Background: Boron neutron capture therapy (BNCT) is a binary radiotherapy combining biochemical targeting with neutron irradiation. However, monitoring the boron distribution is a fundamental problem in BNCT. Prompt gamma rays emitted by boron capture reaction can be used to address the issue. Materials and Methods: The general-purpose Monte Carlo toolkits Geant4 and MCNP were used for the simu...

Several works have proven that finetuning is an applicable approach for debiasing contextualized word embeddings. Similarly, discrete prompts with semantic meanings shown to be effective in tasks. With unfixed mathematical representation at the token level, continuous usually surpass ones providing a pre-trained language model (PLM) additional task-specific information. Despite this, relatively...

objective: the use of presently available dentin bonding systems has greatly reduced mi-croleakage; however, the ideal situation where the adhesive resin completely penetrates the demineralized dentin is not yet achieved. the purpose was to compare the microleak-age of fifth and sixth generation bonding agents at enamel and dentinal margins. materials and methods: class v cavities were prepared...

Abstract As a gamma-ray burst (GRB) jet drills its way through the collapsing star, it traps baryonic “cork” ahead of it. Here we explore prompt emission model for GRBs in which does not cross cork, but rather photons that are emitted deep flow largely by pair annihilation scattered inside expanding cork and escape from back end as they push behind. Due to relativistic motion these easily seen ...
