Does digital surveillance boost citizen compliance? Evidence from China
Political Psychology, Volume 47, Issue 4, August 2026.Abstract Authoritarian regimes increasingly deploy digital surveillance to monitor citizens, but how this affects citizen compliance remains understudied. We argue that, beyond repressing or deterring regime opponents, digital surveillance serves as an instrument of everyday governance that operates through psychological mechanisms rather than direct ...

Optimized Quantization in Distributed Graph Signal Processing [PDF]
, 2019 Distributed graph signal processing methods require that the graph nodes communicate by exchanging messages. These messages have a finite precision in a realistic network, which may necessitate to implement quantization.

A generalisation of Cameron's base size conjecture
Journal of the London Mathematical Society, Volume 114, Issue 2, August 2026.Abstract Let G⩽Sym(Ω)$G\leqslant {\rm Sym}(\Omega)$ be a finite transitive permutation group with point stabiliser H$H$. A base for G$G$ is a subset of Ω$\Omega$ whose pointwise stabiliser is trivial, and the minimal cardinality of a base is called the base size of G$G$, denoted by b(G,Ω)$b(G, \Omega)$. Equivalently, b(G,Ω)$b(G, \Omega)$ is the minimal

Statistical Graph Signal Processing: Stationarity and Spectral Estimation
, 2018 Stationarity is a cornerstone property that facilitates the analysis and processing of random signals in the time domain. Although time-varying signals are abundant in nature, in many contemporary applications the information of interest resides in more ...

Reversal of economic integration: evidence from European Union enlargement
The Scandinavian Journal of Economics, Volume 128, Issue 3, Page 660-685, July 2026.Abstract Empirical models of trade agreements implicitly assume that withdrawal from a trade agreement has an equal and opposite trade effect as accession (i.e., symmetry). With increasing opposition to international economic cooperation, it becomes urgent to test this assumption.

Graph Spectral Image Processing [PDF]
, 2018 Recent advent of graph signal processing (GSP) has spurred intensive studies of signals that live naturally on irregular data kernels described by graphs (e.g., social networks, wireless sensor networks).
