Exploiting Anonymity in Approximate Linear Programming: Scaling to Large Multiagent MDPs (Extended Version) [PDF]
Many exact and approximate solution methods for Markov Decision Processes (MDPs) attempt to exploit structure in the problem and are based on factorization of the value function.

We present a complete analysis of multipartite entanglement of three-mode Gaussian states of continuous variable systems. We derive standard forms which characterize the covariance matrix of pure and mixed three-mode Gaussian states up to local unitary ...

Mechanisms of parasite‐mediated disruption of brain vessels
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

This study proposes a fault-tolerant matrix-converter-controlled IPMSM-drive system, in which a predictive speed-loop controller and a predictive current-loop controller are implemented to improve its dynamic responses, including transient responses and ...

Tensor models and 3-ary algebras
Tensor models are the generalization of matrix models, and are studied as models of quantum gravity in general dimensions. In this paper, I discuss the algebraic structure in the fuzzy space interpretation of the tensor models which have a tensor with ...

Time after time – circadian clocks through the lens of oscillator theory
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Sliding observer-based demagnetisation fault-tolerant control in permanent magnet synchronous motors
This study proposes a fault-tolerant control method for permanent magnet synchronous motors (PMSMs) based on the active flux linkage concept, which addresses permanent magnet (PM) demagnetisation faults in PMSMs. First, a mathematical model for a PMSM is

The newfound relationship between extrachromosomal DNAs and excised signal circles
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Hysteretic non-linearity observer design and robust control for piezoelectric actuators
The problem of tracking control for piezoelectric actuator (PEA) is investigated in this article. In consideration of that, the control precision of PEA is being restricted due to the hysteretic effect.
