Parents' WhatsApp coping resources in the context of ongoing political conflicts: An ecological exploration

American Journal of Community Psychology, EarlyView.
Abstract Mobile technologies have become significant resources for crisis communication and social support in recent years. However, despite empirical evidence pointing to the centrality of these technologies for parenthood in everyday life, it is yet unknown how parents' coping resources play a role in the digital environment.

Enhancement of Modulation Bandwidth for VLC Utilizing Green Mini‐LED Light Source

Advanced Physics Research, EarlyView.
This paper investigates three sizes of green Mini‐LEDs for visible light communication, focusing on modulation bandwidth and the impact of atomic layer deposition (ALD) sidewall passivation. ALD significantly enhances bandwidth (up to 21.6%), confirming suppression of nonradiative recombination.

Legal and ethical considerations around the use of existing illustrations to generate new illustrations in the anatomical sciences

Anatomical Sciences Education, Volume 18, Issue 3, Page 289-300, March 2025.
Abstract It is likely existing anatomical illustrations are often used as the basis for new illustrative works, given not all illustrators have access to human tissues, bodies, or prosections on which to base their illustrations. Potential issues arise with this practice in the realms of copyright infringement and plagiarism when authors are seeking to

Off‐Grid Solar Systems: An Experimental Work and Systematic Techno‐Economic Analysis

Energy Science &Engineering, EarlyView.
In the study mentioned above, experimental monitoring and economic evaluation of two off‐grid PV systems were conducted using a low‐cost data logger. The results suggest that basic DC systems are economically feasible compared to grid power, but that AC systems require further cost‐cutting to achieve financial viability.
