In a 42.8 ks ROSAT HRI X-ray observation of the spiral galaxy NGC 4321 (M 100) X-ray emission from the supernova 1979C is discovered, sixteen years after its outburst, with an (0.1–2.4 keV) X-ray luminosity of Lx = 1.0 × 1039 erg s−1. No X-ray emission is observed from the three other historical supernovae in NGC 4321 (SN 1901B, SN 1914A and SN 1959E). In addition to SN 1979C, seven X-ray point...

OBJECTIVE To identify specific miRNAs involved in sepsis-induced AKI and to explore their targeting pathways. METHODS The expression profiles of miRNAs in serum from patients with sepsis-induced AKI (n = 6), sepsis-non AKI (n = 6), and healthy volunteers (n = 3) were investigated by microarray assay and validated by quantitative PCR (qPCR). The targets of the differentially expressed miRNAs w...

We examine the enumeration of certain Motzkin objects according to numbers crossings and nestings. With respect continued fractions, we compute express distributions statistics nestings over three sets, namely set $4321$-avoiding involutions, $3412$-avoiding $(321,3\bar{1}42)$-avoiding permutations. To get our results, exploit bijection Biane restricted sets $4321$- involutions which was charac...

In this paper we define and study what we call the double Catalan monoid. This monoid is the image of a natural map from the 0-Hecke monoid to the monoid of binary relations. We show that the double Catalan monoid provides an algebraization of the (combinatorial) set of 4321-avoiding permutations and relate its combinatorics to various off-shoots of both the combinatorics of Catalan numbers and...

The structure of the three pattern classes defined by the sets of forbidden permutations {2143, 4321}, {2143, 4312} and {1324, 4312} is determined using the machinery of monotone grid classes. This allows the permutations in these classes to be described in terms of simple diagrams and regular languages and, using this, the rational generating functions which enumerate these classes are determi...

We show analytically and numerically that the generation of long-lasting soliton oscillations in resonant chi(2) optical materials possesses a threshold for the amplitude of a fundamental wave. The persistent oscillations of solitary waves reported by Etrich et al. [Phys. Rev. E 54, 4321 (1996)] are found to appear for finite values of the wave amplitude.

For a sample of ten nearby barred galaxies, images at 6.75μm and 15μm of circumnuclear starbursts are being taken by ISOCAM on board of the ISO satellite. We first recall the main goals of our project, give its current status, and finally, as an example, preliminary results for NGC 4321 (M100) are presented.
