Linear Algebra and its Applications, 1978 AbstractIn this paper, we prove a new sufficient condition for D-stability of a matrix. We then use it to show that (i) a nonderogatory stable matrix A has a Schwarz canonical form which is D-stable, and (ii) a nonderogatory stable matrix A has a Routh-canonical form which is totally stable.

Immune Checkpoints in Viral Infections
Viruses, 2020 As evidence has mounted that virus-infected cells, such as cancer cells, negatively regulate the function of T-cells via immune checkpoints, it has become increasingly clear that viral infections similarly exploit immune checkpoints as an immune system ...

On the equivalence of a-stability and g-stability [PDF]
Applied Numerical Mathematics, 1989 An algebraic result is obtained which enables the authors to establish the equivalence of \(A\)-stability and \(G\)-stability for one-leg methods. They obtain an alternative proof of the second Dahlquist barrier. In the following two of their results are stated: Theorem: If the polynomials \(\rho\) and \(\sigma\) are relatively prime, then \(A ...

BMC Musculoskeletal Disorders, 2019 Background The purpose of anterior cruciate ligament reconstruction (ACLR) is to restore stability to the knee. Persistent rotational laxity following ACLR has been correlated with poor outcome and graft failure. We hypothesize that anterolateral complex

Centromere protection requires strict mitotic inactivation of the Bloom syndrome helicase complex
Nature CommunicationsThe BTRR (BLM/TOP3A/RMI1/RMI2) complex resolves DNA replication and recombination intermediates to maintain genome stability. Alongside PICH, they target mitotic DNA intertwinements, known as ultrafine DNA bridges, facilitating chromosome segregation ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Bernoulli, 2013 Reproducibility is imperative for any scientific discovery. More often than not, modern scientific findings rely on statistical analysis of high-dimensional data. At a minimum, reproducibility manifests itself in stability of statistical results relative to "reasonable" perturbations to data and to the model used.

Network topology drives population temporal variability in experimental habitat networks
Population Ecology, EarlyView.Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Population Ecology, EarlyView.We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,
