Femtosecond Laser Assisted Chemical Ionization Mass Spectrometry: Toward Sub-ppq Detection Limits for Organic Molecules.

Ultrasensitive analysis of organic molecules is crucial for various fundamental research and applications. State-of-the-art techniques for this purpose can achieve detection limits of several hundred ppq (parts-per-quadrillion), while a higher sensitivity is pursued constantly. To achieve this goal, we develop femtosecond laser assisted chemical ionization for mass spectrometry.

The Association Between the Impact of COVID-19 and Internalizing Problems Among Children and Adolescents with ADHD: The Moderating Role of Parental Anxiety.

Previous research has identified an increase in internalizing problems during the COVID-19 pandemic in children and adolescents with attention-deficit/hyperactivity disorder (ADHD). Additionally, it has been observed that parents of children with ADHD had elevated levels of anxiety during the pandemic. The current study aimed to longitudinally assess whether the impact of COVID-19 was associated with internalizing problems in children and adolescents with ADHD during the middle (Time 1-Spring 2021 [T1]) and end (Time 2-Fall/Winter 2022 [T2]) of the pandemic, and whether parental anxiety moderated this relationship over time.

Usability of an eHealth sleep education intervention for university students.

Background: It has been estimated that more than one-third of university students suffer from insomnia. Few accessible eHealth sleep education programmes exist for university students and of the ones that do exist, fewer were developed using a user-centred approach, which allows for student input to be systematically collected and utilized to provide students with a programme that they consider to be easy to use and implement and to be effective. () is a four-session eHealth sleep education programme designed for youth but previously only evaluated in younger adolescents (ages 14-18 years).

Examining the role of the visuospatial sketchpad in children's math calculation skills using Baddeley and Hitch's model of working memory.

Math difficulties (MDs) occur in about 3-7 % of children and have been associated with academic, health, and occupational challenges. To date, findings about the role of working memory in MDs have been conflicting. The Automated Working Memory Assessment Battery (AWMA), which assesses all components of Baddeley and Hitch's model of working memory, was used to investigate which component of the model was most related to math calculation skills in elementary-school children.

Understanding the unique and common perspectives of partners engaged in knowledge mobilization activities within pediatric pain management: a mixed methods study.

Background: Knowledge mobilization (KM) is essential to close the longstanding evidence to practice gap in pediatric pain management. Engaging various partners (i.e.
