Title: A theory of negative prices for exhaustible resources
Abstract: The recent plunge of WTI crude oil prices into negative territory for the first time has drawn a lot of attention and controversy around the world. In this talk, we propose a novel equilibrium model of exhaustible resources and reveal that negative equilibrium prices for exhaustible resources can be generated by combining storage costs, production adjustment costs, and imbalance between supply and demand. Our model is able to calibrate the steep futures curve of WTI crude oil observed on April 20, 2020. This work is jointly with Steven Kou and Cong Qin.

Title: Recent Trends and Advances in Radio Frequency and Microwave Technologies
Abstract: Microwaves are a type of electromagnetic radiation, as are radio waves, ultraviolet radiation, X-rays and gamma-rays. Microwaves have a range of applications, including communications, radar and, perhaps best known by most people, cooking. Microwaves have frequencies ranging from about 300 MHz to 300 GHz. The aim of this presentation is to briefly discuss the significant progress of microwave engineering and technology achieved in recent years, heralding an era rich in engineering discovery and innovations in the area of microwave technology. In this speech, recent trends of advanced research of various crucial applications in microwave engineering will be discovered. It covers from advanced wireless communications, material characterization, wireless energy transmission, microwave sensor and microwave imaging.

Title: Modeling and Simulation for Solid-State Dewetting Problems
Abstract: In this talk, I present sharp interface models with anisotropic surface energy and a phase field model for simulating solid-state dewetting and the morphological evolution of patterned islands on a substrate in two and three dimensions.
We show how to derive the sharp interface model via thermovariation dynamics, i.e. variation of the interfacial energy via an open curve with two triple points moving along a fixed substrate. The sharp interface model tracks the moving interface explicitly and it is very easy to be handled in two dimensions via arc-length parametrization. The phase field model is governed by the Cahn-Hilliard equation with isotropic surface tension and variable scalar mobility and it easily deals with the complex boundary conditions and/or complicated geometry arising in the solid-state dewetting problem. Since the phase field model does not explicitly track the moving surface, it naturally captures the topological changes that occur during film/island morphology evolution. Efficient and accurate numerical methods for both sharp interface models and phase field models are proposed. They are applied to study numerically different setups of solid-state dewetting including short and long island films, pinch-off, hole dynamics, semi-infinite film, etc. Our results agree with experimental results very well. This talk is based on joint works with Wei Jiang, David J. Srolovitz, Carl V. Thompson, Yan Wang and Quan Zhao.
