STRONGLY CLEAN MATRICES OVER COMMUTATIVE LOCAL RINGS
An element of a ring is called strongly clean provided that it can be written as the sum of an idempotent and a unit that commute. We characterize, in this paper, the strongly cleanness of matrices over commutative local rings. This partially extend many known results such as Theorem 12 in Borooah, Diesl and Dorsey [Strongly clean matrix rings over ...

J~#-Uc cleanness and strongly J~#-Uc cleanness of rings
A ring R is GU_cJ if U(R)=Uc(R)+J~#(R);R is (strongly) J~#-U_c-clean ring if for any a∈R,there exists g∈Uc(R),p2=p∈R,d∈J~#(R),such that ag=p+d (and ap=pa).GU_cJ rings and J~#-U_c-clean rings are proper generalizations of GUJ rings and GJ-clean rings ...

Influence of spin on the persistent current of strongly interacting electrons
The lowest eigenenergies of few, strongly interacting electrons in a one--dimensional ring are studied in the presence of an impurity barrier. The persistent current $\:I\:$, periodic in an Aharonov--Bohm flux penetrating the ring, is strongly influenced

ON STRONGLY CLEAN MATRIX RINGS [PDF]
A ring $R$ with identity is called strongly clean if every element of $R$ is the sum of an idempotent and a unit that commute. For a commutative local ring $R$ , $n=3,4$ , and $m, k, s \in {\mathbb N}$ it is proved that ${\mathbb M}_n(R)$ is strongly clean if and only if ${\mathbb M}_n(R[[x]])$ is strongly clean if and only if ${\mathbb M ...

Factorizations of Matrices Over Projective-free Rings [PDF]
An element of a ring $R$ is called strongly $J^{\#}$-clean provided that it can be written as the sum of an idempotent and an element in $J^{\#}(R)$ that commute.

Calpain small subunit homodimerization is robust and calcium‐independent
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Coherence of Currents in Mesoscopic Cylinders
The persistent currents driven by the pure Aharonov-Bohm type magnetic field in mesoscopic normal metal or semiconducting cylinders are studied. A two-dimensional (2D) Fermi surfaces are characterized by four parameters.

Monitoring circulating tumor DNA (ctDNA) in patients with operable breast cancer can reveal disease relapse earlier than radiology in a subset of patients. The failure to detect ctDNA in some patients with recurrent disease suggests that ctDNA could serve as a supplement to other monitoring approaches.
