Is Dan Uggla/Adam Dunn breaking out of his Slump?

I acquired Dan Uggla for Aaron Hill straight up because friend said he was frustrated with Uggla. Today he hits 2 run blast, going 2/3, yesterday 2/3 and then 1/5. Is Dan Uggla out of his slump? What about Adam Dunn, two homeruns in last three games?
