Sharpening and generalizations of Shafer's inequality for the arc tangent function
In this paper, we sharpen and generalize Shafer's inequality for the arc
tangent function. From this, some known results are refined
Game-Theoretic Pricing and Selection with Fading Channels
We consider pricing and selection with fading channels in a Stackelberg game
framework. A channel server decides the channel prices and a client chooses
which channel to use based on the remote estimation quality. We prove the
existence of an optimal deterministic and Markovian policy for the client, and
show that the optimal policies of both the server and the client have threshold
structures when the time horizon is finite. Value iteration algorithm is
applied to obtain the optimal solutions for both the server and client, and
numerical simulations and examples are given to demonstrate the developed
result.Comment: 6 pages, 4 figures, accepted by the 2017 Asian Control Conferenc
The Decay Lifetime of Polarized Fermions in Flight
Based on the parity violation in Standard model, we study the dependence of
lifetime on the helicity of an initial-state fermion in weak interactions. It
is pointed out that if the initial fermions in the decays are longitudinally
polarized, then the decay lifetime of left-handed polarized fermions is
different from that of right-handed polarized fermions in flight with a same
velocity in a same inertial system.Comment: 7 pages, Late
