But that’s not the endpoint. Oh no.
In a move alarmingly close to outright chattel slavery, there is talk of ICE capturing immigrants and then •selling them back to their former employers•, presumably under much-worsened employment conditions.

Heterogeneous response and non-Markovianity in the microrheology of semisolid viscoelastic materials
Recent works indicate that heterogeneous response and non-Markovianity may yield recognizable hallmarks in the microrheology of semisolid viscoelastic materials. Here we perform numerical simulations using a non-Markovian overdamped Langevin approach to explore how the microrheology experienced by probe particles immersed in an effective semisolid material can be influenced by its micro-heterogeneities. Our results show that, besides affecting the mean squared displacement, the time-dependent d…

Superatomic hydrogen: achieving effective aggregation of hydrogen atoms at pressures lower than that of metallic hydrogen
Metal hydrogen exhibiting electron delocalization properties has been recognized as an important prospect for achieving controlled nuclear fusion, but the extreme pressure conditions required exceeding hundreds of GPa remain a daunting challenge. Here, we propose a model of superatomic hydrogen, aiming to reduce the pressure conditions required for the effective aggregation of elemental hydrogen atoms. High-precision ab initio calculations indicate that the pressure required to compress the H13…

Nonlinear elastodynamic material identification of heterogeneous isogeometric Bernoulli-Euler beams
This paper presents a Finite Element Model Updating framework for identifying heterogeneous material distributions in planar Bernoulli-Euler beams based on a rotation-free isogeometric formulation. The procedure follows two steps: First, the elastic properties are identified from quasi-static displacements; then, the density is determined from modal data (low frequencies and mode shapes), given the previously obtained elastic properties. The identification relies on three independent discretiza…

Running cars on E-Fuels, made with CO2 from the air and green Hydrogen?🚗⛽🌿⚡
E-Fuels, so the story goes, could allow using existing cars and infrastructure like gas stations. However, E-Fuels are extremely inefficient.
In 2022, Siemens Energy, Porsche, and the Chilean company HIF inaugurated the Haru Oni pilot plant in Chile's windy Magallanes region, which turns CO2 and Hydrogen into Methanol and small amounts of Gasoline. How's it going? 🧵

What's up with the Production of E-Fuels in Chile?
In 2022, Siemens Energy, Porsche, and HIF inaugurated a pilot plant for the production of E-Methanol and E-Gasoline in southern Chile. The Haru Oni plant was intended to be just the beginning — with plans for large-scale production just a few years later. However, it does not look like that will ever happen.

The South Coast Air Quality Management District will hold a public hearing Friday on two proposed regulations designed to limit key pollutants that form smog.
If adopted, the rules would phase out the sale of gas-powered furnaces and water heaters in the region.
Officials say the plan is crucial for reducing air pollution and improving public health, while opponents fear higher consumer costs.

Regulators seek to phase out gas-powered appliances in Southern California
The South Coast Air Quality Management District is poised to vote on regulations that would limit emissions of nitrogen oxides — the key pollutants that form smog.
