Vortices in nonlocal Gross-Pitaevskii equation

We consider vortices in the nonlocal two-dimensional Gross-Pitaevskii equation with the interaction potential having Lorentz-shaped dependence on the relative momentum. It is shown that in the Fourier series expansion with respect to the polar angle, the unstable modes of the axial n-fold vortex have orbital numbers l satisfying 0 < \l\ < 2\n\, as in the local model. Numerical simulations show that nonlocality slightly decreases the threshold rotation frequency above which the nonvortex state ceases to be the global energy minimum and decreases the frequency of the anomalous mode of the 1-vortex. In the case of higher axial vortices, nonlocality leads to instability against splitting with the creation of antivortices and gives rise to additional anomalous modes with higher orbital numbers. Despite new instability channels with the creation of antivortices, for a stationary solution comprised of vortices and antivortices there always exists another vortex solution, composed solely of vortices, with the same total vorticity but with a lower energy.

Controlling collapse in Bose-Einstein condensates by temporal modulation of the scattering length

A study was conducted on the dynamics of 2D and 3D Bose-Einstein condensates in the case when the scattering length in the Gross-Pitaevskii (GP) equation which contains constant (dc) and time-variable (ac) parts. Using the variational approximation (VA), simulating the GP equation directly, and applying the averaging procedure to the GP equation without the use of the VA, it was demonstrated that the ac component of the nonlinearity makes it possible to maintain the condensate in a stable self-confined state without external traps.

Último Desejo e Testamento de Wilhelm Reich

O objetivo desta tradução é contribuir para a divulgação do pensamento do médico psiquiatra e inicialmente, psicanalista, Wilhelm Reich. Nascido em 24 de março de 1897, em parte da Galícia pertencente ao Império austro-húngaro, Reich morreu na prisão em 03 de novembro de 1957 nos Estados Unidos da América. Contudo, poucos meses antes do ataque cardíaco que o levou à morte, Reich legou sua obra às crianças do futuro em testamento assinado em 08 de março de 1957, onde registrou seus últimos desejos sob o testemunho de Willian Moise, Michael Silvert e Willian Steig, temendo possíveis distorções, difamações, adulterações e destruição de seus escritos após a sua morte.

Detecção molecular do rearranjo Line-1 /c-Myc em tumores venéreos transmissíveis caninos espôntaneos

Transmissible venereal tumor (TVT) is a neoplasia that develops naturally in dogs. It can be easily transplanted, which demonstrates its ability to spread from animal to animal. Since the Linr-1/c-MYC rearrangement in TVT cells had not been studied at the Veterinary Hospital of the Veterinary School, Unesp in Botucatu, SP, this study aimed to detect this genetic alteration specific to this kind of tumor by means of the polymerase chain reaction (PCR). Twenty dogs with cytological diagnosis of TVT were used. Samples of neoplastic cells were collected to determine the presence of the Line-1/c-MYC marker. The rearrangement characterized by 340bp amplicons did not vary, in agreement with previous studies using the same methodology. This contributed to a more precise identification of persistent tumor cells in cases in which gross or microscopical detection was not possible.

Quantitative comparison of mobility and gross motor function in Brazilian children with cerebral palsy

Background: Cerebral palsy (CP) presents changes in posture and movement as a core characteristic, which requires therapeutic monitoring during the habilitation or rehabilitation of children. Besides clinical treatment, it is fundamental that professionals use systems of evaluation to quantify the difficulties presented to the individual and assist in the organization of a therapeutic program. The aim of this study was to quantitatively verify the performance of children with spastic di-paresia type CP.Methods: The Pediatric Evaluation of Disability Inventory (PEDI) and Gross Motor Function Classification System (GMFM) tests were used and classification made through the GMFCS in the assessment of 7 patients with CP, 4 females and 3 males, average age of 9 years old.Results: According to GMFCS scales, 17% (n=1) were level II and 83% (n=6) were level III. The PEDI test and 88 GMFM items were used in the area of mobility. We observed that there was high correlation between mobility and gross motor function with Pearson's correlation coefficient =0.929) showing the likely impact of these areas in the functional skills and the quality of life of these patients.Conclusion: We suggest the impact of the limitation of the areas in functional skills and quality of life of these patients.

Relaxation algorithm to hyperbolic states in Gross-Pitaevskii equation

A new version of the relaxation algorithm is proposed in order to obtain the stationary ground-state solutions of nonlinear Schrodinger-type equations, including the hyperbolic solutions. In a first example, the method is applied to the three-dimensional Gross-Pitaevskii equation, describing a condensed atomic system with attractive two-body interaction in a non-symmetrical trap, to obtain results for the unstable branch. Next, the approach is also shown to be very reliable and easy to be implemented in a non-symmetrical case that we have bifurcation, with nonlinear cubic and quintic terms. (c) 2006 Elsevier B.V.
