Dissipation Can Act as a Mechanobiological Signal in Cartilage Differentiation

Dominique Pioletti, Arne Christian Vogel, Philippe Abdel Sayed

Knee cartilage is a soft tissue having viscoelastic properties. Under cyclic loadings, viscoelastic materials dissipate mechanical loadings through heat generation. In knee cartilage, this heat might not be convected because of the tissue avascularity, res ...

A sequence-dependent rigid-base model of DNA

John Maddocks, Daiva Petkeviciute

A novel hierarchy of coarse-grain, sequence-dependent, rigid-base models of B-form DNA in solution is introduced. The hierarchy depends on both the assumed range of energetic couplings, and the extent of sequence dependence of the model parameters. A signi ...

Surpassing Fundamental Limits of Oscillators Using Nonlinear Resonators

Luis Guillermo Villanueva Torrijo

In its most basic form an oscillator consists of a resonator driven on resonance, through feedback, to create a periodic signal sustained by a static energy source. The generation of a stable frequency, the basic function of oscillators, is typically achie ...

Changes in particle transport as a result of resonant magnetic perturbations in DIII-D

Holger Reimerdes

In this paper, we introduce the first direct perturbed particle transport measurements in resonant magnetic perturbation (RMP) H-mode plasmas. The perturbed particle transport increases as a result of application of RMP deep into the core. In the core, a l ...

Analyzing fluctuations in car-following

Many car-following models predict a stable car-following behavior with a very small fluctuation around an equilibrium value g∗ of the net headway g with zero speed-difference Δv between the following and the lead vehicle. However, it is well-known and addi ...

Temperature effect on connective tissue cells

Philippe Abdel Sayed, Salim Elias Darwiche

Intervertebral discs (IVD) are soft tissues that have viscoelastic behavior. Under cyclic loading, viscoelastic tissues dissipate the mechanical loading through the production of heat. In IVD, it is hypothesized that heat cannot be convected from the nucle ...

Entropy in the Coil-to-Globule Transition of Macromolecules

Carlo Maffi

The coil to globule transition is a fundamental phenomenon in the physics of macro-molecules by reason of the multiplicity of arrangements of their conformation. Such conformational freedom is the main source of entropy in the molecule and is the main oppo ...

Evidence for Columnar Order in the Fully Frustrated Transverse Field Ising Model on the Square Lattice

Frédéric Mila, Tommaso Coletta, Sandro Wenzel

Using extensive classical and quantum Monte Carlo simulations, we investigate the ground-state phase diagram of the fully frustrated transverse field Ising model on the square lattice. We show that pure columnar order develops in the low-field phase above ...

Arrested demixing opens route to bigels

Nicolas Dorsaz, Francesco Varrato, Giuseppe Foffi, Maxim Belushkin

Understanding and, ultimately, controlling the properties of amorphous materials is one of the key goals of material science. Among the different amorphous structures, a very important role is played by colloidal gels. It has been only recently understood ...

Routes to Novel Colloidal Gels

Francesco Varrato

The thesis describes how demixing of binary colloidal mixtures could be used to design new kinds of amorphous structures. We show that a rich phase behavior emerges, dependent on density (colloidal concentration) and composition (species relative populatio ...
