VNF and Container Placement: Recent Advances and Future Trends

CoRR, 2022
With the growing demand for openness, scalability, and granularity, mobile network function virtualization (NFV) has emerged as a key enabler for most mobile network operators. NFV decouples network functions from hardware devices. This decoupling allows network services, referred to as Virtualized Network Functions (VNFs), to be hosted on commodity ...

Complex Regulation of RETINOBLASTOMA‐RELATED's Interactions With E2Fs via Phosphorylation

Plant, Cell &Environment, EarlyView.
ABSTRACT Arabidopsis RETINOBLASTOMA‐RELATED (RBR) regulates cell proliferation by interacting with E2F transcription factors and DIMERISATION PARTNER, RB‐LIKE, E2F AND MULTI‐VULVAL CLASS B COMPLEX (DREAM) components. Although CDK‐CYCD phosphorylation is believed to affect RBR's E2F‐binding capacity, the precise phosphorylation events inhibiting RBR's ...

Coming out of the cold: Vanadium is an important player in N‐fixation in warm tropical environments

Ecology, Volume 107, Issue 4, April 2026.
Abstract Nitrogen (N)‐fixation is a crucial source of reactive N in terrestrial environments. The nitrogenase enzyme (Nase), responsible for this conversion, has three isoforms: molybdenum (Mo)‐, vanadium (V)‐, and iron (Fe)‐Nases. The Mo‐Nase is found in all N‐fixers, but the distribution pattern and drivers of V‐ and Fe‐Nases remain poorly understood.
