Due to the peculiar nature of the underlying medium, density fluctuations in a ‘Higgs condensate’ are predicted to propagate for infinitely long wavelengths with a group velocity cs → ∞. On the other hand, for any large but finite cs there is a weak, attractive 1/r potential of strength 1 cs and the energy spectrum deviates from the purely massive form √ p2 +M2 h at momenta smaller than δ ∼ Mh ...

With 30 to 80 percent of computer work involving the use of a pointing device, engineers are constantly exploring new and better interface designs. The introduction of a force-feedback mouse, which provides high fidelity tactile cues via force output, may represent such a long-awaited technological breakthrough. However, force may also be a risk factor for musculoskeletal disorders of the upper...

Coarse-grained simulation approach is applied to provide a general understanding of various soluble, hydrophilic macroionic solutions, especially the strong attractions among the like-charged soluble macroions and the consequent spontaneous, reversible formation of blackberry structures with tunable sizes. This model captures essential molecular details of the macroions and their interactions i...

The current version of the human immunome network consists of nearly 1400 interactions involving approximately 600 proteins. Intermolecular interactions mediated by proline-rich motifs (PRMs) are observed in many facets of the immune response. The proline-rich regions are known to preferentially adopt a polyproline type II helical conformation, an extended structure that facilitates transient i...

PURPOSE Although magnetic attachment is used frequently for overdenture, it is reported that attractive force can be decreased by abrasion and corrosion. The purpose of this study was to establish the clinical basis about considerations and long term prognosis of overdenture using magnetic attachments by investigating the change in attractive force of magnetic attachment applied to the patients...

We present a re-parameterization of a popular intermolecular force field for describing intermolecular interactions in the organic solid state. Specifically we optimize the performance of the exp-6 force field when used in conjunction with atomic multipole electrostatics. We also parameterize force fields that are optimized for use with multipoles derived from polarized molecular electron densi...

This paper aims to investigate the pull-in phenomenon of functionally graded (FG) capacitive nanocantilevers subjected to an electrostatic force and thermal moment due to an applied voltage and thermal shock considering intermolecular force within the framework of nonlocal elasticity theory to account for the small scale effect. The FG nano-beam is made of mixture of metal and ceramic which the...
