Impedance Spectroscopy of Bifurcation Oscillations in S‐Type Self‐Oscillatory Devices

open access: yesAdvanced Physics Research, EarlyView.
Impedance spectroscopy (IS) reveals stability regimes and bifurcation dynamics in S‐type self‐oscillatory devices. By linking nonlinear control theory with frequency‐domain measurements, experimental signatures of oscillations, entrainment, and phase locking are directly identified.

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping

open access: yesLaser &Photonics Reviews, EarlyView.
A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

The Geoeconomic Turn on Stage: National Identity and the Interpretation of the EU's Trade Sustainability Diplomacy in Indonesia and Vietnam

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract In the context of the European Union's (EU's) geoeconomic shift, the governance of Trade and Sustainable Development (TSD) has become a central yet contested pillar of its external trade policy. Accusations of green colonialism highlight the stakes around how partner countries interpret the EU's normative agenda.

Pseudo, or Not? Neo‐Goodwinian Growth Cycles With Financial Linkages

open access: yesMetroeconomica, EarlyView.
ABSTRACT A profit‐led Goodwin mechanism generates the observed counterclockwise activity–labor share cycle. Introducing a financial linkage can reproduce this pattern even when demand is not profit‐led. This paper extends neo‐Goodwinian theory by incorporating the valuation ratio into a four‐dimensional model.

The future of soil science education at the university level to meet societal demands at the global level

open access: yesNatural Sciences Education, Volume 55, Issue 1, June 2026.
Abstract The number of soil science university programs has decreased in many countries around the world. There is an ongoing need for more effective ways to attract students to the discipline, train soil specialists, and support instructors to challenge the future format of soil science education.

Models reveal potential synergies in management actions for bull kelp forest resilience and restoration

open access: yesJournal of Applied Ecology, Volume 63, Issue 6, June 2026.
We found that urchin culling and kelp seeding interventions can be effective at rebuilding kelp forests, but require intensive effort (e.g. removing 25%–50% of urchins over multiple years), especially in the absence of predators. Our results provide recommendations for the magnitude and timing of culling and seeding that would be needed to provide ...

Isotopy and equivalence of knots in 3‐manifolds

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract Two knots K$K$ and J$J$ in S3$S^3$ are isotopic if and only if they are related by an orientation‐preserving diffeomorphism of S3$S^3$. This claim follows from the fact that any orientation‐preserving self‐diffeomorphism of S3$S^3$ is isotopic to the identity. We show that this same idea applies to any prime oriented closed 3‐manifold.

The role of edible habitat complexity in food webs

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Habitat complexity (HC) in part determines the diversity, stability, and behavior of food webs and can influence predation according to a wide variety of functional relationships. Many aquatic species provide HC and are also consumed by other species (e.g., macrophytes, corals, mussels).

MAVISp: A modular structure‐based framework for protein variant effects

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract The role of genomic variants in disease has expanded significantly with the advent of advanced sequencing techniques. The rapid increase in identified genomic variants has led to many variants being classified as Variants of Uncertain Significance or as having conflicting evidence, posing challenges for their interpretation and ...

Unraveling the Mystery of Melt Migration in Migmatites: From Channeling Instability to Pattern Formation

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Melt migration in partially molten rocks is commonly described by porous flow models controlled by the hydro‐mechanical compaction length, which effectively explains melt extraction at mid‐ocean ridges. However, this framework cannot account for the paradoxical accumulation of small melt fractions into rhythmic leucosome–melanosome bands in ...
