Resonance and marginal instability of switching systems
We analyse the so-called Marginal Instability of linear switching systems, both in continuous and discrete time. This is a phenomenon of unboundedness of trajectories when the Lyapunov exponent is zero. We disprove two recent conjectures of Chitour, Mason, and Sigalotti (2012) stating that for generic systems, the resonance is sufficient for marginal instability and for polynomial growth of the...
متن کاملTemporal and spatial instability in neutral and adaptive (MHC) genetic variation in marginal salmon populations
The role of marginal populations for the long-term maintenance of species' genetic diversity and evolutionary potential is particularly timely in view of the range shifts caused by climate change. The Centre-Periphery hypothesis predicts that marginal populations should bear reduced genetic diversity and have low evolutionary potential. We analysed temporal stability at neutral microsatellite a...
متن کاملModulation of nonlinear waves near the marginal state of instability in fluid-filled elastic tubes
Using the nonlinear differential equations governing the motion of a fluid-filled and prestressed long thin elastic tube, the propagation of nonlinear waves near the marginal state is examined through the use of reductive perturbation method. It is shown that the amplitude modulation near the marginal state is governed by a generalized nonlinear Schr€ odinger (GNLS) equation. Some exact solutio...
متن کاملAnalysis of the frequency of microsatellite instability and p53 gene mutation in splenic marginal zone and MALT lymphomas.
AIMS Studies of the genetic characteristics of splenic marginal zone lymphoma (SMZL) have failed to identify genetic changes specific to this tumour. Microsatellite instability is a type of genomic instability associated with different types of human cancer. Although microsatellite instability is rare in B cell non-Hodgkin's lymphomas, it has been found in some specific subsets, such as margina...
متن کاملChromosome instability and translocation t(11;18) in primary gastric marginal zone B-cell lymphoma of MALT-type.
The prognosis for patients with mucosa-associated lymphoid tissue (MALT) lymphomas is good; these tumours have usually an indolent course with overall survival rates that are greater than 80% at 5-year, but some rare cases with histological transformation in aggressive diffuse large cell lymphoma have also been diagnosed. Here, we present cytogenetic results on endoscopic bioptic material of 42...
