Species-specific regulation of XIST by the JPX/FTX orthologs

Olga Marie Louise Rosspopoff

X chromosome inactivation (XCI) is an essential process, yet it initiates with remarkable diversity in various mammalian species. XIST, the main trigger of XCI, is controlled in the mouse by an interplay of lncRNA genes (LRGs), some of which evolved concom ...

Subarray antenna fed by analog beamforming network for 5G picocell applications

Anja Skrivervik

In this paper a subarray fed by an analog beamforming network for 5G picocell applications is proposed. Design requirements are presented taking into account frequency band operation, bandwidth, radiation pattern shape and both, antenna element and transmi ...

Tunable radiator for small satellite application

Jean-Daniel Landis, Frédéric Bongard, Tomislav Debogovic, Pedro Robustillo Bayon

A tunable radiator for space application has been developed to meet stringent requirements in terms of electrical and environmental specifications but also low mass, simple manufacturing and low cost. The element is based on the folded PIFA antenna, with s ...

Turnover and accumulation of genetic diversity across large time-scale cycles of isolation and connection of populations

Séverine Vuilleumier Varisco

Major climatic and geological events but also population history (secondary contacts) have generated cycles of population isolation and connection of long and short periods. Recent empirical and theoretical studies suggest that fast evolutionary processes ...

TOLPA (Tripod Omnidirectional Low Profile Antenna): a vertically polarized antenna with 90% bandwidth

Jean-François Zürcher

A new vertically polarized omnidirectional antenna, inspired by an old design, has been studied, optimized, realized and measured. With a radiation pattern similar to the classical monopole on a ground plane, the proposed antenna concept provides a much la ...

Models and Algorithms for Whole-Genome Evolution and their Use in Phylogenetic Inference

Yu Lin

The rapid accumulation of sequenced genomes offers the chance to resolve longstanding questions about the evolutionary histories, or phylogenies, of groups of organisms. The relatively rare occurrence of large-scale evolutionary events in a whole genome, e ...

Numerical investigations of a multi-walled carbon nanotube-based multi-segmented optical antenna

Wei Wu

Motivated by the fabrication potential of multi-walled carbon nanotube structures, we numerically investigated a paired structure consisting of two metallic spheres each grown on one end of a multi-walled nanotube. The paired two-segmented structure is cap ...
