in january 2011, a large number of solar flares were observed. based on the analysis of the geomagnetic storms and solar flares, we compared the geomagnetic storm with the solar flares at the same time. a scatter diagram is used to analyze the different change of solar flares and geomagnetic storms. we can see that the geomagnetic storms and solar flares are related to each other, and the geomagnetic storms can be divided into two groups: the geomagnetic storms during the flare decay and geomagnetic storms during the main flare. the geomagnetic storms during the flare decay are mainly due to the occurrence of electric fields in the interplanetary space and are mainly used for research and analysis of the high-altitude electron physics. some of the geomagnetic storms during the main flare are related to the fluctuations of the solar magnetic field and the geomagnetic storms induced by the electric fields produced by the solar magnetic field. we hope that this study can provide a basic reference data for further analysis of the solar activity and the related space weather and the space environment. level of evidence level ii.
in the process of testing of low-level illumination sources, it is difficult to properly use uniform and stable illuminating light sources because they often contain extraneous light with much different wavelengths. in particular, some leds have very low light energy at the specified wavelengths, as compared with incandescent lamps. on the other hand, the spectral energy distribution of leds may have an abrupt end at the specified wavelengths. it is difficult to determine the spectrum of illumination light using existing technologies. as a result, the system performance often must be tested several times for a set of illumination condition.
background the purpose of this study was to better understand the correlations and trends in the menstrual cycle of the pelvic organ mobility of undergraduate students. purpose this study sought to quantify the pelvic motion of the hip, the waist, the knee, the ankle, and the upper spine for three specific positions of the pelvic floor muscles. materials and methods sixteen undergraduate students in the third trimester of their first year of nursing school were recruited for this study. ultrasound imaging of the pelvic floor musculature was obtained. pelvic floor muscle tone was recorded during three postural conditions: relaxed, contracted, and contracted while actively breathing. a motion capture camera system was used to quantify each posture using a model of the upper spine, hip, waist, and knee. motion was defined using three kinematic elements: hip flexion, knee flexion, and hip extension. three position voids were used to create contact points for each of the upper spine, hip, and lower back. a linear regression analysis was applied to the data and to the average of each position for each participant. results at baseline, the neutral pelvic floor muscle mobility was lower than at the other positions. during relaxed pelvic floor muscle tone, the hip flexion was increased for all participants. in this study, we compare cme yield and its dependence on the occurrence of coronal mass ejections (cmes) with the number of flares produced by the active regions and their association with flare productivity. according to the cme/flare association, major cmes can be categorized into two types: associated cmes and quiet-cmes. in the former, the cme is associated with flare activity. in the latter, it does not show an obvious relation to flaring activity. we found that these two categories of cmes follow similar distributions in the 10 cme-productive active regions studied here. likewise, we found that cme yield (cme rate normalized to the total number of major solar events produced by the regions) and the number of associated flares have a similar distribution. this similarity extends to the size distribution of flare-associated cmes, and to the cme/flare time relation. the fractal dimension of flare-associated cmes is in general greater than that of quiet-cmes, but the difference is small. 5ec8ef588b
