--The I Ching divination figures the answers to your question by following the rules of nature.--There must be a tracable track for all the things that happened around you. The I Ching divination could identify this andsignal you the unfolding new tracks lying ahead.>The I Ching, also called Book of Changes, is the most comprehensive and oldest oracle originated in ancient China. The I Ching (consists of 64 Hexagrams) signifies all situations and behaviors relating to nature and humans. The I Ching system is the integration of cosmology, philosophy, mathematics, symbolism and divination. It stresses the point of balance of opposites; indicates the changeable and the unchangeable which is that things change inevitably as times and conditions change while the laws of nature never change. Binary Number, the modern computer language, was invented by Gottfried Leibniz in 1679. Leibniz was deeply inspired by the I Ching. He recognized and wrote that his original concept of Binary System (using only the digit 0 and 1 throughout the computation) was corresponded to the I Ching's Trigram (binary number from 000 to 111) thus the Hexagrams (Gua). Yin (0) and Yang (1) are the basic binary configuration of the I Ching symbols. Furthermore, DNA (the hereditary material of all life) Genetic Code, which consists of 64-Triplet of nucleotides, is exactly analogous to the 64-Triplet System of the I Ching. Isn't that miraculous? Besides the above stated values, the philosophical and symbolic structures of the I Ching are also infinitely valued. The I Ching originally contains a system of divination. However the Numerology of I Ching, which was derived thousands of years later, significantly enriches the I Ching divinatory methods. It adds values of numeric, time, symbolism and the Five Elements (mutual generation and restriction between Metal, Fire, Water, Wood and Earth) to the original I Ching divination system, makes it simple to learn; swift to be used and miraculous the results. This book will focus on introducing this numerological way of divination. In order to allow beginners to straightforwardly understand this numerology in a short time, this book employs plenty of graphical images and charts to make it easy and simple to learn. All steps of divination are presented as visualized as possible. As a I Ching beginner or a lover, you will enjoy the great fun of using the Numerology of I Ching in life, in problem-solving or decision-making.

Optical coherence tomography (OCT) angiography is an important new imaging modality that is already being used by ophthalmologists in retina centers worldwide. It uses motion as intrinsic contrast, thus obviating the need to inject any intravenous dye. It uses infrared light that is invisible to the patient, and only requires few seconds per scan. This makes it both easier to use and much better tolerated by patients than traditional dye-based fluorescein angiography (FA) and indocyanine green (ICG) angiography. Inside Optical Coherence Tomography Angiography of the Eye Drs. David Huang, Bruno Lumbroso, Yali Jia, and Nadia Waheed include detailed information on clinical applications and fundamental principles needed to understand and use this new technology. This includes information on high-speed OCT systems, algorithms to extract flow contrast, the appearance of the normal eye, the findings in myriad diseases, and tips on how to deal with artifact and pitfalls. The 3-dimensional nature of OCT angiography provides visualization that was not possible before with either FA or ICG and readers will come to appreciate how this enables the visualization of previously difficult to image vascular beds such as the 4 retinal vascular plexuses (radial peripapillary, superficial, intermediate, and deep), the choriocapillaris, and the deeper choroidal vessels. Given its noninvasive nature and ease of use, OCT angiography imaging is rapidly taking an important place in everyday ophthalmology and may soon replace fluorescein angiography in everyday practice. Optical Coherence Tomography Angiography of the Eye is designed to be the definitive text on this cutting-edge technology for the retina specialist and comprehensive ophthalmologist.

Optical Coherence Tomography is an imaging technique which produces three-dimensional images of the tissues of the eye. The Clinical Guide to Angio-OCT: Non Invasive, Dyeless OCT Angiography presents the principles of Angio-OCT, discusses its clinical possibilities and demonstrates to the everyday OCT user the clinical utility of Angio-OCT.
