Non-utopian optical properties computed of a tomographically reconstructed real photonic nanostructure.

State-of-the-art computational methods combined with common idealized structural models provide an incomplete understanding of experimental observations on real nanostructures, since manufacturing introduces unavoidable deviations from the design. We propose to close this knowledge gap by using the real structure of a manufactured nanostructure as input in computations to obtain a realistic comparison with measurements on the same nanostructure. We demonstrate this approach on the structure of a real inverse woodpile photonic bandgap crystal made from silicon, as previously obtained by synchrotron X-ray imaging.

Food insecurity and other barriers to adherence to a gluten-free diet in individuals with coeliac disease and non-coeliac gluten sensitivity in the Netherlands: a mixed-methods study.

Objectives: To determine the prevalence of food insecurity among individuals with coeliac disease (CeD) and non-coeliac gluten sensitivity (NCGS) in the Netherlands and explore its association with diet quality and other barriers to adherence to a gluten-free diet.

Design: Mixed-method design comprising a survey and semistructured interviews.

Setting: An online survey was distributed through social media accounts and the newsletter of the Dutch Association for Celiac Disease.

Clinical and Humanistic Burden of IgAN in Adult Patients: A Global Real-World Survey.

Background: Immunoglobulin A nephropathy (IgAN) is a chronic, progressive kidney disease in which proteinuria, reduced estimated glomerular filtration rate (eGFR), pain and fatigue are common. How symptoms interact and impact patient quality of life (QoL) in real-world practice is poorly studied. This study investigated how patient and physician symptom perceptions differ and how proteinuria and eGFR correlate with pain, fatigue, and QoL in adult IgAN patients.

The Association of a Vegan Diet during Pregnancy with Maternal and Child Outcomes: A Systematic Review.

With the increasing prevalence of pregnant women adhering to a vegan diet, gaining insight into their nutritional intake and its association with maternal and fetal outcomes is essential to providing recommendations and developing guidelines for general practice. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review of the available scientific literature in Medline, Embase, and Cochrane was conducted in January 2024. : The titles and abstracts of 2211 unique articles were screened.

Interference between multipolar two-photon transitions in quantum emitters near plasmonic nanostructures.

In the vicinity of plasmonic nanostructures that support highly confined light fields, spontaneous emission processes, such as two-photon spontaneous emission (TPSE), exhibit higher-order multipolar emission pathways beyond the dipolar one. These multipolar emission channels occur simultaneously and can interfere with each other. We develop a novel framework that computes these interference effects for TPSE of a quantum emitter close to an arbitrary nanostructure.
