In ordered magnets, the elementary excitations are spin waves (magnons), which obey Bose-Einstein statistics. Similarly to Cooper pairs in superconductors, magnons can be paired into bound states under attractive interactions. The Zeeman coupling to a magnetic field is able to tune the particle density through a quantum critical point, beyond which a 'hidden order' is predicted to exist.

Objective: Stimulant drug treatment in preschool-age children for attention-deficit hyperactivity disorder (ADHD) as well as the concomitant use of antipsychotic drugs is largely unstudied in terms of longitudinal outcomes. We characterized longitudinal patterns of stimulant drug use in children diagnosed for ADHD and analyzed the mental health disorders leading to add-on therapy with antipsychotics.
Method: The study population comprised of children and adolescents (age: 0-19 years) in the province of British Columbia (BC), Canada, with at least one dispensing for any psychotropic drug between 1997 and 2017 ( = 144,825).

Background: Lebanon has experienced a series of devastating crises that continue to have significant adverse effects on the mental health of parents and their children, especially those who are unemployed, burdened with debt or financial difficulties, and have pre-existing mental health conditions. Accordingly, this study aimed to assess the effect of financial insecurities on parents in Lebanon amid the multiple crises, and the impact of parents' mental health on their children's emotional and behavioral wellbeing.
Methods: A cross-sectional study including 589 parents in Lebanon was performed using convenience sampling of parents of any gender with children aged 4 to 18 from the five Lebanese governorates.

Objective: To identify social vulnerability profiles of transgender people who have experienced intimate partner violence in Brazil and to assess the association with recurrent violence and referrals to support services.
Methods: This was a cross-sectional study of reported cases of violence against transgender people in Brazil (2015-2021) utilizing data from SINAN/DATASUS. Sociodemographic profiles were defined using two-step cluster analysis and associations estimated by means of binary logistic regression, with odds ratios (OR) and confidence intervals (CI).
