Fractional approach to evolution of the magnetic field lines near the magnetic null points
Durmaz, Hasan; Ozdemir, Zehra; Sekerci, Yadigar (Iop Publishing Ltd, 2024)In this work, the magnetic reconnection model near null points in 3D space will be investigated using fractional calculations in the 3D magnetohydrodynamic framework. For the initial magnetic configuration (without external ... -
Global Warming Can Lead to Depletion of Oxygen by Disrupting Phytoplankton Photosynthesis: A Mathematical Modelling Approach
Sekerci, Yadigar; Petrovskii, Sergei (MDPI, 2018)We consider the effect of global warming on the coupled plankton-oxygen dynamics in the ocean. The net oxygen production by phytoplankton is known to depend on the water temperature and hence can be disrupted by warming. ... -
The impact of vaccination strategy on the spatiotemporal pattern dynamics of a COVID-19 epidemic model
Sekerci, Yadigar; Khoshnaw, Sarbaz H. A. (Springer Heidelberg, 2024)In the last 3 years, mathematical modelling and computational simulations have been used to discuss and estimate key transmission parameters of the spreading COVID-19 pandemics. There are several major factors that have ... -
Pattern Formation in a Model Oxygen-Plankton System
Sekerci, Yadigar; Petrovskii, Sergei (MDPI, 2018)Decreasing level of dissolved oxygen has recently been reported as a growing ecological problem in seas and oceans around the world. Concentration of oxygen is an important indicator of the marine ecosystem's health as ... -
Regime shifts and ecological catastrophes in a model of plankton-oxygen dynamics under the climate change
Petrovskii, Sergei; Sekerci, Yadigar; Venturino, Ezio (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2017)It is estimated that more than a half of the total atmospheric oxygen is produced in the oceans due to the photosynthetic activity of phytoplankton. Any significant decrease in the net oxygen production by phytoplankton ... -
Stability of spatial patterns in a diffusive oxygen-plankton model with time lag effect
Gokce, Aytul; Yazar, Samire; Sekerci, Yadigar (Elsevier, 2022)Although marine ecosystem is a highly complex phenomenon with many non-linearly interacting species, dissolved oxygen and plankton among these have perhaps the most fundamental relationship not only for the protection of ... -
Temporal Response of Predator-Prey System with the Allee Effect
Sekerci, Yadigar (Bilecik Şeyh Edebali Üniversitesi, 2020)Temporal dynamics of a predator-prey model, in which predator mortality rate varies linearly in time, is considered with the assumption that prey growth is stressed by the strong Allee effect. In this work, temporal structure ...
