Molecular and physiological mechanisms of the cadmium response in seedlings of two Theobroma cacao L. genotypes

Abstract Aims Understanding the mechanisms of cadmium (Cd) accumulation in cacao plants is critical to mitigating health risks associated with Cd exposure through chocolate consumption. A general and genotype-specific molecular and physiological responses were characterized. Meth...

Sex Differences in Prefrontal Oxygenation and Neuromuscular Fatigue to Incremental Cycling and Cognitive Testing Lead to Similar Cognitive Performance

Purpose: Cognitive-motor dual-task performance is prevalent in many sports and appears to be impaired during high-intensity exercise, in association with central fatigue and cerebral deoxygenation. However, the extent to which these responses differ between males and females rema...

Evidence of hydrodynamic control of phytoplankton seasonality in a tropical urban estuary

Tropical urban estuaries receive year-round nutrient loads, yet their strongest phytoplankton blooms often occur in the dry season. The proximate control on this seasonality remains unresolved in wastewater-impacted tropical systems. Here we apply a transient one-dimensional Carb...

Revealing archaeological olive diversity: insights from stone geometric morphometrics, experimental charring, and varietal identification (Port-la-Nautique, France, Roman period)

The cultivated olive tree, domesticated in the Levant by the mid-5th millennium BCE, spread westward across the Mediterranean to reach southern France by 600 BCE. Although geometric morphometrics applied to archaeological olive stones has provided insights into this diffusion, mo...

Expanding Oued Beht: Final Neolithic, Bronze Age, medieval and later discoveries from excavation and survey in 2023

Abstract Oued Beht, Morocco, is emerging as a key site for understanding later prehistory in the northwestern Maghreb. Previous fieldwork by the Oued Beht Archaeological Project (OBAP) in 2022 revealed major evidence of a large and complex focus of activity across the ridge durin...

Magnetic insights into the aqueous alteration of CM chondrites

CM chondrites are the archetypal group of aqueously altered meteorites, preserving records of water-rock interactions on planetesimals. Here, we couple rock magnetic properties with modal mineralogy measured from 48 CM chondrites to explore aqueous alteration through its influenc...

A New Characterization of the Wulff Shape

We prove a new charcaterization of the Wulff shape in termes of higher order anisotropic mean curvatures. Namely, if a closed, connnected and oriented hypersurface of the Euclidean space has a constant higher order anisotropic mean curvature H F r and another one H F s almost con...

Ultrasonic time of flight technique for state of charge estimation in lithium-ion batteries

Accurate State of Charge (SoC) estimation is essential for the safe and reliable operation of lithium-ion batteries. Conventional electrical methods often require complex models and are sensitive to temperature variations and hysteresis effects. This work proposes a non-destructi...

OpenAlea.HydroRoot: A modelling framework to dissect, predict and phenotype branched root hydraulic architecture

Abstract Drought is a significant factor in agricultural losses, making it imperative to understand how root system architecture (RSA) adapts to environmental condition like water deficit. HydroRoot is a functional-structural plant model (FSPM) aimed at analyzing and simulating h...

A new transcendence measure for the values of the exponential function at algebraic arguments

Let P ∈ ℤ [ X ] ∖ { 0 } be of degree δ ≥ 1 and usual height H ≥ 1 , and let α ∈ ℚ ¯ * be of degree d ≥ 2 . Mahler proved in 1931 the following transcendence measure for e α : for any ε > 0 , there exists c > 0 such that | P ( e α ) | > c / H μ ( d , δ ) + ε where the exponent μ (...

Characterization of diseases in temporal comorbidity networks

Comorbidity networks, or disease-disease networks, represent relationships between diseases and can reveal non-random disease associations and multimorbidity structure. These patterns reflect shared pathophysiology, diagnostic pathways, and risk of adverse outcomes. Using large-s...

Holographic two-point functions of heavy operators revisited

A bstract In this paper we investigate the holographic computation of the two-point functions of $$\frac{1}{2}$$ -BPS chiral primary operators with scaling dimensions ∆ ~ N or ∆ ~ N 2 in 𝒩 = 4 SU ( N ) SYM using Type IIB supergravity. First we consider giant graviton operators, r...

Data-Driven Fault Ride-Through Operation of Distributed Grid-Forming Inverters Using Multi-Agent Reinforcement Learning

Grid-forming inverters (GFMIs) are essential for future low-inertia power systems because they establish voltage and frequency rather than simply following the grid. However, compared with synchronous machines, they have limited overload and fault current capability, so providing...

Dust radiative effects and impact on energy production over the Mediterranean Basin

Abstract. Atmospheric aerosols are among the key factors affecting the Earth’s radiation budget, playing a fundamental role in understanding climate forcing, feedback mechanisms, and their impact on future climate projections and on solar energy systems. More specifically, dust a...

Up to 16% Optical Carbon‐13 Hyperpolarization of Donor–Acceptor Molecules at 14.1 T

ABSTRACT Solid‐state nuclear magnetic resonance (NMR) is a powerful technique for structure determination with applications ranging from biology to material sciences. However, its inherent low sensitivity prevents many applications. In solids, optical hyperpolarization techniques...

Strong minimality of triangle functions

In this manuscript, we give a new proof of strong minimality of certain automorphic functions, originally results of Freitag and Scanlon (2017), Casale, Freitag and Nagloo (2020), Blázquez-Sanz, Casale, Freitag and Nagloo (2020). Our proof is shorter and conceptually different th...

Effect of oxygen ion irradiation on the visible, infrared, and Raman spectra of Phobos candidate materials: implications on the space weathering by Martian atmosphere-derived ions

Abstract The origin of Martian satellites is still under debate. Nevertheless, such information could give insights into the evolution of the Martian system and planetary formation processes. To address these questions, MMX (Martian Moons eXploration) will conduct spectroscopy (v...

Actin and myosin dynamics during epithelial remodeling in avian gastrulation

Epithelial remodeling is powered by contractile forces exerted by the actomyosin cytoskeleton. In invertebrates, pulsatile contractile flows of the medio-apical actomyosin cortex have been shown to be critical in promoting junction contraction, ultimately driving cell rearrangeme...

Core open science practices in major medical journals: development of an automatized tool based on a Large Language Model

Background Open science practices are increasingly promoted to improve the transparency and reproducibility of biomedical research, and their large-scale monitoring has been identified as a priority by initiatives such as the UNESCO Recommendation on Open Science. Existing automa...

Hydromechanical Behaviour of Intact and Recompacted Crushed Caprock for Underground CO2 Storage

Abstract This work investigates the hydromechanical behaviour of Opalinus Clay (OPA) shale as a caprock material for geological storage of CO $$_2$$ 2 . In addition to intact OPA, the hydromechanical response of crushed material is evaluated to simulate damaged zones around injec...
