A Smooth 1-Parameter Family of Delaunay-Type Domains for an Overdetermined Elliptic Problem in and
No full textWe prove the existence of a non-compact smooth one-parameter family of domains Ωs⊂Mn×R, where Mn denotes the Riemannian manifold Sn or Hn (for n≥2), bifurcating from the straight cylinder B1×R (where B1 is a geodesic unit ball in Mn) such that there exists a positive solution u to (Formula presented.) for some positive constant λ, where g is the standard metric in Mn×R, and ν represents the unit normal vector about ∂Ωs. The domains Ωs are not straight cylinders but are periodic in the direction of R. This improves a previous result by the second and third author
A Re-Evaluation of Song Dynasty Epigraphy : A Perspective on Its Connection with Scholar-Official Society
No full textapplication/pdfThe aim of this paper is to study the position of Song dynasty epigraphy（ Jinshixue）in Chinese academic history. The first part of the paper seeks to clarify the connotation of Song dynasty epigraphy by critiquing the traditional definition of Chinese epigraphy held by many contemporary scholars. By reviewing the process of the establishment of the field of Song dynasty epigraphy, this elegant hobby of inscriptions is explained as an aesthetic art form which then developed into an academic discipline.Finally, the paper illustrates the relationship between the formation of the Song dynasty epigraphy and the maturity of the scholar-official society. It would become the representative knowledge of the Song dynasty, prompting the well-known scholar Wang Guowei to say, “It is in fact the academic discipline of the Song era”, inseparable from the characteristics of the scholar-official class, such as geography, regionalism and the formation of the knowledge community.departmental bulletin pape
“The formation of modern written language. Writing categories and polysyllabic words”
No full textIn his “Wenxue gailiang chuyi” (A tentative proposal for the reform of literature), Hu Shi set forth the necessity to reform both the gist and the form of literature. Thereafter, he recognised the close connection between the reform of literature and that of the Chinese language, advancing the proposals of “Jianshe de wenxue geming lun: guoyu de wenxue, wenxue de guoyu” (The theory of a constructive literary revolution: a literature in the national language, a national literary language). Nevertheless, when looking at the history of the Xixue Dongjian (The transfer of Western knowledge to the East) from the 16th century onwards, the connections between the Chinese language and the presentation of modern knowledge, i.e. the recounting of science, are broader and more thorough than the contents touched upon by “literature”. A question of the uttermost importance was how to employ the Chinese language to narrate science; after Hu Shi, personalities such as Chen Duxiu, Liu Bannong and Fu Sinian discussed the difference between literary and non-literary writings from the perspective of language form. In this article, the author examines the possibility for the Chinese language to convey modern knowledge at the turn of the 19th and 20th century, what transformations the Chinese language required in order to achieve this purpose and the question of whether the national language dictionary Ciyuan prepared the way for it
Molecular beam epitaxy growth of InGaSb/AlGaAsSb strained quantum well diode lasers
No full text2μm InGaSb/AlGaAsSb strained quantum wells and a tellurium-doped GaSb buffer layer were grown by molecular beam epitaxy(MBE). The growth parameters of strained quantum wells were optimized by AFM, XRD and PL at77 K. The optimal growth temperature of quantum wells is440°C. The PL peak wavelength of quantum wells at300 K is1.98μm, and the FWHM is115 nm. Tellurium-doped GaSb buffer layers were optimized by Hall measurement. The optimal doping concentration is1.127×1018 cm-3 and the resistivity is5.295×10-3Ωcm.?2011 Chinese Institute of Electronics
A Study of Modern Chinese Disyllabic Words: An Introduction to Language Contact and Modernization of Chinese
No full textKey Leaders’ Opinion on Peri-Operative Risk Factor and Therapeutic Strategy in Lung Cancer Surgery
No full textPerioperative care remains a hot and controversial issue to thoracic surgeons with their multidisciplinary teams in the current clinical practice of lung cancer surgery. A better understanding regarding a series of effective and simple risk factors will provide significant assistance to identify which patients should be considered at high surgical risk. Subsequently, an accurate and personalized treatment scheme based on these putative prognostic factors will be vital to prevent the morbidity risk, enhance the surgical tolerability, and limit the unfavorable survival. Each contributing author has a particular interest in the selected hot subjects of modern perioperative medicine in lung cancer surgery, including body composition, host immune-nutritional status, tumor spread through air spaces (STAS), conversion to thoracotomy, enhanced recovery after surgery (ERAS), elderly health care, protective ventilation, intraoperative fluid management, digital pleural drainage technology, lung ultrasonography, endoscopic intervention, etc. They have given their influential opinions by literature review, personal expertise, and outcome discussion from their works. In this way, this book can help the readers get a comprehensive scenario about the current research highlights of perioperative risk factor analysis and appropriate treatment options in lung cancer surger
