We construct embedded closed minimal surfaces in the round three-sphere S(1), resembling two parallel copies of the Clifford torus, joined by m small catenoidal bridges symmetrically arranged along a square lattice of points on the torus.

Identifying the precise locus of general cognitive ability (g) in the flow of information between perception and action is an important goal of differential psychology. To localize the negative correlation between g and reaction time to a specific processing stage, we administered a speeded number-comparison task to two groups differing in average g. The participants had to respond to two stimu...

second-language (l2) acquisition is generally thought to be constrained by maturational factors that circumscribe a critical period for native-like attainment. consistent with the maturational view are age effects among learners who begin l2 acquisition prior to, but not after, closure of the putative critical period. some studies indicate that native-like acquisition of a second language by le...

this essay intends to show critical abilities of m. foucault's thought. it purposes that assertion to structural and relativistic narratives of foucault's thought, and interpration of it on heidegger, prevents to see critical aspects and critical thought project of foucault. the essay argues that in regard to critical thought, and out of limits of previous critical theory, foucault, w...

in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...

We construct quasiconformal mappings in Euclidean spaces by integration of a discontinuous kernel against doubling measures with suitable decay. The differentials of mappings that arise in this way satisfy an isotropic form of the doubling condition. We prove that this isotropic doubling condition is satisfied by the distance functions of certain fractal sets. Finally, we construct an isotropic...
