A recurrent problem in ecology and conservation biology is to estimate the risk of population extinctions. Extinction probabilities are not only imperative for conservation and management, but may also elucidate basic mechanisms of the regulation of natural populations. The usual way of modelling stochastic influence on population dynamics has been to assume that the external noise is uncorrelated

Background: The choice between different attention-deficit/hyperactivity disorder (ADHD) medications depends on different drug attributes. Economic evaluations of drugs often disregard the utility of other attributes compare with the drugs' efficacy. Aims: The aim of this study was to assess patient's preferences and elicit willingness-to-pay (WTP) for different drug attributes in the treatment of

Chronic neural interfaces that are able to record or stimulate neurons in the CNS are valuable instruments in use today and they hold great promise for the future both within neuroscience research and in the clinic. However, a major obstacle is that they show a decline in performance over time. Many different approaches to improve the interface designs are gradually evaluated in hope of overcoming

We analyze the classical problem of the interaction between two charged surfaces separated by a solution containing neutralizing counter-ions. The focus is on obtaining a description where the solvent is treated explicitly rather than through a dielectric approximation as is conventionally done. We summarize the results of three papers where we have used a Stockmayer fluid model in Monte Carlo sim

The Apollonian tiling of the plane into circles is analyzed with respect to its group properties. The relevant group, which is noncompact and discrete, is found to be identical to the symmetry group of a particular geometric tree graph in hyperbolic three-space. A linear recursive method to compute the radii is obtained. Certain modifications of the problem are investigated, and relations to other

Background and aims: Radiotherapy is a valid treatment in cancer multimodal management but it is affected by severe systemic and local side effects. A murine small bowel model was used for the investigation of inflammatory features and apoptosis of local radiotherapy. Similarly the same model was used to analyze the combined effects of radiotherapy and antibiotics in the expression of matrilysin,

The last years have been characterized by tremendous institutional change in the university sector induced by far-reaching Higher Education Reforms (e.g. Bologna). Building on loose-coupling theory, we hypothesize that smaller universities were better able to adapt to the Higher Education Reforms of the recent years, triggering a decline in the optimal size of universities in the reform period. Us

What explains the gender gap in ideology, i.e. the observation that women tend to be more leftist than men? We provide new evidence showing that personality traits play a key role. Using a novel high-quality data set, we show that the mediating (i.e. indirect) effects of gender operating through personality traits by far dominate the direct effects of gender. They also dominate other potential dif

The Sustainable Development Goals (SDGs) have placed great emphasis on the need for much greater social inclusion, and on making deliberate efforts to reach marginalized groups. People with disabilities are often marginalized through their lack of access to a range of services and opportunities. Assistive products can help people overcome impairments and barriers enabling them to be active, partic

Glycogen metabolism in β-cells may affect downstream metabolic pathways controlling insulin release. We examined glycogen metabolism in human islets and in the rodent-derived INS-1 832/13 β-cells and found them to express the same isoforms of key enzymes required for glycogen metabolism. Our findings indicate that glycogenesis is insulin-independent but influenced by extracellular glucose concentr

Part of a wider project on how the Vietnam War (1945-1975) is remembered by three key collectives, Vietnamese communists, Vietnamese Americans and the United States, this article focuses primarily on the latter. Using the theory of cultural trauma as its framework, this is a study in trauma and collective memory, its impact and the social processes through which such memory is constructed and main

This book probes the relationship between Martin Heidegger and theology in light of the discovery of his Black Notebooks, which reveal that his privately held Antisemitism and anti-Christian sentiments were profoundly intertwined with his philosophical ideas. Heidegger himself was deeply influenced by both Catholic and Protestant theology. This prompts the question as to what extent Christian anti

What is required for several agents to intentionally φ together? I argue that each of them must believe or assume that their φ-ing is a single end that each intends to contribute to. Various analogies between intentional singular action and intentional joint action show that this doxastic single end condition captures a feature at the very heart of the phenomenon of intentional joint action.
