Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Nonconvex scalarization in set optimization with set-valued maps
, 2007 The aim of this work is to obtain scalar representations of set-valued optimization problems without any convexity assumption. Using a criterion of solution introduced by Kuroiwa [D.

Weak Sharp Minima in Set-Valued Optimization Problems
Abstract and Applied Analysis, 2012 We introduce the notion of a weak ψ-sharp minimizer for set-valued optimization problems. We present some sufficient and necessary conditions that a pair point is a weak ψ-sharp minimizer through the outer limit of set-valued map and develop the ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

On Inverse Function Theorems for Set-Valued Maps
, 1984 We prove several equivalent versions of the inverse function theorem: an inverse function theorem for smooth maps on closed subsets, one for set-valued maps, a generalized implicit function theorem for set-valued maps.

Radial Epiderivatives and Set-Valued Optimization
, 2009 In this article we study some important properties of the radial epiderivatives for single-valued and set-valued maps. The relationships between this kind of a derivative and weak subdifferentials and directional derivatives in the single-valued non ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Implicit Function Theorems for Non-Differentiable Mappings
, 2006 Sufficient conditions are given for a mapping to be $\gamma$-G inverse differentiable. Constrained implicit function theorems for $\gamma$-G inverse differentiable mappings are obtained. The constraints are either closed convex cones or closed subsets in

Approximation of set-valued functions by single-valued one
, 2002 Let $Σ: M → 2^Y\{∅}$ be a set-valued function defined on a Hausdorff compact topological space M and taking values in the normed space (Y,||·||). We deal with the problem of finding the best Chebyshev type approximation of the set-valued function Σ by a ...

Multivariate character process models for the analysis of two or more correlated function-valued traits [PDF]
, 2004 Various methods, including random regression, structured antedependence models, and character process models, have been proposed for the genetic analysis of longitudinal data and other function-valued traits.
