Both privacy and trust are essential elements of an effective e-learning environment. Privacy provides a personal space to a member of an e-learning community, while trust is a crucial enabler for meaningful and mutually beneficial interactions that build and sustain collaboration (e.g. collaborative learning). Identity management (in the form of various degree of anonymity) is one technology-b...

The identity of persons in audiovisual documents represents very important semantic information for content-based indexing and retrieval. The task of speaker’s identity detection can be carried out by exploiting data elements resulting from different modalities (text, image and audio). In this article, we propose an approach for speaker identity indexing in broadcast news using audio content. A...

While identity disturbance has long been considered one of the defining features of Borderline Personality Disorder (BPD), the present study marks only the third empirical investigation to assess it and the first to do so from the perspective of research on narrative identity. Drawing on the rich tradition of studying narrative identity, the present study examined identity disturbance in a grou...

The methods for establishing synthetic lifeforms with rewritten genetic codes comprising non-canonical amino acids (NCAA) in addition to canonical amino acids (CAA) include proteome-wide replacement of CAA, insertion through suppression of nonsense codon, and insertion via the pyrrolysine and selenocysteine pathways. Proteome-wide reassignments of nonsense codons and sense codons are also under...

High specificity in aminoacylation of transfer RNAs (tRNAs) with the help of their cognate aminoacyl-tRNA synthetases (aaRSs) is a guarantee for accurate genetic translation. Structural and mechanistic peculiarities between the different tRNA/aaRS couples, suggest that aminoacylation systems are unrelated. However, occurrence of tRNA mischarging by non-cognate aaRSs reflects the relationship be...

Investigation of the plasmid pHH4 in single colonies of Halobacterium halobium PHH4 indicated transposition of insertion elements in 20% of the colonies. Seven ISH27 insertions were observed as well as one ISH23 insertion. The various copies of ISH27 were compared to the two ISH27 elements already present in pHH4, and to the ISH27 element that was identified in the bacteriopsin (bop) gene of a ...

The presented paper presents the statistical analysis of the dwt coefficients of ear’s images in order to ascertaining the bio-metrics identity of a person. The dwt coefficients matrix contains the frequency variations of ear’s images in three parts; the lower half of the matrix that contains the low frequency elements that make up the flashy part of the ear, the upper half that contain the hig...
