Writing in London. Home and Languaging in the Work of London Poets of Chinese Descent

This essay discusses literary works produced in London by poets of Chinese descent who are foreign-born or London native. Some of these works are written in English, and some in Chinese. The aim is to discuss poetry that has emphatically or reluctantly embraced the identity narrative, talking of home and belonging in substantially different ways from each other, according to each poet’s individual relationship with movement, migration, and stability. Therefore, through the use of the phrase ‘London poets of Chinese descent’, I do not aim at tracing a shared sense of identity, but instead I am interested in using London as a method for an oblique reading that recognises the variety of angles and approaches in these poets’ individual experience, history and circumstances that can range from occasional travel to political exile

Theoretical and experimental study of the dark signal in CMOS image sensors affected by neutron radiation from a nuclear reactor

The CMOS image sensors (CISs) are irradiated with neutron from a nuclear reactor. The dark signal in CISs affected by neutron radiation is studied theoretically and experimentally. The Primary knock-on atoms (PKA) energy spectra for 1 MeV incident neutrons are simulated by Geant4. And the theoretical models for the mean dark signal, dark signal non-uniformity (DSNU) and dark signal distribution versus neutron fluence are established. The results are found to be in good agreement with the experimental outputs. Finally, the dark signal in the CISs under the different neutron fluence conditions is estimated. This study provides the theoretical and experimental evidence for the displacement damage effects on the dark signal CISs

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

THE CHINESE PRACTICE‐ORIENTED VIEWS OF SCIENCE AND THEIR POLITICAL GROUNDS

In China, practice-oriented views of science can be traced back to antiquity. In ancient times, the Chinese people independently created and developed application-oriented sciences, but they ignored basic science. In modern times, China learned and introduced Western science and technology as a practical instrument to protect the nation and make it prosperous and powerful. Through technology and production, science has been playing an immediate and major role in the development of socialism since 1949. Since 1978, the Chinese government has always emphasized that science and technology are the primary productive forces. From ancient times to the present, the practice-oriented views of science are grounded in politics. Science has been the handmaiden of politics since the Qin Dynasty. However, this state of affairs hinders the development of basic science, a science that is not oriented toward immediate application. It also hinders open-minded, critical reflection on the downsides or limits of science, which could draw on broader (moral, spiritual, or religious) values
