Actuation Strategies for Underwater Jet‐Propelled Soft Robots

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Authoring Terrestrial Planets with Diffusion Models

open access: yesComputer Graphics Forum, EarlyView.
Abstract To support the design and subsequent generation of terrestrial planets for use in the creative media, we propose a solution that employs a generative model trained on satellite data from planetary bodies with a defined solid surface, such as the Earth and Mars.

Kirkwood–Dirac quasiprobabilities for measurements related to mutually unbiased equiangular tight frames

open access: yesAPL Quantum
Protocols of quantum information science often realize in terms of specially selected states. In particular, such states are used to perform measurements at the final stage of a protocol.

Complementary Capacities and Shared Challenges: Lessons From a Brazil‐Australia Water Management Consortium

open access: yesWorld Water Policy, Volume 12, Issue 2, May 2026.
ABSTRACT Transnational collaboration is critical for water‐security innovation, yet actor configurations and thematic priorities remain poorly characterized. We surveyed 92 Australian and Brazilian researchers from the Tropical Water Research Alliance (TWRA), analyzing 11 sets of binary variables on collaboration modes, stakeholders, implementation ...

Construction of k-angle tight frames

open access: yes, 2016
Frames have become standard tools in signal processing due to their robustness to transmission errors and their resilience to noise. Equiangular tight frames (ETFs) are particularly useful and have been shown to be optimal for transmission under a ...

Score‐Based Generative Emulation of Impact‐Relevant Earth System Model Outputs

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Policy targets evolve faster than the Couple Model Intercomparison Project cycles, complicating adaptation and mitigation planning that must often contend with outdated projections. Climate model output emulators address this gap by offering inexpensive surrogates that can rapidly explore alternative futures while staying close to Earth system

Equiangular tight frames with centroidal symmetry

open access: yesApplied and Computational Harmonic Analysis, 2018
An equiangular tight frame (ETF) is a set of unit vectors whose coherence achieves the Welch bound, and so is as incoherent as possible. Though they arise in many applications, only a few methods for constructing them are known. Motivated by the connection between real ETFs and graph theory, we introduce the notion of ETFs that are symmetric about ...
