Minimal Kitaev chains, composed of two quantum dots connected via a superconductor, have emerged as an attractive platform to realize Majorana bound states (MBSs). These excitations exist when the ground state is degenerate. The additional requirement of isolating the MBS wave functions further restricts the parameter space to discrete sweet spots. While scaling up to Kitaev chains with more than
The coherence factors of quasiparticles in a superconductor determine their properties, including transport as well as their susceptibility to electric fields. In this work, we propose a way to infer the local coherence factors using local transport to normal leads. Our method is based on measuring the local current through a lead as the coupling to a second one is varied; the shape of the current
Rochechouart, south-west France, is a complex impact structure. Here, we present the first report of shock barometry of quartz from what are likely parautochthonous basement units at depth, based on samples from the 2017 C.I.R.I.R drilling campaign. The crystallographic orientations of 725 sets of PDFs in 512 quartz grains in samples from four drill cores were measured. We find basal PDFs (Brazil
Context: Chronic dyspnea is subjective but with objective (measurable) consequences. It is often poorly assessed because people have modified their lifestyles to avoid exertion that generates dyspnea. Objectives: This study sought any relationship between respondents’ self-reported long-term breathlessness limiting exertion (hereafter chronic dyspnea) and distance travelled from the room in which
Complicates and challenges widespread perceptions of Swedish actor Anita Ekberg An examination of an icon of glamour and excess An appreciation of the work of celebrity and performance A look at a star across nations, genres and phases of life A range of critical approaches in the study of a key star and celebrity Anita Ekberg was a major international star now chiefly remembered for her half-hour
Occupational exposure to the carcinogen hexavalent chromium [Cr(VI)] occurs during stainless steel production, welding, and chrome plating. Two sister-projects, SafeChrom and SAM-Krom, were initiated in Sweden and Denmark, respectively, to inform stakeholders, decision-makers and regulators on current occupational exposure to Cr(VI), and preventive measures prior to revision of national occupation
The fascination with the “Eastern Wisdom” exhibited among esoteric movements in the late nineteenth and early twentieth century is often understood as an interest in spirituality. Existing research has focused on how these movements took an interest in beliefs in doctrines like karma and reincarnation, as well as in practices of meditation and divination. Although this characterisation is broadly
Large igneous provinces (LIPs) are excellent spatial and temporal geological recorders. However, our understanding of LIPs is hindered by a lack of preservation and alteration of many LIPs through deep time. Several LIPs have been emplaced in the Rhyacian. These LIPs demonstrate a connection across the Superior, Wyoming and North Atlantic cratons. In this study we use new U-Pb ID-TIMS baddeleyite
Aims Acute myocardial infarction (AMI) is associated with significant loss-of-life expectancy, particularly among younger females. Addressing risk factors is crucial for optimizing prevention strategies. The aim of this study was to describe the trends in risk factors and clinical outcomes in a nationwide cohort of young AMI patients stratified by sex. Methods and results Using Swedish registries,
Background: In Sweden 70,000 people suffer fragility fractures annually, including 16,000 hip fractures with one-year mortality of up to 25%. Strategies to prevent falls, improve physical function, and enhance bone strength have shown mixed results. Aim: To evaluate the incidence of hip and other fragility fractures following a fracture prevention intervention and assess baseline risk factors for
The transition to smart, wearable, and flexible optoelectronic devices that communicate with each other and perform neuromorphic computing at the edge, is a major goal in next-generation optoelectronics. These devices are expected to carry out their regular tasks while being supported by energy-efficient, in-memory computations. In this study, a lateral flexible device based on cesium lead tribrom
Lytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes that have fueled the hope for sustainable biofuel production since they enhance the breakdown of recalcitrant polysaccharides like cellulose. In the consensus mechanism, their catalytic activity relies on forming an ‘oxyl’, [CuO˙−]+, species at the active site, followed by subsequent hydrogen atom abstraction (HAA) from the s
Theis essay offers an outline of classical modern reflection (sociology, cultural theory, literature) on the constitution and transformation of modernity, its cultural and mental dispositions. The discussion focuses on key themes and experiences of classical modernity: void, crisis and abundance. It is argued that classical modernity may be conceived as a conceptual archive of influential ideas onThe essay offers an outline of classical modern reflection (sociology, cultural theory, literature) on the constitution and transformation of modernity, its cultural and mental dispositions.

Natural salts are minerals formed through natural processes, generally consisting of complex mixtures of ions. In the atmosphere, natural salts are present as aerosol particles, originating from both marine and terrestrial sources. The interaction of these natural salt particles with trace gases, also termed ageing, can influence various atmospheric processes such as cloud properties or atmospheri
Climate change mitigation requires collective efforts, but the fact that the climate issue has become highly polarized may thwart such endeavors. In this article, we examine how negative emotions in response to climate change threats are associated with affective polarization—the tendency to view those from opposing political groups with hostility and bias, and to view those from one's own group m
Purpose: Ultra-low field MRI scanners have the potential to improve health care delivery, both through improved access in areas where there are few MRI scanners and allowing more frequent monitoring of disease progression and treatment response. This may be particularly true in white matter disorders, including leukodystrophies and multiple sclerosis, in which frequent myelin-sensitive imaging, su
A novel family of symmetric squaramide-based LMWGs has been synthesised, functionalized with both dansyl moieties and alkyl chain spacers of different lengths (n = 3 and n = 4 named L1 and L2, respectively). L1 and L2 are able to form hydrogels in the DMSO : H2O mixture in different ratios and concentrations. The gels obtained were characterized by means of rheology, TEM and small angle X-ray scat
Accountability is central for accelerating progress towards achieving the Sustainable Development Goals (SDGs). It means to hold powerful actors answerable for how they turn agreements into action. Governments, who hold the main responsibility for SDG implementation, can in the ideal case be held accountable by voters, parliaments, civil society, and the media, for how they address the SDGs. At th
