Modeling Syntactic Change under Contact: The Case of Italiot Greek
No full textIn this paper, we investigate patterns of persistence and change affecting the syntax of nominal structures in Italiot Greek in comparison to Modern (and Ancient) Greek, and we explore the role of Southern Italo-Romance as a potential source of interference. Our aim is to highlight the dynamics that favor syntactic contact in this domain: we provide an overview of the social context where these dynamics have taken place and of the linguistic structures involved

Whitman and Nietzsche: A Comparative Study of Their Thought
No full textThis volume will be a great aid to students and scholars alike in American literature, American thought, the history of ideas, and comparative literature. Stavrou draws from the entire bodies of work by Whitman and Nietzsche to explore the parallels in the authors' conceptions of paradox, the totality of life, and solitude among other themes in this exploration of the underlying philosophical similarities of these two great writers of the nineteenth century
Pilgrimage, Connection, Community: In Honor of Theofanis G. Stavrou
No full textI first presented these comments at the 44th Annual Convention of the Association for Slavic, East European, and Eurasian Studies (New Orleans, November 2012), as part of a roundtable discussion that honored Theofanis G. Stavrou’s fifty years of service to Mediterranean, Slavic, and Eastern Orthodox Studies. With a few alterations and updates, these words stand as an appropriate conclusion to this volume of essays exploring the main topical interests—Eastern Orthodox Church history, Modern Greek literature, Russian history and culture, the history of Cyprus, and several other areas—in the truly outstanding scholarly career of Theo Stavrou
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.

Digital twin-enabled multi-step strategies for autonomous power equalization in optical networks
No full textThis paper proposes and experimentally evaluates digital twin techniques, incorporating multi-step lookahead and dynamic step-size adjustments for per-channel power equalization in optical networks. Digital twins, which are software replicas of physical systems, are utilized to monitor, analyze, and predict the network behavior, thereby enhancing decision-making processes before implementing any physical adjustments. The study focuses on optimizing the signal-to-noise ratio (SNR) through per-channel launch power equalization, addressing challenges, such as nonlinear inter-channel interference and power transfers across multiple optical multiplex sections. The proposed methodology leverages a digital twin to simulate and predict SNR variations using multi-step lookahead, ensuring the monotonous SNR improvement without service disruptions. Additionally, parallel adjustment and dynamic step-size methods significantly enhance efficiency. Experimental validation on a C-band meshed optical network testbed demonstrates substantial reductions in power errors, improved SNR performance, and decreased commissioning time, highlighting the practical feasibility and efficiency of the approach. The findings underscore the transformative potential of digital twins in advancing autonomous optical network management
