The privately funded National Trust for Historic Preservation last week asked the U.S. District Court to block Trump’s project.
“No president is legally allowed to tear down portions of the White House without any review whatsoever
— not President Trump, not President Biden, and not anyone else,” the lawsuit states.
“And no president is legally allowed to construct a ballroom on public property without giving the public the opportunity to weigh in.”

Trump administration says White House ballroom construction is a matter of national security
The Trump administration says in a court filing that the president’s White House ballroom construction project must continue for unexplained national security reasons. It also says a preservationists’ organization that wants it stopped has no standing to sue. The court filing Monday was in response to a lawsuit filed last Friday by the National Trust for Historic Preservation asking a federal judge to halt President Donald Trump’s project until it goes through multiple independent reviews…

Anatomy of a crypto meltdown
October 2025 brought the most dramatic crypto flash crash of all time, but it was only a dress rehearsal for the systemic crisis the industry is building toward.

Classification Filtering
We consider a streaming signal in which each sample is linked to a latent class. We assume that multiple classifiers are available, each providing class probabilities with varying degrees of accuracy. These classifiers are employed following a straightforward and fixed policy. In this setting, we consider the problem of fusing the output of the classifiers while incorporating the temporal aspect to improve classification accuracy. We propose a state-space model and develop a filter tailored for…

Normalized solutions to Kirchhoff equation with the Sobolev critical exponent in high dimensional spaces
The following well-known Kirchhoff equation with the Sobolev critical exponent has been extensively studied, \begin{equation*} -\Big(a+b\int_{\mathbb R^N} | \nabla u|^2dx\Big) Δu+λu=μ|u|^{q-2}u+|u|^{2^*-2}u \ \ {\rm in}\ \ \mathbb{R}^N, \ \ N\geq4, \end{equation*} having prescribed mass $\int_{\mathbb R^N}|u|^2dx=c$, where $a$, $c$ are two positive constants, $b,μ$ are two parameters, $λ$ appears as a real Lagrange multiplier and $2

So I grew up next to #Chernobyl and this is, well, TERRIFYING.
A story for y’all: I’m from a city called Zhytomyr, 2 hours west of Kyiv in the North of #Ukraine. We were downwind of the Chernobyl #nuclear power plant when the 1986 disaster happened.
I wasn’t born for another 12 years, but my childhood was filled with stories and the aftermath of it all. Things like:
- My grandmother worked as a head doctor in a hospital and rehabilitation facility exclusively for children of Chernobyl victims to treat the extremely high prevalence of Tuberculosis and other severe health complications. (To specify: these were SECOND GENERATION of exposure).
- A lot of the kids in that facility were orphans, because their parents died young from health problems.
- My uncle’s wife was born in Pripyat. She was 1 year old when the disaster happened. Her parents were told to evacuate while given no information about what happened. They had to pack up their things and rush out to an unfamiliar city with their baby, never to see the rest of their belongings, apartment, or hometown again.
- When I was a kid, it became so common to see weirdly mutated animals and insects that even 2-3 year olds would make jokes about “Chernobyl mosquitos” and I wouldn’t even flinch seeing occasional giant bugs, dark frogs, weird-looking dogs.
- We’d frequently hear of nearby farms having issues with their animals being born too mutated to survive or random outbreaks from contaminated water / food. Crops would randomly fail. People would get poisoned on a regular basis. This all got less common as I grew up.
- My mother still remembers being a little girl, 10 years old, and looking outside from their balcony at the clouds blowing over from Chernobyl that day. People were told to not go outside and to shut all the windows, but not given an explanation as to why. My mother swears that the rain looked different. They weren’t able to go and buy more food for the kitchen for multiple days.
Anyway - nuclear safety isn’t a joke. I don’t understand how this level of carelessness can happen after Chernobyl and Fukushima.

Observation Matrix Design for Densifying MIMO Channel Estimation via 2D Ice Filling
In recent years, densifying multiple-input multiple-output (MIMO) has attracted much attention from the communication community. Thanks to the subwavelength antenna spacing, the strong correlations among densifying antennas provide sufficient prior knowledge about channel state information (CSI). This inspires the careful design of observation matrices (e.g., transmit precoders and receive combiners), that exploits the CSI prior knowledge, to boost channel estimation performance. Aligned with t…

The president of the United States is invading multiple US cities and liberal strongholds, in troop deployments that are now the primary component of his vast, lawless, smash-and-grab efforts to shred the nation’s constitutional and democratic order, all in the service of his personality cult.
And his enthusiasm for doing so is partially, and meaningfully, fueled by how mad he gets while binge-watching hours and hours of TV, current and former Trump advisers tell Zeteo.

Trump’s Addiction to Watching Fox Is Killing American Democracy
Our country is falling apart because one old man, Trump advisers and former administration officials say, won’t stop ‘yelling’ at his TV.

Multiple sign-changing solutions for semilinear subelliptic Dirichlet problem
We study the following perturbation from symmetry problem for the semilinear subelliptic equation \[ \left\{ \begin{array}{cc} -\triangle_{X} u=f(x,u)+g(x,u) & \mbox{in}~Ω, \\[2mm] u\in H_{X,0}^{1}(Ω),\hfill \end{array} \right. \] where $\triangle_{X}=-\sum_{i=1}^{m}X_{i}^{*}X_{i}$ is the self-adjoint sub-elliptic operator associated with Hörmander vector fields $X=(X_{1},X_{2},\ldots,X_{m})$, $Ω$ is an open bounded subset in $\mathbb{R}^n$, and $H_{X,0}^{1}(Ω)$ denotes the weigh…
