In Multiple-Input Multiple-Out （MIMO） systems, the user selection algorithm plays an important role in the realization of multiplexing gain. In this paper, an improved Semi-orthogonal User Selection algorithm based on condition number is proposed. Besides, a new MIMO pre- coding scheme is designed. The proposed SUS- CN （SUS with condition number） algorithm outperforms the SUS algorithm for the selection of users with better matrix inversion property, thus a higher information rate for selected user pair is achieved. The designed MIMO precoding matrix brings benefits of the power equality at transmitted terminals, the limited dynamic range of the power over time, and a better power efficiency. The simulation results give the key insights into the im- pact of the different condition number value and users on the sum-rate capacity.

A cross-association model was proposed for CO2-alcohol mixtures based on the statistical associating fluid theory (SAFT).CO2 was treated as a pseudo-associating molecule and both the self-association between alcohol hydroxyls and the cross-association between CO2 and alcohol hydroxyls were *** equilibrium properties from low temperature-pressure to high temperature-pressure were investigated using this *** calculated p-x and p-p diagrams of CO2-methanol and CO2-ethanol mixtures agreed with the experimental *** results showed that when the cross-association was taken into account for Helmholtz free energy,the calculated equilibrium properties could be significantly improved,and the error prediction of the three phase equilibria and triple points in low temperature regions could be avoided.

OBJECTIVE To evaluate the clinical effectivity and toxicity of the regimen FMD （fludarabine, mitoxantrone, dexamethasone） in patients with non-Hodgkin＇s lymphoma. METHODS Thirty-two patients, twenty-four of whom had indolent B-cell lymphoma, 6 peripheral T-cell lymphoma, two diffuse large B-cell lymphoma, received FMD. Treatment comprised： fludarabine 25-30 mg/m^2 days 1-3, mitoxantrone 8-10 mg/m^2 day 1, and dexamethasone 20-30 mg/m^2 days 1-5. At the same time, patients received prophylaxis against conditional infection with trimethoprim-sulfamethoxazole, fluconazole, acyclovir and immunoglobulin. RESULTS Of the thirty-two patients treated, the complete response （CR） rate, partial response （PR） rate and overall response （OR） rate were 56.3%, 21.9% and 78.2% respectively. The CR and OR rate of 24 patients with indolent B-cell lymphoma were 66.7% and 88.3% respectively. Two of six patients with peripheral T-cell lymphoma were of complete response type and one was of partial response type. One of two patients with diffuse large B-cell lymphoma was partial response. The dominating toxicity was myelotoxicity and immunotoxicity. There was no treatment associated death in all patients treated with FMD. Grade 3-4 neutropenia occurred in 43.8% patients, 12.5% patients had infections and 9.3% developed grade 3-4 thrombocytopenia. At a median follow-up of 24 （5-54） months, the 2-year overall-survival rate and progression-free survival rate were （87.5 ± 1.4）% and （83.3 ± 1.6）% respectively. The 2-year OS and PFS rates of the indolent group were （93.75 ± 6.25）% and （87.5 ± 8.54）%. CONCluSION FMD regimen was highly effective with low toxicity in the treatment of non-Hodgkin＇s lymphoma, especially in indolent B-cell lymphoma. It also helps to improve the prognosis even in some aggressive lymphoma, such as peripheral T cell lymphoma.

Objective: To investigate the clinical features, diagnostic methods, and treatment choice of tumor of the papilla of Vater. Methods: The clinical data of 25 patients with tumor of the papilla of Vater treated by local resection in our hospital from December 1983 to May 2006 were retrospectively analyzed. Results: The morbidities of abdominal pain, jaundice and recurrent cholangitis were 84%, 80% and 48%, respectively. The accordant rate for preoperative duodenoscopic biopsy and post-operative pathological diagnosis was 80%. Intraoperative frozen section examination accurately predicted the final pathological results in all the patients. The post-operative complication rate was 20% and the operative mortality rate was 4%. The 5-year survival rates of local resection for benign tumors and malignant tumors were 75% and 28.5%, respectively. Conclusion: Abdominal pain, jaundice and recurrent cholangitis are the main symptoms and signs of tumor of the papilla of Vater. Duodenoscopy is the principal preoperative diagnostic method and intraoperative frozen section examination is reliable in assessing the operative specimens. Selective local resection is an effective treatment option for tumor of the papilla of Vater.
