Section II presents the empirical results of this study. While the underlying econometric model follows the standard ‘new growth’ literature procedure of regression analysis in a cross-section of countries, it goes beyond the existing studies in drawing on a data set including proxies for technical progress and educational attainment as well as devoting special attention to different levels of ...

Previous proxy signature schemes enable a principal to have a trusted proxy agent sign messages on its behalf. We present a proxy signature scheme that combines the functionality of proxy signing and en-cryption. This proxy-signcryption scheme is useful for applications that are based on unreliable datagram style network communication model where messages are individually signed and not seriall...

In a proxy signature scheme, a potential signer delegates his capabilities to a proxy signer, who can sign documents on behalf of him. The recipient of the signature verifies both identities: that of the delegator and that of the proxy signer. There are many proposals of proxy signature schemes, but security of them has not been considered in a formal way until the appearance of [2, 8]. If the ...

Proxy-SU(3) symmetry is an approximation scheme extending the Elliott SU(3) algebra of sd shell to heavier shells. When introduced in 2017, had been justified by calculations carried out within Nilsson model. Recently our group managed map cartesian basis model onto spherical basis, proving that proxy-SU(3) corresponds replacement intruder orbitals their de Shalit-Goldhaber partners, paving way...
