Most oceans over the globe have experienced surface warming during the past century,
but the subpolar Atlantic is quite otherwise.
The sea surface temperature cooling trend to the south of Greenland,
-- known as the North Atlantic Warming Hole,
-- has raised debate over whether it is driven by the slowing of the Atlantic Meridional Overturning Circulation.
Here we use observations as a benchmark and climate models as a tool to demonstrate that only models sim…

Weakened Atlantic Meridional Overturning Circulation causes the historical North Atlantic Warming Hole - Communications Earth & Environment
The North Atlantic Warming Hole is tied to a weakened Atlantic Meridional Overturning Circulation during the past century, according to climate models and observation data.

The second order Huang-Yang approximation to the Fermi thermodynamic pressure
We consider a dilute Fermi gas in the thermodynamic limit with interaction potential scattering length $\mathfrak{a}_0$ at temperature $T>0$. We prove the 2nd order Huang-Yang approximation for the Fermi pressure of the system, in which there is a 2nd order term carrying the positive temperature efffect.Our formula is valid up to the temperature $T<ρ^{\frac{2}{3}+\frac{1}{6}}$, which is, by scaling, also necessary for the Huang-Yang formula to hold. Here, $T_F\simρ^{\frac{2}{3}}$ is the Fermi…

Rather surprised to see the performance scaling of nftables is so bad compared to iptables, especially as many distros switched to nftables by default some time ago.
I do understand that synthetic benchmarks of firewalls are difficult, and that you are supposed to use the advanced features of nftables (e.g. sets, maps) to express the same filter in fewer rules.

Trump order could end Chinese drone sales in the U.S.
The Trump administration is finalizing executive orders that could lead to Chinese drone-makers like DJI being barred from selling new models in the US.

Flowing from the Ising Model on the Fuzzy Sphere to the 3D Lee-Yang CFT
We employ the Fuzzy Sphere regulator to study the 3D Lee-Yang CFT. The model is defined by deforming the Ising model on the Fuzzy Sphere via a purely imaginary longitudinal magnetic field. This model undergoes a quantum phase transition, whose critical point we determine and identify with the 3D Lee-Yang CFT. We show how to tune the model and find that the lowest-lying states of the Hamiltonian align well with the expected CFT spectrum. We discuss the Fuzzy Sphere estimates for the scaling dime…

"Because I deserved support in that moment. I deserved having my boss taking me to the side to have a coffee and asking me how I was doing. I deserved having somebody more in my team to help me figure out a new technical solution for that project, instead of leaving me alone. I deserved having a product owner communicating issues to that customer. I deserved having someone giving a fucking shit about my mental health."

Radio Silence
I have had three episodes of burnout in my professional life, in three consecutive years.

Selenskyj fordert erneut Druck auf Russland
Der ukrainische Präsident Wolodymyr Selenskyj hat bei einem Treffen mit den US-Senatoren Lindsey Graham und Richard Blumenthal in Kiew seine Hoffnung auf schärfere Sanktionen gegen Russlands Kriegsmaschinerie bekräftigt. Er sei dankbar für die neue US-Sanktionsinitiative, die von 82 Senatoren unterstützt werde, teilte Selenskyj auf der Plattform X mit. Es brauche mehr Druck auf Russ…
