Quasi-bound states in the continuum for electromagnetic induced transparency and strong excitonic coupling.

Advancing on previous reports, we utilize quasi-bound states in the continuum (q-BICs) supported by a metasurface of TiO meta-atoms with broken inversion symmetry on an SiO substrate, for two possible applications. Firstly, we demonstrate that by tuning the metasurface's asymmetric parameter, a spectral overlap between a broad q-BIC and a narrow magnetic dipole resonance is achieved, yielding an electromagnetic induced transparency analogue with a 50 μs group delay. Secondly, we have found that, due to the strong coupling between the q-BIC and WS exciton at room temperature and normal incidence, by integrating a single layer of WS to the metasurface, a 37.

Palliative care provision for older people in care homes.

There is a paucity of research in relation to district nurses' (DNs) experiences of palliative care provision in adult care homes (CHs) despite their substantial involvement. The aim of this study was to demonstrate the current involvement of DNs in CHs and identify the potential implications for future practice in providing palliative care in this setting. The findings suggested that even experienced DNs, wanted support and education about when to commence palliative care.

Functional mechanisms and histologic composition of the lingual appendage in the alligator snapping turtle, Macroclemys temmincki (Troost) (Testudines: Chelydridae).

Gross and microscopic examination of the lingual appendages of juvenile and adult alligator snapping turtles, Macroclemys temmincki, shows that it is divided into an anterior horn, a body, and a posterior horn. Lingual appendages of adults usually are more darkly pigmented than those of juveniles and melanocyte distribution is variable, resulting in a mottled appearance. The musculoskeletal components of the hyoid apparatus, presumably responsible for most of the motion displayed by the appendage, are described here.
