  ABSTRACT: The problem of data and information encoding on DNA bears an increasing interest for both biological and nonbiological applications of biomolecular computing. Recent experimental and theoretical advances have produced and tested to obtain large code sets of oligonucleotides to support virtually any kind of application. In this paper, we have developed an algorithm to design DNA short-word sets based on minimum free energy (MFE) criteria. The MFE constraint is the minimum value among free energies of all the possible structures and the effective approach to control the generation of unexpected secondary structure of DNA sequences may cause error. The algorithm is constructive and directly produces the actual DNA words of the sets, unlike other academic and statistical numbers. According to the previous values, our experimental results can succeed in generating better DNA word sets based on MFE constraint. More importantly, using our results could decrease the emergence of false hybridization reaction, and improve the reliability and the scale of DNA computing.

  ABSTRACT: DNA self-assembly that is fast developed in the fields of DNA computing and nano technology has become the focus of scientific fields. DNA self-assembly is a method that uses the characteristics of base-pair to form polyhedron or super molecular structure. This is a complex progress from disordered to well-ordered, from simple to complicated. This paper mainly introduces that the DNA self-assembly technology is applied into the image encryption. In this paper, we proposed a complete design scheme of DNA tiles that is suitable for the image encryption. The DNA tiles mainly include five types, namely DNA tiles of the plaintext, DNA tiles of the encryption, DNA tiles of the cipertext, DNA tiles of the key and DNA tiles of the decryption. Through a simulate example, the effect of the image encryption algorithm is shown.

• Article: Addressing key sustainable supply chain management issues using rough set methodology

  Chunguang Bai, Joseph Sarkis, Xiaopeng Wei
  [show abstract] [hide abstract]
  ABSTRACT: Purpose – This paper aims to introduce relatively novel multi-supply chain activity overview rough set theoretic applications to aid management decision making with an especial focus on green and sustainable supply chain management. Design/methodology/approach – The methodology is a review of recent literature with extensions around rough set or neighborhood rough set methodologies for supply chain management. An overview of how the techniques can be applied to various stages of green supply chain management, selection, evaluation, development is presented in various sections. Findings – The paper finds that rough set methodology is flexible enough to be applied as a selection tool, performance measurement evaluation tool, and a development program evaluation tool. Its application to green supply chain management topics is warranted and valuable. Research limitations/implications – Limitations of the approach provide additional avenues for further research. One major limitation of the research is that a real-world application to validate the approaches is necessary. Extensions and integration with other tools can also provide avenues for improvement. Practical implications – A three-staged ecological green supplier management process may help to get a broader corporate social responsibility and general sustainability perspective on the supply chain. Management can use these tools for planning, decision making, and maintenance of green supply chain activities. Social implications – The application of sustainability and environmental issues for supply chain management has significant social impact. Originality/value – Methodologically, this is the first time that neighborhood rough set has been comprehensively evaluated as a tool for managing green suppliers. A comprehensive overview of the green supplier management process considering the sustainability factors helps researchers to identify many opportunities for further investigation.

• Article: A Summarization on Image Encryption

  Shihua Zhou, Qiang Zhang, Xiaopeng Wei, Changjun Zhou
  [show abstract] [hide abstract]
  ABSTRACT: With the fast development of the computer technology and information processing technology, the problem of information security is becoming more and more important. Information hiding is usually used to protect the important information from disclosing when it is transmitting over an insecure channel. Digital image encryption is one of the most important methods of image information hiding and camouflage. The image encryption techniques mainly include compression methodology, modern cryptography mechanism, chaos techniques, DNA techniques, and so on. In this paper, we summarize the main encryption algorithms and classify them based on the means. In particular, chaos-based and DNA cryptography-based image encryption algorithms are illustrated and analyzed in detail. Finally, the future direction in this field is discussed.

• Article: Image Encryption Algorithm Based on DNA Sequences for the Big Image

  ABSTRACT: With the fast development of Internet technology and informationprocessing technology, the image is commonly transmitted via theInternet. People enjoy the convenience and shortcut, but people haveto face to the obsession that the important image information intransmission is easily intercepted by unknown persons or hackers. Inorder to enhance the image information security, image encryptionbecomes an important research direction. An image encryptionalgorithm based on DNA sequences for the big image is presented inthis paper. The main purpose of this algorithm is to reduce the bigimage encryption time. This algorithm is implemented by using thenatural DNA sequences as main keys. The first part is the process ofpixel scrambling. The original image is confused in the light of thescrambling sequence is generated by the DNA sequence. The secondpart is the process of pixel replacement. The pixel gray values ofthe new image and the one of the three encryption templates aregenerated by the other DNA sequence are XORed bit-by-bit in turn.The experimental result demonstrates that the image encryptionalgorithm is feasible and simple. Through performance analysis, thisalgorithm is robust against all kinds of attacks and owns highersecurity.
