Introduction: Delivering maximum dose to tumor and minimum dose to normal tissues is the most important goal in radiotherapy. According to ICRU, the maximum acceptable uncertainty in the delivered dose compared to the prescribed dose should be lower than 5%, and this is because of the relationship between absorbed dose, tumor control and normal tissue damage. Absorbed dose accuracy is investiga...

We report on the combination of slow light propagation with the resonanceproperties of a photonic crystal cavity and with the slow mode of a photonic crystalwaveguide.We demonstrate theoretically and experimentally that slow light induced by theCoherent Population Oscillation (CPO) effect enables to have small-size and ultra-high quality (Q) factor cavity, regardless of ...

Deformable 3D dosimeters have potential applications in validating deformable dose mapping algorithms. This study evaluates a novel deformable PRESAGE® dosimeter and its application toward validating the deformable algorithm employed by VelocityAI. The deformable PRESAGE® dosimeter exhibited a linear dose response with a sensitivity of 0.0032 ΔOD/(Gy/cm). Comparison of an experimental dosimeter...

The rapid melting of silicon film due to the absorption of a CW laser beam radiation is studied. The silicon film melting and recrystallization is mainly controlled by the temperature distribution in the semiconductor. The enthalpy technique for the solution of phase change problems is used in an explicit finite difference form to calculate the transient temperature distribution in the silicon ...

The hybrids of ATLAS semi-conductor tracker (SCT) were made with Cu/Polyimide flex-circuits, reinforced with carbon-carbon substrates, in the barrel and in the endcap modules. We report successes, problems and solutions in the course of production of 2600 pieces of hybrids each.

In the context of a semi-conductor based implementation of a quantum computer the idea of a quantum storage bit is presented and a possible implementation using a double quantum dot structure is considered. A measurement scheme using a stimulated Raman adiabatic passage is discussed.

An ideal conductor electrode in contact with a semi-infinite two-dimensional twocomponent plasma in an external potential is considered. The model is mapped onto an integrable sine-Gordon theory with Dirichlet boundary conditions. The information gained from the mapping provides an explicit form of the surface tension in the plasma-stability regime.
