Introduction Supported rhenium oxide catalysts have a wide range of catalytic applications, such as olefin metathesis, hydrodesulfurization, hydrogenation and NH3-SCR. Hence, the practical importance of rhenium oxide catalysts has resulted in extensive investigation of the surface structure of supported rhenium oxide catalysts. The molecular structure of supported rhenium oxides has been mainly...

There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(21)H(18)N(4)O(4). The substituted benzopyran portion of one of the independent mol-ecules exhibits disorder [occupancy 0.5248 (18):0.4752 (18)], which was modelled by using two sets of atomic positions and restraints on the chemically equivalent bond lengths and angles. The central, partial...

Viruses are nano-scale pathogenic particles. Understanding viral attachment is important to understand infectivity, disease transmission, and virus propagation throughout the host. A new simulation technique has been developed to study viral docking behavior Brownian Adhesive Dynamics (BRAD). BRAD couples Brownian motion algorithm with adhesive dynamic models, and incorporates the effect of vir...

We derive the scaling dimension associated with crossing bonds in the random-cluster representation of the two-dimensional Potts model by means of a mapping on the Coulomb gas. The scaling field associated with crossing bonds appears to be irrelevant on the critical as well as on the tricritical branch. The latter result stands in a remarkable contrast with the existing result for the tricritic...

Abstract: In the course of the development of modem synthetic methods in the field of asymmetric synthesis the SAMP-/RAMP-hydrazone method opens a highly diastereoand enantioselective route to a great variety of carbonyl compounds, alcohols, amines and heterocycles. In this paper recent advances in the development of biomimetic C-C bond formations, such as the synthesis of C2-symmetric ketodiol...

This paper investigates the long-term impact of price-level targeting on social welfare in an overlapping generations model in which the young save for old age by investing in productive capital and indexed and nominal government bonds. A key feature of the model is that the extent of bond indexation is determined endogenously in response to monetary policy as part of an optimal commitment Rams...

A new class of inositol phosphates containing energy-rich pyrophosphoryl residues has been characterized. D/L-1-Diphosphoinositol pentakisphosphate(s) and D/L-bis-(1,4)-diphosphoinositol tetrakisphosphate(s) are present as soluble ionic species in the cytosol of amoebae (Dictyostelium discoideum) at concentrations in the range of 0.05-0.25 mM. These compounds are rapidly metabolized in intact c...

We consider a portfolio consisting of a risk-free bond and an equity index which follows a jump diffusion process. Parameters for the inflation-adjusted return of the stock index and the risk free bond are determined by examining 89 years of data. The optimal dynamic asset allocation strategy for a long-term pre-commitment mean variance (MV) investor is determined by numerically solving a Hamil...

Mature human aorta contains a 70-kDa versican fragment, which reacts with a neoepitope antiserum to the C-terminal peptide sequence DPEAAE. This protein therefore appears to represent the G1 domain of versican V1 (G1-DPEAAE(441)), which has been generated in vivo by proteolytic cleavage at the Glu(441)-Ala(442) bond, within the sequence DPEAAE(441)-A(442)RRGQ. Because the equivalent aggrecan pr...
