Medical ethics is closely intertwined with culture, and the development of Chinese medical ethics cannot be separated from the concerns of Chinese culture. The internationally popular principlism theory contains misconceptions because it overemphasizes regulative principles while neglecting constitu...

Living organ transplantation requires ethical reflection on the relational dynamics embedded behind the flow of organs. In the Confucian concept of gift-giving, living organs are regarded as ritual gifts rather than mere objects, reflecting the ethical tangibility and productive nature of transplant...

A new channel estimation method is proposed based on fast orthogonal frequency-division multiplexing (FOFDM), which can be effectively used in our experiment based on intensity modulation and direct detection. In this experiment, the FOFDM subcarrier channel spacing is half of the symbol rate. The s...

In this paper, an overlap frequency-domain equalization (OFDE) scheme is proposed and experimentally demonstrated in an intensity modulation and direct-detection optical communication system with carrierless amplitude and phase (CAP) modulation. Moreover, the negative chirp property of the Mach&...

In this paper, a real-time hybrid fiber and visible laser light communication orthogonal frequency division multiplexing (OFDM) transport system is experimentally demonstrated. Based on virtual input&#x002F;output technique, the system can be configured dynamically by using software. Although th...

In this paper, a simple and overhead-free sampling frequency offset (SFO) blind estimation and compensation scheme is proposed and experimentally demonstrated in a short-reach direct detection orthogonal frequency division multiplexing (DD-OFDM) transmission system. After extracting subcarriers of O...

BackgroundGastric cancer (GC) poses a significant threat to human health. Despite considerable advancements in immunotherapy for GC, the effectiveness of current immunotherapeutic targets remains constrained by the heterogeneity of the tumor microenvironment and mechanisms of immune evasion. Consequ...

Extreme low-temperature incidents have become more frequent and severe as climate change intensifies. In Huang-Huai-Hai wheat growing area of China, the late spring coldness occurring at the jointing-booting stage (the anther interval stage) has resulted in significant yield losses of winter wheat....
