We studied the dynamics of lexical decisions by asking participants to categorize lexical and nonlexical stimuli and recording their mouse movements toward response buttons during the choice. In a previous report we revealed greater trajectory curvature and attraction to competitors for Low Frequency words and Pseudowords. This analysis did not clarify whether the trajectory curvature in the tw...

The flow of a viscous fluid along a curving pipe of fixed radius is driven by a pressure gradient. For a generally curving pipe it is the fluid flux which is constant along the pipe and so I correct fluid flow solutions of Dean (1928) and Topakoglu (1967) which assume constant pressure gradient. When the pipe is straight, the fluid adopts the parabolic velocity profile of Poiseuille flow; the s...

zones showed unstable results with an unacceptably high complication rate.1-3 This led to design of a 9.0 mm hyperopia ablation profile.4 Today, most laser manufacturers offer relatively large treatment zones for hyperopia. A 5.5 to 6.0 mm optical zone and 9.0 mm ablation zone diameter seems to be the current standard. Figure 1 shows some examples of nominal optical zone (OZ) and ablation zone ...

Here, a Finsler manifold $(M,F)$ is considered with corresponding curvature tensor, regarded as $2$-forms on the bundle of non-zero tangent vectors. Certain subspaces of the tangent spaces of $M$ determined by the curvature are introduced and called $k$-nullity foliations of the curvature operator. It is shown that if the dimension of foliation is constant, then the distribution is involutive...

In this paper energy bands and Berry curvature of graphene was studied. Desired Hamiltonian regarding the next-nearest neighbors obtained by tight binding model. By using the second quantization approach, the transformation matrix is calculated and the Hamiltonian of system is diagonalized. With this Hamiltonian, the band structure and wave function can be calculated. By using calculated wave f...

We study spreading of a droplet, with insoluble surfactant covering its capillary surface, on textured substrate. In this process, the surfactant-dependent surface tension dominates behaviors whole dynamics, particularly moving contact lines. This allows us to derive full dynamics droplets laid by surfactant: (i) lines, (ii) evolution (iii) boundary condition at lines and (iv) incompressible vi...
