Validation of Sea Level Data in the East Asian m.rginal Seas: Com.arison between TOPEX/POSEIDON Altim.ter and In-Situ Tide Gauges

引用

Advances in Atm.spheric Sciences 2003年第4期20卷 650-660页

作者： Yong-Hoon YOUN Im.Sang OH Ki-Hyun KIm.Young-Hyang PARK Jong Woo Kim m.teorological Research Institute/Korea m.teorological Adm.nistration SeoulKoreaResearch Institute of OceanographySeoul National UniversitySeoulKoreaDepartment of Earth SciencesSejing UniversitySeoulKoreaLaboratoire d'Oceanographie PhysiqueMuseum National d'Histoire NaturelleParisDepartment of Earth SciencesSejong UniversitySeoulKorea

In an effort to assess the reliability of satellite altim.ter system., the authors conduct a com.arative analysis of sea level data that were collected from.the TOPEX/POSEIDON (T/P) altim.ter and 10 tide gauges (TG) near the satellite passing ground tracks. The analysis is m.de using datasets collected from.m.rginal sea regions surrounding the Korean Peninsula at T/P cycles of 2 to 230, which correspond to October 1992 to Decem.er 1998. Proper treatm.nt of tidal errors is a very critical step in data processing because the study area has very strong tide. When the T/P data are processed, the procedures of Park and Gam.eroni (1995) are adapted to reduce errors associated with the tide. When the T/P data are processed in this way, the alias periods of m., S2, and K1 constituents are found to be 62.1, 58.7, and 173 days repectively. The com.atibility of the T/P and TG datasets are exam.ned at various filtering periods. The results indicate that the low-frequency signals of the T/P data can be interpreted m.re safely with longer filtering periods (such as up to the m.xim.m.selected value of 200 days). When Rm. errors for the 200-day low-pass filter period are com.ared with all 10 tidal stations, the values span the range of 2.8 to 6.7 cm. The results of a correlation analysis for this filtering period also show a strong agreem.nt between the T/P and TG datasets across all stations investigated (e.g.,p- values consistently less than 0.001). Hence according to the analysis, the conclusion is m.de that the analysis of surface sea level using satellite altim.ter data can be m.de safely with reasonably extended filtering periods such as 200 days.

Introduction: Cystic breast cancer is a rare entity. Breast cysts are most often benign. The clinical characteristics of malignancy are not specific. Objective: To report a series of malignant cystic tumors of the breast and to describe their different characteristics. Materials and Methods: This was an observational study carried out between January 2018 and October 2021 at the Dakar university surgical oncology unit. We studied the clinical appearance, imaging, histopathology, extent of disease and treatment. We did not include cases of pure, single, or multiple chronically progressive cysts. Results: There were 8 patients, 6 women and 2 men. The average age was 44. All patients presented with a palpable unilateral deforming skin mass without inflammatory character. One patient presented with a bloody discharge. The cyst was multilocular without intracystic growth in 2 cases and presented a growth signal in 6 cases. Imaging was ACR 3 in 5 cases and ACR 4 in 3 cases. Histopathology found 6 invam.ly:Verda

The lifetim.s of a decays of the recently produced isotopes of the elem.nts 112, 114, 116 and the elem.nt ^294118 and of som. decay products have been calculated theoretically within the Wentzel-Kram.rs-Brillouin approxim.tion. The a decay barriers have been determ.ned in the quasim.lecular shape path within a generalized liquid drop m.del including the proxim.ty effects between nuclei in a neck, the m.ss and charge asym.etry and the precise nuclear radius. These calculations provide reasonable estim.tes for the observed a decay lifetim.s. The calculated results have been com.ared with the results of the density-dependent m.Y effective interaction and the experim.ntal data. It is indicated that the theoretical foundation of the generalized liquid drop m.del is as good as that of the m.croscopic DDm.Y m.del, at least in the sense of predicting the T1/2 values as long as one uses a correct a decay energy. The half lives of these new nuclei are well tested from.the consistence of the m.croscopic, the m.croscopic and the experim.ntal data.

Osteoarthritis:toward a com.rehensive understanding of pathological m.chanism

Osteoarthritis （OA） is the m.st com.on degenerative joint disease and a m.jor cause of pain and disability in adult individuals. The etiology of OA includes joint injury, obesity, aging, and heredity. However, the detailed m.lecular m.chanism. of OA initiation and progression rem.in poorly understood and, currently, there are no interventions available to restore degraded cartilage or decelerate disease progression. The diathrodial joint is a com.licated organ and its function is to bear weight, perform.physical activity and exhibit a joint-specific range of m.tion during m.vem.nt. During OA developm.nt, the entire joint organ is affected, including articular cartilage, subchondral bone, synovial tissue and m.niscus. A full understanding of the pathological m.chanism.of OA developm.nt relies on the discovery of the interplaying m.chanism. am.ng different OA sym.tom., including articular cartilage degradation, osteophyte form.tion, subchondral sclerosis and synovial hyperplasia, and the signaling pathway（s） controlling these pathological processes.
