The impact of acute blood-flow-restriction resistance exercise on somatosensory-evoked potentials in healthy adults.

Blood-flow-restriction exercise (BFR) is an emerging method to stimulate hypertrophy and strength without the need for high training loads. However, the impact of BFR concerning somatosensory processing remains elusive. Here, we aimed to investigate the acute effects of BFR on somatosensory processing in healthy adults using somatosensory-evoked potentials (SEPs).

Texture-based residual stress analysis of laser powder bed fused Inconel 718 parts.

Although layer-based additive manufacturing methods such as laser powder bed fusion (PBF-LB) offer an immense geometrical freedom in design, they are typically subject to a build-up of internal stress ( thermal stress) during manufacturing. As a consequence, significant residual stress (RS) is retained in the final part as a footprint of these internal stresses. Furthermore, localized melting and solidification inherently induce columnar-type grain growth accompanied by crystallographic texture.

Reconstruction of incomplete X-ray diffraction pole figures of oligocrystalline materials using deep learning.

X-ray diffraction crystallography allows non-destructive examination of crystal structures. Furthermore, it has low requirements regarding surface preparation, especially compared to electron backscatter diffraction. However, up to now, X-ray diffraction has been highly time-consuming in standard laboratory conditions since intensities on multiple lattice planes have to be recorded by rotating and tilting.

Evaluation of extremely steep residual stress gradients based on a combined approach using laboratory-scale equipment.

Surface treatments characterized by rapid heating and cooling ( laser hardening) can induce very steep residual stress gradients in the direct vicinity of the area being treated. These gradients cannot be characterized with sufficient accuracy by means of the classical sinΨ approach applying angle-dispersive X-ray diffraction. This can be mainly attributed to limitations of the material removal method.
