We look at extensions (i.e., stronger logics in the same language) of the Belnap-Dunn four-valued logic. We prove the existence of a countable chain of logics that extend the Belnap-Dunn and do not coincide with any of the known extensions (Kleene’s logics, Priest’s logic of paradox). We characterize the reduced algebraic models of these new logics and prove a completeness result for the first ...

The objective of this new Brazilian consensus is to update and to continue the standardization of the principal terms and fundamental patterns in chest CT scans in Portuguese. There is a succinct definition of the principal terms used to describe chest CT findings, as well as illustrations of classic examples. The group of authors comprised radiologists specializing in chest radiology and holdi...

We generalize a theorem of Mazur concerning the universal norms of an abelian variety over a Zp-extension of a complete local field. Then we apply it to the proof of a control theorem for abelian varieties over global function fields.

ship of twenty-four defective or retarded pupils, comprising ten from the first grade, ten from the second, two from the third, and two from the fifth. The number varied from time to time through dismissals and recruits, until altogether forty-nine pupils have received special treatment adapted to their individual needs. I desire to invite your attention to several particularly interesting and ...

The robust stability problem of continuous-time singular systems with multiple state delays and bounded parametric uncertainties is considered. Both commensurate and non-commensurate delays are investigated. On the basis of the linear fractional transformations (LFTs) framework and -analysis, a systematic approach is derived to convert the robustness problem to a robust nonsingularity problem. ...

Participant sex and a theorized correlate of biological sex, relational interdependence, were tested as relative predictors of the extent to which daters 1) missed and 2) used emotional support to cope when geographically separated from their dating partners. One hundred twenty-four daters completed multiple measures of missing and coping during their colleges' winter breaks. Results from regre...

This study investigates the use of relative clauses in French children's narrative monologues. Narrative texts were collected from French-speaking monolinguals in four age groups (five, seven, ten years and adults). Twenty subjects from each group were asked to tell a story based on a picture book consisting of twenty-four images without text (Frog, Where are you?). Relative constructions were ...

W H E N the Manhigh capsule system was being designed in the fall of 1955, the pr imary objective was a maximum performance system of minimum weight that could lift a man into a space equivalent environment for twenty-four hours. This objective 'had to be met safely and supply an answer to what the man could :do if any specific componem failed. Beyond this, an effort was made to provide him wit...

The Gibbard-Satterthwaite theorem is a cornerstone of social choice theory, stating that an onto social choice function cannot be both strategy-proof and non-dictatorial if the number of alternatives is at least three. The Duggan-Schwartz theorem proves an analogue in the case of set-valued elections: if the function is onto with respect to singletons, and can be manipulated by neither an optim...
