Time-resolved sum-frequency generation is an established tool to investigate ultrafast vibrational dynamics with surface and interface specificity. We present an extension of the technique to the regime of electronic transitions based on a compressed white light continuum. It is used to probe the non-equilibrium dynamics of excitonic resonances in the non-centrosymmetric oxide ZnO, where we dem...

The recent progress made in the development of electrochemical methods for microRNA (miRNA) detection is presented. This progress is conceived to be largely due to the invention of novel assay methodologies and the use of various bioreagents and nanostructures. These enable a rigorous control over the sensing interface, provide enormous signal amplifications and single-base mismatch specificity...

background and objective: according to the fact that neonatal infection is a challenging diagnosis field, several studies have tried to test sensitivity and specificity of diagnostic tests. this study was conducted to evaluate the sensitivity and specificity of procalcitonin (pct) as a single early marker of neonatal sepsis. materials and methods: in this study, 150 neonates admitted to nicu an...

Despite progresses in the last decades in the comprehension of specificity, the core questions of how it is encoded in the grammar and how it determines the syntax/semantics interplay remain open. This paper describes a new perspective for tackling these questions based on a fine grained syntax/semantics for noun phrases. The proposed format should be able to account for the variety of specific...

Using an experimental task in which lay persons were asked to distinguish between 30 images of melanomas and common mimics of melanoma, we compared various training strategies including the ABC(D) method, use of images of both melanomas and mimics of melanoma, and alternative methods of choosing training image exemplars. Based on a sample size of 976 persons, and an online experimental task, we...
