The post-infarcted related ventricular tachycardia (VT) is considered associated with increase in mortality or sudden cardiac death (SCD). Implantable cardioverter defibrillation (ICD) has been the standard therapy for the first or second prevention of SCD after myocardial infarction (MI). Incessant VT, which has poor response to anti-arrhythmic drugs and can cause repetitive ICD shock, is usually a tough problem in clinical practice. According to the guideline, incessant infracted related VT could be treated with catheter ablation.[1] Herein we reported a case of refractory scar-induced VT accompanied with thrombus in the left chamber, which was full with ups and downs during the therapy.

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.

Silicon photonics has provided a platform for the convergency of photonic devices and electronic circuits, facilitating the development of optical telecommunications and optical interconnects on chip[1]. As the basic building block of optical communication systems, electro-optic tuning is expected to be more compact, high bandwidth, energy efficient, and allow for CMOS-compatible fabrication in the future[2]. Resonator-based electro-optic tuning has attracted more and more interest due to the small footprint, enhanced light-matter interactions and high energy efficiency. Compared with microring and microdisk resonators, photonic crystal nanobeam cavities （PCNBCs） realize higher quality factors, stronger light-matter interactions, ultrasmall mode volume and a much larger free spectral range （FSR）[3].

容积视频捕获(Volumetric Video)是通过光学扫描来捕捉拍摄对象并生成动静两态4D数字影像模型的前沿机器视觉技术之一。与现有的虚拟数字人不同,它生成的数字克隆人是对真人一比一的真实呈现,故而数字克隆人所具有的视觉情感与叙事场景于受众而言具有更深刻的沉浸性。本文从数字克隆人的生成逻辑、技术特性出发,深挖其背后生发的感知体验与情感投射,通过跨媒介叙事分析,结合实验室成果探索其沉浸意境与实践意义,揭示数字克隆人在经历“生产—创造”的过程后将客观形态和主观感性融合在一起,冲破了人与技术、人与审美、人与群体的边界,在虚拟世界中转化为现实的仿真。
