The introduction of a semiconductor–semiconductor junction is an effective strategy to enhance the photocatalytic performance of perovskite nanocrystal-based systems. Herein, we optimized the synthesis of CsPbX3/Pb4S3Y2 (X, Y = Cl, Br, I) perovskite/chalcohalide heterostructures, whose band alignment can be tuned by the halide composition. As a proof-of-concept, we evaluated the photooxidative cou
We present a canonical series expansion for generalized harmonic functions in the open unit disc in the complex plane that generalizes that recently obtained for the class of (Formula presented.) -harmonic functions.
Freshwater ecosystems in the central Andes provide critical ecosystem services (ES), including water purification, baseflow regulation, groundwater recharge, and cultural and recreational benefits. However, these high-mountain systems are increasingly threatened by changing land use, climate variability, and accelerating pressure on water resources. Understanding local willingness to pay for conse
My study; The Common European Asylum System in Poland; prospects for implementation and legitimacy is a case study of an EU member state, Poland, and its ability to implement lawfully and legitimately the second phase of the Common European Asylum System. The implementation prospects have been investigated through an empirical study on previous implementation performance, administrative capacity a
Sri Lanka has experienced a double-digit unemployment rate for almost three decades. The problem of the country is that there exists a mismatch between the demand for and the supply of the educated labour force, which is reflected in youth unemployment. The aim of the thesis is to explain this mismatch. We use the theories of unemployment, the labour market and human capital applicable to developi
Exposure to extreme temperatures can negatively affect animal reproduction, by disrupting the ability of individuals to produce any offspring (fertility), or the number of offspring produced by fertile individuals (fecundity). This has important ecological consequences, because reproduction is the ultimate measure of population fitness: a reduction in reproductive output lowers the population grow
The purpose of this paper is to show how requirements engineering techniques can be used to structure the development of non-technical aspects of socio-technical systems, such as guidelines. An adapted requirements engineering approach was chosen to elicit requirements for resilience guidelines within an EU Horizon 2020 multi-national project aimed at developing resilience guidelines for crisis ma
Recent discoveries of several Mesolithic sites within the Dagsmosse Basin, south-central Sweden, offer an opportunity to study the lifestyle and skillsets of Mesolithic hunter-gatherer-fishers operating in wetland environments. In this paper, we present a combined archaeological and palaeoecological analysis of a Mesolithic fenland environment using Repetitive-Proxy Pollen Analysis (RPPA) of early
We propose a non-intrusive reduced basis (RB) method for parametrized nonlinear partial differential equations (PDEs) that leverages models of different accuracy. From a collection of low-fidelity (LF) snapshots, parameter locations are extracted for the evaluations of high-fidelity (HF) snapshots to recover a reduced basis. Multi-fidelity Gaussian process regression (GPR) is employed to approxima
At MAX IV Laboratory, the Swedish Synchrotron Radiation (SR) facility, the largest of two rings operates at 3 GeV with a bare lattice emittance of 330 pm rad. Upgrade plans are under consideration aiming at a gradual reduction of the emittance, in three stages: a short-term with an emittance reduction of 20% to 40%, a mid-term with an emittance reduction of more than 50% and a long-term with an em
Context. Transmission spectroscopy is one of the most powerful techniques used to characterize transiting exoplanets, since it allows for the abundance of the atomic and molecular species in the planetary atmosphere to be measured. However, stellar lines may bias the determination of such abundances if their center-To-limb variations (CLVs) are not properly accounted for. Aims. This paper aims to
The MAX laboratory at Lund University, Sweden, today operates an accelerator system consisting of a 100 MeV racetrack microtron and a 550 MeV storage ring (MAX I). At the moment (July 1994) a new storage ring MAX II is near completion and will start first injections within 2 months. This work gives an overview of the MAX II project including the first beamlines and a description of the accelerator
The late nineteenth and early twentieth century saw a widespread interest in Asian religion within European and American esotericism. Whereas most of that interest was directed toward India, a number of representatives of the early twentieth-century esoteric environment turned toward East Asia in order to find what they hoped to be a spiritual solution to the problems of their time. One of these i
Fetal programming may arise from prenatal exposure and increase the risk of diseases later in life, potentially mediated by the placenta. The objective of this systematic review was to summarize and critically evaluate publications describing associations between human placental changes and risk of atopic disorders during childhood. The review adhered to the Preferred Reporting Items for Systemati
When does technological change lead to inclusive prosperity? Research suggests that shared benefits from technological progress require concurrent expansions in education and support from pro-labor institutions. We contribute to the debate by studying electricity adoption in Sweden during the first decades of the 20th century. Exploiting that proximity to hydro-power plants shaped the electricity
Three methods were developed for preparing alginate gels containing cells that are stable in phosphate containing media. In Method I preformed alginate beads containing entrapped cells were treated with polyethyl eneimine followed by glutaraldehyde. In Method II alginate sol was treated with a carbodiimide and N-hydroxysuccinimide (to form active esters), mixed with cells and extruded into calcium
This technical report gives an overview of our submission to task 3 of the DCASE 2024 challenge. We present a sound event localization and detection (SELD) system using input features based on trainable neural generalized cross-correlations with phase transform (NGCC-PHAT). With these features together with spectrograms as input to a Transformer-based network, we achieve significant improvements o
