No full textPatula lucetta Hutton, 1884 Pl. 3, fig. E Hutton, 1884. Transactions of the New Zealand Institute, 16 (1883): 162. Type material. Lectotype (designated here), CMNZ M217.2, and paralectotypes (6), CMNZ M217 (dry shells). Label details. CMNZ M217: ‘88. Patula lucetta Hutton, Hawkes Bay’, pillbox label in Hutton’s handwriting. Type locality. ‘ Hawke’s Bay (W. Colenso)’ (Hutton 1884b: 163). Previous illustrations of type material. Hutton (1884b; pl. 11, fig. A—radula). Remarks. Patula lucetta Hutton, 1884 is a subjective synonym of Helix (Patula) stokesi Smith, 1884, which was described from material collected in Wairarapa, North Island (e.g., Hedley & Suter 1893: 654; Suter, 1894b: 268, 1913: 668; Cumber, 1961: 186; Powell, 1979: 323; Brook &Ablett 2019: 58). Hutton’s and Smith’s descriptions were published in May 1884 (see title page of the Transactions and Proceedings of the New Zealand Institute issue for 1883), and October 1884 (see Duncan 1937: 74), respectively, so Patula lucetta Hutton,1884 has priority, as noted by Powell (1979: 323). The type material of this species was listed as being in Canterbury Museum, Christchurch, by Hutton (1898 – 1900: 9), and reported as missing by Freeman et al. (1997: 36) but has since been found. It comprises a mixed assemblage, containing five specimens of P. lucetta one of which (lectotype) is illustrated for the first time in pl. 3, fig. E, and two of Charopa coma (Gray, 1843). This is consistent with the observation by Murdoch (1899: 323), that Hutton’s original account of P. lucetta described the shell and animal coloration of his new species, and a radula of C. coma. Patula lucetta has been listed in genus Phenacohelix Suter, 1892 (e.g., Suter 1913: 668; Powell 1979: 323; Goulstone 2001: 57; Spencer et al. 2009: 216), in Phenacohelix (Neophenacohelix) Cumber, 1961 by Cumber (1961: 186), and in genus Neophenacohelix Cumber, 1961 by Marshall & Worthy (2017: 305), but preliminary results of a phylogenetic study (M. Kennedy & T. King unpub. data) indicate that it belongs in genus Phacussa Hutton, 1883. Patula lucetta has been recorded from both the North and South islands (e.g., Hedley & Suter 1893: 654; Suter 1894b: 269, 1913: 669; Powell 1979: 323; Goulstone 2001: 59, fig. 12). However, Cumber (1961: 186) noted that there are morphological differences between populations on either side of Cook Strait and referred to the taxon as a species complex. The phylogenetic study referred to above found that COI sequences in populations from the North and South islands differed substantially (M. Kennedy & T. King unpub. data), indicating that they should be treated as separate species.Accordingly, Hutton’s name is used here for North Island populations only (below), and northern South Island populations that were previously referred to as lucetta are treated here as an unnamed sister species of lucetta, with a distribution from Marlborough Sounds to Nelson Lakes (AIM and NMNZ collection records). Records of lucetta from ‘Greymouth (R. Helms)’ by Hedley & Suter (1893: 654), Suter (1894b: 269, 1913: 669) and Cumber (1961: 188) were based on mislocalised material (i.e., NMNZ M.275314). Taxonomy. Treated here as Phacussa lucetta (Hutton, 1884) n. comb. Distribution. New Zealand; southern North Island, from Wellington and Wairarapa north to Mt. Taranaki, Lake Taupo and Urewera (Suter 1913: 669 —as Phenacohelix stokesi in part; Cumber 1961: 188 —as P. stokesi in part; Powell 1979: 323 in part; Goulstone 2001: 59, fig. 12 in part; AIM and NMNZ collection records).Published as part of Brook, Fred J., Kennedy, Martyn, King, Tania M., Ridden, Johnathon, Shaw, Matthew D. & Spencer, Hamish G., 2020, Catalogue of New Zealand land, freshwater and estuarine molluscan taxa named by Frederick Wollaston Hutton between 1879 and 1904, pp. 1-73 in Zootaxa 4865 (1) on page 30, DOI: 10.11646/zootaxa.4865.1.1, http://zenodo.org/record/442842

Di nuovo sul principio 'servus fugitivus sui furtum facit'
No full textDa un passo di Africano, D. 47.2.61(60) nonché da un rescritto di Diocleziano in C. 6.1.1 emerge
che il servo, fuggendo, ruba se stesso. Un noto saggio di Fritz Pringsheim ha però negato la
genuinità delle due attestazioni: il principio servus fugitivus sui furtum facit sarebbe emerso in
epoca avanzata, plasmato dalle scuole orientali di diritto. Negli studi successivi, al di là di qualche
rapido accenno, il tema è rimasto piuttosto in ombra. Il presente contributo si propone dunque di
rivisitarlo, discutendo anzitutto la plausibilità dell’ipotesi ricostruttiva di Pringsheim ed
evidenziando i dati che, all’opposto, sembrerebbero ricondurre le origini del principio in discorso
all’epoca classica. Un ruolo centrale avrebbe assunto la scuola sabiniana. Gli esponenti di questa
scuola, particolarmente inclini a scongiurare gli effetti deleteri della fuga, avevano anzitutto
escluso che il padrone perdesse il possesso del servo fuggiasco, per lo meno fino al subentrare di
un nuovo possessore. Per evitare poi che il servo, giunto nelle mani di un bonae fidei possessor,
venisse addirittura usucapito, si sarebbe equiparata la fuga al furto di sé: in tal modo il fugitivus,
qualificabile come res furtiva, sarebbe divenuto inusucapibile
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.

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
