SKEWNESS AND PERMUTATION [PDF]

open access: yesCladistics, 1992
Abstract— The skewness criterion of phylogenetic structure in data is too sensitive to character state frequencies, is not sensitive enough to number of characters (degree of corroboration) and relies on counts of arbitrarily‐resolved bifurcating trees. For these reasons it can give misleading results.

Familial skewed x chromosome inactivation in adrenoleukodystrophy manifesting heterozygotes from a Chinese pedigree. [PDF]

open access: yesPLoS ONE, 2013
X-linked adrenoleukodystrophy (X-ALD) is an inherited neurodegenerative disorder caused by mutations in the ABCD1 gene. Approximately 20% of X-ALD female carriers may develop neurological symptoms. Skewed X chromosome inactivation (XCI) has been proposed

Quantifying Distribution of Flow Cytometric TCR-Vβ Usage with Economic Statistics. [PDF]

open access: yesPLoS ONE, 2015
Measuring changes of the T cell receptor (TCR) repertoire is important to many fields of medicine. Flow cytometry is a popular technique to study the TCR repertoire, as it quickly provides insight into the TCR-Vβ usage among well-defined populations of T

Defect Imaging Enhancement through Optimized Shape Factors of the RAPID Algorithm Based on Guided Wave Beam Pattern Analysis

open access: yesSensors, 2021
In this study, a modified imaging algorithm was implemented to improve the imaging accuracy for defects located on a structure. Based on analysis of the Lamb wave mode, a guided ultrasonic wave inspection technique was applied, which was able to ...

All Trans Retinoic Acid, Transforming Growth Factor β and Prostaglandin E2 in Mouse Plasma Synergize with Basophil-Secreted Interleukin-4 to M2 Polarize Murine Macrophages. [PDF]

open access: yesPLoS ONE, 2016
In previous studies we found that macrophages (MФs) from SH2-containing inositol-5'-phosphatase (SHIP) deficient mice are M2 polarized while their wild type (WT) counterparts are M1 polarized and that this difference in MФ phenotype can be recapitulated ...

Circulating Tfh cell and subsets distribution are associated with low‐responsiveness to hepatitis B vaccination

open access: yesMolecular Medicine, 2021
Background An estimated 5–10 % of healthy vaccinees lack adequate antibody response following receipt of a standard three-dose hepatitis B vaccination regimen.

Constructions of skew-tolerant and skew-detecting codes [PDF]

open access: yesIEEE Transactions on Information Theory, 1993
Summary: Recently the paradigm of skew-tolerant parallel asynchronous communication was introduced, along with constructions for codes that can tolerate or detect skew. Some of these constructions were improved by the third author [Construction of \((t_ 1, t_ 2)\)-tolerant codes, Proc. Dilijan Conf; Sept. 1991].

TNO1, a TGN-localized SNARE-interacting protein, modulates root skewing in Arabidopsis thaliana

open access: yesBMC Plant Biology, 2017
Background The movement of plant roots within the soil is key to their ability to interact with the environment and maximize anchorage and nutrient acquisition.

Normal but Skewed?

open access: yes, 2021
We propose a multivariate normality test against skew normal distributions using higher-order loglikelihood derivatives which is asymptotically equivalent to the likelihood ratio but only requires estimation under the null. Numerically, it is the supremum of the univariate skewness coefficient test over all linear combinations of the variables.
