– We study a generalization of the one-dimensional disordered Potts model, which exhibits glassy properties at low temperature. The real space properties of inherent structures visited dynamically are analyzed through a decomposition into domains over which the energy is minimized. The size of these domains is distributed exponentially, defining a characteristic length scale which grows when lo...

Multiscale modeling of collagen fibril is carried out by incorporating the material properties of collagen obtained from steered molecular dynamics into the finite element model of collagen fibril with inclusion of crosslinks. The results indicate that the nonbonded interactions between collagen and mineral contribute to the significant enhancement of the elastic modulus of collagen fibril at a...

In the main text, we noted that the shape parameters (characteristic length, Λ, and loop radius, Ro) of the patterns only depend weakly on the deployment height. To resolve this height dependence of the pattern length scales, we have performed a series of numerical simulations where we have varied the normalized deployment height, H̄, while keeping the gravito-bending length fixed at Lgb = 3.3 c...

background: reports on the determinants of morbidity in coronary artery bypass graft surgery (cabg) have focused on outcome measures such as length of postoperative stay in the intensive care unit (icu). we proposed that major comorbidities in the icu hampered the prognostic effect of other weaker but important preventable risk factors with effect on patients’ length of hospitalization. so we a...

Objectives: Myotonic Dystrophy type I (DM1) is a dominantly inherited disorder with a multisystemic pattern affecting skeletal muscle, heart, eye, endocrine and central nervous system. DM1 is associated with the expansion and instability of CTG repeat in the 3chr('39') untranslated region of the myotonic dystrophy protein kinase (DMPK) gene located on chromosome 19q13.3. The aim of this study w...

Several methods are available for performance prediction of single phase shaded pole induction motors. A simple model, in conjunction with a more complicated and accurate model, which considers the asymmetrical windings and core loss, is used to compare the prediction methods against experimental results. Saturation is incorporated in the model. Fundamental and harmonic flux density wave distri...

In this paper we describe a new fiber-optic microphone developed as a passive acoustic sensor for traffic monitoring and vehicle classification. It is based on a fiber-optic extrinsic Fabry–Perot (FP) microinterferometer coupled to an external membrane for modulating the FP cavity length and a low coherent superluminescent diode as light source. The frequency characteristic as compared with a s...

Nuclear magnetic resonance measurements of scale dependent dynamics in a random solid open-cell foam reveal a characteristic length scale for transport processes in this novel type of porous medium. These measurements and lattice Boltzmann simulations for a model foam structure indicate dynamical behavior analogous to lower porosity consolidated granular porous media, despite extremely high por...
