Coherence, not conditional meaning, accounts for the relevance effect

Missing-link conditionals like “If bats have wings, Paris is in France” are generally felt to be unacceptable even though both clauses are true. According to the Hypothetical Inferential Theory, this is explained by a conventional requirement of an inferential connection between conditional clauses. Bayesian theorists have denied the need for such a requirement, appealing instead to a requirement of discourse coherence that extends to all ways of connecting clauses. Our experiment compared conditionals (“If A, C”), conjunctions (“A and C”), and bare juxtapositions (“A. C.”). With one systematic exception that is predicted by prior work in coherence theory, the presence or absence of an inferential link affected conditionals and other statement types in the same way. This is as expected according to the Bayesian approach together with a general theory of discourse coherence

Three dimensional resistance mapping of self-organized Sr3V2O8 nanorods on metallic perovskite SrVO3 matrix

International audienceSelf-organized epitaxial nanorods, obtained by an adapted annealing process after deposition of metallic strontium vanadate perovskite (SrVO3) thin films, are analyzed to determine their structural, chemical and electrical properties. After the identification of the Sr3V2O8 phase of the nanorods by electron diffraction; Electron Energy Loss Spectroscopy investigations show the vanadium oxidation state (V5+ ) for the nanorods. Two scanning probe techniques are deployed to determine the specific local electrical properties of these Sr3V2O8 nanorods. In ambient conditions, local electrical properties are studied by Scanning Spreading Resistance Microscopy based on an Atomic Force Microscope and multiple probe scanning tunneling microscopy is used for the study in ultrahigh vacuum. Both techniques reveal that local electrical resistances of the nanorods are five order of magnitude higher than the resistance of the perovskite SrVO3 matrix. Futhermore, the nanorods are found to be etched by repeating scanning of the conducive Atomic Force Microcopy probe, enabling a three-dimensional depth profile of the nanorods resistance with 3D-Spreading Resistance Microscopy mode. A partial embedding of the nanorods in the underlying SrVO3 film is proved and the impact of the water meniscus at the origin of the selective etching observed during Scanning Spreading Resistance Microscopy, in ambient conditions, is discussed

Adipose tissue is a source of regenerative cells that augment the repair of skeletal muscle after injury

The dynamics of fibroadipogenic progenitors (FAPs) after muscle injury are crucial to ensure efficient regeneration. Here the authors show that a pool of FAPs originates from adipose tissue and are necessary for effective muscle regeneration
