Purpose: The accuracy and convergence behavior of a variant of the Demons deformable registration algorithm were investigated for use in cone-beam CT (CBCT)-guided procedures of the head and neck. Online use of deformable registration for guidance of

Summary Technological advances have made it possible for tumoricidal doses of radiation to be delivered to primary and metastatic liver cancers. Computed tomography, magnetic resonance imaging, ultrasound and positron emission tomography are used to

The extended logistic model relates seasonal dry matter and plant nutrient uptake to applied nutrient level. It has been shown to apply to data for annuals such as corn (Zea mays L.) and perennials such as bermudagrass (Cynodon dactylon L.) and bahia

The extended multiple logistic model has been used to describe seasonal dry matter and plant nutrient uptake in response to combinations of applied nitrogen (N), phosphorus (P), and potassium (K) for bermudagrass (Cynodon dactylon L) and tall fescue

Forage production is influenced by such factors as applied nutrients, water availability, and harvest interval (for perennials). Logistic models have been developed for response to single and multiple elements such as nitrogen (N), phosphorus (P), an

Crop production depends upon many factors such as level of applied nutrients, available water, stage of growth, crop species, soil type, and harvest interval (for perennials). Mathematical models provide a framework for linking these factors in a qua

The extended logistic model utilizes relatively simple analytical functions for coupling seasonal accumulation of dry matter and plant nutrient uptake to applied nutrient level. In this article model parameters are evaluated for response of Coastal b

An expanded growth model for annual and perennial agricultural crops has been developed. Data from several field studies with corn (Zea mays L.) have been analyzed to provide support for the model. Other studies with the perennials bermudagrass (Cyno
