Nineteen new, presumably apomictic species of Hieracium sect. Tridentata, namely Hieracium anisodontum, H. bicoloriceps, H. disparifolium, H. ditrichum, H. erectifolium, H. ferox, H. lapsanae, H. luteoviride, H. megaplicatum, H. multifolium, H. paer-haraldii, H. perpendiculum, H. phaeochlorum, H. prasiniceps, H. semirigidum, H. serriolum, H. spinophytoides, H. svensonii, H. xantholineatum, and one
A wideband, compact monopolar patch antenna with an inherent filtering response is presented in this paper. By employing a slot-assisted mode-tailoring technique, the field distributions of several higher-order modes at the patch center are engineered to produce a stable monopolar radiation pattern with enhanced bandwidth. The closed-form analysis indicates that increasing the current intensity at
Following the line of the former Iron Curtain, the European Green Belt links protected areas across 24 countries, and restores key wildlife populations, wetlands and rural livelihoods. Its success proves that rewilding-grounded nature-based solutions can transform war-scarred frontiers into biodiversity-rich, climate-resilient lifelines, and challenges policymakers to replicate such mega-corridors
Objectives: This study explores the dynamics of vaccine rumors during the COVID-19 pandemic, particularly those surrounding messenger RNA vaccines. By employing and developing Hallin’s communication model of credibility spheres, we analyze how controversial ideas regarding vaccine safety gained public attention and challenged established vaccine narratives. Methods: The focal point of the investig
Almost 10 years have passed since microtektites and microkrystites were reported for the Paleocene–Eocene (P–E) boundary in drill cores and outcrop in New Jersey and in ODP Hole 1051B in the western North Atlantic. The glassy spherules were interpreted to reflect an impact trigger for the Paleocene–Eocene Thermal Maximum (PETM). Since then, many detailed studies of sediment strata across the P–E b
Background: Myocardial infarction with non-obstructive coronary arteries (MINOCA) demands prompt mechanistic clarification. Early integration of coronary CT angiography (CCTA) and cardiovascular magnetic resonance (CMR) can refine diagnosis during the acute phase. Methods: Twenty-one consecutive patients (41 ± 10 years; 71% men) presenting with troponin-positive chest pain and unobstructed coronar
This chapter describes methods and procedures that can be used to calculate the absorbed dose distribution based on quantitative SPECT/PET images. In this context, quantitative images mean images corrected for various physical effects (among them are photon attenuation, scatter contribution, dead time) in such a way that the values of each voxel can then be translated into units of activity by a c
Objective: Cystic fibrosis (CF) is a congenital condition caused by mutations in the CF transmembrane conductance regulator (CFTR) gene. CF-related diabetes (CFRD) is a common comorbidity among people with CF (pwCF) and is associated with increased morbidity. Previous in vitro studies have suggested that CFTR dysfunction is involved in the pathogenesis of CFRD. This prospective study aimed to eval
Seasonal temperature fluctuations present a major survival challenge for insects, requiring physiological adaptation that confers resilience to cold stress. However, the hormone mechanisms governing mitochondrial adaptation to overcome cold stress remain poorly understood. Here, we identify that the endogenous ascaroside C9 (asc-C9) acts as a chemical signal that markedly improves survival followi
Starting with remnants of street art and graffiti from the Orange Revolution of 2004, over the Revolution of Dignity in 2013–14, and ending with street art and graffiti created during Russia’s ongoing war of aggression since 2014, this chapter looks at several cases from Ukraine that showcase the different roles street art and graffiti have played in the country’s democratic process.
China plans expanding 49.5 million hectares of new forests by 2050 to strengthen carbon sequestration. However, estimates of the carbon benefits from this expansion rarely consider the effect of 'forest edge', where tree mortality increases under intensified stress from wind, drought, pests, and fire. Here we show that proximity to forest edges substantially reduces biomass carbon storage, and dev
The ability of organisms to change color in response to a change in environmental conditions is widespread across taxa. Predation represents the longstanding hypothesis for the evolution of such coloration plasticity. Yet, tests of the evolutionary drivers of coloration plasticity remain rare. Here, we examine how predation shapes both baseline coloration and coloration plasticity in the Trinidadi
