A Novel Necessary and Sufficient Condition for the Positivity of a Binary Quartic Form by Yang Guo

“…In this paper, by considering the common points of two conics instead of the roots of the binary quartic form, we propose a novel necessary and sufficient condition for the positivity of a binary quartic form using the theory of the pencil of conics. First, we show the degenerate members of the pencil of conics according to the distinct natures of the common points of two base conics. …”

Using Platelet-Rich Fibrin to Remove Graphite Tattoos May Yield Excellent Long-Term Result by Young Joon Cho, Yong Tak Jeong, Tae Hee Lee, Hyun Woo Cho

“…Graphite tattoos are rarely reported because they are mainly caused by an accidental injury or habits during childhood that cause a pencil to penetrate the oral mucosa. Unlike other pigmentations, it stains layers that are deeper than the subepithelial and mucosal layers, and in most cases, it takes the form of a grayish black macule. …”

Galaxy Evolution in a Pilot Survey up to z=1 and CDM Halos by E. Giraud, J. Melnick, Q.-S. Gu, H. Quintana, F. Selman, I. Toledo, P. Zelaya

“…We study spectral evolution of galaxies in a magnitude limited sample of 550 galaxies from z=1 down to z=0.3 on a pencil beam of ≈10′×10′. We concentrate on the large apparent cosmological structures along the line of sight, and we bin our individual galaxy spectra to obtain representative high S/N spectra based upon these structures. …”
