AIM：To evaluate the peripapillary choroidal thickness（PPCT） in Chinese children,and to analyze the influencing ***： PPCT was measured with enhanced depth imaging optical coherence tomography（EDI-OCT） in 70children（53 myopes and 17 non-myopes） aged 7 to 18 y,with spherical equivalent refractive errors between 0.50and-5.87 diopters（D）.Peripapillary choroidal imaging was performed using circular scans of a diameter of 3.4 mm around the optic *** was measured by EDI-OCT in six sectors： nasal（N）,superonasal（SN）,superotemporal（ST）,temporal（T）,inferotemporal（IT）and inferonasal（IN）,as well as global RNFL thickness（G）.RESULTS： The mean global PPCT was 165.49±33.76 μ*** temporal,inferonasal,inferotemporal PPCT were significantly thinner than the nasal,superonasal,superotemporal segments PPCT were significantly thinner in the myopic group at temporal,superotemporal and inferotemporal *** axial length was significantly associated with the average global（β=-0.419,P =0.014）,superonasal（β=-2.009,P=0.049） and inferonasal（β=-2.000,P=0.049） *** other factors（gender,age,SE） were not significantly associated with ***： PPCT was thinner in the myopic group at temporal,superotemporal and inferotemporal *** axial length was found to be negatively correlated to *** need more further studies about the relationship between PPCT and myopia.

This paper is concerned with the second order elliptic problems with small periodic coefficients on a bounded domain with a curved boundary. A two-scale curved element method which couples linear elements and isoparametric elements is proposed. The error estimate is obtained over the given smooth domain. Furthermore an additive Schwarz method is provided for the isoparametric element method.

Various steep-slope devices based on novel structures and mechanisms garnered considerable attention for their potential in ultra-low power logic applications. In this work, a novel steep-slope negative quantum capacitance field-effect transistor(NQCFET)with molybdenum disulfide(MoS2)-integrated gate stack was realized by theoretical analysis and experimental evaluation. By combining the MoS+2 equivalent capacitance model calibrated with experimental results, the NQCFET device model is further *** results demonstrated that the optimized MoS2-integrated NQCFET can achieve a subthreshold swing(SS)of sub-60 mV/dec over a current range of 5 decades, with the minimum SS reaching 29 mV/dec,indicating the remarkable potential of MoS2-integrated NQCFETs for ultra-low power applications.
