The GrassSyn dataset: Soil organic carbon stocks in Brazilian grassy ecosystems. [PDF]

open access: yesJ Environ Qual
Abstract Although ecosystem management and restoration are known to enhance carbon storage, limited knowledge of ecosystem‐specific soil organic carbon (SOC) stocks and processes hinders the development of climate‐ready, biodiversity‐focused policies. Baseline SOC stocks data for specific ecosystems is essential.

Gold‐FISH enables targeted NanoSIMS analysis of plant‐associated bacteria

open access: yesNew Phytologist, Volume 240, Issue 1, Page 439-451, October 2023., 2023
Summary Bacteria colonize plant roots and engage in reciprocal interactions with their hosts. However, the contribution of individual taxa or groups of bacteria to plant nutrition and fitness is not well characterized due to a lack of in situ evidence of bacterial activity.

Hyperinsulinemia is a probable trigger for weight gain and hyperphagia in individuals with Prader‐Willi syndrome

open access: yesObesity Science &Practice, Volume 9, Issue 4, Page 383-394, August 2023., 2023
Prader‐Willi syndrome (PWS) is the most frequently diagnosed genetic cause of early childhood obesity and individuals with PWS typically progress through 6 different postnatal nutritional phases during their lifetime. The results of our study suggest elevated insulin signaling may be a trigger for rapid weight gain early‐on in PWS.

Ornithine δ‐aminotransferase OsOAT is critical for male fertility and cold tolerance during rice plant development

open access: yesThe Plant Journal, Volume 114, Issue 6, Page 1301-1318, June 2023., 2023
SUMMARY Cold stress is a major factor limiting the production and geographical distribution of rice (Oryza sativa) varieties. However, the molecular mechanisms underlying cold tolerance remain to be elucidated. Here, we report that ornithine δ‐aminotransferase (OsOAT) contributes to cold tolerance during the vegetative and reproductive development of ...

Anthropause environmentalisms: Noticing natures with the Self‐Isolating Bird Club

open access: yesTransactions of the Institute of British Geographers, Volume 48, Issue 2, Page 232-248, June 2023., 2023
Short Abstract This paper offers a detailed empirical account of how human‐environment relations were reconfigured in the UK and Ireland during the 2020–2021 COVID‐19 lockdowns, a period which natural scientists defined as the COVID‐19 Anthropause. Bringing this scientific concept into conversation with geographical work, we consider anthropause as ...

Modulational Instability and Dynamical Growth Blockade in the Nonlinear Hatano–Nelson Model

open access: yesAdvanced Physics Research, Volume 4, Issue 5, May 2025.
The nonlinear Hatano–Nelson model under periodic boundary conditions is investigated, revealing a novel growth blockade phenomenon triggered by the modulational instability of nonlinear plane waves. This effect, characterized by the abrupt halt of norm growth, arises from self‐induced disorder, marking a departure from the convective motion observed in

A 3‐D FDTD Methodology for Modeling the Propagation of VLF Whistler Mode PLHR Waves Through the Ionosphere

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 2, February 2025.
Abstract The finite‐difference time‐domain (FDTD) method was previously applied to high‐frequency electromagnetic wave propagation through 250 km of the F region of the ionosphere. That modeling approach was limited to electromagnetic wave propagation above the critical frequency of the ionospheric plasma, and it did not include the lower ionosphere ...

A High‐Order Impedance Boundary Condition Enhanced Integral Equation Solver for Scattering From the Coated Bodies of Revolution

open access: yesElectronics Letters, Volume 61, Issue 1, January/December 2025.
A novel high‐order impedance boundary condition (HOIBC)‐enhanced integral equation solver is proposed for the analysis of electromagnetic scattering from bodies of revolution (BoR) with low‐index coatings. By leveraging BoR symmetry, the proposed BoR‐HOIBC method reduces unknowns, enhancing computational efficiency compared to traditional JMCFIE.

Physics‐Informed Neural Networks Based on Unsupervised Learning for Multidomain Electromagnetic Analysis

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
This research proposes a novel numerical analysis method to employ PINNs based on unsupervised learning to solve multidomain problems. The discretised direct boundary integral equations are utilised to solve the physical quantity in the interface, and the multidomain problem can be transformed into multiple single‐domain problems.

An improved standalone photovoltaic system with hybrid dual integral sliding mode and model predictive control for MPPT

open access: yesIET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
Fig. 1(a) depicts the advanced standalone PV structure in which a high gain multilevel boost converter works as a concussion between the PV module and the load. Abstract In this research paper, a double diode model‐based photovoltaic (PV) system with a proposed hybrid dual integral sliding mode control (DISMC) and model predictive control (MPC) based ...
