15一个中国边缘海的风-浪-流预报系统显示文摘海洋预报是进行海上活动的安全保障,海洋预报系统技术已经成为现代海洋气象业务的技术支撑。海洋观测、数据同化、数值模拟和高性能计算机等技术的进步极大地推动着海洋业务化预报的发展。采用大气数值模式(WRF)、海洋数值模式(CROCO)和海浪数值模式(SWAN)的多模式高分辨率离线耦合方式,添加南京信息工程大学“海洋数值模拟与观测实验室”团队自主研发的一系列海洋模式参数化方案,包括浪致混合参数化方案、亚中尺度参数化方案、海山诱导混合参数化方案以及涡旋诱导的沿等密度面和跨等密度面混合参数化方案,并通过同化技术和最新的人工智能技术与观测资料相结合,构建一种面向中国边缘海的风浪流多参数耦合预报系统,用于海上风电功率的预报和其他海洋灾害预警。实际观测资料的验证表明,该预报系统能较准确地模拟海上风场、海流、海温、波浪、潮汐等海洋气象要素。同时实现了按需实时可视化全景展示。董昌明 LIM KAM SIAN Kenny Thiam Choy 蒋星亮 曹玉晗 嵇宇翔 王森 余洋 陆晓婕 周书逸 韦销蔚 BETHEL Brandon Justin 徐广珺 董济海 孙文金 王海丽 单海霞 王锦 王东霞 滕芳园 曹茜 谢文鸿 游志伟 王子韵 林连杰 2022海洋科学进展2022,40,4:0
16A Systematic Approach for Making 3D-Printed Patient-Specific Implants for Craniomaxillofacial Reconstruction显示文摘Craniomaxillofacial reconstruction implants,which are extensively used in head and neck surgery,are conventionally made in standardized forms.During surgery,the implant must be bended manually to match the anatomy of the individual bones.The bending process is time-consuming,especially for inexperienced surgeons.Moreover,repetitive bending may induce undesirable internal stress concentration,resulting in fatigue under masticatory loading in v iv o and causing various complications such as implant fracture,screw loosening,and bone resorption.There have been reports on the use of patient-specific 3D-printed implants for craniomaxillofacial reconstruction,although few reports have considered implant quality.In this paper,we present a systematic approach for making 3D-printed patientspecific surgical implants for craniomaxillofacial reconstruction.The approach consists of three parts:First,an easy-to-use design module is developed using Solidworks®software,which helps surgeons to design the implants and the axillary fixtures for surgery.Design engineers can then carry out the detailed design and use finite-element modeling(FEM)to optimize the design.Second,the fabrication process is carried out in three steps:0 testing the quality of the powder;(2)setting up the appropriate process parameters and running the 3D printing process;and (3)conducting post-processing treatments(i.e.,heat and surface treatments)to ensure the quality and performance of the implant.Third,the operation begins after the final checking of the implant and sterilization.After the surgery,postoperative rehabilitation follow-up can be carried out using our patient tracking software.Following this systematic approach,we have successfully conducted a total of 41 surgical cases.3D-printed patient-specific implants have a number of advantages;in particular,their use reduces surgery time and shortens patient recovery time.Moreover,the presented approach helps to ensure implant quality.Ruxu Du Yu-Xiong Su Yu Yan Wing Shan Choi Wei-Fa Yang Chunyu Zhang Xianshuai Chen Justin Paul Curtin Jianglin Ouyang Bitao Zhang 2020Engineering2020,6,11:0
17The host-targeting compound peruvoside has a broad-spectrum antiviral activity against positive-sense RNA viruses显示文摘Positive-sense RNA viruses modify intracellular calcium stores,endoplasmic reticulum and Golgi apparatus(Golgi)to generate membranous replication organelles known as viral factories.Viral factories provide a conducive and substantial enclave for essential virus replication via concentrating necessary cellular factors and viral proteins in proximity.Here,we identified the vital role of a broadspectrum antiviral,peruvoside in limiting the formation of viral factories.Mechanistically,we revealed the pleiotropic cellular effect of Src and PLC kinase signaling via cyclin-dependent kinase 1 signaling leads to Golgi-specific brefeldin A-resistance guanine nucleotide exchange factor 1(GBF1)phosphorylation and Golgi vesiculation by peruvoside treatment.The ramification of GBF1 phosphorylation fosters GBF1 deprivation consequentially activating downstream antiviral signaling by dampening viral factories formation.Further investigation showed signaling of ERK1/2 pathway via cyclin-dependent kinase 1 activation leading to GBF1 phosphorylation at Threonine 1337(T1337).We also showed 100%of protection in peruvoside-treated mouse model with a significant reduction in viral titre and without measurable cytotoxicity in serum.These findings highlight the importance of dissecting the broad-spectrum antiviral therapeutics mechanism and pave the way for consideration of peruvoside,host-directed antivirals for positive-sense RNA virus-mediated disease,in the interim where no vaccine is available.Kan Xing Wu Thinesshwary Yogarajah Marcus Wing Choy Loe Parveen Kaur Regina Ching Hua Lee Chee Keng Mok Yi Hao Wong Patchara Phuektes Li Sze Yeo Vincent T.K.Chow Yong Wah Tan Justin Jang Hann Chu 2023Acta Pharmaceutica Sinica B2023,13,5:0
