Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

PLANTS, PEOPLE, PLANET, EarlyView.
Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

Near-ultrastrong nonlinear light-matter coupling in superconducting circuits

Nature Communications
Light-matter interaction between an atom and an electromagnetic resonator is ubiquitous in quantum technologies. Although linear light-matter coupling $$g{\hat{\sigma }}_{x}(\hat{a}+{\hat{a}}^{{{\dagger}} })$$ g σ ̂ x ( a ̂ + a ̂ † ) can reach the ...

Impact of small‐scale gravity waves on tracer transport

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We extend a gravity wave (GW) parametrization to calculate the tracer transport due to the GW–Stokes drift and next‐order effects, where the approach is validated by comparing coarse‐resolution simulations with parametrized GWs to high‐resolution, wave‐resolving reference simulations.

On the Role of the Normalization Factors $kappa_n$ and of the Pseudo-Metric ${cal P} neq {cal P}^dag$ in Crypto-Hermitian Quantum Models

Symmetry, Integrability and Geometry: Methods and Applications, 2008
Among ${cal P}$-pseudo-Hermitian Hamiltonians $H ={cal P}^{-1} H^dagger {cal P}$ with real spectra, the ''weaklypseudo-Hermitian" ones (i.e., those employing non-self-adjoint ${cal P} neq {cal P}^dagger$) form a remarkable subfamily. Welist some reasons

A pilot variational coupled reanalysis based on the CESAM climate model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Variational data assimilation of in‐situ and satellite ocean data and reanalysis atmospheric data into an intermediate complexity Earth system model is possible by adjusting the surface fluxes and internal model parameters. This pilot application requires nearly complete information on the atmospheric state for synchronization.

Biomimetic Multifinger Tactile Sensing and Contact‐Regulated Palpation for Autonomous Breast Tumor Localization

Journal of Field Robotics, EarlyView.
ABSTRACT Early detection of breast abnormalities remains challenging: manual palpation is subjective and operator‐dependent, while imaging modalities may miss small or subtle stiffness anomalies. This paper presents a biomimetic multifinger robotic palpation approach intended to support early breast‐cancer screening and follow‐up assessment as a proof ...

Quantum-state engineering in cavity magnomechanics formed by two-dimensional magnetic materials

New Journal of Physics
Cavity magnomechanics has become an ideal platform to explore macroscopic quantum effects. Bringing together magnons, phonons, and photons in a system, it opens many opportunities for quantum technologies.

Microstructure Evolution in Directionally Solidified Fe–C–Mn–(Si) Peritectic Steels

steel research international, EarlyView.
This study investigates how growth velocity and silicon additions affect dendritic morphology, primary arm spacing, and mushy‐zone evolution in directionally solidified quaternary peritectic steels. Silicon substantially broadens the freezing range and lengthens the mushy zone, increasing susceptibility to interdendritic cracking.

The First World War at Sea: Death, Commemoration and Cultural Remembrance

History, EarlyView.
Abstract Despite the ever‐increasing body of work devoted to war memorials, national days of remembrance and the commemoration of the First World War in Britain, academic focus remains firmly on the commemoration of the First World War on land. Yet, while the number of people who died at sea paled in comparison to their counterparts on the battlefield ...

Superconformal blocks for stress-tensor and chiral operators for 4D $${\mathcal {N}}=2$$ N = 2 superconformal field theories

European Physical Journal C: Particles and Fields
We have computed the superconformal partial wave for the mixed correlators involving J, $$\phi $$ ϕ , and $$\phi ^\dagger $$ ϕ † , where J is the superconformal primary of 4D $${{\mathcal {N}}} = 2$$ N = 2 stress-tensor multiplet, $$\phi $$ ϕ , and ...
