Equivalent Transformations and Regularization in Context-Free Grammars
Cybernetics and Information Technologies, 2015 Regularization of translational context-free grammar via equivalent transformations is a mandatory step in developing a reliable processor of a formal language defined by this grammar.

Chomsky-Schützenberger parsing for weighted multiple context-free languages
Journal of Language Modelling, 2017 We prove a Chomsky-Schützenberger representation theorem for multiple context-free languages weighted over complete commutative strong bimonoids. Using this representation we devise a parsing algorithm for a restricted form of those devices.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

On multiple context-free grammars
Theoretical Computer Science, 1991 This paper discusses some generalizations of context free grammars. The resulting languages lie between the class of context free languages and the class of context sensitive languages. The paper investigates and establishes containment relations, many of them strict, between the newly introduced classes of languages.

Lexicalized context-free grammars [PDF]
Proceedings of the 31st annual meeting on Association for Computational Linguistics -, 1993 Lexicalized context-free grammar(LCFG) is an attractive compromise between the parsing efficiency of context-free grammar (CFG) and the elegance and lexical sensitivity of lexicalized tree adjoining grammar (LTAG). LCFG is a restricted form of LTAG that can only generate context-free languages and can be parsed in cubic time.

Molecular Oncology, EarlyView.LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

On the Comparison of Context-Free Grammars
CoRR, 2017 In this paper we consider the problem of context-free grammars comparison from the analysis point of view. We show that the problem can be reduced to numerical solution of systems of nonlinear matrix equations. The approach presented here forms a basis for probabilistic comparison algorithms oriented to automatic assessment of of student's answers in ...

Spatial biology in cancer epigenetics
Molecular Oncology, EarlyView.Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Effective ambiguity checking in biosequence analysis
BMC Bioinformatics, 2005 Background Ambiguity is a problem in biosequence analysis that arises in various analysis tasks solved via dynamic programming, and in particular, in the modeling of families of RNA secondary structures with stochastic context free grammars.
