| 1 | An Abnormal Network Flow Feature Sequence Prediction Approach for DDoS Attacks Detection in Big Data Environment显示文摘Distributed denial-of-service(DDoS)is a rapidly growing problem with the fast development of the Internet.There are multitude DDoS detection approaches,however,three major problems about DDoS attack detection appear in the big data environment.Firstly,to shorten the respond time of the DDoS attack detector;secondly,to reduce the required compute resources;lastly,to achieve a high detection rate with low false alarm rate.In the paper,we propose an abnormal network flow feature sequence prediction approach which could fit to be used as a DDoS attack detector in the big data environment and solve aforementioned problems.We define a network flow abnormal index as PDRA with the percentage of old IP addresses,the increment of the new IP addresses,the ratio of new IP addresses to the old IP addresses and average accessing rate of each new IP address.We design an IP address database using sequential storage model which has a constant time complexity.The autoregressive integrated moving average(ARIMA)trending prediction module will be started if and only if the number of continuous PDRA sequence value,which all exceed an PDRA abnormal threshold(PAT),reaches a certain preset threshold.And then calculate the probability that is the percentage of forecasting PDRA sequence value which exceed the PAT.Finally we identify the DDoS attack based on the abnormal probability of the forecasting PDRA sequence.Both theorem and experiment show that the method we proposed can effectively reduce the compute resources consumption,identify DDoS attack at its initial stage with higher detection rate and lower false alarm rate. | Jieren Cheng Ruomeng Xu Xiangyan Tang Victor S.Sheng Canting Cai | 2018 | Computers, Materials & Continua2018，，4： | 15 |
| 2 | Influence of a nucleotide oligomerization domain 1 (NOD1) polymorphism and NOD2 mutant alleles on Crohn's disease phenotype显示文摘AIM: To examine genetic variation of nucleotide oligomerization domain 1 (NOD1 ) and NOD2 ,their respective influences on Crohn's disease phenotype and gene-gene interactions. METHODS: (ND1+326561 ) NOD1 polymorphism and SNP8,SNP12 and SNP13 of NOD2 were analyzed in 97 patients and 50 controls. NOD2 variants were determined by reaction restriction fragment length polymorphism analysis. NOD1 genotyping and NOD2 variant confirmation were performed by specific amplification and sequencing. RESULTS: The distribution of NOD1 polymorphism in patients was different from controls (P = 0.045) and not altered by existence of NOD2 mutations. In this cohort,30.92% patients and 6% controls carried at least one NOD2 variant (P < 0.001) with R702W being the most frequent variant. Presence of at least one NOD2 mutation was inversely associated with colon involvement (9.09% with colon vs 36.4% with ileal or ileocolonic involvement,P = 0.04) and indicative of risk of penetrating disease (52.63% with penetrating vs 25.64% with non-penetrating or stricturing behavior,P = 0.02). L1007finsC and double NOD2 mutation conferred the highest risk for severity of disease (26.3% with penetrating disease vs 3.8% with non-penetrating or stricturing behavior presented L1007finsC,P = 0.01 and 21.0% with penetrating disease vs 2.5% with non-penentrating or stricturing behavior carried double NOD2 mutation,P = 0.007). Exclusion of patients with NOD2 mutations from phenotype/NOD1 -genotype analysis revealed higher prevalence of 11 genotype in groups of younger age at onset and colonic location. CONCLUSION: This study suggests population differences in the inheritance of risk NOD1 polymorphism and NOD2 mutations. Although no interaction between NOD1 -NOD2 was noticed,a relationship between disease location and Nod-like receptor molecules was established. | Elisabet Cantó Elena Ricart David Busquets David Monfort Esther García-Planella Dolors González Joaquim Balanzó José L Rodríguez-Sánchez Sílvia Vidal | 2007 | World Journal of Gastroenterology2007，13，41： | 2 |
| 3 | Massive fibrous epulis——a case report of a 10-year-old lesion显示文摘The fibrous epulis, a common tumor-like lesion of the gingiva, appears in the interdental papilla as a result of local irritation. Lesions are asymptomatic and have a variable growth rate. A 75-year-old woman was referred for the evaluation of a large painless gingival mass. It had started 10 years back and has been increasing in size the last year. No bone involvement was noted. The tumor was totally removed by excision with surgical scalpel under local anesthesia without teeth extraction. The microscopic findings were suggestive of a fibrous epulis. Differential diagnosis, clinical considerations and factors to prevent recurrence are discussed. | Gabriel M Fonseca Ricardo M Fonseca Mario Cantín | 2014 | International Journal of Oral Science2014，6，3： | 2 |
| 4 | Deposition of litter and nutrients in leaves and twigs in different plant communities of northeastern Mexico显示文摘Studies on litterfall and decomposition provide estimations of decomposition rates of different ecosystems.This is key information to understanding ecosystem dynamics and changes in a scenario of global warming.The objective of this research was to assess litterfall production,the potential deposition of macro and micronutrients through leaf and twig fall as well as macronutrient—use efficiency in three forest ecosystems at different altitudes: a pine forest mixed with deciduous species(S1); a Quercus spp.forest(S2); and,a Tamaulipan thornscrub forest(S3).Total annual litterfall deposition was 594,742 and 533 g m^(-2) for S1,S2 and S3.Leaf litter was higher (68%) than twigs(18%),reproductive structures(8%) or miscellaneous material(6%).Micronutrient leaf deposition was higher for Fe followed by Mn,Zn and Cu.Macronutrient leaf deposition was higher for Ca followed by K,Mg and P.Even though P deposition in leaves and twigs was lower than other macronutrients,its nutrient use efficiency was higher than Ca,Mg or K.Altitude and species composition determine litter and nutrient deposition,with higher values at mid-altitudes(550 m).Altitude is an important factor to consider when analyzing litter production as well as nutrient deposition as shown in this study.Litter production and nutrient deposition are expected to change in a scenario of global warming. | Humberto González-Rodríguez Roque Gonzalo Ramírez-Lozano Israel Cantú-Silva Marco Vinicio Gómez-Meza Eduardo Estrada-Castillón José Ramón Arévalo | 2018 | Journal of Forestry Research2018，29，5： | 2 |
