Spirulina supplementation

description: Our experimental work was aimed at evaluating the safety and protective effects of dietary spirulina supplementation on the kidney of newborn rats, the offspring of lead contaminated lactating mothers. Female rats were randomly divided into four groups: group I (control) was given a normal diet, group II (positive control, S) received a diet enriched with spirulina, group III received only lead through drinking water (Pb), and group IV received both a diet enriched with spirulina and lead contaminated water (S Pb). The treatment of pregnant rats with lead administrated in drinking water, from the 5th day of pregnancy until day 14 after delivery, induced an increased level of renal lipid peroxidation, protein carbonyl, hydrogen peroxide and advanced oxidation protein product, a decreased renal content of glutathione and antioxidant enzyme activities such as superoxide dismutase, catalase and glutathione peroxidase in newborns. A statistically significant increase of renal DNA, mRNA, hematological parameters as well as in plasma urea and creatinine serum levels and lactate dehydrogenase was seen in pups, while those of uric acid declined. Interestingly, these biochemical modifications were accompanied by a significant decrease of lactate dehydrogenase in kidney, plasma alkaline phosphatase and gamma glutamyl-transpeptidase levels, urinary levels of creatinine and urea. Conversely, supplementation of lead-treated mother's with spirulina alleviated hematotoxicity induced by lead as evidenced, by restoring the biochemical markers cited above to near normal levels. Nevertheless, the distorted histoarchitecture in rat kidney attenuated following spirulina supplementation. It can be then concluded that spirulina is an important protective source against kidney impairments.

description: One of the fundamental open questions in cosmology is whether we can regard the universe evolution without singularity like a Big Bang or a Big Rip. This challenging subject stimulates one to regard a nonsingular universe in the far past with an arbitrarily large vacuum energy. Considering the high energy regime in the cosmic history, it is believed that Einstein gravity should be corrected to an effective energy dependent theory which could be acquired by gravity's rainbow. On the other hand, employing massive gravity provided us with solutions to some of the long standing fundamental problems of cosmology such as cosmological constant problem and self acceleration of the universe. Considering these aspects of gravity's rainbow and massive gravity, in this paper, we initiate studying FRW cosmology in the massive gravity's rainbow formalism. At first, we show that although massive gravity modifies the FRW cosmology, but it does not itself remove the big bang singularity. Then, we generalize the massive gravity to the case of energy dependent spacetime and find that massive gravity's rainbow can remove the early universe singularity. We bring together all the essential conditions for having a nonsingular universe and the effects of both gravity's rainbow and massive gravity generalizations on such criteria are determined.

description: The formation of planetesimals requires that primordial dust grains grow from micron- to kilometer-sized bodies. Dust traps caused by gas pressure maxima have been proposed as regions where grains can concentrate and grow fast enough to form planetesimals, before radially migrating onto the star. We report new VLA Ka and Ku observations of the protoplanetary disk around the Herbig Ae/Be star MWC 758. The Ka image shows a compact emission region in the outer disk, indicating a strong concentration of big dust grains. Tracing smaller grains, archival ALMA data in band 7 continuum shows extended disk emission with an intensity maximum to the northwest of the central star, which matches the VLA clump position. The compactness of the Ka emission is expected in the context of dust trapping, as big grains are trapped more easily than smaller grains in gas pressure maxima. We develop a nonaxisymmetric parametric model inspired by a steady-state vortex solution with parameters adequately selected to reproduce the observations, including the spectral energy distribution. Finally, we compare the radio continuum with SPHERE scattered light data. The ALMA continuum spatially coincides with a spiral-like feature seen in scattered light, while the VLA clump is offset from the scattered light maximum. Moreover, the ALMA map shows a decrement that matches a region devoid of scattered polarized emission. Continuum observations at a different wavelength are necessary to conclude whether the VLA-ALMA difference is an opacity or a real dust segregation

La struttura finanziaria dei gruppi quotati italiani attraverso l'analisi dei bilanci consolidati
Creators: name: Cecchi, Massimo
Publisher: name: Economia Aziendale Online
Year: 2017
Subjects: Gruppi, bilancio consolidato, leva azionaria, leva finanziaria

description: La rappresentazione della struttura finanziaria dei gruppi italiani fornita in letteratura è duplice.
Da un lato, secondo il modello tipico del capitalismo renano, in Italia sembrano prevalere strutture proprietarie concentrate rispetto a quelle con azionariato diffuso che, invece, contraddistinguono il capitalismo anglosassone. La scarsa propensione dei risparmiatori ad investire in capitale di rischio implicherebbe, infatti, che le risorse finanziarie, anziché transitare dal mercato, vengano convogliate verso intermediari quali le banche che a loro volta finanziano le imprese con capitale di debito.
Dall’altro si rileva che nel nostro paese prevalgono strutture di gruppo piramidali dove il capitale di controllo si concentrerebbe al vertice della piramide e poi, tramite il meccanismo della leva azionaria, si creerebbero ampie minoranze che sono tali pur apportando ingenti risorse, poiché divise e frazionate in molteplici società. Inoltre, sempre secondo tale visione, la maggioranza adotterebbe anche comportamenti predatori ai danni delle minoranze, tendendo a espropriarne le risorse attraverso meccanismi quali il “tunneling”.
La presente ricerca, s’inserisce entro tale dibattito, utilizzando una chiave di lettura prettamente economico-aziendale; verificando cioè direttamente la struttura finanziaria dei gruppi quotati attraverso l’analisi dei loro bilanci consolidati.
Rispetto a ricerche precedenti costituisce quindi una focalizzazione sull’area di consolidamento dei gruppi quotati, che, utilizzando dati ufficiali e comparabili, ha il vantaggio di offrire un quadro tendenzialmente obiettivo, dal quale emergono alcune conferme, ma anche nuove evidenze e spunti di riflessione.

Towards the comprehension of Corporate Governance choices: new perspectives and possible solutions

description: Corporate governance development can be observed and analyzed from

innumerable points of view.
These perspectives concern specific conditions promoted by the involved political systems and by the economic scenario in which companies operate. Italian evidence of SMEs clearly shows the approach to the corporate psychology can be an interesting perspective in order to identify the causes conditioning the entrepreneurial choices if we consider that the new nature of enterprises has been clearly affected from the entrepreneurs’ conception of doing business. The choice of the entrepreneurial initiative, the subsequent managerial decisions, and more generally the entrepreneurial fabric development are completely
involved in such a principle. This paper aims to comprehend the new entrepreneurial overview in the context of new corporate governance choices by using the innovative perspective of corporate psychology.

Secure Continuous Variable Teleportation and Einstein-Podolsky-Rosen Steering

description: We investigate the resources needed for secure teleportation of coherent states. We extend continuous variable teleportation to include quantum teleamplification protocols that allow nonunity classical gains and a preamplification or postattenuation of the coherent state. We show that, for arbitrary Gaussian protocols and a significant class of Gaussian resources, two-way steering is required to achieve a teleportation fidelity beyond the no-cloning threshold. This provides an operational connection between Gaussian steerability and secure teleportation. We present practical recipes suggesting that heralded noiseless preamplification may enable high-fidelity heralded teleportation, using minimally entangled yet steerable resources.

Start-ups and SMEs investment features: spotlight on Italian reality

Subjects: start-up; SME; investor; investment stages; Italy; Europe

description: Access to finance has been acknowledged on research, practitioners and policy sides as being one of the most important factors for start-up activity and SME development and growth. Notwithstanding this importance, a holistic view of the Italian market in terms of types of investors, investment stages and dominant investment patterns is missing as is a comparison with the larger European context.

We aim to shed more light on this topic in order to identify and explain potential differences in investment practices for start ups and SMEs. Such findings will be of great value for all players involved. Entrepreneurs may be able to better address their investment requests, investors may find a benchmark with Europe useful in order to develop or redress their current activities and, finally, policy makers will be able to identify and design programs which are able to fill the gap between private investors and investment needs of start-ups and SMEs which are the backbone of economic activity in Italy.

Our analysis shows that, as compared to the European practice, investment in Italy remains mainly confined to the early stages while funding of growth and expansion is negligible but we also identify differences in investment levels and sectorial distribution.

Notes. Megachile scultupuralis, a distinctive exotic species of East Asian origin, has recently spread across the Northeast and Midwest regions of the country (Hinojosa-Díaz 2008; Magnum & Brooks 1997). It was first recorded from Michigan in 2008 from Wayne and Cheboygan Counties in the southeast and north of the LP, respectively (O’Brien & Craves 2008). The species, known to have been present in the state from at least 2006 (see below; the first Illinois specimen was also collected that year, see Tonietto & Ascher 2009), is active in midsummer. It is known to nest in active Xylocopa virginica burrows in dead wood (Laport & Minckley 2012; Roulston & Malfi 2012) and has been observed in Michigan removing nesting materials of other Megachile species from trap nests (JG pers. obs.).

Thermodynamic description and quasinormal modes of adS black holes in Born-Infeld massive gravity with a non-abelian hair

description: We construct a new class of asymptotically (a)dS black hole solutions of Einstein-Yang-Mills massive gravity in the presence of Born-Infeld nonlinear electrodynamics. The obtained solutions possess a Coulomb electric charge, massive term and a non-abelian hair as well. We calculate the conserved and thermodynamic quantities, and investigate the validity of the first law of thermodynamics. Also, we investigate thermal stability conditions by using the sign of heat capacity through canonical ensemble. Next, we consider the cosmological constant as a thermodynamical pressure and study the van der Waals like phase transition of black holes in the extended phase space thermodynamics. Our results indicate the existence of a phase transition which is affected by the parameters of theory. Finally, we consider a massless scalar perturbation in the background of asymptotically adS solutions and calculate the quasinormal modes by employing the pseudospectral method. The imaginary part of quasinormal frequencies is the time scale of a thermal state (in the conformal field theory) for the approach to thermal equilibrium.

description: We discuss a Curie-Weiss model with two groups with different coupling constants within and between groups. For the total magnetisations in each group, we show bivariate laws of large numbers and a central limit theorem which is valid in the high temperature regime. In the critical regime, the total magnetisation normalised by $N^{3/4}$ converges to a non-trivial distribution which is not Gaussian, just as in the single-group Curie-Weiss model. Finally, we prove a kind of a `law of large numbers' in the low temperature regime, more precisely we prove that the empirical magnetisation converges in distribution to a mixture of two Dirac measures.
description: The third version contains some new results as well as the critical regime results from arXiv:1807.05020

description: In this paper, we first investigate the thermal stability of black holes in conformal Weyl gravity with a comparison with the Schwarzschild black holes. Then, we consider a minimally coupled massive scalar perturbation and calculate the quasinormal modes in asymptotically dS spacetime by employing the sixth order WKB approximation and asymptotic iteration method. The deviations from those of the Schwarzschild-dS solutions are obtained and the possibility of the presence of quasi-resonance modes for Weyl black hole solutions is investigated. Finally, we consider a massless scalar perturbation in the background of asymptotically AdS solutions and calculate the quasinormal modes by using the pseudospectral method. The effects of the free parameter of the theory on the quasinormal modes are studied and deviations from those of the Schwarzschild-AdS black holes are investigated. The imaginary part of quasinormal frequencies in AdS spacetime is the time scale of a thermal state (in the conformal field theory) to approach thermal equilibrium.

description: The degree of influence that the environment and mass have on the stellar populations of early-type galaxies is uncertain. In this paper, we present the results of a spectroscopic analysis of the stellar populations of early-type galaxies aimed at addressing this question. The sample of galaxies is drawn from four clusters, with (z) = 0.04, and their surrounding structure extending to ∼10Rvir. We find that the distributions of the absorption-line strengths and the stellar population parameters, age, metallicity and α-element abundance ratio, do not differ significantly between the clusters and their outskirts, but the tight correlations found between these quantities and the velocity dispersion within the clusters are weaker in their outskirts. All three stellar population parameters of cluster galaxies are positively correlated with the velocity dispersion. Galaxies in clusters form a homogeneous class of objects that have similar distributions of line-strengths and stellar population parameters, and follow similar scaling relations, regardless of the cluster richness or morphology. We estimate the intrinsic scatter of the Gaussian distribution of metallicities to be 0.3 dex, while that of the α-element abundance ratio is 0.07 dex. The e-folding time of the exponential distribution of galaxy ages is estimated to be 900 Myr. The intrinsic scatters of the metallicity and α-element abundance ratio distributions can almost entirely be accounted for by the correlations with the velocity dispersion and the intrinsic scatter about these relations. This implies that the galaxy mass plays a major role in determining its stellar population.

description: Inspired by the work of Cherry, we introduce and study a new notion of Brody hyperbolicity for rigid analytic varieties over a non-archimedean field $K$ of characteristic zero. We use this notion of hyperbolicity to show the following algebraic statement: if a projective variety admits a non-constant morphism from an abelian variety, then so does any specialization of it. As an application of this result, we show that the moduli space of abelian varieties is $K$-analytically Brody hyperbolic in equal characteristic zero. These two results are predicted by the Green-Griffiths-Lang conjecture on hyperbolic varieties and its natural analogues for non-archimedean hyperbolicity. Finally, we use Scholze's uniformization theorem to prove that the aforementioned moduli space satisfies a non-archimedean analogue of the "Theorem of the Fixed Part" in mixed characteristic.

description: A confidence sequence is a sequence of confidence intervals that is uniformly valid over an unbounded time horizon. Our work develops confidence sequences whose widths go to zero, with nonasymptotic coverage guarantees under nonparametric conditions. We draw connections between the Cramér-Chernoff method for exponential concentration, the law of the iterated logarithm (LIL), and the sequential probability ratio test -- our confidence sequences are time-uniform extensions of the first; provide tight, nonasymptotic characterizations of the second; and generalize the third to nonparametric settings, including sub-Gaussian and Bernstein conditions, self-normalized processes, and matrix martingales. We illustrate the generality of our proof techniques by deriving an empirical-Bernstein bound growing at a LIL rate, as well as a novel upper LIL for the maximum eigenvalue of a sum of random matrices. Finally, we apply our methods to covariance matrix estimation and to estimation of sample average treatment effect under the Neyman-Rubin potential outcomes model.

Its close similarity to the abundant M. rotundata, differing from the latter by the narrower shape of the vertex and gena dorsally and fainter T2 fovea, may partially explain why it is not commonly recognized. The identity of North American populations were only recently clarified (Soltani et al. 2017). Previously, these bees were identified as M. concinna Smith, but this species sensu stricto is now unknown from the continental United States, although there are North American records from the Greater and Lesser Antilles. Cavity nesting was described from Arizona and Tennessee as M. concinna (Butler & Ritchie 1965; Butler & Wargo 1963; Krombein 1967).

description: We study the Kasparov product on (possibly non-compact and incomplete) Riemannian manifolds. Specifically, we show on a submersion of Riemannian manifolds that the tensor sum of a regular vertically elliptic operator on the total space and an elliptic operator on the base space represents the Kasparov product of the corresponding classes in KK-theory. This construction works in general for symmetric operators (i.e. without assuming self-adjointness), and extends known results for submersions with compact fibres. The assumption of regularity for the vertically elliptic operator is not always satisfied, but depends on the topology and geometry of the submersion, and we give explicit examples of non-regular operators. We apply our main result to obtain a factorisation in unbounded KK-theory of the fundamental class of a Riemannian submersion, as a Kasparov product of the shriek map of the submersion and the fundamental class of the base manifold.

description: We give a long exact sequence for the homology of a graded atomic lattice equipped with a sheaf of modules, in terms of the deleted and restricted lattices. This is then used to compute the homology of the arrangement lattice of a hyperplane arrangement equipped with the natural sheaf. This generalises an old result of Lusztig.

description: There is increasing evidence that many galaxies host both a nuclear star cluster (NC) and a super-massive black hole (SMBH). Their coexistence is particularly prevalent in spheroids with stellar mass 108–1010 M⊙. We study the possibility that a stellar-mass black hole (BH) hosted by a NC inspirals and merges with the central SMBH. Due to the high stellar density in NCs, extreme mass-ratio inspirals (EMRIs) of BHs onto SMBHs in NCs may be important sources of gravitational waves (GWs). We consider sensitivity curves for three different space-based GW laser interferometric mission concepts: the Laser Interferometer Space Antenna (LISA), the New Gravitational wave Observatory (NGO) and the DECi-hertz Interferometer Gravitational wave Observatory (DECIGO). We predict that, under the most optimistic assumptions, LISA and DECIGO will detect up to thousands of EMRIs in NCs per year, while NGO will observe up to tens of EMRIs per year. We explore how a number of factors may affect the predicted rates. In particular, if we assume that the mass of the SMBH scales with the square of the host spheroid mass in galaxies with NCs, rather than a linear scaling, then the event rates are more than a factor of 10 lower for both LISA and NGO, while they are almost unaffected in the case of DECIGO.
Asymptotic escape rates and limiting distributions for multimodal maps

Subjects: subject: Dynamical Systems (math.DS)
subject: FOS: Mathematics

description: We consider multimodal maps with holes and study the evolution of the open systems with respect to equilibrium states for both geometric and Hölder potentials. For small holes, we show that a large class of initial distributions share the same escape rate and converge to a unique absolutely continuous conditionally invariant measure; we also prove a variational principle connecting the escape rate to the pressure on the survivor set, with no conditions on the placement of the hole. Finally, introducing a weak condition on the centre of the hole, we prove scaling limits for the escape rate for holes centred at both periodic and nonperiodic points, as the diameter of the hole goes to zero.

description: We will exhibit a group of symmetries of the simply-laced quantum connections, generalising the quantum/Howe duality relating KZ and the Casimir connection. These symmetries arise as a quantisation of the classical symmetries of the simply-laced isomonodromy systems, which in turn generalise the Harnad duality. The quantisation of the classical symmetries involves constructing the quantum Hamiltonian reduction of the representation variety of any simply-laced quiver, both in filtered and in deformation quantisation.

Pro-definability of spaces of definable types

description: We show pro-definability of spaces of definable types in various classical complete first order theories, including complete o-minimal theories, Presburger arithmetic, $p$-adically closed fields, real closed and algebraically closed valued fields and closed ordered differential fields. Furthermore, we prove pro-definability of other distinguished subspaces, some of which have an interesting geometric interpretation. Our general strategy consists in showing that definable types are uniformly definable, a property which implies pro-definability using an argument due to E. Hrushovski and F. Loeser. Uniform definability of definable types is finally achieved by studying classes of stably embedded pairs.
description: We divide the original article into two parts. The current update contains the work about uniform definability and pro-definability in different theories. The part concerning strict pro-definability and axiomatization of tame pairs will be updated separately

description: The Low-Frequency Array radio telescope discovered the $707$ Hz binary millisecond pulsar (MSP) J0952$-$0607 in a targeted radio pulsation search of an unidentified $\textit{Fermi}$ gamma-ray source. This source shows a weak energy flux of $F_γ= 2.6 \times 10^{-12}\,\text{erg}\,\text{cm}^{-2}\,\text{s}^{-1}$ in the energy range between $100\,\text{MeV}$ and $100\,\text{GeV}$. Here we report the detection of pulsed gamma-ray emission from PSR$\,$J0952$-$0607 in a very sensitive gamma-ray pulsation search. The pulsar's rotational, binary, and astrometric properties are measured over seven years of $\textit{Fermi}$-Large Area Telescope data. For this we take into account the uncertainty on the shape of the gamma-ray pulse profile. We present an updated radio-timing solution now spanning more than two years and show results from optical modeling of the black-widow-type companion based on new multi-band photometric data taken with HiPERCAM on the Gran Telescopio Canarias on La Palma and ULTRACAM on the New Technology Telescope at ESO La Silla. PSR$\,$J0952$-$0607 is now the fastest-spinning pulsar for which the intrinsic spin-down rate has been reliably constrained ($\dot{P}_\text{int} \lesssim 4.6 \times 10^{-21}\,\text{s}\,\text{s}^{-1}$). The inferred surface magnetic field strength of $B_\text{surf} \lesssim 8.2 \times 10^{7}\,\text{G}$ is among the ten lowest of all known pulsars. This discovery is another example of an extremely fast spinning black-widow pulsar hiding within an unidentified $\textit{Fermi} gamma-ray source. In the future such systems might help to pin down the maximum spin frequency and the minimum surface magnetic field strength of MSPs.

Thinking outside the halo: tracing the large-scale distribution of diffuse cosmic metals with semi-analytic models

Publisher: name: Swinburne
Year: 2024

description: With the installation of the Cosmic Origins Spectrograph on the Hubble Space Telescope, measurements of the metal content of the low redshift intergalactic medium (IGM) are now available. Using a new grid-based model for diffuse gas coupled to the SAGE semi-analytic model of galaxy formation, we examine the impact of supernova feedback on the pollution of the IGM. We consider different assumptions for the reheating and ejection of gas by supernovae and their dependence on galaxy circular velocity and gas surface density. Where metals are present, we find the most likely metallicity to be −1.5
Hölder continuity of $ω$-minimizers of functionals with generalized Orlicz growth

description: We show local Hölder continuity of quasiminimizers of functionals with non-standard (Musielak--Orlicz) growth. Compared with previous results, we cover more general minimizing functionals and need fewer assumptions. We prove Harnack's inequality and a Morrey type estimate for quasiminimizers. Combining this with Ekeland's variational principle, we obtain local Hölder continuity for $ω$-minimizers.
