Objectives: To evaluate the efficacy and safety of m.c.anical debridement and suturing of the laser in situ keratomileusis (LASIK) flap in the treatment of cl inically significant epithelial ingrowth after LASIK. methods: In a retrospectiv e study, 20 eyes (n=19 patients) in which clinically significant epithelial ingr owth developed after LASIK were treated with lifting of the flap, scraping of th e epithelial ingrowth, and flap suturing. Primary outcome measurements including recurrence of ingrowth, uncorrected visual acuity (VA), manifest refraction, be st spectacle-corrected VA, and complications were evaluated at the last postope rative examination. Results: At the last postoperative examination (mean±SD, 10 .5 ±14.3 months; range, 1.5-64 months), 100%of eyes had no recurrence of clin ically significant epithelial ingrowth. The uncorrected VA changed from 20/20 or better in 7 eyes (35%) and 20/40 or better in 15 eyes (75%) preoperatively to 20/20 or better in 9 eyes (45%) and 20/40 or better in 16 eyes (80%) at the l ast follow-up examination. There was no significant change in the mean logarith m of the minimum angle of resolution (logmAR) uncorrected VA before (mean±SD, 0 .3±0.5; range, -0.1 to 1.7) and after surgery (mean±SD, 0.2±0.4; range, -0. 1 to 1.7) (P=.40). mean±SD spherical equivalent changed from -0.21±0.82 diopt ers (D) (range, -1.25 to 1.00 D) preoperatively to -0.53±0.89D (range, -2.50 to 0.38 D) at last follow-up (P=.30). No eyes lost 2 or more lines of best spe ctacle-corrected VA, and there were no complications as sociated with the treatment. conclusions: Suturing the LASIK flap in addition to m.c.anical debridement of epithelial ingrowth is a safe and effective treatme nt for clinically significant epithelial ingrowth after LASIK.

Background Araucaria araucana is a mast species that presents a high variability in annual cone production. Researchers have recorded synchronization events in cone production in different populations, which allows the seed production to be concentrated, reducing the percentage of seeds consumed by different animal *** We sampled three populations located in the Andes mountains, Araucanía Region, chile. In 2004 we began the collection of data on cone production, for which we installed permanent plots（1200 m2each） at each location. We identified and labeled each female tree in each plot to monitor its cone production. In 2012 we selected a total of 30 trees near the plots to evaluate the number of seeds per cone. In each February from 2012 to 2014 we selected two mature cones and covered them with a porous mesh for subsequent collection and storage in march. At the beginning of June, we counted and weighed the seeds, determining the average weight, the number of seeds per cone, the germination capacity（Gc）, and the germination speed（GS）.Results cone production was synchronous across the three locations. We observed significant differences among the locations and years evaluated. The cones had fewer seeds in 2013（high production） compared to those in 2012（low production）, but their weights were similar. In 2014 the cones produced smaller seeds in fewer quantities. The difference between the years 2013 and 2014 resulted from the high-energy expenditure in 2013. Regarding Gc and GS, there were significant differences among the three locations（Gc: F = 45.41, p c and GS are related to seed weight but not to the number of cones produced in a given year. These annual fluctuations in seed production are determining factors in the population dynam.c. of forest species. Our results allow a better understanding of the reproductive phenology of A. araucana and could hel

Performance of evolutionary optimized m.c.ine learning for modeling total organic carbon in core samples of shale gas fields

Petroleum 2024年第1期10卷 150-164页

作者： Leonardo Goliatt c.m.Saporetti L.c.Oliveira E.Pereira Department of computational and Applied m.c.anics Federal University of Juiz de Fora Department of computational modeling Polytechnic Institute Rio de Janeiro State University Petrobras Department of Stratigraphy and Paleontology Rio de Janeiro State University

Rock samples' TOc content is the best indicator of the organic matter in source rocks. The origin rock samples' analysis is used to calculate it manually by specialists. This method requires time and resources because it relies on samples from many well intervals in source rocks. Therefore, research has been done to aid this effort. m.c.ine learning algorithms can estimate total organic carbon instead of well logs and stratigraphic studies. In light of these efforts, the current work present a study on automating the total organic carbon estimation using m.c.ine learning approaches improved by an evolutionary methodology to give the model flexibility and precision. Genetic algorithms, differential evolution, particle swarm optimization, grey wolf optimization, artificial bee colony, and evolution strategies were used to improve m.c.ine learning models to predict TOc. The six metaheuristics were integrated into four m.c.ine learning methods: extreme learning m.c.ine, elastic net linear model, linear support vector regression, and multivariate adaptive regression splines. core samples from the YuDong-Nan shale gas field, located in the Sichuan basin, were used to evaluate the hybrid strategy. The findings show that combining m.c.ine learning models with an evolutionary algorithms in a hybrid fashion produce flexible models that accurately predict TOc. The results show that, independent of the metaheuristic used to guide the model selection, optimized extreme learning m.c.ines attained the best performance scores according to six metrics. Such hybrid models can be used in exploratory geological research,particularly for unconventional oil and gas resources.

Semi-analytical investigation of heat transfer in a porous convective radiative moving longitudinal fin exposed to magnetic field in the presence of a shape-dependent trihybrid nanofluid

引用

Applied mathematics and m.c.anics(English Edition) 2024年第1期45卷 197-216页

作者： c.G.PAVITHRA B.J.GIREESHA m.L.KEERTHI Department of PG Studies and Research in mathematics Kuvempu UniversityShankaraghatta 577451India Department of mathematics and Statistics M.S.Ramaiah University of Applied SciencesBengaluru 560058India

The thermal examination of a non-integer-ordered mobile fin with a magnetism in the presence of a trihybrid nanofluid(Fe_3O_4-Au-Zn-blood) is carried out. Three types of nanoparticles, each having a different shape, are considered. These shapes include spherical(Fe_3O_4), cylindrical(Au), and platelet(Zn) configurations. The combination approach is utilized to evaluate the physical and thermal characteristics of the trihybrid and hybrid nanofluids, excluding the thermal conductivity and dynam.c.viscosity. These two properties are inferred by means of the interpolation method based on the volume fraction of nanoparticles. The governing equation is transformed into a dimensionless form, and the Adomian decomposition Sumudu transform method(ADSTm) is adopted to solve the conundrum of a moving fin immersed in a trihybrid nanofluid. The obtained results agree well with those numerical simulation results, indicating that this research is reliable. The influence of diverse factors on the thermal overview for varying noninteger values of γ is analyzed and presented in graphical representations. Furthermore, the fluctuations in the heat transfer concerning the pertinent parameters are studied. The results show that the heat flux in the presence of the combination of spherical, cylindrical, and platelet nanoparticles is higher than that in the presence of the combination of only spherical and cylindrical nanoparticles. The temperature at the fin tip increases by 0.705 759% when the value of the Peclet number increases by 400%, while decreases by 11.825 13% when the value of the Hartman number increases by 400%.
