New publication: Glued forever: incomplete #dispersion hampers #POM-#MAOM #fractionation in #soils with high SOC and metal (hydr)oxide content.

Four timesteps from the final 7 seconds before #Venus vanished behind a distant roof structure today: each image 1/3.2 second at f/2.8 and ISO 400 with maximum digital zoom yielding an equivalent focal length of about 3 meters, pictures in full resolution and cropped, no further processing. The spectral #dispersion is clearly visible; unfortunately Venus 'hit' the structure from the side, so cutting off the red and leaving only the green/blue upper part as in https://spaceweathergallery2.com/indiv_upload.php?upload_id=231191 didn't happen. #AtmosphericalOptics

Spores Get a Lift
Mushrooms have the challenging task of dispersing spores, typically from heights no more than a few centimeters above the ground. At that altitude, viscosity and friction with the ground mean that air barely moves, if it does at all. And mushrooms rely on a wide range of methods, from explosive launches to rain assistance to making their own weather. Every one of these methods gives spores a lift in altitude to reach higher winds and greater dispersal. (Image credit: A. Bejczi/CUPOTY; via Colossal)

By inserting an artificial word with precisely defined frequency and #dispersion, they test how well different measures detect what’s truly #distinctive.
Their findings uncover that a #TF-IDF -based measure is more sensitive to dispersion variations than other dispersion-based measures. #Evaluation

Hype for the Future 12/284: Concerns with the Future
novaTopFlex is getting nervous about losing the vast majority of a social circle naturally built from just a few years of common experience. Any help would be gladly appreciated from any individual or group who has missed any group(s) elsewhere.

“Dispersion”
In “Dispersion,” particles spread under the influence of an unseen fluid. Like Roman de Giuli’s work, filmmaker Susi Sie creates macro images that look like ice floes, deserts, and river deltas viewed from above. This similarity of patterns at both large and small scales is a specialty of fluid physics. Just as artists use it to mimic larger flows, scientists use it to study planet-scale problems in the lab. (Video and image credit: S. Sie et al.)

Paradójicamente, las evidencias empíricas demuestran que las ciudades con infraestructuras diseñadas para mayores velocidades no presentan menores tiempos totales de desplazamiento.
Esta contradicción sugiere que los habitantes de entornos urbanos ajustan sus patrones de desplazamiento a las condiciones disponibles, pero el factor tiempo permanece relativamente constante.
La diferencia radica en que los sistemas de mayor velocidad fomentan distancias más largas, sin reducir efectivamente el tiempo dedicado a desplazamientos.
Es uno de los motivos por los cuales construir carreteras conduce a la #dispersión urbana.

Jetzt läuft unser Vortrag bei der #Dhd2025 den Julia Dudar hält: "Untersuchung von Distinktivitätsmaßen: Eine Evaluation anhand von synthetischen Texten".
Grundidee: Mehrere #Keyness-Maße werden auf der Grundlage von synthetischen Texten (ohne signifikante Unterschiede der Textgruppen) auf ihre Sensitivität auf Unterschiede von #Häufigkeit einerseits, #Dispersion andererseits hin evaluiert.
Ergebnis: Unterschiedliche Maße sind sehr unterschiedlich sensitiv!

"La lutte sociale, ça nécessite de l’orga. Et, plus que jamais, on a besoin d’outils fiables pour s’organiser. Au choix, entre m’organiser au McCafé ou dans un bar géré par des meufs trans, c’est vite choisi. Insta est aliénant. Swiper n’est pas un geste militant. C’est déprimant et ça nous nique notre capacité de concentration. Ça nous habitue à des intéractions superficielles et constamment avoir le regard potentiel de 500 personnes est hyper anxiogène. La discrétion c’est important pour s’organiser."

Viral #shedding & environmental #dispersion of 2 clade 2.3.4.4b #H5 #HPAI viruses in experimentally infected mule #ducks: implications for environmental sampling, Vet Res.: https://veterinaryresearch.biomedcentral.com/articles/10.1186/s13567-024-01357-z
Our results confirm that mule ducks can shed high HPAIV titres through the four excretion routes tested (oropharyngeal, cloacal, conjunctival, and #feather) while being asymptomatic and that environmental sampling could be a non-invasive tool for early viral RNA detection in HPAIV-infected #farms.

In the Way of Inquiry • Objections to Reflexive Inquiry 2
• https://inquiryintoinquiry.com/2023/02/05/in-the-way-of-inquiry-objections-to-reflexive-inquiry-a/Our agent of inquiry is brought to the threshold of two questions:
• What actions are available to achieve the aims of the present activity?
• What assumptions already accepted are advisable to amend or abandon?
The inquirer is faced in the object of inquiry with an obstinately oppositional state of affairs, a character marked by the Greek word “pragma” for “object”, whose manifold of senses and derivatives includes among its connotations the ideas of purposeful objectives and problematic objections, and not too incidentally both inquiries and expositions.

In the Way of Inquiry • Objections to Reflexive Inquiry 1
• https://inquiryintoinquiry.com/2023/02/05/in-the-way-of-inquiry-objections-to-reflexive-inquiry-a/Inquiry begins when an automatic routine or normal course of activity is interrupted and agents are thrown into doubt concerning what is best to do next and what is really true of their situation. If this interruptive aspect of inquiry applies at the level of self‑application then occasions for inquiry into inquiry arise when an ongoing inquiry into any subject becomes obstructed and agents are obliged to initiate a new order of inquiry in order to overcome the obstacle.
At such moments agents need the ability to pause and reflect — to accept the interruption of the inquiry in progress, to acknowledge the higher order of uncertainty obstructing the current investigation, and finally to examine accepted conventions and prior convictions regarding the conduct of inquiry in general. The next order of inquiry requires agents to articulate the assumptions embodied in previous inquiries, to consider their practical effects in light of their objective intents, and to reconstruct forms of conduct which formerly proceeded through their paces untroubled by any articulate concern.

Key take-aways for me so far from Stefan Gries' talk:
We should be using "pure" measures that only measure one thing, so that they are valid. Measures that intransparently conflate two or several aspects are not as useful as they could be.
We need multiple dimensions to fully describe a word's characteristics, but they need to be independent of each other / uncorrelated (see above), for it to make sense to "tupleize" them.

Very happy to be in #Montpellier today for a "journée d'étude" on the notion of #tupleization in the context of #cooccurrence, #keyness, #frequency and #dispersion. – The opening speaker is Stefan Th.

#Dispersion of #woke #brilliance in 17th century:
1. #White is but a mix of #color in #harmony.
2. Difference between #straight #white and #Uranian #pride is sometimes a matter of #perception and the #prism one is looking through.

Uno de los conceptos más complicados de explicar en urbanismo, #dispersión sobre el territorio y dependencia del automóvil es el hecho de que la necesidad de usar este último deriva de la infraestructura dada.
Infraestructura → Necesidad
En el imaginario colectivo una familia 'necesita' usar el coche, y entonces por ello hay que tender más carreteras o permitir su presencia en todas las calles. Es un concepto erróneo formulado porque tendemos a dar la infraestructura como algo que está, algo estático e invariable. (Y neutro)
Lo contrario sí es cierto. Dada una infraestructura, una familia enerará necesidades en función de esta.

Los países ubicados en la zona alta del gráfico, entre los que se incluye Singapur, Emiratos Árabes Unidos, Arabia Saudí o Bélgica, han desarrollado sociedades con consumos basales (consumos mínimos para funcionar) enormes. Son países que han creado sistemas en los que para hacer algo que en otro país apenas emite, libera una cantidad bestial de CO2. Y sí, en parte se debe al #urbanismo, el #cochecentrismo y la #dispersión urbana.
