Qi-Ju-Di-Huang-Pill delays the progression of diabetic retinopathy.

Ethnopharmacological Relevance: Qi-Ju-Di-Huang-Pill (QJDH pill) is a Chinese decoction. Although it is commonly used to treat eye conditions, such as diabetic retinopathy (DR), its exact mechanism of action is unknown.

Aim Of The Study: To investigate the specific mechanism by which QJDH pill slows the progression of diabetic retinopathy (DR) based on animal and cellular experiments.

Adaptive control of a switched hypersonic vehicle model robust to scramjet choking and elevator fault.

This paper studies the longitudinal control problem for air-breathing hypersonic vehicles (AHVs) with safety considerations on scramjet choking and elevator fault. A control-oriented switched model (COSM) is employed to better describe the full-envelope flight of AHVs. Unlike the recent control strategy that utilizes neural networks to approximate the unpredictable switching nonlinearities in the COSM, a control strategy free of neural networks is proposed for AHVs.
