CEASA : Dominant spatial autocorrelation in dual-constraint calibration as the game-changer for hydrological modeling with high-uncertainty remotely sensed evaporation: Application to the Meichuan basin

Accurate evapotranspiration (ET) estimation is vital for hydrological modeling, yet remotely sensed ET (RS-ET) products are often limited by algorithmic uncertainties and sensor biases. To mitigate error propagation and better capture spatial patterns, this study introduces the Composite Efficiency of Absolute ET and Spatial Autocorrelation (CEASA) —a dual-constraint framework that integrates abso

Co-adsorption of p-mercaptobenzoic acid on silver nanoparticles enhances the plasmon-mediated coupling reaction of p-ethynylaniline

The enhancement of the electromagnetic field elicited by localized surface plasmon resonance (LSPR) is conducive to the generation of charge carriers, which have an important effect in driving many kinds of chemical reactions. Nonetheless, the short lifespan of charge carriers generated by plasmon (typically femtoseconds to nanoseconds) limits their effectiveness in promoting chemical reactions. H

Is the audience gender-blind? Smaller attendance in female talks highlights an imbalanced visibility in academia

Diverse perspectives are essential to the advancement of biodiversity science, yet persistent structural biases continue to shape who is seen and heard in academic spaces. Despite efforts to promote inclusivity, it remains unclear whether increased representation translates into equitable visibility and engagement from peers. Seminar talks, key arenas for idea exchange and networking, offer a wind

Boosting structural food science using X-ray and neutron techniques

Knowledge about food structures at different length scales is key for the continued development of sustainable, tasty and healthy foods. It is critical to control, model and predict the supramolecular architecture of foods along the whole value chain: from raw materials, to their changes during processing, all the way to how products form structures during consumption and digestion. Today, advance

Broad-scale overdose education and naloxone distribution– 5-year follow-up of a regional program in Skåne County, Sweden

Background: Opioid use disorder is a chronic disorder with a high risk of overdose-related morbidity and mortality where a large proportion of these can be averted by timely administration of the antidote naloxone. For naloxone to be present when and where overdoses occur, broad-scale overdose education and naloxone distribution (OEND) must be established. A regional naloxone program was implement

Probabilistic human health risk assessment from groundwater fluoride contamination in Main Ethiopia Rift

Fluoride toxicity has become a significant global public health concern, with drinking water being a major source of exposure. This study aimed to determine groundwater fluoride concentration and assess its non-carcinogenic health effects on human health. A longitudinal study design was applied to select water samples in dry and wet seasons from Adama City and Wenji Gefersa town of Ethiopia. Groun

Maternal outcomes among women with intellectual disabilities in comparison with the general population (IDcare)

BACKGROUND: Women with intellectual disabilities face significant barriers to gynecological, reproductive, antenatal, and perinatal care, which may adversely impact maternal and fetal health. Previous research indicates increased risks for gestational diabetes, pre-eclampsia, caesarean birth, preterm birth, and other complications in pregnant women with intellectual disabilities. However, studies

Unleashing phosphorus mononitride

The interstellar diatomic molecule, phosphorus mononitride (P≡N), is highly unstable under conditions typical on Earth, and its utility for constructing elusive P–N π-bonded motifs has remained uncertain. Here, we show how Na(OCP) transfers a P atom to an electrophilic osmium nitride complex to form a metal-bound P≡N ligand. Quantum chemical calculations and X-ray absorption spectroscopy unveil a

A dephasing sweet spot with enhanced dipolar coupling

Two-level systems (TLSs) are the basic units of quantum computers but face a trade-off between operation speed and coherence due to shared coupling paths. Here, we investigate a TLS given by a singlet-triplet (ST+) transition. We identify a magnetic-field configuration that maximizes dipole coupling while minimizing total dephasing, forming a compromise-free sweet spot that mitigates this fundamen

Characteristic mode analysis of acoustic scatterers

The explicit connection between the transition matrix and boundary element method integral operators is formulated. This enables the calculation of characteristic modes via eigenvalue problems involving either set of operators, leading to convenient orthogonality properties facilitating scattering analysis, solution of inverse problems, and the design of excitation fields. MATLAB implementation of

Dissolution of cellulose in alkali : A competition between ionization and hydrophobic interactions.

Dissolution is a key factor in better utilization of cellulose, the most abundant macromolecule on our planet. Several non-aqueous solvent systems, of very different nature, have been found to dissolve significant amounts of cellulose. For reasons of cost, safety and environment, however, water-based systems would have high priority. Cellulose is insoluble in water, but since well above 100 years,

Habitat loss, not fragmentation per se, drives structural changes and species turnover in plant–vertebrate pollinator networks

When natural areas are converted for human use, resulting changes in the landscape often lead to habitat loss and fragmentation, which can disrupt key ecological interactions such as pollination by animals. In this study, we investigated the independent effects of habitat loss and fragmentation on the structure and composition of plant-vertebrate pollinator interaction networks, focusing on intera
