In 1998, Bender and Boettcher found that a wide class of Hamiltonians, even though non-Hermitian, can still exhibit entirely real spectra provided that they obey parity-time requirements or PT symmetry. Here we demonstrate experimentally passive PT-symmetry breaking within the realm of optics. This phase transition leads to a loss induced optical transparency in specially designed pseudo-Hermit...

The current smallest self-contained modular robot uses a shape memory alloy, which is inherently inefficient, slow and difficult to control. We present the design, fabrication and demonstration of a module based on dielectric elastomer actuation. The module uses a pair of bowtie dielectric elastomer actuators in an agonist-antagonist configuration and is seven times smaller than previously demo...

Background: Transient neonatal hyperthyrotropinemia (TNH) occurs frequently in areas of iodine deficiency and may affect intellectual function and psychomotor performance. Design: A historical cohort study of intellectual development, psychomotor performance, urine iodine and thyroid function tests, performed in 9 years children with documented TNH at birth and control group. Subjects: Eighte...

Gestalt Therapy has been growing and developing since its arrival in the 1950's. For some authors, Gestalt-therapy is involved process of receiving phenomenology Humanistic Psychology. However, specifics institutionalized aspects studies, as disciplinarization, are barely visible Mato Grosso do Sul (MS). In this scenario, research aims to describe analyze Gestalt-Therapy's disciplinarization MS...
