Summary: This study demonstrates that aberrations of metalenses should be described in terms of wave optics and not ray tracing, using intensity-based moments and associated parameters. The research shows differences in aberrations of metalenses under axial and non-axial illuminations, helping to identify parameters most prone to induce changes in beam shapes.

Summary: This study aimed to investigate how different baseline states of mind affect the diurnal patterns of salivary stress biomarkers. The results showed that cortisol and alpha-amylase levels were highest on stressful days and lowest on relaxing days, while chromogranin A levels showed the opposite pattern. The study also found that mindfulness practice had different effects on these biomarkers compared to a general relaxed state of mind.

Summary: The interconnectedness of stock markets and spillover effects play a crucial role in asset pricing, portfolio allocation, financial stability, and risk management. This research examines the spillover effects between the four moments of return distributions in CESEE stock markets. The study finds that tracking all spillover effects is challenging and higher moments spillovers have significant implications for individual markets.

Summary: Determination of corticosterone level in rabbit saliva has advantages of non-invasiveness, welfare preservation, and reliable reflection of the animal's state. This study aimed to determine the diurnal rhythm of corticosterone concentration in domestic rabbit saliva. Results showed a significant increase in corticosterone levels between 12:00 and 15:00, displaying a diurnal rhythm. There was no statistically significant difference in individual rabbit saliva corticosterone concentrations.

Summary: Psychological resilience is associated with diurnal salivary cortisol levels in young adults. A high burden of early adversity may disrupt the physiological stress system, while psychological health may be associated with more normative cortisol levels when adversity is low.

Summary: The spatial evolution of statistics of group-focused waves was studied in this research using laboratory experiments. It was found that the skewness and kurtosis of the waves increased during the focusing process and returned to their initial values during the wave breaking and defocusing process.

Summary: Using hedge fund data, we estimate transition matrices for analyzing the mobility properties of skewness, kurtosis, and joint transitions. These matrices provide probabilistic structures of the higher moments individually and jointly. We also apply various indices to analyze the dynamics and validate our findings using Probit models. Our results show a high level of mobility towards non-normality in both investment strategies and the sector as a whole, with only a limited number of strategies maintaining normality in the joint framework.

Summary: This study proposes a new single-stage technique for creating functional surfaces on machined components through a powder mixed EDM process. A comparative analysis of surfaces generated by MoS2 powders of two different sizes, 40 μm (μP) and 90 nm (nP), mixed into the dielectric of EDM is explored. The input parameter chosen is current (Ip), and its effect on Rq, Rsk, Rku, recast layer thickness (RCLT), and EDS analysis of AISI 304 machined surface is assessed. The results show that the Rq increases proportionally with the rise in Ip for both μP and nP mixed dielectrics. At smaller magnitudes of Ip, a unique combination of negatively skewed and positively kurtotic surfaces are generated in both μP and nP mixed dielectrics. The RCLT increases with increasing Ip magnitudes, and the deposition of MoS2 on the machined surface is observed through EDS profiles.

Summary: This study aimed to investigate the diurnal variation in salivary progesterone levels during the menstrual cycle among Indian women. A longitudinal study was conducted with a small sample size of 31 fertile Indian women, and it was found that there was a significant diurnal variation in progesterone levels across the menstrual cycle, with higher levels in the morning.

Summary: Saliva composition has diurnal variations, which are not affected by citric acid stimulation. The variation characteristics of male and female under resting state and acid stimulation are basically the same, with the trend of salivary alpha-amylase activity being opposite to that of cortisol.

Summary: Despite the COVID-19 pandemic discouraging travel, the number of visitors to easily accessible forests near cities is increasing in Korea. This study explored the relationship between stress, perceived restorativeness, forest recreation motivation, and the mental well-being of forest users. The findings revealed a negative correlation between stress and perceived restorativeness, forest recreation motivation, and mental well-being. Additionally, perceived restorativeness and forest recreation motivation were positively correlated with mental well-being. The study suggests that reducing stress among forest users can have direct or indirect effects on perceived restorativeness, forest recreation motivation, and mental well-being.

Summary: This study analyzed the preference and mental restoration of different road settings in Chinese classical gardens. The findings showed that the majority of visitors felt that the road settings in these gardens provided psychological recovery. Factors such as nature, culture, space, refuge, and serenity were found to be important predictors for both mental restoration and preference.

Summary: The purpose of this study is to investigate the influence of forest conservation activities on the physical and psychological wellbeing of participants. The experiment involved 61 participants who engaged in different activities in a forest near an urban area. The results showed that the activities had minimal impact on the musculoskeletal system and were of light intensity. Psychological evaluation indicated a significant increase in positive emotions and a decrease in negative emotions. These findings suggest that low-intensity forest conservation activities have positive effects on the physical and psychological wellbeing of participants.

Summary: This study aimed to investigate the physiological and psychological responses of patients with gambling disorder (GD) to nature therapy. The results showed that exposure to nature-based sounds significantly reduced oxyhemoglobin concentrations in the prefrontal cortex, increased comfort and relaxation, and decreased negative emotions and overall mood disturbance. Therefore, nature sounds can induce physiological relaxation and positive responses among individuals with GD.

Summary: This study investigated the physiological and psychological responses of 27 young females to viewing waterfall and urban images. The results showed that viewing the waterfall image increased sympathetic nervous activity, provided comfortable and relaxed impressions, and improved mood states. In conclusion, visual contact with a waterfall image activated sympathetic nervous activity and evoked positive moods and feelings.
