Data structures is a key course for computer science and related majors. This book presents a variety of practical or engineering cases and derives abstract concepts from concrete problems. Besides basic concepts and analysis methods, it introduces basic data types such as sequential list, tree as well as graph. This book can be used as an undergraduate textbook, as a training textbook or a self-study textbook for engineers.

The systematic description starts with basic theory and applications of different kinds of data structures, including storage structures and models. It also explores on data processing methods such as sorting, index and search technologies. Due to its numerous exercises the book is a helpful reference for graduate students, lecturers.

This book summarizes the latest archeological findings on Liangzhu culture and outlines the rise and fall of Liangzhu society in terms of its environment, flora and fauna. In addition, it seeks to analyze the characteristics of animal breeding and agricultural cultivation in Liangzhu from the perspectives of archeobotany and archeozoology. In turn, it explores the dietary structure and population density, reaching the bold conclusion that the dramatic increase in population gave rise to environmental deterioration and to natural disasters that eventually destroyed the Liangzhu culture.

"Comprehensive College Algebra: Building Mathematical Insights Through Logic and Exercises" is a concise, but rigorous, introduction to college algebra that features a variety of exercises designed to help students build up mathematical thinking, master mathematical skills, and develop mathematical insights.
The book begins with an introduction of sets and the number systems. This foundational knowledge prepares students for the subsequent chapters, and skill development in areas including: Polynomials; Factoring; Linear Equations and Inequalities; Rational Expressions; Coordinate Systems and Lines; Radicals; Quadratic Equations; Conic Sections; and Exponential and Logarithmic Functions.
All chapters emphasize clear definitions, which are presented in context, as well as propositions and theorems. Comprehensive review questions are included at the end of the book to allow for independent practice.
