Platelet‑rich plasma (PRP) is a promising strategy for intervertebral disc degeneration (IDD). However, the short half‑life of growth factors released from PRP cannot continuously stimulate the degenerated discs. Thus, the present study hypothesized that the combined use of PRP and bone marrow‑derived mesenchymal stem cells (BMSCs) may repair the early(More)
—In order to make full utilization of photovoltaic (PV) array output power, which depends on solar irradiation and ambient temperature, maximum power point tracking (MPPT) techniques are employed. Among all the MPPT strategies, the Perturb and Observe (P&O) algorithm is more attractive due to its simple control structure. Nevertheless, steady-state(More)
Predictive optimal control (POC) combined with artificial neural networks (ANNs) modeling and advanced heuristic optimization is a powerful technique for intelligent control. But actual implementation of the POC in complex industrial processes is limited by its known drawbacks, including the oscillation resulting from random search direction, difficulty in(More)
