Effect of the degree of an initial mutant in Moran processes in structured populations
We study the effect of the mutant's degree on the fixation probability, extinction and fixation times, in the Moran process on Erdös-Rényi and Barabási-Albert graphs. We performed stochastic simulations and use mean-field type approximations to obtain analytical formulas. We showed that the initial placement of a mutant has a significant impact on the fixation probability and extinction time, while it has no effect on the fixation time. In both types of graphs, an increase in the degree of a…

Fictional depiction of mild self-harm, blood.
#WritersCoffeeClub July 23: Share a description you're proud of.
I've been writing a vampire novel lately. Here's a description from the scene when the vampire character proves to the human protagonist that he's been telling the truth:
—
"It's okay, Ada," he gave me a reassuring close-mouthed smile. "Just watch."
He slashed across his wrist in a motion that made the matching scars on my left arm hum. I covered them with my right hand, as if to calm my skin that I wasn't hurting it like that anymore. That we were merely watching someone else.
The cut on Theodore's arm turned red and angry, as expected. And then, just before the wound pooled up enough to bleed, it closed. I watched time run backwards as it disappeared, the skin stitching itself together to leave no trace of the violence imposed on it by the blade.
"What?" I walked up to him as he handed his wrist to me for inspection. I ran the tips of my fingers over the spot where the cut was mere moments before - but Theodore's skin, cold as always, was smooth and unharmed.

Faceting transition in aluminum as a grain boundary phase transition
Grain boundaries facet due to anisotropic grain boundary energies: While the faceted boundary has a larger area than the corresponding straight boundary, a significantly lower energy of the facets compared to a straight segment can drive the faceting. This picture is complicated by faceting/defaceting transitions where the free energy difference between the two states depends on the temperature. Here, we use atomistic computer simulations to show how such a transition in a $Σ3$ $[11\overline{1…

In Jason Henderson's 2013 book Street Fight he writes of SF transportation politics as a function of 3 factions: conservatives, neoliberals, progressives. How the street fights go depends on how those factions align. If you slot in YIMBYish urbanist types—those who are pro-bike, pro-business, believe that Dean Preston was blocking housing—as the neoliberals, this holds up surprisingly well today.

The FBI, headed by Trump acolyte Kash Patel, has reassigned the jobs of thousands of agents
and eviscerated parts of the bureau tasked with investigating rightwing extremists that are considered the most dangerous domestic security threat facing the US today.
Those same types, which includes a locus of fascist street-fighting gangs known as active clubs and accelerationist neo-Nazis,
increasingly view Trump as an enemy,
but are freer than ever to organize

Using Signal groups for activism
Things are heating up. Millions of people are taking to the streets against Trump's rising authoritarianism. Communities around the US are organizing to defend against ICE raids, to protest Israeli genocide, for mutual aid, and for other forms of fighting fascism. Signal can help people safely organize in all of
