Most of the nuclear genome of warm-blooded vertebrates is a mosaic of very long (much greater than 200 kilobases) DNA segments, the isochores; these isochores are fairly homogeneous in base composition and belong to a small number of major classes distinguished by differences in guanine-cytosine (GC) content. The families of DNA molecules derived from such(More)
We investigated the nuclear higher order compartmentalization of chromatin according to its replication timing (Ferreira et al. 1997) and the relations of this compartmentalization to chromosome structure and the spatial organization of transcription. Our aim was to provide a comprehensive and integrated view on the relations between chromosome structure(More)
Measurements of ep scattering with squared 4–momentum transfer Q 2 up to 35000 GeV 2 are compared with the expectation of the standard deep-inelastic model of lepton–nucleon scattering (DIS). For Q 2 > 15000 GeV 2 , N obs = 12 neutral current candidate events are observed where the expectation is N DIS = 4.71 ± 0.76 events. In the same Q 2 range, N obs = 4(More)
Vertebrate genomes are mosaics of isochores--namely, of long (> 300 kb), compositionally homogeneous DNA segments that can be subdivided into a small number of families characterized by different GC levels. In the human genome (which is representative of a number of mammalian genomes, and, more broadly, of the genomes of warm-blooded vertebrates), the(More)

The inclusive single and double differential cross-sections for neutral and charged current processes with four-momentum transfer squared É ¾ between ½½¼ and ¿¼ ¼¼¼ Î ¾ and with Bjorken Ü between ¼¼¼¿¾ and ¼ are measured in · Ô collisions. The data were taken with the H1 detector at HERA between 1994 and 1997, and they correspond to an integrated luminosity(More)
A new measurement of the proton structure function F 2 (x, Q 2) is reported for momentum transfers squared Q 2 between 1.5 GeV 2 and 5000 GeV 2 and for Bjorken x between 3 · 10 −5 and 0.32 using data collected by the HERA experiment H1 in 1994. The data represent an increase in statistics by a factor of ten with respect to the analysis of the 1993 data.(More)
Data from high-energy physics (HEP) experiments are collected with significant financial and human effort and are mostly unique. An inter-experimental study group on HEP data preservation and long-term analysis was convened as a panel of the International Committee for Future Accelerators (ICFA). The group was formed by large collider-based experiments and(More)
