And while the specter of a massacre was dispelled quickly, confusion over what had happened -- and who was who -- persisted briefly as the police clapped handcuffs on four victims and questioned them closely, witnesses said.
Motion-defined form can seem to persist briefly after motion ceases, before seeming to gradually disappear into the background.
Metastability imposes semi-transient signals in the brain, which persist briefly and differ from the usual equilibrium state [13].
Thus, our displays produce a subjective impression that motion-defined forms seem to persist briefly after motion offset before fading into the background of noise, consistent with previous literature [3], [4], [5].
The identification of intermediates that persist only briefly or that are present in only small amounts depends on the availability of powerful, sensitive, and rapid experimental techniques.
First, American officials said Umm Qasr had fallen, while resistance clearly persisted; then, a marine briefly raised an American flag over the city, long enough for it to be filmed and shown repeatedly on Iraqi television.
But we cannot explain why type A persisted for as long or briefly as it did, why it fell from favor to be replaced by type B, or perhaps why it persisted in parts of its historical range while B arose in others or whether type A exhibited stasis and was replaced by unrelated type B or changed, evolved, morphed (depending upon your verb of choice) into type B (or into related types B1 and B2).
Our findings show that in human primary erythroblasts, EPO-induced activation of JNK only occurs briefly, whereas activation of P38 persists.
Banging pans, blowing whistles and demanding that President Hugo Chávez leave office, hundreds of thousands of protesters marched through this capital today as tensions persisted six months after Mr. Chávez was briefly overthrown in the aftermath of a similar protest.
Since a number of these confusions persist in discussions of Everett, we will briefly consider DeWitt and Graham's interpretation and compare it against Everett's description of the relative-state formulation of pure wave mechanics.
