We report small angle static light scattering measurements on colloidal aggregation at high monomer volun~e fractions. The structure factor S(q) exhibits a pronounced ma-ximum at a finite wave vector q, at any stage during the aggregation reaction. In the later stages the structure factor scales according to a universal law similar to that of spinodai decomposition dynamics: S(q/q , ) = q ; d ~...

The cylindrical resonator gyroscope (CRG) is a typical Coriolis vibratory gyroscope whose performance is determined by the Q factor and frequency mismatch of the cylindrical resonator. Enhancing the Q factor is crucial for improving the rate sensitivity and noise performance of the CRG. In this paper, for the first time, a monolithic cylindrical fused silica resonator with a Q factor approachin...

This paper describes the calculation of the semileptonic Kl3 decay form factors at order p of chiral perturbation theory, which is the next-to-leading order correction to the well-known p result achieved by Gasser and Leutwyler. At order p the chiral expansion contains oneand two-loop diagrams which are discussed in detail. The irreducible two-loop graphs of the sunset topology are calculated n...

The effect of excluded volume interactions on the structure of a polymer in shear flow is investigated by Brownian Dynamics simulations for chains with size 30 ≤ N ≤ 300. The main results concern the structure factor S(q) of chains of N=300 Kuhn segments, observed at a reduced shear rate β = γ̇τ = 3.2, where γ̇ is the bare shear rate and τ is the longest relaxation time of the chain. At low q, wh...

The pion form factor at very large Q2 is obtained by using a new pion wave function. It shows that when Q2 >> (1.8GeV )2 the pion form factor reaches the asymptotic limit αs(Q) Q .

Ultrahigh-Q microtoroids on a chip are applied as replication masters to demonstrate replica-molded high-Q microresonator arrays. Replica Q factors are nearly material loss limited, affirming the integrity of the replication process, and are as high as 5 x 10(6), or nearly a factor of 40 greater than previous polymer-based devices. Because the molding process is nondestructive, both the master ...

in many seismological applications, the earth is considered as a perfectly elastic, homogeneous, and isotropic body. although this assumption is approximately valid, it is known that seismic waves pass through the real earth that is anelastic, inhomogeneous and anisotropic.  we consider four processes that can reduce wave amplitude, i.e.: geometrical spreading, scattering, multi-pathing, and an...

T he small-angle scattering of xrays or neutrons from proteins in solution can provide important information about the structure of the protein and the nature of interactions or distance correlations among the protein molecules (1, 2). The former is encoded in the form factor [P(q)], and the latter in the structure factor [S(q)]. These functions are of great interest to the structural biology c...

In design of a parallel resonant induction heating system, choosing a proper capacitancefor the resonant circuit is quite important. The capacitance affects the resonant frequency, outputpower, Q-factor, heating efficiency and power factor. In this paper, the role of equivalent seriesresistance (ESR) in the choice of capacitance is significantly recognized. Optimal value of resonancecapacitor i...
