Adaptive radiation therapy [PDF]
Physics in Medicine and Biology, 1997 Adaptive radiation therapy is a closed-loop radiation treatment process where the treatment plan can be modified using a systematic feedback of measurements. Adaptive radiation therapy intends to improve radiation treatment by systematically monitoring treatment variations and incorporating them to re-optimize the treatment plan early on during the ...

Pangenomes as a framework for adaptive radiation, speciation, and adaptation. [PDF]
Am J BotAbstract Understanding the genomic basis of diversification is a central goal in evolutionary biology. In recent years, the development and use of pangenomes, a genomic representation of multiple individuals within a lineage (a set of related populations, subspecies, ecotypes, or species), has enabled researchers to differentiate ...

Ecology and Evolution, 2021 Biological populations may survive lethal environmental stress through evolutionary rescue. The rescued populations typically suffer a reduction in growth performance and harbor very low genetic diversity compared with their parental populations.

Three-dimensional adaptive evolution of gravitational waves in numerical relativity [PDF]
, 2000 Adaptive techniques are crucial for successful numerical modeling of gravitational waves from astrophysical sources such as coalescing compact binaries, since the radiation typically has wavelengths much larger than the scale of the sources.

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

Dendrite fragmentation induced by massive-like δ–γ transformation in Fe–C alloys
Nature Communications, 2019 Transitioning from columnar to equiaxed grains is paramount for desired microstructures during steel casting. Here, the authors report a new fragmentation mechanism based on a phase transition at grain boundaries that can contribute to equiaxed grains.

The Role of Photobionts as Drivers of Diversification in an Island Radiation of Lichen-Forming Fungi
Frontiers in Microbiology, 2022 Speciation in oceanic islands has attracted the interest of scientists since the 19th century. One of the most striking evolutionary phenomena that can be studied in islands is adaptive radiation, that is, when a lineage gives rise to different species ...

Molecular Adaptation during a Rapid Adaptive Radiation [PDF]
Molecular Biology and Evolution, 2013 "Explosive" adaptive radiations on islands remain one of the most puzzling evolutionary phenomena and the evolutionary genetic processes behind such radiations remain unclear. Rapid morphological and ecological evolution during island radiations suggests that many genes may be under fairly strong selection, although this remains untested.
