Using a visual search task, the present study investigated preattentive and focal attentional processes in schizophrenic patients. The performance of 15 schizophrenic patients and 20 normal subjectsâ€¦ (More)

Rational solutions for the PainlevÃ© IV equation are investigated by Hirota bilinear formalism. It is shown that the solutions in one hierarchy are expressed by 3-reduced Schur functions, and those inâ€¦ (More)

Two types of determinant representations of the rational solutions for the PainlevÃ© II equation are discussed by using the bilinear formalism. One of them is a representation by the Devismeâ€¦ (More)

A Ï„ function formalism for Sakaiâ€™s elliptic PainlevÃ© equation is presented. This establishes the equivalence between the two formulations by Sakai and by Ohta-Ramani-Grammaticos. We also give aâ€¦ (More)

The restricted solid-on-solid models in the anti-ferromagnetic regime is studied in the framework of quantum affine algebras. Following the line developed recently for vertex models, a representationâ€¦ (More)

This paper proposes a method of discrete time servo systems design and on-line management of reference signals so as not to violate state and control constraints. The stabilizing and referenceâ€¦ (More)

Two discretizations of the vector nonlinear SchrÃ¶dinger (NLS) equation are studied. One of these discretizations, referred to as the symmetric system, is a natural vector extension of the scalarâ€¦ (More)

It is well-known that the continuous PainlevÃ© equations P J (J=II, . . .,VI) admit particular solutions expressible in terms of various hypergeometric functions. The coalescenc e cascade ofâ€¦ (More)

The list ofq-PainlevÃ© equations we are going to investigate is given in section 3 below. We remark that these q-PainlevÃ© equations were discovered through various approaches to di crete PainlevÃ©â€¦ (More)

In the works [1, 3, 4, 5, 6, 7, 8, 18], the determinant formulas for the Ï„ functions of the PainlevÃ© equations are obtained. These determinant formulas arise as a consequence of the Toda equationâ€¦ (More)
