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)
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)

We present a performance analysis of a two-state heat engine model working with a single-mode radiation field in a cavity. The heat engine cycle consists of two adiabatic and two isoenergetic processes. Assuming the wall of the potential moves at a very slow speed, we determine the optimization region and the positive work condition of the heat engine(More)
