Proton Radiation Effects on Dark Signal Distribution of PPD CMOS Image Sensors: Both TID and DDD Effects.

Four-transistor (T) pinned photodiode (PPD) CMOS image sensors (CISs) with four-megapixel resolution using 11µm pitch high dynamic range pixel were radiated with 3 MeV and 10MeV protons. The dark signal was measured pre- and post-radiation, with the dark signal post irradiation showing a remarkable increase. A theoretical method of dark signal distribution pre- and post-radiation is used to analyze the degradation mechanisms of the dark signal distribution. The theoretical results are in good agreement with experimental results. This research would provide a good understanding of the proton radiation effects on the CIS and make it possible to predict the dark signal distribution of the CIS under the complex proton radiation environments.

[Herbalism and germplasm of deltaleaf goldthread rhizome].

Through textual research of herbalism about Chinese Goldthread Rhizome in different periods of ancients and some modern study, and analysis on correlativity between its name and different germplasm, it showed that the knowledge level of quality of the medicinal materials was gradually increased in its historical record of application by the society improvement and increasing of requirements and population from producing area, diversity of character to germplasm resources. The materials name of Chinese Goldthread Rhizome was from unitary to diversity and referred to the rhizomes of all plants of Coptis in China, while Deltaleaf Goldthread Rhizome took an important role in the evolution of Chinese Goldthread Rhizome. The aim of the work was to provide a reference for the correlative study of phylogeny, individual distribution, ecological environment and medical resources.
