Although cuprate high-temperature superconductors were discovered already in 1986 the origin of the pairing mechanism remains elusive. While the doped compounds are superconducting with high transition temperatures Tc, the undoped compounds are insulating due to the strong effective Coulomb interaction between the Cu 3d holes. We investigate the dependence of the maximum superconducting transition
The development of microwave photon detectors is paving the way for a wide range of quantum technologies and fundamental discoveries involving single photons. Here, we investigate the photon emission from a microwave cavity and find that distribution of photon waiting times contains information about few-photon processes, which cannot easily be extracted from standard correlation measurements. The
This paper considers a formation shape control problem for point agents in a two-dimensional ambient space, where the control is distributed, is based on achieving desired distances between nominated agent pairs, and avoids the possibility of reflection ambiguities. This has potential applications for large-scale multi-agent systems having simple information exchange structure. One solution to thi
As researchers we need to be relevant, not only to our peers, but also to external stakeholders. We need to make a societal impact. In this study we explore the extent and characteristics of the implications for external stakeholders identified in articles on Business Angels published in Venture Capital: An International Journal of Entrepreneurial Finance between 1999 and 2017. We identified 75 ar
Forecasts of ecological dynamics in changing environments are increasingly important, and are available for a plethora of variables, such as species abundance and distribution, community structure and ecosystem processes. There is, however, a general absence of knowledge about how far into the future, or other dimensions (space, temperature, phylogenetic distance), useful ecological forecasts can
Educational collaboration activities are generally under-researched part of the interactive learning between universities and industry. The study based on 529 Master of Science (MSc) theses from a major Swedish engineering school, the faculty of engineering LTH at Lund University, shows that MSc theses are a frequently used collaboration mechanism between university and industry in engineering edu
On 1 July 2018, a new consent-based legislation entered in force in Sweden, making it illegal to perform sexual intercourse with a person who was not participating voluntarily. The main argument in this chapter is that in Sweden, this legal shift was the result of a discursive process that since the mid-1990s, in particular, was taking place in news reports and debate about the legal handling of a
The PHENIX experiment has studied nuclear effects in p+Al and p+Au collisions at sNN=200GeV on charged hadron production at forward rapidity (1.4<η<2.4, p-going direction) and backward rapidity (-2.2<η<-1.2, A-going direction). Such effects are quantified by measuring nuclear modification factors as a function of transverse momentum and pseudorapidity in various collision multiplicity selections.
Several models of physics beyond the Standard Model predict the existence of dark photons, light neutral particles decaying into collimated leptons or light hadrons. This paper presents a search for long-lived dark photons produced from the decay of a Higgs boson or a heavy scalar boson and decaying into displaced collimated Standard Model fermions. The search uses data corresponding to an integra
The study has been performed in order to give a contribution to the knowledge of the conjunctival cytology in Sjögren's syndrome. Exfoliated cells were obtained by a tampon from the inferior conjunctival sac of 11 patients affected by primary or secondary Sjögren's syndrome; the material was placed onto a microscope slide and it was stained with May-Grumwald-Giemsa, after the ferning test had been
Version management is a prerequisite for digital information flow between phases in the planning and building processes. Information evolves over time and many parties retrieve information from the various phases. The aim of this article is to evaluate versioning methods, focusing on geodata buildings in the 3D cadastre process. The main attention in the evaluation is on the comprehensive ISO stan
Credit expansion is the trend of households gaining access to more credit. It is correlated with increasing socio-economic heterogeneity of indebted homeowners. Increasing heterogeneity implies that a more diverse span of homeowners is put at risk of foreclosure. This empirical study explores socio-economic heterogeneity in the case of Swedish debtors in foreclosure between 2000 and 2014. Employin
In this letter, a recently conducted measurement campaign in two suburban scenarios for investigating the low-height air-to-ground channels is presented. A universal-software-radio-peripheral-based channel sounder on-board an unmanned aerial vehicle (UAV) was exploited to record the real-time downlink signals of the live Long Term Evolution networks. Several horizontal flights at different heights
