This paper introduces two kinds of handover algorithms that adjust the handover (HO) parameters of LTE (Long-Term Evolution) eNodeB (evolved NodeB) to improve the overall network performance and diminish negative effects. The focus is on the impact that two kinds of handover algorithms compare to A3 event based on the optimization of hysteresis and(More)

Anti-tumour immune activation by checkpoint inhibitors leads to durable responses in a variety of cancers, but combination approaches are required to extend this benefit beyond a subset of patients. In preclinical models tumour-derived VEGF limits immune cell activity while anti-VEGF augments intra-tumoral T-cell infiltration, potentially through vascular(More)
