RE-IRRADIATION OF NTRACRANIAL TUMORS WITH ACTIVE BEAM SCANNING PROTONS

Сибирский онкологический журнал, 2017
Recently, there has been a growing interest in the use of active beam scanning proton therapy for re-irradiation of CNS tumors. Although this treatment option for recurrent intracranial tumors is considered effective, however, it is rarely used because ...

Dissolution Study of Biodegradable Magnesium Silicide Thin Films for Transient Electronic Applications

Advanced Science, EarlyView.
Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...

Renormalization of radiobiological response functions by energy loss fluctuations and complexities in chromosome aberration induction: deactivation theory for proton therapy from cells to tumor control

, 2019
We employ a multi-scale mechanistic approach to investigate radiation induced cell toxicities and deactivation mechanisms as a function of linear energy transfer in hadron therapy.

Photon‐to‐Heat Energy Harvesting Fluorescent Protein Coatings for Thermoelectrics

Advanced Science, EarlyView.
Fluorescent proteins (FPs) are used in light‐absorbing coatings on thermoelectric generators (TEGs) to convert light into heat and generate electricity. By tuning the properties of FP‐doped polymer matrices, photothermal efficiencies of up to 48% have been achieved.

Foundation of an analytical proton beamlet model for inclusion in a general proton dose calculation system

, 2010
We have developed a model for proton depth dose and lateral distributions based on Monte Carlo calculations (GEANT4) and an integration procedure of the Bethe-Bloch equation (BBE).

The scenario-based generalization of radiation therapy margins

, 2015
We give a scenario-based treatment plan optimization formulation that is equivalent to planning with geometric margins if the scenario doses are calculated using the static dose cloud approximation.
