Parameter Identification of a PN-Guided Incoming Missile Using an Improved Multiple-Model Mechanism [PDF]
, 2022 An active defense against an incoming missile requires information of it, including a guidance law parameter and a first-order lateral time constant. To this end, assuming that a missile with a proportional navigation (PN) guidance law attempts to attack an aerial target with bang-bang evasive maneuvers, a parameter identification model based on the ...

CD8+ T cell memory is sustained in mice by hepatic stellate cells
Hepatology, EarlyView., 2022 HSC role in memory CD8+ T cell maintenance. Abstract Background and Aims Long‐lasting immunological memory is the ultimate goal of vaccination. Homeostatic maintenance of memory CD8+ cytotoxic T cells (MemCD8TCs) is thought to be mediated by IL‐15/IL‐15R heterodimer (15HD)‐expressing myeloid cells.
