A novel method of renormalization called Pacman renormalization allows us to study (unicritical) Siegel functions through Pacman-type functions. It has been used to investigate the Siegel parameters with combinatorially periodic rotation number in the main cardioid of the Mandelbrot set. It is already known that it can be defined a Pacman renormalization operator such that for Siegel pacmen, with combinatorially periodic rotation numbers, the operator is compact, analytic and has a unique fixed point, at which it is hyperbolic with one-dimensional unstable manifold. In this paper we observe that this Pacman renormalization operator is compact and analytic at any Siegel Pacman or Siegel map with combinatorially bounded rotation number. This allows us to define a renormalization operator on the hybrid classes of the standard Siegel pacmen to which we built its horseshoe where the operator is topologically semiconjugated to the left shift on the space of bi-infinite sequences of natural numbers bounded by some constant.

In this paper, the addition of admixed superabsorbent polymer (SAP) improved the microstructure and durability-related properties in a cement-based system with supplementary materials. This is an important issue in real construction projects when good durability properties are required. This study investigates the effect of SAP on the systems using cement replacement by fly ash and silica fume considering the strength properties and durability properties of paste under sulfate attack of cement-based system. The replacement considered in the study was of 10% silica fume and 20% fly ash in each case, the dosage of SAP was 0.25% of the total amount of cementitious material. The results showed that the addition of SAP in the cement-based system improved the compressive strength and reduced expansion to sulfate attack. Scanning electron micrographs showed that utilization of fly ash with silica fume and silica fume with SAP resulted in a much denser microstructure, thereby, leading to an increase in compressive strength and lower expansion under sulfate attack.

大震后通常在主震震源附近发生许多余震,虽然余震的发生机制尚不清楚,但大震破裂似乎是扰动了局部的应力场,有时形成复杂的余震断裂,在某些情况下似乎这些余震是原有的分支断层的二次形变造成的。将震后的余震活动与同震滑动作初步的比较后,认为余震不发生于主震滑动多的地方。Doser和Kanamori(1986)发现1979年10月15日英佩里尔谷地震的余震活动发生于滑动多的区域外;Hartzell和Heaton(1986)反演强震和远震资料发现,1984年4月24日摩根山地震的余震大都发生于主震最大滑动区外(图1)。这种情况符合于余震发生于主震断裂后应

AIM: Inflammatory bowel diseases (IBD) are multifactorial pathologies of unknown etiology. One susceptibility locus, IBD5, has been mapped to chromosome 5q31. We analyzed our Spanish cohorts of Crohn's disease (CD) and ulcerative colitis (DC) patients to determine whether this locus is associated with IBD, and to ascertain the main clinical phenotype influenced by this risk factor. The kind of interaction, either genetic heterogeneity or epistasis, between this IBD5 susceptibility region and the NOD2/CARD15 gene mutations was studied as well. Finally, we assessed whether this locus can predict response to infliximab therapy. METHODS: A case control study was performed with 274 CD and 211 UC patients recruited from a single center and 511 healthy ethnically matched controls. Two polymorphisms were genotyped in the IBD5 locus and three in the CARD15/NOD2 gene. RESULTS: Our results evidence association only with CD especially with the fistulizing phenotype and in the absence of NOD2/CARD15 variants (mutant allele frequency in patients vs controls: OR = 2.03, 95% CI = 1.35-3.06, P<0.01). The frequency of the IBD5 homozygous mutant genotype significantly increased in CD patients lacking response to infliximab (RR = 3.88, 95% CI = 1.18-12.0, P<0.05). UC patients overall do not show association with 5q31 polymorphisms, although a similar trend to the one observed in CD is found within the worse prognosis group. CONCLUSION: The IBD5 variants may enhance an individual carrier's risk for CD, mainly in the absence of the NOD2/CARD15 mutations and in fistulizing patients. The data presented suggest the potential role of the 5q31 polymorphisms as markers of response to infliximab.
