Background: Adolescence is a pivotal developmental phase, marked by a high prevalence of mental health issues. The Singapore Youth Epidemiology and Resilience (YEAR) study aims to assess the prevalence of mental health symptoms, sociodemographic risk factors, and the protective role of resilience in a multi-ethnic, Asian school-going adolescent population.
Methods: School-based adolescents aged 11-18 and their parents were invited from a stratified sample of national schools, designed to be demographically representative of the mainstream school-going population.
We will consider a thermostatic system, Sprott B, that is a generalization of the well-known one-parameter Sprott A system. Sprott B contains an explicit periodic solution for all positive values of the parameter a. As for Sprott A, we find dissipative KAM tori associated with time-reversal symmetry and canards in dissipative systems.

Article Synopsis
- The study examines how to best measure the general factor of psychopathology using various statistical models on data from youth ratings in 24 societies.
- Four models were tested: principal axis, hierarchical factor, bifactor, and a simple Total Problem score, analyzing data from over 25,000 youth ages 11-18.
- Findings show that all models yielded similar results, suggesting that the simplest approach (the Total Problem score) is recommended for evaluating youth psychopathology in both clinical and research settings.

Background: Similarities exist between contemporary explanatory models underlying psychosis development, functional somatic symptoms, and health anxiety. The current study aimed to examine the potential interplay between psychotic experiences (and alternate measures of anomalous self-experiences and aberrant attribution of salience) and functional somatic symptoms on the outcome of health anxiety in youths.
Methods: In a prospective general-population birth cohort, the Copenhagen Child Cohort 2000 (CCC2000), data from two time-points were available for 1122 individuals.
