Role of accelerated segment switch in exons to alter targeting (ASSET) in the molecular evolution of snake venom proteins
2009-06-30

BackgroundSnake venom toxins evolve more rapidly than other proteins through accelerated changes in the protein coding regions. Previously we have shown that accelerated segment switch in exons to alter targeting (ASSET) might play an important role in its functional evolution of viperid three-finger toxins. In ...

Ectopic expression of a Meloidogyne incognita dorsal gland protein in tobacco accelerates the formation of the nematode feeding site.
2010-09-16

Meloidogyne spp., plant-parasitic nematodes present worldwide, are intensively studied because of the damage caused to a large variety of agronomically important crops. Several reports indicate that proteins from the Meloidogyne spp. dorsal gland might play an important role to allow proper establishment of a functional nematode feeding site. The precise role of these ...

The Transverse RF Accelerator.
1981-01-01

High electric fields are obviously advantageous in powerful electron accelerators: for a given energy gain per particle, the device length is inversely proportional to the maximum field; and the maximum current is roughly proportional to the field. The tr...

Laser-driven acceleration with Bessel and Gaussian beams
1997-03-01

The possibility of enhancing the energy gain in laser-driven accelerators by using Bessel laser beams is examined. Scaling laws are derived for the propagation length, acceleration gradient, and energy gain in various accelerators for both Gaussian and Bessel beam drivers. For equal beam ...

Nutrition and growth
1977-07-01

Longitudinal growth data on children who developed obesity during childhood reveal a distinct tendency for height gain to accelerate coincident with or after the onset of excessive weight gain. The magnitude of the relative height increment is related to the degree of overweight. Overnutrition accelerates growth, ...

Surfing acceleration of ions at relativistic, oblique shocks
2005-08-01

It was shown in that one of the limits to the shock surfing acceleration of ions at quasiperpendicular shocks is due to the obliqueness of the shock wave. In this paper, a critical obliqueness is found for the relativistic shock wave, below which the energy gain of the particle due to the shock surfing acceleration, is not limited by ...
