White House continues East Wing demolition amid cries of Trump overreach (Washington Post)

This widely-linked story is, I think, much ado about nothing. Anyone who's seen the inside of an Amazon warehouse immediately thinks “Shouldn’t robots be doing this?” and that includes every Amazon biz and engineering leader, starting like 25 years ago. There is no doubt that the whole warehouse sector would love to replace humans with robots. It’s hard. So what’s new? Is it possible LLM fairy dust will solve the problem? Unconvinced.

Amazon hopes to replace 600,000 US workers with robots, according to leaked documents
Amazon is leaning into automation plans that will enable the company to avoid hiring more than half a million US workers, according to leaked documents.

Efficient Heuristic Algorithms for Interleaving Distance between Merge Trees
Merge trees are fundamental structures in topological data analysis. Interleaving distance is a widely accepted metric for comparing merge trees, with applications in visualization and scientific computing. While a greedy algorithm exists for finding the interleaving distance between labeled merge trees with overlapping labels, computing the interleaving distance between unlabeled trees or labeled trees with disjoint labels remains a significant challenge. In this work, we introduce a novel h…

Cosmographic Footprints of Dynamical Dark Energy
We introduce a novel cosmographic framework to trace the late-time kinematics of the Universe without assuming any underlying dynamics. The method relies on generalized Padé-$(2,1)$ expansions around arbitrary pivot redshifts, which, compared to state-of-the-art calculations, reduce truncation errors by up to two orders of magnitude at high redshift and yield more precise constraints by defining cosmographic parameters exactly where the data lie. This avoids extrapolations, mitigates degenerac…

Unified dark fluid with null sound speed as an alternative to phantom dark energy
Recent BAO measurements from DESI, when combined with CMB and supernovae data, suggest evolving dark energy and in particular point to a possible phantom regime, with an equation of state parameter $w<-1$. We explore an alternative phenomenological way to model dark matter and dark energy based on a unified dark fluid (UDF). By construction, our model reproduces the same background expansion history as DESI's best-fit using the CPL parametrization, but assumes a vanishing rest-frame sound spe…

This serves as a natural extension of the single-component, non-interacting Fuzzy Dark Matter (FDM) paradigm.

We find that the transfer function, and hence imprint on the CMB and Large-Scale Structure (LSS), is characterized by a single characteristic scale of the inte…

Complete Sampling of the $uv$ Plane with Realistic Radio Arrays: Introducing the RULES Algorithm, with Application to 21 cm Foreground Wedge Removal
We introduce the Radio-array $uv$ Layout Engineering Strategy (RULES), an algorithm for designing radio arrays that achieve complete coverage of the $uv$ plane, defined as, at minimum, regular sampling at half the observing wavelength ($λ$) along the $u$ and $v$ axes within a specified range of baseline lengths. Using RULES, we generate $uv$-complete layouts that cover the range $10λ\leq|(u,v)|\leq 100λ$ with fewer than 1000 antennas of diameter $5λ$, comparable to current and pla…
