During the past several years, there have been a number of advances in the computational and theoretical modeling of lipid bilayer structural and dynamical properties. Molecular dynamics (MD) simulations have increased in length and time scales by about an order of magnitude. MD simulations continue to be applied to more complex systems, including mixed bilayers and bilayer self-assembly. A cri...

Hadronic atoms are highly non-relativistic loosely bound systems of hadrons mainly formed by the Coulomb interaction. The study of these hadronic bound states has seen growing interest during recent years, because they provide important information on the behavior of QCD at low-energy. The DIRAC collaboration 1 at CERN measures the lifetime of the ππ atom, and plans to determine the ππ scatteri...

The interplay between the broken symmetry and the boundary conditions alters profoundly the electronic properties of carbon single-wall nanotubes ~SWNTs! of finite-lengths. For SWNTs (p ,q) characterized by p 5k1l , q5k2l , 0<l<k , and k51,2, . . . , the energy gaps for finite SWNTs belonging to a given family k exhibit strikingly similar oscillating patterns for even NT sections, but the gap m...

In this paper we study the influence of hard supersymmetry breaking terms in a N = 1, d = 4 supersymmetric model, in S 1 × R 3 spacetime topology. It is found that for some interaction terms and for certain values of the couplings, supersymmetry is unbroken for small lengths of the compact radius, and breaks dynamically as the radius increases. Also for another class of interaction terms, when ...

Background: Adherence to a Mediterranean diet (MD) has been quantified through various indexes that rely on full-length questionnaires, but their application in data collected with brief questionnaires has not been systematically investigated. Objective: We aimed to evaluate the ability of the commonly used MD score (MDS) to classify individuals according to their adherence to an MD when applie...

(2) Dimensionality: Generally speaking, in any particular WL problem there will be 2 char. lengths: (i) the elastic mfp, l, which is usually only weakly T -dependent and can range, typically, from a few Å to a few 1000 Å (ii) some ”phase-breaking length Lφ, e.g., an inelastic length Lin or a “magnetic length” LM ∼ √ φ0/B. The phasebreaking length can be l. Most experiments which explicitly test...

The use of molecular dynamics (MD) simulations has led to promising results unravel the atomistic origins adhesive wear, and in particular for onset wear at nanoscale surface asperities. However, MD come with a high computational cost offer access only narrow window time length scales. We propose here resort discrete element method (DEM) mitigate cost. Using DEM particles contact cohesive force...
