Softening of DNA near Melting as Disappearance of an Emergent Property

open access: yes, 2020
Near the melting transition the bending elastic constant, $\kappa$, an emergent property of double-stranded DNA (dsDNA), is shown not to follow the rod-like scaling for small length $N$.

Safety Control Synthesis with Input Limits: a Hybrid Approach

open access: yes, 2019
We introduce a hybrid (discrete--continuous) safety controller which enforces strict state and input constraints on a system---but only acts when necessary, preserving transparent operation of the original system within some safe region of the state ...

Role of the particle size polydispersity in the electrical conductivity of carbon nanotube-epoxy composites

open access: yes, 2017
Carbon nanotubes (CTNs) with large aspect-ratios are extensively used to establish electrical connectedness in polymer melts at very low CNT loadings. However, the CNT size polydispersity and the quality of the dispersion are still not fully understood ...

Disorder Induced Transitions in Layered Coulomb Gases and Superconductors

open access: yes, 2000
A 3D layered system of charges with logarithmic interaction parallel to the layers and random dipoles is studied via a novel variational method and an energy rationale which reproduce the known phase diagram for a single layer.

Disorder induced transitions in layered Coulomb gases and application to flux lattices in superconductors

open access: yes, 2004
A layered system of charges with logarithmic interaction parallel to the layers and random dipoles in each layer is studied via a variational method and an energy rationale. These methods reproduce the known phase diagram for a single layer where charges

The potential of Symbiont Ba cteria in Melo melo Gastropod found in Pekalongan Waters as a source of MDR antibacterial active compound [PDF]

open access: yes, 2016
The increasing resistance of many pathogenic microorganisms against antibiotics compounds creates an alarming issue in medical world. This concern has created research opportunities in new antibiotics compounds as alternative options.

The nematic phase of a system of long hard rods

open access: yes, 2012
We consider a two-dimensional lattice model for liquid crystals consisting of long rods interacting via purely hard core interactions, with two allowed orientations defined by the underlying lattice.

Efimov like phase of a three stranded DNA (Efimov-DNA) and the renormalization group limit cycle

open access: yes, 2015
A three-stranded DNA with short range base pairings only is known to exhibit a classical analog of the quantum Efimov effect, viz., a three chain bound state at the two chain melting point where no two are bound.
