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
Co-Designing Smartphone Notifications According to the Clinical Routine of Cancer Patients
No full textAlthough smartphone-based notifications offer a promising tool to support patient engagement and data collection via mobile health apps, attention must be given to the burden caused by frequent notifications and notification timing. This study presents a personalized mobile notification scheme, designed and developed to optimize reachability, and thus data collection from patients. Engineers, psychologists, oncologists, and patients were involved in various stages of a co-design approach and the presented implementation is currently used in the context of a clinical study.Although smartphone-based notifications offer a promising tool to support patient engagement and data collection via mobile health apps, attention must be given to the burden caused by frequent notifications and notification timing.

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
ANALISIS KINERJA SIMPANG TAK BERSINYAL PADA SIMPANG 3 JL. A.A. MARAMIS KOTA MANADO
No full textSimpang tak bersinyal merupakan suatu persimpangan yang terdiri atas beberapa arus jalan yang tidak memiliki lampu lalu lintas. Tujuan dari penelitian ini adalah untuk menganalisis volume lalu lintas, menentukan kinerja simpang berdasarkan perhitungan MKJI 1997, dan menentukan tingkat pelayanan (LOS) pada simpang prioritas tak bersinyal JL. A. A. Maramis.
Dari hasil penelitian yang diperoleh menunjukkan volume lalu lintas total pada Senin = 58015,7 smp/jam, Selasa = 63070,3 smp/jam, Rabu = 56558,4 smp/jam, Kamis = 56075 smp/jam, Jumat = 56961 smp/jam, Sabtu = 41045 smp/jam, Minggu = 37246 smp/jam. Untuk nilai kapasitas (C) pada hari Senin = 4596,13 smp/jam, Selasa = 4342,84 smp/jam, Rabu = 4235,86 smp/jam, Kamis = 4627,87 smp/jam, Jumat = 4515,81 smp/jam, Sabtu = 4333,56 smp/jam, Minggu = 4349,76 smp/jam. Derajat Kejenuhan (DS) didapat pada hari Senin = 1,102, Selasa = 1,203, Rabu = 1,151, Kamis = 1,035, Jumat = 1,138, Sabtu = 0,977, Minggu = 0,926. Hal ini mengindikasikan bahwa simpang prioritas tak bersinyal ini tergolong cukup buruk karena nilai derajat kejenuhan (DS) yang diperoleh lebih dari 0,75. Tundaan Simpang (D) diperoleh pada hari Senin = 25,542 det/smp, Selasa = 41,114 det/smp, Rabu = 31,062 det/smp, Kamis = 20,792 det/smp , Jumat = 29,432 det/smp, Sabtu = 18,019 det/smp, Minggu = 16,178 det/smp. Peluang Antrian (QP%) diperoleh nilai pada hari Senin = 98-49 %, Selasa = 120-59 %, Rabu = 108-54 %, Kamis = 86-43 %, Jumat = 106-53 %, Sabtu = 76-38 %, Minggu = 68-34 %.
Berdasarkan hasil penelitian tingkat pelayanan persimpangan (LOS) simpang tak bersinyal pada simpang 3 JL. A. A. Maramis diperoleh nilai terbesar selama 1 minggu yaitu 41,114 det/smp (40,1 - 60), sehingga termasuk dalam kategori tingkat pelayanan E yaitu memiliki arus lebih tinggi daripada tingkat pelayanan D dengan volume lalu lintas mendekati kapasitas jalan, dan kecepatan sangat rendah, memiliki kepadatan lalu lintas tinggi karena hambatan internal lalu lintas tinggi, pengemudi mulai merasakan kemacetan – kemacetan durasi pendek.
Kata Kunci : Simpang, Kinerja Simpang Tak Bersinyal, Tingkat Pelayanan Jala
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
