Old-growth forests uniquely support biodiversity while serving as some of the planet's most important carbon stocks. The influence of tree and stand age on carbon flux dynamics remains debated—an urgent question as climate-driven disturbances may reshape forest age structures and in situ carbon storage. To clarify these relationships in Fagus sylvatica , systems, we examined a unique dataset of 3,
Time-interleaved ADCs are a key building block in mm-wave receivers, where the use of multi-GHz signal bandwidths requires high-performance wide-band data conversion. It is therefore necessary to explore the beamforming receiver system impact of different time-interleaved ADC parameters and limitations, such as number of interleaved channels, mismatches between channels, non-idealities of the subA
As immersive technologies expand in education, a gap persists between teachers’ familiarity with virtual reality (VR) tools and effective pedagogical use. This study designed, implemented, and evaluated a 60-h VR Trainer Training Program using Educational Design Research (EDR) and the Taba-Tyler curriculum model. Sixteen teachers participated in a needs analysis, followed by 42 in-service teachers
Early kidney function decline may be associated with reduced filtration of middle-sized molecules, currently defined as selective glomerular hypofiltration syndrome (SGHS), and driven by the accumulation of atherosclerosis-promoting proteins. We aimed to investigate whether SGHS and other markers of kidney function are associated with subclinical atherosclerosis as evaluated by intima-media thickn
Syphilis has re-emerged as a public health threat during the 21st century, and updated knowledge of the epidemic and its drivers is needed to halt this worrying development. We present data on the incidence of syphilis in the south Swedish region Skåne from 2007 to 2022 to determine the burden of disease, changes in risk groups, as well as routes for testing. To get a picture of the burden of syph
Background: Late effects of polio (LEoP) is a progressive condition leading to a lifelong disability that can affect mental health. There is limited knowledge of depressive symptoms and associated factors in people with LEoP. Objective: To assess the occurrence of depressive symptoms in people with LEoP and explore the association with sociodemographic and disability-related factors. Design: Cross
The chemical industry, essential to economic growth and innovation, faces critical environmental sustainability challenges, notably pollution, emissions, and intensive resource use. Motivated by the need for practical tools to address these issues, this research develops a structured, comprehensive framework to assess and enhance environmental sustainability within the chemical sector. The framewo
Catalytic active phases are often separated from inactive ones by their appearance/removal in heating/cooling experiments. Such experiments can reveal ignition, extinction, and often an associated hysteresis. The corresponding behavior and hysteresis under rapid gas composition changes in the milliseconds regime remain largely unexplored. However, such experiments can potentially be highly rewardi
The differentiation of proplastids into chloroplasts is driven by light and closely linked to the process of chlorophyll biosynthesis. Chloroplasts, while essential for photosynthesis, also generate reactive oxygen species (ROS), necessitating robust antioxidant mechanisms such as superoxide dismutases (SODs). SODs catalyze the detoxification of superoxide radicals to molecular oxygen and hydrogen
ZnS nanoparticles co-doped with Ni–Cr and Ni–Cu were synthesized by chemical precipitation and systematically examined for structural, optical, magnetic, and magneto-transport properties. All samples retained the cubic zinc blende phase with nanoscale crystallinity. Optical studies showed that Ni doping induced bandgap narrowing through sp-d exchange, while Cu and Cr introduced Burstein-Moss-type
Background: Right ventricular dysfunction (RVD) is a marker of adverse outcomes in heart failure (HF). We used a 5-point RVD score to describe three phenotypes (preserved RV function, RVD and RV failure) and investigated their relationhip with cardiac function and their contribution to risk stratification. Methods: Patients (n = 201) with HF, undergoing right heart catheterization and echocardiogr
Aim: This study evaluates the health effects of plant-based dairy alternatives in healthy individuals and those with Inflammatory Bowel Disease (IBD). Specifically, it investigates whether replacing one daily meal with a plant-based alternative has a positive impact on intestinal microbiota composition and gut health. It also investigates whether the effect of probiotic bacteria in yogurt depends
Water structure is crucially important to protein function and catalysis and can be conserved throughout related proteins despite differences in sequence. The complex hydrogen-bonding networks formed by water molecules and protein residues have been studied extensively, and graph-theory-based methods have frequently been used to describe these networks. Although there exist a number of tools which
The use of organic active materials in redox flow batteries (RFBs) presents a promising approach to sustainable large-scale energy storage. However, the stability of nonaqueous organic RFB electrolytes is generally limited by degradation reactions that cause capacity fade. These reactions are commonly thought to convert redox-active organics to products that are no longer electrochemically active.
Closed-form conditions for bound states in the continuum are derived for planar, cylindrical, and spherical cavities enclosed by metasurfaces with electric and magnetic response. While the combined response in lossless systems enables field confinement in arbitrarily small cavities, the gain-enabled bound states in the continuum are found to coalesce with a laser mode, leading to intriguing single
Cancer cells exhibit phenotypical plasticity and epigenetic reprogramming that allows them to evade lineage-dependent targeted treatments by adopting lineage plasticity. The underlying mechanisms by which cancer cells exploit the epigenetic regulatory machinery to acquire lineage plasticity and therapy resistance remain poorly understood. We identified zinc finger protein 397 (ZNF397) as a bona fi
When children display disruptive behaviour problems at school or at home, their re-lationships with others are affected. Taking a systems perspective into account, where all parts of a system mutually in uence each other, and considering the reciprocal nature of interactions which imply that children are in uenced by and in uence their close surroundings, the present study seeks to examine differeWhen children display disruptive behaviour problems at school or at home, their relationships with others are affected. Taking a systems perspective into account, where all parts of a system mutually influence each other, and considering the reciprocal nature of interactions which imply that children are influenced by and influence their close surroundings, the present study seeks to examine diffe
Cambodia’s opening of Techo International Airport and the consolidation of the Bakong digital payment system signal a shift towards a more state-led and financially sophisticated development model. These initiatives reflect the Cambodian state’s expanding role in planning, financing and governing large-scale infrastructure and digital systems, deepening direct participation in development. While d
