Light and Skin Interactions immerses you in one of the most fascinating application areas of computer graphics: appearance simulation. The book first illuminates the fundamental biophysical processes that affect skin appearance, and reviews seminal related works aimed at applications in life and health sciences. It then examines four exemplary modeling approaches as well as definitive algorithms that can be used to generate realistic images depicting skin appearance. Despite its wide scope of simulation approaches, the book's content is presented in a concise manner, focusing on relevant practical aspects. What's more, these approaches can be successfully applied to a wide range of additional materials, such as eye tissue, hair, and water. - Allows you to understand and predict the qualitative and quantitative behavior of complex natural systems - A general background on tissue optics clarifies several confusing conceptual issues, saving you valuable time in the early stages of research - Includes complete code and data sources for the BioSpec model

Light-based therapies have been a major component of dermatologic practice. Historically, these treatment modalities have been mainly tailored to the treatment of patients with light skin. Principles governing use of light therapies in skin of color are less defined. However, there is a tremendous need to understand the benefits and limitations of these therapeutic options for dark-skinned patients as well. Demographic data in the United States alone indicate that the population and recipients of health care are rapidly changing with regard to skin phototype. Physicians who are involved in the delivery of care for patients with cutaneous problems that can be addressed by light treatments need to be able to fully understand the mechanisms, applications, risks, efficacy, adverse events, and other pertinent issues in considering treatment options for their patients with pigmented skin.

Employing survey archaeology, excavation, ethnographic study, and multinational archival work, the Shala Valley Project uncovered the many powerful, creative ways whereby the men and women of Shala shaped their world: through dynamic, world-systemic relationships with the powers that surrounded but never fully conquered them. The Shala Valley Project presents the highlanders, the malesore, in the full complexity of their lives, while also unveiling a new, deeper history for the region--a history that reaches back to an unexpected fortified Iron Age site. Light and Shadow tells many stories. Archaeologists, historians, and students of tribes, of empires, of imperial-indigenous relations, of blood feud, of kinship, of the built landscape, of world-systems theory and sustainability science, and more, will find much here to digest. The people of Shala, to which Light and Shadow is dedicated, may serve as an example in our modern age, one in which persistent, tribal peoples still fight for their survival, and seek to preserve some degree of independence from capitalist economies bent on their incorporation.
