In April Todd Lyons,
the acting director of Immigration and Customs Enforcement (ice),
lamented that it takes too long to deport illegal immigrants.
At the Border Security Expo in Phoenix he told a crowd of startup bosses vying for government contracts that a better deportation system would function more like Amazon, the tech giant whose delivery drivers zigzag the country at record speed.
“Like Prime, but with human beings,” he said.

America’s immigration detention centres are at capacity
A visit to the second biggest, in Georgia, shows what that looks like

Lensing Without Borders: Measurements of galaxy-galaxy lensing and projected galaxy clustering in DESI DR1
We present Galaxy-Galaxy Lensing measurements obtained by cross-correlating spectroscopically observed galaxies from the first data release of the Dark Energy Spectroscopic Instrument (DESI) with source galaxies from the Hyper Suprime-Cam Subaru Strategic Survey, the Kilo-Degree Survey, the Sloan Digital Sky Survey, and the Dark Energy Survey. Specifically, we measure the excess surface mass density $ΔΣ$ and tangential shear $γ_\mathrm{t}$ for the Bright Galaxy Sample and Luminous Red Galaxi…

Mixing Time Bounds for the Gibbs Sampler under Isoperimetry
We establish bounds on the conductance for the systematic-scan and random-scan Gibbs samplers when the target distribution satisfies a Poincare or log-Sobolev inequality and possesses sufficiently regular conditional distributions. These bounds lead to mixing time guarantees that extend beyond the log-concave setting, offering new insights into the convergence behavior of Gibbs sampling in broader regimes. Moreover, we demonstrate that our results remain valid for log-Lipschitz and log-smooth t…

Bordered contact invariants and half Giroux torsion

Bordered contact invariants and half Giroux torsion
We show that there exist infinitely many closed contact 3-manifolds containing half Giroux torsion along a separating torus whose contact invariants do not vanish. This provides counterexamples to Ghiggini's conjecture and suggests that separating half Giroux torsion may not obstruct symplectic fillability. The main tools are the bordered contact invariants recently developed by the authors and the innermost contact structures on knot complements. We also show that there exists a closed contact…

Four years after Gov. Greg Abbott announced Texas would be the first state to build its own border wall, lawmakers have quietly stopped funding the project, leaving only scattered segments covering a small fraction of the border.
That decision, made in the waning hours of this year’s legislative session,
leaves the future of the state wall unclear.
Just 8% of the 805 miles the state identified for construction is complete, which has cost taxpayers more than $3 billion to dat…

With only 8% built, Texas quietly defunds state border wall program
Texas officials suggested the federal government could pick up construction. However, during President Trump’s first term, his administration built about one-third of what the state was able to put up in the same amount of time.

Heterogeneous Exposures to Systematic and Idiosyncratic Risk across Crypto Assets: A Divide-and-Conquer Approach

Heterogeneous Exposures to Systematic and Idiosyncratic Risk across Crypto Assets: A Divide-and-Conquer Approach
This paper analyzes realized return behavior across a broad set of crypto assets by estimating heterogeneous exposures to idiosyncratic and systematic risk. A key challenge arises from the latent nature of broader economy-wide risk sources: macro-financial proxies are unavailable at high-frequencies, while the abundance of low-frequency candidates offers limited guidance on empirical relevance. To address this, we develop a two-stage ``divide-and-conquer'' approach. The first stage estimates ex…

Experimental Assessment of A Framework for In-body RF-backscattering Localization
Localization of in-body devices is beneficial for Gastrointestinal (GI) diagnosis and targeted treatment. Traditional methods such as imaging and endoscopy are invasive and limited in resolution, highlighting the need for innovative alternatives. This study presents an experimental framework for Radio Frequency (RF)-backscatter-based in-body localization, inspired by the ReMix approach, and evaluates its performance in real-world conditions. The experimental setup includes an in-body backscatte…

Fears of racial profiling rise as Border Patrol conducts ‘roving patrols,’ and detain U.S. citizens
video: “These guys, literally based off of skin color! My homie was born here!” The friend said Gavidia was being questioned “just because of the way he looks.”
U.S. Border Patrol Sector Chief Greg Bovino,
who oversaw raids that included picking people up at Home Depot
and stopping them on the highway,
has emerged as a key figure in L.A.
He stood alongside…

Fears of racial profiling rise as Border Patrol conducts 'roving patrols,' detains U.S. citizens
Border Patrol agents on 'roving patrol' arrest U.S. citizen on assault charges. Fear of widespread racial profiling gains momentum as Home Depots and car washes raided.
