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.

Fables Mongo
No full textI have for a long time avoided this huge 671-page book. It combines three languages in offering and commenting upon the fables of the Mongo people in the Democratic Republic of Congo. At least that is what I think it does! If there were a competition among the 6700 books of this collection for the most recherché or academic or unexpected, this book would be in the running. After just a few pages of introductory material (in Flemish?), there are three major sections, as the T of C on 671 shows: Various Animals, The Turtle Cycle, and The Antelope Cycle. A bilingual T of C for the first part (308-13) lists some 125 fables. As will happen in the other two sections, that T of C is preceded by alphabetical lists of the animals involved in these fables. Juding from that T of C, I found no fables that seemed to have been imported from the usual fables, say, of La Fontaine. I tried one: #68: The Eagle and the Monkey. King Elephant once ordered all the animals to form two groups, up above and down below. The eagle urged the monkey to join the up above group, but he refused. Some time later, the eagle found the monkey eating the fruit in a tall tree, challenged him for eating the food of the up above animals, and -- receiving no answer -- killed him. Good fable! The T of C for the second part on 562-64 lists 63 fables. The same sort of check here discovered #44, The Tortoise and the Two Ducks, familiar from Kalila and Dimna. I notice a footnote that this fable is unusual because it presents the tortoise as stupid. People on the ground say Come, look at the king of tortoises! The tortoise opens his mouth to say Yes, I am the king of tortoises! The Antelope Cycle contains 24 fables; their T of C is on 668-69. I am very lucky to have come across this unusual book!Language note: Bilingual: French/MongoR.P. G. Hulstaert, M.S.C
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
04. Mongo Give Good E-Mail
No full textThe first time I met Richard C. Richards (whom I later learned was also known as Mongo) we were at the 2013 LPS conference on the west coast of Florida. He was wearing a T-shirt that said something about having attended his own funeral, so I figured that he, like me, had a penchant for gallows humor. Later, during an author-meets-critics session focusing on his at-the-time-new book (A Philosopher Looks at The Sense of Humor), I was as eager to learn more about his work as I was delighted by the friendly banter between him and the other attendees. Although this was the first time I had been to this conference or met members of the society, it was immediately clear that this was a man who was both loved and respected. So, because I was determined to get a piece of him myself, I bought his book, read it, then reached out to him via email. Thus began one of my most cherished online relationships. Actually, that’s an easy hurdle to clear as I don’t, as a rule, have online relationships and consider the term itself a bit oxymoronic. No, we didn’t become “FaceSpace” friends or start “sexting” one another—in fact, I suspect that he would be as uninterested as I am in such 21st century distractions. Of course, I can only speak for myself, but I hope it will suffice to say that I avoid social media as much as I do angry fire ants or artisanal pizza, and not necessarily in that order. [excerpt
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
