To date, the most efficient perovskite solar cells (PSCs) require hole-transporting materials (HTMs) that are doped with hygroscopic additives to improve their performance. Unfortunately, such dopants negatively impact the overall PSCs stability and add cost and complexity to the device fabrication. Hence, there is a need to investigate new strategies to boost the typically modest performance of d
The combination of digital breast tomosynthesis (DBT) with other imaging modalities has been investigated in order to improve the detection and diagnosis of breast cancer. Mechanical Imaging (MI) measures the stress over the surface of the compressed breast, using a pressure sensor, during radiographic examination and its response has shown a correlation with the presence of malignant lesions.

The current rate of residential building renovations in Europe is inadequate and attributable to the lack of integrated solutions in the market supported by appropriate business models. One-stop-shop (OSS) offers an innovative business approach, and it is acknowledged by the European Commission, in the Directive 2018/844/EU, as a transparent advisory and facilitating tool for the establishment of
Food, hygiene, and safety are critical in healthcare institutions, especially those in which patients are vulnerable against diseases triggered by food prepared under improper conditions. In the United Kingdom, almost 400 healthcare institutions were found to need significant improvements to their food preparation standards (ITV News, 2016). Such institutions still rely on traditional pen and pape
This article provides a critical literature review on the regional determinants of environmental innovation. The analysis of the relevant literature on supply-side factors, demand-side factors, and institutional factors reveals the importance of regional determinants in green technology development. Specifically, regional R&D collaborations, university-industry collaborations, and technologica
This thesis is composed of four papers, the first two show the attempts made to extend the Pythia event generator to simulate heavy-ion collision events. The other two papers show methods to improve the hadronization mechanism in the Pythia model for a bettter agreement with the experimental data of pp and heavy-ion collisions.Paper I introduces a new model named Angantyr for heavy-ion collision e
Rare Earth (RE) ion doped nanomaterials are promising candidates for a range of quantum technology applications. Among RE ions, the so-called Kramers' ions possess spin transitions in the GHz range at low magnetic fields, which allows for high-bandwidth multimode quantum storage, fast qubit operations as well as interfacing with superconducting circuits. They also present relevant optical transiti
This paper treats the problem of control signal saturation caused by feedforward control from measurable load disturbances. An efficient feedforward compensator will often give significant peaks in the control signal at fast changes in the load disturbance. These peaks may cause the control signal to reach a saturation limit. In the paper, it is shown that the anti-windup function may cause unnece
Aims: An observational nationwide all-comers prospective register study to analyse outcomes after coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in unprotected left main coronary artery (LMCA) disease. Methods and results: All patients undergoing coronary angiography in Sweden are registered in the Swedish Web-system for Enhancement and Development of Evidence-b
COVID-19 was first identified in Wuhan City in December 2019 and spread throughout Hubei Province and other parts of China. After causing significant morbidity and mortality in China, by February 2020, it had spread to numerous other countries, infecting millions of people and causing a large number of deaths across the world. The COVID-19 pandemic put a burden on almost all areas of the world inc
Sustainable development rests on, among other things, the ability of policy to stimulate corporate actors to improve their environmental performance. Yet policy design and implementation is a challenging task in this area. This paper investigates this issue by examining the ability of the UK Emissions Trading Scheme to foster corporate sustainability from two perspectives: (a) its institutional fr
We derive asymptotically exact results for the charge and spin densities far away from finite systems (atoms and molecules) and far outside solid surfaces. These results are then used to obtain the correct asymptotic form of the exchange-correlation potential of density-functional (DF) theory and to prove that, for all systems, the eigenvalue of the uppermost occupied DF orbital equals the exact i
