Here we show how surface-enhanced Raman spectroscopy (SERS) features can be fine-tuned in optically active substrates made of layered materials. To demonstrate this, we used DNA-assisted lithography (DALI) to create substrates with silver bowtie nanoparticle-aperture pairs and then coated the samples with rhodamine 6G (R6G) molecules. By varying the spacing between the aperture and particle layer, we were able to control the strength of the interlayer coupling between the plasmon resonances of the apertures and those of the underlying bowtie particles.

The corpus-semantic models are trained on word segments, and decoding is carried out with word vectors that are composed of these segments. We tested several alternative vector-space models using different segmentations: no segmentation (whole word), linguistic morphemes, statistical morphemes, random segmentation, and character-level 1-, 2- and 3-grams, and paired them with recorded MEG responses to multimorphemic words in a visual word recognition task.

Methods: Specialists from 28 countries were invited to a survey via professional organisations.
Background: The ability to self-advocate or have a say in one's care is integral to personalised care after acquired brain injury (ABI). This study aimed to understand what constitutes self-advocacy and associated barriers and facilitators throughout hospital transitions and into the community.
Method: Qualitative methodology was employed with semistructured interviews conducted with 12 people with ABI and 13 family members.
