We show that a recently developed method for generating bounds for the discrete energy states of the non-hermitian −ix3 potential (Handy 2001) is applicable to complex rotated versions of the Hamiltonian. This has important implications for extension of the method in the analysis of resonant states, Regge poles, and general bound states in the complex plane (Bender and Boettcher (1998)).

In the 1920s Max Wertheimer enunciated a credo of Gestalt theory: the properties of any of the parts are governed by the structural laws of the whole. Intense efforts at the time to discover these laws had only very limited success. Psychology was in the grips of the Fechnerian tradition to seek exact relationships between the material and the mental and, because the Gestalt movement could not ...

The aim of this paper is to describe algebraic K3 surfaces with an even set of rational curves or of nodes. Their minimal possible Picard number is nine. We completely classify these K3 surfaces and after a carefull analysis of the divisors contained in the Picard lattice we study their projective models, giving necessary and sufficient conditions to have an even set. Moreover we investigate th...

We give a generalization of Bender's area-perimeter relation for plane lattice-point-free convex regions to simply connected regions, thus we solve a problem posed by M. Silver 10]. Further the result is used for a lattice version of the Dido problem.

iments the profile of the tangential wind for Hurricane Gloria at 1200 UTC 22 September, 1985 (just after the storm was first upgraded to a hurricane) was used as the initial condition of the hurricane. Following the procedure outlined in Bender et al., 1993, the obtained symmetric vortex was placed onto the environmental fields at 18°N, with each experiment integrated to 72h.

Through the use of participant observations and the collection of standardized psychological test scores from a sample of 56 street children, their characteristics were examined. The Kohs Block Design measured their intelligence; the Human Figure Drawing and the Bender-Gestalt tests were used to measure emotional and neurological functioning. The data indicated that their mental health was adeq...

the past and present, I am concerned about the low value placed on cultural landscapes by national and international agencies charged with promoting, protecting, and managing cultural heritage in the developing world. My research in Bolivia and Peru focuses on a particular class of unappreciated cultural landscape, the mundane, traditional agricultural landscape (Fig. 1).1 It is difficult to co...

We treat quantum chromodynamics (QCD) using a set of Dyson-Schwinger equations derived, in differential form, with the Bender-Milton-Savage technique. In this way, we are able to derive low energy limit that assumes form non-local Nambu-Jona-Lasinio model all parameters properly fixed by QCD Lagrangian and determination mass gap gluon sector.
