Inline vertical diagrams

Question

Is there a package that allows for vertical in-line diagrams, like the one below?

I've tried the following code inline using xy-pic
documentclass{article}
usepackage[all,cmtip,2cell]{xy}
begin{document}
This is an example. This is an example. This is an example. This is an example. This is an example. This is an example. $xymatrixrowsep{.1mm}xymatrix{mathcal{E} ar[dd]     F  mathcal{B}}$ This is an example. This is an example. This is an example. This is an example. This is an example. This is an example. 
end{document}

with the following result

but I was hoping for a method that didn't disturb the line-height placement of the next line down, like in the example above.

You can simply use raisebox{<up/down shift>}{content to shift}
For example
 bla bla bla raisebox{0pt}{$begin{matrix}mathcal{E}downarrowmathcal{B}end{matrix}$} bla bla

will produce

Here how raisebox{} works:
 in the middle of the text....
 raisebox{0pt}{
 $begin{matrix}
 mathcal{E}downarrowmathcal{B}end{matrix}$
 }
 at the top of the text...
 raisebox{10pt}{
 $begin{matrix}mathcal{E}downarrowmathcal{B}end{matrix}$
 }
 at the bottom of the text....
 raisebox{-10pt}{
 $begin{matrix}mathcal{E}downarrowmathcal{B}end{matrix}$
 }

Upgrade for labeled arrows
Using a two column matrix is it easy (maybe not so pretty) to label the vertical line. Eg
 $
 setlength{arraycolsep}{0pt}
 begin{matrix}
 mathcal{E}&
 downarrow&F 
 mathcal{B}&
 end{matrix}$

I propose this variant approach, using only the stackengine package and basic latex commands:
documentclass{article}
usepackage[usestackEOL]{stackengine}

begin{document}

This is an example. This is an example. This is an example. This is an example. This is an example. This is an example.setstackgap{L}{2.2ex}$Vectorstack{mathcal{E} phantom{scriptstyle F!}downarrow {!scriptstyle F}  mathcal{B}}$ This is an example. This is an example. This is an example. This is an example. This is an example. This is an example.

end{document}

Here there are two approaches:

The first is to use the common commands of amsmath and amssymb.

$overset{mathbb{E}}{underset{mathbb{B}}{scriptstyle downarrow}} scriptscriptstyle F$

To use xy package which contains (xy-pic).

You here can see the different approaches in the screenshot.
documentclass[a4paper,12pt]{article}
usepackage{amsmath,amssymb}
usepackage[all,cmtip]{xy}
usepackage{parskip}
begin{document}
Et sem luctus quisque porta viverra hymenaeos consequat et ridiculus commodo platea mollis sem erat quam sollicitudin, luctus arcu lacus vestibulum nam Pharetra purus ullamcorper nam cursus sollicitudin nec risus $xymatrix@C=.2pt{
mathcal{E} ar[d]^F& 
mathcal{B} &
}hspace{-.25cm}$ lipsum $overset{mathcal{E}}{underset{mathcal{B}}{scriptstyle downarrow}}$. Sit volutpat etiam. Dapibus. Dictumst quisque. Suspendisse pulvinar dignissim. Natoque volutpat dui sodales viverra volutpat lacus $overset{mathbb{E}}{underset{mathbb{B}}{scriptstyle downarrow}} scriptscriptstyle F$. Fusce pede proin rutrum enim. Velit, diam taciti. Praesent hymenaeos consequat, libero cum accumsan.
end{document}
