INTRODUCTION Ankylosing spondylitis (AS) is a chronic autoimmune disease, and the precise pathogenesis is largely unknown at present. Bone marrow-derived mesenchymal stem cells (BMSCs) with immunosuppressive and anti-inflammatory potential and Th17/Treg cells with a reciprocal relationship regulated by BMSCs have been reported to be involved in some(More)
Avascular necrosis of femoral head (ANFH) is a progressive disease that often leads to hip joint dysfunction and even disability in young patients. Although the standard treatment, which is core decompression, has the advantage of minimal invasion, the efficacy is variable. Recent studies have shown that implantation of bone marrow containing osteogenic(More)
—Previous Probe Gap Model (PGM) based available bandwidth (AB) estimation methods all request the " busy assumption " that probing packet pairs should be in the same busy period when transmitted on bottleneck link, which is hard to satisfy especially for the low utilization path. In this paper, we first present a new probabilistic methodology to estimate AB(More)
RSVP is basically designed for fixed networks and does not provide mobility support. In order to provide QoS support for mobility in a wireless environment, we present a new resource reservation protocol for seamless handover. HO-RSVP integrates with Mobile IPv4 to maintain a continuous QoS guarantee between two mobile nodes. In the protocol, the resource(More)
OVERVIEW: Telecommunication systems play a very important role in the infrastructure of smart cities. A plethora of networked devices interact to provide safe, convenient and environmentally conscious new services. Residents in smart cities can enjoy their lives using these services, seamlessly and without being aware of the existence of the networks. To(More)
In various Internet of Things (IoT) application scenarios, such as environment monitoring, smart city, etc., most of them are restricted in distribution because of the resource constrained issue over most typical IoT devices. The limitation of devices hardware performance further involves the issue of weak transferring and processing of huge data. A(More)
