One of the most sophisticated motor systems is the oculomotor system. Viewing objects in depth is supported by vergence eye movements which controls the inward (convergence) and outward (divergence) turning of the eyes. There are two main aims to this study. One compares converging responses (stimuli approaching the subject) to diverging responses (stimuli moving away from the subject) from 6o/...

the genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. the results revealed that the single shell weight showed higher genetic variation such as pcv% (17.20%), gcv% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. the d2 (mahalonobis? distance) statistics revealed...

For linearized Navier–Stokes equations, we consider an inverse source problem of determining a spatially varying divergence-free factor. We prove the global Lipschitz stability by interior data over time interval and velocity field at t0>0 spatial domain. The key machinery are Carleman estimates for equations operator rot.

Divergence-free discontinuous Galerkin (DG) finite element methods offer a suitable discretization for the pointwise divergence-free numerical solution of Borrvall and Petersson's model topology optimization fluids in Stokes flow [Topology flow, International Journal Numerical Methods Fluids 41 (1) (2003) 77--107]. The convergence results currently found literature only consider $H^1$-conformin...

purpose: to report and review a rare variant of duane's syndrome named synergistic divergence and its surgical results. patient and findings: a 16-year-old girl presented with left face turn and reduced vision in both eyes. best corrected vision was od: 3/10 and os: 10/10. there was severe adduction deficiency of the re with simultaneous abduction of the re in left gaze. she had xt= 35 in ...

Abstract The contributions of divergent and rotational wind components to the kinetic energy budget during a record-breaking rainstorm on 7 May 2017 over South China are examined. This warm-sector extreme precipitation caused historical maximum 382.6 mm accumulated rainfall in 3 h Pearl River Delta (PRD) regions China. Results show that there was high low-level southerly wind-speed tongue stret...

In this paper, we propose a pressure robust staggered discontinuous Galerkin method for the Stokes equations on general polygonal meshes by using piecewise constant approximations. We modify right-hand side of body force in discrete formulation exploiting divergence preserving velocity reconstruction operator, which is crux pressure-independent error estimates. The optimal convergence gradient,...

We show the velocity solutions to the convective, skew-symmetric, and rotational Galerkin finite element formulations of the Navier-Stokes equations are identical if Scott-Vogelius elements are used, and thus all three formulations will the same pointwise divergence free solution velocity. A connection is then established between the formulations for grad-div stabilized Taylor-Hood elements: un...

This paper utilizes descriptor state-space formulation for computation of energy amplification in incompressible channel flows. The dynamics of velocity and pressure fluctuations in these flows are described by a system of partial differential-algebraic equations. Typically, the evolution model is obtained by projecting the velocity fluctuations on a divergence-free subspace which eliminates pr...

We expand on a previous study of fronts in finite particle number reaction-diffusion systems in the presence of a reaction rate gradient in the direction of the front motion. We study the system via reaction-diffusion equations, using the expedient of a cutoff in the reaction rate below some critical density to capture the essential role of fluctuations in the system. For large density, the vel...
