Publisher: name: tourismos
Year: 2009

description: Tourism is one of the first services sectors to adapt and use Information and Communication Technology (ICT) for promoting its services. ICT enable travelers to access reliable and accurate information, as well as to make reservations in a fraction of the time and the cost. The objective of this work is to measure the impact of ICT on the tourism sector growth. Assuming that the increase of etourism sector depends on the increase in tourism demand and internet penetration, we examine the case of all Mediterranean EU member countries, and forecast the growth of online tourism services.

description: We establish a number of foundational results on Poincaré spaces which result in several applications. One application settles an old conjecture of C.T.C. Wall in the affirmative. Another result shows that for any natural number n, there exists a finite CW pair $(X,Y)$ satisfying relative Poincaré duality in dimension n with the property that $Y$ fails to satisfy Poincaré duality. We also prove a relative version of a result of Gottlieb about Poincaré duality and fibrations.

description: In this article we present a method to generate analytic expressions for the integral coefficients of loop amplitudes using numerical evaluations only. We use high-precision arithmetic to explore the singularity structure of the coefficients and decompose them into parts of manageable complexity. To illustrate the usability of our method we provide analytical expressions for all helicity configurations of the colour-ordered six-point gluon amplitudes at one loop with a gluon in the loop.

 Morphometry: —a.a.: 7–14 μm; p.a.: 6–11 μm.
 LM: —Cells are united in short straight chains of 3–9 cells (Fig. 133). In valve view cells are generally circular, in girdle view rectangular with sharp corners. One chloroplast is present per cell (Fig. 134). The setae originate at the valve corners and fuse immediately at the chain margin without a basal part. The apertures are slit-shaped and very narrow or almost absent (Fig. 134). There are two types of intercalary setae: the common ones and special ones (Fig. 133) showing a different thickness and orientation. Special setae diverge at an angle of about 45° from the chain axis and then curve towards the terminal part of the chain. They become thicker after some length and then taper again towards their ends. Terminal setae extend almost parallel to the chain axis diverging in a U-shaped curve (Fig. 133). All setae of a chain lie in the apical plane.
 EM: —The valve has a central annulus from which a weak pattern of radiating costae branches dichotomously towards the valve margin (Fig. 135). The area between costae is irregularly perforated with densely scattered small poroids. Valve is face flat or slightly convex, and the mantle is high with a slight constriction near the edge (Fig. 136). Between the valve face and the mantle in most cases there is no discernible marginal ridge, and only sometimes the extensions of the hyaline rim are fused between sibling cells at each edge of the aperture (Fig. 136). Terminal cells have a labiate-shaped rimoportula with a small projection on the outside (Figs 137, 138) Special setae are strongly silicified and ornamented with thick shark fin-shaped spines (Fig. 139). Common intercalary setae have four to five longitudinal or slightly spiral rows of rectangular poroids as well as spines spirally arranged around the seta (Fig. 140). Girdle bands are ornamented with transverse parallel ribs (Fig. 141).
 Distinctive features: —General shape of the chain, cells with very sharp corners and narrow apertures, setae widely diverging in apical plane, with special thicker intercalary setae.

description: Fast and scalable Content-Based Image Retrieval using visual features is required for document analysis, Medical image analysis, etc. in the present age. Convolutional Neural Network (CNN) activations as features achieved their outstanding performance in this area. Deep Convolutional representations using the softmax function in the output layer are also ones among visual features. However, almost all the image retrieval systems hold their index of visual features on main memory in order to high responsiveness, limiting their applicability for big data applications. In this paper, we propose a fast calculation method of cosine similarity with L2 norm indexed in advance on Elasticsearch. We evaluate our approach with ImageNet Dataset and VGG-16 pre-trained model. The evaluation results show the effectiveness and efficiency of our proposed method.

description: Complex networks exhibit a wide range of collective dynamic phenomena, including synchronization, diffusion, relaxation, and coordination processes. Their asymptotic dynamics is generically characterized by the local Jacobian, graph Laplacian or a similar linear operator. The structure of networks with regular, small-world and random connectivities are reasonably well understood, but their collective dynamical properties remain largely unknown. Here we present a two-stage mean-field theory to derive analytic expressions for network spectra. A single formula covers the spectrum from regular via small-world to strongly randomized topologies in Watts-Strogatz networks, explaining the simultaneous dependencies on network size N, average degree k and topological randomness q. We present simplified analytic predictions for the second largest and smallest eigenvalue, and numerical checks confirm our theoretical predictions for zero, small and moderate topological randomness q, including the entire small-world regime. For large q of the order of one, we apply standard random matrix theory thereby overarching the full range from regular to randomized network topologies. These results may contribute to our analytic and mechanistic understanding of collective relaxation phenomena of network dynamical systems.

description: We consider a TFT on the product of a manifold with an interval, together with a topological and a non-topological boundary condition imposed at the two respective ends. The resulting (in general higher gauge) field theory is non-topological, with different choices of the topological conditions leading to field theories dual to each other. In particular, we recover the electric-magnetic duality, the Poisson-Lie T-duality, and we obtain new higher analogues thereof.

Subjects: subject: Space Physics (physics.space-ph)
subject: FOS: Physical sciences

description: A new scalar measure of the gyrotropy of a pressure tensor is defined. Previously suggested measures are shown to be incomplete by means of examples for which they give unphysical results. To demonstrate its usefulness as an indicator of magnetic topology, the new measure is calculated for electron data taken from numerical simulations of magnetic reconnection, shown to peak at separatrices and X-points, and compared to the other measures. The new diagnostic has potential uses in analyzing spacecraft observations and so a method for calculating it from measurements performed in an arbitrary coordinate system is derived.

description: The behavior of many Bayesian models used in machine learning critically depends on the choice of prior distributions, controlled by some hyperparameters that are typically selected by Bayesian optimization or cross-validation. This requires repeated, costly, posterior inference. We provide an alternative for selecting good priors without carrying out posterior inference, building on the prior predictive distribution that marginalizes out the model parameters. We estimate virtual statistics for data generated by the prior predictive distribution and then optimize over the hyperparameters to learn ones for which these virtual statistics match target values provided by the user or estimated from (subset of) the observed data. We apply the principle for probabilistic matrix factorization, for which good solutions for prior selection have been missing. We show that for Poisson factorization models we can analytically determine the hyperparameters, including the number of factors, that best replicate the target statistics, and we study empirically the sensitivity of the approach for model mismatch. We also present a model-independent procedure that determines the hyperparameters for general models by stochastic optimization, and demonstrate this extension in context of hierarchical matrix factorization models.

Digital preservation

description: This study explored the perceptions of food bloggers on digital preservation of their blogs through an anonymous, web-based survey. It also examined if the blog format changes authenticity. Survey questions asked for data on blogging behavior, technology and preservation and deletion, editing and loss. The survey was shared through Facebook pages and groups, discussion boards and forums, Twitter and Tumblr. This study looked at how bloggers view their blogs long-term. The study assessed if bloggers view their content as possessing enduring value. Furthermore, it ascertained if the participants have taken steps to preserve their blogs. The majority of the respondents were reasonably confident in their technical skills for blog maintenance. Despite this, half were not using any strategy to save their blog. Respondents questioned the enduring value of their blogs. Some sub-group differences found between hobby bloggers and for profit bloggers. In addition, issues of authenticity were not conclusively determined.

description: By using the conserved currents in the bulk space-time, we study dynamical holographic systems and the relation between thermodynamical and dynamical stability of such systems. In particular, in the probe limit a generalized free energy is defined with the property of monotonic decreasing in dynamic processes. It is then shown that the (absolute) thermodynamical stability implies the dynamical stability, while the linear dynamical stability implies the thermodynamical (meta-)stability. The holographic superfluid is taken as an example to illustrate our general formalism, where the dynamic evolution of the system in contact with a particle source is clarified by theoretical investigation and numerical verification. The case going beyond the probe limit is also discussed.

description: The objective of this research paper is to study the behavior of senior citizens regarding these e-banking services in Uttarakhand. As educated senior citizens are the major segment using banking services it becomes necessary to study the awareness, usage, ease of using, and satisfaction level of e-banking services among them. The researcher has used a descriptive research design and non-probability convenience sampling method for this study. The survey method is used to collect the data from 156 respondents by using a well-structured questionnaire. The findings revealed that the technological enhancements and promotion of e-banking services by banks haven’t added much pleasure to the interest of senior citizens. So, this research will be beneficial for the banking system to satisfy senior citizens' needs through e-banking.

Our approach is based on the Nourdin-Viens formula and a stochastic version of Wazewski's theorem on the positivity of the components of a solution to an ODE. Furthermore, we apply our results to stochastic gene expression; namely, we estimate the density of the law of the amount of protein generated by a gene in a gene regulatory network.

description: Reisen nach Italien im späten 18. und frühen 19. Jahrhundert sind von einem Erwartungsbruch geprägt, der durch mitgebrachte Vorkenntnisse einer prachtvoll imaginierten Antike mit dem Vorfinden von Ruinenlandschaften hervorgerufen wird. Die daraus entstehende Frustration entlädt sich in unterschiedlichen literarischen Bewältigungsstrategien, die sich jeweils an dem antiken Vorbild, dem vorgefundenen Abbild oder dem durch übermäßige Idealisierung und gesteigerte Eigenwahrnehmung hervorgebrachten Zerrbild orientieren. Ein beliebtes Mittel ist die Ironie, welche sich sowohl in der scherzhaften, mit antikem Wissen verwobenen Beschreibung der gesehenen Landschaften niederschlägt, als auch in der offensichtlichen Ablehnung des Gesehenen, ohne sich jedoch für diesen Zustand verantwortlich zu fühlen und daran zu verzweifeln. So sind auch Parodie und Satire vertreten, wobei die Frustration des Autors zum wahren Gesicht der Landschaft wird. Eine andere Möglichkeit birgt die rationale Anschauung: Hierbei kann mit dem „Blick ins Buch“ das antike Vorbild vor das tatsächlich Gesehene, das Abbild, geschoben werden. Vertreten ist jedoch auch das Gegenteil, indem das Vorhandene wertfrei beschrieben wird, was die Präsenz antiker Quellen zwar zulässt, aber nicht mehr benötigt. Der Aufsatz zeigt entlang von Autoren wie Charles de Brosse, Joseph Addison, sowie Baron Aigustin Creuzé de Lesser und Johann Jakob Volkmann diese Italienerfahrung anhand von Beispielen aus Briefen, Tagebüchern und Reiseberichten.

description: The University of North Carolina at Chapel Hill Library has used Libraryh3lp as its chat reference platform for approximately six years. In that time, the placement of chat widgets has expanded to include library web pages, Articles+, the catalog, and Serials Solutions pages. One important location remained to explore: placement of a chat widget in library-licensed databases. If a user is in a database, they would currently need to open a new browser tab and navigate back to the library's Contact Us page to initiate a chat. In an effort to meet users closer to their point of need, a widget was embedded in UNC's databases licensed from EBSCOhost. After a trial period, the resulting chat logs and transcripts were analyzed. By embedding the widget in databases, where a good portion of research is performed, the number and overall proportion of research-related chat questions increased.

description: In seinem Roman „Julie oder die neue Héloïse“ (1761) schildert Jean-Jaques Rousseau Landschaften, die im Garten der Protagonistin, Julies Elysium, gipfeln. Die Beschreibungen beruhen auf dem Vorbild englischer Landschaftsgärten, welche sich durch ihre vorgetäuschte Naturbelassenheit auszeichnen, ohne dass die „Hand des Gärtners“ zu sehen ist. Als locus amoenus wird der Garten bei Rousseau zum moralischen Schutzraum, ermöglicht Selbstfindung und Heilung und dient als Orientierung für das eigene Handeln. Umgekehrt spiegelt sich die Lesart des Romans in zeitgenössischen Gartenanlagen wider. Im eigens nach dem Vorbild Rousseaus angelegten Park von Ermenonville kreiert sein Besitzer René Louis Marquis de Girardin eine lesbare Landschaft, die veredelt sowie mit Inschriften und Zitaten versehen zum durchschreitbaren Gedicht wird. Dies findet seinen Höhepunkt als Rousseau selbst zum Inventar des Gartens werden soll. Der Tod des Dichters wenige Monate nach seinem Eintreffen in Ermenonville führt zu seiner Beisetzung auf der Pappelinsel, welche wiederum in spätere Landschaftsgärten übernommen wird.

description: One of the more widely advocated solutions for slowing down the spread of COVID-19 has been automated contact tracing. Since proximity data can be collected by personal mobile devices, the natural proposal has been to use this for automated contact tracing providing a major gain over a manual implementation. In this work, we study the characteristics of voluntary and automated contact tracing and its effectiveness for mapping the spread of a pandemic due to the spread of SARS-CoV-2. We highlight the infrastructure and social structures required for automated contact tracing to work. We display the vulnerabilities of the strategy to inadequate sampling of the population, which results in the inability to sufficiently determine significant contact with infected individuals. Of crucial importance will be the participation of a significant fraction of the population for which we derive a minimum threshold. We conclude that relying largely on automated contact tracing without population-wide participation to contain the spread of the SARS-CoV-2 pandemic can be counterproductive and allow the pandemic to spread unchecked. The simultaneous implementation of various mitigation methods along with automated contact tracing is necessary for reaching an optimal solution to contain the pandemic.

description: Although spin is a core property in fermionic systems, its symmetry can be easily violated in a variational simulation, especially when strong correlation plays a vital role therein. In this study, we will demonstrate that the broken spin-symmetry can be restored exactly in a quantum computer, with little overhead in circuits, while delivering additional strong correlation energy with the desired spin quantum number. The proposed scheme permits drastic reduction of a potentially large number of measurements required to ensure spin-symmetry by employing a superposition of only a few rotated quantum states. Our implementation is universal, simple, and, most importantly, straightforwardly applicable to any ansatz proposed to date.

CREATING UGC AREAS ON OFFICIAL DESTINATION WEBSITES: IS THERE A RECIPE FOR SUCCESS? AN INSIGHT THROUGH NETNOGRAPHIC RESEARCH
Creators: name: Osti, Linda
Publisher: name: tourismos
Year: 2009

description: An analysis of the existing literature has demonstrated the importance of word of mouth as a source of information for potential tourists and service consumers. The growth of the Internet and interactive websites has lead to the creation of online communities that serve as points of reference for word of mouth and in particular for independent, personal and experiential information. Recent articles have noted the growing interest of tourism companies and destinations to include UGC areas in their official websites to provide their users with these types of information and interactivity among each others. However, so far little research has been performed on the success factors of online communities. This paper wants to create a platform for further research on the topic. If destinations want to boost visits to their websites through UGS areas and create a “buzz” through positive word of mouth, it is necessary to know the correct ingredients for success. Some of these ingredients have been discovered through a netnographic analysis of an Italian virtual mountaineering community. The analysis has shown that some of the most important issues when creating online communities are the reliability of information, the ease of finding information and creating threads and posts, the constant appearance of interesting threads and discussions, the respect for other members, the passion of all of the active users for the same topics and a certain homogeneity within the users.

description: This paper repeated a 2004 user study of the manuscripts collections at the University of North Carolina at Chapel Hill to assess the research practices of the university's scholars of the American South. The methodology was changed from a paper-based survey to use of a commercial online survey company, which offered the new study numerous affordances and advantages over the old. It eases making user studies a regularized archival task, an important aspect of user studies. Changing distribution methodology from mailed surveys to a mass email announcement and converting the survey from one media to another offered valuable lessons regarding online survey research.

description: The Functionalized Cahn-Hilliard equation has been proposed as a model for the interfacial energy of phase-separated mixtures of amphiphilic molecules. We study the existence of a nonnegative weak solutions of a gradient flow of the Functionalized Cahn-Hilliard equation subject to a degenerate mobility M(u) that is zero for u<=0. Assuming the initial data u0(x) is positive, we construct a weak solution as the limit of solutions corresponding to nondegenerate mobilities and verify that it satisfies an energy dissipation inequality.

In this framework, we demonstrate that the spectral method exhibits universal detectability, irrespective of the value of the resolution parameter, as long as the graph is partitioned. Furthermore, we show that when the resolution parameter is sufficiently small, a first-order phase transition occurs, resulting in the graph being unpartitioned.

Copyright

description: Many libraries, particularly large academic libraries, have begun major digitization projects in order to make library material much more widely available.  However, many works that might otherwise be candidates for digitization are protected by copyright.  While this does not completely bar a work from being digitized, it becomes a much more complicated process if permission is required.  This research studies how academic library digitization projects have addressed copyrighted materials.  Librarians and publishers were interviewed to understand their perspective on copyright and to determine the best practices for locating and contacting copyright holders.  Overall, there is no one best technique for finding copyright holders, but there are ways that librarians can expedite the process, such as by developing a good workflow at the outset and consulting with administration.  Overall, institutions have been successful in incorporating copyright items into a digitization project, although a heavy time investment is involved.

description: We show that for every integer $n\geq 1$ there exists a graph $G_n$ with $(1+o(1))n$ vertices and $n^{1 + o(1)}$ edges such that every $n$-vertex planar graph is isomorphic to a subgraph of $G_n$. The best previous bound on the number of edges was $O(n^{3/2})$, proved by Babai, Chung, Erdős, Graham, and Spencer in 1982. We then show that for every integer $n\geq 1$ there is a graph $U_n$ with $n^{1 + o(1)}$ vertices and edges that contains induced copies of every $n$-vertex planar graph. This significantly reduces the number of edges in a recent construction of the authors with Dujmović, Gavoille, and Micek.

description: There are several combinatorial methods that can be used to produce type A Demazure characters (key polynomials). The alcove path model of Lenart and Postnikov provides a procedure that inputs a semistandard tableau $T$ and outputs a saturated chain in the Bruhat order. The final permutation in this chain determines a family of Demazure characters for which $T$ contributes its weight. Separately, the right key of $T$ introduced by Lascoux and Schützenberger also determines a family of Demazure characters for which $T$ contributes its weight. In this paper we show that the final permutation in the chain produced by the alcove model corresponds bijectively to the right key of the tableau. From this it follows that the generating sets for the Demazure characters produced by these two methods are equivalent.

 Description: —a.a.: 15–35 μm; p.a.: 16–30 μm.
 LM: —Cells are united in long, curved or helical chains (Fig. 160). Cells are elliptical in valve view and rectangular in girdle view. In each cell there is a single lobed chloroplast (Fig. 161). The valve face is concave with four protuberances situated along the valve margin, two per each side of the valve positioned close to the valve apices. Each protuberance fuses with the corresponding one on the sibling valve (Fig. 161) forming a narrow oval aperture which is shorter than the cell apical axis (Fig. 161). Intercalary setae originate from the valve corners and fuse immediately without basal part. In girdle view all setae are curved towards the same, convex side of the chain (Fig. 160) while in valve view they are all bent to one side of the apical axis.
 Distinctive features: —Chains curved in the pervalvar plane. Oval aperture narrower than in the very similar species C. curvisetus.

description: The paper addresses the relationship between faculty status and job satisfaction among academic law librarians in the United States. A review of relevant refereed literature in both academic librarianship generally and law librarianship specifically is provided as background. The paper culminates with the results and analysis of a twenty-item survey sent electronically by the author to academic law librarians across the country gauging their current faculty status and aspects of their job satisfaction. The results support the hypothesis posed in the paper: that faculty status does relate favorably with and makes a difference in job satisfaction among academic law librarians.

description: We investigate the spectral instability of a $2π/κ$ periodic Stokes wave of sufficiently small amplitude, traveling in water of unit depth, under gravity. Numerical evidence suggests instability whenever the unperturbed wave is resonant with its infinitesimal perturbations. This has not been analytically studied except for the Benjamin--Feir instability in the vicinity of the origin of the complex plane. Here we develop a periodic Evans function approach to give an alternative proof of the Benjamin--Feir instability and, also, a first proof of spectral instability away from the origin. Specifically, we prove instability near the origin for $κ>κ_1:=1.3627827\dots$ and instability due to resonance of order two so long as an index function is positive. Validated numerics establishes that the index function is indeed positive for some $κ<κ_1$, whereby there exists a Stokes wave that is spectrally unstable even though it is insusceptible to the Benjamin--Feir instability. The proofs involve center manifold reduction, Floquet theory, and methods of ordinary and partial differential equations. Numerical evaluation reveals that the index function remains positive unless $κ=1.8494040\dots$. Therefore, we conjecture that all Stokes waves of sufficiently small amplitude are spectrally unstable. For the proof of the conjecture, one has to verify that the index function is positive for $κ$ sufficiently small.

description: Recently there has been a steady increase in the number of non-white students, especially
Latino students in southeast school systems. This study determines whether this
population is being successfully supported in their school library by asking two
questions: (1) Are culturally relevant resources that are based on award winning
nominations available to the Latino population within each school library? (2) What
facilitators and barriers exist for the School Librarians supporting this population?
This study analyzed the prevalence of Latino book award titles in three southeast school
libraries, and conducted interviews with their school librarians. Data collected was based
on a list of book titles that have received one of the three awards: the Pura Belpré,
Americas, or Tomás Rivera award. Then, a content analysis was conducted from the
responses of three phone interviews, which revealed the facilitators and barriers they
encountered to support this population.
title: The Call: a cinematic encounter with nonhuman animal characters and their worlds
Creators: name: Czatkowska, Emilia
Publisher: name: University of Kent
Year: 2022

description: In this thesis I bring the nonhuman animal character into the discourse of Film Studies, from which they have by and large been excluded. Including the nonhuman animal character helps to expand film theoretical discussions that have normally been restricted to human characters. In order to address this omission, I introduce and conceptualise two notions: the nonhuman animal call and the cinematic call on behalf of the nonhuman animal. The nonhuman animal call is an umbrella term for a variety of nonhuman animal expressions. Some of such expressions are based on five basic senses on which humans rely, but the nonhuman animal call also includes senses not present in humans. The division of calls is non-hierarchical. The aim of introducing the nonhuman animal call is to emphasise nonhuman animal performance and expression as intentional, meaningful, and important for the film in which the nonhuman animal appears, and thereby opening up new interpretative possibilities which take the nonhuman animal perspective into consideration. The cinematic call on behalf of the nonhuman animal denotes film techniques, which, under certain conditions, can provide space for nonhuman animal calls to manifest themselves in the film, or help clarify nonhuman animal calls which the spectator might find unintelligible, or strengthen the nonhuman animal call's affective impact on the spectator. Cinematic calls on behalf of the nonhuman animal character are versatile, that is, they are not limited to a particular genre or tradition of filmmaking. Therefore, the reflection on the conditions which such film techniques must fulfil to be considered as cinematic calls invites a productive dialogue across genres and aesthetic traditions. As a result of such a reflection, this thesis offers some guidelines for film production and film analysis that are, on the one hand, more mindful of the nonhuman animal characters, and on the other hand, take into account diverse types of spectators, and the ways in which to appeal to them to invite a reflection on the nonhuman animal condition. The nonhuman animal call and the cinematic call on behalf of the nonhuman animal character are, therefore, practical, didactic, and analytic tools that can be applied in order to render the Film Studies discourse as well as film production and reception more animal-oriented.

description: A wide range of n- and p-type doping levels in GaAs layers grown by chemical beam epitaxy is achieved using H$_{2}$-diluted DTBSi and CBr$_{4}$ as gas precursors for Si and C. We show that the doping level can be varied by modifying either the concentration or the flux of the diluted precursor. Specifically, we demonstrate carrier concentrations of 6$\times$10$^{17}$-1.2$\times$10$^{19}$ cm$^{-3}$ for Si, and 9$\times$10$^{16}$-3.7$\times$10$^{20}$ cm$^{-3}$ for C, as determined by Hall effect measurements. The incorporation of Si and C as a function of the flux of the corresponding diluted precursor is found to follow, respectively, a first and a fourth order power law. The dependence of the electron and hole mobility values on the carrier concentration as well as the analysis of the layers by low-temperature (12 K) photoluminescence spectroscopy indicate that the use of H$_{2}$ for diluting DTBSi or CBr$_{4}$ has no effect on the electrical and optical properties of GaAs.

 Morphometry: —a.a.: 14–21 μm; p.a.: 5–14 μm.
 LM: —Cells are united in usually long chains that are very strongly twisted around the chain axis in such a way that some sibling valves position themselves perpendicular to each other (Figs 173–175). In valve view cells are broadly elliptical and compressed in the transapical direction, in girdle view they are rectangular with rounded valve corners. Each cell contains a single parietal plate-like chloroplast positioned around the girdle (Fig. 176). The valve face is flat or slightly convex; the mantle is low and sometimes constricted near the margin, girdle equidimensional or higher than the mantle. Long and thin setae originate within the valve margin and slightly direct outwards forming a short basal part, and then cross slightly inside or at the chain margin (Fig. 175). Apertures are hexagonally shaped. Intercalary setae are generally oriented more or less perpendicularly to the chain axis or appear slightly curved (Fig. 173). In valve view they diverge at an equal angle (30–45°) from the apical plane. Terminal setae are thick like the intercalary ones and extend almost parallel to the colony axis in a U-shaped curve (Fig. 173).
 EM: —The valve has a central hyaline annulus from which extends a complex pattern of densely distributed costae, branching dichotomously towards the valve margin, sometimes forming small dots (Figs 177, 178). The marginal ridge does not have a prominent rim; it is only observable as a thickened edge between the valve face and the mantle. Girdle bands are adorned with transverse fine costae and a slightly thickened longitudinal rib near one edge (Fig. 181). A conspicuous character found in this species is the presence of a large elongated pore on the proximal part of the setae, right after the crossing point (Figs 178–180). Setae are circular in cross-section, ornamented with very small spines and poroids spirally positioned along the seta length (Fig. 182).
 Distinctive features: —Very strong torsion of the chain. Large elongated pore on the proximal part of the seta.
