Severe acute respiratory syndrome (SARS) is a serious form of pneumonia which results in acute respiratory distress and sometimes death. In this study, we applied the reverse vaccinology approach to determine the antigenic determinant sites present on the protein. the method incorporates the prediction of antigenic sites, solvent accessible region and secondary structure, B-cell epitope prediction, and the designing of antigenic determinant. the results of the study suggested that small envelope protein and orf8 protein could be potential candidates for vaccine designing. the high scoring antigenic peptides were designed and optimized. It is inferred that peptide of small envelope protein will make a very stable and effective vaccine targeting the E protein of the virus which is responsible for the spread of the virion. this study provides a strong and a potential optimized vaccine against SARS, which has high chances of success of immunization and higher probabilities of combating the dreadful disease.

As a new type of cryptography, dna cryptography generally uses dna molecule as the information carrier and biological technology as the implementation tool. Due to its prominent advantages such as large storage capacity, high parallel computing, low energy consumption and abundant resources in nature, dna cryptography has attracted wide attention. dna cryptography involves biology, computer, mathematics and other disciplines. On the basis of the traditional cryptosystems, dna molecular computing methods are combined to form a more reliable and stable new cryptosystems, which brings opportunities and challenges to the modern cryptosystems. this paper depicts several dna cryptosystems, further analyzes the security and performance of these schemes, summarizes the shortcomings of current dna cryptography research, and looks forward to its development prospect in the field of information security. © 2020, Springer Nature Singapore Pte Ltd.

Self-assembled and spatially addressable protein microarrays are poised to become a central proteomics technology. However, it has been burdened with issues of reproducibility and standardization mainly due to the less availability of functionalized surface chemistry. Here, a microintaglio printing-based system is described that relies on coupling cdna display technique with scaffolded dna origami to print in situ-synthesized protein microarray on gold surface. A microarray of genotypes encoding the green fluorescent protein variants was patterned on gold-thiol surface using a three-way junctions (TWJs) formed from two single-stranded oligonucleotides with self-complementary sticky ends and a PDMS micromold comprising an array of uniformly arranged 4 μm-diameter holes at a density of 10,000 per mm 2.

Background: Restriction site analysis involves determining the locations of restriction sites after the process of digestion by reconstructing their positions based on the lengths of the cut dna. Using different reaction times with a single enzyme to cut dna is a technique known as a partial digestion. Determining the exact locations of restriction sites following a partial digestion is challenging due to the computational time required even with the best known practical algorithm. Results: In this paper, we introduce an efficient algorithm to find the exact solution for the partial digest problem. the algorithm is able to find all possible solutions for the input and works by traversing the solution tree with a breadth-first search in two stages and deleting all repeated subproblems. Two types of simulated data, random and Zhang, are used to measure the efficiency of the algorithm. We also apply the algorithm to real data for the Luciferase gene and the E. coli K12 genome. Conclusion: Our algorithm is a fast tool to find the exact solution for the partial digest problem. the percentage of improvement is more than 75% over the best known practical algorithm for the worst case. For large numbers of inputs, our algorithm is able to solve the problem in a suitable time, while the best known practical algorithm is unable.

Cybercrime is all about the crimes in which communication channel and communication device has been used directly or indirectly as a medium whether it is a Laptop, Desktop, PDA, Mobile phones, Watches, Vehicles. the report titled "Global Risks for 2012", predicts cyber-attacks as one of the top five risks in the World for Government and business sector. Cyber crime is a crime which is harder to detect and hardest to stop once occurred causing a long term negative impact on victims. With the increasing popularity of online banking, online shopping which requires sensitive personal and financial data, it is a term that we hear in the news with some frequency. Now, in order to protect ourselves from this crime we need to know what it is and how it does works against us. this paper presents a brief overview of all about cyber criminals and crime with its evolution, types, case study, preventive majors and the department working to combat this crime.

We have recently used genetic programming to automatically generate an improved version of Langmead's dna read alignment tool Bowtie2 [RN/12/09, Sect. 5.3]. We find it runs more than four times faster than the Bioinformatics sequencing tool (BWA) currently used with short next generation paired end dna sequences by the Cancer Institute, takes less memory and yet finds similar matches in the human genome.

dna computing-inspired pattern classification based on the hypernetwork model is a novel approach to pattern classification problems. the hypernetwork model has been shown to be a powerful tool for analysis of gene expression data. However, the ordinary hypernetwork model has limitations, such as using only binary data and operating sequentially. In this paper, we propose an improved method to process four-level data and to implement a hardware circuit for dna computing-inspired pattern classifier. We show simulation results of multi-class cancer classification from the dna microarray data for performance evaluation. Experiments show competitive diagnosis results over other conventional machine learning algorithms. Our four-level data approach also results stable and improved performance over the ordinary hypernetwork model.

In this paper we explore popular parallel computing frameworks, used in high-performance pattern-matching applications involving heterogenous architectures, specifically based on CPU/GPU infrastructures, and with particular emphasis on the Aho-Corasick multiple pattern-matching approach and its applications to dna sequence analysis and digital forensics. Our experiments showed that modern managed frameworks, such as SYCL, could serve as a viable replacement for dedicated frameworks such as CUDA and OpenCL, showcasing a comparable throughput, while being more flexible and developer-friendly. © the Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
