While K-ras is essential for mouse development, expression of the K-ras 4A splice variant is dispensable [PDF]
, 2003 In mammals, the three classical ras genes encode four highly homologous proteins, N-Ras, H-Ras, and the isoforms K-Ras 4A and 4B. Previous studies have shown that K-ras is essential for mouse development and that while K-ras 4A and 4B are expressed ...

K-functionals for Besov spaces
Journal of Approximation Theory, 1991 Let \(X_ 0\), \(X_ 1\) be a pair of quasi-normed spaces, which are continuously embedded in a Hausdorff space \(X\); their \(K\)-functional, defined for all \(f\in X_ 0+X_ 1\) is \[ K(f,t):=\inf_{f=f_ 0+f_ 1}(\| f_ 0\|_{X_ 0}+t\| f_ 1\| _{X_ 1}). \] In particular, these functionals provide some information about interpolation spaces generated by \(X_ 0\

On the K functional between L1 and L2 and some other K functionals
Journal of Approximation Theory, 1986 An explicit formula for the K-functional between \(L^ 1\) and \(L^ 2\) is given. It was suggested by and contains as a special case the Valiron- Landau lemma in function theory [see \textit{P. Duren}, Univalent functions (1983; Zbl 0514.30001), pp. 104-105]. (The preface contains also an anecdote about G.

Clustering dichotomously scored items through functional k-means algorithm
, 2016 In the educational field, it is common to analyze the probability of a correct response to a test item as a continuous function of the item parameters and the subject ability. This relation is given by the item response function.

Functional effects of KCNQ K+ channels in airway smooth muscle
Frontiers in Physiology, 2013 KCNQ (Kv7) channels underlie a voltage-gated K+ current best known for control of neuronal excitability, and its inhibition by Gq/11-coupled, muscarinic signaling. Studies have indicated expression of KCNQ channels in airway smooth muscle (ASM), a tissue

Functional Mechanism of Ginsenoside Compound K on Tumor Growth and Metastasis
Integrative Cancer Therapies, 2022 Ginsenosides, as the most important constituents of ginseng, have been extensively investigated in cancer chemoprevention and therapeutics. Among the ginsenosides, Compound K (CK), a rare protopanaxadiol type of ginsenoside, has been most broadly used ...

Nearly (k, s)-Fibonacci functional equations in beta-normed spaces
, 2012 In this paper, we solve the (k, s)-Fibonacci functional equationf(k,s)(x) = kf(k,s)(x - 1) + sf(k,s) (x - 2).Moreover, we prove the Hyers-Ulam stability of the (k, s)-Fibonacci functional equation in beta-normed ...
