That article paints a fantastic contrast between "speaking to" in an ungrounded state vs. "speaking to" in a grounded state. When speaking to a collection of idealists, it's relatively trivial to sidetrack them into some region where their evocative triggers are "dog whistles". But when speaking to a collection of skeptics, it's fairly difficult push them into an ungrounded region.
But the problem is invariant: that of "speaking to". Trump beat Clinton, hands down, on the "speaking to" front. "Sophisticated" people, who are used to and comfortable with parsing the details of some complicated plan or infrastructure, tended to go with Clinton, whereas those of us who would prefer our representatives to speak in "poetry", allowing us to fill in the [whatever] details, went with Trump. A fundamental problem these days is "political stalking" and "viral memeing". It's difficult to balance one's presentation to both the nerds and the consumers of poetry. Obama does it fairly well. Clinton did not.

They say Germans have a word for everything because we can chain words together like pearls on a string. In German I would say "Netzwerkverzweigung" (network-branching/bifurcation) or "Netzwerkverdichtung" (network-consolidation/concentration).

Roger - Interesting to introduce Dendrometry (tree growth) as _yet another_ metaphorical target domain beyond the liquid flow, erosion/sedimentation of rivers. 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? 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. I am wondering if "braided" branch/root systems like Banyan Vines might offer some insight? This is all probably too far afield for Glen's original question but I can't help but wander a bit on this one? - Steve

I hadn't thought of trees explicitly, I was working the branching geometries of neural dendrites and crystals. But trees are a fine example as well, and the exemplar of the class of all tree structures. I thought the branchedness of the blood flow into and out of the liver was the whole point of Glen's question. Dendrometry in the abstract would be the study of branching structures to find where the branchedness is essential to the phenomena under study. I thought I was making it up, maybe next time. -- rec -- On Sat, Aug 18, 2018 at 11:28 AM Steven A Smith <[hidden email]> wrote:

Roger - 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. 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? - Steve On 8/18/18 11:15 PM, Roger Critchlow

Thanks, everyone! These are all excellent leads. And, yes, the reason "filtration" is evocative is because the liver filters the blood (as well as the methodological map to indexing structures). And the space-filling nature of rivers and neural and tree growth, I think, impacts such filtration directly. It's "fractal" in the sense of optimizing some thing like surface area. My (not a biologist) guess is that all exchange mechanisms use such a "bed". Lungs branch out for gas exchange. The liver branches out and in. The whole system is the "bed" ... or the "foliage". What I need is a word for a part of the bed. We have a word for things like the "trunk" or the "stem".
But "dendrometry" is similar to "persistent homology" in the sense that it's a generic term for the *property* exhibited by some system. What I'm looking for would be "the *part* of the system with dendrometry = X" or "the part of the system exhibiting the persent homology of X". So, it has to be a noun. The ideas like "type X hub" or "convergent node" or "junction node" are more on-target grammatically. And, I need some directionality to it, too. The input for the liver acinus is divergent, whereas the output is convergent. Ideally, I could refer to either of them and just plop a qualifier like con- or div- on the front. I think it was Roger's "dendrite" idea made me think of "sprout" ... "bushy sprouts" versus "singular sprouts" or somesuch. But what's the inverse of "sprout"? I don't know. I'll be boggled if there isn't *already* a word for this "just branching" or "just de-branching" component of a larger network.

"Plenum" is a fantastic idea. I rejected "manifold" originally because I've tried to use it in conversations with biologists before and it just didn't seem to communicate the idea. It baffles me a bit because the word is so directly available as "many folds". But perhaps it's too engineering-oriented. Plenum may well be what I'm looking for, though. It has similar problems to "plexus", though, in its etymology. Where "plexus" can imply braiding where the threads don't merge/branch, but merely criss-cross, "plenum" can mean "full space", which might well refer to the center of the bed (leaf nodes in the lung or tree case, smallest diameter in the capillary bed case) where the network comes closest to filling the space. Plexus has an advantage over plenum, though, because it's already used in the way I want. E.g. afferent and efferent plexuses.

Glen,
I haven’t followed this thread closely enough to have a good sense of what you are after, so apologies if this is off point. When you first asked, and hadn’t talked yet about specifically tree-like networks, I was thinking that the converging end could borrow the term “coalescent” from population genetics. I don’t think the geneticists have a corresponding word for the final-time data that it is the purpose of the coalescent to assign a history to, but I guess the counterpart would be the “divergent”. That would have been a strange notion for a merely-concentrated part of a network that wasn’t both treelike and directed in some sense, so I stayed quiet. But it seems treelike networks with sources and destinations are still in the conversation. Of course this has the problem that both words are natively adjectives, themselves derived from transitive verbs, which have now been repurposed as nouns in technical fields. But maybe in linguistic typology that isn’t so uncommon (Bill Croft has told me this, but I don’t have a particularly good reference. Perhaps http://www.unm.edu/~wcroft/WACabst.html or his book(s?))

Coalescence is a very nice sidetrack, actually. It, again, takes me back to the notion of *a* filtration, in particular ascending and descending filtrations. A brief hunt for a good antonym of "coalesce" lands me on "fractionated". I like that better than the temporal implications (evoked in *me* even if nobody else) of divergent. The volume of space is *rationed* amongst the branches sprouted from a tree trunk, much like the volume of tissue is divied up amongst the sinusoids sprouted from the portal vein in the liver. And I can say the same thing about the other side. The tissue is fractioned/rationed/divied up amongst the sinusoids that lead into the liver's output.
Such a fractionated (fractioned? rationed? "binned"?) region can be talked about independent of the direction of flow. And this idea of divying up the space carries with it some sort of agency, functionality, or purpose beyond the more objective terms like plexus or plenum, which could be engineered or natural. Divied up how? Why? What is being optimized by tree branching, basin canalization, dendritic spreading, etc?

Very interesting.
In a rather different context, I was led to a word “apportionment”, which I think is similar in intent to your fractionation. The context was the inherent limitation of fitness as the term is used in population genetics, where it is required (by the roles it must play in Fisher’s Fundamental Theorem and the Price Equation) to be an apportionment. God, I wonder what it must be like to be a real writer, and have some kind of command of the richness of this thing called language that we have all inherited. > On Aug 21, 2018, at 2:33 PM, uǝlƃ ☣ <[hidden email]> wrote: > > Coalescence is a very nice sidetrack, actually.

∄ uǝʃƃ - I can't believe none of us offered up "plexus" along the way! I think your invocation of "bed" *IS* maybe better served by "plenum" and I can see how the portmanteau of plenum and nexus naturally arrive at "plexus" as suggested. Plenum seems to connote "mixing" not just collection/distribution whereas "bed" seems a bit more static. I always thought that the engineering use of "manifold" was
modestly disingenous, abusing the more abstract purity of the
mathematical "manifold". Propogating the engineering use into
biology would seem only to aggravate the abuse? Of course, this
*IS* how language evolves, so who am I to say? While I am most familiar with the obvious nerve-bundle plexuses (solar plexus, lumbar plexus, brachial plexus, sacral plexus, etc.) a little review on the internet shows that the term is also used in lymphatic and blood systems (collectively "veinous"?), including the blood-brain. The concept (word?) I have been in search of since you first
brought this up turns out to be "anastomose" which describes the
interconnection between networks (of possibly different
qualities?). https://en.wikipedia.org/wiki/Anastomosis I also encountered the term "reticulation" which might also be *structurally* relevant to what is happening in the "bed" or "plenum" you are considering? The following is one of the more compelling images I found regarding the Liver Lobules you are working with:  I do find the general structure/function study implied with the myriad networks interpenetrating here intriguing. Nerve, blood, lymph, both afferent and efferent do seem to interpenetrate throughout the body. More specialized structures (e.g. Liver) add yet more such as bile and the chemically different composition of blood flowing from liver to kidney vs heart to liver vs intestine to liver (etc.). The hepatic sinusoid you referenced is an interesting structure... or more to the point sinusoids throughout the many "filtering" or "exchange" tissues in the body. Fenestrated endothelium seems to be one of the significant mechanisms for the chemical "sorting" that goes on? Strangely, this function/structure study parallels a current fascination I have with the cross-boundary *human* networks involved in various at-risk populations in the world (opposite sides of the US border, including criminal/gang networks, but also family networks, aid organizations, etc... Middle East and North Africa refugee sources/sinks, and the current prison workers union/strike movements.... inside/outside the Catholic Church heirarchy/flock... etc.) Art imitates life? Life imitates life! - Steve On 8/21/18 7:50 AM, ∄ uǝʃƃ wrote:

In most computational modeling of phylogeny, there are not directional transformations (as the name "filtration" suggests), but reversible transformations of DNA in a genome (e.g. transitions/tranversions of purines/pyrimidines).

And I can say the same thing about the other side. The tissue is fractioned/rationed/divied up amongst the sinusoids that lead into the liver's output. Such a fractionated (fractioned? rationed? "binned"?) region can be talked about independent of the direction of flow. And this idea of divying up the space carries with it some sort of agency, functionality, or purpose beyond the more objective terms like plexus or plenum, which could be engineered or natural. Divied up how? Why? What is being optimized by tree branching, basin canalization, dendritic spreading, etc?

I don’t think the geneticists have a corresponding word for the final-time data that it is the purpose of the coalescent to assign a history to, but I guess the counterpart would be the “divergent”. That would have been a strange notion for a merely-concentrated part of a network that wasn’t both treelike and directed in some sense, so I stayed quiet. But it seems treelike networks with sources and destinations are still in the conversation. > > Of course this has the problem that both words are natively adjectives, themselves derived from transitive verbs, which have now been repurposed as nouns in technical fields. But maybe in linguistic typology that isn’t so uncommon (Bill Croft has told me this, but I don’t have a particularly good reference.
