Majorana sweet spots in three-site Kitaev chains

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

Low Migratory Connectivity and Use of Multiple Non-Breeding Sites in American Golden-Plovers Breeding Across the Nearctic Tundra

Aim: Many populations of migratory birds are currently declining. Understanding space use throughout the entire annual cycle, as well as migratory connectivity (i.e., geographic linkage of individuals and populations across different stages of the annual cycle), can improve our ability to identify factors driving population declines and influencing extinction risk. The main objectives of our study

Method comparison of indirect assessments of understory leaf area index (LAI_u) : A case study across the extended network of ICOS forest ecosystem sites in Europe

Leaf area index (LAI) is a key ecological indicator for describing the structure of canopies and for modelling energy exchange between atmosphere and biosphere. While LAI of the forest overstory can be accurately assessed over large spatial scales via remote sensing, LAI of the forest understory (LAIu) is still largely ignored in ecological studies and ecosystem modelling due to the fact that it i

A glycyl radical site in the crystal structure of a class III ribonucleotide reductase

Ribonucleotide reductases catalyze the reduction of ribonucleotides to deoxyribonucleotides. Three classes have been identified, all using free- radical chemistry but based on different cofactors. Classes I and II have been shown to be evolutionarily related, whereas the origin of anaerobic class III has remained elusive. The structure of a class III enzyme suggests a common origin for the three c

Russian internet news sites, 2008–2018 : Fostering an informed citizenry?

Since Perestroika, Russian journalism has gone through a liberalization. However, the short lived apex of journalistic freedom that took place in the late 1980s and early 1990s was followed by a setback in particular since Putin’s accession to power in 2000. The situation for the freedom of the daily press has stagnated. Despite this, the findings based on qualitative text analysis of news article

A blood test to monitor bee health across a European network of agricultural sites of different land-use by MALDI BeeTyping mass spectrometry

There are substantial concerns about impaired honey bee health and colony losses due to several poorly understood factors. We used MALDI profiling (MALDI BeeTyping®) analysis to investigate how some environmental and management factors under field conditions across Europe affected the honey bee haemolymph peptidome (all peptides in the circulatory fluid), as a profile of molecular markers represen
