Dynamics of Free Dendritic Growth
نویسنده
چکیده
The purpose of this essay is to provide an overview of the dynamics of pattern formation in solidifying systems. The primary focus is dendritic crystallization during the solidiication of a pure melt. A review is given of the classic experiments performed on succinonitrile. The standard model of solidiication is then introduced and the steady state Ivantsov solution is discussed. The use of the marginal stability hypothesis and solvability theory to investigate the actual operating state (growth rate and shape) of dendrites is summarized. The essay concludes with a discussion of the use of phase-eld models to numerically simulate dentritic growth.

Human epidermal growth factor receptor 2 (HER2) is a member of the epidermal growth factor receptor family having tyrosine kinase activity. Overexpression of HER2 usually causes malignant transformation of cells and is responsible for the breast cancer. In this work, the virtual screening, molecular docking, quantum mechanics and molecular dynamics methods were employed to study protein–ligand ...

In this paper, a model-free reinforcement learning-based controller is designed to extract a treatment protocol because the design of a model-based controller is complex due to the highly nonlinear dynamics of cancer. The Q-learning algorithm is used to develop an optimal controller for cancer chemotherapy drug dosing. In the Q-learning algorithm, each entry of the Q-table is updated using data...
متن کاملThe X-Linked Autism Protein KIAA2022/KIDLIA Regulates Neurite Outgrowth via N-Cadherin and δ-Catenin Signaling
Our previous work showed that loss of the KIAA2022 gene protein results in intellectual disability with language impairment and autistic behavior (KIDLIA, also referred to as XPN). However, the cellular and molecular alterations resulting from a loss of function of KIDLIA and its role in autism with severe intellectual disability remain unknown. Here, we show that KIDLIA plays a key role in neu...
