Dynamic absorber for self-excred system with distributed parameters (vibrating string)
The dynamic absorber may be used to damp the self - excited vibration or the string. The friction mechanism of absorber (λ) has decisive influence on the amplitude of self-exerted vibration of the string. For the strong dynamic absorber the increasing

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...
