Comparison of Cyclic and Linear PEG Conjugates [PDF]

Bioconjugate Chemistry
Bioconjugation of polymers to proteins is a method to impart improved stability and pharmacokinetic properties to biologic systems. However, the precise effects of polymer architecture on the resulting bioconjugates are not well understood. Particularly, cyclic polymers are known to possess unique features such as a decreased hydrodynamic radius when ...

Linear, Non-Conjugated Cyclic and Conjugated Cyclic Paraphenylene under Pressure [PDF]

Molecules, 2019
The n-paraphenylene family comprises chains of phenylene units linked together by C-C bonds that are between single- and double-bonded, and where n corresponds to the number of phenylene units. In this work, we compare the response of the optical properties of different phenylene arrangements.

Linear and Radial Conjugation in Extended π‑Electron Systems

, 2020
We describe the synthesis and electronic properties of new π-conjugated small molecules and polymers that combine the linear intramolecular conjugation pathways commonly associated with organic electronic materials with the emerging properties of radial ...

Linearizing the Method of Conjugate Gradients [PDF]

SIAM Journal on Matrix Analysis and Applications, 2014
The method of conjugate gradients (CG) is widely used for the iterative solution of large sparse systems of equations Ax=b, where A is symmetric positive definite. Let xk denote the k-th iterate of CG. In this paper we obtain an expression for Jk, the Jacobian matrix of xk with respect to b.

Predictive Multi Experiment Approach for the Determination of Conjugated Phenolic Compounds in Vegetal Matrices by Means of LC-MS/MS

Molecules, 2022
Polyphenols (PCs) are a numerous class of bioactive molecules and are known for their antioxidant activity. In this work, the potential of the quadrupole/linear ion trap hybrid mass spectrometer (LIT-QqQ) was exploited to develop a semi-untargeted method

A parabolic conjugation problem with general boundary condition and a conjugation condition of Wentzel type

Karpatsʹkì Matematičnì Publìkacìï, 2013
We consider the question of existence in Holder class of a solution of an initial-boundary problem for linear parabolic second-degree equation with discontinuous coefficients with a boundary condition and a conjugation condition which are defined by ...

Numerical ranges and complex symmetric operators in semi-inner-product spaces

Journal of Inequalities and Applications, 2022
We introduce the numerical range of a bounded linear operator on a semi-inner-product space. We compute the numerical ranges of some operators on ℓ 2 p ( C ) $\ell _{2}^{p}(\mathbb{C})$ ( 1 ≤ p < ∞ ) $(1\le p < \infty )$ and show that the numerical range

A simple mathematical model for the effect of benzoannelation on cyclic conjugation [PDF]

Journal of the Serbian Chemical Society, 2011
In a series of earlier studies, it was established that benzoannelation in the angular (resp. linear) position relative to a ring R of a polycyclic conjugated π-electron system, increases (resp.
