Blind Modulation Format Identification Using Differential Phase and Amplitude Ratio

IEEE Photonics Journal, 2019
We propose a blind digital modulation format identification (MFI) method for coherent optical fiber communication systems. Based on the evaluation of differential phase distribution ratio (DPDR) and average of amplitude ratio (AAR), a monitoring factor ${

Anisakis pegreffii impacts differentiation and function of human dendritic cells [PDF]

, 2018
Human dendritic cells (DCs) show remarkably phenotypic changes when matured in presence of helminth-derived products. These modifications frequently elicited a polarization towards Th2 cells and regulatory T cells thus contributing to immunological ...

Blind Modulation Format Identification Using the DC Component

IEEE Photonics Journal, 2019
We propose a blind modulation format identification (MFI) method based on direct-current (DC) component for coherent receivers. The DC value is affected by the distributions of received signal's modulated phase and amplitude. A monitoring factor R

In vitro culture with gemcitabine augments death receptor and NKG2D ligand expression on tumour cells [PDF]

, 2019
Much effort has been made to try to understand the relationship between chemotherapeutic treatment of cancer and the immune system. Whereas much of that focus has been on the direct effect of chemotherapy drugs on immune cells and the release of antigens
