The G Connection

After 30 years of pioneering research with NASA, Joan Vernikos has written the first book to focus on the fundamental importance of gravity in maintaining youthful vigor. In it, she applies lessons learned from the experiences of U.S. astronauts and Soviet/Russian cosmonauts in space to ordinary people here on Earth. Highly practical, the "What You Can Do about It" section in each chapter is a comprehensive guide that will help young people, baby boomers, the elderly, and professionals make smart lifestyle choices. The G-Connection is written in down-to-earth and understandable language. Peppered with firsthand anecdotes from astronauts and interesting stories of Vernikos's own voyage of discovery, this book is both a fun and credible resource. The excitement for her work and ideas comes across clearly and is contagious. The reader finishes the book knowing what to do differently in his or her daily life to slow down or even reverse the aging process. "It is a treasure trove of ideas to a geriatrician"-Harold J. Guy, M.D., Professor of Geriatric Medicine, University of California San Diego Medical School, San Diego, California "The premise is plausible and the contents thoroughly referenced and well documented. It is written in a flowing style with humor and self-assurance and with language that never patronizes the reader."-Ralph Pelligra, M.D., NASA Ames Chief Medical Officer Moffett Field, California.

An accessible illustrated introducton to the networks we use every day, from Facebook and Google to WiFi and the Internet What makes WiFi faster at home than at a coffee shop? How does Google order search results? Is it really true that everyone on Facebook is connected by six steps or less? The Power of Networks answers questions like these for the first time in a way that all of us can understand. Using simple language, analogies, stories, hundreds of illustrations, and no more math than simple addition and multiplication, Christopher Brinton and Mung Chiang provide a smart and accessible introduction to the handful of big ideas that drive the computer networks we use every day. The Power of Networks unifies these ideas through six fundamental principles of networking. These principles explain the difficulties in sharing network resources efficiently, how crowds can be wise or not so wise depending on the nature of their connections, why there are many layers in a network, and more. Along the way, the authors also talk with and share the special insights of renowned experts such as Google’s Eric Schmidt, former Verizon Wireless CEO Dennis Strigl, and “fathers of the Internet” Vint Cerf and Bob Kahn.

Frank Arntzenius presents a series of radical ideas about the structure of space and time, and establishes a new metaphysical position which holds that the fundamental structure of the physical world is purely geometrical structure. He argues that we should broaden our conceptual horizons and accept that spaces other than spacetime may exist.

A smartphone is a portable device that combines mobile telephone and computing functions into one unit. It is a cellular telephone with an integrated computer and other features not originally associated with telephones such as an operating system, web browsing, multimedia functionality, the ability to run software applications, along with core phone functions such as voice calls and text messaging. Smartphones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer, proximity sensors, barometer, gyroscope, accelerometer and more), and support wireless communications protocols (such as Bluetooth, Wi-Fi, or satellite navigation). The best phones offer you everything you want from a mobile device. They deliver great cameras, the performance you need to multitask and enough battery life. The existing brands for Smartphones nowadays are: Samsung, Xiaomi, iPhone, Nokia, Huawei, Google Pixel, HTC, Asus, LG, Alcatel, Infinix, Panasonic, BlackBerry, Tecno, TCL, Oppo, Realme, Gionee, ZTE, Sony, Vivo, Lava, Lenovo, Microsoft, and Motorola. The most popular brands of smartphones are: Samsung, Apple, Huawei, Xiaomi, Oppo, Vivo, Realme, Sony. Choosing a smartphone for yourself not easy task. Factors that affect your choices of Smart phone are: price range, features, the operating system you prefer, the important specs for you.

This proceedings volume addresses advances in global optimization—a multidisciplinary research field that deals with the analysis, characterization and computation of global minima and/or maxima of nonlinear, non-convex and nonsmooth functions in continuous or discrete forms. The volume contains selected papers from the third biannual World Congress on Global Optimization in Engineering & Science (WCGO), held in the Yellow Mountains, Anhui, China on July 8-12, 2013. The papers fall into eight topical sections: mathematical programming; combinatorial optimization; duality theory; topology optimization; variational inequalities and complementarity problems; numerical optimization; stochastic models and simulation and complex simulation and supply chain analysis.

Does success in school protect teenagers from drug use? Does drug use impair scholastic success? This book tackles a key issue in adolescent development and health - the education-drug use connection. The authors examine the links and likely causal connections between educational experiences, delinquent behavior, and adolescent use of tobacco, alco
