Learning to Equalize for Single-Carrier Underwater Acoustic Communications
Journal of Marine Science and EngineeringLearning-based equalizers for multicarrier communication systems have been widely studied over underwater acoustic (UWA) channels. In this article, a learning-based equalizer is utilized for single-carrier (SC) underwater acoustic communications.

Cognitive Spectrum Access for Underwater Acoustic Communications
, 2008 While very successful in traditional radio communications, the usage of TDMA and CSMA schemes for underwater acoustic communications is severely limited in efficiency and scalability, primarily due to the very large propagation delays.

Aggregate, Volume 7, Issue 6, June 2026.The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Recent advances in organic broad‐spectrum photodetection materials and devices
InfoMat, Volume 8, Issue 6, June 2026.This review systematically outlines the evolution of organic photodetectors from fullerene‐based to advanced non‐fullerene acceptors, highlighting how molecular engineering (e.g., D–A, quinoidal, and A‐D‐A′‐D‐A architectures) extends spectral response into the short‐wave infrared region.

Growing trees on farms: Navigating the goals and values of farmers
People and Nature, Volume 8, Issue 6, Page 1615-1628, June 2026.Abstract Agricultural landscapes represent critical contexts for advancing policy objectives related to tree cover expansion. This paper explores how farmers' values influence their willingness or ability to grow trees on farms. Research is based on 49 interviews and two focus groups with farmers in England and draws on two social science research ...

People and Nature, Volume 8, Issue 6, Page 1957-1973, June 2026.Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

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.
