On direct sums of Baer modules
Journal of Algebra, 2009 A ring \(R\) is called Baer if the left annihilator of every nonempty subset of \(R\) is generated by an idempotent. In a general module theoretic setting, the concept of a Baer module was defined by the present authors [in Commun. Algebra 32, No. 1, 103-123 (2004; Zbl 1072.16007)] in terms of its endomorphism ring. Indeed, a right \(R\)-module \(M_R\)

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

The direct sum problem for chamber systems
, 1995 The Direct Sum Theorem for geometries states that a geometry belonging to a disconnected diagram is the direct sum of subgeometries corresponding to the connected components of that diagram.

Two-interval even order differential operators in direct sum spaces with inner product multiples
上海师范大学学报. 自然科学版, 2017 We study two-interval singular differential equations and show that their self-adjoint operator realizations in direct sum Hilbert spaces can be enlarged by using inner product multiples.

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

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.

On the Direct Sum Conjecture in the Straight Line Model
, 1998 We prove that if a quadratic system satisfies the direct sum conjecture strongly in the quadratic algorithm model, then it satisfies the direct sum conjecture strongly in the straight line algorithm model.

Sum-Power Minimization in Multiuser Single-DF-Relay Networks with Direct Links
International Journal of Distributed Sensor Networks, 2016 Forming cooperation through relay's assistance is a promising method to realize green communication by reducing transmission power. In this paper, for multiuser single-DF-relay wireless networks with direct links, the optimal power allocation strategy ...

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 ...

Complemented Subspaces of Locally Convex Direct Sum of Banach Spaces [PDF]
, 2000 We show that a complemented subspace of a locally convex direct sum of an uncountable collection of Banach spaces is a locally convex direct sum of complemented subspaces of countable subsums.
