We consider the effect of the reversibility of the chemical reaction on the propagation and stability of laminar premixed flames, an important realistic aspect which has received little attention in the literature. For the sake of analytical tractability and clarity of the results, the thermodiffusive approximation of constant density is adopted, along with the simple framework of a single reve...

Data continuously stream into our minds, guiding our learning and inference with no trial delimiters to parse our experience. These data can take on a variety of forms, but research on causal learning has emphasized discrete contingency data over continuous sequences of events. We present a formal framework for modeling causal inferences about sequences of point events, based on Bayesian infere...

The evolution of technology and the constant digitalisation strongly influence how consumers behave, how markets develop, and how companies and consumers interact. By offering many channels, companies attempt to react to these developments. In recent years, researchers as well as practitioners have proposed omnichannel management as the best approach to offer several channels. An omnichannel st...

Retrieval effectiveness depends on both the retrieval model and how terms are extracted and indexed. For Chinese, Japanese and Korea text, there are no spaces to delimit words. Indexing using hybrid terms (i.e. words and bigrams) was not very effective in NTCIR-II open evaluation. In this evaluation, we found that using the 2-Poisson model with hybrid term indexing can be effective in retrieval...

Field normalized citation rates are well-established indicators for research performance from the broadest aggregation levels such as countries, down to institutes and research teams. When applied to still more specialized publication sets at the level of individual scientists, also a more accurate delimitation is required of the reference domain that provides the expectations to which a perfor...

Criminals may purposely try to hide their identity by using a voice disguise such as imitating another dialect. This paper empirically investigates the power of dialect as an attribute that listeners use when identifying voices and how a switch of dialect affects voice identification. In order to delimit the magnitude of the perceptual significance of dialect and the possible impact of dialect ...

Several corpora have been annotated with negation scope—the set of words whose meaning is negated by a cue like the word “not”—leading to the development of classifiers that detect negation scope with high accuracy. We show that for nearly all of these corpora, this high accuracy can be attributed to a single fact: they frequently annotate negation scope as a single span of text delimited by pu...

Research on police culture has generally fallen within one of two competing camps—one that depicts culture as an occupational phenomenon that encompasses all police officers and one that focuses on officer differences. The latter conceptualization of police culture suggests subcultures (or at least segmentation) that bound or delimit the occupational culture. Using survey data collected as part...

In [Le2] the following class of billiards was studied: For f : [0,+∞) −→ (0,+∞) convex, sufficiently smooth, and vanishing at infinity, let the billiard table be defined by Q, the planar domain delimited by the positive x-semiaxis, the positive y-semiaxis, and the graph of f . For a large class of f we proved that the billiard map was hyperbolic. Furthermore we gave an example of a family of f ...
