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.

Constructing Knowledge

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.

The Impact

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«.

AbstractWith the development of image recognition technology, face, body shape, and other factors have been widely used as identification labels, which provide a lot of convenience for our daily life. However, image recognition has much higher requirements for image conditions than traditional identification methods like a password. Therefore, image enhancement plays an important role in the process of image analysis for images with noise, among which the image of low-light is the top priority of our research. In this paper, a low-light image enhancement method based on the enhanced network module optimized Generative Adversarial Networks(GAN) is proposed. The proposed method first applied the enhancement network to input the image into the generator to generate a similar image in the new space, Then constructed a loss function and minimized it to train the discriminator, which is used to compare the image generated by the generator with the real image. We implemented the proposed method on two image datasets (DPED, LOL), and compared it with both the traditional image enhancement method and the deep learning approach. Experiments showed that our proposed network enhanced images have higher PNSR and SSIM, the overall perception of relatively good quality, demonstrating the effectiveness of the method in the aspect of low illumination image enhancement.

PRISMA (Probing Rotation and Interior of Stars: Microvariability and Activity) is a new space mission of the European Space Agency. PRISMA is currently in a Phase A study with 3 other competitors. PRISMA is the only ESA-only mission amongst those four and only one mission will be selected in Spring 1993 to become a real space mission.The goal of the Phase A study is to determine whether the payload of PRISMA can be accommodated on a second unit of the X-ray Multi-Mirror (XMM) bus; and whether the budget of the PRISMA mission can be kept below 265 MAU (’88 Economic conditions). The XMM mission is an approved cornerstone and is in a Phase A together with PRISMA.
