Abstract: Two new resonant antennas are discussed: 1) A bifilar helix with antiphase feed that radiates a \sin \theta shaped, circularly polarized pattern with the null perpendicular to the helical ...

As in the old times of the great “premieres” of aviation, taking advantage of light winds and favourable weather conditions, the first prototype of Integral E, registered F-WIAE, took off on December ...

This manuscript provides valuable information about the genesis of CPSF6 condensates due to HIV-1 infection. However, the evidence is incomplete as it is missing more functional assays. Furthermore, ...

A shark intestine-inspired design has led to valve-free pipes that ensure one-way liquid flow, reducing wear and tear ...

Take a look into the genetic code of the flu virus as researchers get closer to preventing the illness from countless ...

Kim explained that most hair simulations rely on the physics of straight rods, limiting the kind of hair textures that can be ...

Both the N- and C-terminal helices are highly amphipathic, and the burial of hydrophobic residues will induce helical structure in these amphipathic sequences. It is likely, therefore, that long ...

GCN2是一种在真核细胞中激活综合应激反应（integrated stress response， ...

While normal life must compete with a whole ecosystem, a mirror bacterium might behave like the only real thing in ...

Instead, the authors model hair strands as tight helices — shapes with three-dimensional spirals. In doing so, they were able to re-create three kinds of coiled-hair phenomena: phase locking ...
