The small, narrow and smooth body distinctly differentiates it from many other Corydiidae genera whose body is pubescent and oval shaped. Roth (1995b) considered this genus most resembles genus <i>Homopteroidea</i>, a detailed generic comparison has been provided in Roth (1995b), we add the following comparison as supplement: 1) body smooth, not pubescent in <i>Ctenoneura</i>, while body smooth, with a few setae in <i>Homopteroidea</i>; 2) tegmen with well-developed M, but simplified CuA in <i>Ctenoneura</i> (Fig. 2), while M simple, CuA developed into presutural vein in <i>Homopteroidea</i>; 3) both tegmina and wings with an intercalary vein between R and M in <i>Ctenoneura</i> (Fig. 2), while without an intercalary vein in <i>Homopteroidea</i>; 4) male genitalia simple, with reduced left phallomere, genital hook absent in <i>Ctenoneura</i> (Fig. 1 D), while male genitalia extremely complex in <i>Homopteroidea</i>.</p> <p> <b>Redescription. Male.</b> Small size, resembles small Ectobiidae cockroaches, body length (without wings) 5.0– 9.7 mm. Body smooth and shining, not pubescent, usually coloration ranging from brownish yellow to dark brown.</p> <p> <b>Head:</b> hidden or not, vertex round, eyes wide apart, ocelli very small, nearly degenerate, antennal sockets round, large. <b>Pronotum:</b> generally subcircular or oval. <b>Tegmina and wings:</b> fully developed. Major veins often densely reticulate with numerous cross veins. Tegmina horny, Sc and branches of R usually oblique, M welldeveloped, usually with 3–6 branches, an intercalary vein present between R and M, sometimes incomplete, CuA usually simple, sometimes bifurcate; wings with a mass of spots between RA and RP, usually with an intercalary vein between R and M, sometimes incomplete, CuA usually with 3 to 8 branches that generally are parallel, and with numerous small cross veins connecting them, CuP usually slender, anal area folded over the rest of the wing in resting position as in other Corydiidae genera, AA thick, AP branches fan-like (Fig. 2). <b>Legs:</b> front femur Type C1, sometimes with small processes on hind margin basally and setae on the surface (Figs. 23 D; 24 D). Pulvilli absent, tarsal claws symmetrical, simple, arolia small or absent. <b>Abdomen:</b> abdominal terga unspecialized. Supra-anal plate transverse, with many different shapes. Cerci long, pubescent, sometimes the basal segments specialized (round or slightly protruded and directed medially, e.g. Fig. 20 E). Subgenital plate asymmetrical, different from one species to another, usually with one stylus or none (Roth (1993) stated some species without stylus). Some species with one slender and curved subgenital sclerite (sgs) present above the subgenital plate, below the genitalia, or integrated with subgenital plate, and an extending structure (eds) to hold the sgs (Fig. 13; 22 F–G).</p> <p> <b>Male genitalia:</b> consists of three parts, viz. left phallomere, right phallomere and transverse sclerite (tvs). Left phallomere strongly reduced, two parts present, viz. left dorsal phallomere (ldp) and left ventral phallomere (lvp); lvp small, usually with irregular processes posteriorly, anterior usually acute, like a parrot peak; ldp connects lvp by the whole anterior margin, posterior with a <b>curved part</b> (<b>cvp</b>), small, towards the anterior. Right phallomere consists of three parts, viz. R1M, R2 and R3, R1M irregular, R2 with three parts: a robust process (rop), a slender process (slp) and an elongate process (elp), R3 concave. Transverse sclerite (tvs) long, irregular (Fig. 1).</p> <p> <b>Female.</b> Apterous, body smooth, eyes reduced, arolia absent, supra-anal plate transverse, suboval, apex slightly truncated, cerci robust, apex with a spine. Subgenital plate valvular (Figs. 5 G–J).</p> <p> <b>Ootheca.</b> Oval, with small serrations on the keel. The surface with many ribbed lines, eggs filled, can be seen in dorsal view (Figs. 5 K–L).</p> <p> <b>Distribution.</b> Oriental Region.</p> <p> <b>Natural history.</b> <i>Ctenoneura</i> should be one kind of wood-feeding cockroach. For more details see “natural history” under <i>C. heixuanfeng</i> and <i>C. delicata</i>.</p> <p> <b>Discussion. The estimate of species abundance.</b> <i>Ctenoneura</i> must be a genus rich in species in the Corydiidae. Members of this rarely-collected genus are mostly recorded from Southeast Asia. Former studies only found four species from China (Bey-Bienko 1957, 1969), one species from Myanmar and one undescribed species from Vietnam (Roth 1993).This paper adds three species from Yunnan, four species from Hainan Island and one unknown female from Guangxi. We suspect that there must be more new species in China, Myanmar and Vietnam.</p> <p> <b>Species groups suggestion.</b> After dissecting the specimens, we found <i>C. simulans</i>, <i>C. helicata</i> <b>sp. nov.</b> and <i>C. qiuae</i> <b>sp. nov.</b> share some similar characters: 1) supra-anal plate simple, unspecialized; 2) subgenital plate with eds forming a groove, and separated sgs partly resting in the groove; 3) hind margin of subgenital plate usually with an incision or excavation, one stylus originating from the left of the incision or excavation. Here we build a <b> <i>simulans</i> - group</b> to contain <i>C. simulans</i> Bey-Bienko, 1969, <i>C. helicata</i> <b>sp. nov.</b> and <i>C. qiuae</i> <b>sp. nov.</b> that all own the characters listed above. <i>C. elongata</i> <b>sp. nov.</b> is different from the typical <i>simulans</i> -group, it is distinct in owning an unseparated sgs and an extremely large eds; we include it in this group as an “aberrant” species. <i>C. birmanica</i> Princis, <i>C. misera</i> Bey-Bienko and <i>C. yunnanea</i> Bey-Bienko may belong to this group, but we lacked material to examine. The species from Hainan Island are quite distinguished from each other in the supra-anal plate and subgenital plate, but they all share some other identical characters: 1) supra-anal plate all specialized into different shapes; 2) subgenital plate protrudes toward right; and 3) body dark brown to brownish black, usually with small yellow areas in lateral fore borders of the pronotum. We suggest building a <b> <i>heixuanfeng</i> -group</b> for the Hainan species described in this article.</p> <p> <b>Discussion of females.</b> The apterous female reported in this article is one important discovery on <i>Ctenoneura.</i> The previous records of the females (Hanitsch 1925; Bey-Bienko 1957) indicates macropterous, but they are doubtful. Hanitsch (1925) described <i>C. fulva</i> based on six specimens, and <i>C. major</i> based on two specimens; within these were three macropterous females determined by Hanitsch himself. But there were two significant concerns about Hanitsch’s knowledge of <i>Ctenoneura.</i> One is the generic diagnosis of this genus having the male with two styli which later proved to have the male with one stylus or none. The other concern is about the type series of <i>C.</i></p> <p> <i>fulva.</i> Roth (1993) has examined the type specimens of <i>C. fulva</i> in the Museum of Oxford University. No females were found, but he discovered two new species within the type series of <i>C. fulva</i> (one was described as <i>C. murudensis</i>, the other was not described due to its bad condition). Such limited knowledge may lead to mistaken identification. At that time, the male subgenital plate of <i>Ctenoneura</i> was poorly studied. Hanitsch probably mixed in other male species as the females of <i>C. fulva</i> and <i>C. major</i>. Bey-Bienko (1957) described <i>C. acuticerca</i> based on two macropterous females, but this species may not belong to <i>Ctenoneura</i> due to the absence of an intercalary vein which is an important character for <i>Ctenoneura</i>. The discovery of the apteral female in this article may explain why the previous studies are absence of females; the sexual dimorphism may lead to overlooking the females.</p> <p> <b>Taxonomic status.</b> So far the subfamily status of <i>Ctenoneura</i> is still unclear. Princis (1950, 1953, 1963, 1967) put this genus in Latindiinae / Latindiidae without giving any reasons, Roth (1993, 1995b, 2003) and Beccaloni (2014) did not place it in any subfamily. The many distinctive characters (the much reduced left phallomere, the absence of genital hook, specialized and asymmetrical subgenital plate, single stylus, smooth body, intercalary vein presenting in tegmina and wings, well developed M and simplified CuA in tegmen) make it unique in the Corydiidae. It may belong to a new subfamily named Ctenoneuriinae. However, more <i>Ctenoneura</i> examples need to studied, more comparison studies within Corydioidea genera need to be done, and molecular methods need to be used to solve this problem.</p>Published as part of <i>Qiu, Lu, Che, Yan-Li & Wang, Zong-Qing, 2017, Contribution to the cockroach genus Ctenoneura Hanitsch, 1925 (Blattodea: Corydioidea: Corydiidae) with descriptions of seven new species from China, pp. 265-299 in Zootaxa 4237 (2)</i> on pages 268-271, DOI: 10.11646/zootaxa.4237.2.3, <a href="http://zenodo.org/record/343796">http://zenodo.org/record/343796</a>

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
L-invariants for cohomological representations of PGL(2) over arbitrary number fields
No full textGehrmann L, Pati MR. L-invariants for cohomological representations of PGL(2) over arbitrary number fields. Forum of Mathematics, Sigma. 2024;12: e71.**Abstract**
Let
be a cuspidal, cohomological automorphic representation of an inner form
G
of
over a number field
F
of arbitrary signature. Further, let
be a prime of
F
such that
G
is split at
and the local component
of
at
is the Steinberg representation. Assuming that the representation is noncritical at
, we construct automorphic
-invariants for the representation
. If the number field
F
is totally real, we show that these automorphic
-invariants agree with the Fontaine–Mazur
-invariant of the associated
p
-adic Galois representation. This generalizes a recent result of Spieß respectively Rosso and the first named author from the case of parallel weight
to arbitrary cohomological weights.

масового обслуговування типу GI /G/ c/ 0 / L / /G від часу. Зобр.: 2. Бібліогр.: 13 назв.The article adresses research on retrial queueing systems. Queueing systems constitute a central tool in modelling and performance analysis of e.g. telecommunication systems and computer systems. Often the systems are complex (for instance, communication network, operating system) and contains many queues, which form a network of queues, i.e. a queueing network. The author considers a multichannel retrial queuing system GI / G/ С/ 0 / L / /G (with С channels, generilised input flow, general service times, general orbit's sojourn times, and orbit of capacity of L) in the article. Distribution functions of intervals between moments of calls' arrival, service and sojourn times of retrials are of general form. Such systems as GI / G/ С/0 / L/ /G can be represented as a set of Kolmogorov equations (an analytical model). It is very hard and sometimes impossible to obtain explicit formulas when trying to solve such set of equations, especially when it comes to generil distribution times. That is why an gorithm of statistical modeling of GI / G / С/ 0 / L //G system is introduced in order to estimate stationary average number of demands in the system. Graphical results are given
Investigating Reddit to detect subreddit and author stereotypes and to evaluate author assortativity
No full textIn recent years, Reddit has attracted the interest of many researchers due to its popularity all over the world. In this article, we aim at providing a contribution to the knowledge of this social network by investigating three of its aspects, interesting from the scientific viewpoint, and, at the same time, by analysing a large number of applications. In particular, we first propose a definition and an analysis of several stereotypes of both subreddits and authors. This analysis is coupled with the definition of three possible orthogonal taxonomies that help us to classify stereotypes in an appropriate way. Then, we investigate the possible existence of author assortativity in this social medium; specifically, we focus on co-posters, that is, authors who submitted posts on the same subreddit
