Verheul et al. for general access structures by expanding Naor’s scheme[2], and studied its related properties, and then presented color VCS[3].
Yi Feng et al. also proposed the color VCS for general access structure with minimal expanded pixels[4].
Hsu el at.[10] present a new authenticated scheme based on discrete logarithms, which combine the merits of digital signature scheme and verifiable secret sharing scheme.

Friendrich et al [1] pointed out that micro-milling is for 3D mini-element, which can effectively perform micro removal.
Alauddin et al [4] developed a prediction model to optimize end-milling of Inconel 718 for better surface roughness.
Wentian et al [5] constructed a model for micro-milling of aluminum to predict machined roughness.
The method was proposed by Horn et al [10] in 1994 as a pre-selection mechanism, which is described next.

According to Tong el al. [1], Taguchi method is an implemented experimental technique, used an orthogonal array to perform experiments and employed the signal-to-noise (S/N) ratio as the quality measurement index, to optimize only a single response, i.e., the parametric settings can be optimised with respect to only one performance characteristic at a time.
Sim et al. [2] had studied the variation of hardness and the thickness of WC-Co (material of cemented carbide), generated by WEDM.
Zhang et al. [3] investigated the effect of the EDM pulse current on the micro structure and the properties of the P20 specimen surface.
Ghani et al. [4] published the comparison effect of the end milling and EDM parameters on the surface integrity of AISI H13 tool steel (HRC 50±3).

The doping of Si [15], Ga [16], and Al [17] in ZnO films has been studied.
Tansley et al. [26] reported that the presence of ionized adsorbates on the crystalline surfaces could increase the intercrystalline barrier height, which decreased the effective carrier mobilities and hence the conductivities.
Morgan et al. [29] and Ghosh et al. [30] studied ITO films and ZnO films and obtained the similar results. 20 30 40 50 60 70 80 (103) (002) as-deposited annealing in N2 annealing in O2 Intensity (cps) 2£c(degree) � Fig. 1 The X-ray diffraction patterns of ZnO:Ti films before and after annealing in N2 or O2.

But, it is very difficult to find attempts of such B doping via liquid growth, except the work of Epelbaum et al.
Savidou et al [10] have shown that, under accelerated proton incidence, B undergoes mainly two nuclear reactions giving γ emission at specific energies, 429 and 718 keV respectively for 10B (p, αγ) 7Be and 10B (p, p'γ) 10B.
One can see that there is no interference with other peaks of the substrate or of other classic impurities found in such material like nitrogen or even Al.
