This paper presents a secure and flexible Mix-net that has the following properties; it efficiently handles long plaintexts that exceed the modulus size of underlying public-key encryption as well as very short ones (length-flexible), input ciphertext length is not impacted by the number of mix-servers (length-invariant), and its security in terms of anonymity is proven in a formal way (provabl...

crust breaking of saffron is an important operation at the first stage of growth that should be accuratly operated as in this period sprouts of saffron rise up to near the soil surface. after primary irrigation, farmers soften the soil surface by means of different cultivation implements, which enables saffron flowers arise from subsurfarce. this research was conducted to compare tillage implem...

In order to illustrate how atomistic modeling is being used to determine the structure, physical, and chemical properties of materials at the nanoscale, we present here the results of molecular dynamics (MD) simulations on nanoscale assemblies of such materials as carbon nanotubes, diamond surfaces, metal alloy nanowires, and ceramics. We also include here the results of nonequilibrium MD simul...

Using the boundary element dual reciprocity method-multi domain (DRM-MD), bound electron states and the corresponding wave functions in semiconductor quantum wires embedded in a matrix were considered. The single circular and rectangular as well as the two near circular quantum wires were analysed. In the case of two coupled quantum wires, the dependence of the resulting wave function and eigen...

We present a molecular dynamics (MD) based computer simulation model for particle bombardment of metal surfaces. In addition to the description of the atomic collision cascade initiated by the particle impact, our model incorporates the electronic degree of freedom of the target and therefore is capable of simultaneously predicting secondary ion formation in sputtering as well as ion-bombardmen...

We showcase the combination of experimental neutron scattering data and molecular dynamics (MD) simulations for exemplary phospholipid membrane systems. Neutron X-ray reflectometry small-angle measurements are determined by length density profile in real space, but it is not usually possible to retrieve this unambiguously from alone. MD predict these profiles, they require control. Both issues ...

We present results for the static potential in the confinement phase of the SU(2) Higgs model on the lattice. Introducing a suitable matrix correlation function we observe string breaking at a distance r b ≈ 1.8r0, where the length scale r0 has a value r0 ≈ 0.5 fm in QCD. The method presented here may lead the way towards a treatment of string breaking in QCD.

The McMullen Correspondence gives a linear dependence between Msequences of length ⌊ d 2 ⌋+1 and f–vectors of simplical d–polytopes. Denote the transfer matrix between g and f by Md. Recently, Björner proved that any 2×2–minor of Md is nonnegative and conjectured that the same would be true for arbitrary minors. In this paper we answer the question in the affirmative.

PURPOSE To examine the effect of induced myopia on scleral myofibroblast populations and in vivo ocular biomechanical compliance. METHODS One-week-old guinea pigs were monocularly deprived (MD) of form vision for 2 weeks. Ocular biomechanical compliance was measured in both eyes of anesthetized animals by increasing the intraocular pressure (IOP) to 50 mm Hg for 1 hour, while A-scan ultrasoun...
