ABSTRACT
Pulsar Timing Array experiments probe the presence of possible scalar or pseudoscalar ultralight dark matter particles through decade-long timing of an ensemble of galactic millisecond radio pulsars. With the second data release of the European Pulsar Timing Array, we focus on the most robust scenario, in which dark matter interacts only gravitationally with ordinary baryonic matter. Our results show that ultralight particles with masses 10^{-24.0} eVâ²mâ²10^{-23.3} eV cannot constitute 100% of the measured local dark matter density, but can have at most local density ρâ²0.3 GeV/cm^{3}.
ABSTRACT
If the treatment of shoulder problems is to be successful, an accurate diagnosis is required. To achieve this, it is necessary to pay attention to some peculiarities of the shoulder joint. Because of the great importance of the soft tissues in dynamic and static stabilization, bony lesions will occur late when massive dysfunction of the shoulder has maybe just occurred. Imaging techniques as CT or X-ray will not give a diagnosis in the early phases. Therefore, an exact clinical evaluation with a history and assessment of motion and special muscle testing will permit an early diagnosis.

To achieve the best results after shoulder surgery, an optimal rehabilitation program is absolutely necessary. The physiotherapist must pay attention to some basic features such as biomechanics, functional anatomy and the current findings. The schedule of rehabilitation depends on the operative technique, the possibility of reconstruction of the rotator cuff and on the load capacity of the soft tissue. The goal of shoulder rehabilitation is the recovery of painless and normal shoulder function.
