Simulating sparse SYK model with a randomized algorithm on a trapped-ion quantum computer
The Sachdev-Ye-Kitaev (SYK) model describes a strongly correlated quantum system that shows a strong signature of quantum chaos. Due to its chaotic nature, the simulation of real-time dynamics becomes quickly intractable by means of classical numerics, and thus, quantum simulation is deemed to be an attractive alternative. Nevertheless, quantum simulations of the SYK model on noisy quantum processors are severely limited by the complexity of its Hamiltonian. In this work, we simulate the real-t…

Stability of Stochastically Driven Couette Flow in 2D with Navier Boundary Conditions at high Reynolds number via Averaging Principle
We characterize the behavior of stochastic Navier-Stokes on $\mathbb{T} \times [-1,1]$ with Navier boundary conditions at high Reynolds number when initialized near Couette flow subject to small additive stochastic forcing. We take additive noise of strength $ν^{1/2+} ΦdV_t + ν^{2/3+α} ΨdW_t$, where $ΦdV_t$ has spatial correlation in $H_0^3$ and acts only on $x$-independent modes of the vorticity, while $ΨdW_t$ has spatial correlation in a lower order, anisotropic, Sobolev space $\mathca…

UAVs Meet Agentic AI: A Multidomain Survey of Autonomous Aerial Intelligence and Agentic UAVs
Agentic UAVs represent a new frontier in autonomous aerial intelligence, integrating perception, decision-making, memory, and collaborative planning to operate adaptively in complex, real-world environments. Driven by recent advances in Agentic AI, these systems surpass traditional UAVs by exhibiting goal-driven behavior, contextual reasoning, and interactive autonomy. We provide a comprehensive foundation for understanding the architectural components and enabling technologies that distinguish…

Regierung in Paris erfragt bei Renault Bereitschaft zu Drohnen-Bau für Ukraine
Der französische Autohersteller Renault steht im Kontakt mit der Regierung in Paris über den möglichen Bau von Drohnen in der Ukraine. Renault teilte mit, das Verteidigungsministerium habe nachgefragt, ob der Autobauer bei der Herstellung von Drohnen helfen könne. "Es hat Gespräche gegeben, aber es wurde noch keine Entscheidung getroffen, da wir we…

Square Functions and Variational Estimates for Ritt Operators on $L^1$
Let $T$ be a bounded operator. We say $T$ is a Ritt operator if $\sup_n n\lVert T^n-T^{n+1}\rVert<\infty$. It is know that when $T$ is a positive contraction and a Ritt operator in $L^p$, $1

Structured Variational $D$-Decomposition for Accurate and Stable Low-Rank Approximation
We introduce the $D$-decomposition, a non-orthogonal matrix factorization of the form $A \approx P D Q$, where $P \in \mathbb{R}^{n \times k}$, $D \in \mathbb{R}^{k \times k}$, and $Q \in \mathbb{R}^{k \times n}$. The decomposition is defined variationally by minimizing a regularized Frobenius loss, allowing control over rank, sparsity, and conditioning. Unlike algebraic factorizations such as LU or SVD, it is computed by alternating minimization. We establish existence and perturbation stabili…

Science at Risk: The Urgent Need for Institutional Support of Long-Term Ecological and Evolutionary Research in an Era of Data Manipulation and Disinformation
Planet Earth and the biodiversity it supports are in crisis. Human impact on terrestrial, marine and freshwater ecosystems and the hundreds of thousands of organisms that inhabit them is global. To what extent can we push ecosystems before they collapse? Will species adapt to these changes and at what rate? What are the consequences, for the environment and humankind? These are some of the most pressing issues to date. Clear answers can only be addressed through long-term research programs that…

Three-dimensional and clap-and-fling effects on a pair of flapping wings used for thrust generation
This research investigates the three-dimensional effects of flow around a pair of flapping wings undergoing clap-and-fling interactions through harmonic in-plane motions combining pitching, heaving, and deviation. Both wings mirror each other in their movements. Baseline parameters were selected based on efficient configurations from a previous two-dimensional study. Simulations at a Reynolds number of 800 were conducted on wings in a thrust configuration utilizing the clap-and-fling mechanism.…
