Summary: The newly developed algorithm for computing consistent initial values and Taylor coefficients for DAEs offers new possibilities for applying Taylor series integration methods. By formulating the problem as a constrained optimization problem constrained by the derivative array, explicit description of the inherent dynamics is not required, allowing for various Taylor integration schemes to be defined within a general framework. The methods have been successfully tested on examples from multibody systems simulation and a higher-index DAE benchmark from servo-constraint problems.

Summary: Affective phenomena exhibit significant complexity and heterogeneity, affecting individuals differently based on shared experiences and emotions. Traditional affective science tends to treat affect as homogeneous, overlooking the person-specific heterogeneity in affective complexity. Person-specific analyses have shown promise in mapping heterogeneity in affective complexity and uncovering risk pathways for affective problems.

Summary: In the last decade, there has been a significant increase in research on the neural and behavioral effects of hormonal contraceptive use. The focus has shifted from whether hormonal contraceptives matter for the brain and behavior to understanding how, when, and for whom they matter most. This review aims to go beyond a general synthesis of the effects of hormonal contraceptives on cognition and psychopathology, by considering the nature and specificity of these effects. It also highlights promising areas for future research, such as activational and organizational effects of hormonal contraceptive use, individual differences in effects, and correlates of intrauterine device use.

Summary: The neuroscience of hormonal contraceptives is a crucial yet emerging field. Although limited in size and scope, existing studies emphasize the complex effects of hormonal contraceptives on the nervous system, which can vary due to individual differences, contraceptive type and formulation, and timing of use. Neuroscientists can provide individuals with knowledge about the biopsychological effects of hormonal contraceptives through rigorous randomized controlled trials, large-scale studies examining population-level trends, and dense imaging or intensive longitudinal studies assessing individual-level effects.

Summary: This study found that the ways in which parents and adolescents influence each other in everyday life are unique, with heterogeneity existing across different families. Some families showed a reciprocal day-to-day association between parenting and adolescent affective well-being, while others showed either a unidirectional influence or no day-to-day associations. Adolescents' trait levels of environmental sensitivity and neuroticism played a role in the extent to which they were affected by parenting.

Summary: Inhibitory control is a risk factor for externalizing behaviors in adolescents. This study aimed to validate a novel measure of inhibitory control, examine its daily fluctuations, and explore its association with individual differences in externalizing behaviors. The results showed that the novel measure was reliable and valid, and that daily fluctuations in inhibitory control were closely related to individual differences in baseline impulsive behaviors. Personalized analyses also revealed that inhibitory control had a greater influence on the daily networks of adolescents who used substances compared to those who did not. Overall, this research contributes to the field by providing insights into the importance of daily inhibitory control and its adolescent-specific relevance to impulsive behaviors.
