WebDec 22, 2024 · Simulated configurations of flexible knotted rings confined inside a spherical cavity are fed into long-short term memory neural networks (LSTM NNs) designed to distinguish knot types. The results show that they perform well in knot recognition even if tested against flexible, strongly confined and therefore highly geometrically entangled … WebMost studies on knotted polymers to date have been theoretical and computational in nature. 35–40 Over the past decade, researchers have demonstrated experimental methods of introducing knots in biopolymers via chemical synthesis, 41,42 optical tweezers 43,44 and electric fields. 45,46 The development of such techniques has ignited interest in …

WebSep 15, 2016 · Polymers in globular states [ 13 – 15, 9] and DNA in viral capsids [ 16, 17, 3, 18] are known to be highly knotted, whereas unconstrained polymers [ 15, 19, 9] or DNA in good solvent conditions are less prone to self-entanglements. The probability of knotting in dsDNA was first measured in the early 1990s by gel electrophoresis [ 20, 21 ]. Single Chain Cyclized/Knotted Polymers are a new class of polymer architecture with a general structure consisting of multiple intramolecular cyclization units within a single polymer chain. Such a structure was synthesized via the controlled polymerization of multivinyl monomers, which was first reported … See more Deactivation enhanced ATRP A simple modification to atom transfer radical polymerization (ATRP) was introduced in 2007 to kinetically control the polymerization by increasing the ratio of inactive copper(II) See more Single chain cyclized polymers consist of multiple cyclized rings which afford them some unique properties, including high density, low intrinsic viscosity, low translational See more • Polymer architecture • Branching (polymer chemistry) See more password testing autotyper

WebNov 19, 2024 · To investigate the effects of knot complexity on the sliding dynamics of ring chain in rotaxane in details, we calculated the g3 ( t) of ring chain on the knotted axial chains with different knot complexity of 0 1, 3 1, 4 1, 5 1, and 6 1. As shown in Fig. 4, the dependence of g3 ( t) on time t for different knot complexity is similar for both N ...
