Multisensory effects of mask wearing on speech intelligibility and the benefit of multilingualism.

Purpose: Due to the pandemic of the Covid-19 disease, it became common to wear masks on some public spaces. By covering mouth and nose, visual-related speech cues are greatly reduced, while the auditory signal is both distorted and attenuated. The present study aimed to analyze the multisensory effects of mask wearing on speech intelligibility and the differences in these effects between participants who spoke 1, 2 and 3 languages.

Comparative performance between "next generation" multiplex systems and the new European Standard Set of STR markers in the Portuguese Population.

Various multiplex STR systems have been developed by the major commercial companies in the forensic genetics field to comply with the recent establishment of the global European Standard Set (ESS) of markers. Of the various alternatives available, our laboratory decided to test the recent ESSplex Plus system (Qiagen) and the NGM kit (Life Technologies), which share the same 15 STR loci and comprise the most recently established ESS markers (D1S1656, D2S441, D10S1248, D12S391 and D22S1045). Apart from evaluating the kits' technical performances, a population and segregation study was carried out on a Portuguese sample, with the aim of introducing the ESS markers in routine forensic casework.
