The impact of colloid-solvent dynamic coupling on the coarsening rate of colloidal phase separation.

Phase separation, a fundamental phenomenon in both natural and industrial settings, involves the coarsening of domains over time t to reduce interfacial energy. While well-understood for simple viscous liquid mixtures, the physical laws governing coarsening dynamics in complex fluids, such as colloidal suspensions, remain unclear. Here, we investigate colloidal phase separation through particle-based simulations with and without hydrodynamic interactions (HIs).

Reliability and Validity of the Japanese Version of the Internet Gaming Disorder Scale for Children (IGDS-C).

Aim: The Internet Gaming Disorder Scale is a 9-item screening instrument developed based on the diagnostic criteria for Internet Gaming Disorder (IGD) in the DSM-5. This study aimed to examine the reliability and validity of the Internet Gaming Disorder Scale for children (IGDS-C) in Japanese clinical and nonclinical populations.

Methods: The study included clinical outpatients aged 9-29 with problematic game use and nonclinical adolescents aged 12-18 who played online games at least once a week.

Gender Dysphoria and Related Symptoms in Autism Spectrum Disorder: A Bilingual Review of the Literature.

The association between autism spectrum disorder (ASD) and gender dysphoria (GD) has attracted a great deal of interest among child and adolescent psychiatrists in Japan. In clinical settings, it is common to hear complaints or concerns related to GD from adolescents with ASD. In the past few years, several review articles have been published on ASD and GD.

Heterogeneity of gaming disorder: A clinically-based typology for developing personalized interventions.

Background: The eleventh revision of the International Classification of Diseases (ICD-11) defines the three key diagnostic criteria for gaming disorder (GD). These are loss of control over gaming, gaming as a priority over daily activities, and impaired functioning due to gaming. While this definition has implications for the prevention and treatment of GD, there is significant heterogeneity in the symptoms and etiology of GD among individuals, which results in different treatment needs.
