Range-Renewal Structure of I.I.D. Samplings
In this note the range-renewal structure of general independent and identically distributed samplings is discussed, which is a natural extension of the result in Chen et al (arXiv:1305.1829).

Single production of heavy top quark from the three-site Higgsless model
We consider single production of the heavy top quark T predicted by the three-site Higgsless model in future high energy collider experiments, such as the high energy linear e^{+}e^{-} collider (ILC), the linear-ring type $ep$ collider (THERA), and the CERN Large Hadron Collider (LHC). Our numerical results show that the possible signals of the heavy top quark T might be observed via the process $e^{+}e^{-}\to t\bar{T}\to t\bar{t}Z$ in future ILC experiments and via the subprocess $qb\to q'T$ at the LHC.

Lepton flavor violating semileptonic $τ$ decays $τ\to lP(V)$ in a topcolor scenario
The contributions of the neutral top-pion $π_{t}^{0}$ and the non-universal gauge boson $Z'$ predicted by topcolor scenario to the lepton flavor violating $(LFV)$ semileptonic $τ$ decays $τ\to lP(V)$ $(P=π^{0}, η, η' $ and $ V=ρ^{0}, ϕ)$ are discussed. We find that the contributions of $Z'$ to these decay processes are generally larger than those from $π_{t}^{0}$. $π_{t}^{0}$ can only make the value of the branching ratio $Br(τ\to lP)$ in the range of 1$\times10^{-11}$ $\sim$ 1$\times10^{-16}$, which is far below the sensitivity of foreseeable experiments. With reasonable values of the free parameters, the non-universal gauge boson $Z'$ can make the value of the branching ratio $Br(τ^{-}\to μ^{-}ϕ)$ reach 1$\times10^{-7}$, which might approach the observable threshold of near-future experiments.

Single production of charged gauge bosons from little Higgs models in association with top quark at the $LHC$
In the context of the little Higgs models, we discuss single production of the new charged gauge bosons in association with top quark at the $CERN$ Large Hadron Collider$(LHC)$. We find that the new charged gauge bosons $W_{H}^{-}$ and $X^{-}$, which are predicted by the littlest Higgs model and the SU(3) simple model, respectively, can be abundantly produced at the $LHC$. However, since the main backgrounds coming from the processes $pp\to t\bar{t}+X$ and $pp\to tW^{-}+X$ are very large, the values of the ratios $N_{W}$ and $N_{X}$ are very small in most of the parameter space. It is only possible to detect the signal of the gauge boson $W_{H}^{-}$ via the process $pp\to gb+X\to tW_{H}^{-}+X$ at the $LHC$ in a small region of the parameter space.
