Classification of Normal Sequences
نویسنده
چکیده
Base sequences BS m,n are quadruples A;B;C;D of {±1}-sequences, with A and B of length m and C and D of length n, such that the sum of their nonperiodic autocorrelation functions is a δfunction. Normal sequences NS n are base sequences A;B;C;D ∈ BS n, n such that A B. We introduce a definition of equivalence for normal sequences NS n and construct a canonical form. By using this canonical form, we have enumerated the equivalence classes of NS n for n ≤ 40.

GENERATING FUZZY RULES FOR PROTEIN CLASSIFICATION
This paper considers the generation of some interpretable fuzzy rules for assigning an amino acid sequence into the appropriate protein superfamily. Since the main objective of this classifier is the interpretability of rules, we have used the distribution of amino acids in the sequences of proteins as features. These features are the occurrence probabilities of six exchange groups in the seque...
متن کاملMalware Detection using Classification of Variable-Length Sequences
In this paper, a novel method based on the graph is proposed to classify the sequence of variable length as feature extraction. The proposed method overcomes the problems of the traditional graph with variable length of data, without fixing length of sequences, by determining the most frequent instructions and insertion the rest of instructions on the set of “other”, save speed and memory. Acco...

متن کاملIn silico prediction of anticancer peptides by TRAINER tool
Cancer is one of the causes of death in the world. Several treatment methods exist against cancer cells such as radiotherapy and chemotherapy. Since traditional methods have side effects on normal cells and are expensive, identification and developing a new method to cancer therapy is very important. Antimicrobial peptides, present in a wide variety of organisms, such as plants, amphibians and ...
متن کاملQuantitative Evaluation of the Lateral Sealing Ability of Normal Faults in Siliciclastic Sequences: Implication for Fault Trap in Well Gang 64, in the West Qikou Sag, China
The lateral sealing ability of a normal fault is a major factor in creating hydrocarbon traps. Therefore, a methodology for assessing the sealing ability of faults in the siliciclastic sequences of subsidence basins has been established; moreover, by using this methodology, the uncertainty inherent in hydrocarbon exploration can be decreased. Moreover, the petrophysical properties of fault roc...
متن کاملA Novel Genetic classification of SARS coronavirus-2 following whole nucleic acid and protein alignment of the isolated viruses
Background and aims: The end of 2019 has marked the year, which the human population encountered a novel virus; SARS-CoV-2 that causes a disease namely COVID-19. Here we focused on the genome and protein mutations and subsequently suggested a new classification of the SARS-CoV-2. Materials and Methods: Our study showed that some extra positions in the virus genome play a key role in the SARS-C...
