On the existence of an upper critical dimension for systems within the KPZ universality class

In this work we extend the etching model to $d+1$ dimensions. This permits us to investigate its exponents behaviour on higher dimensions, to try to verify the existence of an upper critical dimension for the KPZ equations, with our results sugesting that $d=4$ is not an upper critical dimension for the etching model

Phase motion in the Z−(4430)Z^-(4430) amplitude in B0→ψ′π−K+B^0\to\psi^\prime\pi^-K^+ decay

In view of the proliferation in the number of new charmonium states, it is really important to have a experimental way to prove that an observed bump is, indeed, a real resonance. To do that, in this paper we present an alternative method to demonstrate the resonant behavior of a state. With this method, the phase variation of a generic complex amplitude can be directly revealed through interference in the Dalitz-plot region where it crosses a well established resonant state, used as a probe. We have tested the method for the $Z^-(4430)$ state by generating Monte Carlo samples for the $B^0\to \psi^\prime \pi^-K^+$ decay channel. We have shown that the proposed method gives a clear oscillation behavior, related to the phase variation associated to a real resonant state, in the case where the $Z^-(4430)$ is considered as a regular resonance with a strong phase variation. We have also discussed the possibility of using the proposed method complementary to the Argand diagram to determine the internal structure of the $Z^-(4430)$ state.Comment: 6 pages, 2 figures -- submitted to Phys.

O progresso do conhecimento e o desenvolvimento cultural em Leonardo Coimbra e Bernard Lonergan

Leonardo Coimbra y Bernard Lonergan dialogan con Lucien Lévy-Bruhl en el contexto de sus reflexiones acerca del progreso del conocimiento y del desarrollo cultural. Lonergan divide la evolución histórica de la conciencia humana en cuatro estadíos de desarrollo: sentido común indiferenciado, sentido común dififerenciado, consciencia diferenciada y consciencia histórica. Leonardo Coimbra divide el desarrollo del pensamiento humano en tres grandes periodos: razón mítica, razón formal abstracta y razón experimental. Los dos autores consideran que hay una ascensión del pensamiento del nivel prelógico de la mítica conciencia indiferenciada, a un nivel lógico de la razón conceptual y analítica y de la razón experimental científica.Leonardo Coimbra and Bernard Lonergan Dialogue with Lucien Lévy-Bruhl in the context of their reflections on the progress of knowledge and culture development. Lonergan divide the historical evolution of human consciousness into four states of development: undifferentiated common sense, common sense differentiated, differentiated consciousness and historical consciousness. In turn, Leonardo Coimbra divides the development of human thinking into three main periods: mythical reason, Formal experimental abstract reason and reason. The two authors consider that there is an advance in thinking from the pre-logic level of undifferentiated mythical consciousness to the logical level of conceptual and analytical reason and onto the level of experimental scientific reason.Leonardo Coimbra e Bernard Lonergan dialogam com Lucien Lévy-Bruhl no contexto das suas reflexões acerca do progresso do conhecimento e do desenvolvimento cultural.

Leonardo Coimbra divide o desenvolvimento do pensamento humano em três grandes períodos: razão mítica, razão formal abstrata e razão experimental. Os dois autores consideram que há uma ascensão do pensamento do nível pré-lógico da mítica consciência indiferenciada para o nível lógico da razão conceptual e analítica e da razão experimental científica.peerReviewe

A ressurreição pessoal e a espiritualização do Universo na filosofia escatológica "Del sentimiento trágico de la vida" de Miguel de Unamuno

Miguel de Unamuno cree que el final del universo será espiritual. La vida encierra un movimiento redentor que culminará en la salvación de toda la humanidad en el sentido de la apocatastase paulina de Orígenes. Esto no sólo se interrelacionan con la inmortalidad del alma en el sentido platónico, sino también con la resurrección del cuerpo en el sentido cristiano. La vida después de la muerte no consta de ninguna dilución en las conciencias de Dios sino en una relación personal con la conciencia de Dios y con todas las otras conciencias. Este futuro Paraiso consiste en la espiritualización de toda la creación en el ámbito de la garantía de la identidad individual de cada ser humano.Miguel de Unamuno believes the end of the Universe will be spiritualized. Life encloses a redemptive movement that shall culminate in the salvation of all of humanity in the apocatastasic sense heralded by Paul of Orígenes. This does not only interrelate with the immortality of the soul in the Platonic sense but also with the resurrection of the body in the Christian sense. Life beyond death does not consist of any dilution into the consciousnesses of God but instead in a personal relationship with God-Consciousness and with all the other consciousnesses. This future paradise consists of the spiritualization of all of creation within the scope of guaranteeing the individual identity of each being.Miguel de Unamuno acredita que no fim todo o Universo será espiritualizado. A vida encerra um movimento redentor, que culminará com a salvação de toda a humanidade, no sentido enunciado pela apocatástase paulina de Orígenes. Não se trata apenas da imortalidade da alma, no sentido platónico, mas sim da ressurreição do corpo, no sentido cristão. A vida para além da morte não consiste numa diluição das consciencias em Deus, mas sim numa relação pessoal com Deus-Consciência e com todas as outras consciências. O paraíso futuro consiste na espiritualização de toda a criação, em que será garantida a identidade individual de cada ser.peerReviewe

A Brazilian Spring? No, not really.

Crowds of protesters, police violence and expressions of discontent unseen for many decades—this is a good portrayal of what took place in the largest cities of Brazil during the first weeks of June 2013. The immediate reason for the wave of protests was the rise in bus fares, trains and subways in Rio de Janeiro and São Paulo. Similar increase had already happened in other cities such as Porto Alegre and Goiânia, which prompted protests since last February, but the demonstrations in São Paulo and Rio caused larger and more numerous protests to spread across the country
