<p>I think you made it up well, and it does apply. I was surprised
the first time I discovered that the dendro of neural "branching"
derived from tree-structures.<br>
</p>
<p>I'm still puzzling over whether Glen has a deeper or more subtle
structure than the "mere"interpenetrating branching structures
implied say by capillaries, where the in/out flow is exchanged. I
am sensing that there is something "special" about the interface
between hierarchical flows and diffusion systems? The
veins/arteries deliver/remove blood but there is another type of
exchange that goes on in between which is more than diffusion
which sort of implies homogenous structure?</p>

Glen's question. Dendrometry in the abstract would be the study

it up, maybe next time.<br>

<p>Interesting to introduce Dendrometry (tree growth) as
_yet another_ metaphorical target domain beyond the liquid
flow, erosion/sedimentation of rivers.</p>
<p>Is there something in tree (plants in general?) growth
that is specifically apt for this purpose? Or were you
perhaps using Dendrometr(i)y in a more creative sense?
Referencing neural growth/function/topology?
Dendodendritic and Axodendritic synapses might be
relevant?<br>
</p>
Trees represent a more "intentional" transport system it
would seem than riverine systems, though if one includes the
organic aspects such as the bosque/etc. maybe not.<br>
<br>
It doesn't seem (too?) unreasonable to imagine that the
Liver (a broad-purpose chemical synthesis factory?) has some
useful/interesting/relevant analogs in trees/plants? While
a tree is nominally 3 dimensional, it is also nearly
1-dimensional in the sense that the cross-section of the
trunk(s), branches, twigs, twiglets, etc are very similar
and within them, they are radially symmetric. <br>
<br>
I am wondering if "braided" branch/root systems like Banyan
Vines might offer some insight?<br>
<p>This is all probably too far afield for Glen's original
question but I can't help but wander a bit on this one?</p>

<div>Subject: [FRIAM] looking for a
word </div>
<div><br>
</div>

I need a word (or short phrase) to refer
to the portion of a network where the
edges converge or diverge (more than
other parts of the network. Examples
might be a river delta or the branching
(debranching?) of blood vessels or
lungs. "Plexus" or "knot" don't work
because they could ambiguously refer to
something like a tapestry or ... well, a
knot, where each thread remains
separate, but winds around other
threads. Something close to
"canalization" seems appropriate. But I
don't want to imply the generation (or
dissolution) of the thing. E.g.
[arter|ang]iogenesis are not the type of
words I'm looking for.<br>
<br>
There's got to be a good word for such,
perhaps from graph theory or "network
theory". Any help will be rewarded by
an IOU for a pint of beer. 8^)<br>
