Let L =-△+V(x) be a Schrodinger operator, where △ is the Laplacian on R^n,while nonnegative potential V(x) belonging to the reverse Holder class. The aim of this paper is to give generalized weighted Morrey estimates for the boundedness of Marcinkiewicz integrals with rough kernel associated with Schrodinger operator and their ***, the boundedness of the commutator operators formed by BMO functions and Marcinkiewicz integrals with rough kernel associated with Schrodinger operators is discussed on the generalized weighted Morrey spaces. As its special cases, the corresponding results of Marcinkiewicz integrals with rough kernel associated with Schrodinger operator and their commutators have been deduced, respectively. Also, Marcinkiewicz integral operators, rough Hardy-Littlewood(H-L for short) maximal operators, Bochner-Riesz means and parametric Marcinkiewicz integral operators which satisfy the conditions of our main results can be considered as some examples.

The aim of this study was to uncover all aspects and extract comprehensive and valuable information from thedata obtained from different pepper varieties using machine learning (ML) methods. The red pepper (RP),fabricated isot (FI), and customary isot (CI) spices were stored for 12 months and the variations in the organiccompound content were monitored every 3 months. The data set has been subjected to a supervised ML methodRandom Forest (RF), unsupervised ML methods principal component analysis (PCA), t-Distributed stochasticneighbor embedding (t-SNE), and hierarchical cluster analysis (HCA). The classification accuracy yielded by theRF model was 100%. RF model showed that terpenoids, acids, and alkanes were ineffective in identifying thedifferences between pepper spices, but glucose, succinic acid, citric acid, and fructose were primarily responsiblefor the variations between pepper spices. FI peppers differed significantly from other pepper spices in terms oftheir chemical compositions. Although most organic compounds exhibited positive correlations;furan-fructose,furan-glucose, furan-citric acid, and glucose-malic acid showed negative correlations. RP peppers were mostlystable for the first 6 months of storage, but after this month, due to changes in malic acid, aldehyde, glucose, andfructose, they displayed similar properties as CI. The organic compound content of CI peppers rapidly changed inthe first 3 months of storage and stayed almost stable for the remaining 9 months. Various ML methods wereeffectively employed in this study to examine the changes that different pepper spices exhibited in associationwith *** applications: Peppers, which are often used in food products for the purpose of bitterness, flavor, andcolor are mostly consumed after drying. The dried pepper is stored for a long time before consuming. Duringstorage, there are significant changes in the organic compound composition and pepper quality. In this study,revealing the change

AIM: To evaluate prospectively immediate intraocular pressure (IOP) changes after the intravitreal injection of ranibizumab, 2 and 4mg triamcinolone acetonide. METHODS: Patients who underwent intravitreal injection of 0.1mL (4mg) triamcinolone acetonide (TA, Group T4), 0.05mL (2mg) TA (Group T2) and 0.05mL (0.5mg) ranibizumab (Group R) comprised the study population. Overall, 229 eyes of 205 patients were injected. Fifty-four eyes (23.6%) were in Group T4, 69 eyes (30.1%) in Group T2 and 106 eyes (46.3%) in Group R. If IOP was less than 26mmHg immediately after the injection no further measurement was performed. If IOP was ≥26mmHg, IOP was remeasured till the reading was below 26mmHg at 5, 15 and 30 minutes. RESULTS: Immediately after the injection, the IOP of 28 eyes (51.9%) in Group T4, 22 eyes (31.9%) in Group T2 and 51 eyes (48.1%) in Group R were over 25mmHg. At 30 minutes, IOP of one eye (1.9%) in group T4, two eyes (2.9%) in group T2 and two eyes (1.9 %) in Group R were over 25mmHg. Immediate post-injection IOP was significantly higher in Group T4 and Group R when compared to Group T2 (P <0.001 and P <0.001, respectively). IOP was significantly higher in eyes without vitreous reflux when compared to those with vitreous reflux in all groups (P <0.001). CONCLUSION: IOP may remarkably increase immediately after the intravitreal injection of 2 or 4mg triamcinolone acetonide, and 0.5mg ranibizumab. Absence of vitreous reflux is the most important predicting factor for immediate IOP rise after the injection.

AIM： To investigate diabetic retinopathy（DR） literature using the Institute for Scientific Information（ISI） Web of Science（Wo S） database and to analyse the correlation results between socio-economic development datas and number of DR ***： The statistical analysis of the documents published during 1980-2014 was analysed. The data of this study were based on the database of Wo S. ＂Diabetic retinopathy＂ was used as the keywords to search the Wo S ***： The United States ranked first in the DR research with 1840 publications and 24.38% of the world production followed by England and Japan. Besides, the most productive country was Iceland. A high correlation was found between number of publications and 2014 gross domestic product（ GDP） values of 81 countries（r =0.800, P 〈0.001）. We found a significant correlation between number of publications and Human Development Index（HDI）（r =0.645, P =0.001）. There is a moderate correlation between people with diabetes and number of DR publications for 81 countries（r =0.514, P 〈0.01）. It could be analysed that estimated publication number with DR title will be 445 according to the regression curve constituted with cubic model in 2015（R2=1.000）.CONCLUSION： More DR studies have been published in developed countries, DR and other complications of diabetes have gradually increased in developing countries over recent decades. It can be expected that the number of DR studies will gradually increase in developing countries.
