We present an alternative scheme to achieve nonreciprocal unconventional magnon blockade (NUMB) in a hybrid system formed by two microwave cavities and one yttrium iron garnet (YIG) sphere, where the pump and signal cavities interact nonlinearly with each other and the signal cavity is coupled to the YIG sphere. It is found that the nonlinear coupling occurs between the pump cavity and magnon modes due to the dispersive interactions among three bosonic modes. Meanwhile, the Kerr nonlinearity is present in the pump cavity.

Background: Reducing postoperative pain immediately after surgery is crucial because severe postoperative pain reduces quality of life and increases the likelihood that patients develop chronic pain. Even though postoperative pain has been widely studied and there are national guidelines for pain management, the postoperative course is differently from one patient to the next. Different postoperative courses could be explained by factors related to the treatment context and the patients.

A 58-year-old male patient diagnosed with thromboangiitis obliterans (Fontaine stage IV) was recently treated with microendoscope discectomy system-assisted spinal cord stimulation electrode implantation and cured by department of vascular surgery combined with department of spinal surgery at Peking University People's Hospital. The patient suffered from cold injury to the right foot 14 years ago, which was cold, painful, numb, and then the toe was ulcerated and gangrene. Only the right foot small toe was left.
