The evolution of Earth's climate on geological timescales is largely driven by variations in the magnitude of total solar irradiance (TSI) and changes in the greenhouse gas content of the atmosphere. Here we show that the slow ∼50 Wm-2 increase in TSI over the last ∼420 million years (an increase of ∼9 Wm-2 of radiative forcing) was almost completely negated by a long-term decline in atmospheri...
We report numerical observation of two new forms of stable localized solutions of the quintic complex Ginzburg-Landau equation. The 6rst form is a stationary zero-velocity solution, which consists of two motionless fronts and a source between them. We call this structure the "composite" pulse. We show that in some range of parameters, a composite pulse can coexist with a plain pulse solution. A...
A growing number of X-ray sources based on the free-electron laser (XFEL) principle are presently under construction or have recently started operation. The intense, ultrashort pulses of these sources will enable new insights in many different fields of science. A key problem is to provide x-ray optical elements capable of collecting the largest possible fraction of the radiation and to focus i...
BACKGROUND Medical competence is a central concept in medical education. Educational efforts in medical training are directed at the achievement of a maximal medical competence. The concept of the structure of medical competence (multidimensional or one-dimensional with strongly interrelated competences) therefore affects the educational developments and assessment procedures. PURPOSE To exam...
Background: Acute appendicitis is the most common surgical emergency of the childhood. Its diagnosis is really challenging. A constellation of through history taking, physical examination, radiographic investigations, and laboratory analysis should be used to balance the risk of delayed operative intervention against the removal of a normal appendix. Here a case with misdiagnosis of acute app...
Controlling spatiotemporal chaos in excitable media by applying low-amplitude perturbations locally is of immediate applicability, e.g., in treating ventricular fibrillation, a fatal disturbance in the normal rhythmic functioning of the heart. We look at a mechanism of control by the local application of a series of biphasic pulses, i.e., involving both positive and negative stimulation. This r...
The dual systems model posits that adolescent risk-taking results from an imbalance between a cognitive control system and an incentive processing system. Researchers interested in understanding the development of adolescent risk-taking use a diverse array of behavioral and self-report measures to index cognitive control and incentive processing. It is currently unclear whether different measur...
