A series of studies, principally from the Mayo Clinic, have indicated that patients with an abnormal free kappa to free lambda ratio have an increased risk of progression to active myeloma from precursor conditions including monoclonal gammopathy of undetermined significance (MGUS), [32] [33] smouldering myeloma [34] and solitary plasmacytoma ...
For the special case of correlation matrices, we know that = and = /.This bounds the probability mass over the interval defined by = (). Since this distribution describes the spectrum of random matrices with mean 0, the eigenvalues of correlation matrices that fall inside of the aforementioned interval could be considered spurious or noise.
In practice, this is inferred by the detection of only one of the mutually exclusive antibody light chains, kappa or lambda, on the entire population of the abnormal B cells. Normal B lymphocytes consist of a stew of different antibody-producing cells, resulting in a mixture of both kappa- and lambda-expressing cells.
In medicine neutrophil to lymphocyte ratio (NLR) is used to show there is inflammation in the body. It is calculated by dividing the number of neutrophils by number of lymphocytes , usually from peripheral blood sample , [ 2 ] but sometimes also from cells that infiltrate tissue, such as tumor . [ 3 ]
IMAX is a proprietary system of high-resolution cameras, film formats, film projectors, and theaters known for having very large screens with a tall aspect ratio (approximately either 1.43:1 or 1.90:1) and steep stadium seating, with the 1.43:1 ratio format being available only in few selected locations.
Trouton's ratio is the ratio of extensional viscosity to shear viscosity. For a Newtonian fluid, the Trouton ratio is 3. [21] [22] Shear-thinning liquids are very commonly, but misleadingly, described as thixotropic. [23] Viscosity may also depend on the fluid's physical state (temperature and pressure) and other, external, factors.
A 95% confidence level does not mean that 95% of the sample data lie within the confidence interval. A 95% confidence level does not mean that there is a 95% probability of the parameter estimate from a repeat of the experiment falling within the confidence interval computed from a given experiment. [25]
To define the variance function for exponential dispersion models we make use of the mean value mapping, the relationship between the canonical parameter θ and the mean μ. It is defined by the function τ ( θ ) = κ ′ ( θ ) = μ . {\displaystyle \tau (\theta )=\kappa ^{\prime }(\theta )=\mu .} with cumulative function κ ( θ ...
