Online Adaptation for Flying Quadrotors in Tight Formations
The task of flying in tight formations is challenging for teams of quadrotors because the complex aerodynamic wake interactions can destabilize individual team members as well as the team. Furthermore, these aerodynamic effects are highly nonlinear and fast-paced, making them difficult to model and predict. To overcome these challenges, we present L1 KNODE-DW MPC, an adaptive, mixed expert learning based control framework that allows individual quadrotors to accurately track trajectories while …

A stochastic model for the diffusion of competing opinions with trend-following, opposition, and indifference
We study a stochastic model for the diffusion of competing opinions in a population composed of three types of agents: trend-followers, opposers, and indifferent individuals. The decision dynamics are driven by reinforcement mechanisms, modulated by a latent trend process, allowing us to capture realistic features such as amplification, resistance, and randomness in opinion formation. We derive explicit formulas for the finite-time moments of the opinion count vector and establish a set of stro…

Distinguishing Filling Invariants Associated to Conjugacy in Groups
Brick and Corson introduced annular Dehn functions in 1998 to quantify the conjugacy problem for finitely generated groups and gave the fundamental relationships between it, the Dehn function, and the conjugator length function. We furnish the theory with diverse examples groups. In particular, we show that these three invariants are independent -- no two of the three functions determine the other.

Exact static linear response of excited states from ensemble density functional theory
Following a recent work [E. Fromager, J. Phys. Chem. A 2025, 129, 4, 1143-1155] on the ensemble density functional theory (DFT) of excited electronic energy levels, we derive in this paper the ensuing static linear response theory, thus allowing for an in-principle exact evaluation of excited-state density-density linear response functions in a completely frequency-independent setting. Once individual-state components of the inverse ensemble linear response function have been introduced, a work…

It seems like, again, just following the plain logic of the Constitution and Declaration of Independence (which, again, I do not subscribe to), that every law passed under Trump, every supreme court justice appointment by Trump, every supreme court ruling by Trump appointed justices, all the illegal firing, etc, must all, necessarily, be null and void.
And if not following from the insurrection act, or from the oath of office, then following from the Declaration of Independence itself. The logic here being that a constitution is a contract between the people and their government, which the later upholds in order to maintain its legal status. The violation of said laws by the government violates "consent of the governed" (which, again, I have issues with the concept entirely but we're just going to ignore that) and therefore nullifies the authority of that government, granting " the right of the people to alter or to abolish it."
That seems a lot like the hard reset some folks have been looking for. Given that existing flaws allowed this state to be reached, it would also be necessary for the true authority to correct those mistakes before assuming authority that derives from these principles.
Now, personally, I don't subscribe to any of this logic but it's interesting to explore, as an outsider, where the logic goes.

Eukaryotic ancestry in a finite world

Eukaryotic ancestry in a finite world
Following genetic ancestry in eukaryote populations poses several open problems due to sexual reproduction and recombination. The history of extant genetic material is usually modeled backwards in time, but tracking chromosomes at a large scale is not trivial, as successive recombination events break them into several segments. For this reason, the behavior of the distribution of genetic segments across the ancestral population is not fully understood. Moreover, as individuals transmit only hal…

Happy #AutisticPrideDay! ♾️💙
I’m proudly autistic, my brain works in its own unique way, full of different thoughts and feelings all at once. Being autistic is part of who I am, not something to fix. 🧠🧠
I’m also queer and genderfluid, and that’s just another part of my colorful identity. Some days I feel one way, some days another, and that’s okay. 🏳️‍🌈☂️
