Positive feedback plays a key role in the ability of signaling molecules to form highly localized clusters in the membrane or cytosol of cells.Such clustering can occur in the absence of localizing mechanisms such as pre-existing spatial cues, diffusional barriers, or molecular cross-linking.What prevents positive feedback from amplifying inevitabl
ABSTRACT Genotypic methods for drug susceptibility testing of Mycobacterium tuberculosis are desirable to speed the diagnosis and proper therapy of tuberculosis (TB).However, the numbers of genes and polymorphisms implicated in resistance have proliferated, challenging diagnostic design.We developed a microfluidic TaqMan array card (TAC) that utili
Tsunami attenuation by coastal vegetation was examined under laboratory conditions for mature mangroves <i>Rhizophora</i> sp.The developed novel tree parameterization concept, accounting for both bio-mechanical and structural tree properties, allowed to substitute the complex tree structure by a simplified tree model of identical hydrau
Abstract Drilling in Barents Sea proves to be a challenging task, as this region is situated in auroral zones having high geomagnetic latitude, where magnetic interferences develop from magnetic field and magnetic materials inside subsurface are quite common.For this region, monitoring of magnetic field is utterly significant as any fluctuations ca
