AIM2: Improved implementation of AIM
نویسنده
چکیده
We present AIM2-F , an improved implementation of AIM-F [4] algorithm for mining frequent itemsets. Past studies have proposed various algorithms and techniques for improving the efficiency of the mining task. We have presented AIM-F at FIMI’03, a combination of some techniques into an algorithm which utilize those techniques dynamically according to the input dataset. The algorithm main features include depth first search with vertical compressed database, diffset, parent equivalence pruning, dynamic reordering and projection. Experimental testing suggests that AIM2F outperforms existing algorithm implementations on various datasets.

Cyclometalation and coupling of a rigid 4,5-bis(imino)acridanide pincer ligand on yttrium.
An extremely rigid NNN-donor proligand, 4,5-bis{(diphenylmethylene)amino}-2,7,9,9-tetramethylacridan, H[AIm2] was prepared in five steps starting from 5-methyl-2-aminobenzoic acid and 4-bromotoluene. Reaction of intensely orange H[AIm2] with LiCH2SiMe3 formed deep blue Li(x)[AIm2]x (x = 2 in the solid state), while reaction with [Y(CH2SiMe3)3(THF)2] (0.5 equiv.) afforded deep blue [Y(AIm2)(AIm)...
متن کاملMiR-143 Induces Expression of AIM2 and ASC in Jurkat Cell Line
Background: Absent in Melanoma 2 (AIM2) is an intracellular microbial dsDNA sensor which plays an important role in production of proinflammatory cytokines through Apoptosis associated Speck-like protein containing a Caspase activation and recruitment domain (ASC) and Caspase-1. Micro-RNAs (miRNAs) play important roles in regulation of immune related genes. However, there is little information ...

Background and Objectives: Regular aerobic exercises along with herbal supplements can control inflammation. The aim of this study was to investigate the effect of aerobic exercises and octopamine consumption on gene changes of NLR family pyrin domain containing 3 (NLRP3), absent in melanoma 2 (AIM2) and caspase 9 in brown adipose tissue in rats after consuming deep fried oil. Materials and Me...
متن کاملAIM 2 inflammasomes regulate neuronal morphology and influence anxiety and memory in mice
Inflammasomes are the protein assemblies that consist of inflammasome sensors, adaptor apoptosis-associated speck-like proteins containing a CARD (ASC) and inflammasome caspase. Inflammasomes sense multiple danger signals via various inflammasome sensors and consequently use caspase to trigger proteolytic processing and secretion of IL-1β cytokines. Recent studies have suggested that neurons us...
متن کاملMolecular mechanism for p202-mediated specific inhibition of AIM2 inflammasome activation.
Mouse p202 containing two hemopoietic expression, interferon inducibility, nuclear localization (HIN) domains antagonizes AIM2 inflammasome signaling and potentially modifies lupus susceptibility. We found that only HIN1 of p202 binds double-stranded DNA (dsDNA), while HIN2 forms a homotetramer. Crystal structures of HIN1 revealed that dsDNA is bound on face opposite the site used in AIM2 and I...
