Position statement on genuine physiotherapy research at German university hospitals.

In addition to patient care, physiotherapy is increasingly important in research at university hospitals. Genuine physiotherapy research plays a decisive role in this. This position statement describes the opportunities, benefits, framework conditions, challenges, and research priorities of genuine physiotherapy research at German university hospitals.

Modeling of light-emitting diode wavefronts for the optimization of transmission holograms.

The objective of applying transmission holograms in automotive headlamp systems requires the adaptation of holograms to divergent and polychromatic light sources like light-emitting diodes (LEDs). In this paper, four different options to describe the scalar light waves emitted by a typical automotive LED are regarded. This includes a new approach to determine the LED's wavefront from interferometric measurements.

Glucocorticoid-endocannabinoid interaction in cardiac surgical patients: relationship to early cognitive dysfunction and late depression.

Background: Endocannabinoids (ECs) are rapidly acting immune-modulatory lipid-signaling molecules that are important for adaptation to stressful and aversive situations.They are known to interact with glucocorticoids and other stress-responsive systems. Maladaptation to acute or chronic stress represents a major risk factor for the development of psychiatric disorders.
