Hydrogen-induced fast fracture in a 1.5 GPa dual-phase steel
This study clarifies the hydrogen embrittlement (HE) behavior in a 1.5 GPa ferrite-martensite dual-phase (DP) steel. Hydrogen pre-charging (3.8 mass ppm diffusible hydrogen), followed by slow strain tensile testing (10-4 s-1), resulted in a brittle fracture at 900 MPa within the elastic regime. Fractographic studies indicated that surface crack initiation consists of intergranular and quasi-cleavage morphology; site-specific transmission electron microscopy (TEM) investigations revealed sub-sur…

What are you going to do when the regime falls? After calling all your friends, after the great memes, after the parties, what are you going to do to make sure it never happens again? What world should we create?
Taxing billionaires is great and all, but we could build systems where billionaires are impossible. Is hoarding wealth and using it to control people even something we should consider part of a functional and humane system? Any system where one group of people doesn't have rights means that anyone can be stripped of their rights, like has happened with all the US citizens who've been illegally detained and deported by ICE. Does the concept of "rights" that must be defended with violence, that can be stripped away by people who can exercise more violence, even make sense? Or should the bedrock of a functional system be the obligations that we have to each other and to society, that cannot be severed or taken from us, that tell us we *must* defend regardless of whether systemic oppression will impact us or not?
Americans have been so restricted by the limitations of the two party system, only able to choose between options acceptable to different sections of the capitalist class. Would we even be able to imagine what we could do if those restrictions went away?
The fall of the Berlin wall was a surprise. The fall of Assad was faster than anyone expected. One day the government of Nepal was an unrepentant oligarchy, the next it was on fire. Everything can change in an instant, faster than anyone expects. No one can predict revolutionary change. Will you be ready if the opportunity presents itself?
The US cannot be fixed. The economic system is a ponzi scheme that has been patched again and again, but has finally run out of options. Racism, sexism, and Christian nationalism are baked into the system at every level. Trump gutted the system of soft power that held the US economy together, now there is only a slow decline. Even after he's gone, the damage is done. Once we let go of how to fix something that cannot be fixed, we can start to imagine something that cannot be achieved within the current system.
This is a time of opportunity. Do not burrow so deep in terror that you miss your chance to dream.

Dynamical Mechanism of Episodic Gas Accretion to the Central Region of Spiral Galaxies
We performed \textit{N}-body/SPH simulations of isolated spiral galaxies with various bulge-to-disk mass ratios ($M_{\rm bulge}/M_{\rm disk}$) from 0.02 to 0.2 to investigate mass transport from galactic scales (10 kpc) down to circumnuclear disk scales ($\lesssim$ 100 pc). Our analysis revealed these main findings, (1) Gravitational torque from stellar spiral arms causes gas accretion with $\sim1$ $M_\odot$ ${\rm yr}^{-1}$ along the gas spiral arms from a few kpc to a few 100 pc scale. The den…

Silicate clouds and a circumplanetary disk in the YSES-1 exoplanet system
Young exoplanets provide a critical link between understanding planet formation and atmospheric evolution. Direct imaging spectroscopy allows us to infer the properties of young, wide orbit, giant planets with high signal-to-noise. This allows us to compare this young population to exoplanets characterized with transmission spectroscopy, which has indirectly revealed the presence of clouds, photochemistry, and a diversity of atmospheric compositions. Direct detections have also been made for br…

Uspol, genocide
In case you're wondering whether "political violence" is escalating in the U.S.A. right now, of *course* it is as we move into an era of concentration campus and domestic military deployments. But both domestic genocides and purges as well as political violence targeted at individual prominent figures has been a *constant* throughout American history, from gun duels fought between political rivals to massacres of Native Americans in order to steal their land, to pogroms against Catholics, to literal wars on local Black success and political participation, all dating back before the American Revolution to the beginning of colonization. Thanks to Wikipedia, here's a *small sampling* where I attempted to whittle things down to about one event per decade before recent times.

Dense Molecular Ring-like structure in gaseous CO depletion region G34.74-0.12
We report the discovery of a dense molecular ring-like structure in a dense (10$^5$ cm$^{-3}$), cold (pc-scale CO depletion at a factor of 5), and young (10$^4$ year) star-forming region G34.74-0.12, revealed by C$^{18}$O (2-1), HNC (1-0), and N$_2$H$^+$ (1-0) observations with the Atacama Large Millimeter/submillimeter Array (ALMA). The ring-like structure is redshifted with respect to the clump, spanning from $V_{\rm sys,lsr} + 0.9$ to $V_{\rm sys,lsr} + 2.9$ km s$^{-1}$, with a total mass of…
