Specialized fiber electrograms were recorded in 64 patients during open-heart surgery. Intervals were measured from the proximal His bundle, distal His bundle, and right and left bundle branches to the earliest QRS deflection in the limb lead ECG (pH-Q, dH-Q, RB-Q, and LB-Q interval, respectively). There was an increase of pH-Q intervals with increasing age such that at age 3 months the normal ...

Objective: Quality assurance of large ontological systems such as SNOMED CT is an indispensable part of the terminology management lifecycle. We introduce a hybrid structural-lexical method for scalable and systematic discovery of novel anomalies in SNOMED CT. The structural component is based on shared isa relations to other concepts. The lexical component leverages shared words in description...

Results from chronometric and speech errors studies provide convergent evidence for both lower and upper bounds on interaction within the speech production system. Some degree of cascading activation is required to account for patterns of speech errors in neurologically intact and impaired speakers as well as the results of recent chronometric studies. However, the strength of this form of inte...

over, and what kinds of symbol systems should we create for them? Everytime a new phenomenon is identified as a bottleneck or as problematic, the very actsof describing the phenomenon, defining it,and creating a set of symbols to represent its abstractions are symbolic (in both senses of the word!). The benefits: decreasedlearning time and more powerful rules,hence improved ...

The role that lexical storage and computation play in the processing ofmorphologically complex words is highly debated. Thus far, studies that contrastthese processes have yielded widely varying results. At present, three viewpointspredominate: (1) the full storage model, in which all known words are storedseparately in the mental lexicon, (2) the full parsing model, in which al...

The present study sought to investigate the effect of explicit instruction of lexical bundles (LBs) on the development of Iranian English for Academic Purposes (EAP) students’ writing quality and also their receptive and productive knowledge of Lexical Bundles (LB). Assigned to two experimental and control groups, the eighty participants took pre- and post-tests of writing tasks and the recepti...

Event Structures (ESs) address the representation of direct relationshipsbetween individual events, usually capturing the notions of causality and conflict. Up tonow, such relationships have been static, i.e. they cannot change during a system run.Thus, the common ESs only model a static view on systems. We make causality dynamicby allowing causal dependencies between some event...

Lexical networks can be used with benefit for semantic analysis of texts, word sensedisambiguation (WSD) and in general for graph-based Natural Language Processing.Usually strong relations between terms (e.g.: cat --> animal) are sufficient to help for thetask, but quite often, weak relations (e.g.: cat --> ball of wool) are necessary. Ourpurpose here is to acquire such relation...

The semantic web is defined by a set of methods and technologies enabling softwareagents to reason about the contents of Web resources. This vision of the Web depends onthe construction of ontologies and the use of metadata to represent these resources. Theobjective of our thesis is to annotate semantically tagged documents related to a domainof interest. These documents may...
