An earley parsing algorithm for range concatenation grammars [PDF]

open access: yes, 2009
We present a CYK and an Earley-style algorithm for parsing Range Concatenation Grammar (RCG), using the deductive parsing framework. The characteristic property of the Earley parser is that we use a technique of range boundary constraint propagation to ...

Ten virtues of structured graphs [PDF]

open access: yes, 2009
This paper extends the invited talk by the first author about the virtues of structured graphs. The motivation behind the talk and this paper relies on our experience on the development of ADR, a formal approach for the design of styleconformant ...

Generation of Two-Dimensional Grammar Based Pattern Languages using Array Rewriting P System

open access: yesInternational Journal of Innovative Technology and Exploring Engineering, 2019
The theory of membrane computing was formulated by Paun as an attempt to formulate a computational model inspired by the way in which the living cells function. P systems which is a highly distributed, parallel, theoretical model and is an area of special interest in recent times.

Accepting grammars and systems [PDF]

open access: yes, 2007
We investigate several kinds of regulated rewriting (programmed, matrix, with regular control, ordered, and variants thereof) and of parallel rewriting mechanisms (Lindenmayer systems, uniformly limited Lindenmayer systems, limited ...

A polynomial-time parsing algorithm for TT-MCTAG [PDF]

open access: yes, 2009
This paper investigates the class of Tree-Tuple MCTAG with Shared Nodes, TT-MCTAG for short, an extension of Tree Adjoining Grammars that has been proposed for natural language processing, in particular for dealing with discontinuities and word order ...

Rewriting P systems: improved hierarchies [PDF]

open access: yes, 2005
Generally, for proving universality results about rewriting P systems one considers matrix grammars in the strong binary normal form. Such grammars contain both matrices with rules used in the appearance checking mode and matrices without appearance ...

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

open access: yesMolecular 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 ...

A study in parallel rewriting systems [PDF]

open access: yes, 1980
In this paper we study systematically three basic classes of grammars incorporating parallel rewriting: Indian parallel grammars, Russian parallel grammars and L systems.

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

open access: yesFEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐
