Functions of Generalized Bounded Variation [PDF]
, 2013 This thesis is devoted to the study of different generalizations of the classical conception of a function of bounded variation. First, we study the functions of bounded p-variation introduced by Wiener in 1924.

Functions of bounded variation, the derivative of the one dimensional maximal function, and applications to inequalities [PDF]
, 2007 We prove that if f: I ⊂ ℝ → ℝ is of bounded variation, then the uncentered maximal function M f is absolutely continuous, and its derivative satisfies the sharp inequality ∥DMf∥ L1(I) ≤ ∥Df∥(I).

On functions of bounded n-th variation [PDF]
Fundamenta Mathematicae, 1988 Following an idea of \textit{W. L. C. Sargent} [Proc. Lond. Math. Soc., II. Ser. 47, 212-247 (1941; Zbl 0061.102); ibid. 52, 365-376 (1951; Zbl 0045.332)], the authors introduce concepts of higher order bounded variation using Peano derivatives; denote these by \(V_ nB,\quad V_ nB^*,\) and the associated generalized classes by \(V_ nBG,\quad V_ nBG^*.\)

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Three Point Quadrature Rules Involving, at Most, a First Derivative [PDF]
, 1999 A unified treatment of three point quadrature rules is presented in which the classical rules of mid-point, trapezoidal and Simpson type are recaptured as particular cases.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Quasicontinuous Functions and Functions of Bounded Variation [PDF]
, 1965 The purpose of this investigation is threefold. First, since quasicontinuous functions are a generalization of continuous functions, properties of quasicontinuous functions similar to the properties of continuous functions are stated and proved.

Boundedness and unboundedness results for some maximal operators on functions of bounded variation [PDF]
, 2008 We characterize the space BV(I) of functions of bounded variation on an arbitrary interval I⊂R, in terms of a uniform boundedness condition satisfied by the local uncentered maximal operator MR from BV(I) into the Sobolev space W1,1(I).

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...
