Machines for attribute grammars
Two automata models are introduced that play, with respect to attribute grammars and attribute-evaluation for them, the same role as pushdown automata have with respect to context-free grammars and their parsing. It is shown, in fact, that these automata define the same class of string-to-value translations as attribute grammars. Their class of tree-to-

Interpretation and reduction of attribute grammars [PDF]
An attribute grammar (AG) is in reduced form if in all its derivation trees every attribute contributes to the translation. We prove that, eventhough AG are generally not in reduced form, they can be reduced, i.e., put into reduced form, without modifying their translations. This is shown first for noncircular AG and then for arbitrary AG.

Abstract Objective Recent research has highlighted the potentially deleterious effects of anti‐obesity public health campaigns on vulnerable audiences such as those at risk of, or diagnosed with, eating disorders (ED). The qualitative experiences of campaigns in this population group have been little explored.

BSML: A Binding Schema Markup Language for Data Interchange in Problem Solving Environments (PSEs)
We describe a binding schema markup language (BSML) for describing data interchange between scientific codes. Such a facility is an important constituent of scientific problem solving environments (PSEs).

Reenactment: An embodied cognition approach to meaning and linguistic content [PDF]
A central finding in experimental research identified with Embodied Cognition (EC) is that understanding actions involves their embodied simulation, i.e. executing some processes involved in performing these actions.

The formal power of one-visit attribute grammars [PDF]
An attribute grammar is one-visit if the attributes can be evaluated by walking through the derivation tree in such a way that each subtree is visited at most once.

Neuropsychiatric symptoms associated multimodal brain networks in Alzheimer's disease
Neuropsychiatric symptoms (NPS)‐associated multimodal pattern spatially involves frontal‐subcortical limbic circuits, which significantly associated with cognitive performance and progression. Different frontal‐subcortical limbic circuit regions suffer different pathogenic mechanisms in Alzheimer's disease subjects concomitant with NPS.

VLGrammar: Grounded Grammar Induction of Vision and Language [PDF]
Cognitive grammar suggests that the acquisition of language grammar is grounded within visual structures. While grammar is an essential representation of natural language, it also exists ubiquitously in vision to represent the hierarchical part-whole structure. In this work, we study grounded grammar induction of vision and language in a joint learning

Grammars over the Lambek Calculus with Permutation: Recognizing Power and Connection to Branching Vector Addition Systems with States [PDF]
In (Van Benthem, 1991) it is proved that all permutation closures of context-free languages can be generated by grammars over the Lambek calculus with the permutation rule (LP-grammars); however, to our best knowledge, it is not established whether the converse holds or not.

AbstractThis paper develops a notion of attributes on tree grammars. We study the case when graphs of attributes are associated with terminal symbols of tree grammars. An algebraic formalism is given in this case for attributed tree grammars. We also describe algorithms for the test of noncircularity.
