A co-oriented foliation F of an oriented 3-manifold M is taut if and only there a map from to the 2-sphere whose restriction every leaf branched cover.

BACKGROUND Leukocyte telomere length (LTL) is considered a biomarker of human aging and based on cross-sectional studies it shortens with age. However, longitudinal studies reported that many adults display LTL lengthening. METHODS Using Southern blots, we compared cross-sectional rates of age-related LTL change across a ∼20 year age range with those based on longitudinal evaluations in three...

Given strings S1, S2, and a regular expression R, we introduce regular expression constrained sequence alignment as the problem of finding the maximum alignment score between S1 and S2 over all alignments such that in these alignments there exists a segment where some substring s1 of S1 is aligned with some substring s2 of S2, and both s1 and s2 match R, i.e. s1, s2 ∈ L(R) where L(R) is the reg...

The purpose of this study was to demonstrate a neural respiratory gating system using a paired stimuli paradigm. The N1 peak of the respiratory-related evoked potential (RREP) represents early perceptual processing of respiratory sensory information. This is similar to the N100 peak shown with tactile sensation, where the second peak amplitude (S2) of the N100 peak from the somatosensory evoked...

Myosin II is the major component of the muscle thick filament. It consists of two N-terminal S1 subfragments (‘‘heads’’) connected to a long dimeric coiled-coil rod. The rod is in itself twofold symmetric, but in the filament, the two heads point away from the filament surface and are therefore not equivalent. This breaking of symmetry requires the initial section of the rod, subfragment 2 (S2)...

P. Orlik and F. Raymond showed, in [OR, I], the following: Suppose that M is a ^-dimensional closed simply-connected manifold with an effective T1-action. Then M is an equivariant connected sum of CP2, CP2, S2x S2 and S4. In [OR, II], they studied some non-simply-connected manifolds with an effective T2-action and proved that, if the manifolds have neither fixed points nor circle subgroups as s...

The baculovirus expression vector system is considered to be a safe, powerful, but cell-lytic heterologous protein expression system in insect cells. We show here that there is a new baculovirus system for efficient gene transfer and expression using the popular and genetically well-understood Drosophila S2 cells. The recombinant baculovirus was constructed to carry an enhanced green fluorescen...
