We present foundations for triadic concept analysis of data with graded attributes. Triadic concept analysis departs from the dyadic case by taking into account modi, such as time instances or conditions, under which objects have attributes. That is, instead of a two-dimensional table filled with 0s and 1s (equivalently, binary relation or two-dimensional binary matrix), the input data in triad...

This paper provides an exhaustive account of the semantic features and the logical structure of causative active accomplishment verbs of movement. Following the approach of Componential Analysis, and described within the theoretical framework of Role and Reference Grammar, these verbs are arranged into three subgroups according to a number of semantic variables related to their argument structu...

Cdx2 is an intestine-specific transcription factor known to regulate proliferation and differentiation. We have reported previously that Cdx2 limits the proliferation of human colon cancer cells by inhibiting the transcriptional activity of the beta-catenin-T-cell factor (TCF) bipartite complex. Herein we further elucidate this mechanism. Studies with a classic Cdx2 target gene and a canonical ...

Both TCF-4 and MMP-15 are closely linked to the development of lung cancer, while the regulatory role of TCF-4 in MMP-15 expression is still obscure. Here we found that expression of TCF-4 and MMP-15 was increased in lung cancer cells or tissues versus the normal ones. With gain-or loss-of -function studies, we demonstrated that TCF-4 positively regulated MMP-15 expression in mRNA and protein l...

The TCF-1 gene encodes a putative transcription factor with affinity for a sequence motif occurring in a number of T-cell enhancers. TCF-1 mRNA was originally found to be expressed in a T cell-specific fashion within a set of human and mouse cell lines. In contrast, expression reportedly occurs in multiple nonlymphoid tissues during murine embryogenesis. We have now raised a monoclonal antibody...

The connections between emotion and rationality are reexamined. Historically, Plato’s doctrine of the tripartite soul has established the preconception of a strict separation of emotion/passion from cognition/rationality, encouraging the biased perception that emotions are inherently irrational. To examine whether emotions can be rational, one must first examine the various meanings of rational...

Two experiments used a mutual imitation paradigm to assess 9-, 14-, and 18-month-old infants’ developing understanding of intentions in others. In the first study, 1 experimenter imitated the infants’ actions, and another experimenter performed contingent but different actions on an identical toy. From 9 months of age, infants show discrimination between the mimicking and the contingent experim...

For a set Ω an unordered relation on Ω is a family R of subsets of Ω . If R is such a relation we let G(R) be the group of all permutations on Ω that preserve R, that is g belongs to G(R) if and only if x ∈R implies x ∈R. We are interested in permutation groups which can be represented as G= G(R) for a suitable unordered relation R on Ω . When this is the case, we say that G is defined by the r...

Tcf transcription factors interact with beta-catenin and Armadillo to mediate Wnt/Wingless signaling. We now report the characterization of genes encoding two murine members of the Tcf family, mTcf-3 and mTcf-4. mTcf-3 mRNA is ubiquitously present in embryonic day 6.5 (E6.5) mouse embryos but gradually disappears over the next 3 to 4 days. mTcf-4 expression occurs first at E10.5 and is restrict...

The effect of intra-aortic counterpulsation (IACP) with a balloon upon myocardial oxygen consumption (MVo2), coronaiy blood flow (TCF), and left ventricular performance was studied in 23 anesthetized canine right heart bypass preparations at constant heart rate and cardiac output. In nonhypotensive, nonTCF-limited preparations, IACP produced a fall in left ventricular peak systolic pressure (LV...
