    Extended integer tent maps and dynamic hash function by LIU Jian-dong

    Published 2010-01-01
    “…Based on the analysis of uniform distribution property of the extended integer tent maps,a novel dynamic hash function with the output length of 160bit was constructed.In addition,the MD structure was improved so that the capacity of collision resistance of the middle iteration process of the hash function was enhanced without extending intermediate states.Preliminary security testing indicates that,this hash function has a high degree of security,and it can be realized easily with great rapidity.The algorithm of hash function is an ideal subsititution for traditional hash function.…”

    Cryptological properties of multi-output rotation symmetric functions by YUAN Yan-bin, ZHAO Ya-qun

    Published 2009-01-01
    “…The notion of multi-output rotation symmetric functions was introduced.Firstly, the properties of generalized Walsh spectrum and the generalized autocorrelation functions were presented.Then by constructing matrixes, some necessary and sufficient conditions were given for this class of functions to satisfying cryptological properties of balancedness, correlation immunity and so on.Especially, it presented a necessary and sufficient condition to fulfilling 1st order correlation immunity.At last, when n was odd number, the matrixes of n variables multi-output Plateaued rotation symmetric functions had special properties, so a method was introduced to find the odd number variables multi-output Plateated rotation symmetric functions.And this method only need calculate part of the generalized Walsh cycle spectrum, and the calculation could be reduced by almost half of the amount.…”

    On Symmetrical Sonin Kernels in Terms of Hypergeometric-Type Functions by Yuri Luchko

    Published 2024-12-01
    “…Moreover, for the first time in the literature, a class of Sonin kernels in terms of the convolution series, which are a far-reaching generalization of the power series, is constructed. The new symmetrical Sonin kernels derived in the paper are represented in terms of the Wright function and the new special functions of the hypergeometric type that are extensions of the corresponding Horn functions in two variables.…”

    Improving student understanding of fermionic and bosonic wave function by Christof Keebaugh, Emily Marshman, Chandralekha Singh

    Published 2025-03-01
    “…We discuss how explicit scaffolding is designed via guided teaching-learning sequences for two- or three-particle bosonic and fermionic systems to help students develop intuition about how to construct completely symmetric and antisymmetric wave function, both when spin part of the wave function is ignored and when both spatial and spin degrees of freedom are included.…”

    Functional Promiscuity of Homologues of the Bacterial ArsA ATPases by Rostislav Castillo, Milton H. Saier

    Published 2010-01-01
    “…In addition, eukaryotic ArsA homologues have several recognized functions unrelated to arsenic resistance. By aligning ArsA homologues, constructing phylogenetic trees, examining ArsA encoding operons, and estimating the probable coevolution of these homologues with putative transporters and auxiliary proteins unrelated to ArsB, we provide evidence for new functions for ArsA homologues. …”

    Differential lipid dependence of the function of bacterial sodium channels. by Nazzareno D'Avanzo, Emily C McCusker, Andrew M Powl, Andrew J Miles, Colin G Nichols, B A Wallace

    Published 2013-01-01
    “…To investigate the molecular bases of these differences we used synchrotron radiation circular dichroism spectroscopy to compare structures in liposomes of different composition, and molecular modeling and electrostatics calculations to rationalize the functional differences seen. We then examined pore-only constructs (with voltage sensor subdomains removed) and found that in these channels the lipid specificity was drastically reduced, suggesting that the specific lipid influences on voltage-gated sodium channels arise primarily from their abilities to interact with the voltage-sensing subdomains.…”
