《降临》之下的环形语言结构

当代电影 2017年第6期 165-168页

作者：王玉洁浙江大学比较文学与世界文学研究所 2012级博士研究生310028

关于语言与思维的关系,学界一直争论不休。2016年,加拿大导演丹尼斯·维伦纽瓦执导的科幻巨制《降临》改编自星云奖获得者特德·姜的小说《你一生的故事》,在科幻主题下重述了语言在人类思维形成中的奠定性作用。全片以语言学家萨丕尔-... 详细信息

关于语言与思维的关系,学界一直争论不休。2016年,加拿大导演丹尼斯·维伦纽瓦执导的科幻巨制《降临》改编自星云奖获得者特德·姜的小说《你一生的故事》,在科幻主题下重述了语言在人类思维形成中的奠定性作用。全片以语言学家萨丕尔-沃尔夫假说为理论基石,讲述了外星生物七肢桶所持环形符号的语言赋予了片中语言学家环形的时间视觉能力,过去、现在与未来的现实构成一种首尾相接环状关系。这实际是在科幻外衣下再次表征了语言在去除语音之后,文字能指与思维的关系密切的关系。

Zwitterionic surfactants whose hydrophilic polar heads carry both positive and negative charges, are a kind of important surfactants [1]. In this paper, we investigated two types of zwitterionic surfactants,amino-acid surfactants and dodecyl dimethyl(3-sulfopropyl)-ammonium, which all are ***-acid surfactants are composed of polar amino acid or oligopeptide(hydrophilic moiety) and non-polar alkyl chain(hydrophobic moiety)[2]. In this work, three different sets of cationic surfactants from glycine have been synthesized. These compounds were confirmed using 1H NMR spectroscopy and studied by several methods like conductivity and polarization microscope. The interaction of dodecyl dimethyl(3-sulfopropyl)-ammonium with anionic surfactants like SDS(sodium dodecyl sulfate)were studied by DSC(differential scanning calorimetry)[3]. The results showed that amino-acid surfactants presented lower cmc(critical micelle concentration), lower Krafft temperature and better biological performance compared with traditional surfactants, which is important for biotechnological applications.

M-MOF-74吸附分离H_(2)/He混合物的分子模拟研究

河南省化学会2016年学术年会

作者： Jiuxia wang Qiaozhen Zuo Na Li Yi wang yujie wang Guangyue Bai School of Chemistry and Chemical Engineering Henan Institute of Science and Technology School of Chemistry and Chemical Engineering Key Laboratory of Green Chemical Media and Reactions Ministry of Education Henan Normal University

Influence of the surfactant headgroup on the activity of horseradish peroxidase(HRP) was investigated after incubating the protein in buffered(10 m M phosphate solution) sodium dodecyl sulfate(SDS), dodecyl trimethyl ammonium bromide(DTAB) and N-dodecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate(SB3-12), which have the same hydrophobic tail but different hydrophilic headgroups. The activity of HRP incubated in all these surfactant solutions were examined with the oxydized rate of TMB into TMB cation radical(TMB·+) recorded at 652 nm, or Pyrogallol into Purpurogallin recorded at 420 nm, respectively. HRP activity decreases steeply in different profiles as the concentrations of SDS and DTAB increase and the complete denaturation occurs when the concentrations are above the critical micelle concentration(cmc) of SDS or DTAB. In contrast, the activity of HRP is preserved almost constant below the critical micelle concentration(cmc) of zwitterionic surfactant SB3-12, and a downward trend is observed after the cmc value of SB3-12. The effect of the surfactants on the enzyme correlate with the charged headgroups.

为了探究有机金属框架MOF-74能否作为一种优良的固体吸附剂,分离H_(2)/He混合物中H_(2),并达到提纯He的目的,采用分子模拟的手段研究了H_(2)、He及H_(2)/He混合物在M-MOF-74(M=Mg、Co、Ni、Cu、Zn)上的吸附性能及吸附机理。结果表明,在1 bar(1 bar=105 Pa)压力和25℃条件下,纯H_(2)对纯He在Ni-MOF-74上的选择性达6.58,而Mg-MOF-74对H_(2)的吸附量最大,其值为0.19 mmol·cm^(-3),为He吸附量的6.46倍。当H_(2)/He混合物的浓度发生变化时,对其在M-MOF-74上的吸附分离因子没有较大影响,说明浓度变化不会影响M-MOF-74上吸附位点容纳H_(2)和He的能力。吸附位点和吸附热分析表明,MOF-74上的金属离子未饱和位点能够显著增强其对H_(2)的吸附能力。其结果对判断M-MOF-74是否具有分离H_(2)/He混合物的潜力,以及定量分析MOFs金属未饱和位点对H_(2)/He混合物分离的贡献提供了一定的理论基础。

外水压力是深埋隧洞建设中面临的一个关键问题,由于深埋隧洞埋深大、地下水位高、地层间水力联系规律复杂,因此给深埋隧洞外水压力确定提出巨大挑战。厘清隧洞全生命周期地下水的水力联系规律,是准确评价深埋隧洞外水压力和隧洞建设影响地下水环境的关键。该文采用数值模拟法研究不同地层类型对隧洞开挖后地下水演化规律的影响,在此基础上,提出一种深埋隧洞地下水分层水力联系地表深孔监测技术,并应用于滇中引水工程蔡家村隧洞。数值模拟结果显示:隧洞上方存在隔水地层对开挖后地下水水力联系有显著影响。工程实践应用不仅验证了该技术的可行性,还证实了深埋隧洞地下水水力联系存在分层现象。该文提出的深埋隧洞地下水分层水力联系地表深孔监测技术为深埋隧洞高外水压力的取值研究提供了有效手段。

针对由源域训练的行人再识别模型通常在目标域的泛化能力不强的问题,提出基于图卷积神经网络的跨域行人再识别方法,将源域数据学习到的整合邻居样本信息的能力迁移至目标域数据.首先,为经过特征提取后的源域数据建立亲属子图,并将源域数据特征和亲属子图作为所设计的图卷积神经网络模块的输入,以基于源域的监督信息训练图卷积神经网络模块;然后,对经过特征提取后的目标域数据建立亲属子图,将训练过的图卷积神经网络模块应用于目标域数据,为目标域数据赋伪标签;最后,联合源域数据和目标域数据训练得到一个泛化能力强的行人再识别模型.分别在两个大规模公开数据集Market-1501和DukeMTMC-reID上对所提出方法进行实验验证,结果表明所提出的方法与所选择的基准模型相比使得Market-1501的rank-1准确率和平均准确率均值(mAP)分别提高了7.4%和9.2%,而DukeMTMC-reID的rank-1准确率和m AP分别提高了14.2%和14.9%.

[Objectives]This study was conducted to optimize the extraction process of Sipunculus nudus polysaccharide and study the antioxidant activity of S. nudus polysaccharide. [Methods] S. nudus polysaccharide was extracted by ultrasonic microwave assisted method,during which univariate factors including solidliquid ratio,time,temperature,ultrasonic power,microwave power were investigated,to select optimal extracting conditions,which were also verified by an response surface optimization experiment( an four-factor three-level test); and the antioxidant activity of S. nudus polysaccharide was studied by determining its DPPH radical scavenging capacity. [Results]Through univariate factor investigation and response surface optimization test,it was found that the response surface results were consistent with univariate results. The optimized conditions were as follows: solid-liquid ratio at 1∶ 15,ultrasonic temperature at 60 ℃,ultrasonic power of 360 W and microwave power of 200 W,and the predicted polysaccharide extracting amount was 4. 35 mg/g. Under the optimized extracting conditions,the average extracting amount of S. nudus polysaccharide was 4. 38 mg/g,which is close to the theoretical predicted value( 4. 35 mg/g). And the results of this study also showed that different concentrations of polysaccharide solutions have different scavenging effects on DPPH free radical. At the polysaccharide concentration of0. 16 mg/ml,the maximum value of DPPH radical scavenging rate was 7. 22%,indicating that polysaccharide has certain antioxidant capacity. [Conclusions]This method is a new trial with satisfactory results.

经尿道膀胱肿瘤电切术(TURBT)后行膀胱灌注已经成为目前公认的预防和治疗非肌层浸润性膀胱肿瘤(NMIBC)最重要、最有效的手段。现阶段TURBT术后灌注治疗主要选择化疗药物和卡介苗(BCG)。对于所有非肌层浸润型的患者,术后及早期都应给予膀胱灌注治疗;对于G_(1～2)Ta期患者使用术后单次的化学药物灌注治疗即可;对于中危患者,推荐使用单次药物灌注+诱导灌注或持续灌注的治疗模式,但灌注药物使用的具体方案应根据患者具体情况制定相应的治疗计划;对于高危患者,术后应首选BCG的灌注治疗;化疗药物和BCG联合的序灌疗法对于治疗膀胱肿瘤有无优势,其疗效还需进一步验证。虽然膀胱药物灌注治疗的研究已经有很长的历史,但在药物的使用方面,如药物的选择,使用时间,及剂量方面仍没有统一的观点。本文对非肌层浸润型膀胱肿瘤TURBT术后膀胱灌注治疗的策略进行综述。
