Inteins are self-splicing protein elements. They are translated as inserts within host proteins that excise themselves and ligate the flanking portions of the host protein (exteins) with a peptide bond. They are encoded as in-frame insertions within the
Molecular evolution is usually described assuming a neutral or weakly non-neutral substitution model. Recently, new data have become available on evolution of sequence regions under a selective pressure, e.g. transcription factor binding sites. To recons
Urinary tract infections (UTIs) are a universal source of human morbidity, with millions of cystitis and pyelonephritis episodes reported annually [1]. An estimated 40-50% of all women will experience at least one UTI in their lifetime, and one in three women will have had at least one cli...
refer to genes which are predicted to be native or highly expressed. full size image figure 2 is a plot of all genes of the e. coli k-12 genome. the general form resembles the "rabbit head" trimodal shape described earlier for the genome of b. subtilis [ 53 ]. most genes belonging ...
1c). AT1 cells are flattened and squamous, and they cover more than 95% of the gas exchange surface of the alveoli and are closely associated with the surrounding endothelial capillary plexus to form the thin gas diffusion surface. AT2 cells are cuboidal and secret pulmonary surfactant, which ...
denotes the nonlinear interaction equation of nonlinear genetic regulatory network and m ( x ) d ω ( t ) is due to nonlinear intrinsic fluctuation. remark: (i) at different operation points, the linearization of nonlinear stochastic regulatory network of equation (4) will be of the form in ...
The Miocene age intrusions resulted from late Cenozoic uplift and partial melting, distributed in the older rocks in the form of migmatites, small granitic plutons (~ 1 km2), leucogranite, pegmatite dikes, and cordierite-bearing veins (Zeitler et al.1993). The dikes and veins are 1 cm to...
Despite their numerous occurrence, off-target amplicons are only one form of false-positive zOTUs that we excluded from our analysis. Contaminants in metabarcoding data of human and murine brains Having removed off-targets and other false-positive zOTUs (denoised zOTUs, chimeric zOTUs, PhiX match...
Given the increasing availability of cultural datasets in machine-readable form, this operationalization opens up new avenues to study the dynamics of visual art aesthetics at scale, over long time spans and almost in real time. As such, the approach may help to transcend the still considerable ...
The RSR 3.8 was nothing short of an all-out race car that could be delivered to the track in a ‘just add driver’ form. The Porsche Carrera RSR 3.8 racked up a catalogue of impressive international race results right from the outset, winning overall at the Spa 24 Hours, Suzuka 1000km...
