Isotope-Based Quantum Information
by Vladimir G. PlekhanovThe present book provides to the main ideas and techniques of the rapid progressing field of quantum information and quantum computation using isotope - mixed materials. It starts with an introduction to the isotope physics and then describes of the isotope - based quantum information and quantum computation. The ability to manipulate and control electron and/or nucleus spin in semiconductor devices provides a new route to expand the capabilities of inorganic semiconductor-based electronics and to design innovative devices with potential application in quantum computing. One of the major challenges towards these objectives is to develop semiconductor-based systems and architectures in which the spatial distribution of spins and their properties can be controlled. For instance, to eliminate electron spin decoherence resulting from hyperfine interaction due to nuclear spin background, isotopically controlled devices are needed (i.e., nuclear spin-depleted). In other emerging concepts, the control of the spatial distribution of isotopes with nuclear spins is a prerequisite to implement the quantum bits (or qbits). Therefore, stable semiconductor isotopes are important elements in the development of solid-state quantum information. There are not only different algorithms of quantum computation discussed but also the different models of quantum computers are presented. With numerous illustrations this small book is of great interest for undergraduate students taking courses in mesoscopic physics or nanoelectronics as well as quantum information, and academic and industrial researches working in this field.
Issues and Challenges in Artificial Intelligence
by Zdzisław S. Hippe Juliusz L. Kulikowski Teresa Mroczek Jerzy WtorekThe importance of human-computer system interaction problems is increasing due to the growing expectations of users on general computer systems capabilities in human work and life facilitation. Users expect system which is not only a passive tool in human hands but rather an active partner equipped with a sort of artificial intelligence, having access to large information resources, being able to adapt its behavior to the human requirements and to collaborate with the human users. This book collects examples of recent human-computer system solutions. The content of the book is divided into three parts. Part I is devoted to detection, recognition and reasoning in different circumstances and applications. Problems associated with data modeling, acquisition and mining are presented by papers collected in part II and part III is devoted to Optimization.
Issues and Challenges in Science Education Research
by Mijung Kim Kim Chwee TanIn contemporary society, science constitutes a significant part of human life in that it impacts on how people experience and understand the world and themselves. The rapid advances in science and technology, newly established societal and cultural norms and values, and changes in the climate and environment, as well as, the depletion of natural resources all greatly impact the lives of children and youths, and hence their ways of learning, viewing the world, experiencing phenomena around them and interacting with others. These changes challenge science educators to rethink the epistemology and pedagogy in science classrooms today as the practice of science education needs to be proactive and relevant to students and prepare them for life in the present and in the future. Featuring contributions from highly experienced and celebrated science educators, as well as research perspectives from Europe, the USA, Asia and Australia, this book addresses theoretical and practical examples in science education that, on the one hand, plays a key role in our understanding of the world, and yet, paradoxically, now acknowledges a growing number of uncertainties of knowledge about the world. The material is in four sections that cover the learning and teaching of science from science literacy to multiple representations; science teacher education; the use of innovations and new technologies in science teaching and learning; and science learning in informal settings including outdoor environmental learning activities. Acknowledging the issues and challenges in science education, this book hopes to generate collaborative discussions among scholars, researchers, and educators to develop critical and creative ways of science teaching to improve and enrich the lives of our children and youths.

It Came from Something Awful: How a Toxic Troll Army Accidentally Memed Donald Trump into Office
by Dale BeranAn insider's history of the website at the end of the world, which burst into politics and memed Donald Trump into the White House.The internet has transformed the ways we think and act, and by consequence, our politics. The most impactful recent political movements on the far left and right started with massive online collectives of teenagers. Strangely, both movements began on the same website: an anime imageboard called 4chan.org. It Came from Something Awful is the fascinating and bizarre story of 4chan and its profound effect on youth counterculture.Dale Beran has observed the website's shifting activities and interests since the beginning. 4chan is a microcosm of the internet itself—simultaneously at the vanguard of contemporary culture, politics, comedy and language, and a new low for all of the above. It was the original meme machine, mostly frequented by socially awkward and disenfranchised young men in search of a place to be alone together.During the recession of the late 2000’s, the memes became political. 4chan was the online hub of a leftist hacker collective known as Anonymous and a prominent supporter of the Occupy Wall Street movement. But within a few short years, the site’s ideology spun on its axis; it became the birthplace and breeding ground of the alt-right. In It Came from Something Awful, Beran uses his insider’s knowledge and natural storytelling ability to chronicle 4chan's strange journey from creating rage-comics to inciting riots to—according to some—memeing Donald Trump into the White House.
