旅游标识语英译研究是翻译领域的一个重要课题。该研究从生态翻译学的三维理论视角对红色景点韶山的旅游标识语的英译规范化进行深入研究。通过对景区内标识语的英译案例进行分析,探究标识语英译中存在的不规范现象,并据此提出相应的策略。研究发现,旅游标识语英译不规范主要体现在拼写错误、语法错误、专有名词英译不统一、译文表意不清,以及忽略文化差异导致的翻译问题,而景区标识语的规范化需政府、高校、企业及社会的共同努力。规范的旅游标识语英译能为外国游客提供更准确、更流畅的信息,有利于韶山景区的对外宣传,助推韶山旅游业发展的同时也有助于红色文化的国际传播。

A review on the research of Micro Electromechanical Systems （MEMS） technology based biomimetic cilia is presented. Biomimetic cilia, enabled by the advancement of MEMS technology, have been under dynamic development for the past decade. After a brief description of the background of cilia and MEMS technology, different biomimetic cilia applications are reviewed. Biomimetic cilia micro-actuators, including micromachined polyimide bimorph biomimetic cilia micro-actuator, electro-statically actuated polymer biomimetic cilia micro-actuator, and magnetically actuated nanorod array biomimetic cilia micro-actuator, are presented. Subsequently micromachined underwater flow biomimetic cilia micro-sensor is studied, followed by acoustic flow micro-sensor. The fabrication of these MEMS-based biomimetic cilia devices, characterization of their physical properties, and the results of their application experiments are discussed.

Despite the success of combined antiretroviral therapy in recent years, the prevalence of human immunodeficiency virus(HIV)-associated neurocognitive disorders in people living with HIV-1 is increasing, significantly reducing the healthrelated quality of their lives. Although neurons cannot be infected by HIV-1, shed viral proteins such as transactivator of transcription(Tat) can cause dendritic damage. However, the detailed molecular mechanism of Tat-induced neuronal impairment remains unknown. In this study, we first showed that recombinant Tat(1–72 aa) induced neurotoxicity in primary cultured mouse neurons. Second, exposure to Tat_(1–72) was shown to reduce the length and number of dendrites in cultured neurons. Third, Tat_(1–72)(0–6 h) modulates protein phosphatase 1(PP1) expression and enhances its activity by decreasing the phosphorylation level of PP1 at Thr320. Finally, Tat_(1–72)(24 h) downregulates CREB activity and CREBmediated gene(BDNF, c-fos, Egr-1) expression. Together, these findings suggest that Tat_(1–72) might impair cognitive function by regulating the activity of PP1 and the CREB/BDNF pathway.

The performances of a novel foaming agent used in the preparation process of aluminum foams were investigated, and the effects of some factors, such as addition of the foaming agent, foaming temperature on the porosity, and appearance of aluminum foams were also discussed. Experimental results show that the novel foaming agent has a wide decomposition temperature range and a mild decomposed rate; the foaming agent has the ability to enhance the viscosity of aluminum melt, as a result, an extra viscosifier such as Ca or SiCp is unnecessary while using this foaming agent; the bubble-free zone in material decreases and the foaming effi- ciency increases with the increase of foaming agent; the bubble-free zone disappears and the foaming efficiency is near 100% when the addition of foaming agent is more than 1.4wt%; the porosity of the aluminum foam increases with the increase of foaming agent when the addition of foaming agent is less than 2.2wt%.

Objective： To study the clinicopathological characters Methods： A total of 629 patients with breast cancer of triple negative breast cancer （TNBC）. were reviewed, who were treated from 2003 to 2007 in Chongqing Cancer Institute. The comparison of clinicopathological features including TNM classification, histological type, tumor location, axillary lymphonodes status and neoadjuvant chemotherapy between TNBC and nontriple negative breast cancer （NTNBC） was performed. The overall response was evaluated by whether the patients achieve complete remission （CR） and partial remission （PR） after chemotherapy. Results： There were 69 TNBCs in the 629 patients with breast cancer. The premenopausal patients, which was found in 49/69 of TNBCs, was more than NTNBCs. The average diameter of tumor in TNBC group was 4.1 cm, lager than NTNBC group. TNBC with axillary nodes metastasis occurred in 21 cases, and the axillary nodes metastasis rate was lower than NTNBC. The positive expression rate of p53 in TNBC was 44.9%, and the overall response （CR＋PR） was 72.2%. No statistical differences were found regarding the positive expression rate of p53 and the overall response between TNBC and NTNBC. Conclusion： TNBC were a group of primary breast cancers with triple negative, tending to occur in premenopausal women, with larger tumors, lower axillary nodes metastasis rate. TNBC had worse clinical prognosis and currently lacked effective targeted therapies.

目前的文档信息抽取方法大多针对简单的文档,在抽取包含背景干扰和结构复杂的金融票据时效果不佳。针对复杂金融票据中实体关系难以正确匹配的问题,提出了顺序重构方法和LayoutLMv3-GRU信息抽取模型。构建背景复杂的金融票据数据集,利用文本、布局和图像三个模态进行信息抽取。利用Layout-Parser工具,设计排序模块,使文本信息按照上下文关系排序,并把空间距离较远且逻辑关系较近的单词进行重新的排列组合。通过结合改进的LayoutLMv3模型与GRU网络,使模型的准确率进一步提升。并在公共数据集FUNSD与自建的复杂金融数据集进行实验。结果表明,该方法的F1值比LayoutLM3模型提升2.37%。尤其在自建的复杂金融数据集上,模型F1值达到了88.36%,验证了该方法在抽取复杂票据信息时的优越性与处理各种文档时的通用性。
