2TIDAL FEATURES IN THE CHINA SEAS AND THEIR ADJACENT SEA AREAS AS DERIVED FROM TOPEX/POSEIDON ALTIMETER DATA显示文摘Some important tidal features of 8 major tidal constituents ( M 2, S 2, K 1, O 1, P 1, Sa, N 2 and K 2 ) in the China Seas and their adjacent sea areas were obtained using six years’ TOPEX/POSEIDON altimeter data. The results showed that the obtained co tidal and co range charts for these major tidal constituents agreed well with those of previous researches using observational data from coastal tidal gauge stations and numerical models.胡建宇 Hiroshi KAWAMURA 洪华生 Fumiaki KOBASⅢ 谢强 2001Chinese Journal of Oceanology and Limnology2001,19,4:9
3IMPROVEMENT IN TENSILE PROPERTIES OF α+β TYPE Ti ALLOYS BY HYDROGEN TREATMENT显示文摘A new process to refine the microstructure of α+βtvpe Ti alloys was developed by usinghydrogen as a temporary alloying element.It involves hydrogenating the alloys below thehydrogenated β transus temperature about 0-40 K,air cooling to room temperature and thendehydrogenating at 948 K.Ti-6AI-4V and Ti-5AI-2.5Fe alloys treated hy this new processshow much refined microstructures,and the yield strength,ultimate strength as well as theelongation increase 8—15,5—13 and 7—14%GONG Bo LAI Zuhan Northeast University of Technology,Shenyang,ChinaNIINOMI Mitsuo,KOBA YASHI Toshiro Toyohashi University of Technology,Toyohashi Japan Department of Physics,Northeast University of Technology,Shenyang 110006,China 1993Acta Metallurgica Sinica(English Letters)1993,6,2:6
4ChatGPT as an Educational Tool: Opportunities, Challenges, and Recommendations for Communication, Business Writing, and Composition Courses显示文摘This empirical study examines ChatGPT as an educational and learning tool.It investigates the opportunities and challenges that ChatGPT provides to the students and instructors of communication,business writing,and composition courses.It also strives to provide recommendations.After conducting 30 theory-based and application-based ChatGPT tests,it is found that ChatGPT has the potential of replacing search engines as it provides accurate and reliable input to students.For opportunities,the study found that ChatGPT provides a platform for students to seek answers to theory-based questions and generate ideas for application-based questions.It also provides a platform for instructors to integrate technology in classrooms and conduct workshops to discuss and evaluate generated responses.For challenges,the study found that ChatGPT,if unethically used by students,may lead to human unintelligence and unlearning.This may also present a challenge to instructors as the use of ChatGPT negatively affects their ability to differentiate between meticulous and automation-dependent students,on the one hand,and measure the achievement of learning outcomes,on the other hand.Based on the outcome of the analysis,this study recommends communication,business writing,and composition instructors to(1)refrain from making theory-based questions as take-home assessments,(2)provide communication and business writing students with detailed case-based and scenario-based assessment tasks that call for personalized answers utilizing critical,creative,and imaginative thinking incorporating lectures and textbook material,(3)enforce submitting all take-home assessments on plagiarism detection software,especially for composition courses,and(4)integrate ChatGPT generated responses in classes as examples to be discussed in workshops.Remarkably,this study found that ChatGPT skillfully paraphrases regenerated responses in a way that is not detected by similarity detection software.To maintain their effectiveness,similarity detection software providers need to upgrade their software to avoid such incidents from slipping unnoticed.Mohammad Awad AlAfnan Samira Dishari Marina Jovic Koba Lomidze 2023Journal of Artificial Intelligence and Technology2023,3,2:5
5不同含量碳水化合物饮食对大鼠心脏和脑18^F-FDG摄取的影响显示文摘目的探讨不同含量碳水化合物饮食对大鼠心脏和脑组织18F-FDG摄取的影响。方法以标准饮食饲养2周后,保持饮食总能量不变,将15只Wistar大鼠随机分为3组:低碳水化合物组(LC)、中碳水化合物组(IC)和高碳水化合物组(HC);每组大鼠每种饮食饲养4周后,对动物行18F-FDGPET全身显像,于第2天尾静脉取血测定酮体、葡萄糖、胰岛素和胰高血糖素的含量。图像经计算机处理,获取心脏和脑的最大标准摄取值(SUVmax)。结果心脏SUVmax分别为:LC组3.27±0.43,IC组10.92±0.89,HC组10.95±0.81;脑SUVmax:LC组4.78±0.19,IC组4.04±0.15,HC组3.77±0.24。LC组与IC和HC组之间的差异均有统计学意义(P<0.001),IC和HC组间差异无统计学意义。LC组酮体为(726.10±65.95)μmol/L,约为IC和HC组的6~7倍;血清酮体水平与心脏SUVmax呈负相关(r=-0.764,P<0.001),与脑SUVmax呈正相关(r=0.569,P<0.001);各组间血清胰岛素、血糖和胰高血糖素的差异均无统计学意义。结论长期极低碳水化合物饮食使大鼠心脏对FDG的摄取明显降低,而脑组织对葡萄糖的摄取略有增加。缪蔚冰 王荣福 BLAUFOX M Donald FINE Eugene J KOBA Wade 2009中国医学影像技术2009,,7:4
6Noise Characteristics of Centrifugal Blower with Low Solidity Cascade Diffuser(Noise Reduction by means of Small Groove Located at LSD Blade Leading Tip)显示文摘This paper deals with the effect of the blade tip-groove of the low solidity cascade diffuser (LSD) on the blowercharacteristic and the noise generated by the LSD. The small grooves were set up at the root and/or tip near theleading edge of the LSD blade. In order to clarify the mechanism of noise increase due to LSD and also to reducethe noise, the relationships between the noise increase based on the LSD, the LSD performance and the secondaryflow formed additionally by the tip-groove were investigated experimentally as well as numerically, especiallyanalyzing flow behaviors in the LSD in view points of flow separation on the suction surface of the LSD bladeand the secondary flow on the side walls. By reducing the stagnation region smaller near the root and/or tip of theLSD blade leading edge, the secondary flow behavior changes remarkably around the LSD blade, as a result, thenoise level and the blower characteristics vary. It can be concluded that, by means of a small tip-groove locatedonly at the shroud side near the LSD blade leading edge, the noise generated by the LSD can be reduced withoutdeteriorations of the LSD performance and the blower characteristics as well.Tengen MURAKAMI Masahiro ISHIDA Daisaku SAKAGUCHI Yu KOBA 2009Journal of Thermal Science2009,18,4:3
7Long-lasting responses after discontinuation of nivolumab treatment for reasons other than tumor progression in patients with previously treated,advanced non-small cell lung cancer显示文摘Dear Editor,Nivolumab,an inhibitor of programmed cell death 1(PD-1),is an immune checkpoint inhibitor(ICI)that enhances T cell functions by preventing negative regulation of cancer immunity,and it has shown clinically significant efficacy and tolerability in various types of cancer.Based on the results of randomized phase III trials comparing nivolumab with docetaxel[1,2],nivolumab is now used in clinical practice for patients with previously treated advanced non-small cell lung cancer(NSCLC).Fur-thermore,the most recent Japan Lung Cancer Society guidelines include nivolumab monotherapy in the sys-temic treatment strategy for previously treated,locally advanced or metastatic NSCLC[3].However,ICIs induce characteristic immune-related adverse events(irAEs),which are not seen with conventional cytotoxic agents or molecular targeted agents.IrAEs can occur in any organ system,most typically the skin,lung,and gastrointesti-nal,hepatic,and endocrine systems.Hideharu Kimura Tomoyuki Araya Taro Yoneda Hiroki Shirasaki Koji Kurokawa Tamami Sakai Hayato Koba Yuichi Tambo Shingo Nishikawa Takashi Sone Kazuo Kasahara 2019Cancer Communications2019,39,1:3
