Why is Wall Street brushing off Trump’s escalating tariff threats?
Investors feel free to continue bidding up stock prices because they assume TACO Trump will always back down from his most costly tariff plans, market analysts said.
But Trump views stocks’ steady rise as a license to intensify his trade threats,
acting out the economic policy equivalent of his 2016 quip that he could “stand in the middle of Fifth Avenue and shoot somebody” without paying a price.

Why Wall Street is brushing off Trump’s escalating tariff threats
President Donald Trump’s escalating tariff threats have not deterred Wall Street, with the stock market continuing to rise despite trade policy uncertainty.

The White House has seized on two unrelated incidents of street crime
as a pretext for a federal government power grab
at a time when violent crime has in fact dropped across the country.
The attempted carjacking of Edward “Big Balls” Coristine in Washington DC
and a street brawl in Cincinnati
are the latest cause célebrè on the American right,
which has long supported Donald Trump’s plans for military and law enforcement crackdowns in largely Democratic c…

Crime is down. But Trump's authoritarian power grabs are escalating.
Random street crimes are being used as pretexts for repression.

Curves with increasing chords in normed planes
A curve has the increasing chord property if for any points $a,b,c,d$ in this order on the curve, the distance of $a,d$ is not smaller than that of $b,c$. Answering a conjecture of Larman and McMullen, Rote proved in 1994 that the arclength of a curve in the Euclidean plane with the increasing chord property is at most $\frac{2π}{3}$ times the distance of its endpoints, and this inequality is sharp. In this note we generalize the result of Rote for curves in a normed plane with a strictly conv…

Cuban President Miguel Diaz-Canel strongly condemned the US bombing, saying it constituted a “dangerous escalation” and a serious violation of the UN Charter.
He added that it “plunges humanity into a crisis with irreversible consequences”.

Rigidity of solitons of the Gauss curvature flow in Euclidean space
In this paper, we consider $λ$-translating solitons and $λ$-shrinkers of the Gauss curvature flow in Euclidean space. We prove that planes and circular cylinders are the only $λ$-translating solitons with constant mean curvature. We also prove that planes, spheres and circular cylinders are the only $λ$-shrinkers with constant mean curvature. We give a classification of the $λ$-translating solitons and $λ$-shrinkers with one constant principal curvature.

Fokker-Planck Score Learning: Efficient Free-Energy Estimation under Periodic Boundary Conditions
Accurate free-energy estimation is essential in molecular simulation, yet the periodic boundary conditions (PBC) commonly used in computer simulations have rarely been explicitly exploited. Equilibrium methods such as umbrella sampling, metadynamics, and adaptive biasing force require extensive sampling, while non-equilibrium pulling with Jarzynski's equality suffers from poor convergence due to exponential averaging. Here, we introduce a physics-informed, score-based diffusion framework: by ma…

Euclid: Early Release Observations. A combined strong and weak lensing solution for Abell 2390 beyond its virial radius
Euclid is presently mapping the distribution of matter in the Universe in detail via the weak lensing (WL) signature of billions of distant galaxies. The WL signal is most prominent around galaxy clusters, and can extend up to distances well beyond their virial radius, thus constraining their total mass. Near the centre of clusters, where contamination by member galaxies is an issue, the WL data can be complemented with strong lensing (SL) data which can diminish the uncertainty due to the mass…

Calibrated submanifolds with flat normal bundles
We show that submanifolds of Euclidean space which are calibrated by a constant-coefficient differential form and have flat normal bundles are planes. In fact, in a Riemannian manifold equipped with a parallel calibration, a calibrated submanifold subject to the condition that all shape operators commute is totally geodesic.

Stationary surfaces for the moment of inertia with constant Gauss curvature
Consider the energy $E_α[Σ]=\int_Σ|p|^α\, dΣ$, where $Σ$ is a surface in Euclidean space $\r^3$ and $α\in\r$. We prove that planes and spheres are the only stationary surfaces for $E_α$ with constant Gauss curvature. We also characterize these surfaces assuming that a principal curvature is constant or that the mean curvature is constant.
