A nationwide survey on the impact of COVID-19 pandemic on minimal invasive surgery in urology practice
(Wiley, 2021)Objective The beta-coronavirus (COVID-19) pandemic has changed the clinical approach of 93% of urologists worldwide, and this situation has affected the use of laparoscopic and robot-assisted laparoscopic methods, which ... -
Natural Radioactivity and Radiation Hazards in Coals Extracted in Amasya, Turkey
(POLISH ACAD SCIENCES INST PHYSICS, 2015)Radioactive nuclei were created at the beginning of the Universe and with a long half-life, are still present in Earth's crust. The radiations due to the radionuclides contribute to natural background radiation. This ... -
Neighborhood Structures and Continuities via Cubic Sets
(Mdpi, 2022)Cubic sets are a very useful generalization of fuzzy sets where one is allowed to extend the output through a subinterval of [0, 1] and a number from [0, 1]. In this article, we first highlight some of the claims made in ... -
A New Approach to Hausdorff Space Theory via the Soft Sets
(HINDAWI PUBLISHING CORP, 2016)The aim of this paper is to present the concept of soft bitopological Hausdorff space (SBT Hausdorff space) as an original study. Firstly, I introduce some new concepts in soft bitopological space such as SBT point, SBT ... -
A New Best Proximity Point Result with an Application to Nonlinear Fredholm Integral Equations
(Mdpi, 2022)In the current paper, we first introduce a new class of contractions via a new notion called p-cyclic contraction mapping by combining the ideas of cyclic contraction mapping and p-contraction mapping. Then, we give a new ... -
New Delphacidae Species (Hemiptera) for the Turkish Fauna
(Gazi Entomological Research Soc, 2023)Delphacids, are easily distinguished from the other families of Hemiptera by post tibial spurs, are harmful to many agricultural and cultural plants with their piercing-sucking mouthparts. Some of the species have economical ... -
NEW ESTIMATES FOR MEROMORPHIC FUNCTIONS
(Publications L Institut Mathematique Matematicki, 2021)A boundary version of the Schwarz lemma for meromorphic functions is investigated. For the function I-n f(z) = 1/z + Sigma(infinity)(k=2) k(n)c(k-2)z(k-2), belonging to the class of W, we estimate from below the modulus ... -
New interval oscillation criteria for second-order functional differential equations with nonlinear damping
(DE GRUYTER OPEN LTD, 2015)This paper concerns the oscillation problem of second-order nonlinear damped ODE with functional terms. We give some new interval oscillation criteria which is not only based on constructing a lower solution of a Riccati ... -
A new kind of F-contraction and some best proximity point results for such mappings with an application
(Tubitak Scientific & Technological Research Council Turkey, 2022)In this paper, we aim to present a new and unified way, including the previously mentioned solution methods, to overcome the problem in [7] for closed and bounded valued F-contraction mappings. We also want to obtain a ... -
New oscillation criteria for third-order differential equations with bounded and unbounded neutral coefficients
(Univ Szeged, Bolyai Institute, 2021)This paper examines the oscillatory behavior of solutions to a class of third-order differential equations with bounded and unbounded neutral coefficients. Sufficient conditions for all solutions to be oscillatory are ... -
New record and new species of lichenized fungal genus Candelariella M?ll. Arg. in Antarctica
(Polska Akad Nauk, Polish Acad Sciences, 2023)Previously, only three Candelariella species were known from Antarctica: C. aurella, C. flava and C. vitellina. After morphologically and phylogenetically examining our collections on soil from James Ross Island, located ... -
NONLOCAL STURM-LIOUVILLE PROBLEMS WITH INTEGRAL TERMS IN THE BOUNDARY CONDITIONS
(TEXAS STATE UNIV, 2017)We consider a new type Sturm-Liouville problems whose main feature is the nature of boundary conditions. Namely, we study the nonhomogeneous Sturm-Liouville equation p(x)u '' (x) + (q(x) - lambda)u = f(x) on two disjoint ... -
A note on common fixed points for (psi, alpha, beta)-weakly contractive mappings in generalized metric spaces
(SPRINGER INTERNATIONAL PUBLISHING AG, 2013)Very recently, Isik and Turkoglu (Fixed Point Theory Appl. 2013:131, 2013) proved a common fixed point theorem in a rectangular metric space by using three auxiliary distance functions. In this paper, we note that this ... -
NOTE ON SOME CLASSES OF HOLOMORPHIC FUNCTIONS RELATED TO JACK'S AND SCHWARZ'S LEMMA
(Univ Belgrade, Fac Electrical Engineering, 2022)In this paper we discuss holomorphic mappings f of the unit disc U and corresponding index defined as I-f (z) = zf'(z)/f(z). We are interested in finding f(z) bounds on the growth of functions f and related issues, if there ... -
A novel approach for calculating the item discrimination for Likert type of scales
(Izzet Kara, 2022)Item analysis is performed by developers as an integral part of the scale development process. Thus, items are excluded from the scale depending on the item analysis prior to the factor analysis. Existing item discrimination ... -
A Novel Binary Emperor Penguin Optimizer for Feature Selection Tasks
(Tech Science Press, 2022)Nowadays, due to the increase in information resources, the number of parameters and complexity of feature vectors increases. Optimization methods offer more practical solutions instead of exact solutions for the solution ... -
A novel nomogram and a simple scoring system for urinary leakage after percutaneous nephrolithotomy
(Brazilian Soc Urol, 2022)Introduction: The present study aimed to investigate the factors of prolonged urinary leakage (PUL) after percutaneous nephrolithotomy (PCNL) and develop a new and simple scoring system to predict it. Patients and Methods: ... -
Null Cartan curve variations in 3D semi-Riemannian manifold
(Hacettepe Univ, Fac Sci, 2021)The aim of this study is to investigate the variations of the Bishop frame curvatures for null Cartan curves in semi-Riemannian manifolds. The Killing equations in terms of the variations of the Bishop curvatures along the ... -
