Separated finitely supported $Cb$-sets
The monoid $Cb$ of name substitutions and the notion of finitely supported $Cb$-sets introduced by Pitts as a generalization of nominal sets. A simple finitely supported $Cb$-set is a one point extension of a cyclic nominal set. The support map of a simple finitely supported $Cb$-set is an injective map. Also, for every two distinct elements of a simple finitely supported $Cb$-set, there exists...
متن کاملAcute Effects of Ecstasy on Memory Are more Extensive than Chronic Effects
Introduction: Exposure to 3, 4- methylenedioxymethamphetamine (MDMA) could lead to serotonergic system toxicity in the brain. This system is responsible for learning and memory functions. Studies show that MDMA causes memory impairment dose-dependently and acutely. The present study was designed to evaluate the chronic and acute effects of MDMD on spatial memory and acquisition of passive avoid...
متن کاملOn coding uncountable sets by reals
The following is our main result. Theorem 1.1 Suppose that A ⊆ ω1 and = [A]. Then there exists a cardinal preserving generic extension [x] of the ground universe by a generic real x such that (i) A ∈ [x] – this implies [x] = [x], and A ∈ Δ 1 (x) in [x], (ii) x is a minimal real over , that is, x ∈ , and if a set Y belongs to [x], then x ∈ [Y ] or Y ∈ , 1) (iii) there is a club C ∈ [x], C ⊆ ω1, ...
متن کاملMaximal Clones on Uncountable Sets That Include All Permutations
We first determine the maximal clones on a set X of infinite regular cardinality κ which contain all permutations but not all unary functions, extending a result of Heindorf’s for countably infinite X. If κ is countably infinite or weakly compact, this yields a list of all maximal clones containing the permutations since in that case the maximal clones above the unary functions are known. We th...
متن کاملMargaret McCartney: Remember that doctors are more trusted than journalists.
In the past few months the Daily Mail has excoriated GPs for letting “millions” down by being “shut in the afternoon,” for “failing an estimated 32 000 cancer patients,” and for “failing to diagnose patients with early dementia.” It often does this on the front page in large font, and I know that these headlines hurt many GPs who work long and hard under intolerable pressure. Free speech is imp...
