Nighttime meridional neutral wind responses to SAPS simulated by the TIEGCM:A universal time effect

Earth and Planetary Physics 2021年第1期5卷 52-62页

The present work uses the Thermosphere Ionosphere Electrodynamics General Circulation Model(TIEGCM),under geomagnetically disturbed conditions that are closely related to the southward interplanetary magnetic field(IMF),to investigate how the nighttime poleward wind(30°–50°magnetic latitude and 19–22 magnetic local time)responds to subauroral polarization streams(SAPS)that commence at different universal times(UTs).The SAPS effects on the poleward winds show a remarkable UT variation,with weaker magnitudes at 00 and 12 UT than at 06 and 18 *** strongest poleward wind emerges when SAPS commence at 06 UT,and the weakest poleward wind develops when SAPS occur at 00 UT.A diagnostic analysis of model results shows that the pressure gradient is more prominent for the developing of the poleward wind at 00 and 12 ***,the effect of ion drag is important in the modulation of the poleward wind velocity at 06 and 18 *** is caused by the misalignment of the geomagnetic and geographic coordinate systems,resulting in a large component of ion drag in the geographically northward(southward)direction due to channel orientation of the SAPS at 06 and 18 UT(00 and 12 UT).The Coriolis force effect induced by westward winds maximizes(minimizes)when SAPS commence at 12 UT(00 UT).The centrifugal force due to the accelerated westward winds shows similar UT variations as the Coriolis force,but with an opposite effect.

Cold ions of plasmaspheric origin have been observed to abundantly appear in the magnetospheric side of the Earth's magnetopause. These cold ions could affect the magnetic reconnection processes at the magnetopause by changing the Alfvén velocity and the reconnection rate, while they could also be heated in the reconnection layer during the ongoing reconnections. We report in situ observations from a partially crossing of a reconnection layer near the subsolar magnetopause. During this crossing, step-like accelerating processes of the cold ions were clearly observed, suggesting that the inflow cold ions may be separately accelerated by the rotation discontinuity and slow shock inside the reconnection layer.

The present paper investigates the asymmetrical variability of the location of the north and the south equatorial ionization anomaly(EIA) crests in the East-Asian sector,along with their association with simultaneous observations of equatorial electrojet(EEJ) strength,geomagnetic activity index,and solar flux index during the 2002-2003 sudden stratospheric wanning(SSW) *** of these observations indicates the existence of a large-scale quasi 16-day periodic meridional movement in both EIA crests,and also reveals a strong correlation between the quasi 16-day oscillation in geomagnetic latitudes of the EIA crest and EEJ *** latitude of the northern/southern EIA crest and the EEJ strength indicate that obvious synchronous periodic oscillations were in-phase in the northern and southern hemisphere when the SSW *** addition,it is also found that both the EIA crest location and amplitude of the periodic movement of the EIA locations exhibit hemispheric *** amplitude of the periodic movement of the EIA location in the southern hemisphere is larger than that of the northern hemisphere,and the southern EIA crest is further off from the equator than the north *** these asymmetries requires a combination of mechanisms that involve at least trans-equator meridional winds and the position of a sub-solar point;however,potential disturbances in neutral winds associated with the SSW may additionally complicate the equatorial ionospheric dynamics.

作者： shunrong zhang Yue Gao Geriatric department Hangzhou First People’s Hospital

Objective: To clarify whether advanced glycation end products (AGEs) can influence the expression of mitochondrial dynamics related proteins Mfn2 and Fis1 in cultured human aortic endothelial cells(HAECs) in vitro. Methods: AGE-BSA was used as AGEs, purchased primary human aortic endothelial cell line was multiplied, and transferred to different passages for subsequent grouping. According to different concentration of AGE-BSA and different duration of AGE-BSA intervention, concentration gradient and time gradient of AGE-BSA intervention experiments were performed. For concentration gradient experiment, HAECs were divided into 4 groups, the concentrations of AGE-BSA in each group were 0 mg/L,50 mg/L,100 mg/L, and 200 mg/L respectively;for time gradient experiment, HAECs were divided into 5 groups with the same concentration of 100 mg/L AGE-BSA , but the intervention times were 0 hour, 6 hours ,12 hours ,24 hours, and 48 hours respectively. RT-PCR method was used to detect the m RNA expression level of Mfn2 and Fis1 genes, whereas western blot method to detect the protein expression level of Mfn1 and Fis1 genes. All data were compared and analyzed with SPSS 16.0 statistical software package. Results: AGEs can decrease the m RNA and protein expression level of Mfn2 in HAECs concentration –dependently(P<0.05), time-dependent experiment showed the m RNA and protein expression of Mfn2 gene decreased gradually with the prolongation of AGEs intervention time(P<0.05). AGEs increased the expression level of Fis1 protein concentration-dependently (P<0.05), time-dependent experiment showed the m RNA and protein expression level of Fis1 gene was deceased in 6 hours and 12 hours groups(P<0.05) ,but in 24 hours and 48 hours groups the expression level was increased(P<0.05). Conclusion: AGEs can decrease the expression of mitochondrial dynamicsrelated key protein Mfn2 gene, and increase the expression of Fis1 gene in cultured human aortic endothelial cells in vitro, indicating that

当前,传统的群防群治工作出现弱化趋势,社会治安管理模式面临严峻挑战,因此,新形势下推行治安管理社会化具有重要的现实意义。治安管理社会化包括治安活动的组织化、安全服务的市场化、打击犯罪的合作化、城乡管理的均等化、宣传教育的大众化。要实现治安管理社会化必须建立以党政支持为保障的社会化管理机制,探索以市场化运作为方向的治安管理新方法,完善以社区警务为主导的社会化治安防控体系,构建以警务合作为依托的打击违法犯罪新格局,营造以宣传教育为支撑的治安管理社会化环境。
