In this paper the authors present two protocols for the common key establishment. The first protocol, which has two steps, assures the authentication of the common agreement key. The second one is a three-pass authenticated agreement key protocol and it contains a step for the key confirmation. The security of both protocols results from the elliptic curve discrete logarithm problem and their s...

In this work, chemical oxidation was used to polymerize conjugated polymer "Polypyrrole" at room temperature Graphene nanoparticles were added by in situ-polymerization get (PPY-GN) nano. Optical and Electrical properties studied for the nanocomposites. optical of nanocomposites UV-Vis spectroscopy wavelength range (200 -800 nm). The result showed absorption spectra normally determined that max...

A highly electrically conductive linear low-density polyethylene/graphene nanoplate composite with segregated structure (s-LLDPE/GN) was prepared by Yongmei Ma and colleagues through an environmentally friendly method. First, GN coated LLDPE granules were aqueous dispersion, gradually drying. SEM images show that has been successfully on the granule surfaces. Then, s-LLDPE/GN composites obtaine...

BACKGROUND Rift Valley fever (RVF) is an arthropod-borne viral zoonosis. Rift Valley fever virus (RVFV) is an important biological threat with the potential to spread to new susceptible areas. In addition, it is a potential biowarfare agent. METHODOLOGY/PRINCIPAL FINDINGS We developed two potential vaccines, DNA plasmids and alphavirus replicons, expressing the Gn glycoprotein of RVFV alone o...

Let gn1,n2 be the number of standard Young tableau of truncated shifted shape with n1 rows and n2 boxes in each row. By using the integral method this paper derives the recurrence relations of g3,n, gn,4 and gn,5 respectively. Specifically, gn,4 is the (2n− 1)-st Pell number.

BACKGROUND C3 glomerulonephritis (C3 GN) is a recently defined entity characterized by predominant C3 deposition in glomeruli due to abnormal activation of the alternative pathway of complement system. C3 GN has been reported to be associated with several systemic diseases. However, the association between C3 GN and multiple myeloma (MM) has not been well established. METHODS We herein descri...
