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

Mercury in source rocks on the Norwegian Continental Shelf; link to maturity, depositional environment and age

The source of mercury (Hg) in petroleum is debated in the literature and could stem from; Hg rich black shales producing petroleum, coals, proximity to deep faults acting as migration routes from deep Hg sources, and proximity to large igneous provinces. In an attempt to cast light on the source of Hg in oils on the Norwegian Shelf 268 mainly organic rich core samples from wells in the North Sea,

The mode

Electrochemical molecularly imprinted polymer sensors in viral diagnostics : Innovations, challenges and case studies

Molecularly imprinted polymers (MIPs) are synthetic equivalent of antibodies and have been widely used in electrochemical sensing as recognition elements. They offer advantages over traditional recognition elements such as antibodies, nucleic acids and aptamers due to their simple synthesis, lower production costs, greater chemical and physical stability, and robust performance in diverse environm

The associations of the psychosocial safety climate with human service workers’ job demands, resources, and work-and health-related outcomes : A scoping review

Objectives: Human service workers are at a greater risk for negative work and health-related outcomes due to the highly demanding nature of their work which involves unique stressors such as emotion work and routine interactions with clients. This scoping review synthesizes the current state of literature reporting on the associations of psychosocial safety climate (PSC) with human service workers

Precessional variation of monsoon-controlled silicate weathering caused steady atmospheric carbon dioxide consumption during glacial periods

Silicate weathering regulates climate as a critical carbon sink, yet understanding its role in the carbon cycle is challenging because of limited knowledge about the impact of temperature and rainfall on weathering during glacial-interglacial cycles. Here we investigated the orbital scale of silicate weathering variations and their role in atmospheric carbon dioxide sequestration using reconstruct

Leveraging multi-source satellite imagery for improving daily reservoir water storage and inflow estimation in a catchment hydrological model

Accurate reservoir dynamics, particularly water storage and inflow, are crucial for release decisions and operation rule assessments. However, the lack of sufficient monitoring data has hindered the accurate representation of reservoir behavior in hydrological models. While the increasing availability of satellite imagery provides unprecedented opportunities for dynamic reservoir monitoring, its p

Solar chimney combined with active cooling systems for enhanced indoor comfort and energy efficiency under extreme climates : A data-driven optimization approach

Climate change and its associated extreme events challenge the effectiveness of passive building design strategies. Hybrid passive-active systems emerge as a promising solution; however, their resilience in extreme climate conditions is less studied. This study addresses this gap by investigating the integration of solar chimneys (SC) with variable refrigerant flow (VRF) systems to improve thermal

Association between urinary heavy metal concentrations, thyroid hormones, and birth outcomes among pregnant women in Isfahan City

Heavy metals are toxic elements that can have significant adverse effects on human health, particularly during vulnerable periods such as pregnancy. The presence of heavy metals in the environment can lead to increased exposure in pregnant women, which may adversely affect both maternal and neonatal health. This study investigates the relationship between heavy metal concentrations, thyroid hormon

Deposition and 14C-based source apportionment of black carbon in a small lake in southern Sweden since 1450 CE

Black carbon (BC) is produced by incomplete combustion of biomass and fossil fuels and is released as aerosols to the atmosphere with effects on the climate, environment, and human health. Current BC emissions are well monitored in many parts of the world. However, the geographical coverage is limited, and historical records of BC accumulation are still scarce. Here we present a quantification of

Association of height, BMI, and smoking status with prostate cancer risk before and after the introduction of PSA testing in Sweden

Prostate cancer (PCa) incidence has steadily increased in Sweden, more steeply in the mid-1990s caused by increased opportunistic prostate-specific antigen (PSA) testing. Tallness, normal weight, and non-smoking are associated with more PSA testing, which increases detection of low-risk and localised PCa. We investigated time trends of height, body mass index (BMI), and smoking with PCa risk in 17

Topological Weyl altermagnetism in CrSb

Altermagnets constitute a novel, third fundamental class of collinear magnetic ordered materials, alongside with ferro- and antiferromagnets. They share with conventional antiferromagnets the feature of a vanishing net magnetization. At the same time they show a spin-splitting of electronic bands, just as in ferromagnets, caused by the atomic exchange interaction. On the other hand, topology has r
