摘要：

The incidence rate of pancreatic neuroendocrine neoplasms (pNENs) has increased rapidly in recent years. However, the clinicopathological characteristics of pNENs are poorly understood. Medical records of patients who underwent surgery and were confirmed as pNENs by pathological examination from January 2003 to February 2015 in Qilu Hospital were reviewed retrospectively. A total of 100 patients, 36 males and 64 females, were included with a mean operation age of 46.26±13.41 years. Among the 100 cases, 76 had insulinomas and 24 had non-functional pNENs. Tumor size ranged from 0.5 cm to 9 cm, and the mean size was 2.20±1.40 cm. The percentages of TNM stages I, II, III, and IV tumors were 89.0%, 8.0%, 0.0%, and 3.0%, respectively. Based on the WHO classification, pNENs were classified into three grades: G1, G2, and G3. G1, G2, and G3 tumors were confirmed in 72.9%, 23.7%, and 3.4% patients, respectively. The positive rates of CgA and Syn immunohistochemical staining were 94.5% (69/73) and 100% (74/74), respectively. Compared with insulinoma, non-functional pNENs have larger tumor sizes, more advanced TNM staging, a higher Ki-67 index, and a higher rate of liver metastasis (P<0.05). In conclusion, pNENs are heterogeneous tumors with varying clinical manifestations, diverse tumor biological characteristics, and different prognoses. Non-functional pNENs present a more aggressive behavioral model and have poorer prognosis than functional pNENs.

Removal of elemental mercury by KI-impregnated clay

Boxiong SHEN,Jianhong CHEN,Ji CAI

《环境科学与工程前沿（英文）》 2016年第10卷第2期页码 236-243 doi: 10.1007/s11783-014-0765-7

摘要： This study described the use of clay impregnated by KI in gas phase elemental mercury (Hg ) removal in flue gas. The effects of KI loading, temperature, O , SO and H O on Hg removal were investigated using a fixed bed reactor. The Hg removal efficiency of KI-clay with 3% KI loading could maintain at a high level (approximately 80 %) after 3 h. The KI-clay demonstrated to be a potential adsorbent for Hg removal when compared with activated carbon based adsorbent. O was found to be an important factor in improving the Hg removal. O was demonstrated to assist the transfer of KI to I on the surface of KI-clay, which could react with Hg directly. NO and SO could slightly improve Hg removal, while H O inhibited it greatly. The results indicated that after adsorption, most of the mercury escaped from the surface again. Some of the mercury may have been oxidized as it left the surface. The results demonstrated that the chemical reaction primarily occurred between KI and mercury on the surface of the KI-clay.

Towards a respondent-preferred ki-anonymity model

Kok-Seng WONG,Myung Ho KIM

摘要： Recently, privacy concerns about data collection have received an increasing amount of attention. In data collection process, a data collector (an agency) assumed that all respondents would be comfortable with submitting their data if the published data was anonymous. We believe that this assumption is not realistic because the increase in privacy concerns causes some respondents to refuse participation or to submit inaccurate data to such agencies. If respondents submit inaccurate data, then the usefulness of the results from analysis of the collected data cannot be guaranteed. Furthermore, we note that the level of anonymity (i.e., -anonymity) guaranteed by an agency cannot be verified by respondents since they generally do not have access to all of the data that is released. Therefore, we introduce the notion of -anonymity, where is the level of anonymity preferred by each respondent . Instead of placing full trust in an agency, our solution increases respondent confidence by allowing each to decide the preferred level of protection. As such, our protocol ensures that respondents achieve their preferred -anonymity during data collection and guarantees that the collected records are genuine and useful for data analysis.

>In situ growth of phosphorized ZIF-67-derived amorphous CoP/Cu₂O@CF electrocatalyst

《化学科学与工程前沿（英文）》 2023年第17卷第10期页码 1430-1439 doi: 10.1007/s11705-023-2320-1

摘要： Transition metal phosphides have been extensively studied for catalytic applications in water splitting. Herein, we report an in situ phosphorization of zeolitic imidazole frameworks (ZIF-67) to generate amorphous cobalt phosphide/ZIF-67 heterojunction on a self-supporting copper foam (CF) substrate with excellent performance for hydrogen evolution reaction (HER). The needle-leaf like copper hydroxide was anchored on CF surface, which acted as implantation to grow ZIF-67. The intermediate product was phosphorized to obtain final electrocatalyst (CoP/Cu₂O@CF) with uniform particle size, exhibiting a rhombic dodecahedron structure with wrinkles on the surface. The electrochemical measurement proved that CoP/Cu₂O@CF catalyst exhibited excellent HER activity and long-term stability in 1.0 mol·L^–1 KOH solution. The overpotential was only 62 mV with the Tafel slope of 83 mV·dec^–1 at a current density of 10 mA·cm^–2, with a large electrochemical active surface area. It also showed competitive performance at large current which indicated the potential application to industrial water electrolysis to produce hydrogen. First-principle calculations illustrated that benefit from the construction of CoP/ZIF-67 heterojunction, the d-band center of CoP downshifted after bonding with ZIF-67 and the Gibbs free energy (ΔG_H*) changed from –0.18 to –0.11 eV, confirming both decrease in overpotential and excellent HER activity. This work illustrates the efficient HER activity of CoP/Cu₂O@CF catalyst, which will act as a potential candidate for precious metal electrocatalysts.

摘要： Staggered arrays of dimples imprinted on opposite surfaces of an internal flow channel have been formulated numerically to enhance turbulent heat transfer compromising with pressure drop. The channel is simulated with the help of three-dimensional Reynolds-averaged Navier-Stokes (RANS) analysis. Three non-dimensional design variables based on dimple size and channel dimensions and two objectives related to heat transfer and pressure drag have been considered for shape optimization. A weighted-sum method for multi-objective optimization is applied to integrate multiple objectives into a single objective and polynomial response surface approximation (RSA) coupling with a gradient based search algorithm has been implemented as optimization technique. By the present effort, heat transfer rate is increased much higher than pressure drop and the thermal performance also has shown improvement for the optimum design as compared to the reference one. The optimum design produces lower channel height, wider dimple spacing, and deeper dimple as compared to the reference one.

《信息与电子工程前沿（英文）》 2019年第20卷第9期页码 1296-1306 doi: 10.1631/FITEE.1700185

摘要：讨论了一种使用停止等待自动重传请求协议的语音数据集成分组多路复用器的性能。假设输入数据流量经泊松过程呈指数增长，且各数据包在单时隙中传输。同时，假设仅存在单一语音信号，其比数据包有更高优先级，且其流量通过开关马尔可夫过程给出。一旦语音信号被激活，则占用输出链路，阻塞数据包。引入缓冲器占用概念简化分析，并发现当中断信号通过马尔可夫过程给出时，使用停止等待自动重传请求协议的数据多路复用器表现出排队延迟和缓冲行为。仿真结果验证了分析结果的有效性。

基于切换机制的所有子系统不稳定的非周期采样布尔控制网络镇定问题研究 Research Articles

Liang-jie SUN, Jian-quan LU, Wai-Ki CHING

《信息与电子工程前沿（英文）》 2020年第21卷第2期页码 260-267 doi: 10.1631/FITEE.1900312

摘要：本文旨在进一步研究带有非周期采样控制的布尔控制网络的全局稳定性。前期工作指出一个带有非周期采样控制的布尔控制网络能够被转化为一个切换布尔网络；通过研究转化后的切换布尔网络的全局稳定性，可以进一步得到带有非周期采样控制的布尔控制网络的全局稳定性。遗憾的是，由于前期工作主要思想是利用稳定子系统抵消由不稳定子系统引起的状态发散，因此所考虑的切换布尔网络至少含有一个稳定子系统。本文主旨是恰当的切换行为也可以具有良好稳定特性；即当所有子系统都不稳定时，通过设计合适的切换律，切换布尔网络也能达到稳定。这与前期工作的思想完全不同。具体地，对这种情况，首先驻留时间被要求限制在一对上下界内；然后，利用离散化李雅普诺夫函数和驻留时间方法，得到一个全局稳定的充分条件；最后，通过一个生物实例来论证所得结论。

摘要： The continuously increasing production of municipal solid waste incineration bottom ash (MSWIBA) has promoted its utilization as construction material and raised environmental concern. The physico-chemical properties and leaching behavior of MSWIBA were studied, and ecotoxicological testing using a luminescent bacterium bioassay was performed to assess the ecological pollution risks associated with its leached constituents. The MSWIBA was leached by two types of leachants, H SO /HNO and HAc solution, at different liquid to solid ratios and contact times. The concentrations of heavy metals and anions in the leachates were analyzed. Multivariate statistical analyses, including principle component analysis, Pearson's correlation analysis and hierarchical cluster analysis, were used to evaluate the contributions of the constituents to the toxicity ( ) of the MSWIBA leachate. The statistical analyses of the ecotoxicological results showed that the Ba, Cr, Cu, Pb, F and total organic carbon (TOC) concentrations were closely correlated with the value, and these substances were the main contributors to the ecotoxicity of the MSWIBA leachate. In addition, the cluster of these variables indicated similar leaching behaviors. Overall, the research demonstrated that the ecotoxicological risks resulting from MSWIBA leaching could be assessed before its utilization, which provides crucial information for the adaptation of MSWIBA as alternative materials.
