The log-likelihood function being plotted is used in the computation of the score (the gradient of the log-likelihood) and Fisher information (the curvature of the log-likelihood). Thus, the graph has a direct interpretation in the context of maximum likelihood estimation and likelihood-ratio tests .
J1808−5104 is an ultra metal-poor (UMP) star, one that has a logarithmic metallicity [Fe/H] less than −4, or 1 / 10,000 th of the levels in the Sun. [8] It is a single-lined spectroscopic binary, with radial velocity variations in its spectral absorption lines interpreted as orbital motion of the visible star.
Negative values of the decimal logarithm of the median lethal dose LD 50 (−log 10 (LD 50)) on a linearized toxicity scale encompassing 11 orders of magnitude. Water occupies the lowest toxicity position (1) while the toxicity scale is dominated by the botulinum toxin (12).
η Cassiopeiae (Latinised to Eta Cassiopeiae) is the system's Bayer designation.The designations of the two constituents as Eta Cassiopeiae A and B derive from the convention used by the Washington Multiplicity Catalog (WMC) for star systems, and adopted by the International Astronomical Union (IAU).
HD 131664 is an 8th magnitude star in the southern constellation of Apus with an orbiting brown dwarf or stellar companion. Parallax measurements by the Gaia space observatory provide an estimated distance of 172.5 light years from the Earth.
Atmospheric concentration of HFC-23 vs. similar man-made gases (right graph), log scale. CHF 3 is a potent greenhouse gas. A ton of HFC-23 in the atmosphere has the same effect as 11,700 tons of carbon dioxide. This equivalency, also called a 100-yr global warming potential, is slightly larger at 14,800 for HFC-23. [10]
The main symptoms of a hyoid bone fracture include pain when the affected person rotates their neck, trouble swallowing (), and painful swallowing (odynophagia).Other symptoms can be crepitus or tenderness over the bone, suffocation when sticking out the tongue, dyspnea, dysphonia, and subcutaneous emphysema.
VB 10 or Van Biesbroeck's star / v æ n ˈ b iː z b r ʊ k / [7] is a small and dim red dwarf [2] located in the constellation Aquila.It is part of a binary star system. VB 10 is historically notable as it was the least luminous and least massive known star from its discovery in 1944, until 1982 when LHS 2924 was shown to be less luminous. [8]
