We propose that the crystallinity of two-dimensional (2D) materials is a crucial factor for achieving highly effective work function (WF) modification. A crystalline 2D MoO3 monolayer enhances substrate WF up to 6.4 eV for thicknesses as low as 0.7 nm. Such a high WF makes 2D MoO3 a great candidate for tuning properties of anode materials and for the future design of organic electronic devices, wh

The recent warming trend, and associated shifts in growing season length, challenge the principle of uniformitarianism, i.e., that current relations are persistent over time, and complicates the uncritical inferences of past climate from tree-ring data. Here we conduct a comparison between tree-ring width chronologies of Pinus sylvestris L. (Scots pine), Picea abies (L.) Karst. (Norway spruce) and

This paper provides a coherent review of district heating in Denmark, exploring past, present and future perspectives. Danish district heating is known as unique internationally in terms of heat planning strategies, technical solutions and combinations, energy efficiency and sustainability, ownership models and financing, and it has captured the attention of district heating communities and stakeh

Photostability is critical for long-term solar cell operation. While light-triggered defects are usually reported as evidence of material degradation, we reveal that the formation of certain defects in metal halide perovskites is crucial for protection against intense or prolonged light exposure. We identify an inherent self-regulating cycle of formation and recovery of ionic defects under light e

This paper explores the history of wind power technologies and the integration of wind energy in the Danish energy system. It does so focusing particularly on historical events, socio-cultural and socio-political changes and priorities that were important on this technological journey. From the first primitive wind turbines in the late 1800s, to the world wars, through the energy- crisis in the 70

This database describes churches and monasteries in the country’s territory, lists the immovable property owned by the Orthodox Christian Church of Georgia, and thematically categorizes the epistles of the Catholicos-Patriarch of Georgia. Given the limited access to information, the data do not cover the occupied territories of Abkhazia and South Ossetia.

Different methods for evaluation of displacement and strain fields based on phase field crystal (PFC) simulations are shown. Methods originally devised for molecular dynamics (MD) simulations or analysis of high-resolution microscopy images are adapted to a PFC setting, providing access to displacement and strain fields for systems of discrete atoms, such as in MD, as well as to continuous deforma

Background:Gaming and gambling are frequently reported from child and adolescent psychiatry and school health care. Swedish epidemiological data show that 1.3% of the population meet the criteria for gambling disorder. Risk factors are male gender, young age, single status and being born outside Sweden. Both problem gaming and gambling are associated with compulsion, psychiatric and physical sympt

This dissertation explores, illuminates, and analyses Sámi feminist knowledges, conceptualised as diverse and fluid feminist knowledges that both arise within and create Sámi realities. Centrally, it contributes to and exemplifies Sámi inquiry and conversations where different people continuously create and re-create Sámi feminisms in various contexts. This study focuses on feminist articulations

This thesis develops a general formalism for continuous feedback control in quantum systems. The main result is a quantum Fokker-Planck master equation describing the joint dynamics of a quantum system and a detector with finite bandwidth. For a fast detector, this equation can be reduced to a Markovian master equation for the system dynamics. In particular, the formalism is amenable to analyticalThis thesis devolops a general formalism for continuous feedback control in quantum systems.

Background: Despite significant symptomatic overlap between behavioral variant frontotemporal dementia (bvFTD) and primary psychiatric disorders (PPDs), a potential overlap in their structural anatomical changes has not been studied systematically. Methods: In this magnetic resonance imaging-based meta-analysis, we included studies on bvFTD, schizophrenia, bipolar disorder, and autism spectrum dis

Acrolein, as one of the most hazardous aldehydes, can be formed among the carbonyls from the combustion of bio-fuels or mixtures of bio- and conventional fuels. Moreover, acrolein is also an important combustion intermediate in the oxidations of higher unsaturated hydrocarbons. A deep understanding of acrolein combustion chemistry will be useful for the kinetic modeling of higher hydrocarbons and

Along with the ever-expanding interest in brands, the brand orientation concept has since its inception in the early 1990s steadily received more and more attention from scholars and practitioners alike. Brand orientation ultimately captures how organisations can develop sustainable competitive advantages in the form of brands.

Motivated by a need to characterize transient behaviors in large network systems in terms of relevant signal norms and worst-case input scenarios, we propose a novel approach based on existing theory for matrix pseudospectra. We extend pseudospectral theorems, pertaining to matrix exponentials, to an input-output setting, where matrix exponentials are pre- and post-multiplied by input and output m

Many long-term childhood cancer survivors suffer from treatment-related late effects, which may occur in any organ and include a wide spectrum of conditions. Long-term follow-up (LTFU) is recommended to facilitate early diagnosis and to ensure better health outcomes. Due to the heterogeneity of these sequelae, different specialists work together in the diagnosis and treatment of these conditions.

The role of mutations have been subject to many controversies since the formation of the Modern Synthesis of evolution in the early 1940ties. Geneticists in the early half of the twentieth century tended to view mutations as a limiting factor in evolutionary change. In contrast, natural selection was largely viewed as a “sieve” whose main role was to sort out the unfit but which could not create a

Neural network training and validation rely on the availability of large high-quality datasets. However, in many cases only incomplete datasets are available, particularly in health care applications, where each patient typically undergoes different clinical procedures or can drop out of a study. Since the data to train the neural networks need to be complete, most studies discard the incomplete d
