Acupuncture has been applied in the clinic to treat visceral pain for a long time. However, the underlying mechanism still remains unknown. In the present study, extrasegmental analgesia of electroacupuncture (EA) at orofacial acupoints on visceral pain rats was investigated. The results revealed that nociceptive EA stimulation applied at heterotopic(More)
This paper investigates the power allocation scheme to maximize the sum-rate of a two-way full-duplex (FD) AF relay system under residual self-interference. The variance of self-interference is proportional to the λth power of transmitted power (λ denotes the self-interference level and 0 ≤ λ ≤ 1). The optimization problem(More)
A reversible watermarking algorithm is presented, which achieves content authentication and perfect restoration of the original image during extraction. The proposed algorithm is based on patchwork and chaotic encryption. The patchwork algorithm is used to generate zero-bit watermark for content authentication. The chaotic sequence is used to encrypt the(More)
Helicobacter pylori (H. pylori) is a life-threatening pathogen which causes chronic gastritis, gastric ulcers and even stomach cancer. Treatment normally involves bacterial eradication; however, this type of treatment only has a rate of effectiveness of <80%. Thus, it is a matter of some urgency to develop new therapeutic strategies. Lactoferrin, a member(More)
In this paper, we investigate the energy-efficiency (EE) of a user equipment (UE) experiencing the worst channel conditions, which is named worst-EE. Due to the limitation on the capacity of the mobile equipments' battery, the worst-EE is suitable for EE fairness optimization in the uplink transmissions of orthogonal frequency division multiple access(More)
