In Colorado, students taunted their Black classmates by playing whipping sounds on their cellphones and saying they should be shot “to make us a better race.”
The only two Black students in a small district in Ohio were called the N-word by white peers starting on their first day.
They got accustomed to hearing slurs like “porch monkey” and being told to go pick cotton.
And at a school in Illinois, white students included Confederate flags in their PowerPoint presentations …

Monkey Sounds, “White Power” and the N-Word: Racial Harassment Against Black Students Ignored Under Trump
Since Trump returned to office, the Education Department’s civil rights office has not resolved a single racial harassment investigation. It sends a message that “people impacted by racial discrimination ... don’t matter,” one attorney said.

Learning the Wrong Lessons: Syntactic-Domain Spurious Correlations in Language Models
For an LLM to correctly respond to an instruction it must understand both the semantics and the domain (i.e., subject area) of a given task-instruction pair. However, syntax can also convey implicit information Recent work shows that syntactic templates--frequent sequences of Part-of-Speech (PoS) tags--are prevalent in training data and often appear in model outputs. In this work we characterize syntactic templates, domain, and semantics in task-instruction pairs. We identify cases of spurious …

Distributed Stochastic Model Predictive Control with Temporal Aggregation for the Joint Dispatch of Cascaded Hydropower and Renewables
This paper addresses the real-time energy dispatch of a hybrid system comprising cascaded hydropower plants, wind, and solar units, jointly participating in the day-ahead energy market under inflow, renewable generation, and price uncertainties. Traditional scenario-based stochastic model predictive control (MPC) faces severe computational bottlenecks due to the complexity arising from the temporal, asset, and scenario dimensions of this control problem. To address this, we propose a novel cont…

Scalar-tensor theories in the Lyra geometry: Invariance under local transformations of length units and the Jordan-Einstein frame conundrum
The Lyra geometry provides an interesting approach to develop purely geometrical scalar-tensor theories due to the natural presence of the Lyra scale function. This paper explores further the scale function source term to construct a theory on Lyra manifolds which contains proper generalizations of both Brans-Dicke gravity and the Einstein-Gauss-Bonnet scalar-tensor theory. It is shown that the symmetry group of gravitational theories on the Lyra geometry comprises not only coordinate transform…

You’ll still get your social security and Medicare.

Flights will keep going, but with unpaid and possibly limited staff.

Most parks will remain open, but will probably be under-maintained.

Smithsonian museums and the National zoo are open through at least 6 October.

Federal workers are the hardest hit, withmany being unpaid or furloughed.

Consumer protections, which have already been hit hard by cuts, are at risk of incapacity.

Tiny engine runs hotter than the sun to probe the frontiers of thermodynamics
Scientists have created the world's hottest engine running at temperatures hotter than those reached in the sun's core. The team from King's College London and collaborators believe their platform could provide an unparalleled understanding of the laws of thermodynamics on a small scale, and provide the foundation for a new, efficient way to compute how proteins fold—the subject of last year's Nobel Prize in Chemistry.

Gröbner crystal structures
We develop a theory of bicrystalline ideals, synthesizing Gröbner basis techniques and Kashiwara's crystal theory. This provides a unified algebraic, combinatorial, and computational approach that applies to ideals of interest, old and new. The theory concerns ideals in the coordinate ring of matrices, stable under the action of some Levi group, whose quotients admit standard bases equipped with a crystal structure. We construct an effective algorithm to decide if an ideal is bicrystalline. Wh…
