We report on the preparation of high performance field-effect transistors (FETs) based on large areas of aligned films of a TTF derivative, namely, tetrakis-(octadecylthio)-tetrathiafulvalene (TTF-4SC18). TTF-4SC18 assembles into one-dimensional stacks in which the long alkyl chains promote intermolecular π-π overlapping due to their extremely closely packed nature. The films were prepared from so
Desire for life and protecting lives has come to the fore during the pandemic. Borders have been closed to stop the spread of Covid-19. The virus does not respect borders, yet physical distance is crucial. Three things have become clear. One is the level of uncertainty about which measures are most efficient. The other is that the neo-liberal philosophy with “just in time” deliveries on a global m
Tendons fulfill an important musculoskeletal function by enabling energy-efficient force transmission between muscles and bones. The tendon is a collagen-rich connective tissue that adapts to mechanical loading through mechanobiological processes. The tendon contains a hierarchical collagen fiber structure that displays complex mechanical behaviour by storing and dissipating energy. Current unders
Computational notebooks (e.g. Jupyter notebook) are a popular choice for interactive scientific computing to convey descriptive information together with executable source code. The user can annotate the scientific development of the work, the methods applied, describe ancillary data or the analysis of results, with text, illustrations, figures, and equations. Such ‘executable’ documents provide a
In language acquisition it is important to imitate the native speakers of the language. For the young child it is natural to imitate both the language and the behaviour of the culture. Imitation, or adaptation (Markham 1997), is also useful in second language acquisition to learn how to pronounce the words and to learn the prosody of the language. For most people it is difficult to learn to speak
Risk and vulnerability analyses are a required decision support tool in processes to improve societal safety and crisis preparedness at national, regional and local levels in several European states. Analyses result in risk images, which are the stakeholders’ views of events that must be addressed in planning processes related to topics such as land use and crisis management. Hence, risk and vulne
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide according to the world health organization. It is a disease characterized by chronic inflammation and emphysema, and cigarette smoking is the main cause of COPD development. There are several forms of stress present in the lungs of COPD patients, such as smoking induced endoplasmic reticulum stress or hypoxi
Background: Creativity is a multifaceted, complex, activity, and as such is an overarching function of the brain rather than being confined to a specific structure or region. Alzheimer's disease effects several cognitive domains involved in the creative process of producing art. Objective: We analyze the art of a well-known Swedish visual artist who suffered from Alzheimer's disease to determine i
How do humans construct their mental representations of the passage of time? The universalist account claims that abstract concepts like time are universal across humans. In contrast, the linguistic relativity hypothesis holds that speakers of different languages represent duration differently. The precise impact of language on duration representation is, however, unknown. Here, we show that langu
The size of the authentication tag represents a significant overhead for applications that are limited by bandwidth or memory. Hence, some authenticated encryption designs have a smaller tag than the required privacy level, which was also suggested by the NIST lightweight cryptography standardization project. In the ToSC 2022, two papers have raised questions about the IND-CCA security of AEAD sch
This dissertation shows how the intersection between German and Yiddish became an important but largely forgotten site of literary production in the long twentieth century. Beginning in the late eighteenth century, German and Yiddish came to be associated with divergent trajectories of Jewish modernity and were often understood to represent either side of a series of charged dichotomies, such as W
Couplings of microscopic stochastic models to deterministic macroscopic ordinary and partial differential equations are commonplace in numerous applications such as catalysis, deposition processes, polymeric flows, biological networks and parametrizations of tropical and open ocean convection. In this paper we continue our study of the class of prototype hybrid systems presented in [8]. These mode
Providing humoral immunity, antibody-secreting plasma cells and their immediate precursors, the plasmablasts, are generated in systemic and mucosal immune reactions. Despite their key role in maintaining immunity and immunopathology, little is known about their homeostasis. Here we show that plasmablasts and plasma cells are always detectable in human blood at low frequency in any unimmunized dono
Fungi are among the most diverse and ecologically important kingdoms in life. However, the distributional ranges of fungi remain largely unknown as do the ecological mechanisms that shape their distributions1,2. To provide an integrated view of the spatial and seasonal dynamics of fungi, we implemented a globally distributed standardized aerial sampling of fungal spores3. The vast majority of oper
Introduction: Social robots are accompanied by high expectations of what they can bring to society and in the healthcare sector. So far, promising assumptions have been presented about how and where social robots are most relevant. We know that the industry has used robots for a long time, but what about social uptake outside industry, specifically, in the healthcare sector? This study discusses w
Objective: This study examined the prevalence and long-term survival of atrial fibrillation (AF) in the older population. Methods: Data was recruited from the longitudinal SNAC study from baseline (2001–2004) for up to 10 years. Results: The population comprised 6,904 persons (59% women) (mean age 73.9 years). The prevalence of AF was 4.9% and increased with age. The hazard ratio (HR) for death in
The orientation of four species of passerine long-distance migrants was studied in spring and autumn by orientation cage experiments during the twilight period after sunset in Sweden. Two groups of migrants from the Palaearctic-African migration system were used: migrants wintering mainly north of the magnetic equator in west Africa (pied flycatcher, Ficedula hypoleuca, and redstart, Phoenicurus p
