Development of airborne hemispheric spectrometer
No full textA new concept of hyperspectral instrument is presented. Novel design of hyperspectral skydome allows retrieval of atmospheric constituents and properties from a snapshot of spectral solar radiation over entire sky, regardless of platform motion either on ground or aircraft. Design and description of subsystems of the instrument are given followed by preliminary tolerance analysis, whose results are to be added in the retrieval algorithm along with hardware specifications. Extended application of the hyperspectral skydome is being carried out filling in the gap in the imaging spectrometry
Hommage à M. Choi Seung-Un
No full textIl y a un an jour pour jour, le 13 octobre 2013, M. Choi Seung-Un nous quittait. Le jour anniversaire de sa disparition est l’occasion pour le Réseau des études sur la Corée de lui rendre un modeste hommage. Nous exprimons à sa veuve notre profonde sympathie en ce jour de souvenir. J’ai eu personnellement la chance et l’honneur de côtoyer M. Choi en tant qu’étudiant, puis en tant que collègue pendant dix ans à l’université Paris Diderot. M. Choi a connu et accompagné presque tous les stades d..

Periodontitis is a complex disease that involves interactions among three main features - microbial challenge, the host immune response, and environmental and genetic risk factors - in its pathogenesis. Although periodontitis has been regarded as the result of hyperimmune or hyperinflammatory responses to plaque bacteria, recent studies indicate that periodontal pathogens are rather poor activators and/or suppressors of the host immune response. This raises the question of how periodontal pathogens cause inflammation. To resolve this issue, in the present review we propose that bacterial invasion into gingival tissue is a key event in the initiation of periodontitis and that the persistence of these bacteria within host tissue results in chronic inflammation. In support of this hypothesis, we present the ways in which microbial, environmental and genetic risk factors contribute to bacterial invasion. It is hoped that the current model will instigate active discussion and new research to complete the puzzle of this complex disease process.OAIID:oai:osos.snu.ac.kr:snu2014-01/102/0000025661/5ADJUST_YN:NEMP_ID:A075701DEPT_CD:852CITE_RATE:2.466DEPT_NM:치의과학과SCOPUS_YN:YCONFIRM:YN
V-band MMIC oscillator array
No full textA y-band strongly-coupled single-chip MMIC oscillator array is presented. For wide bandwidth and easy biasing to push-pull type oscillators, modified 2-port microstrip parasitic coupled antennas are employed. When measured in a closed oversized waveguide, the MMIC oscillator array with two 2-port antennas and four oscillators radiated an output power of 4.4 dBm with excellent spatial power combining efficiency of 93% at 58.59 GHz.N
Closest pair queries in spatio-temporal databases
No full textIn recent years, spatio-temporal databases have been studied intensively. This paper proposes how to process k closest pair queries in spatio-temporal databases for the first time. A spatio-temporal k closest pair query continuously searches the k closest pairs between a set of spatial objects and a set of moving objects for a specified time interval of the query. To maintain the order of the kclosest pairs, we use a time function that can represent the change in distance between a spatial object and a moving object as time passes. For efficient processing of k closest pair queries, we present an event-based structure, instead of a simple split list structure to avoid unnecessary computations, along with a distance bound used to prune unnecessary node accesses. Our event-based method is 9 to 43 times faster, compared to a method using a simple split list structure. Also, our event-based structure can be applied to process spatio-temporal k nearest neighbor queries. In various experiments, our event-based approach is 11 to 46 times faster than an existing approach for processing spatio-temporal k nearest neighbor queries
