Selfie, which is used to manage impressions online, has garnered a substantial amount of empirical attention in recent years. However, little is known about what factors influence the angle of an individual's selfie. To address this gap, this study examined the main and interactive effects of gender, culture, and age on selfie angles. A total of 1702 users' (M = 31.08 years; 52% males) selfies were selected on dating websites in China and the United States. A three-way ANOVA test and a series of one- simple t-tests were utilized to analyze the data. Results indicated that the main effect of gender on selfie angles was significant. Specifically, compared with males, females tended to take selfies from a more downward angle. More importantly, the three-way interaction effect among gender, culture, and age on selfie angles was significant. Subsequent simple effect analysis indicated that in the young adults' group, the effect of gender x culture was significant. While in the adults' group, there was no significant interactive effect between gender and culture on the selfie angle. These findings indicate that instead of taking selfie angles as pure variations between males and females, selfie angles should be examined and understood within specific cultural contexts and age groups., Author(s): Rong Bai [sup.1] , Lijing He [sup.1] , Sen Li [sup.2] , Rui Xiang [sup.1] , Shufen Xing [sup.1] Author Affiliations: (1) https://ror.org/005edt527, grid.253663.7, 0000 0004 0368 505X, School [...]

Background: Massage robot is considered as an effective physiological treatment to relieve fatigue, improve blood circulation, relax muscle tone, etc. The simple massage equipment quickly spread into market due to low cost, but they are not widely accepted due to restricted massage function. Complicated structure and high cost caused difficulties for developing multi-function massage equipment.Objective: This paper presents a novel massage robot which can achieve tapping, rolling, kneading and other massage operations, and proposes an improved reciprocating path planning algorithm to improve massage effect.Methods: The number of coil turns, the coil current and the distance between massage head and yoke were chosen to investigate the influence on massage force by finite element method. The control system model of the wheeled massage robot was established, including control subsystem of the motor, path algorithm control subsystem, parameter module of the massage robot and virtual reality interface module. The improved reciprocating path planning algorithm was proposed to improve regional coverage rate and massage effect.Results: The influence caused by coil current, the number of coil turns and the distance between massage head and yoke were simulated in Maxwell. It indicated that coil current has more important influence compared to the other two factors. The path planning simulation of the massage robot was completed in Matlab, and the results show that the improved reciprocating path planning algorithm achieved higher coverage rate than the traditional algorithm.Conclusions: With the analysis of simulation results, it can be concluded that the number of coil turns and the distance between the moving iron core and the yoke could be determined prior to coil current, and the force can be controllable by optimizing structure parameters of massage head and adjusting coil current. Meanwhile, it demonstrates that the proposed algorithm could effectively improve path coverage rate during massage operations, therefore the massage effect can be improved. [ABSTRACT FROM AUTHOR]

Summary. The Platelet Function Analyzer (PFA-100® ) was used to measure platelet function in paediatric patients with destructive versus underproduction thrombocytopenia. Closure time (CT) and total volume (TV) measurements with standard 150 μm apertures discriminated between patients with similar platelet counts from 30 to 150 × 109 /l. However, at platelet counts < 30 × 109 /l, a 100-μm aperture (experimental) gave the best assessment of platelet function. TV results could be analysed even when CTs were indeterminate. Further investigations are warranted to more fully understand the relationships among platelet function as measured by the PFA-100® in standard/experimental modes, bleeding and transfusion outcome in thrombocytopenia.
