1采用动态推-拉技术增强动脉瘤分流器的导流作用:一项实验和模型研究显示文摘目的 神经血管分流器是治疗颅内动脉瘤的一种有弹性的、纵横交错的网状支架。本研究采用动态推-拉技术调节动脉瘤瘤口分流器的网格密度,以便最大化其导流作用。通过自主研发的高保真虚拟支架计算机模型技术联合计算机流体动力学,探讨动态推-拉技术对特定动脉瘤病人血流动力学的影响。方法采用动态推-拉技术和不同长度的传送导线,将两个Pipeline分流器放置到两个相同侧壁的大脑前动脉动脉瘤模型中。然后数字模拟操作过程,并验证模拟的网格几何结构。通过调节放置在侧壁动脉瘤和基底动脉主干梭形动脉瘤(前期已放置分流器)的分流器,采用计算机流体动力学分析,评估血流动力学的具体变化。同时评估来源于临床病例样本的分流器网格的影像。Ma D Xiang J Choi H 周静 郭玉慧 2014中国微侵袭神经外科杂志2014,19,6:12

3Discovering the roles of subsurface microorganisms: Progress and future of deep biosphere investigation显示文摘The discovery of the marine 'deep biosphere'-microorganisms living deep below the seafloor-is one of the most significant and exciting discoveries since the ocean drilling program began more than 40 years ago. Study of the deep biosphere has become a research frontier and a hot spot both for geological and biological sciences. Here, we introduce the history of the discovery of the deep biosphere, and then we describe the types of environments for life below the seafloor, the energy sources for the living creatures, the diversity of organisms within the deep biosphere, and the new tools and technologies used in this research field. We will highlight several recently completed Integrated Ocean Drilling Program Expeditions, which targeted the subseafloor deep biosphere within the crust and sediments. Finally, future research directions and challenges of deep biosphere investigation towards uncovering the roles of subsurface microorganisms will be briefly addressed.WANG FengPing LU ShuLin ORCUTT Beth N XIE Wei CHEN Ying XIAO Xiang EDWARDS Katrina J 2013Chinese Science Bulletin2013,58,4:6

5二甲双胍通过沉默MATE1表达富集在细胞内选择性抑制KRAS突变转移性结肠癌显示文摘结肠癌(CRC)是常见癌症之一,转移是导致死亡的主要原因。近期研究发现一线化疗药物伊立替康或奥沙利铂联合表皮生长因子受体(EGFR)靶向药物可将转移性结直肠癌(mCRC)患者中位总体生存期提高2年以上。然而,KRAS突变的结肠癌患者(约30%~50%)表现对EGFR靶向药物的耐药性。因此,EGFR靶向药物不能用于KRAS突变的mCRC患者治疗。前期多项研究指出二甲双胍具有抗肿瘤作用,且服用二甲双胍与患者良好预后密切相关。然而,多项回顾性研究发现二甲双胍与癌症患者预后不相关,关于二甲双胍对肿瘤的治疗作用及分子机制尚存在诸多问题和分歧。安华英(编译) Xie J Xia L Xiang W 2020中华医学杂志2020,100,32:5

7All-optical neuromorphic binary convolution with a spiking VCSEL neuron for image gradient magnitudes显示文摘All-optical binary convolution with a photonic spiking vertical-cavity surface-emitting laser(VCSEL) neuron is proposed and demonstrated experimentally for the first time, to the best of our knowledge. Optical inputs, extracted from digital images and temporally encoded using rectangular pulses, are injected in the VCSEL neuron,which delivers the convolution result in the number of fast(<100 ps long) spikes fired. Experimental and numerical results show that binary convolution is achieved successfully with a single spiking VCSEL neuron and that alloptical binary convolution can be used to calculate image gradient magnitudes to detect edge features and separate vertical and horizontal components in source images. We also show that this all-optical spiking binary convolution system is robust to noise and can operate with high-resolution images. Additionally, the proposed system offers important advantages such as ultrafast speed, high-energy efficiency, and simple hardware implementation,highlighting the potentials of spiking photonic VCSEL neurons for high-speed neuromorphic image processing systems and future photonic spiking convolutional neural networks.YAHUI ZHANG JOSHUA ROBERTSON SHUIYING XIANG MATĚJ HEJDA JULIÁN BUENO ANTONIO HURTADO 2021Photonics Research2021,9,5:4
