Soft Colloidal Robots: Magnetically Guided Liquid Crystal Torons for Targeted Micro‐Cargo Delivery

Small, Volume 22, Issue 37, 2 July 2026.
Torons, topological quasiparticles in liquid crystals, can be propelled using electric fields and precisely steered with magnetic alignment, enabling programmable motion without fluid flow. In microfluidic channels, they transport colloidal cargo and exhibit novel dynamic behavior. Their uniformity, softness, and reconfigurability make torons ideal for

Emergent Chaos‐Like Dynamics of Spin–Orbit‐Torque‐Driven Magnetic Transitions

Small, Volume 22, Issue 37, 2 July 2026.
By combining anisotropy‐engineered nanometer‐scale nucleation sites with time‐resolved x‐ray holography and micromagnetic modeling, magnetization dynamics are directly imaged, revealing chaos‐like fluctuations and skyrmion shedding and highlighting the intrinsic complexity of spin‐orbit torque driven systems.

Higher‐Order Interactions Can Promote Coexistence by Rewiring Intransitivities Into Competitive Networks

Ecology Letters, Volume 29, Issue 7, July 2026.
We integrate natural history and theory to show how higher‐order interactions (HOIs) can restructure competitive networks and influence coexistence in a tropical ant community. The HOI from a parasitoid of the dominant ant species forces the community to move between two dominance regimes, and the interregnum between regimes has multiple interacting ...

Affine hypersurfaces and superintegrable systems

Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.
Abstract It was recently shown that under mild assumptions, second‐order conformally superintegrable systems can be encoded in a (0,3)‐tensor, called structure tensor. For abundant systems, this approach led to algebraic integrability conditions that essentially allow one to restore a system from the knowledge of its structure tensor in a point on the ...

A Spreading‐Rate Dependence for Periodic Signals Embedded in Otherwise Aperiodic Abyssal Hills

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract I present evidence, through an empirical pre‐whitening analysis, that periodic signals are embedded in otherwise aperiodic abyssal hills across paleo‐spreading rates ranging from 1 to 9 cm/yr (half rate). Data are comprised of archival trackline and multibeam bathymetry profiles in north and south Atlantic Oceans, Pacific‐Antarctic Ridge ...

Dynamics of resonant soliton, novel hybrid interaction, complex N-soliton and the abundant wave solutions to the (2+1)-dimensional Boussinesq equation

Alexandria Engineering Journal
The presented work concerns with some novel solutions of the (2+1)-dimensional Boussinesq equation (BE), which acts as an important model for shallow water wave.

Atmospheric Tides Imprint a Wavenumber‐4 Structure in Topside Ionospheric ELF Wave Intensity

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Atmospheric tides produce a well known pronounced longitudinal wavenumber‐4 (WN‐4) structure in the ionosphere, but their influence on electromagnetic‐wave propagation through the ionosphere remains poorly constrained. Here we use DEMETER satellite measurements to show that the extremely low frequency (ELF) electric field in the low‐latitude ...

Global Observational Comparison of Large‐Scale Traveling Atmospheric and Ionospheric Disturbances During the May 2024 Geomagnetic Storm

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract During the geomagnetic storm on 10 May 2024, neutral density measurements from 14 Tianmu, Swarm, and GRACE‐FO satellites at ∼510 km altitude, combined with total electron content (TEC) observations, enabled the first global observational comparison of large‐scale traveling atmospheric and ionospheric disturbances (LSTADs/TIDs) via snapshots ...

N-Soliton Solutions of the Nonisospectral Generalized Sawada-Kotera Equation

Advances in Mathematical Physics, 2014
The soliton interaction is investigated based on solving the nonisospectral generalized Sawada-Kotera (GSK) equation. By using Hirota method, the analytic one-, two-, three-, and N-soliton solutions of this model are obtained.

Global Occurrence of Solitary Waves in the Martian Magnetosphere

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This letter presents a global occurrence of bipolar solitary waves (SWs) in the Martian magnetosphere. We utilized medium‐frequency electric field measurements from October 2014 to December 2023 from the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.
