description: In this work we revisit the proposed multi-circumbinary system RZ Dra. We find the proposed system to be highly unstable. We attempt to find a best-fit light-travel time model rendering the orbits to follow stable orbits. We found a best-fit solution, but the resulting orbits also exhibit short-term orbital instabilities. We therefore conclude that the observed timing variation must be due to other astrophysical effects causing a change in the binary orbital period. Follow-up observations of this system is encouraged.

description: The aim of this paper is to examine critically Peter Szondi’s literary hermeneutics from the perspective of his “huphainologic” concept, which stems from the Aristotle-inspired poetological character of this hermeneutics. In order to perform this task, I seek to answer the question whether Szondi’s text- and scriptocentrism is not a consequence of its neglect of the Jewish exegetical tradition. For the sake of giving an adequate analysis of problems raised by this question, I contrast the occidental, text-centered concept of Revelation with its oriental counterpart based on consonant script. As a next step, in this context, I give an outline of the reading- and interpretation-centred concept of Scripture characteristic of the period of Tannaim, touching upon the topic of middot (the methods or principles used by rabbinical hermeneutics), as well as exploring the dynamic nature and exegetical creativity of the reading- and interpretation-centred approach to Hebrew Revelation.

Publisher: name: Zenodo
Year: 2019

description: In this study, a two-stage process was conducted. The first stage was carrying out for the activation process of Peanut shell powder at different temperatures and concentrations to select the optimum parameters. The second stage was bleaching of Niger seed oil using the chosen activated peanut shell powder adsorbent. The peanut shell collected from Sululta, Ethiopia was activated by phosphoric acid, and further bleaching experiments were conducted to assess the activated powders effect on the bleaching capacity of Niger seed oil. The Two key parameters of the acid activation process were acid concentration and activation temperature. The highest bleaching capacity was obtained around 3M acid concentration and at 350oC of activation temperature as optimal activation. The PSP and PAAPSP at optimal condition were characterized by XRD, FTIR and SEM with EDS. The results of the XRD showed that the PSP is composed of cellulose, hemicellulose and lignin polysaccharide. The XRD analysis of PAAPSP illustrated the presence of crystalline carbonaceous structure and different alumino silicate minerals. X-ray and FTIR data confirmed that acid activation degrades cellulose. The results of the analysis by Energy Dispersive Spectroscopy (EDS) showed that, presence of carbon, oxygen, silica, alumina and phosphorous.
Seeding Black Holes in Cosmological Simulations

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We present a new model for the formation of black holes in cosmological simulations, motivated by the first star formation. Black holes form from high density peaks of primordial gas, and grow via both gas accretion and mergers. Massive black holes heat the surrounding material, suppressing star formation at the centres of galaxies, and driving galactic winds. We perform an investigation into the physical effects of the model parameters, and obtain a `best' set of these parameters by comparing the outcome of simulations to observations. With this best set, we successfully reproduce the cosmic star formation rate history, black hole mass -- velocity dispersion relation, and the size -- velocity dispersion relation of galaxies. The black hole seed mass is 10^3Msun, which is orders of magnitude smaller than has been used in previous cosmological simulations with active galactic nuclei, but suggests that the origin of the seed black holes is the death of Population III stars.

description: Background: The current article aims to explore the protective potentials of α-tocopherol
alone and the combination of allicin and vitamin B-complex against lead-acetate
neurotoxicity on the cerebellar cortex.
Materials and methods: Forty rats were divided into four groups (n=10). Group 1 was the
control group. Group 2 received 10 mg/kg body weight (BW) of lead acetate. Group 3 was
exposed to 10 mg/kg BW of lead acetate plus a combination of allicin (100 mg/kg BW)
and vit. B-complex (40 mg/kg BW). Group 4 was administered lead acetate (10 mg/kg
BW) and α-tocopherol (100 mg/kg BW). The animals received treatment for sixty days by
oral gavage. All the groups were studied ultrastructurally and immunohistochemically with
glial fibrillary acidic protein (GFAP).
Results: The affected groups revealed shrunken and degenerated Purkinje cells with
irregular nuclei. The cytoplasm comprised several lysosomes, unhealthy mitochondria, and
dilated Golgi saccules. The myelinated nerve fibers demonstrated breaking of the myelin
sheaths, apparent vacuoles, and broad axonal spaces. Immunohistochemically, there was a
tremendous surge in GFAP-positive astrocytes in the lead acetate-treated group. These
histological and ultrastructural variations were ameliorated by the administration of α-
tocopherol and the combination of allicin and vit. B complex. Moreover, an apparent
decrease in the number of GFAP-positive astrocytes was obvious in the protected groups.
Conclusions: Although both α-tocopherol and the combination of allicin and vit. Bcomplex can be used as possible adjuvant therapies to ameliorate nervous system ailments
attributable to lead acetate, α-tocopherol showed more protective potential.

description: In this paper I try to answer the question if – and if so, how – the dialogue between Literary Studies and Linguistics can (still) be enriching for both disciplines. The aim is to reflect briefly on those events that brought about a distancing between Linguistics and Literature in German Studies in Italy, with regard to theory, methodology and empiricism. In addition, it will explore the causes of their recent – albeit timid though nevertheless present – encounter. The theme is discussed using German Studies as an example within the general scholarly area of “Foreign Linguistics and Literature”.

description: We describe the public release of the Cluster Monte Carlo (CMC) code, a parallel, star-by-star N-body code for modeling dense star clusters. CMC treats collisional stellar dynamics using Hénon’s method, where the cumulative effect of many two-body encounters is statistically reproduced as a single effective encounter between nearest-neighbor particles on a relaxation timescale. The star-by-star approach allows for the inclusion of additional physics, including strong gravitational three- and four-body encounters, two-body tidal and gravitational-wave captures, mass loss in arbitrary galactic tidal fields, and stellar evolution for both single and binary stars. The public release of CMC is pinned directly to the COSMIC population synthesis code, allowing dynamical star cluster simulations and population synthesis studies to be performed using identical assumptions about the stellar physics and initial conditions. As a demonstration, we present two examples of star cluster modeling: first, we perform the largest (N = 10$^{8}$) star-by-star N-body simulation of a Plummer sphere evolving to core collapse, reproducing the expected self-similar density profile over more than 15 orders of magnitude; second, we generate realistic models for typical globular clusters, and we show that their dynamical evolution can produce significant numbers of black hole mergers with masses greater than those produced from isolated binary evolution (such as GW190521, a recently reported merger with component masses in the pulsational pair-instability mass gap).

description: This contribution offers insights and reflections on the teaching of digital discourse in academic English language curricular courses. These considerations originate from pluriannual research activity on the digital remediation of specialized languages and out of the teaching of these contents in the modules of a European project dedicated to the design and implementation of a transnational study program that merges multimodal digital literacy and English for international communication. The paper also argues for the integration of basic concepts of information technology in linguistic studies of digitally remediated English language in order to teach students how to communicate in the era of the so-called “computational turn”.

description: In standard nucleation theory, the nucleation process is characterized by computing $ΔΩ(V)$, the reversible work required to form a cluster of volume $V$ of the stable phase inside the metastable mother phase. However, other quantities besides the volume could play a role in the free energy of cluster formation, and this will in turn affect the nucleation barrier and the shape of the nucleus. Here we exploit our recently introduced mesoscopic theory of nucleation to compute the free energy cost of a nearly-spherical cluster of volume $V$ and a fluctuating surface area $A$, whereby the maximum of $ΔΩ(V)$ is replaced by a saddle point in $ΔΩ(V,A)$. Compared to the simpler theory based on volume only, the barrier height of $ΔΩ(V,A)$ at the transition state is systematically larger by a few $k_BT$. More importantly, we show that, depending on the physical situation, the most probable shape of the nucleus may be highly non spherical, even when the surface tension and stiffness of the model are isotropic. Interestingly, these shape fluctuations do not influence or modify the standard Classical Nucleation Theory manner of extracting the interface tension from the logarithm of the nucleation rate near coexistence.

description: The spectra of the coronal hole radio emission in solar cycles 23 and 24 have been studied based on RATAN-600 data in the 4-16.5 GHz range at frequencies of 5.7 and 17 GHz and 327 MHz. It has been found that bright features of coronal hole microwave emission at 17 GHz and dark features at 5.7 GHz can exist in coronal holes when the spectral index is 1.25-1.5 in the 6.5-16.5 GHz range; the radio spectrum in this range is flat when coronal holes are indiscernible against the background of a quiet Sun. The possible vertical scale of the solar atmosphere over coronal holes is discussed.

description: Thioacetamide (TAA) has been used in development of animal models of acute hepatic encephalopathy (AHE). This experimental study was designed to evaluate effects of oral administration of vitamin C, vitamin E and their combination on liver and brain enzymes and their histologic and ultrastructure changes. Eighty Wistar rats were included and divided into five groups (16 each). Group 1 (control) received saline once intraperitoneally (IP) then administered orally saline and corn oil for 3 days. Group 2 [hepatotoxic (TAA)] were received TAA (300 mg/kg) once intraperitoneally (IP). Group 3 (vitamin C and TAA) received TAA (300 mg/kg) once intraperitoneally (IP) and then administered orally vitamin C (100 mg/kg) daily for 3 days. Group 4 (vitamin E and TAA) received TAA (300 mg/kg) once intraperitoneally (IP) and then administered orally vitamin E (200 mg/kg) daily for 3 days. Group 5 (vitamin C and vitamin E and TAA) received TAA (300 mg/kg) once intraperitoneally (IP) and then administered orally vitamin C (100 mg/kg) in combination with vitamin E (200 mg/kg) daily for 3 days. All rats were sacrificed 24 h after last treatment under anesthesia. Blood samples were collected and serum was obtained for analysis of aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), total protein, triglyceride, cholesterol using spectrophotometer and ELISA kits. Liver and brain were extracted and tissue homogenate was used to measure malondialdehyde (MDA), reduced glutathione (GSH) and nitric oxide (NO). Histological and ultrastructure examination were done. TAA induced significant increase of MDA and decreased in GSH and NO in both liver and brain homogenate with more liver affection, and increased in serum levels of AST, ALT, triglyceride, cholesterol and decreased in total protein. Furthermore, there is decrease in serum levels of AST, ALT, triglyceride, cholesterol and tissue levels of MDA and elevated serum total protein and tissue GSH and NO under the umbrella of vitamin C and vitamin E and their combination, although vitamin E is more efficient. These data showed protective effect of vitamins C and E, especially vitamin E against oxidative stress and hepatic and brain damage, and histological architecture of the liver in rats’ model of acute hepatic encephalopathy elicited by TAA.
Faddeev calculations of the $\bar{K}NN$ system with chirally-motivated $\bar{K}N$ interaction. I. Low-energy $K^- d$ scattering and antikaonic deuterium

description: A chirally-motivated coupled-channel $\bar{K}N$ potential, reproducing all low-energy experimental data on $K^- p$ scattering and kaonic hydrogen and suitable for using in accurate few-body calculations, was constructed. The potential was used for calculations of low-energy amplitudes of the elastic $K^- d$ scattering using Faddeev-type AGS equations with coupled $\bar{K}NN$ and $πΣN$ channels. A complex $K^- - d$ potential reproducing the three-body $K^- d$ amplitudes was constructed and used for calculation of $1s$ level shift and width of kaonic deuterium. The predicted shift $ΔE_{1s}^{K^- d} \sim -830$ eV and width $Γ_{1s}^{K^- d} \sim 1055$ eV are close to our previous results obtained with phenomenological $\bar{K}N$ potentials.

description: The recent book of poems by Davide Puccini (Il fondo e L’onda, Nomos Edizioni 2016) is a fervent and intimate inventory of the world of childhood and adolescence recollected through playing, environments and objects sunk in the oblivion of the bottom of the sea or brought afloat by the waves. The past can, however, be remembered thanks to poetic words. Apart from much literary interference the poems are linked to the Author’s previous works and have a surprising recovery in the coming-of-age novel that Puccini published in 2018.

Diversity in the outcome of dust radial drift in protoplanetary discs

description: The growth of dust particles into planet embryos needs to circumvent the radial-drift barrier, i.e. the accretion of dust particles onto the central star by radial migration. The outcome of the dust radial migration is governed by simple criteria between the dust-to-gas ratio and the exponents p and q of the surface density and temperature power laws. The transfer of radiation provides an additional constraint between these quantities because the disc thermal structure is fixed by the dust spatial distribution. To assess which discs are primarily affected by the radial-drift barrier, we used the radiative transfer code MCFOST to compute the temperature structure of a wide range of disc models, stressing the particular effects of grain size distributions and vertical settling. We find that the outcome of the dust migration process is very sensitive to the physical conditions within the disc. For high dust-to-gas ratios (> 0.01) or flattened disc structures (H/R < 0.05), growing dust grains can efficiently decouple from the gas, leading to a high concentration of grains at a critical radius of a few AU. Decoupling of grains can occur at a large fraction (> 0.1) of the initial radius, for a dust-to-gas ratio greater than ~ 0.05. The exact value of the required dust-to-gas ratio for dust to stop its migration is strongly dependent on the disc temperature structure. Non growing dust grains are accreted for discs with flat surface density profiles (p<0.7) while they always remain in the disc if the surface density is steep enough (p>1.2). Both the presence of large grains and vertical settling tend to favour the accretion of non growing dust grains onto the central object, but it slows down the migration of growing dust grains. All the disc configurations are found to have favourable temperature profiles over most of the disc to retain their planetesimals.

description: These three recent publications focus on the study of German-speaking literature between the end of World War II in 1945 and today. In the first volume, Calzoni focuses on literary production immediately after 1945 until the building of the Berlin Wall; in the second volume his target is literary production between 1961 and today, with particular attention to its relation with mass media. Hermann and Horstkotte concentrate their reflections and analysis on the period after the Berlin Wall (1989) and the present days. The year 1989-1990 represents a significant hiatus in literary production and is considered the starting point for the development of a new form of literature that has to face multifaceted, globalised contemporary society.

description: This review of “Ancor che tristo ha suoi diletti il vero”, an interpretation of Zibaldone 2999 (SEF, 2018) by Martina Romanelli focuses on an observation made on 21 July 1823 concerning late 16th century theatre. This analysis comprises the early stages in a theoretical revolution which will radically change the poetry of Leopardi. Starting from this unusual interpretation, which over the years was to influence other observations regarding Zibaldone, Romanelli returns to a crucial phase in Leopardi’s reflections on the sense and justification of chorus as a medium for poetry. The choral dimension, in all its variants, offers an extensive panorama not only for Leopardi’s opera omnia, but also for dramatic art in general, from the great Dionysian to the modern.

description: The aim of this study was to evaluate the satisfaction and menstrual bleeding pattern with levonorgestrel-releasing intrauterine systems (LNG-IUD) in young women. A prospective, multicentre, non-interventional study with 1-year follow-up was conducted in Spain. Participants were women between 18 and 30 years old who freely choose any available LNG-IUD for contraception. Satisfaction with LNG-IUD was measured with a 5-point Likert scale. Type of LNG-IUD, menstrual bleeding pattern and satisfaction with it, easiness of insertion and pain during procedure were collected. A total of 555 women (37.3% parous, 62.7% nulliparous) (mean age 25.8 ± 3.5) completed the study. After 12 months, 92.4% of women were satisfied or very satisfied with the LNG-IUD, with no differences by parity status, type of IUD or baseline menstrual bleeding pattern. Satisfaction with the LNG-IUD correlated with satisfaction with menstrual bleeding pattern at 12 months. Up to 88.7% of women were satisfied or very satisfied with their menstrual bleeding pattern at 12 months in comparison to 41.5% at baseline (p < 0.001). Adverse events (AE)-related discontinuation rate was low (2.2%). Satisfaction with LNG-IUD is very high among young Spanish women, regardless of parity and menstrual bleeding pattern at baseline.

description: With its seven chapters, the latest book by Gilberto Lonardi proposes a personal miscellany and some unpublished works. The fil rouge is an element that has interested the author for a long time, as the centre of a series of publications that occupied over ten years. According to Lonardi’s studies, the poetry of Homer and, with it, the whole aesthetic dimension of the ancient world, represent an inalienable presupposition of Leopardi’s literary identity, continuing to interact with a poetry that constantly has to re-consider itself.

Massive Jackiw-Rebbi Model

description: In this paper we analyze a generalized Jackiw-Rebbi (J-R) model in which a massive fermion is coupled to the kink of the $λϕ^4$ model as a prescribed background field. We solve this massive J-R model exactly and analytically and obtain the whole spectrum of the fermion, including the bound and continuum states. The mass term of the fermion makes the potential of the decoupled second order Schrodinger-like equations asymmetric in a way that their asymptotic values at two spatial infinities are different. Therefore, we encounter the unusual problem in which two kinds of continuum states are possible for the fermion: reflecting and scattering states. We then show the energies of all the states as a function of the parameters of the kink, i.e. its value at spatial infinity ($θ_0$) and its slope at $x=0$ ($μ$). The graph of the energies as a function of $θ_0$, where the bound state energies and the two kinds of continuum states are depicted, shows peculiar features including an energy gap in the form of a triangle where no bound states exist. That is the zero mode exists only for $θ_0$ larger than a critical value $(θ_0^{\textrm{c}})$. This is in sharp contrast to the usual (massless) J-R model where the zero mode and hence the fermion number $\pm1/2$ for the ground state is ever present. This also makes the origin of the zero mode very clear: It is formed from the union of the two threshold bound states at $θ_0^{\textrm{c}}$, which is zero in the massless J-R model.

description: The interplay between magnetic vortex polarity, chirality and the curvature of the underlying surface results in a dependence of the vortex polarity switching efficiency on the vortex chirality. The switching is studied numerically by applying a short Gauss pulse of the external magnetic field to a spherical cap within its cut plane. The minimum field intensity required for the switching essentially depends on the vortex chirality and it does not depend on the initial vortex polarity. This effect decreases with the curvature radius increasing and it vanishes in the planar limit.

description: To evaluate the actual perceptions about combined hormonal contraceptives (CHCs) use in BRCA mutation carriers in comparison to women from the general population. This was a cross-sectional, observational study involving two Italian referral centres for hereditary cancers. An identical questionnaire investigating how CHC use could affect the risk of developing some types of cancer, specific diseases, and symptoms was administered to 85 BRCA mutation carriers and 85 healthy women without this genetic mutation (control group). Women’s perceptions were evaluated using specific questions and Likert scales (−5 to +5). Perceptions about the effects of CHC use on developing specific diseases and symptoms did not differ between BRCA mutation carriers and controls. Conversely, the protective effects of CHC use on colorectal (p = .02), uterine body (p = .01) and ovarian (p = .01) cancers were unknown by BRCA mutation carriers. Moreover, BRCA mutation carriers recognised the association between CHC use and a higher risk of breast (p = .0008) and uterine cervix cancer (p = .007). Investing time and effort in transmitting the correct key messages about oncological risk related to CHC use could potentially increase their use in BRCA mutation carriers.

description: The Research Data Alliance Data Policy Standardisation and Implementation Interest Group is concerned with data policy standardisation in particular journal data policies and funder data policies, which are known to promote and incentivise data sharing by researchers. We call for collaboration across the scholarly publishing and wider research community to drive further implementation and adoption of consistent research data policies. Our meeting objectives for Plenary 16 were two-fold: Journal data policies - continue engaging with publishers and journals, in particular with industry associations such as STM, to promote implementation and adoption of standard research data policies - and planning these initiatives in ways that enables measurement and analysis of the impact of policies. Funder data policies - discuss a potential project to examine funder-publisher policy alignment in collaboration with the Research Funders and Stakeholders Open Research and Data Management Policies IG. Research funders and research publishers are key actors in driving the transition towards a research culture where data and other research outputs are FAIR. However comparatively little work has been done to examine funder-publisher policy alignment. This presents a significant knowledge gap that hinders progress towards more consistent good practice in research data management and, ultimately, the shift towards a FAIR research system. In addition to the presentation slides, the Menti audience poll results are also included here.

description: The effects of edge hydrogenation and hydroxylation on the relative stability and electronic properties of hexagonal boron nitride quantum dots (h-BNQDs) are investigated. Zigzag edge hydroxylation is found to result in considerable energetic stabilization of h-BNQDs as well as a reduction of their electronic gap with respect to their hydrogenated counterparts. The application of an external in-plane electric field leads to a monotonous decrease of the gap. When compared to their edge-hydrogenated counterparts, significantly lower field intensities are required to achieve full gap closure of the zigzag edge hydroxylated h-BNQDs. These results indicate that edge chemistry may provide a viable route for the design of stable and robust electronic devices based on nanoscale hexagonal boron-nitride systems.

Security concerns of ipv6-slaac and security policies to diminish the risk associated with them

description: Though, IPv6 has presented a long list of features that will actually change the entire networking environment, it still represents a very small proportion of Internet traffic. One of the major reasons behind its partial acceptance is its security, as these features were incorporated in IPv6 just to enhance its overall performance and quality of service, thereby neglecting its security part. One such feature is Stateless Address Auto Configuration or simply SLAAC, which have undoubtedly reduced a lot of overhead in configuring networks, but on the same time it has challenged the security of IPv6 networks. This research work, therefore targets at proposing some security policies to mitigate the risks associated with SLAAC, by understanding its working scenario and trying to create the possible attack vector to highlight its security concerns. Hence, the implementation of these policies will directly add security to networks and make them resistant to SLAAC based attacks.

description: We give a short and elementary proof of a $(q, μ, ν)$-deformed Binomial distribution identity arising in the study of the $(q, μ, ν)$-Boson process and the $(q, μ, ν)$-TASEP. This identity found by Corwin in [4] was a key technical step to prove an intertwining relation between the Markov transition matrices of these two classes of discrete-time Markov chains. This was used in turn to derive exact formulas for a large class of observables of both these processes.

description: The UV properties of old stellar populations have been subject of intense scrutiny from the late sixties, when the UV-upturn in early type galaxies was first discovered. Because of their proximity and relative simplicity, Galactic globular clusters (GGCs) are ideal local templates to understand how the integrated UV light is driven by hot stellar populations, primarily horizontal branch stars and their progeny. Our understanding of such stars is still plagued by theoretical uncertainties, which are partly due to the absence of an accurate, comprehensive, statistically representative homogeneous data-set. To move a step forward on this subject, we have combined the HST and GALEX capabilities and collected the largest data-base ever obtained for GGCs in UV. This data-base is best suited to provide insights on the HB second parameter problem and on the first stages of GCs formation and chemical evolution and to understand how they are linked to the observed properties of extragalactic systems.

description: Luca Baratta’s book consists of a catalogue of forty-eight full-length documents – street literature, such as broadside ballads, pamphlets and leaflets, as well as medical writings drawn from Philosophical Transactions – that all deal with the phenomenon of monstrous births in early modern England. The volume is divided in four parts: “God’s judgment (1550-1603)”, “The Great Amazement (1603-1642)”, “The Monsters’ Wars (1642-1660)”, and “The Age of Wonders, the Age of Science (1660-1715)”. In each section, the documents are distributed according to a chronological order, with the aim to show the metamorphoses that the perceptions and representations of monsters have gone through in the course of time: from prodigies with religious implications to objects of curiosity and scientific enquiry.

The similarity of attractive and repulsive forces on a lattice

description: On a lattice, as the momentum space is compact, the kinetic energy is bounded not only from below but also from above. It is shown that this, somehow removes the distinction between repulsive and attractive forces. In particular, it is seen that a region with attractive force would appear forbidden for states with energies higher than a certain value, while repulsive forces could develop bound-states. An explicit transformation is introduced which transforms the spectrum of a system corresponding to a repulsive force, to that of a similar system corresponding to an attractive force. Explicit numerical examples are presented for discrete energies of bound-states of a particle experiencing repulsive force by a piecewise constant potential. Finally, the parameters of a specific one dimensional translationally invariant system on continuum are tuned so that the energy of the system resembles the kinetic energy of a system on a one dimensional lattice. In particular, it is shown that the parameters could be tuned so that while the width of the first energy band and its position are kept finite, the energy gap between the first energy band and the next energy band go to infinity, so that effectively only the first energy band is relevant.
