The title and abstract of the next Takuetsu seminar are as follows.

1.　Design, simulations, and experimental measurements of side-readout configurations for slab-based monolithic crystals used in PET detector modules

Presenter: Nguyen V.H. Viet (D3 student, RCNP Toyonaka)

Abstract: In positron emission tomography (PET), monolithic crystals have been used as an alternative to the conventional pixelated design to maintain high spatial resolution and improve energy/timing resolutions. Recent studies have proposed an approach using layers of thin crystal slabs with 4-side photosensor readout to address the challenges in thick monolithic crystals. In this work, I study how different crystal-sensor configurations of this approach affect the detector performance.

2. Molecular Chemical Analysis of Glycan-Biomolecule Interactions Using Synthetic Glycan Displaying System

Presenter：MIURA Ayane（D3, Dept. of Chemistry）

Abstract： Targeted alpha-ray therapy is one of the most effective cancer therapies. Our laboratory has shown that the dynamics of antibodies labeled with 211At, an alpha-ray emitting radionuclide, are important in enhancing their antitumor effects. In this study, I focus on the glycan-lectin interaction that regulates the dynamics of molecules on the cell membrane and analyze its mechanism in order to apply this interaction to α-ray-targeted therapy in the future.
