AbstractSETI from space is currently envisaged in three ways: i) by large space antennas orbiting the Earth that could be used for both VLBI and SETI (VSOP and RadioAstron missions), ii) by a radiotelescope inside the Saha far side Moon crater and an Earth-link antenna on the Mare Smythii near side plain. Such SETIMOON mission would require no astronaut work since a Tether, deployed in Moon orbit until the two antennas landed softly, would also be the cable connecting them. Alternatively, a data relay satellite orbiting the Earth-Moon Lagrangian pointL2would avoid the Earthlink antenna, iii) by a large space antenna put at the foci of the Sun gravitational lens: 1) for electromagnetic waves, the minimal focal distance is 550 Astronomical Units (AU) or 14 times beyond Pluto. One could use the huge radio magnifications of sources aligned to the Sun and spacecraft; 2) for gravitational waves and neutrinos, the focus lies between 22.45 and 29.59 AU (Uranus and Neptune orbits), with a flight time of less than 30 years. Two new space missions, of SETI interest if ET’s use neutrinos for communications, are proposed.

We discuss the possibility of using static magnetic traps as an alternative to electrostatic traps for forming and confining structures of charged dust particles in a gas discharge plasma in the context of our study of strongly interacting Coulomb systems. Some advantages of confining structures in magnetic traps over electrostatic ones are shown. Also we provide a review of the related researches carried out first in laboratory conditions, and then under microgravity conditions including the motivation of performing the experiments aboard the International Space Station (ISS). The preparations of a new space experiment «Coulomb-magnet» as well as the differences of a new equipment from previously used are described. We proposed the main tasks of the new experiment as a study of the dynamics and structure of active monodisperse and polydisperse macroparticles in an inhomogeneous magnetic field under microgravity conditions, including phase transitions and the evolution of such systems in the kinetic heating of dust particles by laser radiation. Key words: Coulomb structures, magnetic trap, antiprobotron, diamagnetic particles, dust particles, microgravity.

Latinx writers cross boundaries between languages, renovating the experience both of language and of literature. This article takes up the invitations of several creative/disruptive artists: Víctor Hernández Cruz, Guillermo Cabrera Infante, Ana Lydia Vega, William Carlos Williams, Gloria Anzaldúa, and Tino Villanueva. The analysis shows how bilingualism transforms rhetorical figures and affective structures, arguing that metonymy—understood as contiguity and as desire—is a predominant figure of bilingualism: a figure of almost arbitrary coincidence, an unintended intimacy that writers exploit. Through rhetorical and affective gestures, bilingualism alters genre conventions and opens a new space for aesthetic pleasure and political discussion, which requires and forms an alert audience with new ways of reading. The essay traces the visions of future (and its fantasies) and of past (and its memories) from the perspective of bilingualism, showing how operating between languages allows for new ways of constructing knowledge.

Abstract Tracing the transformations phenomenological thought underwent in the sphere of literary studies after the 1930s, the paper outlines the epistemological potential of this tradition in regards to a proper understanding of the phenomenon ›text‹. Proceeding from reflections on the agonal relation between structuralistic and phenomenological traditions within contemporary literary theory, the article focuses on Husserl’s apprehension of texts as being »objects in procedure« by exploring the impact of this idea on the literary theories of Ingarden, Wellek, and Iser. In light of the - largely forgotten - fact that Karl Bühler’s pioneering Language Theory (1934) is mainly based on phenomenological thinking, the paper finally discusses to what extend Bühler’s idea of verbal expressions figuring as effective events could open a new space for the development of a literary theory of texts within recent debates on the »media of literature«.
