The required configuration management and the necessary control of the Surface Ship Combat System elements demand that they be considered as integrated and tested in accordance with an integrated test plan utilizing an integrated test organization. The sometimes used approach of implementing a combat system test program based upon the individual combat system elements being independent, has proven to be less than satisfactory. Then is no question that some of the early testing at the unit, subsystem, and subprogram levels can be planned and conducted independent of a specific “end-item” combat System. This paper addresses the planning and implementing of combat system test with the emphases being upon the integrated phase of test and primarily the lead ship of a class. Information is presented to facilitate planning and implementing a combat system test program including use of shore facilities and integrating these activities with shipboard activities; when to form the test organization and what types of expertise are required; what are the key technical management tools; the proofing of test documentation; the need for detailed “step-by-step” procedures and traceability of the specified requirements; how to assist Ships Force; planning and stat using the conduct of the tests; integrating computerprogram and special testing into the test program; and the significance of early decisions on administrative and contractual arrangements.

This paper discusses performance enhancement in G/G/l queuing systems by segregating traffic flows with disparate characteristics into separate channels. It also presents a hybrid integration approach to lower the mean packet delay. We formulate a procedure for determining the optimal hybrid arrangement using an approximate analytical model for calculating the mean packet delay in G/G/l queues. We apply our findings to different interarrivai and service time distributions, namely, the lognormal and the Pareto distributions. We validate our analytical results with simulations.

Naïve CD8 T cells have the potential to differentiate into a spectrum of functional states during an immune response. How these developmental decisions are made and what mechanisms exist to suppress differentiation toward alternative fates remains unclear. We employed in vivo CRISPR-Cas9-based perturbation sequencing to assess the role of ~40 transcription factors (TFs) and epigenetic modulators in T cell fate decisions. Unexpectedly, we found that knockout of the TF Klf2 resulted in aberrant differentiation to exhausted-like CD8 T cells during acute infection. KLF2 was required to suppress the exhaustion-promoting TF TOX and to enable the TF TBET to drive effector differentiation. KLF2 was also necessary to maintain a polyfunctional tumor-specific progenitor state. Thus, KLF2 provides effector CD8 T cell lineage fidelity and suppresses the exhaustion program.
