ChinaBy taking full consideration of maturity (\(\tau_{1}\) represents the maturity of predator and \(\tau_{2}\) represents the maturity of top predator)
and the effects of environmental parameters, a new delayed three-species food chain model with stage structure and time-varying coefficients is
established. With the help of the comparison theorem and the technique of mathematical analysis, the positivity and boundedness of solutions of
the model are investigated. Furthermore, some sufficient conditions on the permanence and partial extinction of the system are derived.
Some interesting findings show that the delays have great impacts on the permanence for the system. More precisely, if \(\tau_{2}\in(n, +\infty)\),
then the system is partially extinct: on one hand, if \(\tau_{1}\in(0,n_{1})\) and \(\tau_{2}\in(n, +\infty)\), then the prey and predator species
will coexist, i.e., both the prey and predator species are always permanent, yet the top predator species will go extinct eventually.
On the other hand, if \(\tau_{1}\in(n_{4},+\infty)\) and \(\tau_{2}\in(n, +\infty)\), where \(n_{4}\) is greater than \(n_{1}\),
then all predator species will become extinct eventually. Numerical simulations are great well agreement with the theoretical results.http://www.isr-publications.com/jnsa/6346/download-permanence-and-partial-extinction-in-a-delayed-three-species-food-chain-model-with-stage-structure-and-time-varying-coefficientsInternational Scientific Research PublicationsJournal of Nonlinear Sciences and Applications(JNSA)ISSN 2008-1901101220171206Common fixed points for pairs of triangular \(\alpha\)-admissible mappings61926204http://dx.doi.org/10.22436/jnsa.010.12.06ENHaitham QawagnehSchool of mathematical Sciences, Faculty of Science and Technology, University Kebangsaan Malaysia, 43600 UKM, Selangor Darul Ehsan, MalaysiaMohd Salmi MD NooraniSchool of mathematical Sciences, Faculty of Science and Technology, University Kebangsaan Malaysia, 43600 UKM, Selangor Darul Ehsan, MalaysiaWasfi ShatanawiDepartment of Mathematics and General Courses, Prince Sultan University, Riyadh, Saudi ArabiaHabes AlsamirDepartment of Mathematics and General Courses, Aljouf University, Aljouf, Saudi ArabiaIn this paper, we introduce the notation of \((\alpha-\eta)-(\psi-\varphi)\)-contraction mappings defined on a set \(X\).

ChinaIn this paper, we propose a stochastic service-resource mutualism model with Lévy noises and harvesting. Under some assumptions, we study several dynamical properties of the model. We first obtain the thresholds between persistence and extinction for both the service species and the resource species. Then we give sharp sufficient conditions for stability in distribution of the model. Finally, we establish sufficient and necessary criteria for the existence of the optimal harvesting policy. The optimal harvesting effort and maximum of sustainable yield are also obtained. Our results reveal that the persistence, extinction, stability in distribution and optimal harvesting strategy have close relationships with the random noises.http://www.isr-publications.com/jnsa/6349/download-dynamics-of-a-stochastic-service-resource-mutualism-model-with-levy-noises-and-harvestingInternational Scientific Research PublicationsJournal of Nonlinear Sciences and Applications(JNSA)ISSN 2008-1901101220171206Identities of the degenerate Daehee numbers with the Bernoulli numbers of the second kind arising from nonlinear differential equation62196228http://dx.doi.org/10.22436/jnsa.010.12.08ENSung-Soo PyoDepartment of Mathematics Education, Silla University, Busan, Rep. of KoreaTaekyun KimDepartment of Mathematics, Kwangwoon University, Seoul, Rep. of KoreaSeog-Hoon RimDepartment of Mathematics Education, Kyungpook National University, Taegu, Rep. of KoreaIn [T.
