Raman Characterization of Plastics: A DFT Study of Polystyrene
This study addresses this gap by using theoretical calculations to generate ab initio spectra for polystyrene, a reference material. The aim is to explain the origins of the spectral peaks and their consistency across various compositions and structures using linear ordered polymeric and finite amorphous models. The CRYSTAL package is employed to obtain full Raman spectra based on a careful benchmark of computational settings. While some peaks are present across all spectra and can serve for calibration, others exhibit structure-dependent behavior, enabling polymer identification. We conclude that Raman spectroscopy is a w...

Deep learning-based optimization of field geometry for total marrow irradiation delivered with volumetric modulated arc therapy
CONCLUSIONS: The generated field geometries were clinically acceptable and adequate, even for an MP with high level of expertise in TMI/TMLI. Incorporating the knowledge of the MPs into the development cycle was crucial for optimizing the models, especially in this scenario with limited data.PMID:38634859 | DOI:10.1002/mp.17089 (Source: Health Physics)

It's OK to move! Effect of a brief video on community confidence in activity despite back pain: A randomised trial
CONCLUSION: Participants who viewed a brief video intervention reported a very small difference in confidence to become active despite low back pain, compared with no intervention. The difference may lack clinical relevance.PMID:38635937 | DOI:10.2519/jospt.2024.12412 (Source: Health Physics)

Digital Screen Time and the Risk of Female Breast Cancer: A Retrospective Matched Case-Control Study
CONCLUSION: Our findings suggest that heavy exposure to HEV blue light emitted from mobile phone screens at night might constitute a risk factor for promoting the development of breast cancer, but further large-scale cohort studies are warranted.PMID:38628888 | PMC:PMC11016821 | DOI:10.31661/jbpe.v0i0.2310-1678 (Source: Health Physics)

A Framework for Neonatal Prematurity Information System Development Based on a Systematic Review on Current Registries: An Original Research
CONCLUSION: To the best of our knowledge, this is a comprehensive study that has systematically reviewed prematurity-related registries. Since there are international standards to develop new registries, the proposed framework in this article can be beneficial too. This framework is essential not only to facilitate the prematurity registry design but also to help the collection of high-value clinical data necessary for the acquisition of better clinical knowledge.PMID:38628889 | PMC:PMC11016830 | DOI:10.31661/jbpe.v0i0.2105-1345 (Source: Health Physics)

Toxicity evaluation of dose-escalation in hypofractionated regional nodal irradiation for breast cancer: a retrospective study
CONCLUSIONS: Patients who received dose-escalation in hypofractionated RNI face a higher risk of developing lymphedema and shoulder stiffness compared to those who received standard-dose hypofractionated RNI. Therefore, it is crucial to implement close and frequent monitoring for early detection, along with timely rehabilitation interventions for these patients.PMID:38631540 | DOI:10.1016/j.ijrobp.2024.04.014 (Source: Health Physics)

Examining Ableism Through the Physical Activity Experiences of Blind and Visually Impaired Women
This study examined how ableism influences blind and visually impaired women's experiences accessing and engaging in exercise, physical activity, and sport.METHODS: Ten women between the ages of 27 and 45 years completed a one-on-one audio-recorded virtual interview where they reflected on the meaningfulness of their exercise, physical activity, and/or sport experiences, as well as described any experiences related to direct, indirect, systemic, or internalized ableism within or when attempting to access those physical activity experiences. The interview transcripts were analyzed using reflexive thematic analysis.FINDINGS:...
