On the Relation between Context-Free Grammars and Parsing Expression Grammars [PDF]
, 2014 Context-Free Grammars (CFGs) and Parsing Expression Grammars (PEGs) have several similarities and a few differences in both their syntax and semantics, but they are usually presented through formalisms that hinder a proper comparison.

A General, Sound and Efficient Natural Language Parsing Algorithm based on Syntactic Constraints Propagation [PDF]
, 1997 This paper presents a new context-free parsing algorithm based on a bidirectional strictly horizontal strategy which incorporates strong top–down predictions (deriva- tions and adjacencies).

Graph Parsing as Graph Transformation [PDF]
, 2020 Hyperedge replacement (HR) allows to define context-free graph languages, but parsing is NP-hard in the general case. Predictive top-down (PTD) is an efficient, backtrack-free parsing algorithm for subclasses of HR and contextual HR grammars, which has been described and implemented in earlier work, based on a representation of graphs and grammar ...

Advanced Materials Technologies, EarlyView.A porous crystalline sensing layer has been developed in conjunction with a nanomechanical sensor for the sensitive detection of volatile fatty acids (VFAs) in admixture at high relative humidity. The sensitive, selective sensor based on supramolecular design improves the economic viability of anaerobic digesters toward a carbon neutral society ...

Advanced Theory and Simulations, EarlyView.Inspired by natural light‐harvesting systems, this study computationally investigates a synthetic antenna by arranging cationic free‐base porphyrin molecules on an anionic clay surface. Using a multiscale quantum mechanics/molecular mechanics (QM/MM) approach combined with a multifidelity machine learning method, excitation energies are predicted ...

Advanced Error Recovery during Top-Down Parsing [PDF]
, 2015 Syntaktický analyzátor je jednou z nejdůležitějších částí překladače při často používaném přístupu syntaxí řízený překlad. Při tomto přístupu řídí syntaktický analyzátor sémantické akce a generování abstraktního syntaktického stromu.

A Prion‐Like Domain in EBV EBNA1 Promotes Phase Separation and Enables SRRM1 Splicing
Advanced Science, EarlyView.This study discoveries that EBV EBNA1 behaves as a prion‐like protein, verified using cell‐based assays and the Saccharomyces cerevisiae Sup35p prion identification system. The prion‐like domain of EBNA1 drives liquid–liquid phase separation. EBNA1 interacts with the splicing factor SRSF1 to regulate the expression of the SRRM1 splicing isoforms ...

A Minimal Span-Based Neural Constituency Parser
, 2017 In this work, we present a minimal neural model for constituency parsing based on independent scoring of labels and spans. We show that this model is not only compatible with classical dynamic programming techniques, but also admits a novel greedy top ...

Advanced Science, EarlyView.In this study, C‐TAH, as multifunctional nanosheets, is developed with tannic acid and histone aptamer coverage. C‐TAH displays mild cytotoxicity, robust dsDNA and NETs/EETs binding efficiency, and potent antioxidant and antibacterial ability in vitro. C‐TAH treatment ameliorates dysregulated inflammation and restores hearing function in animal models,
