Article Synopsis
- Researchers have designed and successfully created a slotted photonic crystal with features as small as 40 nm using a standard silicon photonics process.
- The unique design increases the electric field energy by four times compared to traditional slotted photonic crystals by using a specialized unit cell shape that enhances optical energy localization.
- This work paves the way for future development of advanced photonic structures that could improve applications like biosensing and light manipulation on-chip.
Article Synopsis
- Various programs exist to enhance the resilience of healthcare students, but the effectiveness and specific conditions under which they work remain unclear.
- A realist review analyzed 43 articles to identify successful contexts and mechanisms for resilience development, identifying key elements like expert facilitation and validated psychological frameworks.
- The findings suggest that resilience can be fostered in students through reflective skills, metacognitive awareness, and practical application of strategies in flexible, integrated curricula.
is one of the most important pathogens causing bloodstream infections (BSIs) throughout the world. We sought to characterize the phylogroup classification, major human sequence types (STs), antimicrobial resistance, presence of selected antimicrobial resistance and virulence genes, and genetic diversity of isolated from patients with BSIs at the University Hospital in Iran. A total of 100 bloodstream isolates were collected between December 2020 and June 2022.

Background: is an opportunistic hospital pathogen with high antibiotic resistance, and the ability to produce biofilm. This study aimed to investigate epsA, ompA, and bap genes involved in biofilm formation in MDR and XDR clinical isolates of in Khorramabad, Iran.
Methods: In this study, 79 isolates were collected from various samples of the patients admitted to tertiary hospitals in Khorramabad city, Iran, between January and August 2019.
We demonstrate a higher sensitivity detection of proteins in a photonic crystal platform by including a deep subwavelength feature in the unit cell that locally increases the energy density of light. Through both simulations and experiments, the sensing capability of a deep subwavelength-engineered silicon antislot photonic crystal nanobeam (PhCNB) cavity is compared to that of a traditional PhCNB cavity. The redistribution and local enhancement of the energy density by the 50 nm antislot enable stronger light-molecule interaction at the surface of the antislot and lead to a larger resonance shift upon protein binding.
