Ground-layer Adaptive Optics for the 2.5 m Wide-field and High-resolution Solar Telescope

The 2.5 m wide-field and high-resolution solar telescope(WeHoST)is currently under developing for solar observations.WeHoST aims to achieve high-resolution observations over a super-wide field of view(FOV)of5′×5′,and a desired resolution of 0.3″.To meet the scientific requirements of WeHoST,the ground-layer adaptive optics(GLAO)with a specially designed wave front sensing system is as the primary consideration.We introduce the GLAO configuration,particularly the wave front sensing scheme.Utilizing analytic method,we simulate the performance of both classical AO and GLAO systems,optimize the wave front sensing system,and evaluate GLAO performance in terms of PSF uniformity and correction improvement across whole FOV.The results indicate that,the classical AO will achieve diffraction-limited resolution;the suggested GLAO configuration will uniformly improve the seeing across the full 5′×5′FOV,reducing the FWHM across the axis FOV to less than0.3″(λ≥705 nm,r0≥11 cm),which is more than two times improvement.The specially designed wave front sensor schedule offers new potential for WeHoST’s GLAO,particularly the multi-FOV GLAO and the flexibility to select the detected area.These capabilities will significantly enhance the scientific output of the telescope.

Scraping therapy for treating the perimenopausal syndrome

Objective:To evaluate the clinical effect of scraping therapy in the treatment of perimenopausal syndrome(PMS).Methods:Thirty recruited PMS subjects were treated with scraping therapy in the Outpatient Department,Acupuncture-Moxibustion Hospital,China Academy of Chinese Medical Sciences,at the areas including Shéntíng(神庭GV24)-Běihuì(百会GV20),Qìhǎi(气海CV6)-Guānyuán(关元CV4),Zǐgōng(子宫EXCA1),Zúsānlǐ(足三里ST36)-Xiàjùxū(下巨虚ST39),Dìjī(地机SP8)-Sányīnjiāo(三阴交SP6),Tàichōng(太冲LR3)-Xíngjiān(行间LR2),Gānshū(肝俞BL18)-Dǎnshū(胆俞BL19),Píshū(脾俞BL20)-Wèishū(胃俞BL21),and Sānjiāoshū(三焦俞BL 22)-Shènshū(肾俞BL 23),with an even reinforcing-reducing method.Before and after treatment,the serum follicle-stimulating hormone(FSH),luteinizing hormone(LH),and estradiol(E_(2)) were tested.And before treatment and at the 4 th week,8 th week,and 12 th week of treatment,the Kupperman index(KI) and menopause-specific quality of life questionnaire(MENQOL) symptom scores were recorded for evaluating the clinical efficacy.Results:Comparing with before treatment,the modified Kupperman symptom scores were all decreased after treatment,the difference was statistically significant(P<0.05);all symptoms were relieved significantly after treatment,the difference was statistically significant(all P<0.05).There was no significant difference in serum E_(2),FSH,and LH levels after treatment(all P>0.05);the total effective rate was 85.71%after the 4 weeks’ treatment,96.42% after the 8 weeks’ treatment,and 96.42% after the 12 weeks’ treatment.Conclusion:Scraping therapy can relieve the PMS symptoms to some extent.It can improve the life quality of PMS subjects.Its influence on the estrogen levels of PMS subjects was not obvious.
