Etymology. The species epithet indicates the distinct broad yellow rings in abdominal segments S3–S7. Description of holotype. Head. Face shining black marked with bright yellow. Vertex black with a pale greenish yellow ridge between the eyes; occiput black; median ocellus transparent and lateral ocellus coffee brown in colour. Postfrons with transverse broad yellow stripe; antefrons shining black; antennae black with yellow basal segment; postclypeus with dumbbell–shaped bright yellow band with narrow central part and broad outwardly rounded region; yellow band extends down to the lower half of the eyes. Basal half of labium and mandibles bright yellow and shining black distally. Labrum bright yellow with an inverted broad black triangular mark. Eyes dark green above and light green below which turns into brown upon dry preservation (Figs. 2 & 3). Thorax. Prothorax: Anterior lobe yellow, middle and posterior lobe black, with a short yellow stripe in propleuron. Pterothorax: Shining black marked with bright yellow stripes; mesothoracic collar short and yellow; antealar sinus with anteriorly pointed dagger–shaped yellow mark; three broad yellow spots present in–between the wings with the middle one being the broadest. Mesepimeron with broad yellow stripe pointed above; a small superior yellow humeral spot present; metepisternum and metepimeron with broad yellow bands separated by shining black band with a small yellow spot towards the dorsal side (Fig. 4). Legs black, the yellow stripes on the mesepimeron and metepimeron extend to the coxa of the hind and midleg. Foreleg has a yellow spot on the femur, hind leg short with femur extending up to the first abdominal segment when extended (Fig. 4). Wings. Transparent, pterostigma braced, light brownish black covering three cells; a single row of post–anal cells in forewing and four in hind wing; anal loop absent; hind wing angulated; anal triangle 3–celled; one cubital nervure in all wings; discoidal cell and sub–trigone entire; discoidal cell with distal side longest, nearly double the length of basal side in hind wing; forewing discoidal cell an approximate equilateral; two rows of cells between MA and MP; two rows of cells between RP 2 and IRP 2 in wing border of fore– and hind wing; one row of cells between CuA and MP; a basal incomplete nervure in all wings; sectors of Arc diverging from the Arc, 2–3 nervures in forewing and two in hind wing between Arc and bifurcation of Rs; nodal index 9–13/13–8; 8–10/10–8 (Fig. 1). Abdomen. Abdomen black marked with bright yellow as follows; S1 yellow laterally; S2 with yellow dorsal and lateral markings; S3 with thin backwardly tapering dorsal yellow line extending to more than two–thirds of the segment length; S3–S6 cylindrical; S3–S7 each with a broad basal yellow ring constricted mid–dorsally on S3–S6, expanded ventro–laterally on S7–S9; S8–S9 with narrow basal ring with broad lateral marking extending to half or more than half of the segments. S10 with broad basal yellow ring (Fig. 1). Accessory genitalia. Lobe of genitalia enormously enlarged, black, posterior hamules very long and projecting prominently from the genital sac, with its apices pointed and turned outwards (Fig. 7). Anal appendages. Completely black, epiprocts longer than cerci. Cerci scalpel–shaped, bent downwards as seen in lateral view, with a backward and downward pointing spine, divergent from half way down the length. Epiprocts widely divaricate, almost pointing in opposite directions; tip curled inwards and downwards, a small bulging projection just distal to its middle down the length (Figs. 5, 6, 8, 9 & 12). The curled tip of epiprocts in the holotype is due to drying of the specimen. In live specimens photographed from field (20, 27b) the tips of epiprocts are straight. Measurements (in mm). Hindwing 25, abdomen 29. Allotype female. Similar to the male (Figs. 22–25). Paratype male. Similar to the holotype (Figs.17–21). Measurements (in mm). Allotype female: Hindwing 26.5, abdomen 31. Paratype male: Hindwing 24, abdomen 29. Differential diagnosis. Cyclogomphus flavoannulatus can be distinguished by the absence of black Y–shaped lateral thoracic markings and the markings on the abdomen in both male and female. In contrast, C. gynostylus (Figs. 31 & 32) and C. heterostylus each have two black Y–shaped lateral thoracic markings whereas C. wilkinsi (Fig. 29) and C. ypsilon (Fig. 30) each have one black Y–shaped lateral thoracic marking. Abdominal segments S3–S7 of C. flavoannulatus each have only a distinct basal yellow ring while S3–S7 additionally has a yellow mid–dorsal stripe in C. wilkinsi and a yellow oval spot in C. ypsilon. The abdominal marking of C. heterostylus is similar to that of C. ypsilon and in C. gynostylus the S4-S6 has complete narrow basal rings and laterally expanded broad yellow ring in S7 (Figs. 31–32). The new species also differs from its congeners by the unique shape of the anal appendages (Figs. 5, 6, 8–16). The caudal appendages of C. ypsilon (not illustrated) is similar to that of C. wilkinsi (Figs. 10 & 14) but branches of epiprocts shorter with yellow base and black outer half. Habitat and Ecology. The holotype and female paratype from Goa were collected from a moist–deciduous forest with two perennial streams with riparian evergreen trees. Other gomphid species observed in the locality were Merogomphus longistigma (Fraser, 1922), Microgomphus souteri Fraser, 1924 and Gomphidia koduguensis Fraser, 1923. The paratype male from Kerala was recorded from a garden pond in a homestead, where a male was found perched on bank vegetation at a height of 1.5 m from the ground. The flight was rather slow and ill–sustained, and when disturbed they took to the wing but settled down on the undergrowth few meters further away. The flight period is September–October. Geographic Distribution. The species is recorded from the Western Ghats between 8–15°N in the states of Goa and Kerala (Map–01).Published as part of Rangnekar, Parag, Dharwadkar, Omkar, Sadasivan, Kalesh & Subramanian, K.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.

Asthma and youth soccer: an investigation into the level of asthma awareness and training among youth soccer coaches
No full textChandu Sadasivan, Andrew Cave Department of Family Medicine, University of Alberta, Edmonton, AB, Canada Purpose: Asthma is the most common chronic disease among children. Exercise-induced bronchoconstriction which is common in asthmatic patients also occurs in individuals with no prior asthma diagnosis. Despite this and the fact that soccer is a high ventilation sport, there are no validated asthma management protocols in place for soccer coaches. This study aims to address 1) soccer coaches’ current knowledge on asthma, 2) whether there is a need for asthma-related training, and 3) any barriers to administration of such training.Patients and methods: A total of 2,300 volunteer youth soccer coaches from the Edmonton Minor Soccer Association (EMSA) were invited to participate in completing a 22-question online survey. The survey was open for 1 month from June 8, 2018, to July 8, 2018.Results: There was a response rate of 22% (513 of 2,300). Respondents were on average, inexperienced coaches, coached younger age groups, and approximately one-third of respondents had personal experience with asthma (either themselves or their child had asthma). 93% of respondents had not received any asthma-related training at any coaching level, whether it be from EMSA or the Alberta Soccer Association. Coaches had strong knowledge on how to treat asthma attacks, but mixed levels of knowledge on asthma attack prevention. Experienced coaches were better at identifying the number of players with asthma on their team and the number of asthma-related incidents they had encountered as coaches. Coaches demonstrated a receptive attitude toward receiving asthma-related training, with 91% of respondents saying training would be beneficial and 69% of respondents saying training should be mandatory.Conclusion: The results of this study indicate that soccer coaches have limited knowledge regarding asthma management, acknowledge a need for asthma-related training, and are willing to participate in and could benefit from educational interventions as it pertains to their roles as coaches.

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
A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
A 0.12mm<sup>2</sup> Wien-Bridge Temperature Sensor with 0.1°C (3σ) Inaccuracy from -40°C to 180°C
No full text Resistor-based temperature sensors can achieve much higher resolution and energy efficiency than conventional BJT-based sensors [1], but they typically occupy more area (> 0.25 mm 2 ) and have lower operating temperatures (le 125 {circ} {C}) [2]-[4]. This work describes a 0.12mm 2 resistor-based sensor that uses a Wien-bridge (WB) filter to achieve 0.1 {circ} {C} (3 sigma) inaccuracy from - 40 {circ} {C} to 180 {circ} {C}. Compared to a state-of-the-art WB sensor [4], it occupies 6 × less area and achieves comparable relative accuracy over a 76% wider operating range.

A ±25A Versatile Shunt-Based Current Sensor with 10kHz Bandwidth and ±0.25% Gain Error from -40°C to 85°C Using 2-Current Calibration
No full textAccurate current sensing is critical in many industrial applications, such as battery management and motor control. Precise shunt-based current sensors have been reported with gain errors of less than 1% over the industrial temperature range (-40°C to 85°C) [1]–[4]. However, since they are intended for coulomb counting, their bandwidth is limited to a few tens of Hz, making them unsuitable for battery impedance or motor-current sensing. This paper presents a current sensor with a wide (10kHz) bandwidth and a tunable temperature compensation scheme (TCS), which allows it to be flexibly used with different types of shunts while maintaining high accuracy. A low-cost room-temperature calibration scheme is proposed to optimize gain flatness over temperature by exploiting the shunt's self-heating at large currents. Over the industrial temperature range and a ±25A current range, it achieves state-of-the-art gain error (±0.25%) with both low-cost PCB and stable metal-alloy shunts.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Electronic InstrumentationMicroelectronic
