Wideband multiwavelength Brillouin fiber laser with switchable channel spacing.

A multiwavelength Brillouin fiber laser (MBFL) with a switchable channel spacing is demonstrated using a 1.55-µm single-mode AlGaInAs/InP hybrid square-rectangular laser as a seeding source. The scheme employs a highly nonlinear fiber loop with a feedback path to generate a 10-GHz-spacing MBFL.

Perinatal depression: Data-driven subtypes derived from life history and mindfulness and personality.

Background: Perinatal depression is the most prevalent mental disorder during the perinatal period, and research suggests that it presents heterogeneously. We aimed to explore how subtypes of perinatal depression present in terms of multivariate patterns of stable characteristics.

Methods: A cohort study was conducted from March 2016 to March 2018 with Chinese women in the prenatal period (n = 3186).

Profiles and characteristics of clinical subtypes of perinatal depressive symptoms: A latent class analysis.

Aims: To investigate clinically relevant subtypes of perinatal depressive symptoms.

Design: Cross-sectional study.

Methods: A sample of 2,783 women at different prenatal and postnatal periods was recruited between August 2015 - August 2017.

Effect of the interaction between oxytocin receptor gene polymorphism (rs53576) and stressful life events on aggression in Chinese Han adolescents.

Objectives: Accumulating evidence suggests that stressful life events are associated with increased risk for aggressive behavior in adolescents; however, aggressive reactions to life stressors exhibit large individual differences. The present study sought to examine whether the interaction between a single nucleotide polymorphism (SNP [rs53576]) within the oxytocin receptor gene (OXTR) and stressful life events is related to aggression in Chinese Han adolescents.

Methods: A total of 197 Chinese Han adolescents (14-17 years of age) were included in this study.

Predictors of occupational burnout among nurses: a dominance analysis of job stressors.

Aims And Objectives: To quantitatively compare dimensions of job stressors' effects on nurses' burnout.

Background: Nurses, a key group of health service providers, often experience stressors at work. Extensive research has examined the relationship between job stressors and burnout; however, less has specifically compared the effects of job stressor domains on nurses' burnout.

Association between child maltreatment and prospective and retrospective memory in adolescents: The mediatory effect of neuroticism.

The purpose of this study was to examine the relationship between child maltreatment and prospective and retrospective memory in children/adolescents by investigating the mediating role of neuroticism. In total, 662 children/adolescents aged 10-16 years were recruited from a middle school in China, and they completed questionnaires comprising the Childhood Trauma Questionnaire, Prospective and Retrospective Memory Questionnaire, and the Neuroticism subscale of the NEO Five-Factor Inventory. The severity of maltreatment was positively associated with the severity of impairment of memory (prospective and retrospective considered together) in children/adolescents.
