In this paper, we introduce surface plenoptic function (SPF) as a tool for the sampling analysis of image-based rendering (IBR). SPF is a plenoptic function defined on the object surface. It can be mapped onto the normal IBR representation via a coordinate transform. By assuming some properties of the SPF, we can provide insightful analysis on the sampling of the IBR representation, for both un...

A significant survival difference between black and white breast cancer patients has been observed in the United States. Evaluation of the prognostic value of DNA ploidy and S-phase fraction (SPF) in black and white breast cancer patients may contribute to our understanding of the mechanisms of racial disparity in survival. A sample of 98 patients (50 blacks and 48 whites) who participated in t...

STUDY DESIGN Systematic review. OBJECTIVE To identify and describe reconstruction methods for the treatment of transverse sacral fracture (TSF) and to evaluate outcomes based on treatment interventions. SUMMARY OF BACKGROUND DATA A variety of surgical interventions for stabilization of TSFs exist, yet the optimal management remains unclear. Although there are many individual case reports an...

Long exposure of UV radiation increases risk of skin diseases such as cancer and photoallergic reactions. UV-B (280-320 nm) radiation is mainly responsible for inducing skin problems. Skin protection is a suitable method in the fight against ultraviolet radiation induced damage. Various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they h...

Subarachnoid pleural fistula (SPF) following injury to the vertebral column is an extremely rare complication and is usually described after blunt trauma. We report the first case of SPF with pneumocephalus due to a gunshot wound to the spine.

Sex pheromones form an important facet of reproductive strategies in many organisms throughout the Animal Kingdom. One of the oldest known sex pheromones in vertebrates are proteins of the Sodefrin Precursor-like Factor (SPF) system, which already had a courtship function in early salamanders. The subsequent evolution of salamanders is characterized by a diversification in courtship and reprodu...

Long exposure of UV radiation increases risk of skin diseases such as cancer and photoallergic reactions. UV-B (280-320 nm) radiation is mainly responsible for inducing the skin problems. Skin protection is a suitable method against ultraviolet radiation-induced damage. Various synthetic agents have been used as photo protective but because of their potential toxicity in humans, they have limit...

Image-based rendering (IBR) has become a very active research area in recent years. The spectral analysis problem for IBR has not been completely solved. In this paper, we present a new method to parameterize the problem, which is applicable for general-purpose IBR spectral analysis. We notice that any plenoptic function is generated by light ray emitted/reflected/refracted from the object surf...

Commensal bacteria control the micro-ecology of metazoan epithelial surfaces with pivotal effect on tissue homeostasis and host defense. In contrast to the upper respiratory tract, the lower respiratory tract of healthy individuals has largely been considered free of microorganisms. To understand airway micro-ecology we studied microbiota of sterilely excised lungs from mice of different origin...

Zusammenfassung Schülerinnen und Schüler mit sonderpädagogischem Förderbedarf (SPF) werden in Deutschland an Förderschulen inklusiv allgemeinen Schulen unterrichtet. Ein Ziel dieser inklusiven Beschulung ist eine bessere soziale Integration der SPF Gesellschaft. Inwiefern diese im Schulalltag sozial integriert sind, wird bisher wenig thematisiert. Dieser Beitrag untersucht, ob wie sich die durc...
