On Intuitionistic Fuzzy Context-Free Languages
Journal of Applied Mathematics, 2013 Taking intuitionistic fuzzy sets as the structures of truth values, we propose the notions of intuitionistic fuzzy context-free grammars (IFCFGs, for short) and pushdown automata with final states (IFPDAs).

Towards a Context-Free Machine Universal Grammar (CF-MUG) in Natural Language Processing
IEEE Access, 2020 In natural language processing, semantic document exchange ensures unambiguity and shares the same meaning for documents sender and receiver cross different natural languages (e.g., English to Chinese), this difference makes the translation between ...

MINIMIZATION OF CONTEXT-FREE GRAMMARS
Prikladnaya Diskretnaya Matematika, 2019 Summary: This paper solves the problem of transforming the initial context-free grammar (CF-grammar) without excess characters into equivalent CF-grammar with less complexity. To solve this problem, the following relation on the set of a CF-grammar non-terminals is introduced: \(E = \{(X,Y): (X=Y) \vee (X\to \alpha\Leftrightarrow Y\to \beta \wedge\vert

Analyzing Ambiguity of Context-Free Grammars [PDF]
BRICS Report Series, 2006 <p>It has been known since 1962 that the ambiguity problem for context-free grammars is undecidable. Ambiguity in context-free grammars is a recurring problem in language design and parser generation, as well as in applications where grammars are used as models of real-world physical structures.

FEBS Open Bio, EarlyView.Lactoferrin promotes wound healing by activating MAPK, PI3K/Akt, and extracellular matrix pathways, enhancing fibroblast remodeling, proliferation, and re‐epithelialization. These mechanisms highlight its therapeutic potential in inflammation control, tissue repair, and remodeling.

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells
FEBS Open Bio, EarlyView.BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.

An Approach to Analyze the Ambiguity in RNA Structure
Sultan Qaboos University Journal for Science, 2010 DNA and RNA are two very important bio-molecules of the human cell. RNA is the second major form of nucleic acid in human cells that plays an intermediary role between DNA and functional protein. Several classes of RNA’s are found in cells, each with a /

Information and Control, 1978 In this paper we develop a theory of context-free graph grammars. Formal properties of such grammars are proven, with particular attention to graph language recognizability.

Safety and Efficacy of GLP‐1 Receptor Agonists in Adults With Epilepsy, Obesity, and Type 2 Diabetes
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Managing obesity in patients with epilepsy is complicated by the weight‐gaining properties of essential antiseizure medications (ASMs) such as valproate and pregabalin. We evaluated the safety and efficacy of initiating glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) in this population.
