A long-standing mystery in the study of Field-Aligned Currents(FACs) has been that: how the currents are generated and why they appear to be much stronger at high altitudes than in the ionosphere. Here we present two events of magnetotail FACs observed by the Magnetospheric Multiscale spacecraft(MMs) on 1 st July and 14 th July 2016, to show how the substorm Current Wedges(sCW) were formed. The results show that particles were transferred heading towards the Earth during the expansion phase of *** azimuthal flow formed clockwise(counter-clockwise) vortex-like motion, and then generated downward(upward) FACs on the tailward/poleward side of the distorted field with opposite vorticity on their Earthward/equatorward side. We also analyzed the Region 1 FACs observed by the Earth Explorer swarm spacecraft on 1 st July 2016 and found that they were associated with FACs observed by MMs, although differing by a factor of 10. This difference suggests that either there was the closure of the currents at altitudes above 500 km or the currents were not strictly parallel to B and closed at longitudes away from where they were generated.

世界核心医学期刊文摘（皮肤病学分册） 2005年第10期1卷 46-47页

作者： Rácz E Csikós M Kárpáti s 潘敏 Department of Dermato-Venereology Semmelweis University BudapestHungary

Benign familial chronic pemphigus (Hailey-Hailey disease,HHD) is a rare hereditary condition characterized by development of blisters at sites of friction and in the intertriginous areas. Mutations in the ATP2C1 gene, which encodes the human secretory pathway calcium ATPase 1 (hsPCA1), have been identified as possible causative mutations. studying Hungarian patients with HHD, we found two novel, distinct, heterozygous mutations. In a 65-year-old man with a 41-year history of severe recurrent symptoms, a single nucleotide insertion,1085insA, was detected. In a patient whose symptoms were induced by environmental contact allergens, we found a nonsense mutation, Q506X, in exon 17. Our study further illustrates the diversity of mutational events in the pathogenesis of HHD.

世界核心医学期刊文摘（皮肤病学分册） 2005年第7期1卷 21-21页

Background: Recently, epidermal transglutaminase (TG) has been identified within the papillary IgA granules in dermatitis herpetiformis (DH). Although IgA type autoantibodies to tissue and epidermal TGs are characteristic serological markers for DH, these antibodies do not bind to normal papillary skin structures. Aims: To test the possibility of IgA immune com-plex precipitation within the vessel walls as a first step in the pathogenesis of skin symptoms, we analysed immunoglobulin, complement, and epidermal TG deposition along the vascular system of DH skin. Methods: Punch biopsy specimen were taken from 116 DH patients’ skin,and evaluated for the presence of vascular immune precipitates by direct immunofl uorescence. skin samples from 16 DH patients were also studied for tissue and epidermal TGs. Results: In 74 (64% ) of the 116 DH skin studied, significant vascular staining accompanied the DH-specific granular IgA fluorescence (IgA and C3 in 39 patients; IgA alone in 18; IgA, C3 and IgM together in five; IgM alone in 12). In most cases (92% ), the precipitates were detected in the small vessels of the papillary dermis; however, a subpapillary vascular fluorescence was also observed in a few patients (8% ). skin IgA colocalized with epidermal TG in the vessel walls and within the scattered papillary peri-and intervascular DH bodies. tissue TG did not colocalize either with the immunoglobulins or with the complement precipitates of the dermis. Furthermore, we could not detect keratinocyte TG in the DH bodies nor in the vessel walls. Conclusions: These findings support possible immune complex precipitation in the vessel walls of DH skin and further confirm the significance of epidermal but not tissue TG in the pathomechanism of skin symptoms.

This paper, taking Beiwenquan Town of Beibei, Chongqing as an example, assessed the impacts of land use on ecological health by comprehensive index method, and discussed methodological system of sustainable land use planning based on ecological health. Results indicated that: 1) From 1992 to 2002, land use changes focused on 12 patterns with the total conversion area of 92.11%, which were related to cultivated land, residential and industrial-mining area, and orchard land. Urbanization and economic reconstruction were the leading driving forces. 2) There was obvious difference of the areas of ecotypes driven by land use change in wide valley and mild slope between 1992 and 2002, while there were little or no difference in steep slope and very steep slope. 3) Both of the conditions of ecological health in 1992 and 2002 were sound, and the ecotypes focused on the types of health and sub-health. But, health ecosystem in 1992, with an area of 764.64ha, accounting for 38.51% of the total evaluation area, was better than that in 2002, with an area of 636.10ha, accounting for 34.19% of the total evaluation area. 4) The ecotypes involved into different ranges have already degenerated, due to humankind’s disturbance, while the conditions of ecological health in the same ranges in 1992, regardless of stability and reconstruction, were better than that in 2002. 5) The planning scenario based on ecological health was accorded with the practice condition of Beiwenquan Town: 388.29ha of cultivated land could meet the Beiwenquan demand of food and byproduct; 1045.26ha of forest land area, the Beiwenquan demand of ecological health; and 1004.73ha of the residential and industrial-mining area, the Beiwenquan building demand. 6) sustainable land use planning based on ecological health had higher useful value, because it not only stood to ecological theory, but also satisfied the developmental demand of society and economy.

Wave overtopping at a sea dike was observed using video images during a storm in July 2018 at Rizhao Coast,China.A shore-based video monitoring system was mounted to collect coastal images with a sample frequency of 1 Hz in the beginning 10 min of each hour during daylight.A method to extract the frequency,location,width and duration of individual overtopping events based on the shore-based video monitoring system was developed.A total of 6252 individual overtopping events were detected over a 360m long sea dike during the storm of 10 h in a safe and labor-saving way,enabling a detailed analysis of the temporal and spatial variation of wave *** temporal variation of overtopping duration,frequency and volume is basically in sync with the change of tidal level(R=0.87,0.82 and 0.76,respectively).The increase of wave height increases the overtopping frequency *** found a high correlation between the hourly observed data and the predicted results of two commonly used *** the previous field measurements of overtopping that were limited in a single location,significant spatial variation of overtopping in the alongshore direction is *** overtopping volume varies with a factor of 6 within the range of several wave *** is further revealed that the spatial variation of overtopping is highly correlated with the alongshore variation of surf zone width with a correlation coefficient of *** present study suggests the feasibility of shore-based video monitoring technique to capture the main features of wave overtopping at coastal dikes,providing new possibilities to monitor wave overtopping in the field and to improve prediction tools.
