I didn't realize so many Quick Build projects were failing this badly to reduce injury crashes. On some of these streets I *feel* safer since the changes, but the numbers don't lie. These are failures and SF must reevaluate its whole approach. Concrete > flex posts

Deficit Angles in 4D Spinfoam with Cosmological Constant: (Anti) de Sitter-ness and More
This paper investigates the critical behaviors of the 4-dimensional spinfoam model with cosmological constant for a general 4-dimensional simplicial complex as the discretization of spacetime. We find that, at the semi-classical regime, the spinfoam amplitude is peaked at the real critical points that correspond to zero deficit angles (modulo $4π\mathbb{Z}/γ$) hinged by internal triangles of the 4-complex. Since the 4-simplices from the model are of constant curvature, the discrete geometry w…

The Sun Remains Relatively Refractory Depleted: Elemental Abundances for 17,412 Gaia RVS Solar Analogs and 50 Planet Hosts
The elemental abundances of stars, particularly the refractory elements (e.g., Fe, Si, Mg), play an important role in connecting stars to their planets. Most Sun-like stars do not have refractory abundance measurements since obtaining a large sample of high-resolution spectra is difficult with oversubscribed observing resources. In this work we infer abundances for C, N, O, Na, Mn, Cr, Si, Fe, Ni, Mg, V, Ca, Ti, Al, and Y for solar analogs with Gaia RVS spectra (R=11,200) using the Cannon, a da…

Someone asked today what a 'sense of self' is.
I want to tie this into ideas of relationality. I am a distinct individual, let's start with that. I'm not disavowing that entirely.
But I am also ‘an unschooler’: but this is not an attribute of my education for comparison. It is a community, a network of relationships with people working in similar ways. It's connections to anabaptist traditions and to a mode of interacting with parents (both in concept and my actual parents)
I'm from Colorado. But it's not just a place on the map: it's my relationship to my sense of smell, and my tolerance for cold weather and bright lights. It's a love of dark skies and clear views of the milky way. It's a relationship to knowing I am very very small in a vast universe. This is not a universal explanation of from-Colorado-ness, but it's mine.
I'm transgender, but that's not just I-myself-was-born-in-a-wrong-body, but I have a community and network and sense of belonging outside of myself. I've got embodied knowledge of being a dozen ways that others don't get to experience. It affects and informs my relationship to my communities and my work.
I’m argumentative and sometimes a little arrogant, but this is also because of how I'm connected: there are things I know deep in my body that I cannot explain how I know, but I do. I forget that others see me as a ‘you' and not a 'we' sometimes, and so misunderstandings happen. But to change that would change me in ways I'm not quite willing to grow into, so there is going to be a small callus in how I socialize. And it's fine. It works. I am who I am, but I also don't think about _me_ that much. To think about me is to think of all the connections instead. They're inseparable.

Don Rafa's at 16th Street / South Van Ness is lowkey a great bike shop. Only open Mon-Fri and in a weird spot to bike to, but good people. Came in for a flat fix and they noticed my chain was dry and oiled it just as a courtesy #bikeSF

Interpretable Prediction and Feature Selection for Survival Analysis
Survival analysis is widely used as a technique to model time-to-event data when some data is censored, particularly in healthcare for predicting future patient risk. In such settings, survival models must be both accurate and interpretable so that users (such as doctors) can trust the model and understand model predictions. While most literature focuses on discrimination, interpretability is equally as important. A successful interpretable model should be able to describe how changing each fea…

After a child was killed by a turning driver at 4th & King, Mayor Breed said the city would look at closing all double turn lanes.
That was August. SFMTA is still individually analyzing every intersection to see whether fixing a known unsafe design would back up cars.
Why don't they come out and say what the exchange rate is for vehicle delay minutes <=> human lives?
