Spotted in a #CaptainAmerica story in #TalesofSuspense c1966: "he dived" rather than "he dove" to describe the actions of #RedSkull. As far as their use in literature, the latter only became more common in the 1980s (books.google.com/ngrams/graph?). As someone born in the 1980s, "dived" does sound really strange.

Fluvial System Block Diagrams
--
I was looking to understand a fluvial system the other day, up in the high Arctic, as I looked at 3DEP remote sensed elevation data… I have always been fascinated by the how geology, water, weather shapes a landscape, including erosion (aka geomorphology if you will) – and realized how very much value fluvial block diagrams have as we try to conceptualise what has, is and will happen(ed.)

The "Korean Journal of Digital Humanities" (under the aegis of #KADH) has just published a new issue! accesson.kr/kjdh/v.1/2/2024

Wide range of topics, including a short story #dataset, an analysis of #Fitzgerald, #newspaper, #networks, #morphology...

... and, intriguingly and curiously, an interview with myself.

A major criticism is that the technique of high-pressure freezing only handles very small volumes at most 200 micrometers thick, and therefore, the tissue being from a mouse brain, a significant amount of injury to neuronal arbours was caused to generate such small samples.

Three kinds of samples were used:
(1) Cell culture neurons, which have their own problems and can't be considered authoritative on neuronal morphology.
(2) Hippocampal slices, which do recover from sectioning when in the right culture medium but only to some extent. Most neurons exist as fragments in the slice. Artifacts in morphologies are expected.
(3) Acutely extracted brain bits can't be immediately frozen; even a second is enough for neurons to fire and osmolarity to shape neuronal morphologies away from the natural state.

In summary: while surely neurons in their natural state don't look like those in textbooks, since all sample preparations suffer from artifacts, I am not convinced that this study resolves the issue. Try to freeze a small animal – like it's been done for C. elegans. Do these peculiar axon morphologies exist in the HFP'ed worm?

The authors themselves admit that:
"treatments that disrupt these parameters like hyper- or hypo-tonic solutions, cholesterol removal, and non-muscle myosin II inhibition all alter the degree of axon pearling" – and all of these come into play during sample preparation.

I wish the reviews were published. Andreas Prokop, a neuroscientist working on microtubules in neurons, was involved, which is reassuring.

📢New Publication Alert!

📚 Explore the linguistic treasure trove of #Jibbali/#Śḥərɛ́t. Giuliano Castagna delves into this endangered language, preserving its rich #proverbs and #idioms for future generations.

This book explores the rich paremiological heritage of #Jibbali/#Śḥərɛ̄́t, an endangered pre-literate language belonging to the Modern #SouthArabian sub-branch of #Semitic, spoken by an ever-decreasing number of people in the #Dhofar governorate of the Sultanate of Oman.

Reflecting the historical value of #proverbs and #idiomatic expression within the documentation of a language, Giuliano Castagna analyses a sizeable share of #Jibbali/#Śḥərɛ̄́t #proverbs, sayings and idioms from #Arabic-language publications, as well as hitherto unpublished expressions that reveal undocumented features in the domains of #lexicon, #phonetics, #phonology and #morphology.
