The proposed procedure is based on the condi- tional characteristic function, and the maximum empirical likelihood estimator is proved to be consistent and asymptotically normal. Moreover, this estimator is shown to be asymptotically efficient under some mild conditions. When the background driving Lévy process is of type A or B, we show that the intensity parameter can be exactly recovered, and we study the maximum empirical likelihood estimator with the plug-in estimated intensity parameter. Testing procedures based on the empirical likelihood ratio statistic are developed for parameters and for estimating equations, respectively. Finally, Monte Carlo simulations are conducted to demonstrate the performance of proposed estimators.展开更多

This result was given by Csrg and Revesz （1981）, but the proof gets them nowhere. We also gave a similar local continuity modulus result for the infinite dimensional OU processes.展开更多

In this survey paper, we focus on G/GI/n ＋ GI parallel-server queues that serve as a building block to model call center operations. Such a queue has a general arrival process （the G ）, independent and identically distributed （iid） service times with a general distribution （the first G1 ）, and iid patience times with a general distribution （the ＋GI）. Following the square-root safety staffing rule, this queue can be operated in the quality- and efficiency-driven （QED） regime, which is characterized by large customer volume, the waiting times being a fraction of the service times, only a small fraction of customers abandoning the system, and high server utilization. Operational efficiency is the central target in a system whose staffing costs dominate other expenses. If a moderate fraction of customer abandonment is allowed, such a system should be operated in an overloaded regime known as the efficiency-driven （ED） regime. We survey recent results on the many-server queues that are operated in the QED and ED regimes. These results include the performance insensitivity to patience time distributions and diffusion and fluid approximate models as practical tools for performance analysis.展开更多

Two front-end observations showed that placement of the contralateral hand on the acute abdomen of women alleviated pain (78 of 81 women or 96.3%), while placement of the ipsilateral hand did not (0 of 39 women or 0%). This method named as Ou MC handing remedy (HR) was used to observe the immediate and cumulative effects of OuDP on 38 cases, of which 27 were self-administered and 11 were administered by the therapist. The mean age of the patients was 55.8 years (standard deviation, 22.9 years). Five minutes after initial self-administered HR, there was pain alleviation in 14 cases and symptoms or signs beyond pain improved for another 6 cases while 7 cases unevaluated. Final results showed 9 cured, 5 with partial remission and the remaining 13 with complete remission. Five minutes after initial therapist-administered HR, pain alleviation was found with 10 cases while 1 case unevaluated. The final results showed 7 cases cured, 2 with partial remission, and 2 with complete remission. The resolution of non-infectious conditions (23/ 38) with OuDP is consistent with the restoration of normal tissue function, which seems to contribute to pain alleviation and defense against infections and tumors. Interestingly, the OuDP is capable of being invoked by either the patient or the therapist. These findings warrant further investigation.展开更多

In this paper, it is analyzed from a memetics perspective that regards"Chen Ou Style"as a strong meme. The purpose is to find out the internal generating mechanism for a meme to become successful, to reveal the evolution process of language, and to provide some useful guidelines and references for better language use. It is concluded that the replication and transmission of"Chen Ou Style"indicates the existence of language memes, and memetics provides a new perspective for the analysis of language imitation, transmission, change and development.展开更多

The resolution of non-infectious conditions with OuDP indicates to be consistent with restoration of normal tissue function (AJEM, 2012;Proc Physiol Soc, 2014). Ou MC handing remedy (HR) was utilized to induce OuDP by applying the hand to the contralateral body. Four female patients received self-administered HR separately for their diseases: 1) uterine endometrioid carcinoma stage IIIB, 2) suspicious pancreatic cancer in stage IA with isodense pancreatic nodule, elevated CA199 and dilated tortuous main pancreatic duct, 3) uterine leiomyosarcoma stage IB, and 4) suspicious gluteal metastatic lesion of chronic myelogenous leukemia. The treatments with HR showed to suppress or ameliorate oncologic changes for these patients: 1) The uterine endometrioid carcinoma regressed from stage IIIB to IA with 5 months treatment. 2) The pancreatic isodense lesion decreased from 1.6 × 1.7 to 1.0 × 1.0 cm in size with CA199 descending from 1090.0 to 136.5 (Unit/ml) associating with the main pancreatic duct diameter decreasing from 0.39 to 0.14 cm with tortuosity disappearance after 4 months treatment. 3) The frequent profuse bleeding by uterine leiomyosarcoma prominently decreased immediately with HR and subsequent HR was also effective at minimizing heavy uterine bleeding in the 3 weeks treatment. 4) The gluteal macular lesion of the case with chronic myelogenous leukemia was eliminated with 2 weeks treatment. It reveals OuDP may normalize the tumor cells and microenvironment function, which makes tumor cells conform to the *Corresponding author. regulations with apoptosis, metastasis suppression, preventing uninhibited proliferation, minimizing angiogenesis and supervision by host immunological systems.
