Hence, identifying the issue of a label requires further information: if collectors knows the date of use, the existence of a watermark and if so which type, and the specific colour, identification will be easier.
But to date, for the existence of many limits of these low-cost techniques, the fabrication of the large-area low-cost high-performance SERS substrate, with tunable gap size, is still critical not only for practical applications of SERS in the chemical/biological sensor, but also in understanding surface plasmonic coupling existing inside the nanogaps.
Perhaps what we learn from Amy Webb's story is that online dating – since those participating have no idea of the authenticity of the people they are communicating with – is the most happenstance-based form of dating in existence.
The filmmaker confirmed the date and existence of the footage, as well as Jones' account of her experience with Richardson to HuffPost.
Also found in Dogon territory are what may be the oldest textile fragments in West Africa (dated to the 11th century), establishing a baseline date for the existence of the narrow-band loom in the region, and the oldest wood sculptures in existence (three have been traced by carbon-14 dating to the 15th 17th century ce).
To date, the existence of the "auxiliary factors" for PrP conversion remains unknown.
Thus, to date the existence of a bona fide d-HSC remains confined to the hematopoietic system.
Up to date, the existence of a subtype with an ETP gene expression signature in adult patients has not yet been investigated.
To date, the existence of CSCs has been demonstrated in AML and CML, in brain and gastrointestinal tumours, and in lung and breast cancer (de Jonge-Peeters et al, 2007).
However, to date, for the existence of many limits for these low-cost techniques, the fabrication of large-area high-performance SERS substrate with sub-10-nm gap size is still critical for the practical applications of SERS.
Many astronomers believed that the observational evidence, although still circumstantial, provided the best argument to date for the existence of black holes.
