Large distance expansion in the Schrödinger representation of quantum field theory [PDF]
, 1997 This thesis is concerned with an approach to Quantum Field Theory in which the states are constructed from their large distance behaviour. The logarithm of the vacuum functional is expandable as a local quantity in any quantum field theory in which the ...

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Functional evolution equations
Journal of Mathematical Analysis and Applications, 2003 The paper concerns the functional evolution equation \[ u'(t) \in B u + F(t, u_t) , \;\;t >0, \] \[ u_0(s)= \phi(s)\in C^1([-r,0];X), \] where \(X\) is a real Banach space, not necessarily reflexive, \(F : [0,\infty) \times C([-r,0];X) \to X \) is a single-valued function and \(B: D(B)\subset X \to X\) is a multi-valued nonlinear operator.

Mathematics, 2022 In this paper, we give some properties of the bi-Jensen functional equation and investigate its Hyers–Ulam stability and hyperstability. We construct a function which is bi-Jensen and is not continuous.

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.

Functional Equations for Polynomials [PDF]
Proceedings of the American Mathematical Society, 1977 The set of all continuous symmetric multilinear forms of degree m on a real topological vector space V are shown to be in one-to-one correspondence with the family of continuous scalar-valued functions on V ...

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 ...

On a Functional-Equation of A. Hurwitz
Advances in Mathematics, 1995 The paper deals with the equation \((*)\) \(G'(z) = 2 \pi ie^{2 \pi iz} G(z + 1)\) and its adjoint equation \(F'(z) = - 2 \pi ie^{2 \pi iz} F(z - 1)\) in the complex domain. It is shown that \(G_ 0(z) = \int e^{-2 \pi iuz + \pi iu^ 2} \Gamma (u) du\) and \(F_ 0(z) = \int e^{2 \pi izu - \pi iu^ 2} \Gamma^{-1} (1 + u) du\) with integration over suitable ...
