RESUMO
Quantum entanglement serves as an essential resource across various fields, including quantum communication, quantum computing, and quantum precision measurement. Quantum microscope, as one of the significant applications in quantum precision measurement, could bring revolutionary advancements in both signal-to-noise ratio (SNR) and spatial resolution of imaging. Here, we present a quantum microscopy system that relies on a fully fiber-integrated high-performance energy-time entangled light source operating within the near-infrared II (NIR-II) window. Complemented by tailored real-time data acquisition and processing software, we successfully demonstrate the quantum imaging of a standard target, achieving a SNR of 131.51 ± 6.74 and a spatial resolution of 4.75 ± 0.27 µm. Furthermore, we showcase quantum imaging of cancer cells, unveiling the potential of quantum entanglement in biomedical applications. Our fiber-integrated quantum microscope, characterized by high imaging SNR, instantaneous image capture, and analysis capabilities, marks an important step toward the practical application in life sciences.
RESUMO
BACKGROUND: Evening-type and insomnia symptoms are significantly related to each other and independently associated with depressive symptoms, yet few studies have examined the potential interaction between these two conditions. Therefore, we aimed to examine the associations of evening-type and insomnia symptoms with depressive symptoms among Chinese youths, with a specific focus on the joint effects of the two conditions on depressive symptoms. METHODS: Participants aged between 12 and 25 were invited to participate in an online survey from December 15, 2022, to May 26, 2023. Multivariate logistic regression models and additive interaction models were used to examine the independent and joint effects of chronotypes and insomnia symptoms on depressive symptoms, respectively. RESULTS: Of the 6145 eligible youths, the prevalence of evening-type and insomnia symptoms were 24.9 % and 29.6 %, respectively. Both evening-type (adjusted OR, [AdjOR]: 3.21, 95 % CI: 2.80-3.67) and insomnia symptoms (AdjOR: 10.53, 95 % CI: 9.14-12.12) were associated with an increased risk of depressive symptoms. In addition, the additive interaction models showed that there is an enhanced risk of depression related to interaction between evening-type and insomnia symptoms (relative excess risk due to interaction, [RERI]: 11.66, 95 % CI: 7.21-16.11). CONCLUSIONS: The present study provided additional evidence demonstrating the presence of interaction between evening-type and insomnia symptoms, which can lead to a higher risk of depressive symptoms. Our findings argue the need for addressing both sleep and circadian factors in the management of depressive symptoms in young people.

Objective@#To explore the intrinsic mechanism of emotional intelligence and trait anger in the association between childhood psychological abuse and aggressive behavior among middle school students,and to provide a theoretical basis for intervention of aggressive behaviors.@*Methods@#By using the multi-stage stratified random sampling method, 2 458 middle school students in Guizhou Province were selected, and group tests were carried out using psychological abuse scale, attack behavior scale,emotional intelligence scale and characteristic anger scale.@*Results@#Agressive behavior, trait anger and emotional intelligence differed significantly by gender(t=2.19,5.12,-2.34,P<0.05), and there were significant differences in aggressive behavior, psychological abuse, emotional intelligence and trait anger among middle school students of different student origins by residence(t=-18.77,-6.04,9.10,-9.94,P<0.05). Childhood psychological abuse (r=0.41), temperamental trait anger (r=0.52) and reactive trait anger (r=0.49) were significantly positively correlated with aggressive behavior(P<0.05). Emotional intelligence was significantly negatively correlated with aggressive behavior (r=-0.33, P<0.05). The test of multiple mediation effects showed that emotional intelligence, temperamental trait anger and reactive trait anger played multiple mediation roles between psychological abuse and aggressive behavior in childhood.@*Conclusion@#Childhood psychological abuse could not only directly affect the aggressive behavior of middle school students, but also further affect the aggressive behavior through emotional intelligence and trait anger. Emotional intelligence and idiosyncratic anger are important internal mechanisms by which childhood psychological abuse affects aggressive behavior.
