Lepton asymmetry in the primordial gravitational wave spectrum [PDF]

, 2006
Effects of neutrino free streaming is evaluated on the primordial spectrum of gravitational radiation taking both neutrino chemical potential and masses into account. The former or the lepton asymmetry induces two competitive effects, namely, to increase

Steady electrodiffusion in hydrogel-colloid composites: macroscale properties from microscale electrokinetics

Anais da Academia Brasileira de Ciências, 2010
A rigorous microscale electrokinetic model for hydrogel-colloid composites is adopted to compute macroscale profiles of electrolyte concentration, electrostatic potential, and hydrostatic pressure across membranes that separate electrolytes with ...

Impact of baryonic streaming velocities on the formation of supermassive black holes via direct collapse

, 2014
Baryonic streaming motions produced prior to the epoch of recombination became supersonic during the cosmic dark ages. Various studies suggest that such streaming velocities change the halo statistics and also influence the formation of Population III ...

Wettability and ζ potentials of a series of methacrylate polymers and copolymers [PDF]

, 1985
Polymers and copolymers of different methacrylates were synthesized and coated on glass slides. The surfaces of the polymer films were characterized by their water contact angles and potentials using the Wilhelmy plate technique and streaming potential ...

Acoustic–Electrokinetic Coupling for Low-Frequency Energy Harvesting: A Theoretical Framework and Numerical Validation of the Acoustic Baroionic Harvester

Energies
Low-frequency acoustic fields—common in ventilation ducts, building façades, and industrial infrastructure—remain an underutilized source for ambient energy harvesting, particularly in humid environments where conventional contact-based or mechanically ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
