This off-magnet confirmation allowed us to conduct an independent, rigorous test for efficacy of our backward-masking procedure, without impacting the critical design feature of the imaging experiment – to determine the brain response to an uninterrupted flow of stimuli during natural, passive viewing, without the interruptions and potential confound of task demands/performance concerns.
Construction benefited from the flow of federal stimulus funds, he added.
State governments began cutting workers around the same time, and the flow of federal stimulus money began to slow.
The data, released by the Chinese customs agency, capped a series of feeble statistics for August and fanned expectations that the government would speed up the flow and range of stimulus measures.
Here, the use of information theory [3] has helped to formalize such ideas by predicting efficient models for two important coding problems: how to shape (i) the static nonlinear input/output relations, i.e. contrast or characteristic gain, of visual neurons [4] and (ii) their dynamic filtering properties [5] [11] in order to maximize the information flow of naturalistic light stimuli.
In this study, time-dependent BOLD activity changes in the region of interest implicated a sequence of cortical gray matter blood flow changes beginning with hyperemia, followed by hypoperfusion with attenuated response to visual activation and subsequent return of resting blood flow to baseline with recovery of stimulus driven activation [ 89].
In addition to brachial diameter at 60 s after cuff release, flow after cuff deflation within the first 15 s was used as an indicator of stimulus strength, hyperemic flow being the stimulus for endothelial reactivity.
"The vast sum of stimulus money flowing into health information technology created a 'race to adopt' mentality — buy the systems today to get government handouts, but figure out how to make them work tomorrow," Dr. Brailer said.
This collapse caused the deficit to soar: By the first quarter of 2009 — with only a trickle of stimulus funds flowing — federal borrowing had already reached almost 9 percent of G.D.P. To some of us, this says that the economic crisis that began under Mr. Bush is responsible for the great bulk of our current deficit.
