Integral Closures of Noetherian Integral Domains as Intersections [PDF]
Proceedings of the American Mathematical Society, 1995 Let \(A\) be a noetherian integral domain, \(\overline A\) its integral closure, and let \({\mathcal G}\) be the set of prime ideals \(P\) of \(A\) with height\((P) \leq 1\). The author provides three equivalent conditions for the equality \(\overline A = \bigcap \overline A_P\), \(P \in {\mathcal G}\). For instance, equality holds iff \(\bigcap A_P\),

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

On the integral equation of an adjoint boundary value problem of heat conduction
Қарағанды университетінің хабаршысы. Математика сериясы, 2019 An integral equation is considered, to which a nonhomogeneous first boundary value problem with an adjoint heat conduction operator is reduced. The problem is set in an infinite plane angle, that is, a boundary of the domain moves with a constant ...

Stability Properties of the Time Domain Electric Field Integral Equation Using a Separable Approximation for the Convolution With the Retarded Potential [PDF]
IEEE Transactions on Antennas and Propagation, 2011 The state of art of time domain integral equation (TDIE) solvers has grown by leaps and bounds over the past decade. During this time, advances have been made in (i) the development of accelerators that can be retrofitted with these solvers and (ii ...

The IQ‐compete assay for measuring mitochondrial protein import efficiencies in living yeast cells
FEBS Letters, EarlyView.The efficiency of mitochondrial protein import depends on the properties of the newly synthesized precursor proteins. The Import and de‐Quenching Competition (IQ‐compete) assay is a novel method to monitor the import efficiency of different proteins by fluorescence in living yeast cells.

On integrally dependent integral domains [PDF]
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1947 The subject of this paper is the simultaneous ideal theory of a pair of integral domains R and G ≥ R, of which R is integrally closed, and G integrally dependent on R. It is assumed that the quotient field L of G is a finite separable extension of the quotient field K of R.

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.

FEBS Letters, EarlyView.Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.
