ENSO or the Atlantic: Which Actually Governs the Hydrological Vulnerability of the Caatinga?

open access: yesInternational Journal of Climatology, EarlyView.
This study challenges the traditional ENSO‐centric paradigm of rainfall variability in the Caatinga by demonstrating that the Tropical Atlantic exerts a statistically dominant influence on regional hydrological vulnerability. Using a seasonal ARX/HAC model and CHIRPS data, we establish a new hierarchy of climatic drivers across six rainfall districts ...

Biochar and Hydrochar as Soil‐Based Carbon Sequestration Technologies: Implications for Greenhouse Gas Mitigation

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Biochar and hydrochar have emerged as promising carbon‐based amendments for enhancing soil carbon sequestration and mitigating greenhouse gas emissions. This review synthesizes and critically compares current knowledge on the production technologies, physicochemical properties, stabilization mechanisms, carbon persistence, and life‐cycle ...

White and whole wheat flour breads: composition and simultaneous exposure to group B trichothecenes

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The study aimed to determine the profile of group B trichothecenes (TCTBs), to estimate the daily exposure to them and to evaluate the relationship with the composition of different types of sliced wheat bread. A method for simultaneous determination of the TCTBs (deoxynivalenol (DON), 3‐acetyl‐deoxynivalenol, 15‐acetyl ...

Uncertainty, Sensitivity, and Efficiency Analysis of a Hybrid Piezoelectric–Electromagnetic Energy Harvester

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Digitalization and emerging technologies are increasing the demand for wireless sensing and the Internet of Things (IoT), which provide opportunities for autonomous sources of electricity in the form of energy harvesting systems. This paper focuses on the challenges in hybrid piezoelectric‐electromagnetic kinetic energy harvesting systems that

Bulbophyllum weddellii (Orchidaceae) demonstrates foliar water uptake plasticity along Brazilian campos rupestres

open access: yesNordic Journal of Botany, EarlyView.
Phenotypic plasticity can facilitate species survival in a variety of conditions that are not possible with a fixed phenotype. Foliar water uptake (FWU), defined as the absorption of water through leaf surfaces, is an important mechanism contributing to plant water balance and drought tolerance in many species.

Treasures of the Serra da Jiboia (Bahia, Brazil): a new species of Racinaea and an overview of the local Bromeliaceae flora

open access: yesNordic Journal of Botany, EarlyView.
Serra da Jiboia, located in the south‐central region of Bahia, represents an important ecotone between the Atlantic Forest and the Caatinga and harbors high floristic diversity and numerous endemic species. The Bromeliaceae family, well represented in the region, stands out for its ecological importance and adaptability to various microenvironments ...

An Adaptive Multiple Shooting Strategy for Optimal Control

open access: yesOptimal Control Applications and Methods, EarlyView.
We study how multiple shooting affects the convergence of Newton‐type methods for optimal control, comparing several shooting strategies across 40 benchmark problems. The study covers interior‐point and sequential quadratic programming methods with both Quasi‐Newton approximations and exact Hessians.

Extension of Isoconversional Analysis to Diffusion‐Controlled Epoxy Cure Kinetics: Comparison With Model‐Fitting Approaches

open access: yesPolymer Engineering &Science, EarlyView.
Extending isoconversional analysis of DSC data to diffusion‐controlled regimes captures the rise in apparent activation energy upon vitrification and yields TTT diagrams of RTM6 epoxy resin that remain accurate when diffusion, rather than chemistry, governs the cure rate.
