We study pattern formation in the bounded confidence model of opinion dynamics. In this random process, opinion is quantified by a single variable. Two agents may interact and reach a fair compromise, but only if their difference of opinion falls below a fixed threshold. Starting from a uniform distribution of opinions with compact support, a traveling wave forms and it propagates from the doma...

Arginine carboxypeptidase activity in human serum, measured with the hippuryl-L-arginine substrate, is about three times higher than in human plasma. This difference is much smaller when hippuryl-L-lysine is used as the substrate. When fresh serum is incubated at 30 degrees C, the arginine and lysine carboxypeptidase activity decreases until a stable activity, close to the plasma activity, is r...

We consider the spatial restricted three body problem RTBP for values of the mass parameter close to Routh We analyse the dynamics around the vertical peri odic orbits which are born at the equilateral equilibrium points L and L and we describe the con nement around the complex unstable periodic orbits due to the D stable and unstable invariant manifolds

OBJECTIVE To assess whether neopterin concentrations in women with unstable angina differ from those in women with chronic stable angina. DESIGN Prospective cohort study. SETTING University hospital in south west London. PATIENTS 114 consecutive women with angina were studied: 82 had chronic stable angina (typical exertional chest pain, positive exercise ECG testing, and/or abnormal myoca...

In this research, samples of AlMg0.7Si aluminum alloy are deformed up to three passes using equal channel angular pressing (ECAP). Formation of a sub-micron structure after three passes of ECAP is demonstrated. Microstructural stability of the samples is investigated at temperatures of 300-500 °C. At 300 °C, fine recrystallized structure forms after 10 min which remains stable when the ...

Suspension of a streptococcal L form in hypotonic solutions is accompanied by loss of viability and structural disintegration (Panos and Barkulis, 1959). Consequently, a variable amount of water soluble material is lost in employing hypotonic solutions for washing procedures and results in only a residue portion remaining. Analyses of such residues in terms of the chemical constituents of the i...

This study showed that streptococcal L forms could not be isolated from children who were either carriers of group A streptococci or had disease due to this pathogen. It was possible to induce L colony formation in 15 strains of group A. Streptococcal bacteriophages were demonstrated in 20% of group A streptococci isolated from school children who were carriers, but did not have clinical eviden...

We present examples of Maass forms on Hecke congruence groups, giving low eigenvalues on Γ0(p) for small prime p, and the first 1000 eigenvalues for Γ0(11). We also present calculations of the L-functions associated to the Maass forms and make comparisons to the predictions from random matrix theory.
