Principal Component Analysis and Related Methods for Investigating the Dynamics of Biological Macromolecules

open access: yesJ, 2022
Principal component analysis (PCA) is used to reduce the dimensionalities of high-dimensional datasets in a variety of research areas. For example, biological macromolecules, such as proteins, exhibit many degrees of freedom, allowing them to adopt ...

Changes in the structure of tethered chain molecules as predicted by density functional approach [PDF]

open access: yes, 2011
We use a version of the density functional theory to study the changes in the height of the tethered layer of chains built of jointed spherical segments with the change of the length and surface density of chains.

Regioselective chlorination and bromination of unprotected anilines under mild conditions using copper halides in ionic liquids

open access: yesBeilstein Journal of Organic Chemistry, 2012
By using ionic liquids as solvents, the chlorination or bromination of unprotected anilines at the para-position can be achieved in high yields with copper halides under mild conditions, without the need for potentially hazardous operations such as ...

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Origin of the Captodative Effect: The Lone‐Pair Shielded Radical

open access: yesChemistryEurope, 2023
We have quantum chemically analyzed the origin of the captodative effect in the dimerization of para‐substituted phenyl dicyanomethyl radicals RPh(CN)2C⋅ in the gas phase and in solution.

To Transfer or Not to Transfer an Electron: Anionic Metal Centers Reveal Dual Functionality for Polymerization Reactions

open access: yesMolecules
Catalysts with anionic metal centers have recently been proposed to enhance the performance of various chemical processes. Here, we focus on the reactivity of Co(CO)4− for the polymerization of aziridine and carbon monoxide to form polypeptoids ...
