Biologically adapted radiation therapy
Zeitschrift für Medizinische Physik, 2018 The aim of biologically adapted radiotherapy (RT) is to shape or paint the prescribed radiation dose according to biological properties of the tumor in order to increase local control rates in the future. Human tumors are known to present with an extremely heterogeneous tissue architecture leading to highly variable local cell densities and chaotic ...

Advanced Engineering Materials, EarlyView.This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

Impact of the terrestrial-aquatic transition on disparity and rates of evolution in the carnivoran skull. [PDF]
, 2015 Which factors influence the distribution patterns of morphological diversity among clades? The adaptive radiation model predicts that a clade entering new ecological niche will experience high rates of evolution early in its history, followed by a ...

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
Advanced Engineering Materials, EarlyView.This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Quaternary Radiation of Spring Ephemerals
Plant-Environment InteractionsThe emergence of East Asian spring ephemerals and the unique ecosystem can be attributed primarily to vicariance, brought about by the Quaternary rifting of the Okinawa Trough, the formation of the East China Sea, and the isolation of the island chains ...

Phylogenetic Insights on Adaptive Radiation
, 2010 Adaptive radiation is a response to natural selection and ecological opportunity involving diversification of species and associated adaptations. Although evolutionary biologists have long speculated that adaptive radiation is responsible for most of ...

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

, 2007 Adaptive responses are induced by stress such as X radiation and result in a lower than expected biological response. Two-dose adaptive response experiments typically involve a low priming dose followed by a subsequent high radiation dose.
