Stereotactic MRI-guided Adaptive Radiation Therapy (SMART) for Locally Advanced Pancreatic Cancer: A Promising Approach. [PDF]
, 2018 Locally advanced pancreatic cancer (LAPC) is characterized by poor prognosis and low response durability with standard-of-care chemotherapy or chemoradiotherapy treatment.

Radiation hydrodynamics including irradiation and adaptive mesh refinement with AZEuS. I. Methods
, 2014 Aims. The importance of radiation to the physical structure of protoplanetary disks cannot be understated. However, protoplanetary disks evolve with time, and so to understand disk evolution and by association, disk structure, one should solve the ...

The Role of Legal Services in the Antipoverty Program [PDF]
, 1966 Large-scale adaptive radiations might explain the runaway success of a minority of extant vertebrate clades. This hypothesis predicts, among other things, rapid rates of morphological evolution during the early history of major groups, as lineages invade

Testing the adaptive radiation hypothesis for the lemurs of Madagascar [PDF]
Royal Society Open Science, 2017 Lemurs, the diverse, endemic primates of Madagascar, are thought to represent a classic example of adaptive radiation. Based on the most complete phylogeny of living and extinct lemurs yet assembled, I tested predictions of adaptive radiation theory by ...

Laser-controlled adaptive optic for beam quality enhancement in a multipass thin disk amplifier
, 2018 We devise a laser-controlled adaptive optical element which operates intracavity under high intensity radiation. This element substitutes a conventional mechanically deformable mirror and is free of critical heat-sensitive components and electronics. The

Rapid radiations underlie most of the known diversity of life
Frontiers in Ecology and EvolutionRapid radiations, including adaptive radiations, are of considerable interest to evolutionary biologists, in large part because they are thought to underlie much of the species diversity of life.

Comparative analyses for adaptive radiations [PDF]
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000 Biologists generally agree that most morphological variation between closely related species is adaptive. The most common method of comparative analysis to test for co–evolved character variation is based on a Brownian–motion model of character evolution.
