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
The influence of the NE winter monsoon on productivity changes in the Gulf of Aden, NW Arabian Sea, during the last 530ka as recorded by foraminifera
No full textBenthic and selected planktic foraminifera and stable isotope records were determined in a piston core from the Gulf of Aden, NW Arabian Sea that spans the last 530 ka. The benthic foraminifera were grouped into four principal assemblages using Q-mode Principal Component Analyses. Comparison of each of these assemblages with the fauna of the nearby regions enabled us to identify their specific environmental requirements as a function of variability in food supply and strength of the oxygen minimum zone and by that to use them as indicators of surface water productivity. The benthic foraminiferal productivity indicators coupled with the record of Globigerina bulloides, a planktic foraminifer known to be sensitive to productivity changes in the region, all indicate higher productivity during glacial intervals and productivity similar to present or even reduced during interglacial stages. This trend is opposite to the productivity pattern related to the SW summer monsoon of the Arabian Sea and indicates the role of the NE winter monsoon on the productivity of the Gulf of Aden. A period of exceptionally enhanced productivity is recognized in the Gulf of Aden region between similar to 60 and 13 kyr indicating the intensification of the NE winter monsoon to its maximal activity. Contemporaneous indication of increased productivity in other parts of the Arabian Sea, unexplained so far by the SW summer monsoon variability, might be related to the intensification of the NE winter monsoon. Another prominent event of high productivity, second in its extent to the last glacial productivity event is recognized between 430 and 460 kyr. These two events seem to correspond to periods of similar orbital positioning of rather low precession land eccentricity) amplitude for a relatively long period. Glacial boundary conditions seem to control to a large extent the NE winter monsoon variability as also indicated by the dominance of the 100 ka cycle in the investigated time series. Secondary in their importance are the 23 and 41 ka cycles which seem also to contribute to the NE monsoonal variability. Following the identification of productivity events related to the NE winter monsoon in the Gulf of Aden, it is possible now to extend this observation to other parts of the Arabian Sea and consider the contribution of this monsoonal system to the productivity fluctuations preserved in the sedimentary records.

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.

Farklı Sinterizasyon Yöntemlerinin ve Blok Renginin Monolitik Zirkonya ile Adeziv Rezin Siman Arasındaki Bağ Dayanımına Etkisi
No full textAmaç: Bu çalışmanın amacı; farklı sinterizasyon yöntemlerinin ve blok renginin monolitik zirkonya ile adeziv rezin siman arasındaki makaslama bağ dayanımı üzerindeki etkilerinin incelenmesidir.
Gereç ve Yöntemler: Kendinden renkli (InCoris TZI C A2, Sirona) (CZ) ve renksiz (InCoris TZI, Sirona) (Z) monolitik zirkonya blokları, sinterizasyon sonrası 4mm×4mm×4mm boyutlarında olacak şekilde küpler halinde kesildi (N=40). Renkli ve renksiz örnekler, konvansiyonel sinterizasyon (KS) ve hızlı sinterizasyon (HS) olmak üzere 2 alt gruba ayrıldı (n=10). Akrilik içerisinde sabitlenen örnekler kumlandıktan sonra primer uygulandı. Adeziv rezin siman (çap:2mm, yükseklik:2mm) şekillendirildi ve polimerize edildi. Makaslama bağ dayanım (SBS) testinin (Bisco, ABD, 0.5 mm/dk) uygulanması ile elde edilen verilerin istatistiksel analizi (SPSS 26, 2-yönlü ANOVA, bağımsız t-testi) gerçekleştirildi (p=0.05). Kırık tipleri sınıflandırıldı.
Bulgular: En yüksek SBS değeri KS-Z (25.13±8.47) grubunda, en düşük SBS değeri ise HS-Z (14.89±7.08) grubunda gözlendi. SBS değerleri üzerinde sinterizasyon yöntemlerinin istatistiksel açıdan anlamlı etkisi bulunurken (p=0.006) monolitik zirkonyanın renkli olma özelliğinin anlamlı etkisi görülmedi (p>0.05). Renksiz bloklarda, KS (25.13±8.47) grubunda HS (14.89±7.08) grubuna göre istatistiksel olarak yüksek değerler bulundu (p=0.009). Renkli bloklarda ise HS (17.99±5.21) ve KS (20.89±7.31) grupları arasındaki farkın istatistiksel açıdan anlamlı olmadığı görüldü (p>0.05). Hem hızlı hem de konvansiyonel sinterizasyonda ise Z ve RZ grupları arasında anlamlı bir farklılık bulunmadı (p>0.05).
Sonuç: Farklı sinterizasyon yöntemlerinin, renksiz monolitik zirkonya bloklar ile adeziv siman arasındaki makaslama bağ dayanımını etkilerken renkli monolitik zirkonya bloklar ile adeziv rezin siman arasındaki makaslama bağ dayanımını etkilemediği bulundu. Blokların önceden renklendirilmiş veya renklendirilmemiş olması, monolitik zirkonya ile adeziv siman arasındaki makaslama bağ dayanımını etkilemedi.

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 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.
