摘要：

干细胞再生是维持组织稳态的重要生物过程；干细胞再生失调可能导致细胞数量波动的动态疾病。细胞异质性和可塑性对于组织稳态的动态平衡是必要的；然而，这些特征如何影响干细胞再生过程的振荡动力学仍然知之甚少。这里，基于细胞异质性和表观遗传状态随机转变的异质干细胞再生数学模型，我们通过分支分析和数值模拟研究振荡解的条件。我们的结果显示：动力学速率、细胞异质性和可塑性相关不同参数的变化导致各种模型系统动力学。我们展示：正如我们在同质干细胞再生系统中所看到的那样，引入细胞异质性和可塑性可以导致振荡动力学。然而，增加细胞异质性和可塑性旨在在某些条件下维持组织稳态。目前的研究是对细胞异质性和可塑性如何影响干细胞再生动力学的初步研究，许多问题仍有待在生物学和数学上进一步研究。

Topic: Energy related topics at the University of Zagreb and Role of EnergyStorage Technologies in Future Energy Systems

Time & Date: 3:00-5:00 PM，November 30 (Thursday)

Venue: Room 108, Teaching D

Speaker: Dr. Hrvoje Mikulčić, University of zagreb, Croatia

Host: Prof. Dongxu JI, The Chinese University of Hong Kong, Shenzhen

Abstract: 

The Faculty of Mechanical Engineering is the oldest and the largest faculty in the field of mechanical engineering in Croatia with almost century-old tradition. The research group is very active in project and research activities on modelling of integration of renewable energy sources in integrated energy systems and promotion of transition towards smart and sustainable energy generation and use.  

Energy storage technologies are indispensable elements in the evolution of future energy systems, pivotal in various critical facets that shape the sustainability and efficiency of the energy landscape. These technologies play a fundamental role in integrating intermittent renewable sources like solar and wind power by capturing surplus energy during peak generation and releasing it during periods of low production. Furthermore, they contribute significantly to grid stabilization, reducing congestion and offering essential frequency regulation for enhanced overall grid stability and reliability.

Managing peak demand periods is another crucial function of energy storage systems. By storing surplus energy during low-demand periods and supplying it during peak hours, these technologies alleviate strain on the grid and mitigate the necessity for additional power generation facilities. Additionally, they act as reliable backup power sources during grid failures or emergencies, ensuring uninterrupted services and fortifying the resilience of energy infrastructure. In this talk, Ongoing research and development related with energy storage in the group will be introduced.  

Bios:

Dr. Hrvoje Mikulčić obtained his Ph.D. thesis in 2015 at the Department of Power Engineering, Energy and Environment, Faculty of Mechanical Engineering and Navel Architecture, University of Zagreb.

His main research area includes: numerical modelling of heat and mass flow, multi-phase reacting flow, solid fuel combustion, pollutant formation, energy system analysis, renewable energy, carbon capture and utilization, green ammonia.

He is an author of 102 scientific papers in scientific journals (SCI). His current Scopus H-index is 33 with 3280 citations. In August 2021, his scientific excellence has been confirmed by the updated Stanford authors’ list of world’s top-scientists. He has been listed in the top 2% of world’s scientists for a single year, making it to the list as one of the youngest scientists on that list.
