Is It Easier to Count Communities Than Find Them?
Random Structures &Algorithms, Volume 68, Issue 4, July 2026.ABSTRACT Random graph models with community structure have been studied extensively in the literature. For both the problems of detecting and recovering community structure, an interesting landscape of statistical and computational phase transitions has emerged. A natural unanswered question is: Might it be possible to infer properties of the community

Maximum Induced Trees and Forests of Bounded Degree in Random Graphs
Random Structures &Algorithms, Volume 68, Issue 4, July 2026.ABSTRACT The asymptotic behavior of the maximum sizes of induced trees and forests has been studied extensively in the last few decades, though the overall picture is far from being complete. In this paper, we close several significant gaps: (1) We prove 2‐point concentration of the maximum sizes of an induced forest and an induced tree with maximum ...

Sharper Bounds in Lattice-Based Cryptography using the Rényi Divergence [PDF]
, 2017 The Rényi divergence is a measure of divergence between distributions. It has recently found several applications in lattice-based cryptography. The contribution of this paper is twofold.

Divergence de Rényi comme mesure de contraste pour la détection d'objets dans des images bruitées
, 2015 National audienceA binary detection task on the presence or absence of an object over a background in noisy images is studied based on a contrast metric taken as the Rényi divergence.

Mid‐Domain Effect and Wooded Habitat Shape Mediterranean Reptile Communities
Biological Diversity, Volume 3, Issue 2, Page 65-82, June 2026.Analyzing a large number of reptiles observed across protected areas in Central Italy, we tested whether the mid‐domain effect explains hump‐shaped richness–elevation patterns. Species richness was best predicted by the combined influence of geometric constraints and woodland cover, revealing two contrasting species clusters and offering a robust ...

The α → 1 limit of the sharp quantum Rényi divergence
Fawzi and Fawzi [Quantum 5, 387 (2021)] recently defined the sharp Rényi divergence, Dα#, for α ∈ (1, ∞), as an additional quantum Rényi divergence with nice mathematical properties and applications in quantum channel discrimination and quantum ...

Governing by Ambiguity: Sociotechnical Imaginaries of Platforms in China
Policy &Internet, Volume 18, Issue 2, June 2026.ABSTRACT Besides clear policy directives, the unresolved and open‐ended elements in policy communication also create discursive politics. This article argues that ambiguity in policy communication reflects the state's exercise of power within a fractured sociocultural landscape.

Quantum Information Measures of a Dirichlet Waveguide with Neumann Window(s)
Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.ABSTRACT Engineering boundary conditions in low‐dimensional structures provides a simple yet powerful way of shaping how quantum information is stored and transported. We investigate a flat 2D Dirichlet waveguide containing one or two finite Neumann windows and compute the bound states in both position and momentum space as functions of the window ...

Rényi Divergence Variational Inference
, 2017 This paper introduces the $\textit{variational Rényi bound}$ (VR) that extends traditional variational inference to Rényi’s $\alpha$-divergences. This new family of variational methods unifies a number of existing approaches, and enables a smooth ...
