The structure of Fe/Mn catalysts after calcination, reduction and FT synthesis was investigated by means of MES and XRD. With the increase of Mn content, the catalysts gradually changed from magnetic to superparamagnetic state. Therefore, the reduction of catalysts was *** performance of catalysts may be related with the structure of spinel (Fel-y Mny,)3O4 and the value of y. The presence of MnCO3 and MnO could also favor the FT performance. In iron-rich and manganese-rich catalysts, Mn mainly acted as an electronic and structural promoter respectively. For the latter samples, more complex phases were present and lnorc reactions were in competition during the FT performance.

Objective To explore the changes in plasma angiotensin II （Ang Ⅱ） and circadian rhythm of blood pressure among hypertensive patients with sleep apnea syndrome （SAS） before and after continuous positive airway pressure （CPAP） or surgical treatment. Methods A total of 180 essential hypertension patients were enrolled in our study. The determination of plasma Ang Ⅱ concentration, ambulatory blood pressure （ABP）, and polysomnography （PSG） monitoring were performed before and 3 months after CPAP or surgical treatment. Results Patients were classified into three groups by their apnea-hypopnea index （AHI）： essential hypertension group （EH group, n=72; AHI〈5）, essential hypertension with mild SAS group （EH＋mild SAS group, n=60, 5≤AHI〈20）, and essential hypertension with moderate and severe SAS group （EH＋moderate-severe SAS group, n=48, AHI_〉20）. The concentrations of plasma AngⅡ in the above three groups were 13.42±3.27, 16.17±3.82, and 18.73±4.05 ng/mL respectively before treatment, and AngⅡ concentration in EH patients combined with SAS was significantly higher than that in EH group （all P〈0.05）. After treatment the values in the latter two groups significantly decreased to 14.67±2.56 and 15.03±3.41 ng/mL respectively （P〈0.05）. The incidence of non-dipper blood pressure curve in EH patients was 31.9%, and those in hypertensive patients with mild SAS and moderate-severe SAS were 51.7% and 58.3%, respectively before treatment. The incidence of non-dipper blood pressure curve in the EH patients with mild SAS was significantly higher than that of patients with EH alone （P〈0.05）. After CPAP treatment or surgery, the incidence of non-dipper blood pressure curve in the two SAS groups was significantly decreased to 38.3% and 39.6%, respectively （P〈0.05）. Conclusions Ang Ⅱ might play a role in blood pressure variability in patients with obstructive SAS. CPAP or surgical treatment can improve blood pressure disorder and decrease plasma Ang Ⅱ level in patients with obstructive SA

匀速运动模糊作为运动模糊中最基本的模式,在图像复原中一直都倍受关注,其研究成果被广泛应用于其他图像复原以及图像处理中.将图像稀疏表示的思想引入匀速运动模糊图像复原中,提出一种基于l1正则化的复原算法,并利用基追踪算法有效地求解l1正则化的线性规划问题.由于l1在异常值下表现稳健,使得算法对较宽模糊范围下的匀速运动模糊图像都有稳定良好的恢复效果.为了验证算法效果,对该算法与现有算法进行了大量的对比实验,实测结果表明,该算法能准确恢复图像,且有效抑制振铃效应.

Robust Portfolio Selection Based on Optimization Methods

Pituitary apoplexy complicated with subarachnoid hemorrhage caused by incidentaloma following a head injury:case report

第37届中国控制会议

作者： JIN Chu-xin CHEN Wan-yi YU Shu-jing College of Computer and Control Engineering Nankai University Qingdao Campus of Naval Aeronautical University

Linear matrix inequalities（LMI） are used to solve robust portfolio problems and many other control problems. Ellipsoid algorithm and interior-point method are used to solve LMI. In this paper, we consider a robust portfolio model based on Markowitz theory that minimizes the risk at a certain level of return. We turn the model into the LMI with constraints and use ellipsoid algorithm and interior-point method to solve it. A numerical simulation in stock portfolio is given to prove the validity of the method. Because the rate of return is change over time, in order to make the result robust, we use exponentially weighted moving-average（EWMA） method to compute the covariance matrices. Due to the highly reliable result, the model can provide a reference for investors to make decision on portfolio.

Plituitary apoplexy is a rare clinical syndrome caused by acute enlargement of pituitary adenomas, which may be secreting or nonfunctioning, and symptomatic or asymptomatic, resulted from hemorrhage or infarction. Subarachnoid hemorrhage （SAH） is an unusual presentation in patients with pituitary apoplexy, and that following a head injury is more infrequently reported. Here, we report a case of pituitary apoplexy complicated with subarachnoid hemorrhage caused by an incidentaloma after head trauma in an aged man, who experienced a spontaneous regression of the tumor.
