西方戏剧魅力的回归——浅析西方戏剧特征在电影《电话亭》中的体现

电影《电话亭》（Phone Booth）充分体现了西方戏剧的一些重要的特征。《电话亭》舍弃了电影擅长的时空及人物的多样性,选择恪守传统戏剧的“三一律”,只利用非常有限的场景、时间和人物,制造出一波三折的戏剧性冲突,体现了西方戏剧是激变型的艺术这一特征。此外影片还体现了基督教的“性恶论”与西方悲剧的关联,具有警世的意味。

A Performance Evaluation of Classic Convolutional Neural Networks for 2D and 3D Palmprint and Palm Vein Recognition

Palmprint recognition and palm vein recognition are two emerging biometrics technologies. In the past two decades, many traditional methods have been proposed for palmprint recognition and palm vein recognition, and have achieved impressive results. However, the research on deep learning-based palmprint recognition and palm vein recognition is still very preliminary. In this paper, in order to investigate the problem of deep learning based 2D and 3D palmprint recognition and palm vein recognition in-depth, we conduct performance evaluation of seventeen representative and classic convolutional neural networks (CNNs) on one 3D palmprint database, five 2D palmprint databases and two palm vein databases. A lot of experiments have been carried out in the conditions of different network structures, different learning rates, and different numbers of network layers. We have also conducted experiments on both separate data mode and mixed data mode. Experimental results show that these classic CNNs can achieve promising recognition results, and the recognition performance of recently proposed CNNs is better. Particularly, among classic CNNs, one of the recently proposed classic CNNs, i.e., EfficientNet achieves the best recognition accuracy. However, the recognition performance of classic CNNs is still slightly worse than that of some traditional recognition methods.

     

破乳剂与原油管道混合流动的数值模拟

原油开采过程中,原油遇水能够形成比较稳定的乳化液,添加破乳剂是快速高效脱去原油中水的最有效的方法。对破乳剂与原油两相混合的流动形态进行了数值模拟,得出破乳剂在不同速度、不同入口角度下加入原油管道后两相流动的速度分布图和浓度分布图。经过对比发现,当药剂入口角度为0°,药剂流入速度越大,越有利于破乳剂的扩散,破乳剂和原油的混合效果最好,就更有利于原油的脱水。     

Degradability and biocompatibility of bioglass/poly(amino acid) composites with different surface bioactivity as bone repair materials

Bioglass (BG) possesses excellent bioactivity and has been widely used in the manufacture of biomaterials. In this study, a composite with different surface bioactivity was fabricated via in situ melting polymerization by incorporating BG and poly(amino acid) (PAA) at a suitable ratio. The structure of the composite was characterized by Fourier transform infrared spectroscopy and XRD. The compressive strength of the BG/PAA composites was 139 MPa (BG:PAA = 30:70). The BG/PAA composites were degradable, and higher BG in composite showed higher weight loss after 4 weeks of incubation in simulated body fluid. In addition, the BG/PAA composite maintained adequate residual compressive strength during the degradation period. The SEM results showed the differences in surface bioactivities of the composites directly, and 30BG/PAA composite showed thicker apatite layer and higher Ca/p than 15BG/PAA. in vitro MG-63 cell culture experiments showed that the composite was noncytotoxic and thus allows cells to adhere, proliferate, and differentiate. This indicates that the composite has good biocompatibility. The implantations in the bone defects of rabbits for 4 and 12 weeks were studied. The composites had good biocompatibility and were capable of guiding new bone formation without causing any inflammation. The composite may be successfully used in the development of bone implants.
