The Complexity of Resolvent Resolved
, 1993 The concept of a resolvent of a prime ideal was originally introduced by J.F. Ritt along with the notion of a characteristic set. The motivation for studying resolvents comes from its connections with the birational isomorphisms that describe ...

On continuous and residual spectra of operators connected with iterative functional equations
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2006 The sum type operator $F$, given by [ F lbrack varphi brack (x) : = displaystylesum^{infty}_{u = 0} 2^{-u} varphi (2^{u} x), ] will be considered on the space $D$ of bounded real functions, equipped with the supremum norm and on its ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Oseen resolvent estimates with small resolvent parameter
, 2017 We consider the Oseen system with resolvent term in an exterior domain in R^3 , supplemented by homogeneous Dirichlet boundary conditions. Under the assumption that the resolvent parameter λ is close to zero and Re λ ≥ 0, λ different from 0, we estimate ...

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Quaternionic resolvent equation and series expansion of the $\mathcal{S}$-resolvent operator
In the present paper, we prove a resolvent equation for the $\mathcal{S}$-resolvent operator in the quaternionic framework. Exploiting this resolvent equation, we find a series expansion for the $\mathcal{S}$-resolvent operator in an open neighborhood of

Fixed Point Theory and Applications, 2010 The main purpose of this paper is to introduce and study a new class of generalized nonlinear set-valued quasi-variational inclusions system involving -accretive mappings in Banach spaces. By using the resolvent operator due to Lan-Cho-Verma associated
