Predictive factors for the efficacy of Er:YAG laser treatment of urinary incontinence
No full textObjectives: To determine the efficacy and predictive factors for the success of Er:YAG laser treatment in patients with urinary incontinence (UI). Methods: Eighty-two patients with UI were treated by Er:YAG laser in this cohort study. The patients were evaluated by ICIQ-SF and KHQ-UI before and after the procedure. Improvement was categorized as: none (0-25%), mild (26-50%), moderate (51-75%), or high (76-100%). The duration of the treatment effect was evaluated at follow-up in relation to maximum improvement time (MIT) and total improvement time (TIT). Results: Forty-two patients were determined to have SUI and 40 patients MUI. The mean ISIQ-SF and KHQ-UI scores significantly improved after the procedure (p < 0.0001). The SUI patients responded to the laser treatment significantly better (p < 0.008). Younger women had significantly better results (p < 0.008), while premenopausal women (p < 0.032) and women in the early postmenopausal years (p < 0.032) also saw a positive response to the Er:YAG laser treatment. Women with a lower BMI had greater improvement (p < 0.011). The total laser energy expenditure during the sessions may also be a predictive parameter for the success of Er:YAG laser treatment of UI (p = 0.059). MIT and TIT were significantly longer among the patients in the high-improvement group. Conclusion: Er:YAG laser treatment of the symptoms of UI, especially SUI, is more efficacious and of longer duration for younger, premenopausal or early postmenopausal women with normal BMI
Determining the size of lightning-induced electron precipitation patches
No full text[1] We analyze Trimpi signatures during 23 and 24 April 1994 at four sites on or near the Antarctic Peninsula (Palmer, Faraday, Rothera, and Halley) on subionospheric VLF signals received from four U. S. naval transmitters (NAA, NSS, NLK, and NPM). Electron precipitation patches are found to be large, i.e., similar to1500 km x 600 km, with the longer axis orientated east-west. Calculations using a three-dimensional Born scattering model, where patch densities are 1.5 electrons cm(-3) above ambient at the center at similar to84 km altitude, provides results that are consistent with this picture. A high proportion (38%) of the Trimpi events were associated with strong lightning flashes in eastern United States. When lightning discharges had currents >65 kA (positive or negative), there was a >80% chance of seeing an associated Trimpi event. The chance of seeing any Trimpi events fell to near zero for discharges of <45 kA. The largest Trimpi perturbations occur when the center of the precipitation patch is 700-800 km from the receivers. This result is consistent with the modeling calculations for large patches. The equatorward edge of the precipitation patch was estimated to be at &SIM;60&DEG;S, close to the magnetic conjugate of the lightning. The close association of the equatorward edge of the precipitation patch with the conjugate location of the causative lightning is consistent with a quasi-ducted whistler-induced precipitation mechanism. Nonducted whistler-induced precipitation mechanisms would predict a 5&DEG;-10&DEG; latitudinal gap between the lightning and the equatorward edge of the patch. However, the lack of observed whistlers at the time of the Trimpi events is consistent with the nonducted whistler mechanism and is not consistent with the quasi-ducted mechanism, although the distances from duct exit point to receiver may have been too large (&SIM;700-1000 km) for the signals to be detectable. Using the significantly larger patch dimensions determined in this study, it is estimated that lightning may well be 10-100 times more effective at depleting the radiation belts than hiss
The Origins of Reinforced Concrete Interventions to Historic Structures in Turkey
No full textReinforced concrete interventions have been a critical issue for restorations in the field of conservation
since the early twentieth century. Until the twenty-first century, cement-containing
interventions could be seen in almost all restorations in Turkey. There are even examples of
monumental buildings whose structural systems have been converted to reinforced concrete.
However, in more recent years in Turkey, reconstructions with echoes of stylistic unity began to
emerge, with less of a focus on preservation and without consideration of the documentary value
of the reinforced concrete used in the strengthening interventions of the twentieth century. From
a structural viewpoint, it is necessary to assess whether mixed structures of reinforced concrete and
masonry work well. From a conservation viewpoint, despite negative perceptions of reinforced
concrete, these historic interventions have avoided confusion or falsification where the precise
original nature of the structure is unknown. With these remarks in mind, this study describes the
origins of reinforced concrete interventions in conservation in Turkey. It provides a general framework
of the concept of interventions for strengthening and preservation at the intersection of
reinforced concrete, earthquakes, codes, and conservation theories by tracking experiences with
reinforced concrete from the Ottoman Empire to the early years of the Republic of Turkey

Er:YAG laser treatment of urinary incontinence after failed TOT/TVT procedures
No full textObjective: To determine if the Er:YAG laser can improve the symptoms of SUI patients after previously failed TOT/TVT procedures. Study Design: This retrospective study includes the data of patients who were recruited from two different out-patient clinics of Obstetrics and Gynecology Department. 25 women with persistent SUI after failed TOT/TVT operations and 25 women who previously did not receive either any type of surgical treatment procedure or non-invasive treatment modalities for SUI. Er:YAG laser with 2940 nm was used in the treatment procedure for SUI setting. The patients were evaluated on the basis of ICIQ-SF before and after the procedure. The severity of SUI symptoms was graded. According to the differences in the ICIQ-SF between before and after the procedure, the percentage of improvement was graded as good responders (>= 50 %) or poor responders (<50 %). The duration of the treatment effect was evaluated in follow-ups with relation to maximum improvement time (MIT) and total improvement time (TIT). Results: The SUI patients who previously had failed TOT/TVT operations, had significantly higher initial ICIQ-SF score (p = 0.013). Non-ablative Er:YAG laser treatment significantly and similarly improved the severity of SUI symptoms in both groups (p = 0.000 for failed TOT/TVT group and p = 0.001 for non-TOT/TVT group, respectively). The women who were good responders, were younger (p = 0.012) and had less number of years in menopause (p = 0.011). The effect of Er:YAG laser treatment lasted longer among the SUI women in the good responders group (p = 0.000 for MIT and p = 0.000 for TIT, respectively). Conclusions: Non-ablative Er:YAG smooth mode laser is an alternative choice of treatment for the SUI patients who previously had failed TOT/TVT procedures. Its effect lasts longer especially in younger and early postmenopausal women. (C) 2020 Elsevier B.V. All rights reserved
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
