description: Coma is frequently used as the archetype z~0 galaxy cluster to compare higher redshift work against. It is not clear, however, how representative the Coma cluster is for galaxy clusters of its mass or X-ray luminosity, and significantly: recent works have suggested that the galaxy population of Coma may be in some ways anomolous. In this work, we present a comparison of Coma to an X-ray selected control sample of clusters. We show that although Coma is typical against the control sample in terms of its internal kinematics (substructure and velocity dispersion profile), it has a significantly high (~3sigma) X-ray temperature set against clusters of comparable mass. By de-redshifting our control sample cluster galaxies star-formation rates using a fit to the galaxy main sequence evolution at z < 0.1, we determine that the typical star-formation rate of Coma galaxies as a function of mass is higher than for galaxies in our control sample at a confidence level of > 99 per cent. One way to alleviate this discrepency and bring Coma in-line with the control sample would be to have the distance to Coma to be slightly lower, perhaps through a non-negligible peculiar velocity with respect to the Hubble expansion, but we do not regard this as likely given precision measurements using a variety of approaches. Therefore in summary, we urge caution in using Coma as a z~0 baseline cluster in galaxy evolution studies.

description: Congenital short QT syndrome is a very low prevalence inherited primary arrhythmia syndrome first reported in 2000 by Gussak et al., who described two families with a short QT interval, syncope, and sudden cardiac death. In 2004, Ramon Brugada et al. identified the first genetic type of this entity. To date, a total of nine genotypes have been described. The diagnosis is easy from the electrocardiogram (ECG), not only due to the short QT duration, but also based on other aspects covered in this review. During 24-h Holter monitoring, paroxysmal atrial fibrillation spontaneously converting to sinus rhythm may be found. Even though the T wave may appear symmetric on the ECG, the T loop of the vectorcardiogram confirms that the T wave is constantly asymmetric due to the presence of dashes closer to each other in the efferent branch. In this review, we also describe the minus-plus T wave sign that we have described in a previously published article. In addition to congenital causes, we briefly highlight the existence of numerous acquired causes of short QT interval.

description: In relativistic heavy-ion physics two-particle correlations provide a very useful tool to investigate the Quark-Gluon Plasma (QGP). This observable is sensitive to several of the properties of the QGP such as resonances, interaction of partons with the medium and collective effects (e. g. elliptic flow). In the present work, the correlation function between electrons from heavy-flavour hadron decays and light hadrons was measured in pp and Pb-Pb collisions (central and semi-central). Furthermore, in pp collisions the relative beauty contribution to the total cross section of electrons from heavy-flavour decays was estimated by comparing the measured correlation with Monte-Carlo templates.

description: Two methods for applying a lower bound to the variation induced by the Monte Carlo effect are trialled. One of these is implemented in the widely used probabilistic genotyping system, STRmix™. Neither approach is giving the desired 99% coverage. In some cases the coverage is much lower than the desired 99%. The discrepancy (i.e. the distance between the LR corresponding to the desired coverage and the LR observed coverage at 99%) is not large. For example, the discrepancy of 0.23 for approach 1 suggests the lower bounds should be moved downwards by a factor of 1.7 to achieve the desired 99% coverage.

description: This work presents an efficient solution procedure for the elastohydrodynamic (EHD) contact problem considering structural dynamics. The contact bodies are modeled using reduced finite element models. Singly diagonal implicit Runge-Kutta (SDIRK) methods are used for adaptive time integration. The structural model is coupled with the nonlinear Reynolds Equation using a monolithic coupling approach. Finally, a reduced order model of the complete nonlinear coupled problem is constructed.
Thermal Casimir Effect for Rectangular Cavities inside D+1-dimensional Minkowski Spacetime Revisited

description: We reconsider the thermal scalar Casimir effect for $p$-dimensional rectangular cavity inside $D+1$-dimensional Minkowski space-time. We derive rigorously the regularization of the temperature-dependent part of the free energy by making use of the Abel-Plana formula repeatedly and get the explicit expression of the terms to be subtracted. In the cases of $D$=3, $p$=1 and $D$=3, $p$=3, we precisely recover the results of parallel plates and three-dimensional box in the literature. Furthermore, for $D>p$ and $D=p$ cases with periodic, Dirichlet and Neumann boundary conditions, we give the explicit expressions of the Casimir free energy in both low temperature (small separations) and high temperature (large separations) regimes, through which the asymptotic behavior of the free energy changing with temperature and the side length is easy to see. We find that for $D>p$, with the side length going to infinity, the Casimir free energy tends to positive or negative constants or zero, depending on the boundary conditions. But for $D=p$, the leading term of the Casimir free energy for all three boundary conditions is a logarithmic function of the side length. We also discuss the thermal Casimir force changing with temperature and the side length in different cases and find with the side length going to infinity the force always tends to zero for different boundary conditions regardless of $D>p$ or $D=p$. The Casimir free energy and force at high temperature limit behave asymptotically alike in that they are proportional to the temperature, be they positive (repulsive) or negative (attractive) in different cases. Our study may be helpful in providing a comprehensive and complete understanding of this old problem.

description: The study presents the development of cleaner beamhouse processes to facilitate the extraction of collagen from fleshing waste. 0.8% offer level of alkali protease in soaking process is observed to be optimum for opening up the fibre texture of the hide, and to provide good yield of fleshing waste. In addition to this, complete removal of hair is still an issue of concern for unhairing using enzymes. CLRI had developed a novel protease for unhairing and the effectiveness of this protease for unhairing in the presence of lipase as co-enzymes was study and presented in this thesis. Experimental results indicated that 1% lipase followed by 4% protease treatment improved the unhairing efficacy. The enzymatically dehaired hide was further analyse by SEM, and the complete removal of hair in the experimental process (1% lipase followed by 4% protease) is further established. The reduction in pollution load parameters viz., BOD, COD, TOC, TDS and TSS is 89.375%, 88.57%, 85.79%, 47.37% and 48.57%, respectively with reference to conventional unhairing process. The leathers processed from optimized soaking and unhairing system showed comparable strength characteristics with reference to leather processed with chemical unhairing system.

description: In recent years, telecollaboration has proved to be a useful tool in the acquisition of foreign languages and intercultural communicative skills (Belz 2003b; Clavel-Arroitia, Pennock-Speck 2015a, 2015b; Hewitt, Brett 2007; O’Dowd 2007; Su et al., 2005). This paper focuses on how prepared secondary-school teachers believe they are in order to successfully implement telecollaboration in the classroom. To gather information on their views we carried out an online survey of 179 secondary school foreign language teachers and a series of focus group interviews in the context of a European project, TeCoLa. The advantage of the double- pronged approach to data collection, quantitative and qualitative, is that it provides us with a more complete picture of teachers’ needs.

description: The issue of using informative priors for estimation of mixtures at multiple time points is examined. Several different informative priors and an independent prior are compared using samples of actual and simulated aerosol particle size distribution (PSD) data. Measurements of aerosol PSDs refer to the concentration of aerosol particles in terms of their size, which is typically multimodal in nature and collected at frequent time intervals. The use of informative priors is found to better identify component parameters at each time point and more clearly establish patterns in the parameters over time. Some caveats to this finding are discussed.

Transformation through telecollaboration: A working hypothesis on the transformative potential of blended spaces for (Italian) foreign language acquisition in South Africa
Creators: name: Virga, Anita
Publisher: name: Firenze University Press
Year: 2018
Subjects: blended learning; curriculum transformation; Italian language; Skype project; South Africa

description: This article formulates a working hypothesis on the transformative potential of telecollaborative projects in a foreign language classroom in South Africa. It is based on a project which has been already successfully implemented in Australia. The working idea is to transfer this project into the South African context, where the use of technology may be helpful both to improve the quality of students’ learning experience and to address the transformative demand coming from the South African society. The essay both illustrates the transformational potential of digital spaces of blended foreign language acquisition and suggests how current blending strategies deployed abroad may be re-thought and re-shaped so as to better match the peculiarities of the South African context.

Middle High German

description: In the context of the first German-language written documents of the 13th century, which were collected in one edition by the linguistically motivated and very carefully compiled Corpus der altdeutschen Originalurkunden bis zum Jahr 1300, the first German-language preambles (“Arengen”) appear. On the one hand, these preambles’ motifs can be traced back to those of older preambles, but on the other hand, they also have syntactical peculiarities. When categorising the preambles, one notices that there is usually a straightforward connection between the respective documents, e.g. a common issuer. This is however not the case for a motif that appears in seven charters.

Here it is worth taking a closer look at the documents in order to explore the preamble‘s origin. To facilitate a structured and detailed comparison, a multifaceted criteria grid is applied: To what extent do the document formulas resemble each other? Were they written by the same scribe and sealed in the same way? Are there personal similarities, i.e. issuers, recipients, witnesses? Finally, the social and political context of the documents need to be taken into consideration as the preambles can be assigned to the political sphere of influence of the Upper Swabian bailiwick and were issued almost exclusively to women‘s monasteries. How could that be related to the motif and generally to the use of a preamble? All in all, the study aims at a multidimensional and interdisciplinary analysis of documents, which is grounded in auxiliary sciences of history and enables the individual study to be placed in a larger context.

As will be shown, the seven charters are more dependent on the recipient than the issuer, even if ultimately no reliable pattern for the preamble‘s distribution can be established. It can be assumed, for example, that the German language of formulas was more commonly used in women‘s convents. The fact that four documents originate from the same scribe and were sealed in the same way indicates a mobile “public” person (“öffentlicher Schreiber”) who could have been responsible for them. This instance is neither a chancery nor a notary‘s office, but it does provide an illuminating insight into notarial practice in Upper Swabia at the end of the 13th century.

description: We study a two-band model of fermions in a 1d chain with an antisymmetric hybridization that breaks inversion symmetry. We find that for certain values of its parameters, the $sp$-chain maps formally into a $p$-wave superconducting chain, the archetypical 1d system exhibiting Majorana fermions. The eigenspectra, including the existence of zero energy modes in the topological phase, agree for both models. The end states too share several similarities in both models, such as the behavior of the localization length, the non-trivial topological index and robustness to disorder. However, we show by mapping the $s$- and $p$- fermions to two copies of Majoranas, that the excitations in the ends of a finite $sp$ chain are indeed conventional fermions though endowed with protected topological properties. Our results are obtained by a scattering approach in a semi-infinite chain with an edge defect treated within the $T$-matrix approximation. We augment the analytical results with exact numerical diagonalization that allow us to extend our results to arbitrary parameters and also to disordered systems.

description: The ejecta discharged by impacting meteorites can redistribute a planetary ring's mass and angular momentum. This `ballistic transport' of ring properties instigates a linear instability that could generate the 100--1000-km undulations observed in Saturn's inner B-ring and in its C-ring. We present semi-analytic results demonstrating how the instability sustains steadily travelling nonlinear wavetrains. At low optical depths, the instability produces approximately sinusoidal waves of low amplitude, which we identify with those observed between radii 77,000 and 86,000 km in the C-ring. On the other hand, optical depths of 1 or more exhibit hysteresis, whereby the ring falls into multiple stable states: the homogeneous background equilibrium or large-amplitude wave states. Possibly the `flat zones' and `wave zones' between radii 93,000 and 98,000 km in the B-ring correspond to the stable homogeneous and wave states, respectively. In addition, we test the linear stability of the wavetrains and show that only a small subset are stable. In particular, stable solutions all possess wavelengths greater than the lengthscale of fastest linear growth. We supplement our calculations with a weakly nonlinear analysis that suggests the C-ring reproduces some of the dynamics of the complex Ginzburg--Landau equation. In the third paper in the series, these results will be tested and extended with numerical simulations.

Transcriptomic Analysis Reveals Differential Transcriptional Regulation Underlying Citrus Bacterial Canker (CBC) Tolerance in Citrus sinensis

description: The sustainable development of the citrus industry is greatly affected by citrus canker, an important bacterial disease. To explore the transcriptional regulatory mechanism of citrus resistance to canker disease, this study used the susceptible Citrus sinensis cv. ‘Newhall’ and its citrus canker-resistant bud mutation variety ‘Longhuitian’ (LHT) as materials. Through analysing the variances in leaf phenotypes between Newhall and LHT, as well as the variations in their transcriptional expression under Xanthomonas citri subsp. citri (Xcc) inoculation, our study concluded that LHT displays markedly greater resistance to Xcc compared to Newhall. Additionally, the spongy parenchyma of LHT leaves is significantly thicker than that of Newhall, and the stomatal number is significantly higher in LHT leaves, while the length and width of individual stomata in LHT leaves are significantly smaller than those in Newhall. RNA-seq analysis indicates that the differentially expressed genes between LHT and Newhall are involved in biotic stress-related biological processes, secondary metabolite biosynthesis, as well as phytohormone signalling pathways. Furthermore, significant differences were observed in reactive oxygen metabolism and phenylalanine metabolism pathways. The findings of our study provide data support for a deeper understanding of the citrus-Xcc interactions and offer valuable clues for unravelling citrus resistance to citrus canker.

description: In the fast evolving context of globalised higher education, increasing academic mobility requires constant adaptation from institutions. This paper focuses on intercultural enrichment programs, often perceived as mere “add ons” to study abroad, and usually designed as optional not-for-credit extracurricular offerings. We investigate how institutions can give more value to and deepen the intercultural learning of more students in spite of constraints of time and of formal curriculum during short-term study abroad experiences. Resulting from a close collaboration between academic and administrative staff based at different campuses, this paper provides a critical analysis of the benefits and challenges involved in developing co-curricular intercultural enrichment programs that support formal curriculum during study abroad. Practical recommendations are based on a transdisciplinary program developed in Italy by an Australian university that has branch campuses in different countries. We also discuss the “digitally enhanced” aspects of the program which facilitate the in-class activities.

description: We report the most comprehensive UBV(RI)_C observations of the bright, radially pulsating field stars SW And, DH Peg, CU Com, DY Peg. Long term variation has been found in the ultraviolet colour curves of SW And and DH Peg. We apply our photometric-hydrodynamic method to determine the fundamental parameters of these stars: metallicity, reddening, distance, mass, radius, equilibrium luminosity and effective temperature. Our method works well for SW And, CU Com and DY Peg. A very small mass 0.26+/-0.04 M_Sun of SW And has been found. The fundamental parameters of CU Com are those of a normal double-mode RR Lyrae (RRd) star. DY Peg has been found to have paradoxical astrophysical parameters: the metallicity, mass and period are characteristic for a high-amplitude Delta Sct star while the luminosity and radius place it in the group of RR Lyrae stars. DH Peg has been found to be peculiar: the definite instability in the colour curves towards ultraviolet, the dynamical variability of the atmosphere during the shocked phases suggests that the main assumptions of our photometric-hydrodynamic method, the quasi-static atmosphere approximation (QSAA) and the exclusive excitation of radial modes are probably not satisfied in this star. The fundamental parameters of all stars studied in this series of papers are summarized in tabular and graphical form.

Inference of dispersion measure from incoherent time-steady sources

description: Several recent papers have proposed schemes by which a dispersion measure, and hence electron column, could be obtained from a time-steady, incoherent radio source at a cosmological distance (such as an active galactic nucleus). If correct, this would open a new window on the distribution of intergalactic baryons. These schemes are based on the statistical properties of the received radiation, such as the 2- or 4-point correlation function of the received electric field, and in one case on the quantum nature of the electromagnetic field. We show, on the basis of general principles, that these schemes are not sensitive to dispersion measure (or have an extremely small signal-to-noise ratio), because (i) the classical 2-point correlation function is unaffected by dispersion; (ii) for a source with a large number of incoherently emitting electrons, the central limit theorem obliterates additional information in higher-order functions; and (iii) such an emitter produces a radiation density matrix that is equivalent to a statistical distribution of coherent states, which contains no information that is not already in the statistics of the classical waveforms. Why the proposed observables do not depend on dispersion measure (or have extremely tiny dependences) is discussed in detail.

description: HIV antibody was detected in 27 of 450 prisoners (6.0%), in a crosssectional study carried out in the major prison of Dire Daloia district, in eastern Ethiopia. Syphilis was found to be very common in the prisoners. Overall, 31.6% of the prisoners had a positive VDRL. The rate in prisoners who were HIV positive was 63% or 17 out of 27. A concurrent diagnosis of syphilis was strongly associated with HIV seropositivity. (Odd's ratio = 4.09). Recent admission to prison within the past three months was strongly associated with HIV positivity (Odd's ratio = 3.72); 21 of the 27 HIV positive prisoners had been in prison for less than three months. Factors found important in other studies on prisoners and AIDS, such as homos(3xuali ty and intravenous drug use were not found to be features of prisoners in Dire Dawa. Surprisingly, significant associations could not be proved between number of prostitute contacts or number of sexual contacts per month before prison and HIV positivity. Duration of residence in Dire Dawa town, trave l outside of Dire Dawa and number of l ong term sex partners before prison, were not found to be associated with HIV seropositivity. Likewise, no statistically significant correlation was found between HIV seropositivity and history of injections, dental extractions or immunizations in the past.

description: We study the abundance distributions of a sample of metal-rich barium stars provided by Pereira et al. (2011) to investigate the s- and r-process nucleosynthesis in the metal-rich environment. We compared the theoretical results predicted by a parametric model with the observed abundances of the metal-rich barium stars. We found that six barium stars have a significant r-process characteristic, and we divided the barium stars into two groups: the r-rich barium stars ($C_r>5.0$, [La/Nd]\,$<0$) and normal barium stars. The behavior of the r-rich barium stars seems more like that of the metal-poor r-rich and CEMP-r/s stars. We suggest that the most possible formation mechanism for these stars is the s-process pollution, although their abundance patterns can be fitted very well when the pre-enrichment hypothesis is included. The fact that we can not explain them well using the s-process nucleosynthesis alone may be due to our incomplete knowledge on the production of Nd, Eu, and other relevant elements by the s-process in metal-rich and super metal-rich environments (see details in Pereira et al. 2011).

Tradurre le emozioni della DDR a trent’anni dalla caduta del muro. Als wir träumten di Clemens Meyer a confronto con Eravamo dei grandissimi a cura di Roberta Gado e Riccardo Cravero
Creators: name: Ballestracci, Sabrina
name: Palilla, Giovanni
Publisher: name: Firenze University Press
Year: 2018
Subjects: DDR; memory; emotions; realia; literary tranlsation

description: Following the footsteps of present Italian and German studies, the purpose of this paper is to examine the typical words and expressions of the DDR contained in Als wir träumten by Clemens Meyer (2006) – a novel where the protagonist evokes the DDR, a historic reality no longer existing – and to compare them with the Italian translation entitled Eravamo dei grandissimi (2016). Even if in the first instance the focus is on the lexicon, the goal of this research is to highlight the emotional charge of the “language of the DDR”, going beyond mere linguistic and lexical aspects, taking into consideration the cultural dimension of this linguistic variety. This paper aims to determine the main strategies used by the translators in the specific cases analysed, with the aim of reflecting on the concept of translation as a means to transmit both the cultural heritage and the emotional dimension.

Politiche di traduzione e pseudotraduzioni nella Turchia repubblicana. “Memorie del corvo zoppo”: una pseudotraduzione di Pitigrilli/Avni İnsel
Creators: name: Bertuccelli, Fulvio
Publisher: name: Firenze University Press
Year: 2018
Subjects: Avni İnsel; Pitigrilli; translation and pseudotranslation in Turkey; Turkish Humanism

description: This article is an outline of the cultural and literary atmosphere of the 1940s, invoving a consideration of Turkish translation policy in the country after Atatürk’s death focusing on two apparently disconnected topics i.e. cultural planning policies and pseudotranslation. Thus, I will offer a brief overview of the Kemalist reforms, which deeply affected the cultural sphere of the country, such as the founding of the Translation Bureau (1940) considering the importance of the quest for a “Turkish Renaissance” behind its activities. Then, my analysis will turn to the practice of pseudotranslation, focusing on a specific case i.e. Topal Karganın Hatıraları (Memories of the Crippled Crow) which was published and presented as the Italian writer Pitigrilli’s last work in 1946.

L’essenziale. Ovvero, l’immagine del limite in Jon Krakauer e Bruce Chatwin
Creators: name: Gaudio, Paola
Publisher: name: Firenze University Press
Year: 2018
Subjects: adventure fiction; Bruce Chatwin; Jon Krakauer; photography; travel literature

description: This paper analyses how Into the Wild, Into Thin Air, and In Patagonia represent, each in its own way, an image of the limit – this limit being not only visual but also existential. These stories take place in remote places where the protagonists of the narratives cross the borders of everyday life in order to discover extreme, unexplored surroundings. If the intent of capturing the experience of survival in the Alaskan wilderness finds its objective correlative in Chris McCandless’ camera shots, in Into Thin Air it is the images of both geographical and physical limits that accompany the narrative. In Chatwin’s travelogue, on the other hand, the awareness of existing at the edge of the Earth is embodied in its narrative structure where digressions are more frequent than linear progression.

Subjects: Big Data Analytics (BDA), Risk Management, Credit Risk Modeling, Fraud Detection, Market Prediction, Data Privacy & Quality

description: This study is on enhancing risk management in financial institutions through big data analytics.  It delves into the impact of big data analytics on risk management practices within financial institutions, focusing on how these advanced techniques contribute to improving both the accuracy and timeliness of risk prediction models. By employing a comprehensive survey methodology, the research collected insights from 217 industry professionals to assess the effectiveness of big data analytics in enhancing risk management. The study reveals that a substantial proportion of respondents recognize big data analytics as a powerful tool for refining the precision of risk prediction models. Among the tools assessed, Apache Hadoop and Apache Spark are highlighted as particularly effective in processing and analyzing large datasets. Despite the overall positive assessment, the study identifies several persistent challenges, including issues related to data quality, integration complexities, and the high costs of implementation. To address these challenges, the study recommends several strategies: enhancing data quality and integration processes, investing significantly in employee training and development, and implementing robust data security measures to protect sensitive information. These findings offer actionable insights for financial institutions aiming to leverage big data analytics to optimize their risk management practices. They underscore both the significant benefits of these technologies and the critical strategies required for overcoming implementation challenges and achieving successful outcomes in risk management.
The cultural and historical legacy of classical antiquity in Rudolf Borchardt’s essay on Virgil’s Aeneid
Creators: name: Giacoponi, Liliana
Publisher: name: Firenze University Press
Year: 2018
Subjects: Aeneid; Borchardt; crisis; rebirth; Virgil

description: In Germany Virgil’s work had long been considered a fake re-interpretation of Greek models, lacking originality and life: Virgil himself was seen as a mere servant of power. This essay explores how Borchardt sought to undermine the accepted interpretation of the author of the Aeneid. It will show that while reinterpreting Virgil’s legacy, Borchardt set out a completely new vision of his work and how this vision differs from the fascist exaltation of Virgil. It will focus on Borchardt’s inference that the Aeneid is at the same time a message from the past and a message of hope for the future. It discusses to what extent examining the present through Virgil’s work, he endeavours to escape the disruptive power of the crisis of the 1930s. Finally, it will expose how the author finds an emblematic alter-ego in the character of the exiled Aeneas.

Il re nella Kādambarī. Regalità, Fato e Fortuna nella Kādambarī di Bāṇa
Creators: name: Gnoato, Maria Luisa
Publisher: name: Firenze University Press
Year: 2018
Subjects: Bāṇa; fate; fortune; Kādambarī; royalty

description: After some observations about the importance attributed to the king in the most authoritative texts of Brahmanic tradition, this essay illustrates the role of the sovereign in Kādambarī, the famous novel by Bāṇa. The king embodies the force that permeates and sustains the whole world. He is the first principle of the universe and thus the axis mundi. Extremely problematic is the relationship betweenindividual value and “fate” (karman), to which the very sovereign is subject, although he himself is defined as the “source of fortune”. The king’s value depends on his firm dedication to Dharma and on his ability to lead all creatures to consciousness of their own sacredness. The protagonists of this novel are linked by religious merit, the only element that can change fate.

description: The main goal of this work is to a have a new neutral hydrogen HI supershell candidates catalog to analyze their spatial distribution in the Galaxy and to carry out a statistical study of their main properties.}{This catalog was carried out making use of the Leiden-Argentine-Bonn (LAB) survey. The supershell candidates were identified using a combination of two techniques: a visual inspection plus an automatic searching algorithm. Our automatic algorithm is able to detect both closed and open structures. A total of 566 supershell candidates were identified. Most of them (347) are located in the second Galactic quadrant, while 219 were found in the third one. About $98 \, \%$ of a subset of 190 structures (used to derive the statistical properties of the supershell candidates) are elliptical with a mean weighted eccentricity of $0.8 \pm 0.1$, and $\sim 70 \,\%$ have their major axes parallel to the Galactic plane. The weighted mean value of the effective radius of the structures is $\sim$ 160 pc. Owing to the ability of our automatic algorithm to detect open structures, we have also identified some "galactic chimney" candidates. We find an asymmetry between the second and third Galactic quadrants in the sense that in the second one we detect structures as far as 32 kpc, while for the 3rd one the farthest structure is detected at 17 kpc. The supershell surface density in the solar neighborhood is $\sim$ 8 kpc$^{-2}$, and decreases as we move farther away form the Galactic center. We have also compared our catalog with those by other authors.

description: Saturn's inner B-ring and its C-ring support wavetrains of contrasting amplitudes but with similar length scales, 100-1000 km. In addition, the inner B-ring is punctuated by two intriguing `flat' regions between radii 93,000 km and 98,000 km in which the waves die out, whereas the C-ring waves coexist with a forest of plateaus, narrow ringlets, and gaps. In both regions the waves are probably generated by a large-scale linear instability whose origin lies in the meteoritic bombardment of the rings: the ballistic transport instability. In this paper, the third in a series, we numerically simulate the long-term nonlinear evolution of this instability in a convenient local model. Our C-ring simulations confirm that the unstable system forms low-amplitude wavetrains possessing a preferred band of wavelengths. B-ring simulations, on the other hand, exhibit localised nonlinear wave `packets' separated by linearly stable flat zones. Wave packets travel slowly while spreading in time, a result that suggests the observed flat regions in Saturn's B-ring are shrinking. Finally, we present exploratory runs of the inner B-ring edge which reproduce earlier numerical results: ballistic transport can maintain the sharpness of a spreading edge while building a `ramp' structure at its base. Moreover, the ballistic transport instability can afflict the ramp region, but only in low-viscosity runs.
