Side-By-Side Evaluation of Three Commercial ELISAs for the Quantification of SARS-CoV-2 IgG Antibodies

Viruses, 2022
In December 2020, WHO presented the first international standard (WHO IS) for anti-SARS-CoV-2 immunoglobulin. This standard is intended to serve as a reference reagent against which serological tests can be calibrated, thus creating better comparability ...

Revisiting the HPLC-FLD Method to Quantify Paralytic Shellfish Toxins: C3,4 Quantification and the First Steps towards Validation

Toxins, 2022
Paralytic shellfish toxins (PSTs) are a large group of biotoxins that cause paralytic shellfish poisoning. Their appearance in natural waters and their ingestion by aquatic species have a huge socio-economic impact, whereby their monitoring is of the ...

Branching Quantification v. Two-way Quantification [PDF]

Journal of Semantics, 2009
We discuss the thesis formulated by Hintikka (1973) that certain natural language sentences require non-linear quantification to express their meaning. We investigate sentences with combinations of quantifiers similar to Hintikka's examples and propose a novel alternative reading expressible by linear formulae.
