Mesh quality is critical to the accuracy and efficiency of finite element calculations, mesh smoothing an essential means reducing number poor elements improving quality. The deep Q-network-based optimization algorithm for planar Delaunay (unconstrained DQN) has attracted increasing attention due its advantages in autonomous optimization. However, unconstrained DQN model does not constrain move...

The trajectory deflection and gravitational-electromagnetic dual lensing (GEL) of charged signal in general static spherically symmetric spacetimes are considered this work. We showed that the perturbative approach previously developed for neutral particles can be extended to electromagnetic interaction case. angle still takes a (quasi-)series form finite distance effect both source observer ta...

For a given subspace, the q-Rayleigh-Ritz method projects the large quadratic eigenvalue problem (QEP) onto it and produces a small sized dense QEP. Similar to the Rayleigh-Ritz method for the linear eigenvalue problem, the q-Rayleigh-Ritz method defines the q-Ritz values and the q-Ritz vectors of the QEP with respect to the projection subspace. We analyze the convergence of the method when the...

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 ~...

Exact expressions of the Pauli exclusion operator Q in the nuclear matter calculation are presented. Exact formulae are given for the calculations of the single-particle-potential energy and the binding energy per nucleon with the exact Q operator. Numerical calculations of the G matrix in the lowest-order Brueckner theory are carried out to check the reliability of the standard angle-average a...

We report Fano resonances in a multimode square glass micropillar resonator; the resonances were obtained by using angle-resolved prism coupling. Our experiments reveal characteristically asymmetric line shapes of high-Q resonances and of detuned low-Q resonances in multimode reflection spectra. The asymmetric resonance line shapes evolve for an approximately pi phase within a 0.5 degree range ...

OBJECTIVE: To find out the quadriceps femoris angle (Q-angle) values of elite and non-elite athletes in Olympic style weightlifting. METHODS: This study included 22 male that won medals international weightlifting championships who national championships. A goniometer was used to determine muscle while were supine position inactivated. Anthropometric measurements right-left thigh lower leg leng...

We report small angle neutron scattering (SANS) from dilute suspensions of purified individual single wall carbon nanotubes (SWNTs) in D2O with added sodium dodecylbenzene sulfonate (NaDDBS) ionic surfactant. The scattered intensity scales as Q-1 for scattered wave vector, Q, in the range 0.005 < Q < 0.02 Å-1. The Q-1 behavior is characteristic of isolated rigid rods. A crossover of the scatter...
