Strong coupling between nanocavities and single excitons at room temperature is important for studying cavity quantum electrodynamics. However, the coupling strength is highly dependent on the spatial light-confinement ability of the cavity, the number of involved excitons, and the orientation of the electric field within the cavity. By constructing a hybrid cavity with a one-dimensional photonic crystal cavity and a plasmonic nanocavity, we effectively improve the quality factor, reduce the mode volume, and control the direction of the electric field using Bloch surface waves.

Background: The common APOE2/E3/E4 polymorphism, the strongest risk factor for Alzheimer's disease (AD), is determined by two-site haplotypes at codons 112 (Cys>Arg) and 158 (Arg>Cys), resulting into six genotypes. Due to strong linkage disequilibrium between the two sites, 3 of the 4 expected haplotypes (E2, E3, E4) have been observed and extensively studied in relation to AD risk. Compared to the most common haplotype of E3 (Cys112 - Arg158), E4 (Arg112 - Arg 158) and E2 (Cys112 - Cys158) haplotypes are determined by a single-point mutation at codons 112 and 158, respectively.

TBI is the leading cause of mortality in young adults and causes a huge socioeconomic burden. Improving outcomes in these patients would be a significant public health benefit.

Background: Vitamin D deficiency is linked with the risk of developing dementia and Alzheimer disease. There is paucity of data on serum vitamin D level among patients from tropical countries such as Ethiopia. The objective of this study is to determine the prevalence of vitamin D deficiency and associated factors among Alzheimer disease and related dementia patients in Ethiopia.

Background: The Uniform Data Set (UDS) neuropsychological battery, administered across Alzheimer's Disease Centers (ADC), includes memory tests but lacks a list-learning paradigm. ADCs often supplement the UDS with their own preferred list-learning task. Given the importance of list-learning for characterizing memory, we aimed to develop a harmonized memory score that incorporates UDS memory tests while allowing centers to contribute differing list-learning tasks.
