Europe has developed the Human Brain Project (HBP) whose main promoters are the US multinational company, International Business Machines Corp. (IBM), the Switzerland government and Dr. Henry Markram who is responsible for the project and announced publicly that the first artificial brain could be created in 2020. The presumptions indicate that due to what is utopian of the project and the security with what they affirm the objectives will be achieved, the forced and illegal human experimentation can be the secret method of Markram and his partners of the Human Brain Project. The hypotheses are reinforced by recent researches that suggest that IBM, the main organizer of the Human Brain Project, has performed illegal experiments with humans during the TrueNorth neuromorphic chip manufacturing and by the creation of learning projects in Mexico children's hospitals. The long list of illegal medical experiments and corrupt governments in Latin America that have allowed them officially, forces the doctors to be alert, research and denounce possible cruel neuroscientific experiments that are being performed in the Human Brain Project. ; Europa ha desarrollado el Proyecto Cerebro Humano (The Human Brain Project –HBP-) cuyos principales promotores son: la multinacional estadounidense International Business Machines Corp.

Las presunciones apuntan a que por lo utópico del proyecto y la seguridad con que afirman que van a lograr sus objetivos, la experimentación humana forzada e ilícita puede ser el método secreto de Markram y sus socios del Proyecto Cerebro Humano. Las hipótesis se refuerzan por recientes investigaciones que hacen pensar que IBM, la principal organizadora del Proyecto Cerebro Humano, ha realizado experimentos ilícitos con humanos en la construcción del chip neuromórfico TrueNorth y por la creación de proyectos de aprendizaje en hospitales infantiles de México. La larga lista de experimentos médicos ilícitos y gobiernos corruptos en Latinoamérica que los han permitido oficialmente, obliga a los médicos a estar alerta, investigar y denunciar posibles experimentos neurocientíficos inhumanos que se estén realizando en el Proyecto Cerebro Humano.

A dual-band quarter-wave plate based on a modified extraordinary transmission hole array is numerically analyzed and experimentally demonstrated at terahertz frequencies. To control independently orthogonal polarizations, the original square holes are connected with vertical slits and their lateral straight sides are replaced by meander lines. This smart design enables dual-band operation with unprecedented fractional bandwidths in a compact structure. Considering a flattening deviation lower than 40% of the optimum value, a fractional bandwidth of 53.8% and 3.8% is theoretically obtained (16.8% and 2.9% in the experiment) at 1 and 2.2 THz, respectively. At these two frequencies, the structure is 0.13-λ and 0.29-λ thick, respectively. Given the compactness of the whole structure and the performance obtained, this quarter-wave plate is presented as a competitive device for the terahertz band. ; This work was supported by the Spanish Government through the Consolider Engineering Metamaterials under Contract CSD2008-00066 and Contract TEC2011-28664-C02.

Electronic applications of large-area graphene films require rapid and accurate methods to map their electrical properties. Here we present the first electrical resistance tomography (ERT) measurements on large-area graphene samples, obtained with a dedicated measurement setup and reconstruction software. The outcome of an ERT measurement is a map of the graphene electrical conductivity. The same setup allows to perform van der Pauw (vdP) measurements of the average conductivity. We characterised the electrical conductivity of chemical-vapour deposited graphene samples by performing ERT, vdP and scanning terahertz time-domain spectroscopy (TDS), the last one by means of a commercial instrument. The measurement results are compared and discussed, showing the potential of ERT as an accurate and reliable technique for the electrical characterization of graphene samples. ; The work is part of the European project 'GRACE–Developing electrical characterisation methods for future graphene electronics', code 16NRM01. This project has received funding from the European Metrology Programme for Innovation and Research (EMPIR) programme co-financed by the Participating States and from the European Union's Horizon 2020 research and innovation programme.
