This paper tests the influence of the training dataset dimension on a recently proposed orthographic learning system, inspired from biological sequence analysis and successfully applied to cognate identification. This system automatically aligns a given set of cognate pairs producing a meaningful training dataset, learns from it substitution parameters using a PAM-like technique and utilises th...
The fidelity of translation selection begins with the base pairing of codon-anticodon complex between the m-RNA and tRNAs. Binding of cognate and near-cognate tRNAs induces 30S subunit of the ribosome to wrap around the ternary complex, EF-Tu(GTP)aa-tRNA. We have proposed that large thermal fluctuations play a crucial role in the selection process. To test this conjecture, we have developed a t...
Previously, we identified that both fingers 1 and 2 in the three Cys2His2 zinc-finger domains (TZD) of testis zinc-finger protein specifically bind to its cognate DNA; however, finger 3 is non-sequence-specific. To gain insights into the interaction mechanism, here we further investigated the DNA-binding characteristics of TZD bound to non-specific DNAs and its finger segments bound to cognate ...
The present study establishes an electrophysiological index of lexical access in speech production by exploring the locus of the frequency and cognate effects during overt naming. We conducted 2 event-related potential (ERP) studies with 16 Spanish-Catalan bilinguals performing a picture naming task in Spanish (L1) and 16 Catalan-Spanish bilinguals performing a picture naming task in Spanish (L...
We have used a stepwise increase in ligand complexity approach to estimate the relative contributions of the nucleotide units of DNA containing 7,8-dihydro-8-oxoguanine (oxoG) to its total affinity for human 8-oxoguanine DNA glycosylase (OGG1) and construct thermodynamic models of the enzyme interaction with cognate and non-cognate DNA. Non-specific OGG1 interactions with 10-13 nt pairs within ...
BACKGROUND The gene bldA for leucyl [Formula: see text] is known for almost 30 years as a key regulator of morphogenesis and secondary metabolism in genus Streptomyces. Codon UUA is the rarest one in Streptomyces genomes and is present exclusively in genes with auxiliary functions. Delayed accumulation of translation-competent [Formula: see text] is believed to confine the expression of UUA-con...
In this paper, we introduce a threshold free approach, motivated from Chinese Restaurant Process, for the purpose of cognate clustering. We show that our approach yields similar results to a linguistically motivated cognate clustering system known as LexStat. Our Chinese Restaurant Process system is fast and does not require any threshold and can be applied to any language family of the world.
We report results of experiments aimed at improving the translation quality by incorporating the cognate information into translation models. The results confirm that the cognate identification approach can improve the quality of word alignment in bitexts without the need for extra resources.
In this paper, we explore the use of convolutional networks (ConvNets) for the purpose of cognate identification. We compare our architecture with binary classifiers based on string similarity measures on different language families. Our experiments show that convolutional networks achieve competitive results across concepts and across language families at the task of cognate identification.
