Sub-cycle dynamics in two-color high-harmonic generation from laser-produced plasmas.

We present high-order harmonic generation (HHG) in laser-produced aluminium and tin plasmas driven by a two-color field with orthogonal polarization, leading to the generation of both odd and even harmonics. We shape the effective drive field with sub-cycle resolution by controlling the phase between the fundamental wave and its second harmonic. The shape of the drive field influences the electron trajectories of the various harmonics generated in these plasmas.

Exploring barriers and facilitators to addressing hazardous alcohol use and AUD in mental health services: a qualitative study among Dutch professionals.

Background: Hazardous alcohol use and alcohol use disorder (AUD) are highly prevalent among clients in mental health services, yet significant gaps remain in the adequate assessment of alcohol use and provision of appropriate alcohol interventions. The aim of this study was to conduct an exploration of (i) alcohol intervention elements used in mental health services and (ii) professionals' reported barriers and facilitators in identifying and intervening with hazardous alcohol use and AUD.

Methods: Qualitative data were obtained by conducting semi-structured interviews among a purposive sample of 18 professionals from 13 different Dutch mental health services organizations (i.

An empirically based typology of temporary alcohol abstinence challenge participants using latent class analysis.

Introduction: Identifying subgroups of Temporary (alcohol) Abstinence Challenge (TAC) participants may offer opportunities to enhance intervention effectiveness. However, knowledge about such subgroups is missing. This study aimed to (i) describe a TAC population; (ii) identify subgroups of participants based on determinants of changes in drinking behaviour; and (iii) characterise subgroups in terms of sociodemographic and other characteristics.

Effectiveness of a self-help guide during a temporary alcohol abstinence challenge: a randomized controlled trial.

Background: The popularity of temporary abstinence challenges (TACs) concerning alcohol consumption is increasing. Support is found to be essential for participants to help them get through a challenge. This study aimed to evaluate the additional effect of a self-help guide, based on health behaviour theories and behaviour change techniques, on (i) successful completion of a TAC and (ii) changes in drinking refusal self-efficacy (DRSE), behavioural automaticity, craving, and alcohol consumption.

Transition to Motherhood: Adverse Childhood Experiences, and Support from Partner, Family and Friends.

Background: The complex identity changes women have to go through to become mothers makes it a challenging transitional period. Especially, mothers who have experienced childhood adversity (ACEs) may be vulnerable to poor adjustment to motherhood. However, support from a partner, family and friends can act as a buffer to cope with this challenging transitional period.
