RESUMO
This manuscript presents a comprehensive study on the assembly of microchips using fluidic self-assembly (FSA) technology, with a focus on optimizing the spacing between binding sites to improve yield and assembly. Through a series of experiments, we explored the assembly of microchips on substrates with varying binding site spacings, revealing the impact of spacing on the rate of undesired chip assembly across multiple sites. Our findings indicate a significant reduction in incorrect assembly rates as the spacing increases beyond a critical threshold of 140 µm. This study delves into the mechanics of chip alignment within the fluid medium, hypothesizing that the extent of the alloy's grip on the chips at different spacings influences assembly outcomes. By analyzing cases of undesired assembly, we identified the relationship between binding site spacing and the area of chip contact, demonstrating a decrease in the combined left and right areas of chips as the spacing increases. The results highlight a critical spacing threshold, which, when optimized, could significantly enhance the efficiency and precision of microchip assembly processes using FSA technology. This research contributes to the field of microcomponent assembly, offering insights into achieving higher integration densities and precision in applications, such as microLED displays and augmented reality (AR) devices.
RESUMO
The goal of this study was to evaluate the effects of an online mind-body training (MBT) program on participants' stress, anger, coping strategies, emotional intelligence, resilience, and positive and negative affect. Forty-two healthy women participated in an online MBT program for approximately 8-10 minutes a day for 8 weeks; a control group of 45 healthy women did not participate in the program. Self-report psychological questionnaires were administered before the beginning of the program and at 4 and 8 weeks following its onset. Data from the MBT group and the control group were compared using repeated measures ANOVA and Student's t-tests. Significant time x group interaction effects were found with respect to stress, coping strategies, anger, emotional intelligence, negative affect and resilience. These results demonstrate beneficial effects of the online MBT program and significant improvements in the psychological capabilities of participants compared with the control group. The effects of online MBT program were similar with those of the previous offline MBT in psychological aspects, suggesting further studies for neuroscientific evidence related stress and emotion of online MBT effects.

There has been growing evidence that the serotonin (5-HT) system is important in the regulation of memory and thus might be associated with Alzheimer's disease (AD), while research results on this issue have been inconsistent. The 5-HT system has also been suggested to be responsible for a significant portion of the behavioural aspects of AD. This study aimed to investigate the associations of the 5-HT transporter gene linked polymorphic region (5-HTTLPR) polymorphism with AD and delusional/aggressive symptoms of AD in Korean samples of 65 patients and 43 controls. The 5-HTTLPR polymorphism was neither associated with AD nor with delusional/aggressive symptoms of AD. It was suggested that phenotypic expression of the 5-HTTLPR polymorphism might be varied according to ethnic differences.
