Parents play a vital role in mediating children's media use, especially at a young age. We examined the link between the media use of younger children and the media use, attitude toward media, and parenting styles of parents. One thousand and twenty parents of children between 4 and 6 years of age completed a questionnaire on their media use, positive and negative attitudes on media, parenting styles, and the media use of their children. Multigroup structural equation modeling was used to analyze the data. The results showed that there was a significant positive relation between the parent's media time and the child's daytime and nighttime media use. Additionally, the parent's positive attitude toward media use was positively related to the child's daytime media use, but not the child's nighttime media use, while the parent's negative attitude toward media was not associated with the child's daytime and nighttime media use. Further, among the seven parenting styles, material rewards and autonomy were positively associated with the child's daytime media use. Discipline was negatively related to the child's nighttime media use, whereas material rewards were positively associated with the child's nighttime media use. Collectively, the parent's positive attitude toward media use was the strongest predictor of the child's daytime media use, and material rewards were the strongest predictor of the child's nighttime media use. These results can be of significant use to inform policymakers, researchers, and parents regarding the development of parental guidelines on children's media use.

Background: Social media has become a widely used way for people to share opinions about health care and medical topics. Social media data can be leveraged to understand patient concerns and provide insight into why patients may turn to the internet instead of the health care system for health advice.
Objective: This study aimed to develop a method to investigate Reddit posts discussing health-related conditions.

Introduction: Oral nicotine pouches (ONPs) are increasingly prevalent among young people and feature widely within social media content. This study systematically analyzes the most viewed videos on TikTok relating to ZYN (the most popular ONP, manufactured by a subsidiary of Philip Morris International) to understand their content sentiment and patterns, as well as the demographics and potential commercial biases of their creators.
Methods: We used an Apify scraper in July 2024 to collect URLs and metadata for the top 100 most viewed videos on TikTok under the #ZYN hashtag.

The interaction between waves and evolving media challenges traditional conservation laws. We experimentally investigate the behavior of elastic wave packets crossing a moving interface that separates two media with distinct propagation properties, observing the noninvariance of wavelength and frequency. Our experimental setup employs an elastic strip whose local stretching can be dynamically altered by pulling one end at a constant velocity.

We observe divergent temperature-dependent magnetic resonance relaxation behaviors across various brine-saturated porous materials. The paramagnetic and diamagnetic nature of the samples underlies these divergent behaviors. The temperature-dependent trends of the longitudinal T_{1} and transverse T_{2} relaxation times are systematically explained via distinct relaxation-diffusion regimes of Brownstein-Tarr theory.

We present the concept of time-domain bound states in continuum. We show that a rapid judiciously designed temporal modulation of the refractive index in a spatially homogenous medium gives rise to a bound state in time, embedded in a continuum of wave numbers. Mathematically, these bound states in the continuum are closed form solutions of the Maxwell equations in time and one-dimensional space.
