We report the description of a new low cost method to create a device based on a chemically modified nanopore created on a polymeric membrane. Using Soft-Lithography and Nanofabrication it can be possible to create a nanopore on a free standing polymeric membrane. After oligonucleotide functionalization of the lumen of the nanopore it is possible to detect specific sequences of DNA, thanks to the...
Two different interface models for crystalline oxynitride on SiO2 are proposed and investigated. The two models are proposed to model oxynitride gate stacks on Si substrate with SiO2 as the interlayer film. State-free insulating interfaces were obtained by expanding the bulk oxynitride cell by approximately 12% and 1% to match the lattice constant of SiO2 along the [100] and [010] axis respectively...
Generally speaking, fluctuations and noise are unwanted factors interfering with the operation of devices and circuits, and their effect is becoming stronger as the fabrication technology feature size is decreasing. Recently, single electron tunneling (SET) circuit implementations were proposed for two building blocks that were designed for Brownian motion circuits, i.e., circuits which instead of...
There are several reasons for circuit modeling of quantum systems: the first is to establish a bridge between quantum and classical worlds, inasmuch this is possible, the second is to provide a unified view of quantum systems interacting with a macroscopic environment on the point of view of observations done on the latter, the third is the possibility of using circuit simulators to describe the performance...
Making use of a generalized Green's function technique and Landauer formalism, the temperature depended current-voltage (I-V) characteristics of C60 molecule, sandwiched between two metallic electrodes are numerically investigated. In addition, the influence of the electron-phonon coupling strength on the electronic properties of the molecule is studied. The I-V characteristics of the molecule are...
A method to classify single ion channel is presented. The classes are built up by the K-means method and a generalized entropy based classifier is herein presented.
Desmosomes are cell-cell junctions that provide mechanical strength for cells and maintain integrity of tissues in animal skins and hearts. Disruption of the desmosome like in some autoimmune diseases will therefore change the mechanical property of the anchoring cells and causing blistering. In the paper, we used Atomic Force Microscopy (AFM) to visualize the keratinocytes intercellular structure...
Presented application is based on the use of carbon nanotubes for biomolecular analysis using electrochemiluminescence (ECL) detection technique ([1]-[9]). ECL is the generation of light by electron transfer between species electrochemically generated. ECL research has led to the successful ultrasensitive analysis of biomolecules in solution and commercialisation of several generations of ECL analyzers,...
In recent years, many researchers have proposed the usage of molecular scale devices exhibiting negative differential resistance (NDR) in the realization of programmable logic circuitry. This paper deals with the utilization of one such system built from NDR based circuitry, specifically the Goto pair, in the implementation of a programmable threshold logic array (PTLA). Furthermore, the PTLA considered...
The assembly of DNA nanostructures can allow for promising nanometer-sized machines. Synthetic DNA motifs are known to assemble into a wide range of nanoarchitectures by sequence programming. For the purpose of constructing strictly-controlled biological nanomachines, we design the self-assembly system consisting of DNA strands with the ability of producing a functional molecule. In this work we demonstrate...
Systemic chemotherapy is widely used for treatment of metastatic colorectal cancer (CRC). However, many CRC patients show poor response to chemotherapy and suffered from toxicities. Thus, prediction of chemotherapy response is very important in effective therapy. In the present study, we investigated whether chemotherapy response of CRC can be predicted by nano-assisted laser desorption/ionization...
This paper gives an analyzing & discussing of Depth-first Search technology of both FCR and VCR in searching without information, and points out that, properties of FCR & VCR on searching without information. And then, it introduces a novel realization method of Depth-first Search in problem solving which sometimes we should think simultaneously over the synthetic technique combining intelligent...
The traditional Pastry design is a flat overlay network and limited-scope searching, in which all nodes have identical capabilities and responsibilities and all communication is symmetric. But in practice, because of a variety of available bandwidth and delay, each node has different capabilities. in this paper, a hierarchical Pastry network model is presented to address this limitation. Furthermore,...

And then, it gives a novel realization method of Breadth-first Search in problem-solving which sometimes we should think simultaneously over the intelligent properties of VCN,...
A strong designated-verifier proxy signature scheme was proposed to protect the original signerpsilas interests. In this scheme, the verifier was designated by the original signer. The valid proxy signature generated by the proxy signer on behalf of the original signer can only be accepted by the designated verifier and no body else can be convinced about the proxy signaturespsila validity or invalidity...
Mobile ad hoc network (MANET) is self-organizing, infrastructureless, multi-hop network. The wireless and distributed nature of MANETs and the very bad security environment in battlefield bring a great challenge to securing tactical mobile ad hoc networks. Most schemes proposed recently focus on specific security areas, such as establishing trust infrastructure, securing routing protocols, or intrusion...
A new steganalysis method is proposed to detect the exists of hidden information using character substitution in texts. This is done by utilizing Support Vector Machine (SVM) as a classifier to classify the characteristic vector input into SVM. The most important step of this detection algorithm is the construction of a proper characteristic vector. Under the prerequisite that the secret bits to be...
Quantum-behaved Particle Swarm Optimization (QPSO) is a new particle swarm optimization (PSO) algorithm. Compared with standard PSO (SPSO), it guarantees that particles converge in global optimum point in probability and this algorithm has better performance and stability. This paper introduces an improved Adaptive QPSO algorithm, puts the parallelisms crude of AQPSO and high speed of computer together,...
Currently, with the popularization of the computer and Internet technologies, electronic documents have become the most important resource in enterprises or organizations. The security of documents and protecting the information resident in these documents is of paramount importance to the organizationpsilas progress and in some cases, their survival too. Hence, electronic documents are the target...
Manufacturing Execution System (MES) links plan management and workshop control in an enterprise, which is an integrative management and control system of workshop production oriented to manufacturing process. To overcome the difficulties of traditional components retrieval method, retrieval of MES components based on ontology is put forward to prompt retrieval efficiency and recall ratio. Retrieval...
