We present and explore a general method for deriving a Lie-Markov model from a finite semigroup. If the degree of the semigroup is k, the resulting model is a continuous-time Markov chain on k states and, as a consequence of the product rule in the semigroup, satisfies the property of multiplicative closure. This means that the product of any two probability substitution matrices taken from the...

Novel Visualization and Algebraic Techniques for Sustainable Development Through Property Integration. (December 2006) Vasiliki Kazantzi, B.S., University of Thessaloniki, Greece; M.E., Texas A&M University Chair of Advisory Committee: Dr. Mahmoud M. El-Halwagi The process industries are characterized by the significant consumption of fresh resources. This is a critical issue, which calls for a...

Many oxychalcogenide NLO materials have now been designed and synthesized through chemical substitution engineering. Herein, the crystal structures structure-property relationships of recent oxychalcogenides with IR properties are reviewed along how to integrate best features different anion groups. For more details, see Review by H. Yu et al. (DOI: 10.1002/chem.202203597).

Ethanol alters the function of several members of the Cys-loop ligand-gated ion channel superfamily. Recent studies have shown that the sensitivity of the α1 glycine receptor (GlyR) to ethanol can be affected by the state of G protein activation mediated by the interaction of Gβγ with intracellular amino acids in the GlyR. Here, we evaluated the physicochemical property of Lys385 that contribut...

The key substitution property is introduced by Blake-Wilson and Menezes [1] and formalized by Menezes and Smart [8] as attacks. The key substitution property is as follow: another person other than true signer can produce another public (and secret) key such that a message and signature pair created by the signer is valid under the public key. The research of the key substitution attacks [8, 6,...

To understand better the impact of donor-acceptor substitution on the properties of linearly π-conjugated compounds, we performed a computational study on a series of variably substituted trans-polyacetylenes, polyynes, and polythiophenes. The focus of this work is on how rapidly the impact of a given substituent or a given combination of substituents vanishes along the π-conjugated chain. The ...

Single phase, sol-gel prepared Cu1-x Fe x O (0 ≤ x ≤ 0.125) powders are characterized in terms of structural, electronic and magnetic properties. Using dielectric and magnetic studies we investigate the coupling of electron and spin. The electrical conductivities and activation energies are studied with increasing Fe content. Modelling of experimental conductivity data emphasizes a single hoppi...

Although HIV-1 Vpr displays several functions in vitro, limited information exists concerning their relevance during infection. Here, we characterized Vpr variants isolated from a rapid and a long-term non-progressor (LTNP). Interestingly, vpr alleles isolated from longitudinal samples of the LTNP revealed a dominant sequence that subsequently led to diversity similar to that observed in the pr...

Instructor: Dr. Attila A Yavuz Homework 1 (10/29/2014) ANSWER KEY 1) [8 total] (2) What is the basic design technique, which is frequently used to construct modern symmetric ciphers? Substitution Permutation Networks (SPN) (2) What are the main security properties achieved via this designed technique? Confusion by substitution and diffusion by permutation (4) Given the example of AES, which fun...

Here, we describe an improved system for protein crystallization based on heterogeneous nucleation using fluorinated layered silicate. In addition, we also investigated the mechanism of nucleation on the silicate surface. Crystallization of lysozyme using silicates with different chemical compositions indicated that fluorosilicates promoted nucleation whereas the silicates without fluorine did ...
