Leaves are valuable, but very rare, remains in archaeological contexts, as they can provide precise information on the landscape vegetation composition, the past climatic conditions and the use of plant resources in a settlement. La Draga (Spain) is an early Neolithic site partially waterlogged, which has allowed the preservation of organic material. During the excavation of the oldest level (7300

The EU and its Member States have been increasingly engaging into cooperation with third countries with the view to containing movements and preventing refugees from entering European soil. These cooperative arrangements have been critiqued for allowing EU countries to evade their responsibilities vis-a-vis refugees subjecting them to substandard treatment in transit countries. From a distributive

The emergence of the modern urban water infrastructure, albeit facilitated the waste- and stormwater management, it left some negative imprints on Iran's urban and natural environment. Among which changing the hydrology of urban watershed has great importance. Moreover, lack of resilience of the current stormwater management infrastructure is increasing the risks of urban flooding and pollution of

Nanosecond pulsed discharges (NPD) have been extensively used in plasma-assisted combustion to stimulate combustion kinetics. Experimental measurement of the energy transfer processes in non-equilibrium plasma-assisted processes is extremely difficult, as the non-equilibrium plasma discharge involves numerous different species with transient and complex three-dimensional structures across various

Understanding the flame dynamics in a nanosecond pulsed discharge (NPD) is imperative for the novel technology of plasma-assisted combustion. We conducted a systematic study on the dynamics of atmospheric NPD-assisted flames in single-pulse mode using Rayleigh scattering combined with structured illumination. The study is divided into two parts. Part I detailed the measurements and CH4/air flame r

Laser-induced fluorescence (LIF) is a widely used non-invasive method for characterizing NOx emission, mostly in combustion applications, but also in many plasma facilities. Under the carbon-free prerequisite, non-thermal plasma-assisted combustion (PAC) is a promising technology to address the low flammability issues of ammonia (NH3) flames, but nitric oxide (NO) emission remains unknown. NO quan

Background: Emerging evidence suggests that artificial intelligence (AI) can increase cancer detection in mammography screening while reducing screen-reading workload, but further understanding of the clinical impact is needed. Methods: In this randomised, controlled, parallel-group, non-inferiority, single-blinded, screening-accuracy study, done within the Swedish national screening programme, wo

BACKGROUND: Irritable bowel syndrome (IBS) is the major form of functional bowel disorders, where the diagnosis is based on set criteria and characterized by abdominal pain and changes in bowel habits. Epidemiological data, alongside self-reported outcomes, are of interest with regard to IBS, as these factors may need to be addressed to optimize underlying IBS. This study aims to examine the effec

HLA-DR genes are associated with the progression from stage 1 and stage 2 to onset of stage 3 type 1 diabetes (T1D), after accounting HLA-DQ genes with which they are in high linkage-disequilibrium. Based on an integrated cohort of participants from two completed clinical trials, this investigation finds that sharing a haplotype with the DRB1*03:01 (DR3) allele, DRB3*01:01:02 and *02:02:01 have re

The interaction of light with matter played a key role in the establishment of quantum mechanics, and each development of new light sources led to important advances in science, technology and society. An exciting area of physics has been opened with the new millennium, attosecond physics, where the motion of electrons can be studied at the fastest time scale ever reached with light. We review the

Background: Elevated red cell distribution width (RDW) is associated with increased postoperative mortality, but less is known about kidney outcomes. This study investigated the association between elevated preoperative RDW and postoperative worsening of long-term kidney function and incidence of acute kidney injury. Methods: This retrospective cohort study included patients ≥18 yr undergoing nonc

Denna berättelse handlar om hur hypertermi (uppvärmning av tumörer) kan användas tillsammans med strålterapi för att förbättra behandlingsresultat vid cancer, särskilt återkommande bröstcancer. Det föreslås även nya kombinationsmetoder med immunoterapi för att ytterligare förstärka effekten och förbättra patienternas prognos. Berättelsen är en hyllning till minnet av pionjären onkologiläkaren Clae

Background: Long-term data on safety and efficacy of instantaneous wave-free ratio (IFR) vs fractional flow reserve (FFR) in guiding percutaneous coronary intervention (PCI) is lacking. Objectives: This study sought to evaluate the 5-year clinical outcomes of IFR- vs FFR-guided PCI in a real-world setting. Methods: We assessed the 5-year outcomes of all patients undergoing IFR or FFR assessment be

Gravitational interactions were studied by measuring the influence of small external field masses on a microwave resonator. It consisted of two spherical mirrors, which acted as independent pendulums individually suspended by strings. Two identical field masses were moved along the axis of the resonator symmetrically and periodically between a near and a far position. Their gravitational interacti
