Recently, a segment of the Adams-Shuswap sockeye salmon (Oncorhynchus nerka) population initiated freshwater migration several weeks earlier than historically recorded, resulting in high mortality rates. The comigrating Chilko population maintained their historic river entry timing and did not experience elevated mortality. To test the hypothesis that population-specific differences in physiolo...

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...

White Hall Madison, WI 53706 [email protected] REVIEW OF: The Bounds of Cognition, Frederick Adams and Kenneth Aizawa, 2008, Malden: Blackwell Publishing. Fred Adams and Ken Aizawa have done a fine thing in this short and engaging challenge to the hypothesis of extended cognition. In brief, they have (i) su...

The modelling of many real life phenomena for which either the parameter estimation is diicult, or which are subject to random noisy perturbations, is often carried out by using stochastic ordinary differential equations (SODEs). For this reason, in recent years much attention has been devoted to deriving numerical methods for approximating their solution. In particular, in this paper we consid...

Statistical methods for detecting changes in longitudinal time series of psychophysiological data are limited. ANOVA and mixed models are not designed to detect the existence, timing, or duration of unknown changes in such data. Change point (CP) analysis was developed to detect distinct changes in time series data. Preliminary reports using CP analysis for fMRI data are promising. Here, we ill...
