This report presents testing of a prototype cantilevered liquid-nitrogen-cooled silicon mirror. This mirror was designed to be the first mirror for the new soft X-ray beamlines to be built as part of the Advanced Light Source Upgrade. Test activities focused on fracture, heat transfer, modal response and distortion, and indicated that the mirror functions as intended.

- Neuromorphic systems are new types of computer systems that help scientists explore and research better, but making them easy to use and efficient is tricky.
- The BrainScaleS-2 system is a special kind of neuromorphic hardware that uses unique software features to make it easier for researchers to run experiments.
- The text talks about improvements like faster training methods, new types of neurons, and better access for users, plus plans for making the hardware even bigger and easier to work with in the future.
Background: Dystonia is a movement disorder with patterned, directional, and often sustained muscle contractions that produce abnormal postures or repetitive movements. Deep brain stimulation (DBS) of the globus pallidus internus (GPi) is an effective and safe treatment for medically refractory dystonia. However, recent studies reported gait problems, gait freezing and falls in patients treated with DBS.

Patients with lesions of the prefrontal cortex as a result of frontal brain tumors (intra- and extra-axial) can show impairments of executive functions 1 2 3 4. Although there are a large number of psychological tests, the detection of impairments of relevant everyday executive functions in these patients is still extremely difficult. In 30 patients with lesions of the prefrontal cortex, the executive functions were tested with the Behavioral Assessment of Dysexecutive Syndrome (BADS) and 21 patients were also followed up postoperatively.

We evaluated conventional and dynamical measures of postural sway in Parkinson disease (PD) patients with and without freezing episodes.
Methods: COP (center of pressure) data were recorded during quiet standing with eyes open, eyes closed and while performing a dual task.
