The proteins in the hinge ligaments of molluscan bivalves were subjected to chemotaxonomic studies according to their amino acid compositions. The hinge-ligament protein is a new class of structure proteins, and this is the first attempt to introduce chemical taxonomy into the systematics of bivalves. The hinge-ligament proteins from morphologically close species, namely mactra (superfamily Mac...

Host-parasite systems have been useful in understanding coevolutionary patterns in sympatric species. Based on the exceptional interaction of the long-lived and highly host-specific freshwater pearl mussel (FPM; Margaritifera margaritifera) with its much shorter-lived host fish (Salmo trutta or Salmo salar), we tested the hypotheses that a longer duration of the parasitic phase increases fitnes...

Pearl millet (Pennisetum glaucum (L.) R. Br) is a staple food in many developing countries and constitutes the major source of essential nutrients in semi-arid and arid regions of Africa and India. The knowledge about the nutrient content of autochthonous pearl millet ecotypes is scarce. In this study, biochemical analysis of six Tunisian pearl millet ecotypes has been investigated. Results pro...

A recent paper of Singal [7] argues that a uniformly accelerated particle does not radiate, in contradiction to the consensus of the research literature over the past 30 years. This note points out some questionable aspects of Singal’s argument and shows how similar calculations can lead to the opposite conclusion.

The structure of neurons and axons was studied in the medial division of the medial geniculate body of the cat with the Golgi methods. The results show that the medial division consists of morphologically heterogeneous neurons. The main types, in descending order of frequency, are medium-sized neurons with (1) radiate, (2) tufted, or (3) elongate dendrites; (4) small stellate or radiate neurons...

We present calibrated measurements of single-photon Thomson scattering from free electrons driven by a laser with intensity 1018  W/cm2. The measurements demonstrate that individual electrons radiate with the strength of point emitters, even when their wave packets spread to the scale of the driving-laser wavelength. The result agrees with predictions of quantum electrodyn...

We demonstrate that matter-wave solitary pulses formed from Bose condensed atoms moving inside optical lattices continuously radiate dispersive matter waves with prescribed momentum. Our analytical results for the radiation parameters and the soliton decay rate are found to be in excellent agreement with numerical modeling performed for experimentally relevant parameters.

Illuminated by ultrashort optical pulses, large area multiplex terahertz semiconductor emitters that work on photoDember currents and Schottky potentials radiate a directional electromagnetic terahertz pulse which is controlled by the angular spectrum of the incident optical beam. Using the lens that focuses the incident near infra-red pulse, we have demonstrated THz emission focusing in free s...
