The reason ESP, for example, is not considered a viable topic in contemporary
psychology is simply that its investigation has not proven fruitful...After
more than 70 years of study, there still does not exist one example of an ESP
phenomenon that is replicable under controlled conditions. This simple but
basic scientific criterion has not been met despite dozens of studies conducted
over many decades...It is for this reason alone that the topic is now of little

Solving engineering eigenvalue problems with neural networks using the Rayleigh quotient
From characterizing the speed of a thermal system's response to computing natural modes of vibration, eigenvalue analysis is ubiquitous in engineering. In spite of this, eigenvalue problems have received relatively little treatment compared to standard forward and inverse problems in the physics-informed machine learning literature. In particular, neural network discretizations of solutions to eigenvalue problems have seen only a handful of studies. Owing to their nonlinearity, neural network d…

The Robin heat kernel and its expansion via Robin eigenfunctions
We prove the existence and uniqueness of the Robin heat kernel on compact Riemannian manifolds with smooth boundary for Robin parameter $\a\in \R$, expressed as a spectral expansion in terms of Robin eigenvalues and eigenfunctions. For $\a>0$, the proof relies on trace Sobolev inequalities and eigenfunction estimates, while the $\a<0$ case requires new techniques to deal with $L^\infty$ estimates of Robin eigenfunctions. Our results unify the classical Dirichlet and Neumann cases while extendin…

Yay, I finally figured out how to build HTML documentation of my custom :nixos: #NixOS options. 🥳
Some thoughts:
- It still contains *all* normal NixOS options (it's a 13MB HTML file...)
- I don't see a way to filter for only my custom options - be it just by regex for example
- It's the documentation of *possible* options, doesn't include the actually chosen val…

An improved bound for strongly regular graphs with smallest eigenvalue $-m$
In 1979, Neumaier gave a bound on $λ$ in terms of $m$ and $μ$, where $-m$ is the smallest eigenvalue of a primitive strongly regular graph, unless the graph in question belongs to one of the two infinite families of strongly regular graphs. We improve this result. We also indicate how our methods can be used to give an alternate derivation of Bruck's Completion Theorem for orthogonal arrays.

Aber ich kann nicht. WAH.

Changing the ranking in eigenvector centrality of a weighted graph by small perturbations
In this article, we consider eigenvector centrality for the nodes of a graph and study the robustness (and stability) of this popular centrality measure. For a given weighted graph ${\mathcal G}$ (both directed and undirected), we consider the associated weighted adjacency matrix $A$, which by definition is a non-negative matrix. The eigenvector centralities of the nodes of ${\mathcal G}$ are the entries of the Perron eigenvector of $A$, which is the (positive) eigenvector associated with the e…
