Characterization of rings using direct-projective modules and direct-injective modules
Journal of Pure and Applied Algebra, 1993 A module \(M\) is said to be direct-projective if, given any summand \(N\) of \(M\) with projection \(p:M \to N\) and any epimorphism \(f: M\to N\), there is a \(g\in \text{End}_ R(M)\) such that \(gf = p\). Similarly, a module \(M\) is called direct-injective if given any summand \(N\) of \(M\) with injection \(i: N\to M\) and any monomorphism \(f: N ...

FEBS Open Bio, EarlyView.Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Rings whose modules are direct sums of extending modules [PDF]
Proceedings of the American Mathematical Society, 2009 In the main result of the paper the author shows for a ring \(R\) that every right \(R\)-module is a direct sum of extending modules if and only if \(R\) has finite type and right colocal type. Moreover, in this case \(R\) is Artinian and right serial, and every right \(R\)-module is a direct sum of uniform modules (Theorem 1).

FEBS Open Bio, EarlyView.Chemotherapy side effects significantly impact cancer survivors' quality of life. Using protein levels in blood samples from breast cancer patients before and after 12 weeks of taxane treatment, we detected treatment‐dependent changes in calcium signaling and aging pathways associated with cancer recurrence.

Directional Modulation Enhanced Retrodirective Array [PDF]
, 2015 Unlike the mathematical techniques adopted in classical cryptographic technology at higher protocol layers, it is shown that characteristics intrinsic to the physical layer can be exploited to secure useful information.

On the Implementation of a Dynamic Direction Modulation System with Vector Modulators [PDF]
International Journal of Antennas and Propagation, 2019 Dynamic directional modulation (DDM) has already proven to be an efficient technique to achieve physical layer security in wireless communications. System architectures based on vector modulators provide a flexible framework to implement synthesis methods that allow us to obtain increased security and/or independent multichannel transmissions. However,

FEBS Open Bio, EarlyView.Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...
