In addition, to confirm whether the beaming effect results in the blazar sequence, we compare the \textit{Fermi} $γ$-ray luminosity between the quiescent state and the flaring state. We find the \textit{Fermi} $γ$-ray luminosity in the flaring state is greater than that in the quiescent state and the Doppler factor in the flaring state is greater. We suggest the blazar sequence in the flaring state may be due to the stronger beaming effect.

description: In this paper, using the Finslerian settings, we study the existence of parallel one forms (or, equivalently parallel vector fields) on a Riemannian manifold. We show that a parallel one form on a Riemannian manifold M is a holonomy invariant function on the tangent bundle T M with respect to the geodesic spray. We prove that if the metrizability freedom of the geodesic spray of (M, F) is 1, then the (M, F) does not admit a parallel one form. We investigate a sufficient condition on a Riemannian manifold to admit a parallel one form. As a by-product, we relate the existence of a proper affine Killing vector field by the metrizability freedom. We establish sufficient conditions for the existence of a parallel one form on a Finsler manifold. By counter-examples, we show that if the metrizability freedom is greater than 1, then the manifold (Riemannian or Finslerian) does not necessarily admit a parallel one form. Various special cases and examples are studied and discussed.

description: In untargeted metabolomics a majority of the acquired MS/MS spectra typically remains unidentified. In part, this is due to the fact that the molecular coverage of reference spectral libraries is necessarily incomplete. However, even if an exact match cannot be found in a spectral library, it is often possible to propagate annotations to structurally related molecules. We have created a "suspect" reference spectral library, consisting of putative molecule identities and a loss or addition characterized by a difference in precursor mass. By propagating library annotations to previously unidentified spectra using repository-scale molecular networking, we are able to extract 79,461 high-quality suspect spectra in a data-driven fashion from 92,063 raw files originating from 1,289 heterogeneous public datasets deposited to GNPS. This forms a rich data resource of novel, real-life, reference spectra that will be freely available for the community to use via GNPS.

description: It is generally believed that superconductivity only weakly affects the indirect exchange between magnetic impurities. If the distance r between impurities is smaller than than the superconducting coherence length (r < ξ), this exchange is thought to be dominated by RKKY interactions, identical to the those in a normal metallic host. This perception is based upon a perturbative treatment of the exchange interaction. Here, we provide a non-perturbative analysis and demonstrate that the presence of Yu-Shiba-Rusinov bound states induces a strong 1/r^2 anti-ferromagnetic interaction that can dominate over conventional RKKY even at distances significantly smaller than the coherence length. Experimental signatures, implications and applications are discussed.

Pont det. 1975 / Saltella parmensis Ex. Coll. Big. / S. parmensis ♂ Italia, Rond.
CURRENT STATUS: junior synonym of Saltella sphondylii (Schrank, 1803) (Zuska & Pont 1984: 158, Pont & Meier 2002: 28, 114).
REMARKS: Rondani (1874d: 13) described both sexes of Saltella parmensis without specifying either the number or the length of the specimens, but presumably from more than one specimen because he stated: “ non raro legitur [found not rarely]”. Pont & Meier (2002: 114) reported an unspecified number of syntypes in the MZUF and one male syntype in the OUMNH without publishing any lectotype designation. We found six syntypes in the MZUF and one in the OUMNH during our study.

description: We study the essential dimension of representations of a fixed quiver with given dimension vector. We also consider the question of when the genericity property holds, i.e., when essential dimension and generic essential dimension agree. We classify the quivers satisfying the genericity property for every dimension vector and show that for every wild quiver the genericity property holds for infinitely many of its Schur roots. We also construct a large class of examples, where the genericity property fails. Our results are particularly detailed in the case of Kronecker quivers.

description: We consider flavor constraints on, and collider signatures of, Asymmetric Dark Matter (ADM) via higher dimension operators. In the supersymmetric models we consider, R-parity violating (RPV) operators carrying B-L interact with n dark matter (DM) particles X through an interaction of the form W = X^n O_{B-L}, where O_{B-L} = q l d^c, u^c d^c d^c, l l e^c. This interaction ensures that the lightest ordinary supersymmetric particle (LOSP) is unstable to decay into the X sector, leading to a higher multiplicity of final state particles and reduced missing energy at a collider. Flavor-violating processes place constraints on the scale of the higher dimension operator, impacting whether the LOSP decays promptly. While the strongest limitations on RPV from n-\bar{n} oscillations and proton decay do not apply to ADM, we analyze the constraints from meson mixing, mu-e conversion, mu -> 3 e and b -> s l^+ l^-. We show that these flavor constraints, even in the absence of flavor symmetries, allow parameter space for prompt decay to the X sector, with additional jets and leptons in exotic flavor combinations. We study the constraints from existing 8 TeV LHC SUSY searches with (i) 2-6 jets plus missing energy, and (ii) 1-2 leptons, 3-6 jets plus missing energy, comparing the constraints on ADM-extended supersymmetry with the usual supersymmetric simplified models.

description: This paper questions how to approach threat modelling in the automotive domain at both an abstract level that features no domain-specific entities such as the CAN bus and, separately, at a detailed level. It addresses such questions by contributing a systematic method that is currently affected by the analyst's subjectivity because most of its inner operations are only defined informally. However, this potential limitation is overcome when candidate threats are identified and left to everyone's scrutiny. The systematic method is demonstrated on the established LINDDUN threat modelling methodology with respect to 4 pivotal works on privacy threat modelling in automotive. As a result, 8 threats that the authors deem not representable in LINDDUN are identified and suggested as possible candidate extensions to LINDDUN. Also, 56 threats are identified providing a detailed, automotive-specific model of threats.

Involutions of Azumaya Algebras
Creators: name: First, Uriya A.
name: Williams, Ben
Publisher: name: Deutsche Mathematiker-Vereinigung
Year: 2020

description: We consider the general circumstance of an Azumaya algebra $A$ of degree $n$ over a locally ringed topos $(\mathbf{X}, \mathcal O_\mathbf{X})$ where the latter carries a (possibly trivial) involution, denoted $\lambda$. This generalizes the usual notion of involutions of Azumaya algebras over schemes with involution, which in turn generalizes the notion of involutions of central simple algebras. We provide a criterion to determine whether two Azumaya algebras with involutions extending $\lambda$ are locally isomorphic, describe the equivalence classes obtained by this relation, and settle the question of when an Azumaya algebra $A$ is Brauer equivalent to an algebra carrying an involution extending $\lambda$, by giving a cohomological condition. We remark that these results are novel even in the case of schemes, since we allow ramified, non-trivial involutions of the base object. We observe that, if the cohomological condition is satisfied, then $A$ is Brauer equivalent to an Azumaya algebra of degree $2n$ carrying an involution. By comparison with the case of topological spaces, we show that the integer $2n$ is minimal, even in the case of a nonsingular affine variety $X$ with a fixed-point free involution. As an incidental step, we show that if $R$ is a commutative ring with involution for which the fixed ring $S$ is local, then either $R$ is local or $R/S$ is a quadratic \'etale extension of rings.

description: We consider a free-fermion chain with a conformal defect that features an extended zero mode, and study the entanglement properties in its mixed ground state. The zero-mode induced degeneracy modifies the density of states in the single-particle entanglement spectrum, which can be calculated via the full counting statistics. For a homogeneous chain, the resulting change in the Rényi entropy is derived analytically for arbitrary subsystem ratios in the thermodynamic limit. For a conformal defect located in the center, analogous results can be obtained for the half-chain entanglement. In particular, we observe parity effects for half-chains with even/odd sites, which do not decay with size.

description: Eumerus uncipes Rondani, 1850
ORIGINAL DESCRIPTION: 1850a: 119 (key, as “ ancipes ”), 123 (description, as “ uncipes ”).
TYPE LOCALITY: “ in agro parmense tam in planitie quam in collibus [Parmese plains and hills (Italy)]”.
TYPE MATERIAL: 2 ♂♂, syntypes (one with left hind-leg glued to a cardboard stage pinned below specimen) (MZUF: Box 4): Eumerus Mgn / uncipes Rdn., ♂ / 132; 5 ♀♀, syntypes (one missing head; one with abdomen partially eaten by dermestids; one covered with mold) (MZUF: Box 4): Eumerus Mgn / uncipes Rdn., ♀ / 132; 1 ♂, syntype (MRSN): Parma / Eumerus uncipes Rond. / Museo di Zoologia della Università di Torino; 1 ♂, syntype (MZUB: Box 320): 20 25 / Eumerus uncipes Rond., ex a. parmensi / uncipes Rndn., ♂, Parma.
CURRENT STATUS: valid species (Peck 1988: 164, Belcari et al. 1995a: 16).
REMARKS: Rondani (1850a: 123) described both sexes of Eumerus uncipes without specifying the exact number of specimens and not giving a range of lengths, but presumably from more than one specimen because he wrote: “ non infrequens [not rare]”. We found nine syntypes in this study. Rondani spelled the species as “ ancipes ” (p. 119) in his key, but as “ uncipes ” in his description (p. 123). Acting as First Reviser (according to I.C.Z.N. 1999: Article 24.2.4), Rondani (1857: 85, 91) determined the correct spelling as “ uncipes ”.

description: This paper presents a new discrete event-based network simulator named TARVOS - Computer Networks Simulator, being designed as part of the first Author's Masters research and will provide support to simulating MPLS architecture, several RSVP-TE protocol functionalities and fast recovery in case of link failure. The tool is used in a case study, where the impact of a link failure on a VoIP application, within an MPLS domain network, is analyzed. The paper displays a preliminary research of six already available simulators and reasons why they were not adopted as tools for the Masters research. Then, it follows to describe the basics of TARVOS implementation and exhibits the case study simulated by this new tool.

Gaussian field theory for the Brownian motion of a solvated particle

description: An alternative derivation of Brownian motion is presented. Instead of supplementing the linearized Navier-Stokes equation with a fluctuating force, we directly assume a Gaussian action functional for solvent velocity fluctuations. Solvating a particle amounts to expelling the solvent and prescribing a boundary condition to the solvent on the interface that is shared with the solute. We study the dynamical effects of this boundary condition on the solvent and derive explicit expressions for the solvent mean flow and velocity correlations. Moreover, we show that the probability to observe solvent velocity fluctuations that are compatible with the boundary condition reproduces random Brownian motion of the solvated particle. We explicitly calculate the translational and rotational diffusion coefficients of a spherical particle using the presented formalism.

description: We analyse a set of collisionless disc galaxy simulations to study the consequences of bar formation and evolution on the M-sigma relation of supermassive black holes. The redistribution of angular momentum driven by bars leads to a mass increase within the central region, raising the velocity dispersion of the bulge, sigma, on average by ~12% and as much as ~20%. If a disc galaxy with a SMBH satisfying the M-sigma relation forms a bar, and the SMBH does not grow in the process, then the increase in sigma moves the galaxy off the M-sigma relation. We explore various effects that can affect this result including contamination from the disc and anisotropy. The displacement from the M-sigma relation for individual model barred galaxies correlates with both M(B)/M(B+D) and beta_phi(B+D) measured within the effective radius of the bulge. Overall, this process leads to an M-sigma for barred galaxies offset from that of unbarred galaxies, as well as an increase in its scatter. We assemble samples of unbarred and barred galaxies with classical bulges and find tentative hints of an offset between the two consistent with the predicted. Including all barred galaxies, rather than just those with a classical bulge, leads to a significantly larger offset.

description: We investigate the mass-metallicity relationship of star forming galaxies by analysing the absorption line spectra of $\sim$200,000 galaxies in the Sloan Digital Sky Survey. The galaxy spectra are stacked in bins of stellar mass and a population synthesis technique is applied yielding metallicities, ages and star formation history of the young and old stellar population together with interstellar reddening and extinction. We adopt different lengths of the initial starbursts and different initial mass functions for the calculation of model spectra of the single stellar populations contributing to the total integrated spectrum. We also allow for deviations of the ratio of extinction to reddening RV from 3.1 and determine the value from the spectral fit. We find that burst length and RV have a significant influence on the determination of metallicities whereas the effect of the initial mass function is small. RV values are larger than 3.1. The metallicities of the young stellar population agree with extragalactic spectroscopic studies of individual massive supergiant stars and are significantly higher than those of the older stellar population. This confirms galaxy evolution models where metallicity depends on the ratio of gas to stellar mass and where this ratio decreases with time. Star formation history is found to depend on galaxy stellar mass. Massive galaxies are dominated by stars formed at early times.

description: We analyse different properties of the small scale environment of Seyfert 2 for two samples selected according to the accretion rate parameter, R, from the DR7-SDSS survey. We compare the results with two control samples of non-active galaxies that cover the same redshift range, luminosity, colours, morphology, age and stellar mass content. Our study shows that both high and low accretion rate subsamples reside in bluer and lower density environments than the control samples. However, we find that this difference is at least two times stronger for the low accretion rate Seyferts. In the vicinity of Seyfert 2, red galaxies have systematically lower values of stellar-mass as compared with corresponding control samples. The lower values of stellar mass for red neighbours is more significant at higher density environments and it is more evident for low accretion rate Seyfert. We also find that this effect is independent of the host's stellar mass. Our results are consistent with a scenario where AGN occurrence is higher in lower/medium density environments with a higher merger rate and a lack of a dense intergalactic medium (that can strip gas from these systems) that provide suitable conditions for the central black hole feeding. We find this particularly evident for the low accretion rate Seyferts that could compensate through the intergalactic medium the lack of gas of their hosts.

description: We construct geometric models for classifying spaces of linear algebraic groups in $G$-equivariant motivic homotopy theory, where $G$ is a tame group scheme. As a consequence, we show that the equivariant motivic spectrum representing the homotopy $K$-theory of $G$-schemes (which we construct as an $E_\infty$-ring) is stable under arbitrary base change, and we deduce that the homotopy $K$-theory of $G$-schemes satisfies cdh descent.
