Context. The chemical makeup of a star provides the fossil information of the environment where it formed. Under this premise, it should be possible to use chemical abundances to tag stars that formed within the same stellar association. This idea - known as chemical tagging - has not produced the expected results, especially within the thin disk where open stellar clusters have chemical patterns
Tropical America is currently experiencing the establishment of a new apex insect predator, the Paleotropical dragonfly Hemianax ephippiger (Odonata: Aeshnidae). H. ephippiger is migratory and is suggested to have colonised the eastern Neotropics by chance Trans-Atlantic displacement. We report the discovery of H. ephippiger at three new locations in the Caribbean, the islands of Bonaire, Isla de
In the summer of 1988, during the premiership of Mir-Hussein Mousavi, thousands of opponents of the Islamic Republic were extrajudicially executed while in prison. Newly published evidence from Amnesty International shows that Mousavi, despite his denials, was aware of the executions, casting a dark shadow over the reformist movement in Iran.
Many earlier works were devoted to the study of the breakdown of superconductivity in type-II superconducting bounded planar domains, submitted to smooth magnetic fields. In the present contribution, we consider a new situation where the applied magnetic field is piecewise-constant, and the discontinuity jump occurs along a smooth curve meeting the boundary transversely. To handle this situation,
This essay raises the question whether citizens in the digital age can learn from how credibility is treated in international negotiations. Negotiators face problems both in attempting to send credible signals and in making credibility assessments of received signals. Several studies, starting with Schelling's seminal analysis of commitments, indicate that credible signals are those that are someh
Accidents nearby work zones are a persistent road safety problem in many European countries. The Conferenceof European Directors of Roads (CEDR) has initiated and finances the IRIS project (Incursion Reduction toIncrease Safety in road work zones) with the aim to collect and share information about best practices in temporarytraffic management at road works. An analysis of work zone accidents and
The objective of this study is to improve the quality of the hardware of the existing Lund impedance tomography system. Improvement in the current generator and different isolation proposals are presented.
Walking as a means of transportation is a key feature in sustainable urban design, but few studies have examined the influence of micro-level environmental features, such as vegetation and street lighting, on perceived safety and people’s choice to walk. This study applied a non-explicit approach to examine the relationship between greenery, street lighting, perceived safety, and walking in an urb
Social deprivation and marginalization in urban areas are hardships that are not necessarily limited to developing countries. Around 80 million Europeans today live in conditions that fall within the definition of poverty. However, certain areas are more prone to affliction than others. Such estates usually consist of concrete slab high-rise buildings and are often characterized by high levels of
Our understanding of the rises of animal and cancer multicellularity face the same conceptual hurdles: what makes the clade originate and what makes it diversify. Between the events of origination and diversification lies complex tissue organization that gave rise to novel functionality for organisms and, unfortunately, for malignant transformation in cells. Tissue specialization with distinctly s
We investigated how legacies of land use and climate affected the microbial use of organic matter (OM) along a tropical climate gradient in Ethiopia. Four levels of land-use intensity ranging from croplands to pristine forests were assessed along a gradient from cool and moist high altitude (MAT = 16°C, MAP = 2,200 mm) to hot and dry lowland sites (MAT = 20°C, MAP = 1,050 mm). We resolved the biom
Based on first-hand ethnographic insights into Shi‘i religious groups in the Middle East and Europe, this book examines women’s resistance to state as well as communal and gender power structures. It offers a new transnational approach to understanding gender agency within contemporary Islamic movements expressed through language, ritual practices, dramatic performances, posters, and banners. By l
The Chinese government is acutely aware of the problem of climate change. In the crucial crossroads, carbon emissions trading scheme (ETS), a kind of market-based instruments based on cap-and-trade, has become the new hope of carbon governance and the most important measure adopted to mitigate climate change. Based on the description and analysis on the ongoing process of pilot ETS in China and it
Linear chromosomes of eukaryotic cells require the presence of functional nucleoprotein terminal structures, known as telomeres, to protect the integrity of the genome. The telomere is a highly dynamic and regulated structure constituted by short tandem DNA repeats rich in guanine nucleotides that extent as double-stranded DNA ending in a single-stranded 3′ overhang. An abundant number of proteins
