Effective Policy Learning for Multi-Agent Online Coordination Beyond Submodular Objectives
In this paper, we present two effective policy learning algorithms for multi-agent online coordination(MA-OC) problem. The first one, \texttt{MA-SPL}, not only can achieve the optimal $(1-\frac{c}{e})$-approximation guarantee for the MA-OC problem with submodular objectives but also can handle the unexplored $α$-weakly DR-submodular and $(γ,β)$-weakly submodular scenarios, where $c$ is the curvature of the investigated submodular functions, $α$ denotes the diminishing-return(DR) ratio and t…

Just spent the last two days on a Remote Area First Aid course, run by JP of the Overland Guide Association. Really enjoyed it and definitely learned lots.

Thermodynamics of BTZ Black Holes in Bumblebee Gravity with Barrow Entropy with Cavity-Modification
We investigate the thermodynamics of $(2+1)$ dimensional BTZ black holes in the Einstein bumblebee gravity theory with spontaneous breaking of Lorentz symmetry caused by a nonzero vacuum expectation value of the vector field. We analyse corrections to black hole thermodynamics, including the non extensive Barrow entropy, parametrising quantum gravitational corrections to the Bekenstein Hawking area law. We introduce the York cavity formalism by placing the black hole in a finite isothermal cavi…

Bacterial Gene Regulatory Neural Network as a Biocomputing Library of Mathematical Solvers
Current biocomputing approaches predominantly rely on engineered circuits with fixed logic, offering limited stability and reliability under diverse environmental conditions. Here, we use the GRNN framework introduced in our previous work to transform bacterial gene expression dynamics into a biocomputing library of mathematical solvers. We introduce a sub-GRNN search algorithm that identifies functional subnetworks tailored to specific mathematical calculation and classification tasks by evalu…

Outcomes-over-outputs is one thing — but even outcomes aren't always impactful.
Investing in any outcome carries opportunity cost. Any effort you expend means not spending that effort elsewhere.
And when there's a bottleneck in the system, effort upstream of the bottleneck has diminishing returns. Typically, that bottleneck is your process.
Since the process is made up of people, technical solutions won't help.

All your problems are people problems (Don't Just Do Things, Part 2)
If you want to do strategy, you must be willing to do process transformation first.

Abstract: We develop here a stochastic framework for modeling and segmenting transient spindle- like oscillatory bursts in electroencephalogram (EEG) signals. At the modeling level, individ- ual spindles are represented as path realizations of a two-dimensional Ornstein{Uhlenbeck (OU) process with a stable focus, providing a low-dimensional stochastic dynamical sys- tem whose trajectories reproduce key morphological features of spindles, including their characteristic rise{decay amplitude envelopes. On the signal processing side, we propose a segmentation procedure based on Empirical Mode Decomposition (EMD) combined with the detection of a central extremum, which isolates single spindle events and yields a collection of oscillatory atoms. This construction enables a systematic statistical analysis of spindle features: we derive empirical laws for the distributions of amplitudes, inter-spindle intervals, and rise/decay durations, and show that these exhibit exponential tails consistent with the underlying OU dynamics. We further extend the model to a pair of weakly coupled OU processes with distinct natural frequencies, generating a stochastic mixture of slow, fast, and mixed spindles in random temporal order. The resulting framework provides a data- driven framework for the analysis of transient oscillations in EEG and, more generally, in nonstationary time series.
