The Early Byzantine Domed Basilicas of West Asia Minor, An essay in Graphic Reconstruction
Get PDFThis paper investigates the methodology employed in the recent survey and reconstruction of the major Early Byzantine domed churches of west Asia Minor. This involved both the documentation of construction details as well as their interpretation by reference to coeval monuments elsewhere. Focusing on this methodology, the author explores techniques of graphic recording and the theoretical framework within which parallels with other buildings can inform the work of reconstruction. The detailed examination of two case studies illustrates the way in which seemingly random scraps of testimony were interpreted to provide evidence for the missing superstructure of the churches. These case studies also serve to explore the adaptation of the methodology to sites with different characteristics and help to assess the credibility of the resulting graphic reconstructions

No full textAuthor self-citation in orthodontics is associated with author origin and gender.
Get PDFBACKGROUND
The aims of this bibliometric study were to determine author self-citation trends in high-impact orthodontic literature and to investigate possible association between self-citation and publication characteristics.
METHODS
Six orthodontic journals with the highest impact factor as ranked by 2017 Journal Citation Reports were screened for a full publication year (2018) for original research articles, reviews, and case reports. Eligible articles were scrutinized for article and author characteristics and citation metrics. Univariable and multivariable negative binomial regression was used to examine associations between self-citation incidence and publication characteristics.
RESULTS
Medians for author self-citation rate of the most self-citing authors and self-citations were 3.03% (range 0-50) and 1 (range 0-19), respectively. In the univariable analysis, there was no association between self-citation counts and study type (P = 0.41), article topic (P = 0.61), number of authors (P = 0.62), and rank of authors (P = 0.56). Author origin (P = 0.001), gender (P = 0.001) and journal (P = 0.05) were associated with self-citation counts and in the multivariable analysis only origin and gender remained strong self-citation predictors. Asian authors and females self-cited significantly less often than all other regions and male authors.
CONCLUSIONS
Authors in orthodontics do not self-cite at a frequency that suggests potential citation manipulation. Author origin and gender were the only variables associated with citations counts. More bibliometric research is necessary to draw solid conclusions about author self-citation trends in orthodontic literature

(2013: 103).</p> <p>SHELL DIMENSIONS</p> <p>– Karpathos Island: (n = 465) H 6.05–12.6 mm (mean = 9.86 mm); D 9.22–18.5 mm (mean = 14.52 mm); W 45/8–6 (mean = 54/s).</p> <p>– Saria Island: (n = 38) H 7.65–11.05 mm (mean = 9.43 mm); D 11.94–15.48 mm (mean = 14.04 mm); W 5–57/8 (mean = 54/s).</p> <p>Most of the shells have one or rarely two growth interruptions.</p> <p>GENITALIA (Fig. 2D, F). The inner structure of the reproductive system is given here for the first time (Fig. 2F). Flagellum very long, twice the length of epiphallus. Epiphallus becomes thicker closer to the penis. Penial retractor attached in the middle of the epiphallus. Penis less than half the length of the epiphallus, clavate, thicker and quite distinct at its junction with the epiphallus. Inside the penis there is a very short heart-shaped papilla, which seems globular from its rear side. In some specimens, the penial papilla is depressed in the distal edge causing it to be even shorter and less globular. Epiphallic pore starts with a V-shaped slot and opens in the slit that divides the upper side of the papilla. Inner penial walls have some short vertical ridges (Fig. 2F). Vas deferens slender. Vagina as thick as the penis and half to one third of its length. The base of the duct of the gametolytic gland is as broad as the penis and thick-walled and together with the distal part of the vagina they form a bump. Inside the thickened base of the duct there are slender longitudinal ridges (Fig. 2F). Free oviduct as long as the penis and half the width of the base of the duct of the gametolytic gland. At its junction with the duct, it forms a bump. Gametolytic gland globular.</p> Remarks <p> The shell measurements provided here have a wider range than those given by Bank <i>et al</i>. (2013) and are closer to the actual shell diversity of the subspecies due to the large number of studied specimens. It is the first time that <i>M. n. conciliatrix</i> is mentioned from the island of Saria, while Vardinoyannis (1994) was the first to record it from there as <i>M</i>. <i>nicosiana</i> (Fig. 3).</p> <p> Our dissections confirm that the two subspecies of <i>M. nicosiana</i> also have closely related genital anatomies. In both taxa the anatomy shows that the relative lengths of the different parts of the genitalia are similar and the penial papillae are heart-shaped viewed from the upper side, with a central longitudinal groove in the middle. Even more impressive is the fact that animals from the Sanctuary of Apollo Hylates in Cyprus have more similar papillae to the ones from Karpathos than to the animals from Vouni Panagias from Cyprus, which exhibit some additional circular grooves on the surface of the papilla. However, the main shape of the papilla is similar in all of the animals of the two subspecies.</p>Published as part of <i>Bitzilekis, Eleftherios, Vardinoyannis, Katerina & Mylonas, Moisis, 2023, A new species of Metafruticicola (Gastropoda, Hygromiidae) from the Aegean Archipelago and new anatomical and distributional data on some congeneric species, pp. 1-23 in European Journal of Taxonomy 879 (1)</i> on pages 7-10, DOI: 10.5852/ejt.2023.879.2155, <a href="http://zenodo.org/record/8135424">http://zenodo.org/record/8135424</a>
Information theory methods in communication complexity
No full textThis dissertation is concerned with the application of notions and methods from the field of information theory to the field of communication complexity. It consists of two main parts. In the first part of the dissertation, we prove lower bounds on the randomized two-party communication complexity of functions that arise from read-once boolean formulae. A read-once boolean formula is a formula in propositional logic with the property that every variable appears exactly once. Such a formula can be represented by a tree, where the leaves correspond to variables, and the internal nodes are labeled by binary connectives. Under certain assumptions, this representation is unique. Thus, one can define the depth of a formula as the depth of the tree that represents it. The complexity of the evaluation of general read-once formulae has attracted interest mainly in the decision tree model. In the communication complexity model many interesting results deal with specific read-once formulae, such as disjointness and tribes. In this dissertation we use information theory methods to prove lower bounds that hold for any read-once formula. Our lower bounds are of the form n(f )/c^d(f ) , where n(f ) is the number of variables and d(f ) is the depth of the formula, and they are optimal up to the constant in the base of the denominator. In the second part of the dissertation, we explore the applicability of the information-theoretic method in the number-on-the-forehead model. The work of Bar-Yossef, Jayram, Kumar & Sivakumar [BYJKS04] revealed a beautiful connection between Hellinger distance and two-party randomized communication protocols. Inspired by their work and motivated by the open questions in the number-on-the-forehead model, we introduce the notion of Hellinger volume. We show that it lower bounds the information cost of multi-party protocols. We provide a small toolbox that allows one to manipulate several Hellinger volume terms and also to lower bound a Hellinger volume when the distributions involved satisfy certain conditions. In doing so, we prove a new upper bound on the difference between the arithmetic mean and the geometric mean in terms of relative entropy. Finally, we show how to apply the new tools to obtain a lower bound on the informational complexity of the ANDk function.Ph. D.Includes bibliographical referencesby Nikolaos Leonardo
