On KU-Algebras containing (α, β)-US soft sets
Moin A. Ansari,Ali N.A. Koam,Azeem Haider 강원경기수학회 2020 한국수학논문집 Vol.28 No.1
In this paper, we connect $(\alpha, \beta)$ union soft sets and their ideal related properties with $KU$-algebras. In particular, we will study $(\alpha, \beta)$-union soft sets, $(\alpha, \beta)$-union soft ideals, $(\alpha, \beta)$-union soft commutative ideals and ideal relations in $KU$-algebras. Finally, a characterization of ideals in $KU$-algebras in terms of $(\alpha, \beta)$-union soft sets have been provided.
Generalized rough approximations in ordered LA-semigroups
Moin Akhtar Ansari 원광대학교 기초자연과학연구소 2018 ANNALS OF FUZZY MATHEMATICS AND INFORMATICS Vol.15 No.1
In this paper, the concept of generalized rough set theory is applied to the theory of ordered LA-semigroups by using pseudoorder and some of their combined results have been shown. Properties of rough two-sided ideals, rough bi-ideals and rough prime ideals in ordered LA-semigroups have been studied and discussed on the basis of pseudoorder of relations.
Sources of Cost Saving Opportunities in Highway Construction Quality Assurance Practices
Uddin, Mohammad Moin,Newland, James Korea Institute of Construction Engineering and Ma 2018 Journal of construction engineering and project ma Vol.8 No.1
US transportation agencies are dealing with shrinking budgets, limited work forces, and deteriorating infrastructure. In order to cope with funding uncertainty, state highway agencies are now looking into their own organizations and identifying programs, practices, and processes that have potential for cost saving. A quality assurance (QA) program is an integral part of highway construction and ensures a project's contracted level of quality. The cost of quality (conforming and nonconforming) can constitute a sizable part of total construction cost. As the quality assurance programs evolved, various practices and processes were developed over time and later adopted by state highway agencies. These practices and processes include different QA standards and specifications, varying testing methods, central testing lab vs. on site testing, performance based vs. prescribed quality assurance practices, implementation of innovative quality assurance practices, etc. Therefore, there is an opportunity to assess different QA strategies and recommend those practices that are effective and cost efficient. A national survey was conducted by the authors, which provided a detailed mapping of various QA practices and processes used as part of QA programs and identified areas where agencies can focus on for cost savings. The survey found that QA sampling and testing plans, optimization of sampling plans, optimization of QA standards and specifications, and implementation of innovative test methods and processes are the main areas the agencies should focus to lean the current QA programs.
Effects of Interleukin-13 and Montelukast on the Expression of Zonula Occludens-1 in Human Podocytes
박세진,하태선,Moin A. Saleem,남자애,신재일 연세대학교의과대학 2015 Yonsei medical journal Vol.56 No.2
Purpose: The aim of this study was to investigate whether pathologic changes in zonula occludens-1 (ZO-1) are induced by interleukin-13 (IL-13) in the experimentalminimal-change nephrotic syndrome (MCNS) model and to determine whether montelukast, a leukotriene receptor antagonist, has an effect on ZO-1 restorationin cultured human podocytes. Materials and Methods: Human podocytescultured on bovine serum albumin-coated plates were treated with different doses of IL-13 and montelukast and then examined for distribution using confocal microscopy and for ZO-1 protein levels using Western blotting. Results: ZO-1 was internalized and shown to accumulate in the cytoplasm of human podocytes in an IL-13 dose-dependent manner. High doses (50 and 100 ng/mL) of IL-13 decreasedthe levels of ZO-1 protein at 12 and 24 h (both p<0.01; n=3), which were significantly reversed by a high dose (0.5 μM) montelukast treatment (p<0.01; n=3). Conclusion: Our results suggest that IL-13 alters the expression of ZO-1, and such alterations in the content and distribution of ZO-1 may be relevant in the pathogenesis of proteinuria in the MCNS model.
Localization of the Optic Disc Center in Retinal Images Based on the Harris Corner Detector
Amin Dehghani,Mohammad-Shahram Moin,Mohammad Saghafi 대한의용생체공학회 2012 Biomedical Engineering Letters (BMEL) Vol.2 No.3
Purpose Localizing the optic disc and its center is the first step of most identification, segmentation algorithms and diagnosing some diseases on fundus photographs such as diabetic retinopathy. Despite the importance of optic disc localization, there is not very accurate and fast method for localizing the center of optic disc in retinal images. Therefore,we propose a robust and fast algorithm for localizing the center of optic disc. Methods Based on the property of optic disc, vessels originate from the center of optic disc and the number of the vessels in the vicinity of optic disc is more than others regions in the retinal images. Therefore, we can see the largest number of corners and bifurcations around the optic disc in the retinal images. In this paper, a robust method based on Harris corner detector is proposed. Using the Harris corner detector, corners and bifurcations are found in the retinal images. Then, we use a moving window near the size of optic disc to count the number of corners. Finally, the center of windows in which the high number of corners are located, is obtained and the mean of these centers is considered as the center of optic disc. The DRIVE, STARE and a local dataset including 273 retinal images are used to evaluate the proposed algorithm. Results The success rate is 97.5%, 87.65% and 97.8% for DRIVE, STARE and a local dataset. The average distance between the estimated and the manually identified optic disc centers is 4.61, 11 and 9 pixels for the DRIVE, STARE and local dataset respectively. Comparing the results of our proposed method and counterpart methods verifies the effectiveness of the proposed method. Conclusions In this paper, we proposed a new method for localizing the center of optic disc based on corners and bifurcations obtained using Harris corner detector. Comparing the results of our proposed method and counterpart methods verifies the effectiveness of the proposed method.
Current concepts of the podocyte in nephrotic syndrome
( Wen Y. Ding ),( Moin A. Saleem ) 대한신장학회 2012 Kidney Research and Clinical Practice Vol.31 No.2
Nephrotic syndrome is a disorder of the glomerular filtration barrier, and central to the filtration mechanism of the glomerular filtration barrier is the podocyte. We are starting to better understand how this cell, with its unique architectural features, fulfils its exact filtration properties. The multiprotein complex between adjacent podocyte foot processes, the slit diaphragm, is essential to the control of the actin cytoskeleton and cell morphology. Many of the proteins within the slit diaphragm, including nephrin, podocin, transient receptor potential-6 channel, and a-actinin-4, have been identified via genetic studies of inherited nephrotic syndromes. Signaling from slit diaphragm proteins to the actin cytoskeleton is mediated via the Rho GTPases. These are thought to be involved in the control of podocyte motility, which has been postulated as a focus of proteinuric pathways. Nephrotic syndrome is currently treated with immunosuppressive therapy, with significant adverse effects. These therapies may work in nephrotic syndrome due to specific effects on the podocytes. This review aims to describe our currentunderstanding of the cellular pathways and molecules within the podocyte relevant to nephrotic syndrome and its treatment. With our current knowledge of the cellular biology of the podocyte, there is much hope for targeted therapies for nephrotic syndromes.
Partially degenerate poly-Bernoulli polynomials associated with Hermite polynomials
WASEEM A. KHAN,Moin Ahmad 장전수학회 2018 Advanced Studies in Contemporary Mathematics Vol.28 No.3
In this paper, we derive generating functions for the partially degenerate Hermite poly-Bernoulli polynomials and investigate some properties of these polynomials related to the Stirling numbers of the second kind. Further, we derive the summation formulae and general symmetry identities for that polynomials by using different analytical means on its generating function. Also, generating functions and summation formulae for the polynomials related to partially degenerate Hermite poly- Bernoulli polynomials are obtained as applications of main results.
