    Antiferromagnetic order in MnO spherical nanoparticles (2011)
    American Physical Society (APS)

    Publication Date: 2011-06-16
    Description: Author(s): C. H. Wang, S. N. Baker, M. D. Lumsden, S. E. Nagler, W. T. Heller, G. A. Baker, P. D. Deen, L. M. D. Cranswick, Y. Su, and A. D. Christianson We have performed unpolarized and polarized neutron diffraction experiments on monodisperse 8- and 13-nm antiferromagnetic MnO nanoparticles. For the 8-nm sample, the antiferromagnetic transition temperature T N (114 K) is suppressed compared to that in the bulk material (119 K), while for the 13-nm ... [Phys. Rev.

    Ancestry of motor innervation to pectoral fin and forelimb (2010)

    Description: © Macmillan Publishers Limited, 2010. This article is distributed under the terms of the Creative Commons Attribution-NonCommercial-No Derivative Works 3.0 Unported License. The definitive version was published in Nature Communications 1 (2010): 49, doi:10.1038/ncomms1045.
    Description: Motor innervation to the tetrapod forelimb and fish pectoral fin is assumed to share a conserved spinal cord origin, despite major structural and functional innovations of the appendage during the vertebrate water-to-land transition. In this paper, we present anatomical and embryological evidence showing that pectoral motoneurons also originate in the hindbrain among ray-finned fish. New and previous data for lobe-finned fish, a group that includes tetrapods, and more basal cartilaginous fish showed pectoral innervation that was consistent with a hindbrain-spinal origin of motoneurons. Together, these findings support a hindbrain–spinal phenotype as the ancestral vertebrate condition that originated as a postural adaptation for pectoral control of head orientation. A phylogenetic analysis indicated that Hox gene modules were shared in fish and tetrapod pectoral systems. We propose that evolutionary shifts in Hox gene expression along the body axis provided a transcriptional mechanism allowing eventual decoupling of pectoral motoneurons from the hindbrain much like their target appendage gained independence from the head.

    Notes: [Auszug] IN reply to Prof. Brauner's criticism (NATURE, Mar. 5, p. 348, and April 9, p. 526) of our determination of the atomic weight of silver (J.C.S., 1926, 128, 2510), we have now investigated the volatility of silver and have most emphatically confirmed our original statement that no silver could ...

    Notes: [Auszug] IN a letter to NATURE of Jan. 16, 1926, p. 83, Dr. F. C. Toy criticised the use of calibration curves in photographic spectro-photometry: but the grounds for his objections were rather the difficulties in the way of adequate calibration than any quarrel with the main assumption involved, ...

    Notes: [Auszug] IN looking at a near object, the eyes are turned inwards. Therefore to procure a really natural stereoscopic view of two photographs of a near object, the eyes should be turned inwards at the same angle. To achieve this, the two photographs should be mounted in such a way that the corresponding ...
