This accessible, informative and entertaining, book provides the detail and substance that will reward the serious naturalist or the amateur diver

The book Theory and Practice of Contrast completes, corrects and integrates the foundations of science and humanities, which include: theory of art, philosophy (aesthetics, epistemology, ontology, axiology), cognitive science, theory of information, theory of complexity and physics. Through the integration of these distant disciplines, many unresolved issues in contemporary science have been clarified or better understood, among others: defining impact (contrast) and using this definition in different fields of knowledge; understanding what beauty/art is and what our aesthetic preferences depend on; deeper understanding of what complexity and information are in essence, and providing their general definitions. Complexity means integration, value and goodness - concepts that seem to be neglected today. The book also has a high degree of integration/complexity, although each chapter introduces a new issue. The last chapter: "Binary Model of the Universe" draws attention to the need for including in physics the analysis of our mind and the resulting new possibilities, which include the mentioned (digital) model of the universe. Despite the difficult issues raised here, this study is written in accessible language and may be interesting not only for scientists and academics.

Examines in detail the different clinical applications of microbubble-based contrast agents. Explains the principles underlying the use of contrast-specific imaging techniques and the examination methodology. Contains numerous high-quality illustrations, including many in color. Written by recognized experts.

In 1967, the Supreme Court legalized interracial marriage in America. Devin Hughes was born two years later to a black father and white mother who fled to Washington DC to escape the racism of the Deep South. Bigotry still ran rampant up North, and light-skinned, greeneyed Devin felt its pull from both ends: strangers who didn't know he was half-black and friends who didn't care he was half-white. In racial limbo, Devin found himself more consumed with his dysfunctional family life-a father who offered an alternative "street" education and a mother whose drug use zombified her for most of his childhood. Despite his parents' flaws, they were Devin's greatest believers. From his dad founding a neighborhood baseball team to his mom advocating for him in school, they taught Devin that anything imaginable was within reach, that their mistakes needn't be his choices, and that his destiny was for greatness. Ultimately, Contrast: A Biracial Man's Journey to Desegregate His Past isn't a book about race; it's a book about acceptance, perseverance, and love.

Generalized Phase Contrast elevates the phase contrast technique not only to improve phase imaging but also to cross over and interface with diverse and seemingly disparate fields of contemporary optics and photonics. This book presents a comprehensive introduction to the Generalized Phase Contrast (GPC) method including an overview of the range of current and potential applications of GPC in wavefront sensing and phase imaging, structured laser illumination and image projection, optical trapping and manipulation, and optical encryption and decryption. The GPC method goes further than the restrictive assumptions of conventional Zernike phase contrast analysis and achieves an expanded range of validity beyond weak phase perturbations. The generalized analysis yields design criteria for tuning experimental parameters to achieve optimal performance in terms of accuracy, fidelity and light efficiency. Optimization can address practical issues, such as finding an optimal spatial filter for the chosen application, and can even enable a Reverse Phase Contrast mode where intensity patterns are converted into a phase modulation.
