    Mathematical assessment of the role of temperature on desert locust population dynamics. by Dejen Ketema Mamo, Mathew N Kinyanjui, Nourridine Siewe

    Published 2025-01-01
    “…Numerical simulations demonstrate the significant impact of temperature on population growth, with optimal conditions promoting rapid development and increased survival, while extreme temperatures can hinder population growth and trigger phase transitions. By providing a deeper understanding of temperature-driven population shifts, this model enhances the ability to predict locust outbreaks, optimize control strategies, and reduce the socio-economic and ecological impacts of locust invasions.…”

    Modification of surface layers by high energy treatment by M. N. Vereschagin, S. N. Tselueva, M. Yu. Tseluev

    Published 2019-08-01
    “…The nature of heating, which is determined by the rate of change of temperature, temperature gradients, the time to reach the temperatures of structural and phase transitions, is different depending on the properties of the material being processed and the processing conditions.When modifying the surface layers by high-energy processing by changing the power and time of exposure to laser radiation, you can get a wide range of structural states of the treated surface areas of the material.It is shown that the shape of TVP diagrams and cooling curves of precision alloys on the surface of a two-layer metal system after heating them with laser radiation are determined by the competition of two processes acting in opposite directions: an increase in the driving force of the crystallization process with an increase in supercooling and a decrease in the surface of atoms.The method of surface modification by moving laser radiation allows to obtain amorphous functional layers of precision alloys on the surface of metal products.…”

    Phenomenological construction of metal photonic topological insulators based on theory of characteristic modes by Lili Dai, Jie Meng, Weiwen Li

    Published 2025-01-01
    “…Thus, in this paper, it is believed that, if the crossing avoidance modes of metal photonic crystal cells are annular, the metal photonic crystal should have the performance of photonic topological phase transitions (TPTs) in this band. Based on CMA, a spoof surface plasmon periodic structure is constructed to achieve electromagnetic TPTs with the photonic valley Hall effect. …”
