Описание: In the last decades a remarkable renaissance has materialized in insect morphology, mainly triggered by the development of new cutting-edge technologies. This is an exciting time for biological synthesis where the mysteries and data derived from genomes can be combined with centuries of data from morphology and development. And, now, more than ever, detailed knowledge of morphology is essential to understanding the evolution of all groups of organisms. In this “age of phylogenomics” researchers rely on morphological data to support molecular findings, test complex evolutionary scenarios, and for placing fossil taxa. This textbook provides an in-depth treatment of the structures and the phylogeny of the megadiverse Hexapoda. The first part presents an up-to-date overview of general insect morphology with detailed drawings, scanning electron micrographs, and 3-D reconstructions. Also included is a chapter covering innovative morphological techniques (e.g., µ-computer tomography, 3-D modeling), brief treatments of insect development and phylogenetic methods, and a comprehensive morphological glossary. The second part is of a modern synthesis of insect systematics that includes taxon-specific morphological information for all Orders. The work is an invaluable reference for students and researchers working in all facets of biology and is a must for evolutionary biologists. A detailed understanding of morphology is essential in unraveling phylogenetic relationships and developing complex evolutionary scenarios. Increasingly researchers in phylogenomics are re/turning to morphological data to support their findings, while the development of new cutting-edge technologies has further increased interest in this growing field. This definitive handbook provides an in-depth treatment of insect morphology. The first part presents an up-to-date overview of insect morphology with detailed drawings, brilliant scanning electron micrographs and 3-D reconstructions as interactive PDFs. Thisis complemented by a chapter on innovative morphological techniques (e.g., µ-computer tomography, 3-D modeling) and a comprehensive morphological glossary. The second part treats the state of the art in insect systematics and includes taxon-specific morphological information for all orders. Systematicsare treated formally, with for example the arguments for relationships (“apomorphies”) always listed explicitly. The work is a useful reference for students and researchers working in different fields of biology and a must for those dealing with insects from an evolutionary perspective.

Описание: Algebra is taught from elementary school to college and beyond. Algebraic problems present a significant portion in all math competitions including MathCounts, AMC, AIME, USAMO and so on. Therefore, solving competition level algebraic problems is a must-master skills for every contest contender. Algebra includes a wide range of topics and techniques. Some of them may be related to advanced mathematical theorems and tools. Therefore, it is impossible to cover all of them in one book. However, middle school and high school level competitions usually do not require advanced mathematics. Instead, the emphasis is on the applications of basic algebraic skills in a flexible and effective way to solve complex problems. As a result, it is a wise strategy to thoroughly understand the most important topics and drill down into details of related solving techniques in order to improve one's skill and test performance. This book covers three basic but important topics: equation, sequence and function. While these topics are all taught in schools, there are some competition specific techniques which deserve a systematic discussion. Taking Vieta's theorem as an example. While polynomial transformation is a well known method to evaluate expressions such as $x_1 2+x_2 2$, there are several other powerful techniques. They can be used to evaluate some complex expressions in a more efficient and less error-prone way. These expressions can have high power such as $x_1 {7}+x_2 {7}$, or are asymmetric such as $5x_1 3 + 3 x_2 5$. In fact, the latter asymmetric expression can present a challenge to many students who only know the polynomial transformation method. In addition to expression evaluation, Vieta's theorem can also be used to solve some seemingly unrelated problems. Such problems are among top hits in various math competitions. Sequence is another good example. Most students understand the two basic types of sequences, namely, arithmetic and geometric. Though the vast majority of sequence related problems in math contests can be converted to these basic types, finding such conversion may be a demanding task which is usually not discussed in classrooms. Meanwhile, in order to become a strong competitor, one must also understand a few additional more complex sequences especially those defined recursively. They are beyond the scope of school textbooks, but are discussed in this book. The goal of this book is to give an organized in-depth discussion on competition level techniques. Fully understanding these techniques will help students to quickly recognize and solve these types of problems. It will also lay down a solid foundation for them to solve other problems whose solutions require these algebraic techniques as critical stepping stones.

Описание: In Physiognomy in Ming China: Fortune and the Body, Xing Wang investigates the intellectual and technical contexts in which the knowledge of physiognomy (xiangshu) was produced and transformed in Ming China (1368-1644 C.E.). Known as a fortune-telling technique via examining the human body and material objects, Xing Wang shows how the construction of the physiognomic body in many Ming texts represent a unique, unprecedented ‘somatic cosmology’. Applying an anthropological reading to these texts and providing detailed analysis of this technique, the author proves that this physiognomic cosmology in Ming China emerged as a part of a new body discourse which differs from the modern scholarly discourse on the body.
Описание: Based on Chinese historical data collected over the past three thousand years, the articles in the volume investigate the development of new grammatical categories and the process of lexicalization and grammaticalization of unique grammatical words.

"Number Four will have a difficult life." These are the words that were uttered upon Ting-xing Ye’s birth. Soon this prophecy would prove only too true. . . .
Here is the real-life story about the fourth child in a family torn apart by China’s Cultural Revolution. After the death of both of her parents, Ting-xing and her siblings endured brutal Red Guard attacks on their schools and even in their home. At the age of sixteen, Ting-xing is exiled to a prison farm far from the world she knows.
How she struggled through years of constant terror while keeping her spirit intact is at the heart of "My Name Is Number 4." Haunting and inspiring, Ting-xing Ye’s personal account of this horri?c period in history is one that no reader will soon forget.

Описание:
Welcome to the Math All Star series These books are for middle school and high school students who are motivated to participate in math competitions such as MathCounts, AMC, and AIME. Their coaches may also find these books useful.
The website, http: //www.mathallstar.org, provides extra practice problems and serves as a highly recommended supplemental learning resource.
Indeterminate Equation
Indeterminate equations is a popular subject in math competitions at all levels, from AMC 8 to IMO. For example, in 2015 alone, both IMO and USAMO have an indeterminate equation problem out of 6 in total. Meanwhile, AIME and AMC12/10/8 also have various related questions.
Despite its popularity, how to solve indeterminate equations is rarely discussed in classrooms. As a result, many students are lack of necessary knowledge and skills to tackle such problems. This book is to discuss various types of indeterminate equations and corresponding solving techniques. Upon completing this book, readers should be able to recognize and solve these indeterminate equations comfortably.
Table of contents and pre-assessment are both available at the website www.mathallstar.com.
