A piece of lead with imprints from a coin die and the early minting in Lund. At an archaeological excavation in central Lund in the early 1970s a very unusual find was retrieved: a piece of lead with several imprints from a coin die. The motif and the runic inscription on the lead plate indicate that the die derives from Sven Estridsen’s minting during his late years as king of Denmark. The find i

We apply the statistical sparse jump model, a recently developed, interpretable and robust regime-switching model, to infer key features that drive the return dynamics of the largest cryptocurrencies. The algorithm jointly performs feature selection, parameter estimation, and state classification. Our large set of candidate features are based on cryptocurrency, sentiment and financial market-based

Perovskite solar cells (PSCs) have demonstrated rapid advancements in power conversion efficiency (PCE) in recent years, reaching 25.7% within a decade. However, the stability of PSCs lags behind in comparison, with short lifetimes being a major obstacle to commercialization. The various layers and interfaces within PSCs play a significant role in both PCE and stability. Spiro-OMeTAD is the most c

Lead halide perovskites (LHPs) photoelectrodes for photoelectrochemical (PEC) water splitting are promising candidates for solar-to-fuel conversion. However, the poor stability of LHPs in aqueous electrolyte media, together with the toxicity of lead, restricts the practical application of LHP photoelectrodes. Herein, we report the first-ever colloidal synthesis of quaternary Cu1.4Ag0.6BiI5 nanocry

As the adverse impacts of hydrological extremes increase in many regions of the world, a better understanding of the drivers of changes in risk and impacts is essential for effective flood and drought risk management and climate adaptation. However, there is currently a lack of comprehensive, empirical data about the processes, interactions, and feedbacks in complex human-water systems leading to

We coordinate interconnected agents where the control input of eachagent is limited by the control input of others. In that sense, the sys-tems have to share a limited resource over a network. Such problems canarise in different areas and it is here motivated by a district heating ex-ample. When the shared resource is insufficient for the combined needof all systems, the resource will have to be s

BACKGROUND: Patients with chronic respiratory failure treated with long-term oxygen therapy (LTOT) often have severe breathlessness, impaired exercise performance, and high but variable mortality that is difficult to predict. We aimed to evaluate breathlessness and exercise performance upon starting LTOT as predictors of overall and short-term mortality.METHODS: This was a longitudinal, population

PURPOSE: To explore if aspects of the physical home environment are related to rehabilitation outcomes among community-living persons poststroke.BACKGROUND: Research demonstrates that healthcare environments are important for high-quality care and that the design of the physical environment is associated with improved rehabilitation outcomes. However, relevant research focusing on outpatient care

If the use of military force is neither compatible with loving one's enemies nor better at countering oppression and mass killing than nonviolent methods, why should Christians engage in it?

There has been widespread debate about whether the way in which we measure economic activity is fit for purpose in the twenty-first century. One aspect to this debate is to move away from measuring a nation’s income (GDP), towards monitoring a nation's assets (their inclusive wealth), as a better indicator of sustainable economic development. We provide the first critical comparison of the approac
