Block combinatorics [PDF]

open access: yesTransactions of the American Mathematical Society, 2006
In this paper we extend the block combinatorics partition theorems of Hindman and Milliken in the setting of the recursive system of the block Schreier families (B^xi) consisting of families defined for every countable ordinal xi. Results contain (a) a block partition Ramsey theorem for every countable ordinal xi (Hindman's theorem corresponding to xi ...

Lateral orbitofrontal neurons acquire responses to upshifted, downshifted, or blocked cues during unblocking

open access: yeseLife, 2015
The lateral orbitofrontal cortex (lOFC) has been described as signaling either outcome expectancies or value. Previously, we used unblocking to show that lOFC neurons respond to a predictive cue signaling a ‘valueless’ change in outcome features ...

Orbitofrontal neurons acquire responses to ‘valueless’ Pavlovian cues during unblocking

open access: yeseLife, 2014
The orbitofrontal cortex (OFC) has been described as signaling outcome expectancies or value. Evidence for the latter comes from the studies showing that neural signals in the OFC correlate with value across features. Yet features can co-vary with value,

Experimental investigation of blocking and discharge regulation function of window-frame dam in viscous debris flow control

open access: yesGeomatics, Natural Hazards & Risk, 2020
The blocking of a window-frame dam and the discharge regulation are both important basic control features for characterizing the regulatory effect of a window-frame dam on debris flow.

Bier??s Block Revisited [PDF]

open access: yesSurvey of Anesthesiology, 1990
Bier introduced his intravenous technique of local anaesthesia to facilitate palliative surgery on the elbow or knee. He cannulated a suitably large vein in the vicinity of the joint to inject procaine after first isolating the operating site with a proximal and a distal tourniquet.

Equidistant Landmarks Fail to Produce the Blocking Effect in Spatial Learning Using a Virtual Water Maze Task with Healthy Adults: A Role for Cognitive Mapping?

open access: yesBrain Sciences
Background/Objectives: Cue competition is a feature of associative learning, whereby during learning, cues compete with each other, based on their relative salience, to influence subsequent performance.
