In the new movie, the pair are challenged by the discovery of an antidote to mutancy that will turn all X-men and women into dull, conformist citizens.
The pair were challenged by Spain's Javier Gomez on the run before kicking for home, with Jonny Brownlee outsprinting Olympic champion Alistair.
In 1999, she represented a pair of individuals whose published election-related literature was challenged.
Just weeks into his new job, Gordon was challenged by two former colleagues in a pair of prominent op-eds.
Despite the screening of conserved gene coding regions, the sequence diversity between species was high and the identification of useful SSR loci applicable to anything other than the most closely related pairs of Phytophthora species was challenging.
It was challenging to pair the smooth and roughened areas of the joints, but the trend was that the friction factor was higher over the roughened areas.
Given the high degree of sequence identity between homeologous pairs (Additional file 3), it was challenging to design optimal qRT-PCR primers that were specific for each gene.
A study done by evolutionary anthropologists demonstrated that spotted hyenas outperform chimpanzees on cooperative problem-solving tests; captive pairs of spotted hyenas were challenged to tug two ropes in unison to earn a food reward, successfully cooperating and learning the maneuvers quickly without prior training.
Also, the tradition of giving transfusions in pairs (2, 4, 6) has been challenged, with similar outcomes from single-transfusion units when needed (Naylor et al. 2010 (2++)).
Previous studies have shown that when hippocampal synapses are challenged by pairs of APs separated by only a few milliseconds, the second response is generally profoundly depressed with respect to the first (Stevens and Wang, 1995; Dobrunz et al., 1997; Brody and Yue, 2000).
