The sequential estimation （SE） algorithm has a poor performance in the environment with a low signalto-noise ratio （SNR） and a high bit error rate （BER）, especially for unknown initial acquisition sequence. This paper summarizes the conventional sequence acquisition model, and discovers its several problems, which are caused by accumulating sequence innovation to all of the received sequences dispersedly. To solve these problems, the paper presents a new algorithm, CSAS-SA （controllable single accumulated state-sequential acquisition）. This algorithm accumulates the sequence innovation to a single appointed sequence state and makes the useful information accumulated effectively. Through simulation, CSAS-SA has a higher probability of success acquisition. When SNR equals -3 dB, the performance can be improved by 70%.

Three(2+1)-dimensional equations–KP equation, cylindrical KP equation and spherical KP equation, have been reduced to the same Kd V equation by different transformation of variables respectively. Since the single solitary wave solution and 2-solitary wave solution of the Kd V equation have been known already, substituting the solutions of the Kd V equation into the corresponding transformation of variables respectively, the single and 2-solitary wave solutions of the three(2+1)-dimensional equations can be obtained successfully.

AIM To explore the effects of omeprazole on chemoradiotherapy efficacy and tumor recurrence in rectal cancer. METHODS The medical data of 125 rectal cancer patients who received the same neoadjuvant chemoradiotherapy(CRT) followed by surgery were retrospectively collected. Patients who received omeprazole(OME) orally at a dose of 20 mg at least once daily for six days and/or intravenously at 40 mg a day were recognized as eligible OME users(EOU). Otherwise, patients were regarded as non-eligible OME users(non-EOU).Moreover, a preferred OME dose cut-off of 200 mg on tumor recurrence was obtained by receiver operating characteristic(ROC) curves. Patients were divided into two groups: the effective OME group(EOG, OME ≥ 200 mg) and the non-effective OME group(non-EOG, OME < 200 mg). RESULTS The good response rate of CRT efficacy(50.8%) in EOU was significantly increased compared with nonEOU(30.6%)(P = 0.02). The recurrence rate in the EOG was 10.3%, which was significantly lower compared with 31.3% in non-EOG(P = 0.025). The good response rate of CRT efficacy in EOG was 55.2%, which was obviously higher compared with 36.5% in non-EOG, with a significant difference(P = 0.072). Multivariate Cox analysis demonstrated that OME(nonEOG and EOG) was an independent and significant impact factor for DFS(P = 0.048, HR = 0.30, 95%CI: 0.09-0.99).CONCLUSION When applied as an adjuvant drug in cancer treatment for relieving common side effects of chemotherapy, omeprazole has a synergetic effect in improving CRT efficacy and decreasing rectal cancer recurrence.
