We present some data on the cohomology of the motivic Steenrod algebra over an algebraically closed field of characteristic 0. Our results are based on computer calculations and a motivic version of the May spectral sequence. We discuss features of the associated Adams spectral sequence, and use these tools to give new proofs of some results in classical algebraic topology. We also consider a m...

My aim with these notes is to quickly get the student started with the Adams spectral sequence. To see its power requires that some concrete calculations be done. However, the algebra required can quickly become overwhelming if one starts with the generalized Adams spectral sequence. The classical Adams spectral sequence, in contrast, can be quickly set up and used to do some calculations which...

The so-called ̳Adams‘ Thesis‘ is often understood as the claim that the assertibility of an indicative conditional equals the corresponding conditional probability—schematically: (AT) As(A  B) = P(B | A), provided P(A) ≠ 0. The Thesis is taken by many to be a touchstone of any theorizing about indicative conditionals. Yet it is unclear exactly what the Thesis is. I suggest some precise stateme...

Case Report A 22-years-old woman was admitted to hospital on April 9, 1959 in the 18th week of her first pregnancy. She had been fit until six days before, when she developed lightheadedness, followed by flushing, and a throbbing occipital headache. At 7 p.m. on the day of admission, in bed, she began to have frequent sensations of lightheadedness, accompanied by throbbing occipital headache, a...

OBJECTIVES This study examines the similarity of cognitive assessments using 1 interview in a large population study, the Health and Retirement Study (HRS), and a subsample in which a detailed neuropsychiatric assessment has been performed (Aging, Demographics, and Memory Study [ADAMS]). METHODS Respondents are diagnosed in ADAMS as demented, cognitively impaired without dementia (CIND), or a...

Using operad methods and functional homology operations, we obtain inductive formulae for the differentials of the Adams spectral sequence of stable homotopy groups of spheres. The Adams spectral sequence was invented by Adams [1] almost fifty years ago for the calculation of stable homotopy groups of topological spaces (in particular, those of spheres). The calculation of the differentials of ...

THE skins of many vertebrates react to variations in the amount of hormones of the endocrine glands, especially of the thyroid and pituitary. Moulting in Triturus viridescens is inhibited after both thyroidectomy and hypophysectomy or both operations simultaneously performed. The cornified layers continue to form and the accumulation of these makes the animal appear grimy (Adams and Richards, 1...
