Distributed Power Control and Removal Algorithms for Multimedia CDMA Wireless Networks
Wang, Jui-Teng The Korea Institute of Information and Commucation 2003 Journal of communications and networks Vol.5 No.3
We study in this paper both distributed power control and removal algorithms for multimedia CDMA wireless networks. In our study, users can have different data rates as well as different quality of service (QoS) requirements. We derive a necessary and sufficient condition for the fully distributed power control (FDPC) algorithm to find a feasible power set. We also prove that, if the maximal power level is used at the start, then the distributed constrained power control (DCPC) algorithm is equivalent to the FDPC algorithm. For the connection removal algorithm, we prove that the non-reinitialized removal algorithm finds a feasible power set faster and employs smaller power levels than the reinitialized one does. Performances of some connection removal criteria are also studied. Our simulation results reveal that the smallest normalized CIR (SNC) and largest CIR requirement (LCR) criteria result in smaller outage probability than the smallest CIR (SC) criterion in a multimedia environment.

Objectives: Sacral insufficiency fracture (SIF) is not an uncommon osteoporosis fracture among the elderly. Aside from traditional treatments, sacroplasty and teriparatide (TPTD) injection have been introduced. This report aims to compare the effects of sacroplasty and teriparatide on clinical outcomes of SIF. Methods: Thirty-one elderly patients with SIF were enrolled in this retrospective observational study. Four male patients were excluded. Fourteen patients who received TPTD for 6 months were classified into the TPTD group (TT), and 13 who underwent sacroplasty were classified into the sacroplasty group (SS). All patients in both groups were instructed to take calcium and vitamin D supplements daily. Their symptoms and signs, visual analog score (VAS), Oswestry disability index (ODI), and radiographic studies were retrospectively reviewed. Results: The TT group showed significantly lower VAS than SS group after 3 (P < 0.001) and 6 months of treatment (P < 0.001). The TT group also has significant lower ODI than SS group after 1 (P = 0.010), 3 (P = 0.005) and 6 months (P < 0.001) of treatment. Upon generalized estimating equations (GEE) analysis, the TT group showed significantly more reduction in both VAS and ODI compared to the SS group at 1 month (P = 0.022, P = 0.001), 3 months (P < 0.001, P < 0.001), and 6 months (P < 0.001, P < 0.001) post-treatment. Conclusions: Postmenoposal woman with SIF who received TPTD healed better than those who underwent sacroplasty after 1 month treatment.

Osteoporosis and its associated fragility fractures are becoming a severe burden in the healthcare system globally. In the Asian-Pacific (AP) region, the rapidly increasing in aging population is the main reason accounting for the burden. Moreover, the paucity of quality care for osteoporosis continues to be an ongoing challenge. The Fracture Liaison Service (FLS) is a program promoted by International Osteoporosis Foundation (IOF) with a goal to improve quality of postfracture care and prevention of secondary fractures. In this review article, we would like to introduce the Taiwan FLS network. The first 2 programs were initiated in 2014 at the National Taiwan University Hospital and its affiliated Bei-Hu branch. Since then, the Taiwan FLS program has continued to grow exponentially. Through FLS workshops promoted by the Taiwanese Osteoporosis Association (TOA), program mentors have been able to share their valuable knowledge and clinical experience in order to promote establishments of additional programs. With 22 FLS sites including 11 successfully accredited on the best practice map, Taiwan remains as one of the highest FLS coverage countries in the AP region, and was also granted the IOF Best Secondary Fracture Prevention Promotion award in 2017. Despite challenges faced by the TOA, we strive to promote more FLS sites in Taiwan with a main goal of ameliorating further health burden in managing osteoporotic patients.
