Simplicial Ricci Flow: An Example of a Neck Pinch Singularity in 3D [PDF]
, 2014 We examine a Type-1 neck pinch singularity in simplicial Ricci flow (SRF) for an axisymmetric piecewise flat 3-dimensional geometry with 3-sphere topology. SRF was recently introduced as an unstructured mesh formulation of Hamilton's Ricci flow (RF).

Rigorous Proof of Chaotic Behaviour in a Dumbbell Satellite Model
Journal of Mathematical Analysis and Applications, 2000 A computer assisted method is applied to rigorously prove the existence of chaotic behaviour in a differential equation modelling a dumbbell satellite moving on a Keplerian ellipse. The problem is described by a second order time periodic differential equation. The satellite is composed of two equal point masses connected by a rigid massless bar. It is

A Unification of Models of Tethered Satellites [PDF]
, 2011 In this paper, different conservative models of tethered satellites are related mathematically, and it is established in what limit they may provide useful insight into the underlying dynamics.

Pharmaceutics, 2023 Intrahepatic cholangiocarcinoma (ICC) is one of the most aggressive types of human cancers. Although paclitaxel (PTX) was proven to exert potent anti-tumor effects against ICC, the delivery of PTX is still challenging due to its hydrophobic property ...

Accounting for the Effect of Internal Viscosity in Dumbbell Models for Polymeric Fluids and Relaxation of DNA [PDF]
, 2007 The coarse-graining approach is one of the most important mod- eling methods in research of long-chain polymers such as DNA molecules. The dumbbell model is a simple but e±cient way to describe the behavior of polymers in solutions.

Polymer transport in random flow [PDF]
, 2004 The dynamics of polymers in a random smooth flow is investigated in the framework of the Hookean dumbbell model. The analytical expression of the time-dependent probability density function of polymer elongation is derived explicitly for a Gaussian ...

FEBS Open Bio, EarlyView.This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Stochastic phase segregation on surfaces [PDF]
Royal Society Open Science, 2017 Phase separation and coarsening is a phenomenon commonly seen in binary physical and chemical systems that occur in nature. Often, thermal fluctuations, modelled as stochastic noise, are present in the system and the phase segregation process occurs on a
