On the homogeneity of additive mappings
Aequationes Mathematicae, 1976 LetK be a ring with an identity 1 ≠ 0 andM, L two unitaryK-modules. Then, for any additive mappingf:M →L, the setH f :={α ∈ K ∣ f(αx)=αf(x) for allx ∈ M} forms a subring ofK, the ‘homogeneity ring’ off. It is shown that, forM ≠ {0},L ≠ {0} and any subringS ofK for whichM is a freeS-module, there exists an additive mappingf:M→L such thatH f =S.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

APPROXIMATION OF CAUCHY ADDITIVE MAPPINGS [PDF]
Bulletin of the Korean Mathematical Society, 2007 In this paper, we prove that a function satisfying the following inequality ‖ f(x) + 2f(y) + 2f(z) ‖ ≤ ‖ 2f( 2 + y + z) ‖+ 2(‖ x ‖ · ‖ y ‖ · ‖ z ‖) for all x, y, z ∈ X and for 2 ≥ 0, is Cauchy additive. Moreover, we will investigate for the stability in Banach spaces.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Stability of Functional Inequalities with Cauchy-Jensen Additive Mappings [PDF]
, 2007 We investigate the generalized Hyers-Ulam stability of the functional inequalities associated with Cauchy-Jensen additive mappings. As a result, we obtain that if a mapping satisfies the functional inequalities with perturbation which satisfies certain ...

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 ...

Updating Non-Additive Probabilities -- A Geometric Approach [PDF]
A geometric approach, analogous to the approach used in the additive case, is proposed to determine the conditional expectation with non- additive probabilities.
