Analytical and numerical study of the ground-track resonances of Dawn orbiting Vesta [PDF]

open access: yes, 2011
The aim of Dawn mission is the acquisition of data from orbits around two bodies, (4)Vesta and (1)Ceres, the two most massive asteroids. Due to the low thrust propulsion, Dawn will slowly cross and transit through ground-track resonances, where the ...

The Effect of Individual Difference on Perceptions of Job-related Stress among National College and University Librarians in Taiwan [PDF]

open access: yesJournal of Library and Information Studies, 2004
Defined as an environment force in the workplace, either real or imagined, job-related stress interacts with an individual's perception. Individuals' perceptions of job-related stress vary widely.

Quantum groups, Yang-Baxter maps and quasi-determinants

open access: yes, 2017
For any quasi-triangular Hopf algebra, there exists the universal R-matrix, which satisfies the Yang-Baxter equation. It is known that the adjoint action of the universal R-matrix on the elements of the tensor square of the algebra constitutes a quantum ...

Hamiltonian Determination with Restricted Access in Transverse Field Ising Chain

open access: yes, 2010
We propose a method to evaluate parameters in the Hamiltonian of the Ising chain under site-dependent transverse fields, with a proviso that we can control and measure one of the edge spins only.

Drought-resistant wheat variety shapes soil fungal communities, enhancing nitrogen use efficiency under drought stress

open access: yesAgricultural Water Management
Enhancing nitrogen use efficiency (NUE) and crop water productivity (WPc) in drought-resistant wheat under limited irrigation is essential to mitigate water scarcity in the North China Plain (NCP).

Site-selective quantum correlations revealed by magnetic anisotropy in the tetramer system SeCuO3 [PDF]

open access: yes, 2012
We present the investigation of a monoclinic compound SeCuO3 using x-ray powder diffraction, magnetization, torque and electron-spin-resonance (ESR). Structurally based analysis suggests that SeCuO3 can be considered as a 3D network of tetramers.

Evaluating the accuracy of the EcoservR toolkit for fine‐resolution habitat mapping

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
Accurate habitat maps are essential for monitoring ecological change and supporting nature recovery planning. We evaluate the EcoservR rule‐based habitat mapping toolkit using field survey data from Merseyside and the North York Moors, validating classifications across the Joint Nature Conservation Committee (JNCC) Phase 1 hierarchy.
