Introduction

The objective of this session is to introduce the subject of software engineering. When you have read this session you will understand what software engineering is and why it is important, know the answers to key questions which provide an introduction to software engineering, understand ethical and professional issues which are important for software engineers.

High School Education in the United States of America:

As Nelson Mandela, the first democratically elected president of South Africa and a leader in South Africa’s fight for equality, once said, “Education is the most powerful weapon you can use to change the world.” Educated people bring about peace, prosperity, and progress for the entire population’s benefit. Luckily, a great emphasis is placed upon education in the United States of America because higher education is central to the world’s ability to make positive changes for each of its people. This article will cover the American school system, international students in America, financial aid options, and steps to college admission.

Cell cycle regulation in the budding yeast

Cell cycle is regulated cooperatively by several genes. The underlying regulatory mechanism of the cell cycle remains one of the hottest research topics of life science. In this talk, the cell cycle regulatory mechanism, especially the dynamic role of feedback loops will be presented taking the budding yeast as a target system. Based on the mathematical model developed by Chen et al. (MBC, 11, 369) the bifurcation diagram that shows the locations of stable and unstable solutions will be constructed at first. It is a kind of ‘dynamic load map’, attracted toward the stable solutions and repelled away from the unstable solutions on the map. The bifurcation diagram allows us to understand the regulatory mechanism of the ‘START’ transition, the initiation of a new round of a cell cycle, and the ‘FINISH’ transition, the completion of a cell cycle and returning back to the initial state. For example, the ‘start transition’ occurs at the point where the dynamics load map in fig 6. changes from a stable fixed point solution (blue line) to an oscillatory solution (green lines).
