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 ... -
A New Kind of Vector Space: Soft Vector Space
(SOUTHEAST ASIAN MATHEMATICAL SOC-SEAMS, 2016)Molodtsov introduced the concept of soft sets. In this paper, we present the definition of soft vector spaces and construct some basic properties by using vector spaces and Molodtsov's definition of soft sets. We introduce ... -
New metallophthalocyanines including benzylphenoxy groups and investigation of their organic-field effect transistor (OFET) features
(Elsevier Sci Ltd, 2022)In this study, metal and metal-free novel phthalocyanines containing peripheral and non-peripheral tetra 2-ben-zylphenoxy groups were synthesized. The compounds were characterized by UV-Vis, FT-IR, H-1 NMR, and MALDI-TOF ... -
A New Method of Spectrum Sensing in Cognitive Radio for Dynamic and Randomly Modelled Primary Users
(TAYLOR & FRANCIS LTD, 2019)In this study, a new spectrum sensing method for cognitive radio (CR) is proposed for primary user (PU) signals which are modelled as random with unknown power. It is also assumed that, being dynamic, the PU might exhibit ... -

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 ... -
A new pseudo random number generator based on Chebyshev maps and parameter switching
(Institute of Electrical and Electronics Engineers Inc., 2018)Digital implementations of chaotic systems are periodic and they are degraded versions of the original chaotic system. Hence, all digital pseudo random number generators based on chaotic systems inherently contain several ... -
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 ... -
New Schiffbases with a 2,6-bis(2-aminophenylthio)pyridine moiety acting as glutathione reductase activator and inhibitors: Synthesis and molecular docking studies
(Elsevier, 2022)2,6-bis(2-aminophenylthio)pyridine was synthesized and identified by x-ray diffraction method. Its new Schiffbases (H2L1, H2L2, L-3 and L-4) were synthesized and characterized by elemental analysis, FT-IR, LC-MS, H-1 NMR ... -
A new selenium-based RAFT agent for surface-initiated RAFT polymerization of 4-vinylpyridine
(ELSEVIER SCI LTD, 2013)A new selenium-based reversible addition-fragmentation chain transfer (RAFT) agent, 4-cyanopentanoic acid diselenobenzoate (RAFT-Se), was synthesized and utilized in the surface-initiated RAFT polymerization of 4-vinylpyridine ... -
A New Soft Set Operation: Complementary Soft Binary Piecewise Intersection (?) Operation
(2023)The soft set theory developed by Molodtsov has been applied both theoretically and practically in many fields. It is a useful piece of mathematics for handling uncertainty. Numerous variations of soft set operations have ... -
A new species of Tinna (Hemiptera: Heteroptera: Reduviidae) from Nigeria
(Magnolia Press, 2021)Tinna schoenitzeri sp. nov. (Hemiptera: Heteroptera: Reduviidae: Emesinae: Leistarchini) is described from Nigeria. Digital macrophotographs and scanning electron micrographs of the new species are given. -
New syntaxa from the west part of Central Anatolia

A new trend in preparing for foreign language exam (YDS) in Turkey: Case of WhatsApp in mobile learning
(Springer New York LLC, 2019)This study has sought to reveal perceptions towards the employment of WhatsApp in foreign language learning, especially preparing for a national academic language exam. In this sense, this study is supposed to make ... -
A NEW TYPE STURM-LIOUVILLE PROBLEM WITH AN ABSTRACT LINEAR OPERATOR CONTAINED IN THE EQUATION
(Taylor & Francis Ltd, 2022)In this study we shall introduce to the consideration a new type Sturm-Liouville problem, which differs from the standard problems in that it contain nondifferential term in the equation. Namely, the equation contains an ... -
A New View on AG-Groupoid Theory via Soft Sets for Uncertainty Modeling
(UNIV NIS, FAC SCI MATH, 2018)In this paper, the concepts soft union AG-groupoids, soft union left (right, two-sided) ideals, (generalized) bi-ideals, interior and quasi-ideals in AG-groupoids are introduced with many illustrating examples and their ... -
