In this paper, a novel refractive index (RI) sensor based on the soliton self-frequency shift (SSFS) in tellurite photonic crystal fiber (TPCF) is proposed. RI sensing in the mid-infrared region is achieved by detecting the wavelength shift of the soliton. By exploiting the high RI property of the t...

T lymphocytes consist of αβ and γδ T cells, which mature and differentiate from the same progenitor cells in the thymus. Cullin-RING ligases (CRLs), the largest family of ubiquitin ligases, require neddylation on the scaffold protein Cullins for their ligase activity. The role of neddylation–CRL sys...
