Why does convection dried cucumbers go up in calories? (hexbear.net)

I found a study that says that dried cucumbers go up in calories because of this or that getting concentrated, but like, the raw cucumber even if eaten whole with all that stuff in there, it still has a minuscule amount of calories. How does drying it raise the calories? Please explain like I'm 5.

The study: https://www.researchgate.net/publication/292994599_Nutritive_value_of_convection-dried_Cucumis_sativus

Edit: I tried rereading it but I still don't get it. If you have a bucket of water with 10 stones in it, and then freeze or steam it, we're still looking at 10 stones. I don't get how this works.

They don't increase in calories, they just have higher energy density. 15 convection dried vegetables will have the same (or less) amount of calories as if they weren't

If you freeze 10 stones, they will increase in volume (because water ice expands when it gets colder) and have a lower density. If you then remove all the water from those stones, they will decrease in volume and increase in density, so you can fit more stone in the same area
