Primary pulmonary synovial sarcoma (PPSS) is an extremely rare intrathoracic soft tissue sarcoma, but there remains a notable absence of consensus guidelines for the diagnosis and treatment of these tumors. In this case, we reported a 35-year-old PPSS patient who received neoadjuvant chemotherapy co...

We propose a chaotic spatial symbol transforming encryption method for enhancing the physical layer security in fiber-optic systems based on space-division multiplexed (SDM) transmission. The designed 3-D chaotic sequences are used to scramble the real and imaginary part of quadrature amplitude modu...

Crop models serve as powerful tools for investigating the interaction of crop traits, environmental fluctuations, and management practices. However, the calibration of these models relies heavily on experiments conducted under specific conditions or within particular years. The adaptability and effi...
