In nursing education, virtual reality simulation (VRS) is recognized as an effective learning method as it overcomes limitations in practical training and positively influences learning ability and satisfaction levels. The purpose of this study was to develop VRS for intravenous (IV) injection and investigate how it affects nursing students' academic knowledge, performance confidence, and clinical practice competencies. A quasi-experimental control group pretest and post-test design was used. Participants were nursing students who either received a training system for an IV injection through VRS (experimental group; = 20) or who received an IV arm simulator (control group; = 20). The results revealed significantly higher knowledge (U = 156.5, = 0.024) and clinical performance competency (U = 87.5, = 0.002) with the procedure of using a training system of VRS for IV injection compared to having training via an IV arm simulator. This study verified that VRS for IV injection was more effective than an IV arm simulator for practical training on IV injection. Thus, VRS for IV injection, an effective teaching method used to improve learning ability and satisfaction levels, can be used as a training method in the future.

This paper systematically evaluates saliency methods as explainability tools for convolutional neural networks trained to diagnose glaucoma using simplified eye fundus images that contain only disc and cup outlines. These simplified images, a methodological novelty, were used to relate features highlighted in the saliency maps to the geometrical clues that experts consider in glaucoma diagnosis. Despite their simplicity, these images retained sufficient information for accurate classification, with balanced accuracies ranging from 0.

Disseminating research or evidence-based practice is not straightforward. As more clinical nurses, executive nurse leaders, nurse scientists, and faculty contribute to new knowledge, there is an increasing need to support the processes to publish and disseminate manuscripts to advance healthcare. Nurse administrators and leaders are key influencers and supporters to bolster expertise and resources to publish.

The abrupt drop of resistance to zero at a critical temperature is a key signature of the current paradigm of the metal-superconductor transition. However, the emergence of an intermediate bosonic insulating state characterized by a resistance peak preceding the onset of the superconducting transition has challenged this traditional understanding. Notably, this phenomenon has been predominantly observed in disordered or chemically doped low-dimensional systems, raising intriguing questions about the generality of the effect and its underlying fundamental physics.

Multiconfiguration pair-density functional theory (MC-PDFT) was proposed a decade ago, but it is still in the early stage of density functional development. MC-PDFT uses functionals that are called on-top functionals; they depend on the density and the on-top pair density. Most MC-PDFT calculations to date have been unoptimized translations of generalized gradient approximations (GGAs) of Kohn-Sham density functional theory (KS-DFT).
